A series of rods 40 are mounted within this strip 39 and are adapted to slide therein, all of the rods being fastened at their lower ends to a presser foot 41 which is disposed above the channeled bar 27 and extends for a greater portion of the length thereof. The ends of this presser foot are rounded so that the foot will easily ride upon any objects inserted thereunder and coiled springs 42 einbrace the rods 40 and bear at their ends against strip 39 and foot 41 so .as to hold the foot normally pressed downward as fai' as it will go. A guard strip 43 is disposed longitudinally upon the frame and between the channeled bar 27 and shaft 15 and is supported in any suitable manner as by means of cross strips 44 which connect the lower portions of arnis 3S with the bar 27. This strip 43 extends overa circular saw 45 which is secured to and rotates with shaft 15. Adjustable bearings 46 and 47 are arranged on the rail 10 andarni 25y respectively and mounted within them is a shaft 48 having a circular saw 49 at one end which rests close to the channeled bar 27 and projects a slight distance thereabove-' Another circular saw 5l) is secured to said shaft at a point removed a desired distance from the saw49 and a pulley 51 is arranged on the shaft 48. A bracket 52 extends forward froi'n the upright 7.

All of the foregoing description applies equally to the two fraines A and B. The frame another arin 53 and in the arms 52 of the two frames and arrn 53 is journaled a drive shaft 54 carrying pulleys 55 adapted to receive power from any suitable source. Two pulleys 56 and 57 -are keyed to the shaft 54 in front of each of the frames A and B and a belt 58 extends around the pulley 56h-nd the pulley 51 on shaft 48. A belt 59 is arranged on pulley 57 and is partly twisted so as to extend around the `flanged pulley 2O on shaft 15. Ears (S0-extends forward from the uprights 6 and S of the franieB and constitute bearings for a shaft 61 having a large pulley 62 at one end on which is arranged a belt 63 which is crossed and extends around a sinall pulley 64 on the drive shaft 54. Shaft 61 has 66 extending around a large sprocket 67 secured to one end of'the shaft 36 which is l fouriia'ed in a bearing 68 as wellas in the l bearings 34 hereinbefore referred to. The l upriglits 5, 7, 8 and 9 of the frame A are ad- ,l justably secured to the slo'tted plates 64 by l means of clamping bolts 69 and all of the E parts on thefiaine A which are disposed on shafts so that the frame A can lie adjusted toward or away from the' frame B in, order to adapt the machine for cutting slats of diff ferent lengths. lt is of course uiiderstoodl l the shafts 36 and 54 are feathered on said l that the frame B is ,iixedly connected to plates l and 2.

ln using the machine the shaft 54 is driven'.y in the direction of the arrows indicated there?1i on and rotary motion will be transmitted to 'in the endless chains 32 through the belt 63 and .i pulley 62 to the chain 66 which rotates the shaft 35 and the sprockets 35 thereon. The lugs 37 projecting from the chain will thus be moved in unison frointhe front to the rear ends of the channeled bars 27.. The saws 45 will he rotated in the directions of the arrows by the belts 59 andthe two saws 49 and 50 onl each shaft 48 will be rotated in the directionall of the arrows thereon by the belts 58'. VA long strip of wood is placed by the operatorl across the ,teeth of the chains 82 where'they enter the channels in strips 27 and the adn joining lugs on the chain will conie up against the strip and pull it forward under the presser 85 feet 41 and thence into contact with the saws 49 and 50. Saws 5() will cut ol'l a slat 70 from the strip and the small saws 4) will at the saine time cut into a slat at a predetermined distance from the ends thereof to form 9o.

shoulders 71. The slat will. continue in its forward movement with the chains 32 and' under the presser teet 41 until brought into -contact with the horizontally arranged saws 45 which will cut longitudinally into the ends 95 of the slat a sufficient distance to ineet the incisioiriiut by the saws 49 and therefore a tenen 72 will be produced which will be of the proportions desired. lt is to be understood that one slat can be placed between every roo two lugs 37 on each chain and therefore several slats niay be caused to travel through the machine simultaneously and so that they will'be successively operated upon by the saws. By nieans offa iiiacliiiic such as herein io'5 described a large num ber of slats can be providedwith tenons in a very slioit period and the cuts will be accurate and smooth. The presser feet 41 serve to prevent the slats from sliding or becoming displaced during the cuti io` tino' o erations and will automziticallv ado .P y

just themselves to slats of dillcrent tliicl nesses. By loosening tlie belts 5S) tliol'ran'ie A can be slid from oi' toward the frame B iii order that slats of desired lengths can be cut. i i5 The idlers 31 are sufficiently heavy to keep 'the chain 32 tight under all conditions.

The preferred form of the invention has been set forth in the foregoing description but l do not limit myself thereto as l ain izo aware that modifications may be made therein without departing from 'the spirit or sacriticing the advantages therein, and l therefore reservo .t he rightto make suc-li changes las upon the adoining portions of the frainesfan 13o fairly fall within the scope-of the invention. 125
