Patented Sept. 21, 1909.

Application filed October 12, 1907. Serial No. 397,040.

To all whom it ma/y concern:

Be it known that I, GILroRD S. MURDooK,

and State of Michigan, having invented certain new and useful Improvements in Brush- Making Machines, of which the following is a specification, reference being had therein I to the accompanying drawings.

This invention relates to improvements in I brush making machines of that class in which the fibrous material is automatically fed in bunches to stapling mechanism which also embodies means for making and driving the staples; and the objectof the invention is to provide a feeding mechanism which will gather from a suitable hopper a bunch of material of the desired size, and firmly hold the fibers straight and even as it feeds the bunch to the stapling mechanism.

A further object is to provide a hopper so constructed and arranged that the fibrous material is firmly held straight and even therein and fed to the delivery slide in such a manner as to insure the delivery of a full even bunch each time, and also to provide a machine embodying certain other new and useful features in its construction, combination and arrangement of parts, all as hereinafter more fully described reference being had to the accompanying drawing, in which Figure 1 is a plan view of a device embodying the invention, with parts broken away to show the construction; Fig. 2 a vertical section of the same substantially on the line .r:u of Fig. 1; Fig. 3 is an enlarged detail showing a front. elevation of the hopper, stapling, and feeding mechanisms; Figs. 4 and 5 are similar details showing the operation of the bunch releasing lever; Fig. 6

is an enlarged detail showing the closing g plate of the feed slide and the adjustable stop therefor with the adjacent parts of the machine: Fig. 7 is an enlarged detail showing the hopperin end elevation with its presser, foot and mechanism for operating the same; Fig. 8 is a longitudinal section of the hopper on the line g y of Fig. 7 Fig. 9 is a perspective view of one of the adjustable hopper partitions detached; Fig. 10 is a. perspective view of the feed slide and its supporting guide;

Fig. 11 is an enlarged perspective view of the slide detached and showing its side opposite to that shown in a citizen of the United States of America, i Fig. 10.

residing-at Detroit, in the county of lVayne j mounted at its rear edge a shaft 2 provided at one end with a driving pulley 3 which is 1 is a suitable bed or table upon which is loose on the shaft and is attached thereto to turn the same, by a suitable clutch 4.

5 is a bracket secured to the table 1 at its forward edge and provided with vertical guide ways for the reciprocating slide or head 6 which is actuated by a rocking lever 7 pivoted intermediate its ends with its forward end projecting between friction rolls 8 on the slide and its rear end engaging a cam wheel 9 on the shaft 2 for actuating the slide in both directions.

10 is a vertically movable die block traveling 1n guides 11 secured to the table directly below the slide 6 and 12 in a lever engaging said block to operate the same, which lever is pivoted intermediate its ends and at its rear end engages a slotted or grooved cam 13 on the shaft 2 for operating said lever in timed relation to the movement of the slide 6 which slide has secured thereto a needle 14 working vertically through the die block in a suitable passage provided therefor having grooves to receive the ribs 15 on the needle. said grooved passage forms a die to receive a wire which 1s formed, upon the downward movement of the block, over the end of a finger bar 16, into a staple. This finger is projected into the path of the die and retracted therefrom in timed relation to the movement of the other parts by being piv otally attached at its rear end to a rocker 17 pivoted intermediate its ends on the table and attached at its opposite end to the forward end of a reciprocating rod 18 which is moved by an internal slotted or grooved cam 19 on the shaft 2. Carried by the die block is a suitable knife 20 for severing the wire in proper lengths for the staples and the wire is fed in by'suitable levers 21 pivoted on the table and actuated by a cam 22 on the shaft 2, the forward end of the forward lever being provided with a suitable gripping device 23 to engage the wire and a similar gripper 24 being provided to prevent the retrograde movement of the wire.

All of the foregoing described parts are cross-section of the same; and Fig. 12 is a 5 arranged and constructed to operate $1110- The lower end of stantially as shown and described in my application for Letters Patent filed in the linited States Patent Ofiice on 2nd day of August 1907, Serial No. 386.722.

it long feed hopper for holding bristles or fibrous material, is secured in an inclined position to the supporting frame or table of the machine, with its lower or discharge end adjacentto the guide bracket 5. The upper side of this hopper at its lower end is open and through this opening 26 is fed the material which is placed in the hop- 5 per through an opening in its upper side the discharge opening.

and at' theirrear ends are provided with shoulders 29 to engage notches in the end of the hopper and at their forward ends, are formed with downwardly extending shoulders 30 at the lower edges to engage a extending ears on the hopper and hangs downward through a slot therein to engage the lug and when the slide is drawn out. the latch will swing, permitting the lug to pass, but. when the slide moves inward the end of the latch engages said lug and being prevented from swinging in the opposite direction by engagement with the end of its slot, it prevents the inward movement of the slide until turned out of the path of the lug by the operator. j

The lower end of the hopper is rounded at its lower side so that it will take up less space adjacent to the stapling mechanism and also guide the material upward toward is left open and provided with strips or lingers 43 extending across the open end and secured at their upper ends to the hopper at: the upper edge of the open end (see Fig. 7) to prevent. the material from escaping, and between these strips is a presser foot.v 44 of any suitable form which engages the lower side of the bunch of material and presses bar 31 extending across the lower side of the i hopper, which bar is strongly pressed and held in engagement with the shoulders by springs so that each partition is forced longitudinally by the springs to yieldingly hold its shoulders 29 in engagement with their notches. Adjusting screws 33 side of the hopper near its lower end into engagement with the partitions and thus said partitions are firmly held in place, and at the same time may be quickly and easily adjusted toward or from each other to accommodate the'ditl'erent lengths of material,

by turning the screws in or out and against I the action of the springs 32, disengagmg the extend inward through each1 shoulders at the upper ends of the partitions T from their notches in the casing and moving them in or out into engagement with other notches. The partitions are also provided with flanges i-B-l within the discharge opening 26 of the hopper, which flanges extend over the ends of the material a short disof the lever 47 between its pivot and its hopper. said slide being actuated by weights cud ot' the slide by cables running over pulleys on the sides of the hopper. Friction rolls 39 in the bottom ol' the hopper casing engaging the slide,- insure l'rce movemcnt thereof, and on the inner end of said slide is a .lug ltl to engage a stop pm 41 in the top ot' the casing and prevent the slide from being pulled entirely out when lifted to till the hopper. a gravity latch l2 being also provided adjacent .to the stop pin to l|old the slide while the hopper-is being tilled. This latch is pivoted upon upwardly l l l l the same upward toward the discharge opening. This foot is carried by a lever 45 extending beneath the table 1 and pivoted intermediate its ends between ears 4.6 on a second lever 47 which is provided with a friction roll .at one end engaging a cam 48 on the shaft 2 and at its opposite end with a coiled spring 49 interposed between it, and the lever 45. The second lever is pivoted intermediate its ends between ears 50 on a supporting bracket which is secured to any convenient part of the machine-frame beneath the table and which is formed with laterally extending arms one of which is provided with a guide lug 51 for the roll end of the lever 47 and the other arm with an adjustable stop screw 52 to engage the lower edge of said lever near the end thereof carrying the spring 49. An adjusting screw 53 is provided for said spring to regulate its tension and the lever 45 is adjusted relative to the lever +7 by a set screw 54 passing therethrough and engaging the upper edge rear end carrying the cam roll. The lever l7 when turned on its ear pivot 50 is guided in; its movement by the lug 51 on the fixed braclt'et-arm and is limited in its turning in one direction by the stop-screw 52 on the ing to actuate the presser foot in timedrelation to the movement of, the mechanism which feeds the material in bunches to the stapling mechanism and the spring-l9 yieldmgly pressing the foot into contact with the This rounded end material, thus putting an even pressure thereon regardless of the varying density of the bunch of material in the hopper.

Suspended over the hopper in the central vcrtial plane thereof, by bracket arms secured to the table. is a guide 56 for the feed slide 57 which slide consists of two relatively movable members or plates 58 and 59, the member 58 being formed with laterally extending flanges 60 at its upper edge which are adapted to slide within the grooves formed in the inner edges of the side bars (31 of the guide. Bolts or pins 62 are secured to these bars and pass loosely through openings in the top plate 63, and on these pins between their heads and the said top plate are sleeved coiled springs which exert a force to draw the bars toward said plate and frictionally clamp the flanges of the slide between. The member or plate of the slide is formed. with an extended portion or finger til at one end having a deep notch or cut (35 in its lower edge at a distance from its end, extending inward toward said end at an angle, a corresponding plate 99 having a finger 100 is secured thereto to form a hook to engage the material in the opening in the hopper and to form a pocket to receive the desired size of bunch, the size or depth of said notch or pocket being determined by a slide (36 adjustably secured to the finger and having a tongue projecting into said notch. The closing plate 5!) is attached to one side of the member 58 by tap screws 07 extending through slotted openings 8 and (it) in said plate, the forward opening (3t) being formed with a notch at one end so that the forward end of said plate is free to rise when the plate is moved relatively to the member 58 with said screws in the forward ends of their slots. \Vhen the plate is moved forward relative to the member 58, its forward end lies beyond the point of the hook, thus closing the opening into the slot and firmly holding the bunch of material therein, and said end is also cut at an angle and provided with a groove 71 so that. when the feed slide is at the forward end of its stroke, said end forms one side of a guide for the staple which in the operation of the machine has just been formed over the finger, the opposite side of the guide being formed by the grooved end of an adjustable plate 72.

To cause the closing plate 59 tostop in its forward movement in exactly the desired position to receive and guide the staple, a stop plate 73 is secured to one side of the bracket forming the ways for the die block. and within a suitable undercut groove in the side of said bracket is a tapered wedge 74 having an inclined edge to engage the undercut side of the groove. -An ear 7?) is provided on the outer end of the wedge and a screw It; having a head to engage the can passes through a slot in said ear and engages a screwthreaded opening in the bracket. A shoul der 77 on the closing plate engages the stop plate when the feed slide is in its forward position and by turning the screw 76 the wedge is forced beneath the stop plate to adjust the same, so that it will stop the closing plate at the desired point.

To reciprocate the feed slide, a lever 78 is pivoted at one end on the machine table and its opposite or forward end fits into and pro jects through an opening 79 in the closing plate 59 and on through a slot 80 in the finger plate 58. A rocker bar 81, pivoted inter mediate its ends on the table, is provided with a roll at its rear end to engage a cam slot in a-cam wheel 82 on the cam shaft 2 and at its forward end is connected by a link 83 to the lever 78. baid link is provided with a joint 84: to permit of annular movementof the lever and with a socket member 85 having an internally screw-threaded bore to receive a screw-threaded eye bolt 86, the socket member being detachably pivoted toan eye bolt 87 on the end of the rocker bar, so that it may be detached from said bar and turned on its eye bolt to adjust the length of the link and thus change the throw of the lever. A further adjustment is secured by providing a clamping socket 88 on the end of the rocker bar to receive a sleeve in which the end of the eye bolt 87 is free to turn, said sleeve may be moved in or out of said socket by loosening the clamping screw and the length of the rocker thus changed. \V hen the feed slide is at the rear end of its movement, the first forward movement of the lever 78 moves the closing plate 59 without moving the finger plate 58, said finger plate being frictionally held by theclamping guide 56 and the elongated slot 80 in said plate providing such movement before the lever engages the end of the slot to move the finger plate. This moving of the closing plate relative to the finger plate, closes the hook which on the up movement of the slide has been filled with material and clamps the same therein, firmly holding the bunch as the slide is moved downward and forward to bring said bunch beneath the needle. aml directly over the opening in the chute 89. The lower end of the chute is above and adjacent to a suitable supportin table 90 adjustably secured in any desired manner to the machine frame and upon which table the brush block to be filled with tufts is placed. \Vhen the slide is stopped by the engagement of the shoulder 77 with the stop plate 73, the bunch lies bet ween the end of the closing plate of the slide and the end of the plate '72 in position to be embraced by the staple as it is forced downward by the needle. 'lo release the bunch from the hook in timed relation to the movement: of the needle. the finger plate of the feed slide is moved independently of the closing plate after the latter has engaged its stop, by a bar 91 having an inwardly extending lug 92 on its lower end to engage a roller stud 93 5 on the side of said. finger plate. This releas- I ing bar is attached to one side of the vertically extending bracket forming the guide way for the head 6, by tap screws passing through longitudinal slots 9-1 and 95 in said bar, and on the side of said bar near its upper end is a laterally projecting lug 96 adapted to be engaged by an outwardly projecting stud 97 on the reciprocating head to raise the bar. A finger plate 98 is also provided on the head to engage the upper end of the bar and move the same downward as the head moves down. The stroke or movement of thebar is much less than that of the head and therefore to disengage the finger plate from the end of the bar and permit the head to pass on, in its downward movement, the slots 94 and 95 are inclined relative to the vertical path of the head so that as the bar is moved downward, it moves laterally away from the head. The lug 96 is of such length that it projects into the path of the stud 97 at all times and so upon the upstroke of the head, said stud engages beneath the lug and raises the bar.

The cam operating the feed slide, and the cam for the head are so constructed and set that the movement of thehead relative to the slide-is such that the slide is moved into position to deliver the. bunch before the delivery bar moves down to engage its lug with the stud on the finger plate and said slide is stationarily held in that position while the bunch is being released. When the bar has moved downward sufficiently to bring its lug opposite the stud, its lower end carrying said lug is swung laterally to move the finger plate, by providing an oflset or crook in the slot 94. Further downward movement of the bar carries its lug out of the path of the stud so that the feed slide may be retracted to again pick up a bunch from the hopper, the closing plate of said slide being free to rise slightly at its forward end during such movement by reason of the notch 70 at the 50 end of the slot to give the material in the hopper free access to the hook. This construction of feed'slide insures the picking up of a full bunch each time and holding the same firmly'and evenly, and taking the material from the upper side of the hopper, permits locating the hook at the'lower side of the slide so that when'said hook is opened the bunch is entirely free from said slide and its entry into the forming opening isnot 0 hindered thereby.

102 isv a spring pressed bumper traveling in a guide 103 and adapted to receive the shock of the head 6 on the return movement of the head and 104 is a similar bumper. for

5 the lever 7.

lVithin a socket formed 011 the lower end of the hopper directly below the feed slide, is an adjustable pin 105 held therein by a set screw 106. This pin is adjusted so that its upper end engages the lower edge of the feed slide and as the slide moves forward carrying the bunch of material in its holding notch, the pin will catch or scrape away any fibers that are not wholly embraced by the notch but are partially held by the notch or bunch and carried forward thereby. The pin also forms a rigid support for the slide.
