This invention relates to improvements in angle cock holder and pipe anchor. 1

In the operation of railway cars, the usual train pipe is supplied with an angle cock at the ends thereof, which angle cocks are required to be held in a definite position with respect to the vertical. It iscustomary'to anchor the train pipe adjacentthe angle cock to prevent the pipe from moving lengthwise but a certain amount of leeway is necessary in allowing for the position of the angle cock, longitudinally, with respect to the end of the car. As is well known, the train pipe couplings are of such type that, in the event they arenot uncoupled by hand, they will uncouple automatically when two adjacent ,cars are pulled apart. In the latter event, the couplings-naturally straighten out and in "so doing, tend to lift or tilt the angle cocks upwardly with the result that there is considerable danger of breaking the nipples to which the angle cocks are attached. 7

One object of my invention is to provide a simple, eiilcient and inexpensive angle cock holder which will positively minimize any tendency of the angle cock to tilt when the hose couplings are pulled apart and which angle cock holder'is also adaptable or adjustable for all variations in location of the angle cock which may occur in serv- Another object of my invention is the provision of means for efi'ectively holding not only the train pipe but the signal pipe by means of a single key.-

- Other objects of the invention will more clearly appear from the description 'and claims hereinafter following.

rangement shown in Figure 3. Figure 5 is In the drawings forming a part of this an end elevational view and Figure 6 is a side elevational view of a two-pipe anchor showing my improvements in connection there'- with and as the anchor is employed underneath the car on the needle beams or the like. Referring first to the construction illustrated in Figures 1 and 2, 1O denotes the end sill or end block or striking plate of a railway car, to which my improved angle cock holder designated generally by the reference character A, is adapted to be attached. Said angle cock holder A, as shown, is provided with a mainhorizontally eX- tending flange 11,.vertical flange 12 by which it is riveted to the end sill or other end portion of the'car, and vertical longitudinally extending reinforcing rib 13. At its outer end, the holder is formed with a heavy depending loop 14 through which extends a pipe-receiving opening 15. Said opening 15 is elongated as clearly shown in Figure l with the greatest dimension thereof inclined from the vertical to correspond with the prescribed relation of the centers of the train pipe 16 and signal pipe 1'2. Said opening 15 is of major width at its central portion and at the upper end thereof is provided with bearings 18-18 for the train pipe and at the lower end with otherbearings 1919 for the smaller signal pipe 17 The width of the opening 15 is made such that the larger train pipe 16 with a coupling thereon may pass readily therethrough, i

' Extending transverse to the pipe opening 3 15 are retaining means in the form of key slots 20-20 to accommcdatea tapered key 21; The slots 20 each have a flat bearing face 22and an inclined face 23, the inclined faces 23 being oppositely disposed as shown cleara ly in Figure 1.: The faces 22 of the slots'will be located below thesurface of the pipe 17 so that, when the key 21 is driven home as shown in Figure 1, the two pipes 16 and li 'iwill be spread apart and tightly against their respectivebearings and thekey 21 will be normally clear of all the surfaces 22 and 23. The

key 21'is preferably of thattypehaving the narrowerend slit and pro'videdwith a bendable tang 24 to prevent the key from coming out accidentally. The blunt tang 25 may be employed to hammer the key out when desired. With the arrangement shown, it will be seen that upon any shifting of the key or pipes, a three-point contact will be obtained for the key, two of the points being with the pipes and the third point with. one of the faces 22 of the key slots. It will also be observed that the construction shown may be employed with only a single pipe, the key being entered from the proper side and driven home within the slots as will be understood.

On the outer end of the train pipe 16, in Figure 2, is shown the usual hexagonal nut 26 of the standard angle cock, the upper face 27 of the nut extending horizontally as required. To prevent the angle cock from tilting upwardly when the couplings are pulled apart, I have provided a lug 28 on the holder A which is extended longitudinally parallel to the train pipe, said lug 28 being of a width approximately equal to the width of the nut face 27 Said lug 28, at the point where it is united with the main parts of the holder, as indicated at is offset upwardly so as to leave a space 29 between the inner face thereof and the upper face of the nut 26. In actual practice, the angle cock holder A will be made of malleable iron so that the lug 28 thereof will be bendable and the outer end thereof 28 may be adjusted up or down by means of a hammer or other simple tool so as to provide a backing for the hexagonal nut. It will also be observed that by offsetting the lug 28 as above described, adjustments may be made for all variations which will occur in service as regards the inward or outward displacement of the nut and variations in the vertical height of the top fa ce thereof. Obviously the arrangement shown does not add materially to the expense of the angle cock holder and serves effectively to prevent breaking of the nipples to which the angle cocks are attached.

In the arrangement shown in Figures 3 and 1, the angle cock holder A is sli htly modilied so as to adapt it to be secured to the end sill or other end structure of the car at a point to one side of the train pipe, as best shown by Figure 3. Furthermore, the holder A is adapted for the securing of the train pipe'116 only. The holder is open at the bottom as indicated at 40 to allow the pipe to be inserted within the opening from underneath, the pipe being wedged against the bearing faces 118118 by a similar key 121, to that shown in Figures 1 and 2. I11 the arrangement of Figures 3 and 4, I have also shown the backinglug 128 for the hexagonal nut 126, said lug 128 being bendable and ad justable vertically as in the case of the lug 28. In the arrangement shown in Figures 5.

and 6, the pipe holder A is adapted to be secured to a needle beam ll or other cross beam of the car beneath which the train pipe 216 and signal pipe 217 are disposed. In the holder A a main pipe-receiving opening 215 is provided with the greatest dimension there of extending horizontally and formed at one end thereof with bearings 218 for the train pipe and at the other end thereof with bearings 219 for the signal pipe. The vertical dimension of the opening 215, at the center, is great enough to permit the holder or anchor to he slipped over the train pipe and any T couplings thereon.

In the holder of Figures 5 and 6, the slots for the key 221 are arranged in vertical alinement as indicated at 220220. \Vith the arrangement shown in Figure 5, it will be observed that the same three-point bearing is obtained as in the case of the structure illustrated in Figures 1 and 2 and heretofore described.

I have herein shown and described what I now consider the preferred manner of carrying out the invention but the same is merely illustrative and I contemplate such changes and modifications as come within the scope of the claims appended hereto.

I claim:

1. A device of the character described, having a. main pipe receiving opening therethrough, said opening being formed at its ends with bearing surfaces for two pipes, said device having aligned slots arranged transversely to said main opening, each of said slots being of tapering form and adapted to accommodate a wedge key therethrough, the

taper of said slots being in opposite direcous and adapted to surround the pipes, said 1) holder having means for the reception of a wedge key; and a wedge key, independent of said support and holders, and mounted in said wedge receiving means and positioned to pass between said pipes, the opposite side edges H of said wedge key being positioned to engage the pipes to wedge the same in opposite directio'ns and clamp the same against adjacent portions of the wall defining said opening.

In witness that I claim the foregoing I have hereunto subscribed my name this 8th day of March, 1922. p

RICHARD IV. BURNETT.
