GLASS-SHAPIN G MACHINE.

Specification of Letters Patent.

Patented Nov. 6, 1917.

To all whom it may concern:

Be it known that I, MICHAEL J. Owens, a citizen of the United States of America, residing in the city of Toledo and county of Lucas, State of Ohio, have invented certain new and useful Improvements in Glass- Shaping Machines, of which the following is a specification, reference being had therein to the accompanying drawings. i

The invention consists in a machine for shaping glass, comprising mechanism for making a blank and a transfer-device for taking the glass blank and transferring it, as, for instance, inthe machine here illustrated, to a blowing-mold in which it may be blown to finished form; and further, in the construction, arrangement and combination of the blank-forming, transfer and blowing devices, as more fully hereinafter described and pointed out in the claims.

I have here illustrated a traveling blankforming mechanism of the type in which the blank is gathered into the blank-mold from the tank of molten metal, this mechanism being ofthe kind shown in the Bock Patent No. 870,664, dated November 12th, 1907, and :atrave'lin-g blowing-mold arranged beside the blank-forming mechanism with a transfer-device to move the blank from one to the other.

In the drawings:

Figure 1 is a diagram plan of the blankforming and blowing mechanism, showing the transfer mechanism in plan on the rotary table of the blowing mechanism;

Fig. 2 is a side elevation of a portion of the blank-forming mechanism, showing one mold in the gathering position and another mold having its lower or body portion open, leaving the blank suspended by the neck ready for the transfer mechanism to engage it;

Fig. 3 is a side elevation of a portion of the blowing-mold, in position to receive the blank; and

Figs. 4, 5 and 6 are side elevations of the blowing-table beside the mold, partly in section, showing the transfer mechanism in different positions during the transfer operation.

I do not deem it necessary to explain in detail the construction of the gathering blank-forming machine. as that is of the type of what is known as the Owens machine, and of the kind shown in the Bock patent above referred to. I

' In short, this machine comprises a base 1 on wheels 2, supporting a central post or pillar (not shown) on which rotates the frame 3. This frame carries a series of mold-arms 4 on each of which is supported a blank-mold. This blank-mold is made in two portions, the upper portion 5 called the neck-mold, made in separable halves carried on hinged arms 6 and automatically opened and closed as the frame rotates, and the lower or body portion 7, made in separable halves carried on the hinged arms 8, which are likewise automatically operated by suitable cams (not shown) for opening and closing the same during the travel of the frame.

The tank of molten glass is shown at 9, and during the rotation of the frame each mold is caused to lower at the tank to cause its lower, open end to touch the glass, at which moment the air is exhausted from the mold, which causes the mold to be filled with glass and the blank formed. At the upper end of the mold a pin 10 projects into the neck-mold to form an initial blow-opening and more perfectly form the neck of the blank, especially if a bottle is to be blown.

In the rotation of the frame and the blank-forming mechanism the lower edge of the mold is dlpped to the glass and the glass forced into the mold to form the blank, a cut-off (not shown) severs the string of glass from the bottom of the blank-mold,

. and the blank-mold is moved away from the molten glass tank. As the mold travels away from the tank the sections of the body blank-mold are opened by a suitable cam mechanism to the position shown at the lefthand of Fig. 2, leaving the blank 12 suspended from the neck-mold. Mechanism is provided in the further travel of the blank-mold for opening the neck-mold sections to release the blank. Mechanism is also provided for closing the sections of the body blank-mold and the neck-mold, and for raising and lowering the plunger 10; these operations being carried on by suitable cams and operating connections which are well-known and which are illustrated in the Book patent herein referred to.

Adjacent to this blank-forming mechanism is a blowing machine or blowing mechcarriage.

anism. This machine may be on the same frame or carriage (1) with the blank-forming mechanism or it may be on a separate I have shown it on a separate carriage 15, having suitable wheels so that the two machines may be moved side-by-side as shown in diagram in Fig. 1.

This blowing mechanism as here shown comprises a standard 16 upon which there is a rotating frame 17, on which are a series of blow-molds 18 made in sections, which sections are adapted to be opened and closed through the connections 19 which are operated by a roller 20 engaging with a cam 21 on a stationary pillar 21*. On the same illar at the top are arms '22 which guide the low-heads 23, actuated by a lever 24, which lever has a crank-arm 25 having a roller 26 engaging a cam-way 27 secured to the pillar 21*. the blow-head is raised and lowered to and from the blow-mold in the well-known way. The blow-head is connected with a source of air under pressure through the pipe 28.

The blank-forming and blowing mechanisms being arranged side-by-side and traveling as shown by the arrows in Fig. 1, in order to transfer the blank from the blankforming mechanism I employ the following apparatus: Secured on the travelingframe, or table 17 is a slide 30 working in radial guides 31 and having a roller 32 at its inner end engaging a cam-way 33, which cam-way is secured to the pillar 21 and is shaped to move the slide 30 in and out. The slide is provided on one face with the rack 34 which meshes with the gear-wheel 35, which gearwheel is journaled at its lower end in the bracket 36 working in vertical guides 37 depending from the under-side of the table. The bracket is provided with an inwardlyextending arm 38 having a roller 39 engaging a cam-way 40 secured to the central pillar or pedestal below the rotating table or frame, this cam being of such shape as to raise and lower the bracket 36 and with it the gear-wheel 35, at the proper time to carry out the functions hereinafter described.

The gear-wheel 35 passes through and is guided by a sleeve 41 which is secured to the edge of the rotating table 17 near the blow-mold. At the upper end of the gearwheel-35 is attached a transfer-arm 42, in the manner of attaching a crank-shaft. This transfer-arm at its outer end is pro vided with a forked blank support 44.

In arranging the blank-forming and blowing machines adjacent each other the blankforming machine is arranged so that its molds travel on a higher level than those of the blow-mold, the diflerence in elevation of the two being shown in Fig. 4, where the blank is shown as being transferred from the blank-mold and arranged at about the level The cam is of such construction that of the blank-mold, to a position above the blow-mold. The parts being thus constructed they operate as follows:

The blank-forming mechanism will gather the glass and form a blank, in the wellknown manner, during the rotation of the frame of that mechanism, and then during the travel of the frame from the tank where the glass. is gathered the lower portion, or body blank-mold, will open, as shown at the left-hand of Figs. 1 and 2, leaving the blank suspended from the neck-mold, At this point in the operation the blank mold most nearly approximates the blowingmechanism, and the gear-wheel 35, through the cam 40, will hold the transfer-arm 42 on a level with a; point just below the bottom face of the neck-mold. The slide 30, by its cam 33, is drawn inward at this point, rotating the gear 35 and swinging the transferarm around, so that the supporting fork will embrace the blank just below the neckmold (as shown in Fig. 1). As soon as this happens the neck-mold will be opened and will drop the blank from the neck-mold to rest upon the fork, the blank being provided with an enlarged head 50 which supports it in the neck-mold and which will support it as it drops a short distance onto the forked support of the transfer-arm. 'As soon as this happens the slide 30 is pushed outward, by the cam, which rocks the transfer-arm from the position shown in Fig. 1 to' the position shown over the blow-mold. When the blank reaches the position over the blow-mold the cam 40 will lower the gear 35 and its supported transfer-arm 42and with it the blank-into the blow-mold, as shown in Fig. 5. Then the further outward movement of the slide 30 will disengage the transfer-arm from the blank and allow it to drop into the blow-mold with its upper end, or head, resting upon the upper edge of the mold, and will also withdraw the transfer-arm to a position laterally beyond the blow-mold, as

shown in Fig. 1.

WVhen the blankhas thus been transferred to the blow-mold, the cam 27, operating the lever 24, will lower the blow-head upon the blow-mold and, air being admitted (which is usually done by the lowering operation of the blow-head), will blow the blank to completed form in the blow-mold.

At a suitable point in the rotation of the table or frame 17 the blow-head will be raised (and the air shut off) and the mold opened, so that the blown article may be removed therefrom; the blow-mold closing before it again returns to position to receive a blank from the blank-forming mechanism.

The mechanism described is especially desirable for the manufacture of very large ware-such, for instance, as three or five gallon glass bottles or receptacles or other similar glass-ware.

So far as I am aware I am the first to de use an apparatus in which a blank is formed combined with a blowing mechanism and a transfer mechanism which engages and removes the blank from the blank-forming mechanism to the blowing-mechanism. While I have shown and described an apparatus in which the blank is brought above and lowered into the blow-mold, it is obvious that the blank may be moved into the blowmold while open and the blow-mold thereafter closed, but this is a mere matter of timing the cams for opening and closing the blow-mold in relation to the feeding movement of the blank theretolVhat I claim as new is:
