AJOHN IV. CLOUD, OF CHICAGO, ILLINOIS.
CAR-BOLSTER.
SPECIFICATION forming part of Letters Patent No. 588,555, dated August 24, 1897.
` Application filed April 20, 1897. Serial No. 632,905. (No model.)
To all whom t may concern:
Be it known that I, JOHN W. CLOUD, of Chicago, in the county of Cook and State of Illinois, have invented a vcertain new and useful Improvement in Car-Bolsters, of which improvement the following is a specification.
My invention .relates to bolsters through which the weight of a railroad-car body and its load is transmitted tothe axles and wheels of the trucksupon which the car is carried; and its object is to provide a rolled-plate structure which shall be properly adaptable to the conditions of such service and which shall present the advantages of lightness, strength, and comparatively low cost of construction.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawings, Figure 1 is a View, half in vertical longitudinal central section'and half in side elevation, of a bodybolster and a truck-bolster each embodying my invention and placed in operative relation; Figs. 2 and 3, plan or top views, each being half in horizontal section and half in elevation, of the body and the truck bolster, respectivelygligs. t and 5, transverse central sections through said bolsters, respectively; Figs. 6 and 7 plan and side views, respectively, each half in central section and half in elevation, of a body-bolster, illustrating a detail modification; and Figs. S and 9, transverse sections through the same at lthe lines m a: and y y, respectively, of Fig. 6.l
In the practice of my inventionI provide a,
truck-bolster, or oneY may be plane or hori zontal and the other inclined, as in the bodybolster, the bolster being in either case of maximum depth at its middle portion. The side members 3 y3 decrease in depth from their middle to their end portions in correspondence with the inclination that may be given to either or both of the upper and lower members, which they continuously space apart at the distance desired for the depth of the bolster, and held firmly together, the connection being effected by rivets 4, passing through the flanges of the side members and through the adjacent portions of the upper and lower members. The bolster is thus a box-beam structure ofmaximum depth atits middle and gradually reduced therefrom to its ends.
In the body-bolster shown in Figsrl, 2, and 4 the webs of the side members are solid or unperforated, while in that of Figs. 6 to 9, inclusive, openings 5 for the passage of drafttimbers are formed in the side members on ,opposite sides of their middle vertical plane.
In order to compensate for the weakening of the side members by the` cutting vaway of metal to form said openings, the upper and lower members 1 and 2 are in such case preferably formed with widened or laterally-extended central portions 6, by which means correspondingly-increased strength is imparted to the bolster as a whole.
The body-bolster isconnected to the sills of the car by bolts 7, passing through the upper and lower members and through the flanges of the side members and provided with nuts on their lower ends. Truss-rodseats and side bearings may be connectedto the bolster and be properly supported in any desired positions. The truck-bolsteris provided wit-h column-guides 8, which are riveted to the side members 3 3 in proper positions to tit between the columns of the truck-frame. Center plates of anysuitable and preferred construction are connected to the middle portions of the holsters.
I claim as my invention and desire to secure by Letters Patent--- I l. A rolled-plate car-bolster composed of upper and lower plate members, and two interposed side members, forming a structure of box or tubular section from end to end,the
side members being inclined from their mid-l dle portions toward their ends and provided with flanges connected by rivetsto the upper and lower members, substantially as set forth.
2. A rolled-plate car-bolster composed of upper and lower plate members, and two in- IOO tions, and two interposed side members which are inclined from their middle portions toward their ends, and provided with flanges Connected by rivets to the upper and lower members, and openings in their webs on each side of their middle vertical plane for the passage of draft-timbers, substantially as set forth.
