TYPE-WRITING MAC-HINLQ SPECIFIGATION forming part of Letters Patent N o. 690,715, dated January 7, 1902.

Application ined June 22. 1900;

To a/ZZ whom t may con/cern:

Be it known that I, ROBERT JOSEPH FISHER, a citizen of theAUnited States, residing at Ath# ens, inthe county of McMinn and State of Tennessee, have invented a new and useful Type Writing Machine, (Oase 13,) of which the following is a specification. ,f

This invention relates totype-writing machines, and particularly to the construction and arrangement ot' the type-bars thereof to provide a low keyboard, visible writing, and a permanent alinement of the type with a minimum number of. parts and low cost ofconstruction. In the attainment of these results the invention primarily contemplates a modification of the construction and arrangement of type-bars disclosed in my compau ion application, (Oase A,) Serial No. 21,206. While accomplishing all of the advantagesof the construction set forth in thefsaid other application, the present invention provides a novel manner of mounting and arranging the type-bars and their operating-shaft portions, whereby the type-bars are arranged at right angles to the/axis of rotation of theirV operating-shafts i' and may be Yreadily Y grouped in such a way as to provide a wide work-vista at the front of the type-basket to permit of a view of the writing from the front of the machine. Y

With these and otherobjects in view,which will hereinafter more fully appear, the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed. t

The improvements forming the subjectmatter of the present application are necessarily susceptible to modification without departing from the scope of theinvention; but the preferred embodiments of the improvements are shown in the accompanying drawings, in which- Figure 1 is a plan view of a type-writing machine embodying the improved type-action. Fig. 2 is a front view of the machine. Fig. 3 is a vertical longitudinal sectional view thereof. Fig. 4 is ahorizontal sectional View illustrating the grouping and arrangement of the type-bar-operating shafts and omitting the other parts of the machine for the purpose of clearlyexposing the construcserni no, 212207. ,uit model.)

tion. Eig. 5 is a detail 'view showing a few of the individual bearings about the typebasketv opening. Fig. 6 is a detail in perspective of one type-bar and its connections.

Like numerals ot reference designate corresponding parts in theseveral figures of the drawings. p

The present invention relates solely to the construction and arrangementof the typebars in such a manner as to entirely dispense .with the usual hanger-ring or support for the type-bar bea-rings, while at the same time providinga single direct operating connection between the type-bar proper and the keystem associated therewith. This improvement is necessarily susceptible to embodiment in almost any form type-Writing machine; but it is preferably utilized in the construction of a book type-writing' machine of the .type shown in my former patents, Nos. 569,491 and 573,868. The general form of the machine produced by embodying the novel construction and mounting of the type-bars is fully disclosed in the companion application, (Oase A,) Serial No. 21,206, hereinbefore referred.to,and a specic detailed description of the auxiliary appurtenances of this machine is not Vdeemed necessary in the present case. It isof course understood that in the carrying out of the invention the type-actio n, including the type-bars and the operating parts therefor,is necessarilyca'rried by any suitable support; but for illustrative purposes the type-action, like in Oase A, is shown in connection with a book type-writing machine having a traveling type-carriage l, which is supported for travel in connection with suitable carriage or frame rails 2, cooperating with the maintrack-rails 3, which are asso-` ciated with the type-writing-maehine support or table 4, one of said carriage-rails 2 or the frame of which it forms a part carrying the usual line-spacing mechanism 5. As shown, the type-carriage l consists of a shallow or low casing provided with a at base or door 6, the iuclosing side and front walls 7 andS, respectively, and the top cover 9 of the usual stepped form ation, over which is arranged the keyboard.

. The improvements forming the subjectmatter of the present application are designed to be associated with a suitable type- IOO basket opening within which the type-bars are grouped and which is open and freely exposed to permit of a clear view of the work, and in the horizontal form of carriage illustrated in the drawings the latter is provided in its rear side with a rentrant crescent or approximately semicirculartype-basketopening 10. This arrangement of the type-basket opening within the rear side of the carriage permits the type-bars to strike rearwardly, thus permitting the carriage to be advanced forwardly or downwardly from the line of wri ting as the work progresses.

The present invention involves as an essential feature thereof the employment of a single type-bar 1l, provided with an operat-l ing-rock-shaf t portion 12, rigid therewith, so that for all practical purposes each type-bar and its operating rock-shaft will be of one piece. By reason o f this construction each type-bar practically consists of the single bar or arm portion 1l and the operating-shaft portion 12, which move in unison and are operated by a direct key connection therewith. The type-bar and the operating-shaft may be constructed of one piece of material; but in the practical construction thereof the operation of welding will probably be resorted to to effect a rigid union between the type-bars and their shafts.

In adapting the type-bars and their operating rock-shafts to a horizontal type of machine, such as shown in the drawings, the said operating-shafts are all arranged in horizontal planes parallel with and in close proximity to the base or floor of the carriage-casing, thereby dropping the entire type-action into close relation to the writing plane. It is by reason of this arrangement that a very low keyboard may be provided in carrying out the present invention. The operating rockshafts 12 for the type-bars extend forwardly from the type-basket opening 10 within the carriage-casing, and the type-bars themselves e are grouped in a crescent form within the typebasket opening at the edge thereof. The said type-bars by reason of being disposed at direct right angles to the axis of rotation of their operating-shafts 12 will normally stand in vertical positions when at rest, and by grou ping the type-bars in separate side banks or groups, which is rendered possible by the novel arrangement of the operating-shafts hereinafter more fully described, there is formed or provided at the center of the typebasket between the separate side banks of the type-bars a widened work-vista 13, which permits of a clear view from the front of the typecarriage into the type-basket opening 10 upon the writing or printing. p

Each type-bar 11, or, more properly speaking, the operating rock-shaft 12 thereof, is provided with a pair of, widelyspaced bearings 14 and 15, respectively, which bearings simply consist of bearing brackets or plates arranged in upstanding positions and having formed therein bearing-openings 16 and 17,

respectively, which receive the opposite extremities of the operating rock-shaft associated therewith, and at this point it is to be observed that the bearing-openings in the widely-spaced bearings14 and 15 foreach rockshaft are arranged in direct alinement and are interseeted by a common plane, so as not to interfere with the free oscillation of the rock-shaft; but in order to permit of the rightangular disposition of each type-bar tothe axis of rotation of its operating-shaft the operating-shafts for all of the type-bars excepting the type-bars at the very center of the type-basket are provided with laterally deflected or bowed portions 18, which sweep about the type-basket opening and permit of an exceedingly close grouping of the shafts, so that the straight portions of the latter may be brought toward the center of the carriagecasing into close or overlapping relation, as shown in Fig. 4 of the drawings.

The individual bearings 14 for the ends of the rock-shafts 12 contiguous to the typebars 11 are grouped in circular'series about the type-basket opening 10 and are seated, by means of a flange or other suitable connection 19, at the edge of the type-basket opening cut in the base or floor 6 ofthe typecarriage, as may be plainly seen from Fig. 3 of the drawings. ings 15 are arranged remote from the typebasket opening in order to secure a maximum length of bearing for the individual type-bars, and inasmuch as most of the operatingshafts are longer than the type-bars proper the latter are positively prevented from any material play at the striking-point, which would interfere with the alinement of the type. The said individual bearings 14, located about the type-basket opening 10, are arranged side by side in as close relation as possible, with the bearing-openings 1G in their upstanding portions disposed in a direction to aline with the openings in the complementary individual bearings 15, remote from the type-basket opening; but in order to provide for the close grouping of the operating rock shafts 12 within the bottom portion of the traveling type-carriage the said individual bearings 14 are necessarily of diiferent lengths, so that the bearings for opposite sets of operatingshafts for the opposite banks of type-bars are necessarily arranged in different planes, which permits of the operating rock-shafts for the opposite banks of type-bars crossing each other in different horizontal planes, so that there is no interference between the shafts and their connections. This is plainly shown in Figs. 3, 4, and 5 of the drawings.

It will be further observed that the arrangement of the type-bar-operating shafts in the present case is quite similar to that disclosed in the other application, Case A, aforesaid; but it may also be noted herein that the series of operating rock-shafts 12 for one side bank of type-bars extend forwardly from the typebasket opening in divergent relation and are The other individual bear-` ICO ICS

disposed in one general direction, While the operating-shafts for the opposite side bank of type-bars bear a similar divergent relation to each other, but are disposed in an opposite. direction toward the center of the type-carriage, whereby all of the operating-shafts will be bunched as closely toward the center of the carriage as possible. Most of the divergently-arranged operating rock-shafts for the opposite banks of type-bars will therefore necessarily cross cach other,but in different horizontal planes, in view of the. different planes-in which the individual bearings 1l are arranged.

The key connections are all alike, and the` With a short crank-arm 22, fitted to one end of the type-bar-operating-shaft 12, associated therewith.l This single and direct connection of parts is plainly shown in Figs. 3 and 6 of the drawings, and in connection with each type-bar-operating shaft there is also employed a resetting or retracting spring 23, coiled upon the shaft and arranged to normally exert a torsional tension in a direction for returning the type-bars to their upright positions after the type has been struck'and the pressure of the finger relieved from the key.

The letter-spacing mechanism 24 and the yokes or universal connections 25 for such mechanism are fully disclosed in the other application, (Case A,) so further reference there to is unnecessary in the present application.A

The construction set forth in this application constitutes one of the many modifications which might be resorted to in the grouping of the type-bar-operating rock-shafts in close compact relation to permit of direct key connections therewith, so it will therefore be nnderstood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of theradvannected to said type-bar, and a key for operating said shaft and disposed in a plane above the same.
