16 Claims.

This invention relates to combined typewritin and computing machines, as, for example, an Underwood, in which numbers typed upon a work-sheet are also computed. The invention relates more particularly to automatic printing devices and provides novel features of type-train actuation and the automatic control thereof, which are an improvement over the invention shown in the pending application of Leo Starck, Serial No. 579,191, filed December 5, 1931 (now Patent No. 1,932,646, dated October 31, 1933).

The present invention is herein illustrated as embodied in a' machine usable for making out bills in which the different items are entered line by line and dated at the beginning of each line. For dating each item according to its entry-date, there may be used a special type-device as shown, for example, in the patent to Henry Resch, No. 1,512,310, of October 21, 192 i. The usual typetraln to which saidspecial type-device may be attached is brought into action automatically for dating a new item or line upon a bill, said automatic action being initiated upon typing of the last figure or letter in the preceding line or item of the bill. As shown in said pending application of Starck, and in the patent to De Haven & Schaaf, No. 1,432,678, the carriage is causedto be automatically returned after printing said last number or figure, the return being effected by an electric motor. 1 The carriage is automatically arrested at the end of its return movement, and the platen is automatically line-spaced preparatory to beginning the typing of a fresh line.

When the carriage thus reaches the beginning of a line, the next step is to cause the date to be printed. The third step is to then cause the carriage to jump or tabulate to the point of beginning the entry for the typing of the next item.

An object of the present invention is to provide for normal action of the date-printing typebar train, and is attained by novel means operative to impart an impulse to such train so as to have the same effect as finger-operation thereof. Accordingly the date-printing train receives a momentary impulse suflicient to cause normal printing impact of the type-bar, the novel means providing that said impulse is momentary in order to allow a normal rebound of said type-bar to its usual restored position. The letter-feeding or space-skipping operation of the carriage may thus ensue normally and need not be delayed for the return of the type-bar train, as has heretofore been the case when such return depended on comnism is started at a moment coincident with the settling of the carriage into drop-back position. It will be understood that said drop-back position is the position attained by the carriage after it strikes the usual return stop. By thus timing the operation of the date-printing train, any chance of printing the date out of place on the work-sheet is avoided.

Other features and advantages will hereinafter appear.

Keys 10, when depressed, swing type-bars 11 against a work-sheet on a platen 12 to print The numbers are printed by keys 17, and are indexed or set up on a mechanism, outlined at 18, and subsequently run into a totalizer 19, Figure 1. Pendants 20 rock shafts 21 to actuate a linkage 22 to depress index-pins 23. The index-pins 23 on bars 24 are set seriatim as the typewriter-carriage 13 is fed. Carriage-tappet 25 actuates jack 26, link 27 and transposition device 28 to move the denominational bar 24 forwardly, as more fully described in Patent No. 1,280,065, to Minton.

A general operator 29, driven by motor 30, drives bars 24 and dial-wheels, as in patent to Thornton, 1,146,371.

The cycling motor may be automatically set off as the carriage completes its traverse of a computing zone, by the usual dog (not shown) that is settable on a carriage-rack 73, and depresses the usual motor-trip lever 32 to release the motor-clutch 38 for cycling the machine. The trip-lever 32 when operated raises the usual link 33 to rock the bell-crank 34 and move a holding arm 34*- out of the path of a lever 35, to permit spring 36 to swing the lever 35 about its pivot and depress the slide 37 to release the clutch 38, thereby causing the machine to be cycled.

The automatic carriage-returning mechanism is fully described in the aforesaid application of Starck, and only such parts are herein shown as are necessary to illustrate the present invention. A projection 40 on the traveling carriage 13 depresses a pawl 41, mounted on the lefthand margin-stop 42, when the carriage encounters said margin-stop 42 at the end. of its forward travel. A margin-stop rack 43, loosely mounted on cross-shaft 44, is thereby swung about said cross-shaft and depresses the carriage-return-engaging link 45. This causes, by means not herein shown but described in said Starck application, the carriage 13 to be returned to the right-hand margin-stop 46. Adjacent said right-hand margin-stop 46, and shiftable therewith, is a dog 47 splined to the crossshaft 44. The carriage-projection 40 depresses the end of said dog 47 as the carriage reaches the right margin-stop 46, thereby causing the cross-shaft 44 to be rocked for disengagement of the carriage-returning mechanism, as also shown in said Starck application, the connections for effecting the carriage-return disconnection including an' arm 48, keyed to said cross-shaft 44, and a connecting link 49. The automatic carriage-returning mechanism thus briefly described is effective to return the carriage, so that the usual carriage-abutment 50 strikes the right margin-stop-abutment 51, after which the carriage drops back, say one and a half letterspaces, as determined by the amount of movement of the loose escapement-dog 14*.

It will be understood that the right marginstop 46 may be so set that as the carriage 'settles in its drop-back position, the work-sheet column in which the-date is to be printed is at the printing point, as shown in Figure 4. The automatic date-printing device is now brought into action, and will now be described.

A special type-bar 52 has a removable typecarrier 53, so that the type may be changed ac- V cording to the date. Said special type-bar 52 is .usual connections, including bell-crank 56 and key-lever 57. Rotation of a rock-shaft 58 at the rear of the typewriter is utilized to actuate the date-printing type-train, said rotation occurring as part of the operation of the computing-machine-cycling mechanism, operable by the motor 30 through'the clutch 38. As said cycling mechanism operates, the general operator 29 starts forwardly as indicated by arrow, Figure 9. The side of a notch 60 in said general operator thus forces a bell-crank lever 61 to rotate, and thereby shift a link 62 rearwardly, said link being connected to a bell-crank 63, which, in turn, engages an arm 64, fast to said rock-shaft 58. Thus, by to-and-fro movement of the general operator 29, the rock-shaft 58 is rotated. Said rock-shaft completes its rotation in one direction as soon as the general operator 29 starts forwardly, and is not restored to its original position until said general operator has reached the end of its return movement, the bellcrank lever 61 being unable to swing back until its end may drop into the notch 60 at the end of said return movement of the general operator. The to-and-fro movement of the general operator 29 and hence of the rock-shaft 58 requires a substantial time-period, and it is undesirable to keep the date-printing type-bar in operated position against the platen during this interval. For imparting a brief impulse to the date-printing type-bar train, the following mechanism is provided. Fastened. to the rock-shaft 58 is a downwardly-extending arm 66, whose lower end, having thereon a tab 67, may, through the oscillation of said rock-shaft 58 move forwardly and rearwardly. Said tab 67 may thus become effective to move forwardly a link 68, carrying a spring-pressed pawl-member 69 against which said tab 67 may abut. For enabling the link 68 to be moved into and out of operative relation with thetab 67, it may be pivoted at 70 to an arm 71, fastened to a shaft 72. An arm 75, in line with the type-action bell-crank 56,

and also fastened to rock-shaft 72, may be connected to said bell-crank by a link 74. It will now be seen that a forward movement of the tab 67 is effective, when the spring-pressed pawl 69 is opposite the tab 67 of the arm 66, to actuate the date-printing type-bar 52.

For automatically moving the link 68 and its pawl 69in and out of operative relation with the tab 67, the movement of the carriage is utilized by means of the following devices. A rock-shaft 76 may be-so mounted in bearings 77 that an arm 78, fast to said rock-shaft 76, may be actuated by a tappet 79, adjustably mounted on the carriage. The aforesaid rock-shaft bearing 77 may be secured to a cross-bar of the computing-machine frame. In order that the tappet 79 may by-pass the arm 78 in the return movement of the carriage, it may be formed as best shown in Figures 3 and 5, and swingably mounted on its supporting bracket 81, which, in turn, is adjustably secured to a cross-rod 82, forming part of the carriage 13. A spring 83 yieldably holds said tappet 79 against the bracket 81, and yields only as said tappet 79 overrides the rock- 'shaft arm 78 without rotating the rock-shaft 76 during the return movement of the carriage. The bracket 81 may be so positioned on the crossrod 82 that the tappet 79 has just overridden the arm 78 as the carriage reaches its extreme return position. Before the carriage drops back, the relative position of said tappet 79 and said arm 78 will then be as shown in Figure 5. As the carriage moves to its drop-back position in a letter-feeding direction, the end of the tappet 79 engages the arm 78, thereby causing rotation of the rock-shaft 76, and which rotation is utilized to bring the type-train-actuating link 68 into operative relation with the impulse-delivering arm 66.. To this end, said rock-shaft 76 may have fastened thereon a lever for connection by means of a link 86 to the rearward end of the type-train-actuating link 68. Said lever 85 may have two arms, one arm for attaching a spring 84, which keeps said lever 85 and connected parts in normal position by means of a stop-pin 88. The other arm of lever 85 has a pin-and-slot connection 87 to the upper end of the link 86. Said pin-and-slot connection permits rotation of the rock-shaft 76, and hence free carriage-movement, should the downward movement of the link 86 be temporarily obstructed, as, for example, when the tab 67 is under the pawl 69. In order to ensure that link 86 may move downward when free to do so, a spring 90, relatively weaker than the spring 84, may be applied to the upper end of said link 86. Through the action of the strong spring '84, the parts are held in the relative position shown in' Figure 1, wherein forward movement of the impulse deliverin'g arm 66 will have no effect upon the date-printing train. A

carriage-propelling spring 91 is of course strong enough to overcome the strong spring 84, so that when the carriage under the pull of said spring 91 drops back after the carriage-return movement, the rock-shaft 76 is caused to be rotated, the tappet 79, striking against the arm 78 at this time, effecting such rotation. The relation of the impulse-delivering arm 66 to the dateprinting train will then be as shown in Figure 2, wherein the tab 67 is opposed to the pawl 69. For offsetting this opposed relation of the pawl 69 and-the tap 67 after the date-printing train has received an impulse sufiicient to cause it to print, the link 68 may be caused to swing about its pivot-point 70, so that the edge of the pawl 69. escapes the edge of the tab 67. To this end, a projection 96 on the link 68 may encounter a cam 98, which cam may be interposed to effect such encounter by means of rotation of the rockshaft 58, the same rotation that efiects the impulse to the type-bar train. Said rock-shaft 58 may, therefore, have fastened thereto an arm 100, from which may depend a link 101, guided at its lower end at 102, and carrying said cam 98. Said cam 98 may be adjustably secured to link 101 by screws 103. It will be seen from Figure 2 that the relative positions of the linkprojection 96 and cam 98 may be such that a substantial movement, and hence impulse, may be delivered to the date-printing train before said train escapes from the tab 67 to complete its printing stroke by momentum. Figure 9 shows the position of the type-bar relatively to the platen at the time of such escape. In delivering this impulse, the impulse-delivering arm 66 will have moved from the position indicated' bythe dotted line 107, Figure 9, to the position indicated by the full line. Further movement of said arm 66 to the position indicated by the dotted.

line 108 may be idle, as far as the date-printing train is concerned.

The date-printing train having been set for operation, as indicated in Figure 2, the cycling mechanism is brought into action. This, too, occurs as the carriage 13 settles in its drop-back position after having been returned against the margin-stop 46. For starting the cycling mechanism into operation in this manner, there is employed a stop 110, settable along the toothed rack 73, carried by the carriage 13. In order that said stop may be efiective to actuate the triplever 32 for starting the cycling mechanism only permit said pawl to override the end of the lever 32, as shown in Figure 7. This overriding by the pawl 115 occurs as-the carriage nears the end of its return movement. After overriding the lever 32 and before the carriage reaches its dropback position, the pawl 115, under the influence of its spring 117, will have interlocked again with the stop 110, so that it is effective, during said drop-back movement of the carriage, to actuate the lever 32, as shown in Figure 6. The lever 32 will thus be actuated as the carriage settles in its drop-back position, the relative position of said pawl 115 and trip-lever 32 being then as shown in Figure 4. In this position the clutch 38 is caused to be tripped to operate the cycling mechanism, thereby rotating the rock-shaft 58 and actuating the date-printing train, as already explained. The date-printing train beingfree to escape after the type-bar has received sufficient printing momentum, it follows that said type-bar after printing may rebound normally, whereupon the carriage escapes, the pawl 115 passing from contact with the trip-lever 32, thereby ensuring termination of the cycling op eration. As the carriage thus escapes and proceeds in letter-feed direction, the tappet 79 may override the arm 78. In doing so the rockshaft may be caused to rotate and the tappetspring 83 may yield. Should downward movement of the link at this time possibly be obstructed, the pin-and-slot connection 87 is effective to co-operate with spring '83 to permit said overriding of the arm 78. Furthermore, should the tab 67 on arm 66 possibly be opposed to the pawl 69 in the return movement of said arm 66, said pawl may yield, for which purpose said pawl may have a cam-surface 92 and be provided with a spring 93.

In the machine in which the present invention is embodied, there is employed a skip-rack-device 119, referred to in the aforesaid pending application of Starck, and effective to automatically jump the carriage, after printing the date, into position for beginning typing of the item.

In employing the skip-rack-device 119, the re action between the teeth of the escapementpinion 112 and rack 113 may be sufficient to cause separation of said rack and pinion. To prevent this, there is employed a rack-holding member 120, fastened to the typewriter-frame and of sufficient extent to overlie a projection 121 of said rack during the time that the skip-rack-device is within its zone of action, said projection 121 being positioned accordingly on said rack.

The rock-shaft 72 may be journaled in a bracket 122, which may be secured to the crossmember 123 of the typewriter-frame. For guiding the link 68, at its rearward portion, against sidewise displacement relatively to the arm 66, the construction may be as best shown in Figure 8. To this end, said link may have secured thereto a bar 124 to form a space 125 within which the lower end of arm 66 may move freely, and the sides of which space thus formed prevent relative displacement sidewise of said link 68 and arm 66. The bar 124 may carry the projection 96. The link-member 68 may have formed thereon ears 126, on which the pawl 69 may be pivoted by means of a pin 12''! projecting through said ears, and around which pin the pawl-spring 93 may be coiled.

In the herein-described machine, the rockshaft 58 also serves to control the computing mechanism through the medium of the computing-mechanism arms 135, which are attached to said rock-shaft. Thus said rock-shaft 58, which, as already explained, is actuated by the computing-cycling mechanism, affords convenient means for attaching the arm 66.

The bearings 77, in which the rock-shaft 76 is journaled, may be secured to the cross-bar spanning brackets 137, which may be secured to the typewriter-frame. On one of these brackets 137, there may be pivotally mounted, as shown in Figure 1, the bell-crank 63.

As the by-pass p'awl 115 overrides the motortrip lever 32, as shown in Figure 7, sufficient reaction may be afforded by the train of parts, of which this lever is one end, by a spring 139, Figure 1.

The operation of the machine in which the invention is embodied is as follows. A bill 130 and a balance-sheet 131, interleaved with a carbonsheet (not shown), are in place around the platen, Figure 3. Upon typing the last balance on the balance-sheet, the carriage will have advanced to the left margin-stop 42, thereby depressing pawl 41 and thus setting the powerdriven carriage-return mechanism into operation, the carriage-return movement being accompanied by a line-spacing operation by means not shown, but described in the aforesaid Starck application. The carriage proceeds in its return movement until the carriage-abutment 50 strikes the right-hand margin-stop abutment 51. The cross-shaft 44 will then have been rotated, as the carriage-projection 40 has encountered the dog 47 on said cross-shaft, to disconnect the carriage from its returning mechanism. As the carriage 13 nears the end of its return movement, the tappet 79 will override the arm '78 Without causing rotation of the rock-shaft '76. Similarly the by-pass-pawl 115 on the carriage-stop 110 will override the end of the motor-trip lever 32 without operating said lever., After the carriage reaches the right margin-stop abutment 51, there is the usual recoil or drop-back movement, depending upon the extent of movement of the loose dog 14 of the carriage-escapement mechanism. At the end of said recoil or dropback movement, the tappet 79 is effective to cause rotation of the rock-shaft '76, thereby causing the link 68 to be raised (see Figure 2), so that it may be pushed forwardly by the arm 66, to effect operation of the date-printing bar 52. At the same time, that is, as the carriage reaches the end of its drop-back or recoil movement, the motortrip lever 32 will have been operated, thereby causing arm 66 to swing forwardly and the cam 98 to be raised, so that the pawl 69 may escape from said arm 66 just before said type-bar 52 reaches the platen. After said pawl 69, and con sequently the link 68, to which it is attached, escapes said arm'66, the date-printing type-bar 52 completes its stroke by momentum to print the date upon the work-sheet through a ribbon (not shown). The type-bar may then rebound freely, whereupon the skip-space-device 119 becomes effective to jump the carriage intoposition, beyond the date-colurrm, for starting typing of the succeeding item;

Where a new bill-form is started, it is necessary to also type the month in addition to the day. To this end, as set forth in said Starck application, the right margin-stop 46-may be temporarily set against collar 118. After typing the month thus at the beginning of a bill, said right margin-stop 46 may be reset against collar 114.

It will be noted that according to the present invention, restoration of the type-bar is not dependent upon completion of the cycling operation. Neither, therefore, need the .escape of the carriage be dependent upon the completion of *said cycling operation, and thus the date is automatically printed and the carriage tabulated to position for printing the first item almost immediately after initiation of the cycling operation, and substantially before said cycling operation is completed. It will also be noted that by providing means whereby the date-printing train is conditioned and the cycling operation is initiated only when the carriage has settled in its dropback position, all chance of printing the datefigure out of place on the work-sheet is avoided.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
