ISAAC Gannon POLO, lLLiNois, AssIGNOR TOv HIMSELF `AND WILLIAM GREGORY, OF SAME PLACE.
Leiters Patent No. 93,194, dated Augztst 3, 1869.
IMPROVEMENT IN TINNERS BENDING-MACHINE.
To all whom it may concern:
Be it known that I, ISAAC GRIM, of Polo, in the county of Ogle, in thev State of Illinois, have invented a new and improved Tinners Bending-Machine; and I do hereby' declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.
This invent-ion relates to improvements in machines for bending the edges of square sheet-metal pans for wiring them, and the object is to provide a simple and cheap machine adapted for pans of various sizes.
Figure l represents a plan view of my improved machine, with a part broken out, showing the jaws partly turned, as when the bending-operation is being performed.
Figure 2 represents a transverse sectional elevation of the'same.
Similar letters 0f reference indicate corresponding parte.
A represents a forming-block or bar, suitably sup-- ported between the end supports B. Itis provided with 'deep notobes,'0, near the ends, for the admissionv of the two sides of the pan at right angles from that side which is to be bent, to admit the latter-to be presented to the griping and bending-jaws D E, the former of which is supported on journals, F at each end, and provided with a handle, G, pivoted to it at ]:[,'a'nd arranged to afford a means of turning the jaws over the former for bending the sheet. The several notches are intended for pans-'of various sizes'.
The jaw E lies upon the face of the jaw D, and is provided with a right-angled ange, I, lapping behind the broad rear edge of the said jaw D.
This flange is provided with slots K,varranged be moved longitudinally on the other to open apd v close, the inclined slot-s K and studs 'L causing it to rise or ialL'according to the direction -in which it is moved.
N represents a gauge, arranged between the jaws, having a handle, O, projecting through a slot in the ange I, for moving it. It is caused to move to or from the edges of the jaws b'y inclined grooves and pins, shown in dotted lines at P, when moved longitudinally by the handle O.
The side of the'pan to be bent is engaged with the jaws to the depth required, the inner -face of the said side resting upon the upper face ofthe former, and the jaws, after clamping the edge of the said side, are turned'over the former, to eiectthe bending in a manner common to such machines-and, in this case, by
the same lever which effects the clamping of the jaws together.
Having thus described my invention,
What I claim as new, and desire to secure by Letters Patent, is-
The lever G, link M, ange I, slots K, studs L,
jaws D and E, gauge N, handle O, former A, having teeth C at each end, and the end" supports B, all constructed, arranged, and operating as hereinshown and described, for the purpose speciie ISAAC GRIM. I
