cured lt, one of the plates f bymeansof the 'boltf?, the lugs f3 upon the' platef holding thele'ver rmly'in position.. The said seg'- Vmental plates and the handle together constitute a lever.

The plunger D is secured to the lower end of the `plunger-rod, d. T he plunger-rod d is screwed into the plate d2, said plate having the slots d3 therein, in which are pivoted the lingers di. The upper ends of these fingers rest against the inclined facefof the nut d5, which' moves up and down on the threaded surface ofthe plunger-rod d; When thennt d5 is turned upon the plunger-mdd so -aslto move the n ut d5 downward between the upper ends of the nge'rs d4, said upper ends 'are *forced out and the lower ends d6 of said lingers are forced together under the shoulder D' of .the plunger, gripping it and holding-it firmly' in place' against the plate d2. Guide-.rods 0F, secured to the plate d2, slide in the guides ci as the plunger-rod moves up and down and holds the plunger against any 'side motion; The guides c4 are formed at the outer ends ofthe arms c5, which in turn are bolted to the frame c.

. The plunger-rod d moves in the guide c?,

formed at .the outer end of the extension-c3 of the frame c. Pivoted to the upper ends of saidgnide ce at the point c" are the two levers g, one at each side thereof, To 'the outer ends of said levers g at the points 'g2 are pivoted the-two levers g', which at their lower ends are pivoted tothe block d?, said blockY being securedA to the plunger-rod t2.

Links f4 are pivoted to'tlieinner sides of the being pivoted'at their other ends to the lpiv` otalpoint g2 of the levers g and g'. It will thus be seen that as the lever f is moved in `thedirection of the arrow, Fig. 2, the Vplates f will rock uponthe shaft o. and byrneaus of 'the links f4 will drawthe point g2 of t-lic levers segmentalplates f, as at f5, said links also l taneously with the other, yboth toggles'act v Esimultaneously upon the the lever f is operated.

Coiled springs h surround these rods h3, being interposed l s between the plates h and h2, and hold the jbymeans of the bifurcated link j.

spring-plate firmly against the top of the mold when the plunger is being forced therein.

The plate h2 surrounds the plunger-rod d and is free to slide thereon, being held in adjustment by means of the nuts h and 717, which move u on the threadedsurface of the rod d, the nu s h6 and k7 being, respectively, above and beneath the plate h2. v

The revolving table (L2 has the bevel-gear i eitherformedl integral therewith or attached thereto, said gear-wheel being secured beneaththe table. A bevel-pinion fi', mounted upon the horizontal shaft i2, meshes into the bevel-gear t'. The shaft i* revolves in the bearings t, formed upon the outside of the hollow post A rod j, carrying at its lower end the yoke j', is pivotally attached at one end of levers The levers j* (only one of which is shown in the drawings) are pivoted at about their centers to the standard C, one at each side thereof, at

the points C', the other ends of these levers being bifu'rcat'ed, as shown in dotted lines at y". Piusjfs are secured to the lugs j upon the plates f, said pins entering these bifurcated ends j* of the levers j2.

Secured to the horizontal shaft 'i2 is the ratchet-wheel i, Fig. 4. Pawls i4 and 5 are pivoted to the yoke j', said yoke encircling s the shaft 'i2 and moving up and down thereon.

The pawl t* is pivoted to the yoke j' at the point 'is and hangs downwardly therefrom in such a. position that its free end may entera tooth of the ratchet-wheel ses the yoke descends and revolve the ratchet-wheel and its shaft 112 therewith. The pawl 1' is pivoted to the lower end of the yoke j' at the point 7, its free end extending up in such a position as to engage the teeth of the ratchet-wheel as the `voke ,7' moves up.

A s ring-actuated pawl k is pivoted to the 'arm k said arm extending out from the post a', eitherbein g att-ached thereto or forming a part thereof. The spring k2, which actuates the pawl k, is bolted to the arm k'.

The lip k of the pawl enters aslot or notch i* in the gear-wheel i, locking said gear,` and conse quently the table a2, from being carried too far around by its momentum when the table is revolved as the plunger recedes from the mold.

The number of notches in the gear-wheel corresponds to the number c mo- La used upon the table. A lug la* extentie be ond the lip k' of the lever k, angl a pin or pT ,J-ection kf is 4 ing in the direction of the arrow.

in such position upon the yoke j' as to engage said lug or projection k and release the lip k3 from the slot or notch 'is as the yoke descends and before the pawl i* engages with the ratchet-wheel i3 to revolve the same and.

rotate the table to carry one of the molds beneath the plunger.

I will now proceed to describe the mold and the several parts connected therewith.

In the operations df pressing and blowing an article of glassware itis necessary to havey ,plish by means of a combination-mold, one

mold serving for both the purposes of pressing and blowing.

As previously explained, any number of molds may bevused upon the table; but I find in practice that five molds work most perfectly.

As the molds and their attachments are all alike, I will describe one, such description applying to each.

My mold B is atwo-part mold composed of the two halves b b', as will be readily'vunderstood by ,consulting Fig. 3, these two halves being hinged together at b, as shown, and locked together atthe front by a new and novel construction of 'mold-locking device, which will be more fully hereinafter described. These two halves when closed and locked serve the purpose of a blow-mold in connection with'the ring b3 and the false bottom composed of the two halves b and b.

In Fig. 2 I have shown the parts of the mold lettered B3 as being in the positions they would assume during the blowing operation with the finished article therein. 1n realty, although the parts are shown in proper relation 'with each other for the position of the mold, the finished article would have been removed -from said mold ,when it was in thc position B2 shown in Fig. 3, the table revolv- The ring b3 may of course be made of any design to suit the shape desired for the top rim of the article to be formed. In the' present instance the interior of said ring is threaded to suit the top of the fruit-jar. 'This ring is formed with the upper fiange 'be and the neck b, said n eck fitting into the countersunk portion bg, formed in the top of the mold. This ring is of course formed with the central opening Z1',-

This I accomlIO . '5 sleeve bei'ngof 'such a shape at its as to form the walls of the mold in whichthe' '.zo its outer surface.

The aforementioned hanger l is formed U- shaped-and isbolted Aat` its upper end to the under' slide' of the-platea.

'Slidingup'onl the rod Z is the-sleeje m, said pper end blank is pressed when the 'sleeve isv liftedup into the blow-mold. As shown inFig. 2;lthe

I mold lettered Bis arranged for the pressing zo operation, the pressed blank, being shown f therein. Thelpress-mold is formed of the appr portion of the sleeve m', therod l, and the ring b. The v#top forms the bottom of said press-mold, lthe upper portion .of sleeve m forms the sides of said mold, and the lower` .portion ofthe neck 4of.' rin-g b shapes the neck of the jar as it appear. in the -iinlshed article, which 'in' the vcase illustr ted vhas 'screw-threads' upon The "leeve mi has cast thereon at its lower l end the lugs m; and m. '.The lug m' serves as -a bearing for the-roller .m3, vwhich rides upon the' upper face of the cam-shaped ringl 25,97. This cam -shapod ring 'n surroundsthe post a and is supported 'by the posts fn', n2,

and n. This cam-shaped ring lnl is formed of the 4inclined portion n* and' the horizontal rtion 'rr". As the'plate or table a revolves,

3o carrying the molds and its accessories there.v

with, the rollers 'm3 of the sleeve m ride upon rho upper faceof the .ring n. The highest point of the incline n* is directly beneath the radialline drawn through the point of` the 3,5I plunger D and the center of rotation. It will thus .be seen that as the roller m rides up the inclined` face ofthe portion 'n of ring linthe sleeve m will be carried up into'the mold B,

end whjen it has reached its' highest point it 4o is in proper position foro thevplungento descend therein and form the blank. A pin l2 passes through the rod -l and the slots m* out in opposite sides of the sleeve 'm, said pin sliding in the slots m as the sleeve moves up 4'5 and down on the rod Z and prevents the sleeve Recesses mi are formed at the bottom of said slots m, in

m from rotating upon the rod l.

which the pin l engages when the sleeve m has been carried to its highestl point, the 5o sleevebeing partially revolved byrthe nat- -ural drag of the roller 'mil upon the ring n -until/the pin l?y engages in said recess1 m5 A stop n" is attached to the post n', being.

apart thereof, and is of such shape that the portion .na at the upper end thereof is in the path of 'the lug m2 of sleeve m. When the lug 'm2 comes in contact with the stop ne, the sleeve m is revolved in a direction opposite to that occasionedby the drag of the roller lol upon thering n and the pin P isdisengaged from therecesses m5. The sleeve then drops by its own weight until the roller 'ms strikes the horizontal portion nf of the ring fn. Y

The molds B B B2, &c., restupon the botv 65 tom-ring a, said ring fitting'into the table a',

-itstopisurface being flush with the' top surf faceof said table... This'bottoml ring as is surface of the rod lY for'med with the dovetail portion a, which slots 1 of plates ando?. The short arms 0 `of levers o extend substantially at right angies to the armee. Grooves mtare cut in the outer face of sleeve in, at the upper end of whichisthe recessml; f'

Bolted or otherwise secured to the 'upright (l is-the arm P,-having at its outer endgthe guide isthe blowpipe Projecting up'- wardly from the guide-p .is the arm p', at the upper end of which is formeda .bearing for pipe E -isthe fork e, in which'the in e' of the lever p is journaled. A spring surrounds theupperg'end of pipe E,being interposed between the fork e of pipe E and the uppel` face of guide p. This spring normally holds the shoulder Eof pipe E up against the lower face ofthe guide p. A rod p3 slides in the said rod having the ring p keyed near its upper endand a spring p6 surrounding said rod and inte osed between said rin and guide. Pivoted to the lower end of rod p is the hook p". The hooked ortion p8 thereof projects beneath the plate of the plunger-rod d. The rod ps may be jointed', as at p9, to admit ofa lower section of said rod. Y

At the lower end of the blowppe E is the ange q, which rests upon the top face of ring b3 during the blowing operation, the reduced forming a tight Yjoint therewith..

` The blowpipe E is formed hollow throughout the greater portion ot its length (see Fig. 6) and has the hole E2 drilled therein. A boss r is cast upon the outer surface of guide-'10, said boss. being formed with the hole rr' therein. A ipe r is threaded into .the boss r, said pipe be ng in connecton'with an air pumpor reservoir, as may be desired'. When the in contact with the ring ba of the mold, the hole E* comes in line with the hole r of boss fr and the Yair passes from the pump or reservoir through pipe 'r2 and hole E2 to the blow- -pipe E, and thence into the mold B', filling the blank therein andformiug thenished article. c

To facilitate 'the operation of handling .the

of anew and novel construction, the main projects above itsupper face. The two parts their upper endswhichengage' pins Zin the.

To the forward'end of the part b of the mold l cast the lug s, through which the pin s passes. A latch T, composed of the upper and lower platesz, and t' and connected by the web t", is mounted to swingen the pin s', journaled in the lng s. An eccentric-pins2 passes through holes formed therefor in the free ends of the links t and t'. The eccentricpin s extends above the link `Land a lever yv is keyed. thereto. The said eccentric-pin s2 is freely removable by means of the leveror handle v.. A lug s, having the curved face s4 and the recess S5 therein, is cast to the part b' of the mold and corresponds in general to the lug s of part b of said mold. Threaded rods w and w are attached tothe mold in such positions that handles may be placed thereon, so that they may be readilygrasped bythe operator and the molds opened and closed thereby.v

In Fig. 1l 1 have shown a modified form of my invention in which the eccentric-pin instead` of passing through openings formed in the free ends of the links t 't' passes throughthe opposite ends of the latch. The device operates in the-same manner as before, thev centering-pin s' in this case engaging with the recess S5.

Suppose the parts to be in the position shown in Fig. 3, referring to any One 0f the molds, such as B', said mold being closed. To open the mold', the operator grasps the lever v'and moves it in the direction ot' the ar; row. By so doing the short side of the eccentric-pin (shown in dotted lines) is turned toward the face s* of the lug s3, when the lock may be easily swung out to the position shown in mold lettered Bz and the mold opened. The faces4 of lug 5*" is an arc of a circle whose cent-er will be the center of pin s' when the molds are closed. This Vlock may of course be employed with anyform of mold, whether a press or blow mold, and I do not wish to limit myself to its use in connection with the mold illustrated.

The molds are placed in ovens to be heated before they are used, and the eccentric-pin is removed before the-mold is introduced into the oven in order that said pin may not be subjected to the action of the heat and caused to expand. It the pin was permitted to re-- main in the latch and the eccentric-pin was for any reason turned so as to lock the parts of the mold when in the oven, the expansion would cause said pin to bend or the lugs on the latches would break under the strain. By having the eccentric-pin freely removable and yet capable of locking and unlocking the mold without removal is an importantvfeature, as it permits of the ready withdrawal of the pin when the mold is inserted in the oven, and yet avoids the necessity ot removing the pin each time the mold is opened.

In the operation of my invention the opereter first drops the proper amount of glass into the mold which stands one-tenth of a mold being the one which will come next beneath the plunger as the lever f is moved in the direction. of the arrow, Fig. 2. The roller m3 has previously mi, :ed up the inclined sun face n4 of the camring n and the sleeve nzv moved up into the mold, the ring b3 of course being in position at the top of the mold. llaving dropped the proper amount of glass in the' mold, the operator grasps the lever f and draws it toward him, said lever moving. in the direction indicated by the arrow. As the lever is thus moved the plates f will move upon the rock-shaft c' in the are of a circle. The pins jf', projecting into the space between the jaws j* of lever ver, depressing the opposite end thereof, to which the ,rod j is attached, through the moans of link js. The rod j being thus depressed will carry the yoke gj' downwardly therewith. The pin kil, pressing against the lug 7o* of lever .7.5, acts to remove the lip 7c3 from engagement with the gear-Wheel and unlock said gearwheel and table, so that said table may be revolved. By the time the lever 7c has been depressed suiliciently to unlock the table the pawl t" enters a tooth of the ratchet-.wheel i, revolvingthe same, and, through the shaft i2, ,the bevel-pinion t' and bevel. gear-wheel The Ytable is thus revolved sufficiently to bring the mold directly beneath the plunger. As the rock-shaft is further revolved the pin j5 passes from between the prongs ,7" of lever 7'2 andldoes not further move said lever or its adjuncts. nAslthe lever is moved and the platesv f are partially revolved therewith the levers f4, connected thereto, act to draw the common point g2 of levers g and` g'downwardlyaanin toward the standard C. In so doing the point d descends and the plunger is pressed into the mold. Asthe plunger descends the taper of said plunger acts to properly center the mold, if it should be for any reason out of line. After the pressing open ation has been completed the lever is moved upwardly or in a direction opposite to that indicated by the arrow, and the parts again assume the position shown in l1`ig.2, the pin ,7'5 having entered the bifurcated endj of lever .i2 and raising the rod j and yoke] thereon. As the yoke j is thus raised the pawl if enters a tooth of the ratchet-wheel is, partially revolving said ratchet-wheel,and,in asimilar manner. to that previously described, further revolves 'the table a2 one-tenth of s revolution until the plunger again stands elevated half-way between two of the molds. This operation is 'continued and the blanks are pressed one after the other. As the plunger recedes and the table 'revolves the lug m2 of sleeve 'm strikes the stop n, and the pip i2 is released. -from the recessm. AAt the'same time the cam-ring. AAs the sleeve drops the short revolution to the right of the plunger, said j, will lift said end of lej roller mleaves the inclined portion n of camring n, and the sleeve m drops'until the roller m3 strikes the horizontal port-ion 'nf of said..

hole E2 of blowpipe E is brought into line with opening fr',l p When'the flange-q has reached its seat, the'compressed' airenters through th'e pipe fr? and theblank is blown outto the shape of the mold. As the plunger recedes and the plate d2 nieves up therewith the tension uponlever I is released andthe spring e2 acts to lift the b owpipe E and the flange q from coul` tactwith the mold, andthe air-pressure is'cut off as the lhole E2 recedes. from line with the .opening 'r'. :Asthe blQWPipe recedes the op-h erator revolves the ring b backwardlyen the threads .formed upon the neck of the jar, in

order to release the ring from said thread.v4 'The lever v is then grasped,l the moldlun-- locked and-subsequently opened in' the usual manner, and the articleis removed. I.

`I willnow-proceed to give a more l descriptionpof the different positions assumed by the several parts of the mold, dac., referringmore especially to Figs. 1, 2, and 3.

roller 'ma is just ready to start up the incline n4, the'platesband b, which constitute the bottom for the blow-mold, still being in position. The mold isof course closed and locked and the ring-bl in place. As the 1 machine goes through another complete operation the moved part way upthe incline. The plates T24 b", forming 1 4to moveup' into the mold a'distance correspending to the ascent of roller m. As the table further revolves until it 'reaches the po-` sition shown at B the, partswilltake thepositions shown in Fig. 2, except that whenthe settimav Fig.' 2 the mold B? is so situated that the..

the bottom 'of the blow mold, 'have been withdrawn, allowingthe sleeve m' occasioned by th'e friction of said roller mov- Vlng upon the cam-ring, will allow the pin ll to enter Vthe recess 'm5 and .hold the sleeve m iirrnlyup into the mold."- The plunger, hereblank, as shown in the mold B, Fig. '2. As the plunger is raised the table moves around and the lug 'm2, coming into contact with the stop '0.8, acts to revolve the sleeve m in a direction opposite to that-caused by the drag of the roller m8 upon the cam-ring and the the roller at thesame time reaches the end of the inclined portion-n4 of ring 'n' the-sleeve Z di'ops, leaving-the blank suspended in. the moldas previously described.; `As the sleeve drops the platesy b4 and b5 are' forced in,sa.s previously described, forming the bottom for the .blow-mold. The table then further revolves until the mold reaches the position as vshown at B', Figs. 41I and 3,where the blowing operation -is completed, as previously deiscribed. v.As the tableis further revolved the ring b9' is' reinoved by turning said ring backward upon the threads formed around the neck of the' jar. In .this manner I am enabled to rform an article .with a perfect thread duringthepressing operation. The; mold is V. thenunlocked and the jar removed. By '.rny methodV of pressing the threads of moving said ring by revolving the'samebackward upon said threads I form a uniform thread free from fins.

By this construction the one side, as it is -ree to do. when the blank is,V merely' suspended from the neck,-as is the '.-usual method.' I am also enabled to form an .,article'fvth' a smooth neck-that is to say, with no bead or thread to hold the blank in place, 'as is necessary when the blank is merely suspended from the neck, as previouslyfexplained.
