GLASSWORKING MACHINERY.
Application filed February 26, 192 7 Serial No. 171,173.
The present invention relates to machinery for'working hollow parts for shaping them into desired forms.
Various objects and advantages of the in- 6 vention will be obvious from the following particular description of one form of apparatus embodying the invention or from an inspection of the accompanying drawings; and the invention also consists in cer-.
tain new and useful features of construction and combinations of parts hereinafter set forth and claimed.
In the accompanying drawings there is shown for purposes of illustration one form of apparatus embodying the invention, in
which Fig. 1 is a front elevation view of a ma- 5 chine embodying the invention.
Fig. 2 is a side elevation View thereof, Fig. 3 is a diagrammatic View showing details of the machine in side elevation,
Figs. 4 and 5 are respectively front and side elevation views of other details, and
Fig. 6 is a longitudinal view illustrating a glass tube having annular enlargements formed thereon by the machine herein illustrated and described.
In the drawings the bed plate 10 supports at each end a pairof standards 12 and 14. Said standards 12 support between them the shaft 16 which is movable rotationally therein. Said standards 14, 14 support between them the fixed shaft 18. Near one end of said plate 10 the posts 20, 20 and 22, suport the block 24 having the longitudinal Eosses 26 and 28 through which said shafts 16 and 18 extend respectively. At the opposite end of the machine said shafts 16 and 18 carry the block 30 which has a pair of bosses 32 and 34 through which said shafts 16 and 18 respectively extend and by means of which said block 30 is slidable longitudinally on said shafts 16 and 18. On a line extending vertically between said shafts 16 and 18 said block 24 carries a train of gears 36, 38 and 40. In similar arrangement said block 30 supports a vertical train of gears 42, 41 and 46. Said gears 6 and 42 are connected by a telescoping sha t comprising the shaft 6 48 connected to said gear 36 and a hollow shaft 50 connected to said gear 42, said shafts 48 and 50 being splined together to provide proper driving connection therebetween and to permit a longitudinal movement of one with respect to the other. ,A longitudinal rack 52 connected to said block 30 and .a pinion 54 mounted to said plate 10 and having a hand wheel 56 serve for moving said block 30 longitudinally on said shafts 16 and 18. The said shaft 48 carries a driving pulley 60 and clutch member, the details of which are not shown, said pulley 60 being driven by the belt 64 which is connected to the driving motor 66. Said pulley 60 is engaged and disengaged from said shaft 48 by means of the foot treadle 68 which is bonnected to said clutch member not shown. Said gears 40 and 46 carry respectively the chucks 70 and 72 which are axially allgned and extend toward each other. Said chucks 70 and 72 are of the spring expansible type in which a set of jaws is acted upon by a spring to tend to move them apart and a sleeve is slidable over tapering surfaces on said jaws to draw them together into the clamping position. Each of said chucks 70 and 72 has a bell crank 74 and 76, respectively, which are pivotally mounted to said blocks 24 and 30 respectively and are connected to the sleeve of the respective chuck .for moving it into the clamp closing position, slidable and pivoted connection therebetween being made respectively through slots 78 and 80' respectively, in said blocks 24 and 30. Said shaft 16 carries a crank lever 82 which connects through the chain 84 to said bell crank 74 and at said block 30 said shaft 16 carries the crank lever 86 which connects through the chain 88 to said bell crank 76. Said foot pedal 68 is connected through said rod 64 and lever 82 to said shaft 16 and serves to actuate it to operate said chucks 70 and 72, said lever 82 being fixed to said shaft 16 and said lever 86 having a sliding connection therewith through a spline on said lever 86 and the longitudinal keyway- 92 formed in said shaft 16.
Below said chucks 70 and 72 a carriage 94 rides on said shafts 16 and 18 through rollers 96 and 98, and guide rollers 100 and 102 guide said carriage 94 against lateral movement on said shafts 16 and 18. Said carriage 94 supports a mold member 104 which is pivoted thereto at the standard 106 for movement into operating relation with a piece of glass tubing carried by and extendmg. between said clamps 70 and 72, such movement being imparted to said member 104 through the lever 108 fixed thereto, the connecting arm 110 pivoted to arm 108 at one end and pivoted at its other end to a bell crank 112, and from there through the connecting rod 114 the lever 116 and the connecting rod 118 to a foot treadle 120. A stop 122 mounted on carriage 94 below said member 104 serves to limit its movement downward and the screw 124 adjustable in an arm 126 extending backwardly from and fixed to said member 104 serves by engagement with a part of said carriage 94 to adjustably limit the upward movement of said mold member 104. Longitudinal movement of said carriage 94along said shafts 16 and 18 is imparted by means of the sprocket chain 128 which passes over a sprocket 130 which idles on the shaft of said sprocket 54 at one end and over the sprocket 132 mounted near said block 24, a hand wheel 134- being provided for said sprocket 132 for the actuation of said chain 128 and thereby said carriage 94 in either direction, said connecting rod 114 being of suitable length and flexibility of connection with the levers at either end thereof to permit such longitudinal movement of said carriage 94. One on either side of said carriage 94 and directed inwardly toward the line between said chucks and 72 are mounted the sets of gas jets 136 and 140 connection thereto being made through the flexible hoses 142 and 143 to a valve 144 to a suitable source not shown, a foot treadle 145 being provided for the operation of said valve 144, a semiautomatic stop or position indicating arrangement for said carriage 94 comprises a longitudinal bar 146 mounted at the rear of the machine and having therein a number of V notches 148 facing forwardly. A block 150 carried by the block of said jets 140 slidablysupports a dog 152 which is held 1n engagement with said bar 146 by means of the spring 154, said dog 152 having inclined surfaces which upon engagement with the surfaces of said V notches 148 will cause the movement of said dog 152 against compression of said spring 154 to permit the longitudinal movement of said carriage 94 longitudinally in either direction.
Said chuck 72 has a stopper member 155 therein for closing up the open end of a glass tube or other hollow glassware held thereby and said chuck 70 has a stopper 156 therein which has a central opening therein for supplying air pressure to a piece of hollow glassware held by said chuck 70, connection from a suitable source not shown being made through the tube 157 and the passage 168 formed through said post 22, block' 24 and the mandrel or shaft of said gear 40 and chuck 70. A by-pass 159 connecting with said channel 158 is provided near hand wheel 134 to regulate the pressure at which air is supplied to a tube. held by said chuck 70.
In the use and operation of the above described machine embodying the invention for forming, for example, annular enlargements from glass tubing such. as are illustrated in,
F igs. 1 and 6 a glasstube 160 is mounted said chuck 70 and 72, said pedal 68 being depressed for this purpose to stop the rotation of said chucks and to open them and then being released to permit them to close and again put them into rotation. Said tube then being preheated at each end by fires from said jets 140 to prevent uneven expansion thereof and consequent cracking, said carriage 94 by means of said hand wheel 134 is moved to either extreme position at the.
right or at the left to have said dog 152 engage one of the end ones of said notches 148. Through said foot pedal 145 the gas of said torches 140 is raised to heat'said glass tube to the softened point whereby the thickness of the wall thereat is maintained by the same thickness as that of the tube proper or at any other desired thickness. The synchronous rotation of said chucks 70 and 72 and the rotation of the softened glass against said mold 104 provides for the forming of a symmetrical enlargement of the glass at the worked portion. One enlargement having been formed said carriage 94 by means of said hand Wheel 134 is moved toward the opposite end of said tube 160 and stopped at the next V notch 148 where the enlargement forming portion is repeated. The formed glass at a previous enlargement cools and hardens sufliciently by the time glass is softened at the next subsequent Work place to permit working without changing the shape of said previously worked part. In this manner a succession of enlargements are formed on said glass tube 160 one after another. a
It is to be understood that the worked glass can be shaped into various forms suitable molds being provided for that purpose and that the form illustrated in mold 104 can be varied from without departing from the spirit of the invention.
While we have shown and described and have pointed out'in the annexed claims certain novel features of the invention, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its use and operation may be made by those skilled in the art without departing from the spirit of the invention.
We claim 1. In machinery for working hollow glassware, a set of gas jets projecting toward and movable along a given line, a pair of work holders for supporting a piece of hollow glassware along said line, one of said work holders being movable toward and from the other, a mold movable into operative relation to apiece of work held by'said work holders and mounted to move with said jets for movement therewith along said line and a positioning means comprising a latch member having a plurality of latching parts arranged along said line and a cooperating latch member carried by said mold and movable along first said latch member into and out of operative relation to said latching parts.
2. In machinery for working hollow lassware, a set of gas jets projecting towar and movable along a given line, a pair of work holders for supporting a piece of hollow glassware along said line, one of said work holders being movable toward and from the other, a mold movable into operative relation to a piece of work held by said work holders and mounted to said fires for movement therewith along said line and a positioning means comprising a latch member having a plurality of latching parts arranged along said line and a cooperating latch member carried by said mold and movable along first said latch member into and out of operative relation to said latching parts and means for applying air pressure to the interior of a hollow glass blank held by said work holders.
