LANDON 1?. SMITH, OF NEW YORK, N. Y., ASSIGNOR TO SMITH. & HEMENW'AY COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORFORATION OF NEW YORK.

GLASS-CUTTER.

Application filed June 8, 1912.

To all whom it may concern Be it known that I, LANDON P. SMITH, a citizen of the United States of America, residing at New York, in the county of New fork and State of New York, have invented certain new and useful Improvements in Glass-Cutters, of which the following is a specification.

This invention relates to certain new and useful improvements in glass cutters and more particularly to that class of cutters which is provided with a series of cutting wheels arranged in such a manner that any one of the cutting wheels may be moved into position to be used; the object being to provide means for lubricating the cutting wheels of this class of cutter whereby each wheel will be normally in contact with an absorbent swab so that when the same is in operation it will. be thoroughly oiled as it travels over the glass to be out.

Another object of the invention is to provide a glass cutter which is exceedingly simple in construction, the lubricating means being so arranged within the wheel-cutting member that it will be retained in position by the cutting wheels.

Another object of the invention is to provide lubricating means in the form of a ring or a series of rings arranged within the annular grooves of the wheel-carrying member in such a manner'that the periphery of each wheel will be thoroughly lubricated when in operation; said means also maintaining the idle cutting wheels in good condition so that when thrown into operative position they will be in such a condition that they will operate readily, thereby overcoming the difliculties with this class of machines now in use, as when one of the wheels are used for any length of time, and the remaining wheels are idle they become rusty when subject to any dampness, and it is sometimes necessary to remove their bearing pin in order to allow them to operate.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings-Figure 1, is a side elevation of a glass cutter constructed in accordance with my invention; Fig. 2, is an edge elevation of the same; Fig. 3, is an enlarged elevation of the wheel carrying mem- Speeification of Letters Patent.

ber detached; Fig. at, is a section taken on the line l l of Fig. 3; Fig. 5, is a section taken on the line 5-5 of Fig. 4; and Fig. 6, is a detail section through the wheel carrying member showing a slightly modified form of lubricating members co-acting with the cutter wheel.

In carrying out my improved invention I employ a head 1 which is provided with the usual notches 2, and at one end has an integral shank 3 on which is arranged and secured in the ordinary manner, the handle a. The opposite end of the head 1 is provided with a circular recess 5 the side wall of which is provided with a central aperture 6 through which extends a binding screw 7 having a threaded outer end adapted to pass through the threaded bore 8 of a circular wheel-carrying member 9, and secure the same in position within the recess as clearly shown in Fig. 1.

The circular member 9 is provided with a peripheral circumferential groove 10, the bottom wall of which forms a seat for a circular ring 11 of absorbent material, which is preferably made in the form of a washer and forced into position so as to surround the hub portion of the member 9. The absorbent ring 11 can be formed of any suitable material, but as herein shown is formed of felt, and is adapted to absorb lubricant when the same is submerged in order to lubricate-the cutting wheels as will be hereinafter fully described.

The wheel-carrying member 9 is provided with transverse bores through which extend rivets 12 forming bearings, and upon which the cutting wheels 13 are journaled, which are of such a size that the peripheral edge extends out beyond the edge of the member 9 in order that the same can be used a cutter. The cutting wheels partly embed themselves within the absorbent ring 11, as clearly shown in Fig. 4, and retain the ring in position, and as shown I have provided the member 9 with six cutting wheels so that after one has worn out, the wheel-carrying member 9 can be rotated so as to bring another one of the cutting wheels into position to be used. It will be seen that a portion of each wheel is maintained in contact with the absorbent ring at all times, so that the wheels will be kept in an oiled condition, and so that the wheel which is being used will be thoroughly lubricated as the same rotates in contact with the lubricating member.

In the modification shown in Fig. 6, the carrying member 9 is formed in substantially the same manner, but instead of employing a single absorbent ring, I arrange within the groove a pair of absorbent rings 14 between which the cutting wheel rotates so as to thoroughly lubricate the wheel when in use, and by this construction, the life of the absorbent ring is greatly increased, and the wheel is thoroughly lubricated at all times. Of course any number of lubricating rings can be employed, but I have found that one large ring or two small rings arranged, as clearly shown, will be sufficient to absorb sufficient lubricant to thoroughly lubricate the cutting wheels.

From the foregoing description, it will be seen that I have provided a magazine glass cutter with means for lubricating the cutting wheel in such a manner that the cutting wheels not in operative position will be prevented from rusting. It will also be seen that by the construction set forth the lubricating means is maintained in proper position by the cutting wheels, so that after the same has been placed in position with the groove of the member, and the cutting wheels secured in position, the lubricating means will be held in proper position without additional fastening means.

I claim:

1. A glass cutter comprising a head, a movably mounted cutter wheel carrying member carried by said head, a lubricating ring carried by said head, said ring contacting with each of said cutters.

' 2. A glass cutter having a revolubly mounted wheel-carrying member provided With an annular groove, a plurality of cutthreaded bore, ascrew working in the aperture of the head extending into'the threaded bore of said member for securing said member in its adjusted position therein, said member being provided with anannular groove in its periphery, a plurality of cutting wheelsmounted in the groove of said member, and a lubricating member arranged within the bottom of said groove in contact with each of said cutter wheels.

4. A glass cutter having an adjustably,

mounted cutter carrying member, said member belng provlded with an annular groove, a mug of absorbentmaterial arranged within said groove, and a plurality of cutters independently mounted within. said groove engaging said ring for retaining said ring in position therein.

5. In a glass cutter, the combination with a head having'a recess, of. a circular member adjustably mounted within said recess, said member being provided with a plurality of cutting wheels extending beyond the peripheral edge thereof, and a central lubricating ring carried by said member, and engaging each of said cutter wheels.

In testimony whereof I afiix my slgnature in presence of two witnesses.
