HARRY T. ANDERSON, OF AVALON, PENNSYLVANIA, ASSIGNOR TO STAND- ARD STEEL CAR COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPO- RATION OF PENNSYLVANIA.
TRUCK-BOLSTER.
SPECIFICATION forming part of Letters Patent No. 743,415, dated November 10, 1903.
Application filed June 10, 1903.
To a/ZZ whom t may concern:
Be it known that I, HARRY T. ANDERSON, a resident of Avalon, in the county of Allegheny and State of Pennsylvania,have invented a new and useful Improvement in Truck-Bolsters; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to bolsters for railwaycars and the like, and more especially to bolsters of the trussed type.
The object of my invention is to provide a bolster which can be adapted either as a truck-bolster or as a body-bolster and wherein the maximum strength is secured with a minimum weight of metal.. To this end the bolster is composed of two Vtrough-shaped members placed with their webs horizontal and back to back and suitably secured together at their ends and separated by astrut at their middle portions, one or both of said members preferably being provided with outwardly-projecting flanges, to which a cover strip or plate of any desired length and thickness can be conveniently secured to strengthen said member or members and adapt the bolster to varying conditions of use and load.
In the accompanying drawings, Figure 1 is a side view of a truck-bolster constructed according to my invention. Fig. 2 is a plan view of the same. Fig. 3 is an end view of the same. Fig. 4 is a vertical central transverse section through the same, and Fig. 5 is a side view of a body-bolster constructed according to my invention.
The truck-bolster is composed of tension and compression members,a central strut,and
When adapted as a body-bolster, the strut may be omitted and such other changes made as will readily suggest themselves to those skilled in the art.
The tension, and compression members are preferably alike and are so shown; but this is not absolutely necessary.
In Figs. 1 to 4 of the drawings the compression member of the truck-bolster is formed of a trough-shaped member l, provided with outwardly-projecting flanges '2, to .which is Serial No. 160.885. (No model.)
riveted a cover strip or plate 3. The tension 5, having riveted thereto the cover-plate 6.
'lhe trough shaped members l and 4 are placed with their webs horizontal and preferably back to back and preferably having their ends secured directly to each other by rivets, as shown. They are spread apart at their middle portions to form the truss and have securedtherebetween the strut 8, which may be of any desired shape or construction and which preferably will be of cast metal having lips 9 embracing the top and bottom members and secured in place by riveting directly to the webs of the troughs. ably the upper member will be straight and the lower member alone bowed, as shown; but this is not essential, as both of said members may be bowed or the upper member bowed upwardly, lwhile the lower member is straight. When used as a truck-bolster, column-guides 10 are riveted to the vertical portions of the troughs 1 and 4at their ends and project slightly beyond the iianges 2.and 5. The center plate 11 and side bearings 12 are riveted to the top member, and preferably a filling-piece 13 is placed in the trough 1 at its center to strengthen the trough below the center plate. When adapted as a body-bolster, the column-guides will be omitted and the center plate and side bearings riveted to the lower instead of to the upper member. The strut may also be omitted in body-bolster and the top and bottom members secured directly to each other for their full lengths, as shown in Fig. 5.
The bolster shown and described can be made of any dimensions and proportions, as the troughs 1 and 4 are formed by pressing a plate inte shape, and the cover-plates 3 and 6 obviously can be made of any width orthickness. The design can therefore easily `behvaried to adapt the bolster to special "conditions of use and load. The vertical portions of the troughs give a relatively large vertical loadcarrying strength, and the outwardly-extending iianges 2 and 5 add materially to the strength of the bolster to resist lateral forces.
Prefer- The tension and compression members are practically box-girders, this giving the maximum strength to resist forces applied in all directions. To meet peculiar conditions of load it will only be necessary to increase the thickness or width of either the plate 3 or the plate 6, while for very'light work one of said plates may be entirely omitted and the other replaced by short sections to serve as bases for the center plate and side bearings or for the car-sills.
What Iclaim as my invention, and desire to secure by Letters Patent, is-
l. A car-bolster composed of two troughshaped members placed with their webs horizontal and back to back, and suitable connecting means between said members.
2. A car-bolster composed of two troughshaped members provided with outwardlyprojecting flanges at their edges, said members -being placed with their webs horizontal, and suitable connecting means between said members.
3. A car-bolster composed of'two troughshaped members provided with outwardlyprojecting flanges at their edges, said members being placed with their webs horizontal and back to back, and suitable connecting means between said members.
4. A trussed car-bolster composed of two trough-shaped members placed back to back with their webs horizontal, said members being secured to each other at their ends and being separated at their middle portions, a strut secured between said members attheir middle portions, and a center bearing-plate secured to one of said members.
5. A trussed car-bolster composed of two trough-shaped members provided with outwardly-projecting flanges at their edges, said members being placed with their webs horizontal and being connected to each other at their ends, and a strut secured between said members at their middle portions.
, 6. A car-bolster composed of two troughshaped members placed with their webs horizontal and back to back, suitable connecting means between said members, and a coverstrip secured to the compression member.
7. A car-bolster composed of two troughshaped members at least one of which is provided with outwardly-projecting flanges at its edges, said members being placed with their webs horizontal and back to back, suitable connecting means between said members, and
a cover-strip secured to the outwardly-pro-- jecting flanges of the one member.
8. A car-bolster composed of two troughshaped members provided with outwardlyprojecting flanges at their edges and placed with their webs horizontal, cover-plates secured to said flanges, and suitable connecting means for said members.
9. A car-bolster composed of two troughshaped members provided with outwardlyprojecting flanges at their edges, said members being placed with their webs horizontal and back to back, suitable connecting means between said members, and cover-plates applied to the flanges of said members.
10. A trussed'car-bolster composed of two trough-shaped members placed with their webs horizontal and back to back, means for securing said members to each other at their y ends, a strut secured between said members at the middle portion, the compression member being provided with outwardly-projecting flanges at its edges, and a cover-plate secured to said flanges.
1l. A trussed car-bolster composed of two trough-shaped members provided with outwardly-projecting flanges at their edges, said members being placed back to back with their webs horizontal, means for securingsaid members to each other at their ends, a strut secured between said members at their middle portions, and coverplates secured to the ilanges of said members.
l2. A trussed car-bolster havinga compression member formed as a boX-girder, a tension member, a strut, suitable connecting means, and a center bearing-plate secured to the compression member.
13. A trussed car-bolster having a tension member formed as a boX-girder, a compression member, a strut, suitable connecting means, and a center bearing-plate secured to the compression member.
14.. A car-bolster composed of tension and compression members formed as boX-girders, and suitable connecting means.
In testimony whereof I, the said HARRY T. ANDERSON, have hereunto set my hand.
