INDEX DEVICE Original Filed May 24, 1924 2 Sheets-Sheet 2 Patented Dec. 17, 1929 V UNITED STATES PATENT OFFICE JAMES H. RAND, OF NORTH. FALMOUTH, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO REMINGTON RAND ING., OF NEW YORK, N. Y., A CORPORATION OF DELAWARE INDEX DEVICE Application filed May 24, 1924, Serial No. 715,611.
This invention relates to index devices of the type wherein a series of index holders are hinged to swing on a support so that they may be readily manipulated somewhat after the manner of the leaves of a book when it is desired to inspect, or to insert or to remove the index units.
The objects of the invention are to provide an index device having parts or units which are independently movable so that several persons may inspect the index at one time without interferring with each other; and so that a single operator may simultaneously display selected portions of the units before him to enable the index holders tobe secured in a frame so that they may swing about substantially vertical pivots and in such a manner that one or more holders may be removed at one time; and to provide an index frame having certain novel features hereinafter described.
The genus of the invention is illustrated by the concrete embodiment shown in the accompanying drawings in which,
Fig. 1 is a side elevation of an index device constructed in accordance with this invention;
Fig. 2 is a transverse section taken on the line 22 of Fig. 1;
Fig. 3 is an enlarged fragmentary vertical section showing an index holder secured to a frame;
Fig. 4 is a view similar to Fig. 3 showing the manner in which the holders are removed from the frames; and
Fig. 5 is a fragmentary section showing the mounting for the top frame.
Referring to the drawings, the invention is illustrated in one preferred embodiment in which an upright post 1 is provided with threaded end portions 2 and 3, and the lower end portion 2 is connected to a supporting base 4 by means of nuts 5. A pair of index frames A and B are mounted in superposed relation on the post 1, and are adapted to rotate thereon. These frames are of like construction and consist of a top circular disc 6 and a similar bottom disc 7 which are integrally joined by a central tubular connecting rod 8. The outer portions of the discs Renewed August 6, 1926.
are braced by rods 9 which are screwed opposed faces of the discs 6 and 7.
The frames A and B are rotatable on the post 1 independently of each other and for this purpose the lower frame A is mounted on anti-friction bearings 11 which lie in an annular recess 12 in the bottom disc 7 and the upper race 11 for the bearings 11 bears against the bottomof the recess 12. A ring 13 surrounds the post 1 and is mounted on the base 4 to provide a support for the lower race 13. The upper frame B is likewise mounted on anti-friction bearings 14 which lie in a recess 15 in bottom face of the disc 7 and the lower race 14 is mounted on a ring 16. The ring 16 is supported on a split ring 17 mounted in an annular groove 18 in the post 1. The upper race 16 for the bearings 14 bears into against the bottom of the recess 15. Nuts 19 are threaded on the upper end 8 of the post 1 to hold the frame B in place and lie in a recess in the upper face of the disc 6.
In order to support index holders in the frames A and B, the lower faces of the top discs 6 are formed with an annular series of pockets 21 adjacent the outer edge thereof separated from each other by webs 22. The upper faces of the bottom discs 7 are also formed with an annular series of pockets 23 which are not as deep as the pockets 21 and are spaced from each other by webs 24. The pockets 21 and 28 are of equal length and a pocket in the lower disc directly corresponds to a pocket in the upper disc.
The index holders 25 are in the form of panels having opposed flanges 26 and 27 forming channels for receiving the index slips 40 on which desired indicia 41 are inscribed and having tabs 28 ordinarily bearing initials to indicate the names or subject-matter of the index slips which are normally concealed by said holders due to the face-to-face position thereof. The index holders 25 are provided with pintles or arms 29 and 30 at their opposite ends, the pintles 29 are slightly longer than the pintles 30. The index holders are mounted in the frames by inserting the pintles 29 into the pockets 21 and moving them upwardly until the pintles 30 can be swung in wardly and inserted in the pockets 21. The
holders are supported on the lower pintles 30 and the upper pintles 29 extend a slight distance into the pockets 21 so that the holders may swing about substantially vertical axes. The webs 22 and 24 space one series of index holders 25 from another series and prevent them from assuming inclined positions in the frames.
Rings 31 surround the periphery of the top discs 6 and are adapted to prevent the index holders 25 from being accidentally removed from the frames A and B. The rings3i are provided with cam slots 32 which are movable on screws 33 fastened to the discs 6. Lugs 34 are secured to the rings 31 to enable the rings to be conveniently rotated through a part of a revolution. By rotating the rings 31 in' a counter-clockwise direction (Fig. 2) the screws 33 guided in the cam slots 32 cause the ring tomo-ve upwardly away from the :index holders and thereby permit one or more index holders to be removed fromthe frames, as-indicated in Fig. 4. Rotation of the rings 31 in the opposite direction causes them to move downwardly by means of the slots 32 and screws 33 and thereby prevent the index holders from being lifted upwardly and with- 'drawnfrom the frames (Fig, 3). The index frames A and B'can be rotated independently of each other and'the index holders are prevented from being accidentally removed therefrom as above pointed out. 'aremanipulated somewhat afterthe manner of the leaves of a book about substantially vertical axes when it'is desired to inspect, al ter the index slips or for any other reason. In applying-theinvention to an alphabetical index a portion of the alphabet is carried by one frame and another portion by the other frame, whereby different operators may operatesimultaneously in the-respective portionof the ind-ex without interfering with each other: and-the index may bedivided into as many sections as desired by providing the desired number of separately rotating frames.
