CAR-TRUCK.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed December 29, 1915. Serial No. 69,183.

To all whom it may concern:

Be it known that I, FELIX KOCH, a citizen of the United States, residing at No. 62 North Harrison avenue, Bellevue, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

An object of the present invention is to provide improvements in what is known to railway engineers as the F ox type of truck for railway rolling stock, or in trucks of similar type, and particularly to increase the strength of the truck without increasing its size or materially changing its proportions.

Railway cars have increased in capacity from, say 60,000 lbs. in 1900 to 120,000 lbs. or more, in 1915, but little attention has been given to the strengthening of the Fox type of truck, the same having been used practically without change in construction notwithstanding such increase in car capacity, one of the reasons therefor being that the side frames of these trucks are formed by pressing sheet metal to shape in expendies useless.

Anexample of the Fox type of freight car truck is illustrated in United States Patent No. 168,146, granted to D. L. Barnes, February 2nd, 1892. An example of the Fox type of truck especially adapted for locomotive tenders is found in UnitedStates Patent No. 505,159, granted to S. Fox, September 19th, 1893, both of these patents illustrating trucks in which the side frames are formed of pressed steel.

Trucks of the Fox type are constructed with rigid side frames which at theircentral portions support the transoms, the side frames transmitting the load from the transoms to the car axles through the medium of U shaped pedestals formed at the ends of the rigid side frames, which pedestals receive and are supported by springs mounted on the axle journal boxes, the legs of said pedestals also forming hearings in which the journal boxes slide vertically. Somean example of such built-up side frame be- 553A31, granted to C. T. Sc'hoen, January 21st, 1896.

A specific object of the present invention is to strengthen the side frame of the FoX type of truck in such a manner as to adapt it for use in connection with railway rolling stock of the increased capacity hereinbefore referred to without changing the contour of the truck frame or materially increasing the general dimensions and proportions of the truck.

This invention is illustrated and described in its adaptation for use as a freight car truck, but without special description it will be readily appreciated that the improvementsare equally applicable to all trucks of the Fox or similar type when adapted for use in connection with locomotive tenders. Only so much of the Fox truck will be described as is necessary to illustrate this particular invention, references being had to the accompanying drawings in which like characters refer to like parts, and in which:

Figure 1 is a sectional side elevation'of a Fox truck, Fig. 2 is a sectional plan view of thesame, and Figs. 3 and 1 are vertical sections taken on lines 3-3 and 11 respectively of Fig. 1. Figs. 5, 6 and 7 are Seetional views taken on line 55 of Fig.1, showing modifications of the construction of the upper portion of the side frame.

Referring now in detail to the drawings, 1 indicates the side frame of what is known as the Fox type of truck, this side frame being similar in contour to the side frames illustrated in the patents hereinbefore referred to. The plate forming the side frame 1 is bent inwardly along portions of its upbuilt up of plates and commercial sections, 7

edge, and at its end edges in the manner shown at 5 in Fig. 4 of the drawings, and also bent inwardly toward the longitudinal center line of the truck at points indicated by 6, ,6 in Figs. 1 and 2 of the drawings. When the plates 1 and 41 are placed together it will be seen that the central portions 7 and 8 respectively contact with each other and may be secured together by rivets or other suitable means. It will also be apparent that as the result of the bending of plates 1 and st in the manner above described, there will be a space 9 intervening between the end portions of said plates, said space being taken up and maintained in the pedestal portion of the frame by projecting portions 10 on the pedestal members 11, which are secured. in position between the frame members 1 and 4, by any suitable means.

The space intervening between the upper edge portions and end edge portions is shown in Fig. t as being taken up and maintained by an auxiliary or re-inforcing member 12, which may be of angular, or any suitable section, and in Fig. 5 as of T section.

Fig. 6 shows a modification of the last described construction in which the edge portions of the frame plates 1 and 4. are bent toward each other a sufficient distance to make contact between them, the reinforcing member 13 of Z, or other suitable section is secured to said edge portions by rivets passing through the reinforcing member and edge portions of the frame members.

Fig. 7 illustrates a further modification in which the edge portions of frame plates 1 and 4t are spread farther apart or bent away from each other a sufficient distance to admit of the insertion therebetween of a reinforcing member 14:, of channel or other suitable section; said member being secured in' position by suitable means passing through the edge portions and re-inforcing member.

15 indicates the transoms or cross-tie members which serve to tie together the frame members 1 and etforming the opposite sides of the truck, these transom members being braced and stiffened by the usual crossbrace members 16 and the center brace member 17.

18 indicates a gusset member adapted to assist in securing together and bracing the transom members 15, the side frame mem bers 1 and 1, and the reinforcing members, the gusset member being secured to the upper flange of the transom member 15, and to the flange of the re-inforcing member.

Further description of the essential parts of the Fox type of truck will be found in either of the aforementioned patents, and hence features which are not pertinent to the present invention are not described herein.

Having thus described the invention,

end edges of said plates, and a pedestal 7 member secured between the spaced end portions of said plates.

2. In a car truck, a side frame comprising a plurality of connected plates, the ends of said plates being bent laterally of the side frame in opposite directions to form a re cess, an angular member secured along the top edges of said plates, and a pedestal member extending between and secured to said plates within said recess.

3. In a car truck, a side frame comprising a plurality of connected plates, one of said plates being offset outwardly at its ends, and the other of said plates being offset inwardly at its ends, a reinforcing member secured along the top and end edges of said plates, and pedestal members secured ,between the offset portions of said ends.

4. In a car truck, a side frame comprising a plurality of connected plates extending the full length of said truck, a pedestal member secured to said plates, said plates being offset laterally of the side frameto form a recess for the reception of said pedestal member, and a reinforcing member secured to the top edges of said plates.

5. In a car truck, a side frame comprising a plurality of plates extending the full length of said truck, and a reinforcing member secured along the top and end edge portions of said plates.

6. In a car truck, a side frame comprising a plurality of plates extending the full length of said truck, portions of the ends of said plates being spaced apart, pedestals extending between and secured to said end portions, and a reinforcing member secured to the top and end edges of said plates.

7. In a car truck, a side frame composed of two plates, portions of said plates being secured together in contact with each other, the other portions being spaced apart, and an angular re-inforcing member inserted between and secured to said spaced apart portions, said member extending for the full length of said plates.

' 8. In a car truck, a side frame composed of two plates, portions of said plates being secured together in contact with each other, the other portions being spaced apart, a flanged re-inforcing member secured between said spaced apart portions, and a gusset plate secured to the flange-of said reinforcing member.

9. In a car truck, side frames, each composed of two plates, portions of said plates being secured together in contact with each other, the other portions being spaced apart,

a re-inforcing member secured between said spaced apart portions, transoms connecting the side frames, and gusset members connecting said re-inforcing members and transoms.

10. In a car truck, a side frame comprising a plurality of plates extending the full length of said truck and having pedestal openings in their ends, said plates being oifset around said openings, and pedestal members extending between and secured to said offset portions.

11. In a car truck, a side frame composed wholly of two plates, the end portions of said plates being ofi'set laterally of the truck in opposite directions, and pedestals extending between and secured to the offset portions of said plates.

12. In a car truck, a side frame comprising a plurality of connected plates extending the full length of said truck, the end portions of said plates being offset laterally of the truck in opposite directions, pedestals secured between the end portions of said plates, and a reinforcing member secured along the top and end edges of said plates.
