, The shaft 16 is driven from a main driveshaft 22, which is dis osed longitudinally and mounted in suitable earings upon the upper transverse sup orts orbeams 4b ofthe vertlcal portion 4 of t e frame. VThis shaft may be eared to the shaft 15 in any suitable manner; ut I referably emplo. a pair of friction cone-w eels 23 and 24, t e latter of which is mounted to slide longitudinally upon the shaft 16, but is keyed to rotate therewith, and the former of which is secured upon the shaft 22. The cone-wheel 24 is shifted into and out of e Vagement with the cone-wheel 23 by a clutcllilever 26,. which latter is connected by a link 27 to a foot lever or treadle 28, which is pivotally mountedat 29 upon one of the horizontal cross-beams 2", as shown in Fig. 1 of the drawings. 4A clutch deviceoi any i formr and construction may be substituted for the one just described, since it forms no part of my invention. It will be seen that when the free end of the treadle 28 is depressed the chxtehslefver 26A will be operated to shift the const-Wheel 24 against the tension of its act'ati s ring into frictional engagement wit t e cone-wheel 23,. so that the-latter will rotate the Wheel 24, and hence the shaft 16. Upon the shaft 22 is secured a main drivefpulley 3U, which may be driven from any suitable source of power.

Pivotally mounted upon the shaft 22, so as to swing transversely,` is a frame 31, upon which the saw 32 is mounted. This frame 3l is of rectangular form, consisting of side beams connected by cross and diagonal bars and having et their ends. hangers and beerings 33 34. The hangers. 33 receive the shaft 22, and the bearings 34 receive a shaft or spindle 35, which has the saw 32 secured upon its forward end. The shaft 35 is driven from the shaft 22 by a belt or band 36, which passes around pulleys 37 of the same diameter, secured upon said shafts, as clearly shownin Fig. 1. The saw 32 is of circular form andis adapted to travel through transverse kerfs. or slots 38 in the longitudinal beams 2 of the horizontal portion 2 of the main frame when the frame 31 is swung In order to rmit the log Il or any other work to be saw d into blocks or pieces off the samellength I provide at the forward ,end of the horizontal portion 2 of the frame or su port a station' transverselywmging head-block or

sto

4,1 This stationary stop 40 is/slidabl and) adjustably mounted upon a longitmneliy-extendingbeam or bar 43, which is arranged in' l longitudinal alinement with one of the 'side beams 2" of the horizontal portion 2 of the freine and has its outer orforward end supported by an upright 43. The statiom headbloek or stop 40 anl a seams ary stop 40 is in the form of an arm which extends transversely and is formed upon a uide 42, which engages and slides upon theeam 43. In this guide 42 are formed upper and lower apertures `which are adapted to aline with upper and lower rows of apertures 45, formed in the beam 43. are arranged in a staggered or zi zag relation, so that a locking-pin 44 ma e passed through one of the openings in t e guide42 and one of the openings 45 to permit the stationary sto 40 to be secured in an adjusted position. his construction ermite the sta-` tionary stop40 to be adjuste at any desired distance from the saw.

The swinging stop 41 is adapted toswing transversely and close to the rear or inner face of the stationary stop 40, the thickness of the swingi stop 41 being such that the blocks or sawe -oil ortions of the l willbe permitted to read dro chute or conveyor a ter said swinging stop 41 is swung upwardly from between the stationary sto 40 and the end of the block or eut portion o the log. The sw ing stop 4I is adapted to be in longitudina ahnement with the center of the log-feeding means when the saw 32 isswun to one side and the lo is ied up against sai stop, and it is adapted to be `automatically swung from betweeuthe end of the log and the stationar stop 4i) as the saw cutsitswa through t e lo The rey moval of the swinging stop 41 in t is manner permits the block or cut portion of the log to readily drop as it issevered. If this space is not provided to permit the block to readily dro it wed es between the stop and the saw or t e end o the remaining portion of the log .and will not drop into the discharge-conveyer 5-2. The stationary stop 40 serves both to. guide the swinging sto 41 and to assist it in resisting the forwar thrust of the log. The Swingin stop 41 consists of an arm formed or sec-ure upon a. sleeve or casting 43', which slides upon a shaft 42 and may be secured in an adjustable position thereon b a set-screw or other suitable means 44. will be understood that the swinging stop 41 must be adjusted Whenever the stationary stop 40 is adjusted, so that the former swings close to the latter, and it will also be understood that the stationary stop 40 is adjusted according to the length of the blocks or sections into which the log or work is to be out. The swin ing sto 41 is operated automatically by t e sawame 31 by s Vurng upon the shaft 42 a crank 45', whie is connected by a link or rod 46 to one end of a. doublev crankshaft 48 mounted insuitablebea t upon one of the uprights 4v ofthe vertical portion 4 of the mam frame. 'The other 1rcrank 49 of the double-crank shaft is connested by a. link or rod 50 'toa bracket 51, which is connected to the frame 31. It will be seen that when the latter is swung tran These apertures into a discharge in said stop and beam to adjustably secure the former upon the latter, a longitudinallyextending shaft, a transversely-swinging stop slidably and adjustabl)r secured upon said shaft and adapted to swmg in close proximity to said stationary sto a crank upon said shaft, a double-crank s aft upon sald frame and connections between the cranks of sai double-crank shaft, the crank u on said 1ongitudinally-extendmg shaft an said transro versely-swinging saW-carryi frame, substantially as shown and descri ed.
