MICHAEL CAVANAGH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF- ONE-THIRDVTO MATTHEW DITTMANN, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 539,932, dated May 28, 1895.

Application filed May 15, 1894:. Serial No. 511,285. (No model.) I

To all whom, it may concern: Be it known that 1, MICHAEL CAVANAGH, a citizen of the United States, residing in the city and county of Philadelphia, State of 5 Pennsylvania, have invented a new and useful Improvement in Car-Couplings, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a car coupling formed of a draw-bar having a head, a knuckle pivoted thereto, a lever for locking the heel of the same after it has been moved into coupled position, means whereby said draw-head is moved with the truck of the car, and means for actuating the couplingdevice from the platforms or outside of the car, as will be hereinafter set forth and claimed.

Figure 1 represents a side elevation of a car-coupling embodying my invention. Fig. 2 represents a plan view of the coupling, the platform of the car being removed. Fig. 3 represents a side elevation of the draw-head, partly broken away. Fig. 4 represents an elevation of the opposite side of said drawhead, showing the interior thereof. Fig. 5 represents a sectional view on the line mm, Fig. 8.

Similar letters of reference indicate corre- H designates slots in the top and bottom walls of the draw-head, on the top wall whereof are cars J, to which is pivoted a lever K, which plays in said slots H andthe recess of the draw-head, and has secured to it 5 a chain L, which is suitably attached to the arm M of a rock shaft N, the latter being properly journaledunder the platform A of being connected by the bolt or pin S, with the supporting bar T, the latter being secured to the truck 0, said block, bracket and support vibrating together, while the draw-bar vibrates independent of the same during the oscillations of the car and of thecoupling and the latter may thus always be centered with respect to the tracks.

The operation is as follows, the parts being in the position shown in-Fig.'1: When the couplings of two cars come together, the heels Gr of the knuckles E are struck and forced in,

raising'the levers until the said heels have passed the same, whereby the lever falls and engages with the back,of the knuckle, the coupling thus being accomplished. When it is desired to uncouple the cars, either of the handles U is moved in the direction of 75.

the arrow, thus drawing the chain L, where by the lever K is raised clear of the heel G, so that the knuckle E swings or'turns outwardly, and is disengaged from the opposite coupling. 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Inacar coupling, a-draw head, a truck with projecting brackets, a recessed guide block for said bar at the front end of said bracket and a supporting bar with which said block is connected by an axial pin, said parts being combined substantially as described.

2. A car platform having a draw bar pivot- 0 ally secured thereto, a car truck with forwardly projecting brackets, and a recessed guide block carried at the front end of said brackets, said bar being supported onsaid 2 ssaes block and freely moving in the recess in the block, the said bar being adapted to be at same, said'parts bei'ng'combined substantially cached to the truck of the car, substantially 10 as described. as described.

3. The brackets P, the guide-block Q with 5 tongues R, the coupling head D, and the draw- MICHAEL OAVANAGH bar B which carries said head and is adapted Witnesses: to vibrate within said block, in combination. JOHN A. WIEDERSHEIM,

with a supporting bar T which carries said E. H. FAIRBANKS.
