JAMES N. ARMOUR AND ANDREW J. HANCOCK, OF CHANUTE, KANSAS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 505,892, dated October-3, 1893.-

Application filed May 31, 1893. Serial No 476,018. (No model.)

To all whom it may concern.-

Be it known that we, JAMES N. ARMOUR and ANDREW J. HANCOCK, citizens of the United States, residing at Ohanute, in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Car- Couplers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement 1n car couplers and consists in thev construct1on and arrangements of parts hereinafter described and definitely pointed out in the claim. The object or purpose of this invention is a provision of an improved automatic car coupler to be simple in its construction, strong, and durable and adapted for application to the now commonly used pin and link coupler.

further object of the invention is the pro- 1S1l{0I1 of improved means for adjusting the These objects are obtained by the construction illustrated in the accompanying drawings wherein like letters of reference indicate corresponding parts in the several views and in which- Figure 1 is a perspective view of the improved coupler. Fig.2 is a longitudinal vertical section. Fig. 3 is a bottom plan view and Fig. 4 is a front elevation.

In the drawings A represents the draw bar,

ing therein which registers with the pin opening in the draw-head.

A longitudinal tapering channel E is formed in the bottom of the draw-heads, the rear section of which is reduced in width and terminates at a point midway the length of the draw bar. In this channel is placed a sliding plate F, havinga rodfon its rear end on which a spring f is sleeved. The rear end of this rod passes through a metallic button f against which the end of the spring ongagesgthe opposite end of the spring abutting against the rear end of the plate.

Midway the length of the plate is formed an elongated slot in which a retaining bolt or screw is placed whereby the plate is held in position and allowed a reciprocating movement against the tension of the spring.

G is a catch formed on the under side of the plate having a beveled front'face, a lateral groove 9 and a vertical central groove 9 registering with an elongated opening q through which the end of the pin passes when the same is lowered.

On the forward end of the plate F is formed an upwardly extending flange H having aboveled upper edge and adapted to fit in a depression formed in the front face of the lower edge of the draw-head. This recess is of a depth corresponding to the thickness of the flange so that when the flange is forced back into the recess the same will form an even continuation of the front face of the drawhead.

In operation the pin is placed in the opening of the upper cross bar of the frame, the frame being raised until the lower cross bar engages the horizontal groove in the catch on plate F, this catch being in direct alignment with the lower cross bar, so that when the frame is forced up by any suitable means the cross bar will engage the beveled face of the catch and force the plateF back permitting the cross bar to enter the grooves at which moment the plate is forced forward by the spring thereby holding the frame with the pin in an elevated position. When the drawheads come together the flanges on the plates F are forced into the recesses thereby forcing the plate back releasing the lower cross bar of the frame and permitting the pin to fall and couple the link. By the employment of the flange the impact of the draw-heads is transmitted directly to the draw-heads, thereby preventing injury to the plate and its adjuncts.

Directly in the rear of the chamber in the draw-heads is formed a cavity I in which a link adjuster K works. This adjuster consistsof a disk having a centralopeningthrough which a shaft K passes, the latter extending to the outside of the draw-heads atone end and having a crank K secured thereon. The

too

disk is formed with a tapering projection 7c having inclined sides and arranged directly in the path of the link. The upper end of this projection is normally held in substantially a vertical position by the weight of the crank on the end of the shaft thereof so that if the outer end of the link which normally inclines downwardly is desired to be raised it is only necessary to elevate the crank which depresses the extension of the disk onto the link forcing the same down to any desired point and thereby elevating the outer end, so thatthe same will register with the opening in the adjacent drawing.

It is evident that minor changes can be made Without departing from the principle of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

In a car coupler, the combination with a draw-head having vertical grooves in its sides and a channeled lower face of a vertically sliding frame having an apertu red upper cross bar, a pin in the aperture a lower cross bar on the frame, a sliding plate in the channel having a rod on its rear end, an abutment through which the rod passes, a spring sleeved on the rod, an upwardly projecting flange on the plate of a thickness corresponding to the thickness of a recess in the face of the drawheads and having a beveled upper edge, an inclined catch on the plate in line with the cross bar of the frame, and means for slidingly securing the plate in the channel, substantially as described.

In testimony whereof We aliix oursignatures in presence of two witnesses.
