GEORGE MARSELLIS, OF MECHANIOSVILLE, NEW YORK, ASSIGNOR OF ONE- FOURTH TO JOHN UALEB GREEN, OF SAME PLAOE.

CAR-COUPL'ING.

SPECIFICATION forming part of Letters Patent No. 267,008, dated November 7, 1882.

i Application filed April 18. 1882.- (No model.)

To all n'hom it may conccrn:

Be it known that I, GEoRGE MAnsELLis, of the villa-ge of Mechanicsville, county of Saratoga and State of New York, have invented a new and useful lmprovement in Gar-Uouplers, of which the following is a specification.

My invention relates to apparatus designed to operate the usual link and pin by which cars are coupled, the object of my improveio ment being to produce a means by which the link may be `guided to enterthe draw-head and the pin inserted to hold the link there by the brakeman without his being compelled to pass between the cars.

My invention consists, as will hereinafter be more fully described, in the manner of constructing and arranging a pair of shear-arms having a tongs-clutch, with each of the arms pivoted to the car-floor, and also pivoted to zo each other by means of a slotted connection and shear-joint,so as to hold by and drop from the tongs-clutch the pin, together with a pivoted lever arranged beneath the car-floor at its end, which lever' is operated by a crank-` handle to guide thelink so as to enter the draw-head.

In the accompanying drawings, forming a part ofthis specification, there are three figures illustrating niy invention, in all of which the same designation of parts by letter-reference is used.

Figure 1 shows in perspective a view of the under side of the apparatus with the latter turned over and its under side npperinost.

Fig. 2 shows a view in perspecti've of the upper side of the apparatus. Fig. 3 shows a longitudinal Vertical section ofthe apparatus, taken on the line xx of Fig. 2.

The several parts of the mechanism consti- 40 tuting my invention and the parts of a carcoupling with which it connccts are indicated by letter-reference as follows:

The letters S' S' (lesignate the shear-arms, which are pivoted to the car-door or platform B at S2 S2, and also pivoted to each other by a slotted shear-connection at S3, so as to produce with their end jaws the tongs-clutch S4.

The letter O designates a U-form spring which is seonred to the car-floor or platform at G2, and the purpose of which is to keep the shear-arxns spread apart, and thus keep the tongs-clutch jaws closed around the couplingpin until it is desired to drop the latter into the draw-head D through the entering link L. This latter result is produced by pulling on either of the shear-arms S' S', which opens the tongs jaws and clutch and allows the pin to descend.

Theletter O indicates a U-forn1 lever which, at its side arms, a` little back of their center, is pivoted to the studs or standards d' d' at O2.

The letters A' A' designate two shafts which journal into the studs or standards dz at n, and these shafts have the cran ks A2 on their inner ends, which cranks connect with and work in the slots Oflforniedfin each side of the separated arms of th'e pivoted lever O. The cranks produced on each of the outer ends of these shafts `A3`A3 may be either of them used to operate the closed end of the lever O to elevate or depress it. v

Each end of the car being provided with the mechanisln above described, it is operated as follows: Byineans of either of the cranks designated at A3 (there being one at each side of the car) and the shaft which connects thein with the lever O, the outward end of the latter may be operated to rise up from beneath the coupling-link ot' the approaching car, so as to guide it horizontally to enter the draw-head So of the car to be connected. When this is done the brakeman, by pulling upon either of the shear-arms S' S', can release the pin, which willfall into thedraw-head with its point down- Ward, pass through the entered link, and thus complete the coupling connection. V

The standards or studs d' are pivoted at 82, and the-other standards or studs designated at dz are likewise pivoted or jointed at e', so that should the end of the lever 0 be caught between the draw-heads of the .two cars and forced back by the momentum of the hacking train the connected parts will all swing back with the lever and. return with it toposition when the train moves forward.

One great advantage is attained by the use of my invention is the fact that it furnishes a safe method of operatinga wellknown means- ,of the shear'arms S'S', pivoted to the car platform or floor separately, and also pivoted to each other by means ot' a slotted shear-joint provided with jaws to prod nce the tongs-clntchl S4, and the spring O, arranged between the shear-arms, the whole constrncted and arranged to hold and release the coupling-pinin the manner herein described and set forth.

2. Ina car-coupling device,the combination of a U-form lever having its side arms each journaled to a jointed standard or hanger, and

slotted at each of its ends to receive motion from a crank-shaft journal working in said slots at each side,a crank-shaft upon each side ofsaid lever, having bearings in jointed standards or hangers, and a crank upon the inner end of each shaft, which journals into the ad` joining slot in said lever to actuate the latter, and motor-cranks upon the outer end of each crank-shaft, arranged to operate as and for the purposes set forth.

3. A car-coupling' device'consisting, in con]- bination, of a tongs-clutch act-uated by sheararms that are pivoted to the car platform or fioor and by a slotted shear-connection With each other, the spring O, arranged between the shear-arlns, the U-form lever O, the crankshafts A' A', having journals in jointed studs or hangers, the inner cranks, A2 A2, and the outer cranks, A3 A3, constructed to opexate as and for the' purposes herein set forth.

Signed at Troy, N. Y., this 14th (lay of April, 1882.
