CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 236,263, dated January 4, 188.1.

Application iiled November 18, 18510. (Modei.)

To all whom it may concern:

Be it known that d, kEDWARD MOULTON RICHARDSON, of Laconia, in the county of Belknap and State of New Hampshire, have invented a new and usefullmprovement in Car-v sectional side elevation taken through the line y y, Fig. 2. Fig. 4 is a front elevation. Fig. 5 1s a sectional end elevation taken through the line z z, Fig. 3.

Similar letters ot' reference indicate corresponding parts.

rIhe object of this invention is to furnish car-couplings so constructed that the cars can be coupled and uncoupled without its being necessary for the attendant to go between the cars, and which shall be simple in construction and reliable in operation.

The invention consists in constructingacarcoupling of a coupler-head having a longitudinal;l perforation and side slots, a bar sliding in the longitudinal perforation, a cross-bar attached to the sliding bar and working in the cross-slots, pivoted horizontal bars, pivoted triangular lever-plates, pivoted upright bars, a cross-har carrying the coupling-pin, and a push-bar placed in the rear part of the longitudinal perforation, so thatthe cars can be coupled automatically as they are run together,

' and can be uncoupled by moving the sliding bar forward, as will be hereinafter fully described.

1D the accompanying drawings, A represents the coupler-head, which is connected with the carin the ordinary manner, so as to serve as adraw-bar and as a bumper-head. The coupler-head A is made with a hopper-shaped mouth, B, to guide the end of an entering link into place, and has a central perforation,C, formed longitudinally through it to receive the short rod or bar D. The bar D is placed in the perforation C, and to its middle partis attached the middle part of a cross rod or bar, E, the ends of which project through short longitudinal slots, F, formedin the sides ofthe coupler-head A, as shown in Figs. l, 2, and 5.

To the ends of the cross-bar E are pivoted the rear ends of two short bars, G, the forward ends of which are pivoted to the triangular plates H at or near the rear angles of the said plates. The triangular plates H are pivoted at their upper angles to the sides of the coupler-head A.

If desired, the triangular plates H can he made in the form of three-armed levers; but

I prefer the plates as being stronger.

I'Io theforward angles ofthe triangular plates H are pivoted the lower ends of two short upright bars, I, the upper ends of which are pivoted to the ends of the cross-bar J.

The sides of the coupler-head A are recessed to receive the bars Gr I and triangular plates H, so that the said bars and plates will be protected from accidental injury. of the forward end of the'coupler-head A is recessed to receive and protect the cross-bar J and to keep the said cross-bar in place as it moves up and down. In the center ofthe cross-bar J is formed a hole toreceive the coupling-pin K, the head of which rests upon the upper side ot' the said cross-bar J, so that the couplingpin Kean be raised and lowered by raising and lowering the said cross-bar J. In the rear part ofthe perforation Gis placed a har, L, which slides freely within the said perforation. The rear end of the bar L pro jects at the rear end of the coupler-head A.

The bar L may he placed loose in the coupler-head A, and arranged to strike against a part of the car-frame, or against a suitable stop attached to the car-frame; or the bar L can be rigidly attached to the car-frame. In either case, as the cars are run together the link attached to the coupler-head of one car will enter the mouth B of the coupler-head A of the other car and push the said couplerhead back upon the bar L, which causes the forward end of the bar L to press the bar D forward and operate the bars and plates G I J H to raise the coupling-pin K, which coupling-pin, as the coupler-head A is pushed forward by its spring,l drops through. the lilik and couples the cars.

The coupling is designed to be provided with levers, which may be connected with the ends of the cross-har E, or with the ends ot' the cross-bar J, or with the push-barkas may be desired or convenient7 and which project The upper side IOO into such positions that they can be reached and operated from the sides of thecars to raise the coupling-pin K to uncouple the cars, which levers are not shown in the drawings. A chain can be attached to the coupling-pin K 0r to the cross-bar J, and extended to the top ot the car, so that the cars can be uncoupled from the top of the car, if desired.

Having thusdescribed my invention, I claim as new and desire to secure by Letters Patent- 1. A car-coupling constructed substantially as herein shown and described, consisting ot the coupler-head A, having a longitudinal perforation, C, and side slots,F, the sliding bar D, placed in the perforation G, the cross-bar E, attached to the sliding bar D and working in the slots F, the pivoted horizontal bars G, the piroted triangular lever-plates H, the pivoted upright bars I, the cross-bar J, the couplingpin K, and the push-bar L, placed in the rear part of the perforation C, as set forth.

2. In a car-coupling, the combination, with the coupler-head A, having longitudinal perforation C and side slots, F, and the couplingpin K, of the sliding bar D, the cross-bar E, the pivoted horizontal bars G, the pivoted triangular lcver-plates H, the pivoted upright bars I, and the cross-bar J, substantially as herein shown and described, whereby the coupling-pin can be raised by the forward movementof the sliding bar, as set forth.

3. In a car-coupling, the combination, with the coupler-head A and the sliding bar D and its attachments, of' the push-bar L, substantially as herein shown and described, whereby the said sliding bar and its attachments will be operated automatically to raise the coupling-pin as the cars are run together, as set forth.
