Leners Patent No. 91,064, and June s, 1869./
MPROVEMENT IN TOOL-HANDLES.
To all whom tt ma/y concern Be it known that I, EDGAR J cnn Arnon, of the city, county, and State of New York, have invented a new and useful Improvement in Handles for Files and other Tools; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a longitudinal section ofa toolhandle constructed according to my improvement, and
Figure 2, a similar view ofthe same', illustrated, with the tang of the tool inserted therein.
Similar letters of reference. indicate corresponding parts in both figures.
The object of this invention is to provide more durable, and, in other respects, better handles for files, screw-drivers, and other tools, than the wooden handles commonly employed; and to this end,
The invention consists in a handle'co'mposed of a hollow shell of castfiron, or other metal, fitted with a plug, for the reception of the tang of the tile or other tool, such plug being protected by the metal shell, and being retained therein by a suitable construction of the interior of the shell.
In order that others may understand the construction and operation of my invention, I will proceed to describe `it with reference to the drawings. Y A is a hollow shell, of circular or oval form in its transverse section, and-of the s'arne outward form as the ordinary handle, and is constructed of cast-iron or other metal. i
This hollow shell A has provided upon its inner snrfnce, and about midway of its cavity, an inwardly-projecting abutment or stop, b; and also within the entrance of thecavity, a shoulder, a.
Within this cavity, and between the stop b and shoulder a, is lodged a plug, B, intended to receive the tang of the tool.
This plug B is provided centrally and longitudinallyl with a cylindrical taper hole, c, for reception and guidance of the tang.
The portion ofthe shell A containing the plug B is or may be constructed of greater thickness than other parts of the said shell, thereby the better to resist the necessary strain consequent upon the expanding of the plug when the tang is being forcibly driven thereiu. Ribs, or other inwardly-projecting corrugations, may be provided upon the inner surface of that por tion of the shell containing the plug B, for the purpose of more securely confining said plug within its placeV in the shell.
The plug B, having been constructed of the desired form and proportion, is inserted into the open end of the shell A, so that its inner extremity rests against, and is stopped by the abutment or stop b.
The forcible entrance of the tang of a ile or other tool into the cylindrical hole c, will now so expand the plug B as to drive its periphery against the inner surface of the shell A, and the outer portion or edge of its outer' extremity behind the shoulder @thereby securely wedging and locking the said plug within its place inthe shell. I
Theresistance ol'ered by the unyielding sides of the shell, prevents further expansion of the plug, which not only provides against the splitting of the plug, but also increases the resistance of the same to the further entrance ofthe tang. This resistance to the entrance of the tang, increases the tenacity with which it is retained within the plug when driven to itsY place therein.
By this means a handle is provided that will last longer,'is not liable to split, and 'will not roughen upon its surface by the consequent wear and tear of age and hard usage.
One or more holes may be provided in the shell cf Y, the handle, behind the plug B, for the purpose of allowing a circulation of air through it.
In the handles of soldering-irons, and other tools which have to be heated, these holes willfbe of great advantage, as the circulation of air through them will tend to keep the handle cool.
What I here claim, and desire to have secured by Letters Patent, is#- v The arrangement of the stop b and collar a, on'the interior of a hollow metal handle,for retaining the plug B, in the manner substantially as shown and described.
