To (6 whom it may concern.-
Be it known that I, DANIEL MURRAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Glass-Blowing form and arch-beam broken away and onehalf of one of the divided matrices removed, disclosing a bottle and the members of the machine adapted to form said bottle shown in position after the finishing thereof; Fig.

gaging thereby with the locking-bolt adapted to prevent longitudinal movement of the shaft duringa revolution of the revolnble platform; Fig. 12, a cross-section of the tubular shaft on line'a b of Fig. 10, indicated with the plunger-rod and tension-spring therein and the socket-head thereon; Fig. 13, a cross-section of the revolnble platform on line A B of Fig. 14., indicating the gear-sector and pinions adapted to operate the rotatable disks and the platform shown when about to complete an entire revolution; Fig. 14:, a side elevation of portions of the revolnble platform and frame end with means thereon for operating the rotatable disks; Fig. 15, a sectional View of the upper portion of a matrix, indicating the plunger about to be released by the pawl; Fig. 16, a transverse section, on large scale, on line w y of Fig. 1, but indicating the revolnble platform and attached parts in relative position at the end of a part of a revolution in the direction indicated by the arrow attached by the radial line to the trunnion thereof. This figure indicates also modified means for inserting the blowpipe into the mold when producing articles having a large mouth, and Fig. 17 is a similar section of the revolnble platform when in its normal position and with a cam employed to actuate the blowpipe pendent therefrom.
In the construction of my machine I have provided any suitable frame, as O, which may comprise end pieces 0 and C and a carrying-beam C attached thereto. Journaled in the end pieces 0 and O of frame 0 are trunnions D and D, adapted to provide pivotal support for a platform, as P, which is preferably offset thereon, so as to normally hang thereby, and, as now considered, supports an arched member, as P. The offset platform P and arch P are adapted to revolve with the trunnions D and D as rotated by any suitable means, which may comprise a friction-pinion d, journaled in the frame 0 and provided with any desirable means for rotation, such as pulleys d. This frictionpinion d is adapted to contact a frictionwheel d secured to the trunnion D, and to rotate same when the peripheries are brought in contact and to also provide intermittent rotation, and for discontinuance of motion of the platform P at the end of each revolution I have introduced a cave d in the periphery of the wheel 6?, thus breaking contact of the frictions, as clearly indicated in Fig. 2. It will be clearly understood that the wheel 61 may be constructed with one or more caves d as might be desirable, for the intermittent operation of the machine.
The platform P is offset on the trunnions D and D to provide for the operation of mechanism introduced to rotate the disks p, as will hereinafter be fully set forth, and to counterbalance the pendent parts attached to the platform P, and thus render it easier of movement.
To check the momentum of the revolving members attached to the trunnion D, a friction brake-band e is introduced about the wheel (1 and is adapted to contact same by a movement of the foot-lever e.
In the platform P are journaled disks 1), adapted for rotation, if desirable. These disks are each provided with a central aperture 10 for the introduction of a reciprocal blowpipef to a mold F, mounted thereover or thereon for support, and are adapted to perform certain functions in finishing the article blown, as will hereinafter be more fully set forth and described.
The molds F are diametrically divided and hinged as in ordinary practice and are removably secured to either the platform P or disksp, or to both, as in composite molds, (indicated in Figs. 4 and 5,) and are adapted to be rotated by the disks 1) or the rotatable tubular shaft G, which is mounted in the arch-beam P The tubular shafts G are adapted to rotate the molds F or the plunger F in the molds and are provided with gears g, meshing with similar gears g, mounted upon the arch-beam P and adapted to rotation during a certain portion of each revolution of the platform P by means of pinions g engaging rack-segments 9 provided in their path of travel as they revolve with the platform.
On the upper ends of the shafts G are provided heads h, adapted to engage yokes h, provided at the lower end of the lifting-rods H, which are adapted to raise the tubular shafts G and withdraw the plungers F for the purpose of admitting the molten glass into the molds B when in an upright position, whereupon the shafts G are lowered, and the plungers F, entering the molds, compress the molten glass into the lower section thereof by the gravity of the plunger.
The plungers F are each provided with a square shankf,adapted for rectilinear movement in the tubular shaft G and are held to rotation therewith by means of a socket-head G, secured to the shaft G and provided with a square aperture f to receive the shank f and with earsf to engage the molds F to rotation therewith when desirable.
To lock the tubular shafts G from end movement during a revolution of the platmat form P, a reciprocatinglatch-rod '1} is provided in the arch-beam P having latch-bolts t" thereon adapted by action of the spring i to engage an annular groove g provided on each shaft G,but shot from engagement therewith at the end of each revolution of the platform P by the head 2' contacting the face 72 of the radial incline 1, thereby permitting the shaft to be raised,as heretofore explained. To accomplish the production of different sizes of articles with the same mold, I have provided for an adjustment of the plunger F by introducing a movable plug f which is adjusted in the tubular shaft G by means of a screw f bearing in the head It.
The tubular shaft Gmay be provided with a tension-spring f bearing against the plunger-shank f to resist the gravity of the plunger, and a gravity-pawl f may be pivoted in the head G to engage suitable teeth in the shank f for the purpose of raising the plunger with the tubular shaft. This pawl f is provided with an arm 1, adapted to contact with the upper end of the mold when the shaft is lowered and release the shank f and permit the plunger F to drop upon the molten glass in the mold,and upon introducing compressed fluid to the molten glass in the mold the plunger is raised until the shank thereon contacts with the plugf provided in the tubular shaft.
To introduce compressed fluid to the several molds of my machine, the trunnion D is preferably rendered hollow and provided at the outer end with a cap 61 which is held from rotation and provided with an aperture 2, adapted for the passage of fluid from a supply-pipe d to the chamber (1 of the trunnion through a semicircular slot (1 during a predetermined portion of the rotation of the trunnion. At the opposite end of the chamber d may be provided a conduit 7t, leading to the blowpipe of the first mold and having branch conduits 7a and k communicating with the blowpipes of the other molds. Each conduit may be provided with a valve k adapted to cut off the supply of fluid from either mold independent of the supplyto the other molds.
To introduce com pressed fluid into the molten glass compressed by the plunger F into the bottom of the mold and to form the inside of the neck of the article to be blown, I have provided a reciprocating blowpi-pe f, carrying a tip m of any desirable form, as indicated in Figs. 6, 7, and 16, and adapted to form the mouth of the article to be blown and having a gravity-valve n to protect the mouth of the tip from being filled with molten metal. The blowpipefis guided by a tube-casing a, secured to brackets 5, and is forced to enter the mold at a predetermined point during the revolution of the platform P by a cam N or gear-sector N, mounted upon a shaft 6, journaled in the brackets 5, which are pendent.
from the platform P. Upon this cam N rests the blowpipe f, which may be provided with a square shank 7 to keep the intake-aperture 8 in line with the mouth of the supply-conduit,
which is attached in the casing n,or this shank 7 may be provided with a toothed rack g,adapted to engage the gear-sector N, and a plumbweight T is secured to the shaft 6 to rotate the cam N as the platform P revolves. It will be understood that the plumb-weight T remains in a vertical position during its revolution about the horizontal center line of rotation with the revolving platform. Thus the face of the cam acts upon the end of the shank 7 of the blowpipef, or the gear-sector N engages the toothed rack 9 and forces the blowpipe into the molten glass, as heretofore explained, and upon a completion of the revolution the gravity of the blowpipef and pressure of compressed fluid contained in the article blown forces it to drop to its original position as the heel 11 of the cam N clears the end of the shank 7, or the return of the blowpipe may be insured by a spring 10, as indicated in Fig. 17. As the blowpipefis forced into the molten glass the intake-aperture 8 registers with the mouth of the fluid-conduit, and the compressed fluid raises the gravityvalve 12 and inflates the glass, forming the article in the mold and assisting in raising the plunger F until the shankf thereof contacts the adjustable plug f which limits the length of the article blown.
To provide automatic rotation of the several disks p, a reciprocating rod B may be introduced, having a head 1 adapted to contact the face 1' of the radial incline R during a predetermined portion of revolution of the platform P and provided with return action at the end of the incline by means of a spring r This rod R is pivoted to the disks 1) by crank pins 1" and upon reciprocation, as above described, an alternating rotary movement is imparted to the disks. A rotary movement of the disks 1) may also be provided by introducing a bevel-pinion V, engaging suitable teeth provided upon the disk, as indicated in Figs. 13 and Lt, and mounted on a shaft 20, bearing in brackets 21, pendent from the platform P and mounting a spurpinion 22, adapted to mesh with a gear-sector V during a predetermined portion of the revolution of the platform. It will be clearly understood upon reference to Fig. 14 that motion may be transmitted from one disk to the other by means of pinions B and shafts 25.
Having thus fully described the mechanism comprising my invention, a complete operation thereof would occur as follows: The operator takes a position on the right in Fig. 2, whereupon the tubular shafts Gand plungers F are raised by the lifting mechanism heretofore described. The molds F being closed and locked the molten glass is introduced therein from the top, whereupon the tubular shafts are lowered to their normal position, as indicated in Figs. 1 and 2, and the plungers F are released by the pawls f if employed, dropping by gravity upon the molten glass and chilling the surface thereof con tacted by face of plungers and giving form to the bottom of articles to be blown, also forcing the metal into the lower portion of the molds and about the tips of the blowpipes in the disks, as indicated in Fig. 5. The platform P is then revolved sufficiently to contact the peripheries of the friction-wheels d and d and motion is imparted to the platform by the driving-wheel (Z. As the archbeam P moves to the left in Fig. 2 the locking mechanisms of the tubular shafts G are released from the incline I, and the bolts 7 are shot into place by the spring action heretofore described. As the platform Prevolves the plumb-weights T actuate the cams N, forcing the blowpipe-tips into the molds, forming the mouth and throat of the articles, and registering the intake-apertures S with the mouth of supplvconduits, whereupon compressed fluid is admitted to the blowpipes by the opening of the valve on the end of the chambered trunnion D. The pressure of the admitted fluid opens the valves 17. in the tip of the blowpipes f, and the articles are blown during a predetermined portion of the revolution of the platform and pendent mechanisms. As this occurs the internal pressure of the fluid inflating the metal in the molds forces the plungers F outward to the limit determined by the position of the adjustable plugs f contained in the tubular shafts G, adapted thereby to determine the length of the articles being blown. Continuing the revolution the supply of compressed fluid is cut off at a predetermined point by action of the valve (i on the end of chambered trunnion D, and the surfaces of the blown articles are finished by a rotation of the articles in the molds or the molds or sections of the molds about the articles during the remainder of the revolution. This may be accomplished in different ways, according to the nature of the articles blown.
The action of the mechanism employed in finishing the article may be varied according to the style of the article blown, as indicated in Figs. 1, 3, 4-, 5, and 16, and is intended to substitute the ordinary method now employed in finishing the article. In finishing the article indicated in the mold on the left in Fig. 1 it is intended that the disk 19 remainstationary in .the platform P, and the article is rotated by means of the plunger F, which forms the bottom and holds thearticle to rotation thereby, while the pinion g engages the rack g during the revolution of the platform P.
In Fig. 3 it is intended to lock from rotation the plunger F and its carrying mechanism contained in the arch-beam P and to afford a rotation of the disk 1) and mold contained thereon about the article blown, which is held from movement by contact with the plunger F, the movement of the disk being accomplished by either of the means heretofore mentioned.
In Fig. 4 it is intended to finish the article by a rotation of a section. of a mold, asf

which is driven by the disk 19, while the remainder of the mold and the article-blown are held stationary.
In Fig. 5 it is intended to finish part of the article by a rotation of the plunger F, upper section f of the mold, and the article blown therein by means as described for Fig. 1, the lower partf of the mold and disk 19 being held from rotation in the platform P by any ordinary means, as dowel-pin 12. In certain instances the blowpipe tip may be held in position in the mouth of the article during the rotation thereof to give full finish to the inside mouth. As the platform P is nearing a completion of a revolution the friction-band 6 may be employed to check the momentum and stop the platform, with the heads h engaging the yokes h, whereupon the plungers F may be raised, the molds opened, and the blown articles removed.
A plurality of molds is introduced to admit resting one or more molds for the purpose of cooling during an operation of the remaining molds.
