CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 742,944, dated November 3, 1903.

Application filed July 20, 1903. Serial No. 166,256. (No model.)

To all whom it may concern:

Be it known that I, GEORGE WILEY, a citizen of the United States, residing at Vallejo, in the county of Solano and State of California, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification.

My invention relates to improvements in car-couplings, the object of my invention being to provide a car-coupling which shall enable the cars to be automatically coupled when coming together and which will enable this to be done also on a curve and which will be simple in construction and convenient in operation.

Myinvention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed outin the claims.

In the accompanying drawings, Figure l is a side elevation of two draw-heads having my improved coupling. Fig. 2 is a longitudinal section of the same. Fig. 3 is a broken plan view of the same. Fig. 4 is an end view of the same.

Referring to the drawings, 1 represents the draw-head, 2 the link sliding in the drawhead, and 3 the vertical coupling-pin in each draw-head.

4 represents a cylindrical casing or guide secured upon the top of the draw-head and guiding the pin. Over the hole 5 in the top of the draw-head through which the pin drops slides a bumper-plate 6, having a bumper 7 and an elongated hole 8 to permit the coupling-pin to drop therethrough when the bumpers are pressed back by bumping against each other.

9 represents a handle or lever pivoted at the base of the draw-head in a removable block 10, secured by countersunk screws 11, said lever passing through a hole 12 in the bumper-plate, so that by moving the lever forward the bumper may also be moved forward, so that its unslotted portion comes below the pin and serves to hold up the same, as shown on the right-hand side of Fig. 1. The pin is raised by means of a collar 13-, which surrounds the pin below a head 14 thereof, said collarhavingcrank-shaped arms 15,which extend through longitudinal or vertical slots 16 in the sides of the casing 4. The upper ends of said slots are curved around to form seats 7 for the arms 15 to rest in to hold the pin in its raised position when desired.

18 represents an outer casingrotatable upon the inner casing and closed at the top, said outer casing also having longitudinal slots 19, in which the arms 15 slide, the lower end of said slots being oblique, so as to throw the major portion of the slots 19 out of register with the slots 16 in the inner casing 4, thereby shutting off rain, snow, and sleet from said casing.

Fig. 1 shows the position of the draw-heads at the exact time when the bumpers have come together, but before said bumpers have been pushed back. In this position one of the coupling-pins already engages the link; but the other pin, that on the right in Fig. 1, rests upon the unslotted portion of the bumper plate and is therefore held up. When the bumpers are pressed back, the slot of the bumper-plate comes underneath the pin on the right, so that said pin drops through the second hole 20 in the link, thereby forming a link-and-pin coupling. When it is desired to couple upon a curve,the link is turned to one side or the other and is held in such oblique position by means of a dog 21, pivoted to the lever 9, the pointed end of which dog enters one of a series of notches 22 in the end of the link and holds said link to one side or the other. Holes 23 are also provided for pins 24, which are passed through the draw-head to limit the lateral movement of the link.

I claim- 1. In a car-coupling, the combination of the draw-head, the link therein, the pin, the easing for the pin mounted upon the draw-head,

the bumper and bumper-plate sliding upon the top of the draw-head, the latter havinga hole through which the pin can drop, and the lever pivoted upon the draw-head and operatively connected with said bumperplate, substantially as described.

, 2. In a car-coupling, the combination of the draw-head, the link therein notched at its innor end, the dog having a pointed end engaging said notches, the lever operating said dog, In Witness whereof I have hereunto set my the bumper-plate upon the draw-head euhand in the presence of two subscribing wit- 1o gaged by said lever and having a hole through nesses.

which the pin can drop, the pin having a 5 head, a collar around said pin below said GEORGE WILEY head and having arms, and a casing around Witnesses: said pin having slots through which said arms J 0s. J. BARTLETT,

extend, substantially as described. R. O. PIERCE.
