Application filed August 31, 1921. Serial No; 4 7,256.

T all whom it may concern.

Be it known that I; ERLE G. AsHLnY, a citizen of the United States, residing at Memphis, in the county of Shelby and State 6 of Tennessee, have invented certain new and useful Improvements in lVoodworking Machinery, of which the following is a: specification.

My said invention relates to an improvea v prevent the. board frombending away from ment in woodworking machinery in which a plurality of blocks of wood may be operated on simultaneously and. each block or board as it passes through the machine may have its edges evened, its sides planed and 16 grooved and finally be sawed apart to form strips such as are used for battery separators. It will be understood that the number and kind of operations may be varied by making obvious changes in the machine.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, a

Figure 1 shows a plan of my improved machine, I

Figure 2 an end view thereof, and Figure 3 a detail of the driving gearing.

In the drawings reference character 1Ov indicates a frame for supporting VZUCIOUS parts of the machine. In a lateral exten sion of the frame is journaled a shaft supporting at its ends two circular. saws 11 and 12. The shaft as here shown is driven by a motor 13. The upper part of the frame is provided with aset of guide and driving rollers 17 arranged in pairs at each end.

Each set of rollers serves to guide a board or a strip of lumber 18 toward the corre sponding saw. The rollers are held in close engagement with the board bymeans of springs 19 provided with. adjusting screws 20 for varying their tension.

At each side of eachboard there is a revolving head 21 and each head may be pro- 'vided with knives for planing and corrugating the adjacent face of the board and with horizontal knives for trimming the upper and lower edges as described in'co pending application No. 497,255 of even date herewith. v

Each revolving head is provided with a guard 22, the guard extending around the head and forward and rearward over the rollers and acting as a housing and bearing support for the rollers. The guards also 'extend forward adjacent thefsaws and I i ew armeserve to'some extent as guards therefor, at. the sametlme serving effectivelyto gu1de the boards to thecorresponding saws and preventlng' bendmg or" s1dew1se movement of the boards. Directly opposite the later acting head of each set is a plate 23 Can I "ried by the corresponding guide and adjust 1 able towardtheboardiby set screws '24 "to the opposed head whereby it might failto be properly trimmedq '1 f I have shown the front set jof rollscon nected to afcommon driving shaft 25. and the rear set to acommon driving shaft '26, the shafts being driven by a common chain 27. passing over sprocket gears thereon and I i i a chain 28 in turn connected to the rear shaft and to a motor 29 for driving the .7 i pair of beveled gears 30 and 31 engaging i latter. The shaft 25 has at each end a corresponding gears on the rollers IZand the shaft 26 is similarly connected to the rear pair ofrollers. 1 The bevel gears on shafts 25'and 26 are splined to the shafts and movable endwis e thereof to permit ad ustment of rollers 17. Each rotaryhead'p is preferably driven by a separate motor as shown at 32 and 33." I

It will be obvious to those skilled in the{ art that machine may: be modifiedpinvarious ways without departing from the spirit of the invention or the scopeof the appended claims.

Having thus fully describedmjy saidinvention, what I claimfas new .and desireto' secure by Letters Patent, is:

1. In a woodworking machine, a plurality of cutterheads arranged in opposed pairsf f individual driving means for the cutter heads, a plurality of spring-pressed feed rollers for feeding a strip of wood to each cutter-head, a. saw "in advanceof each pair j of cutter-heads and lying in a plane passing v y between them, aplurality of spring-pressed feed rollers acting on each strip'between the cutter-heads and the saw, and common driving means for all said feed rollers, substanl tiallyas set forth. a 1 v 2. In a machine for making battery sep-v heads arranged with one in advance'of the other and carrying grooving and planing 1105 I arators, a pair of opposed rotary cuttermeans, a pair of feed rollers in front of each cutter head, a guard for each cutter-head comprising parts resting against the work :and transversely slotted end extensions,

bearings for the feed rollers movably supported in the slots, springs acting on said hearings to force the feed rollers toward the work, one of said guards hav ng a re- ,ce ss, a plate in the recess directly opposed.

to a cutterhead, and a plurality of spacediap art set screws for adjusting said plate,

substantially as set forth,

4:. In a machine for making battery separators, a pair of opposed rotary cutterheads arranged with one in advance of the 2 other and carrying grooving and planing means, a pair of feed rollers in front of each cutter-head, a guard for each cutterhead comprising parts resting against the wor; and transversely slotted e'nd exten- 30 sions, bearings for the feed rollers movably supported in the slots, springs acting on said bearings to force the feed rollers toward the Work, a saw in advance of the for ward pair of rollers located in a plane pass- 35 ing midway between them and extensions on said guard curved at their forward ends to lie closely adjacent toand concentric with the saw, substantially as set forth.

In witness whereof, I, have hereunto set 40 my hand and seal at Memphis, Tennessee, this 25th day of August, AVD, nineteen hundred and twenty-one. 1 a,
