CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No, 446,356, dated February 10, 1891.

Application tiled October 2, 1890.

To all whom it may concern,.-

Be it known that we, WILLIAM I. LANK- FoRD and JOHN E. LANKFORD, citizens of vthe United States, residing at Bedford Oity, in the county of Bedford and State of Virginia, have invented a new and useful Car-Coupling, of which the following is a specification.

Thisinvention relates to car-couplin gs; and the object of the same is to provide certain improvements upon devices of this character, all as hereinafter more fully described, and as illustrated in the drawings, in which- Figure l. isa plan view of a draw-head constructed in accorda-nce with our invention. Fig. 2 is a longitudinal section of two drawheads coupled together, taken on the line 2 2 Fig. 3 is a similar section showing the cam as operated to uncouple the two drawheads. Fig. et is a side elevation of the drawhead, showing the devices for uncoupling the cars. Fig. 5 is a longitudinal section showing our improved coupling as connected by a peculiar link to a draw-head of the ordinary construction. Fig. (i is a perspective detail view of said link. Fig. 7 is a plan view of a draw-head of slightly modified construction.

Referring to the said drawings, the letter O designates a car, beneath which is mounted in any well-known Inanner the open-topped draw-head D, and within this draw-head on a horizontal pin H is pivoted the couplingbar C', having an arrow-head A with a bev- The draw-head D has a web XV rising obliquely from its mouth, and this web is provided with a notch N at its center, through which the bar B passes, and in which it rests.

In rear of the web is pivotally mounted the cam M, having an operating-arm O on the outer end of its shaft, and from this arm lead chains Z to the top and the sides of the car, whereby the operator can raise the cam without going between the cars. When the cani is so raised,it either lifts the body of its own coupling-bar C', thereby disengaging its head A from the other draw-head, or it lifts the head A of the coupling-bar O of the otherdraw-head, as shown in Fig. 3, and disengages that head. In either case the cars are un- Serial No. 366,878. (No model.)

coupled by operating either cam, as will be clearly understood.

Then the cars are brought together to couple, the sharp-edged heads A first meet each other, and whichever one is lower causes its couplingbar C to pass beneaththe other coupling-bar. The lowermost coupling-bar progresses until its beveled front end E strikes the oblique web IV of the other draw-head, up which it rides. Passing over the upper end. of the web, the body of the coupling-bar O drops into the notch N with its head A in rear of the web and just above the cani M, When the cars are coupled, as shown in Fig. 2. When so coupled, it Will be seen that thelowermost co upling-bar sustains all the draft while the other coupling-bar stands above the head that is coupled in the web and holds it from becoming accidentally disengaged.

In Fig. 5 we have shown a link L, adapted to be connected by a pin to the ordinary draw-head now in use. For this purpose one end of the link has an eye of the construction of an ordinary link, While the other end has `the head Aof one of the coupling-bars C.

.I ust in rear of the head A this link is provided with an inclined face F, which when the link is coupled into an ordinary drawhead stands just in front of such draw-head and serves to guide the head of the approaching coupling-bar upwardly and over said ordinary draw-head, whereby the headA at the front end. of the link L is allowed to engage the notch N in the web IV of our improved draw-head. It will be obvious that the link Inust always pass under the coupling-bar O, because the latter cannot be connected to an ordinary draw-head.

In' Fig. 7 we have illustrated a draw-head having a notch and a coupling-bar of slightly different construction; but the operation is the saine. In this case instead of one notch course when another link ot this construction strikes and rides up the web W it raises the upper link, and it engages the notches N the same as above described. The operation of the uncoupling devices is also the same.

What is claimed as new is- 1. In a ear-coupling, the combination, with the draw-head havin g a web provided With an inclined front face and a notch through its body, of a couplingfbar mounted on a horizontal pivot in said draw-head in rear of the Web and resting normally in said notch, substantially as described.

2. In a car-coupling, the combination, with the open-topped draw-head D and Vthe rearwardly-inclined web lV therein, having" a notch N in its upper ec ge, of the connectingbar C', mounted-on a horizontal pivot through the draw-head in rear of said web and resting normally in the notch therein, and a laterallyenlarged headA at the front end of said bar, having a beveled under frontend, as and for the purpose set forth.

3. In a car-coupling, the combination, with a draw-head having a web provided with a notch in its Lipper edge, of a link having a' i of the web and resting normally in said notch,

the free end of said bar having a laterallyenlarged head, of a link L, having an eye at one end and a head A at the other end, and an`inclined face F upon said link between its ends, each and all substantially as and for the purpose hereinbefore set forth.

In testimony that We claim the foregoing as our own We have hereto affixed our signatu res in presence of two witnesses.

WILLIAM I. LANKFORD. JOHN E. LANKFORD.
