WV. M. SLOANE, OF BUFFALO,` NEW YORK.

STAVE-MACHINE.

Specification of Letters Patent No. 20,737, dated .Tune 29,'18158.

To all whom 'it may concern:

Be it known that I, WILLIAM M. SLoANn, of BuEalo, in the county of Erie, in the State of New York, have invented new and useful Improvements in Sta've-Dressing Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure I, is a side elevation. Fig. II, rs a plan. Fig. III, is an elevation of the vertically moving frame and the cutters supported therein, and the cams, and the c onnection thereof to the frame and gearing for driving the same; Fig. IV, end elevation of the feed and pressure rollers and gearing for driving the same. Fig. V, represents the arrangement of that portion of the gearing which connects with the main wheel to drive the feed and pressure rollers and one of the cams. Fig. VI, is a plan of the cam and diagram of the formula for obtaining the form thereof.

The nature of my invention relates, lst, to operating two rotary adjustable cutters in a vertically moving frame, as hereinafter more fully set forth; 2d, in the arrangement and combination of the said cutters in relation to a revolving bed, feed-rollers and former, as herein set forth. 3d, in the construction of a cam of peculiar form for the purpose of communicating the required movement to the said frame supporting the said cutters.

A (Fig. I) rotating bed or main wheel upon which the stave is fed to the cutters and formed; o, cog rim attached to said wheel; c, main frame, or bed which supports the machine; c, .0, secondary frame which supports the gearing and cutters;

(Z (Z, gear wheels which drive the feed and pressure rollers. Upon the opposite end of the shaft is a smaller wheel, (Z2, (Fig. IV) which meshes in with cog rim b.

e, e, e, e, series of gear wheels on same shafts with feed and pressure rollers; F, vertically moving frame, which supports the two revolving cutters; y

G, driving pulley on said cutter shaft. The arrangement of these pulleys and shafts is more fully shown in Fig. III.

I-I, upright posts, which guide the frame z' z', set screws, which with the rubber springs J J, regulate the pressure of the rollers; K, cam, which gives the proper vertical movement to the frame F, and cutters, in order to dress the edge of the stave upon the required bevel and bilge; L, guide or former under which the stave passes to hold it to the bed.

M, nib, projecting from the face of the rotating bed, against which the stave is Aplaced to be fed to the cutters; it also acts as a gage to bring the stave to the action of the cutters at the proper point.

N, table, on which the stave is placed in order to be fed to the cutters; M n, parallel gage;

O (Fig. II), main driving pulley. A small pinion O2, (Fig. IV,) is upon the opposite end of this pulley shaft and meshes into the cog rim (52,) on rotating bed.

P, horizontal revolving cutter which dresses the outside of the stave; Q, pulley which drives the same; R R, cutters, supported in the vertically moving frame, and which dress t-he edges Aof the stave; G, Gr, pulleys which drive the same; S S, feed and pressure rollers;

25, t; feed rollers on same shaft with middle wheel c. These rollers are convex (the reverse of the feed and pressure rollers above them, which are concave) and in connection with the face of the rotating bed, give the inside transverse curve to the stave;

u, a, (Fig. III) arms, connecting the cams K to the frame F. These arms are connected to a circular band which surrounds the cam, o-r instead of the band the arms may set upon the cam, and the frame weighted so that the frame will follow the cam.

The cutter shafts are made adjustable in the circular slots r2 so that the cutters may be set upon any given level, and adjusted to any width of stave and any size barrel.

o fu, set'screws, which hold the cams to shaft W and W1.

X X, pinions on same shafts with cams. These mesh in with cog rim b and b2. The gearing is so arranged as to give the cam one revolution while the rotating bed passes the distance between the nibs M, or the length of the stave.

Z, (Fig. IV,) support and journal bearing for shaft of driving pulley; Z2, support and journal bearing for shaft of pinions Z and d2; (Z2, pinion, which meshes in with cog rim b and drives the feed gearing c, c, c, c.

Letters of like name and kind refer to like parts in each of the figures,

A peculiar form of cam, in connection with the revolving motion of the cutters, is requisite in order to give the required form oi stave to make a barrel of any required lcurve or bilge. Hence I have adopted the 'following formula to be observed in the conof equal parts (l, 2, 3, &c.) as the chord is divided, and draw radii (l, 2, 3, &c.) through each of these points corresponding to the perpendiculars of the chord. 6th, on each of these radii, commencing with No. l lay oil distances equal to the height of the perpendicular of the corresponding number on the chord. 7th, when all these points are obtained draw a line through them. This line (W H) will determine the form of the cam.

Operation: The stave which is to be dressed is laid upon the table N, and against the gage As the bed revolves the stave is moved quickly against the gage M until taken by the feed and pressure rollers by -which it is carried along under the former L, to the cutters. The cutters R It, are at their highest posit-ion when they commence to cut the stave, and gradually descend until the revolving bed has carried the stave one-half its length, or to the center of its bilge at which point the cutters commence and continue their upward movement until the other half of the stave4 is jointed. The horizontal cutter P at the same time dresses the outside of the stave upon its transverse curve. The cam communicates the required vertical movement to the frame l?, and cutters R, R, and each stave is dressed upon its required bevel, bilge, and curves with mathematical correctness.

I claim-f 1. Operating the two rotary cutters (It, R,) in a vertically moving frame (IQ) substantially as herein set forth.

2. I claim the arrangement oi the cutters R, R, and P, relatively to the revolving bed A, former L, and feed-rollers for the purposes and substantially as herein set forth.

3. I claim the cam (K) when constructed according to the formula, and used for the purpose as herein set forth.
