CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 621,275, dated March 14, 1899.

Application filed August 2, 1898. Serial No. 687,556. (No model.)

To all whom it may concern..-

Be it known that I, RICHARD W. OSWALD, a citizen of the United States, residing at Bloomsbu'rg, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvementsin Car-Trucks; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in car-trucks; and it consists in constructing'a the said angle-irons being bent at their ends, so that the upper angle-iron forms the outside member of each pedestal and the lower angle-iron forms the inside member of each pedestal and means for binding the parts together.

It also consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of a car-truck constructed in accordance with my invention. Fig. 2 represents a top plan viewof aportion of the same, parts being shown in section to better reveal the construction. Fig. 3 represents a detail end elevation of a portion of one side of the said car-truck. Fig. l represents a detail side elevation of the bent end of the upper angle-iron forming a part of one side of the truck. Fig. 5 is a detail showing another manner of reinforcing the pedestal, and Fig. 6 represents still another manner of doing the same.

1 in the drawings represents my improved truck, 2 upper, and 3 lower, members of the sides of the truck.

In constructing trucks for heavy travel, especially for heavy freight and the like, it it desirable to make the same very strong and yet as cheap as possible. In carrying out this idea I contemplate constructing trucks having bolsters formed of channel or I-beams and the sides of angle-beams. As shown in the drawings, the bolster 4 of the truck is preferably constructed of channel-beams, as 5 5, upon which the center-bearing maybe mounted in the usual way. The flanges of the channel-beams 5 are preferably cut away at the ends, so as to leave the web, as at 6, projecting beyond the ends of the flanges, which end portion can be bent at right angles and bolted to the sides of the truck, as seen at Fig. 2 of the drawings. I-beams can be used in place of channel-beams, the Web at the ends being extended in the same manner as shown and described with respect to the channel-beams.

The sides of the truck are preferably con structed of angle irons or beams 2 3, the vertically-arranged portions of the said beams being preferably wider and of greaterstrength than the horizontal portions thereof. As illustrated in the drawings, the upper angle beam 2 is arranged with the horizontal flange upon the top, while the lower beam 3 is arranged with a horizontal flange at the bottom. In placing the beams together to form a side the lower edge of the vertical member of the beam 2 rests upon the upper edge of the Vertical member of the beam 3 at the central portion of the said beams. As the beams approach the pedestals they are separated slightly, as at 7, the upper beam being bent upwardly and then downwardly to form the top and outer side of each pedestal 8. As seen in Fig. at of the drawings, the vertical member or leg of the angle-beam 2 is cut away and tapered, so as to make a pedestal of the required shape. The portion forming the outer leg of the pedestal can be thus safely tapered, because the strength required at this point is less than upon the horizontal portion of the beam. The ends of the lower angle-beam 3 are bent downwardly and out to form the inner member of the pedestal 8. Each pedestal is completed by bolting reinforcing angle-irons, as 9 9, upon the inner and outer surfaces of the vertical legs of the beams 2 and 3. The angle-irons 9 9 are bent in the form of an inverted U and form between their vertical portions spaees to receive the journal-boxes 10 of the truck. Any suitable spring 11 and cap 12 may be interposed between the top of each journal-box and the top of each pedestal to support the truck properly upon the said journal-boxes. A bottom brace-rod, as 13, connects the pedestals of the truck, being bolted between the lower ends of the angle-irons 9 9 upon each member of each pedestal.

In order to strengthen the connection between the bolster and the sides of the truck, I insert a brace-plate, as 14:, which is bolted upon the tops of the channel-beams 5 of the bolster 4: and to one side of the horizontal flange of the upper beam 2 upon each side of the truck. This brace-plate not only strengthens the connection between the bolster and the sides of the truck, but prevents any twisting of the truck under heavy strain. A braceplate may also be inserted, if desired, between the lower flanges of the channel-beams 5 and the horizontal flange of each of the side beams 3, as indicated in dotted lines at 15 in Fig. 1.

As shown in Figs. 5 and G of the drawings, the strengthening and binding irons joining the parts of the pedestal may be of other shapes than that shown in Figs. 1, 2, and 3 of the drawings. For instance, as shown in Fig. 5, the pedestal may be strengthened by means of angle and channel irons bolted together, or, as seen in Fig. 6, the pedestals may be bolted together and strengthened by means of T-irons.

It will be obvious that other minor changes maybe made in construction and the arrangement of the parts without departing from the spirit of the invention.

It will be apparent that my improved truck is exceedingly simple in construction and yet can be made of any desired strength.

One advantage of making a truck in this manner accrues from the fact that the anglebeams and channel-beams are merehantable goods and can be bought from any rollingmill making such kind of material. It therefore forms a cheap material of which to construct a ear-truck.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A car-truck comprising a bolster and sides secured thereto, the said sides being formed of angle-beams having their vertical webs adjacent to each other, the said beams being bent at their ends to form pedestals for the journal-boxes,substantially as described.

2. A car-truck comprising a bolster and sides secured thereto, the said sides being composed of angle-beams, the upper anglebeams having their horizontal webs uppermost, the said beams forming the outer mem-' bers ofthe truck-pedestals, while the lower angle-beams have their vertical webs uppermost and form the inner members of the said pedestals, substantially as described.

3. A car-truck comprising a bolster formed of channel-irons and sides formed of angleirons, the said side angle-irons having their vertical webs touch each other except at the ends where they are separated and bent to form the outer and inner members of the truck-pedestals, substantially as described.

4. A truck comprising a bolster formed of channel-irons, the Webs of the said channelirons being extended beyond the end of the flanges and bent at an angle, whereby they may be bolted to the sides of the truck, and angle-beams bolted to the said bolster for forming the sides of the truck, the ends of the said angle-beams being bent to make pedestals for the truck, substantially as described.

5. In a car-truck, the combination with a bolster,of sides secured thereto comprising angle-beams having their vertical flanges wider than their horizontal flanges and placed together, the ends of the said angle-beams being bent to form the pedestals of the said truck, substantially as described.

6. In a car-truck, the combination with a bolster, of sides secured thereto, the said sides comprising angle-beams suitably secured together, the lower edges of the vertical webs of the upper beams resting upon the upper edges of the vertical webs of the lower beams, and the ends of the said beams being spread apart to form pedestals for the journal-boxes, substantially as described.

7. 'In a car-truck, the combination with a suitable bolster, of sides secured thereto, the said sides comprising angle-irons separated at their ends to form the inner and outer members of the truck-pedestals, angle-irons bolted to the vertical webs of said side anglebeams to bind them together and form bearings for the journal-boxes in the pedestals, and brace or tie bars connecting the lower ends of the truck-pedestals, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

RICHARD IV. OSVVALD.
