CHARLES CARLSON, OF DEER TRAIL, COLORADO.

CAR-COUPLING.

SPECIFICATION forming part Of Letters Patent NO. 553,207, dated January 14, 1896. Application filed May 13, 1895. $eria1No. 549,209. (No model.)

To all whom it may concern.-

Beit known thatI, CHARLES CARLsoN,a citizen of the United States of America, residing at Deer Trail, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Car-Couplers; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in automatic car-couplers; and it consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a horizontal longitudinal section taken through the drawhead. Fig. 2 is a longitudinal vertical section of the same. Fig.- 3 is a vertical crosssection taken through the draw-head 0n the line 00 00, Fig. 1. Fig. 4 is a similar section taken on the line y 3 Fig. 2. Fig. 5 is a section taken through the top of the draw-head, illustrating a modified form of construction.

Similar reference-characters indicating corresponding parts in these views, let the numeral 5 designate the draw-head, to one horn of which is pivoted the coupling-j aw 6 by means of a pin 7. This jaw is provided with a tongue 6, adapted to enter the recess 8 of the draw-head. The draw-head is provided with a vertical aperture 9 for the reception of a pin 10, which is provided with a vertical groove or way 10.

hen the coupling-jaw 6 is in the coupled position, the tongue 6 engages the pin 10, which looks the jaw in place, the pin being in (See Fig. 3.) The raising of the pin'may be accomplished through the medium of any suitable instrumentality which maybe operated without going between the cars. The pin is supported in the raised position by a movable hanger 12, which automatically assumes the pin-supportin g position (see Fig. 2) as soon as the pin is raised sufliciently to allow the hanger to swing into place beneath. The pin-supporting device 12 is provided with a projection 12, which lies in the path of the tongue 6 of the jaw when the pin is raised. Hence, as the coupling-jaw moves to the coupled position, it engages the depending projection 12 of the hanger and carries the latter to the position shown in Fig. 3, allowing the pin to drop in front of the tongue 6, whereby the jaw is locked in place. The pin-supporting device may be of any suitable construction whereby it is adapted to accomplish the function stated. As shown in the drawings, it consists of a pivoted stirrup 12, having the depending part 12, projectin g downward therefrom when the device is in the pin-supporting position or that which it will normally assume if unobstructed.

The upper part of the draw-head is provided with recesses 5*, adapted to receive the stirrup-arms, which are supported therein by the pivot-pins 13, which engage lugs located on each side of each recess 5. One of these pins 13 projects into the grooved way 10 of the pin and prevents the pin from being entirely withdrawn from the draw-head, since the groove does not extend the whole length of the pin, thus forming a stop 10.

From the foregoing description it is believed that the operation of the device will be readily understood. Assuming that the coupling-jaw G is in the uncoupled position, the tongue 0 will be engaged by the corresponding jaw attached to the draw-head of the approaching car and forced inward to the position shown in full lines in Fig. 1. This movement of the coupling-jaw brings the tongue 6 to engagement with the depending projection 12 of the pin-supporting device and carries the latter to the position shown in Fig. 3, allowing the pin to drop as before stated.

The dotted lines in Fig. 1 indicate the position of the coupling-jaw when about halfway between the coupled and fully uncoupled positions.

Instead of the construction of hanger shown in Fig. 2 a half-stirrup, to which the depending projection 12 is attached, may be employed. (See Fig. 5.) It is evident this lastnamed construction would be equally operative.

Having thus described my invention, what I claim is trude, said pins forming the support for the device, one of them being adapted to enter the grooved way of the locking pin whereby 15 the latter is held against complete withdrawal, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
