LOGGING CAR FOR SHORT LOGS.

Application filed August 3, 1922.

To all whom it may concern:

Be it known that I, FREDERICK \V. CHRIswnLL, a citizen of the United States of America, and resident of the city of Seattle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Logging Cars for Short Logs, of which the following is a specification.

My invention particularly relates to cars which are designed for handling short length logs, although its use is not limited to such purposes.

' The principal object of my invention is to provide means whereby a standard car of the connected truck type designed for handling logs of ordinary or extra length may be converted into a car for handling two-lengths of logs and to do this by addition to the standard car of this type of parts which fit thereon as attachments without necessitating changes in the original car members, whereby the conversion of the standard car to adapt it to the new use may be quickly and easily accomplished.

My invention comprises those novel parts and combinations thereof which are shown in the accompanying drawings, describedin the specification. and particularly defined by the claims terminating the same.

In the accompanying drawings I have shown my invention in the form which is now preferred by me. 0

Figure 1 is aplan view of the central portion and one end of the body construction of a car embodying my invention, the trucks being omitted.

Figure 2 is a side elevation of the same.

Figure 3 is a side view of the end of a transverse bolster, looking from the end of the car.

Figure i is an end elevation of the same bolster. Y

Figures 5 and 6 are perspective views of two special fittings which are employed in connection with my invention.

My present invention relates particularly to such cars as are shown in my previous Patent No. 995,056, dated June 13, 1911, orin the patent to H. C. Jarvis, No. 1,415,357,

dated May 9, 1922. In these cars a longitudinal central sill 1 forms the backbone of the car, and upon this adjacent the ends thereof, are securedtransverse bolsters 2.

i of the bolster.

Serial No. 579,372.

Above the bolsters, and assisting in strengthening and supporting them, are bunks 3 upon which the logs are suitably supported.

Such cars are known to the trade as connected-truck cars and are especially adapted for hauling logs of ordinary length or for logs of extra length, as has been illustrated 1111118 Jarvis patent referred to, but are not suitable for logs of length less than the distance between the bunks 3. Between the two end bunks 3, therefore, I provide two supplemental bunks 30, thus adapting it to carry half length 01' short logs. The supplemental bunks are shown as primarily secured to the central sill 1. Without further provision their ends, however, would be unsupported, and inasmuch as great strains are placed upon these ends, it is necessary to provide means for supporting them.

I have therefore provided side sills l, one for each side of the car, which support the outer ends of the intermediate bunks 30 and whlch are themselves supported from the bolsters 2. Additional bolsters. 20 may be provided, if desired, beneath the bunks 30 in order to stiffen them, but as this is a matter of engineering detail, the advisability of proyiding these may be left to the designing englneer.

In the standard car the bolsters 2 are formed with a central vertical web 21 and with stiffening flanges 22 projecting laterally from the central web adjacent the ends In order that there be no change required in the bolster itself. I have provided a pair of fittings which are supported by these flanges 22 and which cooperate to support the side sills 4. One of these fittings, 5. being that one which is intended to face the center of the car, is provided with a shelf- 51 which projects later-- ally and upon which the end of the side sill 4 is supported. Both this fitting and its companion fitting 6 are provided with spacing flanges 52 and 62. respectively. which in addition to strengthening the fittings are so arranged that they will avoid the stiffening flanges 22 of the bolster and will be supported therefrom without the necessity of bolts or the like.

The fitting 6 may be termed a washer fitting inasmuch as it is provided withapertures 63 through which a pair of truss rods 7 are passed. These truss rods pass through the fitting 6, which is at the side of the bolst towards the end of the car, through the b0 ster 2 and at opposite sides of the fitting 5, which is made narrow for this purpose. They also pass upon the opposite sides of the ends of the side sills 4, and in this manner assist in maintaining these sills in position upon the fitting 5. By tightening the turnbuckle 71 upon these truss rods 7, the sill 4 and the fittings 5 and 6 are clamped in place upon and between the bolsters 2.

I have provided a bolt 42 passing through the sill 4 and the shelf 51 for additional security. If the supplemental bolsters 20 are employed these are supported directly from the truss rods 7, or if these supplemental bolsters are not to be employed, spacer brackets will take their place.

By the use of the simple constructions shown and described, a standard car of the type named may be quickly and economically modified to carry short length logs, thus enabling the superior advantages of the connected-truck type of cars to be availed of for hauling short logs.

What I claim as my invention is:

1. A logging car including a central longitudinal sill, transverse bolsters secured thereto adjacent each end, a side sill at each side of the car,bunks extending transversely of the car intermediate said bolsters and supported at their ends upon said side sills. and means for supporting the ends of said side sills from the end bolsters.

2. A logging car including a central longitudinal sill, transverse bolsters secured thereto adjacent each end, a side sill at each side of the car, bunks extending transversely of the car intermediate said bolsters, the ends thereof being supported from the side sill, and a fitting having a shelf and adapted to be supported from the ends of the end bolsters, the ends of said side sills being supported upon the said shelf.

3. In a logging car including a central longitudinal sill, the combination with bolsters secured thereon adjacent each end, and
