GEORGE HUNT, OF PRATTSVILLE, NEW YORK.

` MODE 0F ATTACHING CARRIAGE-WHEEL HUBS T0 THE ARMS OIE' AXLETREES.

T0 all whom t may concern Be it known that I, GEORGE HUNT, of Prattsville, in the county of Greene and State of New York, have invented a new and Improved Form of Constructing Metallic Hubs Adapted to the Use of Coaches, Carriages, and Wagons of Every Description; and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in confining the hub to the axletree by means of a band fastened to the flanch on the axletree and embracing the anch on the pipebox instead of confining by means of linch pins, nuts or springs, &c., as heretofore used, and in confining the oil or grease in the box and excluding the dust, mud or gravel from entering and increasing the friction. The object of the open spaces is to make the rim of the hub .for light wagons and carriages large enough to receive the tenons of the spokes the full size of the spoke and that in heavy Wagons the ends of the spokes may go far enough through the rim to be keyed on the inside.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction as follows:

Figure l represents an iron axletree after the usual form; A, the post to which the pipe-box is fitted and on which it turns; B, the shoulder represented by Fig. 9 in the annexed. drawing; C, the hole through which the bolt B, Fig. 3, passes, fastening the cap or band to the shoulder.

Fig. 2 represents the pipe-box; A, the shoulder running against the shoulder B, Fig. l; B, a small nut or projection entering the slit A in the hub, Fig. Ll, to prevent the hub from turning on the pipe-box.

Fig. 3 represents the cap or band which receives the fianch of the pipe-box and the bolts to the axletree; A, the rim resting against shoulder A, Fig. 2, and confining the pipe-boxto its place on the axletree; B, the bolt which fastens the cap to the axletree by passing through the cap and through the axletree at C, Fig. 1, and fastened by the nut screwed on at C, Fig. 3.

Fig. l gives a. view of the hub; A, the slit fitting on the nut B, Fig. 2; B, a screw opposite the slit A passing through the hub and pipe-box to confine them more securely together. This screw can be withdrawn at any time and oil poured through the hole into the pipe-box, thus obviating the necessity of taking off the Wheel for the purpose of oiling or greasing; C, O, C, mortises for receiving the spokes.

Fig. 5 represents the parts connected t0- gether the interior parts shown by dotted lines; A A, the axletree; B B, the pipe-box; C, the cap or band; D, the head of the bolt. fastening the cap to the axletree; E, the nut holding the bolt; F, slit and nut holding the hub to the pipe-box and causing the box to turn with the hub; G, the screw for the same purpose; Fig. G, the above mentioned screw-enlarged. This screw may have a square head, so as to be turned by a wrench, or a hole through the head to be turned by a pin or bolt, or both if desired.

Fig. 7 represents a cotril or washer to go between the shoulders of the pipe-box and axletree and between the rim of the cap and shoulder of the pipe-box to prevent the wearing of those parts.

Fig. S is a side view of the hub, showing the manner in which the arms and rim are formed.

Fig. 9 represents the shoulder B, Fig. l. This shoulder may be made of cast iron with a square eye, as Fig. 9, to slip on the square part of the wrought iron axletree, and the bolt B, Fig. 3, passing through it and the axletree holds them together.

Fig. 10 is a longitudinal section enlarged showing the several parts connected; A A, the axletree: B B, a section of the pipe-box divided longitudinally; C, C, a section of the cap which confines the pipe-box to the axle-tree; D, D, the bolt which contines the cap to the axletree. The passage of the bolt through the axletree is shown by the dotted lines; E, E, the hub; f, the nut on the pipebox entering a slit in the hub. causingT the hub and pipe-box to revolve together; G, a screw passing through the hub and pipebox for the same purpose, as also by withdrawing the screw to have an opening to introduce oil or grease to the axle.

That I claim as my invention is- The mode of securing the pipe-box of the hub on the arm of the axletree by means of the band attached to the lanch of the axletree and embracing the tlanch on the pipebox, as herein described.

GEORGE HUNT.
