SPECIFICATION formingpart of Letters Patent No. 719,346, dated January 27, 1903.

Application led August 6, 1902.

T0 @ZZ whom, it nto/y concern:

Be it known that I, GEORGE H. LILLIE, a citizen of the United States, and a resident of Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Improvement in Type-Writers, of which the following is a specification.

My invention relates to an improvement in typewriters, and has to do more particularly with improved mechanism for carrying a plurality of ribbons side by side and means for shifting from one to the other, a primary object being to permit the use of ribbons of different colors or both record and copying rib bons at the same time, the advantages of such an arrangement being perfectly obvious, as the two ribbons occupy no more space than an ordinary broad ribbon, with the possibility of variation in the color of the print for emphasis or other purposes, with practically no loss of time in making the changes from one ribbon to the other or from one color to the other where different colors of ribbons are used. In addition to the advantages mentioned may be mentioned the fact that for the same length of ribbon less material is necessary, as the width of each ribbon is about half that of the ordinary ribbon, and they may be half as long again.

With the foregoing objects and advantages in view my invention consists in a ribbonplate such as is ordinarily used on the Remington and all of that class of machines, in connection with means carried thereby for keeping the ribbons apart and preventing their twisting and means for quickly shifting and locking the ribbon-plate to and in either of its extreme positions.

My invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view from the left-hand end of a type-writer, showing portions of the framework and my improvements attached thereto. Fig. 2 is a plan View of the ribbon-plate, showing the two ribbons carried thereby side by side, the dividers interposed between the ribbons, and

and locking the ribbon-plate. Fig. 3 is a vertical sectional view on the line y {1/ of Fig. 2.

serial No. 118,676. (No maar Fig. 4 is a detached view of-one of the dividers. Fig. 5 is a sectional View through one of the ribbon-spools, showing a clip for fastening the ribbon thereto; and Fig. 6 is a perspective view of my complete device detached from a type-writing machine.

R represents a ribbon-plate such as is generally used on the Remington and similar makes of type-writers. The plate shown has the usual open center, as shown at R, and is provided with transverse slots R2 at or near its opposite ends.

S and l indicate two ribbons which travel beneath the plate side by side, they being carried over spools U U, mounted in the usual or any approved manner on shafts t t at opposite ends of the machine and upon which the spools are capable of sliding, as indicated in dotted lines in Fig. l, when the ribbonplate is shifted to bring the desired ribbon into place.

The ribbon-plate is generally hinged to a frame V. This frame V is supported in position over the type-bed by means 0f a pair of swing-arms l l, pivotally secured thereto and to the frame of the type-Writing machine at any suitable point. One of these swingarms is provided with a spring s, mounted thereon and adapted to normally retain the ribbon-plate and its frame at one extreme limit of movement, thus operating to normally throw the spools and plate' rearward, which action would bring the outer ribbon T normally into position for printing.

A shift key or lever A of bell-crank form preferably, the angle of its parts being acute, is preferably pivoted, by means of a stud d, to a bracket A', which latter is iitted Aand detachably secured by a bolt, screw, or equivalent means a" to the frame F of the machine. A connecting rod or link B is pivotally connected at its outer end, as at b, to the shorter arm of the shift key or lever A and preferably on the outer side of the latter, the arm being bent or offset, as shown in Fig. 2, so that the connecting-rod will clear the stud a. This connecting-rod, as illustrated, is bent, as shown in Fig. 2, first inwardly around the frame or leg of the machine, then rearwardly alongside the depending arm G, in which one of the shafts t is journaled at its forward end. Then the rod is bent inwardly again ICQ around the rear of said depending arm, after which it extends rearward for a third time and terminates in ahook h, which enters the slot v in the D-shaped frame V, to which the ribbon plate is hinged. The construction described is merely an approved form of connecting-rod to cause it to occupy the least possible space, and it is obvious that its exact shape might be varied indefinitely according to the place it is to occupy or the machine to which it is to be attached and that it might be differently attached, if desired. It will be noticed that the shift key or lever and spring s always operate in opposition to each other--that is to say, the spring always tends to throwl the frame-plate and spools backward toward the rear of the machine, as previously stated, and my improved shift key or lever is devised to positively shift the ribbon plate and spools forward against the action of the spring when the other ribbon is to be used and to lock them in that position,

, and this is accomplished by the peculiar form of shift key or lever, which when thrown downwardly against a stop w vlocks the ribbon plate and spools forward as a result of the forward end of the connecting-rod passing the dead-center or pivotal point of the lever. The release is effected by raising the shift key or lever until the rod repasses the dead-center, when the spring s is free to act in its accustomed manner to slide the ribbon plate and spools back to their normal position.

Where ribbon-shifting mechanism is used, as is common with the most approved machines for automatically shifting a single ribbon, this mechanism is disconnected when the two ribbons are used, and the mechanism for shifting them just described is used instead for controlling the position of the ribbon-plate.

As a means for keeping the ribbons apart and preventing their crossing or twisting spring-dividers C C are employed. These are made of spring metal, the upper end being in the form of a head having a groove c in one side and a depending V-shaped spring d, .which serves a double function, one being to hold the divider in position by virtue of its spring action and the other to depend between the ribbons lo keep them apart. These dividers are usually inserted in the innermost slot R2 at each side of the opening R in the ribbon-plate. When in place, the groove in the head receives an edge of the slot, and the free end of the V-shaped spring CZ engages the opposite edge of the slot, thus holding the divider securely in place. After being thus placed if not precisely in the center it is possible to slide the divider without removing it to get it into the exact position required. As mentioned, the purpose of these dividers is to retain the two ribbons in their prescribed paths and to prevent their crossing and twisting and to keep the ribbons apart when reeling. As a simple means for attaching these ribbons or, in fact, any ribbon or ribbons to their spools and to avoid pinning, as heretofore, a groove u is formed in the ribbon spool or bobbin and the spring clip or clips W are sprung into place, after first inserting the end of the ribbon or ribbons in the groove to clamp the latter in place. To remove the ribbon from the spools, these clips may be sprung out of place with equal facility.

By the use of myinvention, as hitherto mentioned, different colors of ribbons may be carried at the same time or a record and copying ribbon may be used side by side. It is likewise evident that two ribbons of the same kind might be carried at the same time.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*
