KEYBOARD FOR COMPOSING-MACHINES.

Patented aug. ii, rara. 817,185.

To all 't0/mm 'it may concern Be it known that I, CHARLES E. BENHAM,

a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Keyboards for Comprising-Machines, of which the following is a specification. v

The present invention relates to key boards of so-called composing machines and in particular to key boards of machines o t the Lanston monotype system although it 1s not necessarily limited thereto.4 I shall, however, describe my invention with reference to such machines because it is particularly applicable thereto..

The ordinary key board in its operation requires that the operator shall depress and release a key each time its corresponding character is to be reproduced. In my Patent No. 1,099,734, issued June 9, 1914, I have described and claimed an improved key board arrangement whereby any desired character can be reproduced indefinitely so long as the key is held in its depressed position by the operator. When the key is released the automatic reproduction of the character' ceases and the operator proceeds in the usual manner. Suchen arrangement on account of its high speed of operation requires close attention and considerable skill on the part of thev operator to release the repeating key at the proper time, especially for tabular work Where the items are to be printed in vertical columns with considerable space between them.

The present invention is an improvement over the apparatus disclosed in said patent.

Briefly the principal feature of my invention resides in the addition of an arrangement whereby the action of the repeating key is automatically interrupted at the proper time whether it be at the end of the line or at some intermediate point. Two embodiments of thisvidea are illustrated. In one embodiment the operator holds the key depressed until a predetermined number of characters or punching operations have been made when a device controlled by the movement of some part of the mechanism, as the em rack for example, stops further repetition, the operator then releases the repeating key and proceeds in the normal manner. This action may take place one or more times for each line of the final printed page. In the other embodiment the operator depresses the repeating key which is imy med1atelylocked in that position by suitable means and remains so until the device controlled by the em rack or equivalentdevice releases it. From the view point of the op- 'bodiments resides in the fact, that in one case he or she must depress and hold the 'rel peating key until the necessary punching operations have been made when the machine stops, while in the other case it is only f necessary to depress the key and remove the ringer, after which the operations are re# .peated without his or her assistance, until the proper number of operations have been l made when the machine stops and the kev is returned toits normal position.- u

Uther novel features of my invention will ,be pointed out hereinafter.l V f In the accompanying drawings which are gillustrative of board fitted with my automatic stop; Figs. 2, 3 and 4 are detail views of the actuating and stopping mecha- Inism; Fig. 5 is a plan view of a device to fasten the flexible cord of repeater key Amechanism to the roc -shaft rods; Fig. 6 is ,a sectional view of the valve controlling the lribbon feeding mechanism; Fig. 7 is a detail View in front elevation of the em rack and stop mechanism; Fig. 8 is a plan view of the key banks; Fig. 9 is a sectional `view of the :em rack and stop bar; Fig. 10 is a detail plan Vviewof the means for temporarily locking the repeater key in its depressed position, and Fig. 11 is a perspective view of the stop bar arranged to coperate with the locking means of Fig. 10.

In'order that my invention may be understood and its relation to previously existing constructions appreciated, it is necessary to briey describe the latter; 11 indicates one of the ordinary keys which, when 4depressed by the operator, moves a bar having projections on the under side which in turn moves' the rods 12 mounted on the roc-k shafts 13. Each of these rods when pushed opens a valve 14 to admit compressed air to the cylinder of the motor 15. The piston in the Cylinder moves upwardly carrying with it the lever 16, bar 17 and punch 18, the

latter making holes in the paper ribbon 19.

y'.llie punches generally operate in pairs my invention,y Figure 1 is a perspective view of apart of a Lanston key repeating key and erator, the difference between the two emret lia

through the action of the rods, and the air pressure closes the valves when the key is released. In some cases, as for example with the quad key, it is common practice to omit the punch from one or more of the bars 17, because certain characteristics of the casting machine in which the ribbon is subsequently used, and in particular as regards the means render it unnecessary to perforate the paper for this character. Each bar and lever 1G, however, move up and down for each operation of its associated key and the ribbon 19 is advanced step-by-step between operations as in other cases, and hence the operation, except for the punch perforating the ribbon, is the same in all cases. The two motors and punch bars shown are typical illustrations of these devices of which a large number is provided for each machine.

To withdraw the punches and return them to their depressed positions and also to control the `action of the ribbon feeding means, mechanism includingr a tension arm 20 is provided that is actuated by a fluid motor 21 comprising a piston and cylinder. This motor always tends to hold the punches and rods depressed but is overpowered by the motors 15 when the latter are active. Connected to the tension arm by a link is a lever 22 that assists in the opera-tion of the so-called unit-rack slide.

23 indicates a leverthat is connected to the usual stop mechanism for the unit-rack slide.

Thel paper ribbon is fed between two perforated die plates 24 by toothed wheels 25. 'The shaft for these wheels is provided with a ratchet wheel 26, and the latter is advanced step-by-step by the pawl 27. The pawl is actuated by a rod 28 whose lower end is connected to the vibrating lever 29, the latter being tilted first one way and then the other by the pistons 30 and 31. Vhen the machine is at rest the left hand end of the lever is elevated and moves down and up for each punch stroke. The pistons are controlled by the two-way slide valve 32 which is actuated by an arm 33 having a cam slot 34, said arm being actuated by the spindle of the tension arm 20. In the Slot is a roller mounted on the lever 35,l the latter movingr the valve 32 to admit air under one piston and at the same time exhaust it from the other as shown in Fig. 6. The mechanism so far described is old.

As in my said patent I utilize the mechay nism which withdraws the punches and retracts the bars and specifically the vibrating lever 29 of the paper feeding mechanism to perform the work of actuating the valves 14 of motors 15 when the repeater key is depressed, but I do it in a different manner and attain new and advantageous results. u

40 indicates a liexible connector which can for movin'T the matrix case best be made of metal cord or chain. It is connected at on-e end to a pair of the valvev rods 12 as in my prior patent butv in a diiierent manner. The rods 12 are connected to the rock-shafts by vertical pins 41. Between a pair of pins I slip a strip 42, Fig. 5, of rather thin metal having notched ends partially embracingr the pins. These strips have holes 43 to receive the ends of the connectors. One end of each connector is first attached to the strip, then the assembler flexes said strip with his fingers and slips it between the pins. When released the notched ends ofthe strip hold the same in place. This greatly facilitates the securing of the connectors and rods and also materially reduces the labor of adjusting the connector to obtain the exact length desired. In connection with this, as well as other devices toV be described later, it must be Vremembered that one of the very great features of my invention is that the apparatus can be applied to existing machines without rebuilding them. The connectorV passes around pulley 44 and up over the pulley 45, said pulleys being mounted on the yframe of the machine. In my patent aforesaid the Aother end of the flexible connector 1s connected directly to the vibrating lever 29.

This former arrangement is entirely satisfactory in so far as the work performed by it is concerned, but it is rather objectionable in some cases from the view-point of wear and tear to have the connector continually subjected to motion. I avoid this by the additionvof a lever 46 which is normally stationary and whose fulcrum is, or may be, the same as that of the lever 29. By using the same fulcrum 47, Figs. 3 and 4, for both levers 29 and 46, extra parts and unnecessary work are avoided. The lever 46 may either be flexible in a. plane perpendicular to its length or it can be loosely mounted on its fulcrum to permit its free end to be moved away from the lever 29 to disengage the parts, as will appear later. Carried 'by the auxiliary lever 46 is a pin 48 that Vpro- Y jects into the vertical plane of vibration of the lever 29, but normally stands'j ust below the region of said vibration and is, therefore, not affected. A spring 49 tends to hold the auxiliary lever down thereby keeping the flexible connector 40 sufficientlyv taut to prevent idle movement as well as quad out a lineV 'inmates ing parts. lVhen pressure is first applied to the repeating key, the auxiliary lever is held down because the right hand end ofthe main lever 29 rests on its pin 48. The upward movement of the punches turns the tension arm 20 on its axis together with the arm 83, which shifts the valve 32 to the left, the latter admitting air under piston 3l by pipe 3l and permitting it to escape from under piston`30 by pipe 30a. Then the right hand endof lever 29 rises it releases the pin 48 thereby releasing the tension on the connector 40 and valves 14 cut ofl the supply and release the air from under pistons 15 and the latter return to normal position. This movement is accompanied by a shifting of the-valve 32 wit-h the result that the left hand end of the main lever 29 rises and its right hand strikes the pin 48 which restores the tension to the connector 40 and the action is repeated until some further act stops it. Owing to the fact that one or more of the motors act in response to a movement of the repeating key, the feeding mechanism will advance the ribbon 19 between each two similar movements, and hence it makes no difference if a punch has been omitted from a unch bar, providing, of course, as heretofbre explained in connection with the matrix case of the casting machine, a punch is unnecessary to the successful operation. V'Vhether a punch is used or not the record is made. In the one case the ribbon is perforated and in the other case not.

I will next describe an arrangement whereby the automatic action of the repeating key can be arrested at any predetermined )oint or points, particularly with the idea o facilitating the work where parallel columns in the printed age are required.

The machine is provi( ed with an ein rack extending across the front and carrying the usual pointer 5G traveling over the fixed scale plate 57. Just below the rack I mount a bar 58 on pivots 59, the latter can be made of screws and threaded into the frame of the machine, there being ample space for the purpose. This bar is held in the raised positicn by the spring 58 andhas one or more adjustable stops (30, each having a top with a right and a left hand beveled face. Carried b v the ein rack is a finger 6l which, when it strikes a stop, depresses the bar and raises the arm 62 forming a side extension. This arm when elevated, assuming the repeating key to be held depressed by the operator, moves the right hand end of the auxiliary lever 46 sidewise by an amount suicient to pull the pin 48 out of the region of vibration of the main lever 29, the final I result being to release the tension on the connector 40 as completely7 asl though the repeating key had been released and the machine stops. The operator is then free to Work the machine in the normal manner or the stops.

The next key influence of the main lever 29 the are free to move upwardly at the rear en Subsequently they are returned to normal position by spring 49. The rear end of the arm 62 is made to form a beveled faced cam so as to assist in moving the rear end of the lever and its pin 48 out of the path of lever 29. A screw 63 enables the necessary fine adjustment to be made. I have described the adjusting screw as being mounted on the auxiliary lever, but it can be mounted on the arm 62.

l Each stop on the front bar 58 is adjustable sidewise and also vertically and is held in place by a screw (S4. ln order to insure the proper setting of these stops and hence the accurate stopping of the machine, they may be provided with pointers 66 that roject in front of the scale plate 57 for the purpose ofcoinparison. By beveling the upper faces of the stops as shown, the em rack .and finger 61 can be moved in either direction by the normal mechanism. In other words, aside from serving as a stopping means or discoiinector for the repeater key, the bar and its stop have no effect. During the usual key-by-key oper-ation the finger 6l will ride over the stops first depressing tlie bar 58 andk then releasing it, the auxiliary lever arrangement permitting this to take place.

In Fig. 7 is shown in elevation the relation of certain parts when mounted in place on the machine. 55 indicates the ein rack which is mounted to slide in the slotted member (37, Fig. 9, said rack being driven by the pinion 68 on the shaft 69 of the unit wheel 70. 55 indicates a roller for holding the em rack down so that it will not be forced out of place when the finger 6l strikes a stop (50 on the bar 58. The pawl 7l serves to hold the wheel until certain machine operations have been completed. 72 indicates the so-called driving cylinder and i rotates the shaft 69 through the usual means that need not be described. 73 is the stop for the em rack 55. Below the rack is the pivotally supported releasing bar 58 for the repeating key 50. Above the bar is the scale plate 57 which is common to the ein rack pointer 56 and to the pointers 6G on As constructed the em rack pointer 56 and the finger (il are made of one piece, said parts extending through small holes in the em rack and being united on .the back by (36, Fig. 9, after the fashion of a hair pin. This has the advantage that the pointer 5G prevents the finger Gl from turning when it strikes a stop. The arrange- 'ment is simple .in the extreme and also avoids additional clamping means which would cost money to -make and would be more or less in the way.

In Fig. 8 is shown an arrangement Whereby tworepeating keys 50 and 74, representing for examplea quad and a. leader, are located in the right and left hand key banks. Key 50 acts through the push rod 5l on lever 52, and key 74 through push rod 75 on the bell crank lever 76, the `latter being connected by a link 77 to the lever 7 8. The levers are connected'by flexible connectors 53 and 79 to the main connector 40, Fig. 1. The levers are held in tension by the springs 80. Each lever has a stop 78a to limit its movement. It will thus beseen. that either repeating key may be used to control the auxiliary lever 46, Fig. 1. It is to be understood, of course, that where the keys represent different characters, as they nearly al- Ways. would, two connectors 40 are provided Which extend to differ-ent pairs of rods 12.

As described thus far it is necessary for the operator to hold the repeating key down so long as it is desired to repeat the same character. That is to say, until the finger 61 automatically causes the release of auxilia'ry lever 46.l I will now describe a means whereby the act of depressing a lrepeating key in addition to starting the mechanism into automatic action Vwill lock said key in it-s depressed position until released by the action of the iinger 61, stop 60 and bar 58. This is a feature ofA Treat importance when combined' with a sultable stopping means for it saves Work andv mental strain on the operator. It also gives the operator time in which to perform other Work or move his hand preparatory to striking a normal key. As an illustration of this feature of my invention I have shown in Figs. 10 and l1 the bar 58 provided with a suitably guided arm 85 which extends in front of the levers 52 andl 78. This arm is provided with tvvo notches 86 and 87 the former' occupying a position in front of a projection 88, Fig. 10, on the lever 52 and the latter a position in front of projection 89v on lever 7 8. The portions of the arm adjacent the notches have beveled faces 90 and 91 over which`- the projections 88 and 89 ride. These levers are connected b flexibleconnectors 53 and 79 to the auxi iary lever 46, or they may be connected to the main vibrating lever 29 as described .in my previous patent aforesaid. The levers 52 and 78 overlap to reduce the overall total length. They are held in the position shown by extension springs 98 of suitable strength, which are secured at one -end to fixed supports on the machine frame and at the other ends to thelevers. The

lever 78 has a projection 78a that extends below it and forms a stop. The other lever is also provided with a similar stop.

When the operator depresses key 50 the push rod 5l turns the lever 52 against the tension of its spring-until the projection 88 drops into the notch 86. This action sufiices to put the connector 40 under the necessary tension to cause the automatic repetition of the unch rods controlled by the key as alrea y described. In addition the vWall of the notch holds the rojection 88 and locks the lever 52 so that t e operator can release the key without stopping the automatic action. The punches Will continueV to 'make holes in the paper ribbon 19, Fig. 1, or the rods to move up and down until the finger 61 `on the em rack 55 strikes a stop'GO and depressing the bar 58 moves the arm 85 and its notches a distance sufficient to release the projection 88 and the machine stops. The action is the same for the other repeating key 74 except that the projection 89 enters the notch 87 and is held unt-il released by a 'downward movement of the bar 58. When the tension on the connector is removedby releasing either the lever 52 or 78 the spring "58, Fig. 2, returns the auxiliary lever to its normal position Where the movements of the main lever 29 do not affect it.

The flexible connectors can be made of any suitable material but after considerable experiment-ing I have found the small chains used on pull-sockets for incandescent lamps .to be the best, as they are not only very fiexible but are exceedingly strong for their size and do not stretch.

The combination `of my repeating key mechanism with stop mechanism actuated by some movable part of the machine, asthe em rack for example, is of importance ioo for various kinds of Work but has its greaty est. value for tabular Work Where one, two or more columns are to appear on the printed page, the remainder being quadded out or filled With dots, dashes, or other characters. It saves the operator both mentally and physically and insures absolute alinement of the various items in .the columns as I have demonstrated 1n practical Work. I prefer to use the em rack as a device to actuate the stop mechanism because it. is in plain vie'W and enables my improvement to be applied to existing machines without rebuilding, thereby increasing its field of usefulness, but I do notjwish to be understood as limiting myself thereto. Furthermore, the arrangement permits me to use one scale plate for the em rack pointer and the adjustable stops.

The locking of the repeating key in its depressed position is desirable in all cases because it relieves the operator mentally and physically. It has its greatest utility of course for tabular Work, or Work requiring continued use of the leader, quad or dash character. By combining the stopping and locking mechanism in one structure, as in groesse Figs. 10 and 1l, I simplify the mechanism as a whole, reduce the number of parts and am able to locate it ivhcre it is accessible.

I have described my improved arrangement as depending for its action on the auxiliary lever i6, and in some instances on the main leverv 29, because either of these arrangements can be applied with the minimum amount of labor and expense. It is evident, however` that luy invention is not necessarily limited thereto since other vilirating parts of the usual operating mechanism can be employed. This is particularly true where the improvement is being incorporated in a new design where one need not be bound by the limitations imposed by existing structures and where success or failure is not so completely determined by simplicity and the ease with which the improvement can be added. It is also evident that while I have described the con.` nector between the valve means or controller for the motor and the mechanism movin in synchronism with the feeding of the rib on f as beinfr flexible. m invention is not to be construed as being so limited unless so stated in the claims.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and
