v VENEER-CORE MACHINE.

Application led. September rlhe purpose of 'my present invention is to provide a machine for facilitating the economical shaping, gluing' and assembling of thev various members entering into the construction of a built-up core, which is later covered with face veneei. I

rlliis machine is useful in any of the woodworking industries using veneer construction but is more particularly adapted for work on parts entering into doors. i

More particularly, it is my object to provide a machine whereby the members of a builtsup Core are cut to shape during the passage through vthe machine, and whereby each of the core membersfis glued on one side and one of the edge strips is glued.

It is desirable to make various products of wood, for, example. door stiles, of a built-y up veneered core. This is true because of the desirability for economy in the use of smaller material and of cheaper material for the cores than lfor the veneer strips.

rlhe assembling of a veneered core door stile for example is an operation requiring considerable labor andit is necessary that ythe work be facilitated in every possible way, in order to keep t-he labor cost downto a minimum, in order that the increased labor cost may not offset the saving on material.

I have therefore provided a machine for facilitating the assembling of veneered cores for door Stiles and other products of similar nature. This machine facilitates the ripping and dressing of the lcore stock, the automatic movement of the core stock from the ripping to the dressing mechanism, either with linear movement or with a linear movement and axial rotation,v the gluing of one surface of each piece of core stock, theV delivery of tliedressed and glued core stock io an assembling table, the'furnishing of glued and of unglued edge strips to the assembling` table, and the so mounting of the means for operatingon the core stock and the means for operating on the edge strips, that the stock may 4be simultaneously moved to proper positions with relation to the asseuil-iling table.

Likewise, the whole machine may be con* veniently moved to proper positions for re-V ceiving stocl'from different bins.

Core stock is fed to the mechanism which rips the core stock to its desired width and then delivers the ripped blocks from the ripping mechanism to a dressing mechanism by direct linear movement or by linear movement and axial rotation. The core blocks are then dressed on one or two sides, either straight-faced or tongued and grooved, as may be desired, and are then automatically moved past a gluing mechanism, by which one side is glued. They are then delivered to the assembling table. L Provision is made for supplying part of the edge strips automatically from a hopper, supplying glue to them, and delivering them to the assembling table adjacent to the point of delivery of the core stock. The rest of the edge strips are carried on a rack on the machine.

Controlling means are provided for the edge strip handling mechanism adjacent to the delivery end of the strip handling mechanism and the core stock handling mechanism and consequently adjacent to the assembling table.

The core stock handling mechanism and the edge strip' handling mechanism are so mounted as to be simultaneously adjustable along a track, so that core stock or edge strips may be taken from different supply bins.

I shall now proceed to describe first the mechanism for acting on the core stock and then the mechanism for gluing, the edge strips and delivering them to the assembling table.

@are Stock rz'ppz'ag, dressing, glu/ag and cle- Zwermg mecwmcsm The main frame of the machine is indicated at 10 in Figures 1, 2, 7 and so forth, and is preferably made of two parts, having their flanges 11 and 12, (Figure 2), bolted together as shown.

The frame 10 is supported on two spaced wheel beams 13, as shown in Figures 1, 2 and 8, each of which has two flanged wheels 14 traveling on tracks 15, so that the whole machine may be readily moved sidewise on the tracks.

It will, of course, be understoodV that the frame 10 has suitable flanges and bosses for supporting' and being connected with various other parts, which will be described.

At the front or feeding end of the machine on the left-hand side, there is supported a table 16 for core stock. (Figures 1 and 3). Core stock may be supplied te the table 16 in any suitable way.

Adjacent to the table 16 is what may be called the bed 17, supported on the main Vframe or made integral therewith, as may be desired. Stock is fed by hand from the table 16 to the ripping mechanism.

On the bed 17 is mounted a guide 18.

Any means may be employed suitable for the purpose of supporting the guide 18 for Y lateral adjustment.

In the bed 17 is a slot 19 for the saw 20. A. suitable bracket 2 1 supports a motor 22 having the .saw 2O mounted on its shaft.

The motor 22 and other motors hereinafter referred to are mounted on the frame 10 for vertical adjustment as illustrated for instance in Figures 7 and 15.

The bracket" 21 Vand the brackets for the other motors have uprights, that for the bracket 21 being indicated at 24 in Figure 7, mounted for vertical adjustment in the gibbed ways 23 in the frame 10.

The upright 24 has a lug 25 (see Figure 7) to receive a screw bolt 26, the head of which rests on the frame 10 for limiting the downward movement of the bracket 21 in the gibbed ways of the frame 10.

By rotating the screw bolt 26, it may be raised or lowered for regulating the height of the motor 22 and consequently the height of the saw 2O for cutting core stock of different sizes.

For holding the core stock and feeding it past the saw, there are provided spur wheels and a roller as follows: Y

Supported on the bed 17', as illustrated for instance in Figure 7, is a b 'acket 27, in which is mounted a transverse shaft 28, (Figure There is provided aframe, consisting of the side members 29, each having` one end pivot-ally mounted on the shaft 28, which side members are connected by a cross plate 30, as shown in Figure rlhe side members 29 at their ends opposite the pivotal connection with the shaft 28 carry a rotatably mounted transverse shaft 31, (Figure On one end of the shaft 31 just forwardly with relation to the saw 26 is a spur wheel 32. (Figures 1, 3 and 7).

Pivoted on the shaft 28 between and under the side members 29 are the side members 33 of a second frame, which areconnected by a cross bar 34. (Figure 5). The side members 33 carry a shaft 35, as shown in Figures 1, 3 and 5, on one end of which Vabove and spaced laterally from the saw 2O is a spur feed wheel 36.'

In order to properly adjust the downward tension on the spur wheels 32 and 36 and on the stock being fed to the saw 20, I provide'the bracket 27 rwith a portion 43 eX- tending above the shaft 28 between the side members 33. On the portion 43 of the bracket 27 is a spring 44 of the .so-called flat type, which is extended over-"the cross bar 34, as indicated` at 45 in Figure 5.

On the spring 44 is a spacer Vblock 43*L on which is al spring 47 similar Vto the spring 44. The spring 47 extends over the cross plate 30, between the side members 29, which support the spur wheel 32, as shown at 46, 1n Figure 5.

vThe springs 44V and 47 and the spacer block 43a are secured to the portion 43 by cap screws or the like 43h.

To limit the downward movement of the spur wheel 32, I provide al screw-threaded.

i upwardly through an enlarged hole 30a (Figure'3) in the plate 3() and terminates in a squared portion 49. The lower end of the rod 47a rests against the bed 17.

Thus it will be seen that I have a spring pressure for causing the spur wheels 32 and 36 to bear down against the core stock passing through the ripping mechanism and that by turning the rods 4() and 47", the spur wheels 32 and 36 may be adjusted to a position slightly below the level of the Vtop of the core stock and thereby allow the stock to be forced under them and still derive the full benefit of the pressure yof lthe springs 44 and 47. For turning the rods 40 and 47u, I provide a wrench 50, having` a squared socket in one end to lit the squared portions 41 and 49 of the rods 40 and 47.

Beneath the bed 17 is another spur wheel 206 on a shaft 205, which extends through an opening 207 in the bedy 17.

Pivotally supported on the shaft 28 is a rearwardly extending arm 51, which supports a roller 52 adapted to rest by gravity on the core stock, after the core stock has passed the saw 20 for holding such stock Y down on the bed 17 and the spur wheel 'Ihe stock is taken from the table 16, placed against the Vguide 18, after the guide has been properly adjusted and pushed under the spurwheel 32. The spur wheel 32 then advances the stock toward the 'saw'20' (see Figure 3), and as the stockv advances it is also acted upon by the spur wheel 36. Just rearwardly from the saw, there is mounted a spring of the flat type, as indicated at 53, which extends from its forward end rearwardly in line with the saw 20. and at its rearward end is curved to the machine as at 54.

The purpose of the springguide device 53 is to move the stock sawed from the piece which has been cut to size to the left. If the piece thus cut oil is large enough for further use, the operator again passes it. through the ripping mechanism. If not, it is allowed vto drop oil' the table.

The means for operating the spur wheels 32 and 36 and thev roller 52 will be hereinafter described. The spring 53 is called a splitter.

001'@ stock guides.

The sawed core stock membersv are fed from the bed 17 to a turret, guide. This turret guide, shown in Figures 1, 3, 4, 5, 8, 9 and 10, comprises a plate, which may be in the form ofa cast-ing 55, illustrated in Figures 5, 9.and 10. The plate 55 vhas at its ends the ears 56 and 57 mounted on trunnions 58 rotatably supported on the main frame 10. (See Figures 9 and 10.)v

On opposite sides ofthe plate l55 are mountedguides, one of'which is for ythe purpose of guiding the core stock in a direct line, and the other ofwhich is for guiding the core-stock and turning it a quarter turn during its movement through the guide.

The first, which I shall Vfor convenience call the straight guide, is illustrated in section in Figure 9, and comprises an angle bar 59 secured to the plate 50 and a Z bar 60 secured in spaced position. The bars 59 and 60 form a guide passage 61 substantially rectangular in cross section and large enough to receive any stock, which the machine is designed to handle. I

`When the turret member is moved with the straight guide up, the core stock moves in` a direct line, and without rotation through the guide, each piece being pushed along by the succeeding piece.. The turret` device can be rotated on the trunnions 58. To hold either guide, the ear 57 is provided above and below the trunnions 58 with screw-threaded openings 62. A screw .bolt 63 is extended through a portion of the frame 1() and may be screwed into either of the openingsr62 for locking the turret with either guide up.

What I shall call the spiral guide is illust-rated in Figures 5, 9 and 10 for example and is intended to guide the stock as it is advanced and to give it a quarter turn. Mounted on the plate 55 on the side opposite the straight guide is a series of spaced yokes 64. The yokes64 each have a rectangular opening 65 having its center substantially on the central line of travel of the core stock. p

These openings 65 are somewhat greater in cross section than the cross section of any core stock fed therethrough. Y

The first yoke at the lfront end of the series has the sides of the rectangular open ing 65 arranged in Vertical and horizontal ltr planes orl nearly so., In each succeeding n yoke, the openings are so arranged that theirA sides incline atv regularlypronounced angles. Frompthe sides vot the opening inthe first yoke, the' inclination of the angles is such that in the last yoke of the series the sides of the rectangular opening are Yagain in substantially vertical and horizontal planes. A

They whole efect,vhowever, in `the varia# tion ofthe arrangement of the openings, is that in passing from the first yoke tothe last, the rectangular outline of the opening has rotated on an axis parallel to the path of advance through an angle of ninety degrees. Thus, we have what might .be called a series of spirally arranged rectangular openings.

Secured to the first yoke 64 are four long strip steel springs 66. These springs 66 are each provided with a twist along a lengthwise axis to lie flat against the respective sides of the series of rectangular openings in the series of yokes Gs.

Thus the strips lyingin horizontal plane at the front of the guide will lie in vertical planes at the rear end, and those which lie in vertical planes at the front of the guide will lie in horizontal planes at the rear.

The front ends of the strips are bent at right angles as at 67 and secured to the front yoke 64 by means of bolts 68.

`At intervals along the length of these strip springs G6 are short springs v69 secured to the yokes, intending to press the long spiral springs 6G inwardly.

The object of the entire arrangement of yokes, springs and springs G9 is to provide a yielding tubeshaped spiral guide with an opening rectangular in cross section at any point in its length, and which in its entire length makes an axial twist of one-quarter of a turn. A 1t will be seen that a piece of core stock forced through this guide will have a constant tendency to twist and in passing through the guide will have been given a quarter turn.

The cor'e stock is discharged from either of the guides above described upon the bed 70 for the core stock dressing mechanism.

@are s250071; dressing mechanism.

Upon the bed 7() are mounted in succession, feed rolls, a chip breaker, a top dresser head, a top pressure shoe, a lower dresser head, an adjustable-rear table, a glue pot and a glue roller, which will now be described. BecauseI the feed rollers are mounted partially on the motor for the top dresser' head, I will first describe the mounting of that motor. The top dresser head motor .71 (see Figure l) is supported on a bracket 72 having an upright member 7? similar to the upright member 2l of the bracket 2l and mounted in gibbed ways 23, such as have been described.

Supported on the bed 70 is a bracket 74 (see vFigures 1,2, 4 and 6), which has an extension 7 5. Rotatably mounted in the extension 75 is a rod 76 having a shoulder above the extension 75 and a screw-threaded portion 77 below it. A collar 78 is fixed in the rod 7 6 below the extension 75. The

screw-threaded portion 77 is extended through a screw-threaded hole in the bracket 72 and the boss 79 formed thereon.

The upper end of the rod 76 is squared to receive a removable wrench or crank handle 80 similar to the wrench 50.

By rotating the rod 76 in the extension 7 5, the screw-threaded connection between the rod and the bracket 72 willv impart vertical raising or lowering movement to the bracket 72 and the motor 7l mounted thereon. Y

Fixed on the motor 7l is a bracket 81, shown in Figures l and 4, which projects laterally over the bed 70.

Mounted in the bracket 8l above the bed 70 and above the path of travel of the stock passing along the bed are longitudinally spaced screw-threaded rods 82 having nuts 8? thereon above the bracket 81.

The rods 82 slide freely .in longitudinally slotted holes 8la in the bracket 8l.

@n each rod v82 below the bracket 8l are nutsY Sil and between the nuts 8,4 and the bracket 81 are springs 85.

0n the lower ends of the rods 82 are yokes 86 in which are mounted shafts 87 and 88 respectively carrying the spur feed wheels 89 and' 90. Y

Pivotally supported on theouter ends of the shaft 88 (Figure 4l) are links 91 extending rearwardly and forwardly' and pivoted at their forward ends on a transverse shaft 92 mounted'on brackets 93 on the frame l0, as shown in Figure 6.

Similarly pivotally mounted onthe ends of the shaft 88 are linksl 94 extending forwardly and downwardly and pivoted i at their lower ends on a shaft 95 supported by the bracket 93. 'Y Y y The hubs 86EL of the yokes S6 are large enough to receive the hubs 86h of vthe links 91 and 94. The hubs 86 have split ears Sti and clamping bolts 86 (Figures'a and 8). The bolts 861 are loosened during vertical adjustment of the feed rollers S9 andr90 and tightened after this adjustment isV made.

A curved pressure spring 9G isV supported on the bracket Sl and is arranged to yieldinglyV press theV moving stock against the bed 70. (See Figure 6.)

Referring to the feed rollers 89 and 90, it will be seen that they have a positive vertical adjustment by means of the nuts and also that they have a certain degree of yielding, vertical adjustment against theY tension of the springs 85 for accon'nnodat ing said rollers to the thickness of the stock being operated en rlthey also have appositive vertical adjustment due to the fact that they are raised and lowered with the motor 7l when the motor is adjusted for operating on different thicknesses of stock.

Core stock passing beneath the rollers 89 and 90 will cause a slightv swinging movement of the links 91 and-94 and a corresponding movement of the rods 32, the

yokes 86 ot which are clamped to the links by t-he bolts 86d. The elongateclholes 81a in the bracket 31 permit 'this movement.

On the shaft 97 of the motor 71 is the 'top dresser head 98 for dressing the top surface of the stock passing through the machine.

On the bed rests the guides 99 having the elongated slots 100 through which are extended the lock bolts 101 mounted in the bed 70. i

The chip breaker 102 (Figure 6) has a yoke 103, (see Figures 4 and 6), the arms otl which are mounted on a transverse shaft 104 mounted in bearings 105 on the bracket 74. The yoke-103 lhas a forwardly projecting arm 106 in which is adjustably mounted a set screw 107, the lower end of which adjustably rests on the bracket 31, as shown in Figures 4 and 6.

It will thus be' seen that the chip breaker `will maintain its operating position in any vertical adjustment oit-thc top dresser head 98. I

J ust rearwardly `of the ytop dresser head is mounted the top pressure shoe 108. (See Figures 4 and 6).`

The bracket 74 has a connecting member 109 and an horizontal extension 110. Rotatably but non-slidably mounted in the extension 110 (Figure 6) is an upright'rod or the like 111 having on its upper end, th-e hand wheel 112 and having its lower end screw-threaded as at 113, and screwedinto a screw-threaded opening 114 in a bracket 115, which supports the shoe 108.

The bracket 115 has a vertically elongated slot 116.` A headed screw-threaded bolt 117 is extended through the hole116 and is'screwcd into the connecting member 109 or the bracket 74 as shown in Figure 6.

1t will thus be seen that ythe pressure shoe 10S may be'raised or low-ered by, loosening the screw bolt'117 and rotating theV screwthreaded rod 111, and may thenbe held rigidly in position by tightening the screw bolt 117. The 'forward end oit the shoe 10S is preferably slightly rip-curved as'at 118.

Referring now to the lower dresser head, it will be noted that there is provided a bracket 119 similar to the bracket 72 having an upright member 120 mounted in gibbed ways similar to those already described. formed in a portion ofthe 'frame 10. The bracket 119 is raised and lowered by means ot a rod 121 (see Figure 1) rotatably but non-slidably mounted in the extension in the same manner as the rod 76 already described. v

The lower end of the rod `121 is screwthreaded as at 122 and has a screw-threaded connection with thel bracket 119 and the boss 123 thereon.

On thg bracketv 119 is a' motorV 124 (Figures 4 and 8) on the shaft 125 of which is the lower dresser head 126 shown in Figure 6, which operatesthrough a hole 127 in the bed 70.

The rear portion 70 of the b-ed 70 is detachable and is adjustable vertically.

"lhe bed portion 705L is substantially triangular in vertical, longitudinal, crosssection, as shown in Figure 6.

Below it, a bracket 128 is supported on the frame 10. Rotatably mounted in the bracket 12S is the screw-threaded rod 129, which is held against sliding movement by a shoulder and by the collar 130, andhas a screw-threaded end 131 screwed into a suitable threaded socket in the b-ed portion 7 0n.'

On the screw rod 129 is a hand wheel 132 for adjusting the bed 7 0d.

Mounted on the adjustable bed section 70n is a glue pot 133. 'The glue pot is covered by a top member 134, which forms an eXtension 01' the bed portion 70fL and is provided with a suitable opening 135 through which projects the upper portion of the corrugatedfaced glue roller 136. y Y Y i On the interior of the glue pot-133, upwardly opening` U-shapedyokes 137 are supported on the side walls ot the glue pot. (See Figures 4 and 13).

Figure 13 shows a portion ofthe gluing mechanism for the edge strips,'but the yokes 137 for both gluing mechanisms are .the

same. l f

rlthe yokes 137 receive the ends of the shaft 138 of the roller 136. From the bed members 70, 70 and 134, the 'stock is delivered to the assembling table 139..

Supported above the bed 141 rearwardly of the hopper member 148 is a hold-down strip 150, shown in Figures 2 and 4, supported by the brackets 151.

At the rear end of the portion of the machine now being described is a glue pot 1.52 similar in structure to the glue pct 133, al-

i ready described, and having a similar top or cover member 153 with an opening 154 therein. The top member 153 forms an extension of the bed 141.

The glue pot 152 has secured to its side walls, the U-shaped members 155, similar to the U-shaped members 137, which suppcrt the shaft- 156 of a glue roller 136, similar to that already described. One end of the shaft 156 has formed therein a slot 158. which receives a flat extension 159 of the shaft 160.

rlhe shaft 160 is extended through one of the walls of the glue pot 152, as shown in Figure 4, through a packing gland 161, whereby a tight joint is provided..

Above the glue rollers mentioned are holddown rollers.

A bracket 162 is supported on the gluepot 133. To the bracket 162 is pivoted an arm 163, shown in Figures 1 and 4, from which is rotatably mounted a hold-down roller 164, which rests by gravity on the core stock passing' through the first above-described mechanism and over the glue roller in the pot 133.

Supported on the glue pot 152 is a bracket 165 to which is pivoted an arm 166. A.A roller 167 is rotatably supported on the arm 166 above the glue roller 136 in the glue pot 152. The arm 166 has an extension 168 on which a weight 169 is adjustably mounted and fixed by means of a set screw 170, so` that the weight may assist in holding the roller 167 against the edge strip stock.

I will now describe the mechanism for actuating the various operative mechanisms of the machine. j

It will be understood that the motors 22. 71 and 124 are operated from an electrical power line.

The outer end of the shaft of the motor 124 as shown in Figure 1 has thereon a pulley 171. Supported on the wheel beams 13 is a longitudinally arranged channel bar frame member 172. A transverse operating shaft 173 is mounted in bearings 174 on the frame 10 and in a bearing 175 on the channel bar 172 and in a bearing 176 carried by the bracket 177, which is in turn supported onthe bed 141. y(See Figures 2. and 8)'.

On the shaft 173 is a large pulley 178 in line with the pulley 171. A belt 179 travels on the pulleys 171 and 178 for transmitting rotation from the shaft of the motor 124 to the operating shaft 173.

A shaft 180 is mounted in suitable bearings 181 on the main frame 10 and in the bearing 182 carried by the cross piece 183 of the bracket 177 already'referred to. (See Figures 2 and 8).

lioosely mounted on the counter shaft 180 is the hub 184 of a sprocket 185 having the laterally projecting drum 186 (Figure 8). Fixed on the shaft 180 is the hub 187 of a drum or the like 188 forming a support for clutch shoes.

Pivoted to the drum 188 are links 189 which pivotally support the shoes 190.

For actuating the shoes 190 of the clutch structure now being described for moving them into frictional engagement with the inner face of the drum 186, there is slidably mounted on the shaft 180, a cone-shaped hub 191 having` the annular slot 192 into Iwhich project the fingers 193 from a yoke arm 195 fixed on a rock shaft 196 extending alongside the machine. Near each end of the man chine, the rock shaft 196 has the upright arms 197 by which it may be rocked and actuated for controlling the clutch.

It will be seen that when the clutch just described is thrown into its operative position, motion transmitted to the sprocket 185 by the chain 198, which travels on said sprocket, and on an aligned sprocket 199 on the shaft 173, will be transmitted through the drum 186, the shoes 190, the links 189, the drum 188 and the hub 187 to the Shaft 180.

Motion is transmitted from the shaft 180 to the shafts 31 and 35, which carry the spur feed wheels 32 and 36 in the following manner:

0n the shafts 31 and 35 are sprockets 200 and 201. (See Figures 1, 2 and 7). On the shaft 180 is a sprocket 203 shown in Figure 45 and arranged in alignment with the sprockets 200 and 201.l A sprocket chain 204, shown in Figures 1, 2 and 5, travels on the sprockets 203 and 201 and 202 for transmitting motion from the shaft 180 to the shafts 31 and 35.

Below the forward part of the bed 17 is mounted a stub shaft 205 on which is a spur feed roller or wheel 206, which projects upwardly through a hole 207 in the bed 17 just below the roller 52 and is designed for assisting in advancing the core stock.

@n the shaft 205 in line with the sprockets 201 and 202 is a sprocket 208 over which the lower strip of the chain 204 travels, (see Figures 3 and 5) for thus transmitting motion to the feed spur roller 206.

On the left-hand Yend of the shaft 87 is a sprocket 209 aligned with, a sprocket 210 on the shaft 180. -(See Figure 1). A sprocket feed wheel 89.

0n the right-hand end of the shaft 88 is a sprocket 212 in line with a sprocket 213 on the shaft 180. `(See Figure 4). Achain 214 travels on the sprockets 212 and 213.

At the rear of the machine is mounted a counter' shaft 215.- On theshaft 173l is a pulley 216 in line with a pulley 217 on the shaft 215. (See Figure 2). A cross belt 218 travels on the pulleys 216 and 217.

Supported on thegluepot 152 is a bracket 219 which supports a shaft 220. (See Figure 4).r On the shaft 220 is a sprocket 221 in line with a sprocket 222 on the counter shaft 215,. Formed on the sprocket 221 is a drum-223 forming' part of a clutch mecha-v nism, such as that which has been described as on the shaft 180.

The clutch mechanism now under con'- sideration has the, member 224 similar to the member 188 heretofore described and provided with the shoes, not shown.

'I he clutch member 224 is fixed to the shaft 229. The shoes of the clutch member are actuated by a cone device 225 similar to the cone member 191 heretofore mentioned. The hub of the cone 225 has the annular groove 226, receiving the fingers 227 of the fork 228. The fork 228 is carried by a longitudinally slidable shaft or rod 229 shown in Figure 4. A spring 230 is arranged on the rod 229 between the collar 231 and the bearing formed by t-he bracket 219. A lever 232 is pivoted on the bracket 233 and is vpivoted as at 234 to the rod 229. f

It will be noted that the lever 223 is at the delivery end of the machine,.so as to be readily accessible to the workman at the assembling table adjacent to the delivery end of the machine.

A chain 235 travels on and 222. Y

@n the shaft 220 is the sprocket 236 for the edge strip advancing chain 144, which has the spaced projecting fingers 238. The upper stretch of the chain 144 runs along the bed formed by the top 153 of the glue pot 152 and along the bed 141 to the front of the machine, where it travels over ka sprocket 239 on the stub shaft. 24() journaled on the bracket 241.

On the shaft 220 is an` edge strip advancing roller 242 having deep grooves wit-h comparatively sharp-edge strips, which Will not remove much of the glue from the edge strips.

On the shaft 220 is a grooved pulley 243 in line with a groovedpulley 244 on the shaft 1GO. (See Figure 4).

A belt 245, which may be an endless coil thesprockets 221 machine.

spring, travels on these grooved pulleys for imparting rotation to the glue pulley in the pot 152. f

It will be `noted from the foregoing de,

scription that the spring 230 normally holds the clutch structure 223, 224 andso forth out of operative engagement. vBy pulling-on the lever 232, the clutch can be thrown into engagement. v

In order to then hold the clutch automatically in engagement and to subsequently automatically throw-it out of engagement, the following means are provided:

A rock shaft` 246 is bracket 219. Upon this rock shaft is mounted a lock finger 247, shownin Figures 4, 11 and 12, adapted to rest by gravity on the hub 248 ofthe yoke 228, 'and when the rod 229 is pushed to theright for throwing the clutch into engagement on the shaft 220, to drop behind the hub 248v for thus holding the clutch in. a

0n the shaft 246 is a. trip linger 249, which. stands adjacent to thesprocket 236, as shown in Figures 4`and 11. l The trip finger 249 has a beve-led fac-e 250 adapted tobe. en-

It will thus be seen that when the lever.

'Ihe racks 256 are supported on the angle bar 141 by upright members 257-and braces 258. v 'l In Figure 17, I have shown the general arrangement of thek machines with relation to the assembling table 139.

completed are assembled on the table 139.

The rack 256 is used for edge strip stock.

I will now `describe somewhat in detail the voperation of my improved veneer core Two operators are used with this machine. One works at the front of the machine and is called the feeder while the other works at the rear alongside the assembling table 139, and is called the assembler.

In Figure 16, I have shown an assembled door sti e comprising the core stock members 253 and the edge strips 254.

In building up the core for veneered door stiles and the like, it is necessary to glue up a group, generally two o-r more rows of blocks 253 between itw'o edge strips 25'4. The core stock 253 may be of any length while the edge strips are the full length of the desired stile.

The material for the core stock blocks 253 is placed on the table 16. The feeder takes the pieces one at a time, places them on the bed 17, adjacent to the guide 18, runs them under the feed roll or wheel 32 to the saw a-nd'under the feed roll 42. The block 253, which has been cut to width, then passes under the roller 52 to the guide mechanism.

It will be understood that the core stock is dressed to thickness though the thickness is not necessarily uniform, before it is placed on the table 16. The saw 20 rips the blocks to width. The bala-nce of the block is guided to the left by the member 54 and if of sufli cient width is taken by the feeder and again sawed. Pieces too narrow for further use are permitted to drop oif the bed 17 onto a conveyor for instance. The feed rollers 32, 36, 206 and 52 feed the core stock blocks to the guide mechanism on the turret plate 55.

If the stock is to be fed straight through, the machine is set by removing the screw 63, turning the turret plate 55 until the guide passage 61 is up and then re-setting the screw 63. The succeeding pieces of core stock force the advanced pieces through the guide to the bed 70.

If it is desired to give to the stock a quarter revolution between the beds 17 and 70, the turret pla-te 55 is turned over a half revolution until the yokes 65 are up, as shown in Figures 5 and 10. As the stock then passes through the yokes and the springs 66, it is given a quarter turn.

The stock is forced in a continuous succession of single pieces along the bed between the guides 99 until the piece under consideration reaches the feed rollers 89 and 90.

The core stock is fed along the bed 70 under the feed wheels 89 and 90 to the top dresser head 98, which planes or dresses the top surface and thence to the lower dresser head 126, which planes or dresses the bottom surface.

The shoe 108 holds the stock against upward movement during the latter process.

Stock is then fed over the bed portion 70a to the glue roller 136 over which it is held down by the roller 164.

Stock is then fed to the small table 260,

which is attached to the machine and over-V hangs the assembling table 139. Each piece has one edge glued.

rllhe assembler selects the pieces and arranges them, building them up in two rows of blocks in the form illustrated in Figure 16. may have the glue 255 at their outside face and the blocks of the other row, as indicated at C have the glue 255 adjacent to the row B.

The assembler may then take an edge strip from the rack 257 and place it against the row B, as shown at the left-hand side of Figure 16, and then to get the edge strip for the other side of the stile, he pulls the lever 232, which throws the edge strip handling mechanism into gear by throwing the clutch on the shaft 220 into engagement.

One of the lingers 238 on the chain 144 engages the bottom piece of stock in the hopper formed by the members 145, 146, 147 and 148, moves it along the bed 141 to the glue roller in the pot 154 and delivers it with one face glued to the assembling table, adjacent to the partly assembled stile, and the assembler places it against the right side of the row of blocks C with the glue 255 adjacent to the row C, and shoves the inished assembled stile as far forward it can go on the table, and then commences the assembling of another stile.

It will be remembered that when the lever 232 is actuated, the yoke 228 moves to the right, whereupon the finger 247 drops behind the hub 248 for holding the clutch on the shaft 220 in gear until one of the fingers 238 on the chain 144 engages the trip arm 249 for rocking the shaft 246 and raising the locking linger 247 until it clears the hub 248, (see Figur-es 11 and 12) to permit the spring 23() to release the clutch. Thus only one piece of edge strip stock at a time is delivered to the assembling table for use for the stile then partly assembled.

In actual practice, the assembler frequently pulls the lever 232 for securing the delivery of one edge strip upon the assembling table., and the mechanism for delivering edge strips automatically stops when the piece is delivered.

Then the assembler assembles the rows of the required number of core blocks, which are being delivered by the core stock handling mechanism. He then lays an edge strip taken from the rack 257 against the core.

As the stiles are built up and the assembling table 139 is filled, the filled table 139 is moved away and an empty one 252 is rolled into place. lVhen a table has been filled, the entire group of built-up stiles are clamped together and that tableful is removed and a second tableful started as before.

The blocks of one row indicated at B f such changed structures or use of mechanical equivalents, which may be reasonably included within their scope.
