Description
Nirnn STATES FFICE@ L. D. wYNKooP, oF o'wAsso, MICHIGAN.
Specification forming part of Letters Patent No. 125250, dated April 5, 1864.
To all whom t may concern:
Be it known that I, L. D. WYNKooP, of Owasso, in the county of Shiawassce and Stateof Michigan, have invented a new and Improved Attachment for Turning-Lathes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side elevation of my invention 5 Fig. 2, a transverse vertical section of the same, taken in the line x x, Fig. 1; Fig. 3, a horizontal section of the same, taken in the line y y, Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to a new and useful attachment for turninglathes, whereby beads and similar ornaments may be turned or formed on sticks or other articles centered in the lathe, the device being self-feeding and capa ble of being applied to any ordinary turninglathe.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A A represent the two heads, and B B the two centers, of an ordinary turning-lathe. These parts, being of ordinary construction, do not require a minute description.
(l represents the bed of the lathe, the same being composed of two parallel bars, a a', connected by crossties b b, to which the heads A A of the lathe are attached.
D is a T-shaped frame, which rests horizontally on the bars a e of the bed C. Through one end of this frame a screw, c, passes vertically, said screw resting on the bar a, and through the ends of the other part of said frame Vertical screws d d pass, the latter being grooved at their lower ends to it on a guide, e, which is secured' to the bar a. (See Fig. 2.) The frame D is allowed to slide freely back and forth on the bed U of the lathe, the grooved screws d d and guide c retaining it in proper position.
To the frame D there is secured an upright, E, in the upper part of which there is fitted horizontally a bearing, F, the interior of which is of cylindrical form the greater por tion. of its length, and through which the stick or article G to be operated upon passes.
This bearing has an aperture, f, made in its under part, and an aperture, g, is also made in said bearing a little at one side of the center of its top to admit of a roughing-off knife, H, passing through it, said knife being of an obtuse V form, as shown in Fig. 1. This knife is held in proper position by a clamp, l1, and set-screw o', as shown in Figs. 1 and 2.
I represents a bar which has an up-anddown movement, and is connected to the upright E on the frame D by guides j j, arranged in any proper way to admit of the free vertical movement of said bar. This bar I is connected by a link, J, with the inner end of a lever, K, which has its fulcrumR on the frame D, and a weight, L, at its outer end. Through the lever K a rod, M, passes vertically, the lower end of which rests upon a pattern, N, secured to the bed G of the lathe. The rod M has a spiral spring, O, upon it, and also a nut, l?, which is tted on a screw cut on the rod, and by turning the nut the rod M may be raised and lowered in the lever K. To the upper end of the bar I there is attached a knife, Q, which is of form, one side being considerably longer than the other. This knife works in the aperture f in the bearing F.
The operation is as follows: The stick G is gotten out of the proper size or dimensions and ceni ered in the lathe as usual, the stick passing through the bearing F, and the bearing being moved or placed close up to the head A of the lathe. The stick G is then rotated, and the frame D is fed or moved along on the bed C by the action of the knives H Q, the cutting-edges of the latter having an oblique position relatively with the stick, and thereby serving to feed themselves along like a nut on a screw. The knife H roughs ottl the stick, while the knife Q has a rising and falling movement imparted to it in consequence of the rod M resting ou the pattern N, which is formed with beads precisely like those designed to be cut or turned on the stick G, and the latter will therefore be cut or turned with beads or ornaments corresponding to those on the pattern.
I do not claim, broadly, a self-feeding or augular knife for turning-lathes, for such have been used for cutting spiral grooves and beads on turned work in a lathe; but,
Having thus described my invention, what I do claim as new, and desire to secure by Let! pattern the outer part of the lever K' rests', ters Patent, is all being arranged to operate substantially' as The bearing F, provided Wit-l1 the knives H and for the purpose herein set forth.
v Q, and attached to a sliding frame D on the y lathe-ned C, in combination Withthe rising L' D' VVYNKOOP' andfalling bar I, to which the knife Q is at- Witnesses: taehed, the loaded lever K, connected to bar ELI D. GREGORY,
I, and the pattern N on the bed C, on which J. B. BARNES.
