4 B. DEWEY METHOD OF ADHESIVELY SECURING ARTICLES TOGETHER Filed March 22 1920 like characters on Patented Aug. 26, 1924.




Application filed 18.1'01122, 1920. Serial no. 367,863.

,To all whom it may concern;

Be it known that I, BRADLEY DEWEY, a citizen of the United States, residing at Cambridge, in the county of Middlesex and 5 State of Massachusetts, have invented an Improvement in Methods of Adhesively Securing Articles Together, of which the following description, in connection with the accompanying drawings, is aspecification, the drawings representing like parts.

' The invention to be hereinafter described relates to a method of adhesively securing photograph prints, sheetpaper and other articles to mountings of paper, metal andother materials.

Heretofore, considerable difficulty has been experienced in mounting photo'prints. Usually the adhesive which has been employed for this urpose is paste, mucilage or glue, all of w ich contain a substantial percentage of moisture. One of these adh'esives is spread over the back of the print, and the moisture therein is absorbed by the 2 paper, thereby causing the same to expand or warp after the print has been applied to the mounting, thereby causing objectionable wrinkling or puckering of the paper. Sometimes the grain of the superimposed paper will run parallel to the grain of the paper mounting, and sometimes transversely thereof. In both cases wrinkling is liable to occur, and in either case when the mois ture dries from the pa er, the latter tends to contract, and this e ect may be greater in some portions than in other portions of the paper, thereby causing irregular contracting, so that as a consequence, when the adhesive has dried and set, the paper print is liable to be left in a wrinkled. condition. Also, the character of certain adhesives heretofore used, has been such that it is difiicult uniformly to spread the same over the back of the print, and portions covered by less adhesive than others are apt to bulge away from the mounting, and especially adjacent the edges of the paper print where the dryin effect is more rapid than in the body of t e paper print a substantial distance within the edges thereof.

In the use of paste, mucilage or glue, care 'must be exercised to coat the back of the paper print completely tothe edges thereof inorder that the latter may not curl up away from the mounting with disfigurefi'ect.- In applying the adhesive coat-- ing at the edges,

there is danger thatan excess amount of thereto, so that when the paper print 1s pressed against the mounting, the adhesive will squpeze be nd the edges onto the mounting and disfigure the sameis difficult, if not impossible,'to remove such excess adhesive from the mounting. withoutv giving the same a soiled or unsightly appearance.

adhesive will be applied Also, a

The aim and purpose of the present invention, therefore, is to provide a method whereby prints and other sheet paper articles may be quickly and readily applied to mountin 5 without the objections referred to, atten in the use of adhesives heretofore employed. 11 carrying the invention into practical, effect, a rubber containing adhesive is employed which contains little or no moisture, and therefore, does not have the objectionable wrinkli effect referred to. In .the use of is unnecessary to exercise care to prevent excess adhesive from working out at the edges of the print onto the mounting. This is because the rubber adhesive may be readily rubbed from the mounting, and "instead of soiling the mounting the adhesive has a cleaning or erasing effect due to the fact that when the rubber adhesive is rubbed it will crumble or roll up into little particles .to which the dirt upon the mounting adheres, and these particles may be readily brushed away.

The character of the invention may be best understood by reference to the following description of the method in "connection with the accompanying drawings, wherein:

Fig. 1 .is a perspectlve View ofa mounting and an inverted print thereon, illustrating the step-of applying the rubber cement to the back of the print;

print thereon having the adhesive coating in contact with the mounting and showing the excess adhesive on the mounting adjacent the edges of the print; and

Fig. 3 is a plan of the finished article.

In the riate ru ber adhesive may be employed.

no good form of such adhesive may comprise the following ingredients,- -one-third 2 is a plan of the mounting with the practice of the method, any appro-' this ru ber adhesive it in the present instance of the invention, ior

' other material.

purposes of illustration, the method is employed to secure photograph prints to mountings whichmay be of paper, metals or To apply the adhesive to the print 3, the latter is inverted, and desirably superposed on the mounting 5 to which it is to be secured. Then the adhesive may be squeezed from the tube container onto the back of the print in sufficient amount to rovide a coating 7 covering the same. This coating may be spread or distributed by means of the finger or a brush, andprefrably the adhesive is so applied as to extend beyond the edges of the mounting and cover p'ortions of the mounting adjacent said edges, as indicated at 9. The character of the rubber adhesive is such that it may be readily spread over'the back of the the form of a thin layer or coating.-

Afterthe adhesive has been applied as described, the print is reversed, and placed on the mounting with the rubber adhesive coating in engagement therewith. The print may-be pressed against the mounting so as to have secure adhesive engagement therewith, and pressed "out beyond the edges of the print ontothe mounting without objection. Then the adhesive is allowed to stand .a few mo- [ments to allow the rubber adhesive to dry.

Then any adhesive which may be onthe mounting adjacent the edges of the print may be rubbed therefrom by the finger or any appropriate means, and this adhesive will roll from the mounting with eraser-like effect, and leave the mounting in clean condition.

v Heretofore, so'far as I am aware, it has beenimpossible satisfactorily to secure prints, labels and other sheet paper articles but by the present to tin and other metals,

method employin rubber adhesive, such articles may be e ciently secured to metals,

tract the paper and pull t mounting in any excess adhesive may be due among other things to the fact that the character of the adhesive is such that it does not contract in dryingland does not cone same relatively to the metal mounting. v

The rubber adhesive not only constitutes efiicient means for securing the sheet paper article to the mounting, but also prevents ingress of moisture to the adhesive, whereas, in the use of paste, mucilage or glue, any ingress of moisture thereto between the sheet paper article and mounting is liable to weaken the adhesive and allow portions of the sheet paper article to escape from the mounting.

The mounting maybe of any desired character, and when sheet metal mountings are employed, they may be flat or curved or of I other form as desired.

While the method has been described for purposes of illustration in the application of photo prints to mountings therefor, it I will be understood that the invention is not limited thereto.

What is claimed is 1. A method of securin ferentareas together, 0 aracterized by spreading on thesurface of one of the articles a thin'coating of viscous rubber adhesive containing a solvent, ressing the articles together with the rubber adhesive between them 1 at normal temperature and before the solvent has evaporated, thereby to unite the articles and cause any excess rubber adhesive to creep beyond one ofthe articles ontothe other, and rubbing the excess rubber adhesive therefrom after it has dried.

2. A method of securing a sheet of ma-- -terialon a mount, characterized by spreadarticles of air-- solvent has evaporated, thereby to unite the sheet and mount and force any excess adhesive beyond the margins of the sheetonto the mount, and rubbing the excess rubber adhesive from the margins of the mount after it has dried.

In testimony whereof, I have signed my name to this specification.
