Claims. (Cl. 24267.4)

This invention relates to a magazine for the storage of strip material and has for its principal objects to provide a storage chamber in which a master strip bearing a large amount of catalogued information may be supported for storage and for use, or a whole or a part thereof, without at anytime removing the entire amount. Another object is to provide a storage chamber for supporting the strip in such fashion that predetermined lengths of the strip may be exhibited in succession and at various constant or intermittent speeds. Another object is to provide means for supporting the strip in the storage chamber so that it can be exhibited throughout its entire length from either end and may at anytime in the course of its movement in one direction be reversed so as to be moved in the opposite direction. Another object is to provide spools for supporting the strip for movement from one to the other and for compensating for the change in effective diameter of the spools as the strip is wound from one to the other to afford uniform speed of the strip without slack or tension.

As herein illustrated, the storage magazine comprises a housing, means mounting a pair of spools therein in spaced relation upon which strip material wound on one may be wholly or partially transferred to the other, a port in a wall of the housing parallel to the plane of the axes of the spools, through which a loop of the strip passing from the one spool to the other may be drawn, means for turning the spools to transfer the strip from one spool to the other, and means for maintaining a loop of constant length exteriorly of the port. The spools are rotated by individual motors connected to their shafts and there is means controlling the motors to compensate for an excess or insufficient amount in the projecting loop due to the change in diameters of the coils on the spools as the strip is transferred from one spool to the other. The aforesaid means includes secondary loops within the housing, each being connected at one end to a spool and at the other end to an end of the projecting loop. These internal loops change length with the speed of pay-off or take-up of the strip on the spools and there is means operable by the change in length of these loops to increase or decrease the speed of the spools. The housing also contains tapes connected to the spools which lie between the interfaces of successive coilsof the strip for winding and unwinding with the strip to hold the interfaces out of contact with each other. Portions of the tapes between spools are supported on guides to form loops and there is means yieldably engaged with the loops to maintain them under tension.

The invention will now be described in greater detail with reference to the accompanying drawings wherein:

Fig. 1 is a vertical section from. front to back of the magazine;

taken on the line 2--2 of Fig. 1 I

"48 there is a loop 62.

Fig. 5 is a greatly enlarged section of a fragmentary portion of a roll broken away between its ends showing the strip and spacers between adjacent rolls; and

Fig. 6 shows the wiring diagram for the apparatus.

As herein shown, the storage magazine 10 is substantially rectangular in horizontal section, having a base 12, a top 14 and walls 16. Part way down the front wall slopes forwardly and then downwardly and the side walls and bottom walls extend forwardly to meet its edges and to form with the front wall a base of larger cross-section than the top part of the magazine. In the lower part of the front wall there is a horizontal substantially rectangular port or opening 24.

The magazine may be comprised of any suitable structural material such as wood, metal or plastic and preferably is fabricated so as to be substantially light and moisture-tight.

Within the upper and lower halves of the magazine there are journaled on suitable bearings 18, fastened to the walls 16, spaced parallel shafts 20, on which are mounted for rotation spools or reels 22, each of which has a barrel 25 and end flanges 26 rigidly fixed thereto. The shafts 20 extend through their bearings at one side to the exterior of the magazine and have fastened thereto pulleys 28, over each of which there is entrained one end of an endless belt 30, the opposite end being entrained about a pulley 32 (Fig. 6), fastened to a motor shaft 34 extending from an electric motor. There are two motors M and M at the base of the magazine on brackets fastened to the wall, one for each pulley. The motors. are reversible so that the spools may be turned in opposite: directions and are provided with means for controllingtheir speed of rotation or the effective speed of rotation:

of their extended shafts, independently of each other.

In accordance with the invention there is: wound on thespools a strip 40, a fragmentary portion of which is shown: in Fig. 3. bars 42, hingedly joined edge to edge and each bar has;

transversely thereof indicia, for example telephone listings: or alphabetically or numerically arranged catalogue in-- formation. As herein illustrated, the strip has arranged. transversely of it telephone listings which are taken from a telephone directory and is kept up to date daily orweekly, as will appear in my copending application Serial No. 67 6,807, filed August 7, 1957, for Finder for Quickly- Locating a Desired Item in a Long List of Items, by adding and/or removing bars 42 to the strip 40.

The information stored on this master strip constitutes a source for making copy of the same size, larger size or reduced size, as for example on microfilm, and it is the purpose of this invention to make the master strip available for such copying by exposing as little or as much thereof as desired at any given time for copying without removing the entire strip from its protective magazine. i

This is accomplished herein, as shown in Fig. l, by drawing the strip 40, wound on the upper spool 22 downwardly over a transversely disposed roller guide 44, into the lower part of the magazine, into a space in front of the lower spool 22 which was made available by enlarging the lower a part of the magazine. Within this frontal space there are transverselv extending guide rollers 48, 50, 52, 54, 56, 58 and 60. The guide rollers 50 and 52 parallel the edges of the opening 24 while the remaining rollers are either above or below the opening. As shown, the strip 40, coming olf of the upper spool, passes over the guide roller 44 i downwardly therefrom and then reverses itself and passes u wardly over the roller 48. Betweenthe rollers 44 and After passing over the roller 48 ,1 the strip extends down to the roller 54, hencerearwardly; to the roller 56, hence upwardly over the roller 58,- and hence downwardly and reverses itself OVCFthc I'QllCl' 6 0, So as to form a second loop 64 when hangs between the The strip is made up of a plurality of narrowrollers 58 and 60. From the roller 60 the strip runs onto the lower spool 22.

When the magazine is employed solely as a storage chamber the length of the strip between the rollers 48 and 54 passes directly from one to the other, wholly within the housing, as shown in full lines. When it is desirable to use or obtain from the strip information, the strip is drawn outwardly through the opening 24, as shown in dot and dash lines, to form a transversely extending loop 66, the latter being guided adjacent the edges of the opening about the rollers 59 and 52 which prevent damage to the strip and assist in guiding it. The loop 66 is supported by a suitable spool s which may be part of a copying apparatus a placed adjacent the magazine and located in a proper relation thereto by positioning pins pp, at its base which are adapted to engage holes h-h in the base on which the apparatus rests.

The different machines which are used in conjunction with the magazine will have means in the form of a spool s (Fig. 1), for engaging the loop 66 which will drive it at various constant or intermittent speeds. To prevent variation of the length of the loop 66 extending externally of the magazine due to change in the effective diameters of the spools 22 as the strip is unwound from one and wound onto the other, means is provided for varying the speeds of the spools, as will now be described with reference in particular to Fig. 6.

On the shaft 34 of the motor M there is mounted a clutch C and a brake B. The brake B is connected by lead wires c and through switch s and s to resistances R and R the latter being separated by a block of insulation m The clutch C is connected by lead lines c and c to. the same switches s and s to the resistances R and R The brush 68 is supported by the loop 62 (Fig. l) and guided by slots 69, so as to move along the resistances R and R as the length of the loop changes and is connected by a lead 0 to a conductor 0 which in turn is connected to an outside source of power by way of a switch s The motor M is grounded at g and connected through either of two lines 0 and c and a switch s to the conductor c As thus wired, as the strip 40 is unwound from the upper spool and wound onto the lower spool an increase in the length of the loop 62 results in the brush 68 moving downwardly along the resistance R thereby decreasing the resistance in the circuit (Fig. 6), so that morecurrent is supplied to the brake B by way of switch s and line 0 Increasing the current, increases the magnetic flux so that the braking action increases and hence slows down the rotation of the upper pulley 22, so that slack in the loop is taken up. If, however, the loop 62 is decreasing in length the brush 68 moves up along the resistance R which decreases the resistance and increases the current through switch s and line 0 to the clutch C, thereby increasing the flux in the clutch, which in turn increases the rotation of the spool. Increasing the rotation of the spool delivers the strip at a faster rate.

If the strip is to be unwound from the lower spool onto the upper spool 22 the switches s and s and s are thrown over to the dotted line positions. This reverses the direction of rotation of the motors M and M Now when the loop 62 increases in length, indicating that the spool is not taking up the strip 40 fast enough, the brush 68 travels downwardly along resistance R which reduces the'resistance and increases the current through switch .9 and line "c to the clutch, thereby increasing the speed of rotation of the spool so as to take up theexcess. If the loop is growing shorter the brush 68' travels upwardly, decreasing the resistance and increasing the current through switch s and line 0 to the brake B, "increasing the braking action" to slow down rotation of the spool.

The lower spool 22 is driven by the motor M and As heretofore stated, the strip 40 is made up of a plurality of narrow, parallel metal bars 42 (Fig. 3), which are hingedly joined edge to edge. The strip is quite long and sometimes Weighs as much as 1500 pounds. Constant use of the master strip for making copies, if precautions were not taken, would scratch the contacting surfaces so that good reprint could not be made. Accordingly, spacer tapes 84 (Fig. 2) are disposed between the coils and are arranged to be wound and unwound together with the strip. The ends of the spacer tapes 84, of which two are shown, near the opposite ends of the spool, although a larger number may be employed, are fastened to the barrel of the spool together with the ends of the strip 40 and as the strip is wound on and off the tapes are simultaneously wound on and off so as to be disposed at all times between adjacent coils and to hold them radially spaced, as shown in Fig. 5. To keep the tapes taut and to avoid movement thereof in the region where the strip is being reproduced they are led off the upper spool near the top thereof over transverseiy disposed roller guides 86 and 88 and back onto the lower spool near the top over correspondingly located, transversely extending roller guides 90 and 92. Tension is maintained in the tape by entraining loops 94-94 between the roller guides 88 and 92, about a movable guide 96 which is supported for vertical movement on a guide 98 and is operated upon by spring means 100 or a weight which constantly urges it downwardly to hold the tapes under tension.

As previously stated, when in storage the entire strip is concealed within the magazine and if desired a cover may be placed over the transversely extending front opening of the magazine to exclude dust and the like.

When in use the strip is drawn forwardly through the opening 24 to form the loop 66 of suitable size to accommodate reproducing means which is placed adjacent the magazine. Having engaged the spool of the copying means with the loop 66. the motors M and M are started and the strip travels from. one spool to the other at a constant. rate by reason of the aforesaid control. By

manipulation of the switch s and the connected switches 1 s s s and s the strip may be wound in either direction and by manipulation of the switch s the apparatus may be stopped and started when desired.

The spools 40 may be interchangeably mounted on the shafts 20, for example by set screws 102, so that the spools may be lowered and the shafts withdrawn. permit removal and replacement of the spools the wall 16 may have a hinged section 16*.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
