The sides of the pocket are preferably formed of rollers vertically and pivotally mounted in the beams 37 and 38, so that there can be no'bin ding of any logs'in' so far as the sides are concerned, but this is not usually considered a necessity, though it materially aids in the operation-under some conditions.
In Figures 3 and 4 a number of pivoted and otherwise stationary cam agitators 47 ;'are shown in successive arrangement, particularly to illustrate their use=with the top chains 48, which restrict the entrancelt) to the pocket 50, and the-exitSlinsaidpocket, as well. as assist the cams 47 in their work in disturbing the logs and rollingthem' about into'rubbing' engagement with one another for'the purpose of strippingcthe'bark. I
In .Fi gure 'ithesame pocket illustrated in Figures?) and 4 is shown with the.roller. sides nalled in top and bottombeams as mentioned in the foregoingQbut in thislparticular casetit is shown in connection with the chains restricting the sides oflthe entrance and oflthe exit, and while there'is'not agreatdeal of differencein the use oftherollers in'this form of the invention and what has been mentioned before, the particular form of'S-shaped-cam insuccessive arrangement in a pocket with the guarding. chains on'theroller sides is extremely eflicient. p
In Figures 6 andi'l'the samefornr of chains and. cams'are shown, butin a different ar rangement, whereby difierent sets'of chains are in one section and "different sets of chains are inanothersection, 'andthese incline to wards one anotheras indicated by the numerals53 and 54-, the Lentrance'at one end, which is .in the' form 'ofan inclined way.55, and. the exit atithe other "end, which is in the forin of .an upwardly Linclined way 56,
leading tocthe runway 57 'This all'follows onin the same way as fully described'in' the details, but the usual form of pocket inthis invention has been discarded and the logs are just simply dumped on to the'plat'form with agitators projecting therefrom'or on to the agitators themselves forming thebottoin, The-consequence of this is that the bark isstrip'ped off and carried away,
simply from the excess of logs in' the area of,
agitation.
In Figure 9 the only'point of novelty is the rotating memberwith several cams projecting therefrom, all these cams having the receding faces 59 and extending at intervals fronrthe-rotor 60,which is suitably driven.
This cam member is shown in the end wall of a pocket and may be used in any form of this invention or in any other invention in the same class.
In the operation of this invention, the logs in any of the forms are fed either directly on to the agitators or on to a bottom through which the agitators project. These agitators in the one instance are the cams drawn by chains and in another case they are the actual sprockets forcing up the chains, while in another case they are a successive arrangement of cams,'but this later idea-is'not altogether new, except in connection with features alreadyeXpl-ained, such as the guarding top chains. These top chains "form a very important feature in several forms of the invention as well as the side rollers, which may be applied in'anytfornrof the invention whatu out to the disturbingelements.
"l lhat I claim is 1., In alogbaflzer, means for supporting logs in a pile andmeans forcreating'a'runlning wave in contact withthe pile'and thereby cause asuccession of upheavals.
2. "In a log'barkerya succession 'of oamshaped members adapted to' reach into a pile of logs and tumble them around and *at'the same" time propel the logs forwardly through the association of saidmembers with-rotary members suitabl driven.
