JOSEPH DEIJA AR, OF NEIV YORK, N. Y., ASSIGNOR OF THREE-FOURTHS TO RICHARD V. INGERSOLL, OF SAME PLACE, AND ANDREVJ ANDERSON, JR, OF JERSEY CITY, NEV JERSEY.

TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 623,502, dated April 18, 1899.

Application filed July 18, 1898. Serial No. 686,263. (No model.)

To ctZZ whont it litany concern.-

Be it known that I, JOsEPH DELA MAR, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new i and useful Improvements in Type-\Vriters, of which the following is a specification.

My invention relates to an improvement in type-writers; and it consists in vertical hangers secured to each end of the type-writer frame and which are provided with horizontal slots, holders having studs which pass through the said slots and support the holders in position, combined with operating members for the spools, spools placed upon the members, connecting-rods for moving the holders laterally, an operatingdevcr to which one end of a connecting-rod is fastened, and means for locking the operating-lever in position, all of which will be more fully described hereinafter.

Other essential features will be pointed out in the claims and specification.

In the accompanying drawings, forming part of this specification, Figure 1 represents a vertical central sectional side elevation of the vital parts of a type-writing machine, showing my improvementin the ink-carrying band, the other parts of the machine irrelative to the invention being omitted. Fig. 2 represents a side view of the portion of the machine to which my ink-carrying-band-opcrating parts are attached. Fig. 3 is a detached vertical section of the lever mechanism for interchanging the ink-bands and their holders. Fig. 4 is a detached top view of my several ink-carrying bands and their holders and operating parts of the same shown on a reduced scale. Fig. 5 is a longitudinal vertical section of the same. Fig. 6 is a detached longitudinal vertical section of a pair of inkcarrying-band holders shown on a full-sized scale. Fig. 7 is avertical lateral section of the same.

The letter A of reference indicates the papercarrying roller of the type-writer and 13 its pressure and feed roller, and C the liftingframe carrying said rollers, pivoted to the frame D of the type-writer.

E E represent the usual type hammers or printers, and F is one of the key-levers which are connected by the rods G with the hammers E for operating the same.

II is the right-hand front leg of the typewriter.

I I represent each an ink or color carrying band, which is arranged to feed and pass longitudinally under the paper-roller A,while most of the type-hammers E are arranged lateral to said roller and press the type up against the band I and with it upon the paper being printed. Each end of the band I is wound upon a spool K, of which one spool for each band is employed under each longitudinal side of the frame D of the machine, as shown in Figs. 1, 3, 4, and 5. Now instead of one band I, I employ two or more, side by side, as shown in Figs. 1, 2, and 4, and for every additional band I also provide an additional spool, and each band I is wound with its ends upon its relative spool by the usual hand-arbor f and the engaged gear-wheels, as heretofore. For each band I, I employ aguidepassage J above each spool,passing above the frame D, to conduct the band in proper line from spool K over the frame and down through the frame upon the opposite winding-spool K.

All spools K at one end of the frame D have one common arbor 7c, and the guide-passages J have one common holder J, to which they are attached above the frame, and thisholder passes down through the frame over the outside of the spools and is attached to a vertical hanger M, which projects down from the bottom side of the frame. vertical portion L to join the hanger to which it is held and is guided to slide horizontally thereon, and said holder J has an opening J for each band to pass through into its top horizontal guide-passage J. Said guide-pas- 9o sage J has a solid bottom portion t over which the band passes and which protects the band from contact in sliding laterally over the typehammer fixtures and screws 2' on the top of the frame, and said passage is made with lips 95 e e to overlap each edge of the band to guide it properly undisturbed, as shown in Figs. 1,

2, 4, 5, 6, and 7.

The holder J has a The horizontal guide passage J of each guide extends only over that portion of the bands which is not engaged by the type-hammers. The spools have a flange between the bands to separate them. Each said vertical hanger M has a horizontal slot N, and the vertical portion L of the guide-holder J has two horizontal studs 72., with friction-rollers passing and fitted into said slot N and furnished ,with riveted washers over the outside of said slot, as shown, by means of which said guide-holder J is held to its hanger ill, but at the same time is free to slide along the hanger. A central horizontal stud .2 is provided on the holder J, passing also through said slot N, and upon its outer end are employed a link and a washer and screw-nut to hold the link upon the stud. Upon the outer edges of each vertical portion L are formed the vertical flanges m, which catch against opposite ends of the spools for the purpose of causing the spools to slide with the holders .I, and thus shift the ribbons; but the said arbor is fitted in the spool with a key in the pulley and a groovein the arbor to prevent the spool from turning loosely. By this means the spools are obliged to move longitudinally with the holders J. The arbors 7; are rotated whenever required by winding by the countershaft f, carrying the bevel-gear pinions, one of which may engage the bevel-gear upon the requisite winding-arbor 7c of the spool being wound. The links 0 of both guide-holders J are connected each with the loose end of a vertical lever P on each end of the frame, which levers are both attached on the outer ends of a common horizontal rock-shaft Q, passing through and guided in the front legs 11 of the machine, as shown in Figs. 2 and 3. The lever P at the right-hand leg II is furnished with a locking-arm R, carrying a locking-bolt-releasing handle S and a spring T to engage said bolt and handle. To said righthand leg II is attached back of the lever P a segment-plate V, which is made with suitable locking-holes It for stopping the lever P at the proper position desired or required for the ink-band selected to be used for printing.

It will be observed from the drawings that the ink-carrying band shown engaged by the type-hammers in all views is that which is shown in full black lines in Fig. 4, and the band not engaged is shown in dotted lines in the position shown in Fig. 4. The broken-oil; guide-passages J occupy the position which the band shown in full lines would take were the band in dotted, lines moved into the central position.

It will be observed that the guide-passages J, having the solid bottoms 15, pass over the screw-heads and projecting parts on the top of the type-writing-machine table, and there by carry the band I clear of any obstruction on the top of the table, which has heretofore been very objectionable.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a type-writer, vertical hangers sccnred to the frame of the machine, and provided with horizontal slots, holders provided with studs which pass through said slots and support the holders in position, each holder being provided with flanges for catching over the ends of the spool, combined with suitable operating-arbors for the spools, spools placed upon the arbors, connecting-rods for moving the holders laterally, and which are connected atone end to the holders, an operating-lever to which one end of the connecting-rod is fastened, and suitable means for locking the lever in position, substantially as described.

2. In a type writer, the holders J provided with openings J, through which the ribbons pass, and with horizontal guidingflanges upon its top central portion, studs 'which project from the outer ends of the holders, and flanges formed upon the sides of the holder, combined with the vertical hanger M provided with horizontal slots N through which the studs upon the holders project, a connecting-rod connected to each holder, an operating-lever to which each of the connecting-rods is attached, and means for locking the operating-lever in position, substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 15th day of July, A. D. 1898.
