HENRY A. WAHLERT, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO JOHN ADDIS,
OF MARSHALL, TEXAS. i
To all whom it may concern: y
Be it known that I, HENRY A. WAIILERT, citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Body- Bolsters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawingsforming a part hereof.
My invention has relation to improve# ments in body-holsters for railway cars;and
vit consists in the novel construction of bolster more fully set forth in the specification and pointedout in the claims.
In the drawings, Figure 1 is a top plan of my improved body-bolster, the car being shown 1n dotted outline; Fig. 2 is a bottom plan thereof; Fig. 3 isa side elevation of the bolster; Fig. 4 is a cross section on the line well known, are subjected to maximum .'ars' and impacts both when empty and W en loaded, the object thereofbeing to provide a body-bolster which shall have the draft members and the deadwood, u'suallyconstructed of timber, formed or cast integrally therewith, the whole forming a bolster composed of cast, or pressed steel, or malleable iron, and capable not only of withstanding the impacts to which the -car is subjected, but by reason of the truss-rod connection between the bolsters, resulting in a construc-v tion which distributes the impacts to the best advantage so that the life of the car is materially prolonged over that of cars in which the draft timbers and dead wood are -constructed of Wood. `The present 'con-l Specification of Letters Patent.
Application iiled September 6. 1907.
. vPatented. D60. 17, 1907.
Serial No. 391.642.
Referring to the drawings, Ain which arts that are old and well understood are-s iown in dotted outline merely, e, represents the end sill of the car, s, the side sills, and i, the
intermediate sills, and n., the needle-beams, these several features being old and forming nopart of the present invention. v Bolted to the bottom of the car, and adapted to rest on the car-truck T, is the body-bolster B, provided with side-bearings a, and center plate" c, the truck having suitable forma? tions to receive these parts, well understood in the art, and requiring no extended description. Disposed at'right" angles to the bolster B, and formed integrally therewith,
70 Vis the draft-member D, taking the place of L the usual wooden draft-timbers in prevailing freight car constructions. The member -D is extended rearwardly in the-form of an extension D to afford a more extended bearing tothe parts. The forward end of 4the member D terminates in a transverse im act or buffer member W, taking the place o the usual timber dead wood? member designed f to receive the impact of the nose or lug Z of the draw-head of the car coupler as presently to be seen. I
The up er wall of the draft-member,A has formed t erein .a pocket or depression p, bounded on each side by pairs of lateral oifsets or ways d provided with limiting walls or abutments h, h respectively,.th'ese abutments determining the extent of movement or reciproeation of the followers or plates displaced with any sudden impact against, or pull upon, the couplers or draft rigging of the ear as presently to be seen.
Secured to the ends of the member W are the ends of the pairs of truss-rods t, the same' passing longitudinally of the car over brackets or struts b 4on vthe bolster, thence under the needle-beams n, thel rods bein. provided with a turn-buckle t .as usua (Fig. 8). While the disposition of these truss-rods is not new, yet, in the present instance ,/coupled as they are at opposite ends to arts constitlie body-boltutin integral formations with ster they serve to distribute to better advantage whatever strains may pass through them, since these strains are communicated not only tothe specific portionB, but to the partsD and W, as well.
As in prevailing constructions, the present' bolster is equip ed with the automatic coupler 1 the rear o whose draw-,bar 2 is connect- '45 before -50 strap 3 for any pull between the cars.
formations (as shown, Figs. 2, 3) between` which the securing bolts are desi ned to pass,
it is obvious that these structura details may be varied indefinitely. The general longitudinal configuration of the part B is trussshaped, the bottom walls taperin toward the ends from the center-plate c. uch features of jconstruction as ma be illustrated,
'20 but to which 'no specific re erenceis herein made are well understood and require no description in this connection. l The upper wall of the-parts B and D, is disposed in the same plane, the terminal transverse buffer-member W having its rear wall disposed perpendicular thereto, and extending on each side of the part D, the extensions Ibemg reinforcedfby the lateral extensions or wings w of said upper wall. The roof of theY pocket pis depressed considerably below the upper edge of the member W, this arran ement bringing the center line of draft in line with the center line of the member D. Of course the end sill e must necessarily 'be notched to pass across the end of the pocket p but a portion of the sill willrest against the member D in the space between the pocket and rear wall of the member W. The ortion of the end sill resting in the space w wi l natu- 40 rally serve to take u a portionfof the impact to which the partfi is subjected, vthe construction tooserving t'o tie therparts well together. n
The side walls h, h ofthe lateral ways d as stated, serve to limit the movements of the followersfwith any abnormal push or pull against the spring 4, one followerbeing pushed by thec'oupler draw-bar for a push and the other follower being pulled byNthe orma the followers would each occu a p l.- sition about midway between the walsT h, h', vwiggle the'trainis in motion or at a standsti The present body bolster therefore com rises the bolster or transverse member B, tllie draft member D, D', and front crossbar or buffer member W, the latter projecting upward above the plane of the upper surface of the parts B an D, D. The ends 6b of the buffer member merge with the surface referred vto by the lateral extensions w already referred to. The bolsters at opposite ends of the car are `united by the trussrods t and the whole. forms a combination well tied together and difficult of displacement under the most adverse conditions.
Having described my invention what I vx claim iszl 1^ 1.l A body-bolster comprising a transverse C.70 truss-shaped bolster member, a longitudinal draft `member extending forward thereof, and partially rearward of said bolster, and substantially of channel' cross-section, and a front cross buffer member projecting above the plane of the common upper surface of the first mentioned members, the whole being formed 0r cast of a single piece of metal.
2; A body-bolster comprlsing a transverse vtruss-shaped bolster member, a longitudinal draft member extending forward thereof and partially rearward of said bolster, and substantially of channel cross-section, a'front cross buffer-member projecting above the lane ofthe common uppersurface of the st mentioned members, and lateral wings ,extended from said surface and meeting the base of the buffer member, the whole being formed of a single piece of metal, substantially as set forth. y 90 3. A body-bolster comprising a bolster member of truss-shaped design. disposed transversely of the car, a longitudinal chan- -nel or draft member having a rearward extension formed integrally with the bolster member, an outer cross buffer member rojecting above the plane of the upper s ace of the. bolster and draft member, lateral wings or formations forming extensions of said surface andconnected to the base of the i buffer member, a pocket formed in the upper wall of the draft member and having lateral voffsets or ways, the forward end f the j pocket terminating a suitable distance from the adjacent vertical wall of the buffer member, the latter member being formed integrally' with the draft member, as set forth, 1
