Abstract:
A drive system for arcuately oscillating the gob guiding units (11a, 11b) of the delivery system (10) of a rotating table type glassware forming machine. The drive means includes a drive shaft (302) having a crank (304) and associated crank roller (306) at oneend, the roller being operatively situated within a crank box (308) on one of the gob guiding units. Rotating of the drive shaft causes oscillatory motion of the gob guiding unit. A connecting link (310) is provided to transfer this motion to other gob guidingunits.
Abstract:
A control system (10) for the control of a multisection glassware forming machine (14) in a manner which enables totally independent operation of any section regardless of the status of remaining sections. The control program for each section is stored in unalterable, read-only memory within a local computer (12a-12n) associated respectively with each section. Each local computer is provided with at least two communication ports (61, 62). A local terminal (60) may be selectively connected to any local computer via one of the communication ports to enter and display timing setting data. A machine terminal (64) or machine supervisory computer (90) may be selectively connected to any local computer through the other one of the ports. A bidirectional communications interface enables data transfer between the selected local computers and selected data input/output devices.
Abstract:
A forehearth for a glass furnace includes a roof formed of a plurality of roof blocks (22) designed to provide below the roof blocks a central longitudinal channel (36) and side channels (38, 40) on each side of the central channel. An electric heating element (60) is positioned in a bore (62) in the roof blocks substantially directly above the side channels (38, 40) to permit radiation of heat to the glass surface above the side channels (38, 40). The temperature of the molten glass utilizing the construction can be effectively uniformly controlled across its cross-section.
Abstract:
A glassware forming apparatus including at least a pair of split blow molds (14, 16). Means (28) is provided for cooling each mold segment during the period the molds are open. Means (30) is provided for stopping the flow of cooling fluid when the molds are closed.
Abstract:
A four axis adjustment mechanism (100) for adjusting the orientation of the deflectors (104) of the delivery means of a rotating table type of glassware forming machine. The orientation of each deflector is adjustable as it oscillates along a predetermined arcuate path relative to its deflector axis (443) in order to properly position the deflector over a corresponding continuously moving blank mold. These adjustments are termed radial, radial tilt, peripheral and peripheral tilt.
Abstract:
A takeout tong head includes a support bracket (2) having an upper portion (4) adapted to be attached to a takeout arm and a lower portion (6) having at least one cylinder housing (8). A cylinder and tong assembly (16) is associated with each cylinder housing (8) and includes a mounting flange (18) removably attached to the cylinder housing (8), a cylinder (20) extending into said cylinder housing (8), a piston member (26) in said cylinder (20), a scissors tong assembly (34) extending downwardly from said flange (18), and a piston rod (28) extending from the piston (26) to the scissors tong assembly (34).
Abstract:
A lockset assembly which includes a bolt (12) movable between a partially extended latching position and a fully extended dead bolt position. When the bolt (12) is in the dead bolt position, the inside lever (10) can be used to retract the bolt. The outside operating assembly (27) is provided with a key operated lock cylinder (22) and the inside operating assembly (44) is provided with a turn button (26).
Abstract:
A conveyor cam adjusting apparatus permitting adjustment of the radial position of each cam (30) on a drive shaft (32) while it is rotating. A plurality of individual electric motors (44) are mounted for rotation about a common drive shaft each motor being associated with a single cam. Each motor is provided with a means (140, 142) for manually selectively connecting it to a control means (144, 150) in order to enable an operator to rotate the associated cam relative to the common drive shaft while the shaft is rotating. A sensing means (150) may be used to detect the position of each cam relative to a predetermined reference position and the output of the sensing means may be used by a computer control means to automatically selectively activate each motor to adjust the associated cam accordingly.
Abstract:
An adjusting mechanism (100) for the press head (103) of a glassware forming machine of the rotating table type having a plurality of forming units circumferentially spaced for rotation about the axis of the machine. Each forming unit is capable of producing at least two glassware articles per machine cycle. A remote ram spring adjustment means (150) provides operator control of ram spring pressure for each plunger at an accessable height and location.
Abstract:
A forehearth for the conveyance of molten glass has at least one cooling zone which includes a trough (2) and a roof (17) over the trough. A pair of spaced projections (28, 30) extend downwardly from the roof to define in the space below the roof a central channel (36) over the central portion of the stream of molten glass and side channels (38, 40) over respective side portions of the stream of glass. The roof has at least one area (44) of reduced thickness in the portion over the central channel. An enclosed upper cooling channel (54) extends longitudinally of the forehearth over the area of reduced thickness and has an inlet (56) and an outlet (58) spaced longitudinally from the inlet. Heating means (20) are provided for applying heat to each side portion of the stream of glass.
