' CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 254,852, dated March 14 1882.

Application filed August 12, 1881. (N model.)

To all whom it may concern:

Be it known that I, \VILLIAM WYNKOOI WATKINS, of Bellevue, in the county of Jackson and State of Iowa, have invented a new.

and useful Improvement in Gar- Couplings, which improvement is accurately set forth in the following specification, reference being had to the accompanying drawings.

The object of my invention is to make a car coupler that can be operated with safety, and that the parts which wear the most-the link and pincan be easily renewed, and that can be coupled without any special link to those in most common use.

The drawings are described as follows: Figure 1 is a top view; Fig. 2, a vertical central longitudinal section, and Fig. 3 a side elevation.

Fig. 1 represents a top view of one of the draw-heads, with the link L lying in its place and the cover open. In this figure C represents the cover hinged to the side of the drawhead. F represents the thickest part of said cover, made to fit into the recess where the link is placed, nearly down to the link when the link is in its place. The link is of the same size,or nearly so, as those in most common use. A represents the. draw-head, which might be made of different materials by changing its proportions to suit the strength of the material used. The part of the draw-head where the link works increases in size in all directions from the center of the pin toward the outer or buffing end to allow sufficient play or motion to the link. P represents the pin for the link to draw on, securely fastened by bolt B, out a, key it, and the higher part I), and removed with reasonable ease when wished. Said pin can be placed at an angle and screwed in, ifpreferred. S represents the staple, ri veted through the side of the draw-head, by which the cover could belocked, ifa lock asa means offastening. were preferred to a spring-catch on the cover or draw-head, or to put through the staple. d 0 represent the line on which the sectional view shut, but not locked.

The size of the bufling-snrfaces is the same, or nearly so, as that of most draw-heads, but could be changed, it wished.

It is intended that the cover should be made of cast-iron,the draw-head of wrought-iron, or

steel if it is wished, and the pin P of tolerably-hard steel, to make it wear along time. The link L is to be of either wrought-iron or steel.

The coupling or uncoupling is made after the cars are pushed together and are at a standstill, therefore without any risk ofinjury to any one.

When a coupling is wished to be made with cars using a diiferent draw-head, then to do so the link should first be placed in this drawhead.

The name of this car-coupleris The Safety Gar-Coupler. It could be used with outa cover with as much or more safety, I believe, than the most of car-couplers now have, but it is arranged to fasten the link in its place, so that no cars would come unfastened until wished by theparties who have charge of them.

I claim as my invention- The combination of a car-coupler, substantially as described, with a drawhead that is open on the top, with a cover that can be looked, a pin that is fastened and can with reasonable ease be removed when wished, and all in connection with a link of the same size, or nearly so, as those in most common use, and that may be coupledto cars using such or similar links.
