Application filed September 16, 1925. SerialNo 56,717. 1

Retaining valves are applied to cars to make the'movement of a train of cars safe, and to, conserve the supply ofv air, and this valve when set and inv good working order, does not allow all of the air to escape from the brake cylinder, but retains a certain amount of pressure therein suflicient to hold the brakes in a set position, while the. air. is being replenished in the train line. lV hen the air pressure in the lineisfincreased' or replenished if the retaining valve is 'inan inoperative condition, the triple valve will automatically assume a released position allowing the train to gain momentum, and

run out of control. It is, therefore of the utmost importance that the retaining valve be in good'working order at all times.

The practice in vogue :prior to my inven tion was to bolt'the retaining valve through the car end wall, but this practice has been found objectionable in that the bolt holes i in the car wall gradually increase in diamebe loaded, the load must be removed The object of my invention is to provide an anchor for a retaining valve so mounted on the car and of such construction that theretaining valve may be detached from and applied to the anchor without removing the load from the car, thereby reducing the expense of repairs to a minimum, and elimi nating the possibility of damage and. loss of the contents of the car.

The referencenumeral' '13 designates aretaining valve of standard construction-provided with side'ears 14 and an operating handlelf), theears 14 being provided with suitable bolt openings. Y 1. I v As shown in the drawings, my. anchor or bracket is susceptible of many modifications or embodiments without departing from the spirit of my invention.

In the embodiment shown'in Figures 1 to a the anchor comprises a main body plate 16 having bolt or rivet openings 17 near its upper edge through which bolts or rivets pass to secure the anchoror bracket to the car-in a suitable position, at the lower end of the body plate I provide a rebent portion which COIISlSlJS' of. a. forwardly extending spacing member 18 from the forward edge of which a flange 19 extends; upwardly and I substantially parallelwith the, body plate 16. This flange'l9, is'providedy, with elongated s-lots 20, spaced to coincide with. the bolt openings in; the ears] 1% oflthewaive,

said slots being open atthe upperedge of the flange 19 as shown. y V 7 If desired, lugs 21 maybe formed on the elongated slots 20 to function as rests supports for the head of the bolts supportlng the-boltsin an adJuSted position before the nuts 24 are tightened, Again,

these lugs also function too as abutments to prevent the bolt turning while the nut is being screwed on and oti'the bolt as' will be understood. j H I a H In Figures 5 and 6 tl'1econst-ruction is substantially the same as shown in Figures-i to 4 the difierence being that the flange 25.,

extends to the top "edge of the body plate 26. as. clearly shownin Figure 6, and the body plate 1s provided with cars 27 extend ing from its ends, which ears are provided with bolt openings 28 through which bolts pass to secure the anchor. to the cars. The flange '25is provided; with elongated 29 corresponding with the slots 20 of ure 3. ii

In Figures 7 to 9 the construction of the bracket or a'nchor is like that-shown in Figslots ures 1 to 1, the difii'erence residing in providing the edges or, side walls of the elongated slots with pro ect1ons 30-and depressions 31, the progections 30 on one side of the slot being oppositethe depression 31 on the other side of theisame slot thereby torming a substantially sinuous slot in the flange 32 of the body plate 33v whereby the bolt will be held inthe depressions 31 in pre-v "l'iininarrf ad'usted osit-ion;

I-nFigures 10 to 12 the construction is practically the same as shown in Figures 7 toll, the only dilterence being that the projections 3a and the depressions 35 are formed-on curves as "distinguished from the angular -i'ormation shown in Figure 7. In

7 Fi ures 10 to 12, 36 designates the body pla teland 37 the flange.

In. use my improvedbracket or anchor is bolted or riveted to the wall of the car 'permanently in the desired positions, the

rivets passing through the openings in the body plate.

7 Now in mounting the valve on my anchor the bolts 22 may be loosely mounted in the holes injthe ears 14 of the valve or they may be loosely placed in the elongated slots with.

a the heads of the bolts between the body plate and the flange. In the first application the bolts 22 are positioned near the top oi. the elongated slots so that if for any reason it is necessary to shorten the air pipe 37 the bolts may be placed ina lower posit-ion inthe slots as'will be understood.

When the valve and bolts 22 are in proper position relative to the anchor the nuts 24 are tightenedfthereby securing the valve to V the anchor firmly.

It will be seen th'atthe valve may be ap plied to and detached from the car with out entering the car.

What I claim is:

1. A bracket for a retaining valve comprising a fiat plate having a return Lip-- owardly extending spaced flange at its'lower end provided with elongated slots open. at

the upper edge of the flange, said plate having bolt openings through-it.

2. A bracket for V retaining valves comprising a flat plate having bolt openings,a

spacing member extending forwardly from the lower edge portion of theplate, a flange extending upwardly from said spacing 1nen1- her and substantially parallel withthe said plate, elongated slots in saidflan e -open at'th'e top edge of the flange ant. means on the flange to support a bolt in vertically adjusted position in said slots.

3. A bracket for retaining valves cont.

prising a flat plate having bolt openings, spacing member extending forwardlytrom the lower edge portion of the plate, a flange extending upwardly from said vioron nanis'nnr;

spacing spacing 1 member and substantially parallel with the
