Improvement in Machines for Making Hollow Glassj -ware, and do hereby declare that the following is a bill", clear, and exact description thereof, reference Qheing had to the accompanying drawings, in which- I Figure 1 is a front elevation of a glass jar making lf.machine embodying my invention Fig. 2 is a side Tielevation wit certain parts in sections. Fig'. 3 is a vertical sectio onthe line H of Fig. 1. Fig. 4 is a detail section on the line H of Fig. 2. Fig. 5 is a horizontal section on the line-H 'of F 4. Fig. 6 is a detail view and side elevation of the automatic table locking and roleasing'mechanismf Figs. 7 and 8 are detail views of the blank supporting device. Figs. 9, i? 19 and 11 are detail views of the cylinder valve 1$ mechanism. 2G; TheQsbioct of my inveii'iion is to so improve the construc of machines for the manufacture of hollow. and especially glam that the numb-er i ma'iial operations m'ay be reduced and such operat ions ihnderod easier, so that the output of the Inn-- 251 chines'may be increased; and so thatsuch machines may be simpler, with the result um they will be less expensive to build and cheaper to maintain because of-decreased liability to get out of order, and to these ed as hereinafter specified and claimed. Tho belongs to tint class employ'mg s rs-.

volvihg table A onwhich are mounted five molds B,

which, by the rotation of the table, srosuccessivel'y i brought intoposition for, first, the lifting of the pressing bottom or blank into a mold and the reception of tho -molten'glan;rsocond, for position for the descent of the E mold follower'ringand the-plunger; third,

I p for position'fq'the descent of the blower head'an d m csivo the-batch of molten glass, End a stem in the form g. of s rodsth'at extends downward from said head. Be-

j Q n'oath each mold there is bolted to the underside 'oftho revolving taule, a bracket D made in one piece, which, at its 1 ,wer' horizontal end, has a liul". through which Q the blank stem passes and is guided, and adjacent to .suph hole on the underside of the bracket there is piv- 'btcd'a plate or dog E that is adapted to pass over the nd; yinvention consistsin the machine construct. '80;

' hole in the bracket, and is normally moved into posi tion.to do this by a spiral springl", the stop in the form of a pin or stud d on the underside of the bracket engaging the plate to restrain its movement by the spring. On the edge of its portion that overlies the hole in the lzracket, the plate has a semi-circular notch e of lea! radius than the radius ofthe lower end of the blank stem, the purpose oi which will hereinafter appear. It will be seen that when the stem of the blank is lifted to a position above said pivoted plate, it will rest upon and be supported .blLslid plate in its lifted position with the blank within the mold B above it. .To so lift the stem and the blank, the stem at one point in the revolution of the rotating table is. in'alinement vertically with a rod 9 of a piston G in a vertical cylinder H, to whilh cylinder air under procure is supplied, as will hereinafterbe described, for lifting the piston to accomplish 'the engsgarnent'ot its rod 9 with the blank stern and thereby lifting the latter.- Air under-pressure is likewise supplied to the cylinder to force its piston downward. The upper end of the piston-rod g is re duced in diameter so that when the blank Item has been lifted above the plate E, the latter may swing beneath the bottom of the blank stem and it is for this purpose that the notch s is provided in the plate E.

Preferablythe stern engaging portion of .the piston rod is vertically adjustable and for this purpose it may be in the iormpf a screw pin 5': bolt. The blank having been lifted, as hasiust-bssn described, the next step in the turning of tho tabls brihgs the new with the lifted blank therein beneath the pressing plunger and the follower ring. .-The pressing plunger 1 is carried by a piston} in a vertical cylinder K, which I prefer to call thomain cylinder, which is bolted to the frame of the machine. "021' the side of the main cylinder K there is a valve which'consists of a rotary disk L on s valve-scat M,

which vslve-Isea'thas two ports, m 9nd in that lead respectively to the top and bottom of the main cylinder, a third port m that leads to" an exhaust m and a fourth port m. from an air inlet m to supply pressure to the bottbmot'the cylinder to lift'tho piston therein. A cap or cover M -incloses the valve. Besides such inlet m the' valve chamber has a second air inlet in." which supplies sir constantly .thoroto and the air rotation oi the'valve to plat-c the exhaust port in -mu;- ceceion'into connnunieation with the two ports, at

and m which lead reuiwctively to the top and bottom of the t'ylinder. The other wgmontal port I by 5 the rotation of the valve, planes the portm in the valve aeat which leads to the bottom ot the cylinder, in communication with the air inlet port. m -in the valve seat. Hcrotoiore a valve-operating handle'lnul been applied directly to the stem of the rotating valve. This is objectionable, as it requires tolntiderable movement of the handle, whieh. of t'ourse, taken time and it is otherwise objectionable. 'lo obviate these objections 1 provide the valve stem with a crank arm N and pivotally connect such arm to a hand lever O pivoted eecentrically to the valve.

With this conetruction a short. motion of said operating lever in mammary, and the movement of the valve is easy and quick. 1- provide means for adjusting the swing oi the valve, so that a longer or idiom-r 29 movement thereof may be provided to regulate the opening of the An air prwonre may thus he eoonomimdt Such ,meanl for adjuating the swing. may, as shown, couaiat simply of two iwrews l mount,-
