To all/whom t may concern.'

Be it known that I, CHARLES E. BLUE, of Wheeling, Ohio county, and State of West Virginia, have invented a new and useful Improvement in Machines for Gathering Glass, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming Figure 1 is a vertical'section of one form of apparatus embodying my invention; Fig. 2 is a plan view of the same partly broken away; and Fig. 3 is an end elevation of a portion of the gearing.

My invention has relation to machines-for gathering glass, and is designed to provide a machine whereby the mechanical gathering of glass and its delivery to molds may be accomplished with accuracy and certainty.

The precise nature 'of my invention will be best understoodl by reference to the accomone embodiment thereof, and which will now be described, it being premised, how ever, that various changes may be made therein by' those skilled vin the art, without departing from the spirit and-scope of my In these drawings, the numeral 2 designates a glass-melting tank or vessel, having an overhanging portion or dog-house 3, formed with a discharge vopening 4 in its bottom wall. The discharge through this opening is controlled by a vertically movable stopper 5, which may be actuated in any as by the bell crank and

operating lever'connections

6, 7, 8, 9 and 10.

That portion of the discharge opening 4 which is nearest the interior of the tank is made lof smallerfdiameter than the exit portion thereof,"'and the Venlarged portion of this opening is extended through a discharging block 11, of refractory material which is vsecured to the under side o-f the dog house and which is provided with a water jacket 12, through which water may be circulated in any suitable manner. Secured to the lower end of the discharge block 1l by a hinge pin 13, or other suitable connection, is, a discharging ring 14, which is normally held in position by a removable pin or bolt 15.

16 is a rotary table or carrier which is arranged to turn on a central stationary post measuring vessels or receptacles 18, so arrangedl that when the table is rotated,these A receptacles will be brought in succession beneath the orifice of the discharge ring 1.4.

These receptacles preferably have a narrow top opening dared downwardly andclosed lat its lower end by a cup-shapedvalve 19,

which is hinged at 20, and. which is operated by suitable means so that it'can be opened after the receptacle has received its dis-- v charge of glass and has beenmcved into discharge position over a mold 21, into which f` the glass is to be delivered. v y l As-a convenient means for automatically operating the valves 19, I provide each of them with a jointed operating rod 22, provided with a spring 23, which tends to pull the valve open. The inner end of the rod` carries a wheel 24, which travels in cont-act with a statlona'rv cam surface 25, which extends around the central post 17. This cam surface at a point opposite the position of the mold 21, has a recess 26, into which the rod is forced by the spring 23, when the'discharging position is reached, thus permitting thespring to, pull the valve-open, as

shown in full lines at the right-hand' side of Fig. 1, to thereby discharge the glass from the measuring vessel-into the mold below.

The opening at the top of each of the receptacles 18y ispreferably madeoval or elongated in the direction of the rotation-I of the table.

The support 27 for the` table, together with the post-'17, is vertically adjustable to the desired height, preferably by means of a rack 28, on the support 27, which is engaged-by a pinion 29, operated byf a pawl( and ratchet 30, the ratchet being carried by. a lever 31.

The table may be rotated by any suitable means. In the drawings, I' have shownit- 'as provided with a ,circular rack 32, whichis engaged by a spur wheel 33, driven through y l furnace. For the purpose ofvstopping. theV table positively at proper positi` v11sanyy suitable braking device may be employed, such as the spring-actuated dog 36, which is mounted on the frame of the table and is arranged to engage notches 37 on the central post 17.

The operation is as follows: By depress-` ing the hand lever 10, which controls the stopper 5, glass is allowed to start from the tank or melting furnace and flows in a small hot stream through the contracted portion of the discharge opening 1,`and,thence into the enlarged water-jacketed portion of said opening. In flowing through this enlarged portion of the discharge opening, the glass is cooled -to such an extent that it will pass therethrough by a sliding action rather than by a How. -The purpose of this is three-fold. First, it enables the operation to be started with glass suiiiciently hot to How freely through the small entrance portion of the discharge orifice; second, it permits the glass to chill somewhat before it is discharged, so that by the time it gets to the mold-for use, it will not be so hot as tostick to the surfaces with which it comes in contact; and third, it enables the cutting or severing to occur with a column of glass at each operation instead of a stream, so that an absolutely fixed quantity can 4be delivered out each time by means of the measuring vessel or receptacle. As each measuring vessel or receptacle is filled, the table or carrier is revolved sutiiciently to bring another measuring vessel or receptacle into position, the solid plane 'portion of the table between the measuring vessels or receptacles acting to close the opening in the ring 14, until such time as the measuring vessels or receptacles are brought into proper relation to such opening. After each measuring vessel or receptacle is filled, it is carried around to the mold 21, by the successive rotations of the carrier and is discharged into the mold by the openin of its bottom valve 19in ,the manner be ore described.

The machine herein described accomplishes with accuracy and certainty the mechanical measuring of the glass delivered to the mold, thequantity of glass delivered to each mold being the same in all cases.

I do, not limit myself to the use of the particular form of movable table or carrier which I have herein shown and described, as my invention is independent thereof, and any suitable 'carrier may be employed for transferring the glass delivered" from the tank or furnace to the molds. Various other changes may also be made.
