Application filed June 17, 1918. Serial No. 240,312.

To all whom it may concern:

Be it known that 1, JOHN C. H. LUBKEN, a cltizen of the United States, residing in the borough of lVestmont,iu the county of (ambr1a and State of Pennsylvania, (whose post-office address is J ohnstown, Pennsylvan1a,) have invented certain new and useful Improvements in Mining-Cars; and I do hereby declare the following to be a full, clear, and exact description, such as will enable others skilled' in the art to which it appertains to make and use the same. My invention relates to cars used in minmg or other industries, and particularly to those that are made up into trains and hauled by a motor, cable, or otherwise, and one of the objects of my invention is to provide a car that is well adapted to this service and constructedwith particular reference to withstanding the pulling and bumping shocks. to which such cars are subjected.

My car body is preferably made of sheet or plate metal which is pressed into shape with a flat bottom and with a central longitudinal ridge formed integral in the bottom portion and projecting upwardly therefrom, the upper portions of the car sides being flaring and provided with a rounded bead at their upper edges to strengthen and stiffen the same,- and provided with separate end pieces which are secured to the sides and bottom by flanges formed integral with said end portions so that in case of damage of any one portion, the damaged one alone need be replaced.-

One of the particular features of my invention relates to reinforcing the bottom by the insertion of a longitudinal sill of timber, inserted-and fitted within the up-pressed metal ridge of the car bottom and secured to the car bottom by rivets or bolts, the ends of the sill being provided with bumper blocks,

preferably made of pressed steel and with a continuous draw-bar secured thereto, whereby these cars, when formed into a train, have a substantially continuous draw-bar and center sill extending throughout the length of the train, thereby adapting them to fully withstand any pulling or bumping shocks to which they may be subjected.

Having thus given a general description of my invention, I will now, in order to "make the matter more clear, refer to the annexed sheet of drawings, which forms part of this specification, and in which like characters refer to like parts:

Figure 1 is a top plan view of my'improved mining car;

Fig. 2 is a side elevation of the mining car, with the right-hand portion of the car shown in vertical sectional elevation on the longitudinal center line of the car;

Fig. 3 is a vertical transverse sectional elevation taken on the line IIIHI of i 2 Fig. l, is a side elevation of one of the bumper blocks;

Fig. 5 is a top plan view of the bumper block; and

Fig. 6 is a top plan view of one of the pressed metal spacing members. Referring now to the characters of reference on the drawings: 1 represents the car body in general, 2 the sides thereof, the

upper portions of which are shown as flaring and provided with a reinforcing head on the upper margin thereof, 3 is the car bottom, 4 is a central longitudinal ridge shown as of channel section formed integral with the bottom plate portion of the car body,-5 are the ends of the car which, as shown, are provided with flanges whereby they are secured to the body portion, 6 are reinforcing plates on the inside of the car floor adapted to strengthen the same at and near the points of application of the axles to which the load is transmitted, 7 are angles applied transversely to .the bottom of the car to further strengthen and stiffen the same, 8 is a drawbar composed of a flat bar of iron or steel applied and secured to the top portion of the up-pi'essed center sill, as illustrated, and provided with holes 10, adapted to receive the coupling pins 11 and 12. These up-bent ends 9 of the continuous draw-bar are spaced apart from the bumper so as to provide room for the coupling link between the same, as

i 'come together and also provided with an upper flanged portion 17 and a bottom flange 18, the bottom flange being wider and provided with holes adapted to receive bolts, as illustrated, to secure it to the metal end of the car. 19 is a pressed metal spacing member located between the bent-up end portion 9 of the metal draw-bar and the upper surface of the flange 17 of the bumper block and all secured together by bolts, as shown, this spacing member being provided with the flanged edge 20,"as illustrated.

On account of the addition of the wooden center sill to the bottom of the metal car and preferably in the approximately rectangular space formed by the up-pressed longitudinal projection of the floor plate and by securing said wooden sill to the metal body, I provide a combination of wood and metal which is very well adapted to give the necessary strength to the structure and "to ably Withstand any pulling or bufling stresses to which it may be sub ected. The Wooden sill to reinforce the metal structure is particularly useful in withstanding heavy bufling stresses, as the wood has a certain amount of elasticity, butits modulus of elasticity is much lower than that of steel and its reactive effect is less on account of its structure so that when a heavy shock comes upon the sill in the attempt to compress or buckle it, this shock is largely absorbed by the wooden sill and the reaction given back gradually to a much lesser extent. In view of this, the addition of the wooden sill is particularly effective and has been so proven by actual use.

Although I have described and illustrated my invention in considerable detail, I do not wish to be limited to the exact and specific details thereof as shown and described,

but may use such modifications in, substitutions for, or equivalents-thereof, asarecmbraced within the scope of my invention, or as pointed out in the claims.

Having thus described by invention, what I, claim and desire to secure by Letters Patent is 1. The combination With'a metal car body of a wooden longitudinal center-sill partially surrounded by and secured thereto and adapted to strengthen and reinforce the same against stresses.

2. In a metal car provided with an upwardly projecting longitudinally extending central portion, a wooden sill seated within therefrom and exten said projection and secured to the adjacent metal construction.

3. A car body composed ofmetal plate provided with an upwardly and longitudinally extending portion, a wooden center sill seated within the recess of said portion and secured to the car structure.

4. In a car body, a metallic floor plate provided'with an integral portion projecting ing. longitudinally of the carnear the center thereof, a wooden center sill seated Within the recess formed by said projecting portion and secured to the car structure.

5. A metal car body provided with a flanged portion and an upper flanged portion which are substantially parallel, a bumper portion which is approximately at right angles to said flanges and means for securing same to the center sill and to the car structure.

7. A metal car provided with a wooden center sill extending longitudinally thereof, a pressed steel bumper plate provided vwith holes to receive the coupling pin, on each end of said sill, said plate comprising a lower flanged portion and an upper flanged portion spaced apart and substantially parallel, a bumper portion joining said flanges, and means for securing same to the center sill and to the car structure.

8. In a metal car, a wooden center sill extending longitudinally thereof and projecting outwardly from the end portions, a pressed steel bumper plate secured on each end of said sill and provided with holesto receive the coupling pin; means for securing same to the car structure; a longitudinally extending'draW-bar secured to the car structure, the ends of same being offset and spaced apart from said bumpers and means interposed between said draw-bar and said bumpers to maintain said spacing.

In testimony whereof I hereunto aflix my signature.

JOHN C. H. LUBKEN.
