CAR-TRUCK.

Specification of Letters Patent.

Patented Nov. 1%, 1915.

Application filed November 7, 1910. Serial No. 591,629.

To aZZ whom it may concern:

Be it known that 1, CHARLES A. LIND- s'rnoia, a citizen of the United States, residing at No. 138 Stratford avenue, Pittsburgh, E. E., 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. 7

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

Trucks of the Fox type comprise essen tially rigid side frames which, at their central portions, support the truck bolsters or transoms, or both, and which transmit the load therefrom to the car axles through the medium of yokes or U-shaped pedestals at the ends of the rigid side frames and which pedestals receive and are supported by springs mounted on the axle journal boxes, said pedestals also forming a bearing in which the journal boxes slide vertically- Usually and preferably side frames are made by pressing steel plates, but sometimes they are built up of plates and commercial sections.

Fox trucks have been extensively used, especially for railway freight cars and locomotive tenders, the tender trucks differing from the freight car trucks principally in the provisionsfor the tender truck of a movable truck bolster mounted between truck transoms and elliptical bolster supporting springs projecting through perforations in the truck side frames, while the Fox truck for freight cars ordinarily has no movable bolster, its center bearing plate being mounted directly on rigid transoms extendingfrom side frame to side frame. Hence, also, the Fox freight car truck has no elliptical springs projecting through the side frames.

In both freight car and tender Fox trucks, there are helical springs located between the pedestals and the tops of the journal boxes. The tender trucks are provided with the additional elliptical springs to make the truck more flexible and adapt it to compensate for the great variation in load carried by a locomotive tendon-due to consumption of fuel and water, so that no matter what the load on the tender is, shocks incidental to travel are absorbed.

An example of the Fox type of freight car truck is illustrated in Patent No. 468,146, granted to D. L. Barnes, Feb. 2, 1892; an example of the Fox type of truck espeorally adapted for locomotive tenders is found in Patent No. 505,159, granted to S. Fox, Sept. 19, 1893; both of these patents show ing side frames of pressed steel. An example of abuilt-u'p side frame in this type of truck is found in the patent to C. T. Schoen, No. 553,431, granted Jan. 21, 1896.

A specific obj ect of the present invention is to strengthen the side frame of the Fox type of truck to adapt the truck for use under railway rolling stock of greater capacity and weight without increase in proportions of the truck.

The invention will be described and illustrated in connection with What has been above described as especially adapted for use as a tender truck, but when described it will be readily appreciated that the improvements are equally applicable to all trucks of the Fox or similar type. 'Only so much of a Fox truck will be described as is necessary to illustrate the invention, reference 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 the Fox truck. Fig. 2 is a sectional rear elevation of the same. Fig. 3 is a sectional plan view of half of the same. Fig. 4 is a detail face view of one of the truck pedestals. Fig. 5 is an edge view of the same. Fig. 6 is a vertical section of the same on the line 6-6 of Fig. 4. Fig. 7 is a bottom plan view of the pedestal. Fig. 8 is a horizontal section on the line 88 of Fig. 4. Fig. 9' is a like view on the line 9-9 of Fig. 4 andv through the pedestal bolt. Fig. 10 is a side elevation of the pedestal bolt bracket. Fig.

' 11 is a top plan view of the same. Fig. 12

is a bottom plan view of the same. Fig. 13 is an outer end view of thesame. Fig. 14 is a plan view of the pedestal brace. Fig. 15 isa longitudinal edge view of the same. Figs. 16 and 17 are opposite end views of the same, and Fig. 18' is a sectional view of the same.

Referring now in detail to the drawings: 1 represents the side frame of what is known as a Fox type of truck, which type of that the brace bracket is by its lower flange riveted to the under side of the lower side or edge of the side frame 1, and by its vertical flange is riveted to the outer face of the side frame 1, and also to the lower angle 5 on the inner face of the frame 1. This brings the lower angle 5, which is a tension member, into play in restraining separation of the lower ends of the pedestal, and into compression in restraining contraction of the lower ends of the pedestal.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a car truck having a side plate, a pedestal at one end, a pedestal brace bracket having a thickened bearing portion and a pedestal brace adapted to abut the inner side of the column portion of the pedestal and to embrace the thickened portion of said bracket to restrain the column against both contraction and separation.

2. A pedestal brace adapted to embrace one of the column portions of said pedestal, and to partly embrace the other of said column portions of said pedestal to prevent spreading of said column portions and a bolt passed longitudinally through said pedestal brace and through said column portions.

3. In a car truck, a side plate, a pedestal in one end of said side plate, a pedestal brace bracket, laterally extending lugs on said bracket, a pedestal brace, one end of said pedestal brace being adapted to engage the pedestal column and said lugs, the other end of said pedestal brace being adapted to embrace the other pedestal column.

l. In a car truck, a side plate, a pedestal in one end of said side plate, a pedestal brace bracket, a pedestal brace, one end of said pedestal brace being adapted to engage the pedestal. column and brace bracket, the other end of said pedestal brace, being adapted to embrace the other pedestal column, and a bolt passing longitudinally through said pedestal brace and through said pedestal columns and pedestal brace bracket.

5. In a car truck, a side plate having in tegral flanges, a side plate reinforcement consisting of braces secured to said side plate near to its upper and lower flanges respectively and at its central or load receiving portion only, a pedestal in one end of said side plate, and a pedestal brace adapted to embrace one column of said pedestal and to engage the other column of said pedestal, and a bolt passed longitudinally through said pedestal and columns.

6. In a car truck, a side plate, a brace bracket secured to said side plate, lugs on said brace bracket, and a pedestal brace adapted to engage said lugs and pedestal.

'Tln a car truck, a side plate, a brace bracket secured to said side plate, laterally extending lugs on said brace bracket, and a pedestal brace adapted to engage said lugs and pedestal.

8. The combination with a car truck pedestal, of a pedestal brace, said brace being formed with jaws at one end and with an opening at the other end.

9. lhe combination with a. car truck pedestal, of a pedestal brace, said brace be ing formed with jaws at one end and with an opening at the other end, said jaws projecting toward each other.

10. The combination with a car truck ped estal, of a pedestal brace, said brace being formed with jaws at one endand with an opening at the other end, said jaws haying rounded outer ends.

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