8 Claims.

The present invention relates to tempering hollow glassware, such as bottles and jars, each of which has a single restricted opening.

It provides a novel internal cooling nozzle adapted to enter the ware through the restricted opening and to apply a cooling medium as, for example, air or steam, to the internal walls by a plurality of jets, and to remove the spent medium through a plurality of spaced exhaust openings. The nozzle is so constructed and arranged as to provide a large number of closely spaced jets of cooling medium originating from holes, distributed substantially completely over the portion of the nozzle surface below the entrance to the neck of the ware. These holes are of such number and size and so directed toward the walls of the ware as to bathe the entire surface of the walls with chilling medium without necessarily causing relative rotation or other movement between the ware and the nozzle. If desired, however, the nozzle and the ware may be moved relatively to each other either about or along the axis of the nozzle, or both, and the movement may be either rotary, oscillatory and/or reciprocatory.

A principal object of the invention, therefore, is to provide such a nozzle which will completely bathe the inner walls of the article with chilling medium in accordance with a pattern which is selected or predetermined in accordance with the characteristics of the bottle.

A morespecific'obiect of the invention is to provide a new and useful construction of nozzle by which the above stated objects may be readily accomplished.

The nozzle may be employed as part of any suitable apparatus as, for example, that disclosed in the application of Thomas D. Green, Serial No. 306,085, filedNovember 25, 1939, by which the glasswarQwhile being cooled, may be held by tongs and locked in proper alignment by a member contacting the rim of. the

ware, and by which, when desired, the rotary and/or reciprocatory movement of the nozzle and ware, one relativeto the other, may be effected.

The above recited and other features of my invention will be apparent from the following specification directed to a practical embodiment of the invention as shown in the drawing, in which:

Figure 1 is a view, principally in vertical section, of one form of nozzle of my invention shown in association with a narrow neck bottle held by tongs and, a locking member, a portion of the nozzle being shown in elevation.

Fig. 2 is an enlarged section on line 2-2 of Fig. 1, and

Fig. 3 is a view in elevation of a combined tong and nozzle supporting and operating mechanism with which the nozzle of Figs. 1 and 2 may be employed, the view also showing an associate device, for cooling the bottle externally.

The apparatus of Fig. 3 is substantially the same as that shown in the aforesaid Green application and as shown, comprises a tubular carrier ll mounted in a bracket l2. Within the carrier II and extending above and below it is a tubular member l3 which carries a sleeve ll providing a mounting for tongs [5. A locking member I6 is mounted on the lower end of the tubular member [3. The member l3 and tongs l5 are mounted for rotation, when desired, through a beveled gear l8 and through connections shown by a motor I9. If desired, the gear i8, and hence the member l3 and tongs l5, may be given an oscillatory movement by the substitution of means, not shown, for the driving means illustrated.

The nozzle 20 is removably carried by a pair of concentric tubular members 2| spaced apart but secured together within the member l3, above which they extend, to carry the beveled gear 22 by which the nozzle may be rotated or oscillated about its axis, the means shown being adapted for rotation of the gear 22. It

is to be understood that these means may, if desired, be altered to efiect oscillation of the gear.

The nozzle may be moved vertically relative to the article of glassware gripped by the tongs by means including the lever 23 and link 24, connected to sleeve 25 of the member 2| between the collars 26 and 21. This reciprocation may be periodic and in accordance with any desired pattern and may be caused by a cam (not shown) operating on the lever 23. The external cooling device indicated at 28 may be rotated through sprocket 29.

The locking member l6 may, if desired, be provided with serrations 30 to provide exits of selected size for a predetermined portion of the spent cooling medium which passes through the restricted opening 3| between the nozzle and- .the walls of the'finlsh, to scrub the internal walls of the neck of the bottle. Such an arrangement may provide adequate, without excessive, chilling of the neck of the ware.

The nozzle 20 is provided with an outer tubular shell 32 and an inner casting 33 providing an internal bore 34 and longitudinally extending radial ribs 35, through which are a plurality of passages 36 communicating with jet holes 3! in the shell for the introduction into the bottle of cooling medium from the bore 34. The spaces between adjacent ribs 35 and the shell 32 provide a plurality of longitudinally extending exhaust passages 38 which communicate with the interior of the ware through exhaust ports 39.

The cooling medium is supplied through the pipe 43 and passages (not shown) to the bore 34, and the exhaust is through other passages (not shown) from passages 38 to exhaust pipe 44 (Fig. 3).

The lower end of the bore 34 may be closed by a removable tip 40 which is provided with a plurality of closely spaced jet holes 4! through which jets may be directed upon the bottom and lower corners of the ware. The passages 38 are open at the bottom of the nozzle and provide exhaust ports 42 adjacent to the bottom of the bottle.

In Fig. 2 the ribs are shown as being 12 in number, but obviously this number may be increased or diminished as may be desired. When the nozzle and ware are to be maintained relatively stationary, the greatest number of such ribs as may be conveniently provided is desirable to provide as great a number of jet openings as possible. As shown in Fig. 1, the jet holes 31 are arranged in closely spaced relation'circumferentially of the nozzle and in closely spaced relation in vertical rows throughout all portions of the periphery of the shell from the lower end thereof to a point just short of the neck of the bottle. The exhaust ports are similarly arranged in closely spaced circumferential and vertical rows, the rows of exhaust ports alternating with those of the jet holes.

It is to be understood, however, that the exhaust ports may be otherwise arranged so long as they provide sufiiciently localized and adequate exhaust ports to remove the spent gases Without undue interference with the intended operation of the cooling jets. If desired, as in cases where relative cross sections of the opening into the bottle and of the lower portions of the cavity thereof create such divergence of the cooling jets as to create any tendency toward spotty or local cooling, the nozzle may be rotated or oscillated and/or reciprocated to cause the jets 1 to scan the inner surface of the bottle, and thus avoid such spotty chilling.

Obviously the inlets or the exhaust openings may take the form of elongate openings or slots and these may overlap so long as they provide jets in suitable number and kind to effect the complete bathingof the surface that is to be made without departing from the invention as expressed in the accompanying claims.
