EDWARD W. GOODWIN, OF BENSONI-IURST, NEW YORK, ASSIGNOR T0 GOODWIN CAR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF ILLINOIS.

VALVE-REPLACING APPARATUS.

To all whom it may concern:

Be it known that I, EDWARD W. GOODWIN, a resident of Bensonhurst, in the borough of Brooklyn, city and State of New York, and whose post-otlice address is No. 17 Battery Place, borough of Manhattan, New York city, State of New York, have invented certain new and useful Improvements in Valve- Replacing Apparatus, of which the following, taken in conjunction with the accompanying drawings, is a full, clear, and concise specification.

My invention relates to valve-replacing apparatus for railway dumping cars, and more particularly for dumping cars of the well-known Goodwin type.

The invention consists in the combination with such and similar cars, of valvereplac ing cylinders having pistons adapted for connection with the dumping valves thereof, and in the relative arrangement and combination of the several parts and accessories as will be hereinafter fully described and more particularly pointed out in the accompanying claims.

In the drawings which form a part hereof, Figure l is a vertical transverse section of a Goodwin car employing my invention, certain unessential and usual parts of the car construction being omitted for clearness; Fig. 2 is a top plan view of the car of Fig. l; Fig. 3 is a side elevation of one corner of the car of Figs. l and 2, with the end of the side girder broken away to expose the hinge block and the cylinder operating connections; Fig. l is a cross-section through the housing taken on line IV, IV of Fig. l and in the direction of t-he arrows.

Referring first to the general construction of the car illustrated in the above figures, the cargo-receptacle is formed by the end and cross bulkheads by retaining walls L, L, by the inclined side-walls or floors D D, by the gravity dumping valves G and by the center detent valves A. The outermost of these valves are double hinged, by means of pivoted hinge-links B, to the hinge-blocks B which latter are securely fastened in the angle between the inclined side-floors D and the vertical side girders H. The detent valves A hinge on the central shaft J, and when closed, support the free inboard ends of the valves G as shown in the drawing. They are in turn supported in this position by strut brackets A A which rest upon the Specification of Letters Patent.

detents C C of the rock-shafts C C', in such manner that by appropriately rocking either or both of the said shafts, all the valves may be released and the cargo discharged. The weight of the cargo receptacle is carried by the two center sills S S, through the bulkheads and holsters in the usual manner.

The apparatus for replacing the valves when they have been opened as above described, comprises one or more cylinders and pistons each confined within a chamber or housing which is formed as a structural part of the cargo receptacle. The controlling or operating means for the apparatus are confined wit-hin the angular space between the inclined side-floors and the girders, outside of the receptacle and in a position in which thev may be manipulated from either end of the car. In the form of my invention herein illustrated, t-he housing is formed by a cross-member l, spanning the cargo receptacle adjacent and parallel to one of the bulkheads and joined to that bulkhead by means of a channel-beam 2, which is riveted, by each of its down-turned flanges, respectively to the tops of the bulkhead and crossmember, thus forming a roof for the housing as shown in Fig. 4:. The bottom of the housing is open in order to allow access to the cylinder and pist-on, as well as to provide an eXit for the valve chain. At one end the housing is in open communication, with the exterior angular space referred to, through an opening or past the end of the side-floor D. This opening is shown in Fig. 3 as consisting of a hole cut or punched near the end of the side-floor D, and occupied by the pipe 17 and link 20.

The ends of cross-member l are rigidly joined to the side-oors D and side-girders H by means of the flat angle-plates 3 which are securely riveted to the crossmember and fastened to the side-girder H and also to inclined side-walls D, by means of the bent angle-bars 1l, the said angleeplate 3 being of greater depth than the cross-member, and of triangular shape as shown, so that it forms a substantial bracket support for the ends of the same and likewise serves as a guard plate to obstruct escape of cargo through the above mentioned opening which, as stated, leads from the inside the cargo receptacle to the outside thereof.

The cylinder 5 is securely fastened within the housing adjacent the opening and its piston G is connected with a flexible member or chain 7 which is trained first over the sheave S at the opposite end of the housing and the-n over the central sheave 9, the end of the chain hanging over the sheave being supplied with a hook or equivalent means adapted for attaching it to one of the other of the valves, z'. e., the valve on either side of the center detent valves A. The sheaves above mentioned are journaled upon arbors carried by the sides of the housing, and the central sheave has its arbor specially supported by means of two vertical interior straps 10 which may project somewhat below the cross-member, being securely riveted at their tops to the channel-beam Q., the securing rivets extending also through the cross-member 1 and end bulkhead, respectively. As thus arranged the piston-rod of the cylinder may have a stroke equivalent to the distance through which the valves have to be moved in order to be closed, and may at the same time be conlined to the space afforded by the wall of the cargo receptacle. A supporting roller 25 is also used between the two sheaves for preventing the upper stretch of chain from interfering with the lower stretch. The cylinder is supplied with compressed air or other fluid pressure from the reservoir 11, located between the center sills S S, through the supply pipe 12 and a threeway cock 13, the latter being of ordinary construction and provided with the usual lever or handle lei by means of which air may be admitted behind the piston, through branch pipe 15, or in front of the piston through branch pipe 1G, to thereby project or retract the piston-rod. The reservoir 11 is supplied with compressed air from the air-brake train-line, not shown, in any convenient manner.

In the form of my invention which I have illust-rated in the present drawings, there is one cylinder, as above described, for each end of the valve to be closed, the housings for each cylinder being substantially identical, and the supply pipe 1Q extends longitudinally into the angular space beneath and along the inclined side-floor D and supplies compressed air to each of the said cylinders or to as many of them as may be installed upon the car, the connections being taken oftl by means of branch-pipes such as shown at 17 (Fig. The part of the pipe 12 which is confined within the angular vspace is supported in openings in the webs of the hinge-blocks B above referred to.

The desired operation of the several pistons is accomplished by a longitudinal rocksliaft 18, likewise journaled within or upon the hinge-blocks B', and provided with crank-arms 19 which are connected by the links 20 with the levers 14- of the three-way cocks. The end of the shaft is accessible at the end of the car as shown in Fig. 2, so that the operator may manipulate all of the cocks simultaneously from the car platform and produce simultaneous operation of both or all of the cylinders, this being an important feature of my invention. Thus, by turning the shaft 19 in one direction, compressed air may be admitted through cock 13 and pipe 15, to force the piston outwardly so that the valve chain may be hooked to the open valve. Turning the rock-shaft 19 in the opposite direction admits compressed air through pipe 1G and draws the piston back, which replaces or closes the side dumping valve G iirobvious manner. The arrangement of the replacing apparatus within the housing as shown, and at the ripper margin of the cargo receptacle, adapts it for occupying the least possible space, and the arrangement of the housing with its detlecting and supporting angleplates 3 permits the operation to be carried on from the exterior and at the same time prevents leakage of the cargo. The chains also hang directly from their pistons within the car and can be inspected and greased without difliculty, and various other advantages are secured which will be manifest to those skilled in the art.

Having described my invention, what I claim and desire to secure .by United States Letters Patent is:
