Nov. 20, 1951 c. o. OLSON ROTARY FILE 2 SHEETSSHEET 1 Filed May 7, 1947 IN V EN TOR.

Patented Nov. 20, 1951 ROTARY FILE Clarence 0. Olson, Chicago, Ill., assignor to Spin- Dex, Inc., Chicago, 111., a corporation of Illinois Application May 7, 1947, Serial No. 746,481

10 Claims. 1

This invention relates to rotary index files wherein a drum with file compartments spaced around its periphery is rotatable to bring any selected compartment into a position where access may be had to the contents thereof.

An object of the invention is to provide novel means to retain the contents of the various file compartments against displacement when such compartments are rotated away from the position wherein the contents thereof are customarily withdrawn or inserted.

A further object is to provide a rotary file of the aforesaid character in which are embodied various improvements to minimize wear and replacement of the movable parts and afford greater ease of operation.

Specifically, it is an object of this invention to provide a rotary card file having retaining devices for the contents of the file compartments which normally are urged inwardly to closed positions and which are so arranged that the retaining means for each file compartment is withdrawn positively by a cam or equivalent meanswhen the compartment is disposed in file-transfer position for extraction or insertion of its contents.

The above and various other objects, advantages and features of the invention will be apparent from the following specification when taken in connection with the accompanying drawings wherein a certain preferred embodiment is set forth for purposes of illustration.

In. the drawings, wherein like reference numerals refer to like parts throughout:

Fig. l is a perspective view of a rotary file constructed in accordance with and embodying the principles of the invention;

Fig. 2 is a vertical sectional view of the apparatus;

Fig. 3 is a vertical section on the line 3-3 in Fig. 2;

Fig. 4 is a fragmentary viewshowing, in elevation, a file retaining device and the cam for operating this device when a file compartment is in file-transfer position;

Fig. -5 is a horizontal section on the line 5-5 in Fig.3; and

Fig. 6 is a vertical section on the line 6--6 in Fig. 4.

Referring to the drawings, the file cabinet l0 includes a rotary frame or drum I2 mounted on a shaft-l4 that is carried by the cabinet Ill. The drum l2 carries a series of filing compartments l6 which are disposed around the periphery of the drum. The fiat top l8 of the cabinet in has a rectangular opening therein through which access may be had to the contents of a compartment l6 disposed in file-transfer position. The drum l2 may be rotated by a wheel 20 which is disposed outside of the cabinet l0 and mounted on the shaft [4, thereby to bring any selected compartment [6 into the aforesaid transfer position at which the contents of the compartment may be inserted or extracted.

The filing compartments [6, as they approach the transfer position, project slightly above the top l8. Arcuate flanges or rails 22 disposed on either side of the opening in the top It serve as guides for a lid or cover 24, Fig. 2, that may be slid into or out of position for closing the aperture. The cover 24 may be secured by a lock 26 when the filing cabinet is not in use.

In accordance with the invention, each of the filing compartments I6 is provided with a pair of retaining devices 28 which are secured to theouter faces of the drum l2 in any suitable manner on either side of the compartment l6.

These retainers 28 are in the form of fiat, wing-.

like members of yieldable material such as sheet metal, preferably having inherent resiliency and normally tending to lie against the outer surfaces of the drum [2. The upper ends of the retainers 28 are bent inwardly to afford lipsor flanges 30 which are adapted to overhang thecards, folders or other files in the compartment [6 when the retainers 28 are occupying their, The lips 3|] prevent the connormal positions. tents of the compartment Hi from falling out or being otherwise displaced when the compartments it are rotated from file-transfer position.

It will be understood that the retainers 28 may also be merely flexible or pivoted on the drum I2 I and urged inwardly by separate spring member if desired.

When the filing compartments iii are rotated into the file-transfer position, it is necessary that the retainers 28 be moved outwardly from the drum l2 to withdraw the lips 30 into their open positions as shown in Figs. 3, 5 and 6; For this purpose I have provided a pair of circular cam when the filing compartment I6 is approaching,

occupying or receding from the file-transfer position as shown in Figs. 3 and 5. Each cam 32 is Each cam 32 is of such configura 3 relieved as indicated at 36 in the vicinity of the file-transfer position to afiord clearance for the retainers 28 when they are in their open positions. At all other times in the course of travel of the compartment I 6 the retainers 28 are permitted to flex inwardly by the cams 32, thereby bringing the lips 30 into closed position wherein they are effective tb e gage the; upper edg'es ohthe cards or other files-iii the compartment and retain these 1 files against displacement.

My invention has the advantage that the re tainers '28 are subjected to positive camrn ingaction only when the associated compartments l6 are in or near the file-trainsfer position'. .QAt 2 all other times the retainers 28-are held-inwardly 1 by their own resiliency and may rige. l oosgly op the cams 32. The file contents are securely h against displacement by ,the retainers 28 when" they are in their closed fibsitions.
