CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 395,040, dated December 25, 1888.

Application filed March 30, 1888. Serial No. 268,98}. (No model.)

To all whom it may concern.-

Be it known that we, DANIEL B. DAVIS and JOSIAH J. FIsHER, of Laramie, in the county of Albany and Territory of WVyoming, have invented a new and Improved Car-Coupler, of which the following is a full, clear, and exact description.

Our invention relates to a car-coupler, and

' coupled.

The invention consists in the construction and combination of the several parts, as will be hereinafter described, and fully set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a partial perspective view of a car having our coupler attached. Fig. 2 is a central vertical section through the coupler, and Fig. 3 is a bottom plan view of the same attached to a car. i

The drawhead 10 is supported centrally beneath the car by means of a draw-bar, 11, attached to the rear end of the draw-head and projected through an aperture, 12, in a transverse beam, 12, secured to the floor of the car, as best illustrated in Fig. The aperture 12 is of greater diameter upon the outer face of the beam than upon the inner face, and is so constructed to admit of a limited vertical and lateral movement of the drawhead, as will be hereinafter set forth. The draw-bar is secured in position by means of a washer to the rear of the beam and a nut engaging the washer. Between the beam and the draw-head a spring, 13, is coiled upon the draw-bar,whereby when the cars are coupled and the opposing draw-heads meet the strain will be removed from the draw-bar.

The draw-bar is provided with a central longitudinal bore, 14, and the usual pin-open ing, 15, leading into said bore. WVithin the bore, a block, 16, is held to slide, which block is preferably cylindrical, and from its rear end a coil-spring, 17, is projected, having a bearing against the rear wall of the bore 14. The block 16 is provided at the front, upon the under side, with an angular recess, 18, whereby a lip, 19, is obtained.

The draw-bar projects beyond the sill of the car, and is surrounded by a rectangular frame, 20, consisting of a buffer-block, 21, parallel side pieces connected to said bufferblock and the rear beam above referred to, in which the end of the draw-bar is pivoted, and a strap, 27, connecting the under sides of the beam at the-front. The forward end of the draw-bar is of greater height than the remaining portion, the projection thus produced being adapted to engage the bufferblock when met by an opposing draw-head. This portion of the draw-head may also be utilized to carry an extra link by producing a suitable cavity therein above the bore 14.

Upon the front of the draw-head a vertically-projecting plate, 22, is attached or cast integral therewith, the rear face of which plate is in alignment with the pin-aperture, the purpose of the front plate being to support the coupling when said pin is held in its normal or elevated position, as illustrated in Fig. 2.

A shaft, 23, is projected above the sill of the car transversely the ends, and held to slide and turn in suitable bearings, 24, as best shown in Fig. 1. Vhen the shaft 23 approaches the center of the car, it is carried downward and transversely beneath the car and upward to form a yoke, 25, which yoke is adapted to surround or embrace the draw bar. The ends of the shaft 23 may be provided with cranks 26 or a wheel or any form of grip device desirable.

In operation, when the draw-bar is at rest or when the car is uncoupled, the block 18 is carried rearward, the coupling-pin inserted in its aperture, and retained in said aperture above the link-opening by engaging with the lip 19, as shown in Fig. 2; or the block 18 may be suffered to extend as far to the front as the spring will admit and the coupling-pin be allowed to rest upon the upper surface of the block 18. In either event, when the drawhead is met by an opposing draw-head the link, entering the bore 1% and ei'igae ing the surface of the block beneath the lip 19, propels the said block rearward, which action, releasing the coupliire-pin allows it to drop down and pass through the link, ell'ecting a coupling.

If the opposing draw-head is ot' greater height than the one to be coupled with, by means of the shaft 23 the latter draw-head may be elevated to meet the o posing one; or,ii' the o 'i 'iosing d raw-head is not centrally 5 a central yoke embracing the draw-head, subloeated, by pulling or pushing upon the shaft .i as

heads may be brought to align one another. it is obvious that the coupling may be eft'eetually accomplished without the necessity l of the operator passing between the cars.

Having thus fully described our invention, we claim as new and desire to secure by Let ters Patentoccasion may deinai'id, the two d raw- 1. The con'ibination, with a draw-head pro vided with apin-opening' and a vertical t'ace projection in front of the pin-opening, of a spring-actuated block held 1:0 slide within the same and recessed upon the underside at the front to receive a link, a coupling-pin adapted to be normally supported by the block, and means, substantially as shown and described, for manipulating the drmv-head Vertically or laterally, as and for the purpose specified.

2. The (oinbination, with the body of a ear, of a draw-head supported beneath the ear to have a limited lateral and vertical movement and a transverse shat't loosely held in engage ment with the end of the car, provided with stantially as shown and described, and for the purpose specified.
