JOHN C. SHACKLETON, OF LAVRENCE, MASSACHUSETTS.
Letters Patent No. 66,641, dated July 9, 1867.
IMPROVED LATHE-TOOL.
flilgc gcl ctule refimt to in tlgrsc ittttets {intent nut mating part at rigs same.
'lO ALE WHOM I'l MAY'GONCERN:
Be it known that I, JOHN C.v SHACKLETON, of Lawrence, in the county of Essex, and State of Massachusetts, have invented a new and improved Lathe-Tool and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to malt-e and use the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to the manner in which a turning-tool for lathes in'iron-turning'is constructed and secured to the shank or t0olhol(ler. And it consists in forming the shank with a head in such a manner that the cutting tool is firmly secured to it and made adjustahle by screws, as will he described.
Figure 1 represents the tool-holder with adouhle cutter attached, showing the under side of the head and cutter.
Figure 2 is a side view of the some, showing the screws which holdthe cutter.
Figure 3 shows a side view of the cutter detached. I
Figure 4 shows a top view of a cutt erfdetaehed.
Similar letters in the figures oi' the drawings indicate like parts.
A represents the tool-holder or head, with the shank, which is attached to the slide rest of the lathe in the usual manner. B is the shank. C represents the cutters. The head A has a double slot in its end something like an inverted T, or the bottom of the slot is enlarged laterally, as seen at a in the drawing. This form of slot extends through the head. The tool as it stands in the lathe is seen in fig. Z. t will he seen that the upper portion or edge of the cutter 1) projects forward as iron-trimming tools usually do, and that the slot through the head A is made hevelling so that the cutter is thrown in that position when it is placed in the head. The hevelled or projecting portion is seen in the'inverted tool, fig. 1. The cutters are fitted to this slot and .slipped' into it when used, as-seen in figs. 1 and 2. The side of the cutter hassinall conical recesses or countersinks, as seen in fig. 3 at d; These recesses are for the ends or points of the screws 2, by which the cutter is held in place. A number of these countersinksis made to allowoi' the cutters being raised as they are ground off on the top while-in use. The lugs ur'projections on the sides of the cutter at a, which fit into the side grooves of the slot in the head, hold the .cutterfirmly to the head, while the screws prevent it from slipping down. Cuttersof various kinds may he fitted to the head for various kinds of work. This arrangement is especially adapted towels for cutting and chasii'ig-screws of various ltinds in a lathe, and it will be found very useful in most'kinds of lathe-work.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
I claim the combination of the tool-holder A B, tool C, and set-screws e, when constructed andarranged as herein set forth.
