SANFORD BRAY, OF SOMERVILLE, MASSACHUSETTS.

GLASS-CUTTER.

SPECIFICATION forming part of Letters Patent No. 506,466, dated October 10, 1893.

Application tiled March 1, 1893. Serial No. 464,293. (No model.)

T0 @Mu/hom it may concern:

Be it known that l, SANFORD BRAY, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Glass-Cutters, of which the following is a specification.

My invention relates more particularly to that class of glass cutters provided with a rolling steel cutter-wheel, adapted for cutting rough or rolled glass. The smaller sizes of wheels very soon wear oft and have to be replaced by new ones, which requires considerable time and trouble when the pivots of the wheels are riveted as is usually done.

The object of my invention is to provide a simple and convenient means whereby the worn out cutter-wheels may be quickly and easily removed and new ones readily inserted and secured in position for use without the ald of special tools or a skilled mechanic; also to provide means for renewing the worn away sides of the cutter-block without having to renew the whole tool; and my invention consists in the construction, combination and arrangement of the dilerent parts of the dev1ce as hereinafter more particularly def scribed and claimed.

In the drawings, Fig. lis a perspective view of a glass cutter constructed according to my invention, in position ready lfor use. Fig. 2 is a front elevation partly in section. Fig. 3 is a side elevation showing the parts disconnected and removed preparatory to changing a worn cutter-wheel for a new one.

A represents the handle which is formed of wood or metal, B, a boss on the handle, and C, arubber sleeve on the iinger-grasping portion of the handle. The cutter-block D is formed with a slot in its end within which the steel cutter-wheel E is pivoted on the journal S. This journal S has an arm t bent at right angles with the journal, extending backward and resting against the side of the block. A clamping screw n screwed into the hole m in the side of the block secures the journal rmly in position without riveting the ends. When a wheel is worn out and it is desired to remove it, the clamping screw may be simply loosened and the journal readily withdrawn and a new wheel substituted for the old one, and the journal secured as before. The end of the block becomes worn oft at the corners, more or less, by use, and in order to save the necessity of an entirely new block when so worn, I prefer to make the block with a removable or pivoted side-plate Gr on at least one side, as shown in the drawings. One side-wall of the end slot within which the cutter-wheel is pivoted is formed by the thinned projecting portion which extends beyond the shoulder a and having a hole t' adapted to receive one end of the journal s. The other side-wall of the slot is formed by the projecting end of the side-plate Gr. The side-plate G may have a journal hole corresponding to hole t' in the projecting end of the block' D, but I prefer, instead, a slot e. When the ends become worn'the shoulder a may be tiled back and the slot c made deeper and the hole t' made anew; or slotted also like slot e.

It desired, the cutter-block could be composed ot' three thicknesses instead of two as already described, in which case there would be a plate with projecting end corresponding to plate G on the opposite side, the middle plate being shorter and its end forming the shoulder a.

lIt will be evident that the plate G may be made shorter, and the block D formed with a shoulder which fits the end of the plate, so that only a single screw need be employed, the screw n serving both to clamp the pivot or bent journals t, and to hold the plate G in a rigid position with the cutter-block l).

What I claim as my invention is l. A cutterholder consisting of the combinationV of a cutter-block with slotted end adapted to receive a cutter-wheel, a journal for the -cutter-wheel having its bearings in.

the walls of said slot and having a bent arm, and a clamp-screw whereby the journal may be secured firmly in position, and removed to allow a change of cutter-wheels, substantially as described.

2. In a glass cutter, the combination of a cutter-block composed, vin part, of a removable side-plate, the combination block having a slotted end adapted to receive Va cutterwheel, a cutter-wheel within said slot, ajournal for the cutter-wheel having its bearings ICO in the walls of said slot and having a bent arm and a clamp-screw whereby the journal may be secured rmly in position, and 1emoved to allow a change of cutter Wheels, substantially as described.

In a glass cutter the combination of a cutter-block composed in part of removable side-plates, the combination block having a slotted end adapted to receive acutter-wheel, and a cutter-wheel with a journal having its bearings Within the Walls of said slot, substantially as described.

4. In a glass cutter, the combination of a
