TYPE-WRITER.

SPECFXGATIGN forming part of Letters Patent No. 697,384, dated April 8, 1902. Application filed May 1, 1901. Serial No. 58,377. (No model.)

To all whom, t may concern:

Beit known that I, JOHN W. PAUL, a citizen of the United States, residing at Kittanning, in the county of Armstrong and State of Pennsylvania, have invented new and useful Improvements in Type-Writers, of which the following is a specification.

My invention relates to improvements in type-writers, and pertains to a machine of the visible-writing type and wherein the typebars are arranged in a substantially horizontal basket. v

The primary object of this invention is to provide a simple arrangement and construction of the type-bar action wherebya straight, easy, and practically uniform touch is effected.

A further object of my invention is to so construct the shifting mechanism for the vertically-movable type-bar basket that a quickacting and easy-touch shift is provided.

A further object of this invention relates to the construction and arrangement of the several parts of the mechanism hereinafter shown and described whereby an improved machine of the visible-writin g type is produced.

In the accompanying drawings, Figure l is a central longitudinal vertical sectional view of the machine embodying my invention, the carriage and the carriage mechanism being omitted, as that forms no partof my present invention. Fig. 2 is a detached perspective view of the type-bar basket with only a portion of the type-bars shown in position therein to more clearly disclose the specific construction of the basket and the arrangement of the type-bars. Fig. 3 is a top plan view on line 3 3 of Fig. l, the type-basket being omitted to disclose the type-basket-shifting mechanism and the universal-frame mechanism for effecting the feed of `the carriage. Fig. 4 is a sectional view on the line e 4 of Fig. 3 and looking in the direction indicated by arrow. Fig. 5 is a sectional view on the line 5 5 of Fig. 3 and looking in .the direction indicated by arrow. Fig. G is a central vertical longi* tudinal sectional view through the type-bar basket, the type-bars and key-levers being 5o omitted.

In a machine of the character herein shown there is essentially a horizontal frame A, hav- Y ing at one end the vertically-arranged standard B, upon .which is supported a suitable carriage, and situated within the horizontal frame A below the carriage is a verticallyshifting type-bar basket O, in which are arranged the type-bars and the key-levers.

The combined type-bar and key-lever bas-V Referring now to the construction and ar- `rangement of the type-bar basket, the typebars, and the key-levers, it will be noticed that one end of the type-bar basket consists of a block G, having grooves ZJ in its upper and lower sides, and located within these grooves are the type-bar division-plates c. Located between these division-plates are the type-bars H, which are'pivotally supported at their inner ends through the medium of a suitable rod d and carrying at their outer ends the type-bar block c, which contains the caps and small letters, as is well understood by those skilled in the art.

Projecting downward fromthe under side of the basket O at a point intermediate its ends is a vertically-arranged plate I, having in its under side a plurality of slots f, thus constituting a comb. The inner ends of the v L-shaped key-levers J rest in these slots f,

andthe outer portions of the key-levers are guided and moved in vertically-arran ged slots g', formed in a downwardly-projecting plate K, located at the opposite or outer end of the basket to that at which the .type-bars H are pivoted.

In a type-writer ofthe character here shown it is necessary that the type-bars be arranged in the arc of a circle and radially in respect thereto, and it is the primary object of my present invention to so construct and arrange the key-levers and the intermediate mechan-j /IOO ism between the key-levers and the typebars that although the type-bars travel in radii to the arc of a circle in which they are arranged, yet the key-levers will move in a vertical plane. This result is accomplished through the medium of the intermediate essentially L-shaped levers M, carrying at their inner ends suitable sockets t', adapted to receive and act upon the pivotal ends of the type-bars in a manner which is well known to those skilled in the art and need not be specifically described. At the intersection of the vertical portion Z of the L-shaped levers M a pivotal rod or other suitable pivotal support m passes for the purpose of forming a pivotal connection for the said L-shaped levers. The key-levers J are located at one side of the lower ends of the vertical portions Z of the levers M, and the key-levers are provided with laterally-projecting pins n, which project into suitable cam slots q, formed in the lowerends of the said vertical portions of the L'shaped levers M. By means of this construction when a key-lever is depressed the pin n thereof will by its engagement with the cam-slot q of the intermediate lever M cause its inner free end to move upward, and this upward movement will cause the type-bar H to be thrown up and against the printing-roller, as will be readily understood.

As before stated,the type-bars are arranged in the arc of a circle, and hence the intermediate levers M must be arranged to correspond with the type-bars. They are likewise arranged in the arc of a circle. The key-levers are arranged in a common horizontal plane, and owing to this arrangement of the key-levers it will be at once appreciated that the length of the vertical portionsl of the levers M will vary according to its location in order to reach 'the key-levers. On account of this construction the L-shaped intermediate levers M lying at or near the center of the type-bar basket have their vertical portions Zshort; but owing to the circular arrangement of the type-bars and these intermediate levers M it is necessary that the vertical portions Zof the levers M situated at opposite ends thereof be longer and be deected at a suitable point-for instance, at the point lr--to cause them to extend in a vertical plane.

Owing to the fact that the vertical portions of the levers M are of varying lengths and the desirability of having a uniform downward movement to the key-levers the inclination of the cam-slots q in the vertical portions of the intermediate levers M must of necessity vary. For instance, by referring to Fig. 2 it will be seen that the said slot q' in the central lever M is but slightly inclined, while the slots q in the end intermediate levers M are at a considerable angle. This is so for the reason that the longer vertical portions of the intermediate levers M must travel farther than the short portions of some of the other levers M in order to give the inner free ends the key-levers and assisting in the quick return to their normal positions I provide a spring for each of the key-levers. As here shown the form of spring consists of a doubled wire N, which passes through an opening s in the inner end of the key-lever, the ends of the said Wire passing through the openings t, formed inthe comb or plate I, the tension of the said spring serving to lift the outer free ends of the key-levers and to hold them in their normal positions.

The means for shifting the basket vertically for the purpose of writing in caps consists of a transversely-arranged pivotal bar 2, which has rigidly secured thereto an outwardly-projecting arm 3. The free end of this arm 3 engages the under side of a suitable shoe 4, which is attached to the block G and extends downward and inward and has its opposite end connected with the downwardly-projecting comb or plate I and serves the additional function of assisting in supporting the plate. Rigidly connected to opposite ends of the said pivotal rod 2 and eX- tending forward are the arms 5, which are rigidly connected with a suitable counterweight 6. This counterweight 6 is here shown in the form of a flat sheet or plate of lead or similar material and serves, through the me dium of the arm 3, which is in. engagement with the inner free end of the vertically-movable type-bar basket C, to lighten the heft of the inner end of the said type-bar basket.

Preferably I provide two shift-keys 7, the same being located at opposite sides of the machine, though, if desired, but one shift-key may be used. The inner ends of these shiftkeys 7 are pivotally connected to the horizontal frame A in any suitable manner at the points S and are intermediately connected with the outer ends of the arms 5 through the medium of suitable wire or other links 9.

When t-he typefbar basket is in position, its inner end, being in engagement with the inner free end of the arm 3, lifts the outer free ends of the arms 5 and in Vturn the counterweight (5, which is rigidly connected therewith, and through the medium of the links 9 also lifts the shift-keys 7 to their normal positions. A downward pressure upon either one of the shift-keys 7 will canse a corresponding downward movement of the counterweight and the free ends of the arms 5, and this in turn will lift the inner free 'end of the arm 3 and cause the lifting of the inner free end of the vertically-shifting type-bar basket.

ICO

For the purpose of enabling the'type-bar basket to be locked in its shifted position when writing a word or asentence in caps I provide any suitable form of locking lever or latch. As here shown I provide a lever 10, intermediately pivoted to the frame A, which lhas its lower end adapted to engage the upper edge of the-free end of one of thevarms 5 ofthe shifting frame, whereby when the said lever is moved inthe direction indicated by arrow in Fig. 4 it will cause a downward movement ofthe outer end of the shifting frame and 'ai corresponding upward movement of the inner end of the shifting frame, and' thus serve tobasket in the position tov lock the type-bar write in caps.

-The carriage-feed mechanism involves a universal frame, as is usual-in all type-writ` ers,fand thisuniversal frame as here shown is comprised of a pivotal rod'1`1, located at one end of the frame and below the carriage,v

outwardly-extending armsL 12, which are rigidly connected with vthe said rod 11, and a straight horizontally-arrangedYbar 14, which extends directly under the key-levers J and adapted to be engaged thereby when the keylevers 'are 'depressed' foi` the' purpose of oscil-v lating the rod 11, to which is rigidly connected the dog-supporting Iframe v15. From this descriptionit will 'be noticed that the uni! versal feeding-'frame is of'a rectangular -character and presents a perfectly-horizontal surface to the under side ofthe key-levers J and that there is -no'lateral-'or grinding action between the key-levers and the universal frame in the movement of the type-action of the machine.

'The'spa'ce mechanismhere shown consists of a U-shaped frame 16, which has its ends` pivotally connected at the points 17 to suit-V able ears 18, which projectfrom the frame A. The means whereby the movement of the space-bar16'is transferred to the universal feed-frame consistsV of an arm'l20`, which has its inner end 2l, as shown in Fig. 3,'loosely pivoted upon the rod 2 and vmovablelinde pendentthereon. This bar'20 curves upward and hasits outer end loosely inserted into an opening 22 of a depending arm 23, extending" be regulated relatively'to the movement ofV the key-levers, 'as some'operatorsdesire'an earlier feedof'the carriage in respect to the movement of the key-levers and the type-bar than others. This is `accomplished through the medium-of a bearing strip or plate 25,' which has one endf26'pivotally connected toy the said arm 20andits opposite end 26"con' structed to bevertically adjustable in respect to thesaid arm or lever 20through the mediumv of a slot and screw, as here shown at26;

The vertical movement of this bearingstrip orplate 25 will cause a correspondingmovement through the iengagement therewith of the barpli, constituting the inner end of the universal feeding-frame, andthu's cause acorresponding adj ustment'of the feed-dogs in relation to the carriage-rack.' Thisv vertical movement of the rod 14 willcause it to be nearer to or farther from the key-levers, thus regulatingthe period at which the feed of the carriage occurs relative to the Vmovement of the type-bars and key-levers.

I do not limit'myself' to thespecilic construction and specific arrangement of the parts herein enumerated, as these may be varied'by those skilled in the art withoutmaterially. affecting the spirit or scope of myinvention. f
