Specification of Letters Patent. Patented Jl lll 27, 1922;

Application iiled November 26, 1919. Serial No. 340,776; a A

To all whom it may concern:

Be it known that I, SIGMUND L. GOLDMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im provement in Bottle Cappers, of which the following is a specification.

My invention relates, more particularly, to an instrument or implement to be used in the applying of seals tothe mouths of bottles, as for example seals known as crown cork seals which are of a construe tion adapting them to be applied to the mouth of the bottle, and thereafter contracting the seal into rigid engagement with the externally flanged portion of the neck of the bottle.

By my improved capping instrument it was intended that an instrument be provided not only which might be used for the sealing of bottles in the first instance, but also and, more particularly, to the sealing of bottles after the same have been opened, by the use of the same sealing cap. v

In this connection it may be stated that without the use of an appropriate tool or implement it is not possible to reapply to sealingposition a seal once removed froma bottle, this condition rendering it highlydesirable that an implement adapted to reseal bottles be provided which, especially for use in the household, should be of simple and economical construction and not require skill in the use of same.

My primary object is to provide a novel, simple and economical construction of tool or implement which may be used without skill for the crimping of seals about the mouths of bottles, which will be very durable, by which the sealing may be effected without danger of injuring the hands of the operator, even should the bottle break, and which will reduce to the minimum danger of the breaking of bottles.

Referring to the accompanying drawingz-Figure 1 is a View, partly broken away, of the upper end of a bottle .to be sealed, showing a seal applied to initial posi tion thereon and engaged by my improved capping implement, the parts being shown in the positions they assume upon their assembly but before any force is applied to the capping tool for crimping the seal; and Figure 2, a view in vertical elevationof'the structure ofFig. 1, showing the seal and the capping tool in the positions they occupy at the conclusion of the peration of sealing the bottle. 7

Asa preface to the following[description of my capping tool it may be stated that the sealcap illustrated in. the drawings and reptending projecting parts 6 alternating with the outwardly projecting parts 7, with a disk 8 of cork or othersuitable resilient material at which the seal rests against the outer end of the neck of the bottle.

My improved device, which is provided for the purpose of engaging the portions 7 of the seal and by crowding them inwardly, force the portions 6into interlocked position with the flange 5 of the bottle, is represented at 9 and is generally of cup form, it being by preference made, as by drawing it, from one piece of comparatively resilient sheet steel of a relatively heavy gauge, as for example and by preference No, 15 gauge. The device 9 is of circular shape incros'ssection, its upper, closed, end being of doine shape. Its lower, open, end at the portion thereof which engages the part 7 ofthe cap 3 is relatively thick throughout the circumference of the tool, as compared with the thickness of the remaining part thereof as represented at 10, this portion of the tool outwardly flaring with its inner surface rounded off at 11 as represented. In the forming of the tool it is so shaped as to present, by providing its lower end portion of enlarged diameter, more or less abrupt

annular shoulders

12 and 13 located at the outside and inside respectively, of the tool.

In the use of the tool the seal 3 with the disk 8 therein is applied to the; mouth of the bottle to the position shown in Fig. 1, and the cappingtool then applied to position on the seal as shown in this figure. Theop erator, grasping the capping tool between the thumb and first finger of the hand above the shoulder portion 12 of the tool, strikes the tool at its upper dome-shaped end as by hitting it with a hammer to forcethe tool downwardly, the latter in this o eration, by riding do'wnwardly'against the pertions 7, forcing these portions inwardly and causing the portions 6 to become interlocked with the shoulder 5 of the bottle as represented in Fig. 2, whereupon the operator may readily remove the tool from the seal.

By making the lower skirt portion of the capping tool as shown and described and forming the portion thereof at which it engages the parts 7 of the seal, relatively thick,

the skirt portion of the seal 3 is prevented from becoming impaired as by cutting and danger of the splitting of the metal of the skirtportion of the capping tool is avoided. Furthermore, the capping tool is rendered very durable and lasting, as by constructing it as described it is rendered relatively resilient and to such degree that while the force necessary to effect a proper clamping of the seal about the bottle is exerted against the seal, danger of breaking the bottle is reduced to the minimum.

The feature of providing the capping tool of dome-shape also presents the advantages that the hammer, used in operating the capping tool, will always strike the tool in the center causing the capping tool to operate against the seal with uniform pressure throughout the circumference of the seal, thereby insuring the proper positioning of the seal on the bottle, and that the hammer will not glance off the capping tool and strike the hand of the operator as it would be apt to do if the upper end of the tool were flat. Furthermore, by reason of the construction of the capping tool as shown and described, the oftener the tool is used the harder and stronger it becomes, even if it flattens slightly.

The provision of the shoulder 12 is of advantage in that it operates as a stop or rest for the fingers of the operator, maintaining the fingers in place on the seal and enabling the operator to maintain the seal firmly and level over the bottle to be sealed without the fingers slipping; and the provision of the internal shoulder 13 is of advantage in that it acts as a stop in the capping operation in the event of excessive force being exerted against the tool in the capping operation preventing the capping tool from descending to such an extent on the seal 3 that wedging of the seal in the capping tool, and consequent difficulty of the withdrawal of the capper, results.

- The feature of providing the flaring open portion of the tool, of larger internal diameter than the greatest diameter of the seal with which it is to be used, and avoiding the contact of a sharp edge thereof with the seal, as shown in the drawing, is of advantageas thereby tearing or cutting of the skirt of the seal, is prevented.

lVhile I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto, as the same may be modified and altered without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is:

1. A capping implement for the purpose set forth, having an integral hollow domeshaped portion forming its closed end, the implement presenting a space between its closed end and the top of the cap.

2. A capping implement for the purpose set forth, formed of relatively resilient metal and having an integral hollow dome-shaped portion forming its closed end, the implement presenting a space between its closed end and the top of the cap.

3. A capping implement for the purpose set forth, comprising a member formed of relatively resilient metal having a hollow dome-shaped upperend and having its opposite end open and at which it is adapted to engage the seal, the wall forming said open end being relatively thick, thereby to render said implement highly resistant to distortion and splitting and highly durable, the implement presenting a space between its closed end and the top of the cap.

4:. A capping implement for the purpose set forth, comprising a member formed as an integral structure from a sheet of relatively resilient metal, said member having a hollow dome-shaped upper end and having its opposite end open and at which it is adapted to engage the seal, the wall forming said open end being relatively thick, thereby to render said implement highly resistant to distortion and splitting and highly durable, the implement presenting a space between its closed end and the top of the cap.

5. A capping implement for the purpose set forth, comprising a member formed as an integral structure from a sheet of relatively resilient metal, said member having a hollow dome-shaped upper end and having its opposite end open and at which it is adapted to engage the seal, the wall forming said open end being relatively thick, and the open end of said tool being outwardly flaring, with the larger internal diameter of said flared part greater than the larger diameter of the seal with which the tool is to be used, the implement presenting a space between its closed end and the top of the cap.

6. A capping implement for the purpose set forth, formed of a member constructed from a single sheet of relatively resilient metal, one end of said memberbeing of dome-shape and its opposite end open at which it engages the seal, the wall of said member at its open end being relatively thick and its inner surface flaring outwardly, the side-wall of said member being deflected into expanded condition between its ends and presenting an external and an internal shoulder.
