ROTARY CUTTER.
Specification of Letters Patent.
Patented June 1c, 1908.
Application filed March.27, 1906. Serial No. 252,198.
To all whom it may concern: v
Be it known'that we, WARREN O. EvANs and EUGENE H. TAYLOR, citizens of the A United States, residing at Exeter, in the county of Rockingham, State of New Hampshire, andat Lynn, in the county of Essex and State of Massachusetts, have, invented a certain new and useful Improvement in R0- tary Cutters, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to a rotary cutter' which has been designed more especially for edge trimming in connection with boots and shoes, in the manufacture of the latter, but the invention is adapted to be embodied in similar cutters employed for other uses.
- The invention is illustrated in the accompanying drawings, in which latter,
Figure 1 is a,view in elevation of a cutter embodying the invention. Fig. 2'is a view of the said cutter, mainly in section in a central plane extending longitudinally of the cutter-shaft. I
Having reference tothe drawings,-1 designates the cutter-carrying tool-shaft, and 2 is a portion of the bearing for the said shaft.
3 and 31 are heads which are applied to the end of said tool-shaft projecting beyond the said bearing, and 4,4, 4, are the cutter 1 blades mounted between the said heads.
The cutter-carrying tool-shaft 1 .is formed with the tapered bearing-portion 100 fitting the correspondingly tapered end-portion .of theinterior of the bearing 2. The extremity of the tool-shaft rojecting beyond the said bearing is screw-t 'readed as at 101 and 102, the inner (101) of these two threadedportions being slightly larger in diameter than the outer (102). The two heads 3 and31 of the cutter are grooved: to receive the o posite edges-of the cutter-blades, in-usual ashion, and are clamped against said edges to hold the blades in place, as ordinarily- Q In conformity wlth the invention, we render the. cutter-head adjustable u on the shaftl in the direction of the lengt of the latter by the construction which we will now describe. The central 0 ening or eye of the inner head 3 is threade to fit the threaded portion 101 of the shaft 1, and after having the sai wise between'the said heads, and a jam-nut the two heads.
been,turned upon the latter until it has been blades 4, 4,4, between itself and-the inner head 3.
The advantages of the foregoing are the simplicity and strength of the construction and the convenience with which the cutterhead may be adjusted upon the shaft 1 in a direction lengthwise of the'latter.
Weclaim as our invention:-
1. In combination, a screwethreade'd cylindrical carrier, a centrally-threaded head adjustable upon the threaded portion of said carrier, a jam-nut lockin the said head in adjusted osition, a movaile head splined to carrier, cutter-blades seated edgeacting upon the movable head to clamp the blades between the'latter and the relativelyfiXed head.
2. In combination, a screw-threaded c lin drical carrier, a centrally-threaded cadscrewed thereon and adjustable to fix the position of the cutter on the carrier, means or seiparately locking the said head in ad- 'uste position, a movable head, cutterlades seated edgewise between the said heads, and a jam-nut locking the latter head and clamping the said cutter-blades between In testimony whereof we afiix our signatures, in presence of witnesses. i v WARREN C. EVANS.
