COMPOUND METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 434,231, dated August 12, 1890.

Application filed February 13, 1890. Serial No. 340,282. (No model.)

' To all whom it may concern:

Be is known that I, EzRA STILLMAN BAB- COCK, of \Valworth, in the county of Valworth, and in the State of Wisconsin, have invented certain new and useful Improvements in Compound Metal-\Vorking Machines and I do hereby declare that the following isa full, clear, and exact description thereof.

My invention relates to compound metalworking machines; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is a side elevation of my improvedmachine, partly broken away to better illustrate the construction. Fig. 2 is a vertical transverse section on the line 2 2 of Fig. 1. Fig. 3 is a like section on the line 3 3 of Fig. 1, showing also a broken portion of the punch-supporting shell. Fig. 4 is a transverse section on the line 4 4 of Fig. 5. Fig. 5 is a horizontal section on the line 5 5 of Fig. 1, and Fig- 6 is a like section on the line 6 6 of Fig. 1.

My present invention is, in part, an improvement on the device patented to me Feb ruary 14, 1888, and numbered 377,976, and, like that, combines a vise with a punching and shearing machine, but differs from said machine in details of construction, as hereinafter pointed out.

A is the stationary standard of my machine, having a flange a, by which it may be suspended from a bench .when used in a vertical position, and above this flange is the head B, containing one jaw of the vise, the upper part of said head terminating in a vertical face @1.

C is the swinging standard, having a head D, both heads B and D being longitudinally slotted or cut out centrally, as shown at g h, but the head D being open at the top and only rising to the height of the cut-out portion or slot of the head B. As in my prior patent hereinbefore named, the swinging standard 0 is pivoted at 1) between a pair of bearing-straps E E, which are themselves socured to the stationary standard A between the lugs (Z (Z by a bolt 0. The side walls of the two heads B D have opposing V- shapcd concave faces ff, and fitted in the slots 9 h is a sliding head F, which has a V- shaped concave serrated face 1', the said head F having a longitudinal screwthreaded bore f for the reception of one end of a screw G. In my prior patent just named the screw was movable longitudinally and its forward end was secured to the rear end of the sliding head; but in my present device the screw G is formed with a solid collar is, fitting in a seat in the end wall of thehead D, the outer end of the screw from this point and the bore in the said end wall through which it passes being smooth, and there being another collar 10 secured to said smooth end just outside said end wall, so that as now constructed, when said screw G is turned by its bar j or other hand device, the sliding head F screws upon or from the screw (according to which way the latter is being revolved) instead of moving with the said screw longitudinally, as heretofore. Further, in my present device the sliding head F is provided with laterallyprojecting base-flanges n n on each side, which engagewith longitudinal grooves o 0" at the base of the side walls of the slot h in the head D, to prevent said sliding head F from rising from place when it is wholly within the open-topped slot hin the said head D, and the other vertical-faced jaw e of the vise is formed solidly with said head F in my present device, the transverse ends of said vise-jaw e resting on top of the side walls of the head D and projecting beyond. them, all as best shown in Fig. 2.

The base of my machine is formed, as before, with two parallel horizontal arms I and J, the former extending from the standard A and rigidly united at that end by a piece II, having projecting ears 7t 70, said piece and ears being flush with the outer edge of the stationary standard A, so that the device may be placed horizontally of its great-est length on a bench when more convenient to operate it in this position than in the vertical position shown in Fig. 1. The swinging standard 0 projects below the bottom line of the arms I and J, and is bifurcated to receive one end of a link K, pivoted at m to said standard, the other end of said link being pivoted at m to the similarly-bifurcated eccentric-head n of a lever L, which head is in turn pivoted at 29 between the arms I and J.

M is a bell-crank-shaped detent journaled on a shaft or pin g, which extends through the said arms I and J adjacent to the piece II, and when my machine is to be used as a vise the detent M is turned, as shown in Figs. 1 and 6, with the end of the long arm of said bell-crank pressing against the adjacent edge of the swinging standard C; but when the machine is to be used for punching or shearing, then the lower or short arm of the detent is moved and the long arm thrown up and back against the piece H, out of the way of the swinging standard.

The punching device in my present machine is constructed as follows: The upper part of the stationary standard A, just below its head B, is grooved out for the reception of a circular plate N, provided near its circumference with a series of holes 1, t 25 t of different diameters, and below this groove there is secured by screw-bolt u the lower flange r of a supporting-shell O, the upper portion of which is offset, as shown in Figs. 1 and 5, so as to furnish space between its inner surface and that of the standard A for the metal to be punched, said upperportion having two rearward-extendin g wings s 8, having horizontal grooves s s in their upper inner rear surfaces, while the front or inner wall of said shell 0 is provided with aholet' therethrough for the admission of the punch P, which latter is secured by a set-screw w in the stock Q, which in turn is pivoted by a bolt 00 to the standard 0, the end of said stock Q being rounded and fitting within a corresponding recess 0: form ed in said standard, which latter is further out out or recessed, as shown at 00 for the reception of the described upper portion of the shell 0, the rear wings s sof which projectover and rest upon the top edges of the described bearing-straps E E, as best shown in Fig. 4. It is designed to use a series of these punches P corresponding to the diameters of the holes 25 t in the circular plate N, which plate is turned around within its groove to bring the hole 15 of desired diameter opposite the hole 7) in the shell 0 for use in connection with the particular punch P to be used at any time; and for the purpose of steadying the stock Q'and insuring that the punch I shall always be properly guided to place, the said stock Q is provided with trunnions s .9 that tit and move in the described grooves s s in the rear side wings s s of the supportingshell O.

R R represent the shearing-blades of my machine, which are secured by bolts g g within suitable recesses z a formed in the standards A and O, as shown in Fig. 1, the blades in this present case diifering from those in my aforenamed prior patent, in that, whereas they were formerly set with practically Vertical cutting-edges, (in the position of the machine shown in Fig. 1,) they are now formed with inclined opposing cutting-edges nearest together at the top and with the space normally between them increasing regularly from top to bottom, which gives a better out than the former arrangement. As in my said prior patent, all of the parts are operated by the lever L, which brings the swinging standard 0 and its attachments against the stationary standard A, so that the metal being worked can be held in the vise or punched orsheared, as desired, by a single movement of the said lever, while the present construction of the vise enables the upper vertical-faced jaw, which is connected to the swinging standard, to be adjusted, which is a great improvement over the former construction, and at the same time the concave faces of the vise can also be adjusted, and the present construction of the punching device insures better results with greater convenience than formerly.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a compound metal-working machine, the combination of a stationarystandard having a fixed vertical-faced vise-jaw at its upper end, and aswinging standard pivotally connected to the stationary standard and having a vertical-faced vise-jaw at its upper end independently movable relative to its movable supporting-standard, with an operating-lever having an eccentric-head pivoted to the base-frame of the machine and united by a link to the lower end of the said swinging standard, substantially as set forth.

2. In a compound metal-working machine, the combination of a stationary standard having stationary vertical-faced and concavefaced vise-jaws at its upper end and a swinging standard pivotally connected to the sta tionary standard and having vertical-faced and concave-faced vise-jaws at its upper end movable independently of their movable supportingstandard, with an operatinglever having an eccentric-head pivoted to the baseframe of the machine and linked to the lower end of the swinging standard, substantially as set forth.
