To all whom it ma tz'o'n'cerri, Be it known that I; VV'ARREN E. GIJA'SBEY, a citizen of the United States, residingjiat Bridgeton, in the county of Cumberland and State of New Jersey,have invehtedjanew" and useful Improvement in Ma'cl1i'11 esfor Making Bottles, Etcfofwhich the following is aspeciiic'ationa This inventionrelates pa'rticularlyto ma chines for makingbottles,"or similar 0011-.

The invention is illlustrated in'fits preferred embodiment in the accompanying drawings, in Which Figure 1 reperesents a broken'pla-nf'view of a bottle-making machine embodying f the invention Fig. 2, a broken, elevational view of the same; F ig, .3, a broken,verticalsec tional view illustrating;particularly the means for-elevating the mandre1s,the"view being taken approximately as indicatedfat line 3- 3.of Fig. 1; Fig. {.L,"a plan section on anenlarged scale takenas indicated at line 4-4 of Fig. 8. and iilustrannga" clutch device employed; Fig. '5,a plan s'ection on an enlarged scale taken as indicated atline 5 5 of Fig. 3, and illustrating a coupling, or connection, between theclutch-heathand its actuating shaft; Fig. 6,a'fbrokenfeleva tional view, partly in section,ftheview being taken at the glass-chargingstation, approximately as indicated at line 6-'6 ofFigJ'l; Fig. 7, a broken, vertical-sectionalview, taken at the blowing station, approximately as indicated at the line 7 7-of "Fig. lfland Fig. 8 is a plan view, partly insection', taken on the line 8. 8.ofFig.

It may be stated preliminarily that a bottle-making machine of th'egeneral type illiistrated is known, such niachineiinvolving the use of a rotary mold carrier has ing an inverted mold mounted on *the carrier. Each mold has associated with it a mandrel provided with a thread equipped tip", the shank of the mandrel being threaded", and working, through a nut carried with? the 3 mold. In accordance with the present iii-f vention, the lower end of each f'nriaiidrelshanlfli's equipped witlr'a pinion, or'colla'r; Which has its lower side provided vvith clutch-lugs andco11ti1iuously operating cal gear mechanism is employed forraising and'floiver ing the mandre'lg suchgear mechanisin comprising a pair of clutch-members disposedbeneath the path'ofthe man'drels; one-clutch-member being locatedat the-mam dretaevatin station," and the other olutchmember" being 'locatedat thebloiving Sta tion." {These clutch-members rotatel in op pos'ite directions; and each: is 3 provided with clutch-lugs for-engagingthe clutch-lug with which the mandrels'are providedy'when the mandrels are brought, in turn, in position above theclutchmembers; 1

4 The name; which c0mprises"the .base A and, column A may be "of any suit-able 'constr uotion'. {The thick "center? column:

is,-at the gIaSschargthe glass-charging station is designated H (Fig.6), and is of the usual construction. The blow back head I employed at the glass-blowing station, (Fig 2) is also of well-known construction. It is lowered onto the mold previous to the bubble blowing operation.

The mold table is given anintermittent, or step by step, movement in any desired manner. The .mo-ld carrying means comprises a table B, and the series of mold supports'B arranged'thereon. Each mold support B is provided with a hollow trunnion, or gudgeon, 1, anda disk, or faceplate, 1 formed integrally therewith. The hollow trunnion 1. is journalledin a divided bear- 1 sections 3 ing box 2, which is securely fastened to the table B. Each mold B comprisesa pair of main mold sections 3, and a pair of ring mold These sections meet in a vertical plane and are carried by arms 3 and 3, respectively, whose inner ends are mounted on a pivot 4 carried by lugs P which'project from the face plate 1. Thus, the mold sections are capable of separating at a plane containing the axis of the mold.

The threaded mandrel E, associated with eachmold, works in a nut 5 which is rigidly secured to a bracket 5 projecting from the lower portion of the face plate 1. The

bracket 5 has a tubular portion 5 in which the nut 5 is rigidly secured, and the upper end of said tubular portion is equipped with a flange 5which interlocks with an internal groove with which the ring sections are provided.

. Inthe operation of the machine, the man- 7 dre ls are elevated, in turn, by the rotating head or clutch-member, 'F which turns in a. direction to cause the mandrel to be screwed upwardly. The clutch-member F is driven by ashaft, which, in turn, is frictionally driven by a continuously rotating gear, the

arrangement being such that the shaft will shown in the drawing are designated S S andS The .madrelsare. elevated at the station" designated S the glass-charging itself properly with the mandrel.

operation and the operation of blowing the glass down into the lower portion of the mold is performed at the station designated S and the complete withdrawal of the mandrels is effected by the head F at the station designatediS The reverse, or unscrewing, movement of the mandrels is started, however, by the device G, during the passage of the mold from station S to station S Themold sections are opened and closed through the medium of a plunger 6 which extends through the hollow trunnion 1 of the mold support, the outer end of the plunger being connected, by links 6, with the mold section-s. Each plunger 6 is equipped at its rear or inner end wit-h a cam roller 6*; and the movements of the plunger 6 are controlled by the cams C and G.

On the hollow trunnion of each mold support is secured a bevel gear 7 These bevel gears are adapted to travel on the bevel rack D and revolve the mold supports on their axes during the rotation of the mold tableB.

, The molds may be maintained in their normal upright position by any suitable expedient, such as latching devices 8 of which one is shown in Fig. 2. Such a device forms no part of the present invention. It may be added, however, that the device comprises a spring projected plunger 9 adaptedto engage the periphery of the face plate 1*.

.Each mandrel E preferably comprises a tubular shank portion 10 and a tip portion 10 which is provided with a thread adapted to forma thread inthe mouth of the bottle. Such thread corresponds in pitch-with the pitch of the thread 1O between the shank 10 and the nut 5. The tip portion 10 is provided with a tubular shank 10 and a collar 10 Air may pass through the tubular shanks Y10 and 10 and out through radial openings 10*, thus gaining" access to the chamber 11 above the nut 5. The chamber 11 communicates through a central passage 11 with the neck portion of the'mold cavity. Thus when the mandrel is retracted, air may pass from the'bubble blower into the cavity in the glass and blow the glass to complete parison form.

The local gear mechanism E, which includes the mandrel elevating head, or clutch,

F and mandrel lowering head, or clutch, 13

will now be more fully described. Each of said heads is located directly under the annular path of the pinions, or clutch-members E carried ,by'the mandrels; and each of the clutch-members F and F is so mounted on the ,upper end of a vertical shaft 12-as to permit a certain amount of swing to enable the clutch-member to aline Each shaft 12 is splined in a frictionally-driven Thus, 20
