24 claims. (ci. 19u-13a) This invention relates to typewriting machines, and more particularly to a motor actuated paper supply and paper receiving compartment carriage therefor, traveling to and fro in unison with the typewriter carriage, but propelled independently thereof whereby the typewriter mechanism may be relieved of load and strain. While it is old in this art to provide a rjeciprocatory paper carrier mounted in the rear of the typewriter and a reciprocatory paper receiver also mounted in the rear of the typewriter and actuated to and fro by the movement of the typewriter carriage, in the present instance the paper carrier is provided with propelling means independently of the typewriter by which the carrier is automatically advanced in unison with the movement of the typewriter carriage which acts as a governor restraining and controlling such advance movement. The paper carrier being automatically returned under motive intluence, carries with it the typewriter carriage preparatory to Y the next line writing operation. Such motor actuated return movement of the paper carrier and paper receiving carrier, and writing/v machine carriage, may be eiected by operation of the line spacing device o! the writing machine or by operation of a special key or lever that may be automatically arrested when the carrier and typewriter have been returned to a predetermined position.

The object of the invention is to improve the' construction as well as the means and mode of operation of paper supply and paper receiving' compartment carriers for writing machines, whereby they will not only be cheapened in construction, but will be more emcient in use, automatic in action, uniform in operation, and unlikely to get out of repair.

A further object of the invention is to provide a paper supply and a paper receiving compartment carrier for a writing machine which is propelled independently of but in unison with the traveling carriage of the writing machine and which will not subject the latter to undue stress or strain.

A further object is to provide a receiving compartment adapted to fold the material in its original zig-zag form.

A further object of the invention is to provide actuating means for a paper supply and a paper receiving compartment carrier for a writing machine adapted to impart thereto alternating motion, irst in one direction and then in the other.

A further object of the invention is to provide means for automatically returning the writing machine carrier inl unison with the return of the paper supply and pape: receiving carrie'r.

A further object of the invention is to provide au automatically traveling carrier for a paper ready on its way or in the paper receiving comsupply and a paper receiving compartment having propelling means other than the writing machine with which it is employed. 'Ihe movement of the carrier under its own motive powerin one direction is controlled by the operation of the writing machine, and upon actuation thereof in reverse direction it transmits return motion to the typewriting machine carriage.

A further object of the invention is to provide a unitary motor actuated paper supply and paper receiving compartment carrier applicable to different writing machines. v

A further object of the invention is Ato provide means for automatically eiecting the return of the paper supply and paper receiving carrier by the operation of the line spacing device of the writing machine.

A further object of the invention is to provide an improved actuator for the paper supply and paper receiving compartment carrier, and means whereby the actuator is intermittently connected with and disconnected from the carrier.

A further object of this invention is. to provide improved control means for the motor actuated paper carrier. l

A further object of this invention is to provide a locking means for the paper receiving compartment of the carrier whereby the written material may not be removed.

A further object of the invention is to provide a locked paper compartment for receiving the usedsheet, and provides mechanism whereby the paper may not be removed without properly unlocking the paper receiving compartment.

A further object of this inventionis to provide a tell-tale device indicating the withdrawal or tampering of the writing ,material without unlocking the compartment.

A further object of this invention is to provide a device for locking the paper advanced towards the receiving compartment only after a full blank has been written or used, thereby permitting the retracting of a portion of a blank in writing position without marring or defacing the paper alpartment.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the vinvention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and sei-H forth in the claims.

In Fig. 1 is shown a typewriter provided with a paper receiving compartment mounted on the same carrier that supports the paper supply. Fig. 2 discloses a piece of manifold material that may be used to advantage with this type of typewriter and receiving compartment. Pig. 3 dis- 10S another modification showing a paper comw partment that is locked. Fig. 4 .discloses a detail view of the delivery mechanism or guide intermediate the platen and the paper receiving compartment. Fig. 5 is a detail fragmentary view ofthe paper locking mechanism found in the paper delivery mechanism disclosed in Fig. 4. Figs. 6, 7 and 8 are enlarged fragmentary perspective views of parts of the driving mechanism. Fig. 9 shows cam release mechanism. t

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings, the reference character I is a conventional form of writing machine or typewriter having a traveling carrier 2 in which may be mounted the usual platen roll and provided with the usual line spacing mechanism including the operating lever 3 for advancing the platen roll through a step by step movement at the completion of succeeding lines of writing. The invention is likewise applicable to writing machines of the billing machine type wherein the traveling carrier moves the type relative to a stationary platen. It is to be understood that the invention does not depend upon the particular type or style of writing machine and that the typewriter disclosed in the drawings is employed merely for illustrative purposes.

Mounted in the rear of the writing machine for to and fro travel in unison with the typewriter platen carrier is a paper supply carrier 5 mounted in rearwardly inclined position upon a guide track 6 supported upon standards 1 arising from a base 8. The carrier 5 is provided with antifriction bearings 9 between its base and theV guide track 6. It is further provided with adjustable arms I0 extending on opposite sides of the reciprocatory carriage 2 of the typewriter, whereby the carrier and carriage are operatively interconnected for unison travel. i Such connection permits free vertical movement of a platen carriage as is ordinarily necessary with such carriage for writing capital letters and symbols when used but maintains the relative relation of the carrier and paper carriage during their to and fro travel.

Mounted upon a suitable dependent bracket I2 secured to the supporting track 6, as is illustrated more particularly in Fig. 8, is a spring propeller comprising a gear pinion I3 actuated by a convolute spring I4 and having operative driving engagement with a gear rack I5 carried upon the reciprocatory paper supply carrier 5. The propellerpinion I3 is loosely journaled upon a supporting stud I6 xedly secured to the-bracket I2 and slotted at I1 to receive one end of the convolute actuating spring I4, the opposite end'of which is secured to the propeller pinion. The

spring I4 is enclosed within a housing comprising a cap portion I8 having telescopic engagement with a circular flange or enclosure I9 upon the propeller pinion and surrounding the actuating spring I4.

The actuating spring I4 is tensioned or wound by the retractive movement of the paper supply carrier which, operating through the gear rack and pinion, imposes upon the spring sufllcient tension to drive the paper supply carrier through its range of movement in unison with the travel of the writing machine carriage. The spring actuator means, however, propels the paper carrier independently of the driving or power infiuence of the writing machine. The writing machine carriage operates as a governor to control the advance movement of the paper carrier under iniiuence of the spring actuator limiting it to a step by step movement determined in the usual manner by the Ioperation of the writing machine keys. 'I'hus while the traveling paper carrier moves in unison with the writing machine carrier, the latter is subjected to no strain Aor 5 load, and instead of affording the propelling influence as is usual in such combination, the writing machine carrier in the present instance affords a retarding influence, restraining the advance of the paper carrier and limiting its movel0 ment under in'iiuence of the spring motive means to' a rate of travel synchronous with that of the writing machine carriage.

In order to automatically return the traveling paper carriage after each line writing operation, l5 there is provided an electric motor 20 mounted for oscillatory motion in a suppOrting bracket or standard 2I and operating through a suitable speed reduction mechanism preferably, though not necessarily, of the worm gear type to drive 20 a friction wheel 22 having operative engagement with a friction bar 23 also carried upon the base portion of the reciprocatory paper carrier 5. The friction wheel 22 is intermittently moved into andvout of. driving engagement with the bar 23 25 by the oscillatory adjustment of the actuating motor 20. Such adjustment oiA the actuating motor together with the closing of the energizlng circuit is, as here shown but not necessarily, effected by the operation of the line spacing 30 mechanism controlled by the lever 3.

In the present disclosure there has been shown, merely for illustrative purposes, a vconventional type of line spacing mechanism wherein the operating lever 3 mounted upon the traveling car- 35 riage 2 is provided with a rock arm 25 connected by a link 26 with a rocker member or bell crank lever 21 connected by a reciprocatory link 28 with an actuating pawl 29 engaging the usual ratchet wheel upon the writing machine platen 40 roll. Such construction has been illustrated in Figs. 1, 3 and 6. In the present construction the rocker arm 21 is slldable to and fro upon a splined rock shaft 33 mounted in the frame of the writing machine. Thus the rocker member 45 21 which, in the ordinary writing machine construction, is pivoted directly to the traveling carriage, inthe present instance travels to and fro vupon the rock shaft 30 as the platen carrier is :reciprocated and is operated to rock such splined 50 rock shaft 3l! simultaneouslyv with the actuation of the spacing mechanism. That is to say whenever the line spacing lever 3 is manipulated to advance the platen roll, the rocking motion is transmitted to the shaft 30 through the rock arm 25, link 26 and rocker member 21, whatever the lineal position of the traveling can'ier may be. Secured upon the splined'rock shaft 33 is a rock arm 3I connected by a link 32 with a motor control lever 34 pivoted at 33 to. the frame of the 60 writing machine. The rear end of this motor control lever 34 is connected by a loose pivotal or slotted connection 35 with an arm 36 upon the oscillatory motor 2l. The oscillation of the motor control lever 34, under influence of the line 65 spacing mechanism to which motion is transmitted through the link 32, turns the actuating motor 23, in its mounting 2|, to engage the friction wheel 22 thereof with the friction bar 23 upon the base of the traveling paper carrier. At the 70 same time the forward end of the motor control lever 34 being depressed by the oscillatory motion of such lever closes an electric switch 31 thereby closing the motor energizing circuit 33 through a suitable source of electrical energy 75 and energizing the motor 2l to return the paper carrier. Adjustably secured upon the base of the paper carrier in such position as to engage the hub 3l of the friction wheel 22 is a cam 40 which, as the paper carrier reaches the limit of its return movement, operates to depress the friction wheel 22 out of driving engagement with the bar 2l by turning themotor 20 about its pivotal connection with its mounting-2| thus arresting the return movement of the paper carrier. This camming action of the cam 40 upon the hub 39 of the friction wheel 22 at the same time operates through the arm 36 to return the motor control lever 34 to its normal position thereby permitting the switch 31 Ato open,"de energizing the motor circuit. For economy of manufacture and simplicity of adjustment. the disengaging cam l0 is carried upon a`s1otied slide block li which straddles the bar 23 and is adiustably secured thereon by a set screw l2. By adjustment of the cam, the range of travel of the paper carrier 5- may be varied.

In the construction heretoforedescribed, there are employed two actuators or propellers, one of which comprises the spring actuated driving gear I3 propelling the paper carrier in one direction and the other comprising' the motor actuated friction wheel 22 propelling the paper carrier-Jin reverse direction. The retracting motorhas suilicient power to overcome and rewind the actu-v ating spring il 'of the primary propelling pinion I3, whereby the latter is retensioned at each retractiveoperation preparatory to the next line writing operation. Not only does the motor 2lil possessl suihcient power to overcome and rewind the primary actuating spring, but it. also serves to automatically return in unison with the paper carrier the traveling writing machine carriage with which the paper supply carrier is operatively connected for unison travel. Thus while the writing machine carriage controls fthe paper carrier during its operative movement in one direction, the paper carrier in turn propels the carriage during its retractive movement. Although the actuator for retracting the traveling paper carrier is preferably controlled by the operation of the normal iine spacing mechanism of the writing machine, as has been heretofore described, it may, if desired, be controlled vby a special key and to this end the forward extremity of the motor control lever 14 has been provided. with a head lla by which the lever may be manually depressed to tilt the motor 2l to effect operative engagement of the. friction wheel 22 and bar 23 and at the saine. time close the motor circuit switch 31.

'I'he above device is fullydisclosed and described in my copending application, Serial No. 584,321, led January 2, 1932. In the above referred vto application, a paper supply carrier has been disclosed.

- In the modication disclosed in this application, a paper receiving compartment Il supported on the carrier i receives at least a portion of the used paper as it is delivered from the type-` writer. lIhis permits the Opelwr to make copies of the bills, statements, invoices, or whatever may be used on the machine, and deliver the carbon copies in the paper receiving compartment' Il without depositing each one individually andmanually. In order to facilitate the delivery of the paper from the platen to the paper receiver- Il, a guide I4 suitably carriedon the arms il has one end located near the platen of the typewritingmachineand theotherendextendingun.

over the paper supply carrier 5. Thus the paper is delivered directly from the platen to the paper receiver 5I.

In the modification disclosed in Figs. 3, 4, 5 and 7, the typewriter mechanism and the driving mechanism for the paper carrier and the paper receiver is identical. However, in the modification disclosed in Fig. 3, the paper supply carrier BI is mounted underneath the paper receiving compartment C2. The paper s'upply carrier ill is provided with an open end 64 through which the paper supply is withdrawn and fed to the platen roller of the typewriting machine and returned through a suitable guide i5 that is preferably completely enclosed as best seen in Fig. 4 13 so as to supply the carbon copy to the paper receiving compartment $2. In some cases, both the ribbon and carbon copies may be delivered to the paper receiving compartment. Whenever it is desired to prevent the operator of the typel writer from tampering with the written material which has already been supplied to the paper receiving compartment 62, Vit is desirable to lock the compartment 62 so the operator cannot open the compartment. A suitable lock 8l, carried by the paper receiving compartment 62, is used to lock the closure 82 in position so that the closurel 82 cannot be opened without the use of a key M. When this is done, it is also desirable to provide a tell-tale or lock so that the paper cannot be 30 withdrawn from the compartment 62 without being mutilated. In the present modification this has been accomplished by providing a pair of pawls or dogs 66 pivotally mounted at 68 to the brackets 10 carried by the cover I2 of the paper 35 guideii. These dogs or pawls 66 are so situated as to engage apertures 14 and 16 in the manifolding material paper 'I8 disclosed in Fig. 2. Preferably the dogs 66 are so positioned that the distance from the platen roll to the dogs i6 is at 4o least equal to the length of one blank so that it is possible to withdraw or retract the blank on the typewriter platen to make corrections thereon;

but as soon as this blank is advanced into vthe ing position. The pawls Ii serve as va tell-tale j by mutilating the writing material whenever the withdrawal of the written copies through the guide lI-is attempted, so thatthe proper authorities may be apprised of the fact that anattempt l hasbeen made to tamper with the written record.

vIi'roln theforegoingitmay-bereadilyseenthat it is impossible or practically impossible for the operator of the machine. without the use of the key Il, to remove the written material from the receiving compartment I2 without such removal being detected. Although the receiving compartment hasbeen disclosed in connection with a typewriter, it could be used with a billing machine, or any other machine for making records on paper which is stored in a suitable compartment.V Instead of the pawl engaging the apertures 14 and 1I usually punched in the paper for filing purposes, the pawls Si could, of course. be arranged to engage the pin holes SI in the edges of the writing material, but this would not permit the retraction of the-blank that is being writtenuponinthemachine. Itisalsopossible to provide dogs havim suitablev teeth to engage tbepaperwhenpaperisused thatisnotpro- 1s vided with punched holes for filing or feeding purposes.

The guide 54 is so arranged with respect to the paper receiving compartment 50 that a mani'- fold material advancing from the writing position through the guide 54 is automatically stacked in the original zig-zag formation in the receiving l compartment, 50. This is very desirable as thereby a minimum amount of space is required in the receiving compartment.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be ,understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modications within the legitimate and valid scope of the appended claims.
