The invention relates to glass-working apparatus and it has'particular relation to tunnels for delivering mold charges of molten glass to molds for shaping hollow glass` ware of rectangular cross section.

In shaping parisons for battery jars "and other hollow glass articles having inclined sides and of rectangular cross section, and particularly Where the charge is introduced l0 into an inverted mold through the smaller bottom end of the mold, diculty is encountered'in obtaining the proper distribution of glam in the mold. This diiiculty is occa'- 'sioned by the necessity of feeding relatively 16 -long and narrow mold charges to the mold through the comparatively restricted opening in the bottom thereo, and the consequent tendency for a charge of such shape to tilt or slump laterally in the mold after it is delivered thereto, with the result that the glass either fails to Sill the corners of the mold or more glass ilows to one side than to another when the shaping pressure is applied.

One of the objects of the present invention is to minimize the' aboveLmentioned diiiicultics by providing a funnel adapted to be inserted into the mold to a point adjacent to the bottom thereof, so as to provide lateral support for the upper portion of the charge until the lower portion has settled evenly in all directions sur'iiciently to prevent lateral slumping after the funnel' is removed.

Another object is to provide a unnel of ,rectangular cross section adapted `to be ernployed with a mold of similar cross secltional sha e, so as to impart a, preliminary conguration to the charge corresponding to that of the mold.

A still further object of the invention is to provide a funnel which may be adjusted vertically according to the size of the mold and the size'of the mold charges being delivered to the mold.

In the accompanying drawings:

Figure 1 is a plan view of a. funnel and adjusting mechanism constructed in accord ance with the invention;

Fig; 2 is a side elevational view of the structure shown in Fig. l, the mold being illustrated in vertical' section; and

, lower vinder 28Athiou'gh a pipe. 30 (Fig. l) which, acting upon the piston 31, forcesthe same Fig. 3 is a sectional plan view of the mold with the funnelin place therein, shown on line 3-3 of Fig. 2. Referring to the drawings:

An inverted blank mold 1, suitable7 for 5 making battery-jar parisons, yis shown l a'be ing mounted upon a suitable su port or table 2 and is provided with a nec ring 3 `and with .a neck plunger 4. This mold is rectangular in cross section and 4its 'sides converge toward the bottom where an opening 5 is provided through which the mold charges are introduced. i

A funnel 6( of rectangular cross section and Ahaving an upper flared portion 7 and a portion .8 having substantially parallel sides, 1s mounted lfor vertical movement in axial alignment-,with the mold 1. This funnel is mounted in Aa ring 9 which-is provided with a vertical arm .10 havinfy a groove 11 formed therein and provided with gibs 12 for sliding engagement with'a vertical track 13. The track 13 is carried by an arm 14 that is secured to a bracket 15 which is supported in any convenient manner, but which is referably mounted upon a portion of the s aping machine, not shown.

The funnel v6 is withdrawn from the mold,

after the .mold charge is fed-,bv a lever 16 L.

which is keyed to a shaft 17 ournaled yin bearings 18 and 19 which are respectively provided on the arm 14 and on a' bracket 20 carried thereby. The forward end of the lever 16 projects through a slot 21 formed in the track 13 and is connected to the arin 10 by a link 22. l I

Alever 23 is also keved to the shaft 17 and is provided with a lug 24 which is adapted to' f' be engaged by a lug 25,-pr0vided'on :Liever 26 -which is freely mounted on the shaft 17. 9 The lever 26 is onnected to the pistonv rod 27 of a fluid pressure cylinder 28 which is piv- .tally mounted, as at 29, upon the bracket 20. y

i In order to raise the funnel 6 from the" mold, luid pressure is admitted into the cyL t0 the left and'swings the lever 26 in a counter-clockwise direction. This 4movelBBifQ the hiver 26 moves the 1uz25 carried 109 yon the/lever sooner or leter in order to no thereby into abutting engagement with 'the lug 24 on the lever 23 and swings this lever, together with thev shaft/17, in the seme dire@ tion. The movement thus imparted to the shaft 17 swings the lever 16 upwardly and clevates the funnel @from the mold.

When it is desired to lower tlie funnel .into the mold,v the luiol pressure in the right hand end of the cylinder 28 is allowed to escape through the pipe 30 and ressure 1s ad mitted through e pipe 32, there v forcing the piston 31 and lever 26 to the right, as viewed in Fig. 2, and allowing the funnel 6 to descend under the action of gravity.

,in order toregulete the distance thet the funnel is lowered into-the mold1 to suit the size of the mold and the size of themt'ltd: charges being delivered thereto, the toll vv ing mechanism is provided. A lever 33 is keyed to the shaft 17 end is provided with e lug 34 which is adopted to engage e lop; 35, provided on o hand iever 36. This lever is freely mounted on the shaft ll and is provided 'with spring detent 37 'for enga-gement l with en monete rook 3%3 which is fixed to 'the arm 14. By oic'liustint: lthe position of the hond lever opt-he pos tion or" tliefliig 35 will ybe shifted soles to be engaged ov the hij' 36's speetivelv/ "decrease orsincreese the depth Ito l which the funnel is allowed to' deseendl For exampleyif the hand lever 36 ifa/swung to o. position above that shown in'Fig. i2, the iup; 35 carried thereby will be engaged eeriier by the lug 34 on the lever 33 with the, result that the motion of 'the shaft l? and the lever'lt will be stopped and the descent o 'the Juni'iel (i will be arrested at e higher level. En snob event, the movement of the lever will also bexstopped, lout that of the lever carrying the stop 25 will continue until the piston-,A
