Referring to the drawing which is merely illustrative of my invention a base board or key board is designated i0 being inclined when applied upon the key-board of a slug-casting typesetting maohine. One of the supports I I for this 19 key-board is shown in Figure 3, and the angular lug I3 thereof is secured by rivets I2 to the base board It by reason of which the vertically disposed support II holds the base board in inclined position, the lower right angular portion M of this support resting on a part of the slugcasting typesetting machine.

Two vertically disposed props I 6 are attached to the other end of the baseboard ID at each side thereof. The lower ends of these props are re-- 3U spectively formed with the recesses IT to engage the assembling elevator lift rod I5 of the slugcasting typesetting machine, so that this rod serves to support the lower front part of the baseboard IO.

In this manner the frame or baseboard I0 is caused to be supported in superimposed position directly over the keyboard of the slug-casting typesetting machine, the keys of the latter being designated 34. With the baseboard I0 disposed and mounted in this manner it will be seen that same can be removed at any time. It may be understood that slug-casting typesetting machines will be built so as to eliminate the former keyboards found on them in favor of the improved key-board forming the subject-matter of this invention.

A plurality of keys I8 are provided for depressible action upon the key board or base board I0, and these keys follow the exact order and disposition of the usual keys of the standard types of typewriters so that typists accustomed to handling and operating typewriters or the like can operate slug-casting typesetting machines by depressing the keys IB according to the same touch method as is used in the operation of the usual typewriter keys, the concordance between the slug-casting typesetting and standard typewriters being brought about by my invention. The keys I8 are securely mounted upon the extreme outer ends of leaf spring arms I9 which are secured at their inner ends by fasteners 22 to the blocks 23 which are or may be insulator blocks. The shape and arrangement of the spring arms I9 is such that they normally support the keys in a horizontal plane.

Besides the keys IB devoted to the usual letters and numbers and punctuation marks shown in Figure 1 there is the usual typewriter shift key lever having the key 20 and the latching key 2| therefor. A series of electromagnets 25 is provided of which one magnet is related to each key of the series of keys on the machine keyboard. Each magnet is supported on the underside of the board ID by a fastener 24 secured into this board. Each fastener also secures the right angular portion 25 of a hanger 21 to the underside of the keyboard so that each hanger is rigidly supported in parallel relation to the principal axis of its associated electromagnet. The lower portion 28 of each hanger serves as a ful-- crum bearing for a key pusher or a depressor 2s, pivotally mounted thereon intermediate of its ends, which depressor consists of the armature 3i normally positioned in operative relation to its individual magnet 25 and the downwardly curved metal finger 32 terminating in a curved key engaging toe 33. The toe 33 of each depressor 29 may if desired, rest upon the adjacent key 34 of the slug-casting typesetting machine which it is designed to operate. The magnets are thus secured insulatedly to hang from the base board to so that when the baseboard is removed the magnets and other parts of my invention are removed as one unit.

The shift key arrangement is described as follows. The shift key 20 is secured upon the vertically disposed arm 52 of a bell crank lever which is pivotally supported at 5| on an extension of the frame. The other arm 41 of this lever is designed to swing into electrical engagement with any one of a number of contacts, for example, one of the three contacts 49, 49a and 49b. These contacts are mounted upon the arcuate shaped piece of insulation 48 which is secured upon the underside of the board I0. There is pivoted at 43 on the arm 41 of the bell crank lever, a push rod or bar 33 carrying the latching key 2|. This bar 33 is provided at one side with a hook 40 to engage the slot 4| in the baseboard H! and is also provided at its other side with a hook 54 to engage the edge of slot 42 in this board so that the arm 41 can be latched respectively in engagement with the contacts 49a or 49b. A suitable tension spring 45 connects the bar 48 and the arm 41 so that the hooks 4!) and 54 can latch the shift key mechanism in the positions to which it has been adjusted.

The spacer depressible key is designated 54, and alongside the same is the em spacer 55, and alongside the latter is the en spacer key 56. These three keys are all in alinement and determine the operation of the proper em or en spaces or of the space band of the slugcasting typesetting machine. At each end of each of these spacer members is a screw pin 51 tapped into this member and also secured in the lower base board; alongside of this screw pin is another pin screwed into the member 54 as at 59, while a contact pin in alinement therewith is secured into the base board I0. As spring 58 is coiled around pin 51 which holds the spacer member spaced from the base board requiring depression of this spacer member before the spring is tensioned, which spring of course restores the spacer member to normal position when pressure is removed from the spacer memher.

The electrical circuit includes a magnet for each key in the series of slug-casting typesetting ma chine keys; a switch for closing the circuit to the magnet, and a pusher or equivalent device for releasing the matrices. Referring to Fig. 9, it will be seen that a battery or other source of electric current 62 is employed and from one side of this source there extends a wire 64 from which wires 65 included in branch circuits, lead to the respective keys I8 and when one of the keys i8 is depressed, a branch circuit is completed through its related contact 36, conductor 61, winding of magnet 25, conductors 55, E8 or 59, switch arm 41 to the other side of the current source. It will be understood that each of these branch circuits is normally opened at its key l8 and its contact 35, but by selectively depressing these keys, either alone or in combination with the shift key and locking key mechanism 29 and 2 I, branch circuits are selectively completed for operating the control magnets 25 and in turn the key pushers or other matrix releasing parts of the slug-casting typesetting machine. Each spacer key 54, 55 or 56 likewise completes a circuit for its related magnet 25, each circuit including the current source 62 and conductors 64 and 15. Only a few of the necessary magnets have been illustrated and this fact is indicated by the breaks occurring in the conductors 64, 69 and 1D.

In operation the operator familiar with the use and operation of any standard typewriter, depresses the keys l8 for the lower case, or shift keys 2|, 2D and keys H! for the large caps, or for the small caps and in this manner will cause the matrices of the slug-casting typesetting machine to be operated selectively and interchangeably as called for by the characters of the text. pressing any particular key Hi this key flexes the spring arm l9 sufiiciently to make the key IB and its individual contact 36 interengage; so that the circuit is closed from the current source 52 to the particular magnet associated with this key..

Thereupon this magnet becomes energized and draws to itself the armature end 3| of the particular pusher 29, and in drawing this end of the lever inward, the curved toe 33 is depressed, thereby depressing the appropriate slug-casting typesetting key 34 and operating the proper matrix to cast the proper character printed on the key depressed in the first place. In this connection it will be noted that the magnet may control the operation of any device designed to operate the proper matrices whether keys 34 be used or not. When the spacer members 54, 55 and 56 are operated, the particular size of space required is provided for in the line cast on the slug. Likewise when shift key 20 is depressed, it moves the lever 52 downward against the tension of spring 55 which is secured to board It! at one end and to lever 52 at the other end. This lever in turn tends to draw the latching bar 38 downward so that its hook 40 can under the tension of the spring 45 engage the slot 41 in the board It, or hook 54 can engage the edge of slot 42 thereby locking the lever 52 in adjusted position until lever 35 is disengaged again by key 2| to release the shift key 20.

I do not limit myself to the exact details oi construction disclosed herein but claim all variations falling within the purview of the claims in a slug casting machine.

are 90 keys on a Linotype or Intertype machine and their arrangement is cumbersome and intricate. Many of the keys bear characters which are repeated on other keys as occasion may warrant, as where the text calls for a character say A" small caps, large caps or lower case, as the case may be. These frequent repetitions In demake the slug-casting typesetting machine keyboard unwieldy, unduly large for quick action performed on the keys, and slacken the speed of the operator. Such a keyboard calls into requisition the left side of the machine more than the right.

The present invention contemplates the use of fewer than 90 keys, as each key bears a different character, whereas in the slug-casting typesetting the various characters are repeated three times. However each of certain keys 18 of the keyboard of this invention controls three magnets 25, for large cap, small cap, and lower case type requirements. Hence there will be as many magnets as there are separate slug-casting typesetting machine keys. Each magnet of the sets of magnets controlled by each particular key I8 is designed to be cut in and out of the electrical circuit by the operation of the shift key and lock Z0, 2!. Thus normally the arm 41 rests with its contact point 49 on the arcuate piece 48. One set of magnets 25 are now in circuit with the current source, the wire from each of these magnets running to one side of the current source by way of arm 41. These magnets operate the matrices for lower case. For large caps the key 20 is depressed, to shift arm 41 with its contact point into engagement with the contact 49a on the arcuate piece 48 as shown in Figure 9. The first set of magnets have now been cut out of the circuit and a new set of magnets cut into the circuit, wires from those magnets returning to one side of the current source by way of arm 41. For small caps, key 20 is again depressed to place arm 41 in engagement with contact 4% on arcuate piece 48 so that now the second set of magnets has been cut out and a third set of magnets cut into the circuit also having return electrical connections by way of arm 47 to one side of the current source. The arm 41 will always close the circuit to one magnet of any set of magnets when the proper key it! is depressed. In this way the entire range of 90 keys of the slug composing machine may be operated by means of fewer keys.

In this application and disclosure, it should be borne in mind that in any Linotype machine, Intertype or Linograph in use today the keys thereon are multiplied at great length and bear no relationship in order and arrangement to the keys of the standard typewriter. In any such slugcasting typesetting machine many years of practice are required before a slug-casting typesetting operator attains a proficient rate of speed, whereas typists on standard typewriters attain very great speeds at the expenditure of a fraction of the time and nervous energy consumed by the slug-casting typesetting operator. My invention brings about great simplification and facilitation in the setting of small capitals on the typesetting machine by providing a shift key to permit the operation of small capitals from the same keyboard as the one used for lower case and capital letters. This works an innovation in the operation of slug-casting typesetting machines. Thus any typist accustomed to speedily operating the standard typewriter may operate the slugcasting typesetting machine without previous study or practice and with very little diminution of speed. It is intended to construct the novel key board in a slug casting machine to replace the key-board now found on such machines and this may be done even by dispensing with keys at all so long as it is possible to selectively and manually control the operation and intervals of activity of the particular matrices which will form the characters desired on the slugs cast. Instead of having to reach far out as on present makes of typesetting machines to depress desired keys the novel keyboard becomes the real key-board of an existing typesetting machine and reduces to small compass the size of the keyboard.
