Letters Patent No. 94,117, dated August 24, 1869.
IMPROVED MACHINE FOR I PU'NCHING- AND SHEARING METAL.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that we, XVILLIAM H. IvENs and W'IL- LIAM E. BROOKE, both of rIrenton, in Mercer county, and State of New Jersey, have invented certain new and useful Improvements in Punching and Shearing- Machines;`and we do herebydeclare .that the following is a full, clear, and exact description thereof, ref'- erence being had to the accompanying drawings through letters of reference marked thereon, forming part of stripper on the same scale as iig. 5.
The same letters indicate corresponding parts in the several tgures. l
The nature of our invention consists- First, in so applying the Ipower, that while themevtion of' the driver is uniform, the motion or travel of the punch or shear shall be slow while cut-ting through the stu", and quick on receding, thus increasing power. when the work is being performed, and speed when no force is required. l
Secondly, in a novel construction and combination 4of the pu ncli-holder with its stripper, adjustable disk,
and die, whereby the punch and die may be rotated, and thus easily adjusted to diderent points across the plate.
Thirdly, in the combination of devices for retaining the stripper in position unt-il the punch is withdrawn, and its means of adjustment to suit different thickness of plates. y
Fourthly, in the general arrangement ofthe operating-mechanism with relation to the punching'alid shearing-heads, whereby shop-rorlmis economized, and the operation ofthe machine rendered less dangerous.
Referring to the drawings- A represents the frame of the machine, which may be cast all in one piece, with solid 'blocks or anvils a, and throat or opening on either side as at l, the 11pper portions c of which are so formed as to constitute guides for the vertically-sliding heads B B', which carry the punch or shears, and these are further surmounted by suitable frame-work (l, to alord journal-bearing for the operating-mechanism.
Motion is communicated to the punching and shearing-heads B B from the driving-wheel kG, which is rotated by any suitable motor in the direction ofthe arrow e ou iig. 1.
The axis of the wheel O is provided with a sleeve, f,
or other suitable clutch, by which it may be thrown in or out of gear with the train of wheels which `give mction to' said punching and shearing-heads.'
On theopposite end of the axis of the wheel'C is a pinion, g, whichgears with a wheel, 71., on the shaft fi, and on the same shaft i is another pinion, k, gearing with the wheel l ou the shaft m, on whichare irlnly keyed two eccentric elliptical wheels -a 1i', which gear with similar wheels p p', hung to revolve iieely around the shaft i, and which have cast upon one side, or otherwise suitably attached to them, cams q q', by the rotation of which the elbow-levers 'r r' are caused to vibrate, and communicate a vertical reciprocating motion to the heads B B through their short arms s s entering slots or mortisest t in'said heads.
These mortises are made of a length equivalent to the amount of motion intended to be communicated to them, greater than the vertical measurement of the arms s s', by which they. are operated, so that when either head B- is desired'to be at rest while the oper-- ating-gear is in motion, the levers fr and fr may vibrate without moving said head, but when it is desired to operate them, or either of them, a key or wedge, u u', is to be inserted in the mortise t or t, for the arm s or s to strike upon, by which means the heads, or either of them, are causedto reciprocate.
The head B is constructed for punching, and is provided at its lower end witha detachable piece, c?, which iits in a dovetail groove laterally across it, and to this laterally-movable piece c is itted another piece, c, which is capable of oscillation around the vertical centre ofthe head. l
' Embracing the head B, on two sides`and-at its top, is a yoke, D, so formed at its lower end as to carry and clamp a disk, E, which is capable of adjustment around its axis, but stationary in relation to the yoke when the machine is in operation. 5
The piece c' is furthermore formed with a groove ou its under side, which spans the head c of the punches which pass through suitable apertures in the disk E, so thatwhen said disk is turned in its bea-ring in the yoke D, to vary the angle of position of? the punches, the grooved piece c' willv be turned at the same time; this. being set to suit the angle at which it is desired to punch the series of holes while the punches aredepressed, and entering their corresponding holes in the female die nf, which is also adjnstably attached to the bed a, so as to be capable of na similar motion around the same-axis.
The punches or male and female dies are rotated together, and when in proper position may be there secured by tightening their respective clamping-screws u" w".
'Ihis yoke D is further provided, at its upper end,
with vertical adjusting-screw a", and a transverse wedge, al", by which its time and distance of motion may be regulated.
The forked elbow-lever c' is pivoted to the upper f part ll of the frame A, on either side at c", and rests on the transverse Wedge lL, its upper end bearings,T against or being prevented from vibrating by Contact with the cam d until the notched portion olf said cam comes against its hooked upper end, at which time also the punches connected with the head B, having been stripped of the metal punched, the upper portion of the head comes in contact with the adjusting-screw a", and lifts the stripper-carrying yoke, so as to admit of the adjustment of the plate for a repetition of the same operation.
The eccentric elliptical wheels n n and p p are so geared with` each other that the greatest amount of leverage is atiorded at the time the punches or shears are cutting through the plate, and at their return inotion, no power being required, the said punches are speedily withdrawn.
The head B' is operated similarly to the head B, but, as represented in the drawing, is provided with a cutter, b', instead of with a punch or punches, which operates iu combination with the stationary cutter b attached to the bed or anvil (t as a shears.
The machine may, however, be constructed as a double-punching or double-shearing one, or for punch# ing on one side and'shearing on the other, as here represented.
Having thus described our invention,
Vhat we claim as new, and vdesire to secure by Letters Patent, is- 1 l. The combination and arrangement of the-eccen tric elliptic gears a n' and p p', and their cams q q', with the elbow-levers fr lr or their equivalents, for operating the punching or shearing-heads B B', substantially as set forth.
and adjustable disk E, of the vstripper D, with the adjustable die w, substantially as specified.
3. The combination of the cam d and retaining-lever o' with the stripper D, provided with suitable adjustments a and a, substantially as set forth.
4. The arrangementof the driving-gears g 71- k land operating-gears 1) p n n', and their cams q q', above and between the cuttingaud punching-heads, substantially as shown and described, for the purpose set forth.
In testimony whereof, we. hereunto subscribe our names, before two subscribing witnesses.
