Patented Nov. 13, 1906.' y
To aZZ whom, t may concern:
Be it known that we, HARRY M. PFLAGER, CHARLES T. WEsTLAKE,and CLARENCE H. HOWARD, citizens of the ,Unitedl States, re-
siding at St. Louis, in the State ofMissouri,
have invented a new and useful Im rovement in Car-Bolsters, of which the fol owing.
ias for its object to produce a double body` bolster having its comonent-members arranged in the most a vantageous manner relatively -to each other for the greatest strength and rigidity of construction combined with compactness and economy of metal. v
Ordinarily a double b dy-bolster of this class consists of a rectan lar-shaped frame adapted to bear against t e under side of the car-sills and comprising, mainly, two side and end members, respectively united to each other at their ends, and a-middlexmember united at its end to the side members at right angles thereto and having the body centerbearing on its under side.`
Our invention consists principally in substituting for the ordinary side members and middle member two diagonally-arranged members intersecting each other at the middle or pivotal central ortionof the bolster, combined with other eatures of novelty, as hereinafter described and claimed, reference being had to the accom anying drawings,
forming part of this spec' cation, Whereon- Fi ure 1 is a top plan view of our improved doub e body-bolster; Fig. 2, aside elevation thereof; Fi 3, a vertical longitudinal section throug the bolster on line 3 3 in Fig. 1; Fig. 4, an end elevation thereof; and Figs. 5 and 6, vertical transverse sections therethrough on lines 5 5 and 6 6, respectively, in Fig. 1 looking to the right. j
Like letters and numerals of reference denote like parts in allthe figures. A a represents our .im roved double bodybolster, which is preferzibly composed of caststeel integral throughout and consists of tWo parallel and opposite end members b, spaced a suitable distance apart and adapted at the tog) to bear longitudinally a ainst the under si e of the outer sills 1 of t e car, to which they are fixed by bolts. (not shown) the usual well-known manner.
The endmembers b ma lbe of any suitable shape in cross-section an general configuration-such as L-shaped,"as shown-having When'assembled their'horizontal legs bearing against the sills v 1 and their upright legs arched, each member b being preferably formed at one end vwith two opposite longie tudinally-arranged depending lugs 2, be-
ltween which is coupled the end of the side body truss-rod-(not shoWnVand near its other end (or at suitable intervals longitudinally) with a stiHening-rib 3.
The end members b are' united to each other, preferably at or adjacent to their ends s by two diagonally-arranged members c, which are adapted to bear at the top against the under side of the longitudinal sills 1 of the car and intersect each other at the middle or pivotal central part of the bolster a, where the intersecting portion of the mem- `bers c is perforated vertically for the kingbolt (not shown) and otherwise adapted to form the body center-bearing 4. l
The diagonal members c in the present case are preferably-I-shaped in cross-section andinclined (or curved) from their'rnaximum depth at their middle and preferably .straight portions to their junction with the end members b, orA the members c may be `otherwise sha ed in cross-section and configuration, as ound desirable. I
The outer and inner top and bottom flan es of each I-shaped member c are united to t e adjacent corresponding flanges of the other member c at their angles of intersection by gusset-shaped extended portions 5 and 5', the ed es of the extended portions 5, which unite t e outer flanges sidewise of the bolster. a, being parallel to each other, respectively,-at an equal distance'from the longitudinal center line of the bolster a, whilethe extended ortions 5 of the inner iianges (endwise of the olster a) are preferably concave, the whole constituting a strong reinforcement'to the anges of the members c at their junction vwith each other and forming an extended bearing-surface therewith at the" top against the car-sills 1.
Transversely through the Webs 6 of the diagonal members c, immediately beneath the extended portions 5 and 5 of their top anges,
IOO
is formed on each side of the center-bearing 4 the usual opening (or openings) 7 for the passage therethrough of the middle platformsills (preferably metallic, as shown) d, which bear against the under side of the said top Vportions 5 and 5', the inner ends of thev platform-sills d projecting beyond the corresponding edge of the extended portion 5 at one side ofthe bolster a and bolted thereat to a coverplate 8, which when the parts are assembled butts longitudinally edgewise against the said edge of the bolster a. Similarly, the outer projecting portions of the platform-sills d and d are riveted to a cover-plate 8', which butts `laterally edgewise against the corresponding ed e of the extended portion 5, at the other si e of the bolster a, whereby end p'lay of the platform-sills d and d, which are secured iirmlyto the bolster a by bolts 9, is prevented.
e represents the side bearings, which span and are preferably integral with the diagonal members c at a suitable distance from the `center-bearing 4.
rectangular bolster.
Moreover, the diagonal members c being preferably united to the end members b at the ends .of the latter, any blow from collision on a corner of the bolster ais resisted by these diagonally-arranged members c and breakage of the bolster a therefrom prevented.
What We claim as our invention, and desire to secure by Letters Patent, is
l. A car-bolster, comprising two opposite parallel end members spaced a suitable distance apart and connected together by two diagonally-arranged members adapted therewith to bear at the top against the car-sills, the said diagonal members intersecting each other at the pivotal central portion of the members intersecting each other at their middle and adapted at the top to bear against the car-sills, the said-members being connected to each other at, or adjacent to their endsby a suitable member therewith 4and parallel to the said sills, substantially as described.
4. In a car-bolster of the class described,
the combination of two opposite parallel end members spaced a suitable distance apart, two members arranged diagonally and connected to the end members, and adapted therewith to bear at the top against the carsills, the said diagonal. members intersecting each other at the pivotal central portion of the bolster. and having respectively, openings transversely through .the body for the passage therethrough of the platform-sills, and iianges connecting the diagonal members gussetwise to each other at the top in their outer angles of intersection, the said anges having their edges straight and parallel to each other at each side of the longitudinal center line of the bolster, substantially as described and for the purpose set forth.
In testimony whereof we have signed our names 'to this specification in the presence of two subscribing witnesses.
