KARL E. PEILEB, OF WEST HARTFORD,

FAIBMONT COMPANY, 01' HARTFORD,

YORK.

CONNECTICUT, ASSIGNOR TO HARTFORD- CONNECTICU'T, A CORPORATION OF NEW FEEDING MOL'IEN GLASS.

Application filed November 25, 1825. Serial No. 71,869.

To all whom it may concern:

Be it known that I, KARL E. PEILER, a

' citizen of the United States, residing at West Hartford, in the county of Hartford and State of Connecticut,- have invented certain new and useful Im rovemcnts in Feeding Molten Glass, of whichthe' following is a specification.

This invention relates to improvements in the art of feeding molten glass from a melting tank, apot, or other container or source of supply, and delivering it in mold charges of uniform and controllable size and shape to apparatus for pressing, blowing or otherwise fabricating the charges into glassware. This application is a continuation of several prior applications, as pointed out below, and. is filed for the pur ose of claiming an important advancein t 1e glass feedin 'art whichhas been given the name of pliase-changing.\ This expression, as used herein, should be-- understood as meaning change in the relative time of occurrence of theoperations controlling the formation of the mold char es, ready for severing, and the operation 0 severing these mold charges, as these operations are repeated in successive cycles. Variation in this relative t me accomplishes valuable results in respect to con trollin the shape and Weight of the deliver-e charges. It has been developed b methrough a series of mechanisms WlllCl constitute a. series of progressive improvements, and several of these mechanisms are shown, herein for the purpose of indicating the manner in which this invention has been developed. The invention, to be protected hereby, contem )lates-in one of its broader aspects {fie met od in which glass in a viscous con- 1 ition is intermittently allow to sagdown from an ov'erheadsupport past a severing plane'to form a mold charge in suspension )elow the severing plane. The char e is severed from the glass remaining e vs .thc severing plane and is then received in a mold. The shape, particularly the length, of the severed charge is influenced and com "trolled by properly coordinating the time of severance in relation to the essential steps which )roduce the suspended mass from which the charge is to be severed.

Variations in this relative time between the severing operation on the one hand and other operations influencing the formation of the charge on the other hand. herein termed phase-changing, produce changes in the shape of the charges.

In certaln forms of this invention shown herein, a variation in the time at which the glass for the mold charge issues from a furnace is made in res ect to the time of severance. In such em odiments of this invention, the variation in phase between feeding and severing may accomplish not only a regulation of the lengths of the severed charges, but also a regulation of the weight of the charges.

The later developed forms of the invention herein claimed contemplate, in combination with the phase change before referred to, lifting the stud of glass left after each severing o eration at a variable time in res ect to tie timeof severing, in order to s ape the lower end of the stub of glass left above the severin plane and to thus shape the lower end of t e next succeeding charge. Phase-changing between lifting the lass and severin the glass is specifically claimed elsewhere y me, and is therefore not claimed per se herein.

Not onlv does my invention involve the methods above stated, but also apparatus for carrying out those methods.

T e several prior applications in which this invention is disclosed in various as-.

poets, and of which this application is a continuation in part, include an application SerialNo. 713,143, filed August 3, 1912, an, application Serial No. 157,943, filed -March 28, 1917 (it in itself being a continuation of application Serial No. 856,548, filed August 13, 1914), an application Serial No.

294,792 and an a plication Serial No. 294,- i

793, both filed ay 5, 1919.

It is a prominent characteristic of molten less that when it issues or is withdrawn -rom the furnace or other container. and is exposed to the colder surroundin outside of the furnace it acquires a partia ly chilled surface "or .sltin, known in this art as enamel. This enamel is coldest and stifiest on its outer surface, and gradually mer s into the'hot and more plastic interior of t e glass. When a. charge of this glass is delivered to a. mold, any undue stretching, rupture, or infoldin of ithe e'namelwill cause defacts in the article being made. Any trapmold, so that its external contour will closely approximate the interior contour of the mold walls, or at least that portion of the mold which receives the charge.

This is of special importance in the making of blown glassware. A mold charge which is to form a narrow-necked bottle,

for example, should be pre-formed as an elongated cylinder, so that its entire surface may as ncai-l as possible contact equally with the mold walls for the same length of time. Unequal contact of different portions of the surface, or unequal duration of contact of the different portions, tends to produce an unsymmetrically chilled and enameled blank or parison, which will not blow out uniformly, because the hotter portions will stretch more than the cooler portions, resulting in a poor bottle having a wall of uneven thickness.

These conditions have evidently been recognized to some extent by the hand gatherer, practicing his ancient art, who, by manipulation of his punty or gathering rod during the gathering operation, performed his gather or mold charge, as well as he could by this primitive method, to fit the mold, or that portion of the mold that receives the gather, thus attempting to avoid undue deformation of the mold charge when deposited in the mold. On the other hand, these conditions have received little or.no attention in the gathering or feeding of molten glass as heretofore practiced by machine or other automatic methods prior to my invention of the apparatus herein disclosed. The present application is concerned with the accomplishment of this shaping by the aid of the phase-changing operations outlined above.
