UNITED s'rrss HUGH W. SANFORD, OF KNOXVILLE, TENNESSEE.
MINE CAR.
Application filed March 10, 1924. Serial No. 698,221.
To all whom it may concern:
Be it known that I, HUGH W. SANFORD, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Mine Cars, of which the following is a specification, reference being had to the accompanying drawing.
My improvement relates particularly to the wheel and axle and axle bearing construction of mine cars. Y
The object of the invention is to provide a convenient and effective construction wherein there is provision for conveniently making the wheels tight or loose? on the axle, the axle being in bearings which permit its rotation. In cars of this general type, it is the practice to operate the cars with the wheels tight on the axles at one side of the car and loose on the axles at the other side of the car.
In the present improvement, one end of the wheel hub is made of angular interior cross section, and an engaging member is placed within said part of the hub and put into engagement with the hub and with the axle for compelling rotation ofthe axle with the wheel.
In the accompanying drawings,
Fig. 1 is an upright section showing a wheel and axle and axle bearing, my improvement being applied to the wheel and the axle;
Fig. 2 is an elevation looking at the axle and the hub from the left as I shown in Fig. 1;
Fig. 3 is an upright,- transverse section on the line, 3-3, of Fig. 1, looking toward the right;
Fig. 4 is a perspective of the engaging member which intervenes the axle and the outer end of the hub;
Fig. 5 shows the outer end of the axle and the hub of Fig. 1, with the engaging member removed and an ordinary washer substituted, whereby the wheel is made loose on the axle;
Fig. 6 is an upright, transverse section on the line, 6-6, of Fig. 5, looking toward the right;
Fig. 7 illustrates the outer end of the axle and the engaging member and the outer end of the hub with the cotter pin placed close to the hub;
Fig. 8 shows a thick washer substituted for the engaging member of Fig.7;
Fig. 9 is a view similar to Fig. 1, the axle the line, 11-11, of Fig. 9, looking toward the left;
Fig. 12 is a perspective ofthe engaging member shown in Fig. 9;
Fig. 13 shows the wheel hub and axleas shown in Fig. 9, excepting that the. engaging member has been omitted and a ring-form washer substituted, whereby the wheel is made loose on the axle; I
Fig. 14 is an upright, transverse section on the line, 1414, of Fig. 13, looking toward the left;
Fig. 15 is a transverse section on the line, 1414, of Fig. 13, looking toward the right,
'a square washer being substituted for the washer of Figs. 13 and 14.
Referring first to Figs. 1, 2, 3, 4, 5 and 6 of the drawings, A is an axle, only the part extending through one axle bearing and the adjacent wheel being shown, the wheel being at the outer end of the axle and the bearing being between the wheel and the companion bearing. In other words, in thisform the wheels are at the outer ends of the axles and the axle bearings are between the wheels. 13 is the wheel. This has a hub, B C is the axle bearing of a form hertofore used. Within the bearing are anti-friction rollers, G The upper face of the bearing is highest midway between its ends. The pedestal, C rests on the raised part of said face and is suitably secured to the floor, D, of the car body. Thus said bearing is made of the self-aligning type heretofore in use.
The outer end of the hub, B is formed into a flange, B and the interior faces of said flange are four in number and enclose a space which is square and larger than the diameter of the axle. l
The engaging member, E, shown in perspective in Fig. 4, has an upright wall, E which is square. On each of two'opposite edges of said wall is a wing, E In the bearing being outside the wheel, and the en-. gagement between the wheel and the axle' gaging member.
body, E is an aperture, E large enough to permit the passing of the axle. The wings, E are so spaced astohe against or nearly against the axle, and the body, E is of such size as to approximately fill the space within the flange, B ',whereby the ena in member is com elled to rotate with 5 b t:
and so engages the axle as to compel rotation of the hub an d the axle with the en- The result is a tight wheel. hen the wheel is rotated by movement of the car on a track, the axle is forced to rotate in its bearing in unison with the wheel.
When thiswheel' is to be loose, the c0,t.
te r pin, E is removed. Then the engaging member, E, is removed. Then an ordinary washer, W,'larger than the interior of the end of the hub,'is placed around the axle and against the flange, B (see Figs. 5 and 6). Then the cotter pin is replaced.
InFig. 1, hub thrust toward the cotter pin is taken by the right hand face of the engaging membenE'; While in Fig. 6,'such thrusts is taken by the right hand face of the washer, W. I
The distance between thev cotter pin, E
and the flange, B is made to equal the thickness of the washer, W. In other words,
the washer is made as thick as the distance between the cotter pin and the flange of the hub. In. Fig. 1, a vacant space is left between the cotter pin and the hub flange. This space is needed for the insertion of the washer, TV, when the engaging member, E, has been removed. i e
But the washer maybe made wide enough and thick enough to lie in the space enclosed by the flange, B I Then the apertures, A and E may be moved toward the hub to bring the cotter pin close to the flangaB when either the engaging member, E, or the Washer, WV, is in working position. (See Figs. 7 and 8).
Referring now to Figs. 9, 10, '11, 12, 13 andLt. A is again the axle and B is the wheel and C is the axle bearing. But, in this case the axle bearing is at the outer end of the axle and the wheel is between that bearing and the opposite end of the axle.
In other words, in'this form, the axle bearings are at the ends of the axles and the wheels surround the axles between the bearings.
In this case, theflange, B is on the inner end of the hub, B instead of the outer end, as shown in Fig 1. -The engaging member, E, is like the engaging member E, of
Fig. 1, excepting that the wings, E of Figs. 9 and 12, are shown shorter than in Fig. 1.
Furthermore, the wing apertures, E are omitted because the cotter pin is not used.
The part of the axle, A, between the wings,
directed toward the hub, are formed. Said shoulders form an abutment against which "the adjacent face of the body, E of the engaging member rests Thus the engag ing member is adapted to take wheel thrust di rected toward the opposite or jfarther'end of the axle. As in the preceding figures, the engaging member, E, makes such engagement with the interior faces of the flange,
B as to compel rotation of the engaging 'member and'the hub 1n unison. At the same time,the engagement made between the inner face of the Wings, E and the axle faces, A?, is such as to compel rotation of the engaging member and the axle in unison. Thus the engaging jmember is a member intermediate the hub and thea'xle and engages both so as to compel rotation of the hub and the engaging'member of'th'e axle in unison.
When this wheel is to bevm'ade loose,
the wheel and the engaging member, E, are removed, and a w'asher, l/V, is substituted on the axle for the engaging member. Then the wheeliis replaced. The washed is to fit the axle so closely as to cause ample-engagement between the washer and the four shoulders, A whereby said shoulders form an abutment for said Washer and adapt the washer to take hub thrust in the direction of the farther end of the axle. This washer has a circular exterior and is free to rotate in the hub or the hub is free to rotate around the washer. At the same time, the washer is free to rotate on the cylindrical part of the axle. But the outer edge of the washer may on the axle, but would be compelled to P0 tat'e with the hub.

In acar of the kind described, the combination of an axle, an axle bearing, a wheel hub of circular interior cross section and' having one end chambered and of non-circular interior cross section larger than the cross-section of the axle, and an engaging member surrounding the axle and fitted into .the chambered part of the hub to compel rotation of said engaging member with the hub and said engaging member being in operative relation with the axle tocompel rotation of the axle with said member, whereby said hub and said engaging mem ber and said axle are made to rotate in unison, substantially as described.
