Application filed January 25, 1915. Serial No. 4,176.

To all whom it may concern:

Be it known that we, FRANKLIN L. LANE and FRANK R. WEAVER, citizens of the United States, residing at Beloit, in the county of Rock and State of lVisconsin, have invented certain new and useful Improve ments in Planers and Matchers, of which the following is a specification.

The invention relates to a planing, matching and finishing machine for acting upon lumber or other rough material to the end that in one passage through the machine the same shall be smooth finished on all its surfaces and also tongued, grooved, hollowbacked or otherwise prepared for use as ceiling, flooring and the like.

Among the featuresof construction characterizing the invention are improved means providing for the easy and accurate adjustment of the operating parts within a wide range to adapt the same to the requirements of the work in hand; also improvementsin the construction and mounting of the work ing parts whereby to effect compactness, elasticity in operation and capacity for per forming superior work; also other improvements in construction and operation which will hereinafter be made apparent.

In order that the invention may be readily understood by those skilled in the art, a preferred embodiment of the same in a wood working machine is set forth in the accompanying drawings and in the description based thereon. As, however, the invention is susceptible of embodiment in other and varied constructional forms dependent upon the material and the nature of the work to be performed, the drawing and description are to be taken in an illustrative and not in an unnecessarily limiting sense.

In the drawings Figure 1 is a top plan View of a wood working machine embody.- ing the invention; Fig. 2 is a side elevation of the same; Fig. 3 is a vertical longitudinal section on the line 33 of Fig. 1; Figs. 4, 5, 6 and 7 are vertical transverse sections taken on corresponding lines indicated in Figs. 1 and 2; Fig. 8 is a similar section taken on the line 8-8 of Fig. 2; Fig. 9 is a horizontal fragmentary section taken on the line 9 9 of Fig. 2; Fig. 10 is a vertical transverse section taken on the line 10-10 of Fig. 1; Fig. 11 is a front elevation of the main cutter head; Fig. 12 is an edge elevation of the 'is a detail-view in same; Fig. 13 is a section through the cutter head on the line 1313 of Fig. 11; Fig. 14 perspective of one of the knife adjusting blocks; and Fig. 15 is an edge elevation of a modified form of cutter head. I

Referring to the drawings more in detail, the machine is illustrated as comprising a frame 21 forming a support for the mounting of the various Working parts of the machine in operative relation to which the material isadapted to be passed lengthwise of the machine entering at the right hand endas illustrated in Figs. 1 and 2 and emerging in a finished condition from the left hand end as viewed in said figures. The material is fed into and through the machine by means of a series of adjustably fixed and yielding feed rollers arranged in pairs. Of

the first pair the fixed roller is indicated at 22 and the yielding roller at 23, theformer having a smooth surface and the latter a roughened or toothed surface, the succeeding pairs of rollers 24, 25, 26, 27, 28, and 29 have smooth surfaces on both the fixed and yielding members of each pair.

The feed rollers are driven in the following manner: Referring particularly to Figs. 1, to 4, the main shaft 32 driven by the pulley 33 has mounted thereon a drive pulley 34 from which the belt 35 passes around the driven pulley 36 upon the shaft 37. This shaft 37 has mounted thereon concentric of the pulley 36 a miter gear 38 which meshes with a larger miter gear 39 fixed upon the counter shaft 40 extending lengthwise of the machine frame and serving to transmit power to the several feed rolls. Upon the counter shaft 40 is mounted a bevel pinion 41 in mesh with the bevel pinion 42 fixed upon the vertical shaft 43 which carries pinions 44 and 45. Parallel to the vertical shaft 43 is another verticalshaft 46 carrying at its lower end a pinion 47 in mesh with the pinion 44 driven thereby. The upper end of the shaft 46 has mounted thereon the fixed feed roller 22. Likewise arranged parallel to the shaft 43 at an angle of 90 from the shaft 46 is a vertical shaft 48 carrying the pinion 49. in meshwith the pinion 45. The upper end of the shaft 48 serves as a pivot for the swinging bracket 50 upon shaft 70 of the fixed feed roll 2%.

46, and a8 and immediately behind the shaft e6, as seen in Fig. 3, and behind the shaft L8, as seen in Fig. -l, is another vertical shaft 51 carrying a pinion in mesh with and driven by the pinion l9, the shaft 31 carrying the ielding feed roll 23. By this means the feed rolls 22 and 23 are driven in opposite directions so as to feed the material therebetween and at the same time provision is made whereby the roll 23 may yield in an arcuate path about its pivot 48 without interfering in the driving thereof. At the opposite end of the counter shaft 40 is a bevel pinion 53 in mesh with a bevel pinion 5% carried by the vertical shaft 55 which has fixed thereon pinions 56 and 5'7, the former in mesh with the pinion 58 carried by the shaft 59 which has mounted thereon the fixed feed roll 28 at the exit end of the machine. The yielding feed roll of this pair is driven from the pinion 5'7 by means of other pinions and shafts arranged in substantially the same relation as that described for the driving of the yielding feed roll L63.

At an intermediate position the counter shaft l0 carries a bevel pinion 30 in mesh with a similar pinion 31 mounted upon the shaft 60 carrying pinions 61 and 62, the former in mesh with. the pinion 63 on the shaft (it of the fixed feed roll 26. The pinion 62 is in mesh with a pinion 65 by means of which its motion is transmitted to the pinion 66 on the shaft 67 which carries a pinion 68 in mesh with the pinion 69 on the The yielding feed rolls 25 and 27 are driven indirectly from the pinions 66 and 62 by means of interposed pinions and shafts arranged in the manner described with reference to the driving of the yielding feed roll 23. The shafts 46 and 70 of the fixed feed rolls and 24: are not journaled directly in the frame 21 but in a bracket 71 which is adjustable on said frame so as to provide for a slight adjustment of the feed rolls with reference to said frame, the adjust ment of the bracket 71 being permitted by the working of the bolts 72 in the slots 73 of a sliding plate 7+. and effected by the adjusting nuts 75 and set screws 76. The

sliding plate 7% is in turn adjustable on the frame 21 by means of links 77 having threaded engagement with the standards 78 and having at their opposite ends a connection by means of the eccentric straps '79 with the eccentrics 80 fixed on the shaft 81 which shaft is adapted to be rotated from its squared end 82 in any suitable manner as by a wrench or hand wheel and to be locked in adjusted posit-ion by means of the clamping nut 83, while additional provision is made by means of the lever nuts 84 for clamping the plate 7% in adjusted relation to the machine frame 21. This sliding plate 74 has along its extreme edge an upturned flanged a guide rail for the material entering the machine. Ordinarily the guiding surface or the rail 85 would be substantially flush with the adjustably fixed feed rolls and 21% although capable of slight adjustment relative to the feed rolls by means of the adjusting nuts 75 and set screws 7 6. When once brought into relative adjustment the guide rail and feed rolls are adjusted in unison by means of the shaft 81 and the links 77.

The following provision is made for the automatic yielding and the manual quick release of the yielding member of each pair of feed rolls, the description as applied to the first pair being also applicable to each of the other pairs: Having particular reference to Fig. 9 it will be observed that the feed roll shaft 51 andits gears =l9 and 52 are inclosed within a housing 86 adapted to swing about the shaft 48 as a pivot. The housing 86 is provided with a boss 87 serving as a bearing for a pivot 88 by means of which a lever 89 is fulcrumed to the housing. This lever 89 is also fulcrumed at 90 in a bearing block 91 threaded upon the spindle 92 having a squared outer end 93 and guided within an arm 9i carried by the boxing of the shaft 46 of the fixed feed roll. The spindle 92 extends beyond this guiding bearing and has enveloping the same a spring 95 bearing at one end against the arm 9t and at the opposite end against the washer 96 positioned upon the end of the spindle by means of the nuts 97. It will be observed, that, having reference to Fig. 9, the spindle 92 serves as a link connecting the lever 89 with the arm 9 and that in the normal position of the lever 89, here represented, this link lies slightly to the right of the fulcrum 88, the effect being to hold the lever in its normal closed position. If the lever 89 be drawn outwardly toward the observer the first result is to swing the outer end of the link spindle to the left and to the other side of the fulcrum 88 and thereafter the ivot 88 and with it the free end of the housing and also the shaft 51 with the yielding feed roll are swung outwardly about the pivot 90 whereby the space between the feed rolls 22 and 23 is increased and the engagement of the rolls upon a piece of material therebetween is released. By means of the levers 89 it will thus be seen that the material in the machine may be quickly released from engagement between any pair of feed rolls for withdrawal or adjustment.

Next to the first st of feed rolls 22 and 23 is suitably mounted a vertical shaft 98 carrying a drive pulley 99 and having fixed upon its upper end a hollow backed cutter head 100, fitted with knives 101 adapted to finish one side of the material and to hollowback the same by means of the cutter part clamping blocks 111 have a portion hol- 102. The shape ofthese knives and the nato accord with the finish desired to be given to that face of the material indicated at 103, in Fig. 5, in the position to be operated upon. The cutter shaft 98 has its bearing within a boxing 104 provided with a lateral extension 105 which is transversely apertured for the reception of a fixed shaft 106 extending transversely of the machine frame through guiding brackets 107 within which it is slidable. Also rotatably mounted but 'without longitudinal movement, in the box ing 104 is an adjusting spindle 108 threaded within a boss 109 of the machine frame and having a squared end 108 by means of which spindle the boxing 104 and with it the cutter head and shaft are adjusted toward and from the machine frame causing the 'fixed shaft 106 to slide within its guiding brackets 107. A set screw 110 is provided for gaging the adjustment of the cutter head and the parts are firmly clamped in adjusted position by means of blocks 111 guided for vertical movement within the bosses 112 of the brackets 107 upon screw spindles 113 threaded in the machine frame at 114 and provided with operating handles 115. The

lowed out, as indicated at 116 to fit the surface of the shaft 106 so that when the spindles 113 are rotated the blocks 111 are caused? 1 to engage and firmly: clamp the shaft 116 'so as to maintain the shaft 98 and the cutter head 100 in adjusted position.

The cutter head 100 is inclosed within a housing 117 having an open side 118 for the attachment of an exhaust device to carry off shavings and the like, the housing being pivoted eccentric to the shaft 98 for swinging movement in order to give access to the cutter head. The swinging housing is latched and released in the manner follow ing: A spring pressed bolt 119 is vertically mounted within the housing, the lower end projecting at 120 and the upper end provided with a handle 121 by means of which it may be lifted in opposition to its spring 122. A keeper rod 123 is horizontally mounted within a bracket 124 carried by the non-rotatable shaft 106 and equipped with a spring 125 bearing at one end against said bracket and at the other end against the washer 126 and the nut 127. The outer end of the keeper rod is provided with an aperture for the reception of the lower end 120 of the bolt and has a downturned terminal portion 128 up which the end of the bolt is adapted to ride before reaching the recess. The keeper rod also has a rearwardly facing shoulder portion 129 adapted to be engaged by the nose 130 of the latch lever 131. The housing 117 has a lip portion 117 which acts as a chip breaker and is held yieldingly in contact with the stock passing throughthe machine by means of the spring 125. it will be observed that as the cutter and'housing are adjusted toward and from the stock by the sliding of the shaft 106 the action of the spring 125 on the chip breaker would vary were it not that the bracket carrying the rod 123 and spring 125 is in turn carried by the shaft 106, whereby the tension of the spring remains unchanged under various adjustments of the cutter head. To release the housing 117 the bolt 119 is retracted out of engagement with the keeper by means of its handle 121 and may then be swung to the open position. In closing, the lower end of the bolt rides up the inclined end of the keeper rod and snaps into the recess. This operation would ensue without difliculty were it not that the spring 125 acts through the keeper upon the bolt to pull the housing strongly to the right as viewed in Fig. 10. In order to hold the keeper in its extended position against the spring 125 until engaged by the bolt 119 the lever 131 is provided by means of which the operator pushing downward upon the end of the lever bears outwardly against the shoulder 129 of the keeper rod holding the latter in extended position for easy engagement with the bolt until the latter has engaged within the recess. The lever 131 may also be utilized to relieve the tension upon the keeper rod while the bolt is being with drawn in the opening movement. The upward movement of the lever 131 is limited by means of the step 132 in order that the spring 125 may not be allowed to draw the keeper rod 123 inwardly too far to be engaged by the bolt or to destroy the engagement between the shoulder 129 and the nose 130 of'the level. 1

Beyond the hollow back cutter head is mounted a pair of feed rolls 24 and 25, the yielding member 25 of which is mounted for swinging movement and provided with a quick release lever connection in the same manner as the yielding feed roll 23, previously described. Between the pair of feed rolls 24 and 25 and theinext pair of feed rolls 26, 27, which are similarly mounted, is arranged a main finishing cutter head 133 upon the shaft 134 j ournaled inthe bearings 135, 136 at a slight inclination to the horizontal, as most clearly shown in Fig. 6. The cutter head 133 has a convex or beveled front face, the inclination to each other of those portions of the face on opposite sides of the center being slight and of such extent that when mounted with the shaft 134 at a slight inclination to the horizontal the lower portion of the face of the cutter head will occupy a vertical position, or in aplane par allel to the plane of travel of the stock through the machine while the upper portion of the face will lie in a plane at an angle to the vertical and at an angle to the plane of the travel of the stock.

\Vithin the cutter head are mounted a plurality of knives 137 with their cutting edges conforming to the bevel face of the head and substantially flush with the said front face. These knives are mounted within slots of the cutter head in conjunction with gibs 138 having offset heads 139 by means of which their position within the slots is fixed with their outer ends adjacent the cutting edges of the knives where they act as chip-breakers. The knives 137 are positioned and firmly held within the slots by means of blocks 110 of a general cylindrical shape but having a bevel face 141. The blocks are slidably mounted within cylindrical recesses 112 the axes of which are substantially parallel to the axis of the cutter head and therefore at aninclination to the knife slots which are at an angle to the axis of the cutter head the inclined face 141 of the block being substantially parallel to the slot and consequently adapted to bear against the flat face of the gib. The rear end of each block 140 is borne upon by a set screw 1 13 threaded in the cutter head and squared at 1461 for engagement by a suitable tool. For convenience in manufacture the knife slots are milled and extend outwardly to a periphery of the cutter head and a rim 145 is thereafter placed about the cutter head inclosing the ends of the slot, being held in place by means of the screws 1 16.

The front face of the cutter head where the knives project is provided with grooves 147, that portion of the groove in front of the knife edge having a greater capacity at its outer end, such increase of capacity being attained, as illustrated, by forming said groove of increasing width toward its outer end although the same result may be attained by increasing the depth of the groove toward the outer end, the object being in both cases to provide a clearance channel for the chips by which they are discharged radially.

The object in beveling the operative face of the cutter and mounting its shaft at such an inclination that those knives which are operating upon the stock shall have their cutting edges substantially parallel to the plane of travel of the stock while the opposite knives shall be inclined to such plane, is that the knives shall gradually enter the material and gradually leave the same with the grain of the wool and effect a drawing out throughout whereby knife marks are entirely avoided and an absolutely smooth finish imparted to the work.

It will be noted that the front face of the cutter head between the knives is substantially flush with the cutting edges of the knives themselves, providing for a projection of the knives merely sufficient to make a thin out. The object of this provision is that the material in its passage through the machine shall be supported by the face of the cutter head. This is of great importance particularly where a large cutter head is employed and where warped stock is being treated. Otherwise the material, being unsupported, could spring toward the cutter head and the depth of the cut would be non-uniform.

The cutter head shaft 134 is provided at its rear end with an end thrust bearing 148 adjustable by means of a hand wheel 149 while the forward end of said shaft is provided with an end thrust bearing 150 which is yielding and under control of a compression spring 151, the tension of which spring is adjustable to provide for greater or less resistance. The cutter head 133 is inclosed within a housing 152 open at its upper side at 153 for communication with an exhaust device and hinged at 15 1 so as to swing in a vertical plane. To the free edge of the housing on that side opposite its pivot 154 is attached a shoe 155 vertically adjustable with reference to the housing by means of bolts 156 engaging within slots 157. The shoe 155 rests upon the upper edge of the stock and under the weight of the housing holds the stock firmly down upon the bed while being operated upon by knives of the cutter head. In order that the lower face of the shoe shall at all times be parallel to and rest throughout its length upon the upper edge of the stock this vertical adjustment is provided. If the shoe were fixed in its relation to the housing the parallel relation of its lower edge to the horizontal would be disturbed when stock of different widths were inserted and the housing thereby lifted or lowered about its pivot. As here arranged the position of the housing is always the same and the shoe is raised or lowered vertically and the horizontal relation of its lower edge maintained. Farther along and between the pairs of feed rolls 26, 27, and 28, 29 is arranged a pair of cooperating cutter heads one above the other and adapted to act upon the upper and lower edges respectively of the stock to finish the same or provide a tongue and groove where flooring is being made. These cutter heads and their housing are substantially the same, difiering only in the knives with which they are provided.

The tongue cutter head 158 is fixed upon a shaft 159 carrying a pulley 160 and provided at its forward end with an adjustable end thrust bearing 161 and at its rear end with a yielding spring pressed end thrust bearing 162. The groove cutter head 163 is likewise fixed upon a shaft 164 carrying a pulley 165 and provided at its front end with an adjustable end thrust bearing 166 ener pulley and at its rear end with a yielding end thrust bearing contained within a housing 167. The stock in its passage between the tongue and groove cutter heads is held firmly against the gage guides 168 and 169 by means of a pressure roll 170 which is mounted in a bearing bracket 171 forming a housing and hinged at 172, the bracket and with it the roll being pressed inwardly by means of the spring 173 mounted upon the rod 174 and engaging the arm 175 of said bracket.

Provision is made for the adjustment of the tongue and groove cutter heads toward and from each other to accommodate stock of different widths in the manner following: The cutter head shafts 159 and 16 1 are journaled within bearing boxes 176 and 177 respectively, mounted for vertical adjustment 1 within guides 178 and 17 9 ofthe machine frame as is most clearly shown in Figs. 7 and 8. The bearing boxes 176 are engaged by a pair of screw spindles 180 connected at their upper end by means of a cross shaft 181 and the bevel gears 182 and 183. One of the bevel. gears 182 being in turn in mesh with a bevel gear 184 carried by a shaft 185 and provided with a handwheel 186. The bearing boxes 177 are engaged by a pair of screw spindles 187 each provided with a worm wheel 188, each of which is in mesh with a worm 189 on the shaft 190 provided at its front end with a squared portion 191; By turning the hand wheel 186 and the worm shaft 190 the respective bearing boxes 176 and 177 will be moved upwardly or downwardly so as to bring the knives of the tongueand groove cutters closer together or farther apart. In order to provide for the clamping of the beaing boxes in adjusted position and to release the same for adjustment when desired a cam rod 192 is provided, equipped with an operating handle 193, said cam rod bearing against a wear plate on one of the guides'178 and encircled by hearing knuckles of strut rods 194 extending across the intervening space and having an adjustable bearing by means of the nuts 195 upon the opposite guide 179. The guide 179 is split at 196 (Fig. 8) so as to permit the same toyield slightly and thus providing for the clamping and releasing of the cooperating portions of the bearing boxes 176.

The several cutter heads are driven from the one shaft 32 in the manner following: The pulley 99 of the hollow back cutter head is driven by means of the belt 197 from the pulley 198, the belt traversing the belt tight- 199 which is acted upon by the weight 200'. The main surfacing cutter head 133 and the'tongue and groove cutter heads 158 and 163 are driven from the pulley 201 by means of the belt 202 which passes from the upper side of said pulley over' the pulley 160, under the pulley 165, around the pulley 203 of the shaft 134 and back to i the said drive pulley 201. The driving of the feed rolls and consequentlythe passage of-the material through the machine is controlled by a hand lever 204;, fulcrumed at 205 and connected by means of the arm 206 with a link 207 which in turn is pivoted to an arm 208 fixed upon the rock shaft 209, which shaft carries oppositely arranged belt tensioning pulleys 210 and 211 by means of which under the control of the lever 204 the belt 35 is loosened or tightened so as to start and stop the driving of the countershaft 40 and the rotation of the feed rolls. The stock leaving the tongue and groove cutters passesbetween the feed rolls 28 and 29 and is by them fed from the machine in a finished condition requiring no further treatment .to fit the same for the reception of a high polish or for'use underthe most exacting conditions.

In Fig. 15 is shown in edge elevation a slightly modified form of cutter head, the features of difference being that the front face of the head, instead of lying throughout in approximately the rotational plane of the cutting edges of the tools and being provided with special chip-clearance grooves,

has at certain points intermediate the knives 9 projecting bosses 212 the front slightly beveled faces of which extend to a plane sub stantially flush with the knife edges and form a side support for the stock, the depressed face of the head between the bosses and knives serving the same chip clearance function as the grooves 117 in the former case.
