12 Claims.

This invention relates to printing and more particularly to typing machines for use in what is commonly termed "oflset printing, and has for an object to provide an improved means and method of preparing print and transferring the same to a printing roll or plate for use in a printing press.

The present method consists in typing the letters or characters to be printed on a strip of Paper or the like, severing the strip to permit to a sheet of paper or other flexible material for reproduction as in the-usual offset. printing operation.

The machine and methodof the present invention is primarily adapted for use in printing shops or establishments where the business does not machine is generally indicated at l and includes a front portion l0 carrying a plurality of type keys H arranged in a generally semi-circular form, the keys being mounted on levers i2 fulcrumed for rocking movement on a series of pivotal rests l3. At their inner ends the levers are pivotally anchored in a slotted member l4, and at this point each key engages a rack bar I! which is shown as mounted for vertical movement in guides i6, II and I8. At their upper ends the rack bars are each provided with teeth l5 which engage gear teeth I! on the inner ends of a series of type bars 20, the latter having on their outer ends type characters 2|. The type bars are mounted for pivotal movement on a curved bearing ring 22, and on their outer ends the said bars come to rest on a cushioned support 23. The key levers l2 are individually actuated against the pressure of springs 24 mounted on pin 24', the latter at its upper end being anchored in cross member 24".

The arrangement of the keys and type bars and the manner in which they operate may be "varied at-will. and'in fact thedeslgn of the majustify the purchase of a Linotype machine, al-

though the machine may be used in the place of or asan auxiliary to a Linotype machine.

The foregoing and other objects and advantages'will become apparent in view of the following description taken in conjunction with the drawings, wherein:

- Fig l'is azview in front elevation of a typin machine embodyingthe invention;

Figs. '7 and 8 are similar .views of coasting spacer members;

Fig. 9 is a perspective view of a supporting and I releasing device for the members of Fig. 8;

Figs. 10 and 11 are details of the transfer sheet indexing mechanism.

Referring to the drawings in detail, and first to Figs. 1 and 2, the typing machine may be pat, terned along the lines of the conventional typewriter and is so illustrated. The frame of the type strip chine in this respect may'follow the'conventional typewriter as above indicated. The typecharacters here 'shown are of equalipoint spacing throughout to simplify the illustration and description'. Each'type bar may 'be'provided'with a multiple of characters brought intdti'ping po-' 3 sition by shifting the bars as a unit.

v Fig. 2 is. an enlargedview' in vertical section" of the machine of Fig. 1; A

The type characters are printed on a strip of V paper or like material (herein termed the line strip) by'theuseof transfer inkg'the saidstrip being severed after each line" has been typed thereon; .'To accomplish this operation, a stationaryplaten 25in the form nt-an elongated bar is provided and is anchored at opposite ends a to the frame ill. 'I'hisplaten25j should be of] alength such as will readily accommodate any reasonable length of line. The line strip is indicated at- 28 and is fed from a reel 21 along the v member 32.

top of the platen, note particularly Fig.3.

An inking ribbon 28 is provided; note Fig. 4,

and is fed'from reel 29 through and over guide 30 and thence on to reel 31, the reels andguide being supported on a suitable bracket or frame The guide 30 is' formed with an opening 33, at which point the. type 2i contacts the ribbon-and make their impression through the latter on the paper; strip. The reels 29 and 3| may be provided with-suitable escapement mechanism whereby the ribbon is fed from one riage by means of flexible cable 39 passed around sheave 40. Return movement of the carriage against the tension of reel 38 may be effected by means of hand lever 4|.

The back of thecarriage 35 is provided with a series of ratchet teeth 42 which coact with ratchet or dog 43 forming part of escapement mechanism including lever 44 having an operative connection with the ratchet 43 by means of adjustable link 45, the lever 44 being actuated by means of lever 45 overlying the inner extremities of the type levers 12 to be contacted thereby each time any one of said levers is actuated.

Within the confines of the members 35' and 35" of the carriage 35 are mounted a series of spacer members -41, one of which is shown in detail in Fig. '1. Each of these members 41 has a wedged-shaped edge 41' which depends downwardly, note particularly Fig. 4. A bearing hole or opening 48 provides means by which the spacer members may be slidably mounted on the guide bar 31.

Each of the members 41 is also provided with a pair of spring fingers 49 which extend upwardly over the platen and are tensioned sufficiently with respect to the strip of paper or line strip 25 on the platen to grip the paper and feed the latter along with the carriage 35 and the members 41.

Means are provided to effect severing of the strip 25 between any word or group of words making up a line of type, such means as herein shown comprising a knife 58, note particularly Figs. 4 and 6, which is mounted for vertical reciprocation in guide 5|. A lever 52 acts to depress the knife 50 against the tension of spring 53, said lever being actuated from the keyboard by means of spring return push button or key 54 conected by red 55, lever 55a shaft 55b and contact lever 550. The entire ribbon-feeding and strip severing mechanism is mounted as a unit on bar 55d which when the knife 50 descends into cutting position is shifted laterally to bring the knife into proper spaced relation with respect to the adjacent typed character by means of cam 554: secured on and rotatable with shaft 55b, said cam acting on supporting bar 55d.

After the respective words which make up a line of type have been typed on the strip 25 and the words severed by the knife 58, there are two actions which take place to justify the line: the opposite ends of the line are positively limited against displacement, and the words within the line are equally spaced within those limits. To accomplish this result, end stops 55 and 55, note particularly Fig. 3, are provided and are adjustably mounted on a bar 51 having a series of teeth 51' therealong to permit adjustment of the members 55 and 55'. The bar 51 is supported at its opposite ends by means of levers 58 and 58' which are mounted on a shaft 55 and at their lower ends are ,provided with cam rollers 58 adaptedito coact with cams 5| mounted on cam shaft 52. The shaft 52 may be operated in any suitable manner, but as here shown, is manually operated by means of key lever 53 which at its inner end is adjustably secured to shaft 54 having secured thereon gears 55 in mesh with f means of spring 51.

Equal spacing of the words within the line is effected by spacers 58, one of which is shown in detail in Fig. 8. Each of the spacers 58 is generally in the form of an L-shaped member having a wedge-shaped leg 58' which is adapted to enter or cam itself between an adjacent pair of members 41. There are approximately as many spacers 58 as there are members 41, so that separation of the words may take place at any desired point. At their upper end the spacers 58 are provided with elongated bearing openings or slots 59 whereby they may be mounted on supporting rod or shaft 15 which at its opposite ends is fixed to the frame I. The lower end of each of the members 58 is provided with a latching projection 1| for a purpose which will presently be described. The string of spacers 58 is held in idle or non-spacing position by support 12, note particularly Figs. 2 and 9. This support may be formed of sheet metal and. is made in two separate parts 12 and 12', each part being formed with a ledge 12" which engages the latching projection H of theL-shaped spacers 58. Within the space between the supports 12 and 12' is mounted a spacer release lever 13 having spring 14 connected to the upper end thereof and a lower contact projection 13. The upper edges of the supports 12 and 12' are rolled or curled to provide abore by which they are mounted on a supporting rod 15, said rod also serving as a pivot or fulcrum for the spacer release lever 13. The lever 13 is located at a point where it will register with the opening 33 in the guide 35, note Fig. 4, so that when the spacers 58 slide along the supports 1212', any selected one may be released and dropped into spacing position between the members 41. To actuate the lever 13 against the tension of spring 14, an arm 15 is loosely fulcrumed on the shaft 54 and is adapted to engage the projection 13' on the lever 13, note Fig. 2. Arm 15 forms a bell-crank connection with lever 15 which extends to the front of the machine and is pro ided with spacer bar 15". Thus, when the spacer bar 15" is depressed, lever 15 is moved counterclockwise as viewed in Fig. 2 and the lever 13 is rocked rearward and releases any one of the spacers 58 which may register with the lever at that particular time during the typing operation.

When the lever 13 is actuated to release any selected number of spacers 58, they drop by gravity into a position between the wedge shaped ends 41' of the members 41. To drive the spacers 58 home, bellcrank levers 11 are provided, note Figs. 2 and 4, and are mounted on shaft 58, said levers being connected at their upper ends by a rod or bar 18 adapted to engage the lower legs 58 of the members 58. The opposite ends of each of the levers 11 are provided with cam rollers 15 adapted to engage cams mounted on the cam shaft 52. Thus, as the lever 53 is depressed, it rotates shaft 52 clockwise through connecting gears 55 and pinion 55, thereby rocking the bellcrank levers upwardly and throwing the bar 18 against the lower surface of any of the spacers 68 which may have been released at that time.

After the line has been justified, the spacers 68 must be returned to their non-spacing position. Accordingly, the spacers which have been inserted between the members 41 are first moved downwardly by a link rod 8I connected at opposite ends to the bell-crank levers 11 and having the intermediate portion thereof adapted to engage the lower legs 68' of the spacers 68. Thus, when the spacer bar 63 is released and cams 88 permit return movement of the bell-crank lever 11, the latter at the same time drops the rod or bar 18 in contact with the legs 68' of thespacers 68 and pulls the spacers outwardly from between the members 41. To move the spacers which have been thus removed from their spacing position back up on the ledge 12, the latter' is mounted to rock on the shaft 15 against the tension of springs 82 and each of the spacers 68 is provided with an upwardly projecting lug 83 which is adapted to be contacted by a pusher bar 84, see Fig. 2, which in turn is actuated by means of push button 85 connected to said pusher bar by means of rod 86 against the tension of spring 81.

As heretofore indicated, the method of printing for which the machine is particularly adapted is known as offset printing, wherein the typed matter is reproduced by photographing to a suitable plate for use in a printing press. In the present instance, the line of type after being justified, is transferred on to a sheet of paper ready for the photographing process. To transfer the line of type to the sheet of paper, transfer ink is used for the ribbon 28, and the paper or transfer sheet or web to which the individual lines are transferred is mounted on a reel 88, the latter in turn being rotatably mounted on shaft 88 supported in bearing brackets 98 from the frame of the machine. The transfer sheet as it passes from the reel is indicated at 9|, and this sheet passes around idler r011 82 and then beneath press bar 83 and then passes between indexing roll 84 and tension roll 85. The marginal edges of the paper are perforated in accurately spaced relation, and indexing wheels 86 are adapted to engage in these perforations, note Figs. 2 and 10. These indexing wheels are intermittently actuated by pawl and ratchet mechanism 81, Fig. 11,

which mechanism is in turn actuated in a manner which will presently become apparent.

The press bar 83 directly overlies the platen 25, and this bar is supported at opposite ends frombrackets 88 each having a head 98' at its upper end, the said brackets 98 being slidable in guide lugs 88 projecting outwardly from the main supporting brackets 88. Springs I88 are interposed between the heads 88' and guide lugs 88 so that the bar is depressed against the tension of said springs.

To depress the bar 83 and in turn press the paper against the line of type, cams I8I are provided and are adapted to actuate levers I82, there being one at each side of the machine, said levers extending upwardly and at their upper ends being provided with fingers or arms I83, said arms I83 together with the levers I82 forming bell-cranks which are fulcrumed on shaft I84 on which the indexing wheels 86 are also mounted. It will be noted that the cams I8I are mounted on the cam shaft 62, so that when this shaft is rotated through lever 63 and gears 65 and 66, the press bar 83 is depressed. When the lever 63 is released and the shaft 62 rotates in the opposite direction, the pawl and ratchet mechanism 81 is caused to engage the indexing wheels 86 and advance the sheet of paper 8|.

Whenever a spacer 88 is released into spacing position, the escapement for the carriage must also be actuated. Accordingly, the lever 16 is provided with an extension I85 adapted to engage lever I86 fulcrumed on shaft 62, said lever at its rear end engaging an extension I81 of lever 44. Thus, when the lever I86 is actuated, it in turn pulls down on the link 45 which actuates ratchet or dog 48.

A general description of the operation of the machine follows:

As heretofore noted, the machine isparticularly adapted for use in offest printing, and the ink used for the ribbon 28 is of the transfer type whereby the characters typed on the line strip :I: may be transferred by contact to the sheet The line strip 26 is first inserted between the top of the platen and the spring fingers 48 of the members 41. The machine is now ready to be operated in a manner similar to the ordinary typewriter. After each word has been typed, the knife 58 is depressed into cutting position to sever the line strip by means of the push bar 55 and push button 54. Thus, when the complete line is typed, the line strip will be severed between each word.

Each time the strip is severed, one or more of the line spacers 68 is released (depending upon the width of the space desired) by depressing bar 16" and actuating lever 16', the released spacer dropping and swinging forwardly so that its leg 68' is directly below the line of members 41 ready to be moved up into spacing position between any adjacent pair of said members. After the line has been typed, the line strip severed between each respective word and the spacers 68 thrown into position, lever 63 is depressed to rotate cam shaft 62 and the bar 51 is rocked inwardly bringing the end stops 56 and 56' into position at opposite ends of the line and the spacers 68 are moved upwardly between their meeting spacing members 41, so that the spacing of the words of the line within the end stops is equal throughout the line.

Fig. 3 shows a line of type which has been justified, the stops 56, 55 and the spacer members moving back to idle position.

After the line is justified, the press bar 93 descends and presses the transfer sheet or web 9| against the print or characters which have been typed on the line strip by means of the transfer ink used on the ribbon 28. The sheet or web 8| is advanced one step each time a line has been typed, justified and transferred.

The machine is capable of turning out a large amount of work in a relatively short time, and does not require a skilled operator other than one capable of using a typewriter. Each line is accurately and positively justified and once the line has been transferred to the transfer sheet. the strip of paper on which the characters are printed may be discarded. Thus, the machine does not require expensive and bulky materials.

It will be understood that the machine shown in the drawings and described in the specification is simply for the purposes of illustrating the invention, and that refinements and changes in construction and design may be adopted to carry out my improved method without departing from the spirit or scope of the invention as defined by the appended claims.
