CQ'UPLING' MECHAYNTSFJI.

Application filed August 16, 1916.

To all whcmz't may concern Be it known that 1, WILLIAM BARBER, a citizen of the United States, residing at New York, in the county of Kings, State of New York, have made a certain new and useful Invention in Coupling Mechanism, of which the following is a specification.

This invention relates to coupling mecha" nism.

The object of the invention is to provide a coupling mechanism for coupling tractors and trailers, cars or the like, which is simple in structure, efiicient in operation and economical of manufacture.

A. further object of the invention is to provide a coupling device which is especially adapted for use in connection with motor truck tractors and trailers.

Further objects of the invention will ap pear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawing:

Figure 1 is a view in side elevation of a tractor and trailer employing a coupling mechanism embodying my invention.

Fig. 2 is a view in front elevation of a coupling mechanism. 7

Fig. 3 is a view in side elevation of the same.

Fig. 4 is a sectional view taken on the line A--B, Fig. 2.

Fig. 5 is a similar view taken on the line OD, Fig. 2.

Fig. 6 is a similar view taken on the line EF, Fig. 7.

Fig. 7 is a plan view of a modified structure embodying my invention.

Fig. 8 is a view in front elevation of the operating links employed in the modification shownin Fig. 7. v

Fig. 9 is a side elevation of the construction shown in Fig. 7.

The same part is designated by the same reference numeral wherever it occurs throughout the several views.

In Figs. 1 to 5, inclusive, I have shown my invention as applied to a motor tractor and trailer, wherein I provide a member 10 pivotally mounted in bearings 11 which are carried by the tractor. The member 10 is Specification of Letters Eat-ant.

Patented ha. is, rare.

Serial No. 115,243.

provided with a chamber adapted to receive a plunger 12 therein. The plunger 12 is pivotally connected to swivel plate 16 by a pin 17, to which said plunger 12 is connected by pin 18 as shown. The plate 16 is carried by the trailer. A shock absorbing pad 21, may be placed in the bottom of the menr ber 10 to receive the lower end of the plunger 12 as shown in Fig. i.

Springs 19 are interposed between the plate 16 and member 10 to absorb or retard the shock or movement of the tractor and trailer relative to each other.

The main portion of the plunger 12 extends into the chamber of member 10, and is provided with an annular groove 15. The member 10 has formed as a part thereof a casing containing the spring 14: which normally presses a collar 51 forming part of a bolt rod 13, toward the hollow chamber of member 10, thus pressing the ends'of the rod 13 into the annular groove 15 of the plunger 12, and to retain the same in the chamber of member 10, but at the same time allowing free swiveling movement of the plunger therein. From this it will be seen that I have provided a coupling mechanism which is exceedingly simple in structure, efiicient in operation, and which may be cheaply manufactured, being made of but a few standard parts.

The rod or bolt 13 may be operated in any desired manner. In Fig. 1 I show a simple arrangement where the coupling device is employed in connection with a motor truck and trailer. T designates the motor truck and P the trailer. Pivotally mounted on the truck Tis a bell crank lever Q, one arm of which is provided with a hook portion A, and the other arm of which is loosely connected to bolt rod 13, by the connection R. The trailer P is provided with a pin or lug S, over which the hook A is adapted to fit. To join the tractor and trailer the tractor is backed up to the trailer, the front end of the latter being held in sufiiciently raised position, and in any suitable manner, such, for instance,ias set forth in my Patent No. 1,179,793,'issued April 18, 1916, thereby causing the plunger 12 to clear the top of the member 10. The lever Q is then dropped so that the hook A engages the pin S, the arm R thereby withdrawing the bolt 13 and by starting forward the tractor, the lever Q draws the (ill trailer jorward with it, thereby releasing the front end of the trailer from the supportwhich maintains it raised, as explained in my said patent, and allows the plunger 12 to descend into the chamber of member 10. The lever Q, then may be raised to allow the bolt 13 to engage the annular channel 15 of the plunger. To further facilitate the reception of the plunger 12 in the member 10, the end of the plunger may be beveled as shown best in Fig. 4, thereby insuring a proper insertion of the plunger in the chamber of member 10.

lhe withdrawal of the rod 13 from out of the hollowmem'ber 10 may also be accomplished from the operating end of the vehicle T in any desired or well known manner. 1 show a simple arrangement wherein a rod is connected to the member R and to a foot pedal pivotally carried by the body of the vehicle T. It will be understood, however, that my invention, in its broad scope, as defined in the claims, is not to be limited or restricted in this respect.

In Figs. 6, 7, 8 and 9, I show a modified structure embodying my invention, and one which may be readily applied to trains or the like. In this arrangement the bearings 11' which support the member 10 are carried by one car and the plunger 1'2 is carried by the car to be coupled. I prefer to-employ two bolts 13 operated simultaneously from a common point. .To accomplish this I provide yokes 25, one for each bolt 13, engaging the same as shown. The yokes 25 are pivotally carried by brackets 26 secured to the bearings 11. The outer ends of the yoke members are pivotally connected to the links 27, which links are likewise pivotally connected to each other by comparatively shorter links 28; The links 28 are secured to a handle R at their approximate middles. Thus it will be seen that when the handle R is turned in either direction, the links 28 are moved thereby pulling toward each other the links 27, and the yoke members 25, thereby withdrawing the bolts 13 from the annular channel 15 oi": the plunger 12. I

Having now set "forth the objects and nature of my invention, and having shown and described various embodiments thereof, what I claim as new useful, and desire to secure by Letters is," 1.
