Toallwhom it may concern:

Be 1t known that I, HARRY C. GAMMETE'R,

. .a citizen of the United States, residing at Collinwood, in the county of Cuyahoga and State of Ohio, have invented a certain new and use ul Im )rovement in Ribbon Attachments, of whic 1 the following is a full, clear,

-. and exact description, reference being bad to the accompanying drawings.

The ob ect of this invention is to provide simple and EllGOlJlVU mechanism l'or'noldmg the end of a ribbon to a spool.

'- operat'ors hands.

5 ;T he invention is particularly well ads nod for securing inking ribbons to the s ools of printing or ty ewriting machines. t allows the ribbon to e secured to its spool in a way which does not necessitate the r viling of the The ribbon may also be disconnected from the spool, whenever desired, in an equally simple and cleanly manner.

The invention comprises l)IOt(ll:V the com- "bination of a spool having a longitudinal slot through which the end of the ribbon may pass, and means on the end of the ribbon ada ted to extend across such slot and thus hol the ribbon to the spool. The invention includes also the combina tion with a spool having an opening in its barrel of a ribbon having means adapted to be passed edgewise through such opening and thereafter turned to bridge the opening.

The invention also includes a ribbon orcvided with securing means extending along its end to hold the ribbon squarely to the spool.

Other aspects of the invention will appear from the following more specific description thereof.

"In the drawings, Figure l is a perspective View of the ribbon. spool; Fig. 2 is a perspective View of the ribbon end with my securing 'mernber thereon; Fig. 3-is a cross section on a larger scale through the ribbon spool with the securing member and ribbon in place; Fig. 4 is an enlarged cross section through the securing member and adj acentportion of for example by turning inwardly integral lugs 3) cut out from the heads,'.suoh lugs pass-.

the ribbon.

' As shown in the drawings, A represents the barrel of a tubular 5 001. This spool me be made of sheet metal providedfwith beads B secured thereto n any suitable manner,

ing" into the interior of the barrel and being in either direction brazed to it. Extending longitudinally of the barrel is a narrow slot a t irough which the ribbon and its securing means ma be passed.

C represents the ribbon and D the securing member fastened to the end thereof. This member preferably made of metal and (-1;- tends across the entire end of ribbon. It consists preferably of a sheet of metal bent into the arc-shaped form SllOWH b bending over the edges toward the intermediate portion and curving the whole strip. Before such bending takes place, the end of the ribbon is inserted against theintermediate por tion (Z of the strip and then one edge 0 i bent over on top of the, ribbon, the lihbon being turned back on to the top of this edge, after which me other edge (1 is bent over /o the ribbon. This leaves the ribbon. extending from substantially the mid point of the arcshaped metal head.

As will be seen, the me al head is narrow in, cross section cry point, which enables it to be very easily passed through the slot e in the spool barrel. this slot, this metal head assumes a position extending rol Way from the shit, the ribbon pessi- 1' can it through the slot. It is s cordin l Y onlv nccessarv in mountim the k) u l D 1 ribbon on the spool to tip the metal head on edge drop it through the slot in the barrel it then assumes a position bridging the slot andsecuring the ribbon to the spool. This operation of assembling may thus be accomplished without the necessity of the operator soiling his tinge s. He does not have to directly touch the ribbon at all but can take hold of one of the projecting sides of the metal head.

.Vhen in place, the ribbon may he'wrzmeed out the spool and more is no projection on the outside of he spool to inte fere with the perfect winding oi the When passed tlv'ough ribbon. The metal head extending across the end of the ribbon insures it being held squarely and at all points o the spool. This latter point is of osrtic in importance with wide ribbons such as are nscdjon the znnlti-v graph. l

it will no noticed that the metal strip is arc'shaped in cross section inn n. are of anproximately the radius o? the spool barrel, so that the metal may he snugly on the inner side of the tubular barrel. I

To enable tlie asy removal of the ribbon slot a, so

from the s 001, I provide a transverse opening a in t e barrel, through which a proper tool may be passed to shift the metal head sufficiently to allow it to pass through the slot. I find a very small transverse slot is sufficient for this purpose. As shown, I preferably make two of these slotsextending in opposite directions from the longitudinal v that the metal head may be conveniently released whichever direction the ribbon is extended.

I claim:. V I 1 1. The combination of a spool having an opening and a fabric adapted to pass through such opening and behind an overhanging portion of the spool; and provided with means for holding the end of the fabric within the spool against the inner face of such portion. 2 The combination of a spool having a longitudinal slot and a recess within the spool wider than the'slot and a fabric adapted to pass through'such slot and providedat its end with means occupying the recess for holding the end of the fabric within the spool.

4. The combination of a spool having a longitudinal opening in its barrel and a ribbon provided at its end with a longitudinal head adapted to be passed edgewise through the slot and after such passage turning to bridge the siot.

5. The combination of a spool having a longitudinal slot and a ribbon having a head extending crosswise on its end, said head through such slot and thereafter bridge the slot'on its inner side.

6. The combination of a spool having a longitudinal slot and a ribbon having a head extending crosswise of its end, and projecting in each direction from the face of the ribbon, said head being formed to pass through such slot and thereafter to bridge the slot on its inner side.

8. The combination, with a spool having a longitudinally slotted barrel, the walls defin ing theslot'being relatively immovable and there being an enlarged hollow space behind them, of a ribbon having across its end a thin head formed of a piece of sheet metal bent onto the ribbon and ada ted to extend in o posite directions from t e ribbon so as to )e assable edgewise through the slot and standable widthwise across the slot behind the bar.
