1 Claim.

This invention relates to new and useful improvements and structural refinements in ribbon changing implements, and the principal object of the invention is to provide a device of the character herein described, such as may be conveniently and effectively employed during the ribbon changing operation on typewriters, adding machines, or the like, to prevent the previously experienced inconvenience resulting from the handling of the inked ribbon with the fingers.

A further object of the invention is to provide a ribbon changing implement which is simple in construction, which may be easily manipulated and in which the ribbon may be readily applied or removed.

Another object of the invention is to provide a ribbon changing implement which will readily lend itself to economical manufacture and which is otherwise well adapted for the purpose for which it is intended.

With the above more important objects in view and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the construction and arrangement of parts as shown in the accompanying drawings in which:

Figure 1 is a perspective view showing the invention applied to the ribbon;

Figure 2 is a cross sectional view, taken substantially in the plane of the line 2-2 in Figure 1, and

Figure 3 is a perspective view showing the use of the invention in applying the end of the ribbon to the ribbon spool.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a ribbon chan ing implement designated generally by the reference character 5, the same embodying in its construction a blade 6 formed from any suitable material and provided at one end thereof with an enlarged handle portion 1.

The portion 1 may, if desired, be formed with an aperture 8, whereby the implement, as a whole, may be conveniently positioned on a nail, or the like, when not in use.

The remaining end of the blade 6 is provided with an enlarged head 6' terminating in a pointed extremity 9 and is also formed with what may be referred to as a substantially H-shaped slot II].

This slot consists of a pair of spaced parallel slot portions ll, l2 extending longitudinally of the head 6 and an obliquely disposed connecting slot portion l3, as is best shown in Figure 3.

It will be noted that the slot portion I2 is open at one end thereof, as at M, so as to facilitate the threading of the ribbon through the slot, as will be hereinafter more fully explained.

The slot is separates the head 6' into three spaced parallel elements or strips, one of the outside elements indicated at 6 being shorter than the remaining outside element and having a beveled outer end M which is disposed adjacent the slot opening l4 and is substantially parallel to the slot portion l3.

When the invention is put in use, the ribbon to may be threaded through the slot l0 by first being inserted into the slot portion H through the open end l4 and through the connecting slot portion l3, whereupon the ribbon is doubled upon itself, as it were, and is passed through the slot portion H, as illustrated in Figure 1. The beveled end it and the oblique slot portion l3 will facilitate insertion of the ribbon into the slot and it will be found that this threading of the ribbon may be effectively accomplished without the necessity of touching the ribbon with the fingers and after the ribbon has been threaded, the implement may be manipulated so as to withdraw the ribbon from the ribbon carriage l6 associated with the machine.

The end portions of the ribbon l5 are usually provided with an aperture l1, and when it is desired to attach the end portions to the ribbon spool 18, it is only necessary to engage the pointed extremity 9 of the implement with the aperture H and to apply the ribbon to the spool so that the aperture engages one of the detents IS with which the spool is usually equipped.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

In an implement for handling ribbons on typewriters and the like, an elongated handle provided at one end thereof with a head, said head being formed with a substantially H-shaped slot consisting of a pair of spaced parallel slot portions extending longitudinally of said head and an obliquely extending slot portion connecting together the parallel slot portions intermediate the ends of the latter, one of the parallel slot portions having an open outer end, said H-shaped slot defining three spaced parallel elements in said. head, one of the outside elements being shorter than the remaining outside element, said shortened element being adjacent said open slot portion and having a bevelled outer end substantially parallel to the obliquely extending slot portion, whereby said bevelled end and the obliquely 10 Number extending slot portion facilitate insertion of a ribbon into said slot.

EVA MEYER.
