Specification of Letters Patent.

Patented Oct. 2, 1906.

To @ZZ whom it may concern:

Be it known that I, SPENCER OTrs, a'citizen of the United States,- residing at Chicago, in the county of Cook and State of Illinois, have invented certain `newand useful Imrovements in Railway-Cars, of which the following is a specification.

My invention relates to railway-cars, and has for its object to improve the construction thereof by providing a new improved bolster and sill construction, as is more particularly pointed out in the specification and accom anying claims. In t e drawings, Figure 1 is a longitudinal section on the line 1 of Fig. 2, showing parts of the bolster and longitudinal sill. Fig. 2 is an end elevation, partly in section, the sections being made on the lines 2 and 2a of Fig-.HL

' the drawin s, a represents the side members of a bocgly-bolster, these members bein formed from an integral metallic plate Whic extends continuously from end to end and from top to bottom of the bolster.

b represents the top member of the bolster, composed of a metallic plate, which is connected to the side members a,l by means of angle-bars c, having one iiange riveted to the top plate and the other to theside members of the bolster. f.

d represents the lower or tension member of the bolster, which is made of a channeled metal bar having its flanges secured to the sides of the bolster.

e represents the top plate of the longitudinal sill. The side members f and f of this sill are formed of channel-beams, as shown, and they are securely riveted to the sides of the bolster, the members f being secured to one side and the members f' to the opposite side thereof. Angle brace-plates n, riveted to the bolster and to the side members lof the sill, comprise the means for securing said side members to the bolster. above mentioned, e represents the top plate of the longitudinal sill. This top ate is continuous and passes through suita le slots formed in passes t ough it by means of angle-bars g,

riveted to the side members of the bolster and to the top plate. Brace-plates IL are secured to the top plate adjacent the side members ofthe bolster.

c represents the center bearing, suitably secured to the bottom of the bolster and of the longitudinal sill.

7c represents angle brace-plates bracing and strengthening the bolster at its lower central portion.

l represents side bearings formed of a U- shaped metallic stra securely riveted to the side members of the olster, and l represents metallicy brace-plates also riveted to the side members and to the metallic straps, as shown.

m represents suitable metallic tracks attached at their ends to the side members of the bolster. These tracks are to be used when the bolster is used in a dumping-car having dumping-doors in its bottom and are used to guide the door-operating means in a well-known manner.

My improved bolster and sill is of extreme simplicity and may be made from metallic parts, Which maybe rolled or bent into shape without the em loyrnent of special patterns therefor. Byt e arrangement Which I have described I am enabled to produce a structure which is exceedingly strong and efficient forits purpose.

I claim- 1. A bolster for railway-cars having a top late, a channel-bottom therefor, side members com osed of integral metallic plates extending etwe'en the top and bottom members and from end to end of the bolster, and angle-bars riveted to the top plate and to the integral side plates.

2. In a railway-car, the combination of a bolster having. inte al metallic side plates extending between t e top and bottom members of the bolster and from end to end there- -of said side plates being provided with slots,

longitudinal sills comprising separate sill members secured to the opposite side plates of the bolster, and a continuous top member secured to the side members and passing throu h the yslots in the bolster.

3. El a railway-car, the combination of a bolster having inte al metallic side plates extending between t e top and bottom members of the bolster and from end to end thereroo ros

of, said'side plates being provided with slots, longitudinal sills comprising side members secured to the `opposite side plates of the bolster, a .continuous :top member secured to the side members and passing through the slots in the bolster, and means for bracing the bolster adjacent the slots.

4. A bolster for railway-cars having integral metallicy side members extending between the top and ottom members and from end to end of th bolster, and side bearings composed of U-shaped metallic straps secured tothe side members.y

'5. A bolster for railway-cars having integral metallic side membe'rs extending between the top andbottom members and from end to end of the bolster, side bearings composed of U-shaped metallic stra s secured to the side members, and braceates for the atraps secured thereto and to t e side memers.

6. In a railway-car, a bolster havin inte- .gral metallic side plates connected to t e top and bottom plates and extending from end to end of the bolster, and metallic tracks for door-operating means connected to the side mem-bers at the ends of the bolster.
