."T'YPE-WR' 'N Q EITI-RIBBONSPOO i I srncrrrenrroiv forming part of Letters Patent No. 605,032, dated May 31, 1898. H 1 Application filed February 11, 1890. Seria1No.340,0'55. unmade.)

Be'vit known that I, -HENRY U NZ, a citizen of the United States, residing at Philadelphia, county of -;Phjladelphia,- andStat-e of Pennsylvania, have invented a new and use.- ful Improvement in RibbonSpools for Type- Writing Machines, of which the following is.

a full, clear, and exact description, reference being had to the accompanying drawings,

which form a part of. this specification. *In the type-writer the type strikes at a certain point on th eplaten, and therefore strikes i always at a certain point in the inking-ribbon.

As ordinarily constructed, therefore, if the inking-ribbon be of some width, pnly a certain portion of it is useful in .type-writing,"and when it becomes worn orthe ink' exhausted it requires a new ribbon.

My invention has for its object an improved construction whereby the ribbon spools carrying the inking-ribbon may be given a lateral movement, so that different portions of the inking-ribbon may be presented to the action of the type, and as one portion of the ribbon becomes worn the rib? bon may be shifted, so as to present a different portion of the inking-ribbon to the action of the type, and thus thewhole width of the ribbon may be used in the operation oftype writing. l p

In the drawings, Figure 1-:is a perspective side view of ribbon-spool, driving ratchetwheel, and ribbon-spool supports. Fig. 2 is a detached perspective View of ribbon-spool,"

shaft,'and. ratchet-wheel with spool in its most shifted position. Fig. 3 is a detached perspective view of'same, showing spool in an intermediate shifted position. Fig; 4 i's'a detached perspective view of same, showing on the shaft. Fig. 5. Fig. 7 is an end view of ribbon-spool.

spool in its normal position. Fig. 5 is a view showing ratchet-wheel, ribbon-spool, shaft,

and retaining-spring for retaining the spool Fig. dis a sectional view of A is the ribbon-spool shaft, supported be,- tween the fixed bearing a and the spring-arm 01., Upon this shaft isthe ratchet-wheel 13,

provided with the projecting pin b.

0' is a-spring secured upon'the shaft, as

shown in'Figs. 5 and 6, D is the ribbon-spool, which is slipped overt-he shaft and held so wh eel are the steps or projecting surfaces old. The spool is normally in such a position that the projecting pin 1) rests against the surface of the head of the ribbon-spook v E is the ribbon carried by the ribbon-spools. When for any reason it is desired to shift the ribbon-spool and the ribbon, the ribbon-spool is shifted and turned upon the shaft until the pin b rests against'either of the projections d or (1, according to the extentof shift desired, by-which it is retained." By this means I am enabled to so shift the ribbon-spool that I can cause the type to act upon different parts of side of' the machine.

as to rotate with it by means of' the spring C, 1 pressing against the surface of said spool. Upon the end of this spool toward theratchet- Having nowfullydescribe'd my invention,

what I claim, and'desire to protect by Letters Patent, is

1. As a new article of manufacture, aribhon-spool provided with a step or projection adapted to coact with a fixed stop on the machine for locating the position of the ribbon on the spool with reference to the point of im pact of thetype; 2'. As a new article of, manufacture, a ribbon-spool provided with two or more steps or fixed step or projectionon the machine to locate theposition of the ribbon with reference to the printing-point of the type and to vary the position of the ribbon with reference to said printing-point.-

' 8. Ina type-writing machine, in combination, aribbon-spool provided with a step or projection at its'head, and a stop upon the projections at its head, said 'stepsliprojecting -difierent extents and adaptedto-coactwith a v machine adapted to rest upon the step or projection to locate the position of the ribbon with reference to the printingpoint of the type and tovary the position of the ribbon withvreferenee to said printing-point.

4. In a type-writing machine, in combination, a ribbon-spool, provided with two or more projections or steps at its head, said steps projecting different extents, and a stop upon the machine adapted to rest against the steps upon the ribbon-spool.

5. In combination, a ribbon-spool shaft, a disk upon said shaft, a pin projecting from said disk, at ribbon-spool upon said shaft, and a projection or step upon the head of said spool, adjacent to the said dis:

6. In combination, a ribbon-spool shaft, a disk upon said shaft, a pin projecting from said disk, at ribbon-spool upon said shaft, and two or more projections or steps uponthe head of said spool, adjacent to the said disk, said steps projecting different extents from the body of the head.

7. In combination, a ribbon-spool shaft, a driving ratchet-wheel upon said shaft, a projection from said ratchetwheel, a ribbonspool upon said shaft anda projection or step upon the head of said spool adjacent to the said ratchet-Wheel.

81 In combination, a ribbon-spool shaft, a driving ratchet-wheel upon said shaft, a pin projecting from said ratchet-wheel, a ribbonspool upon said shaft, and projections or steps upon the head of said spool adjacent to the said ratchet-wheel.

In testimony of which invention I have hereunto set my hand.
