T0 all wlw-m 'it may concern:
Be it known that I, GEORGE A.. Jenn son, a citizen of the United States, residmg at Chicago, in the ccuntyof Cook and State of- Illinois, have invented a certain new 'and useful Improvement in ,Draft-Rigging for RailwayCars, of which the following rs a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specication.
My'invention relates to improvements in draft rigging for railway cars. The object of my invention is to-provide a draft rigging of simple -construction and efficient operation.
In the drawings forming u specification Figure l is a side elevation longitudinal vertical section -on line 1-1 of'Fig42 lof a draftrigging einbodying my invention. Fig. 2 is a plan-view partly in horizontal section on line 22 of Fig. 1. Fig. 3 is a plan view partly in horiv zontal section illustrating the position of the parts of the draft rigging when under'full movement. Fig; 4
compression in pulling longitudinal section the illustrating the position of the parts of draft rigging when under full compression.
in buffing movement.
Referring to the drawings 6, 6 represent draft sills or parts ofthe car frame to which the draftlrigging is applied, 7 the end sill, 8 the buder block, 9 the draw bar carry iron1 10 the tie plate adapted' to support the draft gear and suitablysecuredto the draft members, preferably' by lthe bolts draw bar connected'to 'the draft yoke 13, 14, 14 the rear stop members provided .with the stop shouldersl, 15, y16, 16 the front stop members each provided with a slotl or recess 17, the said slots being in opposed relation to each other between -he ' draft members 6, 6, and adapted to receive the ends of the front follower 18 hereinafter described.
The draft gear 19 is mounted within the draft yoke and comprises a shell 20, preferapart of this.
faces 33, there being construction.
shell are the friction members andspring members 24. Thel spring members preferably comprise an outer spring Q5 and an inner spring Q6I nested therein, vthe said springs being rearwardly seated against the shell and forwardly .seated against the friction members. The friction members 23' coiiiprise tlie .friction shoes- 27, 'the' 'wedge '28, and in preferable construction the antifriction rollers 29 interposedl between tliewedge and the friction shoes. The friction shoes cTfare preferably three in number, and
illustrated in Fig. 3 of the drawings. It will i.,
be obvious that theactionof the gear is aspring action only on forward movement of the draw bar and thatthe release action in the return of the arts to normal position after compression A1n pulling movement will be an easy return without rebounding of the spring.- n l On rearward movement of the draw bar the shell is stationary against the rear stop members,` and thegwedge is forced rear.
'wardly without the vinterposition of the front-'1 follower in the action spreading the friction shoes andV forcing the same rearwardly,"compressing the springs within. the
shell untilon complete rearward movement of the parts the friction shoes aregcoinpressed within the shell and the rear end of the draw .bar engages the front face -of the front follower 18, as illustratedy'in Fig.- 4 of the drawings.
I claim 1. kIn .a 'draft rigging formailway cars, in combination, a'l draw bar, stop members, a front lfollower, a shell, friction shoes and wedge? within the shell, the frontfollower havinglv .an opening therethrough for the` passage of the wedge, thel said wedge being adapted to directly. engage the draw bar on rearward' movement thereof.
2,.5lr1l aj'draft 'riggin for railway cars, in Combination, a draw ar, stop members, a draft'yokaa shell,` springs, friction shoes and-wedge within'I the shell, and a front follower, thei'' front follower being stationary in vboth/pulling and buifing movementv of the4 draft rigging, and having an opening therethroughfor the vpassage of kthe wedge.
3. In av-draft rigging for railway cars, in
' combination, a draw bar, stopl members, a
draft yoke, a shell, springs, friction shoes and wedge within the shell, the front follower being stationary and having an opening therethroughffor the passageof the.
wedge, the friction shoes engaging the front follower and being stationary in relation thereto on forward movement of the shell. 4. In a draft rigging for railway cars, in combination, sa' draw bar, stop members, followers, a shell, springs, friction shoes and wedge within the shell,` the wedgebeing actuated independently. of the front fol-` lower, and. the frition shoe'sgand theffront follower lbeing in lenga-gement with each vother and stationary-in relation to the stop members on forward movement of the' draw bar.
5. In a draft'rigging for railway cars, in combination, stop members, a draw bar, a
draft yoke, a shell, springsjfriction shoes and wedge'withinthe shell and a stationary front follower, the wedge 'passing through the front follower, the frictionishoes-being stationary in relation to the front follower lon forward movement of the shell, and in such movement acting as a seat against draw bar.
8.' In a draft Vrigging for railway cars,
.in combinationfa draw bar, a draft yoke, a shell, sprmgs, friction 'shoes and wedge within the shell, front and rear lstop members and followers, the front stop members being provided with .recesses to receive the front follower in- -its stationary position therein, the front follower being provided with an opening for the passage ofthe wedge therethrough, the said wedge being adapted to act independently of said follower, and to spread the friction shoes only on rearward movement of the draw bar.
9. In .a draft rigging for'railway cars, the combination of a draw` bar, a shell, a stationary front follower andy means for connecting the shell to the draw bar, of compression resisting members rwithin the shell comprisingsprings, friction shoes and 4a wedge, the said wedge being 1n direct lill@ engagement with said draw, bar,"`said front s follower-being located between the friction Shoes and the rear end of the draw bar.
10.In a draft rigging for railway cars,
the combination with a draw bar, friction shell, and means for connecting the shell to the drawr bar, of a stationary follower, friction shoes and springs mounted within said shell, said shoes and springs being located on one side` of the stationary follower, a wedge coperablev with said shoes, and means for operating the .wedge upon movement of the draw bar in one direction only,
*thel wedge being 'vinactive'in 'movement'of lao the draw bar in the opposite direction and vment of thel shell', said's'eet being adapted said shoes being held stationary by said for the passage of thewedge, said-wedge 10 statio'nlaify fllofwer duringf such Ilnovemen't. being operative independently of said seat. 1l. n a ra t rigging onrai way cars,
