The inner sides oft e cross-heads'e2 and e are`preferably curved or segmental in form and are rovided with teeth'i, and the operation wil vbe readily understood from .the foregoin T description,I when' taken in connection' with the accompanying 'drawings and the'following statement thereof: AIn ligs.` 1

and in practice thev separate .arts of the main frame are.disconnected anj adjustedon the ytI-'u'nk of the tree,as indicated' in Fig'. 1,

and the cross-head1; is forced inwardly,A so

^ that thetrunk ofthe tree. will'be securely vgrasped and held on the opposite sides thereof. The bearingsor supports 'of the'sawsf of the main frame are then adjusted so as to cause said saws to bear on' the opposite sides of the tree, and the cross-head d is then operated.v vThis operationof the cross-head d gives the saws in the mainframe'V ay longitudinal movement-and also a rotary 'movement, the rotary movement being accomvthenl fall in the plished by means of the screws da whenlthey pass through the nuts b4, and this rotary movement is, as will be understood, an intermittent movement in opposite directions.r

At ,the same time with"\the construction shown in the drawings water is admitted to 'the saws or combination saws and raspsthrough the tubes f 4, and the cuts-in the tree are kept clean and the sawsvare kept cool.

` It will lbe understood that the saws f 'may be forced inwardly gradually as the cut-ting` a proceeds by means ofthe s crewsdjandfei,

My invention is also not limited to the use of the arm g and the arts connected therewith'as herein desc-rined, and other' means may be employed for cutting tlre slots j" and in the trunk of the tree.

The arm g or the head thereof is provided i with a handle m, by which it may be swung into different positions, and in practice said y arm or the free end thereof may also be provided with any suitable support on which the free end or" said arm may travel. It will be understood that in practice. the arm g is made of Considerable Weight, and a suitable support for the h'ee end thereof will be necessary. y
