JAMES S. ANDREWS, OF NEW YORK, N. Y.

UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed June 1,1907. Serial 376,854.

To all whom it may concern:

Be it known that 1, James S. ANDREws, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Underframes for Cars, of which the following is a specification.

This invention relates to underframes for railway cars and its object is, primarily, to provide a metal under-frame of strong and substantial construction and composed of standard sections consisting of steel castings and bars. I

Another object of the invention is to reduce the cost of manufacture, assembling and repairing by making the sections according to a comparatively few patterns and so as to be interchangeable, and assembling them in a manner which will permit the sections to be easily replaced. I

In the accompanying drawings illustrating one embodiment of the invention Figure 1 is a top plan view. Fig. 2 is a bottom plan view. Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is an enlarged detail view of the forward end of one draw-bar sill and showing parts of the end sill. Fig, 5 is a sectional view on the line 55 of Fig. 4. Fig. 6 is an end view. Fig. 7

is a sectional view on the line 77 of Fig. 1. Fig. 8 is a sectional view on the line 88 of Fig. 1. Fig. 9 is a detail sectional view on the line 9 9 of Fig. 1. Fig. 10

is a detail view showing the joint between two sections of a side sill.

Referring to the drawings the sidesills consist of two end sections 11 and a central section 12 (Fig. 1), these sections being made of cast steel in channel form (Figs. 7, 8). The upper flanges 13 of the sections of theside sills are depressed at their adjacent ends 14 to receive the upper tie plate 15 and rivets or bolts pass through this tie plate, the flanges 13 and the bottom tie plate 15 to secure the sections together. The lower flanges 13 are also secured together by rivets or bolts passing through said flanges and through

tie plates

16, 16 on opposite sides thereof (Fig. 3).

At each end of the frame is a draw-bar sill 17 which is provided with an opening 18 to receive the draw-bar and its attachments. The draw bar sill has side projections 19 which abut against side projections 19 on the projections 19. These projections are provided with suitable openings 21 for the brake rods and other parts (Fig. 8).

The draw-bar sill has a center bearing 22 on the bottom thereof (Figs. 2, 8). The draw-bar sills also have I-shape' projections 23 which constitute the end sections of the center sill and are connected at their inner ends to the ends of the middle I -shape section 24 of the center sill. The

sections

23 and 24 are secured together in the same manner as the

sections

11 and 12 of the side sills, by rivets or bolts passing through tie plates 25, 25 and the upper flange 26 of said sections, said upper flange being depressed at the ends 27 so that the upper tie plate 25 will lie flush with the top of the sections of the center sill. Tie plates 28 are arranged on the upper and lower sides of the lower flange 26 of the

sections

23 and 24 and are secured thereto by rivets or bolts (Fig. 3). Each draw-bar is provided at its forward end with an integral bufling surface 30, an opening 31 for the draw-bar (Fig. 6), and a pocket 32 for the draw-bar carry-iron 33 (Fig. 5). The end sill is made in two sections 34 and these sections are provided on their inner ends with cars 35 which lap over the side flanges 36011 the draw-bar sill and are riveted or bolted thereto (Figs. 4, 5, 9). The web 34 of each end sill section is riveted or bolted to a front flange 36 on the draw-bar sill (Fig. 5). The outer end of each end sill section has an car 37 at the top which is riveted or bolted to the upper flange 13 of the side sill section 11 and it also has a flange 38 which is riveted or bolted to the web of the side sill section (Fig. (3).

The transoms 39 are preferably made ofchannel iron and riveted or bolted at their ends to lugs 40 on the side sills and lugs 40 on the center sill (Fig. 7). Diagonal braces 41 are secured to lugs 42 on the side sills and to lugs 42 on the center sill, and straps 43 connect these braces to the transoms above them (Fig. '7).

The underirame consists of comparatively few parts, many of which are duplicates so that they can be made with the same patterns. This enables many of the parts to be used interchangeably; for example, the draw-bar sills are made alike and are interchangeable and the end section of each side sill is interchangeable with the end section at the opposite end of the other side sill. The sections of the underframe are made so that they can be easily secured together in, a strong and rigid manner and any section can be readily removed and repaired or replaced.

What I claim and desire to secure by Letters Patent is:

1. An under-frame for cars comprising a metal side sill provided with an integral projection constituting a part of the body bolster.

.flanges to overlap the ends oi the projections 2. An tindertrame for cars comprising a metal side sill. said side sill comprising a cast steel section provided with an integral projection constituting a part of the body bolster.

3. An underfraine for cars comprising a metal side sill composed of a plurality of sections, two of said sections being made of cast steel and each provided with a projection constituting a part of the body bolster.

i.
