COUPLING.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed July 15, 1909. Serial No. 507,786.

To all whom it may concern:

Be it known that I, FRED C. BOWLES, a citizen of the United States, residing at Groton, in the county of Brown and State of South Dakota, have invented certain new and useful Improvements in Couplings; 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.

My invention relates to couplings and the object of the invention is the production of a device which is especially adapted for coupling the separator with a traction engine whereby in moving from place to place, the engine and separator may be readily coupled or uncoupled.

A further object of the invention is to provide a coupling of this character which may be readily utilized in coupling the cars of railway trains.

IVith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the drawings, Figure 1 represents the side elevation of the device; Fig. 2 is a longitudinal section; Fig. 8 is a transverse section on the line 3-3 of Fig. 1; and Fig. 4 is a side elevation of a modified form.

Referring more especially to the drawings, 1 represents the body of a coupling which is constructed as shown in Fig. 1 of a rectangular bar of metal formed at its inner end with a coupling eye 2, to which a suitable clevis 3, or other suitable connecting device may be attached. The outer end of the body is bent upwardly as at 4, approximately at a right-angle to the body and forms a retaining lug or projection for the engagement of the coupling or the ring which is carried by the traction engine.

Intermediate the length of the body, I secure spaced standards 5, by means of a suitable through bolt 6, and pivot to the upper end of the standards, an elongated latch bar 7, whose outer end lies upon the top of the projection 4, and is normally held in such position by a locking cam or eccentric 8, which is pivoted intermediate a pair of standards 9, secured to the body 1, by a through bolt 10. The eccentric 8, has secured to it, an operating lever 11, which has in its free end a ring 12, which is connected to a tripping dog or other suitable device for releasing the eccentric from the latch bar 7. When such release is accomplished, the latch bar is thrown to the position shown in dotted lines in Fig. 1 by means of a compression spring 13, arranged between the body and the latch bar.

From the foregoing description, it will be readily seen how the threshing machines may be connected and disconnected to the traction engine without stopping the latter.

In Fig. 4, I have shown, a modified form of coupling wherein the body 14, is bent back upon itself as at 15, to form a coupling eye 16, which may be secured to the draw bar. The front end of the body 14, is provided with a beveled lug 17, upon which the latch bar 18, is adapted to rest. As in Figs. 1 and 2, the latch bar is shown as pivoted to standards 19, and plays between similar standards 20, upon which is pivoted the locking eccentric 21. In this instance, the eccentric has connected to it, one arm of a toggle lever 22 whose opposite end or arm is connected to the body. This toggle lever may be operated in any suitable manner to release the pressure upon the latch bar 18.

In operation, the coupling link is placed upon the inclined forward face of the bar and as the car to be coupled moves toward the coupling device, the link rides up on the lug 17, and forces the latch bar away from its seat thereon and drops into the space formed between the lug and the standards 20. The toggle lever may now be operated to lock the latch bar in proper position to prevent the removal of the coupling link.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim is:

1. A coupling comprising a body, a link holding member integral with the body, standards carried by the body, a latching bar pivoted to one of the standards and adapted to engage the link holding member, a spring for normally forcing the latching bar away from the link holding member, and an eccentric for locking the latching bar against the tension of the spring.

2. A coupling comprising a body, a link holding member integral with the body, a pair of standards pivoted to the body, a latching bar pivoted to one set of standards and operating within the other set of stand ards, a spring for normally forcing the latching bar away from the standards, and an eccentric pivoted to one set of standards for locking the latching bar against the tension of the spring in engagement with the link holding member.

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

FRED C. BOXVLES.
