EMERY CLOTH FILE.

Specification of Letters Patent.
Application filed August 30, 1909.
Patented May 24, 1910.
Serial No. 515,228.
To all whom it may concern:
Be it known that I, EDWARD GANZ, a citizen of the Empire of Germany, residing in New York, in the borough of Queens, county of Queens, and State of New York, have invented certain new and useful Improvements in Emery-Cloth Files, of which the following is a specification.
This invention relates to files, and more particularly to emery-cloth files, and has for its object to provide means for supporting an emery-cloth or similar and suitable material so as to form a file, wherein the emerycloth may be quickly and conveniently applied and stretched in position in such a manner as to be quickly and conveniently renewed when worn by use.
The nature of the invention consists of an emery-cloth file comprising two hinged sections adapted to hold a strip of emery-cloth in a certain position and tightly stretch it in position by the actuation of the sections.
The invention consists more particularly of an emery-cloth file the frame of which is formed of two main sections hinged at one end, each section being composed of fixed and movable pieces, the fixed piece being provided with a beveled portion adapted to be engaged by a movable locking piece, the emery-cloth being applied to the frame when in its open position by being gripped by the locking pieces, and stretched over the frame on the closing of the same.
In the accompanying drawings, forming part of this specification, Figure 1 represents a perspective view of one embodiment of my invention, shown in position for use, Fig. 2 is a top-view of a file, drawn on a larger scale, Fig. 3 is a side-elevation of Fig. 2, and Fig. 4 is a perspective view of the frame of the file, showing the same in extended position in full lines, in which position it is adapted to receive the emerycloth and lock the ends of it in position, and in dotted lines, whereby the frame is shown in closed position and the emery-cloth as stretched over the frame.
Similar reference characters indicate corresponding parts throughout the several views.
Referring to the drawings, my improved emery-cloth file consists of two main sections hinged together at one end over which passes an emery-cloth, the ends of which are secured to the main sections, the free ends of which main sections are shaped to form handles.
The main sections 10 are composed of two strips 11 and 12 which overlap each other for some distance and are connected by rivets 13. The main sections are connected at one end by a strap-hinge 14 by means of which the opening and closing of the main sections, as shown in Fig. 4, is possible. The free ends of the main sections are formed into handles and are provided with swinging locking pieces 16, pivoted at 22, which are rounded off so as to conform to the shape of the handle, and beveled at 23 and slightly inclined at their free ends so as to enter a corresponding beveled edge 24 of the overlapping strips of the main section 10, as shown in Fig. 3. A strip of emerycloth 19, of equal width with the main section of the file and of sufiicient length to extend at either side of the file from the hinged end to some distance beyond the beveled edge 24, substantially as shown in Fig. 4, is provided. This strip is intended to be locked in position between the beveled portions 23 and 24 by the swinging into clamping position of the pivoted pieces 16, whereby the emery-cloth is rigidly secured at its ends. The emery-cloth is applied to the main sections when in their open position, as shown in Fig. 4, then clamped as described between the main sections and the pivoted pieces, whereupon the hinged main sections or members are brought together in the position shown in Fig. 3, or in dotted lines in Fig. 4, by means of which the emery-cloth is slightly stretched so as to arrange itself tightly over the frame, whereby it is arranged in very efiicient operative position. If by use the emery-cloth should become lax, by a stretching of the same, it can then be resetto take up the slack and be arranged in tightposition.
The improved file enables a mechanic to replace in a very quick and convenient manner the strip of emery-cloth when the one in use is worn out, which may be done by simply cutting a strip to the proper width and then applying the same in the manner described.
One embodiment of my invention has been shown, but I do not wish to be understood to limit myself to the details of the same,
since changes may be made therein without departing from the spiritand underlying principle of my invention.
1. In an emery cloth file having two sections hinged at one of their ends, fastening means near the free ends of the sections for detachably securing both ends of a piece of emery cloth passing over the hinged ends of the sections to the sections when the sections are in open position, and holding the said cloth in position when closing the sections.
2. In an emery cloth file having two main sections hinged together at their inner ends and having an emery strip passing over the hinged ends, locking pieces at the free ends of the sections for clamping the ends of the emery strip to the sections.
3. An emery-cloth file consisting of two hinged main sections having an emery-strip passing over the same, each formed of an overlapping and underlapplng extensionportion riveted together, and locking strips pivoted to the outer ends of the extension portion and adapted at their inner edges to lock the ends of the emery-strip.
4. An emery-cloth file consisting of two main sections hinged together at their inner ends having an emery-strip passing over the same, and each having inwardly beveled and laterally inclined parts, and pivoted locking strips beveled and laterally inclined at their free ends.
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses EDIVARD GA NZ.
