IMPROVEMENT IN EXPANSIBLE WEDGES.
Specification forming part of Lettels Patent N0. 153,009, dated July 14,1874; application filed May 23, 1874.
To all whom it may concern:
Be it known that I, ROBERT NEsBITT, of Franklin,Venan go county, Pennsylvania, have invented a new and useful Improvement in Expansible Wedges, ot' which the following is a specification This invention relates to the construction of wedges for handles of axes, hammers, and similar tools, and consists of a Wedge made in two parts, which are expanded by means of a screw.
In the drawing, Figure l is a side View, showing the wedge as when applied to a handle; Fig. 2 is an edge view of the wedge 5 Fig. 3 is a longitudinal section of Fig. 2, taken on the line :v x; Fig. 4 is a transverse section ot' Fig. 1 at y y.
Similar letters of reference indicate corresponding parts.
This wedge is composed ot twoV tapering pieces, triangular in cross-section, having' the outer edge of each piece serrated to prevent Withdrawal.
A is the principal piece. B is the shorter piece. The longer part A is spear-shaped or pointed, and extends down into the handle, and has a bevel shoulder, O, which receives the small end of the part B. These two parts are made ot'l either cast or Wrought metal, with an interior half-recess in each, which receives the expandingscrew D. The screw D is tapering, and engages with a tapering female screw, cnt between the two parts ot' the wedge, as seen in Fig. l. The screw is driven down into the recess a by means of a screwdriver applied to the nick E of the head I", and the parts A B are spread apart or expanded in the eye of the tool, so that the tool will not become loosened on the handle. In case the handle shrinks, the tool 'is readily made tight by turning the expanding-screw. Gr represents the teeth or points of the edges of the Wedge. As the wedge is expanded these teeth or points penetrate the wood and prevent the Wedge working' out.
This expansible wedge may be applied to all tools andimplements which require a wedge to secure the tool to the handle, and its advantages must be obvious to all.
Having thus described my invention, I claim as new and desire to secure by Letters Patent A wedge constructed substantiall)T as shown and described, that is, composed ot'two pieces, A B, having an interior recess or cavity, a, and one or more serrated edges or points, G, and a tapering expanding-screw, D, substantially as and for the purposes described.
ROBERT NESBITT.
