WILLIAM Gr. STEBBINS, OF' MONTAGUE, MASSACHUSETTS, ASSIGNOR TO MILLERS FALLS COMPANY, OF MILLERS FALLS, MASSACHUSETTS, A\ CORPORATION OF MASSACHU- SETTS.

` To all whom 'it may concern:

l Cutters, of which Be it known that I, WILLIAM Gr. STEBBrNs,

of Montague, in the `county of Franklin and `State of Massachusetts, have invented certain new and useful, Improvements in Glassthe following 1s a specification.

This invention relates to a glass cutter` having a plurality of edged cutting wheels of hardened steel mounted in a circular series on a head which is rotatively connected with a frame or holder, and is adapted .to be clamped to the holder with either of the cutting wheels in position for operation.

The invention has for its object to provide certain improvements in the construction of the head, and in the means for mounting the edged cutting wheels therein, and in the means for adjustably securing, the head to the holder', the said improvements being intended to facilitate theassemblage and separation of the parts, and the substitution of new parts, especially the studs orV journals on which the cutting wheels are mounted, for others which. may have been broken or worn.

\ The invention consists in the several improvements which I will now proceed to describe and claim. Y Y

Of the accompanying drawings forming a part of this specication, Figure 1 represents a side elevation on an enlarged scale of a glass cutter embodying my invention. Fig. 2 represents an edge view of the same. Fig. 3 represents a section'on line 3 3 of Fig. 1. Fig. 4 represents a view of the inner side of the head or turret, hereinafter referred to, removed from the holder. Fig. 5 represents a fragmentary section on line 5-i-5 of Fig. l,

The same reference characters indicate the same parts in all the figures.

In the drawings, 12 represents a'frame or holder which is preferably a flat-sided plate provided at its inner end with a shank to which a suitable handle 13 is secured. In the outer end portion of the holder 12 is formed a lcircular recess 14, the bottom of said recess forming a seat for theinner side of a circular head or turret 15. TheV outer end of the holder 12 is cut away at 16, so that a portion of the periphery of the turret projects outwardly from the outer end of the holder, as shown in Figs. 1, 2, and 3. This formation ofthe head, while not absolutely essential, is preferred because it perspeciaeaeion of Letters Patent.

GLnss-CUTTER.

Vmits ya suitable projection of the operating edged cutting wheel from the outer end of the holder, as hereinafter described.

VThe turret is provided with a deep peripheral groove 17 which is located between the vls; '1

outer and inner Vsides of the turret, and is adapted to receive a plurality of edged cuttingwheels 18, of which any suitable number may be employed, seven being shown in this embodiment of the invention. inner side of the turret is formed an annular recess19 which is concentric with the axis of the turret. `The cutting wheels 18 are journaled 'upon bearings or studs 20 which areinserted in holes formed for their reception in the turret, and extend across the groove 17, the inner ends of said studs proj ecting into the annular recess 19. The studs 20 are provided with suitable heads at their inner ends, said heads being contained in the recess 19, and'being confined in said recess by the seat 14; when the head is connected with the holder 12, the said seat and the .walls of the recess 19 constituting an annular chamber which contains the heads of the studs. Said heads 'are preferably formed as arms 21, which are integral with the studs 20, the studs and arms, or heads, being` formed by bending suitably shaped metal blanks into substantially theform shown in Fig. 5. The turret is provided with a screwthreaded shank or bolt 22, which is preferably integral with the turret, and projects from the inner side thereof through an orifice formed for its reception in the holder 12. represents a clamping nut engaged with the bolt 22, and adapted to secure the turret rigidly to the holder. When the cutter is adjusted for use, one of its cutting wheels is brought into position to project from the vouter end of the holder, as indicated in Fig. 1, the turret being then rigidly secured by tightening the nut 24. The cutter is used by pressing the `projecting wheel against the glassV to be cut, and moving it along the same in the usual manner. When the projecting wheel has become worn, the turret may be partially rotated to bring the next wheel into position for operation, and

so on.

It will be seen that when the turret is removed from the holder, the recess 19 and the heads 21 are exposed, as shown in Fig. 4, so

Vthat said heads and the studs may be readilyA IOC and conveniently reinoiied troni and applied to the turret, the heads being securely conlined by the operation ot' applying the turret to the holder. their the turret has been charged with cutters, and is 1neld with its Vrecessed side uppermostv7 there is no liability ot the displacement ot the cutting wheels and the studs on which they are Journaled the wheels being securely confined in the i groove l? by the studs, and the studs being held in place by the confinement ot their jects vtroni the recessed side et the turret; consequently, when the recessed side is uuret and the other studs. rlhe heads ou the studs :iid the sides ol the chamber lf) con` stitute means tor detaehably securing the studs independently ot each other. while the sides ot the groove 1T constitute means lor coiiti'niiigl` the cutters ou the studs.
