BRUSH MACHINE,

Application filed May 25,

To all trimm t 0n ty concern-f Be it known that l, WALTER C. Fnsi), a citizen of the United States, residing in the town of Bloomfield, county of Essex, and State of New Jersey, have invented certain new and useful improvements in Brush Machines7 of which the following is a speciiication.

My invention relates to a device designed to hold a wooden blank which is to become the back of a brush, and iirmly to position this blank while it is undergoing certain operations in the course of brush manufacture. such as drilling the blank with the holes which are to receive the tufts and subsequently tufting the brush, that is, inserting` the tufts or bristles in the previously drilled holes and securing them in place.

My invention aims to perform the various functions attendant upon positioning and holding the blank in predetermined successive positions without manual effort or attention on the part of the operator, all the various operations being accomplished automatically by suitable mechanism. vWhile thus doing away with hand labor and thus reducing the cost ol manufacture, my invention also makes possible the further vance of absolute uniformity in the product, thatA is7 every back will be drilled with the saine number of holes, positioned exactly the same and of uniform depth, so that if a drilling machine and tufting machine are coupled together, the blanks after being drilled may be removed from the holder or carrier ofthe drilling machine and placed in a similar carrier of the tufting machine with the definite certainty that the tufts will centrally enter the holes previously drilled. lvlany other advantages will become apparent from the following specification.

ln the accompanying drawings. which form a part of this specification7 Figure 1 is a front elevation of one embodiment of my invention mounted in connection with a drilling machine of the usual type. Figure 2 is a fragmentary view, also in front elevation, of the blank carriers and part of their operating mechanism at the phase in the operation of the machine when the drill has finished operating on one blank and is about to drill a companion blank. Figure 3 is a top view on an enlarged scale of the carrier mechanism in the position of Figure 1. Fig- 'lV-V of Figure 3.

- Referring to the drawings in detail, the numeral 1 designates a base upon which is mounted a frame 2, in which is journaled a shaft 3 upon which is loosely mounted a nulley et driven by belt 5. The clutch 6 splined to the shaft 3 is adapted to lock the pulley on the shaft and cause the simultaneous rotation thereof. Upon the shaft 3 is mounted a gear 7 meshing` with gear 8 on the shaft 9, likewise mounted in the frame 2 and carrying upon its inner end the cams 10 and 11. The cam 11 is provided with a. follower 12 (see Figures 5 and 10) mounted upon an arm 13 pivoted at 14 to a fixed part of the framework of the machine and pivotally connected at an intermediate point to an arm 15, which is pivoted at 16 to a bell crank lever 1T. Upon the extending end 1S of this bell crank lever is pivoted a pawl 19, which is constantly urged toward the lever by means of a spring 20. This pawl is adapted to engage teeth 2l on the periphery of `a wheel 22 fixed to the shaft 23, which is suitably mounted in bearings 25. flach revolution of the cam 11 in the direction of the arrow in Figure causes the pawl 19 to advance the wheel 22 a step equal 'to the length of a tooth and a space between two teeth and then returns the pawl to its initial posit-ion,

where it will enter the space between the next two teeth. lt will be seen that the shape of the pawl is such that in moving downward in Figure 10, it will be locked with the teeth of the wheel 22 and will cause the wheel to move with it, while in moving upward the pawl will ride over the teeth. rlfhe cams 10 and 1l are so designed and bear V such an angular relationship to each other that at the instant the pawl 19 ends its downward travel, that is, when it has advanced the wheel 22 a complete step, the wheel will be locked in that position by means of a dog 2G carried by a block 27, which has a pin-and-slot connection with a lever 28 pivoted to the frame at 29 and having its upper end pivoted to a link 30, which in turn is pivoted t0 an arm 81 mounted upon a rock shaft'32 to which is also secured the arm carrying the follower 311 of the cam 10. lt will thus be seen that by the mechanism thus far described the continuous revolution of the shaft 3 gives the wheel 22 and the shaft 23 a step-by-step movement equal to the length of a tooth and the distance between two teeth.

Mounted in guideways 35 in front of the machine is a vertically sliding arm 36 in which is journaled a chuck 37 of any suitable construction for holding the drill 38. The upper end of the shaft to which the chuck is secured is provided with a pulley 39 over which passes a belt el() running over the guide pulleys al and pulley l2 on shaft e3. This shaft carries another pulley all, which is continuously driven by the belt l5 passing over a pulley @t6 on the shaft 3. By this mechanism the drill 38 is continuously rotated 'as long as the shaft 3 revolves. The arm 36 and consequently the drill are reciprocated vertically@ by mechanism includ-` ing an arm 4T pivoted to the arm 36 at i8 and at its other end to a bell-crank lever 4:9 centrally mounted upon the frame of the machine. The other end of this bellcrank lever is pivoted' at 50 to the connecting rod.

inseam consist of a body portion 5?, and a handle 54. rlhe face of the body portion is customarily curved transversely, shown in Figure l?, and the tip 55 is curved or beveled ofi shown in Figure 13.

ln the manufacture of a brush of this type, the tufts are usually placed radially with respect to the transverse curvature and while they are perpendicular to the axis of the brush near the handle, as shown in Figures 13 and 16, they" are inclined at an increasing angle as the tip is reached. Furthermore, in order to n'iake the bristles appear uniform, it is necessary to have the tufts closer together at the tip, where they are inclined sharply away from each other, than near the handle where they are more or less parallel. lt will thus be seen that a complex motion of the blank holder or carrier is necessary, if the drill is toV have a simple vertical reciprocating movement. Not only must theholder be capable of a transverse tilting movement about the center of curvature of the face of the blank, but it must also be tilt-able longitudinally to accomplish the inclining of the tufts required by the mutual inclination of the holes in Figure 16and must also be capable of a movement toward and away from the drill, since the holes are bored to a substantially uniform depth. The carrier must also move back and forth so as to coverl the area of the body of the blank with the desired number of holes, and their spacing must be constant and predetermined. The carrier and the mechanism for giving it these complex movements will now be described.

The blank holders consist of

plates

56 and 57 mounted upon. the

frames

58 and 59, respectively, (see Figures 3, 4 and 7). Each plate is provided at one side with a stop or guide 60, against which one side of the blank isadapted to be seated, and at one end with stops 6l having beveled faces adapted to engage the narrowing part of the blank. il movable clip 62 forced inwardly by means of springs 63, is adapted to be clamped against the other side of the blank by the wing bolt 6e. It will be understood that in placing a blank in the machine, the wing bolt 64 is retracted suiiiciently to permit the blank to be placed by the operator in Contact with the stops 60 and 6l. A turn of the wing boltv 64 will then be sufficient to clamp the blank between the clip 62 and the stops, its longitudinal position being determined by the engagement of the stops 61 with the receding ends of the blank adjacent to the handle. lt will be seen that the plates and the frames to which they are secured are angularly disposed with reference to each other and that the stops are so arranged that the carrier is capable of holding two blanks with the tips' close together. Each llO of the

frames

58 and 59 is provided with y depending ends having the lower edges 66 formed on an arc and seating upon similarly curved surfaces 67 in a sub-trame 68. The

surfaces

66 and 67 are held in continuous but slidable engagement by means ot pins 69 mounted upon supports 70 secured to the sub-frame and entering grooves 71 in the members 65, these grooves being` formed about the same axis as the

surfaces

66 and 67. By this construction, the carriers and the blanks are capable oi transverse tilting movement about the axis ot the curved surfaces 66. lThe machine is so designed that this axis is also the axis of the transverse curvature ot the blank when it is in position in the carrier. The device for communicating tilting motion to the carriers includes pins 72 projecting from blocks slidably mounted in the adjacent end members 65 ot the two carriers and enteringholes in a spool 78 mounted upon rod 74C. This rod is adapted to reciprocate freely in bearings formed in an upward extension of the sub-frame and is secured at its inner end to an arm 75 mounted in and connecting

uprights

76 and 77, the lower ends having a dove-tail connection at 7 6 and79, respectively, with a fixed portion of the main frame of the machine. This construction provides a frame which is adapted to slide horizontally in a direction forwardly and rearwardly of the machine. The position of this trame and consequently the transverse tilting motion of the carrier are controlled by a cam 80 on one face of the wheel 22. This cam is provided with a follower 81 mounted on and arm 82 secured at its other end to a shaft 83, which is provided with arms 81 and 85 pivoted to

links

86 and 87, respectively, which are in turn pivoted to the

uprights

76 and 77. lt will be seen that the cam groove 80 causes the oscillation of the arm 82 and through its linkage produces a reciprocation or the

menibers

76 and 77 connected by the arm 75 which in turn reciprocates the rod 74 and thus tilts the carriers transversely.

The sub-frame 68 has the general form or" a cross, the top carrying the rod k711 and the arms supporting the outer ends oit the carriers. This cross is provided centrally with a transverse shaft 90 extending laterally beyond the sub-frame on each side and providedl with the

rollers

91 and 92 resting on the

arcuate rails

93 and 94. respectively. T he position of the sub-frame, and consequently of the carriers and the blanks is determined by the following mechanism:

Link 95 is pivoted at 96 to an arm 97 secured to the upper part of one side oit the sub-trame. rilhe other end of this link is pivoted at 98 to one arm 99 oi' a bell-crank lever, which is pivoted to the frame at 100. The other arm 101 oi' this lever is pivoted to the upper end of the link 102, the bottom ot which is pivotcd to an arm 103. The link may be provided with the turn-buckle Yfor purposes oi adjustment. The inner end of the lever 103 is pivotedly mounted upon the shaft 105. Centrally mounted upon the lever 10T-l is a "'lshalied dog 106, Ywhich is tree 'to more about the point 107 as an i il" xure 6). lilith the parts in the position shown in Figure 6, the extending cnil o1 this is thrown to the right into a slot 108 in one arm 109 ot a bell-crank'leve mounted upon the shaft 105 Figure 11). The other arm 110 of this lever is provided with a cani roller or follower 111 entering a cam groove 112 in the Vface et' the wheel 52 opposite to the cam 60. V11s the wheel 22 revolves, it will cause an oscillation of the hell-crank arm 110, and when the dog 106 is in the position shown in Figure 6, the other aim 109 and the lever 109 are locked together by the dog, and consequently this oscillation ot the arm 109 will be communicated to the arm 95 through the linkage previously described, and this will control the position ot the arm 97 and thereby the upper end of the cross forming the sub-traine for the carriers. `When, however, 'the dog 106 is thrown to the lei't with relation to Figure 6, direct connection between the bell-crank arm 109 arl the er er will be broken. The dog wi "hen enter a slot in a lever 113, which is freely mounted upon the shaft 105 and which has its end connected by a link 11eL to a bell-crank lever 115 pivoted to the frame at 116. rEhe upper end of this bell-eranlnlere is pivoted at 117 to a link Q, w iieh pivoted at 119 to the arm 110. llfhr such connection is established between the arn 103 and the lever 113, any movemen it the bell-crank arm 110 toward *lie rear o the machine, instead of lifting4 the arm 103 villrlepress it, since the connection between the hell-crank arm 109 and the arm 10S has been broken and motion is now communicated from the arm 110 to the arm 10B through li 1, bell-crank lever 115,

iik rie link 1Y et, rever 1123 and dog 106. This mechanism thus affords an eri-festive means `for causi a reverse movement ot the arm 103' with re'l'erence to the motion of the bell-crank arm 110 merely by shitting the dog' 106 through small angle.

ne mechanism which controls the action log consists or". a :trame including the 120, which span the 'shaped head K6, aid the horizontal connect- '

t

21, 122, the entire trarne being laterally in the main trame oi the machine. The position oi' the frame is controlled by a lever 123 pivoted to the main at and having its lower end connected to 'the member 121 by a pin-and-slo't connection 125 (see Figure 1) The upper end ot the lever 123 is provided with a wide notch 126, adjacent to which is pivoted a latch 127 (see 11 igure 2li). Projecting rearvxardly 'from the latch is a pin 128 adapted to move in the notch r1`he upper end of the latch is connected to the lever 123 by a spring1 12S. lt will be seen that the latch has two positions oi rest, one in which the pin 123 is in contact `with tue right-hand side ot the notch 126 as shown in Figures 1 and 211, and another in Which the latch is svi/ung to the lett with the pin bearing LLinst the lett-hand side of the notch as in Figure Once in every revolution o1' the wheel ioo mounted upon the shaft 23 the latch is engaged by a pin 131. lt `the parts are in the position shown in ligures 1 and 241, the pin 131 vrill strike the upper portion of 'the latch and Will swing; the upper end oi the lever 123 tothe right. rliis Will throw the lower end ot the lever 123 and consecpaentlg7 the/trame to which it is connectcd to the loft with reference to Figure 1 and Will shift the dog 106 into the position oli Figure 6. Further travel ot the pin 131 will cause it to encounter the lower curved portion oiI the latch 127, and will throw the latch into its other position, namely, With the pin 128 restingagainst the lett-hand end ot the notch 126, but this is accomplished Without any further movement of the lever 123. This is the position shown in.

lfig'ure rthe nent revolution oi the Wheel will bring the pin 131 against the other face oi the latch, first swinging the upper end ol the lever 123 to the left, .vith respect to Figures 1 and 24, and then moving the latch about its pivot into the position shown in. these iigures. t each complete revohition of the Wheel 130 .vhen the pin 131 strikes the latch, there Will be amovcment of the trame to which the lever 123 is connected, either to the riadit or to the leit, as the case may' he, and consequently a reversal of the motion or' the arm 103 with reference to the bell-crank arm 110 and therefore with reference to the cani 112 and its `l'ollovver 111.

'lhe lower end ol the arm o the cross which forms the sub-trame 'tor the carriers is pivoted at 132 to a link 133, the other end of which is pivoted to a bell-crank lever 131 having; its opposite arm pivoted to a link 135 connected at its lower end to an arm 136 loo, ly mounted upon the shaiit 1053, which carries a dos` 137 adapted to engage either the lever 133 or the arm 139 ot a bell-crank lever 140 provided at its upper end \.v ith a roller or cam follower 111 entering;` a cam groove 141-2 in one 'lace of the Wheel 139.

The inechanism tor operatingthe dool 137 consists ot uprights -113 termini;l a part ot the same Ytrame as the uprights 120 and moving; with them. so that a similar and synchronous reversa-l ot motion is aiiiorded. The lever 133 is connected by suitable linkage including a bell-crank lever 1411 (see bell-crank lever 168.

Figure 8) to the upper arm of the bell-crank lever 1410, this back gearing` being the same as in the case oi the mechanism actuated by the cam 112, and providing the saine reversing action.

'l'he rails 93 and 941 are connected by a bar 150 (see Figure and each is mounted upon a lf-shaped trame pivoted at 151 to a cross-head 152 provided With slots 153 in which are mounted bolts 1511V secured to the 'main trame ol the machine. This cross head is Vvertically adjustable by means of a screvv 1:55 passing through the internally threaded block 156 mounted upon the main frame and provided with a hand Wheel 157. The crosshead is also provided with an upwardly extending arm 158 (see Figure 1) which is con ected by the pivotally mounted

links

159, 160 to the rod 90 forming` the axis oi the

rollers

91 and 92.

'lhe position ot the rails and their supportingl 'trame with reference to the axis o' theirpivotal mounting` 151 is controlled by mechanism precisely similar to that connected to the lower end of the cross forming` the sub-trame. rlfhis consists of a link 161 pivoted to the rail 911 at 162 and at its other end to a bell-crank lever 163, the lower end oit which is connected by the link 1611 to an arm carrying the dog` 166, similar in its construction and 'functions to the

dogs

196 and 137. This dog is adapted to cooperate either with one end oi the bell-crank lever 167 mounted on shalt 105a or with the lever 1which is connected lby the link 169 to the bell-crank lever 170 pivoted to the main `iframe at 171 (see Figures 6, 8 and 9). The upper arm ot this lever is connected by a link 172 to the upwardly extending arm 173 ot' The arm 173 carries at its upper end a roller 171i which enters and terms the follower oit theV cam groove 175 on the tace oi the Wheel 130 opposite trom the cam 1112. The position ot the dog 166 is controlled by uprights 176 which are secured to the

uprights

120 and 143 by th connecting`

members

121, 122.

ln the operation of the device, assuming` that the pulley d is continuously rotated by the belt 5 and the clutch 6 is engaged, the drill'Will be rotated continuously by belts l() anc. e5 and pulleys and shafts -with which they cooperate. llach time the cani 11 makes one complete rotation, the drill Will be given a complete vertical reciprocation through the bell-crank levers and links which connect them, since the cams 19 and 11 are mounted on the same shatt and revolve with it. For each reciprocation et the drill, the

wheels

22 and 130` will be advanced one step through the action of the mechanism actuated by cams 1() and 11 and this interval Will consist of al relatively short period during which the Wheels are being advanced one step by the paivl 19 and a relatively long period during which they are locked in stationary position by the dog 26. The relation of the cams to the point 52 at which the arm 51 is pivoted to the cani 11 is such that it will be during this period of rest that the drill makes its downward travel or operative stroke. Consequently, when the drill is making its downward stroke, the carriers and the blanks held by them are stationary. rlhe step-by-step movement of

thewiieels

22 and 130 results in a variety of motions being imparted to the carriers through the agency of the four

cams

80, 112, 1112 and 175 and the mechanism which connects them to the carriers. The cam 80 acting through the arm 82 controls the posit-ion of the rod 7/1- in the manner already described and thus causes the transverse tilting of the carriers, oscillating the blanks about the center of the curvature of the faces which are being drilled. The cam 112 acting either directly through the bell-crank lever 110 or indirectly through the back gearing including the bell-crank lever 115, moves the arm 103, which in turn imparts motion to the link 95, which controls the position of the upper part of the cross forming part of the sub-frame of the carrier. Coincidently the position of the lower end of this cross is controlled by the link 133 actuated either directly or indirectly through its back gearing by the cam 142. l/Vith the top and bottom of the cross thus controlled, the

rollers

91 and 92 are free to move along the rails 93 and 9leXcept as their motion may be limited by the

links

159 and 160 pivoted to the arm 158 of the cross head 152.

Simultaneously, however, the positions of the rails and consequently 'the vertical elevation of the center of the cross is controlled by the cam 175 acting through its linkage.

,The compound motion of the carriers may be briefly described as consisting of a transverse tilting and a tilting about an aXis through the center of the cross accomplished by the links 95 and 133 (which may also produce a movement of the rollers along vthe rails) and finally a movement of the rails themselves.

In the position of the parts in Figures 1, 5, 7, 8, 10 and 12, the machine is shown operating upon the first row of the right-hand blank. Referring to Figure 12, it will be seen that the machine has finished operating on the blank 180, the last hole having been drilled at 181. The carriers were then moved by an operation which will later be described, into the position for drilling hole 182, and then the other holes drilled in order, the machine being in the act of drilling 183 at the phase shown 'in these figures. Upon the completion of the first row with hole 184;, the blank is tilted to drill 185 and 186 and then the next two rows, of which these form the end holes, are drilled, the order of drilling being indicated by dotted lines in Figure 14:. From hole 187 the operation is continued and completed in a direct line to finish the fourth row, as shown in Figure 14, this row ending with hole 188, after which hole 189 (see Figure 15) and the last row is drilled ending with hole 190. The carrier then moves the blank into position to drill hole 191. it is to be noted that because the last hole drilled in the blank is actually the first hole of the fourth row, this brings the machine into proper position to jump a minimum distance from the blank 53 to the new blank 192 (see Figure 18), with which the attendant has replaced the blank 1,80 at the completion of the latter. By having the machine complete drilling the blank 53 with the hole 191 instead of the hole 190, only a comparatively short jump is necessary to the next hole 193 in the new blank. This jump is accomplished at the phase of the machine shown in Figure 11, with the point 194: of the cam 112 acting' to move the carrier the required distance. Figure 2 shows the parts in the neutral position just as the shift is being made from one blank to the other. Figure 9 corresponds to Figure 11 and shows that the tooth 131 is just engaging the latch 137 so as to swing the upper end of the arm 123 into the left-hand position, thereby shifting the frame including the uprights 120, 1113 and 17 6 to the right. This will reverse the various motions which have previously been imparted to the carriers by the three cams 112, 1&12 and 175 through the shifting of the engagement of the

dogs

105, 137 and 166 with the various members of their actuating mechanism. Consequently, whereasthe carrier has been turning in Figure 18 in such a direction as to bore the

holes

190 and 191 consecutively, it will continue its motion in the same direction and will bore

holes

193, 195 and 196 in the blank in spite of the fact that the cam 112, immediately recedes toward the center of the wheel 22 after the high point 1941 is passed. This reversal of action at the critical instantof passing from one blank to the other makes it possible to use cams only half as long as would otherwise be necessary, since the movement of the follower 111 rearwardly (toward the axis of the shaft 23) as the wheel 22 continues to revolve produces the same effect upon the motion of the arm 103 by virtue of the reversing mechanism as though the cam 112 continued to increase its radiusthat is its distance away from the aXis of the shaft 23 after the critical point 19e was passed. The same thing is true of the

other cams

142 and 175 and their associated mechanism. Consequently, the holes of blank 180 are bored in a sequence reversed from that of the blank 53. ln other words, the line of which the hole 196 is the first, is completed and then the next two lines are drilled by a zigzag motion, as shown in Figure 20, until the hole 197 is reached, from which the machine jumps to the hole 198, completes that row (except tor the iinal hole 199 indicated in dotted lines, which corresponds to the hole 191). The last row, be-

niug with the hole 200, is drilled in a straight line until the hole 201 is reached from which point the machine goes into position to drill hole 199. Before this time, the operator has replaced the blank 53, Which has been completed, with a fresh blank and at the instant the hole 199 is bored, the machine comes back to the position shown in Fir/rufe l1; that is, with the critical point 19a of the cam 112 acting to throw the carriers a suilicient distance to swing them to the hole 209 about to be bored in the new'blank 203 (see Figure 20). Then, the pin 131 actuates the reversing mechanism and as the hole 202 is bored, reverses the machine into the position in which it initially was, thus completing a lull cycle of operations. The dotted lines in Figure l show the corresponding position for drilling the left-hand blank.

ll/Yhile l lhave illustrated my invention as applied to a machine tor boring or drilling` holes in brush backs, it will be obvious that it may be applied to other uses, as tor instance, by replacing the drill with anyy desired form oi' tufting mechanism for inserting the tuiits or bristles into holes previously bored, and a matter of tact in practice, l have 'found it feasible to use such drilling and tutting mechanism interchangeably or there may be a plurality of sets oi carriers precisely similar in all respects and all actuated from a single set of cams merely by connecting their various pivot'points to each other with links, so that when any point, 'for instance 132, ot one carrier is moved, all Will move simultaneously. lllhere such sets of carriers are provided, the blank which has just been drilled in one carrier may be removed and placed in a corresponding carrier ot' an adjacent set, which is operated upon by a tutting machine instead. of a drill, and the brush automatically tufted by that machine.

lllhile l have illustrated and described l only one spccilic embodiment o1" my invention, l realize that it is susceptible of Wide adaptation, and l do not desire to be limited to the precise mechanism shown and descril ed.
