To all wi'wm/ it 721a concern.-

Bc'it known that I, ETHAN I. Dorms-a citizen ot the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in BolsterConstructions iorCars, of Which the following is a specification This invention relates to the construction of bolsters for cars, and although it is shown and described in connection with a car-body -2o anchors passing beneath the outer having asloping floor or bottom and although it s especially adapted to such use obviously it may be employed in any type of car.

The invention involves several novel ieai turcs, among which may be mentioned the use of an'inte ral strut and combined spacer or fillet for the center sills in combination with one or more transverse tensionrods socured at their outer ends to angle-caps or lower ends of the body-bolster and side sills and resting on the combined strut and spacer. These tension-rods in my structure replace the usual tension-plate and have the advantages over the latter that easily removed or putin place as desired withoutcutting a single rivet, that they'are cheaper than the customary plate, and that they are arranged to perform their Function 0 more advantageously, since they extend over a longer span than the tension-plates do. ,As an additional feature .l: provide a bellied plate extending longitudinally. of thebolster, riveted to the above-mentioned strut and secured to the bottom of the car-body by means 01 rivets and an angle-bar running along its upper edge. This plate acts, as will be obvious to those skilled. in the art, as a strut or support for the bottom of the car-body. Where such a strut is used in a car having a body with a sloping bottom, the angle-bar securing the same to the bottom has its ilan es at an 'angle to correspond to the inclinatimi oi the body.

In the accompanying drawings, which form a part of the specification, .l. have illustrated one embodiment of my invention.

Figure 1 is a side elevation oi a portion ol a hopper car embodying my invention. Fig. '2 is a longitudinalvertical section on the line 2- 2 of- Fig. 3, and Fig. 3 is a transverse section on the line 3 3 of Fig. 1.

they can be quickly and l i l l l f if I having integral lu The center sills comprise spaced channelbean's 10 1 0 with their flanges extending ontwardly, the sills being held apart, yet joined together, by spacer 11, which includes arectangular lran e oi the form shown in Fig. 3, the wels oi the sills lzeingriveted to the spacer. Integral with. this spacer are outstanding llangcs 12 12, overlapping the upper llanges ol the center sills, to which they are riveted, integral with which flanges are struts 13 13,

o 14 l l, each pair of struts being spaced apart, as shown in I ig. 2. Bodybolster hean'rs 15 are attached to the center sills by means of angle-platcs l6 and to the angle side sills 17 and side stakes lb by anglehars i9. (.omprcssion angle-bars 20 are riveted to the beams 15 on oach'side near their edges, and to their (nit-standing flanges is secured comprossion-plate 21, which passes beneath the lower flanges ol' the ccntcrsills. Instead of the usual tension-plate I employ one or more tension-rods 22, passing over and resting upon the upstanding struts 13 and supporting at their outer ends the bodybolster beams and side sills. For this purpose I employ angular caps or anchors 23, each of which comprises a horizontal portion 25, extending beneath the body-bolster beam and the ilanges ol the side sill, while the upright portion 24 overlaps the vertical flange oi the side sill and tends on each side of the side stake 18, as shown in Fig. 1. Each angular cap or anchor 23 has the boss 26,

ds of tension-rods nuts on the ends of the rods holding the parts together, the rods resting on struts 13. On the accompanying drawings I have illustrated two such tension-rods; but it is ap parent that any number oi the same may be used, as conditions require.

As a support or strut for the tom of the hopper-car plate 28, riveted to the cured at its outer ends to the side stakes by means of the angles 30. The inclined lower edges of this plate are supplied with integral compression-llanges 29, is shown in Fig. 3. To connect this bellied. plate, which constitutes a strut or support for the bottomof the car, to the latter, I provide anglebar 32, which is riveted to the plate and also to the bottom of the car-body. I have shown and through which pass the on 9) sloping hot- I provide the bellied spaced lugs 14 and se- ICC described this portion of the invention as applied to a hopper-car with an inclined bottom; but it is obvious that the invention may be used in connection with car-bodies other than that shown and described.

Since the spacer, struts, and lugs are integral, it is evident that the underi'rame of the car, including the body-bolster, can be quickly assembled, owing to the small number of parts, and it will also be apparent that the tension-rods 22 may be readily put in place or removed by merely unscrewing the nuts at their outer ends, no cutting of rivets being required. It will also be obvious that my improved means for supporting the carbody above the body-bolster involves a very simple construction, which nevertheless provides suflicient strength with a minimum of weight. Instead of making plates 15 and 28 integral, as has been usual, I make the latter bellied in shape and separate from the bolster-beams, in this way saving somewhat in the weight of the parts and at the same time constructing plate 28 of a shape to effectually withstand the load or strain put upon it.

Obvious and minor mechanical changes which will suggest themselves to those skilled in the art will fall within the substance of my invention as defined. in the appended claims.

This patent is intended to embrace only so much of the disclosure made herein as is covered by the claims.
