HAROLD A. ROHRICH, OF TOLEDO, OHIO, ASSIGNOB TO THE OWENS BOTTLE COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

GLASS-FORMING MACHINE.

Application filed February 24, 1926. Serial No. 90,299.

My invention relates to improvements in machines for the manufacture of glassware, and particularly to a machine comprising a rotatable mold carriage including a series I of blank molds into which the charges of glass are .introduced, and cooperating neck molds by which the bare blanks or parisons are suspended after being formed in the blank molds and after the latter have opened.

An object of the present invention is to provide an improved means for simultaneously and uniformly cooling or chilling corresponding sides of a plurality of suspended blanks, such improved means being adapted to direct a plurality of sheet-like air jets from spaced orifices in order that the several blanks suspended from double, triple or other multiple molds may be treated to retain them in true vertical positions.

The present invention is based upon the principle embodied in Patent No. 1,299,482, dated April 8, 1919, and through the revised structure herein disclosed, is, as above stated, adaptable for use without structural alteration or adjustment, in connection wit single, double or triple molds.

, Other features and advantages will be apparent hereinafter.

In the accompanying drawings which illustrate the preferred construction embodying the principles of my invention:

Fig. 1 is a dia ammatic plan view of a rotary mold carriage and associated arts, all of conventional form, the improved type of nozzle being illustrated in connection therewith.

Fig. 2 is a detailed vertical sectional view showing the relation of the blast nozzle, air supply pipe, air flow control, and the suspended lank.

Fig. 3 is a detailed top plan view of the nozzle and air feed pipe.

Fig. 4 is a front elevation of the nozzle and air feed pipe.

Fig. 5 is a transverse sectional view taken substantially on line VV of Fig. 4.

Fig. 6 is a front end elevation of one. of the mold carrying units, showing double 50 molds associated therewith.

The present invention is herein disclosed as applied ,to a machine of the type illustrated in Patent No. 1,185,687, dated June 6, 1916, :and includes a mold carriage 7 which rotates continuously about a central standard 8, and mounts a plurality of radi ating heads or mold carrying units 9, upon each of which is arranged in the usual, or any preferred manner, single, double or multiple molds 9 which may be of conven tional form. As in the Patent, 1,185,687, above referred to, the charge of molten glass is transferred as by suction from the glass tank 10 to the molds, and is then treated in the usual manner as a result of which, the final form is assumed.

During the rotation of the mold carriage, there is a tendency of the suspended blanks to swing outwardly, due to unequal degrees of cooling as between the outer and inner sides or portions of the blanks immediately below the neck, and in order to overcome this fault and maintain the blanks in truly vertical positions and at the same time provide for simultaneous coolin of a'plurality of blanks, as well as single lanks or parisons 9", I employ a structure which may be described as follows:

This improved cooling or chilling means comprises, in its broadest form, an elongated nozzle of sufficient len h to approximately span one of the mol carrying units, the nozzle being so spaced from the points at which the blanks are suspended, that jets of air. emitted from longltudinall spaced orifices, coact with each other at t e points of contact with the blanks to form a continuous or single substantially flat, sheetlike, cooling blast.

Each nozzle or head 11, as shown in Fig. 4, is provided at its media] point with an upwardly extended inlet neck 12, providing means for attachment of the nozzle to an air feed conduit 13, illustrated as consisting ofseveral sections interconnected by elbows 14 and mounting at the up or end, a feed control valve 15, which, as s own in Fi 2, is rigidly fixed to an adjacent portion 0 the carrying frame. Below this valve 15 in the air conveying pipe, is a pressure control valve 13'.

As in Patent No. 1,299,482, above referred to, the valve 15 is ada ted for intermittent operation by means o a stationa control cam 16 which acts upon'a roller 1 carried by the usual valve stem.

It will be noted that sets of jet orifices 18 are uniformly spaced with respect to each shallow, with the result that orifices of slot-.

low body, thereby confinin .20 whose lower face extends through the bottom wall of the body forming at each side of the inlet 12, a continuous slot 21 extending longitudinally of the lower wall and communicating therethrough with the interior of the body. This peculiar formation of the slot with respect to the flange,

results in the creation of a longitudinal shoulder 22 which forms an abutment adapted to contact with the adjacent edge of abase plate 23, this base plate, as shown, being provided with longitudinally spaced, transversely extending ways or channels 24 which provide communication as between the interior of the body and the atmosphere. As is noted, these ways 24 are extremely like configuration are formed for the purpose he'retofore pointed out. I

By reference to Figs. 4 and 5, it will be noted that the upstanding portions between the transverse channels, serve to close portions of the longitudinal slot 21in the hol-. ejection of pilasts of air to the uniform y spaced orices.

At suitable points, machine screws, or like fastening elements, may be, and. preferably are, employed to eifect rigid connection as between the base plate and the lip or flange, though it is to be understood that in some instances the portions herein referred to as lips and base plates, may be of'integral formation.

In order that inaccurate impingement of air jets upon the blank (such as is often the result of vibration of the machine),

may be eliminated, I form mediall of and at the lower end of the rear we of the nozzle, an apertured ear 26' which, by means of a bolt or the like fastener, is rigidly connected to a fixed part 25 of the carrying frame, thereby minimizing the objections stated.

It will be. noted by reference to Figs. 2 and 3, that longitudinal spacing of these slot-like orifices results in a creation of separate fan-like "blasts of air, which at their points of contact with the suspended blanks eing cooled, coa'ct witheach other in the formation of a relatively long, substantially fiat, blast, which is of such width as to effect chilling of blanks whether they be carried by sin le, double or triple molds. Further, it will e noted that each nozzle is formed with two sets of these orifices uniformly s aced from the center, by reason of whicii, two, four or six blanks may be simultaneously treated. -At this po nt, it should be notedthat each mold carrying unit or arm is to be'provided with one of these nozzles, and that the molds may be of types to suspend, single, double or triple charges of molten glass.

'VVhile I have quite specifically set forth the preferred form, it is understood that certain changes in details of construction, may be resorted to without de arting from 'the spirit of the invention as c aimed.
