Specification of Letters Patent.

RIBBON GUIDE AND POINTER.

Patented Dec. 12, 1911'.

Application filed February 19, 1910. Serial No. 544,953.

To all whom it may concern: 7

Be it known that we, HALBERT E. PAYNE, a citizen of the United States, and a resident of New York city, New York county,

- State of New York, and SILAS G. WRAY, a

citizen of the United States, and a resident of Grand Junction, Colorado, have invented certain new and useful Improvements in Ribbon Guides and Pointers, of which the following is a specification.

Our invention relates to typewriting machines, and particularly to a cheap and simple form of ribbon shift and pointer for such machines. p

One of the objects of our invention is to provide a ribbon shift, that is simple and inexpensive to construct, and that can be readily attached to a typewriter without altering or reconstructing the machine and that will enable the type to strike all parts of a single or multi-color ribbon. 1

Another object of the invention is to provide a ribbon shift mechanism with a pointer so arranged that it will prevent the beginning and tail end of a sheet of aper from coming into contact with the ribbon, at the same. time indicating the position of the next letter to be printed when the platen is thrown up to show the writing.

WVith the above and other objects in view, our invention consists in the parts, improvements and combinations, more particularly pointed out in the claims.

Referring now to the drawings which are attached to this specification and form a part thereof: Figure 1 is a view of, a typewriter carriage with the platen thrown up to inspect the writing, to which the improvement has been added. Fig. 2 is a front elevation showing the operation of one of the pointers secured to the framecarrying the ribbon shift. Fig. 3 is a side elevation with parts broken away showing the ribbon shift and pointer, when the paper is in the machine and the platen has been lowered ready for writing. Figs. A, 5 and 6 are details of the ribbon shift and pointer.

As illustrated in Fig. 1, the platen 1, is rotatably mounted in the pivoted platen carrier 2, pivoted at 3 in the reciprocating carriage 4 of the typewriter. The arms 5 of the platen carrier carry a scale 6 at one end. The paper 7 is fed into the machine in the suitable means for feeding the ink ribbon,

such as the gear 16 connected to a spool,

and operated from the universal bar of the machine or in any desired manner, may be used. y In accordance with the invention, we providea ribbon guide and pointer, together with means for shifting the ribbon guide, so as to print either black or red at will, and so as to use all parts of either the black or red ribbon or of a single color ribbon, if the latter is utilized. We make use of a frame 17 having sides 18,.the sides being united at one end to form a pointer 19. This pointer coiiperates with-the'scale 6, to indicate the position of the carriage when writing. A pair of arms 20, suitably spaced from the sides 18, so as'to leave openings 21, are provided. The arms 20 are also separatedfrom each other, so as to leave the opening 22 be tween them, the ribbon passing across said opening, and the type bars making their im pression by pressing against the ribbon when stretched over said opening. The type bars pass through an aliner or guide 23, the ribbon being stretched over the mouth of the aliner by the action of the ribbon-guiding mechanism. A sliding ribbon guide for shifting the ribbon transversely to bring either color under the printing point and to adjust the ribbon so as to use all parts of it is supported and guided on the arms 20. The sliding guide consists of a frame 25, provided with a handle 26 secured and pref; erably integral with saidframe, the frame being provided with bent projections 27, that embrace the edges of the arms 20, so as to guide the ribbon guide 25'to and fro. Lugs 28 connected to the frame 25 are also provided, the lugs sliding in the notches 29 on arms 20. These lugs determine the innermost and outermost position of the frame 25 by striking

shoulders

30 and 31 at the ends of the notches 29. Ribbon guides are formed on the frame 25 and are preferably integral therewith. They consist of the

lips

32, 33, 34 and 35, whichprovide openings 36 and 37 to admit the ribbon. The lips preferably do'not meet, but leave an open space 38 between them to permit the ready insertion of the ribbon edgewise through the openings into the spaces 36 and 87. A pointer 40 carried by arms 41 is pivotally secured to a rod 42, carried by the frame 17. A coil-spring 43 with an arm 44 surrounds the rod 42, and presses the pointer 40 upwardly toward the platen, so that it follows the platen when the latter is swung upwardly to inspect the writing, and points at the next letter to be printed, as clearly indicated in Fig. 1.

The pointer frame 17 and sliding ribbon guide 25 are preferably each made of sheet metal, so that they may be quickly and cheaply stamped out. Means are provided for removably securing the combined ribbon guide and pointer to a frame which shifts in order to shift the platen frame to print upper case and figures. For this purpose, brackets 45 integral with the frame 17 are preferably provided, the brackets being secured to the carriage frame by screws 46. In the embodiment of the invention illustrated the brackets 45 are secured to a frame 47 which carries the rails 48 so that the ribbon guide is secured to the means for shifting the carriage which in turn shifts the platen. Other means for shifting the platen may be used.

In the form shown in the drawings the frame 47 is pivoted at 49 to a pair of arms 50, one on each side of the frame. The arms 50 are pivoted at 61 in the fixed frame of the typewriter. An arm 51 extends from one arm 50 and is connected to a shift key 52 which is pivoted at 53 and carries a stud 54 that engages a slot 55 in a projection 56 that is attached to the arm 51. By depressing either one of the keys 52 the platen is shifted in the desired direction. The entire ribbon guide and pointer mechanism may thus be easily put in place and removed from the machine at will and shifts with the platen so as to be in proper position at all times.

The operation of our invention will be evident from the foregoing description.

By catching hold of the handle 26 which is in plain view and near the operator, the ribbon guide may be shifted to change the color of ribbon used. When the platen 1 is raised, the pointer 40 follows the platen, and shows the position of the next letter to be printed. The pointer 19 indicates the position of the carriage. The pointer 41 located and arranged as described, also serves to prevent smudging the beginning and tail end of a sheet of paper, or the closing flap of an envelop, which has a tendency to leave the platen roll and strike the ribbon when it is fed by the platen through the machine.

It will be understood that our invention is not confined to the particular form of ribbon shift and pointer illustrated, as modifications may be made therein, without departing from the principle of the invention.

Having thus described our invention, what we claim and desire to secure by Letters Patcut, is

1.
