FIBEPROOF FILM-BOX.

Application filed August 27, 1914.

To all whom it may concern:

Be it known that we, EDWARD A. RUPERT and JOHN T. DRUM, citizens of the United States, residing at Aberdeen, in the county of Chehalis, btate of Washington, have in vented a new and useful Fireproof F ilm- Box, ofwhich the following is a specification.

The present invention relates to improvements in fire proof film boxes, one object of the invention, being the provision of a box which is adapted to retain and hold the films in a safe place while in the booth and while the motion picture machine is'being operated, the same having a plurality of compartmentsto permit of the retention therewithin ofa plurality of reels of film, and being provided with a closure for each receptacle for the reel, and which necessitates the absolute closing thereof before the reel of film is properly'held therewithin, and which when the closure is removed, will permit of the slight projection of the reel to allow of the easy removal thereof.

A further object of the present invention, is the provision of a film box or casing, in

which all of the walls are double walls and incased with a fire resisting material as sheet asbestos, and providing a means whereby the reels of film are protected when incased therein against accidental ignition or explosion, due to the contact o'f flame therewith.

A still further object of the present invention, is the provision of a novel construction of closure, that must be entirely closed before the same is locked against the normal tendency to open, thus making it necessary for the operator to move the door or closure to its full closed position.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

In the drawings Figure 1 is a perspective view of the complete box or casing, one of the doors being opened and showing the position of the reel of film. Fig. 2 1s a verti- Specification of Letters Patent.

cal sectional view taken through one compartment of the box or casing. Fig. 3 is a transverse section taken through the forward portion of the casing, showing both doors closedl Fig. 4 is a vertical transverse section through a portion of one of the closures or doors showing the method of fire proofing the same and holding the walls thereof spaced. Fig. 5 is a cross section taken through one edge thereof. Fig. 6 is a cross section taken through one of the walls of the casing. Fig. 7 is an enlarged detail view showing the locking bolt for holding the closure or door in closed position. Figs. 8 and 9 are detail views of the containers for preventing the walls or partitions from collapsing.

Referring to the drawings, the numeral 1 designates the casing or box, which is made rectangular in form and is adapted to assume the position as shown in Fig. 1. The central partitional wall 2 divides the present box or casing into the compartments 3 and 4 thus permitting the insertion or removal therefrom of two reels R of film, one reel to each compartment.

Each outside wall 5 is constructed similarly and includes the two sheets of metal 6 and 7 which are held spaced at their forward ends by means of the strips 8 of iron, the two sheets of asbestos 9 being secured by rivets 9', as shown in Fig. 6, to the inner faces of the respective sheets 6 and 7, while the corrugated rings 14: are seated therebetween, and being made of metal form a stifi retainer to hold the sheets 6 and 7 spaced and thus prevent the collapsing ofthe sheets 6 and 7. .The partition 2 is constructed similarly, being composed of the two sheets 11 and 12 of metal spaced at their forward ends by means of the strip 12, the inner walls being lined by the sheets 13 of asbestos, while the corrugated retaining ring 14: is interposed as shown in Figs. 2 and 3, to properly hold the sheets 11 and 12 against collapsing. I

The bottom 15 of the respective compartments 3 and 4, as illustrated in Fig. 2, is inclined at its rear portion, so that the reel R will have a normal tendency to roll toward the open end of the compartment or chamber, and thus have its periphery projected thereout as illustrated at the left in Fig. 1, so that the operator may readily remove the reel after the closure or door 21 has been moved from the closed position at the right in Fig. 1 to the open position as cushion for the edge of the metal disks of the reel 'R, thus preventing injury thereto. Sealing the forward open end of the casing 1, is a metal spring 17, which is composed of flanged strips 19 and 20, while the screws 18 secure the same in place. The lower end of the frame is opened as at 22', so that the respective slides or closures 21 may be moved therewithin and project therebelow, as shown'in Figs. 1 and 2. A projecting lip 23 is provided at the lower edge of the frame 17. Each door or slide 21, as shown is pro-' vided with the operating knob 22, which is of the type that is readily secured in place and which acts as a limiting means for the slide when it is in its lowermost or open' position. The lower portion ofthe slide is bent to form a right angled arm or plate 24, which thus forins a closurewith the bottom of the box when the door or slide 21 is in closed position. Each door or slide 21 is composed of a single sheet of metal and is compressed to provide the casing or cham- 3 her 25, and the oppositely disposed guiding flanges 26, sheets of asbestos 27 interlining the same, while the segmental corrugated retaining rings 28 are disposed within the chamber 25 to prevent the collapse ofthe walls thereof.

' In order to provide a means for locking the respective doors or slides 21 when elevated to their extreme upward positions, and only atsuchpoint, the slides normally fallin when released, so as to necessitate the agsolute closing or positioning of the same by the operator after the reel has been placed therewithin, there is provided upon the rear of each slide near the lower endthereof, a depression 29, which is adapted to receive the locking bolt 30, which is disposed for sliding movement within the tubular casing 31, the spring 32 normally holding the same extended into the recess or depression, this structure being clearly shown in Figs. 2 and 7. By reason of the peculiarshape of the bottom of the compartment, the reel R when inserted or resting therein, will assume the position as shown at the left in Fig. 1, in dotted lines as illustrated in Fig. 2, the closure of the door engaging the lower portion of the reel and moving the same to assume the dash line position in Fig. 1, the bolts 30 engaging the depression 29 and thus locking the closure or door in the elevated or closed position with the reel properly seated within the compartment. Upon the release and lowering of the door, the reel will roll forward due to gravity and againbeing in ready position for removal without necessity of entailing any extra work upon the operator.

What is claimed is:

1. A rectangular box or receptacle open at one end, the bottom of the receptacle being inclined from the rear toward the front, and a vertically slidable closure for the open end thereof adapted when open to have the upper portion thereof projected above the bottom to act as a stop to prevent the contents from falling out.

2. A box or receptacle of the character described, having hollow surrounding walls open at one end, the bottom of the receptacle being inclined from the rear toward the front, anda vertically slidable closure for the open end thereof, adapted when open to have the upper portion thereof projected above the bottom to act as a stop to prevent the contents from falling out.

3. A box or receptacle of the character described, having hollow surrounding walls open atone end, thebottom of the receptacle being inclined from the rear toward the front, a vertically slidable closure for the open end thereof adapted when open to have the upper portion thereof projected above the'bottom to act as a stop to prevent the contents from falling out, and a cooperative locking. means carried by the bottom and door to lock the door in closed position and to permit free sliding movement thereof to open position.

4. A box or receptacle of the character described, including hollow rear, top and side wall, a hollow partition dividing the box into a plurality of verticalcompartments, the compartmentsbeing open at the front, a frame fitting over one end of the box or receptacle and providing it with slots open at the bottom edge, and a plurality of slidable doors, one to each com artment mounted in the frame, each door ein adapted to open sufliciently to permit of t e introduction of a reel and to prevent of the acci dental displacement thereof when the door is open.

5. A box or receptacle of the character described, including hollow rear, top and side walls, a hollow partition dividing the box into a plurality of vertical compartments, the compartments being open at the front, a frame fitting over one end of the box or receptacle and providing it with slots open at the bottom edge, the bottom of each compartment being inclined from the rear toward the front to cause a film reel to roll toward the open end of the compartment, and a plurality of slidable doors, one to each compartment mounted in the frame and adjacent the 0 on end of the compartment, each of sai doors constituting an abutment to prevent the reel from leaving the compartment and permitting a portion removal.

6. A film box, the rear, side and bottom walls of which are hollow, a partition wall dividing the same into a plurality of compartments, the bottom of each compartment being inclined from the rear toward the front, a plurality of vertically slidable doors, one to each compartment, a knob carried by each door and forming a limiting means to limit the opening thereof, and so as to project a portion thereof above the bottom to act as a stop to preventthe accidental emptying of the compartment, and

a lock for engaging the door to hold the 5 same in closed position, said lock permitting the easy closing and opening of the door and preventing it from being stopped at any intermediate point.

In testimony that we claim the foregoing 20 as our own, We have hereto aifixed our signatures in the presence of two witnesses.
