UNITED STATES JORAM PREIST, OF DETROIT, MICHIGAN.

IMPROVEMENT IN WAGON-WHEELS.

Specification forming part of Letters Patent No. 118,815 l dated September 12, 1871.

To all 'whom it may concern:

Be it known that I, J CRAM PREIsT, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in WagOn-VVheels and I do declare that thefollowing is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l is a perspective of my wheel without the fellies and with the spokes broken oi. Fig. 2 is a perspective ofthe metallic section forming the outer end of the hub. Fig. 3 is a similar view ofthe section forming the inner end of the hub. Fig. 4 is a plan, with the section shown in Fig. 2 removed. Fig. 5 is a perspective of the Wooden filling, with metallic sections removed. Fig. 6 is a perspective section ofthe spoke.

Like letters refer to like parts in each figure.

The nature of this invention relates to an improvement in the construction ofwagon-wheels, whereby a stronger, lighter, and more durable wheel is obtained than those now in use. The invention consists in the combination ofthe various parts When each is constructed substantially as set forth, and as more fully hereinafter described.

In the accompanying drawing, A represents the outer section, cast in any suitable metal, the extension a of the same forming the band usually placed on the outer end of a Wooden hub. This section is also provided with a ange, b, concave upon its inner side, as shown, and through this flange are bolt-holes c, for the purposes hereinafter described. B is the inner section, cast as above described, provided with a corresponding flange, d, extension h, and bolt-holes e, while from the inner face of the flange, and cast therewith, is a series of studs, f, which, in their length, are about equal to the width of the inner end of the spokes. The bolt-holes e are continued through these studs. C is the wooden filling, into which may be inserted the usual boxes in which the axles run. Around this filling there is turned out the groove g, the width of the groove being the same as that of the inner end of the spokes.

In the construction of this wheel the section B is driven onto the inner end of the wooden filling until the inner edge of the flange is coincident with the rear edge of the shoulder or" the groove. The spokes D,.the ends of which are provided with a double dovetail-shaped tenon, as shown, are then inserted between the studs f until their ends rest in the bottom ofthe groove in the wooden iilling, the spaces between said studs, in combination with the groove, performing the same functions of the lnortise in the usual way of inserting spokes. The section A is then driven onto the opposite end ofthe wooden filling until the flange strikes the spokes, when bolts or rivets are inserted through the holes c e to hold the whole rmly together; the concave surfaces of the lianges fitting the dovetail-shaped tenons of the spokes and preventing them becoming loose or from being withdrawn.

I am aware of the wheel patented by .I ames D. Sarvere on the 9th day of June, 1857, and utterly disclaim any part thereof; but

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the sections A and B, each cast in one piece, and provided with concave iianges b and d, the section B also provided with studsf, the wooden hub C provided with groove g, and the spokes D, the several parts being constructed, arranged, and secured together, substantially as described and shown.

J ORAM PREIST.
