SPECIFICATION formingpart of Letters Patent N o. 6l 1,146, dated September 20, 1898.

Application iletl September 16, 1897. Serial lTo. 651,929. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM P. QUENTELL, acitizen of the United States, residing at New York, in the county and State of NewYork, have invented new and useful Improvements in Type-'Writing Machines, of which the following is a specification.

The object of this invention is to obtain a type writing machine capable of being cheaply made and the invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a plan view of the machine with the paper-roller sectioned off. Fig. 2 is asection along the line ao, Fig. 1. Fig. 3 shows a key-guiding plate. Fig. 4 is a detail view of a type-segment-actuating lever and adjacent parts. Fig. 5 is a section along the line y y', Fig. 2. Fig. 6 shows the carriage in side elevation and in printing position. Fig. 7is a section along the liney y, Fig. 2. Fig. 8 is an enlarged detail view of the paper-roller or platen-carrier and supporting devices and of the lever mechanism which prevents the paper-carriage touching the paper to the type when the spacing-key is actuated.

A base or support 1 by suitable risers 2, Fig. 2, carries a rod or fulcruln 3 for the keys or levers 4 5. The lever-arms 4 are provided with the iinger-buttons 6, and the lever or key arms 5 are engaged by restoring-springs .7, which return the keys when released, as known. From base 1 extend risers 8, carrying a guide or slotted plate 9 for guiding or steadying the keys. In the drawings are shown two sets of keys, one setbeing on each side of the median line ocx; but the explanation of one key-set will explain the other.

Under each key-set extends an arm or crossbar 10 of a lever 11, having its fulcrum 12 at a suitable base part 13. As seen in Figs. 1 and 4, the levers 11 can be steadied byhaving their f ulcrum parts 14 doubled or bail-shaped. Each such lever 11 may for convenience of de scription be called a main or carrying7 lever, carrying the fulcrum 15 of what may be called a secondary lever 16 17. Thesecondary-lever arm 16 by means of a lug or engaging part 18 engages orlifts. the lever 1l. Said lever-arm 16 has a stud or fastening 19,

ytoward the depressed key-arm.

to which is engaged a spring 20, secured to a suitable fixed point or arm, as 21, Fig. 2, on the machine-base. The spring 2O drawing or moving lever-arm 16 to carry the lug 18 to the lever 11, such spring 20 will lift or return the lever 11 when the parts are free.

The lever-arm 17 has a slot-and-pin connection 22 and 23, Fig. 4, with an arm 24 of lever 24 25, fulcrumedvat 26. Of course the pin 22, which is shown on lever-arm 17, might be placed on lever-arm 24 and the lever-arm 17 be slotted instead of the lever-arm 24. Such changes are obvious', as any suitable loose connection between -the lever- arms 17 and 24 can be made to answer.

The lever-arm 25 rotates the type wheel or segment. This arm 25 engages a shoulder 27 on a disk 28, Fig. 5, and said disk 28 is fixed to shaft 32, to which shaft is also iixed a plate 29, Figs. 2 and 5, which by arm 30 engages the type wheel or segin ent 3l, mounted loosely on shaft 32. The disk 28 thus actuates the type-wheel, since when' a lever 24 25 swings it engages one or another of the shoulders 27 and rotates disk 28, which rotates the shaft 32 and plate 29 with arm 30 and type-segment 31. The disk 28 has oppositely-located shoulders 27 for the engagement of the respective levers or arms 25 as the wheel is to be rotated in one direction or another.

The type-Wheel 31 is mounted on shaft 32, and the rotation of said wheel is suit-ably arrested by an arm or stop 33. This stop 33, like disk 28, is xed to shaft 32, and when the machine is at rest this arm 33 lies between the key-sets, as seen in Fig. 1. In mentioning type-wheel a type-segment is of course also naturally understood or included.

A depression of a key-arm 4 depresses the corresponding lever 1l, carrying down the V secondary-lever fulcrum 15, as also said secondary lever 16 17, against the resistance or tension of spring 20, and such descending lever 16 17 by the stud or joint 22 23 swings the lever 24 25, so as to rotate the type-Wheel and swing arm 33 to carry its free end 34 This free end 34, striking such depressed key-arm, is arrested, together with the type-wheel, and as a key-arm is depressed which is more or less removed from the median line x the arm 33 and type-wheel 31 rotate more or less be- IOO fore 4being arrested. Naturally the arrangement of characters or type on the wheel is such that when the arm 33 comes to stop against a depressed key-arm the character which has been turned or carried by the wheel to the printing-point corresponds to that keyarm 4 or button 6 which has been depressed. The key-arms 4 are normally so high that the arm or stop 33 can swing past under the keyarms, as seen in Fig. 2, and by suitably bending or thickening the free end 34" of arms 33, Fig. 2, such free end 34 will be prevented from missing or slipping `past a depressed key or losing its engagement with such key until released or until the printing is completed. The stop-arm 33 and disk 28 being separately fixed or secured to shaft 32, the arm 33 can be set to correspond to the higher or lower level at which the keys may be set in different machines, and the disk 28 can be set for proper engagement by the lever-arm 25 or by the free end of such arm. After the arm 33, with the type-wheel, is arrested by a depressed key such key continues its down-` ward travel to effect the printing stroke, as presently explained. The type-wheel having been arrested, as stated, the disk 28 holds the lever 25 24 against further motion; but the secondary-lever fulcrum 15 continuing to descend with the main lever 11 and the slot 23 and pin 22 forming a loose joint, which allows play, or the stud or stop 22 being free to play in such slot,the secondary lever swings about such stop or stud 22 during this further descent of fulcrum 15, so as to swing the lever arm 16 downward against the tension of lifting-spring 20. This secondary lever 16 17, while normally a first-class lever with fulcrum at 15, may, during this further descent of fulcrum l5, while lever 25 24 is fixed, be considered as temporarily a third-class lever with the fulcrurnv at 22, the power-point at 15, and

4the resistance-point at 19 or at the spring 20.

On the release of the depressed key the tension of spring 20 draws the lug 18 on leverarm 1G against the main lever 11 with such force as to raise or return the main lever to its position of rest.

The disk 28 in addition to the shoulders 27, Fig. 5, has also the shoulders 35, and when a lever-arm 25 is rotating the type-wheel said arm 25 engages or lies between said shoulders 27 and 35, and the disk and wheel are rotated one way or another by said lever swinging back and forward. When the parts are at rest, the lever-arms 25 lie clear of and forward of said shoulders 27 and 35 and alongside a tailpiece 28', Figs. 5 and 6, extending forward froln said disk 28, and in this position neither lever-arm 25 offers any obstruction to the other lever-arm actuating the type-wheel; but said lever-arms 25, both lying against tail 28', act as a centering device for holding stop-arm 33 at the startingpoint or median line. When the tail 28 lies in normal or central position, as shown in Fig. 5, either lever-arm 25, when swinging backward, will clear or move past tail 28 to strike the corresponding shoulder 27. Say, for example, the right-hand lever 25 in Fig. 5 swings backward, and, striking its shoulder 27, swings the type or printing face of wheel 31 to the left and the tail 28 to the right. By this right-hand swing of tail 28' the shoulder 35 on the right is carried to the right, so that when the right-hand lever 25 now returns forward it will strike this right-hand shoulder 35, so as to return the tail 28' to the median position, where this right-hand lever 25 can clear such right-hand shoulder 35 to return to rest.

The paper roller or platen 37, Fig. 2, together with guide rod or roller 38 for the sheet or paper 39, are journaled or mounted in a carriage 40, the foot 41 of which travels in a suitable way or guide 42 on arms 43, which are movably supported, as by pivots 44, so that they can swing the platen, with the sheet 39, toward the type or segment for executing a stroke or print. The arms 43 have a cross-bar 45, Figs. l, 2 and 6, extending across the machine underneath or into engagement with the main levers 11, so that as one or another of the latter is depressed it descends onto the cross-bar to swing the arms 43 about the pivot or fulcrum 44 and carry or swing the platen to the type-segment. The carriage 40 or its foot 41 carries a feedrack 46, Fig. 7.

Pivoted to the way 42 at 47 is a swinging plate 48, having at its rear a lip or turned-up shoulder 49. Pivoted or fulcrumed to this plate at 50 is a pawl 51 52, and as this pawl swings about pivot 50 in either direction such swings are limited by either pawl- arm 51 or 52 striking this shoulder or stop 49. The spring 53 holds the plate 48 toward the rack 46 and the 4spring 54 holds the pawl toward such rack. The spring 53 extends from the way or base 42 to the plate 48 and the spring 54 extends from this plate to the pawl.

An arm 55, Fig. 2, is suitably fixed to the base 1, and as the platen-carriage swings or falls back or away from the type-segment the plate 48, Fig. 7, or its nose 5G comes to rest against the arm 55, and the plate is swung against the tension of spring 53 to carry the pawl away from the rack 46. The spring 54 then swings the pawl to bring its arm 51 to rest against the stop 49, this swing of the pawl being suiiicient to bring the pawl-arm 52 into position to wtake into the next succeeding tooth of rack 46, when the plate 48 again swings toward the rack upon the platen, moving toward the type. The spring 53 is powerful enough to not only "swing the plate 48, with the pawl', to the rack,

but also to swing pawl-arm 52 to the stop 49 against the resistance of spring 54. This swing of pawl-arm 52 to the stop 49 after said pawl has taken hold of the rack 46 causes the rack, with the carriage, to be fed along for one step or tooth, and when the spring 54 has drawn the pawl to the rack and the pawl-arm 52 is braced or stopped against the stop 49 IOC) IIO

the pawl holds the rack, with the carriage and paper-roller, against motion on the way'42.

The sides of the carriage, as seen, form bearings or supports for the roller 37, and these sides, as well as the carriage-front 57, Fig. 2, rise from rack 46. This front has cutout portions bent to form tongues or guides 58 for leading or holding the paper 39 about the roller. The sides are cut through the rear edge, as seen at 59, Fig. 2, such cuts 0r slots allowing the roller to be slipped into and removed from the carriage. Springs 60, suitably applied, hold the roller toward the carriage-front.

The ribbon-spools 6l have ratchets 62, Fig. l, for the engagement of pawl 63, pivoted at 64. Springs normally hold the pawls to the ratchet. One pawl or another can be locked out of action, as by a suitable peg or other holding device, and in Fig. 1 the pawl 63 at the left-hand side is shown out of action, while the opposite pawl engages its ratchet 62. The pawls 63 have theirpivots 64, carried by arms 66 67, swinging about the shafts of spools 6l.

/Vhen the carriage swings forward, the way or track 42 strikes the tail or end 66 of the arms 66 67 to swing the latter and shift the active pawl 63 one tooth along the respective ratchet 62. On the return of the carriage and of the arm 66 67 with the active pawl the corresponding spool 6l is turned for feeding the ink-ribbon. The springs 65 are arranged not only to hold the pawls 63 in action, but also to return the arms 66 67.

A spacing-lever 68 69, Fig. l, passes under or clear of the levers l0 l1, so that the depression of this lever will not actuate the type-wheel, but said spacing-lever, engaging cross-bar 45, will swing the carriage or the arms 43 sufficiently to clear plate 48 from arm 55, but not so far as to drive the paper 39 to the type. The plate 48, being cleared from arm 55 and then being returnedto rest against said arm, will vibrate the pawl 5l 52 to feed the carriage the distance of one rack-tooth, as already stated.

The type-segment with two or more rows of type, as required, can be lifted by one or more levers 70, Figs. l and 6, to bring lowerl type-rows into action.

Ahammer 7l, Figs. 2, 6, and 7, is carried by an arm or gooseneck 72, fixed to way 42. When the carriage swings or flies to the type, the hammer-head 7l presses the printingpoint of the paper or sheet 39 to contact with the required type.

The spacing lever or key G9 engagesa cross bar or rod 73, connecting the arms 74 -of levers 74 75, fulcrumed at 76, and when the spacing-key is depressed the lever-arms 75 are thrown toward the way 42 to prevent the paper-carriage striking or touching the paper to the type. As seen in Fig. 8, each lever 74 75 is somewhat of the shape of a bell-crank lever, so bent that when the arm 74 swings row of type into action.

downward the arm 75.swings backward or toward the way 42.

To obtain a clear impression, the hammer or-head 7l can be advantageously faced with a soft rubber cap or like soft material, as by slipping a rubber tube or band over such hammer-head. At the same time the stroke of the hammer vcan be further softened by the paper 39 being doubled between the hammer and the type during the greater period of writing, as seen in Fig. 2.

The levers lift the type-wheel 3l by means of the angular arm 77 78, Fig. 6, the branch 7 3v of said arm engaging the grooved metallic hub 79, Fig. 2, to which the y.typewheel is secured .or about which hub such wheel is fixed, such wheel being hollow and having its top, bottom, and periphery made of light materialas, for example, one piece of hard rubber. TheA branch 77 of said arm passes through upper and lower guide-plates S0 and SO and rests on the levers 70. Set or stop screws 8l, Fig. 6, variously adjusted in the lower guide-plate SO', limit the play of each lever 70, so that as one or another of the levers 70 is depressed the wheel is shifted to bring the middle or lower row of type to the printing-line. type is the one used, such top row being at the printing-line when the levers 70 are at rest. A set-screw or adjustable rest S2 limits the drop or descent of branch 7 7 or of the type-wheel as required for bringing the top A spring S3 tends to return the arm 77 7 S when the levers 70 are free.

The type-wheel 3l slides or moves longitudinally on the shaft 32, while the latter has no longitudinal motion. Rotation of the Normally the top row of ICO IOS

shaft 32, as already seen,is imparted to the type-wheel by the plate 29 and arm 30. The plate 29 has its periphery provided with or formed into concentrically arranged Y- shaped guiding-slots, as seen in Fig. 5. A yielding or spring arm or lever S4, Fig. 2, is placed in the path of the carriage-way 42, so that as the way swings toward the type the lever or lock 84 is brought into engagement with one or another of the slots to set or lock the plate 29 and type-wheel with the required type in proper position for a clear print.

The slotted plate 9 by having a second slotted plate or plates 9', Fig. 3, adjustably secured thereto, as by screw-and-slot Vconnection, can have the width or size of its slots or passages regulated to accurately fit or guide the keys. supposing the slots in plate 9 are so wide as to allow the front ends of arms 4 to wabble or rattle, by setting plate 9/ laterally a suflicient distance such lateral play or excessive looseness of arms 4 can be remedied. Of course plate 9 must not be set so tight against arms 4 as to bind or interfere with the proper play or function of the keys.

The top guide-plate S0, as seen in Fig. l,

IIS

extends across the machine and has depressions or cut-outs back of the points or shoulders 85. Should either of the arms 66 or pawls 63 swing to a greater extent than the space of one of the teeth of ratchet 62, the respective shoulder 85 on such excessive forward swing will lift pawl 63 away or clear from the ratchet, and the pawl 63 on its return or backward swing will only take into the ratchet G2 at that point of the travel of the pawl as to cause the spool 61 to rotate the space of one ratchet-tooth.

The ink-ribbon, as known, can suitably extend from one spool to another, being suitably held before the faces of the type.

The shaft 32 can be suitably steadied or held to base l by a screw 86, Fig. 6, set into a suitable part or riser 87 of the machine or of the plate 80. To keep the paper 39 in position or from falling forward, arms 88, Fig. 2, can be placed on the way 42 on each side of and close to the printing-point. Such arms can be formed from sheet metal.

The front 57 can have a scale stamped or printed directly thereon. In Fig. 9 is shown a piece of front 57 with a scale indicated thereon.
