WILLIAM F HUTOHI NSON, OF NEW YORK, N. Y.
'STAVE-MACHINE.
SPECIFICATION forming part of Letters Patent normgsee, dated August 1 a, 1895.
Application filed April 6,1895 Serial No. 544,704- (No model.)
To all whom it may concern:
Be it known that I, WILLIAM F. HUTOHIN- soN, of the city, county, and State of New York, have invented new and useful Improvements in Stave-Machines, of which-the following is a full, clear, and exact description.
My invention relates to improvements in a machine for and method of converting a strip of veneer into'staves. It is well known that veneer turned from a rotary veneer-machine is very smooth, and it is also understood by those familiar with veneers that any necessary grooves may be turned in the veneer as it comes from the machine, and that its edges may be beveled, if desired. In consonance with this idea my invention contemplates turning'a strip of veneer from a log, with the croze-grooves in the strip and with the edges of the veneer beveled, and then passing the strip through a machine which will cut the strip of veneer crosswise, thus forming it into a series of staves, the length of which corresponds to the width of the veneer strip, and at the same time giving to the staves the'necessary end taper. It will be observed that run lengthwise of-the staves; that the staves will be shaped ready for use and will be to all intents like an ordinary shaved stave.
The object of my invention is to produce a very simple, durable, and efficient machine, which is adapted to rapidly cut a strip of veneer of the kind described into staves, which has a series of rotating knives arranged on a revoluble cutting-drum to cut the veneer, and which has a carrier serving also as an ejector and adapted'to feed the Veneer to the machine and carry away and deposit the formed staves.
A further object of my invention is to pro-. .vide simple and efticient means for ejecting the waste material which is out between the tapered ends of the staves, and in general to provide forthe quick conversion of the veneer strip into staves.
To these ends my invention consists of a method and machine which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
elevation of the machine.
Figure l is a broken side'elevation, partly in section, of the machine embodying my invention. Fig. 2 is a central vertical cross-section of the machine. Fig. 3 is an enlarged detail longitudinalview of one end portion "of the cutting-drum and of the mechanism for ejecting the waste material from between the knives thereof. Fig. 4 is a broken rear Fig. 5 is an enlarged detail sectional view of the brush device used in connection with the ejecting mechanism shown in Fig. 3. Fig. 6 is an enlarged detail plan view of a portion of the carrier and ejector. Fig. 7 is a detail side elevation of the said carrier and ejector. Fig. 8 is a crossesection of one of the carrier-guides,
and Fig. 9 is a broken detail perspective View 1 of a strip of veneer adapted to be cut into staves.
The machine is provided with a suitable frame 10, which has journaled in it a revoluble cutting-drum 11., this, as illustrated, being hollow, and the drum is carried bya shaft 12, which may be driven in any suitable manner. Around the face of the drum are knives 13,
which are arranged in pairs, the knives of each pair being oppositely curved, as best illustrated in- Fig. 4:, and thus a stave out between a pair of knives will, be widest in the middle and will taper toward its ends. These knives may be fastened to the drum in any convenient way or may be formed integral with the drum, but, as shown, they are dovetailed into the face of the drum. (See Fig.1.)
Opposite the cutting-drum 10, and preferably above it, is a bearing-drum 15, which is provided with grooves 14 to register with the knives 13, and the drum 15 is carried by a shaft 16, which is journaled in the frame 10 and is .driven by gear- wheels 17, 18, and 19, connecting with gear-Wheels 20 on the main vshaft 12; but it is of course understood that travel tangentially to the drum and eventually move outward from between the knives it will be seen that the staves will be lifted from the knives and carried away by the carrier. These cross-bars 21 are connected by links 23, which thus form an endless carrier, and the cross-bars are also connected loosely b chains 23, which prevent them from tipping over and so interfering with the work of the machine.
The upper portion of the carrier travels in an almost level position through the machine and over the drum 10, and the carrier is guided and moved by sprocket-wheels 24, which are arranged triangularly in the machine, as shown clearly in Fig. 1, one pair of these sprocket-wheels having their shaft provided with gearwheels 25, which connect by gearwheels 26 with gear-wheels 20 on the shaft 12. It is necessary to have the carrier made and timed so that the cross-bars 21 shall accurately register with the spaces between the knives 13.
To guide the carrier and enable the crossbars to move with necessary precision over the drum 11, the carrier has journaled on its sides rollers 27, which run on angle-guides 28, these being secured to the frame 10 at opposite ends of the drum 11 and being curved slightly upward, as shown clearly in Fig. 1. The carrier will work without the an gle-guides '28, but the latter are preferably used. It will be noticed that the cross-bars 21 will not eject the waste material which is cut from the veneer and which will lie in the small spaces 13 between the knives 13, and to provide for ejecting this material the construction described below and shown in detail in Fig. 3 is used.
Between alternate pairs of knives 13 and opposite the spaces 13 are the waste or supplemental ejectors 29, whichlie normally fiat against the face of the drum 11, but which at necessary points are forced outward, so as to carry out the waste material and bring it into contact with brushes to be presently described, which remove the said material from the drum. Each ejector 29 (see Fig. 3) is carried by arms 30, which at their inner ends are pivoted to 'a suitable support on the drum 11, and the arms have a sliding connection, as shown at 32, with a rod 33, which extends outward endwise from the drum 11 and has at its outer end a truck 34:, running in a hollow cam-track 35, which is fast on the frame 10 and is circular, so that the trucks 34 may edges of the knives 13, and the material on the ejectors is thus carried out to a point where it may be conveniently removed, as presently described.
At opposite ends of the machine and opposite the place where the ejectors 29 move outward, which point is preferably on the under side of the drum 11, are revoluble brushes 36, which are preferably of metal, and the faces of which are preferably roughened so that they will readily engage the waste material carried outward by the ejectors 29. These brushes 36 turn toward the ends of the machine and they engage the said waste material and throw it outward from between the knives 13. The brushes 36 are carried by shafts 37, which are driven by beveled gears 38and 39, (see Fig. 5,) the latter of said gears being carried by the shaft 40, which is journaled on the frame 10 and has a suitable driving-pulley 4:1. The outer ends of the shafts 37 are journaled in arms 42, which are in turn journaled on the shaft 40, and the inner ends of the shafts 37 are journaled in boxes 4E3 on a cross-rod 44, which is adjustable up and down in the slots 45 of the arms 46 on the machine-frame 10, (see Fig. 1,) and it will thus be seen that the brushes may be moved in and out with relationto the drum 11, so as to bring them into position to engage the waste material already referred to, while they maybe held in any de sired position by tightening the nuts 17 on the ends of the rod all.
I do not confine myself to this particular means of adjusting the brushes 36, nor even to the use of the brushes 36, as with many kinds of material the ejectors 29 will throw out the waste material without using the brushes.
It will be noticed that the journals of the bearing-drum 15 and of one side of the sprocket-wheels 24 are adjustable; but I have not referred to this fact particularly, as no novelty is claimed for it.
The operation of the machine is as follows: A strip 48 (see Fig. 9) of veneer is turned from a log with the croze-groove 19 in the strip near its opposite edges, and with the edges beveled in the usual manner, as shown at 50. This strip is fed into the machine at one side upon the carrier and ejector 22, and as it passes between the drums 11 and 15 the strip is cut by the knives 13 into staves, which are carried outward from between the knives by the ejecting cross-bars 21, and the staves are dropped at the back end of the machine. The waste material out between each pair of staves is ejected from between the knives by the ejectors 29 and the mechanism already described in detail, and thus it follows that a continuous strip of veneer may be fed into one side of the machine, while formed staves drop continuously from the back side of the machine.
It is evident that this method provides for rapidly cutting a fine quality of staves, and it is also apparent that the shape of the staves maybe changed at will by changing the shape of the knives 13, and hence that any ordinary stavessuch as barrel, firkin, tub, and analogous staves'may be formed by my machine and method.
Having thus described my invention, I claim as new and desire to secure by Letters Patent V 1. A stave machine, comprising a revoluble cutting drum having circumferential knives, a bearing for the knives, and a flexible beltlike, carrier moving tangentially across the face of the drum, the said carrier having cross bars to fit between the knives and serve as ejectors, substantially as described.
2. In a stave machine the combination with the revoluble cutting drum audits peripheral knives, of the flexible belt-like carrier traveling across the face of the drum and provided with cross bars entering between'the knives of the drum, the rollers journaled on the carrier, and the guides at the drum ends to sup-. port the rollers, substantially as described.
3. In a stave machine the combination of the cutting drum, the peripheral knives, the flexible belt-like carrier traveling across the face of the drum and provided with cross bars entering between the knives, and means as the chains 23, for preventing the tipping of the cross bars, substantially as described.
4. A stave machine, comprising a revoluble cutting drum having peripheral. knives arranged in pairs, a carrier traveling across the face of the drum and provided with cross bars extending between alternate pairs of knives to serve as ejectors, and a second series of 6. The combination with the revoluble cutting drum having peripheral knives, and the radially movable ejectorsbetween the knives, of the swinging arms pivoted to the drum and to the ejectors, the longitudinally movable rods connected to the arms, and a cam mechanism for moving the rods in and out, substantially as described.
7. The combination with the cutting drum having peripheral knives, of the radially movable ejcctors between the knives, the arms pivoted to the drum and to the ejectors, the rods secured to the arms and projecting from the ends of thedrum, and means, as the circular cam tracks and the trucks on the rods,
for actuating the arms and 'ejectors by the turning of the drum, substantially as described.
