CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 605,624, dated June 14, 1898. Application iiled December 20, 1897. Serial No. 662,639. (No model.) I

`.To a/ZZ whom, it may concern,.- lBe it known that I, JOHN F. BALL, Jr., a

citizen of the United States, residing at Turtle Creek, in the county of Boone and State of West Virginia, have invented a new and useful Car-Coupling, of which the following is a specification. v

The invention relates vto/improvements in car-couplings. p

The object of the present invention is to improve the construction of car-couplings and to provide a simple,`inexpensive, and eicient one capable of coupling automatically and adapted to be readily uncoupled without necessitating a person going between cars and guiding the link by hand.

The invention consists in the construction and novel combination and. arrangement of parts, as hereinafter fully described illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a car-coupling constructed in accordance with this invention and shown applied to a car. 'Fig.,2 is a longitudinal sectional View showing two draw-heads coupled. f Fig. 3 is a detail perspective view of the linkbar.

Like numerals of reference designate'v corresponding parts in the several gu'res of the drawings. r

1 designates a draw-head mounted on a car v2 in the usual Inanner and provided with a coupling-pin perforation 3, receiving a coupling-pin 4, which is pivoted to and carried by a lever 5, disposed longitudinally of the drawheadr and `fulcruinedr at its rear end thereon.

The rear end of the lever ispivoted in a` bracket or support 6 and is provided with an upwardly-extending arm 7, having a lug 8 anden gaged by'a spring 9, whichbears against the lug and holds the coupling-pinin engagenient with a link-bar 10. The lug 8 extends rearward from the arm 7, and the spring which is secured uponjthe draw-heads is adapted tohold the lever normally depressed."

The coupling-pin 4, which is prov-idedat its top with a bifurcated head, is pivoted to an ear of the lever at a point between the ends thereof and engages a perforation 11y of the link-bar 10.` The front end of the lever is ment with the link-bar.

' provided with a 'depending arm, forming a hook 12 and adapted to engage a lug 131of the link-bar The link-bar, which has its ends beveled, is provided at each end with a perforation 11 and a lug 13, and the latter is beveled at its outer edge and is adapted when the, link enters the draw-head to engage the front end of the lever and lift the same, whereby the coupling-pin is raised preparatory to automatic coupling. As soon as the 'front end of the lever passes over the lug it falls and the coupling-pin drops into engage- The inner edge of the lug forms astraight shoulder which is engaged by the hook of the lever, whereby the.

link is doubly locke/din the draw-head.

The draw-head is provided, in advance of the coupling-pin perforation, with an opening 14, disposed longitudinally of the top portion of the draw-head and extending inward from the outer end thereof to receive the hook 12, which has its terminal upturned at 15 in order to be readily engaged by the beveled lug 13.

lThe lever is provided between its ends with an upwardly-extending ear, to which is connected one end of a chain 16,`and the other end thereof is attached to a shaft- 17; but any other suitable uncoupling mechanism may be provided. The shaft 17 is journaled in suitable bearings'of the car 2 and provided with a crank-handle.

' The invention has the following tages:

rlhe car-couplin g, which is simple and comparatively inexpensive in construction, is automatic in its operation and does not require advanla person to go between cars and guide the link by hand.

The car-coupling is adapted to be readily uncoupled, `and there is no liability of the link becoming accidentally released from the draw-head, owing to the double locking action of the coupling.

Changes in the form, proportion, and minor details of construction'V may be resorted to without departing from the spirit or sacriicing any of the advantages of this invention.

1. In a carfcoupling, the combination .of a draw-head, a lever fulcrumed at its rear end Von the draw-head, a coupling-pin connected with the lever at a point between the ends of the latter, and a link provided between its ends willi n, lugr or projection arranged lo engage :1nd lift the lever, Suid link being' provided :it its ends beyond the lul;` with :in opening udzipted to receive the coupling-pin, substnntinlly :is described.

2. ln :t cur-Coupling, the combination olu draw-head, zt lever l'ulernmed at its reni' end on the draw-hemd, :t Coupling-pin eonneeted with the lever :it i point between the ends thereof, und u link provided between its ends with :i beveled lug arranged to lift the lever und interlocking` with the front end thereof, said link being provided it its end beyond the lug, with :1n opening ndnpted to receive the Coupling-pin, substantially :is described.

Il. ln :t cur-Coupling, the Combination of :t draw-bend, at lever fnlcrumed at its rear end on the draw-head und provided ut its front end with :L depending,` hook, :i coupling-pin Connected with the lever it :t point between the ends thereof, find n link provided willi :t beveled lng ndrlpted to raise thelever :1nd engagging thehook, said link being;` provided beyond the ln;r between the sume und its end with :t perl'ol'zttion to receive the couplingpin, substantially :is deseribed.

l. ln :t cnr-coupling, the Combination ol,` :t d rzuv-heztd, :i lever l'ulcrulned upon the slime :it its renr end und provided with :in upwardlyextending :trui lntving'nli1g,tl1e Vfront end of the lever being provided with :L hook, a eoupling-pin connected with the lever, t spring mounted on the draw-head and engaging the said lug, :1nd :t link provided with perforations and linvinf.,r lugs ndnpted to engage the said hook, substantially :Ls und for the pnrpose described.

In testimony that l clniin the foregoing :1s my own I have hereto alixed my signature in the presenee ot two witnesses.
