CAR-COUPLING.

SPEGIFICATION forming part of Letters IPatent N 0. 743,169, dated November 3, 1903.

Original application filed September 27, 1902, Serial No. 125,092. Divided and this application filed August 20, 1903. Serial No. 170,169. (No model.)

To ctZZ whom it may concern:

Be it known that I, STEPHEN E. JA0KMAN, a citizen of the United States, and a resident of the city of New York, Coney Island, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Car-Coupler, of which the following is a full, clear, and exact descriptiomthis being a division of the application for Letters Patent of the United States, Serial No. 125,092, filed by me September 27, 1902.

The invention relates to amusement devices, such as inclined or switch-back railways; and its object is to provide a new and improved car-coupler for convenient and safe coupling of the cars and arranged to prevent coupled cars from jumping upward ofi the track, especially when running over steep inclined portions in the track of the railway.

The invention consists of novel features and parts and combinations of thesame, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement, showing two cars coupled together. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged side of the improvement as applied and showing the car-axles in sections; and Fig. 4 is a like view of the same, showing the parts in a difierent position.

Each of the cars B B is provided with a longitudinally-extendingdraw-bar O, fulcrumed at O in the truck-frame and extending over a guide-plate B beyond the end of the car, as shown in the drawings. The outward end of the draw-bar is connected by a transverse pivot O with a coupling-link 0 having a lug or projection O at each end, adapted to swing in engagement with the top of the draw-bar O to prevent the coupled cars from jumping upward off the track-rails. On the end of each car and directly over the draw-bar O is arranged a bracket 0 to prevent the projecting end of a draw-bar from being bent upward on an unusual strain.

By reference to Fig. 1 it will be seen that the bottom edges of the lugs 0 stand normally at angles to the top surfaces of the draw-bars O to allow the adjacent coupled cars to readily travel over portions of the track curved in a vertical plane; but in case a rear car should unduly press a forward car, then the draw-bar of the rear car causes an upward swinging of the connecting-link on the other draw-bar as a fulcrum until the lug abuts against the draw-bar of the forward car, thus holding this car down and preventing further upward swinging of the connectinglink, so that the following car cannot leave the track. (See Fig. 4.)

By having the draw-bars mounted to swing on vertically-disposed pivots, as shown, the cars are free to readily travel around sharp curves disposed in a horizontal plane without undue binding of the coupling members. Having thus described my invention, I

claim as new and desire to secure by-Letters' Patent- 1. A car-coupling comprising a longitudinal draw-bar pivoted on the car, to allow the draw-bar to swing sidewise, a coupling-link pivoted on the draw-bar and arranged to swing up and down, and a lug on the coupling-link, adapted to engage the top ofthe draw-bar, to prevent thecar from swinging up, as set forth.

2. A car-couplingcomprising a longitudinal draw-bar pivoted on the car, to allow the draw-bar to swing sidewise, a coupling-link.

provided on the draw-bar and arranged to swing up and down, a lug on the couplinglink, adapted to engage the top of the drawbar, to prevent the car from swinging up, and a fixed stop on the car, over that portion of the draw-bar projecting beyond the car, as set forth.

3. A car-coupler comprising longitudinal draw-bars pivoted on the cars and mounted to swing in a horizontal plane, and a coupling-link pivotally connecting the free ends of the draw-bars with each other, the coupling-link being capable of swinging in a vertical direction, as set forth.

4, A car-coupler comprising longitudinal draw-bars pivoted on the cars and adapted to swingin a horizontal plane, a couplinglink pivotally connecting the free ends of the draw-bars with each other, the c0up1ing-1ink being capable of swinging in a vertical direction, and lugs on the ends of the couplinglink, for engagement with the draw-bars, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

STEPHEN E. J ACKMAN.
