Idaho ApplicationNove'mber 28, 1952, serial Nol'szaoe j This invention relates to a power tool and more"'particularly 'to a portable log peeler for disbark'ing or peeling timber.

The primary object is to' provide an improved logpeeling machine which is easily transportable in "'a forest to the locations where it is desired to peer the bark from logs. I

further-object of this invention is to provide a portable log peelerthat is comparativelylight in' Weightso as to enable such to be readily carri'e'd'and operated in a convenient manner.

The eonstruction of this invention features the a prime1mover todrive an eccentric which "ea sfes'a' reciprocation of a blade assembly slidably mounted on ia' frame. It is tobe noted thatthe prime mover is resiliently mounted on aframe-so as" to increase the durability of the d evice while preventing internal damage to working parts- Still furtherobject's of theinvention reside in the provision of a portable log peeler that is ir-e s su t bl hi hly. ef icientnn perati n, im e in soestru t onand an f c t o free; and which is comparatively inexpensive to produce.

'I'hose', together with the various ancillary objects of the invention which will becom'apparent as the following description proceeds, are obtained by this portable log peeler, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

'3 Claims. (01. 1114-208) Figure 1 is a side elevational View of the portable log peeler comprising the present invention;

Figure 2 is a bottom plan view of the invention showing the relative positioning of the various elements of the frame and base in greatest detail;

Figure 3 is a side elevational view similar to that shown in Figure l, with parts thereof being broken away to show other parts in section for greatest detail;

Figure 4 is a perspective view of the base and frame members, showing in detail how the various elements may be adjusted relative to each other;

Figure 5 is a perspective view showing the construction of the blade assembly; and

Figure 6 is a sectional view as taken along the plane of line 6--6 in Figure 3.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral [0 indicates an arcuate base panel which is concave downwardly and which is provided with'side members l2"and. l4. Avv frame including leg members it and I8 is providedandthese members it and it are interconnected'at the rearend'by a cross memberZll. Projections 22 and 24'ar'eflformed integrally with the leg members It and i8 and'slots 26 and 28 are formed in the projections and extend downwardly into the sideframe members it and !8 respectively. Bolt fastjenersitilandfi pivotally mount the leg members ilian'd E8 on thejside members [2 and M of the base {0.

Guides

34 and 36 are'provided and are pivoted at their outer ends to the 'legfmembers l6 and I8 by means of bolt fasteners 38' and 40, and adjustablysecured at their inner ends by

fasteners

42 and 54 whichextend through t'he slots 25 and 28. Carriedby the base it! is a rod G6 which is threaded at" its upper end as at l8. Therod 46 extends through an aperture in a plate 50 which is provided for securing aprime. mover 52 to the frame; The plate .lifl'is heldjin position by means of nut 53 The other end of the plate 50 is held in'position by a fastenergjit which also holds plate 56 which extends over .a portion .of the prime mover "52. Another fastener 58 is pro vided for holding the other end of the plate,56 imposition; fipacedlugs; 60 and 62 support the plate tifiin'spacedrelationship to formanopening for the bottom portion of the prime mover 52. A coil spring 64 coaxial with the rod 46 biases the plate 50 away from the base it. This coil spring 64 forms a resilient mounting for the prime mover 52.

The prime member 52 is designed of such size and rating as to readily enable the device to adequately perform its functions while being relatively light in weight. The prime mover 52 drives a shaft 86 which is keyed to an eccentric 68. The eccentric 68 rides in a bearing ring H] which is mounted within a casing 72 having a crank arm 14 integrally formed therewith. A suitable Zerk or grease fitting i6 is provided to insure freedom of movement of the various elements. Secured to the crank arm M is one section 78 of an adjustable rod which includes a turn-buckle Bil for adjusting the size thereof. The other section 82 of the rod is secured to a rocker arm 84 mounted on a shaft it which is carried by ears 88 and 9t secured to an arcuate mounting plate 92. A suitable grease fitting 5A is provided for lubricating the rocker arm and cotter keys as at 96 hold the shaft 86 in position. An arcuate angularly extending guard 98 is provided and a blade it together with the guard 98 is secured to the member 92 by means of bolts such as I02. The blade I is adapted to slide within grooves I04 and I08 formed in the

guides

34 and 36. Handles I 08 and H0 are provided for holding and operating the portable log peeler. In operation, with the shaft 66 actuated by the prime mover 52, the eccentric 08 will cause movement Of the bearing I0 and hence a reciprocating movement for the casing I2 and the crank arm I4. This in turn will actuate the connecting

rod sections

18 and 82 to reciprocate the entire blade assembly within the slots I04 and I06 of the

uides

34 and 36. As can be readily understood, the cutting angle of the blade I00 may be changed by adjusting the position of the guides by means of the

nuts

42 and 44. A tie rod II2 for rigidifying the structure has locknuts H4 and H5 for holding the frame members I6 and I8 in spaced relationship.

Since from the foregoing, the construction and advantages of the portable log peeler are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.

What is claimed as new is as follows:

1. A portable bark peeler comprising a base, a substantially U-shaped frame including a pair of spaced leg members and a rear cross member, means pivotally securing said leg members to said base, a prime mover carried by said frame, said prime mover driving a shaft, an eccentric on said shaft, spaced guides adjustably secured to said leg members, grooves in said guides, a blade assembly slidably mounted in said grooves, and means operatively connecting said eccentric to said blade assembly, said prime mover being resiliently mounted relative to said base by a spring biasing said rear cross member away from said base.
