Specification of Letters Patent.

1' gall whom it may concern: 1 gee it .known that 1, JOHN OQonnon, eicitizen of the llnited States, residing at Ghicago, in'the 'county of Cook and State in the drawings forming a ,part of this.

specilication, Figure 1 is a plan view of a draft rigging embodying my invention;

Fig. 2 is a vertical longitudinal section on line 2-2 of Fig. 1; Fig. 3 is a cross section on line of Fig.2.

Referring to the drawings, the numerals indicate draft sills or parts of the car frame to which the draft rigging is'applied 5-5 represent cheek plates, draft lugs or side castings, the same being oppositely ar ranged between the draft sills, and each being secured to the adjacentsill by any suitable means, preferably the rivets 6 6.

The numeral 7 indicates a. draw-bar, only the rear portion thereof being shown in -the drawings, having a transverse slot 8 to re oeive the coupler-key S), which passes through slots 10 in the adjacent liuibs'of'the draft yoke 11" and through slots l2l2 in the draft, sills. Each cheek plate, draft lug or side casting 5 is provided with a preferably integral housing 13 to receive an end of the shoe 1%. The shoe 14: is mounted between the cheek plates, draft lugs or side castings 55 and is preferably of a general cylind rical shape, the lower; face 15 thereof being squared and having a. recess or groove 16 therein. The housing 13 at either end of the shoe l4 conforms in shape to the adjacent faces of the shoe, the lower opening 17 of each housing being of a lesser Width than the (llulTMItGlUO'f the shoe 1 to prevent the downward displacement of the shoe. A bolt 11%, or other suitable means, is passed through the shoe l land through suitable perforations 19 in the upper ends of the upper set 20 of platesor springs, the said plates alterniitin'g in their arrangement with the plates or springs 21 of the lower set-of springs.

Patented May 4, 1915. 1

Thelow'r springs 21 are received in a groove or recess 22 in the upper face of a shoe 23, which is similar in construction to the shoe 14, the lower set'of'plates 21 being held in said recess by a bolt 24 passing through the said shoe, preferably at its middle portion. The ends of the'lower shoe 23 are received in, and home by a housing at either end, each of said housings 25 consisting preferably of a separable member received Within a slot 26 in the lower central portion of a check plate, drafting or side casting Each of said housings 25 receives an end of the shoe 23 withinits appropriate recess 27, the walls of said recess conforming to the adjacent bearing faceof the shoe 23.

The upper and lower spring" plates pass through a vertical opening 30 in a block 31 which is received Within the yoke 11, its sides engaging the limbs 3131 of the yoke in preferable arrangement, and its forward and rear ends preferably engaging the draW- bar 7 and the rear member of the yoke 11, respectively. The front and rear walls forming the opening 30 in the said block are convex, as illustrated in Fig, 2-of the drawings.

In mounting the compression resisting parts of the draft rigging between the draft sills, the upperset of springs is inserted in the shoe l4, and secured therein by the bolt 18, the said springs being passed through thebpening' in the block mounted within the yoke, and thereupon the lower housings 25, with the lower set of springs and lower shoe assembled therein, ore-passed 'into position from underneath, the lower housings then being ui'ipropriately secured to the sills anl side castings preferably by the bolts ltd--35. The upper faces 3636 of the lower housing, IliOtIilJQiS support the block within the yoke and also support the yoke, the limbs of the yoke and the block being in sliding engagement therewith in 100 the operation of the gear.

()n forward movement of the draw-bar,

the blook withintlie yoke is drawn fol? wardly, its movement being resisted by the from the secured ends of the other set. 'The forward movement of the block is limited 9 Springs passing through the block, the

by the confor fiii tion of the sprin gs to convex rear face forming theopening 30 through the block. During the forward movement of the draw-bar, the upper and lower shoes rotate in their respective housings.

On rearward movement of the draw-bar,

the, block Within the yoke is moved rearwardly, the upper andlower shoes rotating in their respective housingsas the sprlngs are rearwardly flexed. The frictional action between the upper and lower sets of springs occurs in a manner similar to that described upon forward movement of the draw-bar,-

the rearward movement of the block being limited by the'conformation of the springs to the convex face forming the forward wall of the opening in the block.

1 claim:

1. In a draft rigging for railway cars, in

combination, draft members, a draw-bar,

cheek plates, draft yoke connected to the draw-bar, a slotted block within the draft yoke, two sets or spring plates, upper and lower rotatable shoes,

I and separate housings- "ior the lower shoe, the cheek plates being provided with housings to receive the upper shoe, nected at one end to the upper shoe, the

' other set of spring plates being connected at one end to the lower shoe.

2. In a draft rigging for railway cars, the combination with draftmembers having cheek plates secured thereto, of an upper shoe extending from one cheek plate to the other and mounted in bearings carried by said cheek plates, a lower shoe extending one set of spring plates being con from one-cheek plate to the other cheek plate and rotatably mounted in bearings carried thereby, and spring plates secured at their ends in said shoes.
