PAPER-BoTTLE-sEALING MACHINE.

Specification of Letters Patent.

Patented Aug, 12,1913.

Application filed November 27, 1911. Serial No 662,64?

To all wrwm it may concern: I

Be it known that we, FRANK N. vll'izis WEILLIAM C. Wars, citizens of the United States, residing at Monroe, in the county of Monroe and State of Michigan, have invented certain new and useful Improvements in Paper-Bottle-Sealing Machines; and we do declare thefollowing to be afull, clear, and exact description 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 specification.

The bottles upon which our machine is intended to operate are intended, among other things, and, more particularly, to contain milk, and are composed of parafiined paper. The bottles may be of apy desired shape in cross-section, but preferably are square. The tops of the bottles may be flat or rounded but are,to facilitate emptying,preferably' slightly conical, the cone being truncated by a round hole through its apex. The bottle being filled, it is necessary that it be closed and hermetically sealed, and-when large uantities of milk oiother liquids are handled-it is necessary that this be done rapidly and cheaply. I

To effect this is the object of the present invention.

Oui invention is designed, more particularly, to close and hermetically-seal a number of these b0ttles,-say a dozen,-simultaneously and by a single stroke of a lever. The sealing devices to be appliedconsist of cup-shaped flanged stoppers composed of paratfined paper. The flange of this stopper rests upon the margin of the hole, above mentioned, with. the cup-shaped body-portion projecting down through the top of the bottle.

A" further object of our invention is to provide means for expanding this cupshaped body-portion within the bottle' so that the stopper may not be removed without visibly rupturing the mouth of the bottle, (to prevent improper re-use,) and, at the same time, to press the flange ofthe stopperdown upon the top of the bottle and, by the application of heat, to melt the paraffin upon the contacting surfaces of the stopper and bottle, thus further securing the stopper in place ma hermetically sealing the bottle.

\Ve accomplish the objects above indicated by means of the devices, construction and arrangement of parts hereinafter described,

and shown and illustrated in the accompany- 1 ing drawings, in which Figure 1 is a fronbelevation of our ma chine, showing one of the presser-sleeves or plungers-hereinafter referred to in central vertical section, to show its internal arrangement, also disclosing one of the paper receptacles hereinafter referred to together with its stopper in central vertical section, also the case or box which holds the bottles, which case is broken away to exhibit its contents; Fig. 2, a side-elevation of our machine seen from the left in Fig. 1; Fig. 3, atopplan view of. the same; Fig. 4, a central vertical sectional elevation, on, an enlarged scale, of the presser-slecve or plunger and the expander hereinafter referred to, de-

tached, with the expander collapsed, and

Like numerals indicate like parts throughout the drawings.

A pedestal 1 has bolted to its top a table 2, having at two opposite sides an inwardly turned flange 2* serving as guides for a sliding table 3 having upwardly -projecting stops 3 spaced apart exactly such distance as to receive the bottle-case a. This'box, in the present instance, is adapted to hold three rows of bottles a, there being four bottles in each row. The sliding table 3 is arranged to move toward and away from the operator, at the front of the machine, that is, to the right of Fig. 2. The inward movement of the table 3 is limited by set-screws 3*, the adjustment of which serves to stop the several bottles to be closed and sealed in exact vertical alinement with their respective sealing devices.

At opposite sides of the table. 2 are standards5 and atits rear end is a standard (5. These three standards support at their top a flat rectangular steam-chest 7, connected with inlet and outlet .steam pipes 8. Through this steam-chest are verticrl cylindrical passages 9,-in the presentinstance twelve in number,in each of which reciprc cates a device now to bedescribed.

10 is a cylindrical presser-sleeve or plunger securely fastened at its top bynuts ll to a the expander inits plate 12", as shown in detail in Figs. 4: and

to conform to the top of the bottle a and the cavity of. the cup-shaped paper stopper 0. The sleeve 10 is bored axially for the recep- .tion of 'a' plunger 13 which reciprocates therein. At its upper end the plunger 13 is threaded and by means of nut 14 is securely attached to a horizontal plate 15. At its lower end the plunger 13 flares downwardly, as at 16. The bore of the sleeve 10, at its lower end, is enlarged to form a chainber 17 in which is a sleeve 18 surrounding loosely the plunger 13 and held rigidly connected with the sleeve 10 by means of screw 19. The sleeve 18 is split, as at 20, to form downwardly projecting resilient fingers 21 the lower ends of which are turned outwardly, as at 22. The fingers 21 at their lower ends embrace and conform to the inclined portion 16 of the plunger 13.

If a paper bottle, such as is illustrated in Figs. 4 and 5, be placed directly beneath and in alinement'with presser-sleeve 10 and if the sleeve be now depressed, the flange of the stopper I; will be pressed tightly down upon the top of the bottle, as illustrated in these figures. This movement of the pressersleeve 10, and 'with it the plunger 13, is accomplished by the movement of the plates 12 and which carry all of the plungers, which movement is effected by the mechanism now to be described.

Secured to opposite sides of the steamchest 7 are upright arms or brackets 23 atthe top of and between which is j ournaled a shaft 24. Near opposite ends of this shaft are rigidly secured, asat 25, forwardly projecting arms or levers 26, between the forward extremities of which is journaled, as at 27, a shaft 28. Rigidly secured to the shaft 28, midway of its length and extending'forwardly within reach of the operator, is a hand-lever29.

-30 are arms rigidly secured at their forward ends tothe shaft 28 and extending backwardly and overlapping, as at 31, a

portion of the levers 26. Pivotally secured to the lever 26, as at 32, (see Fig. 2) are rods 33 which pass up through the overhanging portions 31 on the arms 30. Each of the rods 33 is threaded at top to receive a, nut between which. and the part 31 is a coiled compression-spring 34. livotally secured to the arm 26, as at 35, are downwardly extending links 36 which, at their lower -ends,[ are pivotally secured between lugs 37 formed on the top of the plate 12. Pivotally secured, at 38, to the arms 30 are dmvnwardly extending links 39 pivotally secured between lugs 40 on the top of the plate 15. Now, to lower the presser-sleeves 1.0 upon the top of the bottles, the hand lever 29 is pressed downwardly, to the position indicated by the lower dotted lines in Fig. 2, swinging the arms 2630 upon the fulcrum furnished by the shaft 24, and,

plates

12 and 15 together.

through the links36 and 39,-lowering the When the presser-sleeves 1O strike the top of the bottles a with sufiicient force, adjusting screws 41 in plate 12 come in contact with the top of the steam-chest 7 and arrest the further downward movement of the plate 12. A

further downward movement of the handlever 29 overcomes the resistance of the compression-springs 34 and now the arms 30,

fulcrumed on the shaft 28, swing upwardly mach-through the links 39-lift the plate 15 and with it the several expansion-plungers 13 secured thereto. This upward movement of the expansion-plungers, by their wedgelike action upon the resilient fingers 21 forces the lower ends 22 of these fingersend of which is a counter-weight 44. When the hold upon the hand-lever 29 is released, the springs 34 depress plate 15 and plungers 13, thus collapsing the expanders; the counter-weight rotates the shaft 24 which throws upwardly the arm 26 which, in turn, catches the arm 30. Now the shaft 28 and the hand-lever are thrown. upwardly into the position indicated by the upper dotted lines in Fig. 2, thus lifting

plates

12 and 15 and the several plungers out of the way so that the'box 4 and its now sealed contents may be witlidrawn, leaving the machine ready for the reception of another box of bottles.

It should be understood that the steam circulating through the steam-chest 7 keeps the plungers and expander-s quite hot, and that when these heated parts come in contact with the paratfined surfaces of the bottle and stopper, the paraffin is melted to seal the package- The heat of the expanders also assists in the stretching and setting of the paper stopper in its expanded form.
