PULP-Woon PEELER.

Application led June l5, 1924. Serial No. 718,053.

To all whom, 'it may concern.'

Be it known that I, JonN SArnoNEs, a citizen of Greece, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Pulp-food Peelers, of which the following is a specification.

This invention relates to new and useful improvements in pulp wood peelers.

An important object of the invention is to provide apparatus which is capable of peeling ofi' the bark from pulp wood or other kinds of logs.

A further object of the invention is to provide a peeler which will cut uniform strips from logs irrespective of the diameter of the same. .i

A still further object of the invention is to provide means for mechanically feeding logs through the peeling portion of the apparatus and for centering the logs whiley traveling through such peeling portion.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed for designating like parts throughout the same,

Figure 1 is an elevational view of the entire apparatus embodying this invention and villustrates a pair of logs being treated there- Figure 2 is a top plan view paratus illustrated in Fig. 1, I

Figure 3 is a detail elevational view of one set of peeling elements with the remaining sets o peeling elements illustrated in dotted lines to properly disclose the relative arrangement of all of said elements,

Figure 4 is a detail perspective View of one cutting element with its tensioning spring and guide,

Figu detail elevational View of the of the apre 5 is a cutting elements illustrated in Fig. 1 and shows in longitudiinal section a log being operated upon by said cutting element, and

Figure 6 is a fragmentary elevational view of the feeding conveyor employed for moving logs through the peeling portion of the apparatus.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of thisinvention, the numeral 5 designates the side bars of a base frame which is employed for supporting the apparatus and is retained in an elevated position in respect to the ground by the legs 6. A desirable number ofv cross braces 7 are provided for keeping these side bars 5 in fixed relation with respect to each other and for strengthening the base frame.

Carried'by the receiving end of the base frame is a trough 8 which is of substantially V-shape and is formed of the perpendicularlylextending braces 9 to which are secured the longitudinally extending boards 10. The discharge end of the base frame is also provided with a substantially V-shaped trough which is formed of the braces 11 and boards 12.

Suitably supported adjacent the receiving end of the base frame is a transversely extending horizontalshaft 13 which carries a roller 14. Snitably journaled upon the base frame in prokimity to the outer ends of thel boards 10 is a transverse shaft 15 carrying a roller `16. Mounted upon these rollers 14 and 16 is an endless belt 17, best illustrated in Fig. G. rlhis belt 17 is provided with a plurality of transversely extending, pivotally mounted bars 18 having sharpened edges 18a. Suitably keyed to the shaft 15 is a pulley wheel 19 which carries the belt 2() that rides upon the pulley wheel 21 carried by the power shaft 22 which is journaled in the bearing Q3 carried by the base frame. It is to `be understood that suitable power is provided for driving this shaft 22 for the purpose of causing the belt 17 with its bars 18 to travel in the direction of the arrow in Fig. 6. This belt 17, with its bars 18, is intended to feed logs L through the apparatus. It is to be understood that these bars 18 are piyotally secured to the belt 17 in such a manner that they will pivot forwardly in the direction of travel of the belt and thatthey are prevented, by any suitable means, from pivoting rearwardly in the opposite direction of the travel of the belt. As' a log L is started onto this belt 17, the bars 18 positioned between the ends of the log will pivot forwardly for causing their ioo sharpened edges 18l to engage the outer surface of the belt, thebars not being able to support the weight of a, log. These bars will be pivoted forwardly until the rear end of 'the log passes onto the belt whereupon the Vnext bar .18 passing'around the roller 14- will be placed in engagement lwith the rear j trated in Fig. 3. For the purpose of resuitable end of this log and will be retained in a vertically extending position for feeding the log longitudinally forwardly.

Carried by the boards 10 are a circular series of reversely curved spring arms 24 which are employed for centering the logs L in respect to the cuttingv elements, tol be described at a later point. The transversely extending brace bar -7 positioned adjacent the rear ends of the boards 12, is provided with a perpendicularly extending ring 25 which cooperates with the said brace bar 7 for carrying a4 circular series of spring arms 26 which are adapted for engaging the frontl end of the logs as they are fed out of the central portion of the apparatus onto the endless conveyor belt 27 which is carriedby rollers 28 and 29 mounted on shafts 30 and 31. The shaft 3 0 is provided with a pulley 32 upon which rides .a belt 33 which engages a second pulley 34 ,carried by the shaft 15. It will, therefore, be seen that the conveyor belt 27 travels in unison with the conveyor belt 17.

Suitably secured to the side bars 5 of thej base frame, as by the V-shaped braces 35, are a series of rings 36, 37, 38 and 39 which are concentrically arranged lwith the arms 2 4 and 26. Extending between the rings 36 and 37 and suitably secured thereto are a desired number of longitudinally extending bars 40 which are equi-spaced around the peripheries of the said rings. Extending between the rings 37 and 38 are the equispacedr longitudinally extending bars 41 which are positioned laterally'of the bars 40 or staggered in respect thereto. Extending between the rings 38 and 39` are a third set of longitudinally extending bars 42 which are positioned laterally of the bars 41 in such a manner that they' will be arranged inv staggered` relation with thesebars and also the bars 40. By inspecting Figs. 1, 2 and 3, it will be seen that the rings 36, 37 and 38 are provided with a plurality of pivoted arms 43 which are connected to these rings in longitudinal alinement with the bars 40, 41- and 42 for the purpose ofarranging these arms 43 in staggered relation in respect to each other as best illustaining the outer ends of these arms in proximity to a `log L passing through the rings 36 to 39 inclusive, the arms 43 are each provided With a rod 44 which extendsy through a opening in one of the bars 40, 41 or 42 and as a spring 45 encircling the same and positioned between its arm 43 and the respective bar 440, 41er 42.

In Figs. 4 and 5, an arm 43 is illustrated in detail as having removably attached to its outer end a transverse y extending cutting blade 46 of arcuate shape which is positioned lwith its cutting edge 47 presented to fed longitudinally through' the apparatus toward the discharge end of the base frame, the bark B will be peeled o, as best illustrated in Fig. 5, into longitudinally extending strips which will be of equal length to the length of the log being peeled. vThe arm 43, in Figs. 4 and 5, is also illustrated as being provided with an arcuate guiding blade 48 which is pivotally secured, as at 49, and is clamped in its adjusted position by the. bolt 50 received within an arcuate slot in the said blade 48.

'It is believed thatl the manner of feeding logs through thepeeling portion of this apparatus has been suiciently described heretofore and for this reason the action of the cutting elements 46 will-be described at this point. '-It is intended that only the arms 43 pivotally carried by the rings 37 and 38 be providedwith the guiding blades 48. As a log is passed through the ring 36, and as it approaches the ring 37, the cutting elements 46 carried by the arms 43 pivotally mounted upon this ring 36 will start peeling strips from the saidlog. As the front of the log approaches lthe arms 43 carried by the ring 37, the guiding blades 38 will aline .with one edge of the bark still remaining upon the log and these blades will guide the cutting elements 46 carried by the arms 43 pivotally securedl to the ring 37 so that a second strip Will be cut from the log to the left of each of the irst strips. The 10g will then be fed through the rings 38 and 39 and the cutting elements 46 carried by the arms secured to the ring 38 willcut the remaining strips `of bark from the log2 the blades 48 carried by these last mentioned arms 43 being employed'for guiding the-cutting elements 46. v

It is to be understood that the form of.

this invention herewith shown and described is to be taken as a `preferredexample Vof the same, and that various changes in the shape, size, and arrangement of-parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
