As will hereinafter appear, hood latches embodying the present invention are of the type which include a latch keeper means adapted to be secured to and to depend from the front end of a hood cover, and a latch bolt means adapted to be secured to a stationary part of the hood at the front end thereof for the releasable retention of said latch keeper means. To effect the release of the latch keeper means from its retention by the latch bolt means, manually operable release means accessible at the front end of the hood may be provided, as in the embodiment of the invention illustrated in Figs. 1 to 6 inclusive and in the embodiment of the invention illustrated in Figs. 10 to 14 inclusive, or.
manually operable release means accessible at the instrument panel may be provided, as in the embodiment of the invention illustrated in Figs. 7 to 9 inclusive.
Referring first to the embodiment of the invention as illustrated in Figs. 1 to 6 inclusive, the latch keeper means thereof comprises a mounting plate 12 adapted to be bolted or otherwise rigidly secured, as at 13, to the lower surface of a ledge 14 or the like extending across the hood cover at the front end thereof. Rigidly secured to said mounting plate and depending at right angles therefrom is a latch keeper 15, which may be and here is in the form of a metal strip or strap of sufficient thickness to give it the desired strength and rigidity: As here shown (see Fig. 2), the upper end portion of the latch keeper is longitudinally slit to provide a pair of legs 16, which are bent into laterally spaced and generally parallel relationship and which extend through suitable slots in the mounting plate 12. As best shown in Fig. 2, the upper ends of such legs are rigidly secured, by any suitable means, to a sheet metal disc 17 lying Within a depression with which the mounting plate 12 is provided and which disc is welded or otherwise'rigi dly secured to said mounting plate.
Surrounding the latch keeper 15, with its upper end Patented July 24, 1956 bearing against the mounting plate 12, is a coiled spring 19, the lower end of which bears against a retainer cup 20 slidably mounted on said latch keeper. To limit the extent of such sliding movement, and thereby to limit the extent to which said coiled spring can be compressed and expanded, the latch keeper 15 is here provided with a longitudinally disposed slot 21 (Fig. 3), and the retainer cup 20 is provided with two convergently related tongues 22 extending into such slot, the tongues 22 being economically formed in the present embodiment of the invention, as integral parts of the bottom wall of the retainer cup. As shown in Figs. 2 and 3, the coiled spring 19 is normally under suflicient compression to maintain the retainer cup 20 at the lower end of the latch keeper slot 21, and as shown in Fig. 5, said spring is further compressed upon the movement of the hood cover to closed position. As a result, upon the release of the latch keeper 15 from its retention by the hereinafter described latch bolt means, when access is desired to the engine compartment within the hood, the coiled spring 19 is effective to automatically raise the front end portion of the hood cover a suiiicient distance to enable further raising of the cover to be easily and conveniently manually effected.
For its releasable retention by the hereinafter described latch bolt means, the latch keeper 15 is provided with a series of ratchet teeth 24 along one side edge wall of its lower end portion, as best shown in Fig. 3, said teeth being inwardly oifset with respect to the upper portion of such side edge wall, in the present embodiment of the invention. For guiding purposes, as will hereinafter appear, the opposite side edge wall of the keeper, along the lower end portion thereof, is inwardly beveled, as at 25, with such inwardly beveled side edge wall portion merging with the rounded bottom edge wall 26 of the keeper, as best shown in Fig. 3.
The latch bolt means, for the releasable retention of the latch keeper 15, includes a suitable mounting plate adapted to be bolted or otherwise rigidly secured, as at 28, to a ledge or the like 29 of the hood within the front end portion thereof. In the present embodiment of the invention, and as best shown in Figs. 2 and 3, said mounting plate comprises a generally flat, rectangular top, portion 30 and a depending housing-forming flange 31 of continuous form and which surrounds a generally rectangular opening 32 with which the mounting plate is provided for the reception of the latch keeper when the hood cover 11 is in closed position. As here shown, the top portion 30 of the mounting plate rests upon the hood ledge or the like 29, which is provided with a suitable opening to receive the depending flange 31 of the mounting plate and also, certain other parts, hereinafter described, of the latch bolt means.
Pivotally mounted within one end portion of the generally rectangular housing formed by the depending, continuous flange 31 of the latch bolt mounting plate is a pawl 35 for cooperative engagement with the ratchet teeth 24 of the latch keeper 15. As here shown, said pawl consists of a rigid metal strap having one end portion thereof bent into circular shape, as at 36, for the reception of a pivot pin 37 extending across said housing and having its ends mounted in apertures in opposed portions of the flange 31 by which said housing is formed, and having its free end portion disposed for cooperative engagement with the latch keeper teeth 24, the end edge 38 of such free end portion preferably being of beveled form, as shown in Figs. 3, 4 and 5. To provide a resilient mounting of the pawl 35, and thus to enable it to be selfaccommodating with respect to the latch keeper 15 and the ratchet teeth 24 thereof, a bushing 39 of rubber or other elastic material may be interposed between the pivot pin 37 and the circular end portion 36 of the pawl, 'as bestshown in Fig. 4.
' To yieldably urge the pawl 35 to swing about its pivot pin 37 in a direction for its releasable retention of the latch keeper 15 when the hood cover 11 is in closed position-a clockwise direction as viewed in Figs. 3, 4 and 5, a coiled tension spring 41 has one of its ends connected to said pawl, or to a part connected thereto, and its other end connected to the latch bolt mounting plate. As here shown, the upper end of said spring is hooked or otherwise suitably connected to a depending lug 42 with which the top portion 30 of said mounting plate is integrally provided, and the lower end of said spring is hooked or otherwise suitably connected to the upper end portion 43 of a pawl release handle 44, the upper end portion of such handle being riveted or otherwise rigidly secured to said pawl. To limit such (clockwise) movement of said pawl, and thereby to enable the spring 41 to normally locate the free end portion of the pawl in position for cooperative engagement with the latch keeper teeth 24 upon the closing of the hood cover 11, the upper end portion of the pawl release handle 44 is here provided on opposite sides of the pawl with stop lugs 45 for abutting engagement with extensions 46 of the mounting plate housing flange 31. If desired and as here shown, the flange 31 also may be provided with a set of extensions 47 for engagement by said stop lugs 45 in limiting movement of said pawl, and hence of the handle 44 secured thereto, in the opposite or pawl releasing direction, all as shown in Figs. 3, 4 and 5 and as will be readily understood.
As thus far described, it will be evident that the latch keeper mounting plate 12 is to be so located on the hood cover 11, and that the top portion 30 of the latch bolt mounting plate is to be so located in the hood 10, that when the hood cover is swung downwardly into closed position relative to the engine compartment of the hood, the depending keeper bolt 15 will enter the opening 32 of the latch bolt mounting plate and also, of course, the opening of the rectangular housing thereof. As the hood cover reaches closed position, the latch keeper teeth 24 are so located with respect to the latch bolt pawl 35 that such pawl is caused by its spring 41 to firmly but resiliently engage one of said teeth, with the consequent retention of the keeper and hence the retention of the hood cover in closed position. In its downward movement into cooperative latching relationship with the latch bolt pawl 35, the latch keeper 15 is guided by its rounded bottom edge 26 and by its inwardly beveled side edge wall 25 and also, by the rounded upper end portion of that part of the mounting plate housing flange 31 which is in opposing relation to the circular pivoted end portion 36 of the pawl 35. Moreover, because of the resilient mounting of said pawl, any alignment variations between the latch keeper and its cooperative latch bolt that are likely to occur are automatically taken care of, including misalignments in the direction of the longitudinal axis of the hood 10, misalignments transversely thereof, and diagonal misalignments. As best shown in Fig. 6, the pawl 35 has a width but slightly less than that of the housing opening, so that such. pawl is efiective for engagement with the latch keeper teeth 24, regardless of the position of the latch keeper in the opening 32 of said housing. A further feature of the resilient mounting of the pawl 35 is that it not only compensates for misalignment between the latch bolt and the keeper but it also firmly holds the latch keeper, and hence the hood cover 11, against play or lost motion, as will be evident from Fig. 6. Still another feature of the present hood latch is the provision of a series of latch keeper teeth for latching engagement with the latch bolt pawl 35, as this provides, of course, a series of closed positions in which the hood cover can be held, and thus an automatic and effective takeup for the cover, as will be readily understood.
To release the latch keeper 15, when access is desircd to the engine compartment of the hood, the pawl handle 44.is grasped andmoved in a direction to move the pawl 35 from its retaining engagement with the latch keeper teeth24, or in a direction to the right, Figs. 3 and 5,
with access to said handle being afforded through the grille bars 49, Fig. 1, in the present embodiment of the invention. Upon the release of the latch keeper 15 from its retention by the latch bolt pawl 35, the front end portion of the hood cover is automatically raised a slight distance, such as to that indicated in dot-dash lines, Fig. l, by the lifting spring 19 which, as shown in Fig. 5, is under considerable compression, between the latch keeper mounting plate 12 and the top portion 30 of the latch bolt mounting plate, when the hood cover is in closed position. From such partially raised or elevated position, the hood cover can be easily and quickly swung to fully open position, in which it is releasably held by means customarily provided therefor.
For safety purposes, the present hood latch has associated with it a hook-type catch 51, such as is now in more or less common use. As said safety catch forms no part of the present invention, it will sufiice to say that as here shown, the upper end portion of said catch is pivotally mounted, at 52, to a depending lug of the latch keeper mounting plate 12, and that by means of a coiled spring 53 connected to the upper end portion of the catch and to said latch keeper mounting plate, the hook portion of the catch is yieldingly held in a position to underlie the top portion 30 of the latch bolt mounting plate. As a result, the safety catch is automatically eflective to limit upward swinging movement of the front end portion of the hood cover, thus making it necessary to manually swing the catch out of the way before the hood cover can be appreciably opened. For such swinging movement of the catch, it is provided with a lateral extending lug 55 which can be readily grasped when it is desired to pull the catch to an out-ofthe-way position.
Instead of providing a handle accessible at the front of the hood for effecting the release of the latch keeper 15 from its retention by the latch bolt pawl 35, such as the handle 44 of the embodiment of the invention of Figs. 1 to 6 inclusive, a flexible pull cable, having an operating knob within the interior of the automobile, can be provided, if desired, for the release of the latch keeper.
Such a pull cable is shown in Figs. 7, 8 and 9, wherein the front end of the cable 60 is suitably connected to a bracket 61 riveted or otherwise rigidly secured to the pawl 35a and wherein the rear end of the cable is provided with a pull knob 62 adjacent the instrument panel of the vehicle and thus in a position conveniently accessible to the vehicle driver. As will be readily understood, when the cable 60 is pulled rearwardly, the pawl 35a is moved from its retaining engagement with the teeth 24a of the latch keeper 15a, thus releasing the latch and permitting the hood cover 11a, Fig. 9, to be swung to open position. As will be evident from Figs. 7 and 8, the latch thereof is identical with that of Figs. 1 to 6 inclusive, except for its pawl release means.
Referring now to the embodiment of the invention illustrated in Figs. to 14 inclusive, it will be noted that it differs from the embodiment of Figs. 1 to 6 inclusive chiefly in the means by which the latch bolt pawl is releasably held in engagement with, and released from, the latch keeper teeth.
Therefore, as in the latch of Figs. 1 to 6 inclusive, the latch of Figs. 10 to 14 inclusive has a latch keeper means which includes a mounting plate 12b for rigid securement to a part 14b of the hood cover 11b, a latch keeper 15b depending from said mounting plate and provided with ratchet teeth 24b along one side edge wall of its lower end portion, and a coiled compression spring 1% surrounding said latch keeper for automatically lifting the front end portion of the hood cover a short distance upon the release of the latch keeper, the upper end of said spring bearing against the mounting plate 12b and the lower end of said spring bearing against a retainer cup which has limited slidable movement along said latch keeper.
Furthenas in the latch of Figs. 1 to 6 inclusive, the
latch of Figs. 10 to 14 inclusive has a latch bolt means which includes a mounting plate having a top portion 30b and a depending housing forming flange 31b, the top portion of said mounting flange being adapted for rigid securement to a ledge or the like 2% of the hood within the front end portion thereof. Pivotally mounted within said housing, on a pivot pin 37b, is the circular end portion 36b of a pawl 35b for retaining engagement with the ratchet teeth 24b of the latch keeper 15b. As before, a rubber or other elastic bushing 3% may be interposed between the circular end portion 36b of the pawl and its pivot pin 37b, to thereby provide a resilient mounting of the pawl and thereby enable it to be selfaccommodating with respect to the latch keeper 15b and its ratchet teeth 24b.
As thus far described, it will be evident that the latch of Figs. 10 to 14 inclusive is substantially identical with the latch of Figs. 1 to 6 inclusive, although it will be noted from Fig. 10 that the mounting of the latch keeper 15b is such as to cause it to be rearwardly inclined, a disposition which enables it to better cooperate with the latch bolt pawl 35b, as will hereinafter more fully appear.
Referring now to the chief differences between the latch of Figs. 10 to 14 inclusive and the latch of Figs. 1 to 6 inclusive, it will be noted that the latch of Figs. 10 to 14 inclusive has a pawl-releasing shaft which includes a pivoted end portion 65 journalled in a pair of spaced lugs 66 depending from and integral with the top position 30b of the latch bolt mounting plate, a handleforming free end portion 67 which is here located adjacent the front end of the hood 10b and conveniently accessible through the space 68 between the grille bars 4%, Fig. 10, and an intermediate portion 69 extending through an elongated slot 70 in the angularly disposed free end portion of a laterally extending arm 71 of a bracket 72 riveted or otherwise rigidly secured to the pawl 3511. As best shown in Figs. 10 and 12, the pivoted end portion 65 of the pawl-release shaft is located at the rear of the mounting plate housing and extends transversely of the longitudinal axis of the hood; the intermediate portion 69 of said shaft is located along one side of said housing and thus extends forwardly from said pivoted end portion at substantially right angles thereto; and the handle forming free end portion 67 of said handle extends downwardly from said intermediate portion, at. substantially right angles thereto, and then forwardly to the front end of the hood.
To normally urge the pawl-release shaft about the axis of its pivoted end portion 65, in a direction to cause the pawl 35b to cooperatively engage the latch keeper teeth 24b when the hood cover 11b is in closed position, a coiled torsional spring 74 surrounds such pivoted shaft end portion, with one end 75 of said spring having bearing engagement with the adjacent mounting plate lug 66 and the other end of said spring being hooked about and thus having bearing engagement with the intermediate portion 69 of said shaft. Thus, the effect of said spring, acting through said shaft and the bracket arm '71, is to normally urge the pawl 35b in a clockwise direction, Figs. 11 and 13, with the pawl normally occupying the full line position shown in such views for latching cooperation with the latch keeper teeth 24b. To limit such clockwise movement of the pawl 35b, the bracket 72 which is secured to said pawl, is provided with a pair of stop lugs 45b for abutting engagement with a pair of extensions 46b of the mounting plate housing flange 31b, Fig. 11, and to limit reverse or keeper-releasing movement of said pawl, said housing flange is provided with another pairof extensions 47b for engagement with said bracket stop lugs 45, as in the latch of Figs. 1 to 6 inclusive.
To release the pawl 35b from its retaining engagement with the latch keeper teeth 24b, when access is desired to the engine compartment of the hood 1%, it is merely necessary to lift to the dot-dash line position, Fig. 10, the handle-forming front end portion 67 of the pawl re- 7 lease shaft, as this causes the intermediate shaft portion 69 to ride up the inclined slot 70 in the bracket arm 71 and thus swing said arm and the pawl 35b in a counterclockwise, keeper-releasing direction, Figs. 11 and 13. Upon such release of the latch keeper 15b, the lift spring 1% automatically effects partial elevation of the front end portion of the hood cover 11b, with full elevation thereof being thereafter manually possible upon the movement of the safety catch 51b to an out-of-the-way positron.
Upon such elevation of the hood cover lib and its depending latch keeper 15b, the latch bolt pawl 35b is automatically returned by the torsion spring 74 to its normal, full line position, Fig. 13, for latching cooperation with the latch keeper 15b when the hood cover is next lowered to its closing position.
To those skilled in the art to which the present invention relates, other features and advantages of hood latches embodying the present invention will be evident. Other embodiments than those here illustrated also will be evident to them, such as embodiments, for example, in which the latch keepers are transversely disposed relative to the longitudinal axes of the hoods and embodiments in which the latch keeper means are carried by the hoods and the cooperating latch bolt means by the hood covers.
