Specification of Letters Patent. i f Application and August 4, 1906.3 smaila. 329,27o.

To all whom, it may concern:

Be it' known that I, NoMA THoMPsoN, la c1t1zenof vthe* United States, residing in lVVashington, District of Columbia, have invented.y certain new and useful Improvements in Type-Writing Machines,' of which the following is a specliication.

This invention relates to ink-ribbons for f type-writing and like machines, and particularly to those machines which use narrow ribbons and have spools with their anges so close together that it is not practicable to insert the fingers between .them to secure the ribbonto the spool-cores. In such machines it has been the practice to provide ycatches upon the cores of the spools to holdthe ends of the ribbon; but heretofore 4it has been necessary to employ a lead-pencil or any Ahandy article to introduce the ribbon be'` tween the flanges and secure it upon the catch, which is a tedious operation and 1n.

volves soiling of the iin ers by the ink upon the ribbon and spool, ,'gIhe ribbon is usually introduced into a narrow passage between the catch and the core, and then 'by manipulation the catch is caused to bitefthe ribbon,

but not securely, so that the ribbon is liable to become detached at times.

The ob'ect ofmyinvention is to simplify the attac and to attach it so securely that all liability of detachment is avoided. I providev the end of the ribbon with a tipl in theform of a metal clip,- which has a hook portion to lengagel the catch upon the s ool, and I also use said clip for thepurpose o holding the end of the handle, which extends from the clip along the ribbonb'ut separate therefrom and is of such length thatit may be employed by `the operator to conveniently insert the hook within the spool and attach itto theribbon-holding device thereon. The handle is preferably so longthat it-,extends well outside of the spool when the hook is in position upon the core or catch of the spool,and the handle is separate from the ribbon, vso that it is unnecessary in manipulating the former to soil the hands by contact with the ribbon. The handle may be inthe form of a plate'extending along the ribbon, an'd it is sufliciently flexible to, wind readily around the spool-core within the coils of the ribbon. When detaching the ribbon, the handle may be straightened out `(or, if reent of the ribbon tothe spool the hook. Fig. 4 showsanopposite view of the Fig. 3 device. j The ribbonspool (seen at Fig, 1) ,is Vof the 'type commonlyemployed on the Underwood type-writing machine and comprises flanges 1 and 2, which are quite close together, and a core 3. In the latter is rovided the usual pin 4, upon which to catcli) pin is usually provided with teeth, as'illusplate 6, having ears 7 folded over the end of having an extension which is folded down to form a hook 8. Clamped upon the ribbon raf-,emga Nev. 6,1906. i

.trated; but these maybe omitted. *Uponl silient, it vmay recover its normal straight the ribbon. Said the ink-ribbon lI secure a clip comprising a V the ribbon and clamped thereto, said plate by means of the ears 71s one end offa handle 9, which is preferably in the 'form of a thin celluloid blade extending along the ribbon but separate therefrom, so that-1t can be mathe ngers. l

In attaching the ribbon the free end ofthe handle 9 is picked up by the o erator, and the .handle is us'ed like a 'needle,}being thrust through the aperture 1 0, between the pin 4 and the core 3 of the*s 001. The handle is then drawn-back to catc the hook 8 upon the pin 4, as at Fig. 2, whereby the ribbon is securely connected to the spool, the operation being 'extremelylsimple and speedy. The handlel 9 'is preferably of sufficient length to extend well outside of the spool when'the hook is in position upon the pin `4, as' seen at Fig. 42, and 1s preferably secured upon-the other side' of the ribbon from the hook, as at Figs. 3 and pulated without touchingthe ribbon with 4.) Owing toits iiexibility, the handle will readily wrap around the spool-core within the coils of ribbon and will prove convenient' 'when the ribbon is unwoun'd for detaching the llatter from the spool. 7 f

Having thus described my invention, I

claim* f 1. Anali-ribbon having secured 'upon its IOO in the'tspol, said' handle being' sufficiently Aleizble*,to enable-it toccoil aroundthe core '-.ofthegspols 2.v A type-Writer yribbon provided uipon its ,end withfa tip', and having a thin vexijble handleattached to the end `of said-tip -and eX- nding aiongtherbbonand separate thereom.'` 4 l l v3.' typefwriter ribbon provided u on its end with a tip, and having a thin exible i handle attached to the end of said tip and extending along the ribbon, said ti being in the form of a sheet-metalI clip wh'c secures the end of the handle to the-end of the ribbon, and which also has-a hook portion to catch upon the corresponding -part of the spoolcore.
