4 Claims.

This invention relates to a log peeling or rossing machine and is an improvement over the structure embodied in my prior Patent No. 2,601,261, issued June 24:, 1952, for Angularly Adjustable Feed Rolls for Log Peeling or Rossing Machine.

An object of this invention is to provide in a log peeling machine an improved means for supporting the flailwhereby logs of irregular shape may be easily debarked or peeled.

Another object of this invention is to provide in a log peeling machine a pair of rockable flail supporting levers, a flail shaft with bearings at eachendof the shaf-tandmeans pivotally mounting the bearings on the forward ends of the levers so that each lever may rock independent of the other lever.

A further object of this invention is to provide a log peeling machine which is of relatively simple construction 50 that the various parts may bemade rugged and strong enough to withstand rough usage. a

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a detailed end elevation of a log peeling machine constructed according to an em- I,

substantially on the line 3-3 of Figure 2,

Figure 4 is a sectional View taken on the line 4-4 of Figure 2,

Figure 5 is a fragmentary sectiona1 view taken on the line 5-5 of Figure 1,

Figure 6 is a fragmentary sectional View taken on the line 6-6 of Figure 3,

Figure '7 is a fragmentary sectional view taken on the line of Figure 5,

Figure 8 is a plan view, partly broken away, showing the flail and support therefor.

Figure 9 is a fragmentary sectional view showing the flail regulating means in locked or servicing position.

Referring to the drawings, the numeral l designates generally a base frame structure which has mounted therein a log rolling and log moving mechanism generally designated as H. The log rolling and moving mechanism II is more specifically shown in my prior patent supra.

The frame ||l has disposed at the rear side thereofupright supports |2 connected across the top by an angle-shaped connecting bar l3. A power member. i4 is carried by the frame l0 and includes a drive shaft |5 having a pulley l6 about which an endless belt engages. The belt IT, as shown in Figure 8, engages about a ulley |8 fixed to a shaft |9' journalled in bearings 2i! which are carried by the upright members I2.

A pair of elongated levers 2| are rockably mounted on the shaft l9 and a flail generally indicated at 22 is fixed to a shaft 23 which is journalled in bearings 24. The bearings 34, as shown in Figures 5 and 7, include an inner member 25 which is angularly movable relative to an outer housing 25, which is secured by fastening means 2'! to a lever 2|. In this manner each lever 2| may rock independently of the other lever so that the chains 29 which form part of the flail 22 may engage logs of irregular conformations.

Each lever 2| has extending from th rear thereof a balance carrying bar 30 on which a weight 3% is adjustably mounted. Each lever at the forward end thereof has secured thereto a downwardly and outwardly projecting guard member 32, and a laterally projecting plate 33 extends from each lever 2|. Lugs 3| depending from plate 33 carry log riding rollers 34.

The shaft |9 also has fixed thereto a pulley 35 for each lever 2| and a belt 36 is trained about the pulley 35 and about a forward pulley 31 mounted one on each end of the flail shaft 23. The two levers 2| engage on the outer sides of a pair of upright guide bars 38 which are fixed at their lower ends to the frame Hi and are secured to the upper rear bar it by means of a triangular brace including a pair of rearwardly convergent bracing bars 39.

Each lever 2| has fixed thereto a depending lever 40 which is connected to an upwardly projecting lever 4| by means of a link 42. The lever 4| is fixed to a shaft 43 journalled in bearings 44 carried by the frame I0, and a hand adjusting lever 45 is fixed to the shaft 43. Forward rocking of hand lever 45 will swing lever 4|! upwardly and forwardly so as to thereby raise the flail carrying levers 2|. Link 42 is formed with an elongated slot 28 through which pivot 46 engages so that each lever 2| may rock upwardly independently of one another.

A dome-shaped guard 41 is disposed above the forward ends of the levers 2| and is supported from outer and

inner brackets

48 and 49 carried by the levers 2|. The guard 4! is yieldably supported relative to the

brackets

48 and 49 by means of springs 5|] which engages about bolts 5| 3 loosely fitting in bolt receiving holes in the

arms

48 and 49.

A downwardly and outwardly inclined guard plate 52 is fixed to the forward portion of the guard 41 for deflecting the loosened bark which is projected outwardly by the flail chains 29.

In the use and operation of this device, the log which engages the toothed rolling and feeding members I I is engaged by the rotating flail chains 29 and the levers 2| are lowered to operative position by rocking the hand lever 45 rearwardly so as to swing levers 40 rearwardly and thereby swing levers 2| downwardly.

In the event the log is uneven as to any portion of the surface thereof, the levers 2! may rock one independently of the other, with shaft 23 rotating at normal speed and the bark on the irregular surfaces of the log will be removed in the normal manner.

When it is desired to servic the flail structure or the log feeding means, this may be done without removing the guard 41 by manually'raising the outer ends of the levers 2| and swinging hand lever 45 rearwardly until lever 4| bears against the rear of frame I!) as shown in Figure 9. In this position lever 4| is locked and link 42 is also locked so that levers 2! will be held in an extreme upper inoperative or servicing position.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. In a log peeling or rossing machine having a frame with means for rotating and moving a log endwise, a flail shaft, a flail member on said shaft, a pair of shaft supporting levers, means rockably supporting said levers from said frame, for independent movement one relative to the other, a bearing for each end of said shaft, and means rockably securing said bearings to said levers.

2. In a log peeling or rossing machine having a. frame with means for rotating and endwis moving a log, a pair of elongated levers rockably carried by said frame, a flail shaft, a bearing on each lever for supporting opposite ends of the flail shaft, means rockably mounting said bearings on said levers for rocking movement of said shaft upon rocking movement of said levers, said flail shaft being rotatable in said bearings, a flail fixed to said shaft, and a dome-shaped guard carried by said levers and extending over said flail.

3. In a log peeling or rossing machine having a frame with means for rotating and endwise moving a log, a pair of elongated levers rockably carried by said frame, a flail shaft, a bearing on each lever for supporting opposite ends of the flail shaft, means rockably mounting said bearings on said levers for rocking movement of said shaft upon rocking movement of said levers, said flail shaft being rotatable in said bearings, a flail fixed to said shaft, a dome-shaped guard carried by said levers and extending over said flail, and downwardly projecting 10g riding bars carried by the free ends of said levers.

4. In a log peeling or rossing machine having a frame with means for rotating and endwise moving a log, a pair of elongated levers rockably carried by said frame, means for manually adjusting said levers, a flail shaft, a bearing on each lever for supporting opposite ends of the flail shaft, means rocka bly mounting said bearings on said levers for rocking movement of said shaft upon rocking movement of said levers, said flail shaft being rotatable in said bearings, a flail fixed to said shaft, and a dome-shaped guard carried by said levers and extending over said flail.
