CLEON M. HANNAFORD, OF RICHMOND, VIRGINIA.

HOLDER FOR ANGLE COCKS.

Application led September 18, A1922. Serial No. 589,374.

To all whom z'zf may concern:

' Be it known that I, CLEON M. HANNA- rom), a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented a certain new and useful Improvement in Holders for Angle Cocks, of which the following is a full, clear, and exact description.

The object of this invention is to roduce an angle cock with a self-contained iolding member by which it may Abe held in position -on a car ink connection with the trainv pipe; the invention beingl applicable also to other valves and pipe connections.

The invention consists in an angle cock provided with a continuation of its shell or body and in one piece 'therewith and extending rearwardly from its hex, that is to say, its polygonal end7 and adapted for cooperation with a supporting member extending from the car and a suitable bolt or bolts for rigidly connecting the supporting member, angle cock and train pipe, as I will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is va perspective view of a portion of an angle cock having an extended rear end. Fig. 2 is a side elevation of the cock in position on the end of a car. Fig. 3 is a cross section taken on the line 3--3 of Fig. 2. Fig. 4 is a partial sectional elevation showing the angle cock of this invention used in connection with a bushing whereby it may be applied to a train pipe of smaller diameter than the internal diameter of the angle cock extension. Fig.- 5 is a fragmentary side elevation and Fig. 6 is a cross section illustrating a inodification. Fig. 7 :is a fragmentary side elevation and Fig. 8 a cross section illustrating. another modification.

The angle cock'body l and the various parts of the angle cock may be as usual, excepting that the body is provided with la rearward extension 2 back of the hex 3. As shown in Fig. l, this extension 2 is internallyscrewthreaded so as to engage the screwthread on the train pipe 4:, and itis provided with a slabbe'd-offv or flat top 5 to cooperate with the complemental end 6 of the horizontal portion 7 of the supporting bracket 8, which latter may be riveted to the end sill 9 of the car. Any other support for the angle cock and train pipe may be used, although this L-shaped bracket is the preferred construction. On opposite sides of the extension 2 are grooves l0, and these grooves are designed to receive a U- bolt or other fastening member 11, which straddles the extension or otherwise engages it, and passes up through the holes in the portion 6 of the support and is there secured by means of nuts or equivalent fastenings 12.

f As will `be observed, the train pipe is in engagement with the horizontal portion of the supporting bracket and this engagement is rendered secure by any suitable means, such as U-bolts 13, while the slabbed-off or flat portion 5 is in engagement with the portion G of the supporting bracket, so that the train pipe and the angle cock may fit flush with this bracket.

The slabbed off or fiat portion 5 by virtue of its engagement with the supporting bracket prevents the accidental turning of the angle cock, thatis to say, the accidental rotation of the angle cock on the train pipe as an axis, while the engagement of the bolts 1l with the grooves 10 prevents the longitudinal escape or accidental detachment of the angle cock.

As shown in Figs. l, 2 and 3, the equipment is that of a freight car, but as illustrated in Fig. 4, the same angle cock, bolts and brackets may be used on the train pipe of a passenger car by using the bushing 14 betweenther trainpipe and the extension.

. As shown in Figs. 1 and 2, the extension 2 may be a straight extension, but as shown in Fig. 4, the extension may end in a flange l5. This flange in its relation to the U- bolt or other fastening medium, will prevent the angle cock from being lost in case the train pipe comes loose or its threads are stripped.

Y The distance from the face of the hex to the rear flange permits slight adjustments to suit the supporting bracket and to provide for slight variations in train pipe lengths.

The supporting bracket in the preferred construction is a steel plate'bent to suit the conditions at the end of the car, but obviously when these conditions are substantially uniform, yit. is possible to make the supporting bracket as a casting.

As shown in Figs.` 5 and 6, instead of making a cylindrical extension, the extension may be semi-cylindrical and located at the bottom, as shown at 16. In this case the outer faces of the extension may be angular as shown in Fig. 6 and the sides of the extension will be made with grooves or otherwise, for cooperat-ion with the fastening bolt.

As shown in Figs. 7 and 8, the extension 17 may be semi-cylindrical and project from the upper portion of the angle cock body, and in this case, the top of the extension will be slabbed olf or made flat, as shown in Fig. 8, to cooperate with the portion 6 of the supporting bracket, and the sides of the extension may be grooved or otherwise formed to cooperate with the U-bolt or other fastenmfr.

In both of these modifications, it is preferred to use the flanges 18 and 19.

In all of the forms illustrated the rearward extension is in one piece with the shell or body of the anglev cock.

When the bolts 11 and 13 have been removed from operating position andthe train 'pipe is hanging free, the angle cock may be unscrewed, removed or applied, without removing the supporting bracket 8 from the car. f

In order to prevent air hose failure caused by the air hose fouling or rubbing against the coupler when the cars are going around a sharp curve, the American Railroad Association after careful and thorough investigation Iadopted a standard location for the angle cock relative to the coupler and car and required that the angle cock should be arranged at an angle of 300.

As at present designed the angle cock body isA provided with a hexagonal portion, commonly known as the hex, which serves as means for screwing the angle cock on the train pipe and also serves as a means to cooperate with various forms of angle cock holders which serve the purpose of maintainingthe-angle `cock at its 30 arrangement, as wel] as supporting it against dislocation lengthwise or loss if accidently detached from the train pipe. These angle cock hold ers are of a variety of constructions, usually in two or more pieces and made as castings, and they engage the hex of the angle cock and are fastened to some part of the car so as to hold the angle cock in proper position.

Inasmuch as the angle cock is located out and away from the car body, there is considerable strain placed upon the angle cock holder and it is soon broken and the angle cock pulled loose from the train pipe, thereby causing air brake failure, and the cocks themselves are lost.

With the angle cock made with a rearward extension beyond its hex, it is unnecessary to use any of the common forms of angle cock holders and it is sufficient to supply a supporting bracket, such as 8, to which the angle cock is bolted through its rear extension in such way as to be held at the proper angle and at such location as to avoid fouling or rubbing against the coupler. At practically all railway repair points, open hearth steel plates are carried in stock, and in case the bracket installation should become damaged, the damage may be quickly repaired by lliending a steel plate to suit the repair wor r.

It will therefore be seen that no special angle cock holder castings need be carried in stock.

As will be seen the invention is susceptible of various modifications and alterations and these are believed to be within the spirit of the invention and the scope of the claims following.

lVhat I claim is 1- l. An angle cock, having a shell or body provided with a rearward extension beyond its hex and in one piece with the shell or body and adapted to engage a train pipe and be received by the fastening element which holds the angle cock to its support.

2. An angle cock, having a shell or body provided with a rearward extension in one piece therewith and provided with a flat surface to engage a support and lateral depressions to be engaged by a fastening medium to fasten the angle cock to the support.

3. An angle cock having a shell or body provided with a cylindrical rearward extension in one piece therewith and having a flat surface to engage a support and lateral depressions to be engaged by a fastening medium to fasten the angle cock to the support.

t. An angle cock, having a shell or body provided with a rearward extension made in one piece therewith and constructed with a slabbed off upper portion and laterally arranged grooves. y

5. An angle cock, having a shell or body provided with an extension rearward of its hex and made in one piece with its shell or body and adapted to be engaged with a train pipe and a supporting bracket, said extension provided with a terminal flange adapted to cooperate with a fastening medium for uniting the extension, train pipe and supporting bracket.

In testimony whereof I have hereunto set my hand this 21st day of August, A. D. 1922.
