SPECLFCATION forming part of Letters Patent No. 716,701, dated December 23, 1902.

Application filed October 30,1901.

To @ZZ whom t may concern:

Beit known that LGARL Gaeninnsoma citizen of the United States, and a resident of Springlield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements'in Type-Writing Machines,of which the following is a specification.

The object of my invention is to provide simple and'efficient means for effecting a varying lateral movement of the inking-ribbon, as well as a longitudinal movement thereof, so as to use the ribbon both widthwise and lengthwise.

To this end my invention consists in the novel features of construction and arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a cen-` tral vertical longitudinal sectional view from front to rear of a type-writing machine embodying my invention. Fig. 2 is a horizontal sectional view of the same, taken immedi-` ately below the top plate. Fig. 3 is a transverse vertical sectional view of the machine, taken at the line X in Fig. 1 and looking toward the rear of the machine, but omitting some of the parts shownin Fig. 1 for the sake of clcarness. Fig. 4 is a detail perspective view of the movable ribbon-guide. Fig. 5 is a detail perspective view of one of the yokes which form a pair of parallel links for moving the ribbon-guide. Fig. 6 is a fragmentary perspective view of portions of three type-bars and their projections. Fig. 7 is a fragmentary perspective view of a modification.

In the various views parts are omitted and broken away to better illustrate other parts of the construction.

1 is the general framework, 2 the top plate, and 3 the key-levers, which are pivoted at 4 45 and provided with hoger-keys or buttons 5.

A sublever 6 is pivoted to each key-lever 3 at 7 and is slotted at S in order to embrace the fixed fulcrum-rod 9. The upper end of each of these levers 6 is pivoted to a for- Serial No'. 80,513. (No model.)

Wardly-extending link 10, as indicated at 11, 5o the forward end of each link being in turn pivoted to a type bar or carrier 12, as indicated atY 13. These type-bars are pivoted upon a curved rod 14, supported in a segment 15, which is slotted radially to accom- 5 5 modate the hub ends of the type-bars. EX- tending beneath the various key-levers 3 is a universal bar 16, which is connected tolinks 17, that in turn are connected to arms 18, which are united to a bar 19, that in turn is 6o secured to a crank-arm 20, pivoted at 21 and supporting the feed-dog carrier 22, having the usual feed-dogs 23, that cooperate Witha feedwheel 24, that is connected to a shaft which turns in a bearing 25, that is secured to the 65 top plate of the machine, as indicated at 26. The opposite end of the shaft, to which the feed-Wheel 24 is operatively connected, has secured thereto a feed-pinion 27, which coperates with the feed-rack 28, that'is carried by 7o a carriage 29, in which a platen 30is mounted. The carriage 29 is connected to a springdrum 31 by means of a band 32, so as to move the carriage in the direction of its feed. The

.revolving spring-drum 3l is operatively con- 75 nected to a bevel-pinion 33, which meshes with a cooperating bevel-pinion 34, carried upon a longitudinally-extending shaft 35, which is provided with bevel-pinions 36, which are adapted to alternately mesh with 8o cooperating bevel-pinions 37, each of which is connected to a shaft 38, that carries at its opposite end a driving-pinion 39, that cooperates with a pinion 40 upon the shaft of one of the ribbon-spools 41. These ribbon-spools 85 4l are mounted upon opposite sides of the machine, and `the ribbon 42 in passing from spool to spool extends through apertures 43 in the bifurcated movable ribbon-guide 44. The movable ribbon-guide 44 .is provided 9o with bent and rearwardly-deflected ears 45, which are perforated, as indicated at 46, for pivotal connection with parallel links 47, the said pivotal connection being indicated at 4S. The parallel links 47 are preferably 95 formed of two yokes of the general construction represented in Fig. 5 of the drawings.

These yokes may be pivoted at to an arm 49, depending from the top plate 2. One of the yokes is provided with an upwardly-extending arm 51, to which a rod 52 is pivoted at 53. The opposite end of this rod 52 is secured to a segmental bar or plate 54, which is provided near each end with a rod 55,that is pivoted at 57 to an arm 56, whose lower end is pivoted at 59 to a stud 5S, depending from the top plate.

Each of the type-bars 12 is provided with a lug or projection 60, preferably formed integral with the stock of the type-bar. These lugs or projections 60 project to dierent eX- tents from the upper or inner edges of the different type-bars, asindicated in Figs. 1, 3, and 6 of the drawings, and they are each adapted to contact with the plate 54 when the typebar has nearly completed its printing stroke and to move the plate 54 rearwardly. orin the direction of the arrow in Fig. l of the drawings. The movement thus imparted to the plate 54 will force the rod 52 rearwardly, thereby causing the lower frame 47 to be rocked on its pivots 50, thus elevating the movable ribbon-guide 44 to bring the ribbon into the path of the type on the type-bar before it reaches the printingpoint. The weights of the ribbon-guide and the parts connected thereto are suiicient to restore the 1 ribbon-guide to the normal position, (illustrated in Fig. 1,) thus conveying the ribbonguide to the inoperative position to expose the last written character on the paper; but

a returning-spring may be added, if desired.v

It will be understood that the projections 60 on the differentsegmentally-arranged typebars will force the plate 54 rearwardly to different extents by reason of the fact that the projections on the different bars are of different lengths, and hence different type-bars Will cause the ribbon to be lifted or moved transversely of its length different distances or to varying extents, and thus insure the use of the ribbon crosswise as well as longitudinally. It will likewise be understood that While the lateral movements of the ribbon may be varied by the operations of the dierent type-bars the relationship of the parts is such that the ribbon will at all times be raised into the path of the type on atypebar and will be dropped to a position where the writing is exposed as the type-bar returns to normal position.

In a machine using a narrow ribbon it may not be necessary to provide more than three or four series of projections 60 of different lengths or heights, and these sets or series may be variously disposed throughout the type-bar system. I have shown at Fig. 3 a set of three projections arranged in step-like order; but the number in a set may be less or greater than three so long as the projections vary and are able to cause the ribbon to move widthwise different degrees.

The inking-ribbon is moved longitudinally or from one spool to the other after the typebar has moved the ribbon transversely and made its impression upon the paper upon the platen by means of the gearing between the spring-drum and the ribbon-spool shaft, as shown and as is common in prior machinesthat is to say, after the type-impression and when the carriage moves one letter-space to the left the spring-drum turns the shaft 35 and the counter-shaft 38 and its associated ribbon-spool 4l, which for the time being are connected with said shaft 35, and the ribbon is thus wound one step or fora small portion upon said spool. When this spool has been filled, the ribbon-Winding may be reversed by shifting the shaft 35 endwise and causing it to be connected with the opposite countershaft 38 and its associated spool.

I have illustrated my invention in its application to a front-strike type-writing machine, and while the invention considered from certain aspects is particularly adapted for so-called visible-writing machines, of which the front-strike machine is one variety, the invention may be employedin other types of machines and various changes may be made in the construction to adapt the invention to such other machines.

Instead of providing projections 60 of different lengths upon the type carriers the plate 54 may be provided with variously-projecting contact-surfaces 60, which coperate with the type-bars at different periods of their movements to the printing-point, as indicated at Fig. 7.

I prefer to provide the plate 54 with a cushion or facing 54a of leather, rubber, or the like to prevent undue noise when the typebars strike and operate the plate 54.

In some cases the projections 60 may be omitted and the remainder of the mechanism be used simply for moving the inking-ribbon from the normal position, which exposes the last letter printed, to a position where it will be interposed between the type and the paper just before the type reaches printing position.
