TYPE-W ITING MACHIN E.

SPECIFICATIQN forming part of Letters ramlilo. 698,318, dated A rnea-woa Application filed May 29, 1901.;

To all whom it may conceiva- Be it known that I, WILLIAM P. QUENTELL,

a citizen of the United States, residing at Manhattan borough, New York city, county of New York, and State of New York, have invented new and useful Improvementsin Type- Writing Machines, of which the following is a specification.

This invention resides-in certain novel features of construction set forth in the following specificationand claims and illustrated in the annexed drawings, in which- Figure 1 is a plan View of the machine. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a section along a; :20, Fig. 2. Fig. 4 is a section along y y, Fig. 2. Fig. 4 is a plan view of the type-wheel-driving segment. Fig. 5 is a sectional side elevation of Fig. 1, showing Fig. 6: Fig. 7 shows a the type-wheel in the art of printing. is a section along 2 2, Fig. 5. plan view of the machine with a type-arm havingperforations or engaging portions by which 1 such arm can -.be not only stopped, but also The reference-numeral 6 denotes suitable risers or supports for the centers of a shaft 16. This shaftl6'is conveniently formed in two sections, which when'in the machine the said sections have their inner ends joined by or mounted in a frame 30, which can be provided with suitable hub or recessed parts for seating the inner ends of the opposite see- On the shaft 16 are sleeves or bearings 17, Fig. 1, of levers or arms 19, Fig. 2,-eonnected by link 19 with lever or rather bail 18, Figs. 5 and 6, actuated by the key-levers. Two levers 19, with their respective parts, are shown; but the description of one explains the other. As one lever 19 orthe other is actuated it strikes a shoulder 20, Fig. 4, on shoulder or disk 21, Figs. 1 and 2, so as to oscillate this piece with SerialNo. 62,410. (N oinodel.)

rock shaft or sleeve22, carrying arm 23, with segment 24 engaging gear 25 of the typewheel or its shaft.v As the gear 25 is oscillated one way or another, with disk 48 having connection by means of pin 26 with the type-wheel, the latter is turned or set to bring a required type to the'printing position.

The type-wheel shaft 27 is shown with a sleeve" 29 rotating with gear 25 and carried by frame 30, vibrated, as presently explained, for the printing stroke. With this sleeve rotates a pinion 37, engaging a segment 36, having an arm 39, adapted to be stopped or arrested by the pins 18, each of which is lifted or moved to stopping position by its respective key-lever when depressed.

When a key-lever is depressed, it lifts a pin and actuates levers Band 19, which latter rotate the type-wheel and pinion 37, so as to swing stop-arm 39 until stopped by the pin,

which has been raised or brought by its respective key to arresting position. After the rotation of the type-wheel is stopped the continued pull of

levers

10 and 18 causes frame 30 toiswingso-as to dipor strike the typewheel againstthe platen.

The arm39 and row 'of pins 18, extending each side of thecenter line of the machine, are shown not parallel with one another, but in curved relation to one another. It is evident that thelarm and; pins must be so arranged that the wheel can turn. more or less to bring the required type to printing position before the arm or the rotation is stopped. The arrangement shown ofa straight row of pins and a stop Qarm with curved parts or branches or curved face'tocontact With the pins extending toward each side of the machine has been found compact 5 but of course forming such inner end, are adapted to lift or release a locking-bail 43, which is adapted to engage hook 4.4 or a depression in said hook, Fig. 5, and prevent premature tiltingof the type-wheel. On a key being depressed its pin 18' starts rising, and the respective lever 19 being actuated by link 19 and arm 18 will rotate the type-wheel, such rotating being stopped at the proper moment by arm 39, swinging right or left, striking the raised pin. The inner end of the key lifting or unlocking the stop 43 at the proper moment further depression of the key, with the resulting downward pull of link 19', will draw the frame 30, with wheel 1, to the platen. When the stop or bail 43 engages the arm or depending part 44 of frame 30, the latter is locked against vibration, so that the type'wheel cannot dip.

The spacing arrangement may be of any suitable kind, such as rack 47 and dog 46, actuated by arm 50, which latter is moved by the key-levers.

The pinion 37 is shown brought close to the center of vibration or shaft 16 of the typewheel, so that the printing stroke will cause but slight vibration or shift of the pinion and loss of mesh with the segment or gear 36 is avoided. The segment 36, with its arm 39, has its pivot or fulcrum independent of the typewheel-carrying frame 30, and such pivot can be mounted or carried on a comb-plate or any suitable riser or part of the machine.

The ribbon or inking device is not shown, as any suitable ink-roller will do.

The case-shifting movement of the typewheel or its shaft 27 can be effected by a lever-arm 55, fulcrumed at 56.

The arm 48 is secured to a suitable part of the machine, and during printing the toothed disk 48 engages this arm to lock the type wheel or secure accuracy.

The levers 19 when at rest or in normal position lie against stops or screws on frame 30, and a stop 66 limits the upward swing of the type-wheelthat is, the backward swing of arm let. These stops can be readily made adjustable, for example, by forming them of screws.

In order to lock the type-wheel when arm 39 has struck a stop and the wheel begins to dip, a lever, as shown at 67, Fig. 2, can be applied. This lever or blade is made to normally drop or spring to engagement with disk 48 of wheel 1, Fig. 5; but when this wheel or its frame 30 is raised or in normal position the blade 67 is held out of action to have wheel 48 and segment 1 rotate. When, however, frame 30 begins to dip, the blade 67 is carried away from stop 68, so that the blade will engage the toothed wheel 48. The stop 68 is readily formed by a screw placed in a bridge or cross-piece 69.

When arm 39 strikes a stop or pin 18' and arrests the axial motion of the wheel, a rebound may occur in case the key is struck very hard. Such rebound occurring just at the moment that frame 30 begins to tilt, the locking lever or blade 67 drops into a space or notch in disk 48, thus preventing the rebound being communicated to type-wheel 1, and when the disk 48 engages arm 48 the type-wheel is held against oscillation, so that a neat print is assured or blurring avoided.

A modification is shown in Fig. 7 by which a rebound on the arm 39 striking a pin 18 can be prevented. According to this modified construction the stop-arm 39 has a beveled or inclined edge or face 39, and on coming against a pin said arm or its bevel slides or rides up on top of the raised pin until such pin locks or engages an eye or suitable part 70 of the arm to lock the latter and prevent rebound. The arm 39 is thus locked until the key is released or the pin 18 drops. The arm 39 can yield or spring so as to ride with its beveled face over or rise onto an elevated stop-pin, or such stop-pins can each have a spring or yielding support 10 resting on its respective finger-keys, so as to snap at the proper moment into a perforation or locking part of the stop-arm. The toothed disk 48 with pawl 67 at the type-wheel and the looking arrangement for preventing rebound of the stop-arm when striking a raised stop-pin can be used separately or can be applied together in one machine. It maybe noted, how ever, that a lock preventing rebound of the stop-arm has been found sufficientin making practical tests. M

As seen in Fig. 7, the beveland locking eyes do not extend entirely up to the pivot-point 36, since in practice it has been found that the inner portions of arm 39, having to travel only a comparatively short distance before being arrested by a stop 18, do not rebound or at any-rate so slightly as not to require a lock.
