CAR-COUPLING.

SiPECIPICATION forming part of Letters Patent No. 303,241, dated August 5, 1884.

Application iiled April 26, 1884. (No model.)

To @ZZ when?, t may concern:

Beit known that I, WALTER TURNEULL, a citizen of the United States, residing at New Orleans, parish of Orleans, and State of Louisiana, have invented a new and useful linprovement in Carcuplings, of which the following is a specification.

My invention relates to CaieGouplings which are operated automatically; and the objectsoi' 1o my invention are, irst, to provide a means by which railway-ca1s can be coupled together automatically, and without eiidangering the limbs and lives of railway employs; second, to aiiord facilities by which the cars can be I uncoupled either from the top of car or from the grouml, ad bibitem, and this end is accomplished Without.necessitating employs to stand on track between the cars, thus endangering their lives; third, to afford facilities 2O by which my ii'nproved automatic coupler can be adapted to any car, and be operated in conjunction with cars having other types of coupling. attain these objects by the meehanism illustrated in the accompanying drawings, in which f Figure l is an end view of freight-car showing the, application of my coupling. Fig. 2`is aside elevation of Fig. l. Fig. 3 is a plan view of the coupler. Fig. et is a horizontal 3D section showing `the coupling-pin in position to receive the link to be coupled. Fig. 5 is a horizontal section of the couple showing position of coupling-pin after the coupling has been made. Fig. 6 is an end view of coup-` ling.

Similar letters referto similar parts througl1 out the several views.

The buffer or draw-head D,With bell-mouth B, is supported between the (haft-timbers oi' 40 cars by the straps or plates P P, suspended from body of car by the bolts b i). At the rear end of draw-head D are placed or cast lugs L L", which keep draw-head from pull-` ing out by striking against the draft-plates i5 C C. These draftplates are secured bythe bolts Ai '15 to the draft-timbers of car. The drawhcad D is maintained in position and kept from being forced back under the car by the spring S, which is placed at rea-r of draw-head D, and between it and the Washer 5@ YV, secured to a heavy timber placed between the draft timbers of car, this spring S bef ing` maintained in position by the tongues t i, the object of the spring S, draftplates C and C', and washer W' being to provide a means 55 by which the draw-head D will have ela-s lticity, rendering the draw-head less liable to be injured and broken than if it were rigid.

The tongue or draw-bar T is secured to the draw-head, D by the pin N. The coupling- 60 pin u is secured to the forward end of drawbar T by the pin m.v To this pin m is secured a dog or automatic latch, G, provided with the shoulder H. This dog G straddles the draw-bar T, and passes through opening in bottom of draw-head D. Then the'eouplingpiu and draw-bar T are raised, the dog G rises also, and the shoulder H of the dog rests on the bottom of draw-head, and maintains the couplingpin in position to receive the eouplinglink. Then the couplinglink enters the drawhead D, it strikes against the dog G, knocking the shoulder H off from its bearing on bottoni of draw-head, which. allows the coupling-pin and draw-bar to drop and engage with the coupling-link. The link is kept from coming into the draw-head D too far by the back of dog G striking against the rib R, placed in bottoni of draw-head D. This rib R also forms a rest for the draw-bar SC T to rest on when the. coupling is made. The latch or dog G is kept from being pulled out` of slot in bottoni of draw-head D by the pin rv, placed in bottoni end of latch G.

The draw-bar T and coupling-pin a are raised by means of a chain or rope, K, at-

tached to the eyebolt o, placed in top end of the couplingpin u. There are threechains or ropes, K, attached to eyebolt o, one lead ing to each of the two levers E E, placed on 9o end of car, and Working on fulcruins Y, and one chain leading to bell-crank Z, placed on top of car, so that the car can be unconpled from either side or fronrthe top.

I am aware that prior to my invention carcouplings have been made to Work automatically. l therefore do not claim the subject, broadly; but

VhatI do claim its myinvention7 and desire `G, provided with shoulder H and piu x, :L11 to securev by Letters Patent, is* Substantially as Set forth ,for the purpose speci- The Combination7 in 2m automatic ear-eouped. 1er, of the drztw-head D7 provided with rib WALTER TURNBULL. 5 R, tongue t, and lugs L, With the draw-bar Vtnesses:
