To LZZ whom t may concern,.-

Beit known that I, JOSEPH MOREAU, a subject of His Majesty the King of Great Britain, residing at St.Anne Du Sault,county of Arthabaska, Province of Quebec, Canada, have invented certain new and useful Improvements in Rossing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in rossing-machines of that class wherein a rotary cutter is employed in connection with means for rotating a log with relation to such cutter, whereby the bark is removed from or peeled od the log bythe action of the cutter, because the log is turned continuously or progressively, so as to present new surfaces to the cutter.

One objectfthat I have in view is the pro-y the log, thus adapting the machine to prop-4 erly peel the bark from crooked or irregularshaped logs wherein it is necessary to give a relatively slow advancing movement, while in the case of straight and symmetrical logs the speed may be increased in order to amplify the productive capacity of the machine, it being understood that such variation in the speed of the advancing log is obtainable without affecting or changing the speed of the main shaft or other parts of the machine.

A further object is the provisionof means for cutting off the knots,the stumps of boughs, and other excrescenses on the log, particularly on irregular-shaped pieces of work, such trimmingof the log being performed automatically on the same and in advance of the-rossingor bark-removing operation,tl1us reducing logs to a condition which is best calculated to secure good results when the work is fed to the rossing-cutter and obviating any interference with such cutter by the knots and other excresceuses on the log.

A further object of the invention is the provision of an emergency work-depressing device which in case a crooked or badly-shaped log is placed in the machine is adapted to be manipulated so as to force the log in adownward direction, so as to make the feed mechanism have positive engagement with such log, whereby the latter may be rotated and advanced to good advantage.

A further object of the invention is to pro- .vide means for regulating the depth of penetration by the rossing-cutter into the bark and the log, and thereby adjust such cutter to secure good results, such regulation of the cutter mechanism being easily performed while the machine is at work.

A further object is to equip the machine with means for carrying away the bark and other matter removed from the work; furthermore, to provide means for cutting the peeled logs into sections of suitable length and to provide a supplemental or auxiliary peeling device which may be advantageously used to remove any bark that may remain on crooked logs after the latter shall have been 'subjected to treatment in the main machine.

With these ends in view the invention consists in the novel combination of lmechanisms and in the construction and arrangement of the various parts for service, as will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated a preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure lis a plan view of the complete machine for trimming logs, removing or rossing the bark therefrom, cutting the logs into sections of the required length, and for peeling the bark, if necessary, from short sections of the log. Fig. 2 is an elevation taken from one side of the machine, the same being a view looking inthe direction 0f the arrowM on Fig. l. Fig. 3 is a longitudinal sectional elevation taken in the plane ofthe dotted line 3 3 on Fig. 1 looking in the direction of the arrow. Fig. 4 is an elevation looking at the right-hand end of the machine shown by Figs. l to 3, inclusive. Fig. 5 is a. vertical transverse section taken in the plane of the dotted line' 5 on Fig. 3 looking in the direction of the arrow. Fig. 6 is an ICO , per ends of the series of bearing-posts 8 arev enlarged longitudinal sectional elevation through the rossing-cutter and the parts associated therewith for the regulation of the cut on the work, the plane of the section being indicated by the dotted line 6 6 on Fig. 1. Fig. 7 is a view in end elevation of the rossing-cutter, the same looking at the left-hand end of the cutter shown by Fig. 6. Fig. 8 is a vertical cross-section through one of the feed wheels and the means for adjusting the same. Fig. 9is a Vertical cross-section through the supplemental peeling device, the plane of the section being indicated by the dotted line 9 9 on Fig. 1 looking in the direction of the arrow. Fig. 10 is a detail sectional View through the knot-removing cutter. Fig. l1 is a detail perspective view of the cutter-head forming the knot-removing cutter.

The same numerals of reference denote like and corresponding parts in each of the several gures of the drawings.

5 6 designate the longitudinal sills or platforms, which are suitably secured upon the crosssills 7. The sill 5 is somewhat wider than the sill 6, and the two sills are spaced at proper intervals one from the other, although they are disposed in parallel relation The Wide longitudinal sill 5 supports a series of substantial bearing posts 8, which are firmly secured upon the sill and are provided at their upper portions with the shaft-bearings 9, each bearing-post having an offstanding bracket-arm 10, which extends upwardly and rearwardly therefrom, each bracket-arm of the bearing-posts terminating in a shaftbearing 11. The shaft-bearings 9 at the uparranged in alinement with each other longitudinally of the machine for the accommodation of the main shaft l2, the same extending the full length of the machine, so as to occupy an operative relation to the sawing mechanism and to the supplemental peeling mechanism. The right-hand extremity of the main shaft 12 also finds a bearing 13 in an additional bearing-post 14, and this righthand extremity of the main shaftis equipped with the fast and loose pulleys 15 16, respectively, around either of which may be adjusted the driving-belt 17. The left-hand portion of the shaft l2 also finds support in the bearings 18 of the additional posts 19,v and these bearings are disposed beyond the left-hand portion of the main rossing-ma-y chine, so as to assist in supporting said lefthand end of the main shaft in proper relation to the sawing mechanism and to the supplemental peeling mechanism.

The cross-sills 7 are provided with shaftbearings 2O at points between the longitudinal sills or platforms 5 6, and in these Vbearings is journaled the counter-shaft 2l, the latter being arranged in a horizontal position between the longitudinal platforms and extending in the direction of the length of the machine, (see

Figs. `

2, 3, and 4,) the extreme left end of said counter-shaft being journaled in a bearing 22, which is provided on a V bracket-arm 23, that is fastened to the inner edge of the'longitudinal sill 5, said bracket being provided at a point between the sawing mechanism and the supplemental peeling mechanism. (See Figs. 2, 3, and 9.) The right hand portion of the counter-shaft is provided with a pulley 24, that is encompassed by a crossed belt 25, the latter being driven by a pulley 26, that is secured to the righthand extremity of the main shaft 12, thus driving the counter-shaft directly from the main shaft. The counter-shaft has operative connection with the knotremoving cutter, the rossing-cutter, the two series of feedwheels, the bark and refuse removing conveyers, and an element of the supplemental peeling mechanism, which operative connections will hereinafter more fully appear.

27 designates a counter-shaft, the same arranged in a horizontal position at the upper right-hand side 0f the machine, so as to lie above and parallel with the main shaft 12. Said counter -shaft 27 is journaled in the alined shaft-bearings 11, which are provided in the series of bracket-arms 10, that extend upwardly and outwardly from the bearingposts 8, and this counter-shaft 27 is provided at its left-hand end with a sprocket-wheel 28, around which passes a sprocket-chain 29, that is operatively fitted to a sprocket-wheel 30, which is secured on the counter-shaft 21, whereby the counter-shaft 27is geared to and driven from the counter-shaft. (See Figs. 1 and 3.)

31 32 33 34 35 36 designate one series of feed-wheels, which are loosely mounted on the main shaft 12 and are thereby supported in operative relation to the work and on one side of the latter. The feed mechanism also contemplates another series of feed-wheels, which are indicated by the numeral 37, the last-named series of feed-wheels being disposed in opposing relation to the first-namedv series of feed-wheels'3l to 36, inclusive, and said feed-wheels 37 being shiftable with relation to the line of feed or advancement of the log, whereby the feed-wheels 37 may be disposed at an angle to the path of feed, while the feed-wheels 3l to 36, inclusive, rotate constantly in a given position with relation to the path of the feed. The feed-wheels 37 and the means for adjusting the same will be hereinafter more fully described.

Each of the feed-wheels 31 to 36, inclusive,

is provided with a hub 38, said hub having` an axial opening 39 which exceeds the diameter of the shaft 12, and in this axial opening of the hub is loosely fitted a bushing 40, the same'arranged next to the shaft 12 and loosely supporting the feed-wheel thereon, so as to minimize friction and wear on the parts and to prevent the constant motion of the shaft 12 from affecting the feed-wheel. I prefer to provide each bushing with a flange 41 at one end, which flange is adapted to bear IOO IIO

6o Wheels 34 35.

against one of the shaft-bearings 9, all as more clearly shown by Figs. 6 and 10. Each of the series of feed-Wheels 3l to 36, inclusive, is furthermore provided with a solid rim 42 5 and with a series of circumferential spiral ribs 43. It is to be understood that each feed-wheel has its working circumference formed with a number of these spiral ribs, each rib being disposed in an inclined or io spiral direction across the circumference of I5 by Fig. 4. The rear end ofthe rib terminates in an abruptshoulder 44 and is equipped with a spur or tooth 45, which extends outwardly beyond the plane of the rib. The Dspiral disposition of the series of ribs 43 zo makes the following or rear ends of the ribs disposed in overlapping relation to the advancing ends of the series of ribs, vand thus the shoulders at the rear ends of the ribs, as Well as the spurs or teeth at said ends of the ribs, are adapted to have proper engagement with the work or log in a manner to rotate the latter'on its axis and at the same time enable the spiral ribs to assist in giving the forward feed or endwise movement to the log.

Each feed-Wheel of the series 3l to 36, inclusive is also provided with a series of sprocket-teeth 46, with which engages an endless sprocket-chain 47, that is driven by a sprocket-pinion 48, made fast on. the coun- 3 5 ter-shaft 27, a series of these sprocket-wheels 48 being secured to this shaft -in positions to aline with the sprocket-teeth on the series of feed-wheels. The described series of feedwheels rotateconstantly in a given direction 4o with relation to the path of the feed of the and progressively advanced endwise in a uniform manner.

By reference to Figs. l and 3 it will be seen that the pair of feed-wheels 32 33 are disposed between two adjacent bearing-posts 8. The

zo pair of feed-wheels 34 35 are similarly disposed between two other bearing-posts 8, while the feed-wheels 3l 36 are mounted on the main shaft l2 at points outside of the series of three bearing-posts 8. The work is introduced into the machine at the righthand end thereof, so that it will be engaged by the feed-

wheels

31, 32, 33, 34, 35, and 36 successively, and hence the Work passes by the feed-wheels 32 33 before it is fed to the I take` advantage of this fact by introducing the knot-removing cutter in operative relation to the feed-

Wheels

32 and 33, so that said cutter will operate on the log before the work is in position to be acted upon by the rossing-cutter, which is operatively disposed with relation to the feedwheels 34 and 35, thus combining in the machine two cutters, `one of which serves to trim the log and reduce it to the proper condition for action upon the log by the other cutter. The knot-removing cutter is shown by Figs. 1, 3, and 10, and it consists of a recessed cutter-head 50, the radial limbs of which are united at one end by a web 5l and Which is rotatively fixed to the main shaft by a key 52, fitted in its hub 53. The cutter-head is provided with suitable recesses 54, which recesses open through the circumference of the cutter-head to form the throats 55, adapted to receive the blades or knives 56, the latter being secured to the cutter-head within the throats thereof, all as more clearly shown by Fig. 10.

The blades or knives 56 of the knot-removing cutter-head are arranged to have their beveled or operative edges terminate at or close to the active edges of the feed-wheels 32 33 and the parts of the knot-removing cutter-head 50 are thus adapted to operate on a log, which is advanced endwise past thecutter-head in a manner for the knives to remove the knots or short boughs which may remain on the log, thereby trimming the latter to a substantially uniform or symmetrical condition, which will enable the rossing-cutter to operate to the best advantage in removing or peeling the bark from the logs.

The rossing-cutter occupies a similar relation to the pair of feed-Wheels 34 35 that the knot-removing cutter does to the feed-Wheels 32 33, and this rossing-cutter is similar in construction and operation to the knot-removing cutter, except that the bladesof the rossing-cutter are made to project beyond the active edges of the feed-Wheels 34 35 and also except that I have provided suitable means for regulating the depth of penetration int-o the work by the knives or blades of this rossing-cutter.

By referring to Fig. 6 of the drawings it will be seen that around the bushing 40 of the feed-wheel 34 is placed an eccentric sleeve 57, the same corresponding in length to the bushing 40 of said feed-Wheel 34, and it is provided. at its outer end with a sprocket- Wheel 58, the latter being exposed at one side y or face of the feed-wheel 34. This eccentric sleeve constitutes a tubular shaft for the feed-Wheel 34, said eccentric sleeve or shaft having an axial bore adapted to loosely and snugly iit upon the bushing, while the external cylindrical circumference of the sleeve is eccentric to the axis of the bushing 40 and the main shaft 12. The recessed cutterhead 59 of the rossing-cutter is provided at one side with a web 60, uniting the radial limbs thereof, and is also provided with a Series of openings or recesses 62, which extend through the cutter-head from one side thereof toward the web 60, and these recesses open'through the circumference of the cutter-head 59by the formation of openings which constitutethroats 63. Through the throats of the cutter-head pass the blades or IOOy IIO

knives 64, which are fastened firmly tothe cutter-head by bolts or screws.

The cutterhead 59 is provided with a sleeve or hub 65, mounted on the main shaft l2 and rotatively secured thereto by a key 61. vThe blades or knives 64 Vof the cutter-head 59 lie between the two feed-'wheels 34 35, and they are disposed so that the active edges of said knives will project beyond the active edges of the geared to the sprocket-Wheel 58 on the sleeve 57 and arranged in the following manner: This shaft is arranged in a horizontal positionbetween the'two series of feed-wheels and below the plane of the axes thereof, so that the adjusting-shaft is at all times out of the way of the work, said adjusting-shaft being journaled in suitable bearings 67, that are provided on the stationary cross-pieces 68 of the machine-frame. The shaft is provided at each end with a hand-wheel 69, and at or near its middle the shaft is equipped with a sprocket-wheel 70, that is in alinement .with

the sprocket-Wheel 58 on the eccentric sleeve or tubular shaft 57, and the two sprocket- Wheels 58 are operatively connected together by an endless sprocket-chain 7l. (See Figs. 3 and 5.) The provision of the hand- Iwheels 69 at opposite ends of the shaft enables the rossing-cutter to be adjusted and regulated by an attendant stationed at either end of the machine.

I will now proceed to describe the other set of feed-Wheels 37, the means for supporting the same, and the means for adjusting them, reference being had to Figs. l, 2, 4, 5, and 8. Each feed-wheel 37 is provided with a radial ange 72, the same having a Working edge formed by the series of spurs or teeth 73, and each feed-Wheel is furthermore provided within the Working edge thereof with a series of long or deep gear-teeth 74, the same adapted to have intermeshing engagement (notwithstanding the angular relation of the feed- Wheel to the line of feed) with gear-pinions 75, that are mounted on the feeder-driving shaft 7 6. This feeder-driving shaft is arranged in a horizontal position and on the opposite side of the machine from the cutterdriving shaft 27, the said shaft 76 being journaled in bearings 77, which are provided at the upper ends of the vertical posts 78, the latter being erected upon the longitudinal sill 6. The feeder-driving shaft has 'the pinions 75, secured at intervals corresponding to the spaced positions of the series of feedwheels 37, and this shaft 76 is provided at one end with a belt-pulley 79, which is encompassed by a crossed belt 80, that is fitted to a Fig. 8.) It will be understood that a series of the brackets 85 are employed for the support of the series of feed-wheels 37 and that said feed-wheels are mounted individually by short shafts, which are separately fastened to the brackets. The series of feed-Wheels and the brackets are so arranged on the longitudinal sill 6 that the working edges 73 of the feed-wheels are in opposing relation to the active ribbed edges of the feed-Wheels 3l to 36, inclusive; but instead of mounting the series of. feed-Wheels 37 for movement in a constant plane I have provided means whereby the relation of the feed-wheels 37 to the line of feed may be shifted in order that said feed-wheels 37 constituting one series may be simultaneously caused to assume angular positions with relation to the line of the feed. It is therefore to be understood that the feed- Wheels 37 of one series employed in the machine may be shifted to different angular positions with relation to the feed-Wheels of the other series 3l to 36, inclusive, and at the same time the series of feed-wheels 37 are positively driven by gearing the same to the feeder-driving shaft 76, the dimensions and form of the gear-teeth on the feed-Wheels 37 and the gear-pinions 75 being such as to permit of the intermeshing and operative relation of the feed-wheels to the shaft 76 at all points in the different positions of said feed- Wheels to the line of feed and to the opposing series of the feed-Wheels 3l to 36, inclusive. In lieu of the gear-pinions 75 and the gearkteeth on the feed-Wheels 37 I may employ other forms of gearing to connect the feedwheels 37 operatively With the shaft.76-'as, for instance, sprocket-Wheel and chain gearing may be employed or pulley-and-belt gearing may be substituted therefor.

In order to shiftably support the feedwheels 37, the brackets therefor are provided with the pivotal bolts 86, the same eX- tending loosely through openings 87 in the sill 6 and provided With the nuts 88, whereby the brackets are pivotally mounted on the sills 6. These brackets are shiftable in hori- -zontal planes around the vertical axes afforded brackets of the series. The arm 89 of the pivoted bracket on the right-hand end of the machine is extended beyond the shipper-rod 91 in order to form a handle 93 for the convenient manipulation of the shipper-rod, the movement of which affects all the pivoted brackets so as to simultaneously adjust all the series of feed-wheels 37.

By reference to Figs. 1, 4, and 5 it. will be seen that the feed-Wheels of the two series are grouped in pairs, which are disposed in opposing relation, and the active edges of these pairs of alined feed-wheels are brought quite closelytogether, as more clearly shown byFigs. 4 and 5, so that thelog is adapted to rest upon and to be supported by said series of opposing feed-wheels. The feed-wheels of the two series are driven to rotatein the same direction, each series of feed-wheels being positively rotated by intermediate gearing connections with the common counter-shaft, and the eect of the combined operation of these two series of feed-wheels is to rotate the log upon its axis in a direction contrary to that of the cutters and at the same time to give the log an endwise advancing movement in the direction of the length of the machine. The rotary motion of the log is due to the engagement of the active edges of the two series of feed-wheels which rotate in one direction; but the advancing endwise movement imparted to the log is due in part to the presence of the inclined ribs on the series of feedwheels 31 to 36 and to the angular relation of the feed-wheels 37 to the line of feed. By shifting the series of feed-wheels 37 simultaneously, so as to increase the angle of inclination of the feed wheels 37 to the line of feed, said feedwheels are caused to coact with the other series of feed-wheels in a manner to increase the speed of the end wise movement of the log; but by decreasing the angular inclination of said feed-wheels 37 tothe cooperative other series of feed-wheels 31 to 36, inclusive, the feed-wheels 37 are made to act in a manner so as to decrease the speed of advancement. of the Work.

When the machine is operating on crooked logs, it sometimes happens that the active edges of the feed-wheels cannot have proper engagement with certain portions of the log in order to effect the desired feed thereof. From practical experiments which I have made it is found that if pressure is exerted on thelog which is sustained by the two series of feed-wheels the latter may have proper engagement with the work in order to rotate and advance the same. In the present machine I employ a pressure device which normally remains inactive and which is adapted to be brought by manual adjustment into service. This pressure device is in the form of a long arm 94, arranged centrally in the machine and adapted to extend over the series of feed-wheels. This pressure-arm 94 is loosely sleeved at 95 upon the feeder-driving shaft 7G, as shown more clearly by Fig. 5,

tendant when stationed ateither end of the machine.

It is well known that machines of this class when they remain in service for any considerable length of time cause the accumulation of a large quantity of bark and chips around the floor;'but to obviate the necessity for constantly cleaning away the accumulation of refuse I have provided o-bearing conveyers 103 104, which are arranged to traverse the sill or platform 5 directly below the knotremoving cutter and the rossing cutter. These conveyers are provided with lags 105 or the equivalents thereof, whichare arranged to travel or to sweep close to the upper side of the platform or sill 5, and said conveyers are preferably embodied in the form of endless sprocket-chains, which are fitted to the driving-sprockets 106 and to the idler-sprockets 107, the former being secured to the connter-shaft 21, while the latter are mounted on the idle conveyer-shaft 108, which is journaled in the pillow-blocks 109. The endless conveyers travel in the direction indicated by the arrow in Fig. 5, so as to carry the bark, chips, knots, and other substances removed from the log away from the platform and from beneath the knot-removing cutter and the rossing-cutter, thus keeping the space below the machine practically clear.

From the early part of this specification' it will be recalled that the main shaft 12 was described as extending through bearings 18 on the standards 19 at the left-hand end of the machine, and at this end of the machine I have erected a suitable framework 110, adapted to support the saw-table 111, as well as the framework 112 for the support of the shaft 113 of the feed-roll 114, all as clearly shown by Figs. 1, 2, 3, and 9. The main shaft 12 carries a rotary saw 115, which has operative relation to the saw-table 111, and after a log 'shall have emerged from the two series of feed-wheels provided in the main machine said log may be placed on the table 111 and fed to the saw 115, so as to be cnt thereby into proper lengths.

The main shaft 12 extends in front of the feed-roll114, which is journaled in the framework 112 at the extreme left-hand end ot' the platform 5, and on this main shaft 12 is secured a rotary cutter-head 116, the same having blades 117. (See Fig. 9.) This cutterhead is in opposing relation tothe feed-roll 114, and this cutter-head and the feed-roll constitute an ordinary bark-peeling mechanism, the cutter-head being driven bythe shaft IOO IIO

the operation of the machine, but, on the contrary, its use depends entirely upon the condition of the log after it emerges from the machine.

This being the general construction of my improved machine, the operation may be described briefly as follows: The log is placed on the opposing pair of feed-wheels 31 37 at the right-hand end of the machine, and these feed-wheels operate on the log to rotate and impart endwise movement thereto until the log shall have been moved into position to be engaged by the next pair of feed-wheels 32 37, and this operation is continued as the log advances through the machine, because it is successively engaged with the successive pairs of feed-wheels. As the log moves endwise past the cutter-head 50 the knives thereon act upon the knots, &c., in order to trim the log to a proper condition, and the continued advancing movement of the log through the machine brings its surface opposite to the cutter-head 59, the blades of which 'operate on the log in order to peel and remove the bark therefrom. It is evident that the depth of the cut by the blades 64 may be regulated by adjusting the position of the feed-wheel 34 from the shaft 66. The bark and other refuse which are removed from the log are carried from the machine by the conveyers 103 104. The log may be thrust down upon the p feed-wheels 33 34 35 by manipulating the rock-shaft lever 102 in a manner to depress the arm 94, thus bringing it into engagement with the log and forcing the latter in a downward direction. When the log emerges from the machine, it may be placed, on the table 111 and cut by the saw 115 into sections of the desired length, and, if necessary, the sections of certain logs may be placed in the supplemental peeling mechanism in order to further remove the bark therefrom.

Changes within the scope of the appended claims may be made in the form and proportion of some of the parts while their essential features are retained and the spirit of the invention is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.
