lT'o' all 'rtuhbm it'may concern:

Be it knownthat I, CHARLES A; GILMORE,-

acitizen of the United States, residing at :McComb, inthecounty of Pike and State ofw-Mississi p'i,-have invented certain new anduseful mprovements in DrafteGe'ar, of

which thefollowing is a specification.

My invention relates to coupling mechanism to. be "used in connection with railway =cars.-- I

or'tant' object of this invention is to' provi e a-coupling mechanism, embodying a yielding m'ember,;so that the car to which the mechjani sm is attached will re- 15. eaves minimum amount of shocks or jerks,

when-being coupled to another car, or when being set in motion from a state of rest.-

A vfurther objectof my invention is to provides device of the character described, ada-pted t0 fulfilthe double function of a coupler mechanism and bufier.

A. further object of this invention is to provide a device of the above character, 4 avlng a simplified structure, which is posifive-and reliablain-opewtion.

' Othenobjectsjand advantages of this invention'will-be apparent during the course,

of the following descri tion.

In the accompanyin drawings forming a" partxof this specification and in which like numeralsa're employed to designate like parts throughout the same,

Figure lis a. plan; viewof the coupler mechanism, Fig. 2 isatzcentral longitudinal section .therethrough, Fig. 3 is -a transverse vertical section, taken'on line 3-3 of Fig. 2, Fig.4 is a similar view, taken on line H of Fig. 2, and Fig. 5 a central longitudinnsecti'onthrough i the-draw-bar casing,

540 other members of the coupling mechanism being removed for the? sake of 'elearness.

In thedrawings wherein is illustrated-,a preferred embodiment @bf-my invention, the numerals-6 and 7 designate transverse end beams of a railway car having connections with central longitudinal beams 7". To the transverse endbeams is secured the outer end of a draw-bar casing 8, having upstanding flanges 9 and 10 engaging respecti ely the transverse eams 6 and 7,a s ow11- The flange? is rigidly connected with beams 6 andj'l, by truss rods 11, extending-longitudinally of the car and having connections therewith, in the usual manner. The top wall of-the draw-bar casing 8 is extended at its inner end, as shown at'12',-and has Specification of Letters Patent.

connections with a transverse beam 13,by

means of bolts 14. The side walls of the casing 8 are provided near their centers with spaced longitudinal slots 15 and 15 formed therethrough, as clearly illustrated in Fig. 5, which'register with pairs of slots 7 formed through the beams 7. The lower wall of the casing 8 is preferably formed open, as shown, and the ends of the side walls of the casing 8 are connected by trans- 17.- The extension 12 of the upper wall is rovided with a pair of oppositely extending ears 18, which engage the truss rods 11; as clearly shown in Fig. 1.

' -Mounted within the draw-bar casing 8, is' a hollow draw-bar 19, which is capable of moving longitudinally within said casing This hollow draw-bar is provided with 2. preferably, cylindrical axia opening 20, as shown. The side walls of the draw bar 1?), are provided with pairs of spaced longitud1- nally disposed slots 21 and 21* adapted for registratlon respectively with the slots 15 and 15 formed through the side walls of the draw-bar casing 8. A web or section of mate- 'rial 22 surrounds the inner slots 2-1 and 21 of the draw-bar 19, as shown in Figs. 2 and 3. Transverse bars 23 and 23'1 are disposed respectively within the registering slots 15, 21, 15 and 21 and normally ccupy positions adjacent the outer end wills of these slots. These transverse bars engage circular head's 24, which are disposed in tween the same, as shown. In orderto obtain "an elastic member having a desired degr ee of stillness,'I preferably employ a pair of compressible coil springs 25, one of which is disposed within the other, as shown in Fig.

2. These compressible springs are arranged within the hollow draw-bar and disposed between and for engagement with the heads 24. The heads 24 are provided with reduced inwardly extending portions 26,? disposed within the axial opening of the smaller inner spring 25, and firmly gripped bythe same for holding said heads 24 in permanentenga ement with the-springs 25. "The outer en of the draw-bar 19 carries a -coupler head 27 of any preferred or well known type, having an upper lip 28 which engages flange 9 when the draw-bar is in its innermost position. i

In the use of my coupling mechanism, when the draw-bar 19 .is moved inwardly,

which is efiected when "two cars are being Patented J an. 9,

verse strips 16, bolted thereto, as shown at coupled the inner transverse bar 23 re-.

mains in its normal position adjacent the: outer end walls 15* of the slots 15" and forms a stationary abutment for the springs 25. The outer transverse bar '23 is moved'inwardly from the outer end walls l5 of the slots 15, and remaining in engagement with the outer end walls21 of the outer slots 21, engages the springs 't0 com ress the same against the inner transverse er Q33 g-flhe draw-bar is thus first yieldingly retarded in its inward movement. This inward movement is stoppedwhen the 1ip 28 engages the flange 9 o the casin 8. When the carshave been coupled, an their travel from a state'of rest, the draw:

bar ,19 is first moved'longitudinally in an. outward direction. During this outward movement of the draw-bar, the-outer transverse bar 23 remains in engagement withthe outer end walls 15 of the outer 'slots 15 and thus serves as a stationary abutmentfor the springs 25. The inner transversebar 23 remains in engagement .withthe. inner {end-,-

walls 21* of the inner slots 21 and travels walls; engagmgthe outwardly with said end sgrings 25 and compressing the same. against t e now stationary outer transverse bar-23.

The draw-bar 19 1S thusyieldingly. retarded.

the same started in during its. outward movement. This out- .ward movementof the draw-bar is stopped when the inner end walls 21" of the outer slots 21 engage the outer transverse bar 23 and the inner transverse bar 23 engages the inner end walls 21" of the inner slots 15.
