The invention is illustrated in the form of a machine for-gmakingutoeth `brushes in which a base is provided for supporting a main 'frame of 'the -machine. The motive power for the machine is preferably obtained from a motor 10.5 which vby a belt drive shaft 10G. This shaft by w rm 107 and wormwheel 108 Vdrives what I .call themain shaft 109 running longitudinally of vthe machine. 'This shaft operates-'most of the `mechanism connected ,with -Jthe making i of the tufts.

.its has been statedthetuft-s are formed byforcing bunches ofbristiles into metallic cups. It has been described in `my above :mentioned patent liow'tlie1tiift ofi-bristles with its inetallic eup'iscut off and left 'in positionto be removed from'the'tnft making mechanism. For the purpose of-transferrinptheituftia transfer cam OO oscillates -aitranslfer `frame'about a shaft 4f, arranged longitudinally on the main frame. 'This frame '8 is provided neariits outer end 4with a llongitudinal shaft 298 having a "fixed head 299 carrying a fixed thin jaw plate 5. rlhis fjaw plate'hasa curved edge. Mounted on an oscillating studicarried'byfthis head 299 fis a :corresponding movable ljaw plate 8 having a curved edge. Theseftwo edges co-opera'te ,with eachie'therfto 'form jaws 'for engaging the tuft of bristles B. This'frame is=designedfto osillatefabout its shaft from the position in which the aXis'of the passage between rthe icurved edges of t-hetwo jaws is in -line ivi-th'the axisfof the bristle -tnft as it is beingut offfthe .wire. `Here a lcam 129.5 "on the :sh aft 298 engages a pin .296 to hold the shaft 'ii-n proper iposition.

ljaw closed.

jthejaws vert-ical. .wardly the posni-z The jaws first come to the position in which a tail 9 connected with the movable jaw 8 is still in Contact with a pivoted latch l0. Just as soon as this tail 9 passes over the end of this latch l0, a spring forces the This grips the tuft of bristles stated so that it can be moved away from the turret mecl'ianism after havii'ig'been cut off.

Theframe swings down to the position in 7 which the can. engages a stop to hold lluring this motion down- V in of the jawsischanged. The shaft 298 on wh'ch is carried the so called lined vjaw 5 is caused to swing to a certain position by a spring` i6 connected to the jaw at one end and with a hub in which the shaft has a hearing at theother. rl`his spring' holds the shaft bach and also holds it against rotation beyond a. certain point. This results in sliding the shaft 29S longitudinally and niovingthe jans 5 and S about this shaft as a center so as tobriug these 'fiat 'jaws into a position such that they moveedgewise with the oscillation of this frame. .The edge of the metallic cup is spaced slightly fromthe jaws and when the .jaws move yforward in the manner just described, the cup is intended to enter a hole in a brush blank C and the jaws ythen engagingzthe edge of the cup positively force the same in so as to insert it and cause it to bezheld frictionally therein.

The-spring l@ acts to force the shaft 298 bach. This withdraws fthe jaws from the tuft of bristles set in the brush yback and leaves the frame in a position to rise about its shaft at the next oscillation produced byiits c.. This transferring mecha not shown er claimed herein it is vfully shown and claimed in said original patent, tfmay beregarded a mea-ns for feeding theitufts tothe brush blank and setting them therein.

Bres/1 turret @Z9-wing' and 'indem/iig finecma gear w with a loose o; rotatable o- 9 verse index cin 1*'0 ing the groove 61 iu the clutch member Ndrmally the spring would hold theclutcli member closed. but when this roll moves into the end of the groove it draws the clutch member away and stops the rotation of the shaft- 53. The shaft remains stopped7 of course, until the shaft 58k is moved to withdraw the roller from position. A'. spring 622 (Fig. 7) keeps the roller in engagement with the clutch member so that it will automatically move into' this groove when the same has nearly completed a revolution.

Loosely mounted onthe shaft 58 is a locking arm 63 which.- whenthe arm 59 is drawn back, is movedwith it on account of 'a projection 64 on the latter extending' behind the arm 63. A spring 65 (Fig. 7) `Vacte Constantly to pull this arm toward the clutchso that when it is allowed to movein that direction by the arm 59 a wedge-shaped projection 66 on the back of the lockingarm4 will-engage in a longitudinalgroove'67 in the clutch member 55. he object of this is to provide for positiv-ely stopping the rotation of tl e clutch member just 'at the end of a complete revolution so that' 'the index clutch shaft 53 can rotate just once and then be forced to stop exactly on the right point.l

@n the shaft 50 there is a cam 70 which operates a cam roller 71 on a lever 69 freely swinging on the shaft 58. By means of an adjustable link 72 this lever is adjustably connected with a pawllevei' 73 rfreely pivoted on a transverse shaft 74. This lever carries a spring-pressed pawl 75 ladapted yto engage ratchet teeth on a wheel 76 fixed on the shaft 74. For each oscillation of this lever the Whe-el 76 will hev advanced' one step, which according to the adjustment will be the length of one tooth or a greaterl number as may be desired. In the form herein shown there are forty-seven of these teeth on the wheel and the wheel operates the widthv of one tooth at each-operation.

Rotatingwith the shaft 74 is a clutclioperating dog 77 which engagesl an arm 78 fixed to the shaft 58 and operates that to stop ther rotation of the'turret atvthe end of each con'iplete rotation of the shaft 74.

Securedr on thisshaft 74 is a lengthwise cam 80. This cam is provided with Aair-intermittent spiral groove 81" for receiving and controlling a roll 82 mounted on the end of a lever 83.v It will be obvious that the rotation of this cam will cause this roll to be moved step by step farther from the center. of the shaft 74 and the lever to be moved outwardly, intermittently. There are sixteen steps or motions to this cam and it takes three oscillations of the lever 73 and the advance of the wheel 76 three stepsto move the roller 82 from one level to the nextl onev in the form shown. The operation of the lever 83 in this manner turns a shaft 84 by means of adjustable studs 85`on the lever and a. plate 89 on the shaft. A lever 86 von the shaft 84 is thus moved. On this Vis mounted a pin yoke 87 having pins engaging between two flanges of a flanged wheel 88 located on opposite sides of the pinion 54 on the shaft 53. These iiangesengage the opposite sides of the brush turret index gear 116 and cause it together with the Whole turret, involving the parts 158 and 159 and the aws161 and 162 carried thereby to move along a shaft 111 on which they are rotatably mounted this shaft beingl stationary. The sleeve moves with them. The cuni has va slot 169 through which the end of the arm 171 moves' at this time. l

At the end of the spiral groove the roll 82 enters a notch in the end of a pawl 90. This pawl is provided with a long slot 91 through which it is pivotedon a screw 92 carried'by the cam and is normally held in the position shown in Fig. 13 by a spring 93. Just behind the rear edge of this pawl is a springpressed latch stop 94. As the cam rotates in the direction indicated the roller A82 will come out until, in the present instance at the 47th position, it enters this notch in the paw-l v9() and presses the whole pawl backwardly until the end of the pawl snaps `over the latch 94 and allo-ws the parts to move to the position shown in Fig. 15 so as to drop the roll 82 back'into its first position. The piessure being removed from the pawl it then snaps back into'the position shown in Fig. 13. This mechanism is for the purpose of feeding the brush turret longitudinally by a step-by-step'motion into sixteen different positions. It will be understood that in each one of these positions' certain operations are performed on the brush blank as will appear below.

Vertical tur/ret motion..

This part of the machanism if used alone would merely provide one line of holes or tufts inthe brush, but the machine is designed yand shown in these drawings is adapted to place three lines of bristle tufts and two extra ones at the endl making fortyseven in all. In order to accomplish this the shaft 74 is provided with a cross-wise cam 95. This is fixed to the shaft and is provided With forty-'seven steps thereon. These 1 llfi are divided into lifteenseries of three steps each, a low, an intermediate, and a high step in each case, and two additional steps constitutingthe last and next to the last in fthe series, but,fof course the arrangement would be different if a different numberof tufts were to be set in the brush. rlhesc steps are indicated by the numerals 1, 2, 3, f1, 46 and 47. lt will be understood that while the roller S2 is moving along one concentric surfaceduring the three advancing steps of the shaft, the roller 96 which rests on the cam 95 willlbe lowered from a high step to an intermediate one, andfthen to the I' low step of that series.

The effect of this rolleris as follows: lt is mounted on :remember-97 which is forked at the bottom'toguideiit about thc shaft .T 41k and at vits upper 'end a rod 98 connected with it vertically reci'irocates a rest Dilon the top of said rod on which the frame 4:1 rests, and consequently it raisesfand lowers that frame about its pivot shaft 2-/l'withall theparts supported' upon it. Starting from i the position marked 17 in llig. 16, when the roller 82 is in the position shown in full lines in Fig. Y13,the roller 96 is on the first of the high surfaces 1 of 'the-cam 95. The brush blanks held by the turret willbe lojcated in a position which may befrepresent-ed Drilling 'brush blank.

The first operation performed during this motion of the brush blank is the drilling` operation. NVhile this is taking place the blank is in the position marked drill.7 'lhe lever 69 which is oscillatably'mounted on the shaft 58 is connected wit-ha link 100 and through a lever .101 on a bracket 102 reciprocates a drill head 103 to cause 'the drill to advance and drill a hole at each one of the different positions marked. This drill head is operated from the shaft by means of a pulley 104 and belt.

It is also during this motion thatthetufts are set in a blankin the opposite position, namely, the position marked till. This has been described as operated from-the shaft 109 by cams.

Hopper fineclmm'sm.

The gear 51 is in mesh with agear 119 which drives a gear v120 loose on the cam shaft 121 lforcontrolling-the handle mechanism. On this shaft there is springpressed sliding member 122 adapted to be operatedbya lever ,f1-23 pivot-ed-oniafst-ud 124e and having -a pin 125 operated bya cam .12.6 on the shaft AThis pin 125 is'made adjustable-in a slot andsecured inadjust-ed-,position by a set screw 127. The other 'arm of the lever 123 is provided with a-stud-orroll and on the lever 123 isa spring-pressed pawl' 130 for entering said groove and stoppin-g the-clutch member and thereforetheshaft exactly at the end of the'revolution.

On this shaft y121 vis a lcam 131 'which controls a. roll 132on{a link 133. is bifurcated at its end to forni asupport and guide on the-shaft 121 and at the other end it is connected :with :a-lever 13.11 Vwhich ils pivoted at 1351to theend of :the frame -1. pivoted to the handle hopper 136. Gbviously the motion-of the-roller 132fout and in .with-relation tothe shaft 121. reciproeates the link 133.1and oscillatesthe lever 1134 so as to 'move 'the hopper :backandfforth vto brin-g it linto .registration with the ibrush handle turret fordelivery :thereto The hopper has an inclined back platz against which 'the blanks irest. It is :controlled by two angularendrplates 137, each held Ain position f by -adj ustable `brackets v138 supportedb the hopperitself. The brush blanks canv ble piled up lin ,the hopper `and fed down'by gravity. .'Ifidesired, a-weight` can be yapplied to Y'them to yinsure their iproper feeding, butitis notshownfh'ereinz-as it is not a necessaryv part 'offthe machine.

Also Inountetl'on this shaft 121 is1a l'feed and ejector cam 1410 operating .a rroll '141 on a lever 1421pivoted on the'shaft58. This lever is Vprovided with.' a flost motion connec-l tion with Aan adjustable :rod i143 lwhich in turn is pivoted to an adjustable member 144 carried by a lever 145 -pivoted-ontheback of the hopper`136. 'This lever is connected at its lower end'by a link 14-6 with a horizontal slide or plunger 114:7 having a .plate 148 for supporting, ,parallel .with it and spaced from it, a rigid pusher 149. The movement of the roll 141 out and in with relation tothe shaft 121 reciprocates the link 143, Witha lost "motion'atthe-end of the stroke, swingsthe lever M15-and reciprocates the lplunger and 4pusher so as .to

This flink Theother end of .this lever vabove is 'move the plunger along on a guide 189 at the bottom of the hopper136. Y

Mounted on the end of the plunger or slide 147 is a rod 150 having on the end thereof adjustable nuts 151 constituting a stop. @n the hopper is pivot-ed a. feed finger pawl 152 having' a projecting end 1.53 adapted to project in under the bottom of the hopper to support the end of the next to the lowest tooth brush blank or handle C. The lowest one is supported at ythis time by a plate 157 so as to project over the brush turret. A spring 154 normally holds this pawl up in the position shown in Fig. 29, the rod passing through a notch therein. `When the parts are in the position shown in Figs. 28 and 32 the stop 151 has forced this pawl over to the left to move the lowest blank to the left and hold the rest of the blanks in the hopper as indicated. Sis soon as the plunger moves to theA right far enough to allow the stop 151 to release the pawl 152 the latter moves over to the position shown in Fig. 29, being stopped by a flat surface 156 at the end of the pawl. This allows the pile'of brush blanks to drop down as indicated in this ligure when the plunger moves over. Tt will be understood that at the moment of feeding the whole hooper is moved over by the action of the cam 131 to registerv with the brush turret which will now be described.

The frame 41 `is provided with bearings these parts together with ycertain others to` be described, constitute the brush holding turret. Journalled in the hub 158 and the plate 159 are a plurality of parallel studs or shafts 160, six being shown in the present- ;tance. Extending out substantially radially from each of these and held against the plate 159 are the same number of stationary jaws 161. These. of course, rotate with the turret head and form a part thereof. Pivotally mounted on the shafts 160 are corresjionding movable jaws 162. Springs 168 nai-mally force the movable jaw inwardly r nst a sliding wedje 164 ".vhich located between each pair of These jaws are provided with inwardly extending projections 165 on the edge adapted to engage the brush blanks C and hold them in position.

For the purpose of operating the movable jawsfto permi" them to receiye and discharge the brush blanks the following mechanism is provided. The shaft 121 is provided with a wedge cam operating an arm 171 on a verticalshaft 172. This cam has a radial slot 169 to permit the end of the arm 171 to move through when-.the turret moves in one direction as has appeared. A spring 173 is provided for holding this this arm against the cam surface and the shaft has another army 17 4v at its upper end. This by means of a pin-and-slot connection operates a lever 175 pivoted on the frame 41 which reciprocates a rod 176 extending axially through the sleeve 11'() so as to engage and reciprocate a slide 178. This slide is provided with a pair of projections 179 operating the wedge 164. This wedge is provided with a plurality of slanting slots 180 engaging operating pins 181 `carried by the several stationary yjaws 161. As the wedge is pushed inwardly toward the wheel 116 by the projection 179 the wedge is raised between the jawsl so as to clamp the brush back under the projections 165. At the same time a wedge-shaped end 182 on the wedge 164 moves outwardly beyond the end of the movable jaw 162as shown in Fig. 20 and allows the spring to close that jaw. The wedge is forced out substantially into Contact with the wheel 116 at its end.

As the operation of depositing a brush j blank in the turret has been described in a general way, it is sufficient to saythat by the reciprocationk to the right of the plunger 147 the pusher 149 forces the lowest blank C in the hopper out of the hopper under the feed finger pawl 152, and the pusher moves the blank up against an adjustable stop screw 184 on thev wheel 116. The parts then move back into the position shown in Fig. 29; The pawl 152 allows another blank to drop down on the plate 157 anda-t the end of the reverse motion the end of the pawl 152 forces the lowest blank C intothe positionshown in Fig. 28. Before this has been accomplished. the projection 179 has been drawn back so that the wedge 182 forces the movable jaw to the right and opens it and the wedge 164 is lowered between the jaws. rThis leaves the jaws in proper position 'to receive the blank. Thereafter the wedge is moved in. the opposite direction to the position shown in full lines in Figs 2O and 21. The movable aw closes and the wedge rises so that the blank is clamped in theturret.

Ejector mechanism.

f will now describe the closely related mechanism for ejecting the brush blank from the turret. The position in which the blank is fed is indicated by the word Feel/l in Fig. l18 and the ejecting position by the word Eject inthat figure. AReferring now again to Fig. 22 it will be seen that the lever 142 operates a substantially vertical rod 1.90 adjustably connected with an arm lll 191A on ashaft 192'carried byaistationary ejector frame 193`y on the frame-41'. This shaft has another arm 1911l which" is connected bya-link 195' With an arm 196 on a shaft 19( which has aslotted arm-198 engaging." apin 199 Aon anejecting hook 200. rllh'is hook" is mounted'on awslide 201v Inovable in Ways onthe frame 193. rllhis ejector arm 20@ osci'lla'tes fromv theposition shown iirFig: 34 totliatI` shown in Fig. Where the" end of the'hook passes down" behind the end'ofthelrushblank ready tol draw it out of the turret on thev backwardlinovenient ofthe slide-201. It` Willbe noticed that'just' previously the Wedge 164 has justbeen operated to release the brush blank, tire-tivo positions of the WedgeV being lclearly indicated 'in Figs. gland 35.'-

Tlieslide 201 itself is operatedby'th'ese arms and links 194, 195, and'196'. The inotion ofthe arm 194 in the direction-of the arrow in Fig; 34 causes thfeslideto move back away from the stop 202 tothe left talkingwithl it, ofv course, the vhook and brush handle and ejectingthesame into a hopper or 'other receiving means as desired. fr stop 203 is provided for limiting the downward motion of the ejector'hoo'k.

Operation.

rll`he*operationl of the machine is as fol-I lows: The-'transferring means takes theV cup and Idelivers it4` to the'fm'echanisrn fonappl'ying the bristle-filled cups to the brush blank The transferringfdevice' swings up into position to engage ythe bristles and prevent the tufti fallingavvay Aand attlie same time hold it' on the transferring device. The details of the operationof this transferrer having been described in connection With the original patent this operation will not be repeatedhere, but itV is suicient to say that the transferrer, having grasped the tuft beyond its metallic cap, swings over through a considerable arc into asubstantially horizontal position from which the t-uft is applied to the brush handle'or blank under pressure and left secured therein by friction.

The operation on the brush blank is as follows: These blanks, having been previously formedtothe proper length and other outside dimensions, are placed in the brush blank hopper. Duringl each complete operation of this machine this hopper is reciprocated and the lower blank discharged therefrom on one of the faces of the brush blank'turret. The blank'is left o'nthe turret in the proper position and onefof the spring gripping jaws thereon engages the blank and holds it in its proper relative position to the turret. The wedge also moves to receive `it in place. The turret is then indexed around one step which brings another Iface into position to receive another cams which controlthe tivo ymotions ofthe The brush blank having passed 1 turret. through all these motions and the desired number of holes `having been drilled, the yturretv` indexes around again through tWoidle positions While two other blanksa-rebeing drilled and'tlien comes up tothe fifthposition in which it is directly oppositethe drilling position and-at that time the tufts are supplied from the transferring devices in proper order and insertedin the holes in the blank in thev same order in which the holes'arebeingdrilled in a fresh blank oppositely located. rlhe operationof'the turretA to bring it to the drilling positions' also serves to bring this blank to the proper positions for tufting. rlhe tufts having been applied and forced into the holes bythe mechanism which has been described, the turret is again indexed around tothe sixth position Where the ejector engages the new complete'dbrush and forces it longitudinally out ofthe spring clamp, Which'has held it, into a hopper, conveyor or any other receiving means (not shown).

Itvvill beseen therefore thatthis machine is entirely automatic, taking the tufts of bristles and previously formed brush blanks at different points, drillingthe holes in the blanks, and forcingthe tuftsinto the' holes thus formed so as to produce the completeI brush which needs only to have the bristles trimmed down to the proper leng'tlrafter it leaves the machine'. All the parts are con'- veyed froinone position to another in the machine automatically and there is no need for any expert oversight ofthe' operations. Practically all'that the operator has to do is to see that the machine is running, and to see that it is properly supplied with the three kinds ofraw products Whiclritus f' rl`he strictly metal Worllzing mechanism by itself and the tuft` forming and setting mechanism'by itself are not claimed herein independently of other features of themachine as they forni the subject matter of tvco divisional applications previously tiled.

Although l have illustrated anddescribed only a single embodiment of the inventioi'i' and shown it as applied to a definite character of brush l ain aware ofthe fact that many modifications can be made in the de- The last row oft-Wo ill? y1,627,7av

tails of construction and combinations of parts of the mechanism and that it can be applied to the manufacture of other types of brushes without departing from the scope of the invention as expressed in the claims.

Therefore I do not wish to be limited in these respects, but what I do claim is l. In a brush making machine, the conibination of a brush turret for supporting brush blanks, means for moving said turret up and' down, means for moving the turret longitudinally, and means for intermittently rotating the turret, with means for drilling a hole in the brush blank on one side ofthe turret in each position, and means for setting a tuft of bristles in the brush blank when in a diametrically opposite position.

2.
