ALBERT N. CRAMER, OF TOLEDO, OHIO, ASElIGNOR TO THE OiVEI-TS BOTTLE COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

GLASS-FEEDING APPARATUS.

Application filed September 25, 1926.

The present invention relates to improvements in glass feeders, and particularly to means for steadying and guiding mold charges during their formation and after theirseverancc from the main body of glass. It is customary to mount charge guiding means directl upon the shearing mechanisn but with such an arrangement it has been found that the charges are displaced laterally or tilted so that they are not properly delivered into the molds. The above condition is due to the fact that the guiding means being attached to one of the shear arms, moves laterally during the formation of and after severance of a charge.

An object of the present invention is to provide a mold charge guide adapted for nmlti-directional adjustment and mounted independently of the'shear mechanism and adapted to remain stationary in a position adjacent to the mold charges being formed and severed for minimizing lateral movement of the mold charges under influence of action of the shear mechanism.

Another object is to provide charge guid- 'ing means adjustable horizontally toward and away from and longitudinally of the feeding axis of the feeding mechanism.

A further object is to provide a charge guiding and steadying device mounted independently of the shear mechanism and ca pable of nmlti-directional adjustment during operation of the feeding mechanism and other apparatus associated therewith.

Other objects will be apparent hereinafter.

In the accompanying drawings:

Fig. 1 is a fragmentary front elevation of a glass feeder mounting my improved charge guiding means. I

Fig. 2 is a top plan view of the charge guiding means, the glass feeder and cutters being shown in dash and dot lines.

Fig. 3 is a detail perspective View of the adjustable deflector arm.

Fig. l is a section taken on the line IVIV of Fig. 2.

In the accompanying drawings, the charge guiding means is illustrated in connection with a feeder boot adapted to contain molten glass from which mold charges are formed, such charges being periodically severed from a stream issuing through the lmttom outlet opening 9 by shear mechanism including a pair of opposed cutters 11 mount- Serial No. 137,774.

ed upon arms 12 below the boot or forehearth. T 1e charges are delivered to molds M through. their open upper ends. A plunger 8 regulates the issue of the glass.

A hanger or bracket 13 is formed with a vertical attaching arm ll through which bolts or the like fasteners 15 are passed for rigidly attaching the hanger to one side wall of the feeder boot 10 (see Figs. 1 and A horizontal extension 16 arranged at right angles to the arm 14 is formed. with a vertical bolt opening near its outer end. This hanger 13 is provided at the side opposite the entension 16 with relatively right angularly disposed bearings 1? having threaded openings adapted to receive adjusting screws 18. These adjusting screws are controlled by hand wheels 19 and cooperate with associated mechanism to change the location of charge guiding means carried by an arm 21, as will be hereinafter brought out. The adjustments may be made while the feeder is in operation. The inner adjacent ends of the two adjusting screws 18 abut right angularly disposed vertical sides of the head 20 formed on one end of-the charge guide carrying arm 21, which is fulcrumed to the outer end of the aforementioned. extension or arm 16 of the hanger 13. Such attachment of the charge guide carrying arm to the extension 16 is effected by means of a pivot bolt 22 extending through a vertical longitudinal slot 23 in said arm and through the bolt hole in the extension 16. This connection provides for both pivotal and sliding movement of the charge guide carrying arm with respect to the hanger 13. The arm 21 is formed with a depending re-enforcing web 24, one end of which terminates below the head-20 and is formed with. an eye 25 to which one end of a coil spring 26 is attached. The other end of the coil spring is fixed to a tensioning device, including a screw 27, extending through a bearing 28 and adapted to be ad justed longitudinally therein by means of a nut 29.: This bearing 28 is located between the adjusting screws 18 and is integrally cast with a depending flange 4-5 on an extension 30. The hanger, including the attaching arm 14, extensions 16 and 80, and the several bearings is preferably formed in a single casting and. includes suitable reenforcing ribs (see Figs. 1 and 2.)

The coil spring 26 yieldably holds the head 20 of the charge guide carrying arm 21 in paratus.

engagement with the inner ends of the adjusting screws 18 so that with manipulation of either screw, the relation between said arm and the hanger will be changed and in turn shift the charge guiding means relative to the feeding axis of the feeding mechanism.

The forward or inner end of the charge guide carrying arm 2i is provided with a lateral extension 31. The front edge of the lateral extension 31 is provided with a depending flange 32 substantially V-shaped in horizontal cross section. Adjacent the lower edge of this vertical flange 32 is formed a longitudinally rearwardly extending arm 33 below a portion of the extension 31. Vertically aligned openings 34 are formed in the extension 31 and arm 33 to receive a threaded bolt 35 whose upper end is attached to a charge guide or steadying device 36. This charge guide 36 includes a horizontal portion adapted to overlie the extension 31, the forward end of the guide including a depending flange 37 whose shape conforms to that of the aforementioned flange 32 at the forward end of the charge guide carrying arm 21. Opposed guiding ribs 38 are formed upon the charge guide 36 and are slidable in vertical ways 39 (see Figs. 3 and 4;). A regulating wheel &0 is arranged between the extension 31 and the arm 33 and is threaded upon the bolt 35 for varying the elevation of the charge guide 36 as may be required when the shearing mechanism is adjusted relative to the feeding mechanism.

By adjusting the screw 18 which abuts the outer end of the head 20, the charge guide carrying arm 21 will be moved longitudinal- 1y, such movement being permitted due to the bolt and slot connection between said arm and the extension 16 of thehanger 13. The other adjusting screw being stationary, coacts with the spring 26 in preventing lateral movement of the arm. Thus, it is seen that this longitudinal adjustment may be effected 'entirelyindependent of any other adjustment.

In the same manner, the other adjustingscrew 18 may be operated to move the charge guide carrying arm around its pivot, and during this adjustment the first screw and the coil spring 26 coact with each other to prevent longitudinal movement of said arm. 'By alternately operating these two screws, the charge guide may be accurately adjusted during operation of the feeding mechanism and associated ap- In the event the elevation of the shears is changed, or if for other reasons, raising or lowering of the charge guide 36 is required, such adjustment can be effected by operation of the hand wheel 40.

Manifestly, certain changes may be resorted to within the spirit and scope of the appended. claims.
