IMPROVEMENT IN HUBS FOR VEHICLE-WHEELS.

Specication forming part of Letters Patent No. 149,625, dated April 14, 187,4; application filed December 29, 1873.

To all 'whom t may concern.-

Beit known that I, JOHNSTON V. WOOLSEY, of Sandusky, in the county of Erie and State of Ohio, have invented a certain new and Improved Carriage -Wheel Hub, of which the following is a complete description, reference the prevention of the ends of the mortises from giving way or crowding up by the pressure of the tenon of the spoke while it is being driven therein. i For this purpose is used a band, of a peculiar shape, at each end of the mortise', which not only avoids the trouble above said, but which also prevents the hub from'splitting or cracking.

Of the above invention the following is a more complete description In the drawings, A represents the hub, which is or may be of the ordinary Wooden kind, having a middle projection, d. B C are bands surrounding the hub at each end of the mortise-space. It will be seen, on examination of Fig. 2, that the under inner edge of each band is beveled back under the band, as shown at a, and that the' outer edge of the bands is curved downward, and pressing into the wood, there being a groove made in the hub to receive the edge of the band as it is bent or pressed into it to a little depth, forming a shoulder for the curved edgel of the band to rest against, and thereby prevent it from coming on' or loose. l

. In driving the tenons of the spokes into their inortises, the mortises at the surface are very liable to crowd out, in consequence of the strain of the tenon against the ends. This crowding or forcing out of the wood weakens the ends of the mortises, so that there is less support for the tenon'than if such forcing out of the wood had not been 3 to avoid'which is the purpose of the bands referred to, which are pressed upon the hub at each end of the Inortise ush with the surface. The outer edge then rolled down and pressed into the wood, thereby forming a smooth rounded shoulder, D, while the edge c pressed into the wood prevents the band from coming oi' or loose.

On driving the spoke into the mortise, the ends of the mortise, instead of being crowded or pushed'out, will be .crowded down under the band, in consequence of the slant or bevel a on the under side, thereby compressing or packing the wood under the band, and thus making irm and solid ends to the mortises, for the'support of the tenons of the spokes.

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

'lhe bands O B, with a curved edge, c, and a beveled edge, a, in combination with the hub A, having middle projection d, the beveled edge a pressing against the projection, and the curved edge c pressed into the wood, substantially as described, and for the purpose set forth.
