SPECIFICATION forming part of Beissued Letters Patent No. 1 1,890, dated February 19', 1901. Original No. 650,722, datedllay 29, 1900. Application for reissue iiled September 25, 1900. Serial No. 31,117.

To all whoml it mty concern:

Be it known that we, CHARLES E. BLUE and WILLIAM B. JONES, citizens of the United States, residing at W'heeling, in the county" of Ohio and State of West Virginia, havei'nvented new and useful Improvements in Machines for' the Manufacture of Narrow-Neck Bottles, of which the following is a specification.

Our invention relates to improvements in machines for the man ufacture of narrow-neck bottles, and pertains to a machine constructed and adapted to produce a pressed blank, which is afterward blown into its finished form.

In the accompanying drawings, Figure 1 is a vertical sectional view taken on the line 1 1 of Fig.- 3. Fig. 2 is a vertical sectional view taken on the line 2 2 of .Fig. 8. Fig. 3 is a top sectional view taken on the line 3 3 of Fig. 2.' Fig. 4 is a top plan view of the machine embodying our inyention, one set of the molds being omitted. Fig. 5 is an enlarged detached plan view of the plunger-support and the gear-wheel with sufiloientnumber of teeth to have the plunger-support eooperate with five sets of molds instead of with four, as illustrated in Fig. -i.- Fig. 6 is a similar view to Fig. 5, showing the gearwheel with a proper number of teeth to revolve the plunger-support in unison and to cooperate with four sets of molds, as shown in Fig. 4. Fig. 7 is a detached view of the inolds and their suppo ting table or plate, one-half of the press-mold being removed and the parts of the blow-molds shown open.

Referring nowto the drawings, A indicates a base supported, preferably, upon the wheels B, by means of which the base, and consequently the machine carried thereby, can be moved around as desired. Projecting from this base is a column or standard 24, carry-- ing at its upper end a bracket or arm 0, which supports at its outer end a cylinder 18. Surrounding this column or standard 24 at a point intermediate its ends is a table or bearing 23, to which is supported a plurality of base-plates 1% in any desiredmanner. This table 23 is supported by a ring D, carried by the column 24, there preferably being a ballbearing E between the table or collar 23 and the supporting-ring D.

tically, as will be readily understood from Each of these tables 13 also the drawings. supports a two-partblow-niold 4, which is horizontally pivoted at the point I and adapted to open outward, as illustrated in Fig. 3.

'VVhen the blow-mold is open, it is-entirely out of the way of the two-part press-mold, and when the press-mold is open it is entirely out of the way of the blow-mold, as is also clearly illustrated. These tables 13 are vertically rotatable and each is provided with a spring-actuated locking pin or rod 12, carrying at its outer end a handle 11, the inner end of the pin adapted to engage the openings 16 in the plates 14, whereby the press and blow molds may be supported with their mouths downward, as illustrated in Figs. 1

and 2, or in the reversed position, with their mouths upward, as illustrated in Fig. 5, and

the said looking-pin 12 is adapted to hold the rotating tables 13, in these two positions.

Passing throughthe cylinder 18 is a pistonrod 19, carrying a piston-head 25, both ends of the rod extending throughthe piston-head, the lower end carrying a bottom 17 for the press-molds 5, the said bottom adapted to move within the press-mold when it is closed, as shown in Fig. l, the said press-mold haviug otherwise an open bottom.

Projecting upward from the base A is a standard J, carrying at its upper end a table 26, the said table adapted to rotate upon the upper end of the standard and carrying a pinrality of plungers l. Surrounding the lower ends of these plungers are the collars K, having upwardly-projecting arms 3, and situated below these arms are the springs L, which serve to normally hold the collars and the arms upward in the position illustrated in Fig. 1. Supported by the arms 3 is a springaetuated ring 2,; the springs 7 thereof tending to hold the ring to its seat in the mouth-ring .8, as illustrated also in Fig. 1.'

Each of the tables l3 also carries a'neckring8, made in two parts and hinged at their inner sides to a supporting pin or standard M,

the neck-ring being thus supported i-mmedi-' ately below the-mouths of thepressmolds, as illustrated Supported upon the base A at the chargero and-press? position, Fig. 3, is a cylinder 35,

carrying a piston-rod 40; which has its. upper end projecting through the upper end of the cylinder and carrying at its lower end a pisiton N. Situated below the cylinder is a I5 valve socket or chamber 29, which receives no der 35 and the valve socket or chamber 29' are cylinder for the purpose'of reciprocating-the piston-rod $0,:

an endwise-moving'valve P, and communicating-with this valve-chamber is a pressuresupply pipe Q. Forming communication betweeu'the upper and lower ends of the cylina the pipes R, the said valves being adapted to admit air alternately to opposite ends of the piston N, and consequently the 2 5 within the said cylinder for a purpose to be presently described." v

The plungers l have their lower ends loosely resting in the seat '1 of the rotating table 26,

whereby they are adapted to be lifted from c the said table by the upper ends of "the piston-rods 40. The lower ends of these plungers 1 are provided with sockets or openings a, registering with the openings b in the table 26, so that the piston-rod will move up 5 through the openings b in the table and the upper end thereof engage in the sockets 'or openings a of the plungers 1 and carry them within the press-molds, as illustrated in Fig. 1.

The table 26 is revolved through the me- .40 dium of a gear-wheel 27, surrounding the column 24, the said gear-wheel being attached to the base-plates 14 and supported by the depending arms 28, whereby when the table or collar 23 is rotated around the column the 5 gear-wheel 27 is correspondingly rotated.

The gear-wheel 27 meshes with stndsor projections 42, situated under the table 26, where-- by the table'is rotated one stepat a time to bring successively the plungers 1' under the so press-molds and the openings b in alinement with the piston-rod 40 of the cylinder 35. will be readily understood that instead of using four sets'of molds to rotate around the column, as illustrated in Figs. 3 and 4, live sets of molds could be used, and in this event to carry drop 'andto cause the air to be admitted to hereinafter.

43, adapted to move udder the rod andHhold. the valve normally in the position shown in:

Fig. 2, so that air or pressure is being normally admitted to the lower end of the -cyl-' inder for normally holding the piston-rod and the press-mold bottom'17 in an u prightpo'- sitionj, and whereby the bottom will 'retract I .u'nder' the pressure of the plunger after 'the mold is full-and permit the pluuger to always travel the same distance, and thus produce blanks with uniformbottoms, which produces when blown bottles with even and perfectly- -for med bottoms. Carried by the plates 14 is an arm 31, adapted to strike'the fingero'r plate 43'and move it from under the'lo'wer end of the valve-"rod 30, thus perm-ittin-giit to theupper end of the cylinder- 18.

Whenth'e machine has been placedlin posit-ion to be started by the setting of the'v'alv'e 30 through the medium of the treadle 32,

(which will be fully explained hereinafter,)

the" arm-31 serves-to-make the machine automatic in its operation in that whenthe ma-, chine is brought to the pressing position the said rod automatically'trips the valve-rod 30 and admits air to the upper end of the'c'ylim der 18 for carrying the bottom 17 to position,

and by the pressing operationthe bottom is automatically withdrawn in a. mannervto be fully described hereinafter.

A lever' 34 is intermediately pivoted to an arm f, projecting from the bracket C, one end of the lever being connected with the upper end of the valve-rod 30 through the medium of a link 35', and the opposite end of the lever is pivotally connected with the upper end of the rod or strap 33, which passes through the column 24. The lower end of this rod or strap 33 is connectedwith the treadle 32 at a point intermediate its ends, the opposite end of the treadle 32 being pivotally supported by an arm g, depending from the base A.

Connected to the upper end of the pistonrod19 is anarm 20,which has itsopposite and free end provided with an opening through which the upper end of .a rod 22 freely passes, K the lower end of therod being connected with a valve h, situated within the value-chamber 29, a spring 13 serving to hold the valve normally upward. Attached to the upper end of the rod .22 is a stop 36, with which the free end of the arm 20 is adapted toeng'age when drawn downward by the pistou-rod 19 in a manner and for a purpose to be described a spring-actuated pin 41, which is'adapted to engage a notch e in the lower end of an arm 21, which is pivotally connected at its .lower end to the lever 34 at a poin't between its fulcrum and the upper end of the valve-rod 30, the function and operation oi which will be presently set forth.

The arm 20 is connected with the upperend of the piston-rod 19 by means of a collar 74, and this collar is also provided with another arm j,which arm is adaptedto raise and lower .The rod 20 is also provided with from its seat by the upward movement of the piston-rod 19, all of which is fully understood by those skilled in the art and which does not therefore need any further description in this connection, it forming no part of our present invent-ion. l

The operation of our machine is as follows:

- The table 13 is in the position shown in Figs.

1 and 2that is to say, with the molds upside down. The table is then at the position marked charge and press, Fig. 3, and'the glass is placed in the open bottomof the pressmold. In the starting of the machine the valve 30'is set in the',position illustrated in Fig. 2 through the medium of the treadle 31, which admits air to the lower end of the cylinder, thus elevating the bottom 17, and when the valve 30 is released by the rod 31 it causes the valve 30 to admit air above the piston 45, and as the piston-rod 19 moves downward the free end of the arm 20 strikes the knocker or stop 36 of the rod 22, thus depressing the valve 72., which in its depressed position admits air to the bottom of the cylinder 35, which forces the piston-rod at) up through one of the openings b of the table 26 and engages one of the plungers 1 and carries it within the pressinold, as indicated in Fig. 1. The bottom 17 being in its lowest position when the free end of the arm 20 strikes the knocker 36 and the plunger serving to displace a part of the glass chargedin the press-mold forces the bottom 17 slightly upward. \Vhen the bottom 17 has reached its lowest position viz-hin the press-mold, the spring-pin -11 of the arm 20 engages the notch e of the link 21, and when the bottom is forced upward, owing to the insertion of theplunger 1 and the forcing upward of the glass charge, the

lever 34 has its outer end moved upward sufficiently to move the valve-rod 30 for admitting air below the piston 25, which carries the piston 25 upward and removes the bottom 17 from the press-mold. The upward movement ofthe piston-rod 19 releases the valve it through the medium of the arm 20 and knocker 3'6, and the valve is moved upward by the spring iand admits air to the top of the cylinder 35, thus carrying the plunger downward to its position upon the table 26' and the piston-rod out of engagement with the table. The table or collar 23, surrounding the column 2%, is t u rned to carry the pressmold, with its pressed blank, to the reversing position of Fig. 'lhemolds are then reversed by revolving the table 13, which carries them, first releasing the table by means of the rod 12 and handle 11, as before described. When the molds are reversed, the 'two parts of the press-mold drop downward into the position shown in Fig. 2 and the blow mold is closed around the blank, the blank being supported by the neck-ring 8. The pressed blank inolosed within the blow-mold is then carried to the blowing position, Fig. 3, and is there blown to the finished form, as is well'understood by those skilled in the art. .The pressed blank being blown to the finished form, it is then carried whilein'the blow-mold to the discharging position, Fig. 3,where it is removed andthe molds placed in 13 ready to be again charged when it reaches the charge-ai'ul-press position, Fig. 3.

It will be understood that when the pressed blank is carried from the charge-aud-press position to the reversing position the molds which were in the discharging position are carried to the charge-and-press position to be charged and pressed, and as the blow-head t is connected with the piston-rod 19, to which the bottom 17 of the press-mold is also connected, the blow-head is moved downward each time the bottom is, so that each time a blank is being pressed a pressed blank is being blown. The operations are repeated, so thatin effect when the table 23 has made one revolution a finished article is discharged at the dischargfrom one position 'to the succeeding position.

\Vhile we have shown the table 23 provided with four sets of molds, it will'be readily understood that it maybe provided with two or be reversed and blown and discharged at the reversing position or the molds could be subjected to the. blowing and discharging operaprefer to use the charge-and-press, the reversing, the blowing, and the discharging positions all of these positions are not absolutely necessary and could. be omitted without departing from the spirit and scope of our invention. v

While the tables 13, which carry the press and blow molds, are rotatable, it will be noted that. they only necessarily move halfway around to accomplish the reversing of the molds, so that the table may be merely oscil cut, is-

ing position at each movement of the molds more sets of molds and that the molds could tions at the blowing position, so that while we 1. A machine of the character described comprising reversible press andblow molds,
