The invention illustrated has a bed 1 supported by which are vertical columns 2 that are connected at their upper ends by a cross beam 3 (Fig. 1). A table 4 carrying the de sired number and style of molds'5 is mounted on suitable bearings 6, (Fig. 5) so as to rotate about each column, and a pressing mechanism 7 for each table is supported by the overhead cross beam above the paths of the molds. The machine is actuated by the rotation of a drive shaft 8 which extends horizontally from side to side across the machines above the bed and drives both machines. As the table rotating, plunger reciprocating, and interlocking and controlling mechanisms of the two machines are similar, only those for the left hand machine are herein illustratedand describedin detail.

The table is intermittently advanced by the following mechanism. Mounted on a vertically held stud 9, Fig. 5, above-the bed and below the table near. one side of the machine, is a Worm wheel 10 that is engaged by a worm 11 on the drive shaft. Keyed on the hub 12 (Fig. 5) of this worm Wheel are two .

cams

13 and 14. The cam '13- acts against a roller 15 (Fig. 2) carried by a rocker yoke ]6,the hub 17 of which is mounted on a vertical post 18 supported by a frame 19 fastened on the bed near the back of the machine, (Figs. 2, 7 The cam 14 acts against a roll 20 carried by the rocker-yoke to hold back the table as it approaches its stopping position, overcoming its momentum and preventing it from passing its stopping positions, also to insure positive return of the rotator parts. A spring 21 is arranged to hold the rocker roll 15 back against the cam 13. The other end of the sprin is attached to an arm 143, which is adjusta 1y clamped on the part 144, the upper end of which is connected with the top of the stud 9 by a brace 145. Mounted on the post 18 and adjustably fastened to the hub of the rocker yoke is a rocker arm 22, (Figs. 2, 7,)-which is connected by a link 23 with a table rotator arm 24 which is pivotally mounted on the hub 25'of the mold table 4 (Fig. 2-, 5). In the end of the rotator arm is a bolt 26, a spring 27 being arranged to normally project the bolt outwardly from the arm, into one of the index notches 28, formed in the inner sides of index blocks 29, fastened to the'under side of the table at equal distances apart around the table, (Figs. 5 and 6) herein shown to be eight in number spaced 45 degrees apart, for tables carrying eight molds. In normal operation the bolt 26 is projected into a notch 28 and the rotator arm is swung forward 45 degrees, advancing the mold table one step; Then the bolt 26 is positively withdrawn, and the rotator arm is returned to its first position, with its bolt in line with the next notch.

These notches are also engaged by the looktive movement of the table and the rotator.

mechanism, thus enabling the rotator bolt to be utilized for advancing the table by a graduated movement which is first accelerated and then retarded. Mold tables, especially when loaded with molds, are externally heavy, and for commercial production it is necessary to advance the table in a very short time, from one to two seconds. To make this rapid advancing movement smoothly without shock or jar, it is desirable to start the table slowly, accelerating its speed for about half its movement, and then retardin its speed and stopping it at its next 100 ing position. The rotator mechanism here shown is adapted to impart such a controlled advancing movement during which the relatively slight taper of the bolt 26 enables it to remain seated in its notch 28 against the displacing tendencies of the accelerating and retarding action. The rodex notch 28, the first accelerating half of the advancing movement is imparted by the cam 13 against the roller 15. The momen; tum of the table would ordinarily carry from this point, past the next stopping pos'l tion. Therefore during about the last half of its movement the table is retarded, so as to stop without shock approximately at its index locking position. This retarding movement is effected by the cam 14 operated against the roller 20, assisted if necessary by brake mechanism, as hereafter described (Figs. 10 and 11).

Inasmuch asthe

bolts

26 and 40 are not self retracting from their notches 28 for the reasons above described, other means are provided for positively retracting those bolts and also for controlling their positions at all-times, independently of the notches 28, and these rotator and bolt controlling mechanisms are so coordinated and interlocked as to insure their proper operation under normal conditions, while also safeguarding the machine against injurious operation under abnormal conditions.

For retracting the rotator bolt. 26 and controlling its osition at all portions of the forward and backward movement of the rotator arm, a segmental controller 36 is mounted for horizontal swinging movement on the vertical stud 37. The inner guiding surface of the controller 36 engages with a roll 38 on a stud 39 secured to the under side of the rotator bolt 26 (Figs. 2, 3, 4 and 5). When this controller is in a position which retracts the rotator bolt (Figs. 3 and 4) its inner guiding surface is concentric with the axis of the table, so as to hold the bolt in retracted position throughout the returning movement of the rotator arm. The arcformed by the guiding surface is slightly longer than the arc of swinging movement of the rotator bolt roll 38, so as to control the sliding movements of the rotator bolt throughout its entire are-of swinging movement.

The rotator bolt controller 36 is operated normally by the following mechanism :.A

worm 30 on the drive shaft 8 meshes with the worm wheel 31 on a vertical cam shaft 32, which is supported by a bracket 33 mounted on the bed below the table. A spider 94 supported by the

posts

44, 95 and 96 forms a bearing for the upper end of the cam shaft 32. Fastened to this shaft are the control cams (Figs. 8 and 9). The cam 34 engages with the roll 35 on the rotator bolt controller 36, and swings the latter to the extent shown by comparison of Figs. 2 and 3, this movement being timed in proper relation to the forward and back movements of the rotator arm 24, so that in the normal rotator bolt 26 in its retracted position durljing thatmovement, thereby preventing it from enteringany succeeding notch 28 until it again reaches its backward position shown in Fig. 2. Figs. 4, 15 and 18 illustrate a condition in which the table is. displaced from normal position, by handmbl otherwise, and shows how the controller 36 prevents the bolt 26 from entering the notch 28 in front of it. It will be understood that both of the rotator arms 24 continueto oscillate while either machine is in operation.

The table is locked 1n position at its different stations by a lock bolt 40 which is slidable in its seat in the upper end of a fixed bracket 41 that is mounted on the bed at the front of the machine. A spring 42 is arranged to pull the bolt outward so that it will enter one of the notches 28 on the underside of the table (Fig. 3). This lock bolt is withdrawn at the proper time to release the table, by the angle lever 43 that is mounted on a post 44 of the frame 33. One end of this lever is forked and engages a stud 45 projecting from the bolt, while the other end has a roll 46 that is held by its connection with the spring 42 in contact with the periphery of the cam 47 on the shaft 32, (Figs. 2, 3, 4). In the ordinary operation of the machine the lock bolt is withdrawn from a notch 28, and about the same time the rotator bolt 26 is allowed to enter another notch 28, this occurring just before the cam 13 begins to advance the rotator arm 24, these positions being shown in Fig. 2. When the rotator arm has swung forward its full extent the lock bolt 40 is allowed by the cam 47 to enter its next notch, and the rotator bolt 26 is withdrawn, as shown in Fig. 3, then the cam 14 and the spring 21 swing the rotator arm back.

A safet-yinterlock is provided between the rotator bolt 26 and the lock bolt 40 (Figs. 4 and 15). On the lock bolt withdrawing lever 43 is a latch 48 the free end of which'is pushed away from the lever by a spring 49 against a stop pin 48. WVhen the controller 36 is pushed over for withdrawing the rotator bolt 26 from a. notch, if the lock bolt is prevented from entering a notch 28, as for instance, by reason of the table being out of proper position. the latch 48 due to the abnormal position of the lever 43 will engage the notch 50 in the end of the controller 36 and prevent the latter from swinging outward. Under these conditions the rotator bolt is held out of action. even when the controller 36 is released by its cam 34. This prevents the injurious collision which would result from the rotator bolt engaging the table in any intermediate position of the1r turningmovements when one.

bracket 41 (Figs. 2, 6 and This lever is hell cranked and is hung so that when its handle end, which extends out toward the front of the machine, is lifted, its inner end 52 will engage and hold back the lock bolt withdrawing lever 43 and thus hold the lock bolt out of engagement and leave the table free to be rotated by hand. The handle end of this lever 51 may when lifted be sprung over a latch 53, so as to retain the lever in position to hold the lock lever back with the lock bolt withdrawn. \Vhen thelock bolt is thus withdrawn and held back, the latch 48 will interlock with the controller 36, and hold, the latter as in Figs. 4 and 15, so that the rotator bolt 26 cannot engage the table, andthe table will therefore remain stationary, while the rotator arm 24 continues its movement. The effect of this is .to prevent throwing the rotator bolt into engagement during its swing, since it can only be thrown in when the table is locked and therefore at the ends of its swing. This prevents the disastrous blow which would result from the operator attempting to start-the table rotation when the table is between stations.

The rotator bolt may also be put out of action independently of the lock bolt. Attached to the controller 36 is an arm 54 to which the rear end of a rod 55 is fastened (Figs. 2, 3, 5 and 17). The front end of this rod is connected with the upper end of an angle lever 56 that is mounted on a bracket 57 secured to the bed near the front of the machine (Figs. 10, 12, 13). The front and lower end of this angle lever is connected with a bar 58 that extends forwardly and has its front end bent to form a treadle 59, which being permanently connected with the controller 36 moves up and down as the controller swings in and out. Also by depressing this treadle as by foot pressure, the controller 36 may be moved in so as to withdraw the rotator bolt 26 from any notch in the table. On the side of the treadle bar 58 is a dog 60 and adapted to engage with that dog is a latch 61 provided with a handle 62 (Figs. 12, 14). This latch may be turned manually by its handle so as to engage the dog, and latch the treadle down (Figs. 14 and 17 which as above explained holds the rotator bolt in retracted position.

bolt 40 is withdrawn, the table rotating when the latter are exceptionally large or 7 5 mechanism is disconnected.

A brake mechanism, shown in Figs. 10 and 11'. may be employed to assist the rotator mechanism in stopping the mold tables 80 heavy, thus lessening the strain and shock upon the table rotating and locking devices. In a groove 63 around the outer edge'of each table is a brake band 64. One end of this brake band is connected with an eccentric pin 65 mounted in the swinging end of a link 66 that is pivoted on a stud seated in the support 121 (Fig. 10). The eccentric pin has a handle 68, and extending through a swivel stud 69 projecting from the link, into a fixed stud 70 is a screw threaded rod 71 with a handle 72 (Figs. 10, 11). By turning the handle 72 the link 66 may be swung to give the proper tension to the brake band. By turning the handle 68 of the cocentric pin 65 the brake may he released, as when it is desired to turn the table by hand without. disturbing the other adjustments of the brake band.

The other end of the brake band is attached to a link 73 which has a yielding connection by means of a spring 74 with a connecting rod 75 that is joined to a rocker arm 76, on the vertical shaft 77 (Figs. 10, 11). On this shaft is a cam lever 78 having a roll 79 held in engagement with a cam 80 by a spring 81. The cam 80 is adjustably connected with the rotator bolt operating cam 34 on the vertical shaft 32 (Figs. 10, '11). This cam 80 is so timed as to begin to apply the brake at about the middle of the turning movement of the table, that is, when the table has reached its highest speed, and to release the brake when the table has come to rest. The adjustable connection between the cam 80 which applies the brake and the cam 34 which controls the action of the rotator bolt permits the time of applying and releasing the brake with relation to the time pf novement of the table to be exactly reguate The cross beam 3 supports a pressing mechanism 7 for each machine, which is or may be of any well known type or construction (Fig. 1), and needs no specific description. Each of these pressing mechanisms is operated by a double-acting cylinder 83, the piston of which operates the piston rods 84, by air or other fluid under pressure, under the control of the valve and 130 interlocking mechanisms hereinafter described. Each piston rod carries the cus-' tomary forming plunger 85 and spring plate 86, to the latter of which is attached a mold 5 ring87 for closing the top of its mold 5, as shown in the right hand machine of Fig. 1, all of which is or may be of well-known construction in glass pressing machines.

The pressing mechanisms of the two machines operate alternately, each table being advanced while its pressing mechanism is in the raised position shown in the left hand machine of Fig. 1.

A valve chest 100 mounted on the bed at the front of .the machine is supplied through an inlet pipe 97 with air or other fluid under pressure. A reciprocating piston valve 113 controls the admission of the ressure, through the pipe 90 to the top of t e cylinder 83, and through the pipe 91 to the bottom ofthat cylinder, and releases the pressure therefrom through the exhaust pipes 98 (Figs. 1, 2, 6 and 19). A spring 101 (Fig. 2), mounted in the valve casing, presses the valve in one direction, and the valve is pushed in the opposite direction by one end of an angle lever 102. .This lever is pivoted on the post 44 that forms one support of the frame 94, and has a roll 103 engaging a cam 104 on the vertical cam shaft 32 (Figs.

2, 8), which operates the valve 113 that controls the movements of the piston in the cylinder 83. The cam is made in two sections, (Figs. 8, 9), adjustably connected together 35 so as to enable the time movements of that piston to be definitely regulated. When the valve is pushed in by the lever 102 air pressure is supplied to the lower part of the cylinder so as to lift the piston. When the cam permits, the spring pushes the valve out, and air pressure is admitted to the top of the cylinder so as to lower the piston and force the plunger 85 down. The valve'may be closed by hand by turning the handle 114 on the end of the vertical shaft 105 mounted in the bracket 106, so as to swing the latch 107 against the lever 102 (Figs. 2, 16 and 19). This prevents the lever from moving and holds the valve 113 closed. As previously stated, the cam 47 acting against the roll 46 on the lever 43 operates the table lock bolt, and the cam 104 acting against theroll 103 on the lever 102 actuates I the piston controlling air valve 113. The stud 108 for the roll 46 and the stud 109 for the roll 103 are extended and halved so that they can engage with each other (Figs. 8, 9). Consequently if for any reason the lock bolt is held back out of a notch these studs engage and the plunger cOIltIOlllIlg valve 113 is held so that the plunger will be held up.

The parts are thus interlocked, so that unless the lock bolt has entered a notch and locked the table in proper position the plun-y ger cannot descend. And as the lock bolt holds out the rotator bolt when the table is out of proper relation to the rotating mechanisms, the plunger will not descend until the relations are restored, so that the table will be stationed correctly for the plunger 7 to enter a mold.

Interlocking devices are also provided between the piston rods 84 and the table rotating mechanisms, so that if either plune ger should fail to rise on account of sticking in its mold, or by reason of the failure of the air pressure supply, the table rotating means will be disconnected, so that the associated table will not be moved and thus break its pressing mechanism. To accom- 0 plish this, vertical rods 110 are mounted so as to move'vertically in front of the machine. Each rod is connected by a spring 111 and the two collars 112 with an arm 124 that is attached to the piston rod 84 (Fig. 55 1) and is thus moved up and down by the piston rod. Nearits lower end each rod 110 carries two dogs 115 and 116 (Figs-13,

.14). Mounted to turn on a stud 93, fixed in a bracket 117 fastened to the post 118 is a hell crank lever 119,-carrying a latch 125 at its lower end. A spring 120 is arranged to draw the end of this lever 119 down and normally hold its latch 125 over a dog 126 attached to the front side'of the treadle bar 58 (Figs. 12, 13, 14). As the piston rod 84 moves to its upper position, the dog 115 engages a pin 122 projecting from a side of the bell crank lever 119 and lifts that end of the lever so that its latch 125 will be carried away from the dog 126 (Fig. 14) thus allowing the treadle lever to rise and the controller36 to be moved out so. that the rotator bolt may enter a notch 28 and turn the table. In the normal operation of the machine the plunger rises clear of its mold before releasing the latch 125 from th treadle 59, and thus permits the rotator bolt 26 to enter one of the notches and turn the table. If, however, the plunger should adhere to the glass, or forany reason fail to rise above the mold, the latch will not release the treadle and the controller 36, so that the latter will continue to hold the rotator bolt in its retracted position, and the table will not advance (Fig. 117). If for any reason the plunger should descend while the table is turning, as for example by the failure of the air supply,

the dog 116 will engage a. pin 123 that projects from the treadle bar and force it down and by its connecting rod 55 cause a withdrawal of the rotator ibolt from engagement with the table (Figs. 12, 13, 14).

Means are usually provided for cooling the presser plunger 85 to prevent it from being overheated by repeated contact with the hot glass. A supply of air or other cooling fluid under pressure, is conducted to the v inner plunger through the pipe 135 leading 130 from any suitable supply. Provision is made for controlling the flow of cooling fluid to the plunger in conjunction with the operation of the pressing mechanism. For this purpose the pipe 135 leads through the valve 136 (Figs. 2, 15, 16 and 19). That valve is supported by the bracket'106, with its turnin plug 137 in engagement with a slotted c0 lar 138on the lower end of the shaft 105, so that the latter opens and closes the valve when the latch 107 is open and closed. Thus the cooling fluid is supplied to the plunger 85, when the latch 'is open,

as shown in Fig. 15, to permit the normal operation of the pressing mechanism, and is shut ofl when the latch is closed (F igs.-

. The mechanism thus far described re' lates to machines for roducin glassware which is pressed, an not b own. For adaptation to a machine in which the glassware is also blown, as well as pressed, suitable blow molds and blowing heads of any ordinary and well-known construction, may be provided. The admission of the air pressure for operating the blow heads in such cases may be controlled and coiirdinated with. the mechanism above described, by means of a piston valve 128 arranged in the valve chest 100 -below the'valve 113, and similar in construction and arrangement thereto. It is positively operated in one direction against the pressure of a spring like the spring 101, by the angle lever 129 pivotally mounted on the post 44 below the angle lever 102, and provided with a cam roll 130, which is engaged by the cam 131 on the cam shaft- 32. The valve chest is connected with the blow head mechanism by pipes from the outlets 132. The operations of the blow heads are thus controlled in proper time relation to the pressing mechanism and to its controlling devices previously described.

The interlocking system above described is extended to the blow head controlling mechanism by means of the latch 133, similar to the latch 107, and similarly fastened to the shaft 105, so that the blow head op-- erating mechanism will be latched out of operation coincidently with the similar latching out of the pressing mechanism.

In the normal operation of the machine, the two mold tables are intermittently advanced by alternate movements of their advancing mechanisms shown in Figs. 2, 3 and 4, the charges of glass being fed to the molds at one station andpressed by the .the mold tables are at rest.

plunger 85 at another station, both while During this normal operation, the lock bolt releasing lever 51--52 and the

latches

61, 107 and 133 remain in their retracted positions. The latch 125 is at each downward movement of the plunger automatically moved to its latching position (Fig. 13) over the dog 126 on the treadle 59, the latter being at that time in its lowest position, to which it is moved by its connection with the controller 36 in the regular operation of the cam 34/ When the plunger rises safely the latch 125 is withdrawn, thus permitting continued movement of the controller 36, and the continued advance of the mold table.

If it is desired to stop the pressing operations without stopping the table movements,

the latches 107 133 are manually turned by means of the handle 114,,thus latching'the valves 113 and 1.28 in their closed position, and also shutting off the flow of cooling fluid to the plunger, by the valve 136.

When it is desired to stop the advancing movement of the table, the latch 61 is manually turned to its latching position shown in Fig. 14 by means of the-handle 62. This leaves the'locking bolt. mechanism free to lock the table at any of its stopping stations. tire machine, including the table locking mechanism, the lever 5l52 is manually turned to the position shown in Figs. 4, 6 and 15, which by means of the latch 48 holds the controller 36 out of operation and by means of the interlocking heads of the studs 108 and 109 (Figs. 9 and 18) also holds the plunger controlling valve 113 closed. Throughout any of these uses of the interlocking stops of one mold table, its companion mold table maycontinue its normal operation and production.

The mold supporting table 4 which is herein shown as a flat topped circular bed or table, may be of any of the various forms well known in this art, sometimes consist ing of arms, or otherwise more or less skeleton in form. Functionally, it is a mold support; but is herein described as a table, for the sake of brevity.

Various well-known constructions and ar-- rangements of the piston valves, their ports and passages, and the pipes for admitting air from the source-of supply to the valve When'it is desired to stop the en chest, and for conducting the air from the valves to the cylinder and to the blow heads, may be employed, such details being adapted to various requirements by the expected skill of designers and mechanics familiar with this art. In like manner the various constructions and arrangements here shown may be inverted or transposed and otherwise modified and adapted to suit various conditions and requirements of service.
