CAR-COUPLING.

rPECIJEICLL\ '.IIO1\ forming part of Letters Patent No. 390.766, dated October 9, 1888.

Application filed June 5, 1888.

.T0 all wtom it may concern:

Be it known that I, ABRAHAM GW. FOSTER, of NVhitesburg, in the county of Carroll and State of Georgia, have invented a new and Improved Oar-Goupling, of which the following is a full, clear, and exact description.

This invention relates to car-couplings, and has for its object to provide a car-coupling in which the coupling-pin may be set to be automatically thrown into coupled position with a coupling-link and the latter at the saine time guided into place 'in the draw-head, and by means of which also the uncoupling may be effected without going between the ears.

The invention consists in a car-coupler, and in details of construction connectedtherewith, constructed and arranged as hereinafter described and claimed.

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

Figure 1 is a plan View of the invention in set position for coupling. Fig. 2 is a plan view thereof arranged with old form of draw-head and provided with operating-levers projecting at cach side of the car. Fig. 3 is an end view, with parts broken away, ofthe device in Fig. 1. Fig. Lt is an end view of the device in Fig. 2 after the coupling has been effected. Fig. 5 is a side View, partly in section, showing the `position of coupling in Fig. 3 after the coupling has been effected. Fig. Gis a view on the opposite side from that in Fig. 5; and Fig. 7 is a detail, part-ly in section and broken away, of locking-rod for holding coupling-pin in position to be coupled.

In carrying out this invention I preferably useit in connection with a special formofdrawhead, (shown in Figs. 1 and 3;) but it may be ,employed with the old form of draw-head, as shown in Figs. 2, 4, 5, and 6.

Referring to Figs. 1 and 3, the draw-head l is formed with an opening, 2, for a link, located below its center and having its lower side, 2', inclined downward toward its mouth. The height of the opening 2 is such as to cause the end of a solid link to lit snugly therein, but is of snfiicicnt width to permit of lateral movement when the ends of the cars move over a curve. By having the opening 2 below the sel-mi No. 276,113. (No man.)

center of draw-head it will be in position to receive the link, and the link, fitting snugly therein, as just stated, will be prevented from sagging. 1n order to set the coupling-pin to automatically couple with the link and also to guide the link into the draw-head, the following mechanism is employed:

To one side ofdraw-head1is boltedabracketarm, 3, having mounted thereon a vertical bar, 4, provided with an inclined slot, 5, through which the end of bracket-arm 3 projects, having a nut, 6, for retaining bar 4in place. The bar f1 is formed with a horizontal arm, 7, extending across the draw-head 1 beneath its opening 2, and is operated by means ofa lever, 8, pivoted tothe coupling-pin 9 and connected at its inner end to baril by means of a bolt, 10, on the latter, located in a slot, 11, in the end of lever 8 and adapted to move therein. The outer en'd of leverl 8 is located at the side of a car, and in the case ofpaSsenger-cars is formed with the upturned handle l2, as shown. On the opposite side of draw-head 1 from the bracket-arm 3 is pivoted a tripping device consisting of an arm, 13, having a counter- Weight, 1-1, depending from its pivotal portion 15, and a stop, 18, near the pivotal point.

Upon the bolt 1G, on which the arm 13 is mounted, is a washer, 17, located between the arm 13 and draw-head 1, and on the outer end of bolt 16 is a loosely-pivoted plate, 18, having an inclined perforation, 19, through which passes a rod, 20, having an eye, 21, at one end engaging bolt 22, on which lever 8 is pivoted, and at its other endv formed with teeth 23, adapted to engage the edge 24 of perforation 19. Vhen the coupling-pin 9 is raised by means of the lever 8, the rod 20 is drawn up through perforation 19 until one of the teeth 23 engages the edge 21 of perforation 19, thereby holding the coupling-pin 9 in position for coupling, as shown in Fig. 3. In this position the lower portion, 25, of arm 13 is held out by counter-weight 14, and upon the approach of a ear to be coupled is forced back by a corresponding portion, 25, on the meeting coupler,thereby releasing theeoupling-pin 8 and allowing the same to drop into coupled position with the link 9. As the arm 25 is forced back, the pin 18', coming in contact with the plate 18, raises the said plate, and at the` same time the rear face of the arm 25 engages the rod 20 and raises the same, disengaging its tooth from the edge of the perforation 19 of the plate 18, when the rod will slide through the said perforation and the pin 8 drop into a coupled position. As the latter approaches the opening 2 ot' draw-head 1, it is raised and guided into the opening by moving down the outer end of lever 8, the fulcrnm thereofin this movement being on the bolt 22 in coupling-pin 9, which action raises the bar 4 and by reason of the inclined slot 5 causes the bar 4 to ride up on the arm 3, thereby moving the lower end of bar 4 forward and upward and raising its horizontal arm 7 in front of opening 2, and with it the coupling-link 5) into position to enter the opening.

Thelower portion, 25, of arm 13 is provided with a laterallyextending pin, 2G, which, in case the parts of a meeting coupler should be reversed, would be acted upon by the bar 4 to effect the automatic coupling. The coupling pin 9 may be secured in coupled position by means of teeth 27 on the upper portion, 28, of arm 13, with which the lever 8 is throwninto engagement, as shown in Fig. 5.

NVhere the invention is applied to the old form of clrawhead 29, as shown in Figs. 2 and l1, the vertical bar 4 and counterweighted arm 13 are pivoted to the ends of a bar, 30, lying across the top 'of drawht ad 29, and are held in place by nuts G. The bar 30fis secured to draw-head 29 by vertical bolts 31 projecting through a bar, 32, extending across thennder side of drawliead 29, and held by nuts G.

The operation ofthe parts is similar to that alreadydeserihed in connection with Figs. 1, 3, 5, and 6.

The lever 8 is provided with horizontal handles 33, extending to the sides of the ear, which is the preferable form in connection with freightears, but may be formed with vertical handles 12, as in Fig. 1, for passengervcars.

It will thus be seen that by means of this invention the coupling-pin may be set in po sition to be coupled from either side of a car, the link may be raised and guided into the draw-head in the act of coupling, and the coupling will be effected automatically.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. 1n a car-conl'iling, the combination, with a coupling-pin, ot' a lever for raising the coupling-pin, a rod for holding the coupling-pin in raised position, and an automatically-releasing tripping-catch for holding the rod in raised position and releasing the same, substantially as shown and described.
