ANDREW GOOD, or LOS PATENT OFFICE ANGELEB, CALIFORNIA SLUG-CAS'IING TYPESETTING-MAGHINE OPERATION Application file d July 14,

This invention relates to improvements in linotype machines and more particularly to means for operating the keys thereof and has for its object to provide a simple, eflicient and inexpensive device ofthis character.

Another object of this inventionis to provide improved mechanism in a linotype machine for replacing the conventional linotype key-board by means of a standard typewriter keyboard.

' Another object of this invention is to provide means in a linotype machine for adapting the present linotype keys to a standard typewriter arrangement of keys.

' A further object of this invention is to provide a keyboard as an auxiliary or supplementary attachment to the present style of linotype key-board for the purpose of dispensing with special skill in the operation of the linotype machine.

A further object of this invention is to provide means for removably mounting the auxiliary key-board upon the key-board of a conventional linotype machine.

A still-further object of this invention is to provide mechanism magnetically controlled for manually operating the keys of a standard linoty e machine thru the medium of auxiliary keys.

Another object of this invention is to provide shift keys on. the auxiliary key-board with an arrangement for translating the action of the shift keys into operation of the proper keys on the linotype machine.

Another object of this invention is to provide mechanical key pushers for operating the keys of the linotype machine, said key pushers being magnetically and electrically controlled.

With the above and otherobjects in view my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specifications, and then moreparticularly pointed out in theappended claims.

Referring to the drawings which are merely illustratlve of my invention a base board or key board is designated 10 having an inclination when applied upon the keyboard of a linotype machine. One of the hangers '11 for this key-board is shown in Figure 3, being designated 11' and the angular In 13 thereof is secured by rivets 12 to the ase board 10-by reason of which the vertically disposed hanger 11 holds the baseboard in inclined position, the lower rightangular por- -tion 14 of this ban er being operatively secured to part of the inotype frame.

,A prop 16, is attached in operative manner to the other end of the base board 10 and is vertically disposed; two such props may be employed on either-side of the baseboard, the lower ends of which are respectively formed with'the recesses 17 in which is disposed the assembling elevator lift rod 01' the linotype machine so that this rod 15 serves to support the lower front part of the baseboard 10.

In this manner the frame or baseboard 10 is caused to be supported in surmounted position directly over the key board of the linotype machine, the keys of the latter being desgra'mmatic View of the cirand mounted in this manner it willbe seen that same can be removed at any time. It will be understood that linotype machines will be built so as to eliminate the present keyboards found on them in favor of the improved key board forming the subject-matter of this invention. v A plurality of keys 18 are provided for deressible action upon the key board or base om'd 10, and these keys vfollow the exact .40 chine which 'it is designed to operate; The

order and disposition of the usual keys of the standard typesof typewriters so that; typists accustomed to handling and operating typewriters or the like may instinctively operj concordance between the linotype and Istandard typewriters being brought aboutby my invention. The'keys 18 are securely mounted upon the extreme outer ends of leaf spring rangement of thespring arms 19 is such that they normally support the keys in a horiz'on-' tal plane. a

Besides the keys 18 devotedt'o the-usual letters andnumbers and punctuation marks shown in Figure 1 there are the usualtype writershift key lever having the key 20 and the latching key 21 therefor. A series of electro-magnets'25 are provided, one for each particular key of the series of keys on thekeyboard; each magnet 25 isstrungsecurely upon theu'nder side of the board 10 by a fastener of suitable construction 24 secured into this board and serving to position securel the rightangular portion 26' of a hanger 2 made of strap iron or'th'e like whose lower portiorr28 serves as a fulcrum bearing for'a key-pusher or depressor 29. Each depressor consists'of the armature end 31 arranged normally in spaced but contiguous relation with respect to the magnet 25 and thedownwardly.

curved spring metal finger 32 terminating in the curved key-engaging toe 33. This depres sor 29 is lever shaped being pivoted centrally upon the hanger portion 28. The toe 33 of each depressor 39 may, if desired, rest upon the adjacent key 34 of the linotype mamagnets are thus secured insulatedlyso as t'o unit.

hang from the base board 10 so that whenthe baseboard is removed the magnets and other parts of my invention are removed as one The shift key arrangement described as f follows. The'shift-key 20 is secured upon a .bell crank lever whose vertically disposed bell-crank lever and shift key device is a push arm 52 carries the key'proper, and whose remaining arm 47 is designed to'make electrical contact in its arcua'te sweep with any of a number ofconta'c'ts, say the three contacts 49 mounted upon the arcuate shaped strap 48 operatively secured upon the under side of the board 10. Pivoted upon the arm .47 of the rod or bar 38 carrying the latching key 21,

l and formed intermediate its ends with an "integr al hook 40a, 43 designating the pivotal" point of attachment of push bar 38 upon the arm 47 of the bell crank lever. A spring 45 connects the rod or bar 38-and the arm 47. for

joint movement, a. p ivot 51, fulcruming the arm 47 upon afixed hanger 50' alsoisecu'red 33' is' depressed, thereby depressing the-apto the under side of the board 10. The base board 10 is formed with a'- slot 42 for the -push bar 38to move in another slot 53 being hook 40a of the bar 38.

The spacer depressible key designated- 54", and alongside the same is the em spacer,-

the'pr'oper em or en spaces or of the space band'of the linotype machine. At each end of each of these. spacer members is a screw pin 57 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 an alining pin 60 is secured into the base board 10. A spring These three keys determine the operation of 58 is-coiled. around pin .57 which holds the The-electrica1c1rcu1t includes a-magnet each'key in the series of keys; a switchfor v closing the circuit to the. magnet anda pusher or. equivalent device for releasing the matrices. Referring to Figure 9 it will beseen that a battery or source of electricity'62 is employed, and from one side of thisbattery runs a wire 64 from which connect wires 65, 67139 the contacts 36 of the key board frame 10, the circuit however being openbetween wires 65, 67 due to the, key 18. beingnormally spaced out of engagement with the fixed. contact 36. Wire 67 nunsto the magnet 25;

from whichruns the wire "66 to the wire 63 which runs back to the other side .of the battery. In the same way the shift keys control magnets which operate the key pushers or the matrix-operating selective parts of the linotype machine.

In operati the operator familiar with the use and operation of any standard t pewriterjdepresses the keys 18,- or shift eys 21,, 20v for the large caps or 20a, 21a for the small caps, andin this manner will cause the matrices of the linotype machine to be 'operated selectively and interchangeably as called for by the characters of the text. In

depressingany particular key 18 this key flexes the spring arm 19 sufliciently to make the key 18 and the particular contact for switch 18 interengage; thereupon the circuit .is closed thru the battery or generator 62 to the particular. magnet associated with this gized and draws to itself the armature end 31 ofthe particularpusher 29, and in drawing this end of'the lever in the curved toe key; thereupon this magnet 'becomes'enerpropriate linotype key 34 and operating the machine. I

- In this application, and disclosure it should,

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; and when operating the particular shift key say shiftkey 20, in depressing lever 52 against the tension of springllb secured to board 10 at one end and to lever 52 at the other end, this lever in turn draws downwardly the latching lever 38 so its hook 40a will snap automatically, against the tension of the spring 45, into slot 40 of the board 10. thereby locking the lever 52 in set position until lever 38 is depressed again to release shift key 20. Thus the caps, lower case or small caps are cast. I do not limit myself to theexact details of construction disclosed herein but claim all variations falling within the purview of the claims in a slug casting be borne in mind that in any linotype ma chine, intertype and 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 slug casting typesetting machine many years of practice are required before a linotype 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 occasioned by the linotype 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 linotype machines. Thus any typist accustomed to speedily operating the standard typewriter may operate the linotype machine without previous study or practice and with very little diminution of speed.

It is intended to construct the novel key t board in a slug casting linotype machine to replace the key-board now found on such machines and this may be done even by dispensing with keys at allso long as it is possible to selectively and manually control the operation and intervals of activity of the a particular matrices which will form the char acters desired on the slugs cast. Instead of having to reach far out as on present makes of typesetting machines to depress desiredkeys the novel key-board becomes the real key-board of an existing typesetting machine and reduces to small compass the size of the key-board.

What I desire to claim and secure by Letters Patent is 1. An auxiliary linotype key-board comprising a plurality of spring supported keys, a plurality of magnets associated in staggered relation with said keys, of the main linotype keyboard, an electrical circuit in which said magnets are included, switches controlled by said spring-supported keys, and pivotal.

pushers controlled by said magnets selectively, for depressing the linotype keys.

2. A device asdescribed consisting of a key chines in standard typewriter ashion consisting of an auxiliary key-board surmounting the linotype keys, means attaching said keyboard upon a linotype over the keys of the latter, linotype key depressors normally restin upon the linotype keys, magnets interposed between said depressors and the keys of the auxiliary keyboard for energizing said magnets to selectively control the latter, and circuit closing devices for energizing said magnets controlled by said auxiliary board keys selectively.

4. An auxiliary key-board for linotype machines consisting of a base, a plurality of depressible keys and shift keys arranged in standard typewriter order, springs opposing the depression of said keys, selectively, a-

group of magnets, one associated with each key, means controlled by said keys selectivel for energizing said magnets and lever-shaped pushers associated with said magnets having armatures attracted by said magnets and linotype key engaging parts to depress the lat- 5. In a device as described the combination of a frame, an arcuate shaped plate, contactpins arranged on said plate having electrical connections to a circuit, a bell crank lever having one arm pivoted so as to actually sweep across said contact pins selectively, magnets controlled by the several contact pins when contacted, a key board having keys for depressing said lever, a depending arm on-said frame on which said lever is pivoted, a shaft lever pivoted on the mentioned lever armdepressible from above said keyboard and having an intermediate hook, a

spring con 4 mam *moting both flevers, ..a key board on the shift lever and a slotted plate fixedly mounted in the slot in whiehsaid hook is eons'trainedto engage.

5 6. In combination with a- "base board 3, series of magnets dependingly carried-thereby, a. series of individual detents pivoted fix ediy so as to be attraoted movably by said magnets selectively keg pushers pivotally 10 carried by said detents esigned to rest-upon linatyspe keys, a standard t pewriter set of keysemnged insurmounte vrelationdepressingly upon said base board, and electrical means actuated by said last set of keys sfelec- 15 tively'for-energizing-said magnets selectively.
