WILLIAM SHERMAN LEE, OF MYSTIC, IOWA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 735,888, dated August 11, 1903.

Application filed May 18, 1903. Serial No. 157,693. (No model.)

To aZZ whom it may concern:

Be it known that I,WILLIAM SHERMAN LEE, a citizen of the United States, residing at Mystic, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Car-Couplers; and I. do declare the following to be a full, clear, and exact description of the invention, such as will en-' able others skilled in the art to which it appertains to make and use the same.

This invention relates to car-couplers, and particularly to the Janney type of coupler.

The object of the invention isto provide a car-coupler of this character which may be readily uncoupled from the side of the car and which will automatically couple when brought into engagement with the coupler of another car.

A further object is to provide a coupler of this character which will be simple in construction, strong and durable, and well adapted to the use for which it is designed.

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

Figure 1 is a side elevation of the coupler, showing the same applied. Fig. 2 is a top plan view of the same, showing the parts closed. Fig. 3 is a similar view showing the coupler open or in position to be coupled. Fig. 4 is a longitudinal vertical section on the line 4 4 of Fig. 2. Fig. 5 is a horizontal section on the line 5 5 of Fig. 1. 6.is a cross-sectional view on the line 6 6 of Fig. 3. Fig. 7 is a similar view on the line 7 7 of Fig. 3. Fig. 8 is a detail view of the coupling-jaw. Fig. 9 is a detail of the latch or detent. Fig. 10is a detail view of the trip dog or pawl. Fig. 11 is a detail view of the latch pin or lever.

In the drawings, 1 denotes the end of a car.

2 denotes the coupler connected to the car in the usual manner. The coupler 2 is of the J anney type, comprising a head 3, shank 4, and pivoted jaw 5. The outer or engaging end of the jaw 5 is provided with a horizontal slot 6, above and below which are alined vertical openings or holes. The said slot and holes are adapted to receive a link-and-pin coupling when coupled with a car not having a J anney coupler. The inner end of the jaw 5 is provided with a hook-shaped extension 7, the lower outer face of said extension having formed thereon beveled engaging surfaces 8 and 9, said surfaces being inclined from the upper ends of the extension toward the center and lower edge of the same, as shown in Fig. 8 of the drawings.

In the forward end of the coupler is formed a horizontally-disposed cavity 10, into which the inner end of the jaw 5 and the hooked extension 7 are adapted to be moved.

12 denotes a horizontally-disposed cross pin or shaft adapted to pass through the couplerhead at therear of the cavity 10, and on said shaft or pin is pivotally mounted a latch or detent 13, the forward end of which is adapted to drop into the path of outward movement of the hooked extension on the coupling-jaws 3 and to hold said jaws in a coupled position.

14 denotes a latch pin or lever which is adapted to work through a vertically-disposed slot or opening 15 formed in the top wall of the coupler-head. The lower end of the lever or pin 14 has formed thereon a laterally-projecting cylindrical lug or stud 16, which is adapted to engage ahole or opening formed in the side of the latch or detent 13 in advance of the pivoted connection of the same. On

the rear side of the lever 14 is formed a shoulder 14 which is adapted to engage a shoulder or offset formed in the slot or opening 15 to lock said pin against casual upward movement when in its lowered or dropped position,

thereby holding the latch or detent 13 down and the jaw in coupled position. In the upper end of the lever 14 is provided an eye or opening, to which is pivotally connected a link member 17 ,havingrearwardly-proj ecting ears 18, between which is pivoted the upper end of the lever14, and an eye 19, arranged in front of the ears 18. A horizontally-projecting flange 20 is arranged on one side at the lower edge of the link, and when the lever or pin is down and the shoulder 14 thereon engaging the stop-shoulder in the coupler-head the flange 20 is adapted to rest upon the top of the coupler-head in such a position as to cover the slot in said head, and when in such position the forward end of the link is adapted to engage a nose or projection 17 on the couplerhead, thereby preventing accidental raising of the pin or lever 14.

21 denotes a pawl or dog pivotally mounted upon the shaft 12 in juxtaposition to the latch or detent 13. On the dog or pawl 21 are formed shoulders 22 and 23,which are adapted to engage the opposite ends of a flange or projection 24, formed on the contiguous face of the latch or detent 13, at points above and below the pivotal connection of the same, so that when the latch is raised by the lever let to release the coupling-jaw one end of the flange 24 will engage the shoulder 22 on the dog and rock the point of the same forwardly and upwardly into the path of the beveled face 8 on the hooked extension 7 of the jaw, so that as the jaw is swung outwardly in the act of uncoupling the said beveled face 8 will engage the point of the pawl, forcing the same downwardly, which will cause the shoulder 23 on the dog to engage the opposite end of the flange 24 and force the latch downwardly, causing the same to fall upon the top of the hooked extension of the coupling-jaw in such a position that as soon as the jaw is pushed in by the act of coupling the latch will drop in front of the end of the extension 7 and hold the jaw in. If for any reason the latch should become raised again after the jaw had been turned out, the beveled surface 9 of the extension would engage the point of the pawl on the backward movement of the jaw, which would rock the same and cause the latch to fall upon the extension, as before described.

25 denotes a horizontally-disposed shaft journaled in hearings on the ends of the car. The inner end of the shaft is provided with an angularly-bent arm 26, connected at its outer end to the eye 19 on the link member 17 by a short chain or other flexible connection 27. The opposite end of the shaft 25 extends to the side of the car and is provided with an angularly-bent curved arm or handle 28, which is adapted to normally hang downwardly against the end of the car, as shown. lVhen it is desired to uncouple a car, the arm or handle 28 is raised, thereby rocking the shaft and drawing up the latch pin or lever and raising the latch, as .hereinbefore described, thus permitting the jaw to be swung outwardly and the cars uncoupled.

29 denotes an opening formed in one side of the coupler-head to accommodate the end of the hooked extension of the jaw when the same is moved inwardly, and 30 denotes a projection formed on the side of the coupler above the opening 29 and is adapted to cover and protect the projecting end of said hooked extension.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inventi on 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 fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a car-coupler of the class described, the combination with a coupler-head, of a coupling-j aw pivoted in the outer end of said head, a latch or det-ent adapted to hold said jaw in a coupled position, a lever connected at its lower end to said latch or detent and adapted to be pulled upwardly to raise said latch, means for locking said lever against casual upward movement and means for releasing and raising the same, a dog or pawl pivotally mounted in said coupler-head, means carried by the inner end of said jaw, whereby upon movement of the same the said pawl or dog will be actuated and caused to engage and lower said latch to a position where it will automatically engage the inner end of said jaw when coupled and hold the same in that position, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- DQSSGS.

WILLIAM SHERMAN LEE. W'itnesses:
