itnsne'cessdr te fee'd a ribbon from-a; roll carried onlthe machine: Inasmuch as the invention resides in: the novel ribbon roll supporting equip ment em'd inthe: cdmhihaitibn of Suc'li equipmentwith other: parts which themselves may be of s conventionai eonstruetio'n; the drawings show the known or conventionai' structure only par tially:

Included in" the illustrated known cons-truc tienz is a; ty ewriter 11min:firemen on which ectflrr i'aige enerally designated B is mounted for letterspaoi'ng and return travel. The ceirriage 15 corr'iprise's spaced-end pleftes I and 2' connected by carriage frame members orcross ieces; one of 'which issh'own at}! as beihg' conhected to arms 3 rs 5 and 6 between the end plates l and 2 serve to support a series or sheaf of work sheets I led from a supply at the rear of the machine forwardly over the carriage B where they are passed in front of a platen 8 mounted on end plate bosses, one of which is shown at 9.

Ribbon mounting means generally designated R constructed in accordance with the invention, is mounted at the rear of the typewriter so as to be supported mainly on the frame A for travel in the direction of carriage movement, the means R being adapted to be connected releasably to the carriage so as to travel to and fro with it during letter spacing and return movements. The ribbon mounting means R shown by way of example has a capacity f nine ribbon rolls r r r r r r, 1, 1' and r each of the rolls being accommodated in a separate chamber or compartment. Ribbons may be led from each of the rolls but Figures 1 and 2 show only three ribbons, namely those designated R R and R" as being extended respectively from the rolls r 1- and r for being guided and fed along the platen writing line in a manner presently to be described. Figure 4 shows the same structure as is illustrated in Figures l and 2, but it will be observed that in Figure 4 ribbons R R and R are extended from the rolls r 1' and r It will be understood that ribbons may be fed from all of the rolls 1' r or from any selected rolls. Any ribbons extended from the rolls r r and r are passed around a guide roller I0, journaled on a bracket l l secured to the carriage end plate I. Ribbons extended from all or any of the rolls r 1 and r are passed around a guide roller l2, and ribbons extended from any or all of the rolls r T and r are passed around a guide roller I3.

Strips of ribbon extending from the ribbon mounting means R and around the rollers I8, l2 and. 13 are guided and fed along the writing line of the platen 8 by suitable mechanism such, for example, as the ribbon guiding and feeding mechanism disclosed in the patent to Myers and Handley 1,890,547. As shown in Figure 5, ribbons R and R trained around the rollers l0 and I3 extend to a front guide roller [4 journaled on the bracket H and, after passing around the roller 14, extend along the writing line in front of the platen 8 for being interleaved with the work sheets I in a known manner.

Mechanism for feeding the ribbons along the platen writing line includes a hand lever 15 pivoted as at IS on the bracket H. Rockable with the lever I5 is a cam I! adapted to cooperate with suitable mechanism, for example, mechanism as shown in the aforesaid Myers and Handley Patent 1,890,547, for pulling th ribbons along the platen writing line toward the operators right, that is, toward the left as viewed in Figure 5. The ribbons may be placed under tension in addition to that incident to feeding off of the ribbons from the rolls in the ribbon mounting apparatus R. For this purpose mechanism similar tothat shown' in the Degener Patent 1,853,761 may be provided. The illustrated mechanism includes a pack of leaf springs 18 mounted on the bracket II. The ribbons are passed through different pairs of adjacent springs of the pack which press upon the ribbons and tend to retard passage of the ribbons through the pack. When the operating lever I5 is rocked counterclockwise as viewed in Figure 5, the cam ll actuates a follower roller 19 to rock a lever 20 pivoted as at 2| on the bracket II. This pulls on a link 22 and spring 23 to rock a lever 24 which is pivoted on an ear 25 extending from the carriage end plate I. A

cam 26 fast with the lever 24 is thereby rocked against a spring arm 21 mounted as at 28 on the end plate -I, thereby pushing the free end of the arm 27 against and compressing the pack of springs l8 so as to impose a frictional drag on to the operators right, that is, to the left as viewed in Figure 5.

In accordance with the present invention a roll of ribbon is fed from the means R in a novel and simple manner such that inertia overthrowing of the ribbon roll is checked so as to prevent unwinding of ribbon in excess of that actually fed by operation of the lever l5, thereby eliminating danger of producing unnecessarily long and slack stretches of ribbon which would be apt to become tangled and torn. A particular feature of the invention is that the ribbon roll is not journaled to rotate about a fixed central axle in the usual way, but is rested bodilyon two spaced portions of a support in the nature of a pan, the friction between the pan and the peripheral surface of the roll preventing unwinding rotation of the roll except that which is due to positive pulling of the ribbon by operation of the feeding lever 15.

The ribbon mounting means R shown in Figures 1 to 5 includes a receptacle or the like provided with a bottom comprising a single sheet of material bent or otherwise formed to a zig-zag shape soas to provide three V- shaped pan bottoms 33, 34 and 35 extending in the direction of carriage travel. The receptacle is provided also with outer sides 36 and 3'! and with partitions or inner sides 38, the arrangement being such as to provide nine separate chambers or compartments each of which receives one of the rolls 1' T The roll mounting structure R is equipped at its right hand end, as viewed in Figures 1 and 2, with a vertically extending transverse wall part 39 formed with three guide slots 40 disposed respectively in line with the three sets of aligned co-planar pans. The three ribbons from each aligned set of ribbon rolls pass through the guide slot 40 in mutually superimposed relationship, as shown in Figure 2. A horizontal guide pin 4| extends transversely between the walls 36 and 31 for guiding ribbons led off the rolls r 1 and r and a similar guide pin 42 extends between the outer sides 36 and 3'! for guiding ribbons fed off the rolls r 1 and T The pan structure R may be provided with a removable cover 43.

Each of the pan compartments includes a V- shaped bottom, for example, the bottom 34, on which the roll 1' is supported. The sole vertical support for the roll is provided by resting the roll periphery directly upon the spaced leg portions of the V-shaped bottom so as to engage them frictionally whereby free rotation and inertia overthrowing of the roll is prevented. When the operating or feeding lever l5 and the associated feeding mechanism is operated the ribbon R will be pulled upon with suflicient force to cause the roll 1' to slip on the supporting V-shaped pan bottom. thereby allowing ribbon R to be fed along the platenprinting line as required. However, the frictional resistanceto turning of the roll 1' is sufficient to'bring the roll to rest as soon as the positive pull exerted by thefeeding mechanism is discontinued. Consequently, even a sudden or jerky operation of the feeding mechanism will not cause the roll r to turn any more than the amount necessary to release a-length of ribbon equal to that taken up by the feeding mechanism. There will be no inertia overthrowing of the roll and no slackness will be introduced in the length of ribbon 1'1. extending from the roll r to the feeding mechanism. It will be understood, of course, that the other rolls whose peripheries frictionally engage the associated V- shaped pan bottoms are retarded in a similar way so as to prevent inertia overthrowing, The retarding or overthrowing preventing action due to frictional contact of the rolls with the associated pan bottoms decreases as the masses of the rolls and their inertia decrease, so that the retarding action will not be unnecessarily great at any time.

In accordance with a further feature of the invention the roll mounting means R is sup-ported on the main frame A for travel with the carriage and is adapted to be connected releasably to the carriage in a manner permitting tipping displacement of the pans to positions in which insertion or removal of rolls is facilitated. In the form shown, a bracket 44 is provided with cars 45 secured by screws 46 to ears 4! on plates 48 attached to ends of the main frame A by screws 49.. A rail 58, which is circular in cross section, is fixed to the bracket 44 and extends longitudinally behind the main frame A and under the rear part of the carriage B. Depending from the .pan structure R are two spaced legs 5| secured to the pan structure by bolts 52. Pintles 53 carried respectively by the legs 5| serve to journal grooved rollers 54 which run on the track 50 whereby the weight of the pan structure R is carried on the framesupported rail 58 in a manner to permit the pan structure R to move in the direction of carriage travel. In order to prevent the rollers .54 from being displaced from the rail 58, the legs 5! are extended downwardly and are turned inwardly to provide retainers 55 projecting under the rail .50.

The mounting of the structure R on the rail 50 by means of the rollers 54 held in place by the retainers 55 enables the pan structure R to swing angularly about the rail 50 from the operative or working position shown in full lines in Figure 4 to the position shown in dotted lines in Figure 4 wherein the roll compartments .arefaced away from the machine, thereby facilitating the insertion of rolls in the pans or their removal therefrom.

Means are provided for releasably connecting or securing the pan structure R tothe carriage B in the normal upright or working position shown in full lines in Figure 4. The carriage end plate I is formed with an ear 56 equipped witha headed stud or keeper 51. A latch bar 58 pivoted as at 59 on the pan wall 3'! is provided with a recessed latch end portion 60 adapted to be engaged releasably with the keeper 51. A prong 6| struck out rearwardly from the pan wall 31 extends behind the outer end portionof the latch bar 58 to hold it against bending or springing and to maintain it close to the side 31 for proper engagement with the keepeer 51. When the latch bar 58 is rocked counterclockwise from the position shown in Figure-2, the recessed latch end '60 will be moved to the dotted line position shown in Figure 2 so as to be released from the keeperfif.

The carriage end plate 2 is formed with an ear 62 on which is mounted a headed stud-or keeper 63. A latch bar 54, pivoted as at 65on the pan side 31, is formed with a recessed latch end 66 adapted to engage the keeper 63. Aprong 61 struck rearwardly from the pan side-37 guides and provides lateral support for the latch bar 64. When the latch bar 84 is rocked counterclockwise from the position shown in Figure 2 the recessed latch end 66 will be released from tli'e studor keeper -63. I Y

Normally the latch bars 58 and "64 are held in their operative or latching positions shown in full lines in Figure 2 so as to maintain the pan structure R in its working position connected tofthe carriage as shown in full lines in Figure 4. For this purpose a spring 68 is interposed 'betwee'n'a stud 69 mounted on the inner end of the'latch'b'ar 58 and a stud 75 mounted on the inner endof the latch bar 64. In order that the latch bars 58 and 64 may be moved simultaneously toreleased position a single operating lever "l I, pivoted as at 72 on the pan side '31, is adapted to rock both latch bars against the urge of "the spring 68. The lever H is provided with a fingerpiece l3 and a cam arm 14 which extends between the inner ends of the latch 'bars 58 and 5413 s shown in Figures '2 and 3. When the lever H is rocked clockwise as viewed in Figure '2 the cam arm 14 moves the inner ends ofthe latch bars 58 and 64 respectively downwardly .and upwardly so as to rock both latch bars count'erclockwise to the released positions shown indotted lines. When the panstrueture R has been thus released or disconnected from the carriage B it can be swung angularly .about the rail .50 to the position shown in dotted lines in Eigure =4 with the open tops of the pans facing away from the back of the machine whereby rollsmay easily .be inserted in or removed from the pan compart: ments.

When a roll has become almost entirely unwound or exhausted, requiring its replacement, it will be of small diameter and will be housed well below the top of the pan sides 36, .37 and-38.. In order to assist in removing the. small rolls which otherwise would be rather inaccessible, the pan outer side 36 is formed with vertical slots'fi, I6 and 11 and the partitions or inner pan sides are formed with slots 18. If it is desiredto remove an exhausted roll, for example, the roll r a simple instrument such as a pencil or stylus may be inserted in the slot 11 and projected into the opening in the hollow roll or roll core and the roll then lifted high enough to permit its-being grasped easily and then removed completely from the pan. If it is desired to remove ayro'll rother than one adjacent the pan side 38, for example,- the roll r the instrument may be extended through the slot 16 and the slot 78 and projected into the opening in the center of the :roll after which the roll is lifted as previously described. This may necessitate passing the instrument through the center of the roll 1' also, but vno harm will be done because when the rolls '1 and :1 are lifted together only the roll r need be grasped'and removed completely. Figure 6 shows a modified constructioniin which only a single longitudinal row of compartments or pans is included in the roll supporting pan structure S. Although a cross section through only one pan [9 or compartment is shown it will be understood that a longitudinal section would show a plurality of aligned pans 19 with v-shaped bottoms as shown in Figure 2. The pans include a common bottom member 80 and sides BI and 82, the side 8| being secured by bolts 83 and 84 to ears 85 and 86 on the carriage B. In order to relieve the carriage of most of the weight of the pan structure S, the latter preferably is supported by two spaced legs, one of which is shown at 81, each of the legs being equipped with a pintle 88 on which is Journaled a roller 89 arranged to run on a rail 90 mounted on a bracket 9| secured to the main frame A. Retainers, one of which is shown at 92, are formed on lower extensions of the legs 81 so as to project under the rail 99 and prevent lifting of the pan structure 5. One of the rolls r is shown supported in an associated V-shaped pan and ribbons from this roll and the other rolls, not shown, are indicated at R as passing through a guide 93 extending rearwardly from the top of the pan side or wall 8|.

The rear wall 82 of each of the pans included in the structure S is formed with a slot 94 through which an instrument such as a pencil indicated" at 95 may be extended for lifting a small diameter roll to a position in which it may be grasped conveniently for being removed.

The apparatus disclosed embodies the invention in a preferred form, but it will be understood that changes may be made in the construction and arrangement of the parts without departing from the invention as defined in the claims.
