To tzz whom it may conccm:

Be it known that I, HABBY SMITH, a .citi

zen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Linotype-lnstructlon Devices, of which the following is a specification, reference being had to the accompanyin drawings. a

My invention relates to devices having character key-boards asv a class. 7

The object of my invention is to provide a linotype keyboard in relation with a typewriter' machine of common type, ina mannerwhereby the mechanism of the typewriter-1 may be operated automatlcally by the linotype key-board mechanism, to produce prints of visible characters corresponding to those required by the linotype. This object, as 'wellfas other advantages, I attain by the construction, comblnation and arrangement of parts shown in the accompanying drawings which form a parthereof. Figure lvis a side elevation of linotype key mechanism and typewr ter mechanism above it, parts being in sect1on,-and partly onthefline I J in Fig. 2. r p

Fig. 2 isa front elevation of the upper part of the linotype key mechanism and typewriter mechanism above, and showing intermediate mechanism.

Fig. 3 is a plan view of intermedlate levers from the linotype striking pins to the drawing rods-showing change 1n courses. Like characters refer to'llkeparts 1n the views.

, A linotype key mechanism case 4 is illustrated. It has therein keys'5, key levers 6 and striking pins 7, with intervenin mechanism 8, between the levers 6 and pins 7 all of which is of the common type usually found in linotype or type casting machines. The intervening mechanism outlined in Fig. 1 as a part of the linotype machine shows; the usual continuously rotating power shaft 8, a horizontal bar 8 pivoted at one end in the case above the shaft, the vertical pin 7 rigidly secured at its lower end upon the opposing end of the said bar, a cam member 8 pivoted in the central part of the horizontal bar above the shaft in position to be dropped into engagement therewith, a vertiealarm 8 engaging at its lower end the inner end of the key lever 6, a cam lever 8 pivoted near the upper end of the vertical arm, one end of the lever engaging this arm nearlits upper end, the opposing end of the e ent-ea sent. 1 921 lever positioned ,tO- raise'the horizontal arm and thereby lift its earn. member, but ofengagementfwith;the'shaft era-116w ittodrop to engagement, therewithf LA typewriter case'9,in part, is also shown It has. therein typewrlter' 'key"s ';'10,"key levers 11, type bars 12, means 13 to connect thelevers .11 and bars 12. It also hasa j platen 14,:adapted to engage and rotate paper in a position to receive imprints 'thereon'from the type .15

on the bars 12." On the. upper part of the case 41 a transverse shaft 16 is rigidly mounted. Along this shaft a'series of levers 17 are pivoted thereon with spacingcollars 18 between them. 7 One free end of each of these f levers is arranged above a desired'striking pin 7 of the linotype mechanism, thelever is angled on the opposing side of the pivot shaft n'a desired'direction to'bring theoP- posing end of the, lever below the outer end of'a corresponding typewriter key lever 11;

A rod 19 is pivoted at its lower end in this opposlng end of the'lever 17 and extends upwardly to a pivoted'connection with the corresponding typewriter lever 11 near its keylO.

It willnowbe seen thatiwhen ailinotype key is struck by theoperator, for rexample the key bearing the character A, the cam' lever is caused to move sufficiently to iallow the horizontal'barto :drop', its cam member into engagement with p the power shaft,

which automatically causes the member to make a revolution and the pin 7 to. rise.- Thereupon the pin 7 engagesthe lever 17, which in turn automatically draws the rod 19 downwardly and the rod depresses thecorresponding typewriter key lever 11, and thereupon the .type bar 12, bearing the character A, is actuated. This causes the type to strike the paper in the usual manner of typewriters, and makes its imprint of the character Ann papervheld for the reception thereof on the platen 1 1. It is well known that the linotype keyboard is longer than the key frame of the typewriter, hence it is necessary to arrange the levers 17 at suitable angles between the linotype striking pins and the positions of the typewriter key levers above. It is intended that the typewriter shall be secured in any suitable manner above the linotype key case to retain both rigidly in relation to each other. The principle of my invention lies in the connect ing of the linotype key mechanism with the typing mechanism of the typewriter, without material change of parts in either. It is well known that those desiring to learn the operation of a linotype key board cannot do so on a complete linotype, without either using the entire mechanism to form finished cast type, or they must strike the keys with the casting mechanismcut off. In the latter case there isno means provided whereby the practising operator may know whether or not he is striking the keys correctly to make type corresponding to the copy before him. This is overcome by arranging the typewriter with the linotype keyboard, and the actual. imprint result of each linotype key struck, is at once registered and made visible by the imprint of the typewriter type.

I While I have shown a practical and operative; mechanism between that of the linotype and the typewriter, I do not limit myself't'o the'precise form thereof, but contend that the principle involved embraces any suitable and desirable, intermediate mechanism oflike character, intended to produce thesame result described. Therefore, in the construction of my device, I assemble the linotype key mechanism apart from the remainder of the linotype, a typewriter arranged .in a suitableposition with relation to the said'linotype mechanism, and then I present'device very economical and is new connect the first and second mechanisms withadesired intermediate means, whereby the second may be operated automatically by the operation of the first mechanism only. It is also intended that the intermediate means shall be adapted to any common character arrangements of both linotype and typewriter mechanisms. In this way the use or necessity for-any special form or arrangement of either is obviated. This makes the and "useful' 'Atpres'ent those desiring to :learn the operation of a linotype are unable with'a rigid vertical pin on its opposite free end, a cam'member pivoted in the bar above the shaft,a slidable vertical arm engaging at its lower end an opposing linotype key-bar, a cam lever pivoted near the upper end ofthe arm in position where one part of the lever engages the upper part of the arm and the opposing lever part supports the bar in sliding engagement therewith, a typewriter mechanism of common type, and a lever pivoted at its center on the linotype case, its free end extending over the free end of the aforesaid pin, and having a rod extending from its opposing end toa desired typewriter. key-bar, the whole being arranged to allow the cam lever to be manually moved to permit the bar to drop sufii ciently so that its cam member may engage the shaft, and the shaft automatically to cause said member to raise the free end of the bar and the end of its pin to deliver an impact stroke to the intervening mechanism and it in turn to actuate a desired type keybar to an impression.
