Description
May 17, 1949 G. A. PHILIPPE 2,470,444l
GLASS CUTTER Filed Feb. 21, 1946 IN VENTOR Patented May 17, 1949 UNITED STATES PATENT OFFICE GLASS CUTTER George A. Philippe, Fort Smith, Ark. Application February 21, 1946, Serial No. 649,170 6 Claims. (Cl. 49-52) The invention relates to glass cutters, particularly the manually operated type, and has for its object to provide a device oi this kind adapted for making relatively long cutting strokes against a straight edge, and constructed in a manner l the yoke to a position in the plane of the axis of the handle, and at the same time allowing lateral misalinement of the handle in relation to the yoke during the cutting operation.
A further object is to provide means whereby the spring means cooperating with the yoke shaft can be adjusted for adjusting the yoke into the plane of the axis of the handle.
A further object is to mount the diamond carrying carriage on trunnions within the yoke, thereby allowing side tilting of the yoke as well as angular positioning of the handle in relation to the yoke during the cutting operation.
A further object is to hingedly mount the handle member on the handle head, and to provide means whereby the handle may be locked in various angular positions in a vertical plane in relation to the head.
With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings:
Figure 1 is a vertical longitudinal sectional View through the glass cutter.
Figure 2 is a top elevation.
Figure 3 is a top elevation of the glass cutter, showing the handle at an angle to the yoke and carriage, and the carriage against a straight edge.
Figure 4 is a transverse sectional view taken on line 4-4 oi Figure 5.
Figure 5 is a perspective view of the diamond carrying carriage.
Figure 6 is a horizontal sectional View taken on line E-G of Figure 1.
Figure '7 is a perspective View of the handle head, parts being broken away to better show the structure.
The device is particularly adapted ior cutting large sheets of glass, where the handle I is necessarily long and therefore the operator can not pull in a straight line, particularly when the operator has to reach over the table a great distance, and also as the tool approaches the end of its cut, and the tool is designed so the cutting carriage will remain against the straight edge 2, no matter whether the pull is absolutely a straight one or not. The handle I is hingedly connected at 3 by a biiurcated member ll to the handle head 5, and threaded through the biiurcated portion 4 is a threaded shaft 6, which, when threaded inwardly, engages the eye 1 of the head and holds the handle at a predetermined upward angle in relation to the cutting tool. The head 5 is provided with a chamber 8 having spaced anti-frictional bearings 9 therein, and rotatably mounted in said bearings is the vertical yoke shaft I0. Yoke shaft I0 is provided with a kerf II, in its upper end, which kerf receives the portion I2 of a coiled torsion spring I3. The other end of said spring is anchored at I4 in one oi the slots I5 of a rotary adjustable sleeve I6, which sleeve is provided with an outwardly extended headed screw Il, extending through the slot I8 in one side of the head. By providing the screw I'I, the sleeve I6 can be rotatably adjusted for varying the tension of the spring I3 and maintains the yoke shaft I0 in any desired rotatable position, and the yoke I9 in the plane of the axis oi the handle. In other words, aiter a cutting operation, the yoke will immediately assume a position in the plane oi the axis oi the handle. By providing the additional anchoring slots for the spring additional tension adjusting means is provided in connection with the adjusting screw Il.
The lower ends of the arms 20 of the yoke I9 are provided with ltrunnion screws 2I, and on which trunnion screws the diamond ferrule carrying carriage 22 is rockably mounted transversely in relation to the yoke I9. One oi the trunnion screws 2I engages in a recess or bearing 23 of the transverse portion 24 of the turpentine cylinder 25, and the portion 24 is rigidly held in adjusted position by a screw 26. Extending transversely of the carriage 22 is a rotatably adjustable plug 21 having mounted in a transverse aperture through the plug the diamond ferrule 28, and the diamond ierrule is held in adjusted posi.
tion by a set screw 29, extending into the plug 21, and the plug is in turn held in adjusted position by a lock nut 30. It will be seen that the diamond ferrule may be adjusted to proper angle as well as the turpentine cylinder 25, having a swab 3| for depositing turpentine on the glass in advance of the diamond 32.
Referring to Figure 3 it will be seen that the handle l can assume an angular position to the straight edge, and at the same time the side of the carriage 22 will remain in engagement with the straight edge, and the yoke can oscillate from side to side on the trunnions 2| without affecting the position and engagement of the side of the carriage with the straight edge, hence it will be seen that the accurate cutting is not affected by the variations of angular pull by the operator on the handle l, and that accurate cutting is obtained at all times.
The invention having-been set forth what is claimed as new and useful is:
1. A glass cutter comprising a handle member, a head to which said handle member is connected, a cutter carriage yoke below said head, a vertical shaft carried by the upper portion of said yoke and rotatably mounted in the head, yieldable means for urging said yoke towards the plane of the axis of the handle, and a cutter carrying carriage rockably mounted within the yoke on pivotal points in the plane of the yoke.
2. A device as set forth in claim 1 wherein the yieldable means within the head for urging the yoke towards the plane of the handle comprises a coiled spring having inner and outer convolutions extending around the shaft carried by the yoke and disposed in the head, the inner convolution of said coiled spring being anchored to the shaft, a rotatably adjustable sleeve Within the' head, the outer convolution of said spring being anchored to said sleeve.
3. A device as set forth in claim 1 including means whereby the handle may be adjusted and locked at various angular positions in a vertical plane in relation to the head.
4. A device as set forth in claim 1 wherein the means for maintaining the yoke in the plane 5. A device as set forth in claim 1 including spaced bearings within the head for the yoke carried shaft, spaced bearings in said head in which said shaft is rotatably mounted, a rotatable adjustable sleeve within the head between the the rotatable adjustable sleeve.
6. A device as set forth in claim 1 including a rotatably adjustable diamond ferrule carrying plug transversely of the carriage and a diamond ferrule extending transversely through said plug.
