UNITED STATES. PATENT OFFICE;

MICHAEL J. OWENS,-OF TOLEDO, 'omo, As'snmoa TO THE roLnnocLAss comm, or TOLEDO, 01110, a CORPORATION or 01110;

- LEEB AND BEER-CHARGING MECHANISM.

To all whom it concern:

' a citizen of the United States of America,

residing-at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Leers and Leer-Charging Mechanism, of which the following is a s ecification, reference being had therein to t e accompanying drawings.

This invention relates to new and use ul improvements in leers and leer-charging mechanism, 'and consists, first, in the construction of the leer whereby it may be automatically charged with ware; second, providing the leer carrier with holders so that it will hold the. bottles, these holders serving to prevent the tipping of'narrow-bottomed bottles and also permit the charging of the leer'sectio'ns by bottles which may he delivered into the holders'directly fromthe glass-forming nxachine; and third, in the construction of the carrier so that the same may be charged, fed through" the leer, re(

turned to charging position, and re-charged, as a continuous operation.

In the construction shown, all of these operations are automatic except the transfer of the carrier sections from the discharge end of the leer to the .return mechanism; and the devices consist in the construction, arrangement and combination of the various parts, all hereinafter more fully set.

forth and particularly pointed out in the claims In the drawings: Figure 1 is a plan view, partly in section, showing the leer,'the return mechanism, the intermediate transfer mechanism, and diagrammatically illustrating the position of the glass forming machine and fire-finishing machine; Fig. 2

is a vertical section through the intermediate transfer carrier; Fig. '3 is a side elevation of a portion of that carrier illustrative I of the construction of the feed-pawl therefor; Fig. 4 is j asection through a portion of the carrier and the fire-finisher adjacent to the leer; 5 is a longitudinal section through the return carrier; is a vertical section on line H of Fig. 1; Fig. 7' is a side elevation 'ofapaontion of the return carrier; Fig. 8 is a p of a portion of the return carrier illustrating the construction of the feed-trigger; Fig. 9 is a vertical section through the actuating mechanism for the feed device or pusher for the leer Specification of Letters Patent.

in, as plainly shown in Fig.

'15 upo sections; Fig. 10 is an enlar ed -section Patented Nov.. 17:191 4. Application med January 1a, 1909. Serial No. 472,937.

through the clutch pin of the eeddevic and Fig. 11 is an elevation of the clutch;

' Y '1 is the leer. In the side of each side wall is a recessed track 2 on which-runs rollers 3 at the'ends of the as will be seen ,in Fig. 6. here are two.

of these rollers at each end so as to support 1 v an-v sections 4-,

metal of substantially inverted U-shape in cross-section, as shown in Fig. 2, having formed in the connectingor horizontal portiona longitudinal series of tapering sock:

ets 5. These sockets as shown-are 'of a shape-fitting the tapering shoulder of -the battle when the bottle is in an inverted position, or neck downward, the bottle. being numbered 6. Itis,obvious that if all the sockets be filled in a single carrier sectionthere will be a row A ereof suspended there- The carrier sections are intended, with the construction shown, to be fed longitudinally across the end of the leer, as shownat the-left-hand of Fig. 1. This is prefers.

ably done automatically by' mechanism' to 1 be hereinafter described. When a carrier section is thus fed in, it strikes the end of the push-rod 7, sliding to the guides in the side-wall of the leer and in the path of a communicating carrier-section. The push-rod 7 is connected to a bell-crank 8 which in turn connects to the bell-crank 9 which isconnected to the rod 10, havingat its end a block 11; these shown in Figs. 1 and 9. 12 is a motor driving the pinion 13 meshing with the gear-wheel 14 which eonstantl revolves. The wheel 14 is loose onthe'sha n which is secured, the wheel' -16.- On the wheel 16 .is a clutch-pin 17sliding in vertical guides therein.

, 18 is a spring acting to ,push 17 downward whenever the same is released by parts beingfully 40 is a rod secured to the end of the bell- When the leer section strikes the head of the push-rod 7 through the connection as, shown, it will withdraw the block 11 from the notch 19, the engagement therein of which has held the pin 17 out of engagement with the lugs 23 on the wheel 14. As soon as released, the spring 18 will force the pin 17 into the path of these blocks and the wheel 17 and the shaft 15 will be given a single revolution. During this single revo lution .of the shaft 15, a crank 24 at the upper end thereof will move the pusher-head 25 forward, impinging against the last section fed in, thus pushing that carrier section, and any that may be ahead of it, along the guide-way 2 the width of one carriersection, and it will then be withdrawn soas to leave a place for an incoming carrier section.- At the outermost point'of travel of the pusher 25 the block 11 having been projected by the spring 22 back into the path of the pin 17, the incline 20 and the incline on the block 11 will engage and lift the pin 17 out of the path of the lugs 23 and thus stop the rotation of the shaft 15. At that end of the pusher 25 beside which the pans enter, I cut away the portion 27 so that a partial entering of a new pan durin the pushin operation will not be interfered with. Vhen the leer sections completely fill th 'e leer and the ware is annealed at the delivery end thereof, the operator in the packing-room takes out the end-pan with its contents, discharges the bottles therefrom for packing and delivers the carrier section by any suitable means upon the carrier 30 which is shown as arranged parallel with the leer lbut separated therefrom. This carrier is rovided with tracks 31 upon which the rol ers 2 may run in the return of the leer sections. The leer sections are pushed along on the carrier by means of the triggers 32 (shown in detail in Figs. 7 and 8). These triggers are shown as pivoted upon the pivot pins 33 of the chain, connected at the lower ends to a spring 34 which may be connected to the adjoining pin 33. Thekprings tend normally. tohold the triggers in upright position against a stop 35, and as they travel they strike the leer section placed upon the track 31 and move it along until that section strikes the accumulated sections or the stop 36 at the end of the carrier. As soon as this occurs the triggers turn on their pivots,expanding the springs 34, and thus pass along beneath the. accumulated sections without moving the same. From this carrier 30 the leer sections are automatica ly fed back to the leer, which may be done by the following mechanism: 1

crank 41 which is intermittently rockcd from any suitable source of power. On this rod 40 is a pivoted pawl 42 adapted to engage into the sockets in the leer sections, as

plainly shown in Fig. 3. This rod 40 is pushed back so as to engage in a new socket and then pulled forward a distance. between the adjoining sockets,-thus feeding the leer sections longitudinally out of the return carrier and longitudinallytoward the leer entrance that distance' -I have indicated by the circle 43 a glassshaping machine. This particular detail design of my leer is designed to be used in connection with the machine shown in my previous PatentNo. 766,768, dated August 2, 1904; and the circle indicates substantially the path which the molds take in passing from the tank where the glass is gathered, to the blowing stage, discharging point, and back to the gathering point. The discharge point of the machine is substantially over the path of travel which the leer sections take in traveling from the return carrier to the leer, and the bottles made in the machine when discharged may fall into a funnel 44 which will direct them, mouth downward, successively into the sockets, as shown at Fig. 4. In traveling from the return carrier to the leer, the leer sections travel on a guideway 45 having rollers 46 upon which the lower edges of the sections run, and

guides 47 to prevent side-displacement.

Between the pointat which the bottles enter the leer sections and the leer, I preferably arrange a fire-finisher 50 to fire-finish the neck of the bottle and take ofi any sharp edges that may be formed by the machines in the process of manufacture. This consists of simply a small furnace 48 having apertures 49 through which heat can be directed upon the necks of thefbottles, as the same approach the leer. This furnace may be provided with gas burners, as is usual, or may be of any of the known or usual constructions for the purpose.

The device being thus constructed, the operation as a whole is as follows: A glassshaping machine, if used to manufacture bottles, drops out a bottle during its rotation at the same point each time, and this bottle falls into the funnel 44, and is directed, neck downward, into the socket 5 in the leer section which is beneath the mouth of the funnel. Before another bottle is delivered into the leer section thebell crank 41 which is preferably driven from some 'part of the glass-shaping machine, suitably timed in connection therewith, is rocked, and its pawl 42 engages the socket 5 of one of the leer, sections and shoves the entire line of leer sections which form the transverse carrier one step forward. This moves the bottle already delivered beyond. the funnel 44 and brings a new socket in position t6 receive the bottle. i

The successive feed forward by the bell crank 41 and the pawl 42 will move the leer section over the fire finisher where the ping it over, and thus delivering them into heat will be caused to impin e upon the neck of the bottle to fire-finish t e same, and then move the bottles in that section into the leer, as shown at the left-hand of Fig. 1. i When the section is pushed into the leer to the limit of its motion, it operates the rod 7 and through the connection described, the pusher 25 ushes this section, with those which may he in front of it, forward into the leer and withdraws to permit the next section to come in- The furnace is provided with suitable heating devices (not shown) for annealing. At the delivery end of the leer, the operator takes out the leer sections, discharges the bottles therefrom, which can be done by tipan u right position, and then feeds, by any suita le means, or carries, the section to the return carrier where it is returned again to the feeding point, as above described. In this-way it will be seen that the bottle is fire-finished. and annealed, is automatically taken from the machine and carried through these operations; and that this 0 eration may be continuous Without the emp oyment or the necessity of any labor as ordinarily employed to carry the material to the leer. It will also be seen that the device is ex tremely simple and can be,manufact'ured at an expense not exceeding the present cost of the leer alone.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a charging stat1on for glassware com rising a chute in which the ware is fed, 0 a leer carrier element comprising detached movable pans constructed to receive a series of formed glassware, means for moving the pans beneath the said chute to receive the ware and for presenting the pans to a leer feeding mechanism and a leer feeding mechanism for feeding the pans through the leer.

2. The combination with a charging chute, of a leer tunnel, aseries of leer ans, means for moving the pans'outside t e leer beneath the charging chute step by step and into the leer, means on the leer pans for holding articles in a row, and means for moving the alined pans laterally through the leer.

3. The combination with a leer, of a series of leer pans, each pan havin a row of ware-holding sockets, of means or feeding the pans to a ware-charging station and endwlse therefrom into the leer, and means for lfeeding the pans side by side through the v eer.

.automatically deliverin a series of separate ware-carrying pans,

means for moving the pans through a leer tunnel, and a feed carrier for feeding the pans endwise into the leer in position to be acted upon b the said pan moving means.

7. The com ination with a leer tunnel, detachable ware supporting devices therefor, means for feeding the devices into thetunnel, means for feeding the'devices through the tunnel, and means operated by the incoming ware su porting device for causing the said tunnel eeding device to o erate.

9. The combination with the leer tunnel, of a series of ware-supporting devices therein and means for automatically filling the devices with ware outside the tunnel, a carrier for delivering the filled ware supporting devices intothe leer, and means for moving the filled devices through the leer chamber.

10.
