GEORGE KENNY, OF NASHUA, NEW HAMPSHIRE.- Letters Patent N 0. 88,720, dotted April 6, 1869.

IMPROVEMENT IN CARRIAGE-RUSS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern: Be it known that I, GEORGE KENIIY, of Nashua, in

the county of Hillsborough, and State of New Hampshire, have invented certain Improvements in Wheel,- Hubs; and do hereby declare the following to be a full, clear, andexa'ct description thereof, reference being had to the accompanying drawings, in which Figure 1 represents my improvedwheel-hub in perspective Figure 2 represents a section of wheel-hub, with spokes inserted.

The subject of my invention is an improvement on an invention for which Letters Patent were granted me by the United States, August 18, 1868, which'embody the principles of this improvement; .but I wish to add to the invention thus secured, by improvements, which will render it applicable to hubs used in constructing velocipedes, and when a double set of spokes is required in carriage-wheels.

The invention,alreadyreferred to and patented, consists of a metallic ring, provided with sockets for spokes, and screw-threads on inside, this metallic ring being screwed upon the wood part of a hub.

The nature of this invention, which forms the subject of the present application, consistsv in driving a metallic ring, or flange, supplied with a double set of v sockets, corresponding to the mortises of the hub upon the hub, thereby enabling a builder to use a much smaller hub, and, at the same time, a much stronger and more durable one, while a double set of spokes may be used, thus securing a wheel, the rim of which is braced from both sides. The advantage of this construction will be seen at once.

In the drawings- A is a metal ring, or flange, having sockets a a b 72 arranged around the periphery in alternate parallel order.

, This ring is driven on to the wood part, m, of'a hub B, and for this purpose, the bore 0 of ring A is made slightly tapering, as shown in fig. 2. Driving this ring on, in paint, holds the wood perfectly tight.

The wood part of the hub is provided with mortises, which, of course, correspond with the sockets in the ring.

When the spoke's'cl d are set in a hub constructed in this manner, they brace the wheel from both directions, as indicated in fig. 2, being as they are set apart at the hub, but coining into a straight line, marked by the'wheel-rim. This gives a strong wheel, one that will stand straight Without dishing, and what is needed in constructing wheels for velocipedes and carriages, but more'especially for velocipedes.

The tenons of the spokes are constructed to fit the mortiseof the wood part of the hub, and the shoulder above the tenon; that is, the part at E is bevelled, to fit the socket in the metal.

What I claim, therefore, as my invention, and an improvement on, my Letters Patent of August 18, 1868, No. 81,175, is

The taper-bored metallic ring A, provided with'sockets a an b 1), around theperiphery of the ring, in alternate parallel order, corresponding with the mortises in the wood part of the hub, the spokes fitting into the" sockets, and tenoned into the wood, substantially as and for the purposes herein set forth,-

In testimony whereof, 'I have signed my name to this specification, in the presence of two subscribing witnesses.

GEO. KENNY.
