IMPROVEMENT IN TOOL FOR FITTING BANDS 0N HUBS.

TO .ALL WHOM IT MAY CONCERN:

I Be it known that we, CHARLES E. S'ronaof Amesbury, and ALFRED HERBERT, of Salisbury, in the county of Essex,` and State of Massachusetts, have invented a new and useful Improvement in Hub-Band Fitters; and we do hereby declare that the following is a full, clear, and exact description vthereof, which Willenable others skilled in thc art' to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in whichl The drawing represents a .side view of our invention, shown as applied in practice. Similar` letters ot' reference indicate like parts. p Our invention is an improvement npon a tool for fitting hub-bands, which has been in use for some years. Said tool consists of a single handle, recessed, and provided with two cutters arranged at right angles to each other. It was foundv diiicult to execute work satisfactorily with this tool, however, for the reason that it was not provided with a/clamping-devicc. The object of our invention is to remedy this defect by supplying a clamping-lever, by means of which the fitting of hub-bands is rendered easy.

Heretoore, hub-bands were fitted to the' hub by chipping oit` a portion of the wood with a hammer and chisel, until the end of the hub was of the right perimeter to receive the band. VThis method was laborious, requiring both skill and time to accomplish the proper fitting of the band.

By our invention, the operation of chipping ofi the hub with'a chisel is dispensed with, and a continuousv shaving is pared from the hub bye-imply turning the wheel on its axle, and holdin-g the tool in proper positionupon the hub, as will hereinafter be duly set forth.

The invention consists of two handles, -A and B, pivoted together 'oy means of the arm C, forming part of the handle A, together with other devices perfecting the whole, and which will now be described.

The handle B is provided with a set-screw, a, which is screwed into any one oi' the several holes b b b, formed in theV arm C, as shown, and, by means of `this set-screw and the said' holes, the handles are pivoted together, at suitable distances apart, to adapt the tool to different-sized hubs. I

The handle B is formed with an angle or concave, as shown at c c c, for the purpose of conforming suiciently to4 hubs of different sizes, and to bear upon the surfaces ofthe hubs at two points, and thereby be enabled to be held firmly in a iii/red position against the hub during theV operation'of cutting or paring the same.- p

The handle A is formed with a recess, E, for the escape ofthe paring or shaving cut from the hub by the vcutter (Z, bolted or otherwise afxed to the said, handle, so that its cutting-edge shall project sufficientlyto encounter the hub, as indicated in thedrawing.

A marking-cutter c 'is fitted in a dove-tailed slot in the handle A, and presents its point to the hub to mark and cut a vertical' incision into the hub, whereby the ilnt cutter (Z is enabled to operate more eiectively in cutting a lclean Vsent for the reception ofthe band. i i

Themarking-cutter e is clamped in position by any suitable device, as the lateral .set-screw, shown dotted ntf.

The ilat cutter is slotted to enable it 'to be set to eut more or less deeply, as required, and its set-screw, g, is within the slot. l l

In the operation of fitting the band, theptool is applied, as shown in the drawing. It is'held by the handle, and the wheel revolved upon its axle until a snilieient thickness of wood has been cut oii' to enable the band to fit tightly upon the hub. .y i

We are am aware that a hub-band fitter, consisting of a single handle, recessed, and provided with two cutters arranged at right angles to each other, has been used before, -but this we disclaim, as it forms no part of our invention. I

Having thus described our invention, we claim as new, and desireto secure by Letters Patent- The handle B, curved at c c c, and adjustably pivoted'to the extension C `ofthe handle A, by means oi` tho set-screw a fitted into either one of a series of holes, b Z1 6, formed .in said arm C, substantially as and for the purpose herein shown and described.

- CHARLES E. STONE,

ALFRED HERBERT.
