AUTOMATIC CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 545,305, dated August 27, 1895.

Application filed May 21, 1895- Scrial No. 550,146- (No model.)

To aZZ whom it Judy concern.-

Be it known that'we, WILLIAM PERSELL and REDMAN NEWLEE, of the city of Wellsville, county of Montgomery, State of Missouri, have invented certain new and useful Improvements in Automatic Car-Couplings,

of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to an improved automatic carcoupling; and it consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view of our improved coupling, the same being shown in its proper bearings and relative to the carbody. Fig. 2 is a longitudinal vertical sectional view taken approximately on the indicated line 2 2 of Fig. 1. Fig. 3 is a longitudinal sectional view taken approximately on the indicated line 3 3 of Fig. 1. Fig. 4is a vertical cross-sectional view taken approximately on the indicated line 4 l of Fig. 3. Fig. 5 is a rear elevation of a pivoted block located in the draw-head of our improved carcoupling. Fig. 6 is a view in perspective of one of the plates located upon the side and rear end of the draw-head. Fig. 7 is a view in perspective of a plate located on the rear end of the draw-head.

Referring by numerals to the accompanying drawings, 1 1 indicate timbers that are located upon the under side of the car-body, and the inner faces of said timbers are provided with metallic plates 2. Formed in these timbers 1 and plates 2 are horizontally-aligned slots 3.

& indicates the draw-head of our improved coupling, the same being constructed with a recess 5 in its rear end.

6 6 indicate metallic plates that are let into the sides of the rear end of the draw-head, and said plates are provided with notches 7 and longitudinal slots 8, that coincide with the slots 3, formed in the timbers 1 and plates 2. Tongues 9 are formed on the forward ends of said plates 6 and extend into recesses formed in the sides of the draw-head. The ends 10 of these plates 6 are bent inwardly and overlap each other, and said ends 10 are the link-recess 21.

provided with coinciding apertures 11 in'their centers and rectangular notches 12 in their top and bottom edges. A rectangular metallic plate 13 is provided with a centrally-arranged aperture 1 1, that coincides with the apertures 11, and said plate 13 is provided with laterally-projecting tongues 15, that extend through the rectangular notches 12. A plunger 16 is positioned within the recess 5 in the under side of the draw-head, and said plunger is constructed with a lateral projection 17, that passes through the aligned apertures 14 and 11 in the plates 13 and 6. A horizontally-arranged slot 18 is formed in this plunger that is in direct horizontal alignment with the slots 8 in the plate 6 and theslots '3 in the side timbers 1. A bar 19 is located in said aligned slots, and a coil-spring 20 is located upon the body of the plunger 16, between the bar 19 and the ends of the plates in the rear of the plunger. By this construction' slight longitudinal movement is allowed the entire draw-head.

Formed in the forward end of the drawhead is an ordinary link-recess 21, and passing vertically through the forward end of said head'is a vertical bore or passage 22, through which the pin passes. Passing vertically through the head directly in the rear of this aperture or passage 22 and to the rear of the link-recess 21 is a bore or passage 23, that communicates with a recess 24, formed in and extending upwardly from the bottom of the head of the draw-bar. Formed in said head on each side of this vertical passage 23 and communicating with the link-recess 21 and the lower face of the head are vertical recesses 25. The lower portions of the recesses 24 and 25 are formed into a single recess 26.

27 indicates a block the entire forward portion of which is bifurcated and formed integral with the walls formed by this bifurcation, and extending forwardly and upwardly is a pair of arms 28, that extend into the forward ends of the recesses 25, and a pin 29 is passed through apertures formed in the forward ends of these arms 28 and through apertures formed in the forward end of the draw-head above Thus said block and arms are pivoted in the recesses 24 and 25. Said block 27 is not wide enough to fill said recesses. Therefore it is capable of a slight vertical movement. A tongue or lug 30 is formed integral with the upper end of the block 27 and projects into the recess 24. A bar 31, having an inclined lower end 32, is arranged to move vertically through the vertical'passages 23, and formed integral with the upper end of said bar 31"is a block 33, that extends forwardly over the pin-aperture 22. Passing through the aperture formed in the forward end of this block 33 is a pin 34:, that passes through the vertical aperture 22. The block 33 is provided with an upwardly-extending lug 35 at its rear end, and a pin 36 is passed through said lug 35 and through the rear end of an operating-lever 37, that is pivoted to the end of the car-body in a plane slightly above the draw-head. I

The operation is as follows: Previous to makinga coupling between two cars equipped with our improved coupler the operator bears downwardly upon the outer end of the lever 37, and this movement raises the block 33, carrying the bar 31 and pin 34:. As the lower end 32 of the bar 31 passes above the body of the block 27 said block will fall to its lowermost limit of movement and the inclined lower end 32 of said bar 31 will rest directly upon the inclined forward face of the body of the block 27 and in the recess 24. The lower end of the pin 34. will, with this movement, have been drawn into the pin-aperture 22 above the link-recess 21. The coupler is now set and in position to receive the link carried by the coupler located upon the approaching car. Said link in the opposite coupler will enter the link-recess 21 in the usual manner, and in so doing will strike against the lower edges of the forwardly-projecting arms 28, and as said link moves rearwardly in the linkrecess 21 said arms and the entire block 27 will be raised in the recesses 2a and 25. As soon as said block 27 is raised a distance sufficient to allow the bar 31 to pass through the vertical aperture 23 said bar will, by reason of its weight and the weight of the block 33, drop to its lowermost position, and with said movement the pin 34: will pass downwardly through the pin-aperture 22 and through the link, which has now passed into the link-recess 21. Thus a coupling is effected.

To uncouple two cars equipped with our improved coupler the operator bearsdownwardly upon the outer end of the lever 37, and the block 33, carrying the bar 31 and pin 34:, is drawn upwardly. The link is now free to move out of the link-recess and the coupler is set to make the next coupling.

A coupler of our improved construction is entirely automatic during the act of coupling, is so arranged as that the operator does not have to go between the cars in effecting a coupling or uncoupling, and said coupler possesses superior advantages in point of simplicity, durability, and general efficiency.
