IMPROVEMENT IN MAGHINES FOR FINISHING GARD-HANDLES @the Stimme nient tu intime httrts haben mit making im nt ille time.

TO ALL PERSONS T0 WHOM THESE PRESENTS MAY COME:

Be it known that I, INCREASE S. WAITE, of' Huhbnrdst-on, in the county ot"- Worcester, und Stute ot' Massa.- chusetts, have invented e. new und useful Machine for Tenoning` Card-llourd Handles; rand I do hereby declare the seme to he fully described in the following specification, end represented lin the accompanying drawings, of which--` Figure `1 is e. top view, and

Figure e front elevation of such machine.

Figure 3 is n transverse section of' its larger cutter-stock. v v

The purpose of such machine is to ferm upon a card-hoard handle a. dove-tailed tonen havinge curved end.

Figure 4 lis a. top view, and

Fignre-5 a. side elevation of such a. card-handle :ind tenen.

Figure 6 is e. top view, and

Figure 7 on edge elevation of the card-board mertise destined to receive such tenon.

In` the first-named three figures, Aond B denote two cutter-heinds mourftedon the ends ot' two horizontal ond parallel shafts, C D. 'lhe shaft C hns stationery hearings e e, but the shaft D issustnined by an adjustable onrriege, E, held in pleee te the frame F, by which the boxes a a are upheld. Set-screws b I pass through slots c c i'n the carriage E, and screw into n. hed-plnte,f, of th'e frame F,'tl1e .sa-me being to enable the lesser outter head to he moved either toward or away from the larger one,vund.i::ed in position with respect thereto as oceasion may require. Each cutter-heud is n. recessed cylinder', provided\\'itli two cutters, g g or la li., arranged in throats opening through the periphery of the heed. Furthermrehe larger cutter-head has a. flange, z', projecting from it cireumferentiully, as shown in the drawings. "On its front foco the flange is hollowed or grooved entirely around it, und coucentrioally with the cutter-hond. One or more knives or cutters, Ic, extend through the nnge, each being arranged und iixed in a. throat formed therein. The groove of theilang'e has a. semieireular or semi-elliptical section, and the edge of 'the cutter la is hollowcd to correspond therewith, so as to cause each cutter l; to eut o i` the end of the. cardboard handle in a curved form, es represented at Z in iig. 4. Between the two critter-heads is e." rest, G, proridedwith u lip or guide, 1I, which projects up from one side of it, the whole being as represented in the drawings. The upper odge of the seid rest is in, or about in, :t plane passing through the two axes of the cutter-heads. Euch cutter-heed shaft is provided with apulley, m, by which it muy be revolved by 'a belt running around such pulley.

By placing u. cardboard handle on the rest while the cutter-houde are in r11-pid revolution, and forcing it between them and agziinstthe curved farce of the flange, such handle will not only be turned or cut with hevelled edges, but on its ond will be rounded as required, it'heing held against the guide or rest while being so out or reduced.

In a. machine for tenoning cord-board handles, I claim the rota-ry cu'ttter-hced A with the curved concave unge z',A provided with the cutters g und 7c, the cutter-head B, with the cutters 7e, the rest G, and guide H, constructed and operating substantially as' described.
