This invention relates to type casting machines of the kind capable of use for the production for stock of type pieces bearing each a single character or representation only, a matrix having as many forms as the maximum number of characters required to be produced being movable in two dimensions to bring individual forms one at a time into position for the casting of a predetermined number of type pieces successively therein, the casting being interrupted with the termination of the casting of each set of type pieces of like character (i. e. in one form) and said pieces being fed as they are cast into a line channel in which some at least (according to the number in a set) of said pieces remain at the termination of a corresponding casting operation, pieces which do not remain in said channel simply falling one by one by gravity as they reach the end of the channel. The usual line hook, which functions at the termination of each casting operation, does not move the more recently cast pieces far enough along the line channel to enable them to fall clear of the latter and, therefore, not only the placing of the sets of type characters in the corresponding or appropriate compartments of the usual type cases or compositors trays, but also the removal of those pieces of each set which remain in the line channel at the termination of that casting operation which produced them has heretofore been efiected manually.

As is well known in machines of this kind, the positioning of the matrix for the casting of individual type characters and the duration of each casting operation are determined by a common automatic control which operates according, for example, to perforations formed in a travelling paper roll by the operation of a keyboard.

The invention has for an object to avoid handling or manipulation of the type pieces.

To this end and in accordance with the inven tion, at the termination of the casting of each set of type characters a member under the common automatic control cooperates with the type character last formed and shifts all the characters in the line channel clear thereof.

Also according to the invention, delivery means under the common automatic control cause each set of type characters to be delivered into the corresponding or appropriate compartment of a compositors tray.

For causing delivery of type characters into the corresponding or appropriate compartments of a compositors tray, a chute extending downwardly from where the type characters leave the line channel, or the lower part of such chute may be movable to bring the lower end of the chute into positions registering with the compartments, respectively, of a compositors tray located therebeloW.

Again, for causing delivery of type characters her and in spacing at their lower ends with a single row of compartments in a compositors tray may be movable under the common automatic control to register with several rows, one at a time, of the tray, the branches of the chute having shutters operating under the common automatic control to open one branch. only at a time.

The invention is illustrated by the accompanying diagrammatic drawings of which Figure 1 is a plan view of the arrangement and operation according to one form of the invention of a member for shifting type pieces clear of the line channel (part being schematic and drawn to a reduced scale), Figures 2 and 3 being sectional views on the line 22 of Figure l and 33 of Figure 2, respectively;

Figures 12 and 13 are diagrams showing in side elevation further forms of delivery means according to the invention; whilst Figures 14 and 15 show to a reduced scale an arrangement for use with a compositors tray having compartments of several sizes.

Referring first to Figures 1, 2 and 3, there is indicated at 2| the usual table of an existing machine having upstanding ribs 22 defining therebetween the line channel, indicated at 23, the usual line hook being indicated at 24 in the position occupied thereby at the end of its operative stroke. According to the invention, that normally displaceable part of one rib 22 which is indicated by broken lines (Figure 1) is removed or moved out of position and there is journalled in the table 2i a vertical spindle 25 having fast upon its upper end an arm 25 from which a pin 2'! extends through a slot 28 in a block 29 to be received in a bore in an auxiliary line hook 30 pivotally mounted on the blockat 3|. The auxiliary line hook 30, see Figure 2, is comprised by upperand lower members disposed on opposite sides of the block 29 to engage witha type character at both the upper and lower parts of the latter; part of the arcuate guide 32 being cut away at its under side to allow the lowerm'ember of said auxiliary line hook 35 to move between said arcuate guide 32 and the upper surface of the table 2!. To the upper surface of the table 2! there are affixed the arcuate guide 32 and a plate 33 which together provide a curved extension 35 of the line channel 23. Reciprocating motion is imparted to the spindle 25 through the medium of a crank 35 and a pneumatic cylinder and piston, indicated at 35, the supply of air to which is controlled by a valve 31 operated by an additional cam 38 on the usual camv disc 39 whereby motion is imparted to the, normal line hook 25. It will be seen that when the arm 25 moves in a clockwise direction the pin 2'! thereof will travel to one end of the slot 28 in the block 29, so rocking the auxiliary line hook 30 about its pivot 3! clear of the line channel extension 34 and will then carry with it the line hook and the block 25 to the end of the clockwise stroke. Similarly, during anticlockwise movement the lever 25 will first move to carry the pin 2'! thereof to the other end of the slot 28 in the block 29 so rocking the auxiliary line hook about its pivot 3! into position across the curved line channel extension 34 and will then move said block 21 and line hook 30 bodily therewith. To ensure such rocking of the lever 35 at thecommencement of the clockwise and anticlockwise strokes, the block 29 (see Figures 2 and 3) has one margin shaped, as indicated at 40, to co-operate under the influence of a leaf spring 4| with undercut walls of a recess 52 in the arcuate guide 32; frictional co-operation of the block 29 with said walls ensuring that the block 23 shall not move until the pin 21 has reachedone end or the other of the slot 28. At the outlet end of the curved line channel extension 34 the table 21 is formed with a delivery opening 43 through which type pieces, indicatedat 44, fall upon leaving said extension 34, a delivery chute extending downwardly from said opening 43, as indicated at 45. The curved guide 32 is formed throughout that part of its length opposite to the plate 33 with a continuous projection 45 for engagement in the usual grooves in the type pieces 53 to resist any tendency of the latter to tilt during their passage along the curved line channel extension 34. The timing of the strokes It will be understood that the mechanism just described is intended as a fitment to or modificaof the auxiliary line hook 353 is such that the auxiliary line hook 35 commences each operative or type delivering stroke as or immediately after the normal line hook 2d completes its operative stroke.

tion of an existing machine which as a rule, if not invariably, will have insufiicient space below the table 2! at the point where the type pieces 44 enter the curved line channel extension 34 to accommodate a delivery chute such as 45. In order that the auxiliary line hook 30, the arm 26, block 29 and the arcuate guides 32 and 33 shall not interfere with the normal delivery mechanism of the machine when the latter is used for composing, said parts may either together comprise a readily removable unit, or they may be so mounted individually upon the table 2| as to bereadily removable therefrom. Also, if desired,

means may be provided for closing the delivery opening 43 in the table 2|. I The outer curved wall of the curved extension 34 of the line channel 23 ,may be adjustably and/or resiliently mounted so that the width of the curved channel extension 34 may be varied to suit type characters of different sizes. For this purpose the outer curved wallmay itself be deformable, e. g. formed from thin springymaterial.

It will also be seen that in some cases it may be possible, instead of providing an additional line hook such as 35, so to modify the mechanism operating the normal line hook such as 24, that,

the operative stroke thereof may be increased so that it will remove all the type characters from the normal line channel.

In the delivery mechanism shown in Figures 4 to 11, a carriage for a compositors tray is moved, each time the matrix of the machine is moved, to bring a corresponding compartment of a tray on the carriage int'o register withithe place where type characters fall on leaving the line channel,

for instance, in the case of the arrangement de scribed with reference to Figures 1, 2 and 3, into register with the lower end of the chute 45.

Referring first to Figure 4, two sets of guide rails 5! and 52, respectively, disposed at rightangles to one another carry two travelling frames 53 and 54 and serve together to support and to impart the desired motion, to a carriage 55 for a compositors tray (notshown). Movement in steps is imparted pneumatically to the two frames 53 and 55, the frame 53 having associated'therewith two sets of cylinders and pistons 56 and the frame 54 having a single pair of cylinders and pistons 51. The frame 53 has a pair of racks 53 with which co-operate retractable plungers 59, and the frame 54 has a single rack 60 with which co-operates a single plunger 6|, said plungers 59 and GI serving positively to locate the frames 53 and 54 in the various positions occupied thereby during delivery of type characters. a The cylinders 55 and 5! are mounted upon a base plate 62 which also carries the two sets of rails 5| and 52,and in the case of the-frame 53 (see Figures and 6) each cylinder 56 has a piston rod 63 protruding therefrom which is connected with one arm 64 of a bell crank lever 64, 65 which latter arm is formed to engage the notches of the corresponding rack 58, said lever 34, 65 being fulcrumed at 66 upon a block 6'! slidable on guide rails 68 supported at their ends on the cylinders 56.

The pneumatic operation is such that the cylinders 55 at one side or the other only of the frame 53 function at a time to move said frame in one direction or the other through a distance corresponding with the distance between adjacent rows of compartments in a compositors tray in position on the carriage 55, the stroke of each slide block 61 being limited in one direction by the mounting of the guide rods 68 on the corresponding cylinder 59 and in the other direction by a fixed housing 69 for the plunger 59 carried on the guide rods 68. The slidable block 61 on which the bell crank lever M, 65 is mounted may be spring or frictionally loaded to ensure proper or full engagement of said lever 63, 65 with a notch of the rack 58 before the block 6! is shifted.

The plunger 59 extends downwardly from its housing 39 and when in the locking position is spaced at its lower end from the base plate 62 by a distance only slightly greater than the depth or length of the teeth on the rack 59, this downwardly extending part of the plunger 59 being in lost motion connection with corresponding ends of two levers III, II, I0, I! the arms it of which extend between flanges E2 on the plunger 59. The levers I9, H are fulcrumed about a common pivot l3 and the arms lI thereof extend over pneumatically operated plungers Hi (see Figure 6), the raising of either of which results in downward movement of the arm 19 of the corresponding lever 70, TI into co-operation with the lower flange E2 on the plunger 59 and therefore in re traction of the latter from the rack 59. Each lever 19, III has a pin it extending therefrom over an axially slidable valve member 19 the head TI of which normally co-operates with a seating E8 to shut off from a supply of compressed air (see Figure 9) connected with a port I9 from the cylinder 56 at the corresponding side of the plunger 59 which cylinder has an inlet 89 connected with the outlet SI of the valve. Each plunger 74 (as indicated by dotted lines in Figure 5) is movable in a cylinder 82 having an inlet 83 connected with the supply of air under pressure.

Admission of air to a cylinder 82 raises the corresponding plunger 14 and depresses the arm I of the corresponding lever I9, H, the pin 15 of which co-operates with the corresponding valve member 79 and depresses the latter to place the corresponding cylinder into communication via the inlet i9 with the above-mentioned air supply. The downwardly moving arm 19 also co-operates with the lower flange '12 on the plunger 59 and retracts the latter from the rack 58. As a result the corresponding bell crank lever 64 is rocked about its fulcrum 69 to bring the arm 65 thereof into co-operation with a notch of the rack 53 and then the slide block Bl moves from the position shown into contact with the plunger housing 69 carrying with it the rack 58 and frame 53 through a corresponding distance which is equal to the width of one cornpartment of the tray (not shown). In order to ensure that movement as described of one lever Ill, II shall retract the plunger 59 and yet open one only of the valves I9 the distance between the upper end of each valve member 15 when closed and the pin I5 of the corresponding lever 79, H when in its normal position as shown, is greater than the distance between the lower end of the plunger 59 and the base plate 62.

The mechanism for imparting movement in steps to the frame 5 is as above indicated the same as that for moving the frame 53 except that only two cylinders 5's and a single rack 69 and plunger SI are employed. In this case (see Figures '7 and 8), the two cylinders 5! are mounted on the base plate 62 with their piston rods 84 connected with a bell crank lever 85 fulcrumed at 86 upon a block 8! slidable, if desired, against frictional or spring resistance, on guide rods 88 between the mountings of said rods 89 on the cylinders 51 and a fixed housing 99 carried by the rods 88 for the plunger BI. Also the mechanism associated with the plunger SI is equivalent to but not precisely the same as the mechanism for operating the plunger 59, two levers 99 extending in opposite directions instead of alongside one. another as do the two levers I0, I I. The levers 99 are forked at their ends (see Figure 8) and each has a laterally extending pin 9| which instead of co-operating directly with a valve member co-operates with one end of a further lever 92 which acts upon a valve member 93 at its other end. This valve member controls the connection of the corresponding cylinder 5! with the source of compressed air in the same way as the valve member '56 controls the connection of the cylinders 56 with said source. The pneumatic plungers for actuating the levers 96 are indicated at as, the connection of the air supply thereto at 95, and the inlet and outlet for air past the valve member 93 at 96 and 91, respectively, and the inlet for air to the cylinders 57 at 9B.

The operation of the mechanism described is controlled by the normal or exist-ing automatic control of the machine in which a paper strip, indicated at 99 in Figure 9 of the drawings, is fed continuously over the open ends of a series of air pipes I99 to determine into which of these compressed air can enter from a common supply chest !9I. As is well known there is as a rule a considerable number of such pipes 599 but only five of these are utilized for the purposes of the invention, these five alone being shown in the drawing. Each of these five pipes is tapped or branched, as indicated at I92, so that air entering it actuates or controls part of the mechanism according to the invention as well as part of the machine normally actuated or controlled thereby.

It will be remembered that the supply of air to each of the cylinders 56 and 51 is controlled by a corresponding valve E6 or 93, these valves being in turn operated by pneumatic plungers I4 or 99. Each plunger M or 94 receives air under pressure by which it is operated to open the corresponding valve from the same source as the cylinders 55 and 57 under the control of the corresponding one of a number of valves in a chest I93, the two pneumatic plungers l4, actuation of which results in movement of the carriage 53 in the one direction, being controlled by the valve IM, and the other two plungers l4 being controlled by the valve I05, whilst of the two plungers 94, one is controlled by a valve I96 and the other by a valve I97 in said chest I03. A further valve H39 in the chest I93 serves to connect the inlet sides of the valves I94, 35,196 and I9? with the air supply, indicated at I99, and all of the valves IIl l, i95, I99 and I97 are operated by air reaching the chest WI according to apertures formed in the paper strip 99 passing over the open ends of the pipes I99.

The valve chest IE3 is shown more clearly in Figures and 11. Each valve I94, I95, I06, I01 and I98 is in the form of a plunger and as shown in Figure ll. in the case of the valve I94 comprises a head IMA having a stem I953 with which cooperates one end of a corresponding rocking lever HMC bearing at its other end upon a pneumatic plunger IMD raising of which latter by air via the corresponding pipe H39 and branch I02 opens the valve. Air outlet pipes from the valves I94, I95, I95 and IM are indicated in Figure 10 at IMX, IBEX, 506K, and IllIX and the inlet sides of these valves are connected with one another by a bore H9 in the chest I93 and via a pipe II with the'outlet side IEiSX of the valve I98, the

inlet I08Y of which is connected with the air supply I09.

It will be seen that when the carriage 55 is stationary, for example, during the casting operation, air from the supply I09 is shut off from the cylinders 55 and 57 by the valves 16 and 93, respectively, and from the inlets of the valves I04, I05, I06 and I07 by the valve I08. At the termination of a casting operation air from the chest IOI is allowed by an aperture in the paper strip 99 to open the valve 908 thus placing the valves I04, I 05, I 06 and it? into communication with the air supply I09, then, according as a compositors tray on the carriage 55 requires to be moved in one or both dimensions to bring into position for the reception of type the compartment of the tray appropriate to the characters next to be cast, the appropriate valve or valves of the group I04, I05, I06 and I0! is or are opened to efiect the necessary movement steps of one or both of the frames 53 and 54 and thus of the carriage 55.

Each of the pipes I00 which is branched for the purposes of the present invention will in general be one the passage of air through which alone will not bring about any operative function of the machine as apart from the present invention, e. g. in moving the matrix, and further that pipe I00 which is tapped for the control of the valve I 08 will be one the passage of air through which renders the machine incapable of casting. Not until air ceases to pass through this pipe will the next positioning of the matrix to determine which type character shall next be cast take place. Thus, it will be noted that the tapping of the pipes I00 apart from that leading to the valve I08 will in no way affect matrix positioning or other operations of the machine because opening of any one or more of the valves I04, I55, I05 and IIJI when the valve I08 is closed is ineffective.

All the members which are shifted pneumatically according to the invention are returned to their normal positions by springs which for the sake of clearness are not shown in the drawings.

Means, not shown, may be provided for enabling any or all of the valves I04, I05, I06, I01 and I08 to be operated at will manually.

The mechanism described with reference to Figures at to 11 is for imparting movement to a compositors tray beneath a fixed delivery outlet for type as indicated in the opening paragraphs of the specification. However, a compositors tray may in some cases remain stationary and an outlet for type may be moved instead, by mechanism similar to, but of lighter construction than, that described with reference to said figures. For example, as shown in Figure 12, a chute such as 45 of Figure 1 may have its lower end formed as indicated at IZI and terminating above a funnel-shaped type delivery member I22, the outlet I23 of which corresponds in cross-sectional area with individual compartments of a compositors tray indicated at I24, this funnel being carried by rollers I25 running in rails I26 extending in one dimension and on a carriage I27 mounted for movement on rails I23 extending in the other dimension. It will be noted that in such an arrangement the intake end of the delivery member I22 will be of the same shape and at least of the same size as the tray I24.

Again, as above indicated, a delivery chute such as 45 Figure 1 may feed the type to a branched delivery chute at I29 (Figure 13) which latter as a whole is pivoted about an axis I30. The outlet orifices I3I of the branched chute I29 are disposed in a straight line and correspond in number with the number of compartments in a row of a compositors tray, indicated at I32, each branch being controlled by a pivoted shutter I33 so that type entering the chute I29 can issue therefrom via one only at a time of the outlet orifices I3I to determine into which of the compartments of a row type characters shall be fed for any casting operation. The automatic control means in this case serves to bring about the operation of the shutter I33 and also to bring about movement of the chute I 29 as a whole about its pivot I30 to bring the outlets I3I into register with the different rows of compartments of the tray I32. It will be seen from a consideration of Figure 13 that the shutters I33 are so arranged that those in the lowermost row may be operated simultaneously as by a control rod I34 and that the intermediate pair of shutters I33 also may be operated by a single control rod I35, the single shutter I 33 at the top having a control rod I36.

In order to provide clearance for the usual flange or upstanding wall at one side of a compositors tray it is necessary that a chute from which type characters fall into the tray should terminate some distance thereabove. In order, so to speak, to fill in the gap between the top of the tray and the lower end of the chute there is provided a device resembling a bottomless tray which is placed in position above the tray to constitute upward extensions of all the walls thereof, thus eifectively preventing any jerking rments of difierent sizes some of the walls of the device will be extended downwardly to divide the larger compartments of the tray proper temporarily into separate compartments, thus eiTectively preventing any possible jerking of piled up characters from one compartment into another, and also ensuring even or uniform filling of the larger compartments. This is illustrated by Figures 14 and 15 of the drawings, of which Figure 14 shows a tray in plan and Figure 15 in sectional view on the line i5-I5 of Fig ure 14 with the device just mentioned in position thereon. As will be seen the tray has large and small compartments I5I, I52, and compartments I53 of intermediate size. In Figure 15 the usual upstanding flange at one side of the tray is indicated at I54 and the bottomless tray device at 55. It will be seen that this device I55 extends over the whole of the compositors tray and is flush at its upper surface. Some of the partitions or compartment walls I56 constitute simply upward extensions of the compartment walls I5! of the tray, whilst other compartment walls I58 of the device extend downwardly into the large compartments 55! of the tray to divide them temporarily into compartments of smaller size.

Although in all the cases described use is made of the pneumatic type of automatic control common in machines of the kind to which the invention relates, it will be apparent that ,other forms of control may be employed. For example, the various operations or movements of the mechanism according to the invention may be brought about automatically as a result of electric circuits beingbroken or completed instead of by the open ends of air pipes being covered or uncovered by a travelling paper strip which latter in such case may carry Contact pieces or strips for co-operation with fixed contacts instead of being formed with apertures.
