ERNST VILHELM BRACKELSBERG, OF HAGEN, PRUSSIA, GERMANY.
SPECIFICATION forming part of Letters Patent No. 335,887, dated February 9,1886.
Application filed October 19, 1885. Serial No. 180,327. (No model.) Patented in Germany December 16, 1884, No. 31,985; in Belgium February 20, 1885, No. 67,945; in France February 21, 1885, No. 167,205; in England February 27, 1885, No. 2,688, and in Austria` Hungary June 27,1885, XXXV, 1,116, and XIX, 1,114.
To all whom t may concern:
Be it known that I, ERNST WILHELM BRACK- ELSBERG, a subject of the King of Prussia, and residing at Hagen, Westphalia, Kingdom of Prussia, German Empire, gentleman, have invented a new and useful Improved Type- Writer, also applicable for stamping matrices, (patented in Germany December 16, 1884.,` No. 31,985; Belgium, February 20,1885,No.67,945; France, February 21` 1885, No. 167,205; Great Britain, February 27, 1885, No. 2,688, and Austria-Hungary June 27, 1885, respectively Tom. XXXV, fol. 1,116, and Tom. XIX, fol. 1,114,) of which the following isa specification.
My invention relates t apparatuses known under the name of type-writers; and it con` sists in the means employed for printing or impressing letters or other characters in succession upon a sheet of paper or other material, for causing the spaces between the letters or characters composing a word to become uniform, and for regulating the width of these spaces, as hereinafter described and claimed.
The improved apparatus is represented on the annexed six sheets of drawings.
Figure 1 (divided into Figs. 1a and 1) is a front view ofthe same; Fig.2, (likewise divided into Figs. 2a and 2",) a plan; Fig. 3, a trans verse section on line z e, Fig. 1, looking from the left to the right. Fig. iis afront View of a portion of the apparatus, `in which some parts have been omitted in order to show others more clearly. Fig. 5 is a bottom view corresponding to Fig'. 4. Fig. 6 shows a section on line y y, Fig. 4. Fig. 7 is an enlarged portion of Fig. 5, serving to explain the operation of certain parts. Fig. 8 is a front view, and Fig. 9 a transverse section, of a modified part of the apparatus adapted to produce matrices for stereotyping. ber of equivalents of certain parts.
The types are secured in a single row to the holder T, which is connected by the pieces a to the stationary guide-bar a, so that it can slide thereon. 1f preferred, the holder and the types may, however, be made in one piece. The said type-holder is operated by the rod b, exibly attached to an arm of the former by Fig. 10 shows a num-- means of a balland-soeket joint, b, or other equivalent means, and carrying at its other end a handle, c, terminating in a beak, e2. Close to the bar a there isa lever, e, having its fulcrum at e', and kept normally in a raisedposition by a spring, e2, the saidlever being movable in a plane parallel to the body of the types. To the lever e are attached ledges d, carrying a register ofthe characters of the types contained in the type-holder, and these characters are so arranged in respect to the types, and the length of the rod b is such that when the beak c is placed upon one of the characters of the reg ister the type corresponding thereto will be brought opposite to the end of the printingbar D, serving to press the paper against the type.
v For the purpose of guiding the operator in placing the beak c2 on a character, so that the type may always be brought exactly into the required position,special means are provided. By preference these consist in plates d', having opposite to each character a triangular notch, di, the inclined faces cl3 whereof will conduct the beak c2, provided with a knifeedge,to the proper point,if it should not have been placed thereon at once. The characters of the register are distributed upon two or more ledges, d, in order to allow each notch to be made of such Width as that the liability to commit errors While inserting vthe beak c2 will be reduced as much as possible. The operation of bringing the beak cJ to appropriate place is further facilitated by the fact that the ledges d, together with the notched plates d', are arranged at different elevations, or in lines which slant or incline upwardly as they depart from the pivot e', as seen in Fig. 1, each following one being placed higher than the preceding.
The form of the notches di may be made different from the drawingsfprovided their sides d3 converge downward, so that the beak c2 will not shift laterally after having been pressed down Within the notch. (See Fig. 10, I.) Moreover, the notches may be replaced by conical holes in the plates d, Fig. 10,11, the beak c2 being in this case made in form of a round pin directed downward also, a beak forming a triangular prism, or a cone may be used, respectively,with notches or holes having such form that the inclined sides ZZ of the said prism or cone will come in contact with the upper edges thereof only, Fig. 10,111 and 1V; o r the arrangement is inverted by attaching projections, pins, prisms, or cones to the register, and forming the beak with a triangu lar notch or a hollow cone, or with a notch or ahole adapted to the said prisms or cones, Fig. 10, Vto V111, the object being in every case to conduct the beak c2, by the agency of two inclined surfaces,d3,into the desired position.. These surfaces di, 1 shall call guides The printing-bar D, which is movable in a direction vertical to the face of the types, is connected to the lever e by means of the lever 1 and the rod 7c, so that when the lever e is depressed the printing-bar will be raisedy and press the paper W, Fig. 3, which is above it, against the type. The depression of thelever e Ais brought about by a pressure exercised on the same by means of the handle c and beak c2 subsequent to the insertion of the latter into a notch. The handle c is provided with a plate, c', forlaying on the forenger while performing this operation. By these means a print of any single type may be obtained.
The sheet ofpaper W which is to be printed upon is held by a carriage, H, arranged to slide lengthwise upon the tablef of the apparatus, and which, when this table is inclined, as shown in Fig. 3, may be guided with sudicient security by a single ledge in front of it; but other guiding means may be employed..
The said carriage consists of a bottom plate, two standards at the ends thereof, and a bar, h,connecting the standards at the top and par allel to the bottom plate. In the said stand ards is mounted a roller, g, portions of which are faced with india-rubber, by means whereof the roller bears upon the sheet of paper slipped under the same. One of the pivots of the roller carries a ratchet-wheel, j, with which gears a pawl arranged to be operated by a handle, t', for the purpose of turning the roller, and thereby drawing the paper forward through the medium of the india-rubber facings .when a newline is to be commenced.
The carriage H, with the paper upon it, is moved toward the left for every letter or character to be printed, or for every space required, by the following mechanism: To the aforesaid rod la is connected, by means of a link, Z, one arm of an elbow-lever, Z', having at the end of its other arm a pin, Z2, engaging in a slit, Z3, at the end of a bar, m, which for the present may be supposed to-be rigidly xed to a bar, m. This bar m is connected by a curved link, m2, to a rod, n', suspended with a slit, at, on a pin, n, screwed into an upright arm, es, of the lever c, the said rod n being drawn downward and against the pin n by a spring, as, iiXed with one end to n, and with the other to a knob at the head vof u. Finally, a. bar, G, is pivoted with one end on the pin a2, connecting the parts n and m2, while with its other end, which is bent obliquely to the bar h of the carriage H, and which has a suitable aperture, it embraces the said bar h in such a manner that when the pin n2 is depressed the bar G will pinch the bar 7i, and thus become locked with the carriage, whereas so long as the pin a2 is in its raised or normal position the bars G and h are independent of each other.
The operation ofthis mechanism is as follows: When the levere is depressed,it draws,through its arm e, the pin n, and the spring n3, upon the rod a', which, in acting on the bar G, causes the same to become locked with the carriage H. Meanwhile the pin Z2 of the elbow-lever Z slides in the lslit Z3 without acting; but 4when Zl strikes against the left hand end sur-- face of the slit Z3 it pushes the united bars m and m to the left, and this motion is transmitted, through the connecting-link m2,to the bar G, which, being locked with the bar h, draws the carriage H with the sheet of paper to the left, so that afresh portion of the lat-ter will be presented to a type. The bar G thus acts as a silent feed pawl. Thereafter the printing-bar D presses the paper W (on which a sheet of paper covered with printing-ink is placed, as usual) against the type above it. During the latter part of the downward motion of the lever e the spring n3 expands, under the strain brought to bear upon it after the pawl G has pinched the bar h, and thus allows` the lever e, together with the pin a, (which then slides in the slit n* of the rod n,) to be completely depressed, while the pressure on G re'mains nearly uniform.
I shall now proceed to show by what means the displacement of the paper-carriage is regulated and the blank spaces between all the-l For . o, fixed to the bar m', the said gage-lever being pressed with its lefthand curved beak o2 toward the types and the recesses p by means of a spring, o', while on its right-hand end acts a curved iinger, o3, Figs. l, 4, 5, and 6, fixed to the lever e, so that when the lever e is in its raised position the finger 'o3 will keep the gagelever M out of contact with the types, whereas when e is depressed the said finger allows the spring o to press the gage-lever, with its beak 02, against the type, or into the IOO IOS
recess opposite to the said beak; thirdly, the
bar m is connected to the bar m by a pin, ma, screwed into barm through a slit, m6, in bar m, and by a spring, m5, attached with one end to a projection, m, on bar m,and with its other end to the pin ma, this spring tending to draw the bar m, with the left-hand end of its slit m6,
against the pin m3,- '1"ou`rthly, the notches d, or their equivalents, are so adjusted that when the beak c2 is inserted into any one of them the corresponding type will be brought with its right-hand edge into a certain denite position-say in a line with the right-hand surface ofthe printing-bar D, as shown by a dottedline in Fig. 7. Suppose this type to be the one for the letter nl and the type following to the left to have the letter s77 ou its face. As has been stated, the bars m and m begin to move to the left,4 under the pressure of the pin ZQaiter the carriage H and the pawl G have become locked together, and this condition is not altered by the introduction of the spring nr", which is made strong enough to overcome the frictional resistauces ofthe parts m, m2, u', G, and H. About at the same time that pin Z2 begins to act ou m the finger o3 has released the gage-lever M, and the spring o has pressed it with the side of its beak 02 against the type, being then in proper position for printing-t'. e., in the present case against the type for m. The bars m and m thereupon moving forward,together with the gage-lever, cause the beak o2 ot' the latter to slide across the type for m7 and into therccess between the same and the type for s As soon as the beak o2 strikes with its tip against this type, the motion of the gage-lever,and consequently that of the parts m, m2, and G, and of the papercarriage, is stopped. The bar m may, however, continue to move forward, as its elastic connection with the bar m by means of the spring m5 allows it to do so. This arrangement is required in order that the lever c may be completely depressed and the printing-bar brought to bear against the type after the bar m' and the paper-carriage have been stopped.
The ei'iect which the described operation of parts has on the spacing of the letters on the paper may best be explained by aid of Fig. 7, which shows to an enlarged scale, and from below,a portion of the type-holder T with the beak 02 of the gage-lever in two dili'erent positions. Supposing that while the beak o`Z is in its normal position (drawn in full lines) a point, w, be marked thereon opposite to the right-hand edge of the type for m1, and assuming, moreover, that a be the distance of the point w from the tip ot' the beak 02, x the width of the type opposite to the beak, and v the uniform width ofthe spacing-pieces p, (or of the recesses p,) it will be apparent from the figure that the stroke of the beak is equal to x-l-v-za or, expressed in words, that it is equal to the varying width of the types, plus the space o minus the length u; therefore so long as a remains unvaried the spaces between the letters printed on the paper will be uniform and equal to l1-u.
Then the lever e is released so that it will be raised by the spring e2, it lirst causes the printing-bar D to be withdrawn from the type, and at the same time it allows the bar m, irnpelled by the spring nrgto follow the pin ZZ as it recedes, and with which m is in contact by the left-hand end of slit Z3. Simultaneously the piu u in rising allows the spring aito coutract, and thereupon raises the rod a, whereby the feed-pawl G is iirst relieved ofpressure and then positively raised with its outer end, so that the paper carriage becomes disengaged from G. Moreover, the fiugeroi, acting on lever M, withdraws the beak oof the same from the types. Vhen thereafter the left-hand end of slit m has come into contact with pin mi, the bar m', gage-lever M, link m?, and feedpawl G move to the right, together with bar m, until m strikes against a stop, t. The papercarriage meanwhile remains at rest, as the pawl G is freev to slide on h. During the tinal part of the motion of e the pin Z'z moves along the slit Z3 to its right-hand end. The apparatus is then ready for renewed action.
In the 'foregoing it was stated that the spaces between the letters printed on the paper will be uniform solongl as the dimension a remains unvaried. The said dimension may, however, be varied, and the spaces between the letters thereby caused to become wider or narrower, as the case may be. This is attained by making the aforesaid stop t adjustable. In the drawings it is supposed to consist in an eccentric segment pivoted to the frame of the apparatus and provided with a handle for turning it. In the measure as this stopis adjusted so as to allow the beak o2 to recede more or less the aforesaid dimension a will be altered. Vords to be rendered conspicuous may thus be printed with wide spaces between Ithe letters.
After a line has been tinished the carriage H is moved back by hand up to an adjustable stop, f. Besides, the paper is shifted forward as much as is required for the height of a line by means of the handle rZ, operating the ratchet-wheelj.
In order to inform the operator when a liuc is iuished, there is liked to the tablef a bell, r, on which strikes a hammer, s, attached to one end of a lever, s, bearing with its other end against the carriage H and arranged to be released at the proper moment.
The apparatus as described may be employed without alteration for producing Inatrices for stereotyping, it being only required for this purpose to replace the paper WV by a sheet ot' sot't pasteboard or other material adapted to receive and retain sufticieutly-deep impressions,and as is otherwise used for makingV matrices. I prefer, however, in this case to adopt the modified arrangement represented by Figs. 8 and 9, in which the types T are mounted movably in the type-holder T,while the matrice-blank is supported by a stationary block, U.
ward against the blank by an arm, D, attached to the lever e, and they are raised and maintained in their normal position by means of springs, such as shown in the drawings.
The types are pressed down- I For shifting the blank n the direction of the height of the lines, two rollers, g and g, may be employed.
I claim as my invention- .,1. The sliding type-carrier T, with types, the rod b, flexibly connected thereto and provided with beak c2, the lever e, carrying a register of the characters of the typeaarranged to correspond with the types, as described, guides d, for guiding the beak c2 in respect to the characters on lever e, land means, substantially as described, in connection with c, for producing contact between the type being in printing position and the material to be printed upon, all combined and co-operating substantially as specified.
