Application filed November 29, 1922. Serial No. 604,069.

To aZZ whom it may concern.-

Be it known that I, MAUnrrZ C. INnAHL, a citizen of the United States, and a resi dent of Philadelphia, county of Philadelphia, State of Pennsylvania, have iiiyentcd' certain new and useful Improvements in Typographic Casting and Composing Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accoi'npanying drawings, forming part of this specification, and to the characters of reference marked thereon. I r

This invention relates to typographic casting and composing machines adapted to operate in accordance with signals such as those in the form of perforations in a controller strip. A machine of the kind referred to is eXemplitied in the commercial product of Lanston Monotype Machine Company. and its basic principles are wellknoiyn and are shown, for example, in United States Letters Patent No. 625,998 dated May 30, 1899. The record strip itself may be produced in any. suitable manner but is preferably the product of a keyboard ma: chine such as that, for example, illustrated in United States Letters Patent No. 944,405 dated December 28, 1909, or an improved form of such patented machine.

In the present commercial form of these machines the keyboard produces per-tors tions of such nature as to act directly in the casting machine to thr'oiv up gage pins or It has been proposed. for examine, in United States patent application No. 582,238, filed August 16, 1922, to construct a keyboard mechanism bv which controller strip signals of an indirect nature may be produced, namely, combinationor' additive signals in which each perforation does not represent a definitegage or other mechanism to deter mine matrix case or wedge location, but in dicat'es a definite value to which the values of the other perforations in the signal are to be added in order to arrive at the meaning and effectof the signal as a whole.

fin object of the present invention is to produce a machine for operation in accordance with, and under the control of, such combination signals. Another object is to provide a typographic casting and composing machine. such as that basically shown 1n Patent 625,998, above mentionethavith an interpreting mechanism whereby the usual matrix and Wedge locatingmechanism may be actuated in accordance with such combination signals. Another object is to construct a machine having a plurality of motors or mechanisms to be actuated, such as pneumatically operated locational gages, whereby such machine will operate under control of a record strip having signal indi cations the greatest possible number of Whicl'i is less than the number of said motors or mechanisms. A more specific objectis to produce a machine of the kind referred to in which a strip having a relatively small signal indication capacity controls interpreting mechanism provided With bars havingselectively positioned openings or the like, which bars by combination as controlled by the signal components, open a single through Way or passage for each com bination to actuate a single motor such as the gage pins 150 hereinafter refe-ried to; thus each combinationthough possibly made up of a plurality of signal components or values, in the form, preferably, of per-fora tions, produces by combining: these Values, a sing-1e effect; but the total number of signal perforations of which the strip is capamet-nay be less in number than the motors, as 150, to be actuated.

Further objects and advantages will hereinafter be particularly pointed out or will otherwise appear in connection with the fol lowing description of the embodiment of the invention illustrated in the accompanying' drawin s in which 1- Fig. 1 is a side elevation of the air or paper tower of a machine similar to that of Patent 625,998 previously referred to and embodying; the present invention.

The paper tower shown in the drawings will be recognized as a part of the patented machine above referred to, it being deemed unnecessary to show other portions of the machine because it is well-known to those skilled in the art. The w-ellknown mechanical elements of the machine shown may be referred to briefly for identificationpurposes, for example, the top stand 1 of the machine, the paper tower base 2, the housing 3, the paper tower lever at, the paper feed pawl ring 5, the air bar clamping lever 6, the locking lever 7, the winding spool. 8. the paper feed operating rod 9, the bell crank lever 10 for operating the rod 9, the air bar lever 11, the paper feed ratchet 12, the cross girt or tracker bar 13, the pin wheels 14 pro vided with pins for engaging with marginal perforations in the controller strip for feeding the same, the air bar 15, the air valve 15; and in Fig. 6 are shown diagrammatically the pin blocks B and C and their pin jaws and pneumatically operated gage pins or motors 150, as well as motors operated by air under pressure from the cross girt 13 to govern other gaging devices of the machine when it is to operate in accordance with justification space signals and justification signals, these motors being marked S for the justification space signal, J75 for the .0075 justification signal, and J5 for the I .0005 justification signal, these signals being well understood in the art.

In accordance with the present invention, the cross girt 13 is made narrower to accommodate a narrow paper, and contains only eleven ports instead of the usual thirty-one. The piping is also altered and the paper tower is provided with an interpreting mechanism 16 secured at the back of the paper tower. This mechanism may be readily divided into two groups, one pertaining to the B pin block of the machine, and the other to the C pin block thereof. Each group embodies four permutating bars 17, each bar being operated, through the intermediary of its bell crank lever 18 pivot-ed to the'paper tower housing, by its motor 19, each motor being connected with its appropriate port in the cross girt by one of the pipes 20. Each bar 17 is normally retained in a retracted position by a spring 21 connecting one end of the bell crank lever 18 with the piston block 22 in bores in which the motor pistons 19 are located. The motor pistons 19 are staggered as illustrated, (Fig. 5), and the bell cranks 18 have their horizontal arms laterally extended to reach directly under the pistons 19. Each bell crank lever 18 is provided with two lugs one of which in each case engages with its corresponding piston 19, and the other of which engages with the bottom of the piston block 22 to act as a stop against the pull of spring 21. The bars 17 are horizontally slidable in a slotted frame member 2a which rests upon the casing 25 secured to the base 2. One group consisting of four bars is in the front of and the other four-bar group behind a series of air valves 25 located in bores in the air block 26, which block is covered by a cover plate 27, the block and cover being secured to the casing 25 by screws 28. The valves 25may be regard-ed as consisting of two groups, each group of fourteen valves each, one group pertaining to the B pin block and the other grou to the C pin block. The casing 25 is provic ed with screws 29, (Fig. 4), by which the casing is secured to the air tower base 2, and has screwed to its upper portion a slotted plate or frame for the accommodation of valve operating members or fingers 31. These members have horizontal upper portions lying in the slots of the plate 30, and vertical descending portions for engagement with operating bar 32. The members 31 may also be considered as of two groups, fourteen in each group, each member being in contact along its rear edge with the corresponding member of the other group and their horizontal portions extending in opposite directions. It will be understood that the operation in an upward direction of any member 31 in the B group will open a corresponding valve 25 in said group, and that the operation of any member of the C group will likewise open a corresponding valve 25 of the C group, the valve stems being in line with the members 31 for this purpose.

The operating bar 32 is located in a cavity, one half of which is formed in the B group of members 31, and the other half in the C group. This bar is journaled at its ends to the forked ends of the lever 33 pivoted at 34 to the casing 25 and having its outer end provided with a cam engaging surface 35. The operating rod 36 is pivotally connected at its lower end 37 to the paper feed bell crank lever 10 previously referred to, its upper end being provided with a cam face 36 slidably held by a bracket 36', secured to the casing 25 so that said cam face may engage with the surface of the lever 33. On the upward movement of lever 10 the cam 36 will act, as is obvious,

30 of the rod 36 is moved downwardly sufficient to allow lever 33 to swing and the operating bar 32 to move upwardly due to the action of the plungers 37, one for each member 31, as shown in Fig. 7. It will be understood that the construction is such that the air in traversing signal perforations will operate motors 19 and permutating bars 17 before the members 31 are allowed to move upwardly. Such upward movement will result in one of the members 31, for each group, passing through a through way provided by the combination of permutating bars, in which case these members will open corresponding valves 25 and thus cause corresponding locational gages to be operated. These gages may be referred to as motors to be actuated and are shown in the form of air pins 150 in the pin blocks 18 and C to be operated. Likewise the cams 35 and '36 are so positioned and formed as to cause the retraction of the members 31 during the upward stroke of the lever 10 before a new signal has been presented which may result in the shifting into a new combination of the permutating bars 17.

The plungers 37 which act to operate the members 31 are provided for this purpose with stems 38 surrounded by coiled springs 39 (Fig. l). These springs serve to move the plungers upwardly and consequently the corresponding members 31, there being a cavity 39 formed in the frame member '30 and shown in dotted lines in Fig. 4. to perm-it this upward movement of the plunger-s 37. It will be noted by an inspection of Fig. 7, that these plungers are staggered so as to take up as little room as possible.

Whether the two groups of members 31 are permitted to operate in an upward direction to open their corresponding valves, depends upon the permutating bars 17. It will be noted particularly in the diagrammatic representation shown in Fig. 6, that these various permutating bars are provided with slots or ways in their lower edges, these slots being selectively arranged in the individual bars so that the operation or non operation of any one or more of the bars will present aligned slots for permitting "the upward movement of one of the valve operating members 31. In any combination of positions for the various permutating bars in each group, there will be only one throughway or passage provided by the alignment of slots in the various bars, this through-way permitting the thus selected operating member 31 to move through its operating distance in an upward direction and in so doing extend into the slots 50 and operate its corresponding valve 25.

In Fig. 0 the operation of the device, the construction of which has already been described, is diagrammatically shown. and it will be observed that the cross girt 13 is provided with eleven ports, the values or mean-- ing of which are lndicated from left to right as follows:1, 2, 8, 4-, S, .0075, S, 1, 4: and .0005. When a controller strip is threaded into the feeding apparatus of the paper tower, and the air bar 15 is clamped against it, air will pass from the bar 15 through whatever perforations are in the paper, it being noted particularly that the maximum number of perforations or of sig nal components is eleven instead of-the usual thirty-one. If a perforation opposite the port S is opened, air will pass, as shown in Fig. 6, to the justification space motor S, and will operate this motor and cause the casting machine to perform so far as this particular perforation is concerned, in its usual manner; likewise if port .007 5 or port .0005 is opened, air under pressure willcauso the justification motors J or J5 respectively, to operate in the usual manner. The remaining ports may be divided into :two groups having values 1, 2, 4; and 8-; the left hand group leads to four motors 10 which control the group of permutating bars 17 for controlling the pins of the C block, while the right hand group of perforations controls similar motors and bars for the 1% block. The values of the various permutating bars of each group are numbered 1, 2, 4 and 8, and these bars correspond exactly to the values of the ports as already given. In the retracted position of the bars, as shown, there is no combination of slots which will allow a valve. operating member 31 to move in such a way as to operate a valve 25,. Consequently, this being a condition of no signal perforation whatever in the controller paper, the jaws of the B pin block and those of the C pin block will op crate in the usual manner to come together at the particular end 'pin numbered B 15 and C 15 respectively, which pin is not connected to any air pipe, but is permanently attached to the pin block in raised position The jaw nearest the permanent pin is con structedso that 'it will slide over this or any pneumatically operated pin. without contact, the jaws being spring controlled so that the jaw farthest from the permanent pin, first moves to contact with the nearest operated pin or with the permanent pin if no other pin is operated, and thereafter the j aw nearest the permanent pin moves until it comes against the other, pin-located jaw. In the position of the jaws, as determined by the permanent pin, the matrix case will be brought to a position for casting a quad in accordance with the usual practice.

If, however, any perforation occurs as to the two groups of perforations having values, the correspondingly valued motors 1S). bell crank levers 18 .and permutating bars 17 will be operated to produce a combination of slots for permitting the operation of a member 31 and its corresponding valve 25. When a valve 25 is operated by moving upwardly, air under constant pressure admitted above the valves through the pipe 40, (Fig. 4:), enters the chamber 11 and passing the valve seat will flow through the outlet channel 42 from this valve and through the pipe of the group of pipes or conduits 43 connected thereto. The farther end of this pipe is connected with a pin in one of the pin blocks which corresponds with the selected valve. When an operated valve has again become seated air from the pipe 13 will exhaust around the reduced portion of the. valve stem and through the passage' l: for that valve, there being such a passage for each valve provided in the valve block 26.

It will'be unnecessary to explain all of the possible combinations that may be obtained, although it may he pointed out that with four perforations in each group it is possible to operate any one of fourteen valves 25, and therefore, any one of the fourteen air pins in the pin blocks B and G. Let us however take one example for. explanatory purposes suppose air is allowed to pass through the ports 4 of the left hand group and 8 of the right hand group; the air passing through port 4 will operate a motor 19 and its cor-.

responding permutating bar 17 of the C group, this bar being marked with the value 4 corresponding with the value of the port (F ig. 6.) This bar in operating will move until its stop 17 comes against the casing 25 in which case the operation of'this bar and the non-operation of the other bars will produce a combination of slots in which a through-way is opened to the fourth menu ber 31 from the left in the C group, thus the fourth valve 25 will be operated'and the fourth pin of the C block, Similarly, air entering the perforation in the right hand group, the value of which is 8, will operate the bar in the B group which has the value of 8, and this will cause a through-way to be formed by the combination of slots, for the eighth operating member 31 from the left and correspondingly the eighth valve and the eighth pin in the pin block B. It will be seen that the pin corresponding in value to the port value indicated, is operated when that particular port is opened. When, however, more than one port is opened, as let us say, ports 8 and 1 in one group, the permutating bars, the values of which are 8 and 1, will be operated, in which case, as will be clearly seen by an inspection of Fig. 6, the ninth valve will be operated and the ninth air pin; thus each variety of combination could be explained and it could be shown as a result that the particular pin operated is that pin which corresponds to the sum of the values of the perforations presented. With the perforations in each group having a value of 1: 2 4: 8:, it will therefore be seen that fifteen air pins for matrix case location can be operated from four perforations, since 1 plus 2 plus 4 plus 8 equals fifteen: it may be noted, however, that in the particular embodiment illustrated, only fourteen pins are operated inasmuch as this number is all that is necessary in this particular machine.

It will be observed in Fig. 6 that the permutating bars are placed one above the other instead of in the same horizontal plane. This is a schematic illustration, not to show the actual construction, but to make plain the relation of the slots in the members, and, consequently, the operation of the permutating mechanism. 1

In Fig. 8 I have shown a modified construction in which the permutating bars 17 are shown with selectively arranged apertures 50 instead of the slots or notches 50 as previously described. These bars are operated in the same way as the notched bars. and in their combinations of position, the apertures being in the same relation as the slots, a throughway for air underpressure entering through pipe 51 into air chamber 52 is produced whereby this air traverses a selected pipe of the group 43 and operates a corresponding air pin 150. With this construction, the apertures themselves, when placed in alignment, form directly a pneumatic connection with the air pin, and the series of valves 25 and their operating 1nembers 31 are not necessary. A group of four valves, as shown in Fig. 8, will thus operate fifteen air pins similarly to one of the groups of permutating bars already described.
