COIN OPERATED VENDING MACHINE Emma A. Laughery, Chicago, Ill.

Application March 14, 1935, Serial No. 11,089 Renewed August 30, 1937 4 Claims. (01. 312-56) This invention relates to an apparatus from articles to be vended, such as newspapers A, are which newspapers, periodicals or other selected placed upon a suitable inclined runway I4, and commodities may be dispensed. these are pressed forward by a follower plate An object of this invention is to provide means I5 to which are pivotally mounted rollers I5 5 for effecting the easy egress of a newspaper or which operate on the runway I4. The plate 15 is other article from a Vending machine when opfurther pressed by means of fingers l6, I! which erated as intended, but which prevents the inare urged forward by means of springs l8, l9,[ sertion of any implement through the delivery respectively. chute for withdrawing articles therethrough. These newspapers A or other commodities are Another object is to provide an improved mechpressed forward against a front plate 20 which anism for lifting a single article with each actu carries a ledge 2| upon which the forward article ation of the mechanism after release of the same rests. In front of the plate 20 are guides 22 on depositing the proper coin or coins. whereon slides a carriage 23 (Fig. 2) to which is Another object is to provide means for returnattached a chain 24 passing over a pulley 25.

Preferably two of pull device for operating a carriage which pairs of rollers 23 are pivotally secured to the forms part of the dispensing mechanism. truck which rolls along the guideway upon 0p- Still another object is to provide means for posite sides of the slot. An operating knob 29 closing the coin slot against the insertion of coins connected to the truck extends through the slot when operation of the dispensing mechanism has to the front side of the machine housing. Thus once been started. it will be seen that the chain and associated parts These and other objects, as will hereinafter are entirely closed within the housing with the appear, are accomplished by this invention which exception of the operating knob so as to be prois fully described in the following specification tected against tampering and against the eleand shown in the accompanying drawings, wherements. in- The lifting of the newspaper or other article, Fig. 1 is a perspective view of a coin operated particularly when not too heavy, is accomplished, 3O vending machine for newspapers and the like; as in the patent above referred to, by means of a 50 Fig. 2 is an enlarged section on the line 2-2 series of pins 30 which are carried upon a rock of Fig. 1; shaft 3|, each of the pins operating in a slot Fig. 3 is a detail in elevation of a pawl for lift- 32 (Fig. 6) The method of mounting and operating newspapers from the machine, the pawl being ing these pins has been fully described in the 35 here shown locked in an inoperative position; above mentioned patent so that it will not here 35 Fig. 4 is a similar view showing the pawl in opbe repeated. One of the aspects of the present erative position; invention relates to the form of these pins. By Fig. 5 is an end view of the needle shown on making them pointed, tapered and of triangular line 5 of Fig. 2; cross section with the fiat portion of the triangle 40 Fig. 6 is an enlarged vertical elevation, partly on top (see Fig. 5) it is found that they are much 40 in section, showing the coin chutes and associated more effective for lifting the articles without tearparts; and ing or injury.

Fig. 7 is a fragmentary section on line I of Avertical member 32 (Figs.2and 6) is secured Fig. 6. at each side of the housing and. has aseries of My present invention is concerned with various teeth on its front edge adapted to be engaged 5 features of improvement applicable to the type of by a pawl (not shown) acting in a well-known vending machine which is shown and described in manner to prevent the carriage from returning, Patent No. 1,638,413, granted Aug. 9, 1927. Many once it has started, until the carriage reaches the details of construction there disclosed are thereupper limit of its travel.

0 fore not repeated in the present drawings. For heavier articles, such as magazines, it may In the machine here illustrated I utilize a be desirable to supplement the pins with pawls housing having a front wall 8, a rear wall 9, a 33 (Figs. 3 and 4), each of which is pivotally bottom l0, end walls I l, and a hinged top I2 mounted on a pin 34 secured to the carriage 23. adapted to swing about a pivot I3 and to be suit- Each pawl is formed with an ear 35 extending ably locked by a means not shown. A stack of from one side to engage the bottom of the car- 55 riage, whereby to serve as'a'limiting stop to the outward swing of the pawl into'operative position, as shown in Fig. 4. Alongside each pawl lies a locking member 36 having a slot 3'! through 38 connects a lug 36 on the. member 36 with a lug 33 on each pawl." "Ihis spring urges the pawl 33 toward its operative. position, and the member 36 toward the loweredpositionof Fig. 4.

The member '36alsohas a laterally extending lug 36 which is adapted to engage ;a' notch "59 which is pivotally mounted on a pintle'60 (Fig. W

' 2) In connection with the shield is a springil 33 in the pawl, as shown in Fig. 3, to hold the pawl in an inoperative position.

It will be apparent that when a A" is to be vended, the lifting pawls' 33 will be released so as to advance to operative position. At other times when lighter articles are article, the springs 38. yielding suffieiently for this purpose. 1 r

In Figs. 6 and? the coin chutesare shown in detail Thus the chute 39, 40 may be a penny chute, while the chute 4|, 42 may be a nickel 7 chute. The number of pennies to. be taken through the penny chute may be adjustably'fixed by the position of a coin adjusting lever 43 so as to receive no pennies, or one or morer pennies; As shown in Fig. 6, this lever is adjusted to receive two pennies 44, and if another'penny as '45: --.is inserted it will pass down an overflow chute A6 to a return chute 41 (Figs. 1 and '7) where the pennies will be returned to'the outside whereby they are returned to the depositor. Similarly, if there be the insertion 'of a nickel 48 more ,than is required for thearticle to be vended, that nickel will be passed down the nickel overflow slot 49 to areturn'chute .50 (Figs. 1 and'6) for return to the. depositor. i I

Another aspect of this invention relates to a means for closing the coin slot at the front of the .box so that no more coins can be inserted after thecarriage23 has started its upward movement. To do this I have provided a lever 51 'pivotally mounted at 52 which engages and is pressed'down from the dotted line position to the full line position of Fig. 6 by means'of. a bearing 53, or other partof the carriage when the latter is down.

The lever '5! is connected bymeans of a link .54 with a lever 55 near the top of the machihe,
