TOOL-HOLDER.
SPECIFICATION forming part of Letters Patent No. 274,344, dated March 20, 1883,
Application filed December 4, 1882. (ModeL) the hands, the said holder being constructed and arranged as hereinafter fully described.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similarlettersof reference indicate corresponding parts in all the figures.
Figure l is a side elevation of a grindstone with my improved tool-holder represented in side elevation on the right hand as when adjusted for holding a gouge, and in sectional elevation on the lefthand as when adjusted for holding a chisel. Fig. 2 is a plan view of the grindstone and holder, the said holder bein g adjusted for grinding a tool of which the edge is oblique to the longitudinal axis of the tool. Fig. 3 is a longitudinal sectional elevation of the tool-holder, and Fig. 4 is a sectional elevation of a portion of the said holder.-
0n the end of the bench a of the stone b, I mount a suitably long and strong flat bar, 0, for the base-plate of the holder, in aclip, d, in which it may be shifted lengthwise and toward and from the stone, and be secured at any desired point by a screw, 6, said clip being pivoted on a rod,f, allowing the upper end of the base-plate to rise and fall, as desired, and on which the base-plate may be shifted forward and backward to cause the tool to traverse the face of the stone.
At the upper end of the base-plate o ther is a short plate, g, connected to it by a pivotbolt, h, by which said plate 9 maybe screwed fast to hold it in any required fixed position; or it may be allowed to swing when the nut of the pivot-bolt is slack, said plate g being bolted at its upper end to the upper end of the base- ..plate, and having a clip, a, near its lower end,
in whichan extension, j, of the bottom plate, 7.5, of a tool'clamping box is fitted to slide toward and from the stone and be fastened at any point by a set-screw, Z. The sides at of (1 assumes the plane of the upper surface of the tool, and bears fair on it whether parallelwi'th the bottom of the box or not. The said pivoted arrangement of said bar also allows the screws to be turned up to clamp the tool in the upright position, or thereabout, as represented in the right hand of Fig. l, as for grinding a gouge, the plate 95 being in this case screwed back against the tool, clamping it to the plate a. In this case the pivot-bolt It will be slackened to allow the box to be swung forward and backward on the said pivot to make the required round shape of the point.
A spring-bar, n, is attached to the clip d to apply the requisite elastic pressure of the tool against the face of the stone by means of a weighted lever, 10, pivoted to the bench near the floor, to which lever said lever a is connected by a cord, at, passing over a guide, y, and being connected to lever to by belayingpins 2, whereon it may be readily shifted to alter the length, as may be required, for shifting the tool-holder higher or lower on the stone, as is required, for making the bevels of the edges of the tools more or less blunt. The weight a. on the lever 10 is adjustable along itfor varying the force of the pressure of the tool. on the stone. 7
In case it is desired to grind circular edges on planebits and the like, the plate 0 is to be shifted up or down, and plate j shifted t6 set pivot h in the axis of the circle to be ground, and said pivot slackened so that the holder may be swung forward and backward across the face of the stone by the extension 3', thereby presenting successively all the points of the curve for grinding.
The stone maybe provided with a holder on both of its faces, if desired, for enabling two 4 tools to be ground at once, which may be at IOO 1. In a tool-holder, the clip d, screw 6, and pivot-rod f, combined with the base-plate c in the manner described, so that said plate may be shifted lengthwise in the clip, rise and fall with it, and move back and forth with the tool, as described.
2. The combinatiom'with a base-plate, 0, adjustable lengthwise and movable laterally and eircumferentially on a pivot,f, of a tool-holder pivoted to said base-plate for vibration transversely to the face of the stone, substantially as described.
3. The combination, with a base-plate, 0, ad-
justable lengthwise and movable laterally and circumferentially on a pivot, f, of atool-holder pivoted to said base-plate for vibration trans-- and the clamping-plate q, said clamping devices being arranged with relation to the sides at of the box for clamping tools thereon in the vertical or nearly vertical position, as set forth.
6. The combination, with a tool-holding box, k m, pivotally and adjustably attached to the base-plate c, of the pivoted clamping-bar n, clamping-screws p, and clamping-plate q, substantially as described. I
7. The combination, in a tool-holder for grindstones, of the base-plate c, plateg, pivoted to said base-plate, and the tool-holding box is m, and clamping devices, said box being adjustable on the plate 9 by clip t and extension j, substantially as described.
8. The combination, in a tool -h-older for grindstones, of the base-plate 0, adjustable lengthwise and movable laterally and circumferentially on a pivot, f, and the spring-bar u, and weighted pressurelever to, said base-plate 0 having a tool-holding attachment, substantially as described.
