MACHINE FOR FINISHING GLSSWARE.

SPECIFICATION forming part of Letters Patent No. 648,272, dated April 24, 1900.

Application filed August 26 1899. Serial No. 728,623. (No model.)` i

To @ZZ whom it may concern,.-

Be it known that I, CHARLES LENG, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have inventednew and useful Improvements in Machines for Finishing Glassware, of which the following is a specification.

This invention is a machine for finishing the necks of bottles and other glass articles, and relates more particularly to certain improvements over the machines patented to myself and C. F. Leng Marc h 18, 1890, No. 423,482, land to myself May 20, 1890, No.. 428,214. In the patented machines just re ferred to two shafts, one Within the other, rotate in opposite directions, one carrying 4a former for the interior of the bottle-neck and the other carrying dies for forming the neck exterior. The range of said machines is limited, as the inner and outer formers or dies are not adjustable longitudinally with relation to each other, and such adjustment is one of the improvements embodied in my present invention. A

Further improvements are in the manner of supporting and 'adjusting the outer dies and in the means for throwing the machine in and The invention also includes improved means for grooving the interior of the bottleneck.

Other advantages and improvements will `become apparent as the nature of the invention is developed by the following speciiication, the claims appended thereto, and bythe accompanying drawings, in Which-- Figure 1 is a side elevation of my'improved machine, portions thereof being broken away and other portions shown in section. Fig. 2 is a longitudinal sectional view taken at right angles to the neck-forming mechanism shown in Fig. 1. Figs. 3 and 4 arecross-sectional views on lines 3 3 and 4 4, respectively, of Fig. 2. Figs. 5 and G are longitudinal sectional views, taken at right angles to each other, of an adaptation ofthe machine for forming an interiorgroove in the bottle-neck. Fig. 7 is a cross-sectional view on line 7 7 of Fig. 5. Fig. 8 is a face view of the formingmachine shown in'Figs. 1 and 2, the base be- 5o ing shown -in section. Fig. 9 is asectional view on line 9 9 of 1.

l. is a base supported on legs 2, and resting on the base is bed-frame 3 of the machine, from which Arise bearing-posts 5,and jour- 55 naled in these posts are shafts 6 and 7, o'ne within the other, and carrying, respectively, pulleys 6 and 7 for driving the machine'. Shaft 6 is threaded at the inner end, and shaft 7, extending through shaft 6, is slotted at its 6o innerd end at 8.

Uniting with the threaded en d of shaft 6 is chuck-head 9, depressed longitudinally on opposite sides of its exterior at 9', and pivoted at 10 in these depressions are arms 11, which 65 at one end are outwardiydeiiected at 12 to operatively engage cone-collar 13, slidable on chuck 9. The opposite ends of said arms eX- tend 'beyond the corresponding end of th'e chuck and carry dies 14. The latter arepiv.- 7o oted between their ends at 14' to said arms, and the desired=angle at which the dies work is secured and maintained by setrs'crews 15, working through the arms and, locked by nuts 15'. The inner faces of .the dies are shaped 75 to give the bottle-neck exterior the requisite form, which may be changed and varied as vdesired by substituting diderent dies.

Fitting the bore of chuck 9 is bushing 16, adjustable longitudinally and held by set- 89 screw 17. l

18 is a short shaft rotatable in the bushing and peripherally grooved at 18' to receive pin 19, which holds it against longitudinal play. One extremity of the shaft is attened at 2O 85 to enter slot 8 of shaft 7, andV the shaft is flanged at 21 to fit a corresponding depression in the end of bushing 16, and beyond the flange is integral inner die or 'forming plug 22, which enters the bottle-neck and shapes 9o the interior thereof, said plug being flattened on opposite sides to permit egress of air from the bottle during the forming operation.

'Integral with the extremity of bushing 16 is transverse plate 23, the sides of which are 95 almost intersected by flange 21, withwhich said plate alines, and said sideso'f the plate are also substantially coincident with the inner ends of dies 14. The plate has greater length than width, and hcncehas considervableprojection at right angles todies 1 4, as

shown in Fig. 4. Y .Y v f Slidableon bedframe 3 is carriage 24, and; vertically adjustable in the-'upright members; of the carriage are racks 26, having Vshaped notches to receive handle 27 of bottle-holder 28, the racks being clamped in desired adjustment by screws 29. j

. 30 is a bellf'crank lever fulcrumed to -the carriage at 31 and adjustably cf, ,'e'cted at its lower end to reach-rod 32, whi nl. connects with stem 33' of fork 33, which embraces conevcollar '13, whereby the latter is-'moved to acf tuate arms 11. Carriage 24 maybe moved toward Aandraway, from the forming mechanism, as circumstances may require, andis se-v cured in position by clamping-plate 34 and boltr34'. In operation the bottle-holder is placed in position shown in Figfl, remaining all the while in the grasp of the operator at `about points X, with die-plug 22 entered in the bottle-neck, dies 14 being held away by centrifugal actionI until closed onto the neck by cone 13, the inner and outer dies having c onstant rapid rotation inopposite directions.

Lever 3() is -then drawn up by one hand of thev operator without releasing handle 27 of the Vbottle-holder, thereby moving cone 13 against the deflected ends l2 of arms 11 andclosing dies 14 on "the exterior'of the bottle-neck, as seen in' Fig.'.2. With the inner ando'uter dies rotating oppositely ,the bottle remains still and its neck is quicklylgivenits inte-` rior and exterior form. The extremity of the -`neck bears against revolving plate 23, which Y smooths and finishes it, preventing fins` vor other Aroughness from remaining thereon.k Then theoperation is completed, lever 30 `is simply released, and the centrifugal ,action of dies l4-.throws them clear ofthe bottle,

and the latter is quickly withdrawn and another inserted by manipulation of thel bottleholder. y t

35 is an elevated tankhavingtwo compartments, one for oil and the other forsalt'water, whichdrip from a common spi got"36onto` the dies, keeping them in proper condition for finishing and polishingthe glass.

V52is a pipel which emits a blast. 4tfai tldies, preventing overheating." In Figs 5, 6, and 7 -I show an adaptation'fof the machine for forming the bottle-neck with an interior groove. When the salme is tov be used, bushing 16 and shaft 18 are Tremoved from chuck 9 and bushing 37 inserted and sej cured in proper longitudinal adjustment by set-sere w 17. Rotatable jin bushing 3'iiissghaft slotted longitudinally at 39 and at its rear end flattened at 38 to enter slot 8 of shaft 7. Said shaft is formed at the outer end with circular head 40, having a continuous peripheral groove to receive screws 37', entering terior as described of former22.

from facing-plate 37- of bushing 37, whereby shaft 38 is held againsty longitudinal nieve- ,ment, yet is free to rotate. Facing-plate 37' corresponds to plate 2.3 of bushing 16 and perfor'msthe same work of smoothing the end of thebottle`neckr y .v The interior-,die orformer consists of `two jawflike me1nbers'42, pivoted together and to rshaft '381,iu' the slot of the latter in scissors fashion, as indicated at 43. ARear ends 44 of the `jaws cross each other in diagonal lines, the extremities of the crossed parts forming four bearing-points 45, which protrude from shaft-slot -39 and hetweeirwhich cellar 46 is movable on shaft 38. orally grooved to receive angularfiugers 47, extending thereto from cone 13, the fingers passing through slots 48 in chuck 9. The operative endsof the die or former members are pointed and narrow in cross-section, and each carries a'nib or projection 50, which when the former members are separated turn groove 51 i in the neck interior forsealing or other purposes. Otherwise the divided-former performs the same work'inshaping the neck inyThe former is opened and closed by thesame movement of cone 13whieh aetuates dies 14. Different forms of grooves, depressions, tbc., may be Ahad by providing the former members with projections corresponding tothe effect desi red.

- rWhile iny'improvementsfare here shown and described in con nection-withformin g and .finishing a bottleneckLI de not limit myself thereto, as it may be readily adaptedy to other articles. Nor del restrict kmyginvention to inner and outer dies rotating in opposite directions, as they 'may be used 'independently of each other or in any other desired relation.

Also many details of construction may be vaaried without departing from the spirit or intent of the invention. j
