MORGAN DONNE, OF LONDON, ENGLAND.
SPECIFICATION forming part of Letters Patent No. 582,605, dated May 11, 1897.
Application filed October 19, 1895. Serial No. 566,215. (No model.) Patented in England N0.11,331 of 1891 and No. 6.806 of 1892.
To all whom, it may concern-.-
Be it known that I, MORGAN DONNE, manager of the works of Norths 'lype-VVriter Man ufacturing Company, Limited, a subject of the Queen of Great Britain, residing at 57 ,Hatton Garden, London, in the county of Middlesex, England, have invented certain new and useful Improvements in Type-VVritin g Machines, (for which I have obtained Letters Patent of the United Kingdom No. 11,331 of 1391 and No. 6,806 of 1892,) of which the following is a specification.
The improvements relate more particularly to that class of typewriting machines in which the type-levers are arranged in the arc of a circle facing the operator and in which the printing-point is located between the typelevers and the keyboard, but some parts thereof are also applicable to other forms of type-writing machines; and the objects of the present invention are, first, to provide a simple and efficient means for supporting and guiding the paper-carriage in its movements; secondly, to mount the paper-carriage and couple it with the shifting-bar in such manner that itwill be more truly guided and better supported than heretofore, so that there will be no possibility of its springing when in its extreme position and throwing the printing-point out of alinernent, while at the same time it will travel more smoothly and with greater steadiness; thirdly, to form and arrange the hangers for the type-levers in such manner as to afford broad bearings to the latter; fourthly, to provide a means of readily raising the inking-ribbon guide, together with the inking-ribbon, in order to give an uninterrupted view of the printing when required; fifthly to provide an efficient means for adjusting or regulating the length of the connecting-rods between the key-levers and the type-levers, and, sixthly, to form the papercarriage in such manner that it will be lighter, more rigid, and cheaper to produce than here tofore; and in order that the said invention maybe clearly understood and readily carried into effect I will proceed, aided by the accompanying drawings, fully to describe the same.
In the drawings, Figure 1 is a transverse section representing a type-writing machine constructed according to the present invenan end view thereof.

Fig. 32 is a plan thereof. Fig. 33 is an elevation of one of the end plates separately, and Fig. 34 is a vertical transverse section taken on the line 5 5 of Fig. 33.
In the several figures, in which like parts are indicated by similar letters of reference, Figs. 2, 15 to 28, and 30 to 34 are drawn to an increased scale with respect to the other figures of the drawings.
Referring to Figs. 1 to 29, a represents the base of the machine, which is preferably formed of malleable cast-iron, and which, according to the first part of the present invention, is provided with four vertical lugs or posts a, which are cast thereon, two being arranged on each side of the base a and each having formed therein a vertical transverse slot or saw-cut a In connection with these vertical lugs or posts a two horizontal bars or girders Z) are employed, which are formed at or near each end thereof with a downward lyprojecting lug 1), adapted to fit the slot at and the vertical post a, so that both the girders Z) will extend transversely of the base of the machine and lie parallel to each other, and the girders Z) are fixed to the vertical posts a by means of rivets or screws b These girders 1) form the supporting means for the papercarriage hereinafter more fully referred to, and the method of construction above described enables the same to be made more accurately and at less cost than if the girders b were cast in one with the base a, inasmuch as any fitting in connection therewith can be performed prior to fixing the girders I) in position upon the base (0.
According to the second part of the pres ent invention, 0' represents the platen-cylinder, which travels with the paper-carriage in the usual way.
0 represents the paper-holder, which is of the well-known skeleton kind, and c represents the scroll or receiver into which the printed paper is received and stored after passing over the platen-cylinder c, and 0 rep resents the end plates, which are fixed with the parts hereinbefore described by means of rods or bars 0, and which parts constitute the upper carriage.
(Z represents the transverse bars or girders of the frame of the lower carriage, and (1 represents longitudinal bars thereof which are lixed therewith, and these longitudinal bars (Z are formed with grooves (Z therei mar-ranged longitudinally upon the outer and vertical faces thereof.
The two girders Z1, which are arranged transversely of the machine, but longitudinally of the carriage at the front and rear thereof, are similarly provided with grooves b upon their inner faces, as shown more particularlyat Figs. 1, 2, 3, 7, and 10, and within the grooves U (Z are fitted two or more hardsteel balls 0, upon which the carriage travels for letter-spacing, stops (P I) being provided at the ends of the grooves Z1 (1 in order to prevent the balls 6 working out of place,
as shown more particularly at Fig. 12.
Forconvenience three balls care employed, two arranged in the grooves (l at the rear of the paper-carriage, and one located in such grooves at the front of the paper-earriage, as shown more particularly at Fig. 12, but in this latter case the groove Z)" in the girder I) at the front of the paper-carriage is formed for a correspondingly short distance in the center thereof, but is of suffieient length to admit of the proper traverse of the single ball 0.
Eeneath the lower edge of the grooved bar (1 at the front of the paper-carriage, and carried by the corresponding fixed girder b, are arranged, just clear of the lower edge of the grooved bar (1, two rollers 0 mounted upon studs or axes Z1, and the offiee of these rollers Z) is, in the event of excessive pressure being brought to bear upon the the paper-carriage, to further assist to support the same and prevent it unduly springing.
In order to support and guide the upper carriage in its to-and-fro movements to shift the printing-point, each end plate 0 of the upper carriage is at each extremity formed with a horizontal groove or race 0, and the end transverse frames or girders (l of the lower carriage have lixed therewith, by riveting, short bars of steel (1, each formed with a short horizontal. groove or race (1", corresponding with the grooves c of the end plates 0, and hardened-steel balls (9 are arranged in the recesses or races formed by the grooves c (1 so as to admit of the necessary shifting movement of the upper carriage while truly guiding and steadying the same.
The shifting-lever fthat is to say, the lever moving forward the upper carriage so as to shift the printing-point-usually carries at its upper end a circular rod or shiftingbar which is embraced by a grooved bar resting thereon; but this arrangement gives rise to considerable friction and is therefore objectionable. According to the present in vention, however, the grooved bar c", which is fixed with the upper carriage, is still retained, but instead of the circular rod carried by the shifting-lever f a second grooved bar f or shifting-bar is substituted therefor, as shown more particularly at Figs. 13 and 1t, and the two grooved bars, which are internally furnished with stops c andf are so arranged that together they form a race for several balls c, which constitute the connection be tween the two bars 0 and f, and thus the necessary coupling is obtained between the uppercarriage and the shifting-barf with the least possible friction in the traversingof the compound carriage. By this arrangement of parts the paper-carriage is caused to travel with greater faeilityand truth, and by reason of the greater steadiness with which it is held the printing is much improved.
According to the third part of the present invention, and as shown more particularly at Figs. 20, 21, and 22, the table h for the hangers of the type-levers g, which is segmental in shape, is formed with a step or with two tiers of bearing-surfaces 7t h arranged at different elevations, and the hangers M are arranged radially side by side thereon, as hereinafter more fully described.
The hangers ij, as shown more particularly at Figs. 23 to 28, are formed in the shape of forks at one end spread out to form broad bearings to the shafts or axes g of the type bars or levers g, and they are at that point formed with cups or recesses t" j, and the ends of the axes g of the type-levers g are correspondingly cupped to receive hardenedsteel balls e, and sensitive antifriction-bearings are thus formed for the type-levers g. lhe hangers 2' j are at their opposite ends contracted and held together by bolts or rivets t j so as to form apertures t j to receive vertical bindingscrews 11* 3*, which pass through the apertures i j and enter corresponding holes formed in the tables 77, 72,2, respectively, combination-washers 1 7'*' being interposed between the heads of the bindingscrews 6* f and the contracted ends of the hangers e' j.
In order that the type-levers 9 may be placed close together, so as to obtain a compact arrangement of the parts and yet have the advantage of the broad bearings, the expanded or hearing ends 2" of the hangers "L of the upper tier are formed alternately cut away at t upon their upper and under sides, as represented more particularly at Figs. 23 and 25, so that they will overlap one another, and thus lie close together at their contracted ends, as shown at Fig. 20.
The hangers j of the lower tier kg of the segmental table h are arranged with their expanded or hearing ends j directed toward the corresponding ends t" of the hangers t' of the upper tier, and the contracted ends of alternate hangers j of the lower tier, whose bearings j for the type-levers, by the overlapping formation of the hangers, are placed at a lower level than those of adjacent hangers, are formed of a reduced height, as represented more particularly at Fig. 28, so as to allow a clear passage for the type-levers g, while the adjacent or overlapping hangers are cut away at 7' in a similar manner to that described with respect to the upper tier of hangers t' and as represented more particularly at Fig. 26, and the contracted ends of the overlapping hangers of the lower tier are preferably reduced, as represented at in Fig. 26, with a similar object to that described with respect to the reduced height of the lower hanger represented at Fig. 28.
According to the fourth part of the present invention, and as represented more particularly at Figs. 1, 2, and 29, a small thumb-lever Z is mounted upon an axis of motion Z at the side of the keyboard and is provided with a tail or offset Z which acts upon one end of a lever Z mounted upon an axis of motion Z, and at its other end pivotall y connected by a link Z with an oifset l from the ribbon-guide 1 which is mounted upon an axis of motion Z By this arrangement of parts when it is desired to raise the ribbon-guide Z and inking-ribbon, in order to give a clear and uninterrupted view of the printing, it is only necessary to depress the thumb-lever Z, when, through the lever Z and link 1, the guide Z will be raised into a vertical or approximately vertical position, as represented by the dotted lines in Fig. 29, carrying with it the inkingribbon, the square end 1 of the ofiset Z of the leverl acting, in conjunction with the corresponding end of the lever Z as a stop to retain the parts with the ribbon-guide Z in its raised position in order to free the hand of the operator, while upon returning the lever Zto its vertical position the parts will resume their normal positions aided by a coiled spring I, connected with the link L and a fixed part of the machine. The operator can also, by partially raising the ribbon-guide Z obtain a momentary glance at the writing at the printing-point during the progress of the work, in order to satisfy himself of the correctness of the last few letters printed.
According to the fifth part of the present invention, in order to adjust and regulate the length of the connecting-rods between the key-levers and the type-levers,the type-levers g at their upper ends normally rest against a padded shield 9*, arranged in the arc of a circle, as is well understood, while at their lower or cranked ends they are pivotally connected at g' with the upper ends of connectin g-rods g the lower ends of which are tapped with a screw-thread 9 Upon the inner end of each key-lever 7c is pivotally mounted at g a link 9 which is drilled wit-l1 a plain vertical hole 9 from the upper end downward for a considerable distance, as indicated by the dotted lines in Fig. 22, so as to loosely receive the lower tapped ends 9. of one of the connecting-rods g while a slot 9 is formed in the link 9 intersecting the vertical hole g, and in which works a many-sided or milled nut g which engages the threaded end g of the connecting-rod g and provides the necessary adjustment between the type-levers g and key-levers it, while at the same time the rigidity of the connection between the key-levers and type-levers is insured.
As a further security against accidental movement of the parts a jam-nut g is 01m ployed, which works upon the threaded end g of the connecting-rod g and takes an abutment against the upper end of the link g According to the sixth part of the present invention, and as represented more particularly at Figs. 30 to 34:, the transverse bars d of the lower carriage, in lieu of being formed of solid metal, as hereinbefore shown and described, are according to this modification formed of sheet metal stamped into a trough shape, as represented more particularly at Figs. 30, 31, and 32, or such bars might be of lVl-section, as hereinafter described, with respect to the longitudinal bars d, or they might be of other suitable hollow section adapted to be stamped to the required shape, by which means a bar of great stiffness is obtained at a nominal cost. In the same manner the end plates 0 of the upper carriage are formed of comparativelylight metal stamped into a dished or corrugated form in transverse section, as represented more par- IIO ticularly at Figs. 33 and Si, or they might be of other suitable hollow section, as will be readily understood.
The longitudinal bars (Z of the lower carriage, as represented more particularly at Fig. 30, are formed of an M-section, or they might be of other suitable hollow section, so as to form the grooves (Z therein, and the longitudinal bars (1 are fixed with the transverse bars (Z by means of angle brackets d and screws or rivets, as shown more particularly at Figs. 31 and 32.
In order to support and guide the upper carriage in its to-andfro movements to shift the printing-point, each end plate 0" of the upper carriage has at each extremity fixed thereto by riveting 't short horizontallygrooved bar of steel 0 in lieu of the aperture hereinbefore shown and described with re spect to Figs. 15, 1G, and 17, and the end transverse girders (7 have riveted thereto cor responding grooved bars (1", similar to those shown and described with respect to Figs. 15, 16, and 1.7.
By the arrangement of parts lastly hereinbefore described the construction of the carriage is much eheapencd, and it is rendered more rigid and reliable and of less deadweight than heretofore.
Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A type-writing machine comprising a support for the paper-carriage consisting of girders formed with lugs thereon in combina tion with a base formed with posts thereon slotted to receive the lugs of the girders substantially as herein shown and described and for the purpose stated.
