Specification of Letters Patent.

Patented Nov. 11,1919.

Application filed April 28, 1919. Serial No. 293,372".

T 0 all whom it may concern."

Be it known that we, ARTHUR Jeans POLLEY and Frlnonnion Gnonen Cnnnn, subjects of the King of Great Britain andIreland, residing, respectively, .E'arlswood, in the county of Surrey, England, and Greydon, in the county of Surrey, England, havev invented Improvements in Type-Setting and Printing Machines, of which the following is a specification. I

This invention relates to apparatus de-- signed to reproduce in ordinary printed characters, columnwise, .messages or intelli-' gence (hereinafter referred to for brevity as words) transinittedin the form of electric impulses or which have been so transmitted andrecorded as perforations in a tape. 1

In some kinds of apparatus of the last mentioned kind. the tape is perforated on: what is known as the five unit system and in other kinds of such apparatus, the tape is perforated on the \Vlieatstone Morse system.

Examples of apparatus of the last men tioned kind are described in the specifications of former British Letters Patent No. 22653 of 1902, No. 25861 of 1905, No. 3999 of 1907 and No. 1947 of 1908, granted to F. G. Creed and IV. A. Coulson, but in these cases, the type carrying devices are each provided with only one ordinary type character, and only one ordinaryv type character is printed at one time.

Now't-he present invention has for its obect to n'ovide 1m Jr'oved a 3 aratus ada ted to be operated orcontrolled by electric iin-.

pulses, or by perforated tape, whereby ordinary type characters are selected from a magazine and assembled into a line of type which is then moved to a printing position prior to the type being broken up and redistributed.

Printing mechanism according to the in vention may comprise a mult1channeled type magazine containing the different kinds of type to be used and'also spaces (hereiir after included in the term type), type releasing or ejecting mechanism operated by or under the control of type selecting levers v and adapted to permit selected typeto pass of type, means for transferring a line of type from the assembling-insane to the said carrier, a platen for carrying a sheet of paper upon which the line of type is caused, to print a lineof words, means such as an inking ribbon or roller, for causing the line of type to produce an impression on the sheet: of paper, means for moving the platen with sheet of, paper relatively to the, line of type so as to cause the latter to print a line of words on the sheet of paper, means for'feeding the sheet of paper endwise so that suecessive lines of words can be printed in column form thereon, type'distributing mecha nism arranged above the magazine, carrier transferring means whereby the carrier With the line of type carried thereby, can, after it has printed a line of words, be brought into a position for the line of type to be transferred-to the type distributing mechanism, means for transferring the line of type from the carrier to the distributing mechanism, and motor operated mechanism for actuating, at the required times, the various parts of the printing mechanism necessary for effecting the above mentioned operations.

Printingmechanism embodying the invention can beconstru'cted in various forms andthe parts, thereof be arranged in various ways to effect-the required result, and, as before indicated, he used in connection with various constructions of electric impulse or perforated tape controlledapparatus of the class hereinbefore referred to.

In the accompanying illustrative drawings, Figure 1 shows in front elevation and Fig. 2 partly in plan and partly in horizontal section one construction of column printin elevation and partly in cross section the left hand end of the apparatus and 4e shows partly in elevation and partly in cross section the right hand end of the apparatus. i

This printing apparatus is shown associated with selective apparatus of the kind herein referred to, for operating the type selecting levers used in the present invention. I

F 5 shows in plan, part of the type assembling means. Figs. 6 and 7 are sectional detail views at right angles to one another showing clutch mechanism for temporarily connecting a cam shaft to a constantly run ning secondary driving shaft. Fig.8 is a plan and Fig. 9 a perspective View showing apparatus for use in connection with the mechanism for controlling the clutch mechanism shown in (3 and 7 Fig. 10 shows in face view a tvpe-plate. Fig. 11 is a simi lar view of a space plate. Fig. 12 is a section of one of these plates taken on the line 00 a? of Fig. 11.

In the examples shown, and referring more particularly to 1, 2 and 3, A is the magazine for holding the different kinds of type to be used in reproducing, in ordinary characters, messages or intelligence received as electric impulses, or in the form t of perforations in a tape. B are the devices,

paper holding, feeding and printing mechanism is shown at 1), both at the bottom of the machine. The mechanism for distributing the type, comprising each line of type, back into the magazine, after being used for printing, is shown at the top of the apparatus at E. The mechanism for transferring each line of type, after use, from the line of type assembling mechanism at C back to the type distributing mechanism at E, (Fig. 2) is shown at G.

In the particular example of column printing apparatus shown, such apparatus is assumed to be associated with apparatus of the type described in the specification of said British Letters Patent No. 19%? of 1908 granted to F. G. Creed and V7. A. Coulson for reproducing, in ordinary characters, telegraphic or other messages or intelligence in the form of perforations in a tape. Such apparatus is hereinafter called for brevity, the Creed selective apparatus. In the apparatus now being described, the type selecting levers B correspond. to the levers 9 used for actuating the type carrying levers (4 shown in the drawings of the said former specification and are raised by the pistons of pneumatic motors the cylinders of which are formed by holes H (Fig. 2) formed in a block I, the piston rods of the motors being shown at J. Compressed air is admitted to the motor cylinders and released therefrom, by slide valves operated and controlled in the manner, and for the purpose described in the said former specification and further description thereof here will therefore be unnecessary. K is the main driving or cam shaft of the Creed selective apparatus. It is to be clearly understood however that devices corresponding to and having the function of the type selecting levers B, can be associated with and be actuated by apparatus other than the Creed selective apparatus and though they may advantageously be associated with such apparatus, such devices are not limited to use therewith.

Associated with the driving shaft K of the Creed or other selective apparatus used, is a main driving shaft M and a secondary driving shaft N. The shafts K and M are geared together through bevel gearing O and P and connecting spindle B so as to rotate simultaneously at the same speed, and either of them may be driven from a motor, for example an electric motor, through a driving wheel S fixed to one of them, for example, the shaft M as shown. The shaft N is driven from the shaft M through worm gearing F. From these shafts K, M, N, the various movable parts of the column printing mechanism, which will now be described, are actuated as and when required, the shafts and other parts being mounted in suitable stationary bearings, and standards, indicated generally as T, carried by a base plate V.

The magazine A to contain the differentkinds of type, is a 1m1lti-channeled magazine similar in construction to that used in other machines, as for instance that used in line of type casting machines, the magazine being arranged vertical with the type receptacles a (Fig. 8) therein, in a straight row and terminating at their lower ends at a suitable distance above a funnel shaped guide 7) (Fig. 1) having a doubly inclined bottom or support 0 upon which released type fall, one at a time, and pass to the type assembling means. The guide I) may conveniently be divided, as shown, by curved ibs (Z into a number of channels 6 of diflerent lengths extending from the lower ends of the type receptacles a and converging toward a centrally arranged outlet or guide channel 6 below which is the type assembling means. The type, as shown in Figs. 10, 11 and 12, are each in the form of a flat plate 7' (hereinafter called a type plate) notched at its opposite vertical edges, as shown, at 7, so as to leave upper and lower lateral flanges or projections f and f respectively, that are of less thickness than the rest of the plate. In the case of a type plate that is to print a character, (see Fig. 10), the upper lateral flanges f are cut away at 7' for a purpose hereinafter described,

and the type character is formed on the bot-' tom of the plate at g. In the case of a type plate that is to form a space, (see Fig. 11), the lateral flanges f retain their width from top to bottom, for a purpose hereinafter described, and the bottom of the plate is grooved as shown at 72, so that it will make no impression on paper. pressed against it. In the upper portion of each type plate is a V shaped notch ithe opposite edges of which are formed with a number of ribs and recesses 2' that are differently shaped or arranged for different type plates, similarly to the type plates used in line-oftype casting machines, for the purpose of enabling the difierent type plates to be readily distributed, after being used for printing, back into the magazine receptacles a.

The type plates f are arranged one above another in their respective type receptacles a and their descent in such receptacles is controlled by corresponding escapement devices by means of which they are allowed to fall, one at a time, and pass to the type assembling means. For this purpose, each escapement device may be adapted, when in one position, normally to engage and hold the lowermost type plate in the corresponding receptacle and thus to support the whole column of type plates in that receptacle but when moved into another position by its corresponding selective type lever, it will engage andv hold the next upper or penultimate type plate and release the low ermost type plate and when moved into another position, it will release the penultimate type plate, which now becomes the lowermost type plate, and reengage and hold it when it assumes its lowest position in the receptacle.

In the arrangement shown for this purpose, each escapement device comprises a two armed lever (see Figs. 3 and 4) moimted to turn in a vertical plane about a horizontal spindle m and provided at its upper and lower ends with horizontal pins 0 and p jointed to the said lever. The lever is normally held in a position in which, as shown in Fig. 3, the lower pin p extends into the notch f in one side of the lowermost type plate f (Figs. 10 and 11) and engages the lower side of the upper end wall of the notch in the plate. The upper pin 0 of the escapement lever is is similarly arranged opposite the notch f in one side of the next adjacent upper type plate 7 but does not extend into such notch. The escapement lever is suitably connected, as by a link 1 to the associated selective type lever B. This lever is mounted to turn upon a spindle 2i and is actuated by the piston and piston rod J of a pneumatic motor the cylinder H (see Fig. 2) of which is formed in a stationary block I as hereinbefore described. Each selective type lever B and associated escapement lever 70 are normally held in the position shown in Figs. 3 and 4 by a spring u. o is a vertical comb shaped plate for separating and guiding the horizontal end portions of the selective type levers B. The arrangement is such that when a selective type lever B is operated in one direction by its pneumatic motor H-I, un der the action of the selective mechanism of the electric impulse or perforated tape controlled machine to reproduce a charac- 7 type lever B returns to its normal position,

under the action of its spring a, the es:

capement lever 70 will be moved in the opposite direction into its normal position in' which its upper pin 0 will release the type plate with which it was engaged and allow this plate to fall, and will simultaneously move the lower pin 9 into a position to arrest and hold the said plate in the lowermost position until the corresponding selective type lever B is again actuated when the above described operations of the escapement lever 70 will be repeated toagain release the lowermost type plate.

The line of type assembling means comprises, according to the arrangement shown, the vertical channel 6, the bottom 6 of which forms a support for each type plate 7 falling on to it, a stationary horizontal bar 1 of V shape in cross section, at its lower part which is formed on its opposite side with ribs and grooves 1 adapted to fit the grooves and ribs in the edges of r the V shaped notches 2' (Figs. 10 and 11) of the type plates f, and a pair of horizontally movable pins 2 carried by a crosshead 3 and arranged to work through holes in the side walls of the channel a and act upon a type plate 7 therein and force it laterally on to the V shaped portion 1 of the bar 1. The cross head 3 is arranged to slide between stationary guide bars 4 and is reciprocated by a rod 5 from acrank disk 6. This disk is fixed on the main driving shaft M so that it makes one rotation for each rotation of the main driving shaft K of the Creed selective apparatus. The type plates 7 as they are assembled are gradually moved along the bar 1 and are finally arrested by a movable stop 7, (Fig. 2) thus forming a line of type as shown at f, (Fig. 1) that may be of a given maximum length, or of less length, before they are used for the printingof a line of ordinary characters on a sheet of paper, the type characters being on the bottom of the type plates as shown at g in Fig. 10. The line of type plates are pressed against the movable stop 7 by a pusher com prising, in the example shown, a pair of spring fingers 8 carried by a stirrup shaped carrier 9 arranged to slide on the horizontal bar 1 and to be moved to and fro thereon by two flexible connectors 10 and 11 respectively connected to opposite sides thereof. The connector 10 is led around guide pulleys 12 and connected at its other end to a winding drum 13 (Figs. 1, and 4) mounted to rotate on the main driving shaft M and driven therefrom through a friction clutch one member 1a of which is connected to the drum 13 and the other member 11 of which is mounted to slide endwisc on a tubular extension l-l of the member 1% and is connected to an endwise movable grooved collar 15 keyed or feathered to the shaft M so as to rotate therewith. The clutch member 1% is moved toward and from the clutch member 11 by a clutch lever 17 fixed on a rock shaft at 1T that is provided with a. lever arm 1'7 connected to one end of a link 18 the other end of which is connected to a swing arm 19 pivoted at 20. The link 18 is provided with a roller 21 extending into a cam shaped groove 23 formed in one face of a disk 2% fixed on a slow moving cam shaft 27 (Figs. 6 and 7) that is arranged co-axial with and to the shaft N. The connector 11 is connected to a spring drum 25 the coiled spring of which is arranged within a fixed casing 26.

The cam shaft 27 is rotated at determined times from the constantly rotating secondary shaft N for operating the cam disk 2% and other cams fixed thereon and hereinafter described. For this purpose upon one end of the shaft N is fixed a ratchet wheel 28 and upon the adjacent end of the cam shaft 27 is fixed a plate 29 upon which is pivoted at 29 a clutch lever one arm 30 of which is formed with a tooth 30" and the other arm 31 of which is normally held in the position shown in Fig. 7 by a catch 32 mounted on a spindle 33 and provided with a spring tongue 3a. The arrangement is such that normally the clutch lever 30 ant 31 is held in the inoperative position shown in Fig. 7, against the action of a spring 36 but when the catch 32 is momentarily lifted, as hereinafter described, the clutch lever is released and its toothed arm 30 caused to engage the ratchet wheel 28 so that it and the plate 29 and the cam shaft 27 are caused to make one revolution at the end of which the lever arm 31 is again arrested y the catch 32, the lever arm 30 disengaged from the ratchet wheel 28 and the cam shaft 27 stopped until the catch 32 is again lifted, when the described operations are repeated. 35 is a back stop on the plate 29 for the lever arm 31. The spring tongue 3% serves to retain the said arm 31 in the catch until the latter is lifted.

The catch 32 is lifted, for the purpose described, each time the full number of type plates 7 have been assembled on the assembling bar 1, to form a line of type plates of maximum length. For this purpose there is mounted on a shaft 37 carried in stationary bearings 37, (see Figs. 8 and 9) a ratchet wheel 38, the number of teeth on which corresponds to the predetermined number of type plates required to form. a full line of type, say fifty five, in a printed line of ordinary characters. Engaged with this ratchet wheel is a pawl 39 carried by a lever arm 4:0 by a boss 11 mounted to rock on the shaft 37 and provided with another arm The outer end of this arm is connected by a link l3 to a bell crank lever arranged to be oscillated about an axis at ilby a rotary cam a5 on the main driving shaft K. The arrangement is such that the ratchet wheel 38 will be fed forward one tooth for each rotation of the driving t K and therefore for each type plate 7' red on to the assembling bar 1. G11 one face of the ratchet wheel 38 is a tooth 16 arranged to engage one arm $7 of a bell crank lever pivoted at t8 and the other arm f7"- of which is arranged to lift a bar 9 each time the ratchet wheel has moved through a distame corresponding to the whole of the teeth thereon, say fifty five teeth. 50 is a detent pivoted to a fixed part of the apparatus and engaged with ratchet wheel 38. The bar i9 is provided with a projection or tappet 51 adapted, when the bar is raised, to engage a projection 32 on the pivoted catch (Figs. 6 and 7) and thus to raise the catch and to release the clutch lever 30 31 to enable it to ch nge the ratchet wheel 28 and cause the cam shaft 2? to be rotated from the secondary shaft N through one revolution. The catch 32 will then disengage the clutch lever 3031 from the ratchet wheel 28, whereupon the (am shaft will be stopped and remain at rest until the catch 32 is again lifted after another revolution of the ratchet wheel 38. To prevent the bar as falling too quickly, that is to say before the catch 32 has properly released lever 3031, there is pivoted to the bar l9, a stop 52 in the form of a lever, one arm of which, under the action of a spring 53, is caused to rest upon a fixed support 54:, when the bar is raised, and which is afterward disengaged from the said support by a pin :5 on one end of the cam l5 to allow the bar to fall into its normal position.

hen it is desired to enable the cam shaft 7 to be connected to the secondary shaft Y before the ratchet wheel 38 has completed full revolution corresponding to a full ength line of type plate, as for instance when it is desired to print an address containing a less number of type characters than that in a full length line of type, or a short line of characters, the bar #19 is lengthened as shown in Fig. 9 and connected to a special selecting lever 13 adapted to be operated by what is known as a RT, or SN signal, or other signal in the perforated type dealt with in the Creed or other selective apparatus used, for indi- *ating a short line. In this case the pawl 39 and detent 50 are provided with extensions 39" and 50 respectively that take into recesses t9 and at9 respectively in the bar 49 so that when this bar is lifted by the special selecting lever B, the pawl and detent are disengaged from the ratchet wheel 38 which, in each case, is .caused to return, under the action of a spring in a stationar spring drum 55, to an initial starting position that is determined by an arm 56 connected to the ratchet wheel coming into contact with a fixed stop 57. The same action will also take place when the bar 49 is raised by the lever al7a'c7 under the action of the pin l6 on the ratchet wheel 38. 1

Also, in this case the bar as is made in two lengths the lower of which is normally held on the arm M of the lever 47l7 by a pawl 47 carried by one end of a rod 48 and arranged to bear upon a shoulder l9 on the said lower part of the rod as. The rod 48 is arranged to slide endwise in a stationary bearing and is'formed with a slot as through which extends a pin %8 carried by the lever arm. 47 to which the sec ond end of the rod l8 is connected by a spring 48. The arm an in this case is, as

shown, preferably made as a spring blade.

With this arrangement the upper part of the rod 49 can be raised by the special selecting lever B for the purpose mentioned,

without raising the lower part or affecting the lever l7%" and attached parts. WVhen however the wheel 38 makes a complete revolution and causes the tooth 46 to act against the lever arm l7, it will stress the spring blade arm 47, until the pin 48 on the arm l7, by-acting against one end of the slot 48, moves the rod and pawl 47 out of engagement with the shoulder a9 on the lower part ofthe rod whereupon the whole rod is caused to rise quickly and close theclutch on the shafts N and 27. This mechanism is hereinafter sometimes referred to collectively as type counting mechanism.

lVhen the cam shaft 27 is rotated by the shaft N as described, the cam disk 2% will act through the link 18 (Fig. 4) to close the friction clutch M ll so a to rotate the winding drum 13 and wind up the flexible connector 10 so as to move the carrier 9 along the type assembling bar 1 along which it is guided by lateral pins 9" working in grooves 1 in the bar, and cause the pair of fingers 8 to act upon the flanges f of the rearmost space plate f on the bar and force the line of type plates firmly against the removable stop 7 and hold it. in' position for printing, the said friction clutch 14l1l"- then slipping. 1

58 is a printing roller for supporting a sheet of paper 59 below the line of type plates at 7" held on the bar 1 (Fig. 1) in readiness for printing. The roller is carried in hearings in the forked arm 60 of a lever pivoted at 60 and the other arm 61 of which is arranged to be depressed, at the right time, by a cam 62 fasten the cam shaft 27 so as to raise the printing roller paper 59 is drawn from a roll 63 thereof over the printing roller 58 and under guide rollers 6t and upward over a fixed support 65 so that the line of printed characters can be readily seen and read. For feeding the sheet of paper forward, it is provided at intervals along its edge with holes to engage corresponding pins 66 on the printing roller 58 which is rotated through a small angle by a pawl .67, each time it ismoved downward by the lever arm 60, the said pawl 67 being pivoted to part of the fixed support T and engaging a ratchet wheel 67*" on the roller. Backward rotation of the printing roller is prevented by a detent- 68 pivoted to the lever arm 60.

The type-characters on the lower ends of the type plates may be inked by passing over the periphery of inking wheels 69 as they are fed along the bar 1. Or an inking ribbon may be arranged between-the printing roller 58 and the line of type plates f when this is held'in the printing position f against the removable stop 7. The removable stop 7 is withdrawn from the line of type plates, after the printing operation, by arms on a link 7 O operated by a lever arm 71, that is fixed on a spindle 72' to which is also fixed another lever arm 73 carrying a roller that extends into a suitably shaped cam groove 74- in one side of a cam disk 74lfixed on the cam shaft 27. j

lVhen the stop 7 is withdrawn, after the printing operation, the friction clutch 1414awhich had been slipping will at once come into action again and move the line of type plates endwise to a farther extent sufficient to transfer it from the assem- .bling' barrl, to a vertically movable carrier 7 6 (Figs. 1, 2, and 3), by which it is transferred to a position to be delivered to the type distributing mechanism'at E. The carrier 76 is a bar of V shape in cross section and formed on its opposite sides with ribs and grooves76 adapted to fit the grooves and ribs in the edges of the V shaped notches 2' in the upper edges of th type plates f. This carrier, when held in its lowermost position, is in line with the V shaped recesses z' in the line of type plates f carried by the assembling bar 1 so that these platescan, after printing, be pushed off the bar 1 and on to the carrier 76 so as to be left'suspended from the latter.

In the arrangement shown, the mean used for transferring each line of type plates from the assembling and printing position to the distributing position, comprises a pair of vertically arranged intermittently operated endless bands 77 that pass over and under upper and lower pairs of pulleys 78 and 79 fixed on shafts 80 and 81 respectively and to which are attached, transversely, a number, conveniently three, of type carriers 76 of th kind hereinbefore described. The arrangement is such that in each of three positions of the pair of belts there is a carrier 76 in the lowermost position opposite the type assembling bar 1, another opposite the supporting bar 82 of the type plate distributing mechanism at E, and another at an intermediate position, on the descending side of the bands 77.

The bands 77 are provided with holes 84 for engagement with spaced projections 85 on the band pulleys 78 and 79 to keep the latter in register. The shaft 80 for the up per pair of pulleys 78 is arranged to be driven through a friction clutch (see Fig. 2) one member of which, namely 86, is fixed to the shaft 80 and the other member 87 of which is mounted to turn on the shaft. The clutch member 87 is constantly rotated from the main driving shaft K through a pulley 89 and a cross belt 91 and is constantly pressed against the first member 86 by a coiled spring 86*. The arrangement is such that the conveyor bands 77 and pulleys 78 and 79, can be held stationary, when required, without stopping the clutch member 87, the clutch then slipping and can, when released, be again set in motion through the said clutch 8687.

For arresting the endless conveyer 77 so as to hold one carrier 76 in line with the assembling bar 1 to allow of the transfer of a line of type plates from this to the said carrier and to hold another carrier 76 with a line of type suspended therefrom in line with the stationary bar 82 of the type distributing mechanism at E, there is provided in the arrangement shown, a bell shaped stop lever 92 pivoted at 92 and the upper end of which can be moved, at the required.

time, into a position below an empty intermediate carrier 76 to arrest the downward movement thereof and attached parts for the desired period. For this purpose the lever 92 is connected by a link 93 to a lever arm 94 pivoted at 94: and arranged to be raised by a cam disk 95 fixed on the cam shaft 27. The movement of the stop lever into its inoperative position is also effected by the cam disk 95.

The type plate distributing mechanism shown at E comprises the stationary supporting bar 82 which is of V shape in cross section and formed with longitudinal ribs and grooves adapted to engage the notched or toothed sides of the V-shaped recesses i in the upper ends of the type plates f, the ribs on the bar being cut away at different parts of their length in order to adapt them, in the known way to release each type'plate when it is brought over its proper receptacle 0 in the magazine A. The type plates are moved along the supporting bar 82 by a pair of constantly revolving screws 96, arranged horizontally at opposite sides of the supporting bar 82, and above the magazine and engaging the opposite edge portions of the type plates f. The screws may advantageously be made of increasing pitch from left to right (Fig. 1) so as to separate the type plates from each other, as they travel along the supporting bar 82, to facilitate their falling clear of the screws at the required time. In the example shown, the two screws are geared together by toothed wheels 97 and one of them is driven from the main driving shaft K through pulleys 98 and 99 and an endless driving band 100. Below one of the screws 96 is another screw 96 to engage the lower portion of the type plates 7", to support and guide them laterally.

The means used, in the apparatus shown, for transferring a line of type plates f from each carrier 76 to the supporting bar 82 comprises a block 101 mounted to slide on stationary horizontal guide bars 102 and to be moved to and fro by two

flexible connectors

103 and 104. The connector 103 is arranged to pass around guide pulleys 105 and to be wound up by a spring drum 100; the connector 104 passes around a guide pulley 107 and is arranged to be wound up by a winding drum 108. This drum 108 is driven, at the requirec time, through bevel gearing 109 and one member 110 of a toothed clutch from the other clutch member 111 w iich is feathered on a shaft 112 which extends freely through and supports the clutch member 111 and corresponding clutch member 110 and bevel wheel 1.09. T he shaft 112 is the one constantly rotated from the main driving shaft K through pulleys 98 and 99 and the endless band 100. The clutch member 111 is normally held in the open position by a clutch lever 116 under the ac tion of a spring 117. It is moved endwise into the closed position,lto rotate the winding drum 108, by an electro-magnet 118 the circuit of which is closed at the required time by the insertion between a pair of spring contact fingers 119 of a circuit closing or switch contact 120, the electro-magnet being arranged to attract the free end of the clutch lever 116 which is adapted to act as an arn'lature. The switch contact 120 is withdrawn from the fingers 119 to open the circuit and permit the clutch lever 116 to open the clutch 110'111 under the action of'the spring 117 when it is desired to stop the winding drum 108. 116 is a stop for the clutch lever. The movable switch. contact 120 is carried by a switch lever 121, that is pivoted at 1:22 and is arranged; to be moved into the circuit closed position by a pusher 123 fixed to the slide block 101 and into the circuit open position by a tappet 12 1 fixed at a suitable point in the length of the flexible connector 10%. The switch lever is normally held supported by a jockey pulley 125, in each of the positions into which it is moved.

To enable the spring drum 106 to come into action to move the slide block 101 to the right (Fig. 1), only when a carrier 76 with a line of type and plates 7' suspended therefrom comes into correct alinement with the stationary bar 82, the slide block 101 is normally held in its left hand position by a lever catch 126 pivoted to a stationary support 127 and adapted normally to engage with a notched part 128 of the block under the action of a spring actuated pin 128 carried by a fixed support 129. The catch 126 is arranged to be disengaged from the block 101 to release the same, by a pin 130 that is arranged to be moved endwise through a fixed support 131 by the adjacent end of each carrier 76 when such carrier comes into correct alinement with the stationary bar 82. The arrangement is such that normally the block 101 is retained in its left hand position (Fig. 1) against the pull of the spring drum 106 by the catch 126. Vhen an ascending carrier '76 comes into correct alinement with the supporting bar 82, the catch 126 is tripped by the pin 130, under the ac tion of the carrier. At the same time the motion of the endless conveyer bands 77 with carriers 76 thereon, is arrested by the bell crank lever 92 being brought into the path of the descending intermediate empty carrier 76 (Fig. 3) through the action of the cam 95. The spring drum 106 then acts through the flexible connector 103 to move the block 101 to the right, and force the line of type plates off the uppermost carrier 76 and along the horizontal bar 82 and into engagement with the distributing screws 96 by which they are moved over the receptacles a in the magazine A into which the types fall when brought over their proper receptacles and thus distributed for re-use. hen the block 101 has moved the last type plate f in the line of type plates into a position to be engaged by the screws 96, the pusher 123, by acting on the switch lever 12]. forces the movable contact 120 between the contact fingers 119 and thus closes the circuit of the electro-magnet 118. The lever 121 is then held in the operative position by the jockey pulley 125. The magnet by then acting on the clutch lever 116 closes the clutch 110111 and thus brings the winding drum 108 into action to wind up the flexible connector 101 and return the block 101 to its initial left hand position in which it is again held by the spring actuated catch 126. At this moment the tappet 12% on the said flexible connector 104 acts against and moves the switch lever 121 into its open position thereby withdrawing the movable contact 120 from between the spring contact fingers 119 and demagnetiz-ing the electro-magnet 118, thus permitting the spring 117 to open the clutch 110111 and slipping the winding drum 108. The switch lever 121 is then again held in its open position by the jockey pulley 125.

The operation of the whole apparatus is as follows:Assuming the Creed selective apparatus to be in action, then type plates 7 will be released one at a time from the receptacles a in the magazine A by the type selective levers B and allowed to fall into the guide channel 6 from which they will be forced by the pushers 2 on to the stationary assembling bar 1 until either a full length line of'type plates, or a less length of line of type plates, has been assembled thereon, according as to whether the ratchet wheel 38 has been allowed to make a complete rotation without the operation of the special selective lever B or has been allowed to make less than a complete rotation by the operation of this special lever as hereinbefore described. In either case the clutch lever 30-31 (Fig. 7) is released by the catch 32 and the cam shaft 27 rotated through one revolution from the secondary shaft N, whereupon the clutch lever is moved into the inoperative position by the said catch 32 and the cam shaft 27 brought to rest. During the rotation of the cam shaft 27 the cam disk 2% acts, as hereinbefore described, to close the

friction clutch

14, 14 and cause the winding drum 13 to wind up the flexible connector 10 and thereby move the pair of spring fingers 8 to the left (Fig. 1), the said fingers acting against the flanges f of the real-most space plate f on the assembling bar 1 and forcing the line of type plates f on this bar forward into the printing position and against the movable stop 7 by which itwill be arrested. The friction clutch lit-14 although still closed will then merely slip idly. Should the type characters g on some of the type plates at the right hand or rear end ofthe line of type plates form an incomplete word. the fingers 8 will pass idly through the notches i (Fig. 10) in the flanges f of the said type plates until they meet the unnotched flanges f (Fig.11) of the rearmost space type plate 7 and act against the same to force such type plate and the character type plates in front of it forward against the movable stop 7. In this way the line of type plates 7 forced into the printing position will form only complete words.

The cam 62 and lever 60-61 will then come into action to raise the printing roller 58 against the action of the spring 62" to bring the sheet of paper 59 thereon against the line of type characters 9 at the bottom of the line of assembled type plates f to print a line of ordinary characters on the sheet. The cam 62 then releases the lever 6061 and allows the printing roller 58 and sheet of paper to descend under the action of the spring 62 and is at the same time rotated forward a step by the pawl 67 to bring the sheet of paper into position to receive the next line of printed characters The movable stop 7 is then with drawn from in front of the line of assembled type plates 7 by the cam disk 74: whereupon the still closed friction clutch 141:14 which had been slipping, again acts to rotate the winding drum 13 and further wind up the flexible connector 10 to a sufficient extent to cause the fingers 8 to push the line of type plates off the assembling bar 1 on to the lowermost carrier 76 which at this time is held in alinement with the said bar by the stop lever 92 which at this time is held in its operative position by the cam 95 so as to act against the underside of the empty intermediate carrier 76 (Fig. 3) that is on the descending side of the endless conveyor bands 77. The cam disk 95 then acts to withdraw the stop lever 92 from below the said intermediate carrier 76 and the friction clutch S687, which had previously been slipping, will act to drive the shaft 80 and operate the endless conveyer bands 77 to lift the lowermost carrier 7 6 with line of type plates thereon, to a position opposite the supporting bar 82 and the carrier 76 that was previously the intermediate empty carrier, will have been brought into its lowest position in alinement with the assembling bar 1. During this motion the cam disk 95 will move the stop lever 92 into the operative position shown in Fig. 3 in which it will again arrest the endless conveyer bands and hold the three carriers 76 in the positions mentioned, the friction clutch S 687 again slipping idly. The cam shaft 27 carrying the

several cams

24, 74, 62 and 95 having made one revolution will be unclutched from the secondary shaft N. When the carrier 76 with the used line of type plates thereon, reaches its uppermost position in line with the supporting bar 82, the slide block 101 will be released by the operation of the catch lever 126 and the line of type plates will be moved along the said bar to the type distributing mechanism and distributed into the type plate receptacles a in the magazine A in the manner herei-nbefore described. Meanwhile a fresh line of type plates f will have been assembling on the bar 1 until the catch 32 (Fig. 7), under the action of the toothed wheel 38, or special selective lever B a ain. releases the clutch lever 239 31 and again. connects the cam shaft 27 to the secondary shaft N when the above described operations will be repeated to print another line of words on the sheet below the first line. In this way successive lines of words can be printed in a column on the sheet of paper.

As will be obvious, the details of construction can be variously modified without departing from the essential features of the invention.

Also it will be obvious that instead of printing successive lines of ordinary characters by the lines of type on paper or like material as hereinbefore described, the lines of type can be used to impress successive lines of ordinary characters in a sheet of flong from which a stero plate can be cast for use in printing on paper.
