The invention relates generally to improvements in that type of feeder in which the glass is fed in shaped suspended mold charges, by means of an implement reciprocatin in vertical alignment with the flow orifice oi the how spout. One of the objects of the invention is to generally improve the construction of this type of feeder, whereby the some may be more easily adjusted, and will at all times be under the control of the operator in a most convenient manner.
Another object of the invention is to provide an operating mechanism which will e1 fect a great saving oi compressed air or other operating fluid, in that the amount of operating fluid required will be substantially reduced as the length of stroke is reduced.
Further objects and advantages oi the invention will be apparent to those skilled in the art, from the following detailed description taken in connection with the accompanying drawinps; in which:
Figure 1 1s a side elevation of the complete apparatus; the usual flow spout being shown in dotted outline.
Figure 2 is a plan view or the apparatus.

Figure 3c is a detail horizontal sectional view taken on line 3a--3a of Figure 1.
Figure 4 is a vertical sectional view of the feed plunger operating cylinder, and showing the adjusting means associated therewith.
Figure 5 is a vertical sectional view of the vertically adjustable bracket, and asso-' ciated parts; and i Figure 6 is a bottom plan view of said bracket. c,
Referring to the drawings more in detail, numeral 1 indicates indotted outline a conventional flow spout provided with the usual flow orifice 2. rranged below the flow ori-, fice are the usual shears (not shown) for severing the shaped suspended gobs to be fed to a forming machine.
Mounted for reciprocation in the flow spout, in vertical alignment with the flow orilice, is the ordinary feeder plug 3. This reciprocable plug is attached to an operating rod 4: in any desired manner, but the particular means I have employed in practice and illustrated herein, consists of the following:
An angular member 5 is removsbly attached to the lower end of the rod d and partagainst the feeder plug. 3, thereby holding the reciprocating parts in vertical alignment with the flow orifice.
The operating rod 4 is slidably mounted in bearings 11, 11,011 abracket 12. A crosshead 13 is adjustably secured adjacent the upper end of operating rode by means of a, set screw '14:; and pivotally attached to the crossliead are links 15., 15, which links ore pivotally attached .at their lower ends to the walking- beams 16, 16. These walking-beams are pivotally mounted at 17 on a slide bracket 18, to which the bracket 12 is rigidly attached; and the ends of the walking-beams remote from the feeder are pivotally attached by means of a pin 19 to a link 20; the latter being pivotally attached at its lower end to a fork 22 by means ofa pin 21.
fork is screw-threadedly secured to the coland therefore before describing this mechanism I shall describe the structure my which the feeder plug may be adjusted in various directions with respect to the flow orifice.
In addition to the means for adjusting the limits of the feeder stroke, to be described hereinafter, this device includes mechanism for effecting three separate and distinct ad- 'justments of the feeder plug with respect to theflow orifice, as follows:
First, means for bodily raising or lowering the feeder plug with respect to the flow orifice; that is, means for simultaneously raising or lowering both limits of the feeder stroke without changing the length of the stroke.
Second, means for moving the plug laterally with respect to the flow orifice.
Third, means for circumferenti ally adjusting the plug about the main supporting shaft as an axis.
These various adjusting means will now be described in the order named.
In the specific structure illustrated herein, a bracket 28 is attached to the flow spout casing, and this bracket is provided with bearings 29, 30, in which a shaft 31 is rotatably mounted. To-permit rotation of the shaft 31, and at the same time prevent vertical translation thereof, collars 32 and 33 are attached tothe shaft, respectively above and below the bearing 30, and arranged between the upper collar 32 and the bearing 30, is a ball-bearing race 34.
Attached to the lower end of the shaft 31 is a bevel gear 35, which may be operated b a handle 36. However, it is sorn s desira le to make the adj ustment f "M11 and accordingly I meshing with the bevel on a shaft 38 whi 1 enter: venient for operation.
Referring now particularly to Figures 5 and 6, it will be seen that the shaft 31 extends upwardly through a sleeve 39 the upper end of the shaft bein reduced in diameter and screw-threaded. nut 40 is screwed down on the reduced portion of the shaft 31, into position in the sleeve 39, and is locked in lace in the sleeve by means of a screw 41. t is thus apparent that the sleeve 39 is supported by or suspended from the upper end of the shaft 31, and that by rotation of the y point conparent that when the a shaft the sleeve will be raised or lowered, depending upon the direction of rotation;
The lower end of the sleeve 39 is cast integral with, or attached to, a supporting plate 42; the specific structure of the plate being shown by the bottom Figure 6. v
The slide bracket 18, carrying the feeder plug and associated operating parts, including cylinder 24, is mounted on the supporting plate 42.-
It is thus apparent that by the rotation of the shaft 31, the feeder plug and its entire operating mechanism may be raised or lowered to the desired extent, thereby varying the vertical position of the plug with respect to the flow orifice, at both the upper and lower limits of the plug stroke, but in no way varying the length of the plug stroke.
The means for adjusting the plug laterally with res ect to the flow orifice, will now be described The supporting plate 42 is, of course, fixed against lateral sliding movement, as the sleeve 39 which is integral with the supporting plate, embraces the shaft 31. However, the bracket 18, which carries the feeder plug, its operating parts, and its operating cylinder, is laterally slidable on the plate 42. The bracket is secured to the supporting plate by means of bolts 43 which pass through openings 44 in the supporting plate; and to permit lateral sliding adjustment of the bracketthese openings 44. are elongated, as clearly shown in Figure 6. Also to provide clearance for the cylinder 24, which is bolted to the sliding bracket 18, the supporting plate is rovided with an elongated opening 45.
epending from the supporting plate 42 is a lug 46, and threaded therein is a screw 47. The screw has a reduced portion 48 which is located in an aperture in plate 49 rigidly attached to the cylinder 24. The hand wheel 50 is mounted on the outer end of the screw, and the hub 52 of the hand I ongitudinal movement with respect to the plate.
From the above description it will be apjusting member 50 is rotated the late 49 will be moved to the right or left Fig. 1). The plate 49 is attached to the cylinder 24, the cylinder is attached to the bracket 18, and the bracket 18 carries the reciprocable feeder plug and its associated operating parts, so that when the plate 49 is moved, the feeder plug, the brack et, the operating cylinder and all connect ing elements will be moved bodily to the same extent, thereby laterally adjusting the feeder plug with respect to the flow orifice. The means by which the feeder plug may be circumferentially adjusted about the supporting shaft 31, will now be described.
plan view thereof, in
A plate 53 is pivotall mounted on the shaft 31 and is supporte on the upper surface of the hearing or bracket 29. An extension 54 is attached to the bracket 29, and a screw 55 ,is mounted in this extension against longitudinal movement, as clearly shown in Figures 3 and 3a; the screw being operatedby the hand wheel 56.
1%. lug 57 is integral with or attached to the underside of the plate 53, and is tapped to receive the adjusting screw 55. Lug 57 has a depending stud 57, passing through aslot 54 in extension 54, and furnished with a nut The plate 53 is provided with a wide'slot.
58 to receive the lower stufing box of the cylinder 24, and the walls of this slot closely fit the depending plate 49 carried by the cylinder. So that, as the plate 53 is moved about itspivot (shaft 31), it will carry with it the cylinder 24, bracket 18 and feeder plug 8, thereby adjusting the plug either toward the frontor rear of he iiow s out, as may be necessary to properly align t -e plug with the flow orifice.
Thus it the feeder plug has ecome deformed, or in any manner has been thrown out of alignment with the orifice, it may, by the rotation of the hand. wheel 56 or the wheel 56, be moved laterally to bringit into true alignment with the orilice. Or if glass being oi different temperatures on difierent sides oi the orifice causes the gobs to incline to one side-as they leave orifice, they oan be made to assume a vertical position by changing the relation of the point of the plug to the orifice, by the various adjusting means described above.
Theparticular means employed for simultaneously adjusting the upper and lower limits of the feeder plug stroke, and by which means a considerablev saving of compressed air or other operating fluid is eiiected,will now be described.
Referring particularly to Figure 4, it will be noted that the piston rod23, within the cylinder 24, is provided with right and left handed threads and that mounted thereon are two pistons 59 and 60. Ports 6i and 62 deliver the operating air above and below the piston heads 59 and 66 respectively; To provide against the turning of the pistons a rod 633s passed through holes therein, and the rod is floatabiy secured in place by inserting the ends thereof in recesses provided in the cylinder heads 64 and 65. I
Mounted onthe lower end of the piston-rod is a notched wheel 66, by means of which the piston rod may be rotated to adjust the pistons. It is ap arent, of course, that after the pistons have can adjusted, the piston rod must be held against further rotation until another adjustment is desirable. For this purpose I provide a vertical bar 67.which is carriedxby rods 68, positioned in key hole slots 69 in the plate 49, the slots being shown generally by dotted lines in Figure 1. With these parts in the position shown in Figure 1, it is apparent that the rod engages one of the notches in wheel 66, thereby preventing rotation thereof, yet at the same time per- .mitting the piston rod to be reciprocated.
Now if it is desired to rotate the notched hand wheel to adjust the pistons, it is only necessary to lift the rods 68 by the handle 70, until the round rods are brought into alignment with the round part of thekey hole slots, and
then retract the members suificiently to disengage the vertical bar 67 from a notch in the hand wheel 66, whereupon the wheel may be turned to move the pistons to the. desired position. After proper adjustment the bar 67 will be moved into engagement with one of the notches, and the locking mechanism will be lowered by the handle 70 to bring the flattened portions of the rods 68 into the narrow portions of the key hole slots, thereby securing the locking means against accidental displacement. Counterweights 71 are employed to squat" ize the pressure required to raise lower the piston rod. The operation of the adjusting means within the cylinder % 4 will be understood from the foregoing description. the piston rod 23 is turned in one direction the pistons 59 and rection the pistons will be simultaneously moved away from each other, thereby simultaneously lowering the upper limit of stroke and raising the lower limit of stroke.
urther, the adjusting means described above efiects a very material saving of oper ating fluid. it will be apparent from an inspection oiiFig-ure 4 that the operating fluid is supplied only to those portions of the cylinder above the piston 59 and below the piston 60; the portion of the cylinder between the piston being a dead air space. When the pistons are moved toward each other the slicetive length of the cylinder is increased, and when they are moved away irom'e'ach other the eiiective length of the cylinder is decreased. The amount of compressed air emother operating fluid required, is also reduced.
The operations of the several adjustments have been described hereinbefore, and there is no necessity for further description of the operation. By rotation of the hand wheel the feeder plug is moved toward the right or lift (Figure l) to bring it into true alignment with the flow orifice. By rotation of the hand wheel 56 the feeder plug is moved toward the front or rear (Figure 1) to bring it into true alignmentwith the flow orifice. By rotation of the shaft 31 the limits of the feeder plug stroke are simultaneously varied in the same direction, either upwardly or downwardly, whereby the length of stroke remains the same but the vertical position of the path of stroke with respect to the flow orifice, is changed. By rotation of the piston rod 23 the limits of the feeder plug stroke are simultaneously varied in opposite directions, thereby varying the length of the stroke as well as varying the limits thereof.
Obviously, the invention disclosed herein is subject to numerous changes modifications, and it is my intention to include all such changes and modifications within the scope of the appended claims.
