CONCRETE CAR.

Application filed August 27,1920. Serial No. 406,379.

To all whom it may concern:

Be it known that I, JOSEPH B. STRAUSS, a citizen of the United States, residing at Chicago, in'the county of Cook and State of illinois, have invented a certain new and useful Improvement in Concrete Cars, of which the followingis a specification.

This invention'relates to concrete cars and has for its objectto provide a new and improved device of this description. The invention has among other objects, to provide a car having a concrete body formed to stand the strains andstresses and rough "uses to which cars are subjected, and which shall at the same time, be cheap to construct and comparatively light in weight. The invention has other objects which are more clearly pointed out in the following. description.

' Referring now to the accompanying drawings which show the construction embody ing my invention,

Referring now to 'the dra wiilgs, have;

shown a construction where areinforced concrete body is made separate from the metal underframe and is then placed upon this underframe and fastened thereto. The metal underframe may be of any desired construction corresponding to that made by the Master Car Builders specifications. In 2 Figure 1, I have shown the body" made of reinforced concrete and having a bottonifl, and side walls 2, and ends 3. v The bottom and side walls are preferably integral while the ends may be separate and removably attached in position if'des'ired so that ifinjured, they can be easily replaced. The side walls are provided with a' series of ribs or stakes 1, which connect with the bottom and which are provided with reinforcing metal 5. These stakes are both on the outside and inside and" are shown in detail in Figure .6. There are; inclined ribs or stakes 6, which preferably connect with, the vertical ribs or stakes 4, andwhich also contain reinforcing material. 7. The upper edges of the body. are providedwith metal frame pieces 8 which are shown as channels and these metal frame pieces are connected to the reinforcement. In Figure 7, I have illustrated one method of doing this wherein the reinforcing metal members 5 and 7 are connected "to the frame piece 8 by means of nuts 9. The stakes instead of beings-both on the outside and inside may be only on one side as shown in Figure 5, and are provided with the reinforcing metal pieces 5. These reinforcing metal pieces are tightened together by reinforcing metal 10. The bottom and sides have other metal reinforcement 12. I also prefer to provide the bottom, sides, and ends with wire mesh or net work reinforcement 13, and this reinforcement is connected with the longituddinal metal members 8 at the top and let at the bottom of the side walls and ends. The metal underframe is made up of the center sills 15 and bolsters 16, one at each end and metal cross bearers 17. The concrete body has the longitudinal metal members at the edges thereof and there are cross members 18 associated with the floor and connected with the longitudinal metal members. This connection. is made in any desired manner asby plates 19 and suitable rivets, and these cross members are also connected with the longitudinal metal members 14 of the body by suitable plates 20. The center sills are preferably made up of metal parts as illustrated in Figures '3 and 12 and 13, although any other suitable construction may be used. The ends may be integral with the sides and floor of, the body or they may be separate as'illustrated in F igure 2 where y I have shown an end 22 having the upper and lower

metal bounding members

8 and 14 and the stakes with the various reinforcing metal rods embedded in the concrete. When separate ends are used, they are arranged so that they may be removably connected with the wallsand bottom so that they can be disconnected for purposes of replacement. Suohends are provided with limiting metal members on both thetop and bottom and the other edges, these other metal members being shown at 24. These metal members are removably connected to the side walls of the car by suitable connecting pieces 38 as shown in Figures 1 and 21. I may also provide pipes 28 for fluid which may be embedded in the floor of the car and extend longitudinally and cross-wise and- I can use them aspipes and also "as reinforcing metal. These pipes may be provided for air and steam. For exam'ple, at certain times, it is desirable to heat by steam withinthe car and steam can be then sent through these pipes for that purpose. "In Figures 17 and 18, I have shown am'odified construction where there is a metal longitudinal sill 30 and metal cross bearers 31 and bolsters 32.

Figures 23 and 24 show the concrete door 39 with the metal bounding edges 40 and hinges 41. It will be noted I have here shown a construction of a concrete car comprising a metal center sill and bolsters, a concrete body comprisinga .fioor, longitu dinal metal members at the edges thereof,

cross members associated with said floor and connected to the longitudinal metal members, reinforcement connected to the ;two sets of metal members, concreteembedding said reinforcement and contained between the longitudinal members, concrete sides and ends connected with said floor, said sides and ends comprising longitudinal metal members, reinforcement connected thereto and to longitudinal metal members of the floor and concrete embedding said reinforcement and contained within the limits of the longitudinal metal members, and cons necting means such asthe plates 20 for connecting the concrete body as a whole to the center sill and bolsters. From the foregoing it will be seen that applicant has a metal underframe .and a concrete body having a floor and sides and ends of concrete. The body may beseparate from the underframe, and may be con? structed separate therefrom, and then placed on the metal underframe and connected therewith. It will further be seen that there are separate metalv members or connecting pieces'2O connectedwith the bottom or floor of the body and by. means of wliich, through suitable bolts orthe like, thefbody is connected with the sills and bolsters] The cross bearers or cross members of the under frame may be attached to the longitudinal sill 30, as shown'in Figure 18, oiflmayibe separate'from the center sill 15 and attached thereto by the fastening plates 19 as shown in Figure 3. When this construction is used the cross pieces '18fmay be fastened to the center sill 15'before the body isplaced thereon, or they may be attachedto. the body by the connecting piecesf20, and then fastened to the sill'15 after the body is placed thereon. Different forms of stakes are shown, the stakes projecting on one :side only being shown in Figure '5 and .the

stakes projecting on both sidesbeing shown.

in Figure 6. p v

Figures 1 and 4 show the body without the concrete cross bearers, while Figure 19 showsv it with these cross bearers33f These concrete cross bearers will be used where desired and Omitted when it is not desired to use them.
