2 Claims. (Cl. 239-280) The present invention relates to improvements in fire lighting apparatus and more particularly to an improved so-called cellar pipe employed for directing fire extinguishing lluid into various inaccessible places.

The present invention encompasses improvements over my prior patents, Patent No. 2,099,799, patented November 23, 1937, for Cellar Pipe, and Patent No. 2,285,- 111, patented June 2, 1942, for Shut O Valve. Patent No. 2,099,799 discloses the general arrangement of cellar pipes as including lire extinguishing fluid, a depending nozzle carrier rotatably carried by a base and one or more nozzles pivotally carried by the nozzle Icarrier with means for effecting rotation of the nozzle carrier with respect to the base so as to direct iire extinguishing lluid in selected directions.

In cellar pipes of the prior art, such as is exemplied by my prior patent, the degree and range of fire ighting coverage by the apparatus has been limited as a result of the construction and arrangement of the component parts of the cellar pipes.

Accordingly, it is a primary object of the present invention to provide an improved arrangement wherein the degree and range of fire fighting coverage is substantially increased over prior constructions.

Another object of the present invention is to provide an improved cellar pipe construction wherein the nozzle carrier which supports the one or more nozzlescan be rotated throughout a complete revolution with respect to the supporting base therefor.

Another object of the present invention is to provide an improved arrangement of operating means for the nozzle or nozzles whereby pivoting of the latter can be accomplished without restricting the rotational position of the nozzle carrier with respect to the supporting base therefor.

Still another object of the present invention is to provide an improved cellar pipe construction which embodies nozzle means having a pair of nozzles generally oppositely directed with the angle included between the nozzles being less than 180 so that the streams issuing therefrom can be selectively directed simultaneously to one side of a iixed plane through the carrier, to opposite sides4 of the plane, or to one side of the plane and into the plane.

Another object of the present invention is to provide an improved cellar pipe construction wherein the carrier yoke for the nozzles includes an endless passageway providing for improved fluid iiow through the device and out through the nozzles carried by the yoke.

Still another object of the present invention is to provide an improved cellar pipe construction wherein the nozzles can have various tips associated therewith so as to vary the type of streams issuing therefrom.

Various other objectsand advantages will become apparent from the detailed description to follow.

Referring morev particularly to the drawings, wherein like numerals apply to like parts throughout, it will be seen that my improved cellar pipe includes a base I0 having valve means 12 connected therewith and adapted to control the supply of re extinguishing iluid tothe base,I nozzle carrier means 14 including a cap 16 rotatably supporting the same in the base 10 and further including a yoke 18 for swivelly mounting the nozzle means 2t) at the lower end of the nozzle carrier means 1.4., Operating means 22 are provided for controlling rotation of the. nozzle carrier 14 with respect to the base 10 and for controlling pivoting of the nozzle means 20 with respect to the nozzle carrier 14.

The base 10 is best shown in Figs. 1 and 2 as beingA of hollow construction shaped similarly to a T-tting. The base 10. has a vertical bore 24l and a lateral, bore 26 communicating therewith. The valve 12, to be described in detail hereinafter,l controls ow through the lateral passageway 26, and the. end. portion 28 thereof is adapted to receive a hose or the likeI so as to enable a supply of iire extinguishing uid to be `fedto the base 10. The base 10 is also formed with a pair of laterally extending blocks as at 30 and 32 on whichy the two support legs 34 and 36 arey pivotally mounted, as shown best in Figi. 3f.

As will be seen most clearly in Fig. 2, the cap 16 of they nozzle carrier means 14 is o hollow construction and has a ange 38 seated ink the recess 40 of the. baseV 10 with a gasket 42 interposed to provide a seal., The cap 16 has an upper end 44 extending out of the base 10 and externally threaded at 46. The upper and lower ends 44 and 38 of the cap are joined in. spaced, relation by the spiders or posts, 47 andthe hollow guide 56 so as not to obstruct communication from the, passageway 26' into the vertical bore 24. A ring member 48 is vertically engaged on the external threading 46 of the cap 16 and is screwed downwardly into contact with a gasket` 50 so as to hold the cap 16 within the hase 10 andL sealed at both ends thereof. The. upper end of the cap at 44 is formed with an arm 52 which rotates with the cap 16 and provides. a fulcrum at 54 as shown in Fig. 1.V The hollow guide tube 56 of the cap 16 is within the base 10 so as to be rotatable with. the cap` 16 and with respect to the hase 10,. The fulcrum 54v` and guide tube 56 are provided for a purpose to be describedv in detail here.- inafter.

The nozzle carrier means 14 includes a tube 5S of substantially elongated form including a passageway `60 therethrough. The upper end of the tube 58 is secured in the lower end of the cap 16, as at 62, by suitable Thus, the tube passageway 60 has communica: tion with the interior. bore of the base 10 and the source of fluid supply. Intermediate the. ends of the tube. 58,

a guide ange 64 is provided which has an opening therethrough adapted to be aligned with the guide tube 56. 'Ehe-lower endof the tube 58 haspthe nozzle carrier yoke 18 secured thereto as at 66, see Fig. 5. As shown best in Fig. 5, the nozzle carrieryoke 18 Includes an endless passageway68 therein communicating with the passageway of the tube 58. The yoke 18 includes spaced parallel portions 70 and 72 which are provided with threaded openings at 74 and 76, respectively, to provide access to the interior of the yoke, and a pair Vof closure discs 78 and 80 are provided for lthread-ed engagement in the openings 74 and 76.' The yoke portions 70 and 72 are formed with aligned openings at 82 and 84 for swivelly mounting the nozzle means 20 presently to be described. f

Looking now at Figs. l, and 9, the nozzle means 20 will be described. The nozzle means 20 includes a pair of nozzles 86 and 88 integrally joined together so as to have apreferred included angle of about 135. The central portion of the nozzle means body is formed with a pair of lateral openings which are threaded as at 90 and 92. A bale 94`is integrally formed within the nozzle body. yThe baffle 94 has a pair of surfaces at.96 and 98 'which mergeY at an edge 100 dividing the stream received through the opening at 90 so as to deflect it to the discharge ends 102 and 104 of the nozzles. The baile 94 is'at its other side similarly formed with surfaces at 106 fand 108 merging at an edge 110 so as to divide the stream from the opening 92 and direct the Same to the dis- Acharge ends 102 and 104 of the nozzles. A pair of sleeves 112 and 114 are threadably received in the openings 90 and 92 and have anges at 116 and 118, respectively, which engage the mouths of the openings 82 and 84, respectively, whereby the nozzle means is swivelly mounted in the lateral openings. Set screws are pro- .vided at 120 for locking the sleeves 112 and 114 with respectto the openings 90 and 92. v The outer ends of the nozzles 86 and 88 are externally threaded, as at 122 and 124', so as to receive thereon tips "126 and 128 which control the type of discharge from the nozzles. For example, the tips 126 and 128 can be similar, discharging a solid stream of fluid from each, or a fog stream from each, or the adapter tips can be dissimilar, one tip discharging one type of stream and the other tip discharging another type of stream. Moreover, tips discharging multiple streams can be mounted on either end of the nozzle. In selecting the adapter tips for the nozzle, it'is desirable to have the tips produce a balanced arrangement so that the whole cellar pipe need not be restrained from movement. As an example, one fog nozzle ortip A6 inch in diameter may be mounted at one end with a inch adapter tip issuing a solid stream on the'other nozzle While maintaining a'state of balance in the cellar pipe.

1 The operating means 22 includes an operating lever 132 which is connected with either end of the lever4134, the latter being pivotally mounted on the fulcrum 54. The lever 134 has a connecting vbar 136 pivotally connected thereto at 138. The connector bar 136 passes Vthrough the guide tube 56, the guide ring 64 and has its lower endconnected to the link 139 by the pin at 1140. The link 139 in turn is pivotally connected to the v,nozzle means 20 at the ear 130 on the nozzle 88. Thus, by manipulation of the lever handle 132, the nozzle means may be pivoted within the yoke 18 thereby directing the streams issuing from the nozzles in various directions. For example, the nozzle means 20 can be positioned as shown in Figure 1, in which case both nozzles 86, 126

and 88, 128 are directed upwardly or to one side of ahorizontal plane through the intersection of the center linesof the nozzles. In another angularly displaced position, one nozzle can be directed upwardly from that plane While the other nozzle is directing its stream into the t' plane; In still another angularly displaceid position, one nozzle can be-directed'upwardly and the `other nozzle directed downwardly with respect to the' :above referred 20 throughY the openings lery thereof, nozzle means to plane. Of course, the horizontalV plane described is merely a reference plane given by way of example only. Also, the lever handle 132 can be rotated about the vertical axis through the base 10 so as to carry the whole nozzle carrier assembly through 360 of rotation. It will be noted that, inasmuch asy the connecting bar 136 is received through the cap 16and rotates therewith, no interference to the complete rotation of the nozzle carrier means is present.

As shown in Figs. 6, 7 and 8, the valve means 12 includes a valve seat element 141 received within the lateral passage 26 of the base 10. VrA valve head 142 is rotatably carried within the valve body portion 144 in the base 10. The valve head 142 includes a seating portion 146 adapted to engage the seat 141 when the valve is in the position shown in Fig. 6. By rotation of the valve head 142, the bore at 148 can be alignedwith the seat 141 so as to'permit ow from the source into the base 10. The circular bearing ring 150 is threaded into an opening as at 151 in the base 10and has a bearing shoulder 152 which contacts the outer surface of the metal packing ring 154 which seats on the stem shoulder 156. The base 10 is formed with a stop at 158 which is engaged by shoulders and 162 integrally carried by the valve head 142 for determining the limits of rotary movement ofthe valve head for closed and open valve positions,

respectively. K

The sleeve 164 is internally threaded at 166 so as to be adapted to have a hose connected thereto. The sleeve 164 is rotatably carried onthe body element 168 which in turn is threaded into the base 10 as at 170. The gasket 172 kprovides aseal when the hose is coupled thereto. v n

A metal Ygasket is provided at 174 and is engaged against a shoulder 176 on the valve seating element. A sleeve 178 threaded into the base 10 engages the outer edge of the metal gasket 174'so asrto resiliently press thereagainst whereupon a tight seal is always insured between valvevseat `141 and seating portion 146 when the latter is in its closed or shut-oit position. v

From the foregoing, r`the operation of my improved cellar pipe will be obvious. Control of the flow of fluid from the source thereof is provided by means of the valve means 12, as best'shown in Fig. 6.y The fluid ows from the valve means 12 into the cap 16 and downwardly through the tube passageway 60 into the yoke passageway 68 and from there into the nozzle means 20Y wherein the streams are divertedby means of the baie 94 so as to pass to both of the nozzle discharge ends. The endless -yoke passageway 68 aids in insuring that an even, steady will be forced into nozzle means 90 and 92. The tube 58 can be rotated with respect to the base 10 by manipulation of the lever handle 132, while the angular positionings of the nozzles 86 and 88 can be adjusted by pivoting of the lever-handle 132 with respect to the fulcrum 54.

As this invention may be yembodied in several forms without departing from the spiritor essential characteristics theerof, the present embodiment is therefore illustra-` tive and not restrictive, since the scope of the invention is defined by the appended claimsrather than by the description preceding them, and all changes that fall within the metes andbounds of the claims or that form their functionalY as-welldas'conjointly cooperative equivalents, are therefore intended to be embraced by these claims.
