J., assignor to American Car and Foundry Company, New York, N. Y., a corporation of New Jersey Application January 27, 1933.' Serial No. 653,850 12 claims. (o1. 10a-364) This invention relates to mine cars and has for one object the provision of a n ew and improved mine car of large lading capacity in which the body is supported by stub axles. x

Another object of this invention is the provision of a mine car having a new and improved combined stub axle and wheel hood assembly.

Other objects and advantages of this invention will be apparent from the following description taken in conjunction'- with the accompanying drawings in which:

Figure 1 is a side elevation the present invention.

Fig. 2 is a sectional view on the line 2-2, Fig. 1. Fig. 3 is a sectional view on the line 3-3, Fig. 1. Fig. 4 is a sectional view on the line 4--4, Fig. 3. Fig. 5 is a sectional view on the line 5-5, Fig. 3. Fig. 6 is a sectional view through the side floor portion of a car showing a modied form vof the 2 0 invention.

of the mine car of Fig. 7 is a side elevation view of the construction shown in Fig. 6, and

Fig. 8 isa top plan view of the construction shown in Figs. 6 and 7.

Referring now more particularly to the drawings in which similar characters of reference designate similar parts in the several views, the mine car of the present invention comprises abody indicated generally at A having side walls 2, a fixed end wall 4, and an end gate 6, the latter being provided with a bail 7. While the drawings show an end dump mine car, it will be apparent' from the description that within the spirit of the invention both ends of the car body may be provided with fixed endy walls to provide a rotary dump car if desired.

'Ihe body includes a bottom indicated generally at B and comprises a central floor portion 8 se.- cured to or formed integral with the body side sills. In the instance shown, the side sills are indicated generally at S and comprise upwardly and then outwardly extending

flanges

10 and 12 respectively of the side edge portions of thecentral floor 8. If desired, independent members such as rolled Z-sections, channels, angles or the like, or suitable plate metal members may be utilized to form the side sills.

The car body also includes two main oppositely arranged side sectionsI but inasmuch as they are 00 identical only one thereof is shown. The side section is shown clearly in Fig. 3 and is shaped by a bending operation to provide a side door portion 14 and the side wall 2 integral with said portion 14, the section being secured as byrivets 16 f to the upper flange 12 of the side sill and being provided withwheel receiving openings 18. The

upper edge portions of the side and end walls are stiiened in any suitable manner as by an inturned bead 20 and the entire body is reinforced by belts 22 secured to the sidewalls -and extending under the body from side to side; the belts tral iioor portion and lying against the side sills. The belts 22are secured to the car body by suitable fasteners such as the rivets 24. y

The Wheels are indicated at 26 and they carry stub axles 28 mounted in oppositely arranged outer and inner bearing

members

30 and 32 respectively, bearing 30 comprising a. socket 34 formed with a bracket 36 secured to a support 38 depending from the side floor portion 14 (see Fig. 3). Bearing member 32 comprises a pedestal 40 formed integral with a bracket `42 having oppo- 'sitely directed arms 44 which are of a length sufcient to extend between adjacent straps 22.A A pin 46 extends between the pedestal jaws for an obvious purpose, as clearly shown in Figs. 2 and 5.

To close thev openings 18 and to cover the wheels 26, wheel housings indicated generally at H are provided, each of which comprises a metal l extending from the side floor portions and cen.

pressing formed to. provide a hood portion 48 having a marginal attaching flange 50 extending completely therearound and of such a dimension as to underlie-the side floor' portion completely aroundthe opening 18 (see Fig. 2), and to extend between and to underlie adjacentv belts .22, as

shown in Figs. 4 and 5. In practice the end portions of the marginal flange 50 are interposed between the belts 22 and the arms 44 of the bearing member 32 and the rivets which connect the arms 44 to the car body also serve to secure the wheel housings H. l I r The iiange 50 at its sides is formed with depending attaching iianges or extensions 54 and 56 arranged respectively between bearing member 30 and support 38 and between bearing member 32 are then inserted through the wheely openings 18.

The

bearings

30 and 32 are then applied in position and secured, together with the wheel'hood, to their respective supportsthe support 38 and the Side. .S..1 1 E. `This being done, the; stub axle with its associated wheel 26 may then be easily inserted into the

bearings

30 and 32 and secured against displacement by the pin 46. The construction herein provides a strong and durable mine car which is formed of few parts and is easy and inexpensive to manufacture. It is apparent that the wheels 26 may be easily and quicki-v ly removed from their supporting

bearings

30 and 32 for replacement or repair.

Figs. 6, f7 and 8 show a modied form of the invention and more particularly disclose a form of car at the wheel housing portion. The wheels 26 carry stub axles 28 which are mounted in inner and outer pedestal members. To distinguish the construction in Figs. 6, 7 and 8 from the remaining figures in the drawings the pedestal members are indicated at 60 and 62 respectively andare substantially identical, each having legs 64 which dene therebetween a jaw 66 which receives the axle 28. Tie bars 68 are provided for an obvious purpose.

The wheel housing in Figs. 6, 7 and 8 is indicated at '70 and is substantially rectangular in plan, being provided with a marginal attaching flange 72 which, along one side portion of the housing, extends under the side sill S and is provided with a depending attaching flange 74 interposed between the inner pedestal members 60 and the side sill. Suitable fasteners 76 secure the pedestal 60, side sill S and ange '74 together as clearly shown in Fig. 6.' The opposite portion of iiange 72 underlies the side floor portion B of the car bottom (shown in broken lines in Fig. 6) and rests upon the horizontal portion 78 ofan internal wheel housing brace member indicated generally at 80 provided with a vertically arranged web portion .82 which extends to the upper portion of the wheel housing and has its upper edge portion welded to said housing as shown at 84. The side edge portions of the web.82 are flanged outwardly as shown at 86 and are united with the upwardly sloping outer wall 88 of the wheel housing 70 by being welded thereto as shown at 89. The horizontal leg 78 of the brace member 80 is supported on the downwardly oiset portion 90 of a channel-shaped side floor portion supporting member 92. The portion 90 of the channel member 92 is downwardly offset a distance sufficient to permit the marginal flange 72 of the wheel housing '70 to be in substantially the same horizontal plane as the web of the channel member 92, as shown clearly in Fig. 6, the channel member 92 being attached to the side floor portion B and the latter overlapping the marginal iange 72 as shown in brokenlines in Fig. 6. If desired, the rivets 76 may be eliminated and connection of the pedestal 60, ilange 74 and sill S be made by welding. It

` is also apparent that while other rivets or fasteners may be used to connect the side oor portion B and channel member 92, these elements may be connected, if desired, by welding. The member 92 serves as a support for the outer pedestal member 62 and the latter may be secured in position in any suitable manner as by being Welded to said member 92. In the construction shown in Figs. 6, 7 and 8 it is apparent that the several parts may be connected together by welding and that the wheel housing 70 is braced by the member 80. It will also be apparent that theside oor portions B are stiiened and reinforced by the member 92 and the connection between the wheel housing 70, brace member 80, and channel member 92 is such as to stiften the car at this particular zone. Due to the fact that the

members

60 and 62 are pedestal members i't will be apparent that upon removal of the tie bars 68 the body may be lifted to remove the wheel 26 and axle 28 as an` assembled the present invention will be fully apparent to i those skilled in the art but it is to be understoodthat the drawings herein are for illustrative pur.

poses only and various changes in the form and proportions of the construction may be made within the scope of the appended claims without departing from the spirit of the invention.
