INTERNAL lNOZZLE FOR TEMPERING BOTTLES AND OTHER GLASS CON- TAINERS Charles E. Mangan, Jr., Hartford, Conn., assignor to Hartford-Empire Company, Hartford, Conn., a corporation of Delaware Application April 26, 1941, Serial No. 390,591

8 Claims.

This invention relates to improvements in nozzles for discharging cooling fluid against the in' ternal surface of a bottle or other glass container to effect tempering of such bottle or container or some other desirable result.

It has been found by experiments that desirable tempering of a bottle or other glass container may be most satisfactorily accomplished by the use of a nozzle having uid coolant discharge orifices of a particular size or of particular sizes at different places along the length of the nozzle according to the particular shape and size or other characteristics of the` particular bottle or container that is to be tempered, the pressure on and the kind of fluid coolant employed, etc. Also, it may be desirable to have different spaces between adjacent discharge orices'in diierent portions of the body of such a nozzle. For bottles or containers of diiferent types or even for bottles or containers of different sizes of the same general type, nozzles individually different insofar as the size or sizes of certain or all of their discharge orifices and as to the spacing of the respective discharge orifices are concerned, may be most suitable. In other words, it may be stated as a general proposition that for each size or type of bottle or container, a nozzle having discharge orifices of a particular size or of particular sizes and of a particular relative arrangement is best suited for the application to the interior of such bottle or container of a cooling fluid of a given kind and under a given pressure.

An object of the present invention is to obviate the necessity of Iproviding completely different nozzles for different sizes and/or different types of bottles and other glass containers in order to use in each instance a nozzle believed to be most suitable for application of a cooling fluid, such as air, to the interior of the particular bottle or container to be tempered.

A further object of the invention is to provide a nozzle of the character described having a construction which will permit the removal and replacement of the portion or portions of the nozzle containing the discharge orifices without thereby necessitating alteration of the remainder of the nozzle or any disturbance of its operating connection with other parts ofv a tempering machine or apparatus to which such nozzle has been applied. l

A further object of the invention is to provide a nozzle of the character described having an elongate tubular body provided with one or more quickly and easily removable and replaceable elongate coolant discharge sections.

A further object of the invention is to -provide a nozzle of the character described having one or more readily removable and replaceable discharge sections extending for a substantial part of the length of the body of the nozzle when in coopera.- tive relation therewith and each of such a construction that the pressure of cooling fluid within the nozzle body tends to maintain such section or sections in place with relation to the remainder of the nozzle body.

Other objects and advantages of the invention will hereinafter be pointed out or will become apparent from the following description of a practical embodiment of the invention, as shown in the accompanying drawing in which:

Figurel is a view, partly in vertical section and partly in elevation, showing my novel nozzle operatively supported in relation to a glass bottle that is to be tempered;

Fig. 2 is a relatively enlarged longitudinal vertical section through a portion of the nozzle body and the nozzle tip, substantially along the line indicated at 2-2 of Fig. 1;

Fig. 3 is a still further enlarged transverse section through the nozzle body substantially along the line3-3 of Fig. 2;

Fig. 4 is a view showing in elevation a fragmentary portion of the nozzle body, with an outer layer portion of the nozzle body partially broken away to reveal underlying parts; and

Fig. 5 is a vertical section through the tip and adjacent portion of the nozzle body substantially along the line 5 5 of Fig. 3, but on a relativelyreduced scale.

A nozzle embodying the invention may comprise an open ended tubular body I0 formed of any suitable metal or other material. This body I0 may be provided with one or more longitudinally extending dove-tailed slots I I extending from the free end thereof for a substantial part of the length of the body, as for a suilcient part of such length to adapt the nozzle body for use in the tempering of bottles and other glass containers having substantially different heights. As shown, the nozzle body Ill has two of the dove-tailed slots I l, these respectively beinglocated diametrically opposite each other as best seen in Fig. 3.

Each of such dove-tailed slots may be open throughout the full length and width thereof at the inner surface of the body l0. The bottom Wall of each dove-tailed slot Il may be provided ings or slits I2 of the series at the bottom o1' each dove-tailed slot II may be of the same or of individually diil'erent lengths and each may be spaced at one end from the adjacent elongate opening or slit by an imperforate portion of the dove-tailed bottom wall or land as indicated at I3. When the nozzle body is provided with a plurality 'of the dove-tailed slots, as in the example shown. in the drawing, the generally corresponding imperforate portions or lands I3 for the several dove-tailed slots may be located at different places along the lengths of such slots or staggered so as to cause overlapping vertically of the elongate openings or slits I2 at the bottoms of the several slots II. This is shown to advantage in Fig. 2.

A removable and replaceable slide member I4 in the form of an elongate strip or ribbon of a suitable material, such as phosphor-bronze, for example, is provided for each of the dove-tailed slots II. Such strip is provided with longitudinally spaced jet holes or discharge openings I5. These may be arranged in a number of longitudithe drawing, thicker and less ilexible strips or segments may be provided. These may 'be formed nally spaced series so as to leave the portions of the strips beneath the lands I3 imperforate or any selected or preferred relative arrangement or spacing of the respective jet holes or discharge openings I5 may be employed. All these openings I5 may be of the same size or certain of them may be of sizes different from the others. The controlling factor will be the cooling pattern or curve to be obtained by discharge of cooling uid, such as air, from the nozzle body through the strip against different portions of the inner surface of a bottle, such as that indicated at B in Fig. 1, or other glass article that is to be tempered.

The strips I4 may be formed of a material having sufiicient flexibility and spring qualities to be compressed laterally to a slight extent between the side walls of the dove-tailed slot in which such strip is disposed (see Fig. 3). The strip may be inserted end-wise into the slotat the open end of the nozzle body. 'I'he tip of the nozzle, indicated at I6, may be removed to permit convenient manipulation of the strip in eiecting such insertion.

If a relatively iiexible strip of slight thickness is employed, asr shown in the example, such strip may have is outer end portion bent inwardly, as indicated at Mato project into an annular groove I'I in the periphery of the tip I6 when the latter has been applied `to the nozzle. This tip may have a substantially hemispherical head portion and a relatively short tubular attaching body portion adapted to t within the free end portion of the nozzle body and to be fastened in place in any suitable way, as by means of the screws I 8, Figs. 3 and 5. As best seen in Fig. 2, pins I9 may project from the tip I6 at the part thereof containing the peripheral groove I1 againstfthe inturned end portions I4a of the strips. These pins extend radially outward from the tip at least to the planes of the strips so that such pins may be employed to retain such strips against accidental sliding movements relative to the body in the direction of the tip even though such strips be formed without the inturned end portions Illa. These inturned end portions of the strips may serve to cooperate with the nozzle tip to retain the strips against accidental longitudinal displacement in either direction from their inserted positions in the slots of the nozzle body.

Instead of a strip of the narrow gauge material indicated by the showing of the strips I4 in either with or without inturned outer ends corresponding to the ends I4a of the strips I4.

As many different kinds of strips-may be provided for use at different times with the same nozzle body as there are different, kinds of bottles or other glass articles to be tempered by the use of tempering apparatus including such nozzle. Each such strip may have its own particular arrangement of jet holes or discharge openings of the particular size or sizes and location which will best adapt .that strip for use as a coolant discharge member for applying the coolant to the interior of a bottle or glass container of a particular size, shape or type.

As shown, the tip I6 has discharge orifices 24 extending radially in three different rows from the center of the forward part of the tip, these rows being equidistant apart as best seen in Fig. 3. The attaching portion of the tip is shown as also having openings 2| to permit passage in lateral directionsof coolant from the interior of the tip to certain of the openings in the adiacent portions of the strips I4. It is to be understood that nozzle tips having different discharge openings or different arrangements of discharge openings may be provided and used interchangeably so that the tip having the most suitable cooling fluid discharge provisions for a particular cooling fluid discharge strip or strips may be used with such strip or strips.

The nozzle body I0 is shown in the drawing as having been formed of concentric inner and outer tubular members but these may be made in one piece. The attaching portion of the nozzle tip likewise is shown as having a separately formed outer ring member which maybe integral with the remainder of such tip.

The nozzle body I0 may be supported for rotation about its longitudinal axis by any suitable known means. I prefer however to make use of a structure which will steady such nozzle against lateral oscillations and wabbling, As shown in Fig. 1, the nozzle body is connected by screw threads at 22 with a nipple 23 which carries a driving gear or pinion 24. The nipple 23 is connected by screw threads at 25 with a tubular suspension member 26 which has an outturned flange 2'I supported anti-frictional'ly, as by the ball bearing assembly 28, within the rela.- tively enlarged upper end portion 29 of a supporting sleeve 30 which is mounted in a suitable opening in a stationary frame member 3|. The nozzle body I0 is further stayed and rotatably supported at a lower level by the vertically disposed needle bearing unit 32 which is mounted on the nozzle body IIJ between the retaining rings 33 and 34. The bearing unit 32 includes an outer tubular member 35 which extends vertically through a suitable opening 36 in a stationary frame member 3'I and has an outturned ilange 38 resting upon the frame member 31, so that the bearing unit is supported by the latter.

It will be understood that a nozzle embodying the present invention may be used with any suitable means, none being shown, for applying coolant to the external surface of a bottle or other glass container that is being cooled internally by the use of such nozzle.
