FRANK R. WOODWARD, OF HILL, NEW HAMPSHIRE, ASSIGNOR OF ONE-HALF TO SMITH & I-IEZMENWAY COMPANY, INCORPORATED, OF NEW YORK, N. Y. 1

GLASS-CUTTER.

mack and State of New Hampshire, 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, of that class of cutter employing a rotary cutter wheel, and means for lubricating the cutting wheel when the same is in operation; the object being to improve the general'construction of this class of cutter, and to provide the head thereof with means for retaining a number of extra cutter wheels which can be readily removed in order to replace a cutter when the same wears out.

Another object of my invention is to improve the general construction of lubricating means for the cutter to provide means for retaining the absorbent material in such a manner that a greater quantity of material can be used in order to obtain a cutter wheel which will not have to be dipped in oil as often as is the case with cutters of this character now in use.

A further object of the invention is to provide novel means for retaining the cutter wheels in the retaining pockets and for holding the bearing pin of the cutting wheel in position.

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, the handle being partly broken away; Fig. 2, is a top plan view of the same; Fig. 3, is a section taken on the line 3-3 of Fig. 1; Fig. 1, is a side elevation of a modified form of cutter, the handle being broken away; Fig. 5, is a top plan view of the same, partly broken away; Fig. 6, is a section taken on the line 6-6 of Fig. 5; Fig. 7, is a side elevation of still another modified form of cutter partly broken away; and Fig. 8, is a section taken on the line 8-8 of Fig. 7.

In Figs. 1, 2 and 3, I provide a head 1 of the usual shape having a cut away portion 2, in which is arranged a cutter wheel 3 mounted upon a bearing 4 secured in open- Specification of Letters Patent.

ings 5 formed in the opposite sides of the cut away portion, as clearly shown, said bearing being of a length so that the ends thereof will be flush with the side walls of the head. lhe head is provided with the usual shank 6 which is secured in the handle 7 in the ordinary manner, and one side of the head is provided with a series of pockets or recesses 8 communicating with each other, by grooves 9 in which is arranged packing material 10, said pockets being adapted to receive eXtra cutter wheels 11, the forward pocket being provided with a groove 12 extending into the cut away portion 2 and is likewise filled with the packing material 13. Packing material or absorbent material 14% is arranged in the cut-away portion 2 of the head, and contacts with the wheel 3 and it will be seen that by dipping the head in oil, the packing material will absorb the oil and apply the same to the cutter wheel, as the same is in use. The pockets form reservoirs which will retain a certain amount of oil besides the cutter wheels, so as to pro vide a lubricating device which will lubricate the cutting wheels for a greater length of time than with glass cutters of this character now in use. In this form, the head is preferably formed of sections, but I do not limit myself to this construction, as the same could be formed of a solid head.

In order to provide means for closing the pockets and grooves, and for maintaining the journal of the cutter wheel in position, so that the same is prevented from moving laterally in the direction it is inserted, I provide the head with a pivotally mounted member 15 which normally is held in position overthe pockets, by friction. the end thereof extending over the journal so that the same is held securely in position. By swinging the member 15 to one side, the journal can be forced outwardly in that direction. so as to remove the cutter wheel when desired.

In Figs. 4 and 5, I provide a head 16 constructed in this instance, of a solid member having a shank which is secured within a handle 17 in the ordinary manner, the upper edge of said head being provided with a longitudinal groove 18 which communicates with a cut away portion 19 formed in the end thereof whereby the head is provided. with a bifurcated end in which is mounted Patented Feb. 23, 1915.

Application filed August 21, 1912. Serial No; 716,231.

a cutter wheel 20 on a journal pin 21 the 16 same have been dipped into a can of oil in order to thoroughly saturate the same. The groove-in this instance, forms a pocket in which a number of cutter wheels can be arranged, and over which the absorbent or packing material is arranged, forming a. reservoir which will retain a certain amount of oil so as to thoroughly lubricate the cutter wheel when in use.

For holding the packing material in position within the groove, and to provide means for preventing the journal 21 from moving in the direction in which it is inserted, in the openings of the bifurcation, I provide the head with a pivotally mounted member 28, the forward end thereof extending over the end of the journal 21 and the rear end is provided with a lateral projection 24 which extends over the groove 18, and maintains the cutter wheel in proper position. In this construction, it will be seen that alubricating glass cutter is formed which is exceedingly simple and cheap in construction, and one in which the cutter wheel can be easily and quickly removed by simply swinging the pivotally mounted member outwardly as shown, in dotted lines in Fig. 4, to allow the journal pin to be moved laterally so as to disengage the cutter therefrom, whereby a new cutter may be readily installed as desired. It will also be seen that the pivotally mounted member maintains a portion of the absorbent material in position as well as the cutter wheels arranged thereunder, and while I have shown the groove extending to the bifurcation it is of course understood that a passage with a closed top can be formed for forming a communication between the groove and the bifurcation in order to receive a wick in order to apply lubricant to the cutter wheel.

In Figs. 7 and 8, I show still another modified form of cutter wheel in which the head 25 is also provide with a bifurcated end 26 which communicates with a groove 27 formed in the top of the head in which a number of auxiliary cutter wheels 28 can be placed so as to have the extra cutter wheel handy at all times; said cutter wheels being retained in their proper positions by a strip of packing material 29 which extends the entire length of the groove and contacts with the cutter wheel 30 arranged in the bifurcation of the head; said cutter wheel being mounted on a pivot 31 which is provided with a yoke portion 32 extending rearwardly-and adapted to straddle the head and maintain the absorbent material over the cutter wheels, as clearly shown in Fig. 7. By this construction, the cutter wheel can also be readily detached as the pivot can be swung outwardly and then drawn laterally so as to remove the cutter wheel therefrom, and when forced into the position as shown in Fig. 7, it will be 1naintained in position by frictional contact with the side walls of the head. As shown in Fig. 7, the groove in the head forms a retaining pocket for additional. wheels, and also a reservoir to retain oil after the same has been forced in a can of lubricant, whereby the wheels will be prevented from rusting and at the same time a larger amount of oil is provided to be absorbed by the packing material which contacts with the cutting wheel in operation, so as to thoroughly lubricate the same.

From the foregoing description, it will be seen that I have provided a glass cutter with an auxiliary wheel retaining pocket which also forms a reservoir for oil, which is supplied directly to the cutting wheel in operation, by absorbent or packing material. It will also be seen that by this construction, an ordinary glass cutter now in use, can be readily provided with my improved construction in order to form means for carrying a number of cutting wheels thereby and for applying lubricant to the cutting wheel in operation.

I claim:

1. A glass cutter comprising a head having a cutter wheel at one end thereof, said head being provided with a pocket to receive an auxiliary cutter wheel, and absorbent material extending from said pocket to the cutting wheel thereof for lubricating said wheel when in operation.

2. A glass cutter, having a head provided with an auxiliary wheel pocket, a cutter wheel mounted in said head, absorbent material extending from said pocket to said cutter wheel, and a pivotally mounted member carried by said cutter for maintaining a cutter wheel within said pocket.
