Specification of Letters iatent. Patented Sept, 9,1913,

Application filed March 16, 1912- Serial No. 684,120.

E. WINDER, a citizen of .the United States, residing at VValtham, county of Middlesex, State of Massachusetts, have invented a new and useful Automatic Bottle-Blowing Machine, of which the following is a specification.

This invention relates to the art of manufacturing glassware, and more particularly to the automatic pressing, molding and blowing glass bottles, and has for its object to provide a machine wherein the several steps necessary for the formation of a bottle from the gather of glass are performed within the machine entirely automatically, and the only manual operation necessary is the placing of the gather of glass within the press mold of the machine.

It has for a further object to provide a mechanism for automatically cutting the gather of glass after it is placed within the press mold, producing a partial vacuum within the press mold sufficient to draw the gather of glass into the mold and form the neck of the bottle, cause the operation of a mechanism to punch an initial opening inthe neck of the blank and thereafter admitair to give a preliminary blowing to shape theblank, next automatlcally removing the blank from the press mold and maintaining it in an inverted position and bringing it in the same position into the blow mold.-

where the blowing mechanism operates thereon to form a completed bottle and then providing an ejector mechanism for'successively removing the finished bottles from the machine.

It has for a further object to provide a novel air valve mechanism whereby air under pressure is controlled and delivered at predetermined times to the different parts of 'the machine for ,causing the completion of certain steps in the process of formingand blowing the articles.

It further consists of other novel features of construction, all'as will be ,.hereinaf-ter'i.

fully set forth.

For the purpose of illustrating my inve ns tionji il have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be under- 6 that the various instrumentalities of" .3 invention consists can be variously being omitted to avoid confusion.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates the base-of a machine for molding and blowing glass bottles and like forms and-carrying thereon a column 2 preferably centrally disposed with respect to the base 1, and having a flange3, by means of which it is secured by bolts 4 or like fastening devices to the aforesaid base 1. The flange 3 as here shown, is

. provided with a circular groove 5 substan-' tially concentric with respect to the column 2 and serving the purpose of a ball race in which are located a plurality of ball-bearings 6, which latter fit into a similar ball race 7 formed in an annulus 8 fitting around the column 2. This annulus 8 is provided on its outer periphery with worm teeth 9 and is also formed with a beveled countersunk por tion providing a friction face 10 with which a ring 11, havinga cone face 12 thereon, is adapted to coact. This ring 11 is secured by means of-k'eys or pins 13 to a hub 14 whereby it rotates therewith but may have a sliding movement relative thereto, if desired. It being noted that the two faces 10 and 12 are frictionfaces, and are firmly held together by means of the spring 15. The function of this construction is to provide a fric tion drive for certain elements presently to be described, and which are attached to the hub 14 so that at certain times when the friction 1s overcome, the ring 11 will cease to rotate.

The driving mechanism for the annulus 8 comprises, in the present instance, a worm 16 fixedly mounted on a shaft 17, the latter having sintable bearings 18 and carrying thereon a sprocket 19 driven by a sprocket chain 20, from a sprocket 21 mounted on the main shaft 22. The shaft 22 is of course driven from any suitable source of power from the pulley 23 and is adapted to operate continuously.

' 24 designates the press mold table which,

in the present instance, forms an integral part of the hub 14 and carries thereon a plurality of cylinders 25, fixedly secured thereto by means of bolts 26 or the like, which are also secured by similar bolts 27 to the blow mold table 28, here shown as located a suitable distance above thetable 24. It will thus be apparent that motion transmitted from the annulus 8 to the hub 14 will cause both tables to rotate about the column 2. The table 24, in the present instance, is provided with a plurality of openings 29 adapted to receive a tubular member 30 having asupporting flange 31 thereon by which it is properly suspended from the table. lower end of this member 30 is closed by a cap 32 into which is threaded a sleeve 33,

engaged by an exhaust-head, presently to bedescribed, whereby a vacuum is created in the space 36 to cause the desired suction through the ports 35 and 37 whereby the gather of glass 40 is drawn into the press mold.

41 designates a bushing secured to the sleeve 33 and serving to guide the plunger 42 during the initial step of punching an opening in the neck of-the gather 40. This plunger 42 is slidingly mounted in the sleeve 33 and embodies a piston valve 43 closely fitting the bore of the sleeve 33 and controlling the opening and closing of a port 44 for the admission of air under pressure. The piston 43 has a stem 45 secured thereto, project- 7 The are normally held retracted as shown in Fig.

20. The operation of the plunger 42 is effected, in the present instance, by a cam track or way 48 secured to .the fixed base 1 and in the path of movement of the head 46.

49 designates a guide plate, fixedly secured to the table 24, having a central opening 50 to receive the flange 31' of the member.30 and end slots 51, these latter beingalined with openings 52 in the table 24 in order to permit the studs 53 to pass therethrough and bring the cam rollers 54 into operative relation with the cam grooves 55in the disk 56. As shown in Fig. 8, each 56 has a cam groove 55 at each end while a central aperture 57 allows the disk todit over the tubular a the disks 56 is to open and close' the press molds 38 at the desired times an'doscillation of the disks 56 is effected by providing each with projecting lugs 60 adapted to be engaged by stationary trips 61 at the proper time. Movement of the disks 56 is transmitted to the press molds 38 by means of posts 62 mounted on base members 68 and to which the studs 53 are connected. The posts 62 are slidingly mounted in the guide plates 49 and are connected by links 6 1 with the press mold sections, it being noted that these sections 38 are formed with ears 65pivoted on a spindle .66 which is fixedly secured, in the present instance, to the guide plates t9.

It will be apparent that when the disks 56 are shifted that a corresponding movement of the press molds will take place, they being either opened or closed as the case may be. Assuming they have been closed about a gather of glass, as shown in Fig. 19, a suction is produced in the space 36 which through the ports 35 and 37 draws the glass into the mold. lVhile the glass is thus held by suction, the plunger 42 is operated, through the head 46 meeting the cam track 48 and a preliminary opening punched in the glass. On'leaving the cam track 18 the plunger 42 is withdrawn and a blowing step takes place which produces the effect shown at 07 in Fig. 20.

(i8 designates a frame suitably carried, in the present instance by the base 1 and carrying a cross head 69 in which is slidingly mounted a cam 70, having connection with the piston 71 of a cylinder 72. This cam 70 coacts with a roller 73 carried by the latch bar 7 4, the parts being maintained in proper engagement through the medium of a spring 75 which is secured at one end to the bar 74 and at the other end to a fixed portion of the frame 08. This latch bar 74 is normally held engaging one of the notches 76 formed in the edge of the table 24 and by which the table is locked after making a partial rotation. The latch bar 74: is withdrawn from its locking position by a movement of the cam 70 which is effected by admitting fluid pressure into the cylinder 72 by way of the conduits 77 and 78.

79 designates a three way control, valve for the pressure fluid and the position thereof controls the flow of pressure fluid to the conduits 77, 78 and blow head 101. The operation of the valve 79 is effected by a foot treadle 80 operating through suitable link connections 81 and held in normal position by means of the spring 82. 1'.t is desirable to provide a means to lock the treadle 80 for a predetermined time, and for this purpose Iutilize acatch 83 suitably pivoted adjacent the treadle 80 and having a spring 84: connected to a fixed part, as the bracket 85, by which the catch 83 is drawn into locking position above the treadle 80 when the lathe is depressed. In order to release the catch 83 I preferably employ a pin 80 slidingly mounted on the head of cylinder 72 and projecting interior thereof so that when the piston T1 descends will strike the said pin 80 and causethe catch 83 to be swung 65 back, thereby releasing the treadle 80 which is shifted by spring 82 to again operate the valve 79.

87 designates a-cylinder suitably mounted on the frame 08 and embodying the piston 88 and rod 89 which form the operating means for a plate 90 slidingly mounted on the table 91 and adapted to be reeiprocated by the movement of the piston 88. The cylinder 87 received pressure fluid through the pipes or conduits 92 and 93, the same being respectively connected to the conduits 77 and 78. The plate 90 carries thereon a pair of rollers 94 suitably spaced apart to receive the cutter blades 95 which are pivoted at 96 and have end portions formed as wiper cams 97 adapted to engage the rollers This movement of the plate in one direction causes the cutter blades to close while the opposite movement opens them.

It will be noted that these cutter blades 95 are so positioned that when the table 24 rotates and brings a press mold adjacent the frame (38, the top of the said mold will be directly beneath these cutters with the mold opening axially alined with the meeting edges of the blades. 1

98 designates a suction head suitably mounted on the frame 08' and adapted to be connected to a pumping element or the like for producing-the desired vacuum. To the head 98 a lever arm 99 is connected havinga slot and pin connection 100 with the latch bar 74 so that movement of the latter causes the head 98 to move toward or away from the tubular member 30. When the head 98 is moved to engage the member 30, it alines with the port 89 and thus produces the desired vacuum for drawing the gather of glass into the press mold.

101 designates a blow head suitably secured to a link 102 which is pivoted on a bracket 103, and operated by a fluid motor 104. Air is supplied to the head 101 through the conduit 105 and the parts are so positioned and controlled as to come into opera tion just after the glass in the press mold has received the initial punching by plunger 42. Thus the gather of glass will be inserted, cut and punched at station A Fig. 12 and then the latch bar 74: will be withdrawn permitting the table 24 to move, say one-eighth of a revolution, to station B.

At this station the blow head 101 is brought the respective mold sections.

posed on the table in a corresponding manner to the press molds on the table 24, and therefore a description of one of them should suffice for all. Referring first'to .the mechanism for bringing the glass blank from the press mold table to the blow mold table, 107 designates. a bottom former-havinga plurality of ports 108 therethrough which communicate with the interior ofthe tubular stem 109 to which the former isattached. This stem 109 is fixed toa bracket 110 of the member 111 whichis-mounted-for slid-.

ing movement on an upright 112 carried by the table 28. The member 111 is also provided with an'ear 113 by means of which itis fixed to the piston rod 114 connected to piston 115 within cylinder 25. By this construction the head 111 may be raisedor lowered, thereby carrying the bottom former 107 down through'an opening 116 in the table 28 into engagement with the-blank in the press mold as shown. in Fig--20? .The pressure fluid for operating'the piston 115 is conveyed by pipes 117 and 118-to the respective ends of the cylinder 25, the said pipes being connected to a main control valve presently to be described.

, 119 designates a blow mold formed in sections each of which is pivotally mounted on the spindle 120., which latter is aflixed to an apertured plate 121 resting on the guide plate 122. This guide plate 122 is provided with a central opening 123 and is slotted at each end as shown at 124 to receive the blocks 125 which connect by links 126 with Each block 125 carries a pin 127 fitting Within a cam groove 128 at each side of the "cam plate 129, whichlatter is centrally apertured to form a bearing on the central hub 130 of the guide plates 122. The care plate 129 is pref erably moved in one direction by a pressure controlled motor-.131 to which the pressure fluid is admitted at thedesired moment, and in the opposite'directionby a suitable tt'ip mechanism hereinafter described.

132 designates the blow heads of which in the present instance there are four, each beinto engagement with an ingsuitably pivoted at 133 to a cylinder 25 so that they may be swung independently to aline with the respective blow mold openings. y

134 designates a lug or pin secured to each cam plate 129 and projecting, through a suitable curved slot 135 in the table 28,

elongated opening 136 formed in the extension 137 of each blow head 132. .By this construction movement of either the cam plates 129 causes the corresponding blow head 132 to be swung either into or out of alinement with a blow mold opening. In order to admit air to the blow mold heads 132; a port 138 is formed in each havingcommunication by way of a flexible pipe or tube 139 with its adjacent to operate certain parts hereinafter to be de scribed.

.Referring now to the main air control mechanism, attention is first directed to the fact that in my preferred construction, the column 2 is utilized as achamber for the exhaust from the several cylinders 25, and

it will be noted that its upper end adjacent the table 28 is provided with a pair of channels 142 and 143 with which the air pressure pipes 144 and 145 communicate respectively, the said pipes passing interiorly of the column 2 and through a sleeve 146 whieh is secured, in the present instance, in a vacuum chamber 147.

l48gdesignates a plurality of exhaust ports formed in the column 1 2 and preferably alined'with the inlet channel 142.

149 designates a second row of exhaust ports in the column 2 adjacent the inlet channel 143. The two'channels 142 and 143 communicate respectively with and are connected to the pipesv 144 and 145 by means of the inlet ports 150 and 151.

152 designates a collar towhich the cylinder supply pipes 117 and 118 are connected and through which they pass in order to form communications at certain times with the respectiveehannels 142 and 143 and the exhaust- ports 148 ,and 149, it being under stood that'thiscollar fits over the column 2 and is seated upon the table 28, being retained in this position by means of a retaining ring 153, which latter is fixedly secured to the column 2 by means'of set bolts 154, or like fastening devices. It will thus be apparent that as the table 28 rotates, it carries the collar 152 with it and thereby successively brings the two pipes 117 and 118 into positionto receive air under pressure and operate one of the pistons in one of the cylinders for one movement, and then as this pipe 117 is brought into position to exhaust by way of ports 148, a second pipe 118 will be receiving air. under pressure from channel 143, and it in turn will exhaust through the ports 149 as the collar 152 continues its movement.

The vacuum chamber 147 communicates by way of the ports 155 in the sleeve 146 with the interior thereof, and it will here be understood that this sleeve is closed. at its inner end and is connected by means of to lette I I i 6 f the ipe 156 within suitable suction device. as will be understood.

In explaining the operation of the machine, the several steps in the formation of a single bottle will be followed, as it will be understood that each unit of the machine performs its functions independently, and in the present machine, four operations are going on simultaneously, thus one unit is cutting and punching one bottle blank; another unit is forming an initial opening in a second blank; another unit is blowing a third blank, while another unit is discharging a completed bottle.

The drivmg annulus 8'is first connected with the source of power and therefore the two tables 24 and 28 and column 2 are ready admit air to the to rotate as soon as the latch 74 releases them, since of course the friction member 12 is contacting with the annulus 8 and tending to rotate.

With the parts in the' position shown in Fig. 12, the operator drops a gather of glass into the opening of the press mold 38 and at the same time presses the treadle 80 until, it is held by the latch 83. The position of the press mold at this time is such that the suction head 98 connects with port 44 and the glass is therefore drawn quickly into place. The lowering of the treadle 80 causes the three way valve 79 to turn to cylinders 72 and 88, the former shifting the cross head and the latter operating the cutters 95 which sever the glass close to the top of the press mold. The downward movement of the cross head 70 withdrawsthe latch bar 74 and cuts off the suction from head 98. The table 24 is therefore released and turns through approximately one-eighth of a revolution. 'At this point the crosshead 70 has lowered far enough to allow the spring 75 to return .the

latch bar 74 so that it engages the next notch 76 and again locks the table 24. Furthermore, the piston 71 has at this time struck the pin 86 to release the treadle 80 and the return movement of this member under the 4 influence of spring 82 again shifts the three way valve 79 and causes air to be delivered to the blow head 101, which in the meantime said former.

It is now time has been brought up to port 44 through the operation of motor 104. The press mold 38 in passing from its initial position tothis one eight-h position has; passed over the cam 48 and the plunger 42 has been forced upwardly to form a preliminary opening in the blank.

, Referring now' to the upper table 28, .the step of lowering one of the bottom formers 107 has taken place while the foregoing operations have been effected. The collar 152 has rotated one-eight of a turn and brought pipe 117 into communication with the port 142, thus admitting air to one, cylinder 25 and causing piston 115 to lower and bring the said former .107 into contact with the glass blank as illustrated in Fig. 20. It is in this position that air is admitted through port 44 to blow the opening 67 and press the blank firmly on the former 117, 'whereit is held secure by the vacuum produced in the Afterthis step, the table 24 is automatically released, by the upward movement of cross head 70, which of coursefollows from the valve 79 having been shifted by the disengagement of latch 83 as heretofore described, and thereupon moves another eighth turn, brifrgingthe blank to station B. At this station the press mold 38 is automatically opened by" 'th'e engagement of the lug 60- with the stationary trip. 61. for the bottom former 107 to conveythe blank to thfblow mold table 28. The collar 152 is therefore in position to exhaust the upper end of" cylinder 25 through ports 14S and admit air to the lower end by way of ports 143: and pipe 118 so that the former 107 moves upwardly carrying the blank into position within the blow mold 119 at station B. The movement of the table 28 from the station B brings the nipple 188 in collar 152 into alinement with port 185 so that the motor 131 is operated to close the mold about the blank and when station C is reached, the blow head 132 is positioned as shown in Fig. 11 and air enters the. blank and blows the complete bottle. From station C the blow mold moves to station D where port 185 alines with exhaust port 192 and port 186 alines with inlet 191 so that motor 131 is again operated, but in the reverse direction and the blow mold is opened. As soon as the mold opens, the

.vacuum ejector arm, 160 swings up automatically and grips the bottle which it then removes and delivers to a suitable point. As this ejectorv action has already been described in detail it is thought unnecessary to here repeat the several movements.

It will nowbe apparent that I have devised a' complete unitary structure well adapted for the purpose intended and which is simple in construction, positive in operation and automatically carries out a series of steps, one following another, and all coneases in-Hing in a complete cycle which begins [with a gather of molten glass and ends with a completed article delivered to' a suitable int. 4 It will now be apparent that I have de vised a novel and. useful construction of an automatic bottle blowing machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, itis to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of thein vention or sacrificing any of its advantages.
