Application filed May 20, 1897. Serial No. 637,470. (No incdeLl T0 (0 107L071). it may coiwern:
Beitknown that LJosn DELGADO AGUILAR, a citizen of the United States, and a resident of the city of NewYork, in the county of New York and State of New York, have invented a new and useful Automatic Type-Writing Machine, of which the following is a specification.
My invention relates to that class of typewriting machines in which a number of typebearing arms are thrown successively against the paper or other substance to be written on by the depression and release of a series of keys, and while the type and key are going back to place the paper or substance is moved a type-space distance.
The main object of myinvention is to provide a simple and fast writing-machine. lVith this object in view I have provided means by which those features of the type-writing machines in use that annoy and waste the time of the operator-are corrected. These are, first, pulling the carriage back; second, turning the platen for the required space between lines; third, the blind writing and top or front visible writing, and, fourth, the margins.
I correct the first feature by providing the machine with an automatic carriage, which when writing from margin to margin it moves leftward a type space distance at the time, but at the end of the line of writing it suddenly returns to the right and stops at the proper place for the beginning of the next. The second is corrected by an automatic platen-turning device, the third by arranging the type-bars in such way as to write at an angle of forty-live degrees, from the top of the platen, and on the side fronting the operator, and the fourth by placing the marginal stops on the front bar of the paper-carriage, on which they slide, and can be secured at any desired place. The machine is also provided with a paragraph device to avoid the adjustment at the beginning of a paragraph and with an inking-roller to improve the inking of the types. The features of construction and combinations by which these improvements are effected are hereinafter more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a top view of a type-writing machine embodying my improvements. Fig. 2 is a central vertical section of same; and Fig. 3, a rear elevation of same, showing the impelling mechanism. Fig. i is a vertical section on the line w or of Fig. 1, showing only enough of the machine to illustrate the capitalsshifting device. Fig. 5 represents the spacer or universal bar and the'position of the inking-roller and pawl. Fig. 6 illustrates the platen-turn ing device. Fig. 7 shows the tension-release blade in its two positions. Fig. Sis a top view of the releaseshaft. Fig. 9 shows the action of the platen-turning pawl, and Fig. 10 the action of the paragraplrstop; Fig. 11, the automatic platen-turning device; Figs. 12 and 13, the paragraplrstop; Figs. 14, 15, 16, 17, and 18 the type guides, moving arms, and keylevers, respectively, and Fig. 19 shows the adjusting-key and release-shaft in position? In the several views the same part will be found designated by the same numeral or let= ter of reference.
1 represents the bed-frame, and 2 the carriage orplaten support, the rear bar 5 of which is grooved in its lower side, so as to telescope a channel (5, firmly secured across the rear of the elevation of the bed-frame 1 and on which slide over two balls inclosed in said channel This arrangement affords an easy sliding place to the carriage and prevents it from being pushed upward by the tehsion-gear. The front bar of the carriage 8 rests by gravity and slides on two balls inclosed in another channel 7, fastened across the front of the elevation of the bed-frame 1.
3 is the paper-frame, which is held in posi tion by means of bars 9, projecting outwardly from the center of its two lateral sides and fitting in openings made for the purpose in the corresponding sides of the carriage 2. These projecting bars 9 are bored lengthwise in the center for the passage of the platenshaft 10, to which they serve as bearings.
On the front bar of the paper-carriage slide two marginal stops 11, consisting of small blocks bored for the passage of the bar and provided with thnmbscrews to secure them firmly at any desired place. In the inner side of these blocks are secured the paper fingers or guides 12, which encircle about half of the periphery of the platen and are brought as near to it as possible. In the lower ends of these marginal stops are attached arms 13, projecting downward and of sufficient length to knock against the bend 14 of the releaseblade 15.
On the rear bar of the paper-carriage are secured, by means of blocks 16, rigidly secured to it, and springs 17, the pressure or feeding roller 18 and, by blocks 19, the papertable 20.
to On the front side 8 of the carriage 2 is a sliding blade 22, checked by pins 23 and having its two ends bent upward, as seen in Figs. 6, 10, and 11. One of the ends is again bent in the former direction and prolonged for a short distance, being provided with a bore or hole 24, through which passes the projecting arm of the platen-turning device 26. The sliding blade 22 is also provided with a number of teeth on its inner side or that toward the platen to be engaged by the automatic platen-rotating device hereinafter referred to.
26 is a vertical lever pivoted at A to a support 27, firmly fastened to the inner side of the front bar 8 of the carriage 2 and having its upper end so shaped as to fit the fingers of the operator. On one side of its lower end is pivoted a pawl or dog 29, Fig. 9, which when raised engages the ratchet-wheel of the platen, causing its rotation. Opposite to the pawl,
30 in the same end of lever 26, is a downward projection or arm 25, that goes through the bore 24 of sliding blade 22.
31 is the line-space regulator, consisting of athumb-screwsliding in an inverted-T groove 3 5 g on the upper left-hand side of the front bar 8 of the carriage 2 and provided with a nut n, placed in the inner and wider side of the groove, which it loosely fits to allow it a sliding motion in the direction of the groove and by means of which the thumb-screw can be secu red at any desired place within the length of the groove.
32 is a ratch or toothed plank firmly secured to the back of carriage 2, rear bar 5, and be- 5 ing engaged by the tension-gear 33. This tension-gear is rigidly attached to the lower side of channeled support 6 (in the rear of the elevation of the bed-frame 1) by plates 37, forming the cam or inclosure of the watchspring 38, attached to the shaft 39 of the tension-gear 33. The gear is provided with a check 40 to fix it on the shaft 39, to which is attached a small ratchet-wheel.
34 is a catch fulcrumed at its lower end to impelling-lever 35 and serves to impel the carriage by successively engaging the teeth of gear 33.
35 is a lever of the third class f ulcru med at B to plates E (one of them being removed for clearness) and serving to raise and lower the impelling-catch 34.
41 is a retaining-catch fulcru med on plates E and serving to retain the tension-gear 33 as the catch 34 ascends to engage the tooth of the gear next above it.
42 is a spring which, acting on lever 35,
when raised, rotates by means of catch 34 the tension-gear 33.
43 and 44 are two weak springs serving to keep catches 34 and 41 in constant engagement with the tension-gear.
15 is a release-blade fulcrumed at its lower end 46 to end 45 of releaseshaft 51, on which it rotates freely. It bears near that end an inward-projecting pin 47 to engage another pin 49, attached to that end of shaft 51. In its upper end it has a projection in which fits the hollow end of bend 14 and an enlargement at H,by which the bent catch C holds it in the position shown in Fig. 7. The bent catch 0 is also provided with a bend a, fitting on its projection 0'. These bends when in the machine almost rest on the sliding blade 22 and serve to release and lock the tension-gear 33 and to prevent the carriage from sliding out of the machine.
51 is a release-shaft journaled at the end 6 to plate E and at the other, 53, to support 55, held fast on both sides of the bed-frame 1. It has firmly secured near end e two bent wires 50 and 52 to act when the shaft is retated on catches 34 and 41, causing the release of gear 33. x
F is a projecting wire firmly secured to the left side of release-shaft 51 and on which rests a bent wire G, pivoted on the cross-lever Z of adjusting-key L. This combination causes the rotation of shaft 51 when the key L is depressed.
M is a downward-projecting wire rigidly secured to shaft 51 and bent in its lower end m. This bend when the shaft rotates passes over the rear end of spacer-bar 36 and locks the keyboard.
58 is a small bent lever, as seen in Figs. 10 and 13, having near its lower bend an enlargement where it is fulcrumed on a horizontal bar 56, which extends from the left side of the bed-frame to about the center of channeled support 7. On this horizontal bar the bent lever 58 easily slides between two guides 57, in the back of which is fulcrumed the paragraph-adj ustin g lever 61. Paragraph-adj usting lever 61 projects out of the bed-frame 1 on the left side andis toothed on the under side to fix it after adjustment on catch 63, secured to the bed-frame. It is provided with a knob in its outer end and with a graduated scale on its front side. A spring 62, pressing on its upper side, prevents it from slipping out of catch 63.
The upper bend of lever 58 or paragraphstop is so placed that when slightly turned,
IIO
as seen by dotted lines in Fig. 10, it gets in the way of the bent end of sliding blade 22 of the platen-rotating device.
60 is a cross-bar pivoted on the upper side of the bed-frame and connected by rod 64 to the rear end of paragraph-key lever P. It passes over the lower bend of paragraph-stop 58 and serves to turn the stop when the paragraph-key is depressed. 1
emcee 'P is a lever of the third class, pivoted at (Z and having an upward-projecting arm, on which fits the key 0. Its rear end almost rests on cross-lever Z, which it carries down when depressed.
K represents the keys, K the key-levers, and R the cross-bar, on which the key-levers are fulcrumed. These levers belong to the first class, having a straight upward bend on the front arm to receive the keys and a semicircular one on the rear arm to engage the lower arm of type-moving lever T, for which purpose they are provided with a pin, as seen in Fig. 17, to engage the fork of lever T.
T is a gun-shaped lever of the first class, pivoted on the front of guide \V. Its lower or smaller arm is bifurcated, as seen at T, Fig. 16, to receive the pin of the key-lever. T, Figs. 16 and 18, show another construction, based on the same principle of lever T and key-lever K. The upper or longer arm is pivoted to the type-bars V.
V are the type-bars. They are pivoted by one end to guiding-arms T and on the other are secured the types. Guiding-arms T are pivoted at their other end to their respective guides IV. Guides .V are formed by two sheets of metal (steel, preferably) of sufficient thickness to rigidly guide the type bars from rest to the platen. Every typebar is provided with an independent guide. They may be stamped out with a die, as shown in Fig. 14, and bent, as indicated by dotted lines, to their proper shape, as in Fig. 15, the projections to and '20 serving to secure them to supports S and S. Each type-bar V has in the end V three types 2/, n, and o. Types n are the capitals, 1* the small letters, and o the numerals and other characters. \Vhen the type-frame 69, on which are fulcrumed or fastened the types, key-levers, spacer or universal bar, and the inking device, rests in its natural position, the small letters 2; are printed on the paper. lVhen depressed by means of the capitals-shifting key, the capitals u are printed, and when raised by the ligtires-shifting key the figures and other characters o are printed.
Q is the capital-shifting key, attached to an upward projection of the third-class lever q, fulcrumed at (Z and pivoted at g to a shoulder Z. This shoulder is fulcrumed at z to the bed-frame and, rotated by lever q, slips away from under the type-frame. As the typeframe is fulerumed at on cross-bolt 71 of the bed-frame l and has no support on its front side, it falls by gravity to the position shown by dotted lines in Fig. i.
Y is the figures-shifting key, attached to a lever of the second class Y, fulerumed at (Z and resting on the short arm of the first-class lever 3 This lever is fulcrumed at y to the bed-frame, itslongerarm reaching under the type-frame 6!), which it raises when the key Y is depressed.
l) is a small blade or lever fulcru med at Z) 'on the inner side of cross-channeled support 7 of the bed-frame. Its lower end is bifurcated and bent inwardly, so as to receive the release-blade 15 between the two sides 2' and t", as seen at Figs. 7 and 11. In its upper end is fulcrumed a catch-wheel a, having a horn or projecting tooth 7L and two notches, in which catches the bent end of spring a, serving to arrest the rotation of the wheel. When in the machine, this device is moved by blade 15, and when the horn is in an upward position it arrests the motion of sliding blade 22, causing the platen to turn.
73 is the inking-roller, consisting of an iron core or shaft covered in all its length, except the ends, by an inking coating of some suitable material. Both ends of the roller fit on bearings attached to two connecting-bars 74, which are fulerumed on cross-bar 75 of the in king-frame 76. The two connecting-bars 7st may be joined together by one or two crossbars in order to give more rigidity to the structure. The rear cross-bar 77 of the inking-frame is prolonged beyond the twolateral bars 76 to meet both sides of the type-frame, on which they are fulcrumed at 78. On these prolongations are placed two spiral springs 79, so attached to both frames as to cause the downward push of side 75 of the inking-frame. The lateral sides have also a short prolongation beyond the cross-bar 75 to attach the ends of two springs 80, secured to bars 74. and serving to bring these bars in the direction of the sides 76. At the center of bar 77 is a small projection 81, to be acted on by pawl 82.
The inking-pad consists of a metal casing 83, supported by the type-bars resting-bar 8i and the type-bars guide-support S. The inner side of this casing is lined with some suitable material for holding the ink that the inking-roller will impart to the types and so shaped in its lower part as to surround and embed half the periphery of the roller. On both sides of this pad and aiding to its support are two roller-guides 85, Fig. 1, to prevent it from going in an upward direction and guiding it to follow the surface of the types.
The inking-roller acting pawl 82 is placed so that its rear end rests on the spacer-bar and its front one on the projection 81 of the inking-frame. It is fulcrum ed at 88 on cross support 89, fastened on hot 11 sides of the bedframe 1.
The spacer or universal bar 36, as seen more clearly in Fig. 5, is a rectangular frame ending at the rear in a single bar. It is fulcrumed,by means of cross-bar 86, to both sides of the type-frame 69 at 87. On its front side is placed the spacing-key and farther back a cross-bar 68, on which rest all the type-levers.
91 are two general guides rigidly secured to the type-frame 69, one on each side, and to the ends of the roller-guides 85, being bent toward a common pointin the platen. They serve to guide all the types to that common point,securing,in conjunction with the guides W of each type, a perfectalinement. Two knobs 92 are also providedfor rotating the platen by hand.
The operation of the devices mentioned is as follows: To place the paper in the machine, it is pushed downward between the platen 4 and the paper-table until it reaches the pressure or feeding roller 18, when by turning the platen in the direction of the arrow the paper, slipping between the platen and paper-fingers 12, will appear on the front side of the platen. When it reaches over the general guides 91 the'desired distance, the marginal stops 11 are to be adjusted to any required distance from the edge of the paper. This is done by loosening their thumb-screw and sliding them in either direction required and when at the desired place securing them again. Then the distance for the beginning of paragraphs is adjusted. This is accomplished by slightly lifting the paragraph-lever 61 and sliding it in either direction until the scale has the number desired over catch 63, when the lever is released. The scale of the lever starts at the knob, and whatever distance there be between the knob and catch 63 that same distance will be left between the margin and the beginning of the paragraph. To bring the spot on the paper where the writing is to be started between the two points of the general guides 91, thecarriage is pushed to the left, if it is to the right; but if it is to the left it must be released. To release the carriage, theadju'sting-keyisdepressed. This causes its lever L, which is fulcrumed at d, to be depressed in its rear end, carrying with it the left end of cross-lever Z, to which it is pivoted. As this lever is connected by bent wire-G to projecting wire F of release-shaft 51, it Will cause the rotation of this shaft and the release of the tension-gear 33 through the action of release- wires 50 and 52 on catches 34 and 41. Gear 33 being released, the carriage is free to move in either direction and can be left at any desired place. If the carriage is left alone when the adjusting-key is depressed, it will go to the right until the lefthand marginal stop 11 knocks against the bend 14 of release-blade 15, when it will stop. If the writing is then started, it will begin just at the margin; but if space is desired the carriage is pushed to the left the required distance. When a key is depressed, it pushes the front end. of the spacer down, as it rests on cross-bar 68 of the same; but being fulcrumed on cross-bar 86 its rear end will be raised, carrying with it lever 35. This will push upward catch 34, which will engage the tooth of gear 33 next above it, as seen in dotted lines of Fig. 3. The tension-gear 33 is held meanwhile by the retaining-catch 41. As soon as the key is released spring 42, acting on lever 35, will cause its downward movement,pullingby catch 34,which,being engaged to the tension-gear 33, will cause its rotation, and-as this gear engages the catch 32, attached to the carriage, it will be moved a type-space distance to the left. As the key-lever is de-' pressed, it being fulcrumed at R, its rear end will ascend, but as it is bent in a semicircle the extreme end will be directed toward the operator, pulling by the lower arm of the typebar-moving lever T, which it engages. The upper arm of T will go in the opposite direc tion of that toward the platen, taking along the type-barV,to which it ispivoted, and causing the impression of a type in the paper; When the rear end of spacer-bar 36 is raised, it pushes up the end of the pawl 82, resting over it, and depresses thereby the opposite one. This will push down the projection 81 of the inking-frame 76, causing the upward motion of the opposite side of the frame and of the inking-roller to the position shown in Fig. 2. While reaching this position the roller rolls under the' guides 85 and surface of the types, to which it imparts sufficient ink for the impression. The roller is returned to its position when the spacer is released by the springs 79 acting on the frame. When another key is depressed, the action of the parts referred to above will be repeated, so that each time a key is depressed a type will be .printed on the paper and the carriage will move a type-space distance to the left. When the end of the line of Writing is reached, the right-hand marginal stop 11 will knock and push to the left the bend c" of catch 0, that holds the release-blade 15 in the position shown in Fig. 7. This will cause the catch to release the blade, which is then forced to the position shown by dotted lines by spring 48. During the change of position of blade 15 pin 47, attached to its lower end, pushes pin 49 of the release-shaft 51, causing the rotation of this shaft, which by means of release- wires 50 and 52, acting on catches 34 and 41, releases the tension-gear 33. The rotation of the shaft locks the keyboard by passing the bent end m of its downward-projecting wire M over the rear end of the spacer-bar 36. The tensionspring 38, acting on gear 33, gradually increases in tension as the carriage is moved to the left. This increase of tension when the gear is released causes the carriage to return to the right. The carriage will travel to the right until the left-hand marginal stop 11 knocks against bend 14 of release-blade 15, which is brought to its first position before the carriage is stopped. In the change of position of blade 15 when released by catch 0 it pushes side 'i of the bifurcated end of the automatic platen-rotating device I), Fig. 11, leaving it in the position shown by the dotted lines; but the horn will then be at h, inwhich position it will engage one of the teeth of sliding blade 22 as the carriage brings it to the right, and as the resistance occasioned by spring a", to the rotation of catch-Wheel a, is greater than that for turning the platen, blade 22 is forced to slide to the left until it reaches the line-space regulator 31, when, being of greater resistance than that of spring a, the catch-wheel is turned, leaving the horn in the position shown at 7t, in which it will not interfere with sliding blade 22. As the release-blade 15 is returned to its first position by the left-hand marginal stop 11 it pushes side 'i of the same device, causing it to take the position shown by full lines, in which, by a similar action to the one already explained, blade is returned to its former position, leaving the horn as shown at 71 in full lines. hen the blade 22 is slid to the left, it pulls by arm 25 of the platen-rotating lever 26 and raises the side of the lever where the pawl is fulcrumed. This causes the pawl to engage the ratchet-wheel of the platen and its rotation. When a paragraph is finished, to begin the next the paragraph-key is depressed. The depression of this key causes the paragraphlever P to descend in its rear end, pulling by the right-hand end of cross-lever 60 by means of connecting-rod 6% and turning the paragraph-stop 58 as cross-lever 6O rests on its lower bend 59. This causes its upper bend to get in the way of the left-hand bend of sliding blade 22. In the depression of lever I, as its rear end almost rests on cross-bar Z of adjusting-key Ii, this cross-lever is pushed down, causing, as already stated, the release of the tension-gear and the return of the carriage to the right. In this return the bent end of sliding blade 22 knocks against the paragraph-stop 58, which after turning the platen stops the carriage. Now by releasing the key the new paragraph can be started.
By this mechanism, as maybe clearly seen, after the machine is properly adjusted and the writing started it may be continued without interruption until the page is finished. In cases wh ere errors or insertions are to be made by depressing the adjusting-key the carriage is free to move in either direction required, and as the type is printed between the two ends of the general guides 91 by placing the spot where the correction or insertion is to be made between these two ends it can be readily done.
