APPARATUS FOR SEGREGATING BRlSTLE-TUFTS.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed July 24, 1903. Serial No. 166,897.

To all whom it may con/corn.-

Be it known that I, HENRY NIELsoN, a subject of the King of Denmark, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Apparatus for Segregating Bristle-Tufts, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to machines for segregating tufts from a mass of bristles for use in the manufacture of brushes, its object-being to effect such segregation with facility and accuracy; and it consists of a modification of a part of the mechanism shown, described, and claimed in my application, Serial N0. 165,949, filed July 17, 1903.

The annexed drawings and the following Vdescription set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a front view of a portion of a segregating-machine embodying my invention. Fig. II represents a plan view of same, partly in section, as denoted by the section-lines 2 2, Fig. III. Fig. III represents a vertical transverse cross-section taken upon the plane indicated by the lines 3 3, Fig. I, of such portion of said machine, showing the hopper and seg- A regating member coperating therewith, such member being shown in a position intermediate of its extreme forward and rearward positions. Fig. IV represents a similar section showing said member in its extreme rearward position and in dotted lines in its extreme forward position.

A suitable hopper A is provided for feeding a mass of bristles automatically to its lower end, and operating in connection therewith and having a path of movement through such lower hopper end is a segregator B. Said hopper consists of an outer guiding member composed of two juxtaposed circularly-formed strips A A, Figs. I and III, passing from the frontof the machine toward the rear,extending downwardly and forwardly a short distance, as shown in Fig. III, and supported by two laterally-extending arms a a, Figs. I and III- These strips are formed with concave cylindrical surfaces, respectively of equal diameter, and coaxially with these surfaces is mounted a cylindrical drum E, Figs. I and III, secured to a spindle e, mounted in a bearing e',`formed upon a suitable standard F, Fig. I, such spindle extending laterally beyond the bearing, as shown in Fig. I. These cylindrical surfaces form two confining sides of an annular feedway of the hopper. To such lateral extension of the spindle e is secured a pulley t, to whose periphery is secured one end of a iiexible strap t. This strap runs over another pulley (not shown) and has attached to its other end a weight which maintains a constant pull upon the pulley t, and consequently, through the medium of spindle e upon the drum E, tending to rotate the latter, so as to cause its upper surface, as shown in III, to move clockwise.

An arm f, Figs. III and IV, extends laterally from the standard F and has secured thereon a plate f, which extends upwardly and downwardly across the space between the lower end of the members A and the drum E, as shown in Figs. III and IV. Upon the drum E and laterally of the guiding members A is mounted a circular disk A', Fig. I, slidable in the direction of the axis of the drum E and securable upon the latter by means of a setscrew a. The said disk A and guiding members A form the sides and the plate f the lower end member of the bristle hopper. That side formed by the disk is adjustable, the opposite side being open, whereby bristles of different length may be inserted into the hopper, so as to cause the middle of the bristles to fall in a perpendicular plane passing between the two strips A A, forming the guid- .Upon the drum E and secured I ing member. so as to lproject radially therefrom and transversely of the feedway of the hopper is a plate c2, which may be caused to travel through the feedway of the hopper. The upper end of the guiding member A is curved upwardly, as shown in Fig. III, to facilitate the insertion of bristles into'the hopper. To insert such bristles, the drum E is rotated so as to cause the plate e2 to clear the ends of the guiding members and so held while the bristles are inserted into the feedway between the drum and guiding members. After the required number of bristles has been inserted parallel with the axis of the drum tle latter' is released, whereupon by virtue of .the pull tles, gather, and grip a tuft.

exerted by the weight the drum turns back and causes the plate e2 to impinge the upper surface of the bristle mass and effect a pressure upon same, compressing the mass upon the lower end of the hopper.

The segregator consists of a reciprocatory segregating member consisting of a slid'able bar having suitable sliding bearing on the frame of the machine. Such bar is provided with a tooth b', forming a segregating-slot b2, whose depth may be varied by means of a 'sliding piece b3 and a screw b". In advance of such tooth is an extension If', upon which is pivoted an oscillatory cut-off member C, forming part of the segregator and provided with a shoulder c and which may be caused to intersect the plane of the slot Z22 laterally, so as to cut 0E and lock a tuft of bristles in said slot. The rear end of such cut-off member is provided with a roller b, which travels upon a runway a, formed on the frame, as shown in Fig. IV. This runway is formed with a raised or cam portion (d, which is adapted to raise the member C, so as to cut off the slot of and to cause the upper end of the shoulder to lie flush with the upper surface of bai` b, as shown in Fig. III. Suitable means (not completely shown) are provided for effecting the required reciprocation of bar suoli means being any one of many well-known forms for effecting such action. As in the form of apparatus shown in said above-named application, a stripping member D is provided which prevents superuous bristles from passing out with the bar on the forward stroke of the segregator, such member sliding upon the surface of the latter, as will be readily understood.

In operation the reciprocation of the bar Z1 causes the tooth b' to travel through the lower hopper end. Upon reaching the rearmost position, Fig. IV, cut-olf member C will have been caused to drop as a result of the disengagement of roller b with the raised surface a. The bar now being slid forward causes the tooth b to pass through the mass of bris- Upon reaching the forward end of the part of its path of travel, which is located in the hopper, the roller ascends to the raised surface o', and so effects the closure and eut-off of the said slot. On'continuing in such forward movement the rollerdcscends from said surface, and so opens the slot, whereby the tuft caught therein is released and may be extracted during the latter end of such forward stroke, the cut-off and releasing movements of the cut-off member both taking place during the forward stroke of the segregator.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1. In a machine for segregating tufts from a mass of bristles, the combination of a segregating member having a reciprocatory movement, provided with asegregating-slot, means for opening and closing such slot, and means for actuating such cut-off means to open and close during the movement of such segregating member in one direction.

2. In a machine for segregating tufts from a mass of bristles, the combination of a segre-` gating member having a reciprocatory movement, provided with a segregating-slot, means for opening' and closing such slot, and means for actuating' such latter means to both open and close during both the forward and the return strokes of such segregating member.

3. In a machine for segregating tufts from a mass of bristles, the combination with a segregating member provided with a segregatingslot, such member having a movement toward and from the front of the machine, of means for closing and opening such slot during such forward movement.

4. In a machine for segregating tufts from a mass of bristles,the combination with a segregating member provided with a segregatingslot, such member having a movement toward and from the front of the machine, of means adapted to close and open such slot during the forward movement to segregate and release a tuft and to close and open such slot during the return stroke, the construction being such that the return passage of said segregating member through the mass of bristles is accomplished without segregating a tuft therefrom.

5. Ina machine for segregating tufts from a mass of bristles, the combination of a reciprocatory segregating member provided with a segregating-slot, an oscillatory cut-off device for opening and `closing said slot, and a cam member for engaging such cut-off device during the movement of such segregating member to actuate same to open and close said slot during the movement of the segregating member in one direction.

6. In a machine for segregating tufts from a mass of bristles, the combination of a reciprocatory segregating member provided with a segregating-slot, an oscillatory cut-0E device for opening and closing said slot and pivoted to said segregating member, anda fixed cam member with which the free end of said cut-offl device is adapted to engage, the construction being such that said cut-off device is actuated by said cam member to open and close said slot during the movement of such segregating member in each direction.

Signed by me this 22d day of July, 1903.
