ARTHUR LIPSCHUTZ, OF ST. LOUIS, MISSOURI.

TRUCK AND BODY B OLSTER.

SPECIFICATION forming part of Letters Patent No. 738,213, dated September 8, I903.

Application filed January 24,1903. Serial No. 140,361. (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR LIPSCHUTZ, a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Truck and Body Bolsters, of which the following is a specification.

My invention relates to truck and body bolsters for railroad-cars; and the object of my invention is to provide a strong all-metal bolster of less weight and cost than the bolsters which are now in use.

A particular object of my invention is to provide a truck or body bolster in which ordinary rolled or structural steel shapessuch as channelbars, I-beams, and the like-may be employed without alteration in shape.

My invention primarily consists in the combination with a channel I or otherbeam preferably of commercial cross-section, with a pressed-metal truss attached to the bottom of the beam and therewith forming a complete bolster,which in elevation corresponds closely to the accepted theoretical bolster outline; and, further, my invention consists in a car element wherein the flange of the pressed truss portion is turned inwardly, giving the bolster a substantial Z shape in cross-section of great strength; and my invention further consists of a new article of manufacture and also in various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a perspective view of a beam and its reinforcing truss embodying my invention. Fig. 2 is an elevation of a truck-bolster. Fig. 3 is an enlarged section on the line :0 x of Fig. 2. Fig. 4 is an enlarged section on the line y y of Fig. 2; and Fig. 5 is aview similar to Fig. 3, showing the beam construction of the car element.

The most practical form of my invention includes a rolled channel 2, Fig. 3, or a rolled 'I-beam 3, Fig. 5, these being commercial shapes which can be readily obtained in various sizes as required in the manufacture of parts for cars of different carrying capacities.

Other and different beams and shapes may be utilized within the scope of my invention, though not economically adapted thereto. The gist of my invention resides in the combination of the beam 2 or 3 with the truss 4, attached to the lower flange of the beam; and my invention also resides in the arrangement of the beam and the truss with their webs or vertical portions in the same vertical plane, whereby maximum strength is secured in a minimum weight of material. The truss that I prefer to employ is Z shaped in cross-section and is an article that is pressed from sheet-steel. In elevation the device is trussshaped, and the lower flange 5 follows the truss outline. The upper flange 6, which is riveted to the lower flange of the uniform section-beam, extends oppositely to the flange 5, and its ends 6 are preferably extended outwardly beyond the upper ends of the inclined portions 5 of the lower flange. The rolled channel or otherbeam and the pressed flanged truss when firmly riveted together constitute the complete device. This upon the addition of suitable column-guides, such as '7 preferably of unequal thickness, may be used as a bolster for a car. here great strength is required, I prefer the I-beam form of the bolster, as shown in Fig. 4:. In the case of a truck-bolster, the truck-center 8 is applied to the top flange of the beam 2 3, while in a body-bolster the truck-center would be applied to the bottom flange 5 of the truss 4:. I prefer that the truck-center shall overhang the web of the beam, as indicated in Fig. 3, the flanges of the beam being perforated to receive the center bolt 9.

10 is an overhanging bracket to assist in supporting the center plate 8.

As it is obvious that numerous modifications of my invention and also additions thereto will readily suggest themselves to one skilled in the art, I do not confine the invention to the specific constructions and combinations of parts herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The element or bolster, comprising the beam of uniform cross-section,incombination,

with the individual truss thereof, of varying depth and cross-section; substantially as described.

2. The element or bolster, comprising the rolled structural beam of suitable length having a vertical web and top and bottom flanges, in combination, with the individual pressed plate-metal truss thereof secured to one of said flanges; substantially as described.

3. The element or bolster, comprising the rolled structural-steel beam of suitable length and cross-section, in combination, with the pressed-steel truss, Z-shaped in cross-section and having its upper flange riveted to the lower flange of said beam; substantially as described.

4. The element or bolster, comprising the beam, in combination, with the pressed-steel truss of less length and having an upper flange riveted to the lower flange of said beam; substantially as described.

5. The element or bolster comprising the flanged beam, in combinatiomwith the flanged pressed-metal truss, the webs of said beam and truss occupying the same vertical plane and said truss having its upper flange riveted to the lower flange of said beam; substantially as described.

6. The new article of manufacture, consisting in the beam-truss, comprising the web 4, the top flange 6, and the lower flange 5, having inclined portions following the outline of the truss; substantially as described.

7. The new article of manufacture, consisting in the beam-truss, comprising the web 4, the top flange 6, and the lower flange 5, said flange (3 being longer than the flange 5, having inclined portions following the outline of the truss; substantially as described.

8. The bolster comprising the rolled-metal beam having a vertical Web, in combination, with the'individual pressed-metal truss riveted to one of the flanges of said beam, and the. trucks center overhanging the flange whereon it is secured; substantially as described.

9. The bolster comprising the rolled structural beam of suitable length, in combination, with the individual pressed metal truss having lateral flanges, the longest of which is riveted to the flange of said beam, the overhang bracket and the truck-center riveted to the web and flange of the bolster, substantially as described.

In witness whereof I have hereunto set my hand, this 17th day of January, 1903, at St. Louis, Missouri.

ARTHUR LIPSCIIUTZ.

In presence of T. G. \VoLFF, CHAS. A. LIDDLE.
