ERIC W. PALMQUIS'I, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE SHICKLE, HARRISON 85 HOWARD IRON COMPANY, OF SAME PLACE.
BODY-BOL ST ER FOR RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 660,920, dated October 30, 1906. Application filed June 4, 1960. Serial No. 18,928. (No modelz) T aZZ whom it may concern.-
Be it known that 1, ERIC W. PALMoUIs'r, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Body Bolsters for Railway-Cars, of V 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 improved body-bolsters for railway-cars which are made of cast steel of box shape and the center bearing of which is strengthened or supported by an in- I 5 tegral brace or braces.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a top or plan view of my improved bolster. Fig. II isabottom view. Fig.
III is a view part in elevation and part in vertical section. Fig. IV is a detail vertical section showing a modification of the braces for the center bearing. Fig. Visa horizontal section taken on line V V, Fig. IV.
The bolster is made of cast-steel and is in box form, having vertical sides 1, a fiat top 2, and a bottom 3, inclined upwardly in both directions from the center. The bolster is hollow, and its top, bottom, and sides are preferably formed with openings 4 to lighten it. The flat top of the bolster receives the sills 5 of the car-body, and to provide'for the attachment of the sills to the bolster the latter is 5 formed with holes 6 in its top and bottom to receive connecting-bolts that extend through the sills.
The bottom of the bolster is provided with integral side bearings 7 and an integralceno ter bearing 8, adapted to bear, respectively, against the side bearings and center bearing of a truck-bolster.
(Not shown.) For the purpose of strengthening the center bearing, upon which great strain is often exerted, I form integral with the bolster a brace which 5 may be in the form of a sleeve 9 through which the king-bolt passes, as shown in Fig. III, or it may be in the form of wings 10, extending from a central hub on the center bearing to the bottom and sides of the bolster, as shown in Figs. IV and V. By thus bracing the center bearing it resists all pressure or strain that may be brought upon it.
box form consisting of sides, a bottom, and a top; said bottom having integral side and center bearings and the center bearing being strengthened by an integral brace, substan- 7o tially as set forth.
2. A cast body-bolster for railway-cars of box form and consisting of vertical sides, a flat top, and a bottom inclined upwardly in both directions from the center, said bottom being provided with ledges 12 and center and side bearings and the center bearing being strengthened by braces cast integral'with the bearing and the body of the bolster, substantially as described.
