Sept. 17, 1935. H. P. FIELD MINE CAR v Filed Oct. 20, 1951 s Sheets-Sheet 1 rrammr Patented Sept. 17 1935- UNITED STA S PATENT OFFICE- VMINE can Henry P. Field, Berwick, Pa assignor to American Car and Foundry Company,- New Yor N. Y., a corporation of New Jersey Application October 20, 1931, Serial No. 569,937 25 Claims. (01.105-364) may be quickly and conveniently assembled 'cornplete with axles and wheels. A further object is to provide'a particularly durable car offering a high resistanceto the severe 15 strains associated with the operation of mine cars. Other objects will appear from the following v description of the construction and operation of I this improved mine car.

The invention accordingly consists in-the vari- 20 ous features of construction, combinationsof elements-and arrangements of parts which are exemplified by the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims. 25 Referring now to the drawings, wherein is shown one of various possible embodiments of the v invention Figs. 1 and 2 conjointly represent amine car in longitudinal section; in Fig. l the section is 30 taken along the median line and in Fig. 2 along the line 2-2 of Fig. 3;

Fig. 3 is a top plan view of the construction shown in Fig. 2; Fig. 4 is a view in cross-section taken on the line 35 4-4 of Fig. 3; and

Preferably these are rolled .metal bulb-angles .comprising webs l2 developing at their upper extremities into beads or heads l3. As these bulbangles are arranged in the'present construction 45 lower horizontal flanges l4 extend inwardly to-' ward the center line of the body. v Secured to the flanges l4 asby riveting or welding are bail-shaped members I5 having horizontal flanges l6, supported on the sill'flanges 50 14; upright portions l1 and horizontal flooring portions [8. Preferably three of these members l5 are employed as shown in Figs. 1 and 2 of the drawings, there being one section between the car axles and one between each car axle and its cor.-

155 responding end. These members constitute what termed herein the central flooring which is completed by axle hoods or shrouds I 9 riveted to the horizontal flooring portions l8 and also to p the uprights ll, of the floor. members l5.

To the outer faces of the web l2 of the sills 5 l0 and II the upright flange of sheet metal side floor sheet members 20 are attached as by rivets I 2|. The uprightflange of these members depends from the sills tothe angle point 22 where a hori- 'zontal floor 23 extends outwardly thereby pro- 10 viding what are termed hereinside floor portions.

. In the present form of the invention there are three of the floor sheet members 2|] on each side of the car, these being spaced apart at their ends to accommodate the car wheels.

Spaced outwardly from the supporting sills l0 and II are sheet metal side walls 24. These walls extend substantially higher than the plane of the top of the sills and have rolled-over edges 25' for strengthening purposes. The side walls also extend lower than the plane'of the bottom of the sills, their lowermost extremities 26 having turned-in flanges 21 which are overlapped by the horizontal web portion or side flooring 23 and secured in overlapped relation. 25 End walls 230i similar construction-to the side walls and located in'substantially'the same hori- I zontal plane are joined to the side walls by suitable angle irons at the corners. The end walls 28 are also joined to the sills l0 and H by angle 30 irons 3| and are joined to.the central flooring by angle members 32.

To further increase the sturdiness of the car the upright flanges H of the central flooring members ii are connected to the upright webs of the side flooring members 20 by Z-shaped members 33. These members definitely space the upright webs of the central and side floorings and resist lading and operating strains.

Each of the axle hoods l9 consists of a bailshaped member 34 having a top horizontal web 35 with end extensions 36 which overlap the inwardly extending flanges ll of the sills and .are preferably welded thereto. Downwardly extending webs 31 of the axle hoods have outwardly turned flanges 38 which overlap the ends of the horizontal central floor sections 18 and are secured thereto as by rivets 40 thereby connecting said floor sections. These axle hoods also have outwardly turned flanges 4| extending vertically and attached to the upright webs l'l of the central floor portions I5. The construction de- -seribed provides a complete and continuous central floor portion supported primarily by the lonaccommodation of axles as will appear presently more in detail.

Wheel hoods 50, preferably of sheet metal, are arranged between each of the sill members it! and II and its corresponding side wall 24. Each of the hoods has a substantially curved body portion 5| with corresponding outwardly turned flange 52 and inwardly turned flange 53. The flange 52 abuts the side wall of the car and is riveted thereto. Flange 53 abuts a filler 53 which is interposed between said flange and the sill 10 or H, as the case may be, and is secured to the filler and to the sill by the rivets 2!. The wheel hoods 50 also have out-turned flanges 5 6 at the bottom which overlap the horizontal floor portions 23 at their ends adjacent the axle and are riveted in overlapping relation. This construction employs the wheel hoods as substantial means to assist in carrying the side walls and side floor sheets and presents continuous side flooring from end to end of the car, there being, however, indentations from the bottom upward to accommodate the wheels at the ends of the axles.

The structure as thus far described is composed of sheet metal and commercially rolled shapes and forms a mine car so constructed and reinforced as to be capable of resisting all of the ordinary strains of lading and operation. In completing the assembly cast axle seats or pedestals 55 are secured to the sills l0 and H, respectively, the attachment being preferably to the bottom face of the inwardly extending flanges i l of the sills by means of rivets 56. These pedestals are in the transverse plane of the axle hoods i9 and have flanges 5T registering opposite the outwardly turned flanges of the axle hoods and joined thereto by rivets 58 which pass through the flanges of the pedestals, the flanges ll of centrm floor portions l5 and the overlapping flanges of the axle hoods l9 whereby the load is transmitted to the pedestals and thence to the axles of the car.

The axle receiving means or pedestals are preferably characterized by an inverted U-shaped,

opening 60 whereby an axle 6| may be introduced to and associated with the car body by a straight transverse relative movement as distinguished from an axial or longitudinal insertion of the axle. When the axles are so associated they are located in position in seats 62 of the pedestals and held against dislocation by pins 53 passed through the lower portion of the pedestals and removably secured therein by cotter pins 64. Each of the axles is equipped at either end with wheels 65 which may be mounted with antifriction bearings 66 or in any other suitable way to rotate on the axles.

It is to be noted that the pedestals are arranged preferably below the longitudinal sills and no weakness of the sills is effected in the present construction by reason of the cutting of slots or apertures for the reception of the axles. When the body and wheeled axles are assembled the plane of the axle is below the sills yet substantially higher than the central and side flooring. This, without weakening the body frame construction, lowers the center of gravity of the load with respect to the track upon which the car runs. It also provides a car of high lading capacity yet with side walls lowered so that the tops thereof are easily accessible from the ground. The'body is given highly increased sturdiness by reason of the curved wheel hoods and the angular axle hoods and the means of locating and attaching same with respect to the sills, the flooring and the side walls. Also the Z angle ties 33 serve with the axle hoods and wheel hoods to strengthen the body to resist the lading and operating strains without materially increasing the weight The car is further provided with end bumpers l0 and ll. These are substantially alike except for minor details of construction and only one will be described. The end wall 28 is terminated at 1'2 slightly above the flooring portions i5 and 23 allowing for the introduction of a lower horizontal flange 13 of a Z-shaped end sill l4 having an upright web 15 and an upper horizontally extending flange 16. This flange is centrally reinforced by a plate 71 and this reinforced portion is apertured to receive a coupling pin 18. A wood bumper filler 19 has its rear face abutting the front face of the vertical web 15. The bumper has upper and lower metal clamping plates and 8!, respectively, the upper plate having an upturned flange 82 which abuts the web 15 of the end sill and is connected thereto by rivets which pass through the flange 82, web '15 and the end wall 28. The lower plate 8| has an extended flange 82' which laps the flooring and is secured thereto and to the flange 13 at 83. The assembly of bumper filler I9 and upper and lower plates is embraced for a portion of its width by a channel-shaped end member 84 which is secured in position by bolts 85 passing through the horizontal extensions of the member 84 and through the clamping plates and the bumper filler. This assembly is also recessed at 85 to receive the coupling pin 18.

Obviously this bumper construction has an effect toward increasing the rigidity and sturdiness of the car but it will be seen that the bumper construction does not necessarily enter into the invention in many of its broader aspects as the car is complete and rigidly self-sustaining in assembly with its axles irrespective of the bumper construction just previously described.

Commercial embodiments of a preferred form of the invention present the plane of the wall-tops approximately two feet from the track rails and the plane of the side floorings less than four inches from the track rails. It is obvious that in case of need the axles with their supporting wheels can be removed by jacking up the car body and removing the pins 63. The removal may be effected without disturbing the roller bearing adjustment and assembly of wheels and axles. In original construction the axles are dropped into the pedestals 55 of the car when the latter is in bottom up position.
