A CORPOEATEQN OF NEW YORK v FEEDING DEVICE FOR GLASS ARTICLES- Application filed March 11, 1931,

My invention relates to apparatus for feeding articles such as bulbs for electric incandescent lamps to machines such as incandescent lamp sealing-in machines. llhe object is to provide an a paratus whereby there will be a uniform eed of said articles presenting all of them in the same osition to the machine with a minimum 0? breakage. According to my invention, 1 provide a receptacle comprising a movable bottom, a rotatable inclined skirt surrounding said receptacle and a stationary partition mounted above said skirt. The bottom of the receptacle is gradually elevated to spill the arti- 15 cles on to the skirt and as the skirt rotates,

the stationary partition directs them down to the bottom ed e of the skirt in single file and they drop therefrom one by one on a suitable guideway. Further features and a advantages of my invention will appear from the description which follows or a s 'ecies thereof and from the accompanying drawings.

In the drawings, Fig. l is a perspective 25 view of the bulb feeding machine of my invention; Fi 2 is a side elevation partially in section 0 the operating mechanism thereof; Figs. 3, d and 5 are vertical sections through my machine in various stages of op- 39 oration; and Fig. 6 is a plan view of my machine while in o eration.

The lamp bu bs 10 which are to be fed by my machine are placed in the receptacle ll which has a cone-shaped bottom 12 as shown in Figs. 1 and 3. The machine is then started and the bottom of the receptacle is caused to rise until a number of bulbshave tumbled over the top edge of the said receptacle upon the skirt 13 whereupon the bottom is lowered somewhat. The risingjaction reduces the arrangement and disposition oi parts illustrated in Fig. 4,.and the lowering alters thisto that shown in Fig..5. The motion of the bottom 12 of the receptacle is produced by the mechanism shown in Fig. 2 which is operated by cams 14 and 15 on shaft 16. This shaft is preferably a portion oil the machine to which my machine feeds the bulbs and has intermittent movement. The receptacle hot- 50 tom 12 is raised by lever 17 which engages Serial li'o. 521,316,, and in Japan. Harsh 20, 1830.

the notched portion 18 oi rod 19 through is engaged by cam 14:

pawl 20 and which The pawl 20 is kept through roller 21. against the rod by spring full weight of the bottom during its upward and downward movements. On the completion of the downward movement the clutch housed in box 23 engages the rod 19 thereby allowing pawl 20 to move down a notch on rod 19. When roller 2% is against the low part of earn 15, clutch box 23 which is connected to lever 25 through pin 26 position illustrated. In this position, balls 27 of the clutch do not engage rod 19 as the inclinations of the upper surfaces of blocks 28 and 29 cause them to roll away from said rod. When the clutch box 23 and associated parts are in this position. The rod 19 and parts attached thereto are supported by pawl 20. When the roller 24 is in en agement with the high portion of cam 15, t e clutch box 23 is in a. raised position and the blocks 30 and 31 which have inclined inner surfaces force the balls 27 into engagement with rod 13..

The. lamp bulbs 10 which have fallen on to the skirt 13 slide, on account of its conical shape, against the stationary partition- 22 and carries the is in the- 32 which is spiral and provides a spiral path on the upper surface of said skirt, as

shown in Fig. 6. The rotation or" the shirt by belt 33 causes the bulbs to be directed by the partition 32 down a spiral path to the edge ot the s irt where they are swept ed on to rods 3 and by plate 36. llhe bulbs are automatically arranged by this movement into a single file. The outer ends of rods 34 and 35 are supported by yoke 37 on rod 38 which is attached to table 39 by bracket 4.0 and the inner ends of said rods are supported by bracket 41 which is attabbed to table 39. The end of the partition 32 is supported by bracket 42 and the various loops thereoi are fastened together by straps t3 and Belt 33 which turns shirt 13 is operated throu 'h pulley 45 on shafted which is operated rom some external source through bevelgear t7 and which is supported b brackets What claim asnew'and desire to secure 48 and 49 from the table.

. by Letters Patent of the United States is:

1. An apparatus for feeding bulbs and similar articles comprising a rece tacle having a movable bottom, an incline skirt surrounding said receptacle, a stationary partition mounted over said skirt, means for causing a gradual elevation of said bottom and means for rotating said skirt.

2. An apparatus for feeding bulbs and similar articles comprising a receptacle having a movable bottom, a conical skirt surrounding said receptacle, a stationary partition mounted over said skirt, means for causing a gradual elevation of said bottom and means for rotating said skirt.

3. An apparatus for feeding bulbs and similar articles comprising a receptacle having a movable bottom, an inclined skirt surrounding said receptacle, a stationary spiral partition mounted over said skirt, means for causing a gradual elevation of said bottom and means for rotating said skirt.

4.An apparatus for feeding bulbs and similar articles comprising a receptacle having a movable bottom, an inclined skirt surrounding said receptacle, a stationary partition mounted over said skirt, means for causing a reciprocation and gradual elevation 0 said bottom and means for rotating said skirt.

5. An apparatus for feeding bulbs and similar articles comprising a receptacle having a movable bottom, a conical skirt surrounding said receptacle, a stationary spiral partition mounted over said skirt, means for causing a gradual elevation of said bottom and means for rotating said skirt.

In witness whereof I have hereunto set my hand.
