VILLIAM II. IVENS AND WILLIAM E. BROOKE, 0F TRENTON, NEW JERSEY.

IMPROVEMENT IN COMBINED PUNCHING AND SHEARING MACHINES. l

Specification forming part of Letters Patent No. 114,297, dated May 2, 1871.

To all whom it may concern Be it known that we, WILLIAM H. IvENs and WILLIAM E. BROOKE, both of Trenton, in Mercer county, and State of New Jersey, have invented certain new and useful Improvements in Combined Punching and Shearing Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, lreference being had to the accompanying drawing through letters of reference marked thereon, forming part of this specification, and in which- Figure 1 represents a rear elevation of a machine embracing our improvements 5 Fig. 2, a vertical transverse section taken on the line x on Fig. 1, Fig. 3, a vertical longitudinal section of the upper part ofthe same, taken on the line z z on Fig. 2. Fig. 4. is a transverse section, showing a modification of the link-connection on the same line as in Fig. 2. Fig. 5 :is a face view of the male and female clutch. Fig. 6 is afront view of theshear and its curvilinear adjusting key or wedge.

The same letters denote corresponding parts in the several figures.

Our present invention is an improvement upon thatpatentedto us on the 24th of August, A. D. 1869, and numbered 94,117 5 and it consists in providing for the free rotation of the axles or driving-shafts within the eccentric gears, and a novel construction of clutch to insure their engagement'when in position to dispense their greatest power on the resistance offered to the cutter or punch; also, in the means of adjustment of the cutter or punch head to adapt it for operating onvarious thicknesses of metal, and in a novel arrangement in one machine of upper or punching heads and dies and a lower shearing device. Furthermore, it embraces a novel means of adj ustin g the inclination of the upper or movin g shear; also, a novel arrangement of foot-levers, links, springs, and clutch-yokes, so as to place the operation of each machine or part thereof under control of one person, and each part independent of the other.

Referring' to the drawing, A represents the main frame of our machine, having punching or riveting heads at either side for operation alternately or separately, and beneath these is a peculiarlyformed shearin g-table, B, which will be more fully described hereinafter. C is the main driving-shaft, which receives its 1no tion through a band or gear wheel, D, from any suitable motor. On one end of the shaft is an eccentric elliptic gear, E, which gears with a similar one, El E2, arranged on opposite sides of it. The two latter are connected with sleeves Fl F2, and rotate freely around the shafts .G1 G2, and when it is ydesired to rotate said shafts or either of them the clutch H1 or H2, or both, being in .spline gear with their respective shafts, are slid into gear with the sleeve or sleeves. These clutches and sleeves, which are more clearly represented in Fig. 5, are of the ordinary form, with the exception that the one is formed with a web, a,

extending from jaw to jaw on one side of the,

axis, and the other has the jaw cut away next to the axis on one side, as at a', to receive the web a, which insures the engagement of the eccentric gear when in the proper relative position to that of the eccentric b on their axis, so as to obtain the greatest leverage of said gear during the cutting or punching action of the head.

The clutch-levers c are operated to keep the clutches in gear with the sleeves F1 or F2 by levers d1d2, which are actuated by treadles c1 e2, through the Arock-shafts j f2 and their cranks and wrists g g2. These treadles are arranged in such position that the operator can work them with his foot without disengaging either hand from the material to be operated on and the clutches are disengaged by the action of the springs h1 h2 against the upper ends of the levers d1d2, respectively, immediately on removing the foot from the treadle. I

The heads l1 l2 are caused to reciprocate in vertical guides -Kl K2 by therotation of the shaft or shafts GL G2, on which are eccentric formations b for operating said heads through the pitmen l1 Z2, connected with said eccentrics b and links Z3 L4, connected with shafts m2 and m4, attached to the heads, on which latter shafts are also eccentrics a3 and n4. Said shafts Grl an d G2 and m2m4 each carry a worm-wheel ,p3 and p4, between which is arranged a worm, g2, gearing with both of them, so that by the rotation of the latter double the scope of adjustmentis afforded to the sa-id heads or shears, or, with under pressure.

The shearing-cutter r is connected with the head I2 in a detachable manner by means of a link, s, fitted to said head and to the cutterstem t by dovetails, or in any other suitable manner, so that by the removal or insertion of said link s the head maybe used forpunching purposes, or to communicate motion to the shearing-cutter r.

The cutter r is made adjustable on its stein Y by means of a wedge, u, the upper or back edge of which is curved and rests against a correspondingly-curved bearing, o, so that by the adjustment of this wedge the angle of inclination of the cutter may be varied to suit the thickness of metal to be severed. This wedge may be fitted with a worm-gear or a simple slot and set-screw, as represented in Fig. 6, by which it may be adjusted to the desired angle.

w is the stationary cutter, against or in com# bination with which the cutter r operates to shear the plate, and is rigidly attached to the frame of the machine. rlhis part of the frame of the machine is of peculiar formation, as represented in Figs. 1 and 2, being somewhat of an S shape, and gradually increasing in thickness as it extends beyond or away from the cutters, and by which a table, as at B2, supports the overhanging weight of the sheet being cnt, and the part severed is depressed and passes underneath the part B2, which entirely prevents the choking of the shears, no matter how thick the sheet of metal may be, if the shears are capable of cutting it.

What is here claimed as new, and desired to be secured by Letters Patent, is-

- l. The combination and arrangement of the three elliptic gears E El E2, shafts G1 G2, clutches H1 H2, eccentrics b, links l, and heads Il I2, substantially as set forth.

2. The clutch F2, constructed with a web, a, on one part, and cavity a on the other part, for operation, in combination with the eccentric elliptic gears El or E2, to insure the interlocking of the clutch with said gears 'when in position specified, for the purpose set forth.

3. The combination of the links Z3 Z4, eccentric-shafts ml'm, worm-wheels p3 p4, and worin g3 with the head Il, for adjusting the elevation of the latter, substantially as specied.

4. The frame A B, of the form and construc-Y tion substantially as set forth.

5. Jointly with the frame A B, the head or heads I1 I2, lower shearing-jaws t w, and links s, for the purpose set forth.

6. The wedge u, made curvilinear on its upper edge, in combination with the cutter r and its plunger t, for Varyin g the angle of said cutter, essentially as set forth.

7. The arrangement of the foot-levers e1 or e2, rock-shafts f1 f2, springs h1 h2, clutch-yokes c1 c2, and levers di d2 on either side of a double machine, so that the operation of the one side is rendered independent of the other, substantially as shown and described.

In -testimony whereof we have hereunto subscribed our names this 8th day of September, 1870.
