Application filed February 10,1927. Serial No. 167,271.

posing the material still contained in thepack. A further object of the invention is to provide a pack for sensitized material which will permit a roll of such material to be shipped to the user in a light locked conditior, the inclosing casing for the sensitized material being so constructed that it may be utilized for supporting the sensitized material within the photographic apparatus.

To these and other ends, the invention con sists of certain parts and combination of.

parts all of which will be hereinafter dc scribed; the novel features being pointed out in the appended claim.

In the drawings:

Fig. 1 is a perspective view of a sensitized material pack constructed in accordance with this invention;

26 Fig. 2 is a longitudinal section through the pack;

Fig. 3 is a transverse section through the pack;

Fig. 4 is a view of one end of the pack; and

Figs. 5, 6, 7 and 8 are fragmentary views of different forms of the light locked delivery opening of the pack.

In the illustrated embodiment of the invention 1 indicates an opened ended tube made '3 in this instance of cardboard and having its ends closed by metallic heads 2 which have depressed centers providing cylindrical portions 3 fitted into the end of the tube and outwardly deflected portions 1 abutting the ends of the '40 tube, the latter having each laterally turned plugs being fitted within the. opposite ends of the roll 8 of sensitized sheet material. Each plug, in this instance, is of cup formation and 60 has its bottom perforated and formed with an inwardly projecting flange 9 which cooperates with a bearing 6.

The tubular wall of the pack has a light locked discharge or delivery opening or slot through which the sensitized material is drawn. This light lock may be of any suitable construction.

In the embodiment shown in Fig. 3, the slot 10 has one wall covered at ll with flannel. A wooden bar 12 covered ,with flannel 13 is fastened at 14 to the opposite side of the slot 10. The container being made of cardboard provldes to a certain extent a resilient support for the bar 12 andholds the latter with yielding pressure toward the flannel 11 on the opposite side of the .opening. The sensitized sheet from the roll 8 passes between the flannel 11 and thebar 13. In the embodiment shown in Fig. 5, the wall of the pack 1 has a small slot and opposite walls of this slot are covered with flannel 11". This slot instead of being radial to the axis of the container is an angle to the radius. In the embodiment shown in Fig. 6, the slot is radial to the axis of the container or pack 1 and opposite walls are extended inwardly at 13". Flannel coverings 11 extend over both walls. In Fig. 7 the container 1 is made of laminated card-' board and is so formed that the laminations overlap on the two sidesof the slot, as shown in Fig. 7 providing a slot with zig zag walls. In the embodiment shown in Fig. 8 the slot 10 has one wall 13 overlapping the other wall, both walls being covered with flannel at 11.

From the foregoing it will be seen that there has been provided a pack for sensitized material in which the sensitized material is in the form of a roll enclosed in a casing or enclosed receptacle and adapted to turn therein, the sensitized material leading from the roll through a slot in the casing or enclosure and light locking means being arranged at the slot and cooperating withopposite faces of the sensitized sheet to prevent the entrance of light into the casing while at the same time permitting the sensitized sheet to withdrawn from the casing. It wilt be derstood =0f course, that in the first instance a portion of the sensitized sheet will be ex.

tended through the slot so that the sheet may be unrolled Without openin the casing.

It will be noted that in Tigs. 3 and 5 of the drawings, the ,opening formed by the light slot is in the line with a tangent of a circle concentric with the axis of turning of'a roll and situated substantially midway between said axis of turning and the inner periphery of the enclosure. This arrangement of the slot is important as it permits the sensitized material to be withdrawn from the roll without producing any material bending of the sensitized material. full or complete, there is a slight bending of the film in one direction as the roll un- Winds. This bending decreases until a time is reached when the roll is about half unwound and all bending ceases. Thereafter, a slight bending of the sensitized material in the other direction takes place. At all times there are, however, no short bends in the sensitized material. It will also be noted that the roll supporting means is inaccessible from the exterior of the container. This makes-it impossible to refill the container or enclosure through the discharge slot.

What I claim as my invention and desire to secure by Letters Patent is:

A sensitized material pack comprising an open ended tube, provided with a light locked slot extending longitudinally thereof, permanent heads closing the opposite ends of the tube, bearings projecting inwardly from the head and inaccessible from the exteriorf of the pack, and a roll of sensitized material having lu s in opposite ends thereof turning on t e earin s of the head. 7
