EAILVTAY DRAFT-RIGGING.

Sp ceification of Lettcrs Patent.

Application filed February 19, Serial Ito. 678,553. t v i To all whom it may concern: v

Be it. known that I, Ancrnn CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a. certain new and useful Improvement in Railway Draft-Elgging, of which the following is a full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in railway draft rigging.

The object of my invention is to provide a railway draft rigging of simple and cheap construction.

In the accompanying drawings, which represent the preferred way of carrying out my improvements, Figure 1 is a plan view partly in'horizontal section. Fig. 2 is a side elevation partly in vertical longitudinal section. Fig. 3 is an inverted plan View showing the opening through which one of the shock absorbing mechanisms is inserted. Fig. 4 is a cross section on line Jr-45 of Fig. 3. Fig. 5 is a side elevation of one of the draft members. Fig. 6 is a cross section on line 6-6 of Fig. 5. Fig. 7 is aperspective view of the sleeve.

. Referring to the details of the drawings represents the draw bar, the shank 8 of which is located between the draft members 9,.9. Extending rearwardly from the shank of the draw bar, and preferably integral therewith, is the hollow casing 10 closedat its rear end 11, and providedon itsunder. face with the opening 12 to permit the 1n= sertion. into the hollow casing in the as' horizontally extended to permit the movement of the draw bar in pulling action, and the slots 16, 16 in the draft sills are horizontally extended to permit the draw bar to move in buffing action. The key 15 is provided with suitable cotter pins 17 17, and carries within the casing 10 a suitable sleeve 18, the rear surface of which 19 forms a bearing for the forward end of the shock absorbing mechanism 13. The

rear end of the said" against theend 11 of the casin The draft members '9,

parallel sides

20, 20 between which the shock absorbing mechanism is sustained, the said sides being curved inwardly at their top and joining in the web 21, which is surmounted by the flange 22. The draft members extend rearwardly to the body bolster 23, and are suitably attached to the single center sill 24, though it is apparent that the said draft members may be readily attached to double center sills.

The side faces of the draft members near their rear ends are joined together at both top and bottom by the preferably integral members 25 and 26 forming the pocket or recess 27, which is closed at its rear end by the preferably integral plate 28, the said pocket containing a shock absorbing mechanism, preferably the spring 29, which bears at its rear end against the closed end 28 of the pocket, and bears at its forward end against the rear end 11 of the casing 10. The rear end of the draft members 30 rests against the front end of the sills of the car, and the front face 31 of the body bolster, and is'secured tothe body bolster by the rivets 32, 32 passing through suitable flanges 33, 33 provided at the rear end of draft members, and through the said bolster and center sills.

, It will be apparent upon buffing action of the gear, the rear end 11 of the casing 10 on rearward movement compresses the shock absorbing mechanism 29 withinthe pocket 27, and on pulling movement the forward travel of the draw bar will compress the shock absorbing mechanism between the rear end 11 of the casing and the sleeve 14. upon the key 15.

I claim 1. In a railway draft rigging the combination with the draw bar and means for supporting the same, of draft members and a .shock absorbing mechanism between said draft members, a hollow casing secured to the draw bar springs within said hollow casing, a key passing through said casing and slidingly engaging the draft members, the said draft members have their side faces joined together at the top and bottom form- PatentedSept .30,1913,

2. In a railway draft riggingthe combination with the draft members and draw bar, of a hollow casing secured to the draw bar, a spring Within said casing}. a key passing through said casing and slidably engaging the draft members, a pocket between said draft members, a spring within said pocket, the said spring being seated at its forward end against the said easing.

3. In a raiiwz draft rigging, the Combination with a draw bar and draft mem bers, of a pocket formed by said draft members, a spring Within said pocket, a

casing secured to the draw bar, said casing being in engagement with saidspring, a 15 spring within the casing, a key passing through said casing and siidably engaging the draft members, a sleeve mounted upon said key within the casing and forming a seat for one end of the spring Within the 20 casin ARGYLE CAMPBELL.
