Be it known that. l, WARM): ii). Gmsrn,

a citizen of the United States, residing at Brideton, in the county of {lumberland and tate ot' New Jersey, have invented a new and useful improvement in Machines for Making Bottles. Etc., of which the following is a specification.

rlhis invention relates particularly to Inzichines for making bottles, or similar continuel-5,. which lare provided within the4 mouth-portion with an iiiiiternel screw thread; and the primary object ot' the invention is to provide an improved machine for the purpose indica-ted, which is capable of large output, which reduces VWastege to a. minimum, and which isv economicel'in operation.

The invention 'is illustrated, its preferred embodiment, in the accompanying drawingsa in Whiclimy 'Y 'Figure i represents e broken plan View of n, bottle-making machine embodying' the invention; Fig'. 2, e. broken vertical sectional View showing n Jfriction clutch device with which the inainlrehpiuions are equipped; Fig. il. n broken elevational View of the i1nproved uuiehine; Fig. i, a broken vertical sectional View taken at the bu'ble-blowingy station; Fig. 5. a broken plan sectional View illustrating the manner in which the molds are mounted on the intermittentlyeotuated rotar;7 table; and Fig. il, e vertical sectional view oi' the mechanism shown in Fig. 5.

lt muy be stated preliminurily that it bottleiuziliing' machine of the general type illustrated is known, such mnehine involv ing' the use of e rotary mold-carrier having Y invertible molds mounted on the carrier. The present invention relates part-ieulznrlvvY to the provision et means in connection with such machine wherebiy bottles having internally threaded mouth portions may be gu'oduced by ineens of such a. machine. Sei--4 tain ot' the tentures of improvement are adapted, however, for use in connec-tiim with bOttlemeking mecl'iines generally.

Also, it may be stated preliminerily that in the construction heitein illustrated the rotery mold-carrer is equipped vwith revoluble .inolihsupports which serve to invert the molds und then right them the molds are carried in their orbit; e pinion-equipped i922. serial no. nettes;

threaded mandrel is carried with esch moldg and a pair of yieldingly-mounted 65 curved recits are employed for raising end lowering the inendreis;v seristim, one of seid reeks being concave and the other one being convex, the racks being located on opposite sides ot the path of the pinion's with Whieh eo the mandi-els are equipped. At, the inter mediate' station shown in Fig, l, the glosschurging operation is performed after the mandrel lies been elevated; end et the next' station the bubble-blowing operation is per en formed after the mandrel has been lowered. s At the intermediate station a blow-head is employed to force the glass down into the lower portion of the mold so that it will form properly about the threaded tip 'of the 70 mandrel in the neck portion o the mold.

Each, mandrel has a threaded stem which works' through a. nut. which is mounted in coaxial alignment with the mold.

Itv muy be added at this point that the bottle-blanks or psrisons, are formed in the machine illustrated in the accompanying drawings; that the molds are, in the operation ot' the machine, inverted and opened and the parisons or bottle-blanks are transse ferred to e blowing machine; and that the final operation oi blowing the bottles is performed in the machine last referred to, no illustrationV oi' such machine being required for the purpose of the description of the se inesent. invention.

In the embodiment of the invention illustrat-ed, A 'represents the base ot u treme trom which rises u stationery shaft or col uninlg' B, u 'rotary mold-carrier having oe revoluhly mounted thereon a series oi' moldsupports i3upon which ure mounted molds B2; Bn large ire-.ir through the medium of which the nioli'l-eurrier i3 is rotated, so that the molds will he carried in an :.innuler e6 puth or orhit; il sind C' Stationery Canis which serve io close und open the molds; D, e stationery bevel-geur segnn'uit which serves to rotate. the mold supports :ind invert and then right the molds os they'ure carried me through their orbit.; E, u threaded tubular mandrel nssoeieted with eeeh mold, each mandrel being; equipped :it its projecting lower end with n geur-element or pinion ll;

F, :i yieldingly mounted concave rack which m5 serves to elevate the mendrels, in turn, es

1 as en axis about which the mold-table B,

actuated by the eear B, turns; and the column A. serves also to support certain mechonisms, including the blowfhead which is employed for blowin the glass down into the mold so'that it wi l form properly about the tip of the mandrel in theneck portion of the mold. The blow-head H employed for this purpose is of theusnal construction, and operates in the usual manner.

The mold-table isl given an intermittent or step-by-step n iovement` in any desired manner. The mold-cerrying means comprises the table B and the series supports B arranged thereon. ech moldsupport comprises a hollow trnnnion or gudgeon l and a disk or iaceplate 1 formed integrally therewith. The hollow trunnion 1 is jonrneled in a dividedbearing-box 2 which is securely fastened to the table B.

Each mold B2 comprises a pair of main mold sections 3 and a pair of ring-mold sections 3, These sections meet in a vertical plane and are provided with arms 3b and 3,respectively, which are connected ai their inner ends with a `pivot Al carried by lugs 4 which project from the faceplate 1". Thus, the mold sections are capable ggf separating at a plane containing the axi of the mold.

The threaded mandrel or plonger E, associated with each mold, works in a nut 5 which is rigidly secured to a bracket 5, the bracket 5'" being rigidly mounted on the faceplate oi l the mold-sn port B. The bracket 5 comfprises a tabu ar member 5l carried by a shank 5: and a pair of strong studs 'or bolts 5d which project. `from the face-plate of 4the mold-support B1. The .shank 5 of the hrm-kel is equipped with loops or rings 5 which are mounted on the laterally projecting studs 5d. Thetubnlor portion 5" of the bracket is thus stannchly supported on the studs 5* and may be adjusted thereolniif desired. Any suitable seem-imgr means` (not shown) may be e ploycd. The tubular por- Y tion 5" of the bracket is. located directly below the mold and is provided at its upper portion with o. peripheral flange 5f which interlocks with dances with which the ring-sections 3'* of the mold are provided. The not 5 has a portion which progects into the tubolari' pass into the chamber 6 during the bubble of mold! member 5* and secured by bolts (not shown) to the tubular member 5b.

Above the not 5 is a space or chamber 6. The mandrel E extends through this chamber. It has a tip portion T which is provided with a thread T which serves to form a thread within the mouth of the bottle. The tip portion of the mandrel has a reduced tubular shank within the Yhollow shaft which forms the mainv shonlr 7 of the mandrel. The shank 7 is externally threaded-and engages the nut 5. The pitch of the thread on the shank 7 corresponds with the pitch of the thread 7 at the `tip of the mandrel. The hollow mandrel ti 7 is provided with laterallyopenmgorltic'es 7d adapted to permitan to blowing operationl The opper portion o the threaded shank is provided with a lateral stud 8 which is adapted to engage an inwardly-projecting stud il which extends into the upper portion of the chamber 6, and.l thus limit the upward movement of the mandrel. gage a 'stud l0 which. projects upwardly from the nut 5, and thus limit the downward movement of the mandrel.;

The pinion E of each mandrel E is frichas a flange 5g which l which is fitted securely The stud 8 is also adapted to en-k tionally mounted on the lower end of the mandrel-shank 7", as will be clearly onderstood from Fig. 2. 1 The purpose is to pern mit the pinion to slip or turn with r lation to the mandrel after the mandrel has been raised or lowered 'by the rech. ln the'illnstration given, the shank 'if or each mandrel is provided wlth a reduced lower end portion l1 encircled by sections ll"M of a cone winch engage the interior/conical surface il oi' the Lpinion E. The cone-sections 1l are vieldingly held in gripping position by a ci coil springll whi is interposed between the cone sections and a not lid which is mounted on the reduced end'll of theshank of the mandrel. ln practice7 the racks are made somewhat longer than would be ref quired to elevateor lower theumandrels, .and provision for slippage of thepinions, that is,

rotation ofy the pmions without further movement of the `nnmdrels7 is made. The

friction deviceshown answers-the purpose admirably, but .any othersnitable connection The rac is are preferably mounted on yieldinglyfheld.. bel -cranli members., The

purpose is to permlt ay suihcient yielding of the rack to insure the pinion. comingv properly avoidingr in case the end stril-ze the Aend'of a tooth ofv the gear-segment or rack.

at points 12?'. The bell-.crank members i2 yfurther have vertical pivot portions l2 jourried by the standard orl bracket 13, end ere equipped with nuts l2 which serveto iidjust the' tension of springs l5 which ure confined between the lugs 1li and the arms The chamber 6 shown in 12". Thus the springs l5 serve to hold the reclrF yieldingly'in the position shown in Fig. l.

In a similar manner, bell-crank members 16, equipped with springs 16, serve to hold the rack Ff yieldin y in the positionI shown in Fig. l. The be l-creiilr members 16 are mounted on-a bracket or standard 17 carried by the base of the frame.

As will be understood from Figs. l, 5 and, 6, the mold seetionsv are opened and closed through the medium of a plunger 18 which extends through the hollov7 truniiion l. oi the mold support, the other end or" the plunger being connected', by links 19, with the mold sections. Each plunger 18 isequpped et its inner' or rear end with e oem roller idg;- end the movements of the plunger :ire controlled bythe cams C and C shown in Fig. l.

On the hollow trunnion l of each mold 'support is secured a bevel gear 20. v'lheee bearing-box may be .suoli es to cause the' bearing-box to ri the trunnion of the inold-support su eiently to maintain the mold iii its upright position during the pessege of the mold from one station to siiother. Any suitable looking devices may be employed for releasably looking tlie inolds in upright position,4 so that tney will be properly maintained in such position during their travel in the upright position.

ig. l communi- Cates through e central 'passage 6 with the neck portion of the mold cavity.. Thus when the mandrel is retracted air mayA pass from the bubble-blower into the cavity in the glass and blow the glass to Complete psrisoii form. The bubble bloiv-heed G shown in Fig.

4- eomprises a pipe 2l equipped with s veial tit-el hoe( on which is swiveled e ver tical tip A depending stem 24; carries the device G, this stem being equipped with a piston :35 Working in e cylinder 26. The

blow-heed G is elevated by pneumatic pressure. The blovvdiesd rises above the position shown in Fig. and is then depressedv by the mandrel, the tip portion 23 oi the device rotating with the mandrel.

tion is permitted by a ball hearing The pneumatic pressure which raises the pistou' This sc- 25 is suiioiently light to enable the blow-'1* head to be depressed by the mandrel, esthe' f mandrel descends,'until the stud 8 engeges the stop i0. The portion S21-3 of the device G is provided with n bevel tip 28 .vl'iieh is adapted to engage e. conical recess 28 with which the tubular mandrel shank is pro` vided et its lower end as shown in Fig. 2. l'

The operation of the improved machine may be stated brieiiy iis follows:

The mold-table B is given an intermite tent movement of rotation in the usuelv manner, the rotation being effected through the medium of the large gear B3. Asthe molds are carried pest the concave rock l?, the mandrel pinions travel along the ruck and cause the meudrels to be elevated. Thus, the niendrels occupy the elevated poA sition when they -reecli toe. glasschargingl station, which is the intermediate stationv At this point, the operzishown in Fig. l. tion of introducing the inetelf oir-molten glass, is performed, e funnel if being' em-` i; desired to facilitate this opere-A 'llie gloss is severed by ineens of si,

The improved machine operates in the same automatic manner as do machines of this type employed for making bottles heving pla-in, or Unthreaded interior mouth- `the proper meshing of the mandrel-gear with the rack, prevent jamming, and consef' quent breakage," and make it unnecessary to employ greet accuracy in the racks es to length and number of teeth7 care being teken to insure suilicient turning oi the inendrels, however. While the improved devices are 'shown applied to e machine equipped with inverti'ble molds, the inven tion is not limited to use with the invertihle mold ty of machine.

The igdiegoing detailed description `hos been given for clearness of understanding only and no unnecessary limitations should he understood therefrom, it heilig the in tentgto claim the invention as fully as possible in View ol the prior art.
