' To all whom it may concerns" Be it known that "I, THOMAS C. DUFFIELn,
a citizen of the United States; residinginEL- mer, N ewJersey; have invented certain Im-- provements in Bottle-Molds, of which. the
ollowing is a-specification; s i
The main object/of my'invention is to pros vide abottle-mold by which: it shal'libe possi ble to blow what are technically Pknownnas narrow-neck?bottles+that 'is, bottles havingnecks of small; diameter v' relativelyto the diameter :of' theirzbodyiportionsi This i o-b j ect I attain as hereinafter set-forth, reference being had. to the accompanying drawings, in

mold-sections initheir open positions o'ccu iedz- ='whichioperates"the blank B, this latter being pteve'nte'd from turning relatively to-the base during the time that the neck of a bott eis being formed Fig. 3 isa planview'of my mold, :showing the dummyisections in their open positions and the neck and main: mold sections in their closed positions, the. bottom section of the moldibeinwinits inner position, 1 as when'the'body of thco'ttle isibeing-blo wna Fig. 4 is a side-elevation of the mold with-the parts occupying the positions showninFig. 3.. Fig. 5 is a vertical section taken on the line 5 5, Fig. 2; and Fig. 6 is a verticalgsection otthe?' mold, taken on the line 66, Figi3.
In carrying out my invention I provide" a 1 y C and G1 are so proportioned that hen in supporting structure-having a ireciprocable blank coacting with appara-tus forblowing; bottles by compressed air, which may be aof the general type shown and described'in my Patent No. 736,708, dated August-18,1903;. Cooperating with the blank I provide in the, present instance a pair of dummy sections and a pair of neckforminga. sections, which are-designed to receive a definite predeter minedcharge of molten glass. When-such charge hasbeen inserted, a vertically-moving plunger .is then entered into the? blank through the neck-sections, and this forces the glass up into said sections, causing it to assume the desired ,shapeunder the action of both the neck and r the dummy =secti'on's.
This plunger isnow removed and theblank allowed to drop, after which-the dummy sections areturned to their open positions and the bottom se" i ion ismoved into placelover the opening through :which the blank has to the moldan'd-the body of the bottle is J i blown, it being noted" that by means of the secondaryor dummy mold sec'tionsI am en-V abled to form'the neck and a portionof the shoulder 'of-aibot'tle having azneck of any desired dimensions casto thicknessof material, 'dlameter; and-lengths Moreover, the moldsections and neck-sections are so made that thesact-of 'closi-ngone pair of said mold-sections incidentally causes the closing of the neck-sections; and while. the mold-sections maybe opened'independently of said necksections these latter may be maintained 'lOCkGdiiIl theirclosed positions iridepend- In the -above drawings, -A re resents the pending from it atubular guide portion a, in
yineansofa set-screw a in the portion a. A suitable k'eyfway b isformed insaid blank for the reception: of the endof. said screw.
Carried by the. supporting structure A are .two pivot-pins a? and a fupon the first of whichare carriedorapivotally supported the two -partslor'sections G" and C of the main mold. It will be understood that-the said pin a is so-spaced from the openin in the supporting? structure, through which the blanknB operates, and that the two s ctions their .ClOSGdr-P'OSltiOIlS the .axisof the recess in'which thebottle is to be blown coincides with the line of motion of said blank. Proj acting upwardly from the top of the base of From;Figs..4 and 6 it. willbe seen that one of themain-mold sections .0 has a depending vflan e portion 'c, designed to engage the upc llyeprojecting flanged? of the su fpo'rting structure *w-henwthe former is moved to its j closedposition, the similar portion of the section- C being -zparti'ally :cut away to permit of war ently of the'dummy' and main mold sections. I
the supporting structure :AYis a flange or 001- 181 1a, concentric with the" opening in which the blank' B' m'ovesand cut away at one side to permit' of the entrance and removal of the bottom section E, which consists ofa disklike piece having-an operating-handle e, slid ably mounted in an Hundercut or dovetail groove in the supporting structure A.
.. sists of two sections hinged upon the pivot-pin ends of the two sections are provided with a.
- independently of the bottom section E,
tions, which together form what is known as illustrates "the hollow or recessed portion of both pairs of the sections C and C and D and the reception of the pivot-pin a an d in ad- I dition provide a handle f having a project- -'ing locking-bar f designed to engage with A the projecting end-Sc of a. rotary bar'cicarried pose hereinafter noted. 'pivot-pin a are pivotally mounted the two sections D and D of the dummy mold, as well ble locking-bar (1 having on one end a pro- Asshown best in Figs. 5 and 6, I provide a the lower faces-of the neck-sections F and F,
the entrance and removal of the bottom section E when the main mold sections are closed. A handle 0 is provided for the section 0, which latter is recessed, as indicated in dotted lines in Fig. 6, for the reception of by the section C and operated by means of a handle a. The two sections 0 and C are rerecessed to form the body, shoulder, and base of the neck of a finished bottle, and it will be seen from the-figures that the upper circular recess (indicated at 0 for a pur- Upon the second Said sections D and D are, moreover, respectively provided with handles (1 and d, the latter of which is carried upon a revolujecting portion (1 designed to engage a suit able recess in the section D. These two sec-.
the dummy mold, are recessed, so as to permit of the entrance of the blank B, their essential element, however, being the part d", which is designed to form the upper part of the shoulder and base of the neck of a bottle. The blank B fits up against the lower portion of this part d, as shown in Fig. 5, whlch also tllie blank for receiving the charge of molten g ass.
The neck-mold, as shown in Fig. 1, cona which are designed, when. in their'closed positions, to provide a mold for the neck and top of the bottle. In order that these sections may be brought to the necessary position, with their neck-forming recesses in line with the line of motion of the blank B and in the axis of the recesses formed by D, I provide semicylindrical recesses f, respectively, in the two sections F and F for the end f 3 of section F. This latter section is also provided with an operating-handle f circular projecting shoulder or collar f on which is designed to coact with the recesses in either the dummy or main mold. sections," so that when the two sections of either-0t said two molds are moved to their closed positiens their upperportions engage this 001- larf of the sections'of the neck-mold and turn said. sections upon the pivot-pin a thereby locking'themin a closed position as placed in the'hollow of the blank. The two sections D and D of the dummy mold are then turned on their pivot totheir closed position, thereby also closing the two sections F and F of the neck-mold, the various parts then occupying the positions shown in Fig. 2. The handle d is then given a partial turn, so as to bring its locking-arm (1 into engagement with the section D, and the handlef of the section F of the neck-mold is also swung onitspivot, so as to bring its portionf into locking engagement with the end f of the section F. A vertically-movable plunger of the wellknown form, as indicated at G in Fig. 4, is now forced through the neck-mold into the mass of glass within the hollow of the blank B, thereby forcing said glass upwardly out ofthe said blank and into the spaces surrounding said plunger and defined by the shoulder d of the dummy mold and the walls of the recess in the neck-mold. This plunger G is then withdrawn, the blank B is allowed to drop, and the two sections of the dummy mold are moved to their open positions, after which the two sections of the main mold are brought into their closed positions and locked, as shownin Fig. 3. The bottom section E is then moved inwardly by means of its handle 6, and suitable blowing apparatus is applied to the opening of the neck-mold, after which compressed ,air is admitted to said mold and the bottle blown in the well-known way. The main mold and neck-mold may now be opened and the finished bottle removed.
It will be seen that the blank serves to confine the charge of molten glass during the operation of forming the neck and upper portion of the shoulder of the bottle, while the dummy mold with the neck-mold serve to properly form the corresponding portions of the bottle when the plunger G forces the molten glass up and out of the blank B. As far as the construction of the dummy mold is concerned it is immaterial as to how its neck and shoulder portions are moved into and out of position, although I preferably form them as parts of a relatively large body of .metal, which in the present instance fits tightly around the blank when this is in its raised position.
By my invention I am enabled to thus provide' a relatively simple and easily-operated devicewhereby narrow-neck bottles may be blown by the use of compressed air, where hitherto it has only been possible to so manufacture what are known as "wide-mouthed bottles.
I claim as my invention v 1. The combination of a sup orting structure, a recessed blank movable t erein, means constructed to form the neck of a bottle, a bottom section for the mold movable in a line substantially at right anglesto the line of movement of the blank, a main mold independent of said neckforming means, and other means for forming the upper portion of the bottle, substantially as described.
2. The combination of a supporting structure, two pivot-pins thereon, a reciprocable blank movable between said pins, a dummy mold having itssections mounted upon one of the pins and designed to coact with the blank to form the upper portion of a bottle, and a main mold mounted upon the other pivot-pin designed to form the finished bottle, with a neck-mold having sections mounted upon one of said pins and having means whereby it may be locked to the second pin, substantially as described.
3.' The combination of a supporting structure, a dummy mold for forming a portion of a bottle and mounted on said structure, a blank and a plunger coacting with said dummy mold, a main mold, and a neck-mold, the parts of said neck-mold coacting with the parts of the dummy mold so as to be movedthereby to their closed positions by the act of closing the dummy mold, substantially as described.
v 4. A mold consisting of two pivotallymounted sections, a neck-mold also made in sections, with means whereby said first mold is made to coact with the neck-mold to move the sections of the latter to their closed positions when said first mold is closed, and means for locking the neck-mold to the pivot of one of the said mold-sections, substantially as described.
5. The combination of a supporting structure, a dummy mold and a main mold having their sections pivotally mounted thereon, and a neck-mold also having pivotallymounted sections, With a collar on one of the two members comprised by the dummy mold and the neck-mold, placed to engagethe other of said members to cause closing of the same when the other is moved to its closed position, with locking means on the neck-mold whereby it may be held to the spindle of one of the other mold-sections, substantially as described.
6. The combination of a supporting structure having an opening, a blank movable in said opening, two pivot-pins carried by the supporting structure, a dumm mold having sections recessed to receive t e blank and havin portions for tormin the upper'fportion 0 a bottle, a main mol recesse to orm the finished bottle, and a neck-mold for forming the upper portion of a bottle, said neckmold having means whereby it may belocked with its neck-forming recess in line with the line of motion of the blank, substantially as described.
