CHARLES SPIRO, OF NEV YORK, N. Y.
SPECXFICATION forming part of Letters Patent No. 435,775, dated September 2, 1890.
Application filed March 8, 1889. Serial No. 302,419. (No model.) Patented in England March 22, 1889, No. 5,002, 4and in France April 30,1889,Nc.197,856.
To @ZZ whom iv' may concern:
Be it known that l, CHARLES SPIRO, a citizen of the United States, residing at New York, in the county of N ew York and State of New York, have invented certain new and useful Improvements in 'lype-'lVi-iting llaehines, (for which l have obtained patents in foreign countries as follows: In Great Britain, No. 5,002, dated March 22, 1880; in France, No. 107,850, April 30, 1880, and for which l have application pending in Germany of which the following` is a specification, reference being had therein to the accompanying drawings.
My invention has relation to certain improvements in that form ot' type-writer in which the writing is visible to the operator as the work progresses, and in which the typebars are thrown downward into contact with the paper.
The main features of this machine have been described and claimed by me in applications l'or Letters Patent now pending before the Patent Oflice, and numbered as follows: Serial Nos. 210,(58t and 283,080, and patents No. 400.265,(lated )viareh 20,1880; No. 400,710, dated April 2, 1389, and No. 22018, dated February 25, 1000.
In the d ra\\'ings,lf`igure 1 is a central transverse vertical section of my type-writer. Fig. 2 shows the paper-carriage in full, the base ofthe machine being shown in vertical section lengthwise ol' the carriage and the barlock being removed. Fig. is a plan of the rear portion ot my machine, showing a portion of the carriage broken away, as also a portion ot' the spring-shield. Figlis an end View oll the carriage ot' my machine, with the spacing-lever and the pawl-relcasing mechanism removed, certain details of the linespacing and paper-holding mechanism being shown, as hereinafter described. Fig. 5 is a perspective of my letter-spacing pawls. Fig. o' is a plan ol". the yielding pin and teeth, which hold the feed-ratchet mechanism for the inking-ribbons in place. Fig. 7 is a central vertical scction ol' my bell and inner sleeve, adapted to be used as a revolving knob for the roller. Fig. S exhibits the details of the attachment ot the upright keys to the keylevers. Fig. 0 is a side elevation of the titting of the type-bars into the brackets. Fig. 10 is a longitudinal vertical section of said fitting, showing the ball-and-soeket attachment of the type-bar to its bracket. Fig. 1l is a perspective of my bar-lock and turningpin for thehiking-ribbon. Fig. 2 is a detail in bottom plan. Fig. lil is a sectional view of aportionof the under side of the carriage. Fig. 1l isa perspective view of the main pawl removed and divested of its secondary pawl and (3o-operating elements.
A is the base of my machine, which is mounted upon legs lS, preferably provided with feet of rubber to avoid scratching and noise. Running across this base from right to left is the rear partition C. Projecting backward from this partition are the pins O, from which depend springs O2, which are protected from dust by the rear shield O3, preferably fastened to the partition and curving backward. A pivot-rod extends from One side of the base to the other, and underneath the same at D. The key-levers E are indented orcutoutat thispoint te fit this rod, as shown in Fig. l. 'lhese key-levers are attached to the springs C2 at the points Ct, and are thus held up against the rib F and therod l). The tension ot' these springs is constant, and just sufficient to keep the key-levers always in place. Depending from the rib F are a num` ber otpins F, intended to guide the key-levers during the rise and fall to which they are subjected.
The keys proper are attached to the keylevers as follows, and as shown in Fig. S: 'lwo grooves E3 are cut across the end ot each keystem, leaving a boss more or less square in shape. A hole is eut through the key-lever, fitting' this boss, and the latter is projected through this hole, as shown in the left-hand portion ol Fig. S at E2. rlhis boss is then riveted over and the stem thus thoroughly secured to the lever. lly this means there is no possibility ot wabbling or wear between the stem and the lever.
Standing upon the base are the brackets G, one on each side of said base. To the top of these brackets is secured the perforated curved platform G', around the edge of which is secured the upwardly-projecting shield G2, intended to serve as aprotection for the typebars, as well as an abutment for the same. On this platform are set two rows of brackets G3, one behind the other, as shown. Between these two rows is arow of perforations G4, serving to admit of the passage of the depressing links r5, leading to the type-bars set in the rear row of brackets. The type-bars are set into these brackets, as shown in Figs. 9 and l0. In these figures G6 are upright extensions rising from the front ends of the brackets In the inner face of these extensions are cut, ground, orotherwise formed the curved seats G7, preferably forming a segment of a sphere. Goincident with one of the radii of the sphere and perpendicular to the two sides of the extension G6 are two perforations G8, one of the same being screw-threaded. Through these perforations the bolt G10 eX- tends, and is screwed in with the tightness desired. Mounted a trifle loosely upon this bolt as a pivot and situated between the two sides of the bracket is a sleeve secured to or forming a part of the type-bar I-I and shown at G9 in the ligure. This sleeve has its two sides ground or otherwise made to it the seats G7 in the side extensions. In the direction of the length of the type-bar this sleeve does not completely lill the seats, but a slight space is left, as shown. The object of this inode of mounting of the type-bars is to present a continuous bearing in any alignment of a type-bar and to allow for wear at the bearings. This seating prevents all twisting of the type out of the true perpendicular to the paper at the printing-point that is likely to occur, and is indeed almost inevitable in the case of conical seatings, as there is no chance for side movement in the type-bars or in the conical sleeves, th us causinga side tilt of the types and a consequent irregularity of presentation of the surfaces of the same to the paper and partial printing of the characters. Vhen any such wear occurs with my form of seat the spherical surfaces of the sleeve are free to move evenly over the seats in the bracket without such tilt, and thus this difficulty is avoided and uniformity of wear induced.
My type-bars lie back normally against the back of the shield G2, against a point II', provided with padding in` order to obviate all noise on the return of the types to their normal position. This padding exten ds in a strip around the whole length of the row of types, and the t ype-bars in both rows of brackets lie against the same.
Forward of the sleeve G9 in each type-bar there is provided a perforation H2, in which is fastened the end of the link G5 for depressing the bars. The other end of this link is hooked into a screw-eye H2, which is screwed into a nut 114 seated in the key-lever.
In front of the type-bar platform there isa bracket I, mounted on the top of the base. On the top of this bracket there projects a bar-lock of the character shown in Fig. 11 over the printing-point. This consists of a plate I having a concave semicircular front edge, along which is placed a row of upwardly extending teeth I2, just far enough apart to admit of the interposition of one of the typebars for the purpose of locking said bar and guiding the same to the exact printing-point, vas described and claimed in my Letters Patent No. 400,265.
A turning-pin I3 projects sidewise from an arm I4, projecting at one end of the plate I.
This pin has a notch in it for the purpose of marking the printing-point for the information of the operator, and serves for the support of the inking-ribbon, as hereinafter described. This plate is fastened to the top of the bracket I by means of a perforation I5, and is further held from rotation thereon by means of the pins I6, which are adapted to enter holes provided therefor in the top of said bracket.
Projecting downward through the body of the bracket is a swivel-bar I7, at the bottom of which is a throwing-piece I8, similar to that shown in my application for Letters Patent, Serial No. 272,565. Let into the depression in the base of the bracket I is a yielding pin I9 in the same plane with the throwing-piece I8. Behind this pin and at the bottom of the recess is a spring Ilo, which tends to keep said pin constantly in contact with the edge of the throwing-piece.A This edge is provided with two notches I, and the end of the pin is shaped to enter these latter, as shown in the figure. On the two ears of the throwingpiece there are upright pins 112, for the same purpose as those on the throwing-piece on my device described in my application, Serial No. 272,565, as will be further described. By turning the handle on the top of the swivel-barl7 the throwing-piece may be thrown from .one side to the other, and the notches Iu on one or the otherside of the same be brought into engagement with the pin I9 to hold the throwing-piece firmly in position.
On the sides of the. bracket I are pivoted the spools K, carrying the inkingribbon, which extends from the one around and over the turning-piu I3 and back to the other spool, as shown and described in my application, Serial No. 272,565.
Under the whole length of the key-lever space there extends a bail L, which is preferably connected by three arms with the pivotbar or rock-shaft L', Fig. 1. Rigidly attached to this pivot`bar and extending upward are the two stems L2 and M, the former being pivoted to the inking-ribbon feed-pawl L2 and the latter being the carriage feed-pawl stem. L3 is of the same form and performs the same function as the similarly-placed pawl in my application, Serial No. 272,565--namely, to turn the inking-ribbon spools alternately, according as to whether the swivel-bar is turned in one di- IOO IIO
rection or the other, and the pins 112 brought into contact with the back of one or the other side of the double feed-pawl L3. This pawlstem being pivoted between the two spools and said spools being provided with ratehetwh-ecls, as described in my application, Serial' This last beine` in contact with the teeth of the ratchet, causes the spool to make a portion of a revolution, and the springs L, which are situated just behind the edges of the pawl, engage with the teeth of the spools and prevent their return against the feed.
The stem M carries the carriage feed-pawls, and is best shown in Fig. 5. This stem is cut out, as shown at M', and above the eut there is provided the main swinging pawl M2, carrying the beveled tooth M3, and turning upon the pivot M". The side ot' this pawl is cut. out, as shown, for the reception of the secondary swinging pawl Mi', turning upon the pivot M6, and carrying the tooth M7, beveled in the same direction as thc tooth M3. On the back of the pawl M2 there is placed the friction-pin MS, which nm y be replaced by a small roller, it desired, and which plays within a space cut out of the end and top of the pawl-stem. The spring-wire M. is wound around the pivot M, and tends to hold the sccondarypawl in the open position shown in the figure. The spring M1 is wound around the pivot M", and has its end attached to the pin M, tending to hold the main pawl M2 upright in the position shown in the figure. On the bottom of the main pawl M2 there are two dependingpoints UW, which are adapted to be brought into conta-ct with the pin M, when the pawl llll is swung on its pivot. The teeth of these pawls are always in diiierent planes.
Under the carriage O, and running the whole length thereof, is the rack-bar O', having depending teeth beveled to allow of the motion backward of the carriage, but having vertical faces so placed as to arrest the forward motion ot' the carriage by engagement with the teeth on the pawls of the feed mechanism. This is plainlyshown in Figs. l and 2.
There is a proj ection on the front face of the partition G, through which is inserted a screw l), on the end oi' which is inserted a spiral spring l, having' its other end fastened to the bail L, through the medium of which the tension ot' said spring is transmitted to the keylevers, and they are held up against the rib with an adjustable pressure. It is the ten sion of this one spring which holds the inking-ribbon pawl down and which holds the carriage feed-pawls in the position shown in Fig. l-that is to say, with the secondary pawl-tooth in contact with the rack on the carriage. New when the keys or the spacinglevers are depressed this spring is extended and the carriage feed-stem is tilted in such a position as to throw the main pawl-tooth into engagement with the teeth of the rack. This movement frees the secondary tooth, and the spring M9 causes the secondary pawl to tilt forward a distance equal to the space between two teeth of the rack, as shown in Fig. 2. On the release of the levers the spring P2 comes into action, the bail is lifted, and the stem tilted back again into the position shown in Fig. l. At this time the secondary pawl-tooth being caught by the next tooth in the rack, the carriage is allowed to move forward a distance of one tooth, by means hereinafter described, and the secondary tooth is brought back into its upright position upon the mainpawl body. By means of the screws M13 in the body of the main pawl the secondary pawl may be readily adjusted in its throw to the teeth of the rack-bar, and thus expensive labor in fitting the parts is avoided.
The carriage is provided with back cars Q',
which slide upon a back rod Q, held in brackets at the two ends of the machine, the forward portion of said carriage being supported by a wheel which runs on the base at Q2.
At the two ends of the carriage and under the platen are pivoted two arms N, held up by a spiral spring n. (Shown in Fig. 2.) Extending from one of these arms to the other is a wire bail resting upon the friction-pin M8 of the main pawl. On one end of the carriage there is pivoted a bell-crank N2, on the short horizontal arm of which is attached a spring N3, which projects over one of the arms N. By pressing the handle NL toward the platen the spring Ns is depressed, and with it the arm N and the bail N. This causes the depression of the pin MS and the side tilting of the main pawl M2, thus throwing the teeth upon both pawls out of gear with the rack and allowing the carriage to be moved either way without obstruction.
The motive power which actuates my machine in its feed is a spring-drum of the nature shown in my application, Serial No. 272,565, and seen in Fig. 2 at R. This drum is mounted upon a pivot which projects downward through the base of the machine, and around which there is wound a spiral spring R4 to keep the drum up and oft' of the base. Atthe bottom of the pivot is a disk R', having notches R2 at various points in its periphery intended to engage with a pin R3 projecting from the under side of the base of the machine. This is for the purpose of tightening the spring within the drum, as shown in my application, Serial No. 272,565, which is aecomplished as follows: lVhen it is desired to tighten the spring, said drum is depressed against the action of the spring R, and the disk-notch thrown out of engagement with the pin R3. The drinn in this position is IOO turned through the required arc and then allowed to rise again in such a. position as to allow of the engagement of the pin with a new notch. \Vonnd upon this drum is the cord R5, which is attached to the machine at' R6, and by which the spring within the drum draws the carriage.
A iirm projection S rises from the top of the base just.. behind the pawl-stem, and through the same there is an adj listing-screw S', which may be screwed farther from or nearer to the pawls. Against this screw the pawl is made to abut when the carriage is brought to a stand by the resistance of the tooth on the secondary pawl. By this means all the jar oi' the sudden stoppage ofthe carriage is taken off of the pawls and is transmitted directly to the body of the machine, a circumstance conducive to the increased life of the machine, and which prevents much of the noise incident to the use of a type-writer. By the adjustment of the screw the abutment may be brought to such a position as to bring the teeth in a vertical posture at the momentof abutment.. This adjustment is useful where there is a new rack to be used with a dilferent spacing of the teeth. It also lprevents diminution of speed arising through tremor of the machine.
The platen is pivoted in the ordinary manner between two brackets at the extremities of the carriage, and the axle of the same is carried out at both ends, as shown in Fig. 2. On one end there is a bell T, attached to this axle in a manner best understood by inspection of Fig. 7, where the bell is shown in section. As will be seen, there is an in wardly-projecting sleeve T2, adapted to lit tightly over the end of the axle of the roller, and in which there is a notch cut out, as at T3, for the purpose of engaging with a pin on the side of the axle. By this means the bell serves the double purpose of a knob for the more convehient turning' of the roller and a bell for warning the operator when he has come near the end of a line. plished by means of alittle gravity-bell hammer t pivotcd to the body of the carriage at t', within the bell almost, and provided with a depending point t2 pivoted thereto, so that it will only operate to lift the bell-hammer on the forward movement, and will allow the point to pass the peg, hereinafter described, on the back movement without sounding the bell.
At the other end of the roller, Fig. 4, there is a wheel mounted on the axle of the platen and having round teeth, as shown at T1. lVithin this wheel, or between it and the platen, is a pawl-carricr, pivoted also to the end of said platen-axle, as at T5, and this piece carries a pawl TS pivoted thereto and held against the teeth of the wheel T1 by the spring T1 on a link T' depending from said pawlcarrier.
Pivotcd at the extremity of t-he carriage is a bell-crank lever T9, having a point at one This warning is accom-s end T10, which fits in between two of the teeth on the Wheel T'1 and is turned at T11 in a longitudinal direction.
Pivoted to the bell-crank T11 ata point part way between the pivot of the same and the end nearest the platen is a stop-piece T12, which is adapted to be turned up, as shown, or down, so as to strike the bottom of the carriage before the bell-crank has made a full turn. This piece is so placed as to abut on the piece T11 and throw the end T10 into mesh with the teeth of the wheel T4 and prevent displacement of the platen by momentum. A small spring T14 over the end of the bellcrank arm T11 tends to throw the point of said lever into mesh with the same. Now when the end of a line has been reached, and it is desired to return to the beginning again and commence a new line, the operator has merel)r to push against the lever TG and the carriage will not only be pushed back to the end of its travel,but the roller will be turned through a greater or less arc, according to whether the piece T12 is turned up or down, for on pressing the lever TG toward the platen the link T7 is drawn downward and the piece T5 revolved with the pawl upon it until the wheelis turned through the required distance. At this moment the piece T12 or the end of the bell-crank itself comes in contact with the end T11 and the point T10 is forced against the teeth of the wheel, thus stopping positively all further movement and preventing the possibility of any bad effects from the inertia of the parts in carrying the roller too far.
Two brackets U extend upward and Lhack- Ward from the carriage behind the platen, and into notches in the ends of said brackets are fitted the ends of the axle of a roller for holding the rubber bands that carry the paper, as shown at U in Figs. fl and A standard U2 in front of the roller has bearings carrying two more rollers Ui'1 and U1, and around all three of these rollers there are two or more rubber or other flexible bands U5,which press tightly against the platen and keep the paper securelyin place. Ly the use of the bands in this manner I am enabled to assemble and feed as many as twelve or lifteen sheets of paper at a time for multiple work without the least danger of any of them slipping.
A paper-scale is provided,which is pivoted at the ends of the carriage by means of the side arms V` and at one end of the carriage the pivot extends through theV bracket and has fastened to it atI the outer end a holdingpiece V3, provided with two notches, as shown in Fig. 4, while a spring V1, fastened to the outside of said bracket, is provided with a point which tits into said notches and holds the piece in either position desired. Now, by taking the handle V2 and thrusting the same backward, the paper-scale lnay be thrust away from the platen and the paper carried over the same and under the scale. lVhen thepaper is so adjusted, the scale is again IOO ITO
brought forward and the paper held secure by the action of the peint of the spring against the piece V3.
Underneath the platen and in. the path of the point of the bell-hammer is arow of holes XV, into which a peg W" is adapted to be fitted. Parallel with these holes l there is placed a graduated scale,wl1ich is preferably made to correspond with the graduations on the paper-scaleV. This scale has lines pointing to the various holes in the row YV, and by placing the peg XV into a hole opposite any one oi' these lines the point of the hainmer may at any point be brought into contact therewith and the bell be made to ring at any time during the travel ot the carriage. This is a convenient feature for those persons who may wish to employ paper of various widths.
Just back of and under the back rod of the carriage there a strip attachmentor ferrule adapted to be screwed or otherwise attached to the machine, and which is perforated, as shown, for the reception of a peg similar to that used under the roller. This strip X has numbers placed thereon opposite the various holes and which correspond with the numbers upon the scale above the platen. The peg is so proportioned as to project into the path of the boss Q and stop the movement of the carriage at any desired pointof the backward travel and thus secure any width of n'largin desired.
rlhe reason otl another detail of construction has a further advantage. N2 connects with the release-bail through a spring instead of by rigid mechanism, on account of the shock and strain that would otherwise result to the wire bail when the handle of the lever actuating it was pushed far enough to allow ofthe operators pushing the carriage as is desired when this bail is employed forreleasing the feed-pa'wl.
The broad features of the throwing device and detent for the in king-spools are claimed in my application, Serial No. 272,565, pending simultaneously with this application.
