HUMIDOB FOB FILMS.
Application led December 12, 1,927. Serial No. 239,455.
It is known that motion picture films should be kept moist, and for this purpose the present invention provides a humidor consisting of a case with a pad or piece of absorbf ent material held therein, the object of the invention being to provide improved means for holding the pad in place, so that it can be readily renewed or removed when desired.
Said means comprising a screen which in one form has tongues at the edge which by turn-v ing the screen will slide or snap under clips struck up from the metal of the case, at the edge of a depression at which the pad is received. In another form the screen is held in place by a ring which is fastened in much the same way.
The invention is illustrated in the accompanying drawings in which Fig. 1 is a cross section of the case or container. Fig. 2 is an inside plan view of the bottom part thereof. Fig. 3 is a similar view ofa modification. Fig. 4 is an enlarged detail of the fastening device.
In the drawings 6 indicates the bottom part such as is used for storing motion picture films. 7 is the removable top or cover part. The bottom part 6 has a central depression 8 formed or stamped therein to receive the pad 9 of absorbent material which Will be saturated With water or other liquid used to keep the film moist. This pad is retained by a screen 10 which may be made of perforated metal, and the edge of this screen is provided with a plurality of tongues 11 projecting outwardly therefrom and adapted to engage under clips 12 formed by slotting and upsettting the bottom of the case at the edge of the depression 8. These clips or slots are open at one end and are so located as to match the tongues 11 in number and position. Preferably each clip has a rib 13 formed or bent therein toengage in a corresponding groove or channel 14 pressed in each'tongue 11.
of an ordinary tin or sheet metal container' In the modified form shown in Fig. 3 the 45 screen 10*JL is made circular, to fit the depression, and is held in place by a separate ring 15 which fits thereover and is provided with tongues 11 similar to the form above described and for the same purpose.
In assembling the parts shown in Figs. 1 and 2 the pad 9 is placed in the depression and the screen 10 is placed thereon, and then by turning the screen the tongues 711 slip through the slots until they engage under the clips 12, the ribs 13 snapping into the grooves 14 to hold the screen against accidental displacement. In the form shown in Fig. 3 the ring 15 is placed upon the screen and turned in the same manner to engage the tongues under the clips.- Obviously the screen or ring, as the case may be, may be turned back by special pressure to disengage the tongues and permit removal of the pad for any purpose de; sired.
The parts can be cheaply stamped out of sheet metal, and quickly assembled for the purpose described. A.The moisture in the pad will keep the film moist .when a reel thereof is placed in the container for packing or 7o shipping.
I claim: Y
1. A container having a recess in one wall thereof and slots at the edge of said recess, a pad in the recess,and a screen upon the pad 75 having tongues at its edge engageable in said slots by a turning movement of the screen.
2. A container for reels or the like, made of Sheet metal and provided with a recess in one wall thereof, said wall being slotted and so struck up at the edge of said recess to form clips, a pad in the recess, and a screen upon the pad, having tongues projecting at its outer edge engageable under said clips by turning movement of the screen.
In testimony whereof, I atiix my signature.
