J BARK-REMOVlNG MACHINE.

' SPEGIFCATION forming part of Letters PatentrNo. 735,793, dated August 11, 1903. Applicationled August 25, 1 902. 'Serial No. 120.926. (No model.)

Be it known that I, J osnrn MOREAU, ject of the KingfofGreat Britain, residing at St..Germai n de Grantham, countybf Drummond, ProvincevofQuebec, Canada, have invented certain ncrv/and useful glmprovements in BarkeRemoving Machines; and Ldo hereby declarethat'the following is adfull, clear,

and exact description of the invention,l such as will enable yothers skilled iii the art to which y it appertainsto'make and use the same.

Myinvention relate-s. tofv a .machine'for rel moving the bark frein logs, and especially those logs Whichzare.usedinthe manufacture of wood-pulp, the object being to quickly and completely remove as much as possibleV ofthe barkwhile removing the minimum amount of wood ber. "1. l l

The object 'of my inyention isto produce a simplifiedand improvedmachine over that described in another application iiledby me for a similar machine, SerialNo. 26,306, filed September 23, 1901. Y

One of the improvements herein set forth lies in the construction of the angularly-set feed-wheels, which are so arranged in the present machine as to be regulable to vary the rapidity of feed, and therefore the angle of said feed-wheels, by a shifting bar and lever set at either end of themachine; and, f urrher, a holding-down arm, which extends over thev logs during the processof rossing, or cutting the bark therefrom, is .arranged to be operated by the same levers which regulate the position of the feed-wheels.

Another improvement which I have devised and applied in the present machine lies in the independent mounting of the two Vertical logturning wheels on opposite sides of the barkremoving cutter, .whereby either may be raised or lowered independently of each other and of said cutter,.and they are furthermore providedrwith means for independent hori- Zontal adjustment for-purposes whicliwill be presently explained.

Still another improvement lies in the provision of saddles at intermediate points along the travel of the logs and at those places where the distance between adjacent cutters or feed- Wheels is considerable, so that short logs may be readily supportedand are prevented from falling down between the wheels and other `mechanism during their travel through the machine.,-

Still another feature of my invention lies in the improved arrangement of the driving mechanism and A general lcollocation of the parts of the machine.

My invention further resides `in the constructions and combinations Which'are hereinafter more specifically described, and set forth in the claims.

In the drawings accompanying this specification I .have shown the mostimprovedembodiment of my bark-removing machine, and whereiny- Figure lis a plan view of the complete machine. Fig. 2 is a side elevation thereof from the left side. Fig. 3 is a longitudinal sectional elevation taken on the line 3 3 of Fig. l, the feed-wheels being shown as having Itheir axes set in the section-plane. Fig. Lis a longitudinal sectional elevation taken on the line 4 4 of Fig. 1 -that is to say, through the main shaft of the machine. Fig. 5 is a vtransverse sectional elevation taken on the line 5 5 of Fig. 1 looking toward the front of the machine. Fig. Gis a transverse sectional elevation taken on the linev 6 b' of Fig. 1 and looking toward the rear of the machine. Figs. 7, 8, and 9 are respectively a transverse median section and side elevations from opposite sides of one of the log-turning wheels. Fig. lO is a side elevation of one of the cutter-heads; and Fig. 11 isa transverse section throughthe cutter-head, taken in the diametrical plane 11 11 of Fig. 10.

The machine comprises a stationary supporting-framework 12, the front end or feed ing end of which is shown on the right of the drawings and the rear or delivery end on the left. On the right of lthis frame-that is to say, on the upper' side of Fig. 1 aremounted a pair of pillow-blocks 131upon'the end beams 14 of the'frjame and a series of larger intermediate pillow-blocks 15 on the intermediatel transverse beams 16 ofr the frame, these latter pillowblocks ybeing three in number, as shown, and in these pillowfblocks is` rotatably journaled the main shaft 17, which extends the complete length of the machine. On this shaft are keyed at intermediate points thereon two cutter-heads, (designated 18 and 19, respectively,) the former of which carries ICO . for driving the machine by means of an y suitable belt 24, leading from the source of power, and at the opposite or front end of the shaft 17 is mounted a pulley 25, which is connected through intermediate mechanism with the other parts of the machine to be driven, as will be hereinafter described. On the sides of the beams 16, which support the main shaft, are mounted

brackets

26 and 27, the latter being two in number and mounted on the two rearmost beams 16 and adjacent faces of the latter and on opposite sides of the bark-removing cutter 19. These two brackets 27 are not fixed to the beams 16, upon which they are supported, buthave independent forward and lateral adjustments thereon, as will be presently described; but the remaining brackets 26, which are four in number and are located on both sides of the front beam 16 and the other sides of the rear beams 16, are fixed thereto in stationary positions by bolts 28 or other suitable means. Each of the brackets 26 carries at its upper end a projecting sleeve 29, which surrounds the main shaft 17 and has mounted thereon one of the six log-turning wheels 30, which turns loosely on said sleeve and is secured against lateral motion thereon at the base of the bracket 26 by an overhanging flange 30, which partially surrounds the inwardly-projecting end of the hub of the wheel 30, and at the other end by a collar 32, Which is fixed to the end of the sleeve 29 by a setserew 33. The brackets 27 similarly have projecting from their ends sleeves 34, which also surround the shaft 17, but whose internal diameter is considerably larger than that of the shaft in order to enable the vertical and lateral adjustment of the log-turning wheels just referred to. On these sleeves 34 are similarly mounted other log-turning wheels,which are designated for distinction respectively 31 and 32, for these two wheels perform different functions, as will be seen hereinafter. These

wheels

31 and 32 are likewise held against endwise movement upon their pivots by overhanging fianges 35 and adjustable collars 36, fixed thereto by set-screws 37. On the opposite or left -hand side of the frame of the machine are mounted a series of upstanding posts 38, herein shown as six in number, corresponding with the six log-turning wheels, and each post carries adjustably mounted thereon one of the six feed-wheels 30. Each feed-wheel 3) is arranged to rotate loosely on an axle-bolt 40, which is secured in a swivelhead 41 at an angle some fifteen to twenty degrecs above the horizontal plane, while the swivel-heads 41 are j ournaled in thrust-collars 42, formed on the upper ends of the stationary posts 38, so that the swivel-heads rotate on vertical pivots, as shown. Beneath the collars 42 the swivel-heads are extended farther, all except the first swivel-head, which merely has a collar-flange 43 fixed thereon to prevent vertical movement in its bearing; but the rearmost five swivelheads have loosely mounted thereon sleeves 44, which have formed on their upper ends bevel-pinions 45, which mesh with teeth 46 on the rear orflower face of the respective feed-wheels. The edges of these feed-wheels are serrated or toothed, as shown at 47, for the purpose of gripping the logs and assisting their turning or rolling movement, so that the successive portions of their periphery are presented to the knives. On the lower ends of the sleeves 44 are mounted other bevel-pinions 48, which mesh with a series of bevelpinions 49, carried on a longitudinal shaft 50, journaled in transverse beams 51,which rest on the longitudinal beams 52 of the frame which support the posts 38. At the front end of this shaft, which projects slightly beyond the bearing-block 51, is fixed a sprocket-wheel 53, over which passes a chain 53, connecting it withthe drivingmechanism to be presently described.

The swivel-heads 41 have each extending laterally therefrom toward the left o1' outside of the machine an arm 54, and these latter are all pivotally connected in parallel planes to the longitudinal shifting bar 55. On the lower side of this bar, at the center thereof, is formed, as shown, a block 56, which has an eye therein, th ou gh which passes a lon gitudinal somewhat-flexible shaft or pole 57, which is secured to the block 56 by a set-screw 58. Below the bar 55 and the pole 57 on the side of the machine-frame is mounted a rock-shaft 59, which is loosely carried in bearing-blocks 60, secured to the side of the frame, and on its ends are fixed quadrant-plates 61, which are slotted both longitudinally and transversely, as shown at 62 and 63, respectively, the former slot being such as to divide the plate 61 into two laminar portions between which is journaled ahand-lever 64, the pivotpin of which is shown at 65 wit-hin the arcuate slot 63. Each of the two hand-levers 64 at the opposite ends of the rock-shaft 59 is pivotally connected, as by a pin 66, to one end of the polel 57, so that by swinging the lever 64 about its pivot the pole 57 and bar 55 may be adjusted in position and in consequence the angle which the axle-bolts 40 and the feedwheels make with the longitudinal axis of the machine. In orderto hold the feed-wheels in their adj usted position, I may further provide the upper edge of the arcuate slots 63 with oblique serrations 67, in connection with which operates a small latch -bolt 68, resiliently pressed into the notches or scri-ations 67 by a spring 69, both the bolt and spring being mounted on the side of the lever 64.

ICO

IIO

thereof, is mounted a rock-arm 70, which extends upwardly and is connected at its upper end by a link 71 with the holding-down lever shown at 72, 'which is pivoted at an intermediate point 7 3 to the extending end of a saddle 74,' the office of which will presently be described. The lever 71 has an upwardly-extending tail portion 75, to Which is connected the link 71, and its operative portion extends over the saddle 74-,thatis to say, over the path of the log passing through the machine, as shown in Fig. 5,-and holds the latter down against the cutters and feed mechanism.

IWill now describe the mechanism by which the log-turning

wheels

31 and 32, which .operate in connection with the cutter 19, are adjusted. y

The brackets 27, as shown in Fig. 5, have a crossshaped outline and are held up against the beams which support them by straps 7 S embracing the horizontal arms of the cross. The lower end of each bracket 27 is rounded, as at 79, and rests against eccentric cams, (designated 80 and 81, respectively,) which are fixed, respectively, to the ends of the shafts S2 and 83, passing through the opposite ends of the machine and journaled in the beams 16, which support the main shaft. The front end of the shaft 82 has fixed thereto a treadle-lever S4, which has a rearwardly-extending arm 85, connected by a spring 86 with a piece of the frame, so as to hold the lever S4 resiliently in raised position, the upper limit of the motion of the lever being regulated by a stop-pin S7. In order to assist the action of the treadle S4, I may also provide, preferably, a hand-lever SS, likewise keyed to the end of the shaft 82 or forming a part of the same piece on which the treadle 84 and the arm 85 are formed, if desired. It will be seen that by depressing the treadle 84 or drawing the handle 88 to the left the ca1n 80 will be rotated so as toraise the bracket 27 and by consequence the log-turnwheel 3l, and hence will alter the position of the log with respect to the cutter 19, so as to cause the latter to cut more or less deeply into the log, as may be desired. In a similar manner the shaft 83 is extended to the rear end of the machine and has mounted at its rearend a treadle-lever 89, which is held inraised position by a spring 90, secured to the base of the machine, so that by depressing the lever 89 the rear bracket 27, and hence the logturning Wheel 32 is likewise raised with relation to the cutter. Further, to provide for horizontal adjustment of the log turning wheels, and in addition to hold the brackets 27 steady, each bracket has a slot 91 formed in its outwardly-extending arm in which runs a pin 92, which is secured to the end of the adj usting-bolt 93, passing through the side beam 94 of the frame and adjusted in its endwise position by nuts 95. The lateral positions of the log-turningwheels 31 and 32 do not need frequent adjustment, but may be adjusted once for all at different intervals, according to the wear and setting of the cutter-blades in the cutter-head; but as for reasons which will be presently seen it is necessary to operate the wheels up and down with the travel of each log through the machine the wheels are provided lwith the foot-levers 84 and S9,Which are designed to be worked by two independent operatives stationed respectively at the feed and delivery ends of the machine. The shaft S2 is preferably utilized also in addition to its main function for carrying the counter-shaftdriving mechanism which connects the main shaft 17 with the two shafts which drive the feed-wheels andl the log-turning wheels, respectively. It is in the form of a sleeve 96, loosely mounted on the shaft S2 and xed in longitudinal position thereon by adjustable collars 97. At its end the sleeve 96 carries a pulley 98, which is connected by a belt 99 with the pulley 25, and also two sprocket-wheels 100 and 101 are fixed to the sleeve 96, over the former of which passes the chain 53a, and over the latter another chain 102, which connects the sprocket -Wheel operatively with the sprocket-Wheel 103, located on a longitudinal counter-shaft 104, journaled parallel to and in nearly the same horizontal plane with the main shaft, as shown in Fig. 1. This shaft 104 has also mounted thereon a series of spur-pinions 105, which mesh with gears 106 formed on the respective log-turning Wheels. These latter are formed as shown in Figs. 7, 8, and 9, being provided with a series of oblique outwardly-extending ribs 107, each of which is provided with a plurality of sharp points 108, which bite into and assist in turning the' log, which rests against the wheel, as shown. The set of log-turning

wheels

30, 31, and 32 and the feed-wheels 39 either slightly overlap each other or lie in nearly tangent planes, so that the log is adapted to lie in the spandrel-shaped space between the two sets of wheels and when lying in this position is continuously rotated by their rotation and is fed along by the oblique setting of the feed-wheels. The oblique ribs 107 on the log-turning wheels also assist the advance movement, but their primary function is merely to rotate the log against the cutters, so as to present successive portions of its periphery thereto.

It will be understood by those familiar with the manufacture of wood-pulp that the logs for this purpose are cut into short sections of four feet in length, which is a preliminary to barking. However, some of these sections are necessarily less than four feet-as, for in* stance, three feet-in length, and while the machine herein described is adapted to support logs of the normal length, yet short logs will fall through the machine at intermediate points thereof if not otherwise supported. For this reason l provide saddles 74, located, respectively, at the center between the two

cutters

18 and 19 and at the ends of the machine,-the two end saddles being for the purpose of sustaining the logs as they enter and are delivered from the machine.

IOO

For preventing the bark fragments separated by the cutters from flying about and preventing contact of operatives with the revolving cutter-knives I provide a guard-plate 109, secured` to the beam 94 and overhangiug the main shaft. Also I prefer to provide the journal-boxes of the main shaft with oilcups 110, which are covered by hinged plates 111, whereby chips and shavings of bark are excluded.

The preferred construction of the cutterheads is shown in Figs. 10 and 11, comprising a metal forging or casting 112, forming the hub of the cutter-head and having a radial flange 113 at one side, which is secured to the body of the cutter-head 114 by means of screw-bolts 115. rlhe said body 114 is recessed around its periphery and carries the cutter-blades 2O or 21, adj ustabl y fixed thereto by screws, as shown.

To prevent endwise motion of the shaft 17, I may provide the shaft with a series of annular grooves 116 opposite one of the bearings, the bearing-blocks having corresponding ribs which engage with said grooves and forming th rust-eollars against which the sh aft works.

The two adjustable log-turning

wheels

31 and 32 on opposite sides of the main cutter 19 serve dierent objects, that of the first wheel 31 being to regulate the depth of cut generally upon the log according to the thickness of the bark thereon, so as to enable the operative to regulate this according to his skill and judgment from the front of the machine as lie sees the log pass through the same. On the other hand, the wheel is regulated by the operative at the delivery end, so as to take a deeper cut from the hinder end of each log than is taken from the body thereof, this being done by depressing the lever 89 as the rear end of each log comes opposite the cutter 19. The purpose of this is connected with the fact that after the bark has been removed as completely as possible by the machine, which has to be done without removing any of the wood therefrom, there still remain irregular places, such as depressions in the log, from which the bark has not been removed and from which it must be removed by hand. 'lhis is done by a draw-knife in the hands of the operative who works over the surface of the log, but as it is not convenient 'to remove the bark from the end farthest from the operator by this method under ordinary circumstances it has been necessary to turn the log after removing the bark from lone end and then remove it from the other.

rwasted is of trilling value compared with the amount of time required in turning the log in the hand-cutting process. As the turning is thereby avoided I am enabled by this ma-v chine to save considerable time heretofore necessary in the hand trimming of the logs before they are ready for the pulp-mill.

The logs being fed into the machine are laid upon the foremost saddle 74 and between the two front wheels 30 and 3f), the latter of which is idle, but the log is immediately set in rotation by the turning-wheel 30, and the wheel 39 rotating by contact therewith causes the log to be pushed along over the other wheels of the series, and hence come in contact successively with the

cutters

18 and 19. During the action of these cutters the log` may be held down in case it shows any tendency to rising out of the action of the cutters by means of the holding-down lever 72, which is'operated by swinging one of the` hand-levers (54 inwardly, and at the same time the rate of advancing of the log is regulated by the longitudinal movement of the same hand-lever which adjusts the position of the feed-wheels, as above described.

\Vhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise forni shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modiications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
