SPECIFICATION forming part of Letters Patent No. 369,401, dated September 6, 1887.
Anplication filed Decemberl, 1886. Serial No. 923,118.
(No model.) Patented in France June 9, 185, No. 169,438; in Belgium December 1l. 1885, No. 71,188,- in England Dccemberl, 1885, No. 15,4l7, and in Germany December 1l), 1885, No. 36,145.
.To (all whom, it may concern:
Bo it known that I, Tunernrnn ERNEST Entriimmnr, a citizen of the French Republic, residing at Paris, France, have invented certain new and useful Improvements in Type XVI-itin g Machines, (for which I have obtained a patent in France, dated J une 9, 1885, No. 169,438, in Belgium, December 11, 1885, No. 71,188; in Germany, December 19, 1885, No. 36,145, and in England December 15, 1885, No. 15,411.) of which the following is a speciiication.
Referring to the drawings, Figure 1 is a top plan view of my improved type writer. Figs. 2 and 3 are sections thereof, taken, respectively, on lines .fr and y y of Fig. l. Fig. 4 is a top plan view of the type carrier or wheel, showA ing the arrangement of the inkingrolls; and Fig. 5 is a vertical axial section thereof and its connection with the manipulating lever. Fig. G is a front view ofthe lever for holding thc papcrcarriage against lateral movement, showing the pivotcd tooth or dog in the position it assumes when engaging the teeth of the rack-bar on the papercarriage. Fig. 7 is a like View showing the pivoted dog in the psition it assumes when disengaged from the teeth oi' the rack-bar aud the rigid toot-h on the lever 'is engaged with said rack-bar. Fig.
8 is an elevation of the lever and its teeth, taken from the side opposite to that shown in Fig. 2, said'Figs. 6, 7, and 8 being drawn on an enlarged scale.
Thisinvention relates to typewriters, and
has for its obj ect to provide an instrument of this class simple in construction, easy of manipulation, and capable of doing all the work now done on the complicated machines ofthis class now in use.
The invention has for its further object to provide means whereby the let-ters and characters may be readily changed from one style to another, or from those used in one language to those used in another; and it consists in the general construction and combination of the mechanism by which the desired results are obtained, and in certain details of construction and combination of parts, substantially as hereinafter fully described, and as set o forth in the claims.
In the drawings, A indicates the inclosingcasing, the bottom A of which is detachably secured to the vert-ical walls by means of screws a3. In the top A2 of the box is a longitudinal slot, of', that extends practically the full length of said box from right to left along the rear wall, a, which is preferably higher than the front wall, c4, so as to cause the top to incline like that of an ordinary desk.
Although the top may be perfectly dat, I prefer to give ita certain inclination in order to afford a better view ofthe devices thereon,
and also to facilitate the operation of writing. In the top is formed an opening equidistant from the end walls of the machine, which opening extends from the front wall, at, into the slot a2, said opening being normally closed by a lid, A', hinged to the front wall at a.
The top Agand the movable portion or lid A thereof are pro vided along` the front edge of the slot al with graduations a, cach of which indientes a letter-space, the said graduations cxtending from leftto right the required distance. To the bottom Al, i inmediately below the slot a2, are secured two rails, B B, the inner faces of which have a V- shaped recess and form a guidetrack for the correspondinglyshaped carrier-wheels c of a carriage, C. In practice I mount the opposite wheels of the carrier on spring-bearings (not shown) to better maintain their position on the track and compensate for any wear of `the parts, as well as to obtain a yielding frictional contact between t-he wheels and rails.
The carriage Gis composed of a truck or platform, C', on which the wheels c are mounted, and of two end walls, C?, in which is mounted a rubber roll, D, which constitutes the impression-cylinder or platen. Upon the right end of the shaft rl of the roll D is secured a ratchetwheel, D', (shown in dotted lines in Fig. 2 and in full lines in Fig. 3,) the space between two of the teeth of which wheel is equal to the space between two lines to be written.
The spaeingratchet is operated by a pawl, E', connected with a lever, E, Figs. 2 and 3, that projects through the slot a2 in the top of casing A and terminates in a thumb-piece, e, by means of which the lever is manipulated ICO to operate the pawl, and by means of which the carriage is moved back into position for commencing a new line.
The ratchet-wheel has a series of holes, d', one for each tooth, with which engages a stoppin, d, on the end of a spring-lever, Dz. The paper upon which the writing is done is inserted between the roll D anda guide, F, of sheet metal,that has alongitudinal slot, f, facing the type-wheel and line of typethereon, the guide being suitably supported between the end walls of the carriage..
It is obvious that when the roll D is rotated a distance equal to that between two of its teeth the paper will be moved with it a corresponding distance, the spring-lever yielding to the power applied to the spacingwheel D', disengaging the same and springing back into the next hole, fZ, as it moves in line therewith. rlhe carriage is actuated by means of a coiled spring, G, one end of which is secured to said carriage and the other to the left end wall of the easing, as shown in Fig. 3.
To the hinged portion A of the top A2- of the inclosing-casing is secured adisk,K, which is fitted over an opening, a, formed in said hinged portion A. The disk has an annular flange, K', of such diameter as to leave a space, 7c, between it and the periphery of said disk, in which space are marked the letters,numbers, and other characters the machine is adapted to print, the flange K being provided with a series of` vertical slots, k', corresponding with the series of letters, Snc., on the annular space le. The disk K has a hub, K2, in which fits a corresponding hub, w, projecting from a type carrier or wheel, W, which is rigidly connected with a lever, L, for positioning the wheel by means of a fianged sleeve, M, the flange m of which rests loosely on the disk K, and by means of keys or set-screws m', as shown in Fig. 2, the lever L is pivoted at Z between the arms Z Z', that project fromabase-plate, L', and said base-plate is secured to the flange m of the sleeve M by the screws m', which also lock the hub w to said sleeve.
It is obvious that when the lever L is lifted out of the slots 7c' in ange K and turned around to rotate the sleeve M the type carrier or wheel will be correspondingly rotated, and if the type on the carrier are properly arranged relatively to the characters on the disk K it is obvious that said carrier may be positioned to bring any desired character opposite the slot f in the guide and guard F by moving4 the lever L to the corresponding character on the disk K. By depressing the lever into a slot, 7c', in flange K the typeAwheel lV is locked into position. The typewheel has a periph* eral recess, w', in which is sprung an endless type-band, N, of rubber, on which the characters are formed in relief, and said wheel has a vertical slot, 102, in its periphery in rear of each character.
O is a push bar or bolt that is fitted loosely in the sleeve M,and projects through the plate L of the support ofthe lever L, which latter rests upon said bolt. The bolt projects through the type-wheel W and bears upon the arm P' of an angle-lever, P, controlled by a spring, S, in such a manner as to lift the bolt and lever L when relieved of pressure. It will be seen that by this arrangement whenever the lever L is depressed into one of the slots k and again released the spring S, acting upon the leverarm P', will lift the bolt O, and through the latter the lever L, out of the slot again, this being the normal position of the parts described.
To the arm P2 of lever P is pivoted one end of a presser-bar or follower, Q, that acts to press the band forward and print a character on the paper on roll D. The forward or free end of the bar Q, entering one of the slots wz in. the periphery of the type-carrier W, behind one of the characters on the type-band N, pushes said character out through the slot f of the guard or guide F onto the sheet of paper whenever the lever P is depressed by the lever L.
The forward end of the bar Q is supported from and guided in the upper forked or slotted end of the standard I.
The step-by-step movement of the paper carriage during the operation of writing is effected in the following manner:
H indicates a lever pivoted at 7b2 upon the standard I, the rear arm of which lever projects into the path of a pawl or catch, p', hinged to the outer end of the arm P of lever P in such a manner as to yield or swing upward against the stress of a spring, p, to clear the rear end of lever H without operating the same when the arm P of lever P is swung downward to actuate the bar Q, but to engage the rear end of lever H to swing the latter on its pivot when said arm P is moving upward. rlhe lever H at its forward end is provided with a rigid tooth or dog, 2, and a tooth or dog, 1, pivoted below tooth 2. When notengaged with the teeth of the rack-bar' on the paper-carriage, the tooth 1 stands in advance of tooth .f-that is to say, it will stand in a different vertical plane from that of tooth 2,
as shown in Fig. 7-a spring, h5, secured at one end to the lever H and bearing at its other end upon the rear portion of tooth 1, causing the latter to assume said position. When, however, the tooth 1 is' engaged with the teeth of the rack-bar, it will, under the stress of spring G, acting upon the paper-car riage, be moved directly beneath the tooth 2,
as shown in Fig. 6, astop-pin lying in the path of tooth 1, or a squared shoulder formed on the rear thereof, holding the same against any farther horizontal movement upon its pivot in that direction, thereby holding the paper-carriage stationary. Vhen the machine is at rest, or during the time a character is being printed, the tooth 1 lies between two teeth of the rackbar C3 on the paperearriage,holdng the latter stationary, the tooth 2 at the same time lying directly above tooth 1. v When a character has been printed ,the lever P, under the stress of its IOO IIO
spring S, will rise, the nose p2 of arm P engaging the rear end of lever H', and tilting the latter upon its pivot. As the forward end of lever H is depressed, it will tend to carry tooth l from between the teeth of the rack-bar; but before said tooth clears the same the tooth 2 will enter the same interval occupied by tooth l, and as soon as tooth 1 clears the rackbar it will, by reason or" the spring h5 pressing upon its rear end, be sprung out into a position immediately below the next interval on the rack-bar, as shown in Fig. 7. rlhe arm p on lever P will now clear the rear end of lever H', and the latter, under the action of spring IL', will be tilted, the forward end of said lever rising, which will cause the tooth l to enter that interval on the rack-bar beneath which it stands, and causing the tooth 2 to pass upward clear of the teeth of the raclebar, and as soon as said tooth 2 clears the rack-bar the carriage will, under the stress oi' spring C, be moved a letter-space to the left-that is to say, until the tooth 1, which now lies between two raelrbar teeth, moves into position beneath tooth 2-where, by reason of the stop-pin employed or the shoulder formed thereon, it will be arrested in its movement, and the carriage will therefore be held against farther movemont until after the next depression of lever L, when the described operation will be repeated, the carriage being thus fed forward step by step after each depression of said lever L. When it is desired to return the carriage to the position for printing a new line,this can be done by means of the lever E, the tooth l of lever H', which is in engagement with the rackbar on said carriage,yielding laterally to permit the latter to be moved back, after which said tooth will be again forced into engagement with the rack-bar teeth by means of the spring 71.5, which then bears upon the forward end of the tooth.
At the left hand of the inclosing-case and secured to the top A2 thereof is arranged a bell, R, the arm ot' whose hammer It projects into the path cfa lug, ci, Fig. 3, on the left of carriage C, above which lug is arranged a pointer, c, that travels with the carriage along the gradnations ai. By means ot' this pointer the positioning of the carriage C relatively to thc point at which the printing is commenced for each line may be indicated on the gradua tions ce, and said pointer will also indicate when a line is completed, irrespective of the bell R, if proper note is taken. In practice I employ, besides the usual pointer and bell, movable stops t, to limit the traversing motion of the carriage in either direction, said stops being adjusted along the graduations and proj ect-ing into the path of the pointer 0*. T T, Fig. 4., are inking-rolls suspended from the hinged port-ion A of the top A2 of the case A on opposite sides of the type-wheel lV, and in proximity to the point where the impressions are made on the paper.
It will be observed that on the disk K there is a space devoid of characters, the type-band having a corresponding empty space. Vhen the lever L and the type-wheel W are rotated to bring this space in proper position, said lever may be depressed any desired number of times without making an impression, so that any desired space may be obtained between two words.
From the description of the construction, arrangement, and operation of the several parts that constitute my improved type-writer its operation will be readily understood by al1 those eonversant with this class of machines, and this operation need therefore not be further described. The inclosing of the operating mechanism within a casing preserves the same from dust and dirt, and therefore does not require the attention necessary in that class of type-writers in which the entire operating mechanism is exposed.
The object in hinging that portion A ofthe top A2 ot' the inclosingcase A is to provide means whereby easy access may be had to the carriage and the mechanism contained in the case, as itis obvious that by swinging the portion A open the type-wheel W' and pushpin O are swung out ofthe casing, leaving the remaining mechanism exposed.
By connecting the bottom Aa of the inclosing-case A detachably to the vertical walls thereof said bottom, to which a portion of the operating devices are secured and on which the carriage travels, may be readily taken out and access had to any part of the machine.
I have described above the use of an elastic type-band. It is Vobvious that by means of this arrangement the style of letters may be readily changed by substituting one typeband for another and writings obtained in any desired language by simply swinging out the typeovheel NV, removing the type'band N thereon, and substituting another having the characters, rbc., ofthe language in which the printing is to be effected.
The construction of many of the operative devices may be varied without departing from the nature of the invention. For instance, the lever L may be provided with a downwardlyprojecting pin adapted to engage holes in the disk K. The push pin or bar O may, if desired, be pivoted to said lever and to the lever I?. A springstop may be employed and arranged to engage the teeth ot' the spacingratchet D', instead ot' a pin entering a hole in said ratchet. The carriage may be mounted so ai to slide on the rails by atongueand-groove joint. Instead of an impression-cylinder, D, performing the function of a platen, a platen may be employed in conjunction therewith of suitable rolls for moving the paper thereon to space the lines, the sleeve M may bc dispensed with, and the plate or disk L of lever L secured directly to the' hub w of the typecarrier WV by means of a key, or said plate may be provided with a screw threaded socket to screw in or on the hub ofthe type-wheel.
