CAR-BOLSTER.
SPECIFICATION forming part of Letters Patent No. 565,405, dated August 4, 1896. Application filed April 4, 1896. Serial No. 586,190. (No model.)
To all whom t may concern:
Be it known that I, WILLIAM CASE, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car-Bolsters and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specication, in which- Figure 1 is atop plan view of the bolster, partly in horizontal section. Fig. 2 is a side elevation, partly in section. section on the line III III of Fig. 2.
The object of my invention is to provide a metal bolster for cars which shall be very strong, and capable of resisting the powerful strains to which it is subjected when in service.
The bolster is made of flanged metal beams set parallel to each other to constitute the side members, with metal ller-blocks connecting them at the middle and ends in order to bind them together rigidly.
I will now describe the construction of the parts of the bolster.
2 2 are steel channel-beams which form the side members and which are set on edge parallel to each other and sufliciently distant lat` erally to afford a bolster of the desired width. The flanges of the beams are preferably directed inwardly, though they may be directed outwardly. On the under side the beams are cut away at the ends at an inclination in order to secure the desired shape, and to connect the beams I employ at the ends filler-blocks 3, which are preferably made of cast metal and are hollow, having bottom plates or webs 4. Each block is of suitable width to fit between the webs of the channel-beams, to which it is secured by rivets 6, and between the sides of the blocks and projecting lips 7 thereon there are pockets or recesses 8, within which the ends of the webs fit, as shown in Fig. 1. These recesses cover the ends of the beams, and thus make a neat joint, and by passing the rivets through the lips and through the beams and the sides of the filler a triple thickness of metal is afforded at the ends of the bolster at the places of riveting. Snngfseats are formed on the under sides of Fig. 3 is a crossthe horizontal bottom plates 4. A third fillerblock, having a top plate 9 for supporting the center plate 9, is inserted at the middle of the bolster between the webs of the beams and fitting the upper and lower flanges thereof. This block is also preferably made of a hollow casting having flanges at its corners, through which it is riveted to the webs of the beams and having a central tubular opening 10 for the king-bolt. A bottom tension-plate 11 is also bolted to the lower iianges of the beams at the middle of the bolster, and the usual center plate 9 and the side bearingplates 13 are secured to the bolster, as shown. Vhen, as shown in the drawings, the flanges turn inwardly, the top plate 9' of the filler is recessed, so that the filler shall iit between the flanges of the beam and so that the surface of the filler shall be iiush with the top of the bolster.` A flat even support is thus given for holding up the center plate, and the load from the center plate is distributed by the ller to all parts of the bolster. The column-guides are constituted by the ends of the lips 7 and blocks or strips 12, which are fixed to the outer sides of the channel-beams parallel therewith.
By the construction above described I secure a bolster the castings of which are easy to make and the wrought metal of which is of merchantable form, which can be bought in the market. The bolster can therefore be made in large quantities rapidly. The parts are also easy to assemble, and the construction is cheap and possesses many advantages in respect to strength and resistance to strain. The parts may be bought separately and assembled .by the railway companies at their shops.
Within the scope of my invention many changes in the form and construction of the parts may be made by a skilled mechanic. Thus my broader claims are not limited to the employment of those structural beams which are commonly called channels, but will include the use of other flanged beams, and the filler-blocks may be modified in shape and construction.
1. A carbolster having side members conneeted at the ends by an interposed fillerbloek having lateral recesses with rivets passing through the lips of the recesses and through the side members and filler, giving triple thickness of metal at the place of riveting.
2. A hollow car-bolster having at the middlea filler-block, the top of which is iiush with the top member of the bolster and serves as a rest for the center plate.
A car-bolster comprising flanged beams set parallel to each other, a filler-block set between the same at the middle and having a central hole for the king-bolt, and-fillerbloeks interposed between the beams at the ends of the bolster.
el. A car-bolster comprising iianged beams set parallel to each other and constituting the side members of the bolster7 and a filler-block interposed between the beams at the end of the bolster and having recesses into which the Webs of the beams t, substantially as described.
5. A ear-bolster having parallel side members with separated bottom flanges, and a tension-plate connecting the same at the bottom and secured to said flanges.
G. A car-bolster comprising flanged beams.
