Patented July 9, 1940 UNITED STATES PATENT OFFICE MACHINE FOR MAKING PURELY PRESSED GLASSWARE Application September 11, 1936, Serial No. 100,246 Renewed December 16, 1939 i 6 Claims.

This invention relates to a machine for making either blown or purely pressed glassware. By 'purely pressed glassware is meant ware which is produced solely by pressing without the 5 application of any air for the purpose of shaping the ware being produced.

The general object of the invention is to provide means whereby a feeder-fed glassware form ing machine for producing glassware by the nar- 10 row neck method may .also be employed for producing purely pressed ware, thus increasing the utility of such machine. For the purpose of simplicity, the feeder-fed forming machine operating on the narrow neck principle is referred to hereinafter as the narrow neck machine or type of machine, and the type of ware produced on said machine is referred to as "narrow neck ware, irrespective of whether the ware has narrow necks, this term identifying the ware by the method and machine on which it is made.

A more specific object of this invention is to employ a narrow neck machine for making purely pressed ware by utilizing certain of the parts of such machine heretofore used only for actuating the narrow neck forming instrumentalities, for actuating pressing and pressed ware handling instrumentalities. For this purpose, it is preferred to use pressing means which can readily be attached to and removed from permanent operating parts of the narrow neck machine so that the narrow neck forming instrumentalities, which as usual are removable, may be replaced when desired. It has been found in practice that in this way the machine can be changed from the production of narrow neck ware to the production of purely pressed ware (or vice versa) in normal job-change time, that is, within the period usually necessary to change molds and other parts when the machine is used only in the production of different kinds of narrow neck ware.

Other objects of the invention will be brought in, or will become apparent from, the description of an embodiment of the invention illus-. trated in the accompanying drawings, wherein:

Figure 1 is a view in vertical sectional elevation of a portion of a narrow neck machine embodying the invention, parts being omitted for clarity in illustration;

Fig. 2 is a similar view on enlarged scale, showing in detail the means for pressing the ware;

Fig. 3 is a view similar to Fig. 2, but showing in detail means for receiving, cooling and discharging the pressed ware from the machine; and

Fig. 4 is a view illustrating the operation 01 supporting and cooling an article of ware in preparation for its discharge from the machine.

For purposes of illustration and not in limitation of the invention, the illustrated embodi- 5 ment (Fig. 1) consists of the adaptation of the invention to one section of the Hartford Individual Section Machine, disclosed in the patent to H. W. Ingle, No. 1,911,119, dated May 23, 1933, it being understood that the same adaptation may be made to any number of sections of such machine.

As shown in Fig. 5 of the Ingle patent, each section of such machine comprises a blank mold and neck pin located at the blank forming station and with which cooperate a delivery funnel,

a settleblow head and a neck mold. These and the other narrow neck forming devices are re-' movably attachedto their respective operating members for the purpose, but only for the purpose, of substituting, other similar devices in changing from the production of one size or style of narrow neck ware to another.

Similarly, as shown in Fig. 1 herein, the base of the machine 6 supports vertical shaft 1 for the holders, one of which appears at 8 which in Ingle carry the blank mold sections. At 9 is shown what in Ingle constitutes the neck pin operating mechanism, at H (Fig. 2) Ingle's funnel carrying arm, (in which funnel l2 of the present invention is removably secured by ring l3), at I4 an arm similar to Ingle's settle-blow head arm and at I5 Ingles inverting neck mold carrying and transfer arm.

Each section of the machineof the patent also includes a blow mold at the finish blowing station and hence Fig. 1 herein shows the vertical shaft I 6 for the sections of such mold of the patent (not shown), and the member H for tilting the blow mold bottom plate (not shown) of 40 the patent. Also shown atthis station is a fin-. ish blow head I8 and Fig. 1 shows at IS the finish blow head operating arm both substantially as shown in the patent to Ingle.

The operation of the actuating or carrying members ofthe narrow neck machine will be explained hereinafter, it being desired first to describe the utilization of such members in the operation of pressing and pressed ware handling .devices.

Referring to Figs. 2 and 3, it will be seen that. the neck mold carrying arm has removably fitted therein a sectional holder, as indicated at 2|, which carries the sections of pressing mold 22, and a solid mold bottom or closure 23, to form 65 a mold cavity of the shape desired, in this instance for forming a threaded fuse case. The mold bottom 23 has a lug 29 thereon which is received in an opening 25 of the neck pin mechanism 9, whereby the latter serves to center the mold bottom and the mold 22 for registration with pressing ring 26. As will be apparent from Fig. 2, mechanism 9 serves as a support or rest for the pressing mold during the operation of pressing.

Ring 26 is secured in and forms part of funnel l2 by screw means, as shown, and these parts receive therethrough pressing plunger 21, for the operation of which the plunger carrying arm I4 is employed.

The plunger assembly includes casing 28 removably secured in known manner in the arm It, as by means of lugs and flanges or a bayonet joint, as partially shown, this casing containing spring pressed plunger sleeve 29 which fits into funnel l2 and in which plunger carrier 3| is slidably mounted under pressure of spring 32 in cage 33 on the casing. The downward movement of the plunger assembly is stopped by spring 34 engaging shoulder 35, the degree of pressure applied to the plunger depending upon the strength of spring 32, as will be understood.

To insure that the mold sections 22 will remain closed during the pressing operation, the blank mold carrying arms 8 (Fig. 2) are employed as a mold lock to the holders 2| for the mold sections.

The funnel carrying and plunger carrying arms I I and M are oscillated and lowered by the shafts upon which they are mounted by means shown in detail in the Ingle patent. Said patent likewise discloses means for vertically adjusting the neck pin operating mechanism 9 which isheld in fixed position for centering the mold bottom 23, and the means for operating holders 8, as well as the mechanism for inverting arm l5. Such mechanism is partially shown in Fig. 1 and includes oscillating shaft 31 carrying gear 38 engaged by rack 39 which is reciprocated by a piston (not shown) in cylinder 4|.

The mechanisms for oscillating and lowering finish blow head 18 and the bottom plate carrying member I! also are shown in detail in the Ingle patent. The functions of these members in making pressed ware are as follows.

The inverting of arm I5 inverts the press mold into the position shown in Fig. 3 in registry with discharge member 43 which replaces the blow mold at the finish blowing station, whereupon the finish blow head is lowered to engage opening 42 therein with lug 24 on the mold bottom 23 for centering the latter and stripping the pressed article from mold 22. At this position, the mold is opened in the same way as in releasing a blank for a narrow neck article, preferably by the 7 means provided in the Ingle patent for opening the neck ring of the narrow neck machine. This serves to deliver the pressed article to the ware cooling and discharge device 43.

This device 63 is removably secured to the bottom plate carrying member ll by a bayonet joint indicated at M, and its upper end is shaped to conform to the interior of the pressed article, as indicated at 45. In order to support and cool the pressed article, and out' of contact with member,

33, an air jet is delivered through orifice 46 in member 43 into the cavity of the article. This serves to hold the article out of chilling contact with the discharge member 43, as illustrated 'in Fig. 4. While so held, cooling air may be applied to the article from opposed nozzles 41-41.

aecaera Thus the article is cooled both internally and externally. When cooled to the desired degree, discharge member 93 is moved'vertically downwardly to clear the mold 22 and then tilted by the operation of the mechanism normally used for lowering and tilting a bottom plate. The details of such mechanism may be best understood by reference to the Ingle patent. It is sufiicient to explain here that member I! is pivoted at 48 and is held in horizontal position by spring 49 until moved vertically downwardly the length of slot 5|, whereupon member I! is tilted into the dotted line position of Fig. 3. These operations are caused by a piston (not shown), the rod 52 of which is connected to member I! by links, one of which appears at 53. Such movement delivers the article to a slide 54 having a slot 55 therein, through which works discharge device 43. The article comes to rest on a dead plate 56 and is then pushed onto conveyor 51 by a pusher indicated at 58.

Various types of pressed ware may be produced by the machine embodying this invention and changes made in the construction and operation of the several parts without departing from the scope of the appended claims. The design of discharge device 43 may be changed to suit different types of ware.

From the above description and the drawings, it will be seen that my invention provides novel means whereby a narrow neck machine'may be employed in producing either narrow neck ware or purely pressed glassware, the instrumentalities for producing the one type of ware being quickly and easily replaced by the devices for making the other type of ware. Also, exchangeable devices may be used for making different kinds of pressed ware.

It has not been considered necessary to illustrate herein timing mechanism for timing the automatic operation of the various parts of the machine with each other and with the feeder (not shown) for delivering successive charges of glass to funnel l2 because timing mechanism for this purpose is disclosed in the patent to Ingle referred to above and by simple adjustments is employed in the production of either pressed ware or narrow neck ware, as desired.
