To all whom', t may concer/vt:

Be it known that I, SAMUEL WIOKS, a citizen of the United States, residing atCleveland,in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Means for Recutting Files; and I do declarethat the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in means for recutting files by electrolytic action, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure I is a vertical sectional elevation of my improved apparatus, showing a series of iiles in the bath and presumably subjected to a current. Fig. 2 is a perspective elevation of an end section of the apparatus, showing certain details thereof, as hereinafter fully described.

A represents a suitable tank which is provided with aoid-proof lining ct of lead or the like, and is adapted to receive the acid solution or electrolyte. It may be of any preferred size and adapted to any size of files.

In the operation the files I5 which are to be resharpened become the anodes by connecting with the positive pole of an electric battery or other source of electricity-say such as shown in diagram in the drawings-and the rods C of carbon or the like, which are shown here as partially pocketed in the wall of the tank, become the cathodes by connecting them with the negative pole of the source of the current.

The electrolyte within the tank normally has a feeble and slow action upon iron and steel, except when under the influence of an electric current, when it then becomes more rapid and caustic. The particular elements of this electrolyte may vary according to circumstances, and they may be composed of either acids or alkalies.

The preferred electrolyte is sulfuric acid, which may be more or less diluted with water.

As many of the rods or cathodes C as may be desired can be used, and there may be as many as there are files, more or fewer, and all are pocketed in the wall of the tank after `perforated lead shield c incloses them.

the manner shown especially in Fig. 2, and a The resistance and the consequent chemical action to cut all the files uniformly is more or less governed by the number of rods used, the pocketng of the same also contributing to this end.

, The shields c provide protection for the files and prevent any possibility of the files and rods C from coming into contact through accident, overcrowding, or otherwise.

The cathodes C are all suspended from a metallic or other suitable conducting-frame D, which in this case consists of rods supported by posts d or their equivalent on the tank and having the elements C suspended therefrom in electrical connection. The wire 2 from the generator E passes to this frame, while the opposite wire 3 goes to the several anodes or liles B. The said elements or files B are shown here as suspended by a spring'- p'ressed clamp 4 from an insulating rod or bar 5, which is secured at its ends to the frame F, erected upon the tank and adapted to carry the switch mechanism for the files, a separate switch G being used for each file and supported upon the horizontal bar f of the frame F. The switch Gconsists of two contact members g and g, iixed, respectively, to the bar F and Yto the metallic strip f', which runs alongon the top of said bar and to which the wire 3 from the generator is attached. The upper member of the switch Gr, therefore, is clamped on the said strip f', while the lower member is attached to the wooden or other like non-conducting-barf,and a switch proper, 6, having a finger extension to control it, is rotatably secured to the lower member in this case and adapted to contact with the upper member when turned on to establish the current through the file. Connection is made by a wire 7 between the switch and the clamp 4, which suspends the file, so that through these several parts a complete circuit is established and connection upon the iile in the solution is edected.

Each Elle has its own switch, and the support 5 for the files is provided with a clamp 8 at its ends, adapting it to be adj ustably attached to the bar j", so that it can be raised or lowered, according to the length of the file to IOO be treated. The clamps 4 are provided with hooks to engage the rods 5 and are easily detached when necessary.

What I claim isl. In an apparatus for recutting iles electrically, means to support the tiles singly and separately, means to adj ust said iiles to any depth desired in the electrolyte, cathode members supported and suspended Within pockets in the Walls of said apparatus, and electrical connections for said files and cathode members, substantially as described.

2. An electrolyte-tank having pockets in its Walls, perforated shields about said pool;- ets, cathode members supported and suspended within said pockets, adjustable means to support and suspend tiles in line Within said tank, and electrical connections for said cathode members and les, substantially as described.

3. An electrolyte-receptacle for recutting files electrically having pockets in its Walls and shields c open tothe electrolyte aboutsaid pockets, cathode members suspended Within said pockets and electrically connected to the negative pole of a source of electricity, in combin ation with a supporting-frame for the tiles vertically adjustable, and electrical connections for the files leading from the negative pole of the source of electricity, substantially as described.

4. In an apparatus for recutting files electrically, an adjustable non-conducting support for the iles, whereby they may be raised or lowered in the bath according to size, a clamp for each file on said support, a separate switch for each tile and an extensible connection therefrom to the said clamp, substantially as described.

5. The liquid-receptacle and the electrodes in the Wall thereof, in combination with a frame across the receptacle and a conducting-strip along the top thereof, an adjustable file-support on said frame, a two-part switch having one part fixed to said frame and the other part engaged on said conducting-strip, and an extensible electrical connection from the switch to the file-support, substantially as described.

Witness my hand to the foregoing specification this 24th day of June, 1899.
