A suitable casing .-1 having a supporting base 2 is provided with bearings for the main driven shaft 3 having pulleys or band wheels 4 and 5, one fixed andthe other loose for receiving motion from a source of power by means of a belt, not shown. The shaft 3 carries Within the casing a disk 6 equipped with radially disposed knives or cutters 7 for the purpose of stripping the bark from the log L which is presented to the cutter carrying disk through the opening 8 in the front of the casing.l A counter shaft 9 which is suitably supported in parallel relation to the irain shaft 3 is driven from said main shaft by means including a belt 10 and a friction clutch comprising a loose pulley 11 and a clutch member 12, which.

latter is splined upon the shaft 9 ior rotation therewith, said clutch member being movable into or out of engagement with the loose pulley 11 by means of a bell crank 13 having a forked arm 14 engaging the hub of the clutch member 12. The bell crank 13 is fulcrumed upon abracket 15 which is associated with the frame or casing of the machine.

The countershaft 9 carries a bevel pinion 16 meshing with a bevel gear 17 on a shaft 18 which .is supported for rotation in suit able bearings upon and transversely of the casing 1. Pivotally mounted upon the shaft 18 are twov arms 19, the outer ends of which afford bearings for a shaft 20 which re ceives motion from the shaft 18 by a chain or link belt 2l. The shaft 20 carries wheels or disks 22 which are equipped with teeth or spurs 23 of rhomboidal shape, said teeth being detachably secured. by suitable fas-l tening means, such as bolts 24, thus enabling theteeth 23 on the wheels or disks 22,

and whichmay and are preferably secured detachably so as to be capable of being reversed when desired.

Arranged in front of the frame or casing 30 1 is an upright frame or casing 25, the frontI of which, facing the front of the casing 1, is equipped with grooved guide members 26 in which a slide 27 is supported for vertical movement, said slide being pref- 5 erably provided with a rack 28 on the rear face thereof. rlhe frame 25 affords bearings for a shaft 29v carrying a gear wheel 3 0 meshing with the rack-28. Said shaft 1s also equipped with a hand wheel 31 having spokes 32, whereby it may be conveniently turned or manipulated. The slideis connected by a flexible element, such as a cable 33, which is guided over a suitably arranged pulley 34 with a counterweight 35, whereby said slide is approximately balanced so that it may be moved upward or downward with little eort by rotating the shaft 29. The slide 27 is provided with lugs 36 affording bearings for a yoke 37 with which a rod 38 is slidably connected, said rod being actuated in an upward direction from the slide by a suitably arranged spring 39. The rod 38 carries at its outer end a yoke 40, the limbs or side members of which, 41, are pivotally mounted upon the shaft 20. It will be seen that the rod 38 and related parts and the arms 19, together with the shaft 20, corn` bine to constitute a toggle structure, and that by moving the slide 27 upward or downward, the shaft 20 carrying the toothed wheels 22 may be raised or lowered and at the same time be moved outward from or inward in the direction of the face of the frame or casing 1.

The frame 26 is provided with suitably disposed lugs 36 with which arms 37 are pivotally connected, said arms being provided with slots 38 engaging the shaft 20. The arms 37 extend in the direction of the casing 1, and the purpose of said.arms is to engage the log that is being operated upon for the purpose ofy preventing the latter from jumplng or from being displaced while it is being subjected to the action of the'barking machine.

Supported for movement transversely between the casings or frame structures 1 and .25 is an endless carrier or conveyer C which may be suitably constructed of wire cables 42 upon which Vflights 43 of hard wood are` clamped or secured at suitable, intervals, said cables being guidedpover suitably supported drums 44. One of said drums is mounted upon a shaft 45 which receives motion by means of a belt or band 46 from the driven main shaft of the machine. Clutch means of suitable construction may be employed to enable the conveyer C to be operated intermittently at the will of the operator, but such means are not absolutely essential, and being of ordinary and well known construction, it is not deemed necessary to particularly illustrate the same. The frame or casing 1 is provided adjacent to the conveyer C with means for supporting a shaft 47 carrying toothed or spiked rollers 48 adapted to support the log that is to he operated upon.l said roller carrying shaft being 4provided with a pulley 49 which is connected by a belt or band 50 with a pulley 51 on the shaft 18 from which motion will thus be transmitted to the roller carrying shaft. The belt 50 is guided over idlers 52 upon the casing 1, one of said idlers being supported adjustably in order that the belt may be kept under proper tension.

Suitably mounted on the boxes or bearings of the shaft 47, or supported in any convenient manner, are skids 47 which are inclined upwardly in the direction of the aperture 8 in the casing 1, said skids being preferably extended into said aperture. These skids constitute bridge pieces which by their presence prevent any possibility of the log that 'is being operatedv upon being stuck or caught back of the supporting rolle ers 48, assuming the log to be of such small diameter as to render such an accident liable to occur.

Supported beneath the upper lead of the conveyer C adjacent to the edge of the latter which is distant from the casing 1 isa vertically slidable yoke 53 having rollers 53 engaging and supporting the underside of said upper lead so that by moving the yoke upward, the edge of the upper lead of the lconveyer may be tilted in an upward direction, the portion ofthe lead which may thus be tilted being positioned adjacent to the roller carrying shaft 47. The slidable yoke 53 is connected by a rod 54 with an arm 54 extending radially from a rock shaft 55 equipped with a foot lever 55 whereby it may be actuated. A suitably supported hooked lever 56 is connected by means of rods 57 and bell cranks 58 with the arm 59 of the bell crank 13 by meansv of which the friction clutch member 12 is actuated.

In practice, a log placed on the conveyer C will be carried by the latter until it reaches a point adjacent to the roller carrying shaft 47 which-is supported beneath and adjacent to the opening 8 in the casing 1.

`When the log reaches the proper positlon,

miv

20 carrying the toothed wheels 22, both of said shafts 47 and 20 deriving motion from the shaft 18 which is geared to the countershaft 9 to which motion is imparted by means including` the friction clutch l1, the movable member of which is actuated by the bell crank 13 which, as stated, is operated by the foot lever 55. At the same time, theA operator by 4turning the hand wheel 31 lowers the slide 27, thus actuating the'toggle mechanism whereby the toothed wheels on the shaft 20 are'placed in engagement with the log which is thus forced in the direction of the cutter carrying disk through the opening 8 in the casing 1. Should the log be an exceptionally large one, as indicated in dotted. lines in Fig. 1, it will be engaged directly by the toothed links of the chain 21, and it will thus be properly manipulated in the same manner as though engaged directly by the toothed wheels or disks 22. Said chains serving also to prevent the log from jumping or from being displaced upwardly by any cause. The log will be rotated by the joint action of the toothed rollers 48 on which it .is supported and the toothed disks 22, `or the toothed chains 21, as the case may be, and the bark will thus be gradually removed from the log. After the log has been peeled, the slide -27 is moved upward to disengage the toothed wheels 22 .from the log which is now permitted to roll back upon the conveyer, whereby it is carried off, its place being taken by a fresh log.

. Instead of actuating the slide 27 by means of the hand wheel 31 and related parts, the said slide may be connected byv a link rod 62 with a piston movable in a cylinder 63 which is suitably connected by a valved duct 64 with a source of supply of compressed air, steam or other liuid under pressure, whereby the piston may be actuated. An exhaust valve 65 is also provided, the same being suitably connected with the inlet valve 66 on the duct 64 to be operated jointly therewith. By this simple mechanism the feeding device of the barking ma chine may be operated with practically no effort on the part of the operator. The modified construct-ion just described has been illustrated in Fig. 10 of the drawings.

As will be seen from the foregoing ldescription, taken in connection with the drawings hereto annexed, I have provided simple and improved means whereby logs may be conveyed to the barking machine and fed to the latter, the logs being held in engagement with the rotary cutter carrying disk with any degree of pressure which may be found most suitable to insure a successful operation.
