CLAY N. HEAIDDING, OF CHEHALIS, W'ASHINGTON, ASSIGNOR OF ONE-THIRD T0 GEORGE A. HANSEN, 0F CENTRALIA, WASHINGTON, AND ONE-SIXTH TO CHARLES B. HEAD- IDING- AND IN GTON.

Application filed August 17, 1916.

To all whom it may concern:

Be it known that I, CLAY N. HEAD ING, a citizen of the United States, residing at Chehalis, in the county of Lewis and State of l/Vashington, have invented new and useful Improvements in Car-Couplings, of which the following is a specification.

This invention relates to an improvement in car couplings, proposing a coupling of the general type shown in the patent to Schaefi'e'r N 0. 567,866 of September 15, 1896.

The present coupling may be regarded as an improvement on the coupling shown in the Schaefler patent referred to, and as such,

its objects are to provide a coupling having all the advantages of the Schaelfer coupling and which moreover will be adaptable to extreme curves and will have a wider field of useful application, being capable of advantageous use by virtue of the improvements to be hereafter explained, on street cars, dump cars and logging trucks.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of the improved coupler;

Fig. 2 is a plan view, the pin being shown in section;

Fig. 3 is a longitudinal sectional view showing the pin in its inoperative position;

Fig. 4 is a longitudinal sectional view on the line 4-4 of Fig. 2 showing the pin in its operative position;

Fig. 5 is a perspective view of the pinsupporting head.

Similar characters of reference designate corresponding parts throughout the several views.

The coupling includes a draw head 1 having a mouth 2 in its end for the entrance of the link, said mouth having outwardly flaring side walls and opening into a chamber 3 located in the body of the draw head and extending rearwardly for an appropriate distance.

The coupling also includes a vertically movable pin a, a link 5 and a supporting head 6 for said pin. The head 6 is disposed in the chamber 3, the bottom of which is stepped and includes a base 7 and a shelf or ledge 8 located in the rear of said base at an elevation slightly less than midway between Specification of Letters Patent.

said base and the upper face of the draw head.

The chamber 3 communicates with an opening 9 in the upper face of the draw head (Figs. 1 and 2), which opening is normally closed by a removable dust guard or plate 10. V

.The head 6 has a forward portion of greater vertical depth or thickness than its rearward portion; and the under face of said head is of rearwardly and upwardly oblique form, as at 11. i The enlarged forward portion of the head 6 rests upon the base 7 when the coupling is not in use and the oblique or cam face 11 engages the upper front edge of the ledge or shelf 8 whereby said ledge or shelf supports the rear portion of the head and causes the head to have a generally forward and downward inclination. The head 6 is provided with a central forward extension or rib 12 which, when the coupling is not in use, engages under the lower end of the pin 4, as shown in Fig. 3. The said pin, Which has a round cross section, is slidable through alining vertical openings let and 15 which are located Within the area of the flaring mouth 2.

In the use of the coupling, the link 5 is inserted inthe flaring mouth 2 in the well known manner and ultimately engages the rib 12, the further inward movement of said link pushing the head 6 rearwardly until the rib 12 passes from under the pin 4, at which time said pin drops, by gravity, through the openings 14 and 15 until its downward movement is arrested by the en agement of its headed upper end 16 upon tlie upper face of the draw head. In connection with the rearward movement of the head 6 by the link 5, the forward end of said head is canted upwardly and ultimately comes to rest upon that portion of the link 5 which is disposed in the rear of the pin 4;. The weight of the forward portion of the head 6 on the link 5 tends to coimter-balance said link and to hold it in a true horizontal positon so that it will freely enter an opposite draw head.

For the purpose of guiding the head 6 in its movements and of limiting the forward movement of the head when the link 5 is removed, the side walls of the chamber 3 are provided with perpendicular front shoulders 17 and with rearwardly and upwardly inclined rear shoulders 18; and the head is provlded at lts sides wlth triangular lugs 19 for cooperation With the shoulders 17 and 18. lVhen the head 6 comes into its lowermost position, as indicated in Fig. 3 the lugs 19 engage the shoulders 10 at their lower ends; and during the rearward movement oi said head, the lugs 19 ride along the shoulders 18 which also serve as a gulde for said head in its forward and downward movement, i. (2., from the position shown in Fig. l to the position shown in Fig. 3.

The opening let for the pin -l is located somewhat in advance of the chamber 3 which ineloses the head 6 and is connected with said chamber and also with the opening 9 by a narrow slot 20 through which the rib 12 works.

I claim- In a coupling, adraw head having a mouth provided with outwardly flaring side walls, alining vertical openings within the area of said mouth above and below the same, an internal chamber in the rear of said mouth Copies of this patent may be obtained lbr five cents each, by addressing the Gom mi'ssi oner of Pa-lant'm- I havin r arr-elevated; le'd e: or shelf in the rear b portlon thereof, and a narrow slot extending between the upper of said vertical openings and said cliiainloer a pin of round, cross section movable through said openings, a pin supporting head arranged within. said chamber,. said head having its forward'portion of greater vertical depth than its rear portion and provided with a central forwardly projecting rib which extends through said slot for engagement under said pin when the latter is elevated, the rear portion of said head engaging said shelf, and means for supporting said head inthe pin-supporting sosition thereof in a forwardly and downwardly inclined position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
