The hub c'is bolted on the to abut the ends of the thimble z. axle through the flanges c. In order to more clearly explain the utility,

I shall now describe the adjustment and operation. The inner sides of the split hub are carefully faced off after being bolted on the axle, so that the gear 71 may fit closely thereto, and the outer circumferential surface of the split hub is turned true, so that it may be concentric with tread of axle-wheels. The gear-wheel his bolted securely to the split .hub o, the latter forming the bearing for the said gear in its revolutions with the axle. The inner periphery of the sleevej is not designed to bear on the axle at any part of its surface. The rotation of the gear h with the axle a turns the gear .9, which is journaled in the arm g from the strap 1).

It will be seen in the following explanations that the revolving of the sleeve will in no wise affect the position of the gear 3. The positions of the sleeve j and the axle a must always be identical-that is, any vibration or sudden jar affects bothfor the sleeve extends from the gear h, and this gear through the separable hub bears on the axle and turns therewith.

The adjustable and swinging support allows the truck and axle to have considerable lateral movement, which is extremely essential, as such lateral motion is constant and is especially emphasized in rounding curves.

It will thus be seen that the rigidity of the arm q is much relieved.

The main object of this invention is to provide for the exact meshing of the teeth of the gear-wheels, not withstanding the changes of positions of the axle and the truck while in travel. This is to a large extent accomplished by the adjustable support of the arm q through the turning of the rod y in the rings 00 and the consequent raising and lowering of the rod y. The springs 2 allow a limited lengthwise movement of the rod in the thimble z to account for the different vertical positions of the axle and the truck in relation to one another. It will be thus seen that at each circumferential movement of the sleeve the gear assumes a position relatively the same radial distance from the center of the axle. The gears are always in engagement one with the other, yet they are free to move with the changes in position of the truck or axle and still be in constant engagement.

The adjustment for the centering of the gear h in order that it may be concentric with the tread of axle-wheels is a very important feature in this device, and the means for accomplishing this are simple and effective and can be readily understood by any ordinary mechanic.

As before explained, the parts of the gear are bolted to the projecting flanges of the split hub through the slots f. This will allow the said bolts a considerable movement radially from the center of the axle. The movement of these bolts is controlled by the set-screws i, inserted through the bosses g,and as there is an intervening space between the that the wheel is concentric with the tread of axle-wheels.

The difficulty hitherto experienced in centering of wheels is well known, and consequently the ease and facility with which by the simple turning of the set screws the wheelmay be centered will be much appreciated by mechanics and those otherwise interested. For instance, in this device a positive accuracy can be attained in a very short time by adjusting one screw after the other until they are, as before explained, equidistant from the circumference.

When the gear h is concentric with the axle, the strapp is bolted in a circumferential groove on the sleeve j, and, as explained heretofore, the gears is always at the same radial distance from the center of the axle, and therefore from the center of the sleeve and strap, for with the gear it they are concentric with the axle. Consequently the gear 8 may be engaged by the gear h equally well in the varying positions of the arm (1 caused by the jolting of the truck or the axle.

The shaft 15, which is rotated by the gear 3, extends into a dynamo or other machine requiring the power transmitted by the revolutions of the axle, and in extending this shaft it is probable that a universal or other suitable joint will be required intermediate of the distance between the dynamo and the gear. However, I have not shown this in my drawings, as it is well known and needs no further explanation.

In Fig. at I have shown a plan view of an alternative form of gearing, in which the arm from the strap is further extended, so as to form a bearing for the gear heretofore indicated, as s, in order that the said gear may engage the spur-gear instead of the bevelgear h illustrated in the other drawings. The form of the swinging support and the general arrangement may be precisely the same as in that already described, and it must be here understood that I do not confine myself to any particular form of gearing, as many may be adopted using substantially the same arrangement.

The use of gearing for transmitting power from revolving axles in transit appears to be the only positive manner of transmitting power from the said axle, as there is no slipping, as in belts, and very little wear, and all the mechanism connected therewith may be suitably incased, so as to preserve it from the inclemency of the Weather, though this will of a hub having projecting flanges therefrom,
