SPECIFICATION forming part of Letters Patent No. 512,738, dated January 16, 1894.

i Appiicttanmea' September 19, 139s. Serin No. 485,923. (No man.)

Be it known that I, WILLIAM NEWELL, a

citizen of the United States, residing at St.

withstanding the rough usage to which coup-f 1ers are ordinarily subjected, and which is adapted to automatically effect a coupling when two cars come together.

With the foregoing ends in view, the invention will be fully understood from the following description and claims when taken in connectionwiththe annexed drawings, in which- Figure 1, is a Vertical, longitudinal section of my improved coupler with the pin in the position it assumes to hold the link. Fig.'2, is a similar view illustrating the manner in which the link automatically raises and passes the pin. Fig. 3, is a front elevation of the rock shaft, through the mediumof which the pin may be raised from the top or from either side of a car, and Fig. 4, is a front elevation of the drawhead.

Referring by letter to said drawingsz--A, indicates the drawhead of my improved coupler; and B, indicates a coupling link which maybe of the ordinary or any approved form. The draw head A, is provided in its forward end with a mouth as a, to receive the link B, and this mouth has its bottom Wall b, inclined upwardly and rearwardly as better shown in Figs. l, and 2, so as to guide the link into the chamber c, in the longitudinal center of the draw head, no matter at what elevation it (the link) enters the mouth. The side and top walls of the mouth ct are preferably converged rearwardly incoinmon with the bottom wall b, as illustrated, so as to guide the link and form a contracted throat d, between the mouth and the chamber c, which throat d, is designedk to enable the pin to hold the link in a hori- `e, when it is in operation.

zontal or approximately horizontal position as will be4 presently described.

C,indicates the pin aperture or passage of the draw-head. This aperture or passage C, extends from the chamber c, at a point adjacent to the throat d, to the top of the draw head and it is inclined rearwardly at an angle of about forty tive degrees so as to enable the link to automatically raise the pin D, from drawings, the pin D, has its lower end beveled as shown at f, so as to rest at about the angle illustrated to the bottom wall b, and enable the link to readily raise the pin, when it enters the draw head; and said pin also has its rear lside recessed. at a point adjacent to its lower end as shown at g, so as to afford a seat for .the end of the link and enable the link to hold the pin in its seat or depression The pin D, furthermore has its upper portion reduced as shown so as to afford the lshoulder h; and this Shoulder is designedpand adapted to engage the edge of a plate t', which is preferably connected in a detachable manner to the up, per side of the draw head and is designed to Vprevent the pin from being drawn out of the draw head.

For the purpose of preventing cinders, dirt, &c., from collecting in the chamber c, and lilling the same, l provide the escape passage m, which extends from said chamber to the bottom ofthe draw head as shown.

Inl order that the pin D, may be readily raised from the top or from 'either side of a car, I provide the rock-shaft E. v Illustrated in Fig. 3. This rock shaft is journaled in suitable bearings upon the end of the car andl it has an angular branch j, which is connected with the pin by a chain or the 1ike,and also has cranks lc, at its ends through the medium of which it may be conveniently rocked by a IOO person standing at either side of the car. The rock shaft E, maybe rocked by a person upon the top of the car, through the medium of a rod or chain (not illustrated) which may be connected to the angular branch j.

It will be noticed from the foregoing description taken in connection with thedrawings that my improved coupler is very simple and strong; that it embodies but few parts and none which are liable to get ont of repair; and that it serves positively and automatically to couple two cars when the same come together. Y

I-Iaving described my invention, what I claim is- 1. In a car coupler, the combination with a drawhead having a mouth, a chamber c, communicating with the mouth and provided with a depression or seat e, in its bottom, and the rearwardly inclined aperture or passage C; of` a movable pin arranged in the aperture or passage C, and adapted to be seated in the `depression or seat c; the said pin having its lower end beveled as indicated at f, substantially as and for the purpose set forth.

2. In a car coupler, the combination with a draw: head having a mouth provided with rearwardly converging walls, a chamber communicating with the mouth and provided with a depression or seat e, in its bottom, and the rearwardly inclined aperture or passage C, extending from the chamber c, to the top. of the draw head, and a plate t', connected to the top of the draw head and extending over the aperture 'or passage C; of a movable pin arranged in the aperture or passage C, and adapted to be seated in the depression or seat e, and having its lower end beveled as indicated at f, and also having a shoulder 71 adapted to engage the plate t', all substantially as and for the purpose set forth.

3. The herein described car coupler con sisting essentially of the draw head having the mouth provided with rearwardly converging walls, a chamber formed in rear of the mouth and communicating therewith and provided Wth a depression or seat e, in its bottom, the passage m, leading from the chamber c, to the bottom of the draw head, and the rearwardly inclined aperture or passage C, extending from thechamber c, to thertopof the draw head, the plate i', connected toethe top ot' the draw head and extending overvthe aperture or passage C,- anda movable pinarranged in the aperture or passage 0,1 and adapted to be seated in the depression orfseat c, and having its lowerz end beveled aszindicated at f, and also having a shoulder h, adapted to engage the plate t', all substantially as and for the purpose setforth.

In testimony whereof I aix mysignaturein -presence of two witnesses.
