CUTTING PRESS hpplicationfiled April 30,
The; present invention relates to improvements in hand presses for converting ordinary manual pressure on the handle to enormous pressure at the working points ofthe mechanism.
An object of this invention is to provide an improved cutting-press suitable for cutting-dies for cutting up sheet material such as leather, cloth, or paper into all sorts of 0 shapes. 7
Another object of this invention is to pro-. vi de a cutter-carrier which is pivotal ly mounted to swing in a horizontal plane from a noncutting position into alignment with the plunger, and in providing yielding means for maintaining the alignment of the cutter-carrier and the plunger and for centering the cutter and plunger.
Another object of this invention is to pro- 0 vide a fixed vertical shaft in spaced relation adjacent to the upright wall of the frame and on which the cutter-carrier is designed to pivot, the said shaft having a fixed upper collar and a slidable lower collar, and a coil spring intermediate the lower collar and the base plate of the hand press, the said cuttercarrier being mounted between the two collars and being supported jointly with the cutter in an elevated position above the work supporting surface due to the upward pressure of the spring.
Another object of this invention is to cause said mechanism to cooperate so that when the operator uses one handto move the handle and causes the plunger to move up and down, the cutter-carrier and cutter will automatically follow the movements of the plunger, and the operator may use his other hand for shifting the material being cut up.
Another object of this invention is to'form the cutter-carrier of two relatively rotatable members, a rear member pivoted to the vertical shaft and having a fixed pivot shaft projecting radially therefrom, and a front member pivotally mounted on said radial shaft and comprising cutter-gripping means, thus making it possible to reverse the cutter-gripping means and the cutter for expelling the cut blanks from the cutter.
Another object of this invention isto pro- 1932. SerialNo. comes.
vide a hand press having cutter-gripping means which willquickly accommodate various styles of hollow cutting-diesfor working at high speed.
Another object of this invention residesyinwfi the provision of an improvement of this-nature which will be'simple in construction, inexpensive to manufacture, strong and durable.
With the above and other objects in-view the invention will be hereinafter more par- 6 ticularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out inthe claims which form part of this specification.
Reference will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, in which:
Figure 1 is a side elevation of my improved cutting-press in operatin nposition. 570 Figure 2 is a sectiona view,ztaken:as on line 22 in Figure 1, and shows the cutter or cutting-die in operating position intengagement with the plunger and a dot-anddash View of the cutter-carrier and cutterfi7 swung out of operating position andout of engagement with the plunger and reversed for removing the cut blanks from the cutter. Figure'3 is an enlarged sectional view of-a modified guide-sleeve for facilitating the B reciprocating motion of the cutter carrier and shows a spring pressed pull-pin for locking the cutter-carrier in operatingposition.
In'the illustrated 'embodimentrof the invention, the several views show a cutting-" press 10, comprising an open-side frame having a 'T-shape'd upright wall 11, aplunger- "housing 12,depending from an overhanging to rotate the shaft 18, and cause the plunger 15, to reciprocate in the plunger-housing 12.
A shaft 24 is fixed in the upper wall 13, and the base-plate 14, adjacent the upright wall 11, and in spaced relation and parallel with the plunger housing 12. It will thus be noted that the plunger-housing 12, and the plunger 15', overhang the base-plate 14. A collar 25, is fixedly mounted at the upper portion of the shaft 24, and a collar member 26, having an integral elongated sleeve portion is slidably mounted at the lower portion of the shaft 24. An open coil spring 27, is also mounted on said shaft intermediate the lower collar member 26, and the base-plate 14. A
"cutter-carrier 28, is slidably mounted on the shaft 24, between the two collar members and 'is resiliently-supported in an elevated position due to the upward pressure of the coil spring 27. The cutter-carrier 28, comprises a rear member 29, rotatably and slidably mounted on the shaft 24, and is provided with a fixed pivot pin 30, projecting radially therefrom; the'cutter-carrier also comprises a front member 31, pivotally mounted on said radial pivot pin and having arms 32, 33,
-mounted on pivot pins 34, 34, and pressed apart by a flat spring 35, and brought into close relation by means of a wing nut 36, and

grip the cylindrical handle cutting-die 40.
a bolt 37. The arms 32, 33, are each provided with V- shaped jaws 38, 38, designed to 39, of a cutter or An upwardly projecting spring 41, has been fastened tothe rear member 29, of the cutter-carrier 28, and engages with a notch '42, in thefixed upper collar 25, the said notch being positioned in longitudinal alignment with the cutter-carrier and plunger, as shown in Figure. 1, and serves to align thefplung'er W/Vhen the lever 23, is operated, itcauses the .cutting die 40, to cut through the material 7 g '45, and the cutting edge of the cutting die' 'entersinto the upper surface of the-backing material 46. I The operator then repeatedly shifts the backing material and the material ates the actuating mechanism for the cutting- 1 die with the other hand.
As shown in Figure 3, a spring actuated 'pull-p1n member 43, has been provided in the front member 31, of the cutter-carrier 28,
and engages with the pivot pin 30, and serves to lock the front member of the cutter-carrier and the cutting-die in operating posi tion. 'VVhen the cutting-die gets filled with cut blanks, the pull-pin member 43, is pulled upwardly out of contact with the pivot pin 30, and the cutter-carrier 28, and the cutter 40, are swung out of operating position and are reversed, as best shown in dot-and-dash lines in Figure 2, when the cut blanks are removed from the cutter. The cutter is then reversed and swung back into operating position in'contact with the plunger and an other piece of material is cut up. Figure 3, also shows an elongated guide sleeve 44, fixed in the rear member 29,"of the cutter-carrier 28, and which serves to facilitate the reciprocating motion of the cutter-carrier. The use of the guide sleeve 44, may dispense with the collar member 26.
Work for which my cutting-press isadapted, such as the cutting up of layers of material into blanks of any'desired shape hasgenerally been done by hand, the cutting-die being driven through the material by a mallet. As a surface for the cutting edge of the cutting die to strike on, there is usually provided a stationary block 'of wood. Under such conditions, the workman holds the mallet in one hand andthe cutter in the other hand, the material to be cut up being stationary. The workman repeatedly-carries the mallet and cutter to successive portions 7 of the material layingostationary on the block.
It is to be noted that the workman operating my cutting-press stands at the end of the machine where the cutting is done, andcshifts the backing material and the materialto be cut with one hand, while actuating the fixedly aligned cutting-die with the other hand.
It is also to be noted that while I have shown theplunger of my cutting-press as operated by hand by means of a lever, that I may operate the plunger by foot power or by motive power such asby an electric motor and by means of intermittent actuating mechanism.
While I have illustrated my cutting-press as utilizing a tool member for performing a cutting action, it is obvious that I may employ tools which will perform other functions. I do not therefore limit myself to the style of tool shown in the drawing, as I contemplate in connection with my cutting-press the manufacture of quite a number of tools, each of which is to be designed for performing a different function, but all being interchangeable and adapted to the structural" principles of my cutting-press.
r c It is also to be noted that under all modes to be cut up with one hand, while he operof actuating of my cutting-press, the cutting die or cutter is resiliently supported in an elevated position above the work-supporting surface and independent of the plunger andscribed comprising an open-side frame hav-' ing an upright wall an over-hanging plunger-housing a plunger and a flat base-plate, a fixed shaft positioned in spaced relation adjacent to said upright wall, said shaft having a fixed upper collar and a slidable lower collar member and a coil spring intermediate the lower collar member and the base-plate, a cutter-carrier mounted between the two collars for upright reciprocation and being supported jointly with a cutter in an elevated position due to the upward pressure of the coil spring, spring means for aligning said plunger and cutter and an eccentric for actuating said plunger; said cutter being constrained by said aligning and elevating means to follow the movements of said plunger.
2. A cutting-press comprising a frame having a fixed overhanging plunger-housing, a plunger and a base-plate, a shaft positioned in spaced relation and parallel with said fixed plunger-housing, a cutter-carrier mounted for reciprocation on said shaft and being supported jointly with a cutter in an elevated position and extending below said plunger, means for aligning saidplunger and cutter, and means for actuating said plunger, said cutter being constrained by said aligning and elevating means to follow the movements of said plunger.
3. In a cutting-press,-a cutter-carriercomprising a rear member rotataby and slidably mounted on a vertical shaft and having a radially projecting pivot, a front member mounted on said radial pivot and having means for gripping a cutter, resilient means for supporting said cutter-carrier and cutter in an elevated position and means for locking said front and rear members of the cutter-carrier when said cutter is in cutting position.
