OMAR MILLARD HIGHLEY, F CONVERSE, INDIANA.

TYPE-WRITER.

To all eohom it may concern .Be it known that I, OMAR MILLARD HIGH-- State of Indiana, have invented certain new and useful Improvements in Type-Writers,

of which the following is a specification.

This invention relates to. a typewriter of that class more particularlycharacterized by the fact that ri'bbon inking means for the type characters is completely eliminated.

One object of the present invention resides in providing a typewriter wherein the type members move relative to the platen and to the surface to be printed on, so as to produce line writing in this manner, instead of moving the platen and its supporting carriage as is the case in that class of typewriting machines employing a bank 0 type members.

Another object resides in the construction wherein a rotatable type member carrying a plurality of .type characters arranged in one or more concentric rows is provided, and also in arranging means to select, advance and impress any desired type member.

A further object consists in the particular means for moving the platen relative to the type .member.

Other objects of this invention will appear in the following description, which is to be considered in connection with accompanying drawings, wherein I have-illustrated aspecific embodiment of the invention, said embodiment being illustrated merely for the purpose of explaining the principles of this invention, and not imparting a limitation thereto.

In the drawings: Figure -1 is a top plan view of a typewriter constructed according to the principles of my invention. Fig. 2 is a front elevation of the typewriter shown in Fig. 1. Fig: 3 is a side elevation of the typewriter shown in Figs. 1 and 2, and-with one side ofthe frame thereof removed so as to'display the details of the mechanism. F igml is a top plan view of the movable type member. Fig. 5-is an elevation of the face: of the rotatable type member ordisk. Fig. 6 is a view, in perspective, of themeciprocating shoe for moving the type member. Fig. 7 is a detail view, in perspective,

. of a type character and, strictly speaking shown, comprises the frame 1, having pivotally mountedthereon at 1 the arms 2 Specification of Letters Patent.

carrying the rotatable platen 2, saidarms Patented July 4.51916. Application filed December 31, 1915. Serial N 0. 69,685. r

being normally supported by engagement with stops 2, said stops limiting the down: ward movement but not restricting upward movement. At the back of the platen 2 are provided rollers 3 for engagement with the paper to be held by the platen. Smaller rollers at are provided on the front part of the platen to hold the paper in position,

while underneath the platen 2 is a curved v guard 5 serving to protect the platen and paper. One end of the platen 2 carries a ratchet wheel 6 for engagement by a pawl .7; and a knob 8 is provided which may be used to rotate the platen to advance the paper carried thereby for successive line printing. The pawl 7, by dropping in the various notches of the wheel 6 serves to indicate the proper setting of the platen for different lines of printing.

Beneath the platen 2 and extending transversely of the framel are the two parallel guide bars 9. These bars support a carriage 10 sli dab-le therealong and which is connected with one end of a tension strap .11, the other end of which is connected with a tension spring housed within the casing 12 carried by the frame 1.

The carriage 10 is provided with the front and rear uprights 13 and 14 respectively, in

which is journaledthe horizontally extending shaft 15 spirally splined as shown at 16 and provlded with the reduced rear end portion 17,. pointed at its extremity, and

bearing on the free end of a U-shaped spring 18, the latter being fastened to'the said carriage-lQ. The forward end of said shaft 15 carries a type member 19 which is fixed thereto so as to be rotatable with the shaft, said type members being preferably in the form of a disk having the'individual arms 20 carrying the concentric rows of type and so spaced apart as to-render the writing produced visible. The shaft 15 is confined between the uprights 13 and 14 in such a manner that its movement. is limited to the length of the extension 17, the forward end of the shaft being extendedthrough said type disk and bearing against a spring .30

' carried by the impression lever 30. However, such movement of theshaft is merely to compensate for the impression on the platen the greatest movement that the shaft 15 is capable-of is merely to compensate for a blow on the rotatable type member which blow is absorbed by the spring 18. The type lmember-l9 is provided with a plurality of resilient type arms 20, each of which as hereinbefore stated, carries two type mem- A bers, the said type members or characters being arranged in concentric rows. Beneath the shaft 15, and 'slidable along longitudinally of the carriage 10, is a block 21 which seats at 22 on said carriage 10 and the upper 10 face thereof is hollowed out as at 23 re- 15 'nally of the carriage 10, it imparts a rotative movement to the type member or disk 19 through the medium of the shaft 15. Confined between the block 21 and the upright 13 is a spiral spring 25 which acts to 20 always return. block 21 to a normal starting position thus after each movement of the type member 19, the same returns to its initial starting position. The type characters are suitably inked by means of an ink 25 supply roller 26 carried by pivot 27 located on the upright 13 of the carriage 10, and as the type disk 19 is rotated this roller 26 rolls successively into engagement with each type character. The carriage 10 carries a depending arm 28 having pivoted theretoat 29 a substantially vertical impression lever 30, the lower end ofwhich is curved around as shown at 31' and connects with a lever 32 which, in turn connects with a bell crank 33 85 carried by the upright 14 and one arm of Y which engages with the spring 18, the resiliency of which serves to return said impression lever 30 to its normal position after an impression has been effected. At its upper end the impression lever '30 is provided with a pad 31, for purposes to be hereinafter described. The guide bars 9, along which the carriage 10 moves, are carried by the frame members 1. Engaging with the impression lever and extending across the front of the machineis abar 36 which isconnected at each end with rods 37,

the other endsof which connect with the long arm of a bell crank lever 38, theshort arm of which is adapted to be engaged by the rear end of a type lever 39, said type.

- In order to provide for selecting any type character, a belhcrank lever 42 is arranged '65 at the rear of the typewriter and is adapted to have its short arm engaged by a lug 43 carried by the type lever, and the long arm of aid bell crank lever 42 is connected by means of rods 44- with a transversely extendin bar 45 which engages block 21, and upon epressing the key 41, the said block 21 is moved and which, by reason of the en gagement of the pin carried thereby with the spiral spline, rotates the type member J9. The proportionment of said lever hereinbefore described is so arranged that the proper arm 20 carrying the type character indicated on the key 41 will be advanced into printing position.

As before stated, the type member 19 carries a plurality of concentric rows of type characters and, in order to use either row, means for shifting the carriage vertically together with its platen 2 must be provided. Such means consists of the arms 45 which engage with the arms 2 and which, at their other ends are provided with shift keys 46 so marked. Thus as either shift key,,46 is depressedv the platen 2 will be elevated so that the outer row of type characters may be used for printing purposes,

is rocked the proper spacing will be effected.

I Of course, 'for advancing the type characters to be in After each impression it is necessary to In order tospace without printing the bar I 47 is supported ,on the ends of bell crank levers'51 pivoted at'52 to a shaft mounted the frame 1, and the other end of each bell crank lever carries the space bar 33, thus when the space bar 33 is moved the type member 19 willbespaced relative to the platen in a longitudinal direction, and by reason of the formation of the escapement, that is to say the spring 49, the type member may be moved back in the usual manner.

The operation of the typewriter is asfol lows When it is desired tov produce writing, the paper is rolled beneath the platen and extends upwardly as is the case in the usual typewriter, The carriage 10 is then adjusted'to the proper position to print a line, and the letters are depressed in succession in the usual manner, but instead of'the platen moving, as is the case in the usual typewriter, the type is moved along relative to the platen and thereby produces a line of writlng. After the type member has 'reached its limit of travel the same is returned to its normal writing position. The

machine is then ready to print another tinctly understood that modifications may be resorted to without departing from the spirit and scope of the invention as defined in the appended claims.
