GLASS-CUTTER.
Specification of Letters Patent.
Patented Oct. 17, 1916.
Application filed July 15, 1914. Serial No. 851,209.
, T all whom it may concern:
Be it known that I, MAXIMILIAN SIDON,
a citizen of the United States, residing at The cutting wheel, according to my invention,
as here shown, is in the form of a single truncated cone with its cutting edge lying in the plane of the base of the cone, and its opposite face adjacent the wheel supporting portion of thehandle, thereby forming a cutting wheel with a naturally formed cut ting edge which may be sharpened from time to time on an oil stone by placing the more extended face (base of the cone) flat against the stone, and by virtue of the arrangement whereby the holder is on one side only of the wheel, such sharpening may. be done without removing the wheel from its holder. Cutting wheels so made and supported will last a very long time by reasonable usage, and, moreover, give the operators using them the advantage of keeping their cutting wheels just as sharp as the glass to be cut demands. The form of cutting wheel generally employed in this class of tools is in the form of a double truncated cone, the cutting edge of which lies between the planes of the outer flat faces of the wheel, the said wheel turning, in a slot at one end of its holder.- Such wheels dull quickly, and owing to the difficulty of sha rpening them in the holder, are. replaced in said holders, as they become dull, until the worn out pin hole in which their supporting spindle is carried makes this impossible. This sharpening of the wheels, however, is not usually the job of the glass cutting operator, and the new wheel often proves unsatisfactory for the glass on hand.
This invention comprises also in combination with the improved form of cutting wheel and manner of mounting the same, a
form of handle which facilitates the manipulation of the cutter. Such wheel being more or less offset with respect to its support, may be more readily held with the plane of the cutting edge perpendicular to the plane of the glass and otherwise man1pu lated, by providing the handle also with offset supportlng means for the hand of the operator.
Inorder to more fully describe my said invention, reference will be had to the accompanying drawings, wherein Figure 1, shows in front elevation a glass cutter provided with a form of my improved handle and cutting wheel; Fig. 2, a side elevation thereof;Fig. 3, a front elevation v of a glass cutter provided with my improved cutting wheel, but without the pressure extensions or arms on'the handle; Fig. 4:,a front elevation of a glass cutter having a wooden handle provided with pressure extensions or arms according to my invention, and also with a form of my improved cuttingwheel; Figs. 5, 6, and 7 fragmentary detail sections showing various forms of my improved cutting wheel and manner of supporting the same, and Fig. 8, a detail top plan view of the pressure extension member made in a form to be clamped to the handle.- I
Referring first to the form of my invention as shown in Figs. 1 and 2, 1 indicates the handle of the glass cutter; 2, pressure extensions or finger rests consisting of lateral arms rigid on the handle 1; 3, the wheel supporting extension, and 4, the cutting wheel. In this form of the tool the handle 1, pressure extensions 2, and wheel supporting extension 3, are all made in one piece, preferably of cast metal. The wheel supporting extension 3 may be of substantially the same form as commonly employed in this class of tools except as to that portion immediately EtdJZICGIlt the cutting-wheel. .In the common form of glass cutter, this extension is slotted, and thewheel is supported upon a pin carried by the extensions on each side of the wheel, the wheel itself being inthe form of a double truncated cone with the cutting.
edge formed by the bases of the two cones.
According to my invention, as here shown,
r be set on an angle, as the wheel 4P, shown with the face of the wheel opposite its cutting edge or base, adjacent one side of the extension 3, which latter may be cut away as at 10 to bring the cutting edge of the wheel more nearly under the central longitudinal axis of the handle. The extension 3 may also be provided with the usual marginal slots 11.
My improved cutting wheel may be made solid, as'the wheel 4*, shown in Fig. 5, but is preferably dished or cupped as shown for example in Figs. 2, 6 and 7, so as to allow the entire cutting edge to be laid fiat against a plane surface as that of an oil stone.
Instead of mounting the cutting wheel with the plane of its cutting edge parallel to the adjacent side of extension 3, as shown in Figsal, 2, 3, 4L, 5, and 7 the wheel may in Fig. 6. The latter figure also shows an alternative form of pin for carrying the wheel. In this case, the head of the pin and bearing surface are combined in a coneshaped portion 9.
In the tool shown in Fig. 3, the handle proper 1 is of the common form, but the cutting wheel and manner of mounting it are of novel construction, being the same as shown in Figs. 1 and 2.
In Fig. 4:, I have shown a tool embodying the same form of cutting wheel and manner of mounting the same as shown in Figs. 1, 2 and 3, and also embodying a handle provided with my improved pressure extensions. The handle 1 in this case, however, is of wood attached to a metal wheel supporting extension 3, and the pressure extensions or arms are formed by a pin 2 passed transversely through the handle, but held friction tight therein.
In Fig. 8, I have shown a form of support or offset for the handle, comprising a yoke 2 having arms 2 and a set screw 2 adapted to be slipped on the handle of the tool and clamped thereto, and which may be substituted forthe supports 2 or 2 herein shown.
Other modifications of my invention may be made without departing from the spirit thereof.
l Vhat I claim is 1. As an article of manufacture, a glass cutter for manual use comprising a holder having a handle, a cutting wheel the material of which lies wholly on one side of its cutting edge, and means supporting said wheel on said holder with the plane of the cutting edge of said wheel wholly to one side of said holder, whereby the face of the wheel in the plane of its cutting edge and extending transversely of its axis of rotation may be laid fiat against a plane surface, substantiallly as described.
2. As an article of manufacture a glass cutter for manual use having a cutting wheel in the form of a single truncated cupped cone the base of which coincides with the cutting edge of the wheel, a holder having a handle, and means wholly to one side of the plane of the base of the cone rotatably supporting said wheel with its cutting edge wholly to one side of said holder, whereby the face of the wheel constituting the base of the cone may be placed fiat against a plane surface, substantially as and for the purpose set forth.
3. As an article of manufacture, a glass cutter for manual use comprising a holder having a handle provided with one or more lateral hand supporting arms, a cutting wheel the material of which lies wholly on one side of its cutting edge, and means supporting said wheel on said holder with the plane of the cutting edge of said wheel wholly to one side of said holder, whereby the face of the wheel in the plane of its cutting edge and extending transversely of its axis of rotation may be laid fiat against a plane surface, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
MAXIMILIAN SIDON.
