RADIAL DRAFT-GEAR.

Specification of Letters Patent.

Patented Sept. 29,- 1908.

Application 11106. May 13, 1905, Serial No. 260,264. Renewed September r7, i907. Serial No. 393,324.

To all whom it may cor/teem: Be it known that I, HAianrT. .KRAKAU, of Cleveland, Cuyahoga county, Ohio, have invented a-new and useful Radial Draft-Gear,

of which the following is a full, clear, and exact description, reference being had to the accompany' g drawings, forming part of this specification, in whichlon itudinal section showing dated December-'1, 1903.

. ster somewhat larger rear end of the bearin Figure 1 is a plan view of a draft-gear embodying my. invention; Fig. 2 is a vertical elevation of the bolster thecenter casting to which the frame of the draft-gearis pivoted; Fig. 4 is a side elevation ofthepiece which supports the okeand serves as part of theconnection of t e gear-rigging wit an end view'partly in section of the piece shown in Fig. 4; and Fi 6 is a vertical cross-section .on the 'line -VI of Fig. 2'.-

1; ig." 3 is a side 1My invention is an'improvement on the radial draft-gear for which Ihave already obtained Letters Patent Reissue No. 12,178,

As shown in the drawings, 2, 2 representthe center-sills ofthe car, 3 the end si 4' the bledy-bolster, and 5 the truck-bolster. At t e interpose-between thes'ills' a casting 6,

the. construction of which. is shown in -F1gs.

1 2v and It fills'the space between the SlllS being riveted or bolted thereto at its sides,'and;has at its forward end an open socket constituted by; upper and lower flang 6 in which the rear. end of the geari" frame is. set, "vertical holes being formed in the flanges to receive the pin 7 on which the gear-rigging frame swings radially. Obviously the parts can be reversed, the socket being formed on thelendfof. the gearrigging and fitting a projection on thecast- 6 I mg v A The .draft-gear'frame 8 is preferably a castwhich fits in the socket'6, being held therein by the pin 7. It also preferablyhas shoulders 6*" which may abut against the ends ofthe flanges16. The socket'is at theextreme forward end of the piecefi. i A A The pinehole in the bearing-9 is made than the pin, so that the can abut against the base of the socket an .transmit' -thereto the strains .of bufling; The forward end ofjjthe supports t on: the line-II II of Fig. A

' may be the truck; Fig. 5 is [ilace where the center sills cross the bol-' frameis supported under the end-sill by'a carry-iron 10, and in the frame is set the draft rigging 'roper, comprising a drawbar-shank 11', a yo e 12 and spring mechanism and fol-' lowers (shown by, dotted lines).

.The draft-gear frame constitutes in efiect a swingin draft-beam which contains .and e longitudinally movable part of the draft rigging. .It therefore has end shoulders I) constituting stops'for the followers, and itmay have intermediate stops if desired. At the forward end of the frame it provided with filling pieces 0 at each side of t e shank of the draw ar j To support the yoke and followers and also to afford means for connecting the draft-gear frame to the truck, I employ a yoke-support shown in detail in Figs. 4 and -5. .It consists preferably; of a casting 13 having vertical flanges 14 adapted to receive and to be bolted to the side-plates of the franieby bolts 15, and having a middle portion 16' adapted to receive the yoke. It also has lipsv 16 bearing'against the inner surfaces of the side plates; and at its base it has preferably a longitudinal strengthening flange 17, and dependin lateral flanges or lugs 18 formed with bolt 'oles 19 to connect it with the guiding spring-rods 20 which are pTonnected pivotally thereto as shown in ig. 1. ably comprises a'r'o'd20 which is pivoted to Each of these guiding-rodspreferthe yoke-support as above stated and extends telescopically within a rear'piece 21 which extends forward preferably in the manner'of a cage over the spring 22 and has a collar 23 in advanceof the spring. The

rear piece 21 is connected by a pivot-pin 24 V with a link 25 hich is connected by a pin 26 with the truck-bolster, the pins 24 and '26 being set at) right angles to each other so as to afford a joint fiexi le in two directions and thus adapted to provide for vertical as well as horizontal relative motionbetween "the parts.. The draft gear frame is therefore capable of rising and falling relatively to the-truck and the truck is allowed to rise and fall in relation to the car-bod without puttingany strain tion. The doubly upon the true connecilexiblejoint may be at the forward end of the guiding connection insteadof the rear end, or such joint may be placed at both ends thereof.-

advantages of my invention in'respect. of the simplicity and strength of the device will be appreciated by those skilled in the art.

Within the scope of my invention as broadly claimed the parts may be modified since hat I claim is 1.. A radially movable draft-gear having a frame adapted to carry longitudinal parts of the draft rigging, said frame pivoted, with a socket connection at its rear end to the car-frame, and having an end bearing at the socket, and a pivot pin holding the frame at the socket and fitted in a hole of somewhat larger diameter than the pin; substantially as described.
