MACHINE FOR BUNCHING HAIR-PINS.

Specification of Letters Patent.

Application filed May 17, 1917. Serial No. 169,372.

To all whom it may concern: I

Be it known that I, IRVING H. PEoK, a citizen of the United States, residing at Derby, county 'ofNew Haven, State of Connecticut, have invented an Improvement in Machines for Bunching Hair-Pins, of which the following is a speclfication.

This invention relates to certain improve ments in the machine for bunching hair pins for which Letters Patent No.-672,330, were granted to me April 16, 1901, and the invention has for its object to overcome certain objections inherent in my said former machine, and to effect a great saving in the cost of packing hair pins by providing a machine that will enable a single operator to handle several times as many hair pins as was pos sible with my said former machine and likewise, if required, to bunch and pack a plurality of sizes of hair pins simultaneously. One of the trade requirements at the present time is packages containing a predetermined number of four sizes of hair pins, and in the drawings I have illustrated a machine organized to bunch four sizes of hair pins simultaneously.

The selecting mechanism of my present machine is substantially the same as in my former machine. It has proved an objection to the rapid working of my former machine that the hair pins, which were fed to the carrying belt in bulk, were apt to collect together in tangled masses which were carried up by the buckets, but were not separated by the inclined troughs and consequently, were not caught by the selecting track, but fell upon an incline below the track by which they were returned to the hopper and were repeatedly carried u by the belt and dropped upon the inclined troughs in masses. This objection is wholly overcome in my present machine by the use of novel feeding mechanism, an essential feature of which is a separating drum or a plurality of drums by which the hair pins are separated from each other so that they will pass to the belt singly and the carrying up of masses of hair pins by the belt is wholly avoided.

In the accompanying drawings forming a part of this specificatlon,

20 denotes the casing of the machine and 21 a shaft which extends through the casing and carries within the casing a pulley or drumv 22, over which a compound belt 23 passes. I term this a compound belt, for

the reason that it carries a plurality of sets of buckets 24, which are secured to the belt in'longitudinal alinement. The belt passes upward from pulley 22 and over a plurality of idler pulleys 25 between which the buckets pass in dumping position then over an idler pulley or drum 26, then backward over an idler pulley or drum 27 and over pulley or drum 22 again.

Power is applied by means of a belt, not

shown, passing over a pulley 28 on the shaft,

sists of an end piece 33 having a feeding opening 34 registering with the opening 31 in a housing, a closed end piece 35 and a plurality of slats 36 secured to the end pieces. The inner face of each slat consists of inclines 37 which meet at an angle. Between the slats are spaces 38, each of which permits a hair pin to pass through easily when in longitudinal alinement with the space. Two housings are placed side by side on each side of the casing. The separating drums in the two inner housings are carried by shafts 39, journaled in'bearings 40, secured to the rear ends of the housings. Each shaft carries a belt pulley 41, over which and over the corresponding pulley 29 a belt 42 passes, and also carries a belt pulley 43. The sep-. arating drums in the .two' outer housings are carried by shafts 44 having belt pulleys 45, overwhich, and over belt pulleys 43, belts 46 pass. y

The space within the casing in front of the compound belt is divided by vertical partitions 47, into four compartments, each compartment having an inclined bottom 55 and corresponding with one of the separating drums and containing one of the sets of buckets on the compound belt.

As already stated, hair pins of a certain size are fed to each separating drum in bulk, it being, of course, immaterial whether the same or differentsizes of hair pins are supplied to the several drums, as the hair pins from each drum remain separated from hair pins from the other drums while being operated upon by the selecting and bunching mechanisms, presently to be described.

The action of the separating drums is to tumble the masses of hair pins about to separate them. The hair pins as they are tumbled about in the drums, continually fall back upon the angles of the slats, the effect of which is to disentangle the mamas and to ultimately cause each hair pin to he brought into longi-.

tudinal alinementv with a space between the slats, when it will drop out from the drum. The drums and slats are so proportioned as to provide plenty of spaces for the hair pins to pass out so that, as a matter of fact, the hair pins are supplied quite as fast as they can be taken up by the compound belt and disposed of by the selecting and bunching mechanisms.

The hair pins from each separating drum drop into a special chute and are conducted thereby to a special compartment 47 in the casing, and to a special set of buckets on the compound belt. The chutes from the two outer housings are indicated by 48, and the chutes from the two inner housings by 49, see Fig. 1 in connection with Fig. 6, which shows the opening into the corresponding compartment of one of the chutes .49, in the present instance, the chute 49 at the right in Fig. 1. The configuration and inclination of the chutes is such as to prevent any massing of the hair pins therein. This will be obvious from the fact that the'scale of Fig. 10 is approximately double the scale of Fig. 6. In practice, the separating drums effectually separate the individual hair pins from the masses therein, so that they will mes es drop out from the drums singly and pass down the chutes singly to the buckets by which they are carried upward.

The selecting mechanism-This mechanism differs in details only, from the selecting mechanismof my former patent. The belt is driven with sufficient speed to cause the hair pins in the buckets to be expelled therefrom as the buckets pass idlers 25 and to drop upon outwardly inclined shallow troughs 50, which they slide down and drop upon inwardly inclined troughs 51. These troughs are each provided with a central longitudinal alining groove'52 into which the hair pins are caused to pass by the inclined side walls of the troughs, and from which the hair pins drop upon inclined selecting tracks 53. The hair pins which drop I from troughs 51 with the looped ends downtion. The selecting tracks are carried by rigid plates 57 which extend upward from an inclined wall 58. Operating in connection with each selecting track, is a cage 59 and a cut-off 60. The gages are adjustably secured to slides 61, which are adapted to reciprocate in a guide plate 62 secured to wall 58. The cut-offs are provided with shanks 63 which have longitudinal movement in slides 64, themselves adapted to reciprocate in the guide plate. Coil springs 65 surrounding the shanks bear a ainst the cut-'ofi's and against the ends of slides 64, .and act to retain the ClltrOfiiS at their forward position. 66 denotes horizontally disposed levers pivoted to the guide plate, the respective ends of which are pivotally con nected to slides 61 and 64. The rear ends of slides 64 are pivotally connected to vertically disposed levers '67, themselves pivoted to a vertical wall 68. The lower ends of levers 67 are pivoted to a slide 69, adapted to reciprocate in the side walls of the easing. Movement is imparted to slide 69 to.

cut-ofl and slide down on the track until stopped by the gage. The operator now presses down on the treadle, which instantly causes each cut-off to pass between two halr pins on the track, springs 65 on the cut-ofi's yielding as the gages move away from the tracks. The hair pins below the cut-offs now slide down past the gages and are bunched on hooks 74 at the lower ends of thetracks, as in Fig. 10. The instant the treadle is released, spring 73 will cause the gages to engage the tracks again, but sprlngs 65 will retain the cut-ofi's in engagement with thetracks long enough to prevent hair pins from passing the cut-offs until the gages are in position to stop them, it being understood that owing to springs 65, the cut-offs have less movement, away from the tracks, than the gages. The operator sitting at a table 75, takes the bunched hair pins from the hooks and packs them as may be required. Each operation of the treadle causes the predetermined number of hair pins for a bunch to be separated by each cut-off, and then to pass the gage and slide down on the hook. Release of the treadle causes the gages to engage the selecting tracks again, and an instant later the cutoffs permit hair pins on the'tracks to pass down to the gages a ain.
