This invention relates to storage cabinets and vide a novel form of storage cabinet for picture reels. 7

Another object is to provide a novel form of automatic ejecting means whereby any selected reel can be instantaneously ejected] from a storage cabinet without disturbing adjacent reels.

A further object is to provide an improved structure of reel storage cabinet which is compact and specially designed for instantaneous identification and ejection of selected reels.

A feature of theinvention'relates to the novel form of selective ejecting mechanism whereby any one. or more of a series of stored reels or similar devices can be ejected by thesimple op eration of pressing a button, slide or the like.

A further feature relates to the novel organization, arrangement and relative location of parts which constitute a simpleimproved and compact automatic ejecting cabinet especially suitable for such devices as motion picture reels and the like.

Preferably, although not necessarily, the storage cabinet is fabricated from sheet metal and comprises a" box section I with a hinged front cover 2. The top wall 3 of the box is provided with a suitable carrying handle 4 which is rotatably held by means of an elongated channeled member 5 welded or otherwise fastened to the top 3. The region of top 3 adjacent the handle is recessed so as to accommodate the handle when it lies flat as shown in Fig. 2, the recess being sufiiciently deep so that neither the handle nor member 5 project'above the surfaceo'f top 3. In order to enable two or more such cabinets to be superposedin vertical alignment andwithout danger of relative slipping, the top 3 has four circularfrecesses" 6 adapted to receive the glides or feet I on the superposed cabinet. Preferably the feet 1 are of rubber, felt or other relatively soft material. The"front cover 2 is provided with an interlocked hand latch and key-lock shown in Fig. 4 and described in detail hereinbelow. A knob 1 is provided for releasing the latch when the key-lock is unlocked; Preferably, the front cover is provided on its outer face with a suitable receptacle 8 for a card index and on which is entered the number and other identification data of the respective reels of film which are to be stored in the cabinet.

As shown in Figs. 2, 3 and 4, the interior of the cabinet is divided into a series of stalls or compartments defined by thechannelled metal strips 9 having their fiat bases welded to the platform In which in turn iswelded to the bottom l l of the box. Preferably, the front corners of members 9 are'cutaway at an angle as shown. Members 9 not only provide stalls between their own parallel walls but also adjacent members 9 provide additional stalls. Each of the stalls is adapted to receive a circularcan orcontainer I2 with which is enclosed a picture reel or the like. Since these reel cans are well-known in the photographic art, a detailed description is.

not necessary beyond stating'that the dimensions of the box portion l are such that .the reels can be freely inserted and automatically ejected without obstruction. Preferably, the platform I0 is slightly inclined downwardly towards the rear wall [3 so that when the box is resting on a flat table or othersupport, the cans I Z are held by gravity against the ejector arms M (Fig. 3) thus preventing the reels rolling out of the box when the front cover is open.

A plurality of ejector arms I4, one for each of the reel stalls, are freely supported for independent and swingable movement on a circular bar mounted in the end walls N5 of a frame member ll'which extends along the length of therearwall l3 and hasits in-turned ends l8 fastened to the rear wall l3 by screws l9. The member I! has a series of narrow slits 20, one for each of the ejector arms [4 and in alignment with the upper end of the associated arm. Each arm I4 is swingably supported on bar l5 by means of a channeled member 2| welded thereto adjacent the upper end of the arm, the arms being spaced apart from each other to maintain them in alignment with the respective stalls by means of spacer collars 22. As shown more clearly in Fig. 3, the arms I4 are sufficiently long to extend downwardly into the associated stalls and preferably the arms l4 are of sheet metal each having a longitudinal strengthening rib 23.

Normally; i. e., when there is no reel can in a stall, the weight of the arms l4 causes them to assume a substantially vertical position represented by the dotted outline in Fig. 3. How-- ever, when a reel can is placed in its stall, it rolls towards the back of the box and its weight rotates the arm I 4 about bar [5' to the full line position shown in Fig, 3. The top wall 3 of the box at its front edge has a downwardly extending lip or flange 24 which is bent back inwardly of the box to form a horizontal lip 25. Attached to the portion 24 by screws 26 is an L-shaped metal strip 21 havingits vertical wall divided into a series of slots or windows 28, one for each of the ejector arms l4 and in alignment therewith. The strip 21 is fastened to flange 24 so that the horizontal lip 25 is slightly above the horizontal lip- 29 of member 21, thus providing a series of flat narrow guides 30 defined by

lips

25, 29 and the edges of the window 28, these guides being in alignment with the slits 20 in member I1.

For the purpose of operating the ejecting arms M, each is provided with a fiat metal slide 3| having its rear end extending through the associated slit 20 and its front end extending through the associated guide 30. In order to prevent dislodgment of the slides, each slide is provided at its front end with a notched portion 32 of approximately the same width as the windows 28 and the front end 33 of each slide is bent upwardly at an angle to provide a pushing surface as illustrated in Fig. 2. Assuming that each of the stalls has a reel can placed init, then the weight thereof holds the arms l4 so that their upper ends abut against the inner ends of the associated slides 3|, thus forcing the slidesto their forward position as shown in Figs. 3 and 5. When it is desired to eject a selected reel', the corresponding member 33 is pushed towards the rear of the box causing the associated arm 14 to rotate in a clockwise direction (as viewed in Fig. 3) and this motion of the arm [4 ejects the selected reel from its stall.

In order to simplify the selection of the appropriate reel, a suitable index strip 34 may be removably inserted in. a suitable channeled receptacle 35 fastened on the inner face of the front cover 2.

In order to prevent accidental opening of the front cover 2, it. is provided with an interlock mechanism consisting of a rotatable L-shaped latch 36 which is fastened to the shaft of knob 1. A coil spring 3'! has one end anchored in. an opening in the collar 38 welded to cover 2 and the other end fastened to the knob shaft. A lug 39. is struck-up from the member 38- to act as a stop for the latch 36, the spring 31 therefore normally maintains the latch 36 in its vertical position where it can engage the rear edge of lip 29 to prevent the cover 2 accidentally falling to its open position. When it is desired to lock the chest permanently, there is provided any suitable form of key-lock 40, the tongue 4| of which is adapted to be raised in interlocking relation with the notched end 42 of the latch 36 thus preventing the latch being turned to open the cover 2. By constructing the chest in the manner described above, the contents are rendered dust-proof and not only can individual reels be expeditiously selected and ejected but the device is very compact and of easy portability. Thus, while reference has been made herein to a picture reel, it will be obvious that the invention is equally applicable to the ejection of other devices such as phonograph records; and that the structure of the storage cabinet and ejecting means is not limited to any particular type of reel or record,

Various changes and modifications may be made in the particular embodiment disclosed without departing from the spirit and scope of the invention.

What we claim is:

1. A device for storing picture reels and the like, comprising. a cabinet for containing the reels and having, on its interior means to space the reels apart, slotted guide. means at the rear of said cabinet, corresponding slotted guide means at the front of the cabinet, the slots in both said guide means being in alignment, a plurality of operating members passing through the aligned slots in said guide means, a plurality of swingably supported levers each having one end adapted. to be engaged by a corresponding one of said operating members, the other end of each lever normally engaging a corresponding one of said reels whereby selective operation of one of said operating members causes the corresponding one of the reels to be ejected from the cabinet, said slotted guide means at the front of the cabinet comprising a downwardly extending lip on the front edge of the cabinet with an inwardly extending horizontal flange, and a notched member attached to said edge with the notches extending below said edge to define guides for said operating members.

2. A device for storing picture reels and the like, comprising a cabinet for containing the reels, means to support and separate the reels. within the cabinet, said means including a platform inclined downwardly towards thev rear of the cabinet so that said reels are held by gravity towards the rear of the cabinet, 3. cover hinged to the bottom wall of the cabinet, said platform terminating abruptly a substantial distance from said hinge so as to define therewith a stopping channel for reels ejected from the said supporting and separating means, and a plurality of ejecting levers, one for each reel and normally resting thereagainst and adapted to be selectively operated to eject a corresponding reel from the cabinet into the said channel.
