BENJAMIN F. CLARK AND CHARLES OOR-NWELL, OF PHILADELPHIA, PA.

ADJUSTABLE DRAW-BAR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 248,291, dated October 18, 1881,- Application filed July 29, 1881. (No model.)

To all whom it may concern Be it known that we, BENJAMIN F. CLARK and. CHARLES OORNWELL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Draw-Bars for Street-Railway Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which-- Figure 1 is aplanofa portion of the truck of a street-car, partly broken away, illustrating our improvements as applied thereto. Fig. 2 is an inverted plan thereof; Fig. 3, a longitudinal vertical section; Fig. 4, a transverse vertical section through platform-openings; and Fig. 5 is a perspective of a detail modification.

' Our improvements have for their object to provide means whereby street-cars may be drawn over openings in the streets between the tracks without disconnecting the horses from such cars.

Our invention consists, essentially, in the provision of a draft-bar, which may, as occasion requires, be swung to either side of the car, thus allowing the horses to draw the car over an opening between the tracks, the horses walking outside the track without being detached from the car and the tongue not being uncoupled.

At present when an opening is made in the streets for laying gas or water pipes, or for other purposes, and where such opening crosses the track of a street-railway, or is made between them, it is the practice, in order to get a street-car over such opening, to detach the horses and car and tongue, push the car along the tracks, walk the horses to one side of the same, and reconnect them and the ton gue with the car after the opening has thus been passed. This consumes much valuable time, and is a source of considerable annoyance and inconvenience to drivers and passengers; To avoid this we construct thedraw bar (hitherto made rigid and laterally immovable) in such manner that without detaching the tongue or pole therefrom, and without disconnecting the horses from the latter, said draw-bar may be swung obliquely to one side or the other of the car,

thus permitting the horses to walk'outside the tracks and pull the car over an opening between said tracks.

Our invention accordingly consists, first, in the combination, with a street-car, of a laterally-adjuslable draw-bar, or one which can be swung obliquely to one or either side of the car; and, secondly, in certain details of construction and combination, as hereinafter fully set forth. I

Referring to the accompanying drawings, A indicates the bodyot' a street-carsupported on wheels B B, running on tracks 0 0, between which is shown, at w, an opening which it is desired to cross without detaching the horses from the cars or unco pling the tongue or pole, (shown at D.)

E represents the draw-bar, which is slotted longitudinally at c, in which slot is a roller, f, whose spindle F is made fast to the body or sills of the car.

Gr shows a crank whose center g is made fast to the sills or bottom of the car, its winch g being fastened by a bolt, 9 to the end of the draw-bar E.

H represents a yoke which passes laterally under the drawbar, its ends being secured at h h to the car-sills.

e is a roller sustained on the drawbar E so as to roll against a bowed bar, I, fastened to thecar-sills at t t.

K K are linchpins or king-bolts, which pass down through openings k in the front platform of the car. One of these openings, 7c, is directly in the middle of the platform and registers with a center hole, e in the draftbar. The other openings, It k, are on either side of the opening 70, so that a pin or bolt passing through either of them willjust clear the draw-bar or pass down to one side of it.

k k are other openings in or about the front corners of the platforms, and designed for the reception of one of the bolts K K when the draw-bar is swung around to either side.

The operation is'follows Normally the parts are arranged as in Figs. 1 and 2, the draw-bar driven to a position to one side of the track. The tongue or pole not being uncoupled from the draw-bar,this causes the latter to be moved obliquely, the roller 0 moving against the bowed bar I until it reaches one of the straight ends of said bar, and the crank G swinging around to the other side, the parts occupying the position shown in dotted lines in Fig. 1. One of the pins K K is now passed down through the corner openings, k or it and inside of the drawbar. The horses are now driven straight ahead, walking by the side of the track, drawing the car across the opening. After crossing the latter the pin K is withdrawn from openings k or k, reinserted in either one of openings 70, the horses moved over to the middle of the track, restoring the draw-bar to its central position, the pin K is restored to the central opening, and the car started on its journey. All this can be done by the driver withontleaving the platform, and in less time than it takes to describe it. The object of using two pins is that one may serve as a stop in moving the draw-bar back to its normal position, and thus prevent said bar from going past the center.

Instead of having the yoke H and bow-bar I separate, as shown in Figs. 2 and 3, they may be made in one piece; or the bow-bar may be slotted at z" for the passage of the draw-bar, as shown in Fig. 5. Said draw-bar may be straight from its inner end to the pole-socket E or it may have a goose-neck, 6 to enable it to pass the brake-bar without contact with the latter.

The crank Gr serves asa check and guide for the inner end of the draw-bar, preventing it from moving too far backwardly or too much to one side in swinging round.

In lieu of a crank a platform with a guideslot, into which a pin or roller on the inner end of the draw-bar fits and in which it moves, may be employed, said platform being rigidly secured to the under side of the car-sills. This we mention as the equivalent of the crank, and as included in our invention and claims.

What we claim as our invention is as follows:

1. In combination with a street-car, a laterally-movable draw-bar, and means, substantially as specified, for holding the same firmly in place when moved to one side, substantially as and for the purpose set forth.

2. The draw-bar E, longitudinally slotted at e, and secured to the body or sills of the car by a bolt or pin, F, passing through said slot, substantially as shown and described.

3. In combination with the draw-bar E, slotted at e, and provided with a bolt, F, passing through said slot, the crank Gr, substantially as and for the purpose set forth.

4. In combination with the bow-bar I, the draw-bar E and roller e carried thereon, substantially as shown and described.

5. The bow-bar I, slotted at t, for the passage of the draw-bar, substantially as shown and described.

6. In combination with the laterally-adjustable draw-bar E, the platform A, having center openings, 70 k, and corner openings, 70 10 for the passage of pins or bolts K K, substantially as shown and described.

7. In combination with the movable drawbar E, having opening 0 the platform A, having middle opening, 70, and openings kon either side thereof for the reception of stop bolts or pins K K, substantially as shown and described.

8. The combination ofa slotted drawbar, E, rollerf, crank G, bow-bar I, roller 6, platform A, having openings 70 7c k 70 and pins or bolts K K, substantially as shown and described.

In testimony that we claim the foregoing we have hereunto set our hands this 26th day of July, 1881.
