SAMUEL CARPENTER, OF FLUSHING, NEIV YORK. v

MACHINE FOR TURNING HUBS, TOOL-HANDLES, &c.

Specification of Letters Patent No. 11,777, dated October 10, 1854.

To all whom t may concern Be it known that I, SAMUEL CARPENTER, of Flushing, in the county of Queens and State of New York, have invented a new and Improved Machine for Turning Hubs, Tool- Handles, Sac.; 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 anneXed drawings, making a part ot this'specification, in which- Figure 1, is a plan or top view of my improved machine. Fig. 2,' is a side View of ditto. Fig.A 3, is a side view of the pulley, which gives motion to the stuff, and through which pulley the staif is fed to the cutters. Fig. 4, is a side View of the cutter stock.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to a new and useful machine for turningv and boring hubs tool handles, and other articles ot a beaded and regular curved form.

The nature of my invent-ion consists:

1st. In giving a rotary motion to the stuff to be turned and bored, by having the stuftI fed to the cutters through the center ot a pulley which is driven by a band wheel, said pulley communicating the rotary motion to the stuit, and allowing it to be fed through its axis at the proper intervals'.

2d. My invention consists in the peculiar mechanism devised for operating the cutters, bit or auger, and belt shipper. This mechanism will be fully described hereafter.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, A, Figs. 1 and 2, represent two horizontal bed pieces, supported by suitable standards, B, B. The above parts may be constructed of either wood or metal.

C, is a stationary head, secured to the bed pieces, A, A, by bolts, (a). On the upper part of the head, C, a pulley, D, is placed, said pulley having its axis, (b) running in suitable bearings, (c), (o), in the head, C. The axis, (Z9), of the pulley, D, has a square opening, (d), made longitudinally through, as shown in Fig. 3.

E, Figs. 1 and 2, is a movable and sliding head, which works on the bed pieces, A, A; and F, is a nut secured to the lower part of the head, E.

G, is a screw rod, which passes through the nut, F. The ends of the screw rod, G, work in suitable bearings, (e), (e), one at each end of the bed pieces, A, A. The screw rod running parallel with the bed pieces. On one end of the screw rod, G, there are two pulleys, H. I. One of the pulleys, H, is attached permanently to the screw rod, and the other pulley, I, works loosely thereon, and has a hollow arm, J, with a screw wheel, K, upon it, said screw wheel gearing into a horizontal worm wheel, L.

M, see Figs. 1, 2, and 3, is a transverse sliding bar, which works in suitable guides, (f), (f), see Figs. 1 and 2, on the upper part of the bed piece, A,A.

To the sliding bar, M, there is attached an upright, N, which forms a cutter stock for a finishing chisel, O. To one side of the upright, N, there is attached by a pivot, g), a cutter stock, P, more particularly shown in Fig. 4.

M', Fig. f1, is a spiral spring underneath the sliding bar, M.

The cutter or finishing chisel, O, has a cutting edge, made to correspond to the desired form of the articles to be turned. The cutter on the upper part of the stock, P,rep resented by Q, is merely a cutting ott tool, with a plain, narrow, beveled edge, as shown clearly in Figs. 1 and 4.

R,is astationary cutter or gouge attached to the side of the head,.C, as` shown in Figs. 1 and 2.

S, is a bit or auger attached to the ends of a rod, T, which slides in suitablebearings on the upper part of a frame, U, on the bed pieces, A, A. Around the rod, T, there is a spiral spring, (h), the use of which will be hereafter shown. V, is a bent lever, having its fulcrum at (i), one end of this lever is attached to the outer end of the rod, T, and the other end projects a short distance over the face of the worm wheel, L, see Fig. 1.

W, X, are two levers having the same fulcruln, 7'),-the outer ends of these levers also project over the faceof` the worm Wheel, L, see Fig. 1. The lever, W, is connected to the upright, N, of the slide, M, by a rod, (k), and the lever, X, is connected to the stock, P, by a rod, (Z), see Figs. 1 and 2.

On the face of the worm wheel, L, are three upright pins, (m), (n), (o), all of them are shown in Fig. 1.

Y, is a belt shipper attached to a lever, Z, said lever having its fulcrum at (p), see

" lever, Z, in its proper position.

cuts or roughs o the corners of the stuff,

- worm wheel, L, and the pin, (m), bears -on the same shaft, C', as the band wheel,

Fig. 1, and (g), is an upright attached to the lever, Z, and having a horizontal arm, (1"), which is directly in line with the hole, (d).-,in the pulley, D.

Y, is a spring catch which secures the A, is a band wheel, by which motion is given the pulley, D; and B, B, are pulleys the pulleys, B, giving motion to the pulleys, H, I. 1

Operation: rlhe st-uff to be turned, is made of square form by previous sawing, and of such al size as to pass through the square hole, (d), in the axis, (b), of the pulley, D, see Figs. 1, 2, and 3, the stuff being represented by D. One end of the stuff isplaced within the axis, (b), of the pulley, D, and the opposite end is supported by a center point, (af), in the sliding head, E. Motion is then given the shaft,l C', andthe band wheel, A', gives a rotary motion to the pulley, D, by means of a band, (b), and the pulley of course rotates the stu. The screw rod, G, also rotates at the same time, by means of a belt, (0), which at this time, passes around the pulley, H, which is attached to the rod, G, see Figs. 1 and Q. 'Ihe rotating of the screw rod, G, as the nutI fits around it, causes the stuff, D, to be moved through the hole, (d), in the axis, (b), of the pulley, D, and the stationary cutter, R, attached to thehead, C,

and the ends of the stuff, after passing' through the axis, Y(b), a requisite distance, comes in contact with the arm, (1"), and throws back the belt shipper, Y, which of course, throws the belt, (0'), from Vthepulley, H, to the pulley, I. The screw, G, now ceases to rotate, and the screw wheel, K, has a rotary motion, and gives motion t-o the against-one arm of the bent lever, Y, and thus throws the bit or auger, S, forward, andY into the ends of the stuff, D. The stuff, D', still rotating, but not moving forward through the axis,`(? The sliding bar, M, is now moved by means 0f the pin, (n), coming in contact with the end of the lever, W', and the cutters are consequently made to act upon the stuff, the cutter, O,v cuts the wood in the desired form, while the cutter, Q, at this time, merely cuts a recess into the stuH to Yallow the cutter, 0, to out clean at the end. The. pins, (m), (n), having passed the levers, V, W, the bit or auger,

S, is forced back to its original position by the spiral spring, (71,), and the cutter, 0,; is

forced back sufliciently to clear the stuft' by means of the spiral spring, M', underneath the slide, M. The pin, (n), now acts against the outer end of the lever, X, and forces forward the cutter, Q, the stock, P, of which works on the pivot, (g), and the finished article is cut olf, and the slide is forced back to its original position by the spring, M, and the belt shipper, Y, is thrown back, and the belt, (0'), is thrown upon the pulley, H, by means of a pin, (t), on the lever, X, striking a projection, (c), on the lever, Z, see Fig. 1'. At the next operation, the pin, (or), acts against the arm of the lever, V, the three pins forming an equilateral triangle on the face of the worm wheel, L.

By the above machine, hubs for wagons, tool handles, and all articles having a regular curved form, may be turned with the greatest facility. The length of each article turned, will be equal, because the extreme end of the stuff acts upon the belt shipper, and shifts the belt, (0'), at equal length of the article to be turned, and articles of different lengths may be turned by properly adjusting the arm, (r), so as to allow a greater or less length of stuff to pass through theY pulley, D, before acting against the arm, Y

I do not claim turning, boring, tapering andl shouldering handles either cylindrical or conical by meansy of hollow cutters, tapering cutters, bits or drills,`as none of these devices are new; but

What I claim as my invention and desire to secure by Letters Patent isf 1. The use or employment of the pulley D so constructed and arranged as to communicate a continuous rotary motion to the stuff to be turned, and to allow the same to be fed freely through its Iaxis at the proper intervalssubstantially as described, and for the purposesspecilied.

2. The arrangement, and combination of the pulleys H, I, screw, and worm wheels K, L, levers W, X, V, and slide M, for the purpose of operating the cutters, O, Q andV .vpose of causing the turned articles toV be -cut 0E from the stuft1 of equal length, as set SAMUELy CARPENTER. Witnesses:
