O. OLSEN. Portable Tool-Rests.
No. 210,957. Patented Dec 17,1878.
minessem wait UNITED STATES PATENT QFFIoE.
OLE OLSEN, OF OHRISTIANIA, NORWAY.
IMPROVEMENT IN PORTABLE TOOL-RESTS.
Specification forming part of Letters Patent No. 210,957, dated December 17, 1878 application filed October 16, 1878.
To all whom it may concern:
Be it known that I, OLE OLSEN, of Christiania, in the county of Aggerhuus and Kingdom of Norway, have invented certain new and useful Improvements in Portable Tool-Rests; I
' portable tool-rests, for the purpose of holding edgc'tools in. their proper posit-ions, so as to obtain the desired bevel during the process of grinding and sharpening them; and my invention consists of the combination, with a clamp having a side openingfor the reception of the tool that is to be ground, of a set-screw for securin g the tool temporarily inposition in the said clamp, and a roller located in bearings on the under side of the said clamp, which roller rotates freely when laid in contact with a revolving grindstone; and by this simple apparatus any unskilled person will be enabled to sharpen and properly bevel edge-tools of any kind equally as well as the most expert person. All that is required to do is to secure the edge-tool within the clamp in a position according to the desired bevelthat is, the tool is placed in the clamp so that its out-- ting-edge shall extend farther out from the side of the clamp in grinding sharp bevels, and farther back in grinding more obtuse ones.
\Vhen the tool. is secured within the clamp, the edge of the tool, as well as the loosely-revolving roller beneath, is held in contact with the rotary grindstone, by which Iobtain a true bevel, no matter how eccentric the grindstone may be.
This invention is equally useful in holding the tool when it is drawn on the oil'stone, or when ground on emery-wheels, &c.
I am aware of Letters Patent granted to 0. Banks, May 31, 1870, No. 103,739, in which a swivel caster-frame is jointed to a slottedframe for holding the tool, which frame is closed on four sides, and I wish to state that I do not claim such an arrangement and construction as my invention.
I make the toolcarrying frame open on one side, as described, so that the tool can be inserted sidewise, by which the edge of the tool is not liable to come in contact with such frame during the act of inserting it therein. The roller is located in hearin gs firmly secured or made in one piece with the tool-holder, by which great accuracy is obtained in grinding the tool. The roller is located in said hearings directly underneath the tool-holder, by which arrangement the roller and the edge of the tool to be ground are brought closer together, so as to enable me to grind tools more accurately, especially if the grindstone is of irregular shape.
On the accompanying drawing, Figure 1 represents a side elevation of my invention; and Fig. 2 represents a central longitudinal section on the line A B, shown in Fig. 1.
Similar letters refer to similar parts when ever they occur on the drawings.
a represents an ordinary planentool, that is inserted within the side opening, b, as shown, which opening is made in the metallic clamp 0. cl is a set-screw for holding the tool, as shown, which set-screw is inserted through the upper forward end of the clamp c. c 0 represent bearings beneath the clamp c, for the looselyrevolving guide-rollerf. 5 represents a portion of the grindstox'xe, as usual.
What I wish to secure by Letters Patent, and claim, is
The herein-described tool-clamp for grinding tools, consisting of the frame 0, with its side opening, 0, for the insertion of the tool in a lateral direction, set-screw d, and stationary bearings e e, for the loosely -rotatin g roller f, all arranged and combined substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own invention I have attired my signature in presence of two witnesses.
OLE OLSEN.
