MACHINE FOR THE IVIANUFCTURE OF GLAAISSWARE.

SPECIFICATION forming para of Letters Pai-.ent No. 733,806, dated July 14, 190s. Application filed June 13, l899. Serial No. 720,422.v (No modeLl To @ZZ whom it may concern:

Beit known that we, CHARLES E. BLE. and WILLIAM B. JONES, citizens of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Machines for the Manufacture of Glassware, of which the following is a specification.

Our invention relates to improvements in machines for the manufacture of glassware, and pertains to a machine constructed to pro,- duce a finished article by a pressing and blowing operation, all of which will be fully described hereinafter.

In the accompanying drawings, Figure lis a front elevation of a machine embodying ourv invention. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 4. Fig. 3 is a similar view taken on the line 3 3 of Fig. 4. Fig. 4 is a plan sectionalview taken on the line 4 4 of Fig. 1.

Referring now to the drawings, A is a base or platform mounted upon wheels B for the purpose of enabling the machine to be readily moved around. Projecting from this base or platform A, preferably approximately at the center thereof, as indicated in Fig. 4, is a col"- umn or standard C.

D is a press-mold in which the molten glass is placed and in which a pressed blank is formed to be afterward expanded in a blowmold to its finished shape.

Situated at the left ofthe press-mold D is a blow or finishing mold F, and situated at the right of the press-mold D is another finishing or blow mold F..V These blow-molds are supported upon suitable standards 10, which project upward from the base or platform A at opposite sides of the press-mold. Situated between these standards is a cylinder G, carrying a piston. I, from which projects a piston-rod H, and this piston-rod H carries and supports the press-mold D and by means of which the press-mold is raised or lowered, as will be more fully described hereinafter.

Communicating with opposite ends of the cylinder G are the pressure-supply pipes J, and regulating the admission of the pressure to opposite ends of the cylinder is a verticallymovable valve K, which has openings arranged so that when the valve is in one position air is admitted to one end of the cylinder and when in the other position it is adl mitted to the opposite end of the cylinder for the purpose of raisingand lowering thepressmold. The valve K is normally held upward and air is normally admitted to the lower end of the cylinder G, a spring K' serving to hold the valve upward. Pivoted to the under side of the base is a treadle L, which isconnected with the lower end of the valve K, as illustrated in Fig. 2, and by means of which the valve is depressedhy the foot of the operator when it is desired to lower the press-moldA The blow-molds E and F preferably, though not necessarily, consist of two horizontallyopening sections and which are of the usual form.

Secured to the standard or lcolumn C is an by which it is supported. The ends of the oblong track M serveas stops for the carrier N, and thus always insures the neck-molds being supported directly over either the right or the left blow-mold and the intermediate press-mold.

The neck-rings P and P each consist of two separable portions of the usual form,and these are pivoted at their inner ends between the jaws O, and extending from one of the jaws between the two pivoted parts of the neckring is aV pin d, which pin is adapted to form a stop ,for the two parts of the neck-ring, so that they willalways be properly centered when closed over either the press-mold or one of the blow-molds.

The neck-ring support or carrier N is horizontally movable upon its supporting-track for the purpose of carrying the neck-rings into position to cooperate with they central press-mold and the blow-mold F in the posi- `tion shown in Fig. 1 and when moved to the opposite end of the track M to cooperate with the blow-mold E at the opposite side of the press-mold and with the press-mold. For the purpose of enabling this result the press and the blow molds are situated in a direct line and in a line track M.

Projecting from the column or standard C is a collar C', which supports cylinders for the purpose of operating the pressing-head and plunger and also for the purpose of operating the blow-heads, as will now be described.

A bracket F', projecting from the collar C', supports a cylinder G', in which is placed a piston W, carrying a piston-rod U, the piston-rod carrying at its lower end the usual or other form of presser-head Q and a plunger R, which is adapted to enter the press-mold when it is elevated for the purpose of forming a pressed blank within the press-mold, 111e parts assuming the positions shown in Fig. 2 when in act of pressing the molten glass. Communicating with opposite ends of this cylinder G' are pressure-supply pipes g, and regulating the supply of the pressure to opposite ends of the cylinder is a valve e, carrying at its lower end an operating-handle g'. This valve is normally held upward by means of a springf' and to thus normally admit air parallel to the supportingto the lower end of the cylinder and normally hold the plunger R in an elevated position.

We provide a blow-head m for each of the blow-molds, and these blow-heads are supported in a line directly abovethe blow-molds and adapted to coact therewith. The blowheads m are connected and carried by a tubular piston-stein M', which is connected at its upper end with an enlarged hollow stem p, the upper end of this hollow stem being formed into a piston o, situated within acylinder 9*, which is suitably supported by a i bracket r', extending from the standard or column C. The upper end of the hollow portion j) of the piston is provided with a valveseat, which is normally closed by a springpressed valve q, a spring p' being placed within the hollow portion p for the purpose of holding the valve normally to its seat.

Preferably, though not necessarily,we provide a pressure mechanism for opening and closing the blow-molds, and this consists of the two horizontal cylinders 12, each situated directly behind the molds E and F, and situated in these cylinders are the pistons 13, carrying piston-rods 14, the outer ends of the piston-rods having cross-heads j, which are connected to the two parts of each of the blow-molds by means of the links k. It will be readily understood that when the pistons are drawn backward or outward the molds are opened and when the pistons move inward the molds are closed. Communicating with opposite ends of these pistons are the pressure-supply pipes 2, which are preferably supplied by a main or common supply 1, and the admission of the pressure to opposi te ends of the cylinders is regulated by means of the valves 3, which are arranged to admit air to either end of the cylinders, according to their positions. The construction of these valves is well understood and lneed not be specifically explained. Springs S serve to hold these valves normallyrin a position to admit air to their outer ends and to thus normally hold the blow-molds closed. These valves 3 are operated by means of independent treadles 7, which are intermediately pivotally supported to the under side of the base A and have their inner ends connected by means of links 6 to bell-cranks 5, which in turn are connected by links Lt to the rear projecting ends of the valves, as clearly illustrated in Figs. 3 and 4. Thus it will be seen that by depressing either of the treadles 7 the operator-is enabled to open either of the blowmolds, and when the treadle is released the blow-m-olds will be automatically opened owing to the valve which regulates the pressure to opposite ends thereof being carried by its spring to the position of admitting air for closing the mold. Each of the cylinders 7' for operating the blow-heads are connected, respectively, by means of the pipes s and o with the cylinders 12, the said pipes s being connected with the lower end of the cylinders r and with the inner ends of the cylinders 12 and .the pipes o with the opposite ends of said cylinders.

In operation when one of the treadles 7 is depressed for the purpose of closing one of the blow-molds around the depending pressed blank air is admitted at the same time to the upper end of the coacting cylinder r for carrying downward the blow-head in position upon the neck-ring thereunder. This air is admitted directly to the cylinder 12 and must pass through the pipe fo to enter the cylinder fr. It will be readily understood that the cylinder 12 becomes first filled and its piston moved to the end thereof for closing the blowmold before the blow-head is carried downward to its position for expanding the pressed blank. than the pressure required to depress the piston o, and consequently the blowhead,where by the blow-head is first seated before the valve q is moved from its seat for admitting air through the stem and the blow-head to the blowmold for expanding the pressed blank therein, and when the pressure is released the valve q immediately reseats itself and the pressure of air is cut olii from the blowmold and the blowhead withdrawn from the neck-ring. From this description it will be noted that the air-supply for carrying the blow-head to position is used for eX- panding the pressed blank, which avoids the necessity of having separate supplies for the cylinder and for the blowing operation and which construction also enables us to automatically ad mit air for expanding the pressed blank, thus avoiding the necessity of separate hand operating devices or ot' separate automatic mechanisms for accomplishing this function of the machine.

In operation glass is placed in the pressmold either when it'is elevated or lowered, as may be desired, and if placed within the The spring p is ot' a strength greater IDO IIO

fsa,

blow-mold when in its lowered position it is then elevated to the position shown in Fig. 1. Then by a downward pull upon the valve eV the pressing-head and the plunger are carried into the position shown in Fig. 2 for forming the pressed blank. The operator then releases the treadle L, the press-mold is low-- ered, leaving the pressed blank suspended by the neck-ring P', Figs. 1 and 2, and the carrier N is then moved upon the track M to carry the neck-ring P' over the blow-mold E' at the right thereof. The operator then by depressing the treadle 7 closes the blow-mold E around the pressed blank, and the. blowhead is carried automatically, as before explained, to and upon the neck-ring, as illustrated in Fig. 3, and air is admitted to the blow-mold and the pressed blank is expanded. The treadle 7 then being released, the blowmold is automatically opened, the blow-head automatically moved upward, and thenthe turning-out boy has simply to open the neckring and remove the finished article. This operation is continued,the neck-ring P being in the position in which the neck-ring P is shown in Fig. l when the pressed blank is being expanded in the blow-mold F., and molten glass having been placed in the pressmold it is pressed, and the carrier N is then moved to the position shown in Fig. l, which carries the pressed blank to the blow-mold F, and there the operation just described is repeated. From this description it will be seen that a pressing and a blowing operation are being carried on at the same time and that at each operation of the machine a finished article is produced.

While we have explained a pneumatic mechanism for opening and closing the blowmolds and have shown a closed verticallymovable press-mold, we do not limit ourselves to these specific constructions so far as the other mechanism of the machine is concerned, in that the press and the blow molds can be of the ordinary open-and-shut construction and operated by hand, as will be readily understood so far as the specific form of carriers for the neck-rings is concerned. We also wish it understoodV that instead of using two blow-molds a single blow-mold may be used without departing from the spirit of our invention.
