UNITED STATES EDWARD P. FLYNN, OF ROCHESTER, NEW YORK, ASSIGN OR TO EASTMAN KODAK COM- PANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

SENSITIVE-MATERIAL UNIT.

Application filed March 8, 1923. Serial No. 623,588.

To all whom it may concern:

Be it known that I, EDWARD P. FLYNN, a citizen of the United States of America, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Sensitive-Material Units, of which the following is a full, clear, and exact specification.

This invention relates to a sensitized material unit adapted for use in a commercial copying camera. The sensitized material for use in such cameras generally consists of heavy, cumbersome rolls of paper to be. placed in the camera. Enough paper is drawn from this storage roll for a single exposure at a time and this is then severed and passed to developing and fixing baths.

Among the objects of my invention are to provide a unit which may be loaded into the camera, to provide means for centering the roll' of paper in such a unit prior to its being placed in the camera, to furnish automatic means for such centering and for closing the unit and to provide means whereby the paper remaining at any time may be removed in a protected container if it is desired to clean or repair the machine. Other objects will appear hereinafter.

Reference will now be made to the accompanying drawings, in which the same referencecharacters refer to the same parts throughout and in which- Fig. 1 is a perspective view of the box of my improved unit;

Fig. 2 is a section taken on line 11-11 of Fig. 1 the cover not being shown;

Fig. 3 is a section taken on line IIl-III of Fig. 1, the cover not being shown and the roll being indicated in dotted lines;

Fig. 4 shows the latch in detail;

Fig. 5 "is a perspective view of the roll of sensitive material;

Fig. 6 is a section through the unit as used in a copying camera, certain parts of which are indicated in dotted lines Fig. 7 is a fragmentary view, partly in section, illustrating the action when the box is being closed;

Fig. 8 is a fragmentary plan of one end of the box.

My new and improved unit comprises two essential elements, a box or container 1 and a package 2 containing the sensitized material. The box is of sheet metal and has a fixed bottom 3, fixed side walls 4 and 5, a fixed end wall 6 and a hinged end wall 7. In the fixed end wall 6 is an inwardly extending circular trunnion member 8 comprising an imperforate bottom 9, an inclined side wall 10 and an annular flange 11 by which it is secured in any suitable way in the rabbet 12 surrounding a central aperture 13 of the wall.. The wall? is hinged at 14, as shown, and has a trunnion member 15 identical instructure to that already described, the parts being similarly designated. The wall 7 carries near the upper ends of its side edges two angle brackets 16 to which-are pivoted at 17 the latch members 18 having inclined faces 19 and notches 20. On the inner faces of side walls 4 and 5 are pins 21, which are engaged by the latches in an obvious way when the hinged end is closed. The latches may be lifted to the inoperative position indicated in dotted .lines in Fig. 4 when the end is to be opened.

It is to be noted that side wall 4 is lower than wall5 for a purpose to be presently described. Finger rings 22 are provided on wall 4 for a purpose to be later mentioned. A removable cover 23 with flanges :24 that fit tightly around the sides of the box is also provided.

For the purposes of the present invention the package 2 of sensitive material is a cylinder with inwardly tapered axial openings in its end.'the particular structure of the cylinder being comparatively unimportant. As shown, it comprises a roll of sensitive paper 25. the outer end of which is tapered at 26 and secured bya'wrapper strip 27. End members comprise flanges 28 with reinforced edges 29 and central hubs 30. The

hubs are hollow and imperforate and taper inwardly and engage the inner convolutions of paper frictionally in a manner similar to that described in my Patent No. 1,377,154, granted May 3, 1921. They provide, end axial apertures with tapered walls for the package 2.

In practice, while the boxes may be furnished with the sensitive material, they will in general be supplied ,with the copying cameras for which they are adapted and the same box will be used with successive rolls of material. The cover is not used in the camera and is supplied so that if it is desired to remove theunit from the machine position shown, the several parts describing the arcs indicated. The inner end of the trunnion member will just engage the outer edge of the hub aperture, and as both hub and trunnion have correspondingly tapered side walls, further inward movement of the wall 7 will exert a caniming action between these two elei'ncnts to lift the end of the package 2 to a properly centered position in the box. The latches will automatically operate to hold the wall in its final position.

The unit comprising the box and the roll is then ready for insertion in the copying camera. The details of such a camera are not shown, as they constitute no part of the present invention. In Fig. 6, however, there are indicated certain elements showing how the unit is used. The camera includes a cabinet having a rear wall 31, a top wall 32 and a shelf 33 within which the unit is shoved from the left of Fig. 6, with the lower side wall 4: outwardly. The end of the paper is drawn out and a wall 34 having a guide roll 35 placed in the position shown. With the parts in these relative positions the paper is withdrawn and used as needed. No centering and positioning of the heavy roll in the camera is required, all of this being done inthe unit before its insertion in the compartment provided for it.

When the paper is exhausted, the wall 3i is removed and the unit withdrawn by the. finger rings 22. I

lit will thus be seen that T have provided means whereby the heaw y rolls of material are easily positioned and handled. 1 con template as within the scope of my invention all such modifications and equivalents as fall within the terms of the appended claims.

Having thus described my invention, what T claim as new and desire to secure by Letters Patent is:

l. Tn combination, a roll of sensitized material having end hubs with central apertures, and a box adapted to contain said roll and having a fixed end wall with a fixed trunnion engaging one end aperture, and having an opposite hinged wall, said hinged wall having a trunnion adapted to engage the opposite end aperture, the last named trunnion and the corresponding aperture being so shaped that when the wall is swung to closed position these parts will engage with a camming action and lift the roll to properly centered position in the box.

2. A. unit adapted to be placed in a commercial copying camera and comprising a cylindrical package of rolled sensitized material, and a box adapted to fit and contain said package, said box having a fixed end, said end and one end of the package having means cooperating 'to position and support the package, said box having a hinged end, said hinged end and the opposite end of the package having cooperating means for lifting said end of the package to properly centered position as the hinged end is moved to closed position, and for supporting the package in such properly centered position when it is in closed position.

3. A unit adapted to be placed in a commercial copying camera and comprising a cylindrical package of rolled sensitized sheet material, said package having inwardly tapering, axial apertures in its ends, and a box adapted to fit and contain said package, said box having one fixed end with a fixed trunnion adapted to fit one end aperture and an opposite pivoted end wall with a trunnion adapted to fit the other end aperture, said last named trunnion having inclined walls whereby when the hinged Wall is moved to closed position the walls of the trunnion and of the aperture will engage and cooperate to lift the spool to a properly centered position in said box.

4. A unit adapted to be placed in a commercial copying camera and comprising a cylindrical package of rolled sensitized sheet material, said package having inwardly tapering, axial apertures in itsends, and a box adapted to fit and contain said package, said box having one fixed end with a fixed trunnion adapted to fit one end aperture and an opposite pivoted end wall with a trunnion adapted to fit the other end aperture, said last named trunnion having inclinded walls whereby when the hinged wall is moved to closed position the walls of the trunnion and of the aperture will engage and cooperate to lift the spool to a properly centered position in said box, and means for automatically latching the hinged end wall in closed position.

5. A container for a roll of sensitive material and comprising a case with a fixed support at one end, an'inwardly directed trunnion carried by said fixed support and adapted to engage a suitable aperture in a roll of material, a support hinged at the other end of the case, an inwardly directed trunnion carried by said hinged support and having tapering sides, whereby it will tend to engage and lift a suitably apertured roll day of Feb. 1923.
