CHARLES S. LABOFISH, OF NEW YORK, N. ,Y., ASSIG-NOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Application filed June 10, 1918.

To all whom it may concern:

Be it known that I, CHARLES S. LABoFIsH, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to margin stop mechanism.

The main object of my invention, generally stated, is to improve such mechanism and provide. simple and efiicient means for affording an automatic control thereof so that writing may be produced at predetermined intervals within the margin.

In preparing various documents, such, for example, as specifications for applications of Letters Patent, it is desirable to number the lines. It is customary to number every fifth line within the re uired margin.

One of the more speci 0 objects of my invention is to provide means by which this may be readily accomplished. I To this end I have provided means by which the margin stop mechanism is automatically con trolled from the line spacing mechanism so that every, say, fifth actuation of the latter is operative to render the margin stops ineffective to arrest the carriage at its normal point of arrest, and permit it to move beyond said point to write the requisite number within the margin.

A further object of the invention is to provide means in the nature of an attachment that may readily be applied to existing machines on the market to effect the results stated without modifying, or materially modifying, the structuralfeatures of such machines as they now exist.

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the accompanying claims.

In the accompanying drawings, whereln like reference characters indicate corre-.

riage of an Underwood machine equipped with the devices of my invention.

Specification of Letters Patent.

Patented Oct. "7, 1919.

Serial No. 239,226.

Fig. 3 is a fragmentary top plan view partly in section of the parts represented in Fig. 2. I p

In the present instance I have shown invention embodied in an Underwood machine in which the invention may be readily V incorporated without changing, or materially changing, the structural features of. that. machine. It should. be understood, however, that the invention may be embodied in various otherstyles of machine with equal facility. I I

Only so-much of an Underwood machine; is shown as may be necessary to illustrate my invention in its embodiment therein. Thus the carriage,'designated as a whole bythe refercncenumeral 1, carries a cylindri-i cal platen 2 adapted to receive the usual case shlfting movement relatively thereto, the carriage being nonshiftable but mounted in the usual manner to travel from side to side of the machine over the top plate.

A line spacing wheel 3 is secured to the platen shaft 4. A line space pawl 5 is formed as a part of a carrier 6 pivoted at- 7 to a spring-returned slide 8. This slide. is mounted in a housing 9 on the left-hand side of the platen frame to slide fore-and-i aft of the machine. A leaf spring 10 is secured at one end, as at 11, to the slide and bears down at its free end against the carrier-6 of the line spacing pawl. This re-: sults in forcing the pawl to engage-the teeth of the wheel 3 when the adjustable controlling member 12 permits such engagement to erence numeral 13, is pivotally mounted on the carriage to turn on a vertical axis around a shouldered screw pivot 14. This hand lever is provided with a finger piece 15 by which it is actuated, and with a crank arm 16 which co-acts with the forward end of the spring returned slide 8. A movement of the finger piece 15 from left to right is efi'ective to actuate' the slide 8 and produce a line spacing movement of the platen. The

extent of this line spacing movement may be controlled in the usual manner by the setting or adjustment of the member 12 hereiiiheitore' referred to. Continued pres sure exerted on the finger piece results in the carriage-being moved'to the rig-ht until it is ar ested by-"a marginstop 17 on the carriage co-acting with the left-hand face of the usual adjustable margin stop 18 carried by the frame of the machine. The margin'stop 17 is forn'iedb'y the forwardly bent end of a lever 19 which extends long tudinally of and parallel with the'front cross bar 20 of the carriage, and beneath the forwardly extending flange 21 of said cross bar 'Theilever 19 is pivoted at 22 to the cross bar. and extends upwardly atits righthand end to form a finger piece or key 23.

A depression of the key is efiectiveto elevate the left-hand end of the lever against the force of a leaf spring 2-1, thus carrying the lever tojthe dottedline position where the stop 17 is moved out of cooperative relation with the stop 18.. The carriage may then be moved to the right beyond its normal point of arrest where the'stops :17 and 18 oo act, and is finally arrested by the. stop fire-acting with the final stop 25. The operator may thus at any time write within the margin by depressing the margin Tea 7 20 of the carriage. 501

lease'key 23. After the stop 17 has passed to the right of the stop 18, and pressure on the key 23. has been released, the stop 17 in the movement ofithe carriage to the left will contact with the right-hand bevel vface 26 of the stop 18 and be lifted and thus 'autoinatically pass the'stop 18 without ob? structing the movement ofwthecarriage.

The construction thus far described C011. st tutes part of the ordinary Underwood machine. r

In order to relieve the operator from the necessity of constantly bearing in mind how many lines have been written, and when it is necessary to write 1-16 number of a hne within the margin at given intervals, 1 have provided means for automatically releasing themar in stops at such given intervals, thus bringingthe carriage at once to the point where the number of the line may be writtenwithin the margin. Andthc very actof a carriage automatically 'moving be yond its normal pointof arrest is effective to warn the operator to write the requisite number within the margin before proceeding to write the line.

.The autoinatically operating means in normally extends into the path of movementv of the line spacing lever 13, as shown in Fig. 1. There are five teeth a, I), 0, (Z and e on the star wheel in the present instance, so that live 7..

intermittent movements transmitted to the Wheel by the line spacing lever is efi'ective to make'a complete turn of the wheel.-

"Secured to the rear face ofth'estar wheel 27 is e a rotative actuating device, cam or wiper, designated as a whole 'by the reference numeral30. This device in the present instance is formed with five faces, 7,7 0, 2' and Each of these faces oo-acts with the. flat upper edge 31 of a combined actuating and detent lever 32, tending to restore the Wheel 27 to andhold' it in any one of the diiferent positions to whichthe wheel may'ordinarily be moved, as will. hereinafter appear; I It Will be observed that the radial distance of all the surfaces or faces, f, 5], 7L

and i,,from the center of the wheel is the same, whereas theface 7' is formed on the end of an extension of the wiper 30, and its radial distance from the center of the wheel is greater than that of the other faces;

The lever 32 is pivoted on a shouldered pivot screw 33 secured tothefront cross bar 20 of the carriage. The right-hand end of this lever extends downwardly and then'upwardly to form a finger 3 1 which lies beneat-h theinner end of the release lever 19 in a position to co-act therewithto shift-tho latter tromthe. full to the dotted line position shown in Fig; 1. It should, be understood that the spring 24; is effective not only. to normally maintain the release lever 19 in the full line position in Fig.1, but also to exert its force through said lever against the lever 32 to force the left-hand end of the latter upwardly. The effect of this is to cause the flat face" 31 onthe lever 32 to bear againstone of the flat faces fig, h, t or of thewiper and tend to maintain the wheel in a position where one of the teeth thereon will be maintainedin the oath of the line s acin lever. V JD 3 as shown in Fig, 1.

While the spring 24: and the levers 19 and 32 may be sutficient in themselves to act as a detent mechanism for the purpose described Ipre-fer'to add a spring, detent-35 formed substantially as shown and secured. atone end, as at 36, tothe flange21. Thefreeend portion of this-spring is: adapted t0 bear" against the teeth of the star wheel 27 and tends to assure the movement of the wheel to, and to hold it; against accidental dis; placement from, any one of theseveralpositions it is to assume: 7 V c g i Let it be assumed that the parts are positioned as representedin full lines in Fig; 1. and that thefirst line has not been written. 'he operator will grasp the finger piece 15' moving it to the right therely' effecting a line spacing operation and returning the car- 'ri'age to the right to begin the first line. The efi'ect ofthis' is to turn the star wheel 27 one step, thus moving the detent face '5 out of cooperation with the lever 32 and bringing the detent face '71, into cooperation therewith; the spring-pressed lever 32 and detent spring 35 aiding in a completion of the-movement of the star wheel. This ad vances the tooth b one step to the former position of the tooth 0, and the tooth a will be brought to the former position of the tooth b, shown in Fig. 1. As the line spacing lever returns to its normal position it will co-act with the tooth a to effect a slight backward turning movement of the wheel sufficient to enable the line spacing lever to return to normal position without obstruction from the wheel. This slight backward clearing movement of the wheel is effected against the pressure of the spring detents, as will be understood from an inspection of Fig. 2. As soon asthe line spacing lever has, in its return movement, cleared the engaged tooth a of the wheel it will be slightly advanced again. by the spring detents to elevate the depressed tooth a into the path of the lever, so that on the next actuation of the latter the wheel may be advanced another step.

It will be understood that while this first step in the advance of the wheel effects a very slight movement of the'levers 32 and 19 on their pivots this movement is insufiicient to elevate the margin stop 17 to a point where it will clear the stop 18.

The intermittent movements of the wheel 27 and the member 30 will continue until the fifth line spacing operation has taken place when the wiper is brought to the dot-- ted line position shown in Fig.1, with the face co-acting with the lever 32. This results in moving the levers 32 and 19 to the dotted line position in Fig. 1, and in elevating the stop 17 to clear the stop 18 and enable the carriage to move beyond the normal point of arrest and to continue such movement until the stop 17 co-acts with the final stop The operator will then write the numeral 5 within the margin and continue as before until the tenth line spacing operation has taken place when the carriage has again automatically positioned to write the numeral 10 within the margin, and so on.

I have provided simple and efficient means by which the operator may, when desired, render and'maintain ineffective the automatically operating means for controlling the margin stop, mechanism. Thus, a controlling device in the nature of a screw 37, formed with a mutilated head, is threaded into a tapped opening in the front cross bar of the carriage. The mutilated head provides a flat contact face 38 which is adapted to co-act with the rear side of a tooth of the star wheel when the screw is turned from the position shown in Fig. 1 to that illustrated in Fig. 2. The efiect of this movement of the screw is to produce a slight backward movement of the wheel from the position shown in Fig. 1 to that illustrated in Fig. 2. This movement of the Wheel is sufficient, as will be seen from an inspection of Fig. 2, to maintain the teeth of the star wheel out of the path of the line spacing lever. Therefore, a movement of the lever at this time has no effect on the starwheel or the parts controlled thereby, and the automatically operated means are rendered and maintained ineffective or inoperative. \Vhen the screw is returned to the position shown in Fig. l, the detent devices Will return the wheel to its normal position, shown in said figure. At this time the teeth of the wheel may move freely past the flat face 38 of the mutilated head.

In the Underwood machine a full stroke of the line spacing lever is given irrespective of the extent of line spacing movement transmitted to the platenthereby. It Will be understood therefore that the automatic control of the margin stop mechanism is always the same, whether the regulating device for a line spacing mechanism be set for half spacing, full spacing or double spacing, and that this change in the character of line spacing does not affect the automatically opcrating means in any way.

' From the foregoing description it will be seen that I have provided simple and eflicient means of the character specified; that such means are in the nature of attachments that may be readily incorporated in existing machines without changing, or materially changin the structural features of such machines as they now exist, and that by the automatic control of the margin stop mechanism in the manner described I relieve the operator of the constant distraction due to the care which must ordinarily be exercised in numbering the lines, and in remembering to keep track of the given intervals when the lines should be numbered.

I have shown but one form of mechanism embodying my invention, but am aware that the invention may be clothed in various forms and may be variously modified to afford an application thereof to other styles of machines than that shown, and that such changes may be made without departing from the spirit and scope of my inventlon.
