LEO S. ROBINSON, F ALAMEDA, CALIEORNIA.

smanmmas am? Application filed December 30, 1918. Serial No. 268,974.

To all wko/m it may concern:

Be it known that I, Lno S. ROBINSON, a citizen of the United States, and a resident of the city of Alameda, county of Alameda,

State of California, have made a new and useful invention, to-Wit, a Segregating Apparatus, and I do hereby declare the following to be a full, clear, concise, and exact de scription of the same.

This invention relates particularly to the means and the manner of segregating index cards, and will be described in that connection. I do not wish to be understood, however, as limiting this invention to that part-icular adaptation, because stencils, and any form of sheets or plates, hereinafter designated as units, may be similarly segregated.

Among the objects of this invention are to facilitate the introduction of segregating rods through the mass of perforated units with the minimum of resistance and injury or wear on the units and the apparatus.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

It is often desirable to string cards and similar units on a rod. but in practice it is found very difficult to insert a rod through a perforated mass of cards without injuring the cards and it is found necessary to make the holes in the cards very large and theI rod comparatively small. The cards.l if set in a tray or box similar to the ordinary index card tray, take an incline or slant and fall in such positions that the holes in the cards are out of alignment.

This invention provides a simple method and means for introducing a rod through a mass of perforated cards, all of Which have been provided with registering holes.

In the accompanying one sheet of drawings,

Fig. 1 is a cross section of a box or trav having perforated index cards therein resting upon the bottom of the tray. This digrammatically illustrates the first step in the practice of this invention.

Fig. 2 is alongitudi'nal section of the same.

Fig. 3 is a view similar to Fig. 1 showing the second step in the method.

Fig. 4 is a longitudinal section of the same.

Fig. 5` is a View similar toI Fig. 1 showing the final step in the manipulation of the card.

Fig. 6 is a longitudinal section of the same.

Fig. 7 is a fragmentary end view in cross section of the tray bottom having a moditied form of unit elevating means thereon, in the inoperative position.

l"ig. 8 is asimilar view of the same in the operatlve position.

Fig. 9 is a plane view of a modified form of unit. y

The drawings show the invention in its elementary form, the several views being diagrammatic. The invention is susceptible of various modifications to suit its various ape pheations in connection with card systems and the like. For further particulars, reference may be had to my United States Patents bearing No. 1,223,113 dated April 17, 1917, and 1,235,502 dated July 31, 1917 relating to card systems.

In detail the construction illustrated in the drawings includes,

A box or tray comprising the front 1, the back 2, the sides 3 and 4 and the bottom formed 0f the strips 6 and 7, properly assembled to form a tray or box open at'the top and having a longitudinal space or openlng 9 in the bottom. lVhere the tray iS of considerable length, it may be provided with a transverse partition intermediate the front and back 1 and 2. The front and back are provided with the aligned holes 11 and 12 respectively. These holes are arranged in a geometric pattern and in the present in. stance are made equal distances apart in horizontal andvertical rows.

The cards 13 are eut to stack-transversely within the tray with suliicient lateral freedom to allow free play within the tray when being manipulated. These cards are provided with a series of master holes in the same pattern that center perfectly with the holes 11 and 12. The lateral margins of these cards are provided with the vertical guide slots 14 and 15.v The tops of these

slots

14 and 15 are cut to align horizontally with their companion slots on the opposite margin of the cards. Certain of the master holes in vertical alignment are cut together rods 22, indicated by black dots, cannot be.

inserted through the'holes in the cards.

To facilitate the introduction of the guide rods 22 through the

guide slots

14 and 15 the elevating block 23 is inserted in the opening 9 between the bottom strips 6 and 7.

The thickness of this block is greater than the thickness of the bottom strips 6 and 7 so that when the tray with the block therein is laid on the table top X the stack of cards is elevated as shown in Fig. 3. This elevates the

slots

14 and 15 well above the level of the rods 22 which may then be inserted through the

holes

24 and 26 in the front and back l and 2, and through their

respective slots

14 and 15 in the cards. The block 23 is then removed which leaves the Whole stack of cards suspended by the tops of the

slots

14 and 15 on the rods 22 as shown in Figs. 5 and 6.

Thus suspended on the rods each card hangs pendulum fashion, perfectly vertical, with a consequent perfect alignment of all of the master holes 17 through the cards; this also centers the master holes 17 in the cards with the holes 11 and 12 in the front vand back 1 and 2 of the tray. Thus suspended, the segregation rods 21 may easily be threaded through the openings 11 and 12 and the master openings 17 in the tray and the cards respectively.

By this arrangement of suspending the cards, extreme accuracy can be attained in aligning the master hole 17 and maintaining parallel the opposite plane surfaces of the cards, This is not possible where the cards rest upon their bottom edges 19 and become warped by their own weight and the leaning or inclination that they are bound to take in thus standing. It is necessary in effecting segregation that these cards slide freely one upon the other. It is important therefore, that the frictional contact between the surfaces of the cards be reduced to the minimum. This is also a beneficial result following the suspensionY of the cards on the guide rods 22 as described.

The perfect, registering alinement of the master holes in the assembled cards avoids any frictional resistance to the passage therethrough of the various rods. This reduces wear and tear on the cards and prevents enlargement of the various holes and slots, that would result if the operator used violence in forcing the -rods through'a resisting card assembly wherein each unit was not. so accurately alined.

In effecting segregation of certain designated cards from the mass of cards all the cards having slots, such as 18, that are in horizontal alignment can be moved upward with respect to the segregation rods 21 pass ing through the uppervportion of the slots 18, such slotted cards being movable with respect to'their rod, whereas the unslotted cards are held down because of the master holes engaging the segregation rods.

Separation of the slotted cards may be effected by inverting the drawer or tray,such slotted cards fallin by gravity and agitation to the limit of t e length of their respective slots, which is a distance equal to the distance between the horizontal rows of master holes. The lower cards may be held in this extended position by inserting another segregation rod above the bottoms 19 of said cards, then returning the tray to the upright position, such segregated cards remaining extended above the unslotted cards, engaging the segregation rods.

The slots 18 formed in any one of the cards have a specific significance determined by their location in the card. In this manner any classified cards may be segregated at will by introducing segregation rods at appropriate locations.

As a substitute for the elevating block 23, a modification is illustrated in Figs. 7 and 8. This consists of the longitudinal strips 28 pivoted on the pins 29 passing through the brackets 31 fixed at 32 to the end of the bottom strips 6 and 7 between the ends of the strips 6 and 7 and the ends of the tray land 2. The ends of these strips 28 may be provided with small round-headed studs such as 33 adapted to engage a hole at 34 in the end of the strip 31 to act as a catch t0 maintain the strips 28 in their respective positions. The strips 28 are rotatable upon their pivots 29 and are slightly wider than they are thick, so that they may be turned into the positions indicated at Fig. 8 with the greater width vertical, thus elevating the mass of cards above the bottom strips 6 and 7 performing the same function as the elevating block 23 by means of devices assembled permanently within the index tray.

Fig. 9 illustrates a modified unit, applicable to the segregation of address stencils. The

lugs

14 and 15 having notches thereunder to engage the guide rods 22, perform the same function as the

slots

14 and 15. The master holes 17' can be cut together to form classification slots as at 18', the mode of operation being the same as previously described. Other modifications within the spirit of this invention will suggest themselves to those skilled in the practice of this art.
