A ril 29, 1952 c. F. GALLOWAY DISPENSER FOR LIGHT-SENSITIZED SHEETS Filed Nov. 25, 1949 Z'mnenfor 6%.2455 5 6441mm Y Gfiomeg Patented Apr. 29, 1952 DISPENSER FOR LIGHT-SENSITIZED SHEETS Charles FrGalloway, Los Angeles, Calif. Application November 25, 1949, Serial o. 129,427 V The present invention relates to a dispenser of the type adapted to hold and progressively disp'en'se single sheets of sensitized paper.

The present invention has for an object a device wherein sensitized paper in sheet-form may be dispensed from the said container, a sheet at a time, with assurance that light will not enter the container and spoil other sensitized sheets therein during a dispensing operation.

A further object is the provision of a dispenser, which may be quickly loaded with sensitized paper.

Further objects include the provision of a dispenser which is inexpensive in cost of manufacture, sightly in appearance, fool-proof in operation, and generally superior to devices now known to the inventor.

In th drawing: I y I Figure 1 is 'a perspective view of the dispenser,

Figure2 is a top plan view of the container,

Figure 3 is a bottom plan view of the cover for the container, and

Figure 4 is a transverse sectional view on the line 4-4 of Figure 1.

Referring now with particularity to the drawing, the improved dispenser includes a container I provided with a cover 2. The container l is of the form shown in cross-section in Figure 4 and has a front wall 3, rear wall 4, and end walls 5 and 6 with the base I of said container provided with an elongated transversely arcuate slot 8 adjacent the front wall 3 of said container and with an inclined wall or table portion 9 extending from the rear wall to the arcuate groove 8. As shown, the end Walls 5 and B are substantially of uniform height. The rear wall 4 and end walls 5 and 5 are formed with an elongated external groove Ill. A portion of said end walls 5 and 6 and front Wall 3 is grooved at I! and 12. In addition, the top edge of the front wall 3 is longitudinally recessed between the end walls 5 and 6, as shown at I3.

The cover 2 is provided with a curved top wall l4, a front wall l5 and two end walls i6 and IT. The construction is such that the end walls are of lesser depth than the depth of the front wall and do not entirely bound the curved top wall. In other words, the curved top wall rearwardly of the front wall portion extends beyond the end walls as shown in the figures. This extension or skirting; here designated as ill for the curved top wall, overlaps the rear edge l9 of the end walls 5 and 5, and said portion I8 is provided on its inner surface with a longitudinally extending bead adapted to be received within the longitudinal groove IU of the container. The front wall of 2 Claims. (Cl'. 312-54) the cover has a skirting 2| provided with a longitudinally extending bead 22 which fits between and within the grooves l l and I2. The construction is such that the skirting I8 of the cover flexes so as-to allow the beads 20 and 22 to be received within the grooves H], H and I2 of the container and thereby hold the cover securely, but detachably, to the container. As shown in the drawing and particularly in Figure 1, there is a close fit engagement between the ends of the cover and the ends of the container. The front wall l5 of the cover 2 is thickened with respect to the remaining portion of the cover to give stability to the structure and likewise to accommodate other elements of the invention. As shown in Figure 4, the bead portion 22 of'the cover'is spaced by a groove 23 from a portion 24. Portion 24 carries a pair of seals 25 and 28. Seal 25 is secured to a flattened edge of portion 24 while seal 26 is carried at an angleto seal 25.

Adapted to be longitudinally positioned for rotation within the. container and within the confines of the groove 8 is a roller 21. This roller is mounted on end trunnions fitted within the ends of the container and one trunnion. externally carries a knob 28 whereby the roller may be manually turned. As shown, the periphery of this roller is adjacent the seal 25 and the lower edge of seal 26 engages the roller. With the cover in position on the container, a slot is formed as between the bead 2| and the recess l3. The seals 25 and 26 are spaced rearwardly of the said discharge slot so that when the roller is turned, a sheet may be fed by the roller between said seals and outwardly through said slot.

As illustrated in Figure 4, the table 9 is at an angle to the base. A stack of sensitized paper rests partly upon the table 9 and partly upon the roller 21, rearwardly of the seals 25 and 26. The lowermost sheet of the stack is at all times in pressure engagement with the periphery of the roller, there being a pair of spring fingers 28 and 29 secured at one of their ends to the wall 4 of the container, while the opposite ends are secured to an elongated pad 3|. The pad 3| is adapted to engage the outermost sheet of the said stack of sensitized paper as shown in Figure 4 at 32. Both fingers are bowed as illustrated in Figure 4.

The operation, uses and advantages of the invention just described are as follows:

The container is loaded with a stack of lightsensitized paper in a dark room and the cover then secured to the container. This cover by having a resilient skirt l8 will retain its position on the container without shifting and release thereof from the container requires some exertion on the part of the operator to flex the skirt.

When a stack of the light-sensitized sheets is to be dispensed one at a time, the lowermost sheet will engage the friction roller 21, and as the roller is turned, the lowermost sheet will be fed between the light seals 25 and 26 and outwardly through the. discharge slot inthe front wall of the container. As shown, the lowermost sheet is forced to bend in passing over the periphery of the roller between the light seals 25 and 26 and likewise to bend slightly in being; directed through the discharge slot. We observe that the; seal 26 is rearwardly of the discharge slot and has elongated edge engaging the periphery of theroller. Such a seal forms an obstruction. to the passage of light within the container. When the lowermost sheet of light-sensitized paper is moved by the roller, a seal 26 will flex and engage the-top surface: of; saidv sheet and still obstruct any: light.- passage within the container. This constructionprovides a convenient form of li trap;

It is to be observed that the stack of lightsensitized sheets. has a concave appearance as indicated in Figure 4. The spring fingers tend to depress the. stack so that the lowermost. sheet of saidstacl will at all times be in; frictional engagement withthe roller. The table 9 is at an angle and asthe; stack is pressed downwardly by the said? fingers, such as may occur when the stack is reduced as to. thickness; the table. will nevertheless support the stack; and hold the lowermost. sheet in frictional engagement with the. roller. This is an, important feature of the present construction.
