- FLEXIBLE FILE.
Speciiication of Letters Patent.
Patented Aug. 3.3, 1907.
To all whom 'it may concern: Be it known that I, HARRY E. HARKIN, of the city, county, and S'tate of New York, have inventedcertain new and usei'ul Improvements in Flexible Files, of` which the following is a specification.
This invention relates to an improvementin flexible to produce a iile capable oiA accomodating itself to curved and irregular surfaces. By nay invention l acl complisli this result and also the further result of being able to replace worn portions of the filing surface andl thus prevent the entire loss of the le. I propose to make the filing surface in suitable short sections and then thread them upon aV support preferably ilexible. These sections may be made of any suitable shape and when threaded upon a iiexible support should preferablyhave their adjacent edges beveled to allow a greater ilexibility of the tile.
My invention will be readily understood from the accompanying drawing, oi which Y Figure lis a plan View, Fig. 2 a lateral elevation, Fig. 3 a side view of one of the sections, Fig. 4 a top view oi the saine, Fig.l5 an end view oi the same, and Fig. 6' an elevation showing a modified formt In iny drawings, A represents short sections oi suitable length having a filing surface, B the support preierably flexible, C springs at the end of the support for holding the sections 1A A in contact, F handles at thev ends of thele, D tranverse slots through the sectionsl and E the beveled edges of the same.
The construction and operation'is apparent from the drawing. vI thread upon the support preferably flexiheld in contact with each other by springs C, C, abutting against the handles F, F, lattached in any suitable vway to the supports.
evidently are that the iile can reach places ordinarily ble the desired number of short sections which may be practically inaccessible and can file considerable irregulai-'surfaces at once. And further, ii part of the file is worn, a sufficient number oi sections can be replaced.-
What I claim as my invention and desire to secure by Letters Patent is l v l. A iile comprising a series of transversely slotted substantially rectangular shaped sections each havingbeveled edges, a flexible support extending through said slots, a
handle at each end of the'support, and spring means forv positively maintaining the abutlnent of said sections.
2. A le comprising a series of transversely slotted suhstantially rectangular shaped sections each having beveled' vedges, a iiexible support extending through s'aid slots, la
handle at each end of the support, and spring, means mounted upon the support :1nd interposed between each end section of the series and each handle for positively maintaining the abutment of said sections. In testimony whereof I havesigned this specification in the presence of two subscribing witnesses.
