Specification of Letters Patent.

Patented May 21,, 1907.

Application filed March 2'7, 1905. Serial No. 252,290.

To LLZZ whom it rim/y concern.-

Be it known that we, FERDINAND I-I. SonULTZ and MARTIN H. BERKEMEIR, citi- Zens of the United States, residing at Treynor, in the county of Pottawattamie and State of Iowa, have invented a certain new and useful Index-Machine, of which the following is a specification.

The objects of our invention are to provide an index machine in which there is a series of key actuated members upon which the index cards are designed to be placed, in which the keys in it and the parts operated by them are so arranged that the operation of a single key will throw the card bearing the same letter as the key to a position where it can be easily seen and a single operation of another key will cause the first mentioned card to return to a position inside of the casing at the same time another card bearing the same letter as the last mentioned key is drawn to a position where it can be easily seen.

A further object is to provide a key returni ng mechanism for simply returning the card which has been thrown out to the position where it can be seen to a position inside of its casing without withdrawing another card.

A further object is to provide an index machine in which there can be placed any number of cards desirable, operated by keys, and thus be adapted for use where a large number of names or a small number of names have to be indexed.

A further object is to provide a holder for the various indexes so constructed that the cards used for indexing the names may be easily removed whenever it is desirable to make up a new list of names.

A further object is to provide a muffler against which the various index carriers are to strike in being returned so as to eliminate to a great extent the noise which would otherwise be prevalent with the use of the machine.

A further and very material object is to provide a device of this class in which the in ex portion of the device may be kept from dust and other similar accumulations and at the same time be readily and easily accessible by the simple operation of touching a key.

Our invention conslsts in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the device. Fig. 2 is a longitudinal, sectional view of a portion of it designed to show the operation of the keys on the index carrier. F1g. 3 is a detail view of one of the index carriers detached from the rest of the machine. Fig. 4 is a front elevation of the device, showing one of the index sheets ex osed to view, and Fig. 5 is a detail, seotiona view of the lower portion of one side of the index carriers, showing the way of mounting these, and the mechanism by which they are operated.

Referring to the accompanying drawings, it will be seen that we have provided a base, comprising the two sides 10 and. 11 which are connected at their forward end by the keyboard 12 having a series of slots 13, 14, 15, 16, 17, 18 and 19, which extend from the u per to the lower portion of it. There may c any number of these slots to rovide for any number of keys that it may e desirable to use in the construction of our index machine. Extending upwardly from the central portion of the sides 10 and 11 of the base is a casing having the sides 20 and 21 therein and the top portion 22, said sides being connected at then rear portion by the back 23 which is partially opened for lightness in construction.

Extending across the base and mounted in that portion of it to which the sides 20 and 21 of the casing is attached is a shaft 24, which shaft is supported at its central portion by means of the upright 25, which upright is attached to the bottom 26 of the base. This upright 25 also serves as a retaining mechanism for securing the returning key 27 in position relative to the shaft 24, which passes through the slot 16 and has a cap 28 upon which is marked the word Return, or some other suitable word to indicate that this key is the one which returns the indexes into the casing in the manner hereinafter specified.

Pivotally mounted on the ends of the shaft 24 and outside of the sides 20 and 21 of the casing is a rod which extends forwardly from its point of attachment a short distance, and then extends across the device above the base 26. We have indicated this rod by the numeral 29. For the sake of convenience we have designated this rod, the returning rod. Securely attached to the ends 30 and 31 of this returning rod are the arms 32 and 33.

Pivotally attached to the side 20 of the casing is a lever 34, which lever is connected at its forward end with the forward end of the arm by means of the rod 35. The rear end of the lever 34 has attached. to it a spring 36, which spring is attached at its upper end to an adjustable support, which support comprises a slotted sliding member 37, and a thumb screw 38 which is inserted into the slotted member and into the side 20 of the casing so that the tension of the spring may be increased or diminished by adjusting the slotted member 37, and fixing it in a desired position.

Pivotally attached to the side 21 of the casing is a lever 39 corresponding to the lever 34, the forward end of which arm is connected with the lever 33 by means of the rod 40. Pivotally mounted on the shaft 24 is a rod 41 extending across the device above the base, and having its end portions 42 and 43 bent substantially at right angles to its body portion, and it is through these end portions that the shaft 24 passes. The body portion of the rod 41 is the transverse portion of it, and this is beneath the returning rod 29, and it is upon this rod 41 that the keys for operating the index carriers rest normally, and which maintain these rods Y at their upper limit of movement, as hereinafter set forth.

Pivotally connecting the lever 34 with the end 42 of the rod 41 is a rod 44. Connecting the rear end of the lever 39 with the end 43 of the rod 41 is a rod 45. Inasmuch as the spring 36 normally holds the return end of the lever 34 at its upper limit of movement, the rod 44 will be held at its upper limit of movement and will correspondingly hold the rod 41 at its upper limit of movement, and the rod 45 co-acting with the lever 39 and the rod 40 which is connected with the rod 29 will also assist in maintaining the rod 41 at its upper limit of movement and thus nor mally support the operating keys, hereinafter described, at their upper limit of movement.

Pivotally mounted on the shaft 24 is a series of index carriers, each of which has the side portions 46 and 47 and the curved top portion 48 in which is placed a card 49 having a series of lines thereon like those on the ordinary index card. Each of these curved top portions has a series of retaining lugs 50 for securely holding the card in position relative to the curved top portion, and yet enable the person using the index machine to remove the card therefrom at his pleasure. These carriers are made to telescope inside of each other and the largest carrier has its sides 46 and 47 adjacent to the sides 21 and 20 re spectively of the casing, and the one next in size is immediately inside of this and so on,

until the desired number of carriers has been pivoted on the shaft 24. Each of the sides 46 and 47 of the carriers extend a slight distance below the shaft 24 and every other one of the extensions to the sides 47 have the lateral projections 51 which are to be engaged by the operating keys, for throwing the carriers on which these lugs are, to their forward limit of movement where they can be seen by the operation. of the operating keys the first, third, fifth, and in consecutive order the odd numbered carriers commencing at the left have these lugs upon them. On the even numbered carriers on the extension of the side 46 below the shaft 24 is a projection 52 corresponding to the projection 51, which are designed to be engaged by the keys for operating the even numbered carriers commencing from the right of the machine. Attached to the lower end of the extension of the side 47 and on each odd carrier is a spring hook 53. Attached to the lower end of the exten* sion of the side 46 of each of the even numbered carriers is a similar hooked spring 54, all of which springs 53 and 54 are designed to coact with the rod 55, which extends across the base and attached to the sides 10 and 11 of it for normally holding the carriers in their closed position inside of the casing, and which are designed to be released by the operation of the operating keys. The free ends of each of these springs 53 and 54 are indented to receive the broad portions of the keys hereinafter described.

Pivotally mounted on the shaft 24 and between the first and second sides 47 of the index carriers and the third and fourth sides 47 of the index carriers, and so on is a series of keys, 56, 57 and 58 which extend outwardly from their pivotal points of attachment, the rod 29 resting upon the rod 41 and passed through the slots 1.3, 14 and 15 respectively. Each key has a cap upon which is a designating letter corresponding to the indicating letter on the index carrier, to be brought into sight by the operation of this key. Any number of keys and a corresponding number of carriers may be used.

Extending between the second, third, fourth and fifth carrier, commencing with the right and coming to the left are a series of keys 59, 60 and 61 for operating the even numbered carriers which are pivoted to the shaft 24 and extend outwardly in the same manner as the keys 56, 57 and 58 extend and constructed exactly like them.

Attached to the rear upper portion of the back 23 of the casing is a mufiier 62 against which the rear edge of the index carriers are designed to rest in their closed position which. is designed to prevent the index carriers from creating a noise as they approach their inner limit of movement.

In practical operation and assuming that the parts of the device are assembled in the manner above designated and that the index carriers are on the interior of the casing as shown in Fig. 1 of the drawings and that it is desirable to obtain access to the index on the index card marked A to D, the operator places his fingers upon the cap of the key 56, forces it downwardly, and this will cause the rod 41 to be forced downwardly and at the same time draw the rear end of the levers 34 and 39 downwardly against the resistance of the spring 36 and thus cause the rod 29 to be raised slightly. The downward movement of the key is continued until it forces the spring 53 out of engagement with the rod 35, so that the carrier willbe released from its locked position and the key will engage the lug 51 and force the carrier and index into the desired opening outside of the casing where the sides 46 and 47 of the carrier rest upon the rod 29, the spring 36 having drawn the parts connected with itback to their normal position. When it is desired to simply return the index carrier to the interior of the casing, the operator places his finger upon the return key 28 and presses downwardly upon it,

which forces the rod 41 downwardly and correspondingly draws the rod 29 upwardly and forces the index carrier into the interior of the casing. In doing this, however, the return key 28 has to be moved downwardly with some rapidity in order to throw the carrier past the dead center and toa normally closed position where it is locked by the spring 53 coacting with the rod 55. However, if the index carrier is in its open position and it is desired to force this carrier to its closed position inside of the casing and by the operation of a single key, force another index carrier from the interior of the casing to the exterior of it, this can be done by simply pressing downwardly on the key 57, for illustration, by moving this key downwardly with some momentum, when the index carrier which is in its open position will be forced to its inward position in the same manner as if the key 28 was pressed downwardly, and at the same time by continuing to press the key 57 downwardly, it will force the spring 53 on the carrier to be thrown out to its open position and engage the lug 51 on said carrier and throw it to its outer limit of movement. By this operation the forcing of one carrier into the casing and of forcing another carrier to a position outside of the casing can be accomplished by the operation of a single key. The returning key, there fore, need only be used when the operator desires to have all of the carriers on the interior of the casing. If, at any time the keys are not maintained in the proper position, the position may be easily adjusted by the adjustment of the tension of the spring 36.
