HAND COMPRESSION TOOL FOR DIES AND CUTTERS Filed July 28, 1945 BY )ZZ/ZL,
Patented Mar. 14, 1944 HAND COMPRESSION TOOL FOR DIES AND CUTTERS Morris Canter, New York, N. Y.
Application July 28, 1943, Serial No. 496,455
2 Claims.
The object of the present invention is to provide a manually operable compression tool for operating cutting blades or dies, including such dies as those employed for collapsing metal seals.
The specific object of the invention is to provide a device of this character which will be powerful in its action, simple in construction, and enable ready disassembly for changing cutters or dies.
The invention will be described with reference to the accompanying drawing, in which:
Figure 1 is a view in elevation, partly broken away, showing the tool in position preliminary to an active stroke, the device holding cutting blades.
Figure 2 is a plan view, partly in section, the section being taken on the line 2-2, Figure 1.
Figure 3 is a view similar to Figure 1, showing the position of the members at the end of a compression stroke.
Figure 4 is a front end elevation of the structure with the parts in the position of Figure 3.
Figure 5 is a perspective view of the movable die or blade holder member and the like which comiects the same with the upper handle member.
Figure 6 is a perspective view of the lower die or blade holder with a blade therein.
Figure '7 is a fragmentary view, in elevation, partly in section, showing a modified form of contact between the upper handle member and the upper die holder in which the upper handle member carries a contacting roller for a cam face of the upper die holder.
Referring to the drawing, it will be seen that the device comprises a lower member i serving as a casing for the operative parts, the lower member being formed with a horizontal arm hr, the said lower member being provided with a vertical aperture at a to receive the headed centering point 2, the latter being engaged by spiral spring 3.
The upper end of the housing I is forked, thus providing two parallel guide plate-like sections Em between which is slidably disposed the compression die holder. The compression die holder is best shown in Figure 5. Being adapted, in said embodiment, for holding the upper two cutting blades, its lower face is channeled to receive a blade 6 and its upper portion is channeled to receive a link pivoted at 8 and, in turn, pivoted in the forked area f of the compression handle 9 which is apertured to receive pivot ill.
The compression die holder carries a short stud or arm II which projects through a vertical aperture formed in the Wall of member I which is adjacent aperture a, and engages the top of centering point 2. The compression die holder also is formed with 2. depending guide arm l2 abutted at opposite sides by the spaced blocks l3 constituting the lower die holder. The latter, in the present embodiment, supports a cutting blade l4. Both blocks i3 and cutting blade M are formed with threaded apertures to receive connecting screws l5, and said lower die holder is held in position in member I by two screws indicated at [6.
The blade 6 in the compression die holder is held in position by screws H, as shown more particula-rly in Figures 1 and 5.
It will be understood that the compression die holder and lower die holder will be modified in accordance with the type of dies required for use.
In the modification, Figure 7, the upper die holder has in its upper channel a hardened steel cam block l8 secured in position by screws I9 to engage a contact roller 20 pivoted on a stud 2| carried between the forks f of the compression handle 9.
The device can be used as a Wire strip and bolt cutter and also for collapsing embossing dies and the like.
It will be seen that the compression die holder is formed with a bar-like guide plunger which projects into a guide aperture provided by the holder for the fixed die or cutter. By this means the compression die holder is firmly guided, both rearwardly and forwardly and at its sides, which is an important feature of the device.
In dies and cutters of usual construction the movable die cutter is guided at its sides and at one other face and there is a tendency for the cutter to shift because it is not held firmly forwardly of the cutting edge. In the present construction the die cannot shift.
Another important feature of the invention is the arrangement of the spring release for the compression die holder by means of a vertical cavity formed in the member l containing the spiral spring acting through a centering point which, in turn, transmits motion to the lateral stud on the compression die holder.
Having described my invention, What I claim and desire to secure by Letters Patent, is as folows:
1. A hand compression tool for dies and cutters comprising a casing and a handle carried thereby, the casing being formed with an internal supporting face and contiguous opposed guiding means affording operative connection between the lever and the movable die-holder, a guide bar depending from the movable diet holder and means carried by the casing and afiording receiving guide faces iorsaid guide bar. V
2'. A hand compression tool for dies and cutters '10 holder and the lever.
constructed in accordance with claim 1, in which 7 the die-holder on .the supporting face consists of two blocks adapted to receive a die between them, screws connecting the blocks, screws extending from the outer face of the casing and into the blocks, the movable die-holder having opposed channelways providing two sets of opposed walls,
one set receiving a die and the second set receivv ing the connection between the movable die- MORRIS CANTER.
