Nov. 27,'1962 E. D1 Luco 3065837 RIBBON sPooL HoLDER Filed Nov. 22, 1960 INVENToR. fuGE/VE D1 Luca AMW/if. BMW

ATTURNEY Stres 3,06s,837 noN sPooL HoLDER My invention relates generally to inked ribbon holders, and specifically to an inked ribbon spool holder for the insertion and Withdrawal of inked ribbon from type- Writers, teletypewriters, computers and like machines, without touching the ribbon.

Many inked ribbons are provided with a protective covering at the exposed end portion of the ribbon, or at the center of the ribbon when partially wound on two spools, to prevent the fingers from being soiled by touching the exposed ribbon while inserting it into a machine. However, in every instance, the spool on which the ribbon is wound must be touched when inserting or withdrawing the spool from a machine. It is extreinely difiicult to touch the ribbon spool without touching the ribbon, and it is equally difficult to avoid ink-soiled areas on the spool itself.

Therefore, it is among the objects and advantages of my invention to provide a ribbon spool holder which is adapted to facilitate insertion and withdrawal of the ribbon spool without touching the ribbon or the spool.

Another object of my invention is to provide a ribbon spool holder in which the ribbon spool is releasably held within a holder by latches which engage the top flange of the ribbon spool las the spool is inserted into the holder.

A further object of my invention is to provide a ribbon spool holder which may be pressed downwardly over a ribbon spool mounted in a machine, grasping the spool by means of latches on spring-loaded levers, and thereafter to remove the spool of spent ribbon tightly secured in the holder.

Yet another object of my invention is to provide a ribbon spool holder which may be so inexpensively fabricated of some material, such as plastic, that it may be sold as a protective package with the ribbon spool in it, and disearded when the exhausted ribbon is removed by it.

These objects and advantages as Well as other objectsV and advantages may be achieved by my invention, one ernbodiment of which is illustrated in the drawings in which:

FIGURE 1 is a view in perspective showing my ribbon spool holder positioned above the ribbon spool receptacle on a typewriter.

FIGURE 2 is a side elevational view of my ribbon spool holder.

FIGURE 3 is a Vertical sectional view thereof.

FIGURE 4 is a 'bottom plan view thereof.

FIGURE 5 is a perspective view of a spring for operating a lever.

FIGURE 6 is a view in perspective of a lever which may be pivotally mounted on my ribbon spool holder.

Referring now to the drawings in detail, my ribbon spool holder comprises an inverted cup-shaped housing 11 having a circular top 12 and an annular, generally perpendicular, depending flange 13 formed integrally thereon. The top 12 is provided with a central hole 14 to facilitate the discharge of .a ribbon spool in the event that friction retains it within the housing 11. 'Ihe top 12 is also provided with a pair of slots 15, 16 positioned on the same diameter at opposite edges of the top 12. The annular flange 13 is provided with a pair of diametrical slots 17, 18 communicating with the slots 15, 16 respectively. The slots 17, 18 extend from the top 12 downwardly through the flange 13, terminating however above its bottom edge. The flange 13 is also provided with a Patented Nov. 27, 1962 ribbon slot 19 extending upwardly from its bottom edge, terminating at the top 12.

The top 12 is provided with opposed ears 20, 21 arranged in pairs on opposite sides of the slots 15, 16 respectvely. Each of the ears 20, 21 is provided With a hole 22 to accommodate a shaft 23. Pivotally mounted on each shaft 23, is a lever 24; each lever 24 is provided with a pair of ears 25, 25 each having a hole 26 therein to accommodate the shaft 23 on which the lever 24 is mounted. The lever 24 is also provided with a latch 27 that pivots inwardly and outwardly through the slots 17 and 18 in the flange 13. The latch 27 is provided with a shoulder 28 to engage and hold the bottom of the top ilange of a ribbon spool and to retain it within the housing 11. The latch 27 is also provided with a cam-surface 29 lbeneath the shoulder 28 to engage the top flange of the ribbon spool, deflecting the lever 24 outwardly, as the holder 11 is inserted over the spool, until the shoulder 28 can pivot under the top flange.

A spring 30 is mounted on each shaft 23 between the ears 25, 25 on the lever 24. The spring 30` normally urges the lever 24 to pivot about the shaft 23 urging the latch 27 inwardly toward the center of the housing 11. Inward movement of the latch 27 is limited v`by engagement of the ears 25, 25 with the top 12.

In operation, a ribbon spool carrying a fresh inked ribbon is inserted into the holder at the factory. The diameter of the ribbon spool holder is slightly greater than the diameter of the spool. As the spool is inserted into the housing 11, its top flange engages the cam-surface 29 on the latch 27 deflecting the lever 24 outwardly in opposition to the spring 30. As the flange of the spool passes the shoulder 28, the latch 27 snaps inwardly under the influence of the spring 30 and the shoulder 28 engages the bottom surface of the top flange of the ribbon spool thereby retaining it in the housing 11.

To insert a ribbon spool in a machine such as a type- Writer, the holder having the ribbon spool contained therein is positioned over the ribbon spool spindle of the machine. The holder is moved downwardly so that the shaft passes through the ribbon spool. Finger pressure is applied to the portions of the levers 24, 24. The levers 24, 24 are thereby pivoted to dsengage the shoulders 28, 28 from the topmost flange of the ribbon spool and the holder 11 lifted upwardly, leaving the ribbon spool mounted on the shaft in the machine. In this manner, a ribbon spool may be inserted in a machine Without the fingers ever touching the ribbon or the spool.

In some instances, it may be desirable to employ a ribbon wound on two spools. In these cases, a separate holder is employed for each spool, With the ribbon joining the spools together passing through the ribbon slots 19, 19 in the flanges 13, 13. The same procedure as set forth above is employed to insert simultaneously each spool in the machine. The exposed ribbon joining the spools together may then be inserted into the ribbon carrier on the machine. 'Ihe ribbon may be provided with a protective sheath to permit finger manipulation Without touching the inked surface of the ribbon.

The ribbon spools may be removed from the machine by inserting the holders into the machine over the spool. As the holder is pressed downwardly, the topmost flange of the spool will engage the cam-surface 29 on the latch 27, deflecting the lever 24 outwardly, until it passes the shoulder 28. The latch 27 then snaps inwardly under the influence of the spring 30, and the shoulder 28 engaging the bottom of the top flange of the ribbon spool. The holder 11 is then withdrawn upwardly, the ribbon spool firmly retained therein.

The ribbon spool holder may be fabricated of some suitable inexpensive material such as plastic. The holders may be sold with the ribbon spools contained therein as a sales package. After the spool has been inserted into the machine, the holder is retained for use in the removal of the ribbon spool after the ribbon has been spent. The holder with the spent ribbon spool contained therein may be discarded so that the hands need never touch the ribbon or the ribbon spool.

The foregoing description is merely intended to illustrate an embodiment of the invention. 'Ihe component parts have been shown and described. 'They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention; these substitutes are conternplatedas being within the scope of the appended claim, although they are not specifically catalogued herein.

What is claimed:

A ribbon spool holder comprising a generally circular slotted top, having a pair of dia metrically opposed slots extending inwardly from opposite sides of the peripheral edge of the top.

a depending annular slotted flange on the top, having a pair of opposed, generally parallel slots extending downwardly from the top and intersecting with the slots in the top,

the top and annular flange defining a housing for a ribbon spool, the housing being open at the bottom,

a pair of levers pivotally mounted on the housing for movement in each of the slots,

a latch on each lever in the housing,

a shoulder on each latch engageable with the ribbon spool in the housing,
