F.' A..POTTBR- Tom-HOLDER? No. 77,522. l Patented May 5, 1868.
@uitrit gieten getraut @frn FREDERICK A. POTTER, OF- NORTH PROVIDENCE, ASSIGNOR TO FALES,
JENKS, AND SONS, 0F SMITHFIELD, RHODE ISLAND.
Letters Patent No. "(7,522, dated May 5, 1868.
utrnovsn TOOL-HOLDER.
TO ALL WHOM IT MAY CONOERN:
Be it known that I, FREDERICK A. Potr'run of North Providence, in the county of Providence, and State of Rhode Island, have invented a, new and useful Improvement in Tool-Holders; and I do hereby declare'that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.
Figure 1 is a'vicw of the holder and cutting-tool inperspeetivo.
Figure 2 is n sectional view, through thelinea b.
Figure 3 represents the cutting-tool.
Various means have been contrived for holding an independent cutting-tool in a holder, involving much ingenuity, and attended with proportionate .expense in construction. My improvement'aims attho utmost simplicity of structure, but in point of utility the article which Iproduce is not surpassed by any of the many devices which have preceded it.
A is a rectangular bar of metal, of proper size to fit a tool-post. B is the cutting-tool, which may conveniently be made from a rod of jewellers steel, and needs only to be ground properly at the point to be in the proper form for use. The side of the tool-bar should be furnished with nicks, a, and in form such as would Y result from the use of a tapering round file when applied to cut such. nicks. A hole or 'mortise, in form corresponding with the tool-har, is to be cut through the holder, and at any preferred angle with the axis of the holder, as shown. l l
From side to side, through the holder, and connecting with the hole or mortise which the tool is to occupy, o. plain cylindrical and slightly-tnpering hole is drilled, into which aI pin, b, is to be fitted. The tool-bar is to be so set in the holder that some one of the nicks a upon its side will coincide with the sul-fece of the'hole which the piub is to occupy. The pin is now to be inserted, when the tool will be firmly secured in the holder. The relation which the tool-bar, the pin, and the holder bear to each other, is shownA in section at ig.l2.
I am aware that a tool-bar has been, before my invention, furnished with nicks, and a holding-plate or catch has been used in combination with such tool so nicked, and the holder to aid in holding the cuttingtool.
I do not, therefore, claim broadly such combination; but
What I do claim as my invention, and desire tosecure by Letters Patent, is
The :tx-rangement of the holder A, the tool-bur B, and the holding-pin b, with reference to euch other, substnntially as described for the purposes speoied.
