INCL, OF TROY, NEW YORK, A CORPORATION OF NEW YORK BBISTLING LEACHINE Application filed August 4, 1931.

In bristling machines with which I am familiar, it has been usual to provide a carrier which selects from a magazine a sufficient number of bristles to form a tuft, and

transfers the bristles so selected to a nozzle from which they are inserted in an opening in a brush support. Difiiculties have been inherent in such a machine as the bristles in the magazine at times become tangled with the result that a. fewer number of bristles than are sufficient to form a proper tuft are elected from the magazine with the result that the tuft is thin and unsatisfactory. Furthermore, the provision of a carrier requires 5 an exact timing of the movement of the carrier with respect to the other parts of the machine all of which tends to complicate the same. 7

One of the objects of my invention is the provision of a bristling machine which dispenses entirely with the carrier, thereby greatly simplifying the construction of the machine and increasing the speed of operation thereof.

Other objects of my invention will appear in the specification and will be particularly pointed out in the claims.

My invention will best be understood with 30 reference to the accompanying drawings in which I have illustrated a preferred embodlment of my invention and in which Fig. 1 is a front view of a bristling machine embodying my invention;

Serial No. 555,041.

Like reference characters indicate like parts throughout the drawings.

Referring now to the drawings 10 is the frame of the bristling machine, provided with laterally extending arm 11 which forms a guide for the actuating bars 12 and 13 for the nozzle 14 and the plunger 15, respectively. Stationary bar 16 also forms a guide for the actuating bar 12, while a movable guide bar 17 is secured to the actuating bar 12, as by a screw 121 and moves therewith while the free end of the bar 17 forms a guide for the actuating bar 13.

he bars 12 and 13 are actuated by cam discs 18 and 19, respectively, which are mounted upon a shaft 20 having its bearings at 21 in standards 22 on the frame 10. The cam disc 18 is provided with a cam groove 23 (indicated in dotted lines in Figs. 1 and 2) in which is received a roller 24 mounted on the upper end of the actuating bar 12 as best shown in Fig. 2. The cam disc 19 is likewise provided with a cam groove 25 in which is received a roller 26 mounted on the upper end'of the actuating bar 13. The shaft in the embodiment illustrated is actuated by a pulley 27 from any suitable source of power.

The nozzle14 is mounted on an arm 28 which is in turn mounted on the lower end of the actuating bar 12. The nozzle is preferably formed of two sections 141 and 142 as well shown in Fig. 4 which may be suitably secured together as by clamping screws (not illustrated). The section 142 of the nozzle is provided with a. T-shaped groove 29 extending longitudinally thereof and in which is received the lower end of the plunger 15 and which lower end conforms in contour to that of the groove. The lower end of the plunger 15 is provided with a V-shaped recess 30 for a purpose which will be more fully hereinafter described.

The other section 141 of the nozzle is provided with a recess 31 for the reception of a die plate 32 provided with an opening 33 which registers with the groove 29. The section 141 of the nozzle is provided with a groove 34 in which is received an anchor forming metal strip 35, andwhich is fitted into the groove ina well known manner and by mechanism which is not illustrated. A. plunger 36 is provided at its inner end with a punch 37 adapted to pass through the opening 33 and sever from the metallic strip 35 an anchor which passes through the die plate. The plunger 36 may be actuated by any suitable mechanism, which in the embodiment illustrated, comprises an arm 38 pivoted as at 39 on a bracket 40 secured to the nozzle. The plunger 36 may pass through a disc 41 pivoted as at 42 on the arm 38. The arm 38 may conveniently be moved by stationary cam members 43 and 14: as indicated in 1, it being understood that when the nozzle together with the arm 38 is elevated, the roller 15 on the free end of the arm engages the cam member i3 and moves the plunger inwardly, the punch on the end thereof thereby severing an anchor from the metallic anchor strip and forcing it through the opening 33 in the die plate 32 and into the groove 29 on the opposite side of said plate. lVhen the nozzle descends, the engagement of the roller $5 with the cam 4% forces the plunger and the punch outwardly away from the anchor strip.

In the embodiment of my invention illustrated the nozzle 14: moves along a portion of a magazine 16 in which bristles 47 are disposed transversely as indicated in Fig. 2. Bristles of any desired character, for example, animal hair, tampico or other fibrous bristles or wires may be used. It will be understood that the bristles may be manual- 1y placed in the magazine or fed thereto in any desired manner. The lower end of the magazine 46 is preferably provided with a laterally extending portion 18 comprising upper and lower bars or plates 49 and 50 each provided with a recess 51 as best shown in Fig. 8 in which is received a rib 52 on the nozzle, and which is preferably formed with an extension 521 above the main body of the nozzle as bestshown in Figs. 3 and 4. By providing a recess 51 which extends inward- 1y beyond the face of the nozzle, the bristles are retained in parallel relation within the magazine better than would otherwise be the case.

The nozzle comprising the rib 52 is pro vided with a slot of predetermined fixed dimensions indicated generally at 53 having an inclined portion 531 and a vertical portion 532, the vertical portion of the slot containing only a sufficient number of bristles to form a tuft. The entire slot therefore, including the inclined portion and the vertical portion contains a number of bristles in ex:- cess of the number required to form a tuft, and acts as a magazine in itself.

The portion 522 of the rib which is above the slot is offset from the portion 523 below the slot as best shown in Fig. 2 so that as the rib moves upwardly in engagement with the bristles, the latter are forced into the slot to fill the same. Furthermore the distance which the nozzle moves is greater than the length of the slot. I have found in practice that such a distance may be approximately four times as great as the length of said slot. In case, therefore, a portion of the bristles in the magazine are tangled or otherwise dislodged from their normal positions, the slot will be filled properly with bristles, as the slot will move past other bristles which lie I in parallelism transversely of the slot.

The bristles in the magazine may be compacted by a suitable follower weight 54;. It will be understood that the bristles are also evenly compacted in the slot 53 due to the upward movement of the nozzle in engagement with the bristles, the offset upper por tion of the rib causing the slot to engage the bristles and force them into the slot at a sub stantially uniform pressure.

.Vhen the punch 37 severs the lower end of the metallic strip, it forms an anchor 55 which is forced through the opening 33 into the groove 29 in front of the plunger 15 and above the bristles in the vertical portion 532 only of the slot, so that when the plunger is forced downwardly relatively to the nozzle, the anchor forces downwardly the bristles only which are in the vertical portion of the slot and doubles the bristles over the anchor as illustrated in dotted lines in Fig. 5 to form a tuft. The nozzle and the plunger then descend together until the end of the nozzle is located adjacent one of the openings 50 in a brush support 57 (see Fig. 2). The plunger then is moved downwardly relatively to the nozzle and forces the tuft of brlstles with the anchor into the opening.

In accordance with my invention, means are provided for varying the number of bristles that make up a tuft. In the embodiment illustrated, angle plates 61 are provided, one flange of each of which is adjustably secured to the nozzle. as by set screws indicated in Fig. 3, the other flanges overlying a part of the vertical portion 532 of the slot. By vertically adjusting the plates 61, the number of bristles contained in the vertical portion 532 of the slot 53 and, correspondingly, the number that make up a tuft, may thus be varied.

A stated above, the bottom of the plunger 15 is preferably provided with a V-shaped recess 30. The upper edge of the anchor 55 which is preferably rectangular in cross section, is received in the recess 30 thereby preventing the edge of the anchor from being turned out of engagement with the lower .id of the tongue or plunger. \Vith a square end, in case the anchor is not properly centered in the opening, there is danger of its tilting so that the upper edge of the anchor leaves the end of the plunger entirely, thereby incurring the danger of the tuft being insecurely p tioned in its opening, and of the plunger itelf being broken. The provision of the V shaped recess which, it will be noted,

is formed in the end of the main body of the plunger and the rib, overcomes the foregoing difiiculty.

The operation of the device embodying my invention will readily be understood from the foregoing description and is as follows:

Assuming that the parts occupy the positions indicated in Figs. 1 and 2, the rollers 24: and 26 which actuate the nozzle and the plunger respectively are located in the lower portions of the respective cams 23 and 25. At this time the slot 53 has been filled with bristles by the upward movement of the nozzle in the manner heretofore described. The upward movement of the nozzle has also caused the roller 45 on the arm 38 to engage the cam member 43 and force the plunger 36 and the punch 37 to the right as viewed in Fig. 5 and thereby sever an anchor 55 from the metallic strip 35 and force it through the opening 33 in the die plate 32 and into the groove 29 underneath the plunger and above the bristles in the vertical portion 532 of the slot 53. Now as the rotation of the cam discs in a clockwise direction as viewed in Fig. 2, as indicated by the arrow in Fig. 1, is continued, roller 24 is forced downwardly while the roller 26 remains substantlally stationary for an appreciable period as will be apparent from the inspection of the cam grooves 23 and 25 thereby forcing the plunger 15 and the anchor which is in front of the same, downwardly relatively to the nozzle which remains substantially stationary for an appreciable period, thereby segregating the bristles in the vertical portion 532 of the slot 53 from the bristles in the inclined portion 531. The bristles 47 are thereby folded over the anchor as indicated in dotted lines in Fig. 5. The nozzle with the plunger is now forced downwardly together until the lower end of the nozzle engages, or substantially engages the upper face of the brush support 57, with the groove 29 immediately above the opening in which the tuft of bristles is to be inserted. It will be understood that this portion of the operation is taken care of by the movement of the brush support in a manner which is well understood in the art. The continued movement of the cam discs again forces the plunger downwardly relatively to the nozzle thereby inserting the anchor with the bristles folded thereover in the desired opening. The plunger is then withdrawn into the nozzle, the nozzle and the plunger move upwardly and finally the plunger again moves upwardly relatively to the nozzle to complete the cycle of operations and leave the parts in the positions indicated in Figs. 1 and 2.

V'Vhile I have described my invention in its preferred embodiment, it is to be understood that the words which I have used are words of description rather than of limitation and that the drawings are merely illustrative.

Hence, changes within the purview of the appended claims may be made without departing from the true scope and spirit of my invention.
