SEVRN MADSEN, OF CLINTON, IOWA, ASSIGNOR TO CURTIS COMPANIES, INCORPORATED, F CLINTON, IOWA.

WINDOW-SASH-STILE MACHINE.

My invention has to do with a machine for manufacturing` window stiles.

Modern window Stiles have in their outer faces (referring to the faces farthest from the glass pane) a hole to receive a sash cordy knot, a comparatively narrow groove communicating therewith and extending longitudinally of the stile toward the top thereof and communicating with a similar wider l0 groove. rlhese grooves receive the sash cord and the wider groove is to receive the sash cord pulley when the sash is in its upper kyposition. The inner face of the sas-h, that is to say that which receives the pane of glass, yhas the rabbet for the pane of glass and the mold which gives to the window sash a better appearance.

It is the purpose of my invention to provide `a machine which will bore the holes mentioned, cut the grooves, dressthe outer face and mouldthe inner face ofthe stile in a series of operations all of which are `automatically performed.

More particularly, in this connection, it

f5 is my purpose to provide a machine of theV kind under consideration having a hopper in which the sash stock previously dressed on the front and rear faces and previously passed through the tenoning and mortising machines is placed. This machine has means for boring the lowermost piece of stock in the hopper, then pushing out the .lowermost fpiece of stock, subjecting it to saws or cutters which cut the narrow and wide grooves, then further' advancing the stock and dressing the inner and outer faces. It will be noted that I have called the yface on the inside of the window the front face and the face on the outside of the 4n-vrindow, the rear face for convenience in distinguishin from inner and outer faces in this specification. A further purpose of my invention is to `provide novel mechanism for accomplish-v ing the boring, grooving, cutting and dressing operation and for synchronizing these various operations.

Still another purpose is to provide. such a machine arranged with pairs of units, whereby rights and lefts vmay be cut and dressed at the same time, and in which by cutting 'rights and lefts at the same time,

I am able to simplify instead of doubling the machinery necessary and am enabled to Application led February 4, 1924. Serial No. 690,460.

handle and store the stiles in pairs with a minimum number of movements and a minimum amount of work.

For convenience, I refer to the hopper end of the machine as the rear end.

lVith these and other objects in view, my

invention consists in the construction, ar` rangement and combination of the various parts of my window sash stile machine, whereby the objects contemplated are attained,as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

For facilitating the understanding of the construction and operation of my machine, I will briefly outline the steps in such operation.

The stock is placed in the two hoppers manually or otherwise, as may be desired, after the stock has come from the mortising and tenoning machines.

rlhe liritoperation involves the boring Immediately thereafter the pusher bar engages the lower-most member in the pile of stile stock in the hopper and pushes it forward a perspectiveview of a winin the n'iacliine for the grooving operations,

whereby the narrower and wider grooves cnt. rThe stock is then advanced by a "speel up mechanism to the sticking' Unit wl Y )y the inner and outer faces of the stock are dressed and trued, after which the stockv is discharged from the machine.

The stock is stationary during the boring operation and is advancing during the grooving and sticking operations. The movement of the `stock is continuous though variable after the stock leaves the boring means. f f

ift. will be understood that the machine consists of a series Of units, to.-\vit :.hoppers.

mechanism and sticking units, andthat th Y initsare arranged in pairson opposite sides ofthe machine, so, that right. and left dressed in the sticking units.

that they are arranged for cutting r and lefts and are arranged slightly d ently in the machine with relation to the sides thereof.

Before describing the machine and its operation, l will refer to the ii-'indow sash illustrated in Figures 21, 23 and where l have used the reference numeral 1U to indicate generally the stiles of the sash.

The stiles of the top sash and bottom sash are slightly dili'erent in respects, which L-.re not now important.

lt will be noted that l have called the face A the outer face, the face il the inner face, the face C, which is on the outside of the window when installed, the rear face, andthe face D the front face. rlie use of these reference characters will be convenient in referring to the operation of the machine.

.ln the outer face of each stile near tho upper part thereof, it is the custom to bore a hole l1 to receive the sash cord knot. rlliis hole has its axis inclined slightly upwardly, as shown for instance in Figures 21 and Communicating with the hole and extending upwardly longitudinally of the outer face of the stile 10 is a comparatively nari-on' groove 12 lo receive the sash cord, which communicates lwith a longitudinally upwardly extending wider groove 13 to receive the sash cord and also to receive the sash cord pulley, which projects into the chan- Frame.

The frame ol my machine includes a base 20, shown for instance in Figure 1, and a plurality of upright members 2l suitably located and arranged to support the mechanism.

The rear part of the machine is provided on each side with a table 22, which supports the stock during its movement from the hopper to the sticking units. are spaced from each other laterally, so as to leave ample room between them for the mechanism hereinafter' referred to.

Hopper.

@n each side of the machine the rear end thereof, there is provided a hopper. The hopper has an innel` Wall 23 with an The tables angle iron 24 at its forward end having an outwardly laterally extending flange 24; (see Figures 1 and 2), which forms the front end of the hopper. Y

The flange 242l is cut away at its lower endV as at 24h (see Figure 1) a suflicient distance above the table 22 to permit the bottom stile 10 of the stile stock in the hopper to be slid forwardly from the hopper.

The rear wall of the hoppel` is formed by `an angle iron 25, having one flange extending f transversely of the machine and one flange extending longitudinally of the machine in a plane parallel with and spaced from the outer face of the wall 23, as shown for instance in Figures 1 and 2. The angle iron frame member 25 of the hopper is adjustably mounted on the table 22.

Adjustably mounted on the table 22 near the front end of each hopper and spaced from the wall 23 is an upright bar 26 shown for instance in Figure 1.

The transversely extending flange of the angle iron frame member 25 terminates above the table 22, as shown in Figure 6, for allowing free movement of the stock pusher bar hereinafter referred to.V f

The frame members 25 'and 26 are mounted for lateral adjustment and longitudinal adjustment on the machine, in the following manner:

An angle iron 27 is mounted on the table 22 spaced from the wall 23 with a horizontal flange resting on the table and extending away fromr the wall 23, as shown in Figures 1 and 6, and with a vertical flange. In the horizontal flange are laterally elongated slots 28 to receive locking screw bolts 29, whichl are screwed into suitabley holes 3() in the table 22.

The angle iron 27 may be thus adjusted laterally by loosening the screw bolts 29, adjusting the angle iron, and then fastening the screw bolts.

The bar 26 and the outer flange of the angle iron 25 are provided with plates at their lower ends, as at 31 (Figure 6) which rest on and may slide upon the vertical flange of the angle'iro'n 27.L 'A screw bolt or the like 32 is mounted in each plate and projects' outwardly. Mounted on the screw bolt is a yyoke 33, having one arm bearing the case of the frame memberV 26).

, f mounted on the outer end ofthe screw bolt 32, as shown in Figure 6, and itis seen that by .tighteningthenun thek members 25 or 26 may be clampedA to the angle iron 27 in various positions of longitudinal adjustj ment thereon. 'This longitudinal adjustment of the angle iron frame member 25,

forming the rear end of the hopper is imjustable-for dierent widths and different n lengths of stock.

Boring mechanism.

The lower piece of stock is bored for the hole which receives the sash cord knot while lying at thebottom of the pile in the hopper. I will now describe the boring mechanism and in connection therewith some of the power and operating mechanism of the machine.

Suitably supported on the base 20 near the rear end of the machine is a power unit, such for instance as vthe electric motor 36, which drives a longitudinally arranged shaft 37', shown in Figures 1 and 3 mounted in bearings 38v and 39.

On the shaft 37 is a belt pulley 37a-shown for instance in Figures 1, 3 and 7, from which the boring drills are rotated. The drills for boring the holes 11 are supported in the following manner: A frame 37", the general shapeof which is indicated in F igure 2, rests on certain of the uprights 21 with its ends just under the table 22'. Between the frame 37b and the tables 22 are filler blocks 37, shown in Figure 7. On the rear part of the frame 37 are mounted beds 37d, forming generally the shape of a forwardly opening V. The beds 37d have tongues 372 extending downwardly Vinto slots 373 in the member 37b. Filler blocks 3741:2t of various thicknesses may be selectively employed between the beds 37d and the member 37 for holding the drill carriages at the proper height. are drawn tightly against the filler'blocks by means of threaded studs 374.'J on which are nuts 374. VSlidably mounted on the two opposite beds 37b are the drill supporting blocks 37e, illustrated for instance in Figure 7. Each block 37e is provided at both .ends with a'journal 37 f, in which is journaled a drill shaft 37g, to whicha drill 37hv is connected in an ordinary way;

Mounted on each drill shaft 37g between the journals 37f is a pulley 37. A belt 37j is extended around the lower part of the pulley 37 1 and thence upwardly and around the two pulleys 37i andl thence downwardly around the idler pulleys 37kfmounted on brackets 371 fory vertical adjustment. It will be thus seen that the pulleys 37i and the drill bits 37h are rotated from the pulley` 37". The blocks 37,e slide on the beds'37d for The drill vcarriages f the purpose of moving the drill bits to operv i ative position and the sliding movement is accomplished in the following manner:y

Pivoted at laterally spaced points on the blocks or carriages 37C.

sage of the drill bits to position for boring the lower piece of stile stock, when the drills are slid outwardly for Ythe boring operations.' I

For effecting the outward movement of the arms 37m and the consequent outward movement of the drill carriages and drills, l have provided the following means:

Suitably mounted on uprights of the main frame is a transverse shaft 3?'3, having l a slightly reduced portion el, shown in Figure 1l, upon which there is mounted for rotation the disc 37 having a clutch face 37v on one side. A coactingy clutch member 37W is-slidably but non-rotatably Amounted onthe reducedportion 3Tt of the shaft 37*s in position to coact with the clutch face 37V. The clutch member 37W is provided with an annular groove 37X. A collar v37,y has a screw-threaded connection with the portion 3Tt of the shaft 37s as shown in Figure l1.r Arms 37Z aie secured to thecollar 37Y by bolts 38a vand have portions 38b projecting into the groove 37X. Secured to the collar 37y is a handle or the like 38c forv rotating that collar for moving the clutch member 37W into or out of engagement with the clutch member 37" on the disc 37u.

If itis desired to operate the machine Without operating the Lboring mechanism, the clutch members are disconnected, soV that the disc 37 will not'rotate.

On the shaft 37S is mounted a gear 38l in 'mesh With a gear 38e on a suitable mounted transverse shaft 37f. '(Figure 3).

'The shaft 38i is operated from'the shaft'49 by means of a beltr 38grtraveling on ia belt 38i on the shaft 49.V i

The shaft 37 (Figure 3).eXtends forwardly in the machine from the motor 36 and has on its forward end the xvorm40 meshing with the Worm Wheel 41 on a suitable mounted transverse shaft 42.

Keyedto the shaft 4 2 are a series of pinion gears 44,45, 4G, 47, and 48, which are used in operatingthe boring and groove cuttingmechanisms at variable speeds.:

'Suitably mounted parallel with tliecross` shaft 42.is a jack shaft 49 shown 'in Fig@ uies 2 and 4. F iXed onthe shaft 49 is' a Wide gear 50. ,(See Figure .2), i

VSlidably `mounted ion thel gear 50 is a sleeve 52. An arm 53 fixed `tothe sleeve 52 projects laterally fi'on'rtlie side of the ymachine and has on its outer end a handle 54, shown in Figures 2 and 3. and used for imparting limited rotation t the sleeve 52.

Projecting from the sleeve 52 are parallel arms 55 between the outer ends of which is rotatably mounted an idler gear 56 on the short shaft 5,7. The gear 56 is in sliding mesh with the gear 50 and yis designed to selectively mesh with any of the gears 44, 45, 46, 4T or 48. The sleeve 52 is slid longitudinally on the gear V50 for causing the gear 56 te mesh With the various gears -44 to 48 inclusive. *i

rlhe gear 56 standsabove the gears 50 and the gears 44 to 48 inclusive, as shown inv Figure 4, and may be .raised for enabling lit to be slic from a smaller gear of the series 44 to 48 to a larger gear thereof by ti ting it bynieans of the arm 54. Y

An ordinary belt tightener mechanism 58, shown in Figr-.rev 3, is provided for the belt 38g. @n the opposite sides of the disc 37 are cams 59,- Which engage the rollers 37p.

Before proceeding with the furtherde`V scription of the machine, l Will briefly outline the operation of the boring drills.

Assuming` thatrstockV is in the` lioppers and that the motor 36 is started. it will be seen that the shaft 37 (Figure 3) will .be rotated and through.Y the Worin V40 rWill rotate .the Werm ivheel 4l on the shaft 42 and the `shaft 42 vand the gears 44 to 48 thereon. rlhat one of the-gears 44 -to 48, which is in mesh With the gear 56 (see Figures 2 and 4) Will Vrot-ate such gear 56, which in turn imparts rotationl to the-Wide gear 50 and the shaft 49. Rotation of the shaft 49 is imparted through the pulleys 38I and 38h-'and the belt 38g to the shaft 38E and the gear38e`thereon. The gear 38e. rotates the gear 38dY (see Figure 7) and the shaft 37S. the clutch meinber38W and the disc'371. (See Figure 11.)

rEhe drills vare Vrotated from the. pulley 37a by means of 'the belt'37j vtraveling over Y through the openings 37T into the lower stile 10in the stock in the hoppers for boring ythe holes l1 in the right and left stiles in the respective hoppers.

As soon as the'cams 59 clear-the rollers 37e, the springs 3715Withdravv the drill bits.

The next operation consists in sliding the lowermostVV stile members 10 in which the holes l1 have been bored out-*ofthe hopper,

`advainiing them to the groove cutting inembers and cutting the grooves."

I will 'now describe the means for movingthe stiles out of the hoppers.

Pusher bar for sliding 'the .st/Zes from the kappers.

Mounted oneach table 22 at the rear part of each hopper is a push bar 60 (see Figures and 6), having in its under side a down- 65 has a tapered head 66 received in the slot 61 in the pusher bar and has its shank eX- tended through the block 63.

`A lsleeve-shaped nut 67 is screwed onto the lower end of the screw bolt 65 for clamp-` ing the pusher bar 60 and the block 63 together. The reduced portion 64 of the block 63 is of sufficient height to prevent binding between the pusher bar and the block 63 and the table, but to permit the vpusher bar and the block 63 to be tightly j locked together. Y

The nut 67 has a downwardly projecting shank 68 through which extends a pin or cross bar or the like 69 for convenience in rotating the nut 67.

yThe block 63 has a projecting arm 70 in which is mounted a shaft 71 with which is connected a reciprocating link 72. (See Figure 5.) Fixed to a shaft 73 journaled in two of the upright members 21 is an operating channel bar 74. which at its upper end is pivoted to the link 72 at 75. Mounted onthe gear 38d is a roller 76 which projects into ythe channel-shaped operating bar 74. (See Figures 3, 5 and 7.) On the other side of the machine, a lever 74@ is fixed to the shaft 73, and is fixed to the link 72 on Ythat side.4 I

Portions of the walls of kthe channelshaped operating bar 74 indicated at 78 are curved on the arcs of circles, having their centers at the center of the shaft 38t on whichr the gear 38d is mounted for a purpose, which will be later referred to.

Assuming that the parts just described are in their positions shown in Figures 3 and 5, just after the cams 59 have passed the rollers 37p and the boring drills have been withdrawn and that the gear 38d, (shown in Figure 5) is moving in a clockwise direction, and that the pusher bar is at the rearward limit of its movement. withits forward end adjacent to the rear end of the lowermost stile 10, the further rotation of the gear 38d will carry the operating channel bar 74 forwardly in the machine, drawing with it the link 72, the block 63 and the pusher bar 60, Y

The pusher bar 60 lwill engage the lower stile 10, sliding it forwardly on the `table 22 under the fiange 24a of the angle iron 24 to position for the grooving operation.

On the forward end of each hopper, there is mounted for loose vertical sliding movement a heavy weight 79, which, as shown in Figures 1, 3, 8 and 9, is hung by means-of a screw bolt 8O and adjustable nut 81 thereon on a bracket 82, and is held against horizontal movement by bolts 83 extended through vertically elongated slots 84 and having washers 85 thereon.

illecita/mism for cutting sash pulley grooves.

I will now describe the mechanism fox,` cutting the grooves 12 and 13 shown in Figures 21 to 24 inclusivein the stile.

On each side of the machine forwardly of the hoppers, there is -pivoted for sidewise swinging movement a downwardly opening A-shaped frame 86, having its arms connected near their lower ends by a cross brace or frame member 87 as shown for instance in Figure 3.

These frames are designed to carry at their upper ends the grooving cutters and are designed to be swung laterally for moving the grooving cutters to operative position and vice versa.

Supported from the frame member 87 is a gear casing 88 shown in Figures 1, 3, 8

and 10. Fore-and-aft spaced upright shafts 89 and 90 are mounted in the gear casing 88, the frame member 87, and are journaled in ther upper end of Vthe frame 86, as shown particularly in Figures 3 and 8.

The rearward one of these shafts carries on its upper end the grooving cutter 91, while the forward shaft 90 carries on its upper end the somewhat wider grooving cutter 92.

On the lower ends of the shafts 89 and 90 in the gear casing 88 are helical gears 93 and 94, both of which mesh with an idler helical gear 95, also mounted in the gear casing 88. (See Figure 10.)

0n each shaft 90 is a belt pulley 96, which is operated in the manner hereinafter referred to.

It will at this time, however, be obvious that upon the rotation of the shaft 90 through the belt pulley 96, the gears 94, 95 and 93 will be rotated for rotating the shaft 89.

The frames 86 on the opposite sides oi the machine are connected together by a powerful coil spring 97, shown in FiguresL 2 and 8 for instance, which yieldingly tends to hold them inwardly where the grooving cutters 91 and 92 will be out of the path of travel of the stile stock.

At the inner edge of each table 22 is a plate or strip or the like 98, shown for instance in Figures 1, 2 and 3, serving as a ure 3 trat alter the disc 37u moving in cl n'iovcment or' the trames S6 ant; the sh 5:19 and 90 and the groot-.fing ci t "s 91 an@ rried by said shafts, there is provided Vfflowing means:

'forward tace ot the boJe referred yto which supports `the 87m andA the boring drills', there d two downwardly hanging arms l shown r'or instance' in lig'u es The lower ends ot the arms rollers 101 on pintles or short shafts rThe llower end ot each arm 100 is pivot a longitudinally adjustable vlink 103, nl" in turn is pivoted to one of the trames The periphery of the disc 37 he referred to is provided ior a suhstai tion ot itslength with a 10-1- 1 to travel between the rollers 101 its edges taperedvwhere it lirst finally leaves the rollers 101, as at Figures 3 and 8.

1t will be noted from the showing wise direction carries the Acams'59 past rollers 37p (see also'Figure 2) and wn e roller 76, shown in dotted lines in and also illustrated in Figure 5, is act1 the bar 74 for operating the pusher hai advancing the stile stock, the cams Yl0-l enter vbetween the rollers 101 Vtrfcing apartl and thrcgh the links 103,'swiir mg the frames .S6 outwardly or laterally l causing the' grooving cutters 91 and 92 to swing to position lor vcuttir'ig the grooves 12 and 13. (See Figures 2,3,8 and 21.)

Owing to theirl relative location lonnitrdinally of the machine, it l'isV obviousY that narrow cutter 91 will cuta narrow groove lirst and that the wider cutter 92 will subsequentlyv engage the same pieceoiu stock and will make its wider cut during the tinis'hing of the cut of the groove cutting meinber 91.

` It is also obvious that sincev the ycutters 91 and 92 are withdrawn from operative position at the same time, that the wide groove 13 will be shorter than the Jfull length ot the groove cut bythe cutter 91.

As soon as the cam 10apasses from be- Y tween'the rollers *10, the spring 97 will 4me 371 hereincase-'o versprings 106Y and 107 designed to yieldingly press the advancing stile stock against the guage or stop member 98. (See Figure 2). V

curved shape ot' the walls 78 ot the chanbar operating member 74, to which I nave heretofore referred.

it is noted that during the operation of the machine, the gear 38d, which actuates tue har is in continuous operation. lt ay =lso benoted that it is desirable that the ierbar actuating from the operating lhould be stationary at its rearward lll on hereinbelfo're referred to. he pusher is lett stationary on account ot' the 'curva-ture ot' the wall portions 78, which kes possible for the roller 76 to travel p Vare to its position shown in full lines in Figure 5 .vithout imparting any movement to the bar 7 l.

The further movement or the roller 76 1 will now lexplain the reason tor the" t ci movement during the boring opertely from the point A108 shown in upon the continuation ol the rotation of the 38 actuates the pusher bar 60 `for advancing the stock, and this advancing movement is continued until the grooving operation is completed.

l i'ind it desirable to give to the stock a quicker movement toward the speed-up mechanisnnto which will later refer, after the grooving operation has been completed, and'this is accomplished during the downward n'iovement of the roller 76 between the 'curved wall portions 7 Strom the position shown at 109 in dott-ed lines in Figure 5 to pproximately the point marked 110 in said wure.

pusher bar 60 should be quicker than its advancing movement in order to maintain the maximum' speed of operation of the machine, and this is accomplished by the arrangement oi' the operating bar 7land the gear 38d and the roller 76, whereby the roller 76 is ia'rther from the pivot point 73 during the advancing movement of the pusher bar 60 and substantially closer to said pivot point during the return movementv of the pusher bar.

Speed up mechanism'.

for carrying the stock to the sticking units. l

The speed up mechanism is especially illustrated in Figures y12, 13 and 14.

Mounted on each side of the machine on certain of the uprights21 is a longitudinally arranged supporting bar or the like 111. The bars 111 on the opposite sides of the machine are located just below'the tables 22 and are parallel with each other and carry a pairk of transverse spaced shafts 112. On

n ward pressure on the arms121.

the ends of the shafts 112 are rollers 113, which project through'suitable slots 114 in the tables 22.

lt may be said thaty the bars 111 are mounted on the uprights 21 bymeans of the bolts 115 screwed into the uprights 21 and extended throughvertically elongated slots 116 in said bars 111.

Below they bars 111 are projecting lugs 117 extending from the uprights 21 and having adjusting screw bolts 118 therein, as shown in Figure 13. The shafts 112 extend across the machine andare common to the speedup7 mechanisms on the opposite sides of the machine.

The rollers 113 project upwardly through the tables 22 just enough so that the stock may travel properly on them.

' The upper rollers for coacting with the rollers 113 and for gripping, holding and advancing the stock in cooperation therewith are mounted as follows:

Supported .on and extending upwardly from the outer edges of the tables 22 are brackets 119 which support a transverse shaft 120 extending across the machine.

On each side of the machine arms 121 are pivoted on the shaft 120 Vand extend rearwardly in the machine, and arms 122 are pivoted on the shaft 120 and extend forwardly in the machine. j Y f The arms 121 support atransverse shaft 123 extending across the machinefand the arms 122 support a transverse shaft 124 extending across the machine. has rollers k125v on. yits ends above the rearward rollers 113 and the shaft 124 has similar rollers 126 on its ends yarranged above the forwardY rollers Y113.V Y

f The arms 121 are spring-pressed downwardly in the following manner:

Screw bolts 127 are screwed into .blocks 128 mounted in the inner edges of the tables 22 by means of bolts 129 andfextend slidably through lugs 130 on the arms 121. Springs 131 arranged above the lugs 130 on the bolts 127 and between said lugs .and the heads of the bolts exert a yielding down- An adjustable stop for limiting the downward movement of said arms is provided 1n the screw bolts 132 mounted in the arms,

121 and adapted to coact with wear plates on the blocks 128.

Mounted on each arm 121 adjacent to the The shaft 123 y Figure 12, which stands just enough above the level of the lower part of the roller 125 to clear stock traveling under such roller, but close enough to the stock, so that when the rear end of one stile passes under and clears the lower side of the roller 125, the yshoe 134 will drop upon such stock, as shown in Figure 12, and prevent the roller 125 from rolling over the end of the stock and tearing the edge thereof, because of the corrugated surface of the roller. l

The blocks or strips 128 are arranged to serve as a gauge or back stop for the stock in the same manner as `do the members 98 already referred to.

The stock before it leaves the springs 106 and 107 is engaged by springs 135, which hold it pressed inwardly against the blocks or strips 128.

The speed up mechanism is operated in the following manner: Y i

On the shaft 42 hereinbefore referred to and shown in Figures 1, 2, 3, 4 and 14 is a sprocket 136 in line with another sprocket 137 on the shaft 120. (See Figure 14). VA sprocket chain 138 travels on the sprockets 136 and 137 for transmitting rotationto the shaft 12() from the shaft 42. (See Figures 2 and 14). The chain 138 also engages an idler gear 139 on a stub shaft 140 arranged below the gear 137 with the stub shaft 140 above the level of the shafts 112.

On the shafts 123 and 124jare sprockets 141 and 142 shown in Figure 14. On the shaft 120 are sprockets 143 and 144 (see Figures2 and 14) which are aligned with the respective sprockets 141 and 142.

On the sprockets 141 and 143 a chain 145 travels and on the sprockets 142 and 144 the sprocket chain 146 travels for transmitting rotation from the shaft 12() to the shafts 123 and 124. Y v

e On the shafts 112 are sprockets 147 shown in Figure 14. On the shaft 120 is a sprocket 148 andon the shaft 140 is a sprocket 149, the last four sprocketsbeing in the same plane. A chain4 150 travels around the sprockets 147 and overthe sprockets 148 and 149 as shown in Figure 14. The sprockets 139 and 149 are idlers.

It-will-thus be seen that motion is transmitted from the shaft 42 to the sprocket 13G and thence through the chain 138 tothe sprocket 137 and the shaft 120. From the shaft 120, motion is transmitted through the f sprocket 144, the chain 146 and the sprocket n Motion is transmitted from the shaft 12o to the shafts 112 through the sprockets 147 roller thereon is a shoe 134, shown inand 148 and the chain 150.

nds of 'theft-tables Q2, channels 151, shown in Figures 1, 17, 19 :i O. are provided arranged with the bottom o" the channels slightly below the level ci the tables. 1

Mounted on transverse shafts 152 and 153, shown tor instance in Figures 1 and 17 are tm hier sprockets 154 and 155, the arrange- "i uit of the sprockets on both sides of the chine beingl the saine, and the shafts beingv extended across the machine.

On each side of the machine, a conveyor chain 156 travels around the sprockets i5 and 155 through the channel of the bed 151 and varound idler rollers 157.

On suitable upright members of the main r.trame are mounted transverse trame members 158 and 159, each substantially 1 rectangular'in outline. These trames 158 and 159 have bolted thereon on each side of the machine upwardly projecting` supporting ar1ns'160 and 161.

Mounted for vertical sliding adjust-ment onvreduced upper ends 'of the arms'160 and 161 are sleeves 162l shown in Figure 17. lfiounted on the yr'duced upper portion of each arm 160'and 161 above the sleeve 162 isa coil spring 163 held in place by an adjustable nut '164,4 shown for instance in Figure 17. 'i Y Formed on each sleeve 162 is a' horizontal journal 165. Shafts 166 have cylinders 167 eccentrically arranged thereon andv mounted in the journals 165 of the laterally opposite sleeves '162.

At each side of the machine, the frame member 168, shown for instance in Figures 17 and 20, is supported on the outer ends oi tlie'shafts 166. l These frame members 168 extend longitudinally in the machine.

Supported at the klower edge of each trame member 168 is a downwardly opening; channel bar or the like 169, serving as a the endless vchain hereinafter whicl-i at outer 'end has a nally the machine a bracket or the like 176 'shown for instance in Figures 1 and 20,

@n the shafts .17 above the tumbler sprockets 154 are mounted tumbler 4sprockets 177. l

@n the lo'ngitudinallj..T aligned tumbler sprockets on each side vot the machine is a chain178, thelower Stretch of which travels inthe downwardly opening` channel-shaped guide 169.

Guide plates 179 are secured to the lower Vwalls of vthe guide 169, as shown in Figure 20, by nrc-ans of screws or the like 180 and overlie the. channel portion o't` the guide, so as to support the links ot the chain 178, as shown in Figure Q0, so that the lower stretch oit said chain will be held in horizontal position during the operation of the mach-ine.

Secured to the links of the chain 17 8 are rubber pads 181, shown in Figures 17 and 20, which can be detachably mounted byy screws 182. The chains 178 and 156 coact for advancing the stock through the sticking unit and past the dressing cutters in a manner hereinafter again referred to.

Owing to the Vfact that there are some variations in the thickness of the stock sent through the machine, it is desirable to be able to raise or lower t-he upper chain 178, and for this purpose, I provide the following means:

0n each shaft 166 between the chains 178, there is mounted an upwardly projecting, downwardly opening U-shaped bracket or the like 184, the arms ot which have journals 185 receiving the appropriate shalt 166. The brackets 184i are connected by a downwardly opening channel-shaped angle iron member 185, illustrated in Figures 15 and 20.

On each shaft 166 between the arms of the bracket 184 is mounted a worm wheel 186. A shaft 187 is journaled on the brackets 1841 and is provided with worms c lowered with relation to the sleeves 165 and the' frame of the Vmain machine, carrying with them the frames 168, the tumbler sprockets 177 and the chains 178.

lt will be seen that the brackets 184 and the parts carried thereby will be raised or lowered with the shafts 166.

For operating the chains 156 and 178, the following means are provided:

Pivot-ally mounted on brackets 1.90 on the base of the machine are rthe arms 191 of a forwardly extending yoke-shaped member 192. A lsimilar yoke-shaped member with forwardly extending arms, which member is indicated by the. numeral 193, and is shown in Figures and 17, is mounted on the yoke 192 for adjustment longitudinally of the machine. `This, is accomplished by extending bolts 194 'th-rough longitudinally elongated slots 195 in the yoke 193, as shown in Figure 17, and by mounting said bolts in the yoke 192.

In the forward vends of the arms of the yoke 198, there is mounted a shaft 196,

shown inFigures 1, 17 and 18.

The shaft 196 carries a sleeve 197 journaled in the arms of the yoke 198, as shown through the slots 198.

iny Figure 18. The sleeve 197 has in its central portion opposite longitudinally elongated slots 198.

Clutch members comprising pins or the like 199 are extended through and fixed to the shaft 1.96 and project through into or The sleeve 197 has looseljT mounted thereon sprockets 200 and 201 of different sizes which haveV clutch faces 202 adapted to coact with the pins 199 when the shaft 196 is slid longitudinally in the sleeve 197. y

rEhe shaft 196 is pivoted by means of a lever 203, shown in Figures 15 and 18, at one end and having a portion projecting into a groove 'or slot 204 in said shaft.

1t will be seen that by means of the lever 209 the shaft 196 may be moved to neutral position or to its positions where it is locked to the sprocket 200 or thesprocket 201 as may be desired.

The shaft 196 is operated from the shaft- 42 by meansof a sprocket chain 205 traveling on a sprocket 206 on the shaft 42 and a sprocket 207 ixedon the sleeve 197 and sl'iown Figures 1.5, 16 l "i,

@n the rearward. shaft spaced sprockets 208, which are aligned with similar sprockets 209 on thefshaft 159 and with the respective sprockets 200 and 201. 1 chain 210 (Figure 19) travels around the sprocket 200 and ther upper aligned sprocket 208 and over the front face of the aligned sprocket 209, and a similar chain 211 travels over and around the sprocket 201 and around its aligned sprocket 208 and over the front face of its aligned sprocket 209, as illustrated in Figure 17.

1t will thus be seen that through the chain 205, the shaft 42 transmits rotation to the sprocket 207 and the sleeve 197, and that rotation of the sleeve 197 is transmitted through ,the respective sprockets 200 and 201 to the shafts 153 and 172.

1n order to support the sleeve 197 in proper spaced relation from the shaft 172` suspension rods 197 are provided, pivoted to the member 193 and to sleeves 1971) loosely mounted on the shaft 17 2.

The adjustment of the clutch pins 199 determines whether the sprocket 200 or the sprocket 201 shall be the active driving` sprocket andV thus determines the speed of the shafts 152, 158 and 172 and the kchains 156 and 178 carried thereby.

The first dressing cutters of the sticking unit are operated from motors which are mounted in the following manner:

Slidably mounted on the frame member 158` at each side of the machineisa frame or supporting member 212. Each frame member 212 has a screw-threaded connection with a transversely mounted rod 213, as shown in Figures 17 and 19. The rod 21B is journaled in the end of the frame 158 and has a hand wheel 214 on its end for effecting lateral adjustment of the frame member 212.

Mounted on each frame member 212 inwardly in the machine with relation to the chain 156 is a frame member 215, which supports a motor 216. rEhe frame member 215 is mounted for vertical sliding adjustnient on the frame member 212 and its position is varied by means of an adjusting screw 217 mounted in a. bracket 218 on the frame 212, as shown for instance in Figure 17. n

Mounted on the arbors of the motors 216 are critters 219 for dressing the outer faces i of the stile stock. (Figures 1, 15 and 17.) Theframe member 159 is longer than the frame member 158 in order to support illsimilar to those described in connection with the motors 216, and similarly mounted and adjustable.

On the arbors of the motors 220 are the cutters 221 for dressing the inner faces ot the stile stock.

l have iound that l have enough surplus power from the motors 216 to j ustiicjv operating' the pulleys 96 on the shafts 90 hereinbefore described from the pulleys 222 on the shafts ol the motors Qltby n'ieans of the belts As the stock passes from the speed-up77 mechanism chains, it is seized betiveen the chains G and i778 and carried past the cutter Q19 by which the outer tac l having the grooves l2 and 13 and hole ll thereon. is dressed, and then aast the cutter B2i b v vfhich the inner iace is dressed to torni the ralzfbet la. smooth rib 1S, molding 1 7 and the quirk 1Q.

l shall now reifer to the operation ol the machine a whole` and explain some or the advantages ot such a machine. The constiuction and relative arrangement ot the parts Will be perhaps made clearer during the explanation of: the operation ot the machine.

Operation of he moda/ne of sash stile stock is placed in c ln the right-hand hopper, as illustra* instance in'Figures l and 25 the stile is with front face down and its inner toivard the middle of the machine and 't top toward the .trent of the machine. i pile or' stile stock in the right-hand hopper will then malte right-hand stiles for the sash as the window is viewed Yfrom the inside ot a building).

Similarly in the left-hand hopper, the pieces of stoel; are laid front tace down, top toward the liront or' the machine, and inner 'face toward the middle of the machine for making lett-hand stiles.

The machine is started up and the cam disc 37 operated in the manner hereinbefore referred to, as illustrated especialljT in Fi ure 2, will rotate tor bringing the cams 5f) .ietiveen the rollers 37p for thus swinging the arms 3T outwardly and effecting the boring' operation.

As soon as the cams 59 clear the rollers or, the boring drill carriages are drawn back to normal position bvl the springs BZl. yThe dise 3.7 is shown in Figure 2 just alter the boring operation has been completed` It ma;Y be mentioned in this connection that the hopper :trame members 26 and l5 are longitudine-liv adjustable and the member 27 is adjustable lateralljT on the machine, so as to adapt the hopper to stock of difierent sizes.

the bor r operation, 'the roller 7G s iown in Figure 5 travels from the point tion for cut-ing the grooves l2 and l The pusher bar actuated by the bar Tll, shown in Figure 3, moves `torwardljY trom Y 1,

its position shown in Figure in full -ines to its dotted line position shown in seit tip;- ure for advancingv the lovfer piece o; to position for the groovina' operation.

lt ivilh of course, be understood that the pusher bar mechanisms are employed in ouplicate on the opposite sides ot' the machine tor moving' the stock out ot the hoppers.

At the finish ot the toi-Ward stroke ot the pusher bar. Ait is speeded up While the roller 7G moves from the position 109 to the position lll), shown in Figure 5.

The movement oit the stocl aitei" i to leave the hopper is continuous t the machine.

rlhe stock is advanced bf! the speed-up n'iechanism to position Where it is engaged between the pads lSl. on the chains 178 and the chains 156, by vrhich the stoel: is carried past the face dressing cutters o'l the stiel*- inpj unit.

yEhe inner and outer faces are l these cutters and the stoc-lr is discharged at the iront of the machine,

rlhe machine is more rapid and does :Caster Werl: than machines that are hand ted.

It is obvious that the automatic feed also does away with considerable labor. rl`he hoppers are readilv adjustable 'for handling all sizes ot stock.

The variable speed mechanisms enable the machine to be adapted to auch v ations in conditions arise in the factory.

E v using double units and sending rio'hts and letts through the machine at the same time, a number oi' advantages are secured. rlhe stiles are turned out in pairs and onljyT one counting' necessary. The stiles can be easily stacked in pairs. as thev are take from the machine?, Which facilitates the handling and reduces the number ot handlinn's nccessarj7 and makes it convenient tor the i'further Work Vin completing; the Window sash. f? iso or.
