JOHN PLAYER, OF DUNKIRK, NEW YORK, ASSIGNOR TO AMERICAN LOCOMO- TIVE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

REVERSE-LEVER.

SEECIFICATION forming part of Letters Patent No. 696,482, dated April 1, 1902.

Application filed July 23,1901- To all whom, it may concern:

Be it known that I, JOHN PLAYER, of Dnnkirk, in the county of Chautauqua and State of New York, have invented a certain new and useful Improvement in Reverse-Levers,

of which improvement the following is a specification. m

My invention relates to reverse-levers employed on locomotive-engines of the wide or widened fire-box type; and its object is to provide a reverse-lever which can be located and operated in rear of the fire-box and which shall be of simpler and less expensive coustruction than appliances heretofore used for the same purpose.

To this end my invention, generally stated, consists in the combination of an integral body which is provided with a bearing-pin socket at its lower end, areach-rod-pin socket located at one side of its upper end and projectiug outwardly beyond the bearing-pin socket, and a lever-arm fixed to the upper end of the body on the side thereof opposite the reach-rod-pin socket.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a diagrammatic side view of a locomotiveeugine, illustrating an application of my in- 0 vention; Fig. 2, a similar end view of the same; Fig. 3, a transverse section at the line a a of Fig. 1; Fig. 4, a rear View, on an enlarged scale, of the appliance complete; Fig.

5, a similar View, on a further-enlarged scale, 5 of the reverse-lever body as seen from the rear; Figs. 6 and 7, views in elevation of the same as seen from the inner and the outer side, respectively; and Fig. 8 a horizontal section at the line b b of Fig. 5.

My invention is herein exemplified as applied in connection with a locomotive-engine of recent design and construction which is of the high-speed, heavy-draft, wide-fire-box type. The locomotive is supported on three 5 pairs of driving-wheels l of comparatively large diameter, a pair of leading-wheels 2, and a pair of trailing wheels 3. The boiler 4 is provided with a wide fire-box 5, by which is meant a fire-box which is of greater width than the distance between the inside faces of the driving-wheels, and the cab 5 is lo- Serial No. 69,375. (No model.)

cated above the fire-box and extended in rear thereof in order to enable the engineer and fireman to be both stationed behind the firebox and to perform their duties in the same inclosure. The lifting-shaft or tumblingshaft 6, by which the valve-links 7 are raised and lowered to effect the reversal of the direction of movement of the engine and the variation of the point of cut-off as from time to time required, is journaled in hearings on the frames 8 between the forward and middle pairs of driving-wheels and is actuated by a reach-rod 9, the forward end of which is coupled to a tumbling-shaft lever 10 and the rear end to the reverse-lever. With a cab located as above described it is desirable that the full traverse of the reverse-lever should be made in rear of the fire-box in order to facilitate the operations performed by the engineer, and to enable this to be done and the connection of the reverse-lever with the tumbling-shaft to be properly effected a special construction of reverse-lever becomes indispensable in wide-firebox engines having a cab which extends behind the fire-box. My invention provides an appliance which has been shown in practice to be satisfactorily adapted to the structural and operative conditions for which it is designed and which is of simple, durable, and inexpensive construction.

In the specific embodiment of my inven tion which is herein exemplified the complete reverse-lever is composed of an integral body 11 and a lever-arn1 12, fixed thereto. The body 11 is preferably a steel casting in the form of a plate, the upper end of which is outwardly or laterally extended at one side relatively to its lower end and which may have one or more openings 14 cored in it to reduce its weight. A bearing-pin socket 15 for the reception of a fixed bearingpin 16, upon which the reverse-lever is fitted to traverse, is formed on the lower end of the body 11, and strengthening-flanges 17 are preferably cast upon its top and its inner and outer sides. The lever arm 12 is preferably, as shown, detachably connected to the body 11, and to this end the body 11 is upwardly extended at its top, on its inner side, such extension forming a lever-arm seat or face 18, which is provided with vertical side flanges 19 and is perforated with bolt-holes 20 to receive connecting-bolts 13. The outer side of the body is also upwardly extended, and a reach-rod-pin socket 21 to receive the pin by which the reach-rod is coupled to the reverse-lever is formed in the outer upper extension. The lever-arm 12 is fitted on the lever arm seat 18 between and abutting against the lateral flanges 19 thereof and is rigidly secured to the body either by the connecting-bolts 13, as shown, or in any other suitable known manner, as by being screwed or keyed thereto. The upper end of the leverarm 12 is formed into a handle of suitable form and dimensions to be conveniently grasped by the engineer, and it is provided with a spring-latch of any known and preferred construction, which is adapted to engage the notches of the usual fixed segment and which does not form part of my present invention.

While a construction in which the leverarm is formed separately from the body and is fixed detachably thereto, as in the instance shown, is believed to be the preferable one, the lever-arm may, if desired, be cast in one piece without departure from the spirit of my invention.

The bearing-pin 16 fits truly in the bearingpin socket 15 of the body and is secured to the upper end of a bracket or standard 22, the lower end of which is secured to one of the frame members 8 of the engine or to any other suitable foundation,the pin 16 thus constituting a fixed bearing on which the reverselever is swung forwardly and backwardly by the engineer to move the tumbling-shaft in either direction, as desired.

It will be apparent to those familiar with locomotive-engine design and construction 7 that a reverse-lever constructed substantially as above described presents the advantages of being less expensive thanone which is formed of several connected forged members, of being amply strong and rigid, with a minimum of weight, and of the capacity of ready adaptation in engines of all of the various special designs of the wide or widened firebox types in which a cab at the rear end is employed.

I claim as my invention and desire to secure by Letters Patent- 1. In a reverse-lever, the combination of an I integral body, which is provided with a bearing-pin socket at its lower end, a reach-rodpin socket located at one side of its upper end and projecting outwardly beyond the bearingpin socket, and a lever-arm fixed to the upper end of the body, on the side thereof opposite the reach-rod-pin socket.

2. In a reverse-lever, the combination of an integral body, which is provided with a bearing-pin socket at its lower end, a reach-rodpin socket located at one side of its upper end and projecting outwardly beyond the bearing-pin socket, and a lever-arm seat at the opposite side of its upper end, and a lever-arm fitting the lever-arm seat, and secured thereat to the body.

3. In a reverse-lever, the combination of an integral body, which is provided with a bearing-pin socket at its lower end, a reach-rodpin socket located at one side of its upper end and projecting outwardly beyond the bearingpin socket, and a lever-arm seat at the opposite side of its upper end, and a lever-arm fitting the lever-arm seat and secured detachably to the body.

4. In a reverse-lever, the combination of an integral body, which is provided with a bearing-pin socket at its lower end, a reach-rodpin socket located at one side of its upper end and projecting outwardly beyondthe bearingpin socket, and a laterally-flanged lever-arm seat at the-opposite side of its upper end, and a lever-arm fitting on the lever-arm seat and abutting on the lateral flanges thereof and secured detachably to the body.

5; In a reverse-lever, the combination of an integral cast-metal body, which is provided with a bearing-pin socket at its lower end, a reach-rod-pin socket located at one side of its upper end and projecting outwardly beyond the bearing-pin socket, a lever-arm seat at the opposite side of its upper end, and strengthening edge flanges connecting its sockets one with the other and with the leverarm seat, and a lever-arm fixed to the body at the lever-arm seat.

6. In a reverse-lever, the combination of an integral plate reverse-lever body, which is provided with a bearing-pin socket at its lower end, a reach-rod-pin socket located at one side of its upper end and projecting outwardl y beyond the bearing-pin socket, a bearing-pin secured to a fixed support and fitting the bearing-pin socket, and a lever-arm fixed to the upper end of the body on the side thereof opposite the bearing-pin socket.
