RETAINING-VALVE monon- Application filed June 10, 1925. Serial No. 36,202.
. taining valve to the end wall of a car by taining valve inside of the car, thus necessimeans of lag screws and bolts in the wooden type of car and by rivets in the steeltype of car, but the lag screws due to the weaving of the car in service far quickly become loosened, as do also the bolts and rivets, thus loosening the anchorage of the retaining valve to such an extent that its pipe leading from the air brake system is free to swing like a pendulum thereby reducing the "efficiency of the air brake system.
In many instances when the retaining valve becomes loose it is necessary to unload a car for the purpose of permitting a workman to get at the bolts and rivets of the retating in many instances the breaking of the car seal while the car is in transit thereby increasing liability of the railroad for damage and stolen goods, besides which the unloading and loading of a car for this repair is quite an expense.
The object of my invention is to provide an anchor for a retaining valve which is of- -such construction that 1tmay. be secured firmly to. a car and permit of the attachment 0 and detachment of the retaining valve to such anchor without necessitating the re-: moval of the load from the car, thereby reducing the expense of repairs of such valves to a minimum and eliminating the-necessity of removing the loadfrom thecar and breaking the seal of the car while the car is in ,transit.

In the drawings:
Figure 1 is a fragmentary end 'view of a my invention mou nted.
railroad car with thereon. Figure 2 is a front elevation of my improved valve anchor.
Figure 3 is a side-elevation of the same.
. Figure 4 is a front elevation ofanother I embodiment of my invention.
Figure 5 1s a side elevation of the same.
Figure 6 is a front elevation of another from the air brake system of the car underneath the car to a point near the top of the car on the-upper end of which is secured the retaining valve 3 in convenient position to be readily accessible for operation from the the top of the car, or from the usual ladder 4.
My improved anchor may be of varied construction and 'I have selected for the purposes of illustrating my invention, 'in the many views of the drawings, a type of construct-ion that, in casting, will not require a core other than, a green sand core, which will not require a core box and is made in'the mold. Some of the constructions which .I show may require a separate core in the mold; however, the molding process does not form a part of my invention, my invention residing in the anchor irrespective of its method of molding.
My improved anchor comprises an attaching plate 5 which is formed with a rivet or bolt openings 6 around which I form bosses 7. A shelf 8 integral with the plate 5' extends downwardly and forwardly from the bottom of. the plate 5 at ,the desired angle from thebottom of which shelf an apron 9 depends, theapron' and attaching plate5 be-, ing parallel with the apron being slightly in advance of the attaching plate as more clearly shown in the side elevation, of the anchor. The apron 9 is provided with elongated slots 10 and bosses 11- extending around said slots on the outer face-of the apron thereby rigidifying' the apron.; Ribs 12, 13 and 14 are caston the rear face of the anchor and extend from the bottom edge of the attaching plate 5 to the lower edge of theapron 9, the ribs extending vertically and being integral with the plate '5,v shelf 8 and apron 9-a-s clearly shown in the drawfrom the drawings, are relatively positioned with reference to the slots 10 in the apron so that they may function as 'a stop to limit rotation of the bolt by reason of the side edge of the head 16 of the bolt coming in contact with the flanges 12 and 14, as illustrated in the drawings.-
Theshelf 8 is provided with a bolt opening 17 of such diameter as to permit of the ready insertion of the head 16 of the bolt therethrough so that the bolt may pass through said opening 17 and permit the head 16 to slide downwardly back of the rear face of the apron 9 with one side edge of the head 16 in comparatively close relation to the ribs 12 and 14. In addition to these ribs functioning as stops to prevent the turning of the bolts they also rigidify and strengthen the casting as will be readily understood.
My improved anchor is secured to the car wall by bolts or rivets passed through the openings 6 in the attaching plate, and when the anchor is attached to the car the apron 9 by reason of the shelf 8 is spaced from the face of the car wall. The heads or bolts 15 are then passed through the opening 17 in the shelf and permitted to drop down back of the apron 9, the body of the bolt being positioned in the slots 10. The retaining valve is provided with suitable brackets or lugs 18 having bolt openings, therethrough, and through which the bolts 15 pass thereby holding the valve to the anchor. The nuts on bolts 15 are then manipulated until the valve is securely and firmly attached to the anchor. In the manipulation of the nuts on the bolts 15 it is not necessary to place a wrench on the head 16 of the bolt to keep the bolt from revolving, inasmuch as one side edge of the head 16 of the bolt contacts with the rib 12 or 14 and is thereby prevented from turning. v
In Figure '4 I have shown another embodiment of my invention which is in material respects of the same construction as above described, the only substantial differ "'ence residing in the shelf 19 being at substantially right angles to. the attached plate and the apron. Inthis figure I have shown the ribs or flanges 23 as extending in full width from top to bottom of the apron as distinguished from the tapering flanges 12, 13 and 14 in the other construction.
In Figure 6 I have shown another embodiment of vmy invention in which the apron 20 extends upwardly from the shelf 21 whereby elongated slots 22 open in the upper edge of the apron 20. -1
In many instances it has been found that under service conditions the screwthreads on the upper end of the retaining valve break, or the pipe breaks at the point where it enters the-retaining valve; Under such condltionsheretofore it was necessary to replace the retainer valve pipe of the full.
.tainer pipe. By this my invention,'the retainer pipe, can be rethreaded and replaced in the retaining valve and this rethreading can be done a number of times within the limits of the length of the bolt ways or slots.
It is obviously more economical to rethread the retainer valve pipe, already on the car, than to replace a new pipe.
I- am aware that other changes may be made in the details of construction Without departing from thescope of the appended claims.
