MOUNTING For. GLAss-oUrTEns.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed February 26, 1914, Serial No. 821,162. Renewed July 1, 1915. Serial No. 37,590.

To all whom it may concern:

Be it known that I, SAMUEL G. MONOE, a citizen of the United States, and a resident of Unionville, in the county of Hartford and State of Connecticut, have invented a new and Improved Mounting for Glass- Cuttens, of which the following is a full, clear, and exact description.

The invention relates to glass cutters of the cutting wheel type, and its object is to provide a new and improved mounting in which the glass cutting wheel is journaled, the mounting being very simple and durable in construction and readily attached to or removed from any desired form of holder.

In order to accomplish the desired result use is made of a flat piece of metal, doubled up to form spaced side members, between the free ends of which extends the cutting wheel, the said free ends of the side members being provided-with registering apertures for the reception of the arbor on which the cutting wheel is mounted to turn.

A practical embodiment of the invention is represented in the accompanying drawings forming 'apart of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the mounting as applied in a handled holder;

Fig. 2-is an end View of the same; and

Fig. 3 is a perspective view of the cutting wheel and its mounting.

The tool handle is provided with a socket in its end as shown in Fig. 1. The mounting A for the glass-cutting wheel B is formed from a piece of flat metal doubled up to provide spaced side members A, A between the free ends of which extends the cutting wheel B, as plainly indicated in the drawings. The free ends of the side members A, A of the mounting are provided with registering apertures for the reception of the arbor or spindle C on which the wheel B is mounted to rotate, it being understood that the ends of the said arbor C are upset with a suitable tool to securely fasten the arbor C in position in the said members A and A It will be seen that by constructing and mounting in the manner described, the cutting wheel B is held against sidewise movement by the side members A, A and the arbor C' is firmly supported in the side members A and A thus forming an exceedingly strong mounting for the wheel B.

The mounting as described can be used in holders of various forms, for instance, as shown in Figs. 1 and 2, use is made of a holder D provided with a handle D, on one end of which is screwed a ferrule D terminating in a socket D for the reception of the mounting A. The socket D is of a width corresponding to the distance between the outer faces of the side members A and A so that the mounting A fits snugly between the sides of the socket D and against the bottom thereof, as plainly indicated in Fig. 2. y

In order to limit the rearward movement of the mounting A in the socket D use is the back of the-said clamping bar F is engaged by a set screw G screwing in a thickened portion D of the socket D The rear end of the clamping bar F is mounted to slide freely on the pin E so that the clamping bar is not liable to drop out of the socket D It is understood that by screwing up the set screw G the clamping bar F is firmly pressed in contact with the side members A and A of the mounting 'A to securely clamp the latter in position in the socket D and on unscrewing the set screw G, the mounting A can be readily removed from the socket and replaced by a new one in case the cutting wheel is worn out.

As shown in Fig. 3, the sharpened periphery of the wheel B projects beyond the plane of the front and rear faces of the side members of the mounting, as well as beyond the ends of the same so that the mounting A can be used independently of the holder and in any position from the vertical to the hori- Zontal.

It is understood that in practice the glasscutting wheel in its largest size for cutting owner of a glass cutter can readily remove the mounting having a worn out wheel from the, holder and place another mounting with a new wheel in position in the holder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: 7 1; A glass cutting tool, comprising a holder'or handle having a rectangular socket, a mounting carrying a cutting wheel and arranged in said socket, said mounting being of less size than the socket and having its sides fitting against the side walls of the said socket throughout its length, a clampbar permanently and loosely mounted in the socket between the mounting and an end wall of the socket, and a clamp-screw mounted in the socket and engaging the clamp bar to force it against the mounting.

2. In combination, a holder provided with a socket, a mounting formed from a piece of flat metal doubled up to provide spaced parallel members, an arbor held in the free ends of the said members, a glass-cutting wheel mounted to turn on the said arbor and extending between the said mounting, the

latter fitting into the said socket, a pin in the said socket to limit the inward movement of the said mounting, a clamping bar in the said socket and engaging the said mounting to clamp the latter in position in the socket, the said clamping bar being mounted to slide on the said pin, and a set screw screwing in the said socket against the said clamping bar. a

3. In combination, a holder provided with a socket, a mounting formed from a piece of flat metal doubled up to provide spaced parallel members, an arbor held in the free ends of the said members, a glass-cutting wheel mounted to turn on the said arbor and extending between the said mounting, the latter fitting into the said socket, a pin in the said socket to limit the inward move ment of the said mounting, a clamping bar in the said socket and engaging the said mounting to clamp the latter in position in the socket, the said clamping bar being mounted to slide on the said pin and the said clamping bar being U-shape in cross section and having its side bars seated on the edges of the said mounting members, and a set screw screwing in the said socket against the said clamping bar.

4;. A glass cutting .tool, comprising a holder provided with a rectangular socket, a mounting carrying a cutting wheel and arranged in the socket, said mounting being of less size-than the socket and having 1tsides fitting against the side walls of the said socket throughout its length, a stop for limiting the inward movement of the mounting, a clamp-bar permanently and .slidably mounted in the socket at one side of the mounting, and a clamp-screw mounted in the socket and engaging the clamp bar to force it against the mounting.

5. A mounting for a glass cutter, consisting of a piece of narrow fiat metal bent upon itself to form an elongated inverted U- shaped body having flat parallel members spaced a short distance apart, an arbor secured in the free ends of the members of the body, and a glass cutting wheel mounted to turn on the arbor and having its periphery projecting beyond the ends of said members, beyond the planes of the front and rear faces thereof.

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.
