To Irl/,mil if 71mg/ concern.-

Be it known that I, EDWARD S. HUTTON, of Lapel, county of Madison, and State of Indiana, have invented a certain new and useful Machine for Making Glassware; and I do hereby declare that .the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention relates to continuously-operative glass-machines.

The object of' this invention is to improve the construction and operation of automatic machines for making hollow and pressed glassware-such as fruit-j ars, large-mouthed bottles, and the like-where plungers are employed. The molds may be of any suitable form', and any number of molds and plungers maybe employed, although only four sets are herein shown, for convenience, and while the machine is, as a rule, run continuously, means is provided herein for stopping it, when desired, at mold-charging positlons.

Onevfeature of this invention consists in mounting air-Cylinders on a revolving plunger-table and means in connection therewith for operating the plunger and supplying air thereto from a stationary central compressedair pipe, said mechanism having suitable valves for 'regulatingr the operation of the same, that are controlled by means mounted in connection with a stationary frame above'.

Another feature of the invention consists in means for operating the blow-head for revolving blow-moldsand in supplying air thereto from said central air-tube, and in combining this feature of the invention with y that set forth in the above paragraph, and

roviding a vertically-adjustable frame with suitable means depending therefrom for controlling both the plunger-operating mechanism and the blow-head-oper'ating mechanism.

Another feature consists in the means for mounting and operating false molds in connection with revolving molds, and in providing an air-cooling means adapted to cool said false molds, plungers, and other parts when the machine is stationary, and in providing means for intermittently stopping the revolution of the machine by engaging stopnotches in the mold-table with a pedal or other suitable means.

These and the other features of this invention will be understood from the accompanying drawings and the following description and claims.

Figure 1 is a side elevation of the machine with parts broken away. Fig. 2 is a front elevation of the machine with many parts figure showing especially the molds and plungers and means for mounting and operating the saine, the when actuated and its associated parts being shown in dotted lines. Fig. 3 is a central vertical section through the plunger-operating mechanism, showing the plunger elevated.

tical section on the line 17 17 of Fig. 1, parts omitted and some parts broken away, said side of the table`33. A A mold-bottom 45 revtion in said bar 38.

Fig. 1, the central air-pipe being in section.

. are suitable molds formed o1 the sections 34,

provided with means 35 for o ening and closing the same. The sort o mold and the means for opening and closing it are immaterial to this invention. rIhere is shown, however, a mold for making fruit-j ars with screw.- tops. The mold-sections are pivoted to a bolt 36, which is secured in the .plate 37, fastened to the table 33, andthe molds are held down at the front bya bar 38, that engages a projection 39 from the lower part of the moldsections that extend into the undercut por- (Shown by dotted lines in Fig. 9.) The molds are mounted over a radial opening 40 in the table, through which a false mold 41 and its stem 42 reciprocate. The stem A42 operates through a guide 43, that is secured by the bars 44 to the under ciprocates horizontally in the opening 40 into false mold 41 has a notch and out of position under the mold. Safid bottom has at each end buffers 46, and a pin 47 extends down from said bottom, whereby it is moved. Said bottom reciprocates on the plate 48, (seen in Fig. 5,) which is fastened to the under side of the table 3 3, under the slot 40, as seen in Fig. 9. The stem42 of the 49 in it, as seen in Fig. 5, which is engaged when the false mold is 1n its upper position by a horizontally-ro- 51, that is in the ears 52 of the guide 43.

As the mold-table 33 is revolved the false molds are elevated by the inclined track 55, (shown in Fig. 2,) formed of spring metal and secured at one end tothe base 30I and supported by the post 56 about midway, and under the upper end there is :a spring 57. The stem 42 carries a caster 58 at its lower end for traveling on said track. The material of which the track is made permits it to yield slightly in order to provide for the inaccuracies in the construction of the molds and parts. Whenin itselevated osition, the arm 60 engages the locking-w eel 50 and turns it into locking position, as above described, so that said locking-wheel will hold lthefalse mold in its upper position. Said arm 60 is vadjustably secured to the track 55 by set-screws 61,- extending throu fh slots in` the lower parts'of the arm. Anot er tracksection 62 'is mounted onv supports 63,'secured to the base in a horizontal position, one endv of. Said jtrack-section.62 being substantially under-'the elevated end of the section55. This second track-section 62 is tio Y receive the stem .4.2 of the false mold when it drops. As the table 33 revolves, the locking- .bars

wheel 50 is engaged by the upper end of the secured to the track 55. The further rotation of the table 33 causes the stem 42 of the false mold to run oif the end of the track-section 62 upon the inclined foot 65 of a trip 66, said parts being mounted on a pivot 67 in a bracket 68, secured to the base. The trip 66 is held in the dotted -line position shown in Fig. 2 normally by aspring 69, and it is actuated in the manner just described. Said trip at its upper end engages thepin 47, extending downward from the movable bottom 45, as heretofore explained and as shown in Figs. 1, 2, and 9. ln this wayl the movable bottom is moved from the position shown'in Fig. 9 to a position under the mold." After the false mold has descended and after said bottom is thus moved intov position the glass is ready to be blown in the mold 34.

Turningnow to the plunger mechanism,

there is"what may be called a plungerset-screws 73. and secured to and spaced from the mold-table 33 byfour pairs of brace- 140. Said tables are rotated by the tubular shaft 72, to which they are .both secured by the set-screws 73. Said shaft. 72

Ais actuated by a bevel-gear 74 at the top .and

it in turn by a bevelvinion 75 on a shaft 76, that .is mounted in from a top frame 78 and driven by a frictionpulley 79. Upon the table 70, as seen in Fig. 2, there are plunUer-cylinders -80 secured, which, as shown in IFigs. 3 and 4, are provided with pistons. 81., plunger-rods 82, with plungers 83 at their lower ends. There is one of these plunger mechanisms over each mold andl positioned so the plungers will enter the corresponding molds as they are successively moved downwardly. lThe tion of one of these plungers is shown in 4the lefty half of Fig. 1 and in dotted lines in Fig. 2 and the upper position on thev right-hand side of Fig. 1 and also in lug. 2. The cylinder 80 has an upper port 84 and a lowerv port85, to which compressed airis admitted alternately throughair- chambers 86 and 87 from a valve-chest 88 by the-,slide-valve 89.

The valve 89 hasa lower guiding-.stem 90 and "during the revolutions of the table- 70 moves over and is elevated byan inclined b a-r` 96, secured to a from the top frame 78, as seen in Fig. l1. lbar 96 elevates the wheel and depresses the slide-valve 89 to the position shown in Fig. 4, and during Such downward move-k vl`v`ment of sald vvalve the. plunger 1s driven vdownward -into the mold. This position is shown by dotted lines in Fig. 2 and in Fig. 1

also, although in the latter figure the\roller 95 is moved somewhat away from the bar 96. Soon afterward as the table revolves said roller engages an inclined bar- 98, that extends downwardly from the top 78, as shown in Fig. 1, and by it said roller is depressed and the slide-valve 89 moved into the position shown in Fig. 3, whereby the plunger 83 is elevated. Thus it is seen that in both positions of the slide-valve 89 the air is exhausted from the cylinder through the exhaust-port 99 in said valve and 100 in the valve-casing, the latter appearing in Fig. 2. The ports 84 and 85 are regulated by the screw-valves 102, which by being screwed manually adjust the dimensions of the port-s as desired. Compressed air enters the valvechest 88 through a tube'104, leading from a short pipe 105, that is screwed into a band 106, surrounding the stationary air-pipe 110, so as to turn. thereon. Said band has an annular air-chamber 107 in it, which receives air from pipe 110 through ports or holes 108 in said pipe. The band is held in place by clamping-collars 109 on the ends of the band, with suitable packing between them and the band to prevent thel escape of air. The lower clamping-collar 111 is secured. on the upper end of a hollow shaft 102. Thus air is continuously supplied from the pipe 110 to the valve-chests of the various plunger-cylinders through the tubes 104. Compressed air is supplied to the pipe 110 from any suitable source, said pipe being stationary and secured to the top frame 78, which is mounted on posts 112, that extend up from the base of the machine.

The 'blowing mechanism will now be described. A rubber tube 115 leads from each pipe 105 to a blow-head116, that is adapted to be moved into operative contact with each mold, and-thus furnish air under pressure in said mold for blowing the glass. The means for bringing this about is shown in Figs. 10 to 16. A plaie 117 is fastened upon the plunger-table 70, as shown in Fig. 10, said plate 117 having a hollow post 118 extending upward therefrom. A shaft 119 is mounted in said post 118, as shown in Fig. 11, it having a groove-120, as seen in that figure and also in Fig. 12, into which a keyv121 extends, and that is held in place by the set-screw 122. The main portion of the groove 120 is vertical; but at its lower end it has a horizontal port-ion forming a shoulder 123, under which the key 121 catches when the shaft 1 19 is in its elevated position. Said shaft is in its upper position in Fig. 10, and in such position the blow-head 116 is in full-line position, (shown in Fig. 10,) it being carried by an arm 124 from a sleeve 125, that is adjustably mounted on the shaft 119 by a set-screw 126.

As the table 70 revolves, a curved pin 128 on. ofthe shaft119 engages an' the upper end arm 129. extending downwardly from the top frame 78, and thereby the shaft 119 is turned so that the shoulder 123 will move 0H the key 121, and the vertical portion of the slot 120 will permit the shaft 119 to drop by gravity, and the blow-head 116 and dotted-line position (shown in Fig. 10) and upon the mouth of the mold.

The blow-head, as seen in Figs. 14 to 16, carries a valve 130, with a hollow stem 131 extending upwardly from a valve-plate 132, 7 5

that fits loosely in the lower part of the blowhead. The stem 131 is long enough to have some play in said blow-head, as' shown in Figs. 14 and 15. When the blow-head drops on the mold, as shown in Fig.` 15, the plate` 8o 132 rests upon the mold, and the blow-head drops down upon said plate, so as to openthe valve and admit compressed air from the pipe 115. When said blow-head is elevated,

it is automa'.ically closed by the air-pressure. 8 5

Said blow-head is elevated from the mold by an inclined track 135, secured to the arms 136, extending downward fromthe top frame 78, as shown in Fig. 10, upon which a roller 137, secured 119, rides. As the wheel 137 runs on the track the pressure of said track against said wheel, since said wheel is to one side of the verticalv afs ofthe partially-rotatable shaft 119, will cause said shaft to partially 95 rotate from the middle position shown 1n Fig. 10 to the position shown at 'the right hand of Fig. 10, so thatwhen the shaft 119 is elevated it will be turned 'by such lateral pressure of the track 135 sufficiently to cause roo he shoulder 123 to ride upon the key 121, and during the remainder'of the revolution of said shaft it will be held in such upper position until the gravity-pin 128 can engage the arm 129. ated by a friction-pulley like 79 orV any simllar mechanism, it is stopped by the free end of the pedal engaging one of the notches 151 in the under side of the table 33. There are four of these notches, arranged so that the I 1ol table will be slopped at the point and time of charging each mold. In Fig. 1 the mold marked X has been charged and the machine has just been started, the left-hand notch 151 f having moved some distance away from the 1 i 5 pedal 150, and during that, movement the, plunger has operated. The pedal 150 is fulcrumed in the upper end of the. post 152, and it is pressed upwardly by a spring 153 around a pin 154, operating through a stand-plat- 12o form 155, that is supported on apost -156 and fastened to one of the posts 112.

The operation of the machine is normally constant; but it may be intermittent and be stopped at each fraction of revolution by 12 5 the pedal 150 for the charging of the mold. After charging the mold with glass the pedal 150 is depressed, which permits the machine to start and the table 33 to revolve. Immediately thereafter the plunger is actuated by 13o will be in the lower 7o to the upper part of the shaft 9o Zhen this machine is oper- 1o 5 moved off the track-section 62.

. charged and the article the bar 96, causing the admission of air to the plunger-cylinder. Immediately the bar 98 at the top causes the reversal of the actuation of the plungermechanism whereby it is withdrawn from the mold. Then the false mold descends, the stem thereof having Then the trip 66 is o erated by the downward movement of sai stem, lwhich slides the mold-bottom into position under the mold. Very soon thereafter the bar 129 pushes the shaft 119 around and causes the blow-head to settle down on the blow-mold, whereupon the alve 130 is opened and the glass blown: Then the wheel 137 travels up on thel track 135 (shown in Fig. 10) and at the end of said movement is turned somewhat, so as to turn the blow-head and enable the same to be held in its elevated position. After that the mold is opened and the completed glass jar Y, as shown in Fig. 1 at the right hand, is ready for removal. As constructed the mold is pressed by the plunger and blown into final form and cooled durin about one-half revolution of the mold- After the article is removed the mold has still a half-revolution for cooling. The false mold cools for almost the entire revolution.

The plungers and false molds es ecially and. thel other molds are cooled by b asts of air from the nozzles 160, extendingfrom the tubular posts 112. There are four of these posts, near which the molds and plungers are situated while the machine is stopped and the nozzles are directed toward the parts to be cooled. The tubular posts 1 12 are charged with air from some suitable source of sup ly through the pipes 161 and 162. The mo dbottom 45 is moved from under the moldby a curved or cam-shaped piece 17 5, secured to the turn-table plate 32 by the arm 176. As the mold-table revolves the pin 47 from the mold-bottom engages the curved surface of the piece 175 and is thereby moved radially inward, as shown at the right hand of Fig. 2.
