SPECIFICATION forming part of Letters Patent No. 726,288, dated April 28, 1903.

Application filed March 27,1902. Serial No. 100,178. (No model.)

To all whom it may concern:-

Be it known that I, ELI E. l-IENDRIOK, a citizen of the United States, residing at (larbondale, in the county of Lackawanna and State of Pennsylvania, haveinvented a certain new and useful Improvement in Tool-Handles, of which the following is a description.

This invention relates to handles for tools of various sorts--such as files, rasps, &c.-and has for its object the provision of an article which can be cheaply manufactured and which shall be free from the many defects experienced in handles heretofore on the market. Of the latter one form comprises in addition to the handle proper an outwardlyprojecting tenon at one end provided with a ferrule, both said tenon and said ferrule being screw-threaded and said ferrule in some cases being screwed into a recess formed in a shoulder in said handle. This is not only expensivein view of the necessity of providing an annular groove in the handle and screwthreads both on the exterior of the tenon and in the interior of the ferrule, but is unreliable in use, since the ferrule frequently works loose, thereby failing to contribute to the strength of the tenon and handle. In another form heretofore suggested a ferrule is employed which incloses the tenon of the handle and is driven into a shoulder in the latter, said ferrule being of cast metal and the outer end thereof being so thick as to contribute to the support of the tool shank. Among the various objections to structures of this character In ay be mentioned the cost of such ferrules, greater weight of metal being necessary and this being cast, as aforesaid. Again, the tenons upon which such ferrules are placed being necessarily of considerable length, additional means must be employedsuch, for instance, as a pin driven through the ferrule and into the tenon for preventing the parts from working loose during operation, and this in addition increases the expense. In short, all previous structures of which I am aware are expensive as compared with the invention hereinafter described,and in addition to this theylack necessary strength and the parts thereof frequently become loose and separated in practice.

Under the present invention I employ a handle, preferably of wood or other suitable material and provided with a tenon,'which for economy and strength is formed integral with said handle. I also employ a ferrule of metal of uniform diameter, which may be cheaply and expeditiously formed, either by spinning or pressing from sheet metal. One end of this ferrule is closed save for a central orifice of such size as to admit the tool-shank. The other end is open and the metal adjacent to such end is unsharpened.

In one form of the invention the ferrule near its open end is corrugated, and in addition the extreme end may, if desired, be toothed or serrated, so as not only to more easily penetrate into the structure of the bandle, but also to guard against the ferrule turning in such handle during the operation of the tool. I have found that by employing a ferrule the inner or open end of which is unsharpened the liability of splitting the handle is decreased. The ferrule formed as herein described may be readily and by a single operation driven into the tool-handle around the tenon, and the whole structure as thus constituted can be produced at a cost very much below that of any commercially practical toolhandle heretofore on the market.

The invention is illustrated in the accompanying drawings, in which Figure l is a longitudinal section of a toolhandle embodying my invention, and Figs. 2, 3, and 4 are views of the ferrule detached from the handle.

Referring to the drawings, A designates the handle proper, made, preferably, of wood or other suitable material. This is provided at one end with a tenon B, which may, if desired, be formed integral with the portion A and which may also be formed slightly tapering toward its free end to facilitate attachment of the ferrule. The ferrule O is substantially cylindrical-thatis to say, the sides thereof are parallel, or substantially so-and the outer end thereof is closedsave for the central orifice 0, through which the shank of the tool may be inserted. As here shown, the metal of the ferrule O is of uniform thickness throughout. It is formed, as heretofore described, by spinning or pressing from sheet metal. This feature of uniform thickness applies also to the inner open end of the forrule, which, as hereinbefore stated, is preferably unsharpened. If desired, said ferrule, which is substantially longer than the tenon B, may be fluted or corrugated, as at toward its inner end1l. 6., over that portion which when the ferrule is in position is driven into the handle. Also, and whether said ferrule be' plain or corrugated, the inner end may be provided with teeth or serrations 0 In assembling the parts the ferrule is placed over said tenon and driven down upon the same by any suitable means, so that the open end 0 thereof, Whether corrugated or not and Whether provided with the teeth or serrations c or not, shall penetrate into the shoulder 0t of the handle until the closed end of the ferrule comes into contact with the end of the tenon B. This firmly and securely binds the tenon and in use prevents the same and the handle proper from splitting. Moreover, the coaction between the ferrule on one hand and the handle on the other is so intimate and secure as to preclude'said ferrule from either turning or working loose. Where a ferrule is employed which is corrugated or the open end of Which is toothed or serrated, or both, additional provision is made against the turning of the ferrule on the tenon shouldthe latter shrink. The ferrule having been secured,the tool-shank is inserted in the perforation c in the end of the ferrule and driven I into the handle.

If desired, the tenon and handle may during the course of manufacture be provided With a longitudinal orifice somewhat smaller in diameter than the diameter of the toolshank to be subsequently inserted therein. The toolshank may therefore be readily driven home, whereupon the tool will be ready for use.

Considerable experience with tool-handles employing the invention hereinabove described has demonstrated its utility and commercial superiority over all handles heretofore employed, including those to which reference has heretofore been made. Not only is this true, but, as I have heretofore stated, the handle hereinabove described can be constructed and assembled at a relatively trifling cost.

WVhat I claim is- 1. In a tool-handle, the combination with the handle proper, of a tenon, and a metallic ferrule having longitudinal corrugations and coacting with said tenon and handle, substantially as described.

2. In a tool-handle, the combination with the handle proper, of a tenon, and a metallic ferrule having longitudinal corrugations and teeth or serrations and coacting with said tenon and handle, substantially as described.

3. In a tool-handle, the combination with the handle proper having a shoulder, of a tenon, and a metallic ferrule of uniform thickness and smooth interior,one end of said ferrule being closed save for a central orifice to receive a tool-shank, the other end thereof being open and unsharpened and provided with longitudinal corrugations, said open end being adapted to be driven into the shoulder of said handle around said tenon so as to rigidly secure said ferrule in position, substantially as described.

4. In a tool-handle, the combination with the handle proper having a shoulder, of a tenon, and a metallic ferrule of uniform thickness and smooth interior,one end of said ferrule being closed save for a central orifice to receive a tool-shank, the other end thereof being open and unsharpened and provided with corrugations and with teeth or serra tions, said open end being adapted to be driven into the shoulder of said handle around said tenon so as to rigidly secure said forrule in position, substantially as set forth.

This specification signed and witnessed this 21st day of March, 1902.
