2-Claims. (01. 49-63) This invention relates to the grouping coherence of fines as a mass and constituents for a melt.

This invention has utility when incorporated as a pre-formed supply more or less vitreous mass for glass furnace or cupola' furnace to be the ingredients as combined for the melt.

Referring to the drawings:

Fig. 9 is a detail view oithe plunger element in which the number of parts is reduced.

Dry mixer I groups the elements of sand, lime, lead, soda ash, cullet, and other fines for melted glass, which may be brought by elevating conveyor 2 and dumped into mixer 3 (Fig. 1). In this mix may be established a suppression of the dust through the medium of a binding element, whether such be water glass, or in the instance of milk of lime, lime water, or hydrated lime, if

such be in liquid form. This added moisture from supply duct 4 may be controlled by valve 5 and discharge of the mixer 3 driven from the shaft B-by belt I.

From this mixer 3 there may be delivery spout 5 8 to pan 9 operated by vibrator l0. There is thus efiected shaking uniformly continuous delivery from this pan 9 of the mix having bonding agent therefor to flow uniformly into pockets ll. These pockets II have wall section i2 rising 50 therefrom, while therebelow are eyes l3 completing this link element of the pan carrying pins.

l4 with rollers i5, one at each side of the chain or horizontal reach of the conveyor, to travel on track l6 carried by supports II. This conveyor 55 upper reach extends from idler sprocket wheel 18 on shaft i9 positioned adjacent the supply pan 9 to sprocket wheel 20 on drive shaft 2!. Actuating this shaft 2! is motor 22 having transmission connection 23 (Figs. 6 and '7) thereto. This shaft 2! has gear wheel 24 thereon in mesh 8 withsimilar gear wheel 25 on shaft 26 to drive sprockets-21 actuating sprocket chains having links 28 between rollers 29. r These links 28 through elements 28' carry pins 38 upon which hang brackets '3l having cap 10 screws 32 mounting packer elements 33 (Figs. 4 and 8) to enter the respective pockets l i These brackets 39 remote from the pockets ll have lugs 33 in recesses 35. permitting swinging joint action on the shaft as limited by adjustable set screws 33 on opposite sides of these lugs 36. For this coaction, the presser elements 33 as complementary to the pockets II have tapered side portions 3'5 against too close clearance with beveled sides 38 of the-pockets ll. 20

This sprocket chain comprising the links 28 between the rollers 29 has horizontal reach extent from the sprocket 2'! to'idler sprocket wheel 39 on shaft lfi. These shafts 26, 40; are carried by the frame il in fixed position relatively to 25 the pocket-carrying conveyor.

Also anchored on this frame I1 is pivot pin 6! (Fig. 4) from which extends horizontally pressure applying arm 42 having inclined lower face t3 to act on the rollers 29, thereby progressively 30 to direct the path of these rollers in bringing the presser elements 33 into the pockets H,' after these pockets pass around the wheel l8,--ajndfby way of guide M at rollers 30 are allowed'gradually to enter the respective pockets M This 35 holding arm is of the general direction of=the;,-. reach of the conveyor chain directly therebelow and bearingon the rollers 29 in the nature of a self-laying track holder, termed in motor vehicle practice, of the so-called caterpillar type. 40

'As this travel in the upper reach of the pocketcarrying conveyor clears these presser elements 33 from the. guide 44, the arm 42 is effective and its pressure spring means 45 adjusted by nuts 46 on stem 41. As this arm length becomes shorter 5 toward the pivotal mounting 4|, the pressure action gradually increases in the forcing of the packer elements 33 into the pockets ii. In this continuous operation, as the rollers 29 clear this pressure arm 43, lifter incline 48 is effective at 50 rollers 30 gradually to urge the elements, 33 clear of the pockets! I so that as the'upper reach of the pocket-carrying conveyor continues to'its terminus, the pockets Il may have the sides thereof spread, as passing about the sprocket wheel 20 and thereby free the pocket so that uncom iacted mass 49, as initially entering the pockets, may as compacted mass be rolled from the pocket to fall on take-off conveyor 5| as driven by sprocket wheel 52 from the shaft 2|. This conveyor 5| may transport the formed press-molded nodule of glass melt sections to the factory floor adjacent the furnace or for storage in a bin ready to provide dustless charging material into the furnace. This means that silicosis and dangers from glass factory dust are materially minimized, if not absolutely eradicated, and there is a resultant efliciency in uniformity of melt as predetermined for the ingredients with an economy in the firing.

In lieu of the brackets 3| there is shown (Fig. 9) bracket 53 on the pin 30 coacting with special link 54 having clearance 55 for lugs 56 allowing for the suilicient swing or automatic alignment of plunger compacting or packing element 51 into the pocket as coming into packing position and also for the lifting therefrom as well as clearing of the pocket as the pressing action is completed. It is important that this compacting or packing plunger face member 33 and 51 be resistant to abrasion action of the special in-- gredients, particularly when, as herein, the lumps or nodules are of the elements for glass melt. This abrasive resistant member for the plunger as well as for the pocket is to be effective in. the duration of life for performance hereunder. even the handling of the vitreous mass for glass manufacture. This means that, in addition to the strength or compacting, there is a general hardness at least as to surface finish, or resistance to abrasion.

In this operation of the machine, in subjecting to this range of pressure it is important to avoid working of this grit into the bearings. Accordingly, the rollers l5 (Fig. 8) have overhanging flanges 58 into which extend the sleeves 59 and links l3 on the bearing pins H. Furthermore, these sleeves 59 have grooves 60 under this overhang, 58 tending to direct any passage of grit away from the end of the sleeve and away from the roller but to be thrown clear of working into the bearing.

The packing element carrying conveyor is one which, due to the grit or abrasive character of the supply material and the desire to have' such brought into effective packing relation, involves nicety for registry therebetween. To such end the respective shafts 26, 40, may be adjusted by shaft adjusting means SI for the desired nicety in this control. This compacting is desirably one conducted with the state of the material approaching that of molding sand in a foundry, that is, there is a binder content which under the extremes of pressure high per square inch, brings about a compacting short of oozing out for creating a sticky mass but effective to produce a hard smooth surface on this nodule. This assures that the character of the mix as dry assembled or compacted in this nodulizer is one which maintains the ingredients against segregation. There is thus a reliable character for the .melt to be effective, insuring an economy in fusing due to the voids between the nodules giving definite exposed surface areas as distinguished from dust blanket portions.

What is claimed and it is desired to secure by Letters Patent is:
