RETAINING VALVE BRACKET Filed Sept. 8, 1925 Patented Use. 10, 1929 llhlll'Efl STATES VICTOR H. HARBERT, OF SPRINGFIELD, ILLINOIS RETAINING-VALVE BRACKET Application filed September Retaining valves are applied to cars to i make the movei'nent of a train of cars safe,

and to cons rve the supply of air, and this valve when and in good working order a does not allow all of the air to escape :trom

the brake cylinder, but retains a certain amount or" pressure therein suliicient to hold the brakes in a set position, while the air is being replenished in the train line. i l hen the air pressure in the line is increased or replenished, if the retaining valve is in an inoperative condition, the triple valve will automatically assume a released position allowing the train to gain momentum and run out of control. lit 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 invention was to bolt the retaining valve through the our end wall, but this practice has been found objectionable in that the bolt holes in the car Wall gradually increase in diameter, d to to the service movements of the car, whereby the bolts become lose, thus leaving the valve and its pipe free to swing, thereby reducing the elliciency of the valve.

ll hen the retaining valve becomes detective. it is necessary to remove the bolts from the inside of the car whether it be a house 30 car or open ear, and it the car happens to be loaded, the load must be removed.

The object of my invention is to provide an anchor -for a retaining valve so mounted on the ear and oil such construction that the retaining valve may be detached from and applied to the anchor Without removing the load from the ear, thereby reducing the expense of repairs to a minimum, and eliminating the possibility of damage and loss of the contents of the car.

In the drawings:

' l is a front elevation oi my anchor s, 1925'. Serial No. 55,198.

Figure 3 is a front elevation of my im proved anchor or bracket.

Fig. is a sectional view taken on the line l-d of Figure Fig. 5 a top plan view of Figure 3.

The reference numeral 1 pipe, tori'ning part of the air brake system of the car, to the upper end of which is secured the retaining valve 2, which is provided with the lugs or ears 3 having bolt or rivet openings thereihrough.

My improved anchor or bracket comprises a base plate 4r having at its upper edge a spacing member or shell 5 extending forwardly and at right angles to said base. An apron 6 depends from the outer edge of the shelf and is spaced from and parallel to the base. but does not extend to the bottom edge of the base, as more clearly seen in Figures 2 and t. lhrough the base and below the lower edge of the apron are bolt or rivet holes 7' through which belts or rivets pass to secure the anchor to the car wall.

In the shelf 5, 1. term rectangular openings 8 through which the head 9 of bolts l0 ma pass, and there being a slot ll in the shelf 5 communicating with these openings 8. to permit the oi? the body of the bolts into the elognated slots 12 formed in the apron 6, whereby the bolt heads 9 may pass down between the apron 6 and base as clearly shown in Fig. 2.

The anchor is secured firmly to the car Wall. In attaching the retaining valve to the anchor the bolts may be positioned loosely in the slots 12 and when the valve is in proper position, the bolts are aligned With the holes in the ears 3 and the valve then pushed onto the bolts and the nuts 13 screwed tightly on i the bolts, firmly securing the valve to the anchor. It will be noted that all operations necessary to attach or remove the valve from the car are performed outside of the car.

In the first installation, the bolts 10 are firmly secured near the top of the slots 12 so 1 L o designates the air that, in the event of any shortening of the pipe 1, due to breakage, re-threading, etc., of the pipe, the bolts 10 may be lowered in the slots to take care of any variations of length in the pipe, within reasonable limits, without disturbing the original position of the anchor- What I claim is 1. A retaining valve anchor comprising a base, an apron extending downwardly from the top of and spaced from and parallel with and terminating short of said base, elongated slots in said apron opening at the top of said base, elongated slots in said apron, terminating in enlarged openings in said shelf.

a 4. A retaining Valve anchor, comprlslng a base adapted to be secured to a support, a

spacing member extending forwardly from the top of said base, and a plate depending from said spacing member and spaced from the base, said plate being adapted to support a retainingvalve.

5. A retaining valve anchor, comprising a base'adapted to be secured to a support, a

spacing member extending forwardly from the top of-the base, and a retaining valve supporting plate depending from said spacing member and spaced from the base and terminating short of'the bottom edge of said base.

6. A retaining valve anchor, comprising a base adapted to be secured to a support, a spacing member extending forwardly from the top of said base, a retaining valve supporting plate depending from said spacing member and spaced from the base and bolt openings to receive bolts whereby the retaining valve is secured to said plate.

7 A retaining valve bracket comprising a base portion adapted to be secured to a support, a spacing portion extending forwardly in the other side of the plate for receiving the valve anchor bolts.

9. A retaining valve bracket comprising an. inverted U-shaped member, one leg of the member being extended beyond the plane of the perimeter of the other leg and having apertures to receive bolts for securing the bracket to a car wall, while the other leg of the member is apertured to receive valve anchor bolts.

In testimony whereof I affix my signature.

VICTOR H. HARBERT.
