MINE can.

Application filed March 31, 1923. Serial No. 629,052.

This invention relates to improvements in cars especially adapted for use in mines or other places where the height of a passage is limited and the carrying capacity of the car is an important factor.

An object of the invention is therefore, to provide a car of the type usually employed in mines, of increased strength and increased carrying capacity, and this without increasing the height of the car above the rails, which would entail making expensive alterations in the mine, such as removing the roofing and lowering the floor,or in any way increasing the height or width of the mine passage.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure l is a top plan view of a car constructed in accordance with the invention, a portion of the'body being broken away to more clearly show the frame of the car.

Figure 2 is a side elevation of the improved car.

- Figure 3 is an end View.

Figure 4 is a longitudinal sectional view on the line 44 of Figure 1.

Figure 5 isa transverse sectional view on the line 55 of Figure 2.

Referring in detail to the drawings, and especially to that form of theinvention disclosed in Figures 1 to 5 inclusive, the car is shown as comprising a frame which includes channel-shaped side rails or sills 10, which taper upwardly and outwardly at each end, where they are connected by end bars 11. These end bars are provided with inwardly extending spaced parallel arms 12, which are secured to each end of each of the side rails 10 and at the outer ends of the arms 12, the end bars 11 are provided with shoulders 13, against which the side rails 10 abut. As the parallel arms 12 extend inwardly along the side rails for an appreciable distance, they act together with the shoulders 13 to provide a strong and rigid connection between the end bars and side rails. Extending outwardly from each end of the frame is a bumper 14, while spaced above this bumper is a draw bar 15, the bumpers 14 and draw bars 15 being each provided with openings 16 for the passage of coupling pins. v

Secured along the lower edges of the frame. are inwardly extending angle irons 17, while riveted or otherwise secured to these irons is a bottom or floor 18. Secured to and extending above the frame, are the sides 19 and ends 20 of the car body, the former extending laterally beyond the Width of the frame as shown in Figures 3 and 5 of the drawings. The. sides 19 .and ends 20 of the body may be of any suitable materialand may be reinforced and strengthened by vertical and horizontal reinforcing strips 21 and 22 respectively.

Extending through bearings provided in the side rails 10 are axles 23. bearings are shown as comprising sleeves 24 The said which extend inwardly from the siderails 10 and which provide bearings for the axles 23, and outwardly extending sleeves 25 of a larger diameter than the sleeves 24 which receive the hubs 26 of supporting wheels 27 The sleeves 24 and 25 are intre'gral with the bodies 50, interposed between and braced by the upper and lower flan es of the side rails or sills 10. The axles o the wheels 27 are thus disposed above the bottom-18 of the car, so that the depth and consequently the capacity of the car body will be increased without increasing the height of the car above the rails, and at the same time the car wheels are strongly connected to the car body. L

The portions of the axles 23 which extend through the car body are enclosed beneath hoods 28, whose opposite ends are connected to the side rails as shown at 29 and whose lower edges are secured to the bottom 18 by transversely arranged angle i'rons 30. The latter not only serve as a means of securing the axle protecting hoods in place, but serve to stiffen and strengthen the bottom of. the car body.

The invention is susceptible of various other changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope ofthe appended claims.

Having described the invention what is claimed is 1. .The combination in a car, of side rails or sills of channel cross-section, a bottom interposed between and connected to the lower portions of said side rails or sills,

-bearings arranged in and brac'ed by the side rails or sills'and having inwardly and outwardly extending sleeves, the outwardly extending sleeves having comparatively large interior diameters, transverse axles extending through the said sleeves of the bearings and also through the side rails or sills, and wheels mounted on the axles outwardly beyond said bodies and having inner bodies arranged in and braced by the side rails or sills and having inwardly and outwardly extending sleeves, the outwardly extending sleeves having comparatively large interior diameters, transverse axles extending through the said sleeves of the bearings and also through the side/rails or sills, and wheels mounted on the axles outwardly beyond said bearings and having inner portions disposed in the outer sleeves of the bearings, with transverse hoods arranged over the intermediate portions of the axles and also over the inwardly extending sleeves of said bodies and interposed between and connected to the side rails or sills and 'also connected to the said bottom.

3. The combination in a car, of side rails or sills of channeled cross section having their outer ends inclining outwardly and upwardly, a body interposed between and connected to the lower portions of the side rails or sills, bearings arranged in and braced by the side rails or sills and having inwardly and outwardly extending sleeves, the outwardly extending sleeves having comparatively large interior diameters, transverse axles extending through the said sleeves of the bearings and also through the side rails or sills, and means mounted upon the axles outwardly beyond said bodies and having inner portions disposed in the outer sleeves of the bodies.
