oApplication led November 27, 1911. Serial No. 662,654.

ed certain new and useful Improvementsvin Paraining-Machines; and we do declare the following to be a full, clear, and exact de-l scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specilieation.

ln the manufacture of paper receptacles for liquids, especially when the receptacles are designed to be used as milk-bottles, it is necessary that the receptacles be thoroughly coated with parain or like substance andfor economic reasons-that the operation should be performed rapidly and cheaply.

To this end, our invention -consists of the construction, devices and arrangement of parts hereinafter described, and shown and illustrated in the accompanying drawings, in which, y

Figure l is a side-elevation of our machine with portions of the case and tank, hereinafter referred to, removed or brokenaway; Fig. 2, a top-plan view of the same; Fig. 3, a perspective view, on an enlarged scale, of the bottle-holder hereinafter referred to, detached; Fig. 4, a like view of a portion of the carrier-chain hereinafter referred to, and Fig. 5, a central vertical sectional elevation of a portion of the discharge chute hereinafter referred to, illustrating the. means for retarding and directing the fall of the freshly coated receptacles.

Like parts are represented 'by corresponding reference numerals throughout the several views.

In the drawings, 1 is a tank, preferably of sheet metal, open at its top, having, preferably, a rounded bottom and being suitably supported within another tank 2. The inner paraiiintank,-forillustration,-hasaflanged ring which rests upon the top of the hot water tank 2. rIhe latter tank is bolted or otherwise secured in place within the frame of the machine. The water tank 2 is provided with steam pipes 3 by which the contents of the Water tank are heated to melt and to heat to the required temperature the paraflin in the tank 1.

l is an endless belt which maybe constructed of any suitable material, but is preferably composed of a chain made up of links which, for illustration` may be formed,

as shownin Fig. 4. The belt 1 travels over pulleys 5, 6, 7 8, 9 and 10. rl`he pulley 7 is broad, as shown, and its shaft 11 is mounted and journaled across the tank 1 at an angle to the line of theV travel of the belt, so that the belt or chain traverses a spiral path around the pulley, entering between the flanges of the pulley at one side of the pulley and leaving the pulley at the opposite flange, as clearly illustrated in Fig. 2. The pulley 7 is submerged, or nearly so, in the melted paraflin. One of the pulleys,-in the present instance, 9, is mounted upon the driving shaft of the machine which is revolved by any suitable driving mechanism.

Secured to the outer side of the belt 1. at equi-distant intervals, are metal frames or grids 12 having holes 13 which correspond to and coincide with holes 11 in the links 1 i 15 in the chain or belt and by means of which the parts 12 are securely bolted or riveted in placey upon the belt or chain.

Projecting outwardly from the parts 12 and radially from the several pulleys over which the belt passes are resilient prongs 16, spaced apart around the frame in such fashion as to provide between them a space for the reception-with a loose fit-of the paper receptacles a to be treated.

The frame of the machine, consisting of suitable angle-bars and which supports the gears and belt hereinbefore described, also supports the side, end and top coverings composed, preferably, of sheet-metal. The case or covering is open at its front en'd, that is, the end where the operator stands, seen at the left in Figs. 1 and 2.

At the bottom of the machine is a drippan 17 into which, at opposite ends, lead the inclined plates 18 disposed beneath the receptacles to a point where they are to be filled -or otherwise disposed of. In milk traiic the paper bottles, fresh from the hot paraflin, aremoved on the belt 21 to such distance and for such time as to permit them to cool suiiciently to be filled with milk.

rIhe advantage of at once 'iilling and sealing the receptacle is manifest, the receptacles being now absolutely clean and sterile and the contents protected from contamination. The operation of our device, thus far described, is as follows. The paran being heated to the proper degree and the beltlbeing -in motion over its several pulleys in the direction of the arrows, the bottles'a, as fast l as the holders 12-16 present themselves to the operator, are slipped-mouth forevmost-between the prongs 16 vofthe holders.

The bottles proceed upwardly over pulley 6 thence downwardly, with the bottom inclined upwardly, around the pulley 7 and .into and through lthe bath of melted araffin, In its course through the-para the bottle is gradually turned with its mouth'.

upwardly so that the bottle becomes filled with paraflin. As the bottle emerges from the paraiin its mouth is turned downwardly so that the bottle is now emptied. The bottle now proceeds upwardly over the top of. the pulleys 8 and 9. As the bottles leave theturn yof the pulley 9, they, by .their own weight, slip downwardly away vfrom the holders into the trough 20 and onto the belt 21. To retard the fall of the freshly coated mareas are again in succession supplied with the bottles to be treated. During the course of the bottles horizontally from the pulleys 8 to 9, the belt, the holders, and the bottles are dripping with hot paraffin. These drippings vfall onto the inclined plate 24 and run back into the tank 1. Any further drippings from the belt and holders are caught upon the inclined plates 18 and run into'the drip-pan 17.

I-Iaving described our invention, what we claim and desire to secure by Letters Patent is,-

1. In a machine of the described character, a tank, an endless chaing'holders upon the chain adapted to receive-mouth` foremost-containers of the character described, pulleys which guide the chain and its holders forwardly and downwardly into the tank, then backwardly, upwardly and forwardly outv of and away from the tank,A

whereby such A containers describe a complete revolution in their course into 'and out of the tank and whereby they enter and recede from' the tank with their mouths turned downwardly.

2. In a. device of the described character, a tank, an endless chain, carriers on the chain, a series 0f pulleys for supporting and directing the chain, said series including a pair `of\pulleys disposed above the tanks in parallel planes, and a -pulley with- -in the tank' having its shaft disposed at an angle to the line of' movement of the chain. v'In testimony whereof we aiix our signa` tures in presence of two Witnesses.-
