FREEMAN HANSON, OF BAE MILLS, MAINE.

s WOOD-TURNING'IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 272,242, dated February 13, 1883.

Application filed November 7, 1882. (No model.)

To all whom it may concern Be it known that I, FREEMAN HANsoN, a `citizen of the United States, residing at Bar Mills, in thecounty of York and State of Maine, have invented certain new and useful Improveementsin Wood-Turning Machines; and I do hereby declare the following to be a full, clear,

it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. Y

Figure 1 is a perspective view from the front side of the machine. Fig. 2 is a perspective from the rear side. Fig. 3 is a perspective view, showing more fully how the cutters or knives are mounted and worked. Fig. 4 are de tails showing in perspective -some of the many forms of the cutting-edges used.

This invention belongs to that class of wood-v working devices known as carvingor molding machines; and the novelty in the present instance consists in the manner of mounting and operating the tools which do the cutting or carving or like work, and in the mechanism for operating the same, and in the general and special details of the novel construction and combination of the several parts, all as will now be more fully set out and explained.

In the drawings, A denotes any convenient frame, to which the mechanism is secured or attached, and in which the operating parts are suitablymounted. Powermaybecommunicatedin any convenientway,and thus theshait-s,B, C,c,D, E,and F will be set in motion, as well as the knife or cutter sockets or severalheads, 1, 2, 3, 4, 5, and 6, mounted on shaft D. The shafts B, C, and c, which convey the motion ofA the several portions, are mounted at suitable points or places on the frame-work. The shat't D is mounted in the upper ends of the bearing-arms g of the frame G, toward the front of the frame A, and these bearings are pivoted at their lower ends, so as to allow theframe to swingfor instance, as now shown on shaft E. The shaft E passes across the frame in a direction parallel with the shafts B, C, and D, and by its pinion c operates the gears H andh, which regulate the turning of shaft F above it. This latter shaft is mounted in bearing-arms i, connected with and forming part of frame I, which swings on shaft E, according as it is actuated by the pitman K,attached at. any desired point to its lug i. The pitman K is worked by a disk and crank-pin, as 'now shown, or by any suitable eccentric on the -shaft C, to which it is attached.`

The wood L, which is to be cut or operated on by the knives or cutting-edges, is heldin proper position between the end of shaft F and a chuck, m, and can thus be turned at such desired rates of speed relative to the turning of the cutting-tools as may be determined by the number or size of gear or gears h on the connecting-arm c', between shafts E andF, and by the position of the end of pitman K in the lug47that is, by the joint position or independent position of these devices. as will be hereinafter described and explained. Each of the knives or cutters X, mounted on the shaft D, is fixed adjustably by set-screw in one of the heads of on arbor fixed at one end in a pulley revolving on a shaft 'mounted on D, while near the other end said' arbor is mounted in suitable bearing attached directly to the shaft D. This is all indicated clearly in the drawings, where d', d2, cl3, d4, d5, and d6 represent the several arbors 5 d d, te., the several pulleys, and dl d?, Src., the several bearings. vThe said several arbors are of different lengths, d being the shortest, and thence they increase regularly in length to the longest, d6. Two may be mounted, or as many as the size of the shaft will accommodate.

The revolution of the shaft I) will cause all the cutters or knives to havea general revolution, and theconsequent regularl y-recurrin g operation of the belt coming over the pulleys d will cause the several arbors to be operated Aknife or cutter 1.does its work, the knife or cutter 2 follows, and thus till the last cutter has done its work at the other end, afterwhich the same routine is repeated. In this way, only a very small part of the wood being acted on at any one moment, there is'the verysmall- IOC est, if any, danger of splitting or breaking or damaging the ivood in the process ot' working it-aii end, as all persons skilled iii turning well know, most desirable to be attained.

'lhe back-aiid-forth movement of the frame G, which carries the cutters or knives, may be regulated by means of the screw-shaft N and handledcranlmtin thefrontofthemachine, operated by the workman, and in this way any one of thev knives may be brought against the work and the several knives in any order desired, either in regular succession, as above stated, or otherwise.

The wood L may be rotated according to the number or position of the gear-wheels H and lt. and also by the position of the pitmaii Kin the lug i. When this pitinan is placed in the lowest hole in said lug the wood will be so offered to the cutters as to cause a concave shape to be produced, land when placed in the highest hole the cutters will produce a convex shape on the wood.

Any one of the cutters may be run alone by throwing all the other` driving-pulleys out ot' gear, or by fixing the pulleys of all the other arbors, or by any like means familiar to one skilled in this sort of machine.

While I have shown gears, as on shaft c, and belts to convey the motion, I may use belts alone or gears alone, or change them in any well-kiiown way familiar to mechanics and as shall most conveniently answer my end.

My machine is adapted for long work, as balliisters, as now shown in the drawings, on which all the knives can work; but I can, as above suggested` put in a short piece ot' wood adapted for one knife, or a piece adapted for two-that is, I can work any stock that can be pnt between the ends -of shaft F and the chuck a, long or short.

This machine, it will be perceived, is of comparatively simple structure, when the results it attaiusare considered, and is not costly. It will do its designed work very rapidly and with the most saving of stock, and inthe best manner.

As has been above intimated, I may put on arm c., any desired number and size of gearwheels h, so as to change the character ot' the motion ofthe wood.

The shape of the knives or cutter Xmay be as shown in Fig. 4, or of any desired shape or form.

Having thus described my invention, what I consider new, and desire to secure by Letters Patent, isl) 1. A revolving shaft having a series of revolving spindles mounted thereon, said spindles carrying cutter-heads located at different distances from the end of the main shaft, in combination with the work-carrying spindles of a lathe, substantially as described.

2. The rotary shalt D, having disk d and a series of brackets, 17, secured thereto. said brackets projecting radially from the shalt in different directions and located at unequal distances from said disk, in combination with a series ofspindles, d d2, &c.,journaled at their ends in said disk, and brackets and carrying cutter-heads on their ends projecting beyond said brackets, substantially as described.

3. 'Ilie combination of the revolving shaft, having a series of rotary cutter-carrying spindles mounted thereon, with the swinging frame carrying said shaft and the work-holding spindles of a lathe, substantially as described.

4. The combination of a swinging frame carrying a cutter-shaft provided with an adjusting-screw, which engages with said lraine and with the main frame, with the swinging frame carrying the work-spindles, and means, substantialb` as described, for operatingr said frame from the driving-shaft, substantially as described.

5. The combination ofthe swinging frame carrying the cutter-shaft, having screw-rod N swiveled thereto, with the swinging frame earrying the workspindles,said frame. having arm t" secured thereto, pitman K, adjustably connected to said arm, and driving-shaft and crank connected to said pitnian, substantially as described. s

6. The combination of the swinging frame carrying the rotary shalt D, having bearings for the rotary cutter-spindles d d2, Snc., said spindles having cutter-heads located at different distances from the end ot' shaft D, with the liand-driven screw N, swiveled thereto, the swinging frame carrying the work-spiiidle, vand means, substantially such as described, for oscillating said frame from the drivingshaft, substantially as described.

7. The combination ot' the swinging frame carrying the rotary shaft D, having bearings for the rotary cutter-spindles d' d2, Src., said spindles having cutter-heads located at different distances from the end'of shaft D, the swinging frame carrying the work-spindles, and means, substantially such as described, for oscillating said frame from the driving-shaft, substantially as described.

The combination of the swinging frame carrying the cutter-shaft, having-a haiid-driven screw swiveled thereto, with the swinging lraine carrying the work-spiiidles, and means, substantially as described, i'or oscillating the saine, shaft E, upon which said frames are pivoted, and gearing from said shaft to rotate the work-spindles.

In testimony whereof I affix my signature in presence of two witnesses.

'FREEMAN HANSON.
