Description

UNTTED sTATEs PATENT oEEicE.
CHARLES HOYT, OF WEST AURORA, ILLINOIS.
DEVICE IN STAVE MACHINERY.
Specification of Letters Patent N0. 15,423, dated July i29, 1856.
To all fwhom it may concern:
Be it known that I, CHARLES HoY'r, of lVest Aurora, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Machines for Dressing and J ointing Staves for Barrels, Casks, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of t-his specification, in which- Figure 1, is a longit-udinal vertical section of my improvement, Fig. 3, showing the plane of section. Fig. 2, is a t-ransverse vertical section of ditto, y, y, Fig. 3 showing the plane of section. Fig. 3, is a plan or top view of ditto.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to a new and improved device for jointing the staves and giving them the proper shape or swell.
To enable those skilled in the art to fully understand and construct my invention, I
Iwill proceed to describe it.
A, represents a rectangular frame, to the lower part of which and at one end, a lever B, is pivoted, said lever being connected by a cord a, to a sliding bed or plate C, which is tted on the upper part of the frame A, and has spiral springs Z9, b, bearing against it as shown in Fig. 3.
D, is a center strip placed longitudinally on the frame A, and fitted in a groove or recess at the center of the bed or plate O. The strip D, is stationary and is grooved longitudinally and has a feeding block or slide E, fitted within it, said block or slide being connected by a rod c, with the upper end of a bent or right-angled lever F, which is pivoted to an arm el, on a cross piece of the frame A, see Fig. l. A spiral spring e,
bears against the feeding block or slide as shown in Figs. l and 3.
Gr, G, are plates placed on the bed or plate C, one at each side of the strip D. These plates have oblique slots f, made in them, two in each and pins g, which are attached to the bed or plate c, fit in the slots f, see Fig. 3.
H, H, are two feed rollers which are placed one above and the other below the center strip D, as shown clearly in Fig. 1.
I, I, are two aws which work upon pivots g', g, attached to frames J, J, which are allowed to slide or work laterally in the frame A. One end of the frames J, are connected to levers It, L, which work on a pin or bolt z', in the underside of the strip D, see dotted lines, Fig. 3, the pin or bolt being allowed to work in a slot in the under side 0f the center strip.
K, K, represent two wedges Lwhich are connected at their lower ends. These wedges are in a `vertical position and pass upward against one end or side of the frames J, J; a spring z, passes through the lower part of the wedges and a rod j, passes through the end of the spring, said rod having a knob or cross head on its upper end. The lower end of the rod j, is attached to a reciprocating block L, which has rods 7c, 7c, attached to it, said rods working through guides Z, as shown in Fig. 2. The block L, is connected by a pitman m, to a strap n, which is fitted around an eccentric o, on a shaft M. This eccentric has a pin p, on one of its sides, said pin acting against the lever F, as will be hereafter described. To the upper end of the block L, two bars N, N, are pivoted said having two vertical wedgedshaped bars p, p, at each end. Two similar bars O, O, are also pivoted to the block L; the outer ends of said bars having vertical bars g, g, attached to them, on which shafts or arbors 1', r, are placed, said shafts or arbors having cutter heads s, s, on their upper ends. The upper ends of the shafts or arbors r, r, have their bearings in horizontal plates t, t, which are attached to the upper ends of the bars g, g, said plates working within the frames J, J.
P, P, are springs which bear against the under sides of the bars O, O.
Q, Q, are weights which are attached to the ends of the two jaws I, I.
R, R, are two cylinders provided with cutters for dressing the inner and outer sides of the staves and S, S, are two discharging rollers, which, as well as the cylinders R, are placed one above and the other below the strip D.,
The operation is as follows: The staves T, shown in red, are got out of the proper size and are placed one at a time upon the strip D, and the lever B, being depressed, the two plates G, G, are moved laterally inward and adjust the stave T, precisely in line with the feed rollers H, H. The pin @on the eccentric 0, acts against the lower part of cisely at the proper time, between the feed rollers I-I, H, and between the two jaws I, I, the stave expanding the jaws and causing the two frames J, J, and cutter heads s, s, to move a little outward at equal distances from the strip D. The cutters on the heads s, s, then act upon the end of the stave, one at each side, the frames J, J, and heads s, being held permanently by the wedgeshaped bars K, which are moved upward at this time, the heads being nearest together at this point, that is, when acting upon the stave. As the stave is moved along, the wedge-shaped bars p', p, are moved upward by the eccentric o, and the bars g, Q, and cutter heads s, s, are gradually thrown outward or expanded, ltill the center of the stave reaches the point precisely between the two heads; the heads s, s, are then thrown gradually inward by the springs P, for the wedge shaped bars p, begin to descend till the stave has entirely passed through between the heads, the stave then passes between the dressing cylinders R, R, and is discharged from the machine by the rollers S, S, the stave being cut with the swell or proper taper, as shown in Fig. 3. The heads s, s, it will be seen, expand in a circular direction, because the inner ends of the bars O, O, are pvoted to the block L, as previously shown and the edges or sides of the stave T, will consequently always be cut with the same level, however much or little they may be expanded, and this level always forms a radius line from the center of a circle, of which the pivot of the bars O, O, is the center. The staves, therefore will be perfectly jointed and in an expeditious manner.
I do not claim the cylinders R, R, for dressing the stave, for they have been previously used, but
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1.V I claim adjusting the staves T, in line with the feed rollers H, H, and jaws I, I, by means of the sliding bed or plate C, and laterally sliding plates G, G, arranged as shown and described.
2. I claim the feeding block E, when operated by the spring e, lever F, and eccentric 0, substantially as shown, for the purpose of feeding the staves to the cutters.
CHARLES HOYT.
