MACHINE FOR MANUFACTURING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 643,253, dated February 13, 1900.

Application filed October 5, 1397.

T at whom it may concern;

Be it known that I, FRANK ONEILL, of Cicero, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in Machines for the Manufacture of Glassware; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to machines for the manufacture of glassware; and the object of the invention is to provide an improved rapidly-working machine for the formation of tumblers, jelly-g1asses, and other articles of regular form. I

The present invention has particular refer- 2o ence to the cooperation between the pressing mechanism, the mold-carrier, and the moltenglass-separating means, whereby the pressing mechanism and molten-glass-separatin g mechanisms have unitary movement, alternating with the movement of the mold-carrier.

The invention consists in the novel features of construction hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which- 0 Figure 1 a perspective view of themachine, including only a portion of the mold-carrier. Fig. 2 is a side elevation of the pressing and actuating mechanisms, the former being in raised position. Fig. 3 shows the opposite side of the pressing mechanism in similar position. Fig. 4 is an elevation similar to Fig. 3, with the exception that the pressing mechanism is in lowered position, as indicated on the opposite side of the machine in Fig. 1, and also includes a portion of the moldcarrier. Fig. 5 is afront elevation of the pressin g and actuating n1echanisms,a portion of the former being shown in section. Fig. 6 is an enlarged sectional view of the upper portion of the pressingmechanism. Fig. 7 is an enlarged sectional view of one of the pressing-plungers. Figs. 8 and 9 are detail views of the spideractuating bolts. Fig. 10 is a detail sectional view of the ratchet connection between the Serial No. 654,149. (No model.)

Raised from base 1 are parallel overhanging uprights 2, slotted vertically at 3 and at their upper ends supporting vertical guides 4. 7o Movable on these guides is a head 5, connected at opposite ends by pitmen 6 and7 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 gearing 10 with powershaft 11.

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, respectively. 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-arranged plungers. The pressing mechanism is given a quarter-turn after each pressing or molding operation in order to bring the next succeeding plunger to operative position, and the mechanism whereby this turning is effected while the mechanism is raised 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 spider 20 is secured to the opposite end of the shaft between plates 14 and pitman 7. Secured to pitman 6 is cuff 21, carrying longitudinally-movable spring-held bolt 22, projecting normally into spider 19. This projecting bolt engages successively the under edges of the curved arms of spider 19, and as pitman 6 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 plunger-carrying head, is given oneeighth 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. While 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-quarterturn. This bolt is beveled on its rear vertical side, as indicated at 23, so as to readily slip over successively the extremities of the curved arms of the 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 it to the position indicated in Figs. 1 and 4. From the above description it will be seen that the turning mechanism at the left hand of the machine is active during the upward movement of the pitman, While that at the right-hand side is active during the downward movement of the same. Curved guards 20, standing out from the convex edges of the spider-arms, 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-ar|ns are notched at 19 to facilitate the beveled bolts slipping thereover in moving to 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. Cross-head 29, slidable on guides 4, is interposed between the cup and spring 30, the latter at its upper end engaging with the lower end of tube 25. By this means the cup is yieldable vertically and at the same time held normally depressed.

When 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 pressing mechanism.. When in this position, plates 14 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 14, and with them the pressing mechanism, are raised, the plates being in engagement with surfaces 17 of the eccentrics, which surfaces are concentric with the wrist-pin connections of the pitmen. This upward movement of the plates and of the 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 14, and these surfaces being concentric with disks 8 the upward 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 dawn to the then uppermostplunger. As surfaces 17 pass from under plates 14 the plunger mechanism and the pressing mechanismthat is, the pitmen and head 5-are rigidly connected and have unitary downward movement as the plunger enters the mold.

Mold-carrier 31 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 t-runnioned 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 successively beneath and in line with the pressing mechanism, and an intermittent motion beingimparted to the carrier by mechanism presently to be described each mold re mains in such position sufliciently long to execute the molding and pressing operation. Support 35, notched on its upper end at 36, 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 37, fiat on its upper side at 38, and as the molds approach the press disks 37 pass beneath upwardly-yieldable strips 39 and roll until flat portions 38 are brought in contact therewith, when the molds will pass to the glass feeding and cutting mechanism presently to be explained and to the press in upright position. After the molds carrying the molded articles pass from the press they are free to rotate, and when disk 37 meets downwardly-yieldable strip 4O, arranged beneath the plane of the carrier, the molds are inverted, so as to discharge the molded article. Ejecting-pin 41 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 gear 42,en gaging cog-wheel 32, said gear being loosely mounted on up right shaft 43. 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 up right shaft 47, said shaft being connected by bevel-gearing 48 to power-shaft 11. Vertically-moving 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 position the next mold. Each depression 50 is inclined 'at one end, and dog 49 slips freely therefrom when arm 44 is retracted, as when securing a new mold.

For locking gear 42 and the carrier in fixed position after being turned a proper distance vertically-movable two-part bolt 51 is provided, adapted to engage one of openings 52 in gear 42. The bolt is elevated by spider 54 on shaft 43, said spider engaging the lower hooked end of the bolt and movingit upward 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 occur ring 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 a new hold on gear 42, thus retractin g bolt 51 from gear 42 against the pressure of spring 53 and leaving the gear free for its next partial rotation.

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

While the machine here shown and described is provided with four plungers and with mechanism for securing a one-quarter turn of the plunger-carrying shaft for each operation, I do not desire to limit myself to this number, as a greater or less number of plungers may be provided, with the rotating mechanism varied as may be necessary to adapt it to the number used.

I will now proceed to describe the molten glass feeding and cut-off mechanism for supplying to each mold a predetermined quota of molten glass just prior to being brought to position beneath the pressing-plunger. The hopper is narrow and elongated, and its sides 60 are hollowed at 61 to provide space for the circulation of cold Water in order that the hopper may be retained at a uniform temperature. The opposite ends of the hopper are closed by feeding-wheels 62, mounted on shafts 63, said shafts having secured to their projecting ends gear-wheels 64. Secured to one of shafts 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 70 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, as shown, and extending through the peripheries'thereof are pins 72, which at their inner ends loosely embrace cam-flanges 73 on the inner surfaces of one of the hopper sides 60. Each of these cams is so disposed that the pins are held projected while turning downward 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 the usual manner, is drawn downward and forced through box 74, and said drawing mechanism as soon as its func tion is performed is retracted, so as to free itself from the molten glass and be entirely out of the way. Beneath the box 74 are oppositely-reciprocating knives 75, provided with suitable dovetailed slideways and carrying depending pins 76, 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.

WVhen 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 cut-off only when feed-wheels 62 and pins 72 draw downward the same. The motion of the 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 glass is discharged into the molds with accuracy as to amount and at regular and proper intervals.

The feeding and en t-off mechanisms greatly facilitate the manufacture of glass articles and .render the same uniform, as the supply of glass may be accurately gaged. If desired, however, the machine may be used without the feeding and cut-elf mechanisms, in which case the molten glass may be carried directly to molds from the furnace, as is now generally practiced.

The pressing-plungers are removably secured to the plunger-carrying head and the molds also removably secured to the carrier, so that said parts may be readily changed to conform to the particular work in hand.

Having thus fullydescribed my invention, what I claim, and desire to secure by Letters Patent, is-
