UNITED sTATEs PATENToFEIcE TOUL FOR FIISHING FELIIIEIS.` l

Specification of Letters Patent N o. 26,392, dated Decemberpl, l f

To all whom 'it` may concern:

Be it known'that I, CHARLES I-I. DENisoN,

`of Guilford, in the county of Windham and State of Vermont, have invented a new and useful Machine for Manufacturing and Finishing the Fellies of the Wheels of Carriages and other Vehiclesnot Known or Used Be fore my Invention Thereof; and I do hereby declare that the following is a full and true description of said invention. l

The obj ect and purpose of my machine is to square the external or convex as well as the internal or concave surface ofthe felly;`

i y and further, to dress and round the internal corners of the fellies between the spokes having the square surface at each spoke to sus-` tain the pressure of the shoulder ofthe ""spoke. This has usually been done by hand.

I do it by machinery, and first as to round ing the said corners, after the fellies have been squared, I subject them to the action of revolving cutters (A A in the accompanying drawing) carried by an arbor (B Figs. I

and II). This arbor when in use rises perpendicularly through a table or bench, although it is in the drawing for convenience represented as lying horizontally. Fig. I represents this arbor with the cutters A. adjusted to it and firmly held in grooves prepared for them, by the action of the nut (C) acting on the screw D. But in order to have a square and broad place to receive and strongly support the shoulder ofeach spoke (E, Fig. IV) I make use of the following device: A metallic washer or collar (F, Figs. I and II) holds in its grooves (G)` the cutters, and this washer being changed for one either thicker or thinner adapts the machine `for nishing a broader or narrower felly. This washer prevents the cutters going any deeper than is desirable as it traverses the already squared internal surface of the felly. But to leave the broad places at the spokes (E, Fig. IV) the holes for the spokes are first bored, each in its proper place, and as each section of the felly `is `upright pins to "hold, the `convex"surface of` MILLER, or BRA L about to` be placed against the` cutters iron gage (Fig. V) isused., This gagefhav ing a cylindrical projection` (H) which fits the holes bored in` the felly for the spokes l is easily heldin place by` a claspof the opei ators hand. This gage`receivng onfits in clined surface (I) the action ofthe washer" (F, Fig. I) holds thecollars from the wood at the place to be occupied by theyspoke,"V and consequently leaves a square plane fo the shoulder of the spoke, and as the `vvashe F traverses downthe inclinedplane (I, Fig. V) the cutters gradually depress their" cuta ting of the internal corners ofthe felly. l

To square the internalsurfacelofthe felly,` instead of using the cutters with` curved g edges I putonto thewgarbor onepairof straight edged cutters as shown (at. J, Fig VI) and to prevent these cutters from pene` trating too deepandfto secure anyevenfin-` O'age (shown at Fig.VII). Thecentral ori-V ce (K) of this collar `lgageis made to fit without pinching the.` well turned arbor B (Figs. I andIL) so that whether the oper-` ator presses the felly` evenlyornotthe `coll` l lar gage will turn and` allowthe cutters to i l" find the wood. To even and square theeX- ternal surface of the felly, the same straigh edged cutters are employed and a similar co lar gage, except that it merely has two stron the fellies from the centers.A i What I claim as myinvention to secure by Letters Patent is-fp l. The above` described washer andft above described iron gagelfor trimmingan shaping the internalsurface of fellies.,` y 2. The above described collar-gages squaring the external and. internallcurved` p surfaces of the felly.` y 1` -l f Q.` I-IBDENISON Witnesses: .y "l f I. DOERVBRADLEY H.' I-I. WHEIEmiR.`
