.To all whom 'it may cioncem:-

Be it known that we, ORLANDO B. HOOVER and MONROE CURRY, citizens of the United States, and residents of Killeen, in ,the county of Bell and lState of Texas, have made certain new and useful Improvements in Machines for Filling Brushes, of which the following is a specification.

Our invention is an improvement in machines for filling brushes, and consists in certain novel constructions, and combinations of parts, hereinafter described and claimed. l

The object of the invention is to provide a simple ellicient machine of the character specied which will be especially adapted for filling with bristles, brushes for clothes, hair, or gins, and for securing the bristles in the'article.

Referring to the drawings forming a part hereof, Figure 1 is a front view of the improvement partly in section, Fig. 2 is an enlarged sectional view of a portion of Fig. 1 showing the mechanism in one position, Fig. 3 is a similar view showing the mechanism in another position, Fig. 4 is an end view of the improvement with the brush partly in section, Fig. 5 is a similar view of the lower portion of Fig. 4 showing the cam in another position, and Fig. 6 is an edge view of the cam. t

In the embodiment of the invention shown in the drawings, a supporting frame is provided, the said frame consisting of end plates 1, and atable 2 supported by the end plates, the bottom of the said plates being connected by rods 3, one of the ends of each rod being threaded and engaged -by a nut 4.

Each of the end plates 1 is provided near its lower end with a bearing 5, and a shaft 6 is journaled in the bearings. The ends of the shaft are extended beyond the end plates, and one of the ends is rovided with a pulley 7 loosely journaledD thereon, .while the other is provided with a crank disk 8 secured thereto. f

The hub 9 of the pulley is provided with clutch teeth 10 at its inner end, and a sleeve 11, slidable on the shaft but constrained to rotate therewith, is provided with clutch teeth meshing therewith, when the -sleeve is moved toward the pulley. The sleeve is provided with an annular groove l2, and a lever 13 is pivoted to an arm 14 on the adj acent end plate, and is provided with a fork 15 engaging the groove. The opposite end pulley may be connected and disconnectedwith the shaft.

Intermediate its ends the shaft is provided with a crank arm 17, and-adjacent to the pulley 7 a bevel gear wheel 18 is secured to the shaft by a set screw 19. A vertical shaft 20 is journaled in bearing arm 21 on' the end plate adjacent to the pulley, and in a bearing 22 in the table and its lower end is provided with a bevel gear wheel 23 meshing with the bevel gear 18. The upper end of the shaft 2O extends above the table 2, and is provided with a crank vdisk 24, and directly above the crank arm 17, a cylinder 25 is secured to the under face of the table top by means of nuts or bolts 26, passing through an annular flange 27 on the cylinder and engaging the table. A pair of arms 28 extend downwardly from the lower end of the cylinder, and each is provided with a bearing 29 engaging the shaft 6, one bearing being upon one side of the crank arm, and the other bearing on the other side. A piston 30 is movable in the cylinder, and a pitman or piston rod 31 connects the piston with the crank. p

The cylinder is provided at one side near its upper end with an outlet pipe 32, and on the other side with an outlet valve. rlhe said valve comprises a nipple or cage 33 ar ranged over an opening 34 in the cylinder, and a valve 35 normally closes the opening and is provided with a stem 30 passing through the outer end of the cage. The st-em is also provided with a collar 37, and a spring 38 is arranged between the collar and the end of the cage, and normally holdsI the valve closed, but permitting it to open when the piston moves upwardly.

A small cylinder 39 is arranged on the top of the table at the end adjacent to the crank disk 8, and the pipe 32 is provided with an elbow 40 leading into the cylinder. A nozzle 41 is fitted tightly but slidably l,into the outerend of the cylinder and is Yprovided with a pin 42 extending through a slot 43 in the cylinder. A link 44 is provided at each end with an opening, one fitting over the pin 42, and the other over the wr1st pin 45 of the crank disk 24.

A washer 46 is arranged on t-he pin 42 below the link, and a key 47 traverses the 'pin above the link. It will be evident that when Vthe crank disk 24 rotates, the nozzle will be on the under side. A magazine or holder 54 for the bristles 55 is arranged beyond the nozzle, and the magazine is provided with a flanged opening 56 in its side, through which the reduced portion of the nozzle passes when it is inthe position shown in Fig. 2.

The table 2 is extended beyond the end plate toward and against the magazine as shown, and is provided with an opening 57 directly below the opening 56, and in the space below the extension, and between the end plate and the magazine, the articles 58 to be filled with bristles are placed, with the openings 59, for the bristles in register with the opening 57.

A needle holder` 60 is Slidable vertically in bearings 61 on the end plate, and is provided in its upper end with an opening for receiving the needle 62, which is secured in place by a set screw 63. The needle is provided with an eye 64 for receiving the twine 65, and the holder is reciprocated by'means of` a pitman or link 66, connected at one end with the wrist pin 67 of the crank disk 8, and at the' other to a pin 68 on the needle holder, a key 69 passing through the pin to hold the pitman in place.

The needle is operated by means of a shaft 73, .journaled longitudinally of the frame near the bottom thereof and having secured to one end outside of the frame a disk 74, provided with a wrist pin 75, and a link 76, connects the wrist pin with the needle holder 60. A cam wheel 77 is also secured to the shaft between the disk and the frame 1 and the said wheel is provided with two

cams

78 and 79. A lever 80 is provided at approximately its center with a longitudinal slot 81, which is engaged by a pin 82, on the frame and near its lower end'the lever is provided with an angular portion or arm 83. A spring 84 is connected at one end with a pin 85, on the lever and at the other lwith a frame and normally holds the lever in the position shown in Fig. 4. The upper end of the lever is pointed as shown at 86, to enter the openings 59 for receiving the bristles 55. By means of the cams 7,8 and 79, a vertical movement is imparted to the lever 80, and also a vibrating movement on the pin 82. The needle holder 60 is slidable in bearings 87 on the frame, and .an eye 88Ais provided on the frame adjacent to the needleholder through which the twine passes before it I reaches the eye on the needle holder and the eye 88 is slightly /below the eye 70, when the needleholder is in its upper-most position.

In operation, the holder being filled with bristles, the shaft 6 is clutched to the pulleyTA which is connected with any suitable source off power. The rotation pf the shaft creates a vacuum in the cylinder 25, since the air is free to pass outthrough the valve, but is not permitted to enter. The nozzle is moved toward the holderv or magazine, and enters through the opening 56. The needle mean'- while has moved upward, and the reduced portion of the nozzle passes through the loop of thread -formed in the thread. The reduced portion passes on into the holder, and just as it is well entered the lateral opening 49 comes into register with theelbow 40, and the air rushesthrough the opening 53 of the nozzle to fill the vacuum in the` cylinvder 25. The current of air carries a tuft of bristles with it, and the bristles enter the reduced portion until the ends thereof engage the shield or stop 51. The nozzle continues its outward movement until the tuft assumes a position transverse to the opening 57 in the table. The needle during the above described movement Aof the nozzle has' moved downward, and the tension onthe twine or thread 65 draws the bristles through the opening 59 of the article 50, in a doubled condition as shown in Fig. 3.

The above described process is repeated for each opening of the article, until it is filled with bristles, the article being moved as the filling progresses. Any suitable tension means may be provided for the thread, and it is passed through a guide eye 70 on the holder to the needle.

A stirring rod or needle 71 is secured to the pitman 66 as at 72, and passes upwardly through an opening into the holder. The needle assists in feeding the bristles downward in the magazine. When the machine is in operation, the cam 79 strikes the lateral arm 83 (see Fig. 5) raising-the lever 80 and causing the point 86 to enter one ofthe openings 59 in the brush. As the point enters the opening the cam 78 strikes the lower end of the lever, and moves the said lower end laterally, thus feeding the brush 58 laterally and bringing another opening into position to be filled with bristles.
