SHEAR MACHINE.
Application filed November This invention relates to shear machines, and particularly to that type which is adapted to cut a sheet of metal into irregular shapes, such as circles and the like.
The object of my invention is to provide a shear machine of simple, durable and inexpensive construction in which the cutters may be easily and quickly attached or removed.
A further object is to provide a shear of this class so constructed and arranged that the sheets of metal may be more easily and rea'diiy fed to the machine.
A furtl i'er object is to provide in a shear 13 machine of the class above described, im-
proved means for adjusting the cutters relative to each other.
A further object is to provide improved means for imparting movement to the shears.
My invention consists in the construction, arrangement and combination of the various parts'of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in whichi Figure 1 is an end elevation of my improved shear machine.
Figure a side elevation of the same.
Figure 3 is a detail sectional View taken on the line 3-3 of Figure 2. I
Figure 4 is a detail sectional view taken on theline 4l4 of-Figure 3.
My improved'maehine comprises a base upon which is mounted an upright support 11. The upper end of the support 11 terminates in a substantially horizontal semi-circular supporting plate 12. One half of the diametrical edge of said plate is provided with an upwardly extending portion 13 which terminates in an inclined bearing member 14. The said bearing member 1 1 is substantially parallel with and vertically above the opposite one-half of the diametrical edge of the plate 12. The inner end of the bearing member 14 terminates at a point near the vertical center of the circular plate 12, the bearing member 14 being provided with an upwardly extending portion 15 having at its upper end a horizontal bearing member 16. The bearing member 14 is designed to rotatively receive a shaft 17, the inner end of which is provided with a rotary cutter 18 having its periphery beveled, as clearly shown in Figures 2 and 4. The said 30, 1925. Serial No. 72,377.
cutter I8 is detachably secured thereto by means of a nut 19, the outer end of the shaft 17 being provided with a beveled gear 20 designed to mesh with a pinion 21 carried by a shaft 22, rotatively mounted in the bearing 16'; The shaft 22 is provided with a hand wheel 28 which provides means whereby the said shaft 22 may be rotated.
The support 11 is provided with a lug 24 in which is rotatively mounted a stud bolt 25 having its outer end provided with a pivot portion 26. which is formed somewhat; smalier than the portion 25 and slightly eccentric therewith. Pivotal'ly mounted on the member 2G is a bearing member 27 which is inclined upwardly and inwardly, said hearing being below the horizontal face of the plate 12 with its inner end terminating near the center of said plate. The said bearing member 27 is designed to rotatively receive a shaft 28 having at its inner end a rotary cutter the inner edge of which is designed to coa'ct with the inner edge of the cutter 18-. The said cutter 29 is detach-ab y secured to the shaft 28 by means of a nut 30. The shaft 17 lies in a, vertical plane common with the diametrical edge of the plate 12, while the shaft 28 lies in a vertical plane which intersects the first said plane at the vertical center of the plate 12 in the usual manner.
It will be-noted that the bearing member 27 is pivotally mounted on the member 26 which is eccentric with the member This provides means whereby the inner face of the cutter 29 may be adjusted toward and from the inner face of the cutter 18 simply by loosening the nut 31 on the outer end of the member 6, which will permit the member 25 to be rotated, together with the incur ber 26, causing the bearing member 27 to move longitudinally and the cutters adjusted toward or from each other.
For adjusting the cutter 29 laterally, i have provided a. set screw 32 which is mounted in a suitable lug 33 on the upright 11, said set screw being designed to engage the under surface of the inner end of the hearing 27. By this arrangement it will be seen that the cutters 18 and 21 may always be maintained in proper relation relative to each other, whereby a clean cut may be made, and at the same time minimize the power necessary to operate the machine.
The top and under surfaces of the plate 12 are of helical formation. The top surface loo 47- be compactly arranged.
extends upwardly and terminates in the upright 13, while the lower surface extends downwardly and terminates in the support 11. The under surface of one-half of the diametrical edge of the plate 12 is substantially in alinemeut with the upper surface of ihe other half of said diametrical edge, so that a plate to be cut may be caused to engage the cutters 18 and 29 in such a manner that one portion of the plate, after it has been cut, will be supported by the upper surface of the plate 12, while the other portion will engage the under surface of said plate and be turned downwardly, inasmuch as the plate may be turned in a horizontal plane.
The cutter may be caused to out either straight or irregular cuts or circles if so desired.
Thus it will be seen that I have provided a shearing machine of simple, durable and inexpensive construction, in which the stock supporting plate 12 is formed semicircular in plane rather than circular as heretofore has been the practice, with the means for supporting the cutter members 18 and 29 in substantially the same cutting relation relative to each other and to the plate, as has heretofore been the practice.
It will be seen in Figure 2 that the shafts for mounting said cutters extend in substantially opposite directions from each other instead of one of the shafts being substantially above the other. By this arrangement- I have provided means whereby either of the cutters 18 and 29 may be removed without removing the other one, while with the machines now in commercial use it is necessary to first remove the lower cutter before removing the upper one.
It will further be seen that by arranging the shafts so they extend in opposite directions, considerably more room is providec for handling the plates to be out, and provides means whereby the driving gears may Means for easily and quickly adjusting the cutters relative to each other has also been provided.
I claim as my invention:
1. A shear machine comprising a support, a horizontal semicircular stool upno plate having its upper and under .1. formed slightly helical with the diaine rical edge of said plate lying in a substai'ith-illy horizontal plane, an inclined shaft supported substantially parallel to and above onehalf of the diametrical edge of said plate, a second shaft supported substantially parallel to and above the other one-half of the diametrical edge of said plate, means for 1m parting longitudinal movement to said second shaft, said means comprising a bolt pivotally mounted in said support having an cccentricportion at one one, means for pivotally mounting the outer end of said shaft to said eccentric portion, means for adjusting the inner end of said second shaft toward and from the inner end of the first said shaft, and a cutter member detachably secured to the inner end of each of said shafts. I
2. A shear machine comprising a support, a semi-circular stock supporting plate, an inclined shaft supported substantially parallel to and above half of the diametrical edge of said plate, a second shaft supported substantially parallel to and above the other half of the diametrical edge of said plate,
a bearing member for supporting the secondv one of said shafts, means for imparting longitudinal movement to said bearing member, said means comprising a bolt pivot-ally mounted in said support having an ecccn tric portion at one end, said eccentric portion being pivotally mounted in said bearing, and means for adjusting the free end of said bearing laterally, a cutter member detachably secured to the inner end of each of said shafts, said cutter members being supported in operative relation with each other.
