To all whom it may concern:

Be it known that I, ARTHUR WILZ'IN, a citi zen of the United States, residing at presentin Clichy, Seine, France, have invented certaln new and useful Improvements 11'1" operating and continuously-operated feed device adapted to advance a sheet of metal or other material to a tool of any kind at points arranged in quincunx order. This feeding device is so arranged as to be able to give such a result by means of a very simple and easily-adjustable mechanism.

This device comprises, as all the other machines of this kind, a carriage to which the sheet is secured and which is capable of being moved along a slide parallel to the front of the machine and movable upon a stationary guiding device directed toward the tool. The

erated in a continuous manner and combined so as-to impart to the carriage along its slide intermittent movements the amplitude of which is equal to the distance which must exist betweenthe centers of the parts of the sheet which are to be acted'upon by the tool and to cause at each end of the stroke of the carriage an advance motion of the movable guide toward the tool to take place and a reversal the direction of motion of the carriage.

This feeding device is represented by way of example in the accompanylng drawings, 1n

' which Figure 1 is a crosssection made according to line A A of Fig. 2. Fig. 2 is a plan, Fig. 3 is a section made according to line B B of This feeding device comprises a carriage a, carrylng one or several grippers a, in which the sheetwhich is to be advanced toward the tool is secured. This carriage or is capable of being moved longitudinally upon a guide 31, secured to the carriers 1), which can slide transversely on f dovetailed slides a, with which the frame of the machine is provided.

The crank d transriage a along 't e guide I). with'the aid of the Geneva move ent shown. At each revolution the crank-pin of crank d engages in one of the'grooves of the radially-grooved wheel lution.

The rack iis capable of being-shifted longitude: nally upon the carriage or to an extent equal i vto half the distance between two successive punchings, so that at each change in the d i I carriage a will be. moved during one-half only of the movement to'transmit rotary motion in one direction or the other from the wheel h, according'as the,

each "longitudinal movement of the carriage concavity in the adjacent arm of said wheel immediately the crank-pin of crank d escapes from the groove in the wheel 71 so as to com letely arrest the movement of the train of w eels which operate the carriage (1 until the crank d engages in the next groove in the Wheel for imparting a fresh movement to said carria e a. The guide 1), upon which carriage a s ides, itself receives at each termination of the course of the latter a transverse movement equal to the distance between the lines of punchings. This movement is imparted to it by the wheel e, provided upon its periphery with Worm-teeth e, gearing at each revolution with a toothed wheel 0 and imparting to the latter an. angular displacement the amplitude of which corresponds to the number and inclination of the teeth a". At the termination of this angular displacement the wheel 0 is provided with recesses w, in which the rim e of wheel 6 enters in order to lockthis wheel 0 and the guide I). As shown, the teeth 6 rotate the wheel 0 through a quarter of a revolution, and the rim 0 then enters a notch between successive quadrants of the wheel 0 and runs in said notch until the wheel 8 makes another complete revolution.

The wheel transmits its motion through a clutch of any kind 'such, for example, as

the clutch p pro vided with grippers-to a shaft q, turning in two bearings supported.

from the frame of the machine, which clutch allows the st ft 9 to be freed from the wheel 0 when it is desired to return the carriers 1), and consequently the guide b, to the original position. The shaft 9 carries at its ends two pinions g, respectively, gearing with two racks secured o the carriers b upon which the guide I) is mounted. The ratio of the gears transmitting the motion from shaft f to shaft 9 is so devised as to cause the teeth a to mesh with the wheel 0 when the carriage has reached the end of its stroke upon the guide I). When this guide I) has come itself to the end of its stroke, its return to its original position is controlled by any suitable mechanical operating device.

The invention is not restricted to the above-described device. I reserve for myself the right to establish the clearance between the carriage and its feeding device by any mechanical means suitable for that purpose. This feeding device can be adapted to all kinds of cutting, stamping, embossing,

punching, and printing machines and the like.
