SPECIFICATION forming part of .Letters Patent No. 277,882, dated May 22, 1883.
.Application Bled March 19, 1883. (No model.)
To all whom t may concern.-
. Be it kuown that I, JOHN I. CARR, a citizen of the United States, residing at Chicago, in the count-y ofCook and State of Illinois, have invented certain new and usefulImprovements in Tool-Holders for Grindstones, of which the following, in connection with the accompanying drawings, is a specification.
In the drawings, Figurel is a side view of ro a tool-holder embodying my invention.
2 is a top or plan view ofthe same. Fig. 3 is a section in the plane ofthe line war of Fig. 1, and Fig.'4 is an end view ol the base of the tool-holder. 4Like letters of reference indicate like parts.
A represents the gridstone,and B its supporting-frame.
C is the base of the tool-holder. This base has a at or horizontal part, a, and a vertical 2o orupright part, a', and in the top of the part a is a deep groove, a.
D is a curved arm, the lower part of which is' horizontal and enters the groove a, and a is a lgroove in the horizontal part of the said arm. El is a set-screw or binder passing through the upright part a and into the groove c". The screw E performs the function of holding the arm D lirmly at a greater or less distance from the perimeter ot' the stone A,
l 3o the said arm being adjustable in the groove a. The upper part ofthe arm D is vertical, as shown.
F is a cylindrical bar or rod, passing freely through the upper end ofthe arm D; and Gr is a plate or small table, cast on the rod' F, and
located near one end thereof.
G is a vertical flange, cast onthe plate G; and H is a set-screw passing through the Bange G.
I is a plate pivoted to the plate G, and I is a bridge-piece or arch extending from side to side of the said plate'.
J is a set-screw passing vertically through the arch I.
K is the knife or blade of a carpenters plane.
L is a washer, and L' a nut on one end of the rod F.
' M is a handle, which may hc applied either to the rod F or to the plate G.
Fig.
'lo use this holder for the purpose for which it is intended, Ifsecure the base C of the toolholder to the frame B, locating the said base at one side of the stone A, as shown in Figs, 1 and 2. The rod F, by passing freely through the upper end of the arm D, is .capable of being rotatedtherein. I pass the knife or tool K underneath the bridge-piece I, bringing the edge to be sharpened `against the stone, tilt' ing the plate G by rotating the rod F until the tool is presented at such an inclination to the stone as to produce the proper or desired bevel on the groundedge of the tool. I then tighten the tool in its place by turning down the screw .I. In some casest-he tool may have a cuttingedge which is diagonal or at an angle with relation to its lateral edges. In such cases I turn the plate I on its pivot until the tool is .presentedat the proper angle to produce the diagonal edge desired, and set the screw H againstthe edge of the'plate I, so as to hold the tool properly in place for being ground or sharpened. To examine the cuttingfedge of the tool from time to time, I tilt it up by means ofthe handle M. Also, by means of the said handle, I am enabled to lnove the tool back and forth laterally across the perimeter of the stone by sliding the rod F laterally in its bearing or seat. The tool may also be moved or rocked slightly from side to side while being ground, so as to make the cuttingedge ofthe tool slightly rounding, as is frequently the case in jack-planes. To do this the screw H should be left loose, and thc plate I turned slightly iu both directions on its pivot. The washer L and nut L', though not absolutely essential, prevent the rod F from being drawn entirely out of the arm D in one direction, and the plate G in the other. By locating the plate G on one end ofthe rod F the base C may be placed at the side of the stone.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Thel combination of the base C, having therein the groove a", the sliding arm D, the screw E, lthe rotary and laterally-movable rod F, passing freely through the upper end of the arm D, and having on one end thereof the plate so,Y
or table G, with its flange G', the seid rod and table being made in one and the same piece, the arched or bridged plate I, pivoted to the plate G, and' the screws H and J, substantially 5 as and foi1 the purposes specified.
2. The combination, in atool-holder for griudstones, of the rotary and laterally-movable rod F, having east ou one end thereof the plate G, v
with its flange G', the arched or bridged plate I, pivoted to the plate G, and the screws H 1o and J, substantially as and forl the purposes specified.
