PHoToGRAPH'Ic-PAPBR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, H. llL-HEDDEN, of the city and county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Iniprovements in Photograph-Paper; and I do hereby declare that the following is a full, clear, and exact description of the same, reference heilig had to the accompanying drawings, forming a part of this spccifcation, in which- Figure l represents a perspective view of a piece of my improved photograph-paper, with the upper part ot' it separated, to illust-rate and show more fully the character ofthe paper as hereafter explained;

Figure 2 represents, upon an enlarged scale, a section of a pieceof my improved photograph-paper, as hereafter explained; and

Figure 3 represents a sectionof a card, after the picture has been taken on my improved paper, and mounted or pasted upon the card. i

To enable those skilled in the art to which my invention belongs, to make and use the same, I will proceed to describe it more in detail.

A represents a piece or strip of my improved photograph-paper, which is made of two strips B B, of card or Bristol-board, composed of fibres of fine or hard texture.

The two strips or layers B Bare united to a central piece of paper, a, of a loose pulpy nature.

The paper thus niade is prepared on both sides, the same as if pictures were to be taken on both sides, whereby the inner layer a, as well as the insides of the strips or layers B B, are f'ully protected from the action of both water and the chemicals used or employed in the process of taking the pictures.

After the picture hasy been taken on one side, and preparatory to being mountedv upon a supporting-card, the two pieces or layers of papel' B B are torn apart or separated, and which operation can be easily effected, since the loose pulpy fibres, compassing the layer of papers a, yield quickly when and as soon as the layers B B are drawn apart, as indicated in figs. 1 and 2 of the drawings.

It will be observed,'by reference to the drawings, that a part of the loose, fibrous material, composing the central layer a, adheres to the inside of each of' the layers or stripsB B, thus furnishing the proper and desirable surface for receiving the paste or adhesive substance, by means of which the piece of paper or card-board, upon which the picture is taken, is properly secured to the card O.

The pieces or strips of paper or card-board B, which are separated from those upon which the pictures have been taken, as above described, can then be pasted together apd out up for taking taking small'pictures, similar to those called tin-types, whereby all, or nearly all the paper-stock can be utilized and saved. Those skilled in the art to which my invention'helongs will readily understand and appreciate the importance and value of ni'y invention.

The pictures taken on my improved paper are those called positive pictures, and the paper or card-board,

as heretofore made and used,l1as been covered with' 'varnish or some other resisting material on the back..

to protect the fibres of the paper from the act-ion of the water and chemicals used during the operation of taking and preparingfthe picture, and artists find it very difcult to paste the paper thus coated upon a supporting-card, in such a manner as' to secure it in such position for any great length of time, in a neat and tasty manner.

Then, again, by the use ofv my paper, the surface upon which the picture is taken, especially when several picturesare taken upon one sheet of paper, is retained in a very uniform and even manner, owing to the fact that the card-board or paper is comparatively quite thick as used during the process'of taking the pictures. This last feature, the thicknessof the paper, which would be objectionable, as reuderig the picture, when mounted Vupon the card, thick and clumsy, is entirely obviated by the separation of the paper, as above explained, preparatory to mounting the picture upon the supporting-card. I am, therefore, able to obtain a more perfect picture, and at a reduced cost and expense, by the use. of my improved photographpaper, while, at the same time, all of the objections incident to the varnishing or coating of the surface of the paper which is to rcceive the paste by which the picture is secured to the Supporting card, are obviated.
