CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 566,650, dated August 25, 1896.

Application filed June 5, 1896. Serial No. 594,894. (No model.)

To all whom it may concern:

Be it known that I, PHILIP BOGLER, of Alamosa, in the county of Oonejos and State of Colorado, have invented new and useful Improvements in Oar-Couplings, of which the following is a full, clear, and exact description.

This invention relates to car-couplings of the drop-pin and link type, and has for its object to provide novel features of construction for a car-coupling of the indicated char acter which will adapt the same for effecting an automatic coupled connection with a similar coupling and that will permit the safe and convenient detachment of two couplings at the sides of the cars.

The invention consists in the novel construction and combination of parts, as is hereinafter described,and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side view of the front portion of the improved car-coupling, showing parts thereof adjusted to support an uncoupled link and coupling-pin. Fig. 2 is a sectional side View of the parts shown in Fig. 1, showing the pin dropped and the link coupled to the draw-head 5 and Fig. 3 is a front end view of the coupling draw-head broken away, a dropped pin in the draw-head, and a pin-lifting device shown broken intermediately and in position on the end of the car shown in part.

The draw-head 10 is preferably cast into form from suitable metal, and the draw-bar 11, integrally formed with the draw-head, in completed condition is adapted for a suitable attachment on the car A at its ends. The draw-head 10 is chambered, as at o, and open at the front end, that is furnished with the fiarin g throat-walls l) to adapt said draw-head for the convenient insertion therein of the elongated coupling-link 12. Preferably the throat-walls Z) are in the form of inclining flange walls, rounded on their free inner edges, said edge on the lower flange-wall affording support to the link 12 when it is introduced within the chamber a.

An essential feature of the invention consists of the peculiarly-shaped gravity-block wardly, thus producing an open recess 6,

wherein the end of an inserted link 12 will enter, and, as shown in Fig. 1, when the link is fully inserted and the gravity-block forwardlyrockedin its normal position the swell e that is above the toe (Z on the block 13 will contact the lower portion of its defining wall with the upper side of the link at its inserted end and hold the link in a level condition.

From the upper end of the gravity-block 13 a table-flange g is forwardly extended, and, as shown in Fig. 1, the front edge of said table-flange contacts with the upper throatflange Z1 when the gravity-block is in its normal position or forwardly rocked to admit the end of a coupling-link in the open recess 6.

The top and lower walls of the draw-head 10 are perforated, as at f f, in the same Vertical plane at the transverse center of the drawhead, for the loose insertion of the cylindric coupling-pin 14, that has a headed enlargement h on its upper end, to which a flexible connection 15 is secured by one end, having its opposite end attaohed'to the outer extremity of a rock-arm 16, that projects from the rock-shaft 17. The lower perforation f is cupped or countersunk to insure the passage of the pin 1a through the lower wall of the draw-head when dropped, and an adjacent hole f is formed behind the hole f to permit the escape of snow or water.

The shaft 17 is journaled on the end wall of the car A, and is provided with a handle 71 at each end, and the length of the shaft slightly exceeds the width of the car-body whereon it is placed in a level condition, so that the handles z'will be operative from the sides of the car by a trainman 0n the ground.

The table-flange g is perforated at a point 9, which will permit the pin let, that rests on the flange named when the gravity-block 13 is forwardly rocked, to pass loosely through pin from the draw-head is prevented, .as

said table-flange when the gravity-block is pressed upon at the front by a forcible insertion of the link 12, that impinges said block in the recess e, as clearly shown in Fig. 2. It will be seen that the tendency of the gravity-block 13 to incline forwardly rests the rear edge of the perforation "in the tableflange g on the body of a dropped pin 12, and thus prevents said pin from being jarred-out. of a correct vertical position while in service. There is a guard-chain 18, attached by one end to the draw-head 10 and at its opposite; end to the head of the pin 14, having such length as will permit the'correctelevation ofl said pin, while the upward removal of the I shown in Fig. 1. E It will'be evident from "the foregoing tie-2 scription that the elevation of the pin 14 :Joy

means of the rock-shaft 1 7, as (before ex plained, will :allow the gravity-block 13 vto? automatically rock forward until its front? edge strikes the top zthroat-flange b, which arrests said block, thus :affording'atable .onj the flange ;g for the pin to rest on; and it; will be-seenthat the'weight of the .pin, ito-i gether with the heft ofthe block ,13 that isf 'now disposed forward of the pivot c, willre-f tain an inserted-link 12 leveland loutwardl-yl projected from .the drawehead:toaentera simii lar draw-head.

When thereare two'of the improved car-l couplings onzcars that are to be coupled byi a link 12, the link may be :eitherzplacediin one l draw-'headand left uncoupled, as ,shown in? Fig. 1, or be coupled by dropping the pin, as in Fig. 2. In either case the link will be held projected by the gravity-block 13 to enter and rock a similar block in a like drawhead, and which has been adjusted to support the pin 12 on the table-flange g, the rearward movement of the table-flange on the impinged block dropping the coupling-pin and effecting an automatic coupling of the two cars having the improvements.

Having thus described my invention, I claim :as new and desire tosecure by Letters Patent- "The combinat'ion with a chambered drawhead that is perforated in its top and lower Walls near the'front end, andan elongated coupling-link, of aagravity-block pivoted in the chamber of thedraw head Fnearthe lower edge of "the block, said iblOCk having 'a forwardly-extended itoe, :a transverse open re- :cess ilnmediately-above'the toe, a forwardlyprojecting swell above the recess, affording an overhanging Wall that contacts with the end-of the link when th'eflatter rocci pies'the recess, the :blockibeing'f urther provided with a forwardly-projecting table-flange, that is perforated to drop El'ihG pin when the block is rearwardly "rocked,.and adapted to sustain said pin at "the :rearof sthe sperforation when the'block -is forwardly rocked, substantially as described.
