THEODORE FREDERICK BOURNE, OF CLIFTON, NE\V YORK.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 446,850, dated February 24, 1891.
Application filed January 21, 1890. Serial No. 337,611. (No model.)
To all whom it may concern.-
Be it known that I, THEODORE FREDER- ICK BOURNE, residing in Clifton, Richmond county, New York, have invented certain new and useful Improvements in Type-biting Machines, of which the following is a specification.
My invention relates to that class of typewriters in which a series'of keys or levers are actuated by both hands of the operator, and
more particularly to the class wherein the types are carried on a segment or type wheel, and in which a hammer is used to cause an impression to be made on paper.
Theobject of the invention is to so simplify and improve the construction of a typewriting machine that comparatively few parts will be needed to produce a machine capable of being operated by both hands to effect fast writing, and in which the parts will not be likely to get out of order. I
The invention consists in novel means for turning a type segment or carrier to bring the types into position for printing, as more fully hereinafter set forth.
Also in novel means for actuating a hammer to cause the types to produce impressions on paper, &c.
The invention further consists in the novel details of improvement and the combinations clined face by means of which the type segment or carrier is turned. Fig. 5 is a face view, enlarged, of the type segment or carrier. Fig. 6 is a vertical sectional view of the type segment or carrier, showing how the types are supported. Fig. 7 is avertical 1011- gitudinal sectional view on the plane of the line 0 c, Fig. 1. Fig. 8 is a detail view of the escapement for the paper-carriage. Fig. 9 is Fig. 4 is a plan view,. enlarged, of the bar or lever having the ina detail sectional view on the plane of the line 0 c, Fig. 1, showing the parts in the position they assume when the type segment or carrier is turned and the hammer thrown by the depression of a key-lever. Fig. 9 is an edge view of the hammer and its actuating connections. Fig. 10 is a detail front View of the paper-carriage and the mechanism for driving it. Fig. 11 is an edge view of the bar for turning the type segment or carrier, showing also the means for holding said bar in its normal position; and Figs. 12, 13, 14, and 15 are detail views of modifications, hereinafter more fully described.
Referring now to the accompanying drawings, the letter A indicates the frame of the type-writer, which may be of any suitable shape and construction.
B is a shaft shown in a vertical position,
which shaft is journaled in suitable bearings in the frame A. The shaft B is adapted to support and actuate a type segment or carrier D, as hereinafter more fully stated. To the shaft 13, preferably near its lower end, is secured a bar or lever E, by means of which the shaft 13 is turned on its longitudinal axis or lever E. One face or side of the bar or I lei'er E is inclined, as shown, so that when a pin or rod is pressed upon said incline said bar or lever will be moved or turned on its pivot to turn the shaft B.
F are a series of key-levers that are suitably pivoted or hung on a rod-a, carried by the frame A, or they may be otherwise suitably pivoted in the frame. The key-levers F extend over the-bar or lever E and at about right angles thereto when the latter is in its normal position. (See Fig. 7.) The key-1evers F are supported so as to have free up and down movement at their outer or free ends by springs b, one for each lever F, said springs Z) being suitably secured to the frame A. (See Fig. 7.) The key-levers F, at their outer ends, pass between suitable guides at, which act to prevent lateral movement of said key-levers, and the latter are held up Each key-lever F carries a projection or pin f, that is situated above the inclined face of the bar or lever E. (See Figs. 3, 7, and 9.) \Vhen a key-lever F is depressed, its projectionfis forced or pressed against the inclined face of the bar or lever E, and as said bar or lever is pivotally carried by the shaft B it will move or swing under the advancing projection f, and thereby the shaft B will be turned. As some of the key-levers F are on one side of the shaft B and some are on the opposite side, the shaft will be turned either to the right or to the left, according to which side the key-lever that is moved to actuate the bar E is on. (See Figs. 3 and 9.)
In order to check the movement of the bar or lever E, and thereby the shaft B, and to hold said shaft or bar firmly while the type is being impressed on paper, as hereinafter shown, I provide a series of holes or apertures g in the bar or lever E, each of which holes is adapted to receive a corresponding projection f, as indicated in Figs. 3 and 9.
In Fig. 4 each series of holes 9 on opposite sides of the shaft 13 is shown arranged in the arc of a circle, the arrangement of the projections f and apertures or holes 9 being such that the nearer they are situated to the shaft B the more the bar or lever E, and thereby the shaft 15, will be turned, and the farther they are away from the shaft 13 the less it will be turned; or, in other words, when the bar or lever E is in its normal position or at about right angles to the key-levers F the type G at about the center of the type segment or carrier in Fig. 1 is in position to be impressed upon paper. \Vhen now the keylever at the extreme right or left is depressed, the bar E will be turned slightly to bring the type next to the center type into position to be struck, and the type-carrier will then be moved but slightly; but if the key-lever next to the shaft be depressed the bar E, and thereby the typecarrier, will be swung around to bring the type nearest the outer edge of the carrier into position to be struck, and so on for all the key-levers, the type-carrier D being turned more or less according to the distance the key-lever that is depressed is from the shaft 13. After the projectionfhas passed along the inclined face of the bar or lever E sufficiently far to turn the shaftB the distance desired to bring the desired type into position for printing, said projectionf will pass into or through its corresponding aperture or hole g, and thereby will automatically lock and hold the bar or lever E from further movement until the projection is withdrawn from said aperture.
In order to insure that the proj ection f will positively pass into its corresponding hole g in the bar E and not ride past it, I place an upturned ledge 7L in front of and about in line with the outer edge of the holes g. By this means, when the projection f has passed along the inclined face of the bar E sufficiently far, and thus turned the bar, the proor lever E.
jection will be arrested by the ledge 71. and will then pass through the hole 1 to lock the bar E. By arranging theholcsg in the proper places on the bar E the movement of said bar for each projection f of the key-levers F can be regulated, whereby each key-lever regulates the distance the type-carrier shall be turned in either direction. After the bar or lever E and shaft 13, and thereby the typecarrier, have been turned to bring the desired type into the printing position, and after the impression has been made, (as hereinafter shown,) the bar E and type-carrier D should be returned to their normal position ready to be moved again. This can be accomplished by means of a spring or springs suitably arranged for the purpose. In the drawings I have shown two spring-arms i i, one on each side of the shaft 1 and suitably secured to the frame A. (See Fig. 3.) Each springt' is adapted to press against a corresponding pin or the like, one on each side of the shaft B,
the tendency of said springs being to return the bar E (and thereby the shaft B) to its normal position, or at about right angles to the key-levers F. The bar or lever E should be held in its normal position until a key-lever is struck, and should be instantly stopped on its return movement when it reaches its normal position. I prefer to effect the above as follows: If II are two levers, shown extending about parallel with the key-levers F, and preferably rigidly secured to a rock-shaft Z, suitably hung in the frame A, so that both levers II will move in unison. The levers II carry projections or stop-pieces on, each of which is adapted to be engaged by a pivoted dog or the like a on opposite ends of the bar (See Figs. 3, 7, 9, and 11.) The levers II should be held up in position for the dogs a to engage the projections m, Fig. 7, by a suitable spring. Aspring-rod 0, passing through the shaftland resting against the frame A, as in Fig. 7, will answer. Each time a key-lever F is depressed the levers II, and thereby the projections m, should be lowered to free the dogs a from the projections in, and to thereby permit the bar or lever E to freely turn under the advancing projection f. This is or may be effected by means of a cross-bar 1), secured to the levers II and extending across the machine beneath the series of key-levers F. (See Figs. and 7.) When new a key-lever F is depressed, it engages the cross-bar p and depresses the levers II, thereby moving the projections m below the dogs a on the bar or lever E, whereby said bar is now free to be moved by the advancing projection f, as before shown. \Vhen the key-lever F is released, it rises under the influence of its spring I), the levers II If also then rising, thereby returning the pro jections m to their upper or normal position, so that as the bar or lever E is returned by its spring '5 the dogs 01 will encounter the projections m, and thus the bar or lever E will be brought to rest in its normal position.
depressed the desired distance.
The projections f, toward the outer sides of the series, will reach their corresponding holes 9 sooner than the projection nearer the shaft B; but this will not afiect the bar 19, as the levers F must all be depressed the same. or a certain distance to cause the bar 19 to be If the projection f passes into the hole 9 before the bar 19 is depressed the desired distance, it can simply pass freely through until the lever F or bar 19 is depressed the desired amount.
The t e se ment or carrier D is shown in' the form of a three-cornered open frame, having at one corner a tubeq, into which the shaft B projects, whereby the type-carriers D can be moved up and down on said shaft. A pin and slot 1" s between the tube (1 and shaft B causes the type-carrier to be turned with and by the shaft B, while permitting up-anddown or longitudinal movement of the typecarrier on said shaft. The outer side of the type segment or carrier D, or the side opposite the tube q, is shown curved or in the arc of a circle described from the shaft B. On this curved edge of the type-carrier D are a series of outwardly-projecting pins if, there being one series of such pins t on the upper part u and a corresponding series of pins on the lower part a of the type-carrier, as in Figs. 3, 5, 6, 7, and 9. The types G are carried on bars I, that are provided with apertures v to receive the pins t, whereby said bars are hung on the type-carrier D and are permitted movement on the pins 15. (See Fig. 6.) The bars I are shown extending parallel on the outer side of the curved part of the type segment or carrier D, and the types G on the several bars are arranged in rows and in alignment, so that all the types of each row will be in perfect line. Three rows of types are shown, (see Fig. 5,) the small letters being in the lower row, the capitals in the middle row, and the figures and punctuation-marks,
, &c., being in the upper row; but the above arrangementof types can be varied as desired.
The-types G on the type-carrier D are arranged in proximity to a roller or platen J on a paper-carriage L, that is suitably guided on the frame A. The bars I, and thereby the types G, are adapted to be pressed forward, so that the types can make an impression on paper M, that passes over the roller J. (See Fig. 9.) The bars I may be moved back on the pins t by a suitable spring or spring-band to, which also acts to hold the barsI against the type segment or carrier. (See Figs. 5 and 6.) Said spring-band to may be made of rubber an elastic band, for instances-and extend around the type-carrier and press against the bars I to hold them in position.
The type segrn cut or carrier D is preferably normally held elevated, so that the lower row of type G will be in line with the paper-roller J. (See Fig. 7.) This is or may be accomplished by means of a spring so, coiled around the shaft B and resting at one end against the stop-bar e and at the opposite end against row of types in line with the roller J. By:
means of a connection .2', extending from one side of the swiveled platey to a lever F, the
type-segment will be drawn down to bring the row of capitals in line with the roller J by depressing the said lever. So, also, by a connection .2, extending to the lever F, the type segment or carrier D will be drawn down to bring the upper row of types in line with the roller J. The spring .1; acts to return the type-carrier D to its normal position when the lever F or F is released.
To cause an impression of the types to be made on paper, I provide a hammer that is adapted to strike the inner side or shank of the type to drive it forward. I have devised a very simple arrangement for causing the hammer to strike a type and then to be reset to strike the next type, and so on. N is a hammer adapted to strike a type or the bar that carries it. (See Fig. 9.) The hammer N is pivoted, as at a to a suitable standard b carried by the frame A, (see Figs. 7 and 9,) and it is adapted to have pressure exerted upon it on opposite sides of its fulcrum for moving it in opposite directions. purpose said hammer is shown having a slot or groove d extending both above and below the pivot a, as shown. 0 is an arm or. bail that has a side projection or bar e (shown passing into or through the slot d said pro-- For this IOO jection or bar being adapted to slide along the slot or groove (Z from the position shown in Fig. 7 to that'shown in Fig. 9, and thereby to exert pressure on the hammer. The arm or bail O is pivotally carried so as to have an up-and-down motion, and is preferably The arm or bail O has an of said spring to press against the arm or bail O and its other end against the arm f (see dotted lines, Fig. 9;) but of course the spring for moving the arm or bail O in the direction of the arrow 2 could be otherwise arranged, if desired.
The above parts operate as follows: Vhen the parts are in their normal position, the bar e of the arm or bail 0 will be near the upper part of the slot or groove d and as that point is above the pivot a the action of the spring will throw the upper part of the hammer N outward, as in Fig. 7, or away from the'types G. lVhen now a key-lever is depressed, the cross-bar 1) will be lowered,
action of the spring will throw the lower end of the hammer N in the direction of the arrow 2, thereby throwing the upper end of said hammer forward, causing it to strike a type and drive it forward to print. hen the key-lever F is released, the cross-bar]; will rise, thereby carrying up the bar or bail O, causing the projection or bar 6 to pass up in the slot or groove (1 and when it passes above the pivot (17 it will throw the upper end of the hammer backward or in the direction of the arrow 2. From the above it will be seen that the single spring g tends to move the hammer in two directions-that is to say, forward to strike the type and backward into the normal position, ready to be driven forward again.
The hammer coacts with the type segment or carrier D as follows: \Vhen the key-levcr F is depressed, its projectionf rides on the inclined face of the bar or lever E, and thus turns the type-segment to bring the desired type in frontof the paper-roller J, while at the same time the arm or bail O is lowered to draw the part 6 along the slot or groove (1 After the projection 7" reaches and passes into its corresponding aperture or hole gin the bar E, to hold the type carrier in the proper position the part c of the arm or bail is sufiiciently far below the pivot a to cause the upper part of the hammer N to be moved forward to strike the type held in line with it; but the hammer N should not be thrown until after the projectionf has entered its correspondingapertureg in the bar E. \Vhen the key-lever F is released, the parts all return to their normal positions, as before shown.
In order to insure that the hammer N will not be thrown untilafter the type to be struck is brought tothe proper position,[ may pivot to said lever a dog '11 above the pivot (t the outer end of which dog comes against a projectionj on the cross-harp, as in Fig. 7, or it could rest directly against the cross-bar p. The projection j is adjustable up and down, so as to regulate the time at which the dog '6 shallslip over said projection when the cross-bar 1) is lowered. ly means of a slot Z in the projection f and a screw Z" passing through said slot and into the cross-harp the projection can be adjusted vertically on the bar 1). The above parts are to be so adjusted that the projection f will remain in front of the dog i until after. the projectionfof the key-lever F has passed into its respective ap' erture g in the baror leverE and the proper type Ghas thus been brought into position to be struck by the hammer. Then when the projection f passes farther into the aperture 9 the projection j' will pass below the dog 6, thus permitting the hammer N to be thrown by the bail and spring 9 all as before clearly stated and as shown in Fig. 9. The upper end of the hammer N is preferably guided in a slotted projection or arm m carried by the frame A, as shown in Figs. 1, 7,
and 9. By this means the hammer is guided to insure its striking at the proper point.
The paper-carriage L is adapted to move step by step as the several types are struck, as well known in type-writing machines.
The paper-carriage may be of any suitable construction and actuated in any desired manner. I have shown one means for this purpose, as follows: The paper-carriage L (shown in the drawings) consists of a suitable frame, which is provided at one corner with suitable eyes or sockets a 11%, that slide freely on a guide rod 0 suitably supported on the frame A. The opposite side or corner of the papercarriage is shown provided with a roller-p that travels on the part (1 of the frame A.
lly the above means the carriage L is supported and guided. To drive the paper-carriage to the left, I have shown a roller 0' secured to a shaft suitably hung in bearings in the frame A. A cord or other suitable connection f is connected at one end to the carriage L andat its otherend to the roller 7' so that as the roller 0' turns it will wind up the cord 1?, and thus propel the carriage. To turn the roller 2' to drive the carriage, I have shown a cord or the like r that at one end is secured to the shaft s and adapted to be wound on the same and at its other end it is connected to a spring 20, secured to the frame A. \Vhen the carriage is moved to the right by the operator, it turns the rollerr and shaft s thereby winding the cord 1 on the shaft .9 and distending the spring'w but when the carriage is released the spring retracts, and thus turns the shaft s and roller Win the opposite direction, thus winding the cord t on the roller 4' and moving the carriage to the left. 13y securing the spring 10 to an adjustable hook or the like 10 the tension of said spring may be regulated.
The paper-carriage is adapted to move step by step, and for this purpose I have provided the following arrangement: P is a rack carried by the paper-carriage L and adapted to be engaged by a stationary dog a and a movable dog I). (See Fig. 8.) Said dogs are carried by a rocking bar d, that is hung in suitable hearings in brackets 6 suitably supported by the frame A. (See Figs. 2, 7, and 8.) The rocking bar (Z carries a crank-arm f that is connected by suitable links g h" f is drawn down by the depression of the bar 1) the dog o will pass between two teeth m on the rack P, thereby moving the dog I) from between two teeth in" and to one side of the rack P and permitting the spring Z" to draw the dog I) back the distance of one tooth, as in dotted lines in Fig. 8. \Vhen now the cross-harp rises, the bar (1* will rock back, causing the dog a to pass out of its tooth-space m and also carrying the dog 1') between two teeth, (see Fig. 2,) the spring "to now acting or being permitted to draw the carriage L, which moves the dog b from the dotted position to the full-line position in Fig. 8, said dog abu ting against the stop i Each time the crankf is moved down and up the carriage will be fed forward one step or the distance between two teeth on, the dog a always acting to hold the carriage, while the dog b 'is moving back to engage the next tooth to feed the carriage. It will be seen that the two feed-dogs a 12" do not pass be tween the same teeth m at the same time, but each passes between a different set of teeth, and that said dogs are situated at a distance from each other along the rack P. A suitable spring n may be used to turn the bar d back after ithas been moved by the downward motion of the bar 19, or the link q can move the bar d in both directions.
When the carriage Lis to be moved to the right in Fig. 1 to commence a new line of writing, the rack P should be. disengaged from the dogs a 11 I pivot said rack P to the carriage L, as .at 0 so that it can swing outwardly free of said dogs, as in dotted lines in Fig. 2. One pivot 0 of said rack P is shown connected by a crank 13 and link 1 with a lever R, that is hung on the shaft 8 of the roller J. 'W'hen the lever B is turned on its pivot, it draws on the link g and crank 19, thereby rocking the rack P on its pivot free from the dogs a b, all as in dotted lines, Fig. 2. A spring t, connected at one end to the lever B and at its other end to the carriage L, draws the lever B against a stop-pin 1%, thereby holding the parts in their normal position. The lever R also carries a dog o that engages a ratchet-wheel 10, connected with the paper-roller J, so that when the lever B is turned it will turn the paper-roller. The parts are so arranged that the moving of the lever B to roll thepaper M for another linespace will also and simultaneously move the rack P out of engagement with the dogs a b to permit the carriage to be moved to the right ready for another line to be written. In order to regulate the distance between lines, I have provided a rod so, that is adapted to turn in bearings on the carriage L, said rod carrying a pin 3 that is adapted to come in line with the lever R to limit its movement.
S is a roller parallel with the roller J, hung in suitable bearings in the carriage L. Suitable springs a at the ends of the roller S tend to press it against the roller J. The paper F1 is passed between the rollers J and S and is carried around the roller J by fricor both, as shown,) as at 6 per M from between the rollers J S to be properly guided. (See Fig. 9.)
T is a space-key lever for making the spaces between words, and it is shown as extending parallel with the key-levers F and situated at about the center of the series of key-levers. In order that the space-key T will not actuate the cross-bar p to operate the hammer N, I cut away part of said space-key over the crossbar p, (or cut away the cross-bar 19, one The space-key T is connected by a link f with the crank f so that when the space-key is depressed the carriage will move along a step to make a space without a type being struck.
The inking-ribbon U is to pass between the type G on the type-carrier D and the roller J, so as to be pressed by the type on the paper M. Said ribbon may be carried and actuated in any suitable manner. The means I have shown for this purpose is as follows: V is a bar pivoted to the support m said bar V at its ends carrying rotary uprights 9 h are ribbon-spools that are removably carried on the uprights 9 the inking-ribbon U bein wound around said spools, as in Fig. 1. Said ribbon is passed over guide-posts i carried by the frame A, saidposts being arranged to guide the ribbon between the type and roller J. As shown in Fig. 1, the ribbon U passes over the side of one spool 71 next the roller J, while said ribbon passes over the outeror opposite side of the other spool. Said spools are turned to actuate the ribbon as follows: Each upright g carries loosely a gear-wheel 7 that is adapted to mesh with a rack Z",car ried on the carriage L. The gear-wheel j carries a pawl m that engages a ratchetwheel at, fast on the upright 9 (See Fig. 2.) W'hen the gear-wheelj on the left is in gear with the rack Z and the carriage moves to the left, the upright g and spool 72. will, by the pawl m and ratchet 12 be turned, and thus wind up the ribbon U and unwind it from the opposite spool. hen the carriage is moved to the right, the pawl m slips on its ratchet, thus permitting the spool to stand still. \Vhen it is desired to have the spool on the rightin Fig. 1 turn to wind the ribbon, the bar V is turned on its pivot, which moves the gear-wheel f on the right into mesh with the rack Z and draws the gear on the left out of mesh with said rack. The winding of the ribbon is effected, as shown above, on the other spool.
Of course I do not wish to confine myself to the precise means shown for carrying out my invent-ion, as said means can be modified or changed without departing from the spirit of my invention. Instead of the type segment or carrier D and the inclined bar E being on the same shaft, they may be on separate shafts and connected together, so that one will actuate the other by means of suitable gearing. Such an arrangement is illustrated in Figs. 12 and 13, wherein the shaft l; carries a toothed wheel that gears with a toothed segment or the like 3, carried by a shaft or arbor 4-, that supports the inclined bar E. The arbor t is suitably guided in the frame A, and as the pinsf descend to turn the inclined bar E the segment .3 will be turned, and thereby the shaft B and type-carrier 1).
In Fig. ll I have shown a modification of the means for locking and hold ingthe inclined bar or lever E when it is turned. This consists of a pin f carried by the key-lever F and at a suitable distance from the pin f, so that when the bar or lever E has been turned a suitable distance to bring a certain type into printing position said bar will encounter the pin f and stop further movement of said bar, whereby the latter will be held in the desired position.
In Fig. 15 the pin f for actuating the inclined bar E is separated from the key-lever F and is guided in bearings 5, suitably carried in the frame A. A spring 6 tends to keep the pin 1 elevated and to return it to its upper normal position after ithas been depressed to turn the inclined bar E.
Of course it will be understood that suitable finger-keys 7 are to be placed on the levers F, (or on the pins f, Fig. 15,) as usual, which keys may be provided with suitable letters or symbols, as in Fig. 1.
It will be seen from the preceding description that the bar or levcrE is turned in a plane at about right angles to the plane of movement of the pins f, whereby the described effects are produced. It will be found that when the pins f turn the inclined bar or lever Iii they pass over its surface in the arc of a circle, because the pivot of said bar or lever is at one side of the pin f.
Other means than that described for arrestng the bar or lever E and for holding it in its normal position-may be used, if preferred.
The type-bars I could be supported and carried on the type segment or carrier D otherwise than by the pins 25, if desired, so that they can have lateral movement, as before shown.
By placing the spring as shown its tension remains even on the bail or arm 0, so that whether the arm 0 is raised or lowered the tension hardly varies; but said spring can be otherwise suitably arranged. The support f for the bail or arm 0 may be made adjustable on the cross-bar p by means of slot f and screw 51 (see Fig. 9) to regulate the passage of said bail in the slot (1 of the hammer N, or with reference to the pivot of said hammer.
Having now described my invention, what I claim is- 1.
