invention relates to log handling deices and has for an object the provision of 'ineans which inay be positioned between the head blocks of a mill icarriage to load logs therein so thatthe' latter maybe acted upon by the saw, the construction being such that the logm be canted'or turned to present a diflferentface'tosawp I 1 [Another object of the iniiention is the pro- Vision of a log canting gear of novel construction, which may be readily operated to load and turn logs and which provides a necha- 'n ism for the i above purpose: that is positive and reliable in construction and operation, and may begeasily. applied to a'lnill-carriage.
'With the above and other object'sjin View;

Figure 3 is a section on theline 3+3 of Figure 1 with the log-turnlng position of the,
mechanism shownby dotted lines.
Figure 4 is a detail perspective iew of the Figure 5 is a sectional View on the line 5+5 ofFigure 3. l f
Figure 6 isa fragmentary longitudinal section taken longitudinally through adjacent ends of the arm sections with sections shown in separated relation. r Referring to the drawings in detail whereln'llke characters'of reference denote corresponding partsthe reference character '10 indicates parallel sills ofa mill carriage .7 which is movably'supported upon wheels 11 which travel over tracks 12, the carriage beingdesigned to support logsas' indicated I at 13. The carriage includes spaced head blocks 14 from which rise theusualknees15. The log handling niechanisrn'is designed to ,be positioned between apair of head blocks ll and while-only one pair is shown, the number o'fhead blocks be increased, in which case the mechanism will be arranged between adjacent blocks I I Rising. from one or" the sills 10 are spaced bearings l6'which rotatably support asha'ft .17, while' rotatable upon this shaft between spaced collars18 is a sprocket 19. This sprocket is housedwithin one end. of one sectien 20 of an arnr21, the othersection 22 of which is pivctally secured tothesectiOnEZO as shown at '23. ThesectionsQOand of the. arm 21' are transversely ,c'h'annebshaped "and the sprocket .19 is housed between the -i 'wall ofthe section 20 at the}innerend of the arm. "The'shaft 17 passes through the e H section 20 oft-he arn 21 so "thatahousingis providedi'for 'the sprocket .19.; The section 22 of thearrn 2lfis' providedwith a lugjl 22, & ,andjthe adjacent end of'the sefctioiiQO is 3' squared as at QOjto engage this lug andli nit relative pivotal rnoveinentoi the arm sect on's. in one direction;

. In order to eifect this operation,the"shaft 28 uponwhich the sprocket 25 is mounted,'
has pivotally secured thereto the inner ;end

Thistrack '31 isfcarried by a 592 11133 which connects the sillslO. Pivotally secured tothel'ower ends ofth'e legs 29 are the outerbifurcated ends of a bar 33." This bar is illustrated "in detail in' Figure 4 of the drawings andits intermediate portion is bent as at 34 to provide an offset end 35 having a longitudinally disposed slot 36. This slot receives the shaft'jl'? and is slidable upon a bushing or collar 37 upon the shaft.- The bar 33 thus be moved longitudinally along the track 31. Then the bar is movedoutward to cause the roller 30 to ride upward 'uponthe inclined section 32 of the track, the outer end of the arm- 21 will be raised to the position shown in Figure 2 of the drawings, which is the log holding position of the mechanism.
When the bar 33 is moved in an oppositedirection, or to the position shown by the dotted lines in Figure 3, the sections 20 and 22 of the arm 21 will be moved relatively upon the pivot 23 so that the intermediate portion of the arm 21 will be raised to bring the chain 24 7 into engagement with the log: Upward movement in this position is limitedby stops 38 which extend downward from the adjacent ends of the arm sections 20 and 22, while va roller 39 acts to prevent the chain from dropping at this point. This; roller may be suitably grooved to permit of the passage of'the teeth 27 of the chain 24. 1 r I Various means may be utilized to impart movement to the bar 33, the means shown consisting of a pressure cylinder 41 within which operates a piston (not shown). A rod 42 which is connected to the piston and extends from the cylinder has its outer end'suitably connected with the-adj acent end of the bar 33.
The chain 24 may also be driven from any suitable source, the meansshown consisting of a motor 43 which hasa Vpitman connection as log engaging element movable along the arm, and means'to move said element.
3. In a log canting gear, a sectional arm, means pivotally connecting adjacent ends of said sections, means to pivotally mount one 7 end of the arm, a track located below'the arm,
an elevated section at one end of the track, a leg having one end pivotally secured to the other end of the arm and movable along the track, means to, force the leg in one direction to engage the elevated section of'the track and move the end of the arm pivotally upward, or to move said leg in an opposite direction to force the sections upward at their point of pivotal connection, a log engaging element movable along thearm, and means to move said element.
4. Ina log canting gear, a drive shaft,
means to operate the shaft, a sectional'arm 7 having one end pivotally mounted upon the shaft, meanspivotally connecting the arm sections,a track below the arm, anupwardly inclined section in said track, means movably secured to'the outer end ofthe arm and engaging the track to support the end of the arm, a'bar having a longitudinally disposed slot in one end to receive the shaft and having its opposite end connected 7 with the leg, wherebythe latter may be moved in'opposite directions to elevate the outer end, or themtermediate portion of the sectional arm, means to move the bar and movable means carried by. the arm and operatively connected with the shaft to engage the log. v
