TYPE-WRITER RIBBON ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 26, 1907.

' Application filed February 28.1907- Serial No. 359,756.

- California, have invented certain new and useful Im rovements in T e-Writer Ribbon Attac ents; and L do eclare the following to be a full, clear,'and exact descriptionxof the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

' This invention relates to improvements'in typewriters and particularly to the ribbon I attachments thereof.

j My object is to produce a means for attaching and detaching ribbons to and from typewriters without annoyance or delay or soiling the operators. hands. Also to produce a reel attachment which. Will permit of cleanliness in. changing old .and worn out ribbons .fornew and for exchanging one color or style 25. of ribbon for another, or for removing the ribbon as in mimeograph work. This object I accomplishb means of a removable flange on the reel an a slot split in the hub for receiving the ribbon; also by such other and further construction as will appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several-views.

Figure 1 designates the ribbon movement ofa typewriter showing my improved device installed thereon. Fig. 2 is a top plan view of a ribbon guide. Fig. 3 is a front elevation of said-guide, while Fig. 4 is a side elevation Fig. 5 is a top lan view of a ribbon reel cup. Fig. 6is a si e elevation'of said on Fig. 7 is a top plan view of a ribbonree spindle or hub. Fig. 8 is a side elevation of the same. Fig. 9 is a top plan view Fig. 10 is an end clcvation of-a reel. Fig. 11 is a top plan view of a removable reel flange. Fig. 12 is a side 'elevation of a pair of tweezers.

Referring to the numerals on the drawing 1 designates a fragmentary portion of a type-writer showing the ribbon attachment thereon.

2 designates the reel cup formed with a passageway 3 for the passage of the ribbon out of said 0111),81 guide member being formed at the inner end of said passage, said guide 'structed as follows:

member being,composed of a strip of steel 4. secured to sideof cup and extending upward and having a bent over ortion Sleaving a space therebetween for t e insertion of the rlbbon, said guide being so arranged as to lead the ribbon out from the cup at an angle of thirty degrees outward from a right line drawn from extremityof radius, from center of cup to point of lead from cup. Arranged in said cups are my improved reels con- 6 designates the hub or spindle having a lower fixed flange 7 attached thereto. Said hub is'provided with a slot 8 cut in one side thereof the upper end of said slot being open for the purpose as will appear. upward from the to thereof for the purpose of receiving a reel as will appear. In the top of said hub 6 are struck in V-shaped grooves 10 the same extending radially in respect to the center of said hub. 11 designates a removable flange rovided with a slot 12 adapted to permit t 1e said flange to slip under the flange 9, said slot 12 enlarging into a slot 13 for the purpose of permitting the insertion of the flange over the flange 9 to permit the same to be slipped thereunder as escribed. Outward from the slot 12 are struck out V-sha ed spring clips 14 adapted to engage with tie grooves 10' thus holding the flange on the said hub 6. I also provide a ribbon guide for guiding the ribbon in front of the type at the oint of contact, consisting of a main stain ard 16, the same having a bifurcated end '17, the bifurcations thereof being provided with arms 18 having bent over ends 19 forming guides for the ribbon. The construction permitsof an easy adjust ment of the ribbon in the shortest possible time.

In using the device when it is desired toexchange an old ribbon for a new one the Said hub also has a flange 9 held slitted portion is inserted in the slot 8, the

other remaining outside, thus forming a lock for said ribbon, B., or a small piece of metal may be attached to the end of the ribbon having a bent ortion to facilitate inserting the ribbon in t e slot 8 and rovent its slipping through the slot 8. he flange 11 is then inserted under the flange 9 as-described, the spring clips 14 fitting into the grooves 10 and thus locking said ilaiwe on the hub. To

msert the ribbon in the ribbon guide, Fig. 3,.

it is only necessary to place 'a fold of the rib-,

bon over the bifurcated'end 17, with a penoil, etc., when u on, turning one of the reels proper place unthe ribbon will s ip into its I The" ribbon" guides described irnpart an even and free motion to the ribbon. Twezers 20 may be used in handling the ribbon;
