MACHINE FOR TUB-NING- IRREGULAR FORMS.

Specification of Letters Patent No. 9,822, dated Tune 28, 1853.

T0 all whom z5 may concern.'

Be it known that RICHARD IVARD, late of Naugatuck, in the county of New Haven and State of Connecticut, deceased, on whose estate I, LAUREN VARD, of said Naugatuck, am administrator, did in his lifetime invent a new and useful Improvement in Machinery for Planing Irregular Shapes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, which make a part of this speciication, in which- Figure l is a perspective view of the whole machine, showing most of the operating parts in their appropriate positions when the carriage is brought to the front end of the machine, ready for another set. Fig. 2 is a plan view of the apparatus for setting the material, so as to cut the several sections, showing the collet which raises the front end of the inner part of the carriage beyond the action, or operation, of the jointed levers, the ratchet wheel, ratchet, and the crooked and jointed lever which works them to set the material, and the crank which operates the jointed levers, by means of which'the front end of the carriage is raised, or depressed, to suit the form of the article desired to be formed.

The improvement consists in the use of the jointed levers, suspended from a bar, or trame, above, and the crank by which the levers are operated to elevate and depress the front end of the inner part of the carriage to the desired extent for planing the article in an elliptic shape of polygon, and in the use of the notched collet on the front, or toothed, center, connected with the ratchet wheel, which by means of the curved bar raises the front end of the inner part of the carriage still higher, and more suddenly, than the operation of the levers would do, at the proper time, to give form to a more prominent part of the article, as the square part of a spoke.

The frame, A, A., &c., is made of posts and bars in any of the usual ways, of woo/d or iron. On the upper bars are fitted ways, C, and C, for the carriage, D, D, to slide on to feed the material to the cutting apparatus, all as seen in Fig. l. This carriage, I), D, receives a longitudinal motion from end to end of the material by means of a crank, E, any jointed connecting rod, or pitman, F, F, which receives its motion from the wheel, G, being revolved by an endless screw, or worm, a, on the shaft, B, which, by means of the pulley, I-I, and band, I, is revolved by the pulley, K, on the main shaft, L, which is driven by a pulley, M, and band, or by a crank, or any other ordinary means. The connecting rod, F, F, is attached to the Jfront end of the carriage by the bar, F1. This carriage is made double, so that while the part, N, N, slides horizontally on the ways, t-he part, O, O, may be elevated, or depressed, at the front end, by the operation of the jointed levers, hereafter described.

In the back end of the carriage there must be an adjustable dead center, o, and in the front end a center with a flat, or toothed point, c. This front center is firmly secured in the wooden collet, d, and the ratchet wheel, c, and is turned by means of the ratchet, f, acted on by the crooked and jointed lever, g, g, all as represented in Figs. l, and 2. This lever, g, g, is worked by the inclined planes P, and I?, Fig. l, when necessary, to set the material for cutting another section.

The cutters are made and arranged in any of the ordinary ways for revolving cutters, gouged shaped, or otherwise, and suitably attached to the periphery of the cutter wheel, as shown at Q., Fig. l, and has no longitudinal, nor vibratory motion. This cutter wheel is revolved by the band, R, working on the pulleys, S, and L, by means of the main shaft L, as seen in Fig. l.

Then one longitudinal section has been planed by the carriage having been moved, horizontally, its whole length, over the cutter wheel, (by the operation of the crank C, and the jointed connecting rod, F, F,) the lower end, g', of the lever g, g, is carried outward by one of the inclined planes, l?, and I), which forces the top of the upright lever, z', over to the right, by which means the ratchet, y, is caused to revolve the ratchet wheel, e, one tooth, or division, and thus set the material ready to plane another longitudinal section, and so on until all the sections have been planed, so that the polygon is complete.

To give the elliptic form, or shape to the polygon, a crank, or arm, is attached to the front end of the iiat or toothed center, c, in

sov

front of the ratchet wheel, e which by the revolving` of the ratchet wheel (and the center, 0,) operates the bar, or connecting rod, le, the end of which is attached to the bar, Z, by a joint pin, my. The two ends of this bar, Z, are attached to the central parts of the jointed levers, n, and n, while the upper ends ot the jointed levers are attached to the bar, o, of the trame above, all as represented in Fig. l, and a part shown in Fig. 2. When the crank, y', is carried to the extreme right, (at which nearly, it is represented in Fig. l) or the extreme left, the central parts of the jointed levers, n and n, will be bent out of a vertical position, so as essentially to shorten them, and as their upper ends are held stationary by the joint pins in the upper bar, 0, the pins at the lower ends, (working in the slots,) will elevate the straps, p, and p, which are attached to the front end of the inner part, O, O, of the carriage, and will therefore elevate that end, and with it the toothed center, e, as represented in Fig. 1, and when the crank, j, is in a vertical position, as shown in Fig. 2, (or the opposite) the jointed levers will also be in a vertical position, and therefore straight, so as to depress the front end of the inner part, O, O, of the carriage, and center, c. The crank, j, is adjustable, as to its length, by means of a slot, and is held in its required position by means or" a set screw, as shown in Fig. 2, so that the article may be planed more, or less, eccentric as may be desired.

The back end of the inner part, O, O, of the carriage is attached to the outer part, N, N, by the joint pins, g, g, which serve as fulcrums. These pins may be passed into either of the several holes, so as to elevate the inner end of the dead center, Z), more, or less, as that end of the article is desired to be more, or less, eccentric, and should it be desired to plane an article equally eccentric throughout its whole length, similar jointed levers may be attached to the back end and be operated by side levers connected with those at the tront end, or in any other convenient way; but the way represented in the drawings is peculiarly applicable to planing the elliptical part of carriage wheel spokes.

Vhen it is desired to leave a greater, or more abrupt prominence on the article than can be done by the operation of the jointed lever-s, n, and n, (as the square part of a carriage wheel spoke,) a collet like that shown at a, Figs. l and 2, must be attached to the front, or toothed, center, c, back of the ratchet wheel, e. This collet in its smallest part, or least diameter, must be larger than the ratchet wheel, e, and made of such shape as shown in Fig. 2, or any other shape suited to the purpose for which it is to be used, so that where the greater, or more abrupt, prominence is required it will touch upon, and pass up the inclined plane of the bar, T, so as to elevate the inner part O, O, of the carriage and the toothed center, e, to the requisite height beyond what would be ettected by the operation of the jointed levers, a, and n.

The crank, E, and connecting rod F, F, must be of such length, and the inclined planes, P, and l", so located, that the end of the material will be carried entirely beyond the cutter wheel,each way, before the ratchet begins to revolve the ratchet wheel, so that each section may be planed true from end to end; otherwise the corners of square parts, &c., would be marred, and the sections, near the ends would be planed winding, so that t-he symmetry ot' the article would be injured or destroyed; but as this is a matter which every one who builds a machine, or is capable of using one will readily understand, it is unnecessary to be more particular.

)What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the jointed levers (n, and 11,) suspended by their upper ends, with the crank, (j) and connecting rod, (70,)j when so constructed and arranged as to elevate, or depress, the inner part (O, 0,) of the carriage, and the toothed center, (0,) in such a manner as to give a regular elliptical form to the polygon where the opposite longitudinal sections will be equal, and similar, when the whole is constructed, arranged, vand combined, substantially, as herein described.

2. I also claim the use of the notched, collet (cZ,) on the toothed center, (0,) and the curved bar, (T,) in combination with the jointed levers, (n, and m) to give regular,

land irregular, forms to different parts of the same elliptic polygon, when the whole is constructed, and combined, substantially, as

herein described.
