STICKER :BAND FOR PHOTOGRAPHIC CARTRIDGES.

Original application iiled May 24, 1922, Serial No 563,447. Divided and this application filed May 20,

1924. Serial No. 714,747.

To all whom it may concern.'

Be it known that we, JOHN G.JoNEs and HAYwoon G. DEWEY, citizens of the United State of America, residing at; Rochester, in

the county of Mo-nroe and State of New York, have invented certain new and useful Improvements in Sticker Bands for Photographic Cartridges, of which the following is a fullclear, and exact specificatlon.

Our present invention relates to an improved. sticker b-and intended particularly for use in a photo rap-hic roll film cartridge.

Roll film cartridges of a common type include long strips of interwound backing paper and film, the latter |being secured at one end by a sticker to the paper, and the other end being free but havin a sticker attached. There have been mar eted such films in which the adhesive of the first mentioned stickers was water-proof or unaffected by Water, t-he use of-such stickers rendering possi-ble the rapid assembly of the cartridge without the possiblel introduction of mois- 25 ture at .this point. It has not been possible, however, to utilize this type of sticker at the free end of the film for the reason that the permanently tacky adhesive will at once ad- -liere to the backing paper if interwound therewith. It has, therefore, been customary to use a sticker with `a water-soluble adhesive, such as glue, at this free end of the film. The use of such a sticker'necessitated the dampening of the end thereof which was to 'be attached to the film and involved certain disadvantages.

We have perfected an improved sticker intended particularly for use at the free or unattached end of the film which overcomes these disadvantages in the process of making the cartridge and whichv further improves the cartridge as a photographic article. It comprises a sticker carrying an adhesive capable of being affected by water l5 by which it may be attached to the paper when desired, but carrying also a portion coated with a permanently tacky adhesive by which it may beapplied to the film with.

out the application of water;and thus per- 0 mitting the immediate winding of allthe elements in a dryl condition.

' This ap lication is a division of our application genial No. 563,447, filed May 24,

1922, which matured into Patent N o.

1,500,393, granted July 8, 1924.

Reference will now be made tothe accom panying drawings in which the same reference characters refer throughout to the same parts.

Fig. 1 is a perspective view illustrating the process of making arartridge;

Fig. 2 is a perspective view showing a cartridge ina nearly unrolled condition;

Fig. 3 is a plan of our improved sticker;

Fig. 4 is a fragmentary view showing in section an alternative ,form of sticker in position;

Figs. 5 and 6 are sections of other alternative forms of stickers;

Fig. 7 is' a fragmentary view showing another form of sticker in position.

In the drawings, 1 indicates a spool on which are interwound a long strip of protective paper 2 and a strip of photographic film 3 attached to the paper at its end 4,

which is outermost when sold, by a sticker 5, the adhesive of which is preferably permanently tacky and unaffected by moist-ure.

The inner end 6 of the film carries a sticker 7 attached thereto,1but unattached to the protective strip 2.

Our preferred form of sticker 7 comprises a rectangular strip, as shown in Fig. 3,

along one border of which is coated a band 8 of permanently tacky adhesive material unaffected by water, and along the opposite border of which is coated a band 9 of glue or other water-soluble adhesive, leaving an uncoated intermediate portion In the process of making a'cartridge a spool 1 is laced in suitable Winding means, such as splndles 11, 12, which may be adapt- .ed for rotation by any desirable mechanism, either hand actuated or automatic, a niach-ine for operating such spindles being disclosed in the pending application Serial No. 516,229, filed Nov. 18, 1921, of Jones, one of the present inventors. The end of a strip of backing paper 2 is 'attached to the spool' HEISSUE then be pressed into firm contact with the ilm and then preferably permitted to dry. If too much Water is used, either too great an amount gf moisture will be. carried into y the cartridge/or an undesirable delay will the sticker will not adhere firmly.V

If too little-water is used Moreover, while the stickers may be positioned by automatic machinery, they are in practice placed by hand; and it is customary for the operator to press the sticker .into adhesive contact with the fingers. If this is not uniformly done over the surface, some parts will not' be stuck, especiallyif too little water has been used. As the adhesive dries rapidly, its adherent qualities decrease. All of these difficulties are overcome by the permanently tacky adhesive; no water is carried into the cartridge; no delay is desirable; and when the sticker is properly positioned on the "film and carried (into the roll, it will be pressed into firm adhesive contact by the pressure of the tight winding. It is obvious that the cartridge as a photographic article is improved, since the possibility Aof the presence `of undesirable lmoisture is greatlyfreduced. l

It is apparent that numerous modificabe necessary.

, tions may be made in the form of the sticker and we have choseny certain of the more desirable ones for purposes ofJ illustration.

The two adhesive bands need not be se arated by an intermediate uncoated portlon -and forms illustrative of this areshown in Figs. 5 and 6. K In Fig. 5 the two-coatings,

14 and 15, of waterproof and water-soluble adhesives respectivelyv are extended from` i the bordersl of the supporting strip 16 to meet at an intermediate point 17, leaving no uncoated portion, In Fig. 6, ya support 18,. preferably of paper, is uniformly coated with one type of adhesiver 19, Iandupon this is adhesively. secured a smaller stripy 20, preferably of paper coated with the other type of .adhesive 21,-this forming a stickerv having portions of each type.' This' type offers certain manufacturingl advantages.

Itis not necessary that the two adhesive coatings be on the same side/or surface of the sticker strip. .In Fig. 4 is shown a strip 22 having on one surface a border 2,3 of permanentlytacky adhesive by which, iteis attached to the end 6 of the film 3, and on theother surface and near the opposite edge coated with adhesive, one coating, 27, being of the permanently adhesive type by which the stripis secured 7to the end 6 of film 3, and the other coating, 28, being ofr the Water-soluble type and not attached to the protective strip 2.

The adhesive which .we described as Waterproof or permanently tacky, isof a well known type such as is used for adhesive tapes of various kinds. A typical composition includes rubber and coal tar pitch with any suitable softener such as benzol, gasoline or chloroform. We do not limit ourselves to any particular composition since any adhesive that yis s0 slow drying as to maintain its tackiness over a reasonable time, and the adhesive properties of which are unaffected by water is contemplated as within the scope of our invention. Similarly when we refer to Water-soluble adhesive, we intend to include any glue or paste which usually dries quickly and which becomes quickly adhesive in the presence of moisture.

It is apparent that While the sticker band is particularly adapted for the uses herein described, it is capable of other uses,` and particularly for use 4as the sealing band that is supplied at the tail .end of the backing paper as4 sold by the manufacturer. We contemplate as within the scope of our invention all'such modiications and equivalents as fall within the following claims.

Having thus describedour invention,

` what we claim as newland desire to secure by Letters Patent is:

1. A sticker for use in roll film cartridges capable of being affected by water.

. 8. A sticker band comprising a rectangular strip of paper having one surface and along one border thereof, a coating of adhesive material capable of being laffected by water and on .the same surface and along the opposite border a coating of waterproof adhesive material.

Signed at Rochester, New York, this 16th day of May, 1924:.
