Specification of Letters Patent.
Patented June 25, 1907.
Application filed March 28. 1906. Serial No. 308,448.
To all whom it may concern:
Be it known that I, JOHN L. OSGOOD, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Imrovement in Tool Handles, of which the following is a specification.
This invention relates to tool handles and more particularly to wooden handles of the sort used for files and other tools having a tapering tang which is driven into a longitudinal bore or hole in the end of the handle to secure the handle on the tool. The tool works loose in the handle from usage and has to be driven farther into the handle from time to time to tighten it, with the result that the handle is sooner or later split and destroyed. The handle is usually provided with a ferrule encircling a reduced neck or portion at the inner or tool end of the handle intended to prevent the splitting of the handle, but as a metal grip is very objectionable, not affording a good hold if smooth and clean and being injurious to the hands if rough and rusty, a short ferrule is used, thus leaving the wooden grip as long as possible. These short ferrules do not adequately prevent the splitting of the handles.
The object of this invention is to provide such handles with strengthening means which will prevent their destruction,without materially increasing the cost of the handles, shortening the wooden grip, or changing the usual appearance of the handle.
In the accompanying drawings: Figure 1 is a side elevation of a tool handle embodying the invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is an end elevation thereof. Fig. 4 is a transverse section thereof in line 44, Fig. 2. Fig. 5 is a fragmentary longitudinal section of a modified construction.
Like letters of reference refer to like parts in the several figures.
A represents a wooden handle for a file or other tobl. The handle may be of the usual shape,that is circular in cross-section and having the enlarged outer end and tapered body, or it may be of any other referred form, but it preferably has the usual short reduced inner end or neck I) provided with the central longitudinal bore or hole 0 to receive the securing tang of the tool.
D represents a metal tube which extends lengthwise into the body of the handle from the inner or tool-attaching end thereof, par-.
allel with the grain of the wood around the tang hole 0. The tube is thin so that it can be readily'pressed or driven into the wood without unduly mashing or spreading the fiber, and is light so that it will not materially add to the weight of the handle, but is strong so that it will not split under the internal pressure due to the expansion of the inclosed wood when the tang is driven into the handle. Preferably the tube extends inwardly to or beyond the inner end of the tang hole, so. that the tang when driven into the handle to the limit will not project beyond the inner end of the tube and cannot possibly expand and cleave the handle beyond the tube. The tube can be forced into place in the handle by pressure with comparative .ease and accuracy by sharpening its inner end and cutting a shallow annular starting or guiding recess in the handle.
A ferrule E surrounds the reduced end or neck of the handle. This ferrule is not required for strength, although it of course adds to the strength of the handle, but being about the same in size, shape and location as the ferrules ordinarily used, it gives the handle the accustomed shape and appearance. This ferrule can be made separate from the tube D, as shown most clearly in Fig. 2, or it can be formed by an integral annular part or flange E of the tube D, as shown in Fig. 5. In the first construction in which the ferrule is separate from the tube D, the tube is preferably provided with an outwardly projecting annular shoulder f which bears against the outer end of the ferrule or an inwardly extending flange g on the outer end thereof to hold the ferrule on the handle. In either construction the ferrule is retained in place I by the tube and as the latter extends far into the handle and has a very secure connection therewith, the ferrule is so securely held in place that it is practically impossible to detach it from the handle.
The handle as "thus constructed has all of the advantages and desirable features of the ordinary wooden, ferrule-tipped handle, it has the same long wooden grip or hand hold, the wooden socket into which the tang of the tool is driven and held in almost identically the same appearance. In addition to these usual requirements, the tube D renders the handle practically indestructible.
I claim as my invention:
1. A tool handle having a hole in one end to receive the tang of a tool, and a metal tube surrounding said tang hole in the body of the handle between said hole and the exterior of the handle and extending continuously from the extreme end of the handle substantially to the inner end of said tang hole, the end portion of the handle being surrounded externally by an exposed metal ferrule part, substantially as set forth.
2. A tool handle having a reduced end and a hole in said end to receive the tang of a tool, a metal tube located in the body of the han dle between said tang-hole and the exterior of the handle and surrounding said tanghole, and an exposed ferrule part surrounding the reduced end of the handle and retained thereon by said tube, substantially as set forth.
3. A tool handle having a reduced end provided with a hole to receive the tang of a tool, a tube located in said reduced end of the handle between said tang-hole and the exterior of the handle, and a ferrule which is of larger diameter than said tube and surrounds said reduced end of the handle and is retained thereon by said tube, substantially as set forth.
4. A tool handle adapted to receive the tang of a tool in one end, a tube located in the tang-receiving portion of the handle to surround the tang when inserted in the handle, and a separate ferrule which surrounds the end of the handle and is retained thereon by said tube, substantially as set forth.
5. A tool handle having an end adapted to receive the tang of a tool, a short ferrule surrounding said end of the handle, and a separate tube extending into said end of the handle and having a flanged outer end which bears against said ferrule to retain the same on the handle, substantially as set forth.
Witness my hand, this 15th day of March,
JOHN L. OSGOOD. WVitnesses:
