IMPROVEMENT IN CARRIAGE-HUB.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, MARTIN WHELAN, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Carriage-Hubs; andI do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full,

clear, and exact description of the same, and which said drawings" constitute part of this specification, and

represent, in-

Figure 1, a perspective view of the hub, Figure 2 a transverse section of one part of 'the band removed, and, in Figures 3 and 4, the two partsof the band.

This invention relates to an improvement in the manner of securing spokes in carriage-wheels, the object being to sustain the spokes at the'hub independent of the hub proper. This object .has been partially attained by inserting thespokes into the hub, and constructing them so that the insides of the spokes meet each other a short distance between the spokes, and then by placing ahead of metal around the face of the spokes on each side and bolting therethrough. Another method .has been by placing a band around thehub, -having mortises formed therein to receive the tenon of the-spokes, and a shoulder on the spoke resting upon iron.

To the first there is this objection, that-there is so largea bodyof wood entirely around the hub that a very slight shrinkage mustiopen some of the joints, and; thus detract from the advantage of the union of the spokes at the hub.

v In the last construction there is this objection, that the spoke resting, as it does, upon ametallic shoulder, the slightest shrinkage tends to loosen the spoke, and when loosened in the slightest degree, the shoulder quickly wears so as to loosen the spoke. I I g By my invention these difliculties are entirely overcome, and consists in. the construction of a band. to

encircle the hub, and inserting the spokes into the wood hub so as to leave a space between each two of the spokes; v

and upon the said band I form metallic bars, which pass through the several spaces between the spokes and a eorrcsp'ondingplate driven on to the hub upon th e'opposite side, and secured to the projecting arms upon the other plate, so that while the spokes are firmly secured into the wood hub, the bands are driven together through the spaces between the spokes, thus firmly binding and securing the whole together in the most perfect manner, and overcoming all the objections existing in other constructions.

To enable others to construct my improvement, I will'proceed to describe the same as illustrated in the accompanying drawings.

A' is a hub, constructed in the usual" manner for carriage-huhs,'and mor tised to receive the spokes, as seen 9 in fig. 2, so as to leave a space-between cach'two of the sp'okes'B B, and the spokesformedwitha shoulder to set upon the surface of the hub, and the spoke made a little wider at the shoulder, and tapering from the shoulder up. 0 is a metallic band, formed to fit closely the spoke, and with projecting arms, a, corresponding to the spaces between each of the two spokes,as seen in figsQZ and 3,'and wheu the spokes are driveninto the hub, then the plate G-is driven on to thchub, and the several arms, a, enter the spaces between the spokes, and closely fill the v said spaces, thus wedging the spoke into the hub, as the spoke, beingithinner, at the upper surface of the arms than at the shoulder, the tendency of the metallic arms (t is to force the spokes tighter into the hub.

Moreor less of the arms a, I furnish with a rivet, d, and upon the opposite side I force another plate, D,

(seen in fig. 4,) being first perforated'to correspond to the rivets 02 upon the plate'C, andlso that the saidrivets pass through the perforations in the plate D, then head the rivets down on to the said plate, securing the two plates together firmly against the spokes upon each side, or secure the .two plates together in any equivalent manner. I do not wish to be understood asbroadly claiming providing a carriage-hub with metallic bands or plates to support the spokes, as this is not new, but v What I do claim as new and useful, and desireto securebyLettcrs Patent, is-, The plate 0, provided with the arms or legs a, combined with the hub A and spokes B and the plate D, when the whole are constructed and united, substantiallydn the manner herein setforth.
