FEEDING DEVIGE FOR LEERS.

Lit-@68 0? Application filed .iannary 21, 1999.

l eediug Devices for lieers, of which the following is a specification,- refei'ence being had therein to the accompanying drawings.

This invention relates to new and useful improvements in feeding devices for leers, and consists in the construction of a feed carrier arranged above the plane of travel of the leencarrier. and which will feed the articles over the leer-carrier and then drop theni in rows thereon. The leer-carrier is pro vided with sockets into which the articles are directed.

The invention further consists in the construction and arrangement in combination of the various parts, all more fully hereinafter described and particularly pointed out in the claims,

In the drawings: Figure 1 isa vertical section transversely through the leer, showing an elevation of the feed-carrier and its driving mechanism, and also showing, partly in section, a fire-finishing furnace over -Which the artici s travel; Fig. 2 is a plan view of one sect-ion'of the carriei chain; Fig. 3 is a section on line of Fig. 2; Fig. e is a horizontal section through the leer showing the feed carrier in plan and partly broken away; Fig. 5 is a vertical section through that portion of the feedcarrier in the furnace and illustrating the actuating devices for opening the holders to discharge the bottles; and Fig. 6 is a longitudinal section through a portion of the leenoarrier illustrating the construction of the holders therein.

1 represents the leer-tunnel formed of the usual brick-work, having therein a carrier Which moves from one end to the other.

I have shown the carrier as consisting of an endless chain 2 running on the sproclreh Wheels 3 and having secured to the links the transverse carrier pans or sections 4: pro vided With a series of downWardly-tanering sockets or cups 5; these sockets or on s being arranged in transverse rows, as clear y appears in Fig. l. The sections may be supported at their ends by the Wheels 6 running on the "tracks 7 at each side of the tnnnelt s ecification of Letters latent.

frame, the frame being: an open frame andsubstantially rectangular. Throu 'h the lugs 12 extend the pivot pins 13, and pivot pins are pivoted sections M and 15 of the cups which form the holders, the pivotal connections made between the pins and lugs 16 projecting laterally from the topof each cup section.

integral with the cup section 15 is the leverl? having a Weight 18 at its outer end, and its inner end is curved so as to extend around the side oi the cup section and project out beside the other section. At its end it is provided with aslot in which is engaged a pin 19 on the section 14.

The open meeting edges of the two can sections, ivhich are substantially cylindr" cal inv cross-section-when used for bot (the construction here shown), are provided With curved faces 20. This construction such that the action of the Weight normally tends to hold the cup sections together, bi. if the Weight is lifted the two sections n turn on these curved faces 20 and open the lower end of the holder and permit the articles to fall therefrom by gravity.

For the purpose of lifting the Weights at the desired time, I provide on each weig, a downwardlyextcnding lug 21. Extending across the leer, just below'the path of travel of the lugs 21, is a rock-shaft 22 (Figs. and 5), and on this rock-shaft is an arm 25 projecting beneath all the lugs QIWhich on these of the bottles as falling into a funnel. 25, the

' leer-carrier.

. adapted to discharge from which is directly above one of the holders in the feed-carrier, so that the bottle will fall therein.

The feed-carrier and the leer-carrier may be driven from the motor which drives the glass-blowing machine referred to, or they may be timed to operate in connection'therewith.

I have shown. a shaft 26 projecting from the base 27, which is intended to be the base of the said blowing-machine and which may be driven from the motor thereon. This shaft at its end has a crank 28 to which is connected the pitman 29 guided in the guide 30 at its lower end and having a pawl 31 engage with the teeth on the ratchet-wheel. connected to the shaft 33 to which is secured the sprocket-wheel 10 of the feed-carrier. It is obvious that the reciprocations of the pitman 29 will feed forward the feed-carrier one step for each revolution of the crank 28, and being timed with the blowing machine so that immedi ately after a bottle is dropped therein the carrier will feed forward so as to bring a fresh holder of the cup beneath the spout of the hopper 25. 1

On the shaft 26 is a pinion meshing with the gear-wheel 36 on a stub-shaft -from the base 27, and this gear-wheel carries a pin or finger 37 adapted to strike the arm 38 on the rock-shaft 22; so that in each revolution of-the gear-wheel 3(3'the shaft 22 will be rocked and will then fall back again by gravity to its initial position, as soon as the finger 37 has passed the arm 38.

I have shown a fire-finishing furnace 40 arranged between the reeeivingpoint of the feed-carrier and the leer, so that the bottles in passing over this furnace have their necks fire-finished before entering the leer.

The drive-chains of the leer-carrier as above described are driven by the sprocketwheels 3 which are secured to the shafts a5; and at one end of the leer this shaft extends through the machine, and any suitable intermittent driving mechanism may be applied thereto so as to feed the leer-carrier forward while the feed-carrier is bringing in a new row of bottles and thento stop the leer-' carrier while the cups are opened to dis charge the bottles from the feed-carrier and permit them to drop into the sockets in the I have shown at a9 a clutch mechanism for this purpose, but, as it forms no part of my invention, and any suitable be used for this purintermittent drive may to describe pose, I do not deem it necessary or explain the same.

The parts being thus constructed their operation is as follows: The bottle machine is run at constant speed and usually delivers a bottle about every four seconds. As the bottles are thus delivered at uniiiorm in tervals, it is a simple matter to time the mechanism for carrying out the rest of the operation. As soon as the bottle has dropped I into the holder in the "teed-carrier, that carrier is moved forward one link by the pawl 31 and the ratchet-wheel 32 and stopped with another empty holder beneath the spout of the funnel 125. As the bottles thus travel from the charging point to the leer in a step-by-step in \'eine11t,.they pass over the fire-finishing i'urnace l6 and their necks are lire-tinished-as, in the construction shown, the necks are downward and project below the carrier-holders. They next pass into the leer and, when a, complete row thereof is arranged in the leer above the leer-carrier, each bottle will be above one of the sockets in the transverse row of sockets'in the said leer-carrier. At this moment the shaft 22 is rocked, the arm 23 lifted and impinged against all of the lugs 21 above the arm 23, opening the holders in the feed-carrier which are within the leer and allowing the bottles to drop therefrom into the sockets 5 in the leer-carrier sections. The feed'carrier then travels over the sprocket-wheel at the other end and returns to be re-eharged, passing in its return-trip beneath the leer, as shown in Fig. 1..

By the construction described it will be observed that the ware is deposited directly from the feed carrier onto the leer carrier as distinguished from the indirect or these structures wherein the ware is first collected on a table or platform and from there shoved or moved onto a leer carrier. It is therefore to be understood that the term direct employed in. certain claims has reference to this feature as distinguished from feed carrier onto the leer carrier.

Having thus described my invention, What I claim as new and desire to secure by Leo ters Patent is:

1. The combination with a leer, of its car rier having sockets to "retain and support the articles thereon, and a feed device for feeding the articles transversely into the leer and depositing them in the sockets.
