Toall'whomz'tmcy comm:

Be it knownthat I, KARL E. Parana, a citizen of the United States, residing. at Hartford, in the coun :of Hartford. aild State of Connecticut, ve invented new anduseful Improvements in Methods and .Machines for Feeding Molten Glass, of

which the following is a specification.

This invention relates to the art of gathering separate masses of molten glass insuitable condition for subsequent shaping operations.

The objectof the present invention is to provide a method'and apparatus for feeding masses or gathers of molten glass, uniform in size. consistency and temperature, and in timed relation, to molds or other shaping devices.

In the embodiment of the invention illus trated herein this object is attained by flowing the viscous glass from the furnace outlet against a gathering head which is rotated to distribute the accumulating glass around the head. When the accumulation is sufii cient for the purpose the head is slowed or stopped to permit the glass to shed-down5 wardly'by gravity and forma depending ball "which is then severed and conducted away. These operations take place in a heated chamber in order to keep the glass in properworking condition and the gathering and severing implements arecooled so that they will best perform'their functions.

The gathering head is mounted for axial movement toward and from the furnace out? let," to regulate the flow of glass to the head,

and when desired, to arrest the flow more or less completely while a gather is being shed or discharged from the. head.

4 In the views Figure 1 shows a side leva-' tion of the active mechanisms and a section of the wall of the furnace and heating charm ber. Fig. 2 is a section on the plane indi-' cated by the dotted line 22 on Fig. 1 showing the front wall of the heating chamber.

Fig. 8 is a section on the plane indicated by the dotted line 3-3 on Fig. 1 showing the adjustable means for periodically rotating the gathering head. -Fig.' 4: illustrates-the distribution of the gather around the head.

The furnace 3 indicated in the views has a discharge outlet or spent 1', and an adjuso able gate 2 for regulating the flow of glam to the outlet. The spout projects into a chamber 4- having walls of refractory mate namon annmcnmnroa rnnnme onrnn crass.

Y- rial. In thev form shown the wall is made of two sections 5 that are hung upon the upper edge of the top wall 6 so that they may be drawn apart and separated to permit access to the chamber and the withdrawal of the gathering head. Suitable gas burners 8 are arranged to blow gas flames thror'igh apertures into the chamber.

Specification of Letters Patent. Patented July 31, 191 7. I Application Mme-4,1916. semi 110. 134.826. i

The gathering head 9 of refractory matei 10 that is provided with a pulley or friction rial is attached to the end of a tubular shaft roll 11. This shaft is mounted so that it will rotate in a sleeve 12 which is slidably held in a bearing 13 at the top of the frame 14. The gathering head shown is shaped like a turnip or an acorrf, and is located in the hot chamber 4, with its apex "and the axial line of the supporting shaft pointing toward and into the discharge spout 1. This head and its shaft are preferably tubular in order that air may be circulated through them to prevent thehead from becoming overheated. For rotating the head at the proper time a pulley 11 onthe shaft 10 is arranged'to be engaged by the sectional driving disks 15. A portion of the periphery of each section of the driving disk is cut away or relieved,

and these sectio s are adjustably secured together so that there'lieved portion of the disk may be 'lengthened and shortened according to the time it is desired to arrest the rotations of the head: When the periphery of the disk engages the pulley the head is rotated, and when the relieved portion of the disk reaches the-head it remains stationary.

The head 9 is adjusted longitudinally toward and from the spout by means of the nuts 16 which turn on threaded portions of extension 17 that projects into a cam groove in the cam 18. This cam groove is cut to give the desired longitudinal movement to the shaft and gathering head and it is mounted on the shaft 19 on which the sectional head rotating disk is mounted and which is provided with a driving gear 20. As the molten glass flows through the disthe sleeve 12 and the bearing 13 has an charge outlet from the furnace onto the head it is flared outwardly and distributed around the head,.upon which a mass is thus accumulated. As this takes place the head is preferably retracted by the cam 18 from the outlet to facilitate and regulate the flow of glass. After a sufficient quantity has been gathered the rotation of the head ceases and it is also preferably moved endwise, closer to the outlet, to diminish or check further flow from thedischarge outlet. With the head nearly or quite stationary the glass sags or is shed from the head and forms a depending ball, which is then out off by shear blades 21 and 25}. The

lower blade 21 is fastened to a sleeve 22 which is provided with .a' bevel gear 23, and

sprayer.

in any convenient way from, or in connection with, the glass shapmgmachme with the upper blade 24 is fastened to a shaft 25 that extends through the sleeve 22, and

is provided, with a bevel gear '26. Engag ing these gears so the shears revolveoppositely is a bevel gear- 27 on a shaft 28 provided with a gear 29 in mesh with the gear 20. .This mechanism is timed so that the rotating shear blades will come together and cut oil the depending mass of glass at the proper time, allowing it to 'droplinto molds. either directly or through the chute 130, which is mounted below the heatin chamber on a stem or stud 32 Vthat 1s a justably held in a bracket 33 pro ectmg from' the frame. A sprayer 34 connected with a water supply is arranged to throw cooling water upon the shears when they are turned back away from under the furnace. Admp pan 35 provided with a pipe 36-is locatedbeneath the sprayer for collecting andconducta ing away the water-which falls from the The mechanism here shown may be driven which it. is associated, as for example by means of a trainjof gears connecting with the gear 29.

The supply of air for preventing the overheating of the gathering-head may be applied in-any well-known way. It is here shown as being applied by means of a swiv-e eling air head or cap 38 mounted upon the;

end of the hollow, shaft 10, so that the latter may revolve within the air c'ap without turning the latter. The air cap is provided with pipe connections 39 and 40, the latter of which is'connected with a supply of air under pressure, and is sufiiciently flexible to permit the'l'longitudinal' movements of the gathering head. The air entering from these pipes through the longitudinally through the hollow shaft 12 in this art.

to the gathering head and returns through:

an interior pipe 41 in a manner well known The outlet for the glass is here shown to be through a closed or tubular spout 1.

- This, however, although preferable, is not an essential feature, since the glass may under some conditions or for some purposes be discharged through an outlet open at the top.

As the reciprocating head is moved away from the outlet it tends to draw out and thus facilitate the flow of the glass,' besides air cap 38 passes "vin it more room to flow around the hind etween the latter and the outlet. The rotary movement of the glass as it is carried by the head tends also to wipe or scour the outlet, thus maintaining a free and clean 'fiow,'and thereby tending to prevent accumulations of chilled glass in and around the outlet, assisted in this respect by the drawing out action above referred to.

The viscous character of the glass makes it vusually unnecessary to move the head close against the spout or outlet to'stop or check the flow of the glass to a suflicient extent.

The range or zone of"longitudinal movement may be adjusted by means of the nuts 16 while-the machine is in operation, thus establishing and maintaining under working conditions, the proper flow of the glass and theextent to which the flow is arrested when shedding the accumulated gather.

To facilitate the ready removal and replacing of the gathering head, a removable cap or half-box 43 is provided for the bearing 1%, held in place by a bolt or bolts 44.

By removing these bolts and the cap 43, and slid ng back the frontwall sections 5 and 5 1 the gathering head and its shaft are free to be removed fromrworking position and another head substituted.

. The slz'e of the outlet and of the gathering head, the degree. of their inclination, v

and other relevant features should be adapted to the character of the glass and the character and the size of the gathers to be formed. Similarly in various ways well understood in this art the various parts should be adapted and adjusted to the performance of their respective functions.
