WO OD WOBKENG-MACHINE Application filed August 30,

To all whom iv' may concern:

Be it known that I, n'rni J. Joncnnr', residing in Sheboygan Falls, in the county of Sheboygan and State of Visconsin, have invented new and useful Tmprovements in l'lfoodworking'-Machines, of which the following` is a description, reference being` had 'to the accompanying` drawings, which are a part of this specification.

This invention relates to improvements in woodworking` machines, and more particularly to that class known as planers.

One of the obj eots of said invention is to provide a woodworking` machine especially adapted for planing or dressing t-he surface of lumber such as boards and the like, said machine being` simple in construction, strong` and dni-able, and easily adjusted.

Another object is to provide means for planing lumher of varying thickness and widths simultaneously. i

Another object is to provide simple means for adjusting the machine to make cuts, in planing, of varying` thickness.

A further object is to provide means for alining' the cutter.

A still further object is to provide means whereby the cutter is made more easily accessible for sharpening` and repairs.

A still further object is to provide means for raising` and lowerin` the feed rolls without interfering with the power transmission to said rolls.

lVith the above, and other incidental objeots, in view the invention consists of the machine and parts or their equivalents, as hereinafter described.

in section; and, Fig. 10 is a detail in section of parts shown in Fig. 9.

Like numerals of reference refer to corresponding parts throughout the different. views of the drawings.

The reference numeral indicates the main supporting frame, which may be made of any uitable size or shape but is preferably cast in a single piece for strength and rigidity and is rectangular in horizontal plane.

The frame is provided with bearing brackets 16-16 integral therewith and extending forwardly and rearwardly of the front and rear portions respectively of the said frame, and these bearing brackets are adapted to support ournal boxes 17-17 disposed thereon. A shaft 18 is journaled in said bones and provided with. a number of longitudinally disposed knives 19-19 bolted thereto forming` the cutter of the machine. The Cutting edges of these knives are positioned equidistant from the center of the shaftso that when the cutter is revolved all of the knives will come into Cutting engagement with the surface being' planed.

A belt pulley 20 is fastened to one end of the cutter shaft 18 and is adapted tobe driven with a belt (not shown) in the usual manner. The lower surfaces of the ournal boxes are inclined and rest upon adjustable wedge blocks 21-21 the upper surfaces 22-22 of which are correspondingly inclined so that when the wedge blocks are moved in one direction the journal boxes and the cutter journaled therein will be raised, and when moved in the opposite direction, the journal boxes and the cutter journaled therein will be lowered, and by moving only one of the wedge blocks, the cutter may be properly alined with the surface upon which the material to be planed rests. The lower' portions of the wedge blocks are semi-circular in cross section and fit in correspondingly semi-circular depressions 23-23 in the brackets 16-16 so that the inclined surfaces of the wedge blocks will always coincide with the inclined lower surfaces of the journal hoxes in any position of adjustment. The semi-circular depressions 23-23 are longer than the wedge blocks 21-21 to allow an endwise movement of said blocks in adjusting` the height of the ournal blocks, and in order to move said wedge blocks, adjusting bolts 2-2-Lt threaded in the upwardly extending lugs 25-25 of the brackets 16-16 and bearing against the ends of said wedge blocks, are provided whereby a very fine adjustment of the cutter may be made' VVhen the cutter is properly alined the j ournal blocks are securely fastened to the brackets by means of bolts 26-26 which pass through openings in the brackets 16-16, through slots 27-27 in the wedge blocks 21-21 and are threaded into the lower portions of the journal blocks. The slots 27-27 in the wedge blocks permit of the said blocks being moved endwise by means of the bolts 24-24 when the bolts 26-26 are loosened.

A bed-plate 28 provided with elongated tongues resting on ways on the upper portion of the main frame is adjustably secured thereto by means of clamping bolts 29-29 passing through slots 30-30 in the bed-plate and threaded to the main frame. Other bolts 31-31 also pass through said slots and are threaded to the main frame and serve to more securely hold the bed plate in position on the main frame. A lever 32 pivotally connected at one end to the main frame and medially to one end of a connecting link 33 is disposed beneath the bed-plate near one end. The other end of the connecting link 33 is pivotally connected to the bed-plate by means of a pivot bolt 34 thereby providing convenient means for adjusting the position of the bed-plate on the main frame with relation to the cutter.

Two standards 35-35 bolted to the bed plate 28 and connected together at their upper ends by a cross piece 36 form a slideway for supporting a sectional feed roller frame 37 adjustably mounted thereon. This frame which consists of two side blocksV 38-38 dovetailed to the standards so as to be freely moved up and down by means of adjusting screws 39-39 threaded to said side blocks, are connected together rigidly by an angle iron 40. The forwardly projecting portion of the angle iron 40 serves as a guard to prevent the fingers accidentally coming in contact with the cutter or feed rollers while feeding material to the machine. The adjusting screws 39-39 pass through openings in the cross piece 36 and are supported and have their bearings therein. Miter gears 41-41 mounted on the upper ends of the adjusting screws 39-39 and in mesh with the miter gears 42-42 mounted on a horizontal shaft 43 extending across the machine above the standards and having bearings in lugs 44 extending up from the cross piece 36 are adapted to be revolved by means of the hand wheel 45 mounted on the forward end of the horizontal shaft, to adjust the height of the sectional feed roller frame above the bed plate, to accommodate lumber of different thicknesses.

A feed shaft 46 having bearings in both side blocks of the sectional feed roller frame is provided with a number of sprocket Wheels 47 rigidly connected thereto, and each sprocket wheel is provided with a sprocket chain 48 which passes around a section of a feed roller 49 having sprocket teeth 50 formed thereon. Each feed roller is loosely mounted on a short shaft 51 carried by a swinging pressure member 52 pivotally supported on the shaft 46. Each swinging pressure member consists of two side arms 53-53 joined together at their forward ends by a cross piece 54 integral therewith. The forward ends of the side members rest upon the angle iron 40 which serves as a stop to limit the downward movement of the pressure members. The rearward portions of the two side arms are inclined upwardly and are provided with elongated slots 55 to accommodate elongated nuts 56 loosely mounted on the feed shaft 46 on both sides of each V=,pro-cket wheel 47 and passing through said slots. The nuts fill the slot transversely but not longitudinally, thereby permitting the pressure frame to be moved forwardly with relation to the power shaft 46 to take up slack in the chains caused by wear. The pressure frames are moved by bolts 57-57 passing loosely through bolt holes in the rearward ends of said frames and threaded into the nuts 56. As the bolts are tightened the rear ends of the side arms will be advanced towards the power shaft 46, and the feed rolls connected to the forward portions of the side arms will be moved away from the power' shaft, thus tightening the Chains. The feed rollers are solid to provide sufficient weight to cause said rollers to positively feed the lumber to the cutter, and to prevent said rollers from slipping thereon, the peripheries thereof are serrated or toothed, the serrations also extcnding across the end of the sprocket chain teeth formed p 011 said rollers.

By forming the usual feed roll into a plurality of independently rotated and swinging rolls it is possible to feed lumber of different thicknesses and widths to the machine at the same time without any change of adjustment or any Variation of cut in planing.

A large sprocket wheel 58 connected to the rear end of the feed shaft 46 is provided with a sprocket chain 59 which depends therefrom and engages a small sprocket wheel 60 mounted in a rectangular swinging frame 61. The rectangular swing frame 61 is suspended by means of a link forined of two yokes 62 and 63 and an adjustable connecting rod 64 reversely threaded on its ends which engage threaded openings in both of the yokes. The connectiing rod is provided with a lock nut 65 to lock the said rod to the lower yoke and prevent its accidental rotation. The upper yoke 62 is pivotally connected to the feed shaft 46 on both sides of the sprocket wheel 58 and the lower yoke 63 is pivotally connected to lugs extending upwardly from the rectangular swinging frame G1.

The rear portion of the rectangular swinging frame G1 is pivotally mounted on a driving shaft G6 which has its bearings in the main frame. A small sprocket wheel 67 is mounted on the driving shaft 66 between the side members of the rectangnlar frame 61 and is provided with a sprocket chain 68 which surrounds a large sproeket wheel (39 connected to a short shaft 70 journaled in the forward portion of the rectangnlar f'ame 61. The sprocket wheel 60 is also connected to this shaft.

By means of the yokes and the connecting link, the swinging rectangular frame, and the sprocket Wheels and chains, it is possible to raise and lower the sectional feed roller frame, and to slide the bed plate and the sectional feed roller frame carried thereon rearwardly to adjust the cutter without stopping the rotation of the feed rolls as the construction permits the feed shaft being moved Vertically and horizontally without changing the distance apart of the chain connected shaft Centers.

1he driving shaft GG has loosely mounted thereon a drive pulley 71 located beneath the bed-plate which is driven in the usnal manner by a belt (not shown). The drive pulley is adapted to be connected to the driving shaft by means of a clutch member T2 'o Je'rated b i a oivoted foot lever T3 in the ordinary way.

An adjustable feed-plate 74: mounted on cranked rock shafts 75 and 76 which have their bearings 77-77 in the main frame is disposed above the main frame and in front of the rotatable cutter. The feed plate is provided with guide strips 78-78 to guide the lumber being planed in the proper direction.

The front ends of the cranked rock shafts have connected thereto disks 70 and 80 and to these disks are connected, pivotally` threaded blocks 81-8l. A connecting rod 82 reversely threaded at its ends is connected to said blocks. Another threaded block 83 is pivotally connected to the disk 80 and to this block is threaded a screw bolt 84 provided with a hand wheel 85 for rotating the same. The bolt 8% has its bearing` in a block 8G which is pivotally connected to a bracket 8? connected to the main frame. The feed plate is raised or lowered to increase or diminish the depth of the cut in planing by turning the hand wheel 85 which will revolve the disk 80 and by means of the connecting rod 82 will likewise revolve the disk 79, this will cause both cranked shafts to move and the cranked portions thereof upon which the feed plate is mounted will be either raised or lowered as the case may be,

depending upon the direction of rotation given to the hand wheel.

As the inner edge of the feed plate is beveled off and is positioned above a portion of the cutter and as close as possible thereto it is necessary, in lowering the plate, to also move it away from the cutter to prevent its being struck by said cutter. The construction as descri'bed accomplishes this result by means of the cranked shafts which in lowering the plate also move it away from the cutter, the arc of niovement of the cranked shafts being the same the radius of the cntter so that the inner edge of the feed plate will be substantially the same distance from the cutting edges of the knives in all ordinary positions of adjustment.

In order to level or align the feed plate with the bed plate the opening 88 of the bearing which surrounds the cranked portion of the crank shaft (5 is elong'ated so as to permit an independent movement of this shaft, which movement will tilt the feed plate to any angledesired. This independent movement of the crank shaft 7 5 is accomplished by turning` the connecting rod 82 which will revolve the disk 79 and the connected crank sha 't 7:3, the crank shaft 70 being held in adjusted position by means of the bolt 8a and the disk 80.

Tn operation, the different parts of the machine are adjusted and positioned as shown in the drawings .and boards being placed on the feed plate and pushed beneath the feed rolls will be drawn along over the cutter which will plane or dress the under surface of the boards to a depth corresponding to the distance the top of, said feed plate is positioned beneath the plane of the top of the radius of the cutter. n feeding lumber of different thickness to the machine, the different feed rolls will be raised different distances and will Continue to feed the boards in the same manner as before described. lVhen boards which are thicker than the distance between the feed plate and the angle iron are to be planed, the sectional feed roll frame is raised a proper distance by means of the hand wheel and the miter gears. Tf it is desired to replace a knife or examine the cutter, the hand bolts clamping the bed plate to the main frame are loosened and the bed plate with the feed roll frame carried thereon is moved rearwardly by means of the hand lever beneath said plate. The feed plate is also moved away from the cutter and lowered by means of the hand wheel and crank shafts which will allow clear access to the cutter. f it is desired to adjnst the heig'ht or angle of the cutter, this may be done by means of the adjustable wedge blocks and adjusting screws. The sprocket chains on the feed rolls may be adjusted Or tightened by means of the adJusting screws, and all of these adjnstments may be made While the machine is l adj ustable vertically With relation thereto, a

in operation.

From the foregoing description it Will be seen that the machine is simple in construction and operation and all necessary adjnstments are provided for.
