1,101,101. Specification of letters Patent Patented June 2?, 12914:. Application filed March 23, 1914. Serial No. 826,614.

frame car may consist of an end sill 10, side sills 11, intermediate sills 12, and center sills 13. Connecting the various sills is a body bolster 14., of any approved form. lin Fig. 55 2 only the top plate of the body bolster is shown. Mounted above the body bolster and beneath the sills is a casting consisting of a horizontal shelf 15, having a notch 16, therein, fitting snugly the top plate 1d of 60 the body bolster; a vertical web 17, from which may be projected a truss rod bracket 18. The right angled members may be strengthened by suitable webs 19, 20. Provision is made for a large number of fasten- 65 ing bolts 21, 22, through the sill and bolster respectively.

, By the use of a device such as shown the sills are greatly strengthened at the needed point and the life of wooden underframe 70 cars is increased.

An advantage in a device such as shown is in that it may be applied to cars which have already been built thus avoiding the necessity of splicing or reinforcing such sills 75 which have been damaged.

1 claim:

1. In a car underframe, the combination of wooden center and side sills, metallic cross members, and metallic reinforcing 80 members contacting said cross members and underlying said center and side sills, said reinforcing members and said cross members having interlocking engagement an said side sills being secured to said reinforc- 85 ing members by a plurality of bolts, whereby an extensive strain-resisting connection is formed between the sills and the crossmembers, substantially as described.

2. In a car underframe, the combination 90 of wooden side sills, metallic cross-bearers, and metallic reinforcing members having interlocking engagement with said cross bearers and underlying said sills, and a plurality of bolts connecting said reinforcing mein- 95 bers to said sills, substantially as described.

l/VALTER A. STEARNS.

To all whom it may concern:

Be it known that I, lVALrnR A. S'rnanns, a citizen of the United States, and resident of Hammond, in the cotmty of Lake and 5 State of Indiana, have invented certain new and useful Improvements in Gar-Sill Bearings, of which the following is a specification.

My invention relates to railway cars and has particular reference to a novel metallic strengthening device for use in connection with wooden underframes of cars.

1t is a well known fact that there are many designs of cars in service and many cars being built having wooden underframes, that is, longitudinal wooden sill members. Usually such cars are provided with a metallic body bolster and cross bearers and as many of the shocks and strains of service are transmitted to the car body through the metal body bolster, the sills at the point of connection are frequently damaged, the bolts pulling out or becoming loose, etc. This difficulty, of course, is due to the fact that the metal composing the bolster or cross bearers possesses much greater resistance to destruction or fracture than the wooden sills.

It is a object of my invention therefore to strengthen the connection between the sills and bolster by providing an increase bearing. This is secured by locating above the body bolster a bracket or saddle of considerably greater length than the width of the bolster, such strengthening member being suitably secured to the body bolster and providing for an extended bearing on the sill as well as a plurality of connections to the sill. Such a device also readily accommodates a gearing for the car truss rods.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is a plan view of a fragmentary portion of a wooden underframe car having my improvement applied thereto; Fig. 2 is a section on the line 2-2 of Fig. 1, and, Fig. 3 is an enlarged section on the line 3-3 of Fig. 1, the bolster being omitted, Referring more particularly to the drawings it will be see that a wooden under- WVitnesses J.
