CASE FOR PHOTOGRAPHIC SENSI TIZED PAPER.

SPECIFICATION forming part of Letters Patent No. 337,963, dated March 16, 1886.

Application filed August 19, 1885.

To all whom, it may concern:

Be it known that we, WILLIAM H. LEWIS and ERASTUS B. BARKER, both of the city, county, and State of New York, have invented a new and Improved Case for Photographic Sensitized Paper or Tissue, of which the following is a full, clear, and exact description.

Our invention consists of a light-tight box havingalight tight passage-way for the movement of the paper sheet into or out of the box, and which is light-tight both when the sensitized sheet is wholly within the box and when it is being moved in or out of the same; and the invention comprises various constructions and combinations of parts, including a roller within the box as above for carrying the sensitized sheet, and which is made capable of being operated from the exterior of the box for drawing in, out, and storing the paper or sheet.

The invention also includes various other constructionsand combinations of parts, whereby the efficiency of the case is very perfectly secured, substantially as hereinafter shown and described.

The invention is applicable to carrying, preserving, and supplying as required all kinds of flexible sensitized tissue or paper, whether sensitized on one or both sides, and whether used for making negatives or for photographic printing.

Reference is had to the accompanying drawings, which form part of this specification, like letters of reference indicating like parts throughout the several figures of the drawings, and which illustrates one form or construction of the case embodying our invention.

Figure 1 represents a view in perspective of the case closed as constructed in the form we prefer, said View also showing a portion of the flexible sensitized tissue or paper carried by the ease as in the act of being drawn therefrom, likewise showing a key used in connection with the case detached. Fig. 2 is a perspective view of the case when open; Fig. 3, a longitudinal vertical section of the case closed; Fig. 4, a back view of the same; and Fig. 5 a vertical transverse section upon the line at a: in Fig. 3. Fig. 6 is a transverse sectional view upon a larger scale of the roller which carries the paper, showing more es- Serial No. 174,802. (No model.)

pecially a special construction of it for attachment of the paper to it.

The case, as shown in the drawings, is mainly made up of an oblong box or body part, A, and corresponding-shaped lid part A, hinged to the box part in the rear, as at a a, and passing at its ends when being closed down within plates 1) b, secured to the ends of the box part. The box or case, whether thus or otherwise constructed, is to be provided with a longitudinal passage-way for the movement of the paper to and from the interior ;of the box, and this passage-way is made light-tight in any suitable manner. One method of making said passageway lighttight, and the one which we prefer, is shown in the drawings, and may be described as follows: L is a longitudinal opening or slot in the box, the upper edge of which is fitted with a packing strip or wiper, I, of soft flexible material, such as cloth, and which forms the upper lip of said passage-way. Said wiper, as for instance, when the longitudinal openiiig L is formed, as shown, in part by the lid and in part by the body or box part of the case, may be secured in any suitable manner to the interior of the lid. Immediately below andin contact with said wiper I is asnlall longitudinal roller, H, which is journaled at its ends in the end plates, b 'b, of the box. Said roller H constitutes the lower lip of the passage-way, and this roller, together with the wiper l, are so adjusted in respect to each other that there is a passage-way, 0, between them for the paper, which passage-way is light-tight both when the paper is introduced between the roller H and wiper I and also when the paper is wholly withdrawn from between said parts.

To prevent the access of light to the interior of the box at the lower surface of the roller H, We arrange another longitudinal wiper, J, of suitable soft material, to bear against the under side of the roller H, as shown. This second wiper, J, may be attached to the interior of the box part of the case by any suitable means.

Arranged longitudinally within the box or body part A is a roller, B, which carries on IOO sheet being entered down within alongitudinal recess, d, in the roller and engaging with pins or pointed teeth 8 therein, which project obliquely in a downward direction from one wall of the recess d toward the other wall, whereby a firm hold is obtained for the paper without exposing it to being punctured otherwise than at its end through a single thickness, thus preventing the marring of the sheet or roll of sensitive paper.

The roller B, which may be wood or other suitable material, is protected at its ends by ferrules D, which are constructed with outer tubular central necks or externally circular sockets, 6, whereby saidferrules are alsomade to form journals for the roller, and by suitably shaping the interior of said sockets provision is made for introducing a key, E, to engage with the roller for the purpose of rotating it to roll or take up the paper, either when first charging the case or in the event of more paper being drawn out than is necessary at any one time. By arranging these ferrule-journals at both ends of the roller carrying the paper, opportunity is afforded for turning said roller by its key from either end of the case. Said ferrule-journals have their bearings in the plates b b, which thus form journal-boxes, as well as end covers to the case, constructed to exclude-light from entering at the end joints of the case. i

To prevent the too free turning of the roller B, or, in other words, to throw a resistance upon it by friction, which will retard its run and so facilitate the drawing out of the sensitive paper from the case in measured or desired quantities, cupped spring-washers G are introduced at the ends of said roller, between it and the ends of the case, thereby producing an endwise pressure against the roller. The roller H also serves as a guide for the tissue or paper as it is drawn over said roller from the interior of the case by draft on its outer end from the side of the case having the opening L, to supply or measure off any desired amount of paper, which isthen torn oft immediately in front of or close up to the guideroller H, thus leaving the remainder of the paper under the close and light-tight cover of the case. Furthermore, the two wipers I J are arranged so that the one wiper acts on the friction or guide roller H throughout its length to keep it clean or free from dust, and the other wiper acts on the tissue or paper itself for a similar purpose, thereby preventing injury to the sensitized surface of the paper by dust collecting on it. This is in addition to the hereinbefore described other and main function of said wipers-namely, of excluding light from the interior of the case,and which, if admitted, would destroy the usefulness of the tissue or paper for photographic purposes.

To more effectually exclude the light from the interior of the case when closed, the lid has not only a close fit'at its ends under cover of the plates b b, but a tongue-and-groove fit,

as at g, with the box part of the case along or in line with the hinges, and the case is held close shut and friction thrown upon the wipers I J, roller H, and tissue 0, passing over said roller, by spring-buttons K, applied to the back of the lid A and box part A. By suitably turning said, buttons, however, as shown by dotted lines in Fig. 4, the case may readily be opened when required to introduce a fresh sheet or roll of tissue, or as other circumstances may render necessary.

The case, as thus described, for storing photographic sensitive paper may be carried in the pocket or elsewhere without risk of exposing said paper to light or dust, and the paper may be torn off for use in lengths of any desired size without affecting or exposing the remainder, and the case will be found much more convenient in this and other respects than a portfolio carrying between its leaves detached lengths or pieces of photographic sensitive paper.

Having thus described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. As an improved article of manufacture, a light-tight case for the storage and delivery of continuous rolls of photographic sensitive paper or tissue, made substantially as described, the same consisting of a case adapted to contain a continuous roll of the sensitive material, and provided with a longitudinal slot having one or more flexible lips through which portions of the roll of sensitive tissue may be withdrawn as desired, while access of light to the tissue remaining within the case is prevented, all as set forth. 1

2. In a case for storing photographic sensitive paper, the combination, with a lighttight box having a light-tight passage-wayfor the movement of the paper sheet into or out of the box, of a roller operated from the exterior of the box for drawing in and out the paper, as set forth.

3. In a case for storing photographic sensitive paper, the combination, with the box having a passage-way for the movement of the paper sheet in and out of it, of a rollerv essentially as and for the purposes herein set forth.
