MEANS FOR TRANSFERRING GLASS TO MOLIDS.

Application filed February To all whom it may concern.

Be it known that T, LEONARD D. SOUBIERs a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Tmprovements in Means for Transferring Glass to Molds, of which the following is a specification.

My invention relates to apparatus for to receiving glass from a molten supply, forming it into gobs or charges, and transferring them to molds. An object of the invention is to provide improved means for feeding a number of machines, such as glass pressing or blowing machines, with gobs from the same furnace outlet or source of supply.

Tn its preferred form the invention comprises two transfer cups mounted on a reciprocating carrier by which they are brought alternately beneath an outlet opening of a furnace or container from which the molten glass is supplied. While the glass is flowing into one cup to form a gob, the other cup is over the mold of one machine and discharges thereinto. The carrier is then shifted to bring thecupwhich has just been discharged into glass receiving position, the other cup at the same time being moved with its charge into position to discharge into the mold of a second machine.

Other features and advantages of the in vention will appear hereinafter.

In the accompanying drawings:

Figure 1 is a part sectional elevation of the apparatus and of the glass forming machines.

Figure 2 is a part sectional plan view of the same, the machines. being shown diagrammatically.

Figure 3 is a plan view on a larger scale of the transfer cups and their carriage.

Figure 4: is. a sectional elevation at the line 44 on Figure 3. Y

The molten glass flows through an out- 45 let orifice 11 in the bottom of a boot or extension 12 of the refining tank, into transfer cups A and B, which are brought alter nately into receiving position beneath the outlet opening. The cups are carried on a 50 carriage 13 which ismounted to reciprocate on tracks 14; 7 These tracks are supported on brackets 15 attached to and depending from the framework 16 whichsupports the boot 12. The carriage 13 with the transfer 12, 1920. Serial No. 358,028.

cups thereon is reciprocated by means of a cam 17 fixed to a continuously rotating vertical shaft 18. An operating lever 19, mounted to rock on a shaft 20, has a forked end to straddle a roll 22 attached to the carriage 13. An arm 23 on said lever carries a cam roll 24 which runs on the cam 17. The lever 19 may be held in contact with its cam by a spring 25.

The parts are so arranged and proportioned that when the transfer cup A is receiving its charge, the cup B is in discharging position over a mold on the glass forming machine 0, and when the cup B is in charge receiving position the cup A- is in discharging position over a mold of the machine D. Each of the machines C and D may comprise an annular series of sets of molds which are brought successively into charge receiving position, either by an intermittent or continuous rotation of the machine. Each set of molds, as here shown, comprises an inverted blank mold 26, a neck mold 27 in register therewith, and a finishingmold 28. When the blank mold has received its charge it is opened, leaving the bare blank supported in and projecting upward from the neck mold. rying the neck mold is then rotated about a horizontal axis to swing the bare blank downward into the finishing mold 28 which A head 29 carthen closes around the blank and the latter is blown to its finished form.

Each of the transfer cups A and B comprises a section 30 stationary with respect to the carriage 13 and a section 31 slidable to and from the fixed section, thereby permitting the sections to be separated for discharging the gob. The sections are normally held together by means of springs 32 mounted on rods 33 attached to the section v 31. The rods 33 extend through openings in lugs 45 on the mold section 30. The lugset are provided with studs 46 which seat In corresponding recesses in the carriage so that the mold is removable by simply lift- ,ing it from the carriage. As a cup moves to discharging position the section 31 strikes a stop 34 and arrests its movement while the section 30 continues; to move with the carriage, thereby separating the cup sections when directly over the mold 26 so that the gob of glass is dropped into the mold. While the cup B is in discharging position the cup A is directly beneath the flow opening and receiving its charge. When a suflicient amount of glasshas flowed into the cup A to form a mold charge, a cutter'35 operates to sever the charge from the oncoming stream and support the latter until the cup B is brought beneath the flow. The blade 35 is carried on an" arm 36 of a bell crank mounted to rock on the shaft 20, and the other arm 37 of the bell crank carries a cam roll 38 which runs on a cam 39 fixed to the shaft 18. "F

The machines C and D are geared to run in synchronism so that the molds of one machine are brought into charge receiving position in alternation with those of the other machine. The shaft 18 is also geared to run in synchronism with the mold carriages and makes one half of a complete rotation for each gob discharge-d, or in other words, both machines receive a charge of glass during each complete rotation of the shaft. It will be noted that the cam 39 is double so that the knife is given a cutting stroke during each half rotation of the shaft 18.

The operation may be summarized as follows:

With the parts in the position shown in full lines in Figures 1 and 2, the-glass is flowing into the transfer cup A and the cup B has just opened and dropped its gob into themold 26. The rotating cam 17 now operates through the lever 19 to shift the carriage 13 to the right, thereby carrying the cup B to receiving position beneath the flow and carrying the cup A with its charge to discharging position over a mold of the machine D. The knife 35 is operated by its cam 39 to sever the glass substantially as the transfer cups commence their travel. The knife co-operates with a stationary shearing plate 41 which together with the knife forms a shallow receptacle or support for the glass during the shifting of the transfer cups. It is only necessary to thus support the glass for a brief interval, as the cam 17 is designed to impart a rapid movement to the carriage 13, the latter traversing its full length of travel while the mold carriage is moving through a small angle. Thus thecup A is moved from its receiving position to the discharging position A (Fig. 2) while a mold is carried from position 26 to its charge receiving position at A,

Variations may be resorted to within the spirit and scope of my invention. It will be understood that the invention is adapted in general for use with any type of machine in which the charges of glass may be dropped into the mold, the particular form of machine 0 and D- being shown merely by way of example.

What l[ claim is:

1. In an apparatus for transferring charges of molten glass, the combination of a track, a carriage, means to reciprocate the carriage on said track, receptacles mounted on said carriage and each comprising separable sections, one of which is 'movable toward and from the other on the carriage, a stop for each receptacle arranged to engage the movable section of the receptacle as it approaches its limit of travel in one direction and thereby separate the sections of the receptacle.

2.- In apparatus for transferring charges of molten glass, the combination of a track, a carriage mounted to reciprocate thereon, transfer cups on said carriage, each comp-rising an inner and an outer section relatively movable lengthwise of the carriagefor opening and closing the cups, and stops at the end of said track in position to arrest the inner section of each cup as the latter approaches the limit of itsmovement with the carriage and thereby separate the cup sections.

3. A glass transfer device comprising a reciprocable carriage, a sectional transfer cup on said carriage and reciprocable therewith from a receivlng position to a discharg ing position, the upper end of said cup being open to receive glass, and the section of the cup on the side towards the receiving position being slidable away from the other section, resilient means normally holding the sections together, and a stop for arresting the slidable section as it approaches discharge position and thereby opening the cup.
