Skal? 2 @dei ed 5mm @atente @iii weas-aw WILLIAM E. SCOTT AND DANIEL L. WOOD, OF TERRE HAUTE, INDIANA.
Letters Patent No. 86,324, dated January 26,1869.
IMPROVED PUNCHING-MACHINE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
tallic punching-machines can be easily and certainly raised at every backward motion of the hand-lever, thereby superseding the use of springs for that purpose, which at best are unreliable in ,their operation, and liable to become impaired.
To enable others skilled in the art to'make and use our improvement, which is equally applicable to allsized punches, we will proceed to describe the same.
We construct the body of our 'punching-machine in any of the known forms, and use the ordinary eccentric lever for forcing down the punch; but for the pur# pose of securing a perfectly uniform and reliablereverse motion of the punch, we use an L-shaped reciprocating lever, or pallet, which we shall call in this specification by this latter name.
The lower limb of this pivoted pallet engages with the under side of the punch-head, and the upper limb rests against Lhe back of the operating-lever. When the lever is moved backward, it presses upon the upper, while the lower limb elevates the punch. Y
'Corresponding letters in Figs. A and B refer to the same parts'.
Figure A, perspective drawing of our improvement.
Figure B, sectional side view of the working-parts.
e, pallet, pivoted at l;
d, eccentriceoperating lever, pivoted at le;
e, body of the machine;
f, punch;
g, die; and v h, temper-screw, to regulate distance of material being worked.
The dotted lines in Fig. B show the position of the working-parts when the punch is elevated,
By the foregoing references, the operation will be readily understood. y
When the lever cl is raised from an inclined to an upright position, the front eccentric impinges upon the head of the punch, and forces it down with the lower limb of the pallet, while the upper limb follows the bank eccentric of the lever, and when'the lmotion of the lever is reversed, that of the punciiand pallet is reversed also, thus producing a simultaneous reciproeating motion to all the working-parts.
In the construction of our punching-machines, we do not coune ourselves to any special size for the .several parts, or kind of material used, but are governed in that by the size of the machine to which our improvementv is to be. attached, and the power to 'be exerted.
The combination, in punching-machines, of a caniheaded hand-lever, which, moved in one direction, will cause the punch to descend and perforate the metal underneath it, and, when moved in the opposite direction, will,.by. forcing back the e'nd of a secondary lever, causethe said secondary lever to elevate the punch, is not a new -combination, the same being described in the patent granted to F. He'usell, foundpublished in Brevets dliwentlon Belges, volume ix, page 285of Category 5, and we do not claim such combination; but
Arranging the secondary lever, shaped substantially as described, on a fulcrum at a lower elevation 4than that of the primary' or hand-lever, and so that one extremity of the same shall be constantly engaged with the punch, and the other constantly in contact with the eccentric head'of the hand-lever, all substantially as herein set forth.
W. E. SCOTT.
DANIEL L. WOOD.
