TYPE-WRITING i MACHINE.

SPECIFICATION forming part of Iietters Patent No. 458,241, dated August 25, 1891.

Application iiled December 3l, 1889. Serial No. 335,472. (No model.)`

Atype-writers in which the printing characters are arranged on a sector or wheel, and the objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a substantially central vertical section of a type-writer constructed in accordance with my invention with parts in elevation. Fig. 2 is a detail of the type-wheel carrier. Fig. 3 is a plan of the type-wheel carrier with the type-wheel and locking-wheel removed and showing the normalizing-wheel and end views of the type-wheeloperating segments. Fig. 4 isa plan of the lockingfwheel. Fig. 5' is an elevation of the trip-lever bail, showing the series of trips arranged thereon together with the segment-bail, and its adj usting-screws arranged in their relative operative position.

Like letters refer to like parts in all the iigures of the drawings.

A is thetype-wheel, having in thisinstance three rows of printing characters thereon, either one of which rows may be brought into the printing plane by means of a key-lever A', pivoted to the base, as at A2, and extentiing under a pin A3, passing through and projecting from the shaft A4, on which the typewheel A is mounted, and secured by means of the thumb-screw A5. The spindle or shaft A4 is mounted in a carrier or sleeve B, which is bifurcated at its lower end, and each of the bifurcations is perforated for the passage of a shaft B, to which the carrier is rigidly at tached by pins B2, or other suitable means. Between the bifurcations the shaft is supported by means of a bracket Bsecured to one piece thereon.' The wheel G has teeth C', separated by slots C2, which are adapted to receive a locking blade or post C3, rigidly mounted on the base and serving to lock the type-wheel against rotation after the desired printing character thereon has been brought Amounted on the carriage Y of the machine. As post C4 projects from the wheel C through a' hole in the type-wheel to rotate the latter when elevated to bring different rows into the printing-plane. The wheel D is a normalizing-wheel, and consists simply of a disk having a single broad tooth or projection D', adapted to enter between the projection F7 on the wheel-operating segments, hereinafter described, when the type-wheel is at rest and atits farthest distance from the platen. The wheel E is an ordinary gear-wheel, having in this instance ten teeth, although the number of teeth may be increased or decreased, as desired.

F F represent segments, each having in -this instance Vfive teeth, which number may be increased or diminished, as desired, but preferably maintained at exactly or about one-half of the number of teeth in the wheel E. These segments are arranged on the shaft B', one on each side of the carrier C, and unlike the carrier are mounted to oscillate on the shaft. The carrier B is rigidly secured to the shaft and oscillates with it. The oscillations of the segments F F are produced by means of 'the bails F2, each of which extends along under one-,half of the series of key-levers of the machine. These bails comprise a bar F3 and two rods F4 and F5. On the bar F5 of each of these bails are suspended a series of trip-levers G, having two arms G and G3, the short arms G of which are, by coiled springs G2, mounted on the rod F4 of the bail, held normally in contact with the loweredge 0r other suitable part of a key-lever H of the machine.

l represents a bail extending the complete length of the machine and under the entire series of key-levers thereof. It is provided with adj usting-screws I', one for each trip-lever G. The bail I has arms I2, which are'rigidly connected with the shaft B', so that when the bail I is depressed the shaft is oscillated, and with it the carrier and type-wheel, and

opposite the'printing-point of the platen X;`

the latter is thrown against the platen to make an impression. The bails F2 are connected with the base by coiled springs F6, which bring them to their normal position after having been depressed, as hereinafter described.

The operation of the invention is as follows: Upon depressing a key-lever I-I the shorter. arm G of a trip-lever G is depressed against the tension of its coiled spring G2 until said short arm is brought into contact with the bar F3 of the bail F2. In this movement the longer arm G3 of the trip-lever is thrown opposite or into line with but not into contact with that adjusting-screw I of the bail I which is arranged in the path of the trip-lever, which it takes when carried down byk further depressing the bail F2. The movement of the key-lever as thus far described gives motion to the segment F or F and rotates the type-wheel to bring the desired type thereon opposite the printing-point, the typewheel and its carrier being not tilted toward the platen until by a further depression of the key the long arm of the trip-lever is brought into contact with the adj usting-screw I. The locking-wheel C contacts with the locking blade or standard C3, from which time the cylinder is carried toward the platen with Aa type at the printing-point. To determine which type shall be brought to the printingpoint, all that it is necessary to do is to simply adjust the screw I, when the key-lever for that type is depressed, so as to bring it to the desired point. One of the segments F F gives the type-wheel. a half-revolution in one direction and the other in the opposite direction, and on the return movement of the segments the type-wheel is brought to its normal position, and is stopped in that position by means of the extension or lug F7 on each of the segments which comes into contact with the tooth D of the normalizing-wheel D.

By the construction and mode of operation above described I utilize to an advantage that which has heretofore been a great obstacle in type-wheel, cylinder, or segment-machines-that is to say, the momentum of the wheel has been an obstacle in the production of rapid printing. The moment the trip-lever G makes contact with the adjusting-pin I of the segment-operating bail and the segment has shifted with the gear-wheel E the momentum of the bail expedites the movement of the segment and the momentum of the segment eXpedites the rotation of the Wheel, and the aggregate momentum of both expedites the oscillation of the parts to produce an impression on the platen. Momentum also aids in bringing the segment-bail in contact with the oscillating bail after the segment has meshed with the gear. It Will be noticed that during the first portion of a depression of a key-lever the segment rotates the type-wheel and engenderstherein momentum, and that as soon as vthe trip-lever comes into contact with the adj Listing-screw the engendered momentum of the type-wheel is utilized as so much force applied to the work of tipping the Wheel toward the platen. This follows because the type-wheel is locked against further rotation when the trip-lever is in contact with the adj usting-screw. The means whereby it is locked consists in the rigid connection of the arm i2 and the carrier B with the shaft or rod B and the loose or pivotal connection of the segment F of the bail F3 and its eX- tension F2 constituting a part of the bail. In other words, the segment-bail F2, arm I2, and carrier B all become practicallyparts rigidly connected with the shaft or rod B', and any momentum of the type-wheel lnust be expended in carrying these parts toward the platen. Of course this momentum is utilizable only in the operation which takes place at each separate depression of a key-lever. If the character to be selected employs in this machine an adjusting-screw I which projects but a slight distance above the bar or bail I, then the momentum engendered in the rotation of the wheel assists in a more marked degree in bringing the trip-lever into contact with said adjusting-screw than when said screw projects to normally reach said lever. This characteristic of the inode of operation of the mechanism shown and described has reference to features which are extremely delicate in action and which must be capable of extremely-rapid movement. The problem involved has reference to the operation and effect of the momentum engendered in a body, which, though extremely light, is given an extremely rapid movement. rlhe combination and arrangement which I have adopted, shown, and described have in actual use demonstrated successfully their capability of utilizing a hitherto objectionable characteristic of machines of this class.

Certain features of my inventionare applicable to other classes of type-writing machines than wheel-machines. I therefore do not confine the invention to a use of the same in connection with type-wheel or segment machines, but reserve the right to embody the same in type-writing machines generally, and in which said mode of operation may be embodied.

It will be noted that in the operation of this invention the segments are first oscillated for a time which is determined by the adjustment of the screws I nearer to or farther from the trip-levers, whereby a greater or less rotation of the printing device is produced before it and the segments are simultaneously oscillated. In this manner any desired type may be brought to the printing-point.

The reciprocating mechanism of the printing device in this invention consists of the projecting pin or pins A3 and the lever A. The rotating mechanisms consist of the gear E, segment F, and bail F2, or any ordinary bail connected with the segment. The oscillating mechanism comprises a carrier or sleeve B, in which the spindle of the printing ICO IIO

IZO

device is mounted, and any ordinary bail I- that is, a bail Without the screws I.

Heretofore in this class of machines, the oscillating mechanism began to act immediately upon the commencement of a depression of akey-lever; but in this instance the printing device is not oscillated until after the commencement and until near the end of the stroke or depression of the key-lever. This is a very important feature of construction and mode of operation in that the momentum of the parts put into operation at the commencement lof a stroke is utilized for, in part, making the impression, and thereby not only relieving the touch of the machine and entire labor of oscillation during the commencement of the stroke, but also reducing the labor when actually performed to the extent that the momentum of the parts rst operated acts on those subsequently brought into action. The tipping or oscillation of the printing device does not occur until after the rotation of that device is completed.

The rotating mechanism can operate only when the oscillating mechanism is at rest, or, in other words, when the carrier of the printing device is at rest. As soon as the carrier moves the rotation of the printing devicev carrier toraid in the easy depression or touch and to increase the speed Vof the machine. This it does, for the printing device being operatively connected with the segment and the latter with the rotating bail any momentum of the parts mentioned will only try or serve to make the printing device turn faster in the direction it is Aimpelled by the nger-stroke, which will urge the segment forward so much quicker, and through that the trip-lever will be so much quicker to touch the adjustingpins in the oscillating bail, and through it tip, tilt, or oscillate the carrier and the printing device and print. The locking-standard is set so near the wheel that the moment the carrier starts forward, as described, the form is locked for the particular letter. This is another advantage, because no matter how perfect the mechanism when one has to contend with momentum it is necessary to insure against tremor at the moment of entering the lock, because the failure to do so will oset the speed secured from momentum or otherwise, and the tremor of the form will show in the writing. In my arrangement of the locking devices the printing wheel or device is under the induence of the locking-blade C3 a triiie before it stops rotatingthat is, when the bladeis in the wider space between the teeth of the locking-wheel, so that it cannot fail to enter the locking-slots between the teeth just previous to the instant of impression.

As to the interposition of tripping-levers between the rotating and oscillating mechanisms or bails, I would state that in their absence, and in bringing the key-lever directly in contact with both bails successively and in the substitution for the tripping-lever any particular 'conformation of the bails themselves or of the key-levers'for the purpose of timing the contact of the latter with the former, so as to produce successive operation of the rotating and oscillating mechanisms, the impulse given to the two bails would absolutely and materiallyV vary, as I have found by experience, and so create a momentum that would vsend the first bail so far forward that it would be in advance of the position wanted when the key-lever touches the second bail for printing. This has been the trouble with all previous constructions of which I have a knowledge. I therefore provide and interpose the trip-levers, so that the key-lever touches only one bail, and that is set for a certain rotation of the printing device when it touches the second or tiltingbail, communicatin g with it whatever of momentum it has acquired, and beyond that making the running away of one bail from the other mechanically impossible.
