6 Claims.

This invention relates to magazines for magnetic recording apparatus and more particularly to wire supply magazines adapted to be detachably connected to magnetic recording or reproducing devices to carry a supply of wire therefor.

In handling wire for apparatus of this type, the wire tends to unwind from the spool on which it is carried when the machine is not in operation. When the spool is carried in a housing or casing, the wire has 'a tendency to spring over the flanges of the spool and to become tangled between the spool and the housing if tension i's not maintained on the wire.

It is one of the objects of the present invention to provide a magazine carrying a spool of wire in which the wire is prevented from springing over the spool flanges.

Another object is to provide a magazine including means yieldingly engaging a flange on the spool to hold the wirel on the. pool.

Still another. object is to provide a magazine in which the spool is held against one end of the housing when the housing is detached from the apparatus and spring fingers are provided engaging the spool flange which is spaced from the housing and to prevent the wire from springing over the flange.

The above and other objects and advantages of the invention will be more readily apparent from the following description when read in connection with the accompanying drawing, in which- Figure 1 is an axial section of a magazine embodying the invention.

Figure 2 is a section showing the position of the magazine parts when installed on a recording or reproducing apparatus; and A AFigure 3 is a section on the line 3-3 of Figure 1. i

The magazine of the present invention comprises essentially a housing which'is adapted to be detachably mounted on a recording or reproducing apparatus and which carries a spool or' wire to be supplied to the apparatus. The housing, as shown, is formed of non-magnetic metal, plastic or the like and includes a main I housing part forming an end wall I0 and an annular side wall II shown as integral with the end wall. The end wall I is formed with a central opening I2 to receive. the shaft of the recording or reproducing apparatus and with an eccentric locating opening I3 to receive a locating pin on the apparatus. A fastening plate It is secured to the end wall l0 and projects beyond the periphery of the housing to be engaged by suitable fastening means on the apparatus. As shown, the end Wall III is offset outwardly at its central portion for a purpose to appear later.

The main housing part is closed by a second end wall I5 secured to the side wall II as by stak ing, welding or the like. As shown, projecting fingers I6 on the side wall extend through openings in the end wall I5 and are bent over to secure the end wall in place. The end wall I5 is formed with a circular flange Il extending partially over the side wall I i and terminating short of the'fastening plate I4 to provide space for an annular rotatable gate member I8. The gate member I8 is in the form of an annular strip having an opening I9 therethrough to register with a corresponding opening 2| in the side wall II when the gate is turned to the proper position. To facilitate turning of the gate, a finger 22 is secured thereto to be engaged by the operator.

A spool is mounted in the housing and may be formed in any desired manner of sheet metal, plastic or the like with a central hub portion 23 and end iianges 24 and 25. The endl flange 24 lies next adjacent the end wall I0 of the housing and is of a size to fit within the recess therein so that when the parts are in the position shown in Figure 1 the iiange24 and outer portion of the end wall I0 provide a substantially smooth surface. The spool is urged toward the end wall I0 by a spring shown as a leaf spring 26 carried in the housing and engaging the adjacent end of the spool. The spool is formed' with an opening to receive the shaft of the apparatus and the spring 26 preferably overlies the opening so that it will be engaged by the shaft when the magazine is installed on the apparatus.

To prevent wire on the spool from springing over the ange 25, the housing is provided with annular spring means yielding to engage this flange. As shown, the spring means comprises an annular series of inwardly extending spring iingers 21 yieldingly engageable with the inner face of the flange 25 to prevent wire on the spool from passing between the flange 25 and the housing. The spring fingers are conveniently bent fron an annular spring strip 28 fitting within the housing and are preferably closely spaced as best seen in Figure 3 to leave no space through which wire could pass.

When the spool is detached from the apparatus, the parts will occupy the position shown in Figure 1 with the spring 26 pressing the ange 24 into the recess in the end plate I0 and with the spring fingers 21 engaging the inner face oi the ange .25. Preferably the spring 2 is stronger than the spring fingers 21 so-that the spool will be end of the housing, and annular spring means in v.the housing engageable with the inner face of urged against the end wall I0. With the parts.

When the magazine is installed on a recording I or reproducing device, the shaft of the device indicated at 29 will extend through the opening in the spool to engage the spring 23 and move it away from the spool. formed with a collar 3i to engage the spool and y move it away from the end wali i@ of the nousl ing.r This movement is preferably sumcient to move the iiange 25 away from the spring fingers 2l so'that the spool is freely supported-in the housing. At this .time thegate i@ can be turned tobring the openings l@ and i into register so that wire can freely be withdrawn from or wound on the spool. Upon completion of a recording or reproducing operation, the end oi the wire pro1 Jecting through the registering openings i@ and 2i' may be grippedvby turning the gate-id substantially to the position shown in'Figure d so that the wire will be held under slight tension when the magazine is removed from the apparatus.

While one embodiment of the invention has been shown and described in detaii, it will be understood that this embodiment is illustrative only and is not intended as a definition of the scope of the invention, reference being had for this purpose to the appended claims.

. What is claimed isz.

1. A magazine for a, magnetic recording apparatus comprising a 'substantially circular housing', a spool in the housing having a central h'ub portion and end flanges, annular spring means in' the housing engageable with the inner face of one of the flanges, and means in the housing yielding- 1y urging the spool in a direction to cause the l spring means to engage the flange.

2. A magazine for a magnetic recording' apparatuscomprising a substantially circular hous- Preferably the shaft is the flange whichis remote from said one end of the housing. l

3. A magazine for a magnetic recording apparatus comprising a substantially circular h'ousing, a spool in the housing having a central hub portion and en'd flanges, a spring in the housing engaging the spool to urge it axially toward one end of' the housing, and an annular series ci resilient fingers extending inwardly from Ithe housing to engage the inner face of the flange which is remote from said onel end of the housI ing.

4. A magazine for a magnetic recording apparatus comprising a substantially circular heusa ing, a spool in the housing having a central opening, a spool in the housing having a central hub portion and end flanges, a spring in the housing engaging .the spool to urge it axially toward one I ing' to receive a. shaft and having end flanges, a
