To ctZZ whom/ it may concern:

Be it known that LFRANK ONEILL, a citizen of theUnited States, residing at Cicero, in the countyof Hamilton and State of Indiana, have'invented new and useful Improvements in Machines for the Manufacture of Glassware, of which the following is a specification. V This invention is a division of my application filed October 5,1897, Serial No. 654,149.

The present invention has particular referenee to improved pressing mechanism, improved molds and mold -carrier, improved molten-glass-feeding mechanism, and to the cooperation of the pressing and feeding mechanisms and the mold-carrier.

Fig. 16 is a plan view, partly in section, of the molten-glass-feeding and cut-off mechanisms. Fig. 17 is a vertical cross-sectional view of the same. Fig. 18 is a longitudinal section. Fig. 19 is a detail plan view of the actuating-disks and cut-off knives. Fig. 20 is a detail view of the open box for passing glass to the'knives. Fig. 21 is a detail view of the wrist-pin connection for regulating the speed of the cutoff mechanism.

Raised from base 1 are parallel overhanging uprights 2, slotted vertically at 3 and at their upper ends supporting vertical guides 4, Movable on these guides is head 5, connected at opposite ends by pitmen 6 and 7 to disks 8, the latter being secured to opposite ends of short shaft 9, journaled transversely on the lower portion of uprights 2, said shaft being connected by shaft 11. V I I The vertically reciprocating revoluble pressing mechanism is mounted on shaft 12 between uprights 2, said shaft being journaled in boxes 13, movable in slots 3. Shaft 12 is sustained and reciprocated by the angular plates 14:, slotted at 15 and 15 to move vertically on guide-bolts 16 and 16, respecgearin g 10 with powertively. The lower reduced ends of said plates bear upon and are reciprocated by eccentrics 17, secured to the inner sides of disks 8.

The pressing mechanism here shown includes four plungers 18, arranged radially on shaft 12 and at equal distances apart, thus bringing in line two oppositely-'arran ged plungers. The pressing mechanism is given a quarter-turn after each pressing or molding operation in order tobrin g the next succeeding plunger to operative position, and the mechanism for effecting the turning of the raised plungers will now be described.

Facing the machine'as seen in Fig. 5 spider 19 is secured to the left-hand extremity of shaft 12 between plates 14 and pitman 6, and spiderp20 is secured to the opposite end of the shaft between plates 14 and pitman 7. Secured to pitman 6 is cuff 21, carrying longi tudinally-movable spring-held bolt 22, projecting normally into spider'lt This projecting bolt engages successively the under edges of the curved arms of spider 19, and as pitman G swings in a greater are than said arms the bolt moves inward under the latter while being raised from the position indicated in Fig. 1 to that shown in Fig. 2, with the result that the spider, and with it the plungercarrying head, is given a one-eighth turn. The under horizontal side 22 of bolt 22 is beveled, so as to be automatically pressed back by the next succeeding arm and engage its under edge when the pitman is lowering to position shown in Fig.1, as when pressing or molding an article. Vhile bolt 22 is active in turning spider 19, bolt 23, similarly mounted in cuff 24:, secured to pitman 7, is being brought to operative position with relation to spider 20 in order to complete the one-rpiarter turn. This bolt is beveled on its rear vertical side at 23 to readily slip over successively the extremities of the curved arms of spider 20, so as to engage their convex edges, as seen in Fig. 3. Thus with the pitman advancing toward the center of the spider and at the same time moving downward the spider is turned sufficiently to complete the one-quarter turn and bring to position indicated in Figs. 1 and 1-. Thus it will be seen that the turning mechanism at the left hand of the machine is active during the upward movement of the pitmen, while at the right-hand side it is active during the downward movement of the same. Curved guards 20, standing out from the edges of the spiderarms, hold bolt 23 positively thereto and prevent the pressing mechanism from rotating too far. As an additional precaution spider 19 might be provided with similar guards; but I deem it sufficient to positively guide said mechanism during the latter part only of its movement, as this insures accurate positioning of the plungers. The spider-arms are notched at 19 to facilitate the beveled bolts slipping thereover in moving in engagement therewith.

Adjustable vertically in head 5 is tube 25, the same being held in proper position by nuts 26, and extended therethrough is bolt 27, adjustably secured at its upper end by nuts 27 and at its lower end carrying cup 28.

Gross-head 29, slidable on guides t, is interposed between the cup and spring 80, the latter at its upper end engaging the lower end of tube 25. l3y this means the cup is yieldable vertically and at the same time held norin ally depressed.

\Vhen the downwardly-disposed plunger 18 is in operative position, as seen in Fig. 4, the upright plunger is engaged by cup 28, whereby downward pressure is imparted to the pl ungers. \Yhen in this position, plates 11 are in their lowermost adjustment, the extremities thereof riding on the short sides of cams 17, as clearly shown in said figure. As soon, however, as pitmen 6 and 7 begin to rise plates 1-1, and with them the pressing mechanism, are raised, the plates being in engagement with surfaces 17 of the eccentrics, said surfaces being concentric with the wrist-pin connections of the pitmen. This upward movement of the plates and pressing mechanism is only sufficient to draw the plunger from the mold, and when this has been accomplished surfaces 17 of the eccentrics are brought in contact with plates 1t, and these surfaces being concentric with disks 8 the u pward movement of the plates ceases; but the upward movement of the pitmen and head 5 continues in order to release cup 28 from its plunger and leave the plunger-carrying shaft free to turn. It may be stated that the uppermost plunger is released before the pitmen and head 5 reach the limit of their upward movement, as ample time is afforded the shaft to turn the next succeeding plunger to operative position before cup 28 is brought down to the then uppermost plunger. As surfaces 17 pass from under plates it the plunger mechanism and the pressing mechanism that is, the pitmen and head 5are rigidly connected and have unitary downward movement as the plunger enters the mold.

The mold-carrier is centrally mounted on an extension of base 1, and consists of a series of spokes carrying at their outer ends the large circular gear-wheel 32 and within said wheel circular strip 33. Molds 34 are trunnioned on opposite sides, where they are journaled to wheel 32 and band 33, and between which they are adapted to freely swing. The molds are passed successivelybeneath and in line with the pressing mechanism and an intermittent motion being imparted to the carrier by mechanism presently to be described each mold remains in such position sufficiently long to execute the molding and pressing opcrations. Support 35, notched on its upper end at so, is arranged to support the carrier directly beneath the mold when receiving the plungers, so that the carrier is relieved of all strain. Secured to and rotatable with the inner trunnion of each mold is a disk #7, flat on its upper side at 38, and as the molds approach the press disks 37 pass beneath upwardly-yieldable strips 39 and roll until flats 38 are brought to engagement therewith,when the molds will pass in upright position to the glass feeding and cutting mechanism, presently to be explained, and to the press. After the molds carrying the molded articles pass from the press they are free to rotate, and when disk 37 meets downwardly-yieldable strip 40, arranged beneath the plane of the carrier, the mold is inverted, so as to discharge the molded article. Ejecting-pin 4:1 in the bottom of each mold drops against the article and forces out the same, and should it show any inclination to stick the pin may be tapped lightly with a hammer or other implement.

The carrier is afforded an intermittent rotary movement by geari? engaging cog-wheel 32, said gear being loosely mounted upon shaft 13. Secured to the upper end of said shaft over gear 42 is arm 44, connected at its outer end by link 45 to crank 46 on upright shaft 47, said shaft being-connected by bevelgearing 48 to power-shaft 11. Verticallymoving spring-actuated dog 49, carried by arm 44, is adapted to engage one of depressions 50 in gear 42 and impart to the gear a quarter-turn, a movement sufficient to remove one mold from beneath the plunger and to move the next succeeding mold from beneath the cut-0E, presently to be described,

7 to position for pressing. Each depression 50 is inclined at one end, and dog 49 slips freely therefrom when arm 44 is retracted, as when securing a new hold.

For locking gear 42 and the carrier in fixed position, with adjacent molds in position beneath the press and cut-off, respectively, the vertically-movable two-part bolt 51 is provided, adapted to engage one of openings 52 in gear 42. Y The boltyis" elevated by spider 54 on shaft 43, said spider engaging the lower hooked end of the bolt and moving it upward against the pressure of spring 53 until alined with one of openings 52, into which the upper section of the bolt is forced, this occurring at the completion of the movement of gear 42. The spider is turned backward by shaft 43 and arm 44 when the latter is moving to position for anew hold on gear 42, thus retracting bolt 51 from gear 42 against the pressure of spring 53 until alined with one of the openings 52, into which the upper section of the bolt is forced, this occurring at the completion of movement of gear 42. The spider is turned backward by shaft 43 and arm 44 when the latter is moving to position for a new hold on gear 42, thus retracting bolt 51 from gear 42 againstthe pressure of the spring, leaving the gear free for its next partial rotation.

Each plunger carries a mold-cover 55, yieldably held byrods 56 and springs 57. The inner ends of said rods are secured to head 58, adjustable on plunger-stem 59, and by this means the position of the mold-cover maybe varied as required. x

While the machine here shown and de- 4 scribed is provided with four plungers and hollowed at'61 to provide space for the circulation of cold water in order that the hopper maybe kept at a uniform temperature. The

opposite ends of the hopper are closed by feeding-wheels62, mounted on shafts 63, said shafts having secured to their projecting ends gear wheels 64. 63 is ratchet-arm 65, connected by pitman 66 to wheel 67 at the end of shaft 68, said shaft at its opposite end carrying gear 69, meshing with gear 7 O of power-shaft 11. Pitman 66 has an adjustable wrist-pin connection with slotted wheel 67, as indicated at 71 Fig. 21, so that a greater or less movement may be imparted to the feeding-wheels, as may be necessary. Wheels 62 are open at one side, and extending through the peripheries thereof are pins 72, which at their inner ends loosely embrace cam-flanges 73 on the inner surface of one of the hopper sides 60. Each of these cams is so disposed that the pins are held projected while turningdownward toward the centrally-arranged box 74, but are retracted thereby,so as to be flush with the wheel-periphery when passing said box, so as not to catch thereon. By this means the molten glass, which is supplied to the hopper in usual form, is drawn downward and forced through box 74,and said drawingmechanism as soon as its function is performed is retracted so as to free itself from themolten glass and be entirely out of the way. I Beneath box 74 are oppositely-reciprocating knives 75, provided with suitable dovetailed slideways and carrying depending pins 7 6, which are embraced by eccentric grooves 77 of wheels 78. Short shafts 79 are geared to these wheels and to shaft 68 for imparting proper motion to wheels 78 for actuating the knives.

When the machine is in operation, the hopper is kept filled with molten glass, and the consistency of the same is such that it will pass downward through box 74 and to the cutofi only when feed-wheels 62 and pins 72 draw downward the same. Wheels and pins is so regulated and capable of such adjustment that only a given or predetermined quota will be fed at each intermittent movement thereof, 'so that the molten Secured to one of shafts The motion of the IIO glass is dischargedinto the molds with ac- From the foregoing description it will be understood that the operations of the plunger and cut-off are simultaneous and that said parts are at rest during the positioning of the molds by movement of the carrier. In other words, there is an intermitting alternating movement of the mechanisms mentioned, whereby the work is accomplished in a quick and effectual manner. At the same time they all receive their motion from a common source, so that the whole operation is mechanically accurate. v

Claims specific to thecooperation of the pressing mechanism, the molten-glass cut-off per se, and the mold-carrier are not included herein, as such subject-matter is claimed in the original application.
