DOUIA O. PUTNAM, OF WAYNE CENTRE, YORK.
STAVE-CROZING MACHINE.
SPECIFICATION forming part of Letters Patent No. 543,893, dated August 6, 1895.
I Application filed February 3, 1893. Serial No. 1 P f h To all whom it may concern:
Be it known that I, DOUIA O. PUTNAM, of Wayne Centre, in the county of Wayne, in the State of New York, have invented new and useful Improvements in Stave-Orozing Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and. exact description.
My invention relates to stave-crozing machines which operate on jointed staves to'edge them, croze them, chamfer their inner faces, and bevel the outer face, the whole being done without the use of any of the ordinary coopers tools and bya-single passage of the blank through the machine.
Figure l is a front elevation of the machine for crozing, chamfering, and beveling the staves, the dotted lines indicating the feedtable. Fig. 2 is a top plan view of the machine, omitting the discharge table or chute. Fig. 3 is a transverse vertical sectional elevation of the machine complete. Fig. 4 is a side elevation of one of the, yielding tables, its mounting being in section. Fig. 5 is a front elevation of the same. Fig. 6 is a top plan of the arching-top presser-bar detached and enlarged and showing the outside-chamfering cutter mounted therein. Fig. 7 is a like view of one of the fingers upon the drum. Fig. 8 is an edge view of the same. Fig. 9 is a front elevation of the cut-0E saw and the crozing and inside-chamferingcutters mounted upon a single arbor ready for use. Fig. 10 is a top plan of the same. Fig. 11 is a sectional elevation of part of the drum, the finger thereon, the top presser-bar, and the outside-chamfering knife. Fig. 12 is'a plan View of the outside-chamfering cutter. Fig. 13 is a like view of the crozing-cutter. Fig. 14 is an edge View of the stave as crozed, chamfered, and beveled by the machine. Fig. 15 is a plan view of the equalizing-bar by which the staves are centered longitudinally.
A suitable frame is erected in which the shaft a is suitably journaled, provided with a drive-pulley a and a drive-pinion a", which drives the gear I), secured upon the axle b, suitably j ournaled in the frame, said axle also carrying the heads I)", said gear, axle, and
heads constituting the drum oft-he machine.
At equal distances apart the fingers c are adjustably secured to said heads by means of bolts inserted through the slots 0' and project outwardly therefrom, their outer ends being provided with a croze-groove d, Fig. 11, and inside-chamfer bevel d, an outside-chamfer bevel d", and a transverse rib d' the bases of said fingers projecting radially beyond said heads, substantially as shown, and creating pockets e between them, which receive the staves and in which they are carried by the rotation of the drum,being first set upon edge upon the rails h, which constitute the sides of the feed-table, and fed inward thereon into the pockets in succession as the drum rotates, said fingers picking them one at a time off from the bunch. These table-rails are pivoted upon thedrum-arbor, as at h, Fig. 2, and are adjustable as to the pitch of their inclinationby means of the support h" and the means shown for adjustment or their equivalent.
Upon each end of the frame an arbor 7c is journaled, provided with a drive-pulley 0, v
and mis a saw mounted upon said arbor, while m is a head also mounted thereon, provided upon its periphery with fiat faces n, upon which the inside-chamfering cutters p are secured, standing at the angle of the chamfer to be cut.
When a stave is picked up in a pocket in the drum and carried around under the curved-top presser-bar 'r they are also carried at each end onto and over the top of the curved table 8, mounted upon the rods 5' and having the springs s", which yieldingly support the table, the ends of the table fitting between guides t,erected upon the board t, secured upon the frame, said table being yielding according to the varying thickness of the staves and holding them insliding contact with the presser-bar while the cutters are crozing and inside-chamfering each stave, said presser-bar holding the stave against vertical movement and insuring perfect crozing and chamfering;
' In the presser-bar the out-side-chamfering knife or cutter u is adjustably secured in such manner that it will chamfer or bevel off the outside of .the stave B, as at 7.6, as an aid in putting on the hoops, the croze being marked o and the inside-chamfer v in Fig. 14.
When the staves are placed on edge on the feed-table the inner one bears against the stops w, Fig. 2, on the table-rails, and if a. stave is out of line longitudinally one of its ends will strike one of the vertical and inwardly-inclined spring-plates to, which are mounted upon the frame, and w" are rods connected to the free ends of said plates and to a rocker 10", Fig. 15, pivoted upon the top rail of the frame, so that by the joint action of these plates and equalizing-rods and rocker each and every stave is centered longitudinally and each end is cut off alike when they are brought into contact with the saws and the staves are cut of equal length. The saws are shown as provided with clearancenotches of ordinary construction, which may be omitted when desired. At the same time while the ends are being trimmed oh? the crozing-cutter is crozing the stave and the chamfering-knife is chamfering it, and also substantially simultaneously therewith the beveling knife is beveling off the outer face of each end of the stave as an aid in putting on the chine hoop or hoops.
The cha1nt'ering,crozing, and bevcling of the fingers on the drum is such that none of the cutters will strike them as the drum carries them around, though they are close thereto.
\Vhen upon the drum, the staves have a center-bearing upon the main gear.
Upon the frame and on each side springfingers 00, Fig. 3, are secured, in such relation that their free ends will bear frictionally upon the staves after they pass the cutters and retain them in the pockets without permitting any shifting until the staves come into contact with the bars 00', which pick the staves out of the pockets, so that they will then slide down the discharge-table or chute 3 finished and ready to be set up and tired.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. The feed table, provided with stops, and the vertical and inwardly inclined springs which extend across the inner end of the table, the outer ends of the springs being rigidly held, while their inner ends are con nected to an equalizing rocker, combined with the feed drum, provided with pockets, and means to revolve the drum, substantially as shown.
2. In a machine for making staves for barrels, a table upon which the staves are placed, equalizing springs which extend across the inner end of the table, a revolving feed drum provided with pockets, the curved top presser bars, each provided with a cutter, curved yielding tables placed below the presser bars, the bars for taking the staves from the pockets, and mechanisms at each end of the frame, for cutting off and finishing the ends of the staves, all combined to operate substantially as described.
3. The feed table, provided with a stop on each edge, the vertical and inwardly inclined spring plates, secured to suitable supports at their outer ends, and the pivoted rocking rod, mounted on the frame and to which the inner ends of the spring plates are fastened, all combined and arranged to operate, substantially as set forth.
4. A mechanism at each end of the frame for sawing off and finishing the ends 01? the staves, and a feed drum, provided with pockets, combined with the curved top presser bars, each provided with an adjustable cutter, substantially as specified.
