To all whom may concern:

so it known that L Town A, Nissmnls, or subject the Czar of Russ-in, :1 legal res1- dent of Heisingitors, Finland, at present residing at ew York city, in the borough of Bron l State of New York, have invented certain new and useful improvements in Methods of Applying Cops to Bottles, of "which the following is a. full, clear, and ex act dcscrititioni v Tihis invention resides in an improved l lying sealing caps to bottles eels, whereby anefiective seal 1 without the aid of complicated. devices, and Without (longer the bottle.

, longer which has to obta n the iting device companies it, are dis-- ping; machine for nineoesly e cap is composed) which compresses the sealing disk between the cap and the mouth of the bottle. The downward pressure upon the intermediate portion of the flange of the cap, resisted. by the support at, the outer edge of the flange, causes the ihtermediate part of the flange to bow downward and inward toward the bottle, and thus forces the metal of the flange around the bend on the bottle, and into the depression immediatelyunder the same. This bowing or movement of the intermediate portion of the flange causes the outer edge of the flange to gradually recede from its support until finally it is entirely free therefrom, Whereupon the continued downward pressure upon the flange finally forces the latter snugly against the neck of the bottle. The capping device is a. hollow cylindrical. body which comes in contact with the flange, only, of the cap, so that in the capping operation the head ofthe bottle carrying the cap may reject through the cylindrical portion to W intever extent the length of the bottle may require, there being no plunger or other part having a. fixed stroke to interfere with the movement of the bottle with respect to the capping machine.

,lily invention; will now he described in connection With the accompanying drawing, in which:

The bottleijgrp is indicated by the numeral I, and is similar in shape :ihd construction to the commercial bottle chps, except that the flange after extending downward vertically as at 2, a, short distance, is bent outwardly zit suhstmitially right ongleo to form a horizontal rim 8, the latter being provided with corrugations it of any or the usual form, The usual pecking disk 5 placed inside of the cap, but in this section of movement. The segments groove 11, as seen in Fig. 2.

In order to explain the method of sealing it is necessary io understand the construction of the capping head. This head com prises s tube 6 carrying a, socket piece Which is provided with a conical interior chamber 8. In this chamber loomed a die 9 comprising i ce segnieiiis *hich hear against the co: alls .ioer 8. but are of slightly less hiigih ism: said Wil-llS, so that they have 21- ver 'csl play in the chamber 8, which will cause the segments of the die 9 to contract, or pee mii them to expand, depending upon the disepairsted by slight spaces 16, which are practically closed when the die is in the upper psi-e of the chamber. lower inner face of the die is provided with an enimlai groove 11 hounded below by a lo 12 and above by an overhang 13, the limbprojecting inward considerably beyond the ledge 12, and having a rounded face 14;. The vertical width of the groove 11 is such as to just admit the corrugated rim of the esp.

i5 is s retaining ring which screws onto the lower end of the tube 6 to hoid the socket piece 7 and the die 9 in place.

Referring now to the o oration, or iiietlr od of applying the cop, $31G cap is first adjusted in the die preparatory to applying it to the hottie, as shown in Fig. 1., she rim of the cap fiting friction tight into the eiitrance of the groove 11. A bottle is then placed cent-rally" below the cap and either the cspping hesdis orou ht. downward o the bottle is forced opwsr to make the ospping stroke. in either case, after the top of bottle enters and seecs Within the cop,
