reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to improvements in 1 draft rigging for railway cars.
The object of my invention is to provide a draft rigging of high cushioning capacity both in buff andin draft.
In the drawings forming-a part of this specification Figure 1 is a side elevation partly in vertical longitudinal section on line 1 -1 of Fig. 2 of a draft rigging embodying my invention. Fig. 2 is a plan view partly in horizontal section on line 22 of Fig. 1, and showing the parts in normal position. Fig. 3 is a plan view partly in horizontal section showing the'position of the parts of the draft gear when fullycompressed in buif. Fig. 1 is a cross section on line 4- of Fig. 2, one side, how ever, having the spring cap removed. Fig. 5 is a plan view partly in horizontal section showing the position of the parts when fully compressed in draft. 1
Referring to the drawings, 6, 6 represent draft sills or the parts of the car frame to which the draft rigging is applied, said ldraft sills being provided with rear stop shoulders, '7, 7 and front stop shoulders 8, 8; 9' designates the end sill, 10 the draw bar carry iron, 11 a tie-plate suitably secured to the draft sills, 12 a draw bar, 13 the draft yoke secured to the draw bar, 14 draft gear mounted between the draft sills and within the draft yoke. The front follower 15 engages the front stop shoulders 8, 8, the stop shoulders being extended inwardly from the opposite faces of the draft sills leaving between them a suitable space for the passage of the draw bar and draft yoke. The draft gear 14 comprises an inner shell 16 and outer shell 17 inclosing the inner shell, main springs 18, friction mechanism 19, an internal follower 20, a key 21 and a preliminary spring 22. I Y

closed at its rear end by the preferably inprovided at its rear end with lateral outwardly extending wings 24, 24- which performthe functions of a rear fol-lower and are adapted to engage the rear stop'shoulders 7, 7. The friction mechanism 19 is mounted within the inner shell and consists of the friction shoes 25 which are preferably three in number and adapted to engage the internal friction face 26 of the inner shell, 21 wedge 27, having wedging faces 28, said faces equaling in number the friction shoes,
there being an anti-friction roller 29 interposed between each wedging face of the wedge and the adjacent friction shoe. The Wedge 27 forwardly engages the front follower l5 and is provided with a recess 30 to receive the head 31 of the connecting rod 32, the
said connecting rod engaging at its rear end the internal follower 20, the samebeing provided with a recess 33 to receive the nut 34 of said'connecting rod.- Theinternal follower 20 is forwardly provided about its outer edge. with a collar 35 within which is mounted the preliminary spring 22, the same being seated at its forward end againstthe friction shoes 25 and at its rear end against the internal follower 20. The key 21 passes through the transverse slot 36 in the internal follower and through slots 37, 37 in either side of the inner shell, said slots 37 being rearwardly extended to permit the sliding of the key 2l-therein on rearward movement 0% tlllie internal follower relative to the inner s e The outer shell 17 is preferably cylindrical in shape and is secured to the internal follower 20 by means of the key 21 which is connected at either end to the outer shell, preferably engaging within slots 38, 38 in the outer shell registering with the slots 37 in the inner shell. Laterally extended from v the forward end of the outer shell are the wings 39. 39 at either side. The main springs'18, 18 are mounted at either side of follower 20 until the collar 35 thereof engages the friction shoes 25 whereupon the internal follower 20 moves rearwardly drawing rearwardly the outer shell by means of the key 21, thus compressing the main springs between the wings 39 of the outer shell and the wings 24 of the inner shell, the springs meanwhile resisting the inward movement of the friction shoes and the wedge spreading said friction shoes. During the rearward movement of the draw bar the inner shell is stopped by its engagement against the rear stop shoulders 7, and the key 21 slides rearwardly in the slots 37, 37 in the said inner shell.
Upon forward movement of the draw bar the friction mechanism engages the front follower 15 which is stopped by the front stop shoulders 8, the draft yoke draws the inner shell forwardly, the pressure of the main springs between the wings 39 of the outer shell and the-wings 24 of theinner shell holding the key 21 against the forward ends of the slots 37 in the inner shell while the preliminary spring 22 is compressed, whereupon the internal follower engages the friction shoes. During the compression of the preliminary spring the inner and outer shell travel forward together. After such compression and the engagement of the internal follower against the friction shoes the v inner shell travels forward at a greater rate than does the outer shell. The friction shoes are brought into action as they are spread by the wedge against the internal friction faces of the forwardly moving inner shell and resisted by the compressing main springs until on full compression in pulling movement the parts assume the position illustrated by Fig. 5 of the drawing, the key 21 engaging the rear ends of the slot 37, and the front end of the inner shell engaging the front follower. v
