Specificationof Letterslatent. t t b 14, 1922 Application filed March 259, 1921., Serial No. 456,551.

To all whom it may concern:

Be it known that I, FREDERICK IV. CHRIS- W'ELL, a citizen of the United States of America, and resident of the county .of King and State of Washington, have invented certain new and useful Improvements in Railway Cars, of which the following is a specification.

My invention relates to railroad cars and cons1sts of a car the purpose of which is first to carry heavy loads and second to have such strength in a transverse direction that it may be able to resist the side strains due to hauling heavy loads thereon and, further, one having such a construetion of its floorand particularly of the outer edges of the floor, that it will be much easier to draw any heavy body thereon, as a piece of heavy machinery, than is possible with cars of the usual construction. My invention further consists of a construction whereby astrongiandsimple form of stake may be provided which is readily attachable to and detachable from the car.

The features of my invention will be hereinafter described and the parts thereof:

which I believe to be novel and upon which I desire to secure a patent will be p articularly defined byv the claims terminating thi. specification.

In the accompanying drawings I have. shown and will now describe the type of construction which I now prefer to use.

Figure '1 is a side elevation of a half length of a car built in accordance with my invention.

Figure 2 is an end view of the same car, one-half thereof being in sectiontalren at a point towards the center of the'car.

Figure 3 is a transverse section through one side edge of the car, showing the manner of securing the stake thereto The particular service for which the present car has been designed is the transportation from place to placeofheavy logging engines which are mounted upon skids. It is, of course, obvious that it is as well adapted for the loading and handling of other heavy bodies of analogous character. I will, however, describe it as employed in loading and transporting such logging engines, it being understood that any other use to which it is capable of being put is also contemplated.

The frame construction of the car to the city of Seattle, in

which may invention has been applied is heavy, as it is designed for carrying verv heavy loads. The present invention is, however, not concerned with the type of construction of the car frame except in such respects as are specifically pointed out. The car as here illustrated has two heavy side beams or sills 1, which are made of a built up construction. It is also-provided with other longitudinal sillsand these are bound together by suitable cross sills so placed and n such number as may be desired for makmg a car of the desired strength. i

In the particular use mentioned. for which this car was designed, the logging engines, mounted upon skids which employ as their main supporting members two large and long logs, are loaded upon the car usuallv from the side and by means of blocks and tackle operated by the engine itself. these engines so mounted upon their skids are very heavy, often weighing ninety tons or more, this manner of loading is liable to plates are securely fixed to the car framing and preferably extend over the entire floor of the car. Such platesforma 'very rigid and strong stiffening web to resist any lat eral distortion of the carbody. Atthe same time theyform a smooth and durablesurface upon which to carry and to slide the engine and its skid orany other heavy object which may be handled upon the car.

In order tdfacilitate drawing the-engine and its skid upon the car, the edges of the floor plates 2 are projected beyondthe side edge of the frame and such projecting edge is turned down in a curve, as is shown'at 20, thus forming a rounded edge ofa shape and size which will prevent digging into the bottom f the skids when loading the engines.

In the ordinary platform car the outer edges of the floor form a right angle. In attempting to draw an engine mounted upon its skid upon a car of this sort, the sharp edge of the car floor is apt to dig into the bottom of the skid logs and thereby'ofler a serious resistance against movement 9f th floor skid. This is particularly true if the engine and its skid prior to loading are supported upon a surface below the level of the car floor. However, with an edge rounded, as is most clearly shown in Figures 2 and 3, a skid striking such an edge has a smooth rounded edge to slide over, thus very greatly reducing the resistance and also obviating any injury to the bottom surface of the sln'd.

The rounded edge of the floor plate is shown in the drawings as extending from one end of the car to the other. This rounded edge may also be carried over the ends of the car as shown at 21, if desired. This, however, may in some cases be unnecessary. I contemplate so constructing it whenever this is desired.

V I have shown filler blocks as interposed between the projecting edges of the floor and the outer side surface of the sills, which materially strengthen and support such edges and prevent deformation. These consist of a series of blocks 3 in the form of castings which may be secured against the side surface of the sills 1 and areshaped to conform to the under surface of the floor plate. I have also shown an angle bar, as 4, which is used to connect the floor plate to the sill, being located in the angle between the two.

"Where such anangle bar is employed the filler plates will be recessed at the back to accommodate themselves to the outline of said angle bars. These angle bars are provided with bracket webs 80 which also materially stiffen them. As shown in Figure 1 these filler blocks do not extend entirely to the end of the car. This is, however5 a matter of choice. The loading of a donkey engine upon the car will usually occur at the center point of the length of the car. will first be drawn upon the car and will then be turned so as to extend in the same direction as the car.

Such a car should be provided with means for detachably securing stakes thereto which may be put in positionafter the donkey engine has been loaded and which will prevent side movement of the engine upon \the car For this purpose I provide a car made in accordance with m 7 invention with four stakes and means for securing them. To this end one of the filler blocks 3, located towards each end of each, side of the car, is

provided with a special web, as 31, upon which is pivoted a stake-retaining link 5.

Associated with this is an arm 50 which extends downward and has its lower end turned somewhat outwardly as is clearly shown in Figures 2 and 3. This forms a seat or stop for the lower end of the stake. The stake which it is contemplated will be used for this purpose is one which has a flat inner side surface, that is the side surface which is next to the car.

A convenient and eflicient form of stake is made from a short piece of railroad rail placed with its base inward. Such a stake in Figure 2 and by dotted lines in Figure 3. When the stake is not in use the retain-v ing link 5 will hang down as is shown at the left side of Figure 2 and in full lines in Figure 3.

Cars of this construction have proved to be excellently adapted for the particular purpose named. They are not deformedby the strains applied thereto while loading and they have the strength to safely carry the heavy loads applied even over rough tracks. 'They also facilitate loading so that.

the-time required for loading and unloading is very much reduced. 7 l

W hat I clann as myinvention is 1. A platform car having a body frame.

and metal floor plates secured to said frame to form a horizontal stiffening web and at the edges of the car body curving downwardly to form rounded edges thereby facilitatlng drawing heavy loads thereon.

2. A platform car having a body frame and heavy metal plates secured thereto to form a floor, said plates extending beyond the framing at the car sides and being rounded down to form a smooth rounded edge and filler blocks between said project,- ing edge and the outer sill of theframe.

igned at Seattle. King County, ash ington, this 7th day of March, 1921.
