CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 555,430, dated February 25, 1896.
Application filed January 8, 1896. Serial No. 574,686. (No model.)
To all whom t may concern:
Beit known that I, JOSEPH WILLIAM CoL- BERT, a citizen of the United States, residing at Fredericksburg, in the county of Spottsylvania and State of Virginia, have invented new and useful Improvements in Automatic Oar-Couplings, of which the following is a specification.
This invention relates to that class of carcouplings having vertically-sliding gates for engaging conoidal or hemispherical heads on the ends of couplin g-pins in such manner that the cars automatically couple and are uncoupled by raising the gates thro ugh the medium of suitable levers.
The object of the present invention is to improve the prior construction of this class of car-couplings, and to provide a novel carcoupling and means for operating the same, whereby the cars will automatically couple and can be uncoupled by the engineer in the cab, or by the brakeman in the cars, or upon the tops thereof, or by a person standing on the ground at either side of the cars.
To accomplish this object my invention consists in the features of construction and the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a perspective view of a portion of a car provided with my improved coupling. Fig. 2 is a detail front elevation showing the draw-head in section, and Fig. 3 is a detail longitudinal sectional view of portions of two couplings embodying my invention and showing the position of the parts when two cars are about to come together.
In order to enable those skilled in the art to make and use my invention I will now describe the same in detail, referring to the drawings, wherein- The numeral l indicates a draw-head, which may be of any ordinary or other construction suitable for the purpose and be provided, if desired, at its mouth with ordinary couplingpin holes 2 for rendering the draw-head susceptible of use in connection with ordinary car-coupling links.
The coupling-pin 8 employed by me is constructed at each end with a conoidal, hemispherical or other similar-shaped head,which, when engaged with the draw-heads, rests in depressions 5 formed in the bottom walls of the draw-heads, as will be understood by reference to Fig. 3.
' The device for engaging and releasing the head of the coupling-pin to couple and uncouple the cars is composed of a verticallyslidable gate 6, approximately rectangular in outline and having its vertical edges arranged in and guided by vertical grooves '7A formed in the opposite sides of the draw-head. The upper end of the gate is constructed with lateral shoulders 8, adapted to rest on top of the draw-head when the gate is lowered, and the lower end of the gate is constructed with an approximately V-shaped notch, the edges 9 of which slightly diverge for a portion of their length and then abruptly and widely diverge at a greater angle of inclination to the vertical edges of the gate, as will be best seen by reference to Fig. 2, the construction being such that when the gate is in its closed or lowered position the body of the coupling-pin will lie in the top portion of the approximately V-shaped notch, and the edges 9 of this notch will engage behind the base of the pin-head, thereby making a positive connection between the coupling-pin and the drawhead, which it is impossible to separate unless the gate G be intentionally raised by the brakeman or other person.
The upper end of the gate 6 is slotted to form two parallel ears or lugs lO, between whichis arranged a cam-shaped head 12, pivotally mounted on the car-body through the medium of ashaft 13. The cam-shaped head 12 is constructed with a cam-shaped slot 14, through which passes a bolt or pin 15, which is secured to the ears or lugs 10 and extends from one to the other, thereby providing a pin-and-slot connection between the cam-shaped head and the gate for the purpose of enabling the latter to be raised whenever it is desired to un- 'couple the cars or to set the gate for the automatic coupling of the cars. The shaft 13 is mounted in suitable bearings secured to the end of the car-body, and the ends of this shaft are provided with cranks 16 or any other suit- IOO ably-shaped handles which are susceptible of being operated by a brakeman or other person standing on the ground at either side of the car.
The cam-shaped head 12 is provided on its upper edge with an eye 17, to which is loosely attached the lower end of a link 18, connected at it-s upper end to one end of a lever 19, fulcrumed in the slotted upper end of a bracket 2O and overhanging the top of the car, as will be best understood by reference to Fig. 1. The slotted bracket 2O is secured to the upper end of a vertical board 21, mounted on the end of the car-body, and the slotted part of the bracket is provided with a fulcrum-pin, as at 22. The lever 19 has its fulerum upon the pin 22, and when the lever is approximately horizontal, which is the position it occupies when the gate (5 is elevated, or set in position to automatically couple, the long arm or end portion of the lever is engaged by a spring-cate 23 and rests in a fork 24, located at a point between the fulcrumpin 22 and the spring-catch 23. The l'ork 2t is secured to the upper end 01": a vertically-movable leverreleasing slide 25, arranged behind and covered by the board 21 and having its lower end extending into the draw-head and constructed with an angular head 2G, having a beveled front face 27, against which the conoidal, hemispherical, orAv similar shaped head 4 ol' the coupling-pin 3 acts when the head of the pin enters the draw-head for the purpose of causing the slide 25 to rise, and thereby force the long arm of the lever 19 out of engagement with the spring-catch 23, whereupon the gate C will automatically descend by reason of the fact that the slotted cam-shaped head 2 is unsupported in its elevated position, and the weight of the gate and cam-shaped head causes them to fall by gravity, thus autom atically coupling the cars.
In order to permit a comparatively short spring-catch 23 to be employed, the long arm of the lever 19 is constructed with a downward1y-bent portion 2S, and to enable the long arm of said lever to be pulled downward and for uncoupling the ears 1 connect the bent end portion 2S of the lever with cables or cords 29, 30, and 31. The cords 29 and 30 pass over suitable pulleys or other guides mounted on the car-body and extend down the sides thereof, so that they can be manipulated by a brakeman or other person standing within, the car for uncoupling the cars from the inside of the car. The cable or cord 31 is designed to extend along the top of the ear to the end thereof or to the engineers cab, so that the engineer can uncouple the cars while standing in the cab.
The cable or cords 29, 30, and 31 are only intended to represent devices typical of many forms oi' devices which can be employed for moving the long arm of the lever 19 in a downward direction for the purpose of engaging it with the catch 23.
It will be obvious that when the long arm oi the lever 19 is moved downward the camshaped head 12 is swung upward, and the gate 6 is elevatedto set it in position for automatic coupling of the cars. When the gate is raised or set for automatic coupling, the beveled face 27 of the angular head 26 on the lower end of the slide 25 lies considerably below the notched lower end of the gate, so that when the head of the coupling-pin enters the draw-head it will strike the beveled face 7 of the head 2G and force the slide 25 in an upward direction, thereby forcibly disengagin g the bent portion 28 of the long arm of the lever 19 from the spring-catch 23. In my construction the head of the coupling-pin is so interloeked with the draw-head and the gate that the pin cannot accidentally uncouple, even though it be swung upward, or downward, or laterally.
rl`he slide 25 is guided in any suitable manneil at the rear of the vertical board 21, and I preferably reduce friction, incident to the vertical movements of the slide, by arranging it to move in contact with antifriction-rollers, as at which may be mounted on the board 21 or arranged in any other manner suitable for the purpose stated.
The coupling-pin is of such construction and dimensions that it will fall out et a drawhead if the gate enga-ging the pin at one end is raised and the other end of the pin is unsupported or is not engaged with the drawhead of an adjacent car.
It will be observed that in my invention the lever 19, which serves to operate the gate from the top of the car', is in operative connection with the cam-shaped head 12,n1ounted on the shaft 13, which latter enables the gate (i to be raised from either side of the car by a brakeman or a person standing on the ground. By this means it is possible to couple and uncouple, under all circumstances, withoutthe necessity of; the brakeman entering between the cars.
The draw-head will, in practice, be supported and made spring yielding in any ordidary or suitable manner; but as spring-yieht ing draw-heads of various construction are well known I do not deem it necessary to illustrate any particular arrangement of springs for enabling the draw-heads to yield when two ears come together.
In the drawings I have shown the link 1S pivoted to or loosely connected with one end of the lever 19; but I do not confine myseli1 to such connection of the parts.
In Fig. 3 of the drawings the couplingpin is shown engaged with the draw-head of one car and about to enter a draw-head having its gate raised and set for automatic coupling. NVlien the head of the coupling-pin en,- ters the draw-head, the pin-head strikes the beveled face of the angular head on the lower end of the vertically-movable slide, thereby forcing the latter upwardly, so that the fork ICO TIO
on the upper end of the slide raises the long end of the lever 19 from engagement with the spring-catch, whereupon the gate 6 falls by gravity and the two cars are automatically coupled. n
The cars can be uncoupled by the engineer through the medium of the cable or cord 3l, or by a brakeman standing on the top of a car, or by a brakeman standing inside of a car and operating either of the cables or cords 29 and 30, or by a person standing on the ground at either side of the car and operating the shaft 13.
It will be obvious of course that the cars can be uncoupled by directly manipulating the lever 19 without the employment of the cables or cords.
Having thus described my invention,what I claim is* 1. The combination with a draw-head provided with a pin-engaging-device, of a lever mounted at the top of the car-body, connections between one arm of the lever and the pin-engaging device, a catch for engaging the other arm of the lever, and a verticallymovable slide operated by a coupling-pin entering the draw-head and acting to disengage the lever from the catch, substantially as described.
