UNITED WILLIAM DI LowRY, or sT. Louis, MIssoUEI.
DRAFT-RIGQING.
No. 902,242.n
Specification of Letters Patent.
Patented Oct. 27, 1908.v
Application led September 19, lerial No. 893,608.
To all whom it may concern:
Beit known that I, WILLIAM D. LOWRY, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Draft-Riggings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of. this specification.
My invention relates to.v a draft rigging `and it has for its rime object the construction of a device ofP this charactercomprising a bolster or other fixed part of a car, a draft rigging operable in said bolster, and means w ereby the draft and buff'mg springs of the rigging are susceptible of combinedaction in unison with each otherA in both the draft and bufling movements of the draft rigging.
Figure l is a View partly in plan. and partly in horizontal section of'my draft rigging. Fig.v Il is a view partly inl elevation and partly in vertical section of my draft rigging.
1 designates a bolster which is provided with a central recess 2 extending transversely of thebolster and open at thebottom of the bolster. The bolster contains a central bolt hole 3 for the reception of a king-bolt, and located within the recess 2- is a stem 4 which is formed integral with the up er portion of the bolster, as illustrated in Eig. Il. The stem '4 contains a continuation of the kingbolt hole' 3. 5 is a bottom late that is de'- tachably secured to the bo ster and -which serves to normally close the bottom of( the recess 2 in the bolster.
6 designates the shank of the draw bar, andv 7 is a U-sliape yoke suitably secured to said draw bar shank and ada ted to operate in the recess in the b'olster 1 in such. position that it straddlcs the stem 4 of the bolster. TLie sides of this yoke bear at their inner faces ri s 8.
9 are inner follower blocks located within the yoke 7 and which face each other at oppgositc sides of the stem 4 in the bolster and are provided with side flanges 10 adapted to be engaged by the ribs 8 of the yoke 7.
11 are draft and bufling springs, the inner cndsof which are seated against the outerl faces of the inner follower blocks, one of said springs being located at the front of the bolster 1, and the other spring being located at the back or op osite side of the bolster.
12 are outer ollower blocks loosely mounted in the draw bar yoke and against which the outer ends of the draft and buing springsbear. The follower blocks 1.2l are preferably flanged in order that they will engage the sides of the draw baryoke to be su ported and guided by the sides of said arms of the members are further secured to the bolster through the lmedium of hooks 15 produced by bending the ends of' the arms and which are placedin engagement withI the top and bottom flanges of the bolster.
In -the practical use of my bolster and draft rigging, both of the draft and boiling s )rings l1 are placedfin yaction when the raw bar is moved in either direction, this action being due to a part of the bolster, that is the stem 4 thereof, serving as a resistance member for the inner follower block 9, which is rearinost relative to the direction of movement of the draw bar, and the resistance member 13 serving as a resista Ice member for the outer follower block 1'2 that is foremost relative to the direction'of movement of the draw bar, and further to the fact of the engagement afforded by the ribs 8 of the draw bar yoke with` one of the inner follower blocks 9. To illustrate this action more fully, it will be assumed that the draw bar is being moved yforwardly in draft action. In this instance, the outer follower block 12 within the rear end of the draw bar yoke is moved forwardly by said .yoke to carry it away from the resistance members at the corresponding side of the bolster, whereby the draft and builing spring in front of said follower block is compressed between said .block and .the opposing inner follower block 9. During the movement of the draw bar yoke, just mentioned, the ribs 8 of said yoke,
by engagement with the forward inner fol lower block 9, act to impart movement to said follower block with the result, of cornpressing the draft andbufling spring resting against it between said block and the opposing outer follower block 12, which isr'e-v strained from forward movement, due to en.- spring located at each sid'eor the bolster and gagement tlerewitli of the resistance memlinterposed between the bolster aiid resistance bers 13 at the forward side or the bolster. It i members7 and means whereby said draw bar Will be seen that a similar action takes'place is caused to act upon all of said springs iu'l 5 when the draw bar is moved in the opposite l eitlier a forward or rearward movement of direcllgion under bufhg strain. the draw bar, substantially as set forth.
c aim: The combination with a bolster and re. sistance members carried directly by the il C bolster and extending laterally therefrom at its sides, of a draw bar, a draft and boiling WM. D. LoWRY.
