apparatus.

At the present time many business institutions duplicate many records, films and the like through photographic means. film of the duplicated record is in a hazardproof vault for protecting the film and quently occupy valuable space in the vault.

In many institutions, a film for photographing purposes may remain in the machine for a considerable length of time. The film remains in the machine until it is fully exposed. This may require anywhere from a few days to a month. In addition, an important prises the photographs of documents taken on the current day and those taken the previous two or three days. Many of such items, especially in banking institutions, are transmitted through the mails. Should the mail miscarry or the items become lost or destroyed, such a loss would result in considerable trouble event that if, on the current rying the record of the lost item were destroyed by fire or otherwise lost. It is, therefore, important to provide ample protection for the film as well as to provide ready accessibility thereto. Present types of photographic devices are difficult to handle since the entire machine must be placed in the vault to handle each business day.

Accordingly, an object of my invention is to provide a detachable film compartment which night, the film careasy to handle, in addition to requiring a relatively small amount of space in the vault.

In the accompanying drawing;

Figure 1 is a front elevational view of a photographic copying and projection machine of a conventional type wherein my sectional feature is incorporated;

Figure 2 is a face view illustrating the film compartment detached from the remaining portion of the machine; and

Figure 3 is a sectional perspective view of a track constituting a connection between the detachable film compartment and the remainder of the machine.

In the embodiment selected for illustration, I make use of a machine along the general lines of that illustrated in Patent No. 2,18iLGG7, wherein a cabinet It is employed and wherein a housing I 2 mounted on the top of the cabinet IS contains a camera compartment on the side 14 and a projection compartment on the side E6. The housing I2 is severed vertically along the horizontally along the line 28 up to the severance line 22 extending a short distance downwardly of the cabinet iii. The mechanism is housed in the compartment 24. When the housing I2 is severed vertically along the line It the circular indicator 38 will remain fixed in compartment 24 where the mechanism is housed. To compensate for the projection f the indicator 38 beyond the contours of the side M the side It is provided with a semi-circular recess 43. Since the housing l2 must be light proof this structure is essential in the assembly thereof.

Figure 3 illustrates a front wall portion 26 of the cabinet which extends beneath the mechanism compartment 24. The lower edge of the wall 23 is provided with a flange 28 slidably receivable in a channel 30 formed on the cabinet wall 32. The housing I2 and the line of severance 22 extend the full length of the machine so that both the front and rear wall of the housing I2 as Well as the cabinet ID are fashioned in the same manner. Thus the front and rear walls 32 of the cabinet ill will each have a channel 30, which is also true of the front and rear wall portions 26 with respect to the flange 28. Accordingly, the film compartment I4 together with the mechanism compartment 24 may be slidably detached from the projector compartment 16 and the greater portion of the cabinet structure. The flanges 28 and the channels 30 are in parallelism on the opposite ends of the machine so as to cause the detachable unit to slide easily into position. Thus the small detachable unit may be easily carried to and from the vault. Each of the wall sections 26 is provided with a handle 34.

The cabinet [0 is provided with an opening 36 in its front wall and the base structure of the cabinet constitutes a table or rest for documents being photographed or projected.

A ornamental stand 36 may be arranged across the side wall of the cabinet ll) adjacent the line of severance 22 so as to mask the otherwise unbalanced structural design caused by the sectional feature.

Without further elaboration, the foregoing will so fully illustrate my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A detachable and removable camera and film assembly for use with a projection device, comprising a supporting member on which the camera and film assembly and the projection device are normally disposed in juxtaposition and are moveable toward and away from each other, a semi-circular recess formed in the side wall of said projection device adapted to receive a circular projection on said assembly, handles on said assembly for moving said assembly into and out of operative position with said projection device, said projection device and said assembly being provided with open fronts, rear walls, top and side walls, said open fronts and said side walls and top adapted to coact to form a light proof assembly, the supporting member having spaced parallel channels and the camera and film assembly having base flanges slidably received therein to removably attach the camera and film assembly to the support.

2. A detachable and removable camera and film assembly for use with a projection device, comprising a supporting member having a top on which the camera and film assembly and the projection device are normally disposed in juxtaposition and are moveable toward and away from each other, the top having spaced parallel channels, the camera and film assembly having base flanges slidably received therein to removably attach the camera and filmassembly to the top, and the camera and film assembly and the projection device having vertical, opposed, parallel adjacent parts meeting in assembly on a vertical line, a semi-circular recess formed in one of the adjacent parts adapted to receive a circular projection formed on the other adjacent part, handles on said assembly for moving said part out of juxtaposition, said adjacent parts being formed with open front, rear, top, and side walls, and said adjacent parts thereby adapted to coact and meet on said vertical line to form a light proof assembly.

LESTER M. SEVEREID.
