Application filed October 19, 1929. Serial No. 400,793.

The object of my invention is to rovide a cabinet of this kindwhich will hol fifteen limited, and yet the films must be accessible and easil and quickly inserted or withdrawn. urthermore, provision must be made so that should spontaneous combustion occur in a film,.no further damage will be done and no other film will be ignited, so that the cabinet is safe as well as compact. A further object is to make a'cabinet which may be made in sections, one section to be put on top of another, until the desired capacity is obtained. These and other objects are'accomplished by my invention, one embodiment of which is hereinafter more particularlysetforth.

For a more detailed description of my invention, reference is to be had to the accom panying drawings, forminga part hereof, in which;

Figure 1 is a front elevation of m improved cabinet, three sections and a topbeing shown; Figure 2 is a side elevation of the same;

Figure 3 is a s ctional View taken on the b line 33 of Figure 1, looking in the direction of the arrows;

Figure 4 is a sectional view taken on the line H of Figure 3, looking in the direction of the arrows;

Figure 5 is an enlarged longitudinal section through a compartment having a film;

Figure 6 is a sectional view taken on the line 66 of Figure 5 looking in the direction of the arrows; b

Figure 7 shows certain parts detached so as to reveal detailsof construction.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In Figures 1 and 2 are shown sections 1, 2 and 3, and a top 4. As the sections 1, 2 and '3. are identical, a description of one will answer for all. Each section has an exterior wall 5 which extends on three sides and has an external sheet 6 and an internal sheet 7,

section throughout the remainder of its united at the front by a suitable joint 8 which may be of any suitable form but which are preferably made as shown in Figure 3, with interlocking seams. There is no top or bottom to these walls 5 as one section stands on the other except that the lowest section has an extra bottom which. is 'fireproof, under normal conditions, and the top section is 0017- ered by the top 4. It is important that the air space in the partition 5 between the sheets 6 and 7 should extend from top to bottom for a purpose that will appear below. Each section has at its front .a number of door frames 9 whichare rectangular in outline and extend from top to bottom, and each door frame is adapted to be closed by a hinged door 10, which is slidably mounted on a pivot 11, which may be circular in cross section at its top and bottom, and square in its cross length. 'Eachdoor is also provided with a handle 12. Each door is composed of two sheets, 13 and 14, secured together in any suitable manner and preferably in the way indicated, and the sheet 14'is bent so that the top is tapered where it fits against its frame 9, as indicated in Figure 3. There is also in the door frame a projection 15 which is in front of the door and the door is lifted over the same when opened or closed, this being permitted because the door slides on the pivot 11 and the frame 9 is a little higher than the door, although only slightly so. However, the difi'erence is sufiicient to enable the projection 15 to be cleared. This simple construction does away with the need of all latches and catches, and well holds the door closed with a tight joint which is very important as will appear below.

Each door 10 is opposite acell 16 extending from front to rear, and reaching the rear wall 5 of each section. Each cell 16 is composed of an inner casing 17 of asbestos so that each cell is completely lined with asbestos on all sides except the front, and the door 10 may be lined with asbestos, if desired. Exterior to this asbestos casing 17 is a sheet 18 of metal which securely reenforces and holds the asbestos The top sheet 18 is flanged upwardly at19 to fit snug against the inner sheet 7 of the wall 5 and it is preferably held in position by means of a cap 20,- which extends over this sheet 7 as well as over the flange 19. At the rear of each cell 16 and near the door of the same, there is an opening 21 which runs to a space between the rear wall of the cell and the partition 7 and at the top of partition 7 is an other 0 ening 22 which runsinto a space surroun ed by a bent plate 23 which is secured to the exterior of this partition and between it and the plate 8 and this partition is preferably riveted in place so as to be secured at all times. The purpose of this is to let the products of combustion, should a film in the cell get on fire, rush out through the openings 21 and 22 and through the hollow of the plate 23 and thereby escape between the partitions 7 and 8 to the top a from where these products may be drained through an opening 24 at the top of the cover 4: and be taken from the booth and building so that no poisonous fumes will be confine in a small space occupied by human beings, as such fumes are very dan erous. The lon and tortuous passage for t ese fumes, whi c is constantly upward, will prevent any in-,

grass of flames to a cell where there 15 no combustion, so that the film in one cell may get on fire without in any way endang'erin or disturbing the films in other cells. t wil be noted that the cells are each separated by lar e air spaces 25.

it the bottom of each cell 16 is a floor 26 which is secured to the side and rear walls of the cell in any-suitable manner and also to the front, as by riveting, and at the front this floor is provided with two parallel slots 27 (see Figure 7) which cause a tongue to be formed between them and on this tongue and in these slots is placed a loop- 28 which is pivotally connected to an ejector 29 in any suitable manner so that the front of this ejector is pivoted and the rear of it may rise or fall according to the opening of the door as will now appear. This ejector is well weighted at 30 atits rear end so that it will fall by gravit or else be lifted by mechanism now to described. The under surface of this ejector rests against a bent-lever 31 pivoted at 32, just below the lower surface of the floor 26 and to this floor as shown in Figure 5, and the lower end of this bent lever 31 is pivotally connected to a link 33 that runs to a crank 34: which is fixed to the pivot 11 so that when the door 10 is opened, the link 33 is drawn to the front, as shown in Figure 6, and the ejector 29 israised as shown in dotted lines in Figure 5, and when the door is closed, this ejector is lowered so that the film roll 35 rests in place with no inclination to roll against the door 10. When thedooris opened, the ejector is raised at its rear and the film rolls out. When the film is inserted, it rolls from the hand of the operator on to the ejector and before it has time to reverse its movement, the door is closed and there is no-tendency of the roll to come against the door.

In view of the foregoing, the operation of my invention will be readil understood. Under normal conditions, the s are stored as above described, and if one of them gets into a state of combustion from internal or other causes, it has to burn in an atmosphere where there is very little air, and the products of combustion will go out through the vents above described, and there is no chance of one film setting another on fire. 'This is most important, as it is diificult to make a practical cabinet which can withstand the efiects or all films being in a state of coinbustion at once. Under normal circum stances, there is no combustion, and each film is inserted and removed with facility as above described, and very little space is requlred for the functioning of the doors 10, as they are pivoted on the long and not the short side. Furthermore, as many sections may be used as required, and each section is interchangeable with the other, so that any may be replaced or put above or below another, as desired. It will be noted that the sheets 7 and 8 are slightly offset at their u per edges so as to permit one section to fitted on another, as above set forth.

While I have shown and described one embodiment of my invention, it is obvious that it-is not restricted thereto, but that it is broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is:

'1. cabinet section having a number of cells in wh ch films may be stored, constantly open means for removing the products of combustion from each cell, a vertical door lunged on itsvertical side for closing each cell and means oonnectedwith each door for e ecting a film from its cell so that it may rollinto thehands of a person opening the door.

2. A cabinet-for storing films comprising aplurahty of sections, each of which is prov1 ed with a plurality of vertical, rectangular cells with air spaces between them, an asbestos linin open flue bac of each cell or rmittingthe escape of products of combustion in that cell, means connected with each door for for each cell a constantly ejecting a film from its cell so that it may roll them, door frames at the front of this section, a series of cells connecting the door frames with the rear wall, it door for eachcell, each door being slidebly mounted one pivot and a. lug in a door frame over which the door may pass so that it will stay in place when closed. I

,4. A. section of a cabinet for films, which is composed of two bent sheets separated from each other, and means for holding them in fixed relation for forming the walls of three sides of the cabinet with e flue between them, openings from each cell to this space,

door frames at the front of this section end my hand this secured to said sheets, acell connected to each door frame and a hinged door for closing each cell. i

In testimony whereof, I have hereunto set 16th day of October, 1929. WILLIAM GLUCKMAN.
