UNITED sTATEs PATENT oEEToE.
FRED C. EHINGER, OF PALMYRA, MICHIGAN.
HANDLE FOR TOOLS OR THE LIKE.
maant.
Application filed May 29, 1915.
" all whom 'it may concern.'
Pie it known that I, FRED C. EHINGER, a itizen of the United States of America, reiding at Palmyra, in the county of Lenaree and State of Michigan, have invented ertain new and useful Improvements in Iandles for Tools or the like, of which the ollowing is a specification, reference being -ad therein to the accompanying drawings.
My invention relates to handles for tools r the like, and resides in the novel connecion between the ferrule and the handle -roper, and further in the novel method of ttaching the ferrule to the handle proper.
In the drawings,-Figu1e 1 is a perspecive view of the handle embodying the inention; Fig. 2 is a central, longitudinal ross-section therethrough; Figs. 3 and 4 are ide elevations of the handle proper and the errule respectively; and Figs. 5 and 6 illusrate the manner of assembling the parts.
In handles for tools or the like, it is not nly desirable to have the ferrule so connectd to the handle as to prevent the ferrule rom working loose, but it is also necessary, or a practical handle, that the ferrule preent splitting of the handle neck When the ing of the tool is driven into the end of ie handle. With my invention the ferrule firmly attached to the handle proper gainst disengagement, and also there is proided a suitable reinforcement for the neck f the' handle, which tends to prevent splitng thereof.
Generally speaking, my improved method insists in forming the handle proper with a ead of compressible, expansible material, ad forming the ferrule with a nonexpansile socket which is of larger cross-section ian the cross-section of the band of the arrule that fits the neck of the handle roper, and then forcing the head into enf igement with the socket. During the enigexnent the head of the handle will be impressed, but Vwhen it passes into engageent with the socket it will be expanded. herefore, after the ferrule is in place upon ,e handle it will be tightly secured thereto.
Referring to the structure shown in the .-awings, A designates the body of the hane proper, C the neck thereof and D is `e ferrule. The ferrule D preferably is rmed of a seamless metal structure having band portion E for fitting the neck of the mdle and provided with a socket portion of greater cross-section than the cross- Specication of Letters Patent.
Patented July 25, 1916.

section of the band at the junction between the latter and the socket. Preferably the neck portion of the handle tapers toward the head, while the head has a transverselyrounded. periphery. This spherical-like head provides a tapering face H, the purpose of which will more fully hereinafter appear. The socket of the ferrule is of a configuration similar to the configuration of the head and the handle proper, except the end is provided with an aperture I to permit the tang of the tool to be driven i-nto the handle.
Preferably the neck portion is formed of 'sufficiently less cross-section than the body portion, to place the outer faces of the body portion and the ferrule at the junction thereof in the same plane. This provides a-shoulder J against which the end of the ferrule tightly abuts when the parts are assembled.
The ferrule D is formed of comparatively heavy gage metal and therefore is non-expanslble, but the head which is solid, is made of compressible, expansible material-preferably by making the handle proper of soft wood, asfor instance basswood.
To assemble the parts the ferrule is forced onto the handle proper, and during this engagement the face HA coperates with the tapering band to compress the head sufiiciently to allow `it ,to pass through the smaller end of the band portion of the ferrule into engagement with the socket F. When the head of the handle proper passes into engagement with the socket portion it expands and fills, or substantially fills the socket portion. As the socket portion, at its junction with the band, flares outwardlyrather abruptly, when once the head has passed into engagement with the socket portion it will be retained therein. When the tang of the tool, such as a le, is driven into the inner end of the handle it will tend to further increase the size of the head, thereby more securely lodging' the ferrule in place.
Preferably the end of the handle proper is provided with a bore for receiving the tang of the tool, but the head is not split and to this extent may be considered solid.
While I have shown and described an exceedingly desirable form of the invention, I do not-wish to limit the protection to the Aparticular structure shown, nor to the exact method described.
What I claim as my invention is 1. In a handle for tools or the like, the combination of a handle proper having a tapering neck portion anu naving a head at the small end of the tapering neck portion of greater diameter than the latter at the junction between the head and the neck, said head having a transversely-rounded periphefral portion, and a Seamless. ferrule formed of comparatively heavy gage met-al whereby the ferrule 1s non-expansible, said ferrule being provided with a tapering band portion fitting the tapering neck of the handle proper and having an enlarged Isocket portion of greater diameter than the band at the unction bet-Ween the latter and the socket,'said socket being shaped to fit the head and having an opening inits forward V tools', comprising forming a handle proper l'with a. neck portion terminating at its inner end in an enlarged solid head of compressible expansible material and forming a seamless non-expansible ferrule having a band portion of a size to fit the neck portion of the handle p'roper,and having a socket portion at one end thereof of a size to fit the i head, said socket being of considerably ,Y greater diameter than the band at the junction between the latter and the socket, and
in-then assembling the ferrule and handle by forcing the head through the band portion Vinto engagement with the enlarged socket,
the head being compressed by said band portion during the forcing operation and expanding at the completion of said operation.
3. The method of forming handles for tools, comprising forming a handle proper with a tapering neck portion terminating at its inner end inan enlarged solid head of compressible expansible material and forming afseamless, non-expansible ferrule Ahaving a tapering band portion of a size to fit the neck portion ofthe handle proper, and havin ya socket portion at one end thereof of a size to fit the head, said socket being of considerably greater diameter than theV band at the junction between the latter and the socket, and in then assembling the ferrule and handle by forcing the head through the band portion into engagement with the enlarged socket, said head being'compressed by said band portion during the forcing operation and expanding at thecornpletion of said operation.-
