The present invention relates to apparatus for feeding articles in a predetermined oriented position to an articlefabricating machine and, more particularly, to apparatus for feeding intermediate contacts to a base-making machine for the fabrication of bases for Three-Lite incandescent lamps.

Heretofore, the above-mentioned intermediate contacts Henry 1?. Hasell,

were of the type shown in US. Patent No. 2,519,328,

issued April 15, 195%, to J. B. Whitmore et a1. These intermediate contacts were formerly fabricated in the form of a ring provided with a center opening. Upstanding from the periphery of this center opening, tapering curved and inclined lugs were provided for embedding in a glass insulator which insulates the center contact or eyelet from the intermediate contact. Embedding of the lugs in the glass insulator produced strains in the glass with resultant base shrinkage due to center eyelet crack-off thus causing the substitution of prongedhollow bosses for the lugs.

One of these pronged bosses is used as a substitute for an apertured frustoconical hollow boss previously provided in the patented intermediate contact, which pronged boss must be oriented in a predetermined position to receive a lead wire of the lamp. To provide the above'mentioned circular configuration these intermediate contacts are fabricated individually on a punch press from a strip which is wider than the diameter of the intermediate contact and the successive punchings are spaced a predetermined distance apart thereby resulting in considerable residual scrap in the strip from which they are punched.

T he intermediate contacts are fed to a basemaking machine of the type described in US. Patents Nos. 1,210,237 and 1,210,238, issued December 26, 1916, to T. 1. Walker et al., by feeding apparatus of the type shown in U .S. Patent No. 2,519,328, issued August 15, 1950, to I. B. Whitmore et al. In such conventional feeding apparatus, the intermediate contacts are fed individually from a hopper along a slide into a pocket on a rotatable reservoir dial which indexes such intermediate contacts to a further work station Where a first transfer means transfers these contacts to a turning head. A holding plunger in the turning head secures the intermediate contact while a rotating locating pin enters the lead-wire boss to orient such contact in the predetermined oriented position which it is to occupy in the bottom die of the base-making machine. Thereafter, a second transfer means transfers the oriented intermediate contact from the turning head into the bottom die. The primary disadvantage of this conventional feeding apparatus is its inability to feed the intermediate contacts individually from the hopper into the pockets on the reservoir dial. The presence of the upstanding lugs or pronged bosses on the intermediate contacts and the relative resiliency and readily deformable nature of such intermediate contacts causes them to become commingled and entangled with the result that the feeding apparatus occasionally fails to feed an oriented intermediate contact to the base-making machine. Because of their fragility and small size, hand feeding of the oriented intermediate contacts onto the pockets er the reservoir dial at a rate of 40 insertions per minute has been found to be inefiicient.

This conventional feeding apparatus is also limited in its speed of operation by the minimum time required for its moving elements to perform their above-described tasks and hence is limited to production rates in the neighborhood of about 4t) bases per minute. With the present trend in the industry toward higher production rates in the neighborhood of 65 bases per minute such conventional feeding apparatus has been found inadequate. In addition, the complexity of the apparatus and its many moving parts result in a high initial cost, considerable maintenance eX- pense and resultant loss of. production time.

It is the general object of the present invention to avoid and overcome the foregoing and other diiiiculties of and objections to prior-art practices by the provision of an improved apparatus for feeding articles in a predetermined oriented position to an article-fabricating machine, which feeding apparatus will operate efficiently at a high production rate.

Another object of the present invention is the provision of an improved feeding apparatus which will accept a continuous strip of articles disposed in a predetermined oriented position thereby eliminating the complicated and expensive article-orienting means heretofore employed.

Still another object of the present invention is the provision of an improved apparatus for feeding intermediate contacts to a base-making machine, which feeding appa:

ratus is adapted to operate satisfactorily with a continuous strip of octagonal-shaped intermediate contacts thereby providing a 30% reduction in the scrap metal in the original strip by permitting the intermediate contacts to be punched from a strip of metal having the same width as the intermediate contact and by eliminating any web between adjacent punched intermediate contacts and also permitting such feeding apparatus to sever the intermediate contacts from the continuous strip with a single cut.

Yet another object of the present invention is the provision of an improved feeding apparatus which is adapted to receive a continuous strip of intermediate contacts thereby permitting the use of a positive feeding means and resulting in a higher equipment efficiency and a higher production rate.

A further object of the present invention is the provision of an improved feeding apparatus which is operable to receive an intermediate contact from a continuous strip of such intermediate contacts oriented in a predetermined position and to transfer an intermediate contact to the bottom die of a base-making machine where such intermediate contact because of its octagonal shape will remain locked in the oriented position.

The aforesaid objects of the present invention, and other objects which will become apparent as the description proceeds, are achieved by providing an improved apparatus for feeding articles to an article-fabricating machine, which feeding apparatus comprises means for presenting a continuous strip of such articles arranged in a predetermined position successively to a position adjacent a movable support where a transfer means secures the supported leading article and where a cutting means severs the supported and secured article from the strip thereby permitting the transfer means to deposit the article without further orientation into the article-fabricating machine.

For a better understanding of the present invention reference should be had to the accompanying drawings wherein like numerals of reference indicate similar parts throughout the several views and wherein:

FIG. 12 is a fragmentary perspective view of a finished Three-Lite incandescent lamp to which the finished base is attached.

Although the principles of the present invention are broadly applicable to apparatus for feeding articles in a predetermined oriented position to an article-fabricating machine, the present invention is particularly adapted for use as apparatus for feeding intermediate contacts in a predetermined oriented position to a machine for fabricating bases for Three-Lite incandescent lamps and hence it has been so illustrated and will be so described. With specific reference to the form of the present invention illustrated in the drawings, and referring particularly to FIGS. 1, 2 and 5, a continuous strip of octagonal shaped intermediate contacts 10 (for use individually in a base 12, FIG. 12, for a Three-Lite incandescent lamp 14) is indicated generally by the reference numeral 16.

The intermediate contacts 10 are punched from the continuous strip 16 (which has the same width as the intermediate contacts 10) without a web between adjacent intermediate contacts 10 thus permitting the feeding apparatus of the present invention to sever the intermediate contacts 10 from the continuous strip 15 with a single cut as hereinafter explained, resulting in a 30% reduction in the scrap metal produced in the fabrication of the priorart strip, and permitting the reeling of such continuous strip 16. The intermediate contacts 10 are joined end-toend on the continuous strip 16 and are provided, as a result of a conventional punching operation (not shown), with a center opening 18 (FIGS. 2 and 5) which is to be filled with a glass insulator 20 (FIG. 12) and are provided with three pronged bosses 22a and 22b (FIG. 5) for embedding in the glass insulator 2G. The pronged boss 22a is utilized for receiving a lead wire (not shown) of the lamp 1 5 and, as a result, must be fed to a head 24 (FIGS. 1-5 and 8-10) with such pronged boss 22a in a predetermined oriented position, the head 24 being disposed at station 1 (FIG. 11), the intermediate contact feeding station of a conventional base-making machine 26 (of the type shown in the above-mentioned US. Patent Nos. 1,210,237 and 1,210,- 238).

It will be understood from a consideration of FIGS. 2 and 5 that since the intermediate contacts 10 are joined end-to-end on the continuous strip 16, the lead-wire pronged bosses 22a in such intermediate contacts 10 are all arranged in a predetermined position with respect to each other, namely, on the left-hand portion of the intermediate contacts 16 in radial alignment with the center opening 18, thus permitting the use of a positive feeding means (as hereinafter explained) and eliminating the need for conventional complicated and expensive contact-orienting means as heretofore employed.

In order to load the continuous strip 16 of intermediate contacts 10 into the feeding apparatus of the present invention, the free end of such continuous strip 16 is passed over a guide roller 27, between a pair of guide rollers 23, FIGS. 1 and 2, and between a pair of drag rollers 2 of a conventional drag unit 39 mounted on the frame portions 32 of such feeding apparatus. This drag unit 30 is utilized in the conventional manner for braking the continuous strip 16 during the advancement thereof (as hereinafter explained) to prevent buckling of such continuous strip 16. Such free end is then inserted into a guide channel 34, FIG. 7, provided in the top face of a supporting block 36 (also secured to the frame portions 32) and is moved successively beyond a holding pawl 33 and an advancing pawl 4%? of a strip-advancing mechanism 42 (FIG. 1) until the forward face of the leading intermediate contact 10 on such free end of the continuous strip 16 is positioned, as shown in FIGS. 1 and 2, in registry with a stationary cutter i l (H68. 1, 3 and 8-10). This stationary cutter 44 is mounted on a re movable adjustable block 46 secured to the forward end of the supporting block as, which mounting of the removable block 46 permits adjustment and replacement of the stationary cutter 44.

This strip-advancing mechanism 42 is operable to advance the leading intermediate contact 10 a distance al from the position shown in FIGS. 1 and 3 to the position shown in FIG. 8, in which position such leading intermediate contact 119 is supported by a movable support 48 and is oriented with respect to a transfer head 50 and a movable cutter 52 thereabove and a head 24 therebelow at station 1.

Strip-advancing mechanism The holding pawl 33 associated with the strip-advancing mechanism 42 is pivoted on the supporting block 3:5 at 54 (FIGS. 1, 2 and 3) and is spring-biased in clockwise direction through an operating slot 56 provided in the supporting block 36 and into a center opening 18 in the fourth intermediate contact 19 disposed thereabove on the supporting block 36 and to engage the left-hand side, as shown in FIGS. 3, 5 and 10, of such center opening 18. To provide stop means for the clockwise urging of the spring biasing on the holding pawl 33, the right-hand heel of such holding pawl 38 engages the underside of the fourth intermediate contact 10, as can be seen in FIGS. 3 and 10. The advancing pawl 4% is similarly pivoted at 58 (FIGS. 1, 3 and 8-10) on an operating slide 60 which is reciprocably movable by a reciprocating mechanism between the supporting block 35 (FIG. 7) and rollers till within the limits of adjustable stocks 62 and 6d upstanding from the frame portions 32. It will be appreciated from a consideration of FIGS. 1, 3 and 8 through 10 that such advancing pawl it? is spring-biased in counterclockwise direction so that its operating end passes through the central opening 18 in the second intermediate contact 1d on the continuous strip 16 and engages the left-hand side of such central opening 13. Further, such operating end of the advancing pawl 40 is reciprocable in an operating slot 66 (FIG. 7) provided in the top face of the removable block 46 during operation of the reciprocating mechanism.

As shown particularly in FIG. 1, the strip-advancing mechanism 42 includes the reciprocating mechanism for the operating slide dti and the advancing pawl 3A} carried thereby which reciprocating mechanism comprises conventional linkage, such as a link 68 and a lever 70, for connecting such operating slide 60 to an operating piston 72 of a spring-biased one-way air cylinder 74. This air cylinder 74 may be operated at the desired time by a solehold-actuated air valve (not shown), which air Valve may in turn be actuated in the usual manner by closure of a normally-open switch operated by cam means on the main cam shaft of the base-making machine 26.

When high-pressure air flows into the air cylinder'M the operating slide 60, the advancing pawl 4t and the continuous strip 16 are moved to the left, as viewed in FIGS. 1, 3, and 8 through 10, the aforesaid distance (1 from the position shown in FIG. 1 to the position shown in FIG. 8, thus advancin the leading intermediate contact it onto the movable support it; and into orientation with respect to the transfer head 5t? and movable cutter 52 disposed thereabove and with the head 24 disposed therebeneath at station 1. During the strip-advancing operation the continuous strip 16 rides over the holding pawl 38, depressing such holding pawl slightly. The continuous strip 16 is thus advanced at a predetermined rate and with a stop-and-go motion.

Thereafter or during the latter portion of the strip-advancing operation, as desired, the transfer head 5t} and the movable cutter 52 move downwardly from the position shown in FIGS. 1 and 3 to the position shown in FIG. 8. During this downward movement the transfer head Stl engages and secures by vacuum means such supported oriented leading intermediate contact in and thereafter the movable cutter 52 cooperates with the stationary cutter Me (as a severing means) to sever the now secured and supported oriented leading intermediate contact ftl. After the securing and severing operation, as shown in FIG. 8, a shoulder 76 on the transfer head 5d engages an operating cam '78 afiixed to the movable support 4-3 preparatory for the movement of the movable support 43 out of the path of movement of the transfer head 5%) and the intermediate contact it) carried thereby toward the head 24. As a result of this securing and severing operation, the now severed, secured and supported oriented leading intermediate contact it) remains in the predetermined oriented position without further orientation during the delivery of such severed intermediate contact it! by the transfer head 569 into an octagonal-shaped cavity 81) (FIG. 6) in the head 24.

Transfer head To permit the above-mentioned simultanous vertical downward movement of the transfer head and movable cutter 52, such transfer head 5t) is slidably mounted in a housing 82, as viewed in FIGS. 1, 3 and 8-10, and is coupled to a slide 953 (which carries the movable cutter 52) by a ball 34 confined in a hemi-spherical aperture as in the transfer head 5d and in a longitudinal slot 88 in the v d slide 90. This slide is slidably mounted in the housing 82 between the wall thereof and the transfer head 5%. It will be noted from FIGS. 8-10 that since the center of the ball 84 lies within the slot 38 and that since the ball 84 is pressed by the aperture 36 against the right-hand side wall of the slot 88, the ball 84 is adapted to leave the aperture as when a second hemi-spherical aperture 112 in the wall of housing 82 registers with the aperture 86 (FIG. 9) as hereinafter related.

The drive means (FIG. 1) utilized to cause the downward movement of the transfer head 50, the slide 9% connected thereto and themovable cutter 52- carr-ied by the slide 99 comprises conventional linkage such as a first link 92, a lever 94, a second link 96 and a connecting rod 98, which connecting rod 93 is connected to a cam lever (not shown) driven by a cam on the main cam shaft of the base-making machine 26.

. So that the transfer head 5t may secure the oriented leading intermediate contact 10 which is supported on the movable support 43 (before such leading intermediate contact is severed from the continuous strip 16 and when such transfer head 5t engages the leading intermediate con-tact 18) a vacuum line 1% extends through the side wall of the housing 82 (FIGS. 1, 3 and 8-10) to a vacuum manifold M32 provided in the inner side wall of such housing 8-2. Such vacuum line ltltl then communicates with a plurality of apertures we (only one of which is shown in FIGS. 1, 3 and 8-10) through a port 1% which interconnects the vacuum manifold 102 and the apertures 164 extending to the lower contact face of the transfer head 5t As the transfer head do is moved downwardly from the posit-ion shown in FIGS. 1 and 3 to the position shown in FIG. 8 (but before such transfer head 5t engages the leading intermediate contact Til) the port 106 is exposed to the vacuum manifold W2, thereby applying a vacuum to the apertures 1M and drawing the pronged boss 22a and 22b into the clearance slots 1&5 in the bottom face of the transfer head to maintain orientation before such transfer head applies pressure on the leading intermedietc contact In. Immediately thereafter the movable cutter 52 severs the leading intermediate contact 163 and the transfer head 59 holds the severed intermediate contact it (FIG 8) in oriented position against the movable support 48. i

The transfer head 56, the severed intermediate contact ltl carried thereby and the slide 99 connected thereto then continue downwardly from the position shown in FIG. 8 to the position shown in PEG. 9, where the slide 9% engages a stop 103 (projecting from the housing 82 into a slot 116 in the slide 9t?) thus terminating the downward movement of the slide 9d and the movable cutter 52 carried thereby. When the slide 9%? ceases its downward movement the hemi-spherica-

l apertures

36 and 112 are in registry so that any infinitesimal further downward movement of the transfer head 5t) with respect to the slide 96 forces the ball 84 to move to the right (FEG..9) out of the hemispherical aperture as, across the slot 88 and into the second menu-spherical aperture 112 in the housing 32., thus coupling the slide 9d to the housingtiZ and permitting the continued downward movement of the transfer head 59 and the intermediate contact lit carried thereby to the position shown in FlG. 10.

During the downward movement of the transfer head 5t) and the movable cutter 52 from the posit-ion shown in FIG. 8 to the position shown in FIG. 9, the operating slide 6t) and the advancing pawl 4t? are retracted to the right (the aforesaid distance d so that such advancing pawl ill slides out of engagement with the now leading intermediate contact If on the continuous strip 16 and into engagement with the now second intermediate contact ltl. Because of the engagement of the holding pawl 338 with the continuous strip 116, the continuous strip 16 remains stationary with respect to the supporting block 7 36 during this retracting movement of the operating slide 60 and the advancing pawl it).

Simultaneously, as the transfer head fill moves from the position shown in FIG. 8 to the position shown in FIG. 9, such transfer head 55} begins to move the movable support 48 away from its downward path of movement toward the head 24, as now described.

Movable support This movable support 48 and the operating cam 78 associated therewith are affixed to a shaft 114 (FIGS. 1, 3 and 81()) journalled in a bracket 116 depending from the lower portions of the housing 32,. Such movable support 43 and the operating cam 73 are biased upwardly in counterclockwise direction to the normal contact- -suppcrting position of the movable support 123 by a spring 118 (FIGS, 1 and 3) as determined and limited by an adjustable stop 12d projecting from the operating cam 75 and engaging the bracket 11%.

It will be apparent from a consideration of FIGS. 8 through 10 that as the transfer head moves downwardly from the position shown in PEG. 8 to the position shown in FIG. 10, the shoulder 76 on such transfer head 5d exerts a downward force on the operating cam 78 to move both the operating cam '78 and the movable support 48 in clockwise direction (against the action of the spring 118) out of the path of downward movement of the transfer head and the intermediate contact 16' carried thereby toward the octagonal-shaped cavity 89 in the head 24.

To provide means for releasing the intermediate contact 1i) from the transfer head 8i? when it is deposited in the octagonal-shaped cavity St), the port 1% in the transfer head 5% moves out of communication with the vacuum manifold 102 (FIGS. 8-10) and into communication with a high-pressure air line 122 extending through the side wall of the housing 32. This highpressure air causes attendant elimination of the vacuum within the port 1% and permits the intermediate contact to remain in the octagonal-shaped cavity 8t?! when the transfer head 59 is retracted from its position shown in FIG. 10 to the position shown in FIGS. 1 and 3. Because of the similar octagonal-shape of both the intermediate contact lit and the cavity 80, such contact 10 remains locked in the predetermined oriented position with the lead-wire boss 2211 on the left, as viewed in FIGS. 1 and 3, without further orientation.

When the transfer head 5t? arrives at the intermediate position shown in FIG. 9 during this retracting movement; the hemi-spherical aperture 86 again moves into registry with the hemi-spherical aperture 112, as shown in FIGS. 1 and 3. Simultaneously therewith a pin 124, (projecting from the slide 96 into a longitudinal slot 126 in the right-hand side wall of the transfer head Ed) is engaged by the bottom of such slot 126 so that thereafter both the slide 9d and the transfer head Stl are coupled together. Any further infinitesimal upward movement of the now coupled slide 90 and the transfer head 51) forces the ball $54 to move to the left across the slot 88 and into the herni-spherical aperture 86 to uncouple the slide 941 from the housing 82, thus permitting the slide 90 and the transfer head 5d to thereafter retract upwardly together to the starting position shown in FIGS, 1 and 3, preparatory for the next contact-feeding operation and for the indexing of the now loaded head 24 out of station 1 (FIG. 1).

Thereafter the head 24- indexes to station 4 (FIG. 11) where a center contact 128 (FIG. 12) is fed into an eyelet pocket 130 (FIG. 6) in the head 24 and thence to station 8 where a shell 132 (FIG. 12) is positioned in a shell-receiving aperture 134 (FlG. 6) in the head 24. At station 14 a predetermined gob of molten glass is fed to the head 24 and molded at stations and 16 into the glass insulator 2d shown in FIG. 12.

S A pairof plungers (not shown) are utilized at station 20 to maintain the openings through the hollow lead- Wire pronged boss 22:: and center contact so that upon completion of the base 12, lead wires (not shown) may be passed therethrough.

In the conventional manner the finished base 12 is then assembled to an exhausted Three-Lite incandescent lamp 14 to provide the finished lamp shown in FIG. 12.

it will be recognized by those skilled in the art that the objects of the present invention have been achieved by providing an improved apparatus for feeding articles in a predetermined oriented position to an article-fabricating machine. Such improved feeding apparatus will operate efliciently at a high production rate and is adapted to receive a continuous strip of articles disposed in a predetermined oriented position thereby eliminating the need of conventional complicated and expensive articleorienting means heretofore employed.

Specifically, the utilization of a continuous strip of octagonal-shaped intermediate contacts provides a 30% reduction in the scrap metal in the original strip by permitting the intermediate contacts to be punched from a strip of metal having the same width as the intermediate contact and by eliminating any web between adjacent unched intermediate contacts. This elimination of the web permits the improved feeding apparatus to sever the intermediate contacts from the continuous strip with a single cut. Further, the use of the continuous strip of intermediate contacts in the improved feeding apparatus permits the use of a positive feeding means thereby resulting in higher equipment efiiciency and a higher production rate. Such improved feeding apparatus receives the intermediate contact in a predetermined oriented position and transfers individual intermediate contacts to the bottom die of a base-making machine where such intermediate contact, because of its octagonal-shaped will remain locked in the oriented position.

While in accordance with the patent statutes one best known embodiment of the present invention has been illustrated and described in detail, it is to be particularly understood that the invention is not limited thereto or thereby.
