Application filed June 19, 1923. Serial No. 646,400.

This invention relates to a mechanism for storing a considerable number of information carrying means and for bringing to view any one oflsuch means in a rapid and efficient manner.

The object of the present invention is to provide a device of the character described wherein the information carrying means may be restored to storage position by the same means which brought it to View.

A further object of the present invention is the provision of a device suitable for the keeping of commercial accounts in which each account may be kept upon a separate card which may be removed temporarily or permanently at will and which when in the machine can be brought to view so that it may be written upon and may be restored to storage position with a minimum of time and effort.

A still further object of the present invention lies in the provision of means for supporting a plurality of independent records upon a flat rotatable spool and means for r withdrawing the spool from storage.

Other and further objects of the present invention concern the specilic details of construction of the apparatus illustrated, these objects being specifically recited in the claims.

ln an almost infinite variety of fields a considerable number of records of various kinds are required to be kept in such manner that any one of'these may be almost instantly available. Such records may be accounts,

' descriptions, photographs or drawings or even small samples and the present invention is concerned with each of these different ob- `ects. For convenience of description and of illustration the invention is shown as applied to a device having records all of the same size but I wish it distinctly understood that the records may be of different size and may be of any size and shape that may be conveniently mounted upon the flexible band which I secure to the spools vcarried'by the large storage receptacle, magazine or spool carrier.

A very convenient illustration of the use and y operation of the device will be in connection with the keeping of commercial accounts and the description will therefore be direct-ed to a selector having that definite object in view.

In the dra-Wings,- Figure 1 is a side elevation of the device with a portion of the casing removed.

Fig. 12 is a section through the spool While on the reel.

Fig. 13 is a front elevation of the rod Y which is secured to one end of the record carrying band mounted on the spool.

Fig. 14 is a View of the rod, band and spool showing the parts in extended position but detached from the selector mechanism.

F ig. 15 is a view of the parts ready to withdraw a spool from the magazine.

The main frame 10 is preferably of-boxlike or casing construction comprising a base, sides, and ends, but with a top extending only over a portion of the box as .illustrated at 11, such top portion having awindow therein as at 12 above which an instrument such as a book `typewriter (not shown) may be supported. The remainder of the top of the casing is preferably formed by a thin metal hood or shield 14 domed to cover the large disks 15 which foi-ms the storage receptacle or magazine for holding the records and their supporting spools. The sides of the frame or casing are indicated at 10a, the end o f said casing at 10", and the base of said casing at 10c. In addition to the Window 12 and that portion of the casing through which projects the magazine 15, said casing has its sides 10a out away as at 10d for accommodation of the stops or buers 54, 55 for the carriage 50. Thev disks 15are mounted on a shaft 16 which extends through the two sides of the frame or easing, the disks 15 being non-rotatably mounted on the rotating shaft 16 which carries at one end a small pinion 17 meshing with a sliding4 rack 18 by means of which the disks are rotated to an desired angular position. YThe magazine as two large circular disks each slotted as at 20 to receive the records or card preferably carried by these spools 21 shown in Fig. 11. For convenience in illustration I have shown but twenty slots .20 but intendi-,o have one hundred equally with small dollars 26.

The flexible band 23 is provided with means 'for holding a plurality of records of any kind which will usually be paper or card board rectangles such as indicated at 27 and if desired these cards may be held .on the band b Ameans of parallel slits 28 engaging each o the four corners of the record card or other information carrying means. Since the decimal system is the most convenient I provide ten records to each spool so that with one hundred spools to each spool support each selector will carry a thousand records.

At the far end of the casing a platen, preferably in the form of a hollow drum 30 1sv pivoted on a pair of links 31 which in turn are pivoted to the casing as at 32 so that the drum may revolve about its pivotal connection 33 with the links 31 and at the same time may oscillate about the ivots 32 within the limits permitted. A- coiled spring 36 .is secured at one end to the drum 30 and at the other end to the shaft 33 on which the drum 30 is pivoted, this shaft, however, being nonrotatable in the links 31. J

- An L-shaped member 40 secured tothe casing limits the oscillating movement of the drum and also its revolution about the axis 33 when the drumi30 is in forward position as shown 1n Fig. 1. It will be noted from this figure that the shaft 33 is in contact with the rear edge of the upright member of the L- shaped stop 40 and that the small pin 41 is in contact with the upper surface of the. lower leg of the L 40, the tendency of the lspring 36 being to rotate the drum in a clockwise direction'a's seen in Figs. 1, 3 and 4.

The means for transferring the spools from the stora e receptacle to the revolving drum 30 inclu es a carriage 50 mounted on rollers 51 traveling on tracks 52, a convenient form of the track being T-shaped and the roll'ers 51 therefore being of the double `flange type best seen in Fig. 6. The carriage has a relatively short travel, engaging buffers 54 at the forward end andsimilar buffers 55 'l riage preferably lie flush with the front and l rear portions of the sides of the casing 10 and are tongued as seen in Fig. 6 to engage a groove 58 in the top section of the sides. This tongue and groove construction cooperates with the four rollers 51 in guiding the carriage smoothly in its travel.

Referring now particularly to Fig. 9, the carrier consists of three principal parts, namely, the carrier block 60, the shaft 61 fast on the block 60, which serves as an axle, and the retaining member 62, the latter being hinged to the block as by the links 63 and urged upwardly by a spring 64 to close the slot 65 in the carrier-block 60. The parts are shown in both Figs. 9 and 10 with the retainer depressed but in Working position. the retainer is elevated closing the slot and preventing the withdrawal therefrom of the lug .22 of the spool 21.

.shaft 67 of the carrier 66 carries a pinion 68 which is driven by a rack 69 having a handle 70. -These carriers illustrated in detail in Figs. 9 and 10 serve to support -the spools while the band 23 of a spool carrying the record is being unwound onto the drum 30 for the` purpose of exhibiting one of said records through the window 12 of the casing 10.

At the rear end of' the frame, that is, to the right as seen in Fig. 1, the carriers 60 and 66 are freely rotatable but when the carriage 50 is at the left as seeniin Fig. '1,' i. e.`in forward or receiving position, a ledge 71 secured to the casing rests rather snugly against the top of the block 60 and the corresponding part of the carrier 66 and prevents either car-.

the right as seen in thevarious figures the drum 1s in normal position, that is, pressed forward so that the pin 84 is but slightly above the lowest point of thc latch but as the bumper 86 of the carriage engages the link 31 driving it'back to vertical position the latch 80 rides over the pin 84 and remains in contact with it.

A socket or fork 88 is pivoted to the cardrum'30. When 4the carriage 50 is moving to Lesa/4.91

riage as at 87 but is limited in its oscillating movement by a pair of stops 89 and 90 holding the socket in vertical or horizontal position, respectively, the latter being the normal position.

rllhe operation of the device is as follows: A given record card, let us say No. 252 is desired. The first operation is to revolve the magazine 15 by means of the rack 18 and its handle 91 until the numeral 250 on the scale p 93 is opposite the indicator mark 92. Upon The handle 70 of the rack 69 is now pulled to the rear, that is, to the right as seen in Figs. 1 and 2. If the carriers were free of the ledge 71 this action would revolve the carriers but since each of the carriers is locked by its engagement with the ledges 71 the only effect of pulling the handle 70 is to move the carriage rearwardly on its track 52. Upon such movement of the carriage rearwardly the sockets 88 engage the rod 25 and simultaneously the carrier blocks 60 and 66 engage the tabs or lugs 22 of the spools 21 and the parts move forward a slight distance in this position at which time the standard 74 of the retainer 62 is freed fromvengagement with the ledge 72 and the retainer 62 promptly moves upward closing the slot 65 with the tab therein.

The carriage now moves rearward until the bumpers 86 engage the links 31, moving the drum 30 rearwardly to its highest point with the links 31 vertical. This action releases the pin 41 from engagement with the L40 and allows the drum to rotate by virtue of the vtension of its spring 36.

The drum has a plurality of hooks 96 which catch and engage the ends of the rod 25 as the drum revolves. The pivoted sockets 88 being released from the ledge 71 offer no resistance to the passage of the rod 25 now carried by the hooks on the drum and are turned to a substantially vertical position and are so held by the relatively long pivoted links 97 which are held against stop lugs 98 on the frame by means of springs 99. The links 97 are pivoted to the casing or box and by holding the sockets 88 in a verticalposition not only keep the sockets out of the way of the revolving mechanism but also hold them in proper position to receive the rods when thespools are ready to be returned to the magazine.

A slight further rearward movement of the carriage allows the rack 69 to revolve the carriers about their shafts 61 and67 unwinding the band 23 from the spool 21 and allowing it to wind on the spring rot-ated' drum 30. The rack 69 is driven rearwardly until the pointer 100 is opposite the numeral 3 on the scale 101 at which time three folds of the band will have been wound' on the drum 30 so that in Fig. 4 the record card 27 bearing the number 250 will be at the bottom of the drum, the next c ardNo. 251 will be at the rear side, and the desired card No. 252 will beat the top where itis visiblelthrough the window 12 and may be Written upon if desired. A. small spring pressed lug such as102 may bc provided to frictionally engage the drum to hold it steady in writing position if de-y sired butI usually omit this spring as I find it unnecessary in practice. y

After the card 252 hasbeen written upon, the rack 69 by its handle 70 is pushed forward until the lug 103 carried thereby engages the stop pin 104 on the carriage 50, this construction prevent-ing the overrunning of the carriers and' spool should the carriage.

for some reasonk fail tol move forward prom-ptly. There is a small notch 105 in the upper portion of one of the sides of the carriage and this Vis engaged by a spring pressed catch 106 pivoted to the side of the casing so as to prevent the carriage from moving forward until the rack has moved forward with the lug 103 in contact with the stop pin 104. At this time or very slightly before this the trip 109 carried at the front end of the rack 69 engages and depresses the frontpart of the pivoted catch 106 allowing the carriage to move forward.

is previously stated the first operation resulting from the moving forward of the rack is the revolvingv of the carriers which serves to rewind the band 23 on the spools 21 and to revolve the drum 30 against 4the tension of its spring 36. As the band un winds from the drum the rod is above the now vertical sockets 88 and the hooks 96 free themselves from the rod by moving past these sockets upon the further movement of the drum whenl the carriage moves forward.

As the carriage starts to move forward the latches 80 engage the pins 84 and pull the drum forward' about the pivots 32 into engagement with the L 40 further rotating the drum against the tension of its spring, causing the hooks to travel below the path of the rod, thereby freeing the spool from'connection with the drum and also locking thefdruxn against oscillation about either set of pivots. The latches 80 ride over the pins 84 when the latter are lowered by movement about Vthe pivots 32.

Forward'movement of the carriage brings the carrier blocks into engagement with the ledges 71 which retain them' in the horizontal position to which they were brought at 104 and this ledge also turns the sockets88 v into horizontal posit-ion against their stops 90.l With the various parts in this position the standards 74 of the retainers 62 are depressed at the end of the stro-ke by engagement with thesomewhat rounded edge of the ledges -72 this engagement occurring only after the lugs 22 have reentered the appropriate'slots 2O inthe magazine and have reached the limit of the slot. .The carriage, however, moves a still further distance back so that the carriers and the sockets entirely free the spool and rod permitting the magazine to turn freely to'bring the next desired spool to withdrawing position.

Under certain circumstances I find it pref erable to lock the magazine positively when the carriage has moved rearwardly. A very vsimple formot lock and latch is shown in Figs.

1, 2, 3, consisting of lan L-shaped lever 110-centrally pivoted as at -111 with one end 112 adapted to mouth of the slot 20 in'pone of the disks and carrying at its lower end a small roller 114 adapted to be engaged by a projection 115 carried by the front end of the carriage y50. The spring 116 which operates the leverll() I is supported from a small lug 117 which also supports a spring pressed guiding drag 118 which remains in constant engagement -with the disk but which does not prevent the disk from revolving when the rack 18 is moved this spring 118, serving merely to insure greater accuracy in the registry of the desired slot 20 with the slots in the carriers. The arcuate shield or guard 119 constituting the mechanism for preventing the removall of the cards, records orspools best seen inV Fig. 5 serves to -40 revent the spools or records from leaving thev magazine except at the proper or withdrawing position, and at the top of the magazine wzhere a slot 120 isprovided to permit easy replacement of a spool without recourse to the carrier mechanism.
