IMPROVEMENT IN TOOL-HOLDERS.
Specification forming part of Letters Patent No. 132,240, dated October 15, 1872.
To all whom it may concern:
Be it known that I, ALFRED BELcHAMBER, of Ripley, in the county of Brown and State of Ohio, have invented a new and useful Improvement in Tool-Holder,'of which the following is a specification:
This invention relates to a device for facilitating the. grinding of plane-bits and chisels on grindstones and consists in a holder and fulcrum-stand arranged in combination with the grindstone, as hereinafter described.
In the accompanying drawing, Figure 1 is a sectional side view of a grindstone, showing my tool-holder as when in use, the section being on the line a: m of Fig. 2. Fig. 2 is a top view.
Similar letters of reference indicate correspondin g parts. 4
A is the grindstone. B is the grindstoneframe. 0 is a stand of iron in the staple form, adjustably attached to the grindstoneframe by means of screw-nuts, or in any manner, so that-the same can be raised and lowered or properly adjusted to the stone. The cross-bar of this stand forms a fulcrum for the tool-holder, which is made to operate upon the principle of the lever. D is a metallic band, of rectangular form, the bottom of which is preferably made a little concave to prevent the slipping of the tool which rests thereon.-
E represents the tool. F is a bar or handle rigidly attached to the top of the band D. The forward end of this bar forms a hook, G,
T by means of which it is removably connected the tool is held fast in the holder. The edge of the tool thus fastened in the holder becomes the point of resistance, While the power or weight is applied to the rear end of the bar, which power may be more or less, as may be required.
With this holder the plane-bit or chisel can be ground with a true bevel, and much more accurately than it can in the ordinary way, and the bevel maybe varied and made long or short by varying the position of the tool back or forward in the holder or fulcrum'stand, either vertically or laterally. The holder is readily removed from the stone, and the tool handle or bar F, and screw H, substantially as and for the purposes described.
2. In combination with a tool-holder, the'adjustable fulcrum-stand O, as and for the purposes described.
3. The tool-holder and adjustable stand, in combination with a grindstone, constructed and arranged to operate substantially as shown and described.
