Application tiled May El,

tina` oi the breastcurve in the front portions of tlaebeels.` rllhis operation takes place immediately after the sawing ot the rough block, and before the turning of the lateral curved surface.

The grooviiig operation hasheretoiore been performed by placing the blank in a holder and traversing the holder b y hand Vover a. cutter arranged to torni the proper curve. lt has been proposed to perform the .operation automatically by feeding the holding1` instrumentality operating in con il nection With a carrier to support the blanks positively and effectively against the tool pressure. Advantageously the blank is auto- `matically gaged on the carrier 4in proper relation to-the tools betoreit is engaged by the jack, and still another important feature of the invention consists in the arrangement of the acking instrumentality to grasp lthe blank. The `forces applied to the blank during jacking and unjacking are thus varied slowly and disturbance of the blank on the carrier is avoided.

The rolling' jacking and unjacking action `above described is advantageous Jfrom an other point of view. There is, as will be seen,inore than one tool necessary to effect the proper grooving operation, and it has been found that a device which holds the i blank jacked continuously While passing1 all the tools gives trouble in operationz` ii it is to move with the blank, it must be mechanii, fr fr a f MitEESAGEE'SIETTEE, A CORFORATNUF seriai no. sienes.

cally complicated. and if it does not move with the blank much friction is generated. By the present inventiomthe blank is jacked only 'when in engagement with a tool, and as stated, the j tickingand unjackingare done so gradually as not to disturb the tion or the blank on the carrier. j

The invention also provides an improved gaged posi- `device for removingl linished Work from the machine, a ieature of Which is an adjustment to follow gaging, movements ot the carrier in order to preserve the operative relation between them. j i

These and other teatures ot the invention comprising certain combinations and ar rangements of parts will be understood from the following description ot a preferred enibodiinent thereof selected tor purposes et illustration and sliovvn in the accompanying drawings in Which,` 1

The main trame l0 ot the machinecarries detachable brackets l2 and l/l in which are mounted `iii anyconvenient manner electric motors 1G. 1'2" with vertical. spindles 18, 19

carrying` at their upper fende the finishing and roup'hingcuttersQO and QQ, respectively. "lhe spindles ot these motors, as

shown.` are in a vertical plane parallel to an endless belt carrier 24 which is traversed pastthem in the direction oi? the arrow in Fig; l over the sprocket Wheels 26, 28, which are driven in anyappropriate manner. A third sliait 30 having;` a Wabble-saw at its upper end is driven by a direct connected motor Se, the Whole construction being' pive ol'ed at in the bottom ot the main trame to permit adjustment. The upper endet' the sbatt has bearings in a plate 38 mounted to slide in guide d() on the trame l0 and adjustable therein by means oft a screw and bolts del. This adjustment moves the saw toward and from the endless belt carrier about the pivot 36 in orderto page aantonen 'ro stier-nn porri i arranged `to correspond approximately to `the centers of the cutting` strokes ol the "from accidental displacement on the endless belt carrier and they pass under the jack Wheel 104 Without disturbance.

i Theteeth ot these jack wheels are spaced suihciently close together so that at least one ot them `will certainly strike a Work blockin any position upon the endless belt carrier and they are set so low in the slides that a substantial compression of the springs is effected so that the work blocks are held very firmly. f

It vvill be observed that the large diameters of the idler Wheels as compared with the dimensions of the wood heel blocks `ejive them a longarc of contact with the blocks and enable them to hold the blocks irmly during` the entire time that the cutters are operate ing on them. i

After passing the second cutter which is arranged to remove perhaps one-eighth inch of stock, the 3vvork blocks pass out to the lett infFig. 1 and are removed trom the carrier by anarm 124.` This arm is pivoted upon a horizontalpivot in a block 128 having a cylindrical portionl` mounted for vertical movement in a plate 182 and held by a set screw` 134 which engages a peripheral notch in the `cylindrical portion 180. the notch beine-` ot considerably greater Width than the thickness of the screw so that the cylindrical portion 130 can move up and down in its holein the plate 182. A pin 136 is mounted upon the lett hand end of the plate 58, and supports the rear end ot the member 124. This pin is of such length that as the plate 58 is adjusted up and down, it

will raisethe rear end of the member 124 to a sutlicient height to permit the passage ot the partitions 54 under it, thisvertical adiustniient of the member 124 beingperj mitted by movement ot the stud 130 in its hole. The finished Work blocks as they come oli' at the left strike the slantine1 edge 138 of the member 124 and are pushed oil the carrier into a conveniently situated barrel.

The partitions 54 Will always be oi such height as to permit the upward projection oi any Work block beyond their tops. In case any Work block passes under the momber 124 'for any reason, the member 124 can tilt upwardly around the end` ot the pin 136 and the block Will be carried around toits outer end 140 and drop on the floor. This upward movement is steadied by the engagement ot a iin 142 mounted upon the member 124 Witha corresponding-ly upwardly ei:-`

tending;` iin 144 on the member 132, a pin and slot guide at 146 being provided. A spring 148 extending between the block 128 and the member 132 holds the member 124 `in its lon'ermost position in contact with the upper ends ot the partitions 54. lhe mein-- "ber 182 is pivotcd at 150 to permit horizontal movement upon the table 152 upon,

which it rests. rihis movement is guided by a pin,` and. slot arrangement at 154 and the member 132 is held. in the position shown in Fig. 2 by a spring 156. Thus in case a block becomes jannned against the tace 188 in some r' `way both plates 188 and 132 vvill swing toward the bottom olr Fig; 2v around the pivot 150, allowingr the block to be carried over the wheel 126 and dropped upon the floor. j

In operation, the attendant puts the blocks 68 into the pockets on the links as rapidly as they come up on the Wheel 28. `They are carried against the arm i() and pressed` against the gage 50. They then pass under the hoiding' member 88 which scores, their tops and holds them against the `pressure ot the saw 32 Which trims ofi' the lip at the breast. They then pass from under the member 88. under the jack Wheel 102 which has been suitablyv adjusted in vertical and horizontal directions and which holds them iirinly against the pressure of' the roughinig cutter v22. They then pass from under this Wheel and shoe across tothe similarly ad jnsted Wheel 104 which holds them likewise against the pressure of the finishing' cutter 20, after which they pass to the knock-ott erm 124 and fall into the receptacle arranged to receive the1n.`
