CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 493,638, dated March 21, 1893. Application tiled December 28, 1892. Serial No. 456.528. (No model.)

To @ZZ whom it may concern.-

Be it known that l, CLARENCE MoRErr, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Car-Couplings, of which the following is a specification.

I will describe a car coupling en'ibodying my improvement and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a horizontal section of a coupling embodying my improvement, the upper portion of the two draw-heads being entirely removed. Fig. 2 is a plan or top View of one of the draw-heads. Fig. 3 is a vertical longitudinal sect.ion,taken at the plane of the dotted line 3 3 Fig. l. Fig. 4 is a View like Fig. 3, but showing parts in different positions. i

Similar letters of reference designate correponding parts in all the figures.

I have illustrated my invention in a duplex coupler.

A A2 designate draw-heads which may be made of any suitable material and of any approved form. They are fastened to draw-bars B B2. Each draw-head has two practically distinct portions a a2 which, in the present example of my improvement are represented as being absolutely distinct by reason of the fact that a partition a extends longitudinally throughout the interior of the draw bar. The partition really divides the draw-bar into two compartments. From the forward end of the portion or compartment CL of each draw-bar a projection a3 extends. This is represented as being made flat on the bottom and flat throughout the greater part of its top surface. At the forward end, it is provided with a notch at, and rearward of this notch, it has a hole a5 extending through it. At the forward extremity and adjacent to the sides of the notch a4 are two inclined rails or projections a. The rear extremities of these rails or projections are shown as quite abrupt. Behind the rails or projections a6 is a disengaging device, here shown as made in the form of a rocking lifter a7 having its forward extremity notched or forked. It is provided with journals or mounted upon a rock shaft a8.- In the present instance, it is mounted upon a rockprovided in the portion or compartment a2 with a rocker 0,9 constituting another disengaging device.

In the portion or compartment a2 is a dog or locking device made in the form of a vertically moving pin d10, which passes through a hole in the top of the draw-head and also through a hole in the bottom. It is shown as provided with transverse projections all. The The rocker a9 is notched or forked at the forward end so as to embrace the pin d10 beneath the projection au. Gbviously, by tilting the rocker, the pin am may be raised or lowered. The transverse projection all may be engaged with vertical slots formed in the side walls of the portion or compartment a2 of the drawhead.

It will be readily understood that'when two couplers are moved together, the projection as of each draw-head will enter the portion or compartment a2 of the opposite draw-head, and those portions at the side of the notch a4 will embrace the pin am belonging to said portion or compartment. The rails a will work along the transverse projection a of said pin d10 and raise the pin until said inclines rails or projections a6 have passed entirely beyond the transverse projections d of said pin am, whereupon the pin. 0,10 will drop and its transverse projections will engage with the rear side of the inclines rails or projections a6. Thus the two draw-heads will be coupled together. In order to uncouple the draw-heads, the rock shaft a8 will be oscillated so as to raise the rockers a7 a9. The tilting of the rocker a9 will effect the lifting of the pin d10 belonging to the draw-head whose rock shaft a8 is oscillated. The tilting of the rocker a7 will cause the outer notched or forked end of such rocker to force upward the transverse projection all of the pin am belonging to the opposite draw-head and thus raise such pin.y

The rock shaft as, or the journals of the rockers when the rockers are formed With journals, may, outside the draw-heads, be provided with any suitable devices, whereby the tilting of the rockers may be effected, as, for instance, a crank arm B may be fastened to one end of such rock shaft, or a hand wheel, C, may be used in lieu thereof, or a crank B may be used and combined with a link, D,

IDO

pivotally connected. at one end therewith, and at the other end with a lever E, fulcrumed upon a standard erected upon the draw-head or car platform.

It will be seen that by my improvement l provide in a very simple and efficient form a coupler which may be made either single or duplex and whereby cars maybe automatically coupled and readily uncoupled.

Draw-heads embodying my improvement may be constructed so as to operate with an ordinary link and pins. To this end, a hole als may be provided directly through the partition a for the reception of a pin am. The partition may be notched above the plane of the inclined rails or projections so as to permit of the insertion of an ordinary link far enough to intersect the hole a and engage With the pin C014.'

Obviously, it is important that a coupling should be so constructed as to operate equally Well when a car is reversed end for end. Indeed, it may almost be said that no car coupling would be of any practical value it' incapable of operating on a reversal of the car. By my improvement, I afford a double connection, each complete in itself, and capable of operation even if the other should become disabled.

A very valuable feature of my improvement is the use of a part Which is movable relatively to a draw-head in combination with another`part which is immovable with the drawhead. By this combination of parts, great strength and durability are afforded. It is impossible to utilize this combination of parts and to afford provision for reversing a car without adopting a duplex arrangement of coupling devices.

A vertically moving part in a car coupler is advantaneous. It is impossible to employ such a part and provide for the reversal of a car, excepting a duplex arrangement, of which myimprovement affords an example, is adopted.

It will be seen that the meansl employ for shifting the movable parts to uncouple a car are combined with the drawheads, and therefore it is obvious that my coupling does not necessitate the use of any special platform or the employment of devices mounted upon a platform for uncoupling one car from another.

What- I claim as my invention, and desire to secure by Letters Patent, is

l. The combination with a draw-head, of a vertically moving pin having transverse projections, a lifter therefor and a handle outside of the draw-head whereby said lifter may be operated, substantially as specified.

2. The combination with a draw-head, of a vertically moving pin having transverse projections, a rocking lifter therefor and a handle combined with the shaft or journal of said lifter, substantially as specified.

3. The combination with a draw-head having two portions or compartments, of a pinin one portion or compartment provided With transverse projections or shoulders, a lifter for said pin arranged in the same portion or compartment, an immovable projection from the other portion or compartment, inclined rails or projections extending beyond the other port-ion or compartment and a lifter 1n the latter compartment in rear of the inclined rails or projections, substantially as specified.

4. The combination with a draw-head haying two portions or compartments, of a pin 1n one portion or compartment provided with transverse projections or shoulders, a lifter for said pin arranged in the same portion or compartment, an immovable projection from the other portion or compartment, inclined rails or projections extending beyond the other portion or compartment and a lifter in the latter compartment in rear of the inclined rails or projections, both the said lifters being mounted upon a common rock shaft,substan tially as specified.

In testimony Whereofl have signed my name to this specification in the presence of two subscribing Witnesses.
