BOTTLE-CAPPING MACHINE.

Specification of Letters Patent. Patented Sept. 23, 1919.

Application filed August 8, 1916. Serial No. 113,726.

My invention relates to machines adapt-v ed to seal the mouths of bottles by means of caps having corrugated rims. One of the objects of my invention is to provide a machine of this character with an improved means for holding a bottle sealing cap; another' object is to provide an improved capping die adapted to force the rim of the cap over the lip of the bottle; a further object is to provide improved means for forcing the bottle with the cap outwardly of the die.

lVith the above and related objects in view, my invention comprises the construction, combination and arrangement of parts, a practical embodiment whereof is illustrated in the accompanying drawing and embraced within the scope of the appended claims.

In the said drawing Figure 1 is a side elevation of my machine; Fig. 2 is a fragmentary vertical section thereof; Fig. 3 is an inverted plan of my improved mounting die and ejecting device, and Fig. 4 is a view of a cap adapted to be mounted by means of my improved machine.

Referring more particularly to the drawing for a detail description of my invention 1 represents a pedestal, 2 represents its base which is slotted for clamping onto a table or bench, 3, 4 represents a winged bolt adapted to clamp the base to said bench, 5 represents a bracket provided with a vertical guide 6, and with a horizontal bearing 7 8 represents a vertical rack movably supported by the guide 6, 9 represents a platform mounted on top of the rack, 10 represents a shaft supported by the bearing 7, 11 represents a gear mounted on the shaft in mesh with the rack 8, and 12 represents a lever for operating the gear. The pedestal is provided with a head 13, centrally above the platform 9. 14 represents a cap holder provided with a horizontal opening for inserting a cap. The holder 14 is provided with a sleeve 15 extended upwardly thereof and of a diameter larger than that of the holder and approximately equal to that of the flange 13 of the head, whereby the holder is suspended from the head. The holder is provided with a contracted rim 16, adapted to support the rim of a cap. The rim 1G is then expanded into a conical hood .17. The mounting die comprises a hollow cylinder 18 adapted to be projected through the bore of the head and is provided with perforated top above the. head and with a conical rim 19 bearing against the bottom of the head, and a flange 2() is projected downwardly of the rim. The flange 20 is in the form of two frustums of cones having a common small circle. The flange 2O is slotted, said slots extending radially along the rim 19 to a distance where the solid unslotted portion of the rim is of a diameter equal t0 the diameter of the small circle of the concs.

The ejector comprises a disk 21 provided with a perforated hub 22. The disk is countersunk to be flush with the head of a bolt 23 adapted to beprojected through the perforated top of the cylinder 1S, the projecting portion of the belt. being threaded for a nut. 24 adapted to suspend the ejector under the rim 19 and within the small circle of the flange 20. Inside the cylinder 18 is mounted a spring coil wound on the bolt 23 between the top of the cylinder 1S and the top of the hub represents a cap mounted over the projecting portion of the cylinder 1S.

The cap shown in Fig. 4 comprises a circular top 2G, a fiange 27, and an expanded corrugated rim 2S.

Having thus described my machine, it is operated as follows The bottle 30, is mounted on the platform with its mouth centrally under the expanded mouth 17 of the holder, a cap is inserted through the opening of the holder with its rim on top of the contracted rim 16 of the holder. The lever 12 is then forced downwardly to cause the gear to move the rack 8 upwardly. The upward movement of the rack carries the bottle with its mouth against the cap and forces the cap upwardly within the lower portion of the flange of the die. By exerting sufficient pressure upon the lever 12 the cap is forced through the small circle common to the fiange 20, and the rim of the cap is forced by this contracted portion of the flange over the lip of the bottle, at the same time the ejector holds the top of the cap flush against the mouth of the bottle. The'spider'legs formed by slotting the iiange and a portion of the rim of Y the die permits these legs to articulate VVslightly at the junction with the rim of the die. 'As the cap is forced through the small circle of the flange 20, the ejector is fo-rced upwardly against the bottom of lthe rim of the die, and its hub is forced within the cylinder 18 thus compressing the spring. The lever is then moved inthe opposite di- Y rection, thus releasing the pressure on the ejector, the spring then expands, causing the ejector to' force the cap outwardly of the die. The platform can then be lowered by the further" downward movement of the lever until'the top of the bottle is below the holder, when it is free to be removed. Y

That I claim as new and desire t0 protectby Letters Patent, is Y l. In a capping machine, a vertical bored head, a hollow `cylinder projected through the bore of the head, lsaid Ycylinder eprovided with a perforated top above the head 'and witha conical rim below the head bearing against the bottom of the head, a flange extended downwardly ofthe rim, said iange comprising a pair of 'frustums of a cone having a common small circle, said ange being divided into vertical sections by slots small and a large diameter and adished plate connecting them, the small 'diameter being. oriiiced for the reception olf-an' ejector and slots running longitudinally the full length of the large diameter and through part of the dished plate forming a resilientgmouth, theY large diameter being bent inwardly and then outwardly on al circle near its open end, the inner diameter ofsaid circle being'smaller than theV diameterv of a bottle cap. Y

In testimony whereof I have signed this specification in the presence of two subp scribing witnesses. A
