To all whom it may concern:
Be it known that I, FRANK GOODNOW, of Albion, in the county of Orleans and State of New York, have invented certain Improvements in Plane-Handles, of which the following is a specification:
My invention consists in the combination of a plane-handle with devices which render it readily attachable and detachable to the plane, so that one handle may be used on any number of planes.
In the accompanying drawing, which is a perspective view, A is a handle of any ordinary form. B is a strap, which is secured to it by means of screws or otherwise, and is provided with the dowels a and b, and also a support at C, for the slotted cap-plate D. The slotted cap-plate D has its fulcrum at c, and is provided with a cam-shaped projection, d. E is a screw, which passes loosely through the slotted cap-plate D into the strap B. On this screw a short lever, F, is placed, which is provided with a cam, which engage with the cam-shaped projection d on the slotted cap-plate D. Two holes, e e, are made in the end of the plane G, corresponding with the dowels a and b. A screw is placed in the top of the plane at f in such a position as to engage with the slotted cap-plate D, which is slotted to receive it.
The handle, having been previously fitted to the plane, is attached to it by passing the dowels into the holes in the end of the plane, and at the same time passing the slotted end of the slotted cap-plate D under the screw f The lever F is now turned; this depresses the end of the slotted cap-plate D, and consequently raises the slotted end, causing it to bear with sufficient force against the under side of the head of the screw f to hold the handle firmly to the plane.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is —
The combination of the handle A, strap B, provided with the support C and dowels a b, slotted cap-plate D, provided with a cam-shaped projection upon its rear end, cam-lever F, and plane G, provided with holes e e, constructed substantially as shown and described.
FRANK GOODNOW.
