TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 447,773, dated March 10, 1891.

Application filed October 23, 1889. Serial No. 327,954. (No model.)

To aZZ whom it may concern:

Be it known that I, AUDLEY E. HARNSBER GER, residing at Staunton, in the county of Augusta and State of Virginia, have invented certain new and useful Improvements in Type-\Vriting Machines,of which the following is a specification.

My invention relates to that class of writing-machines in which a type-wheel is employed which is connected with a rotary shaft operated by a suitable lever or levers.

Myinvention has for its object to provide a machine of this character in which a typewheel is loosely mounted on a supportingshaft, which is operated by suitable inter mediate gears engaging said wheel and a rock-shaft suitably mounted in the frame of the machine, said shaft being operated by a series of key-levers arranged to extend to the front of the machine and arranged as a keyboard, in a manner similar to the key-boards of machines now in use.

It has also for its object to provide forsuitable connections between said lever and the rock-shaft, whereby an approximately equal depression of the type-keys will tend to rotate the said shaft to different degrees, whereby the type-wheel will be moved so as to bring the desired letter or character in position for printing, in a manner hereinafter fully set forth.

It has also for its object to provide a machine which in form will be compact but yet of such a size as to conveniently admit of a double set of key-levers and two type-wheels which operate independent of each other but in a similar manner, one of said wheels operatin g to printthe letters and characters, While the other wheel is provided with a type-surface formed of twenty-six (more or less) of the most prominent words usedc. g., the, and, can, have, for, the.

Finally, my invention has for its object to provide a machine which may be easy to manipulate, which can be constructed at a cost much less than that of the machines now most commonly used, which presents a keyboard easily comprehended and simple in arrangement, and which will act to operate the type-wheels and spacing devices in a simple and effective manner.

and particularlypointed out in the claims, 7

reference being had to the accompanying drawings, in which Figure 1 is a plan View of my improved writing-machine. Fig. 2 is a vertical transverse section of the same, taken on the line 2 2, Fig. 1, looking in the direction of the arrow. Fig. 3 is a detail plan view of the central portion of the machine, showing more clearly the arrangement of the type-wheels, type-levers, rotary shaft, and the adjacent parts. Fig. 4 is a detail view illustrating the pivotal arrangement of the last type-lever and its connection with the rotary shaft. Fig. 5 is a similar view of the first type-lever and its connection with the rotary shaft. Figs. 6, 7, 8, and 9 are detail views illustrating the mechanism for operating the carriage-mover or spacer-wheel and the ribbon -shaft, all of which will hereinafter be specifically referred to. Fig. 10 is a detail view of the bed or pa per-supporting plate. Figs. 11, 12, and 13 are detail views of the tripping mechanism for operating the impression-bar,which will be hereinafter specifically referred to. Fig. 14 is a detail cross-section of the type-wheels and their supporting-shaft, taken on the line 14 14, Fig. 3. Fig. 15 is a detail perspective View of the carriage-frame. Fig. 16 is an inverted plan view of the bed-plate with the detachable inking-rollers in position, and Figs. 17, 18, and 19 are detail views hereinafter referred to.

Referring to the accompanying drawings, the letter A indicates a suitably-constructed frame or casing, the front or key-board portion of which is covered, as at a, while the rear portion is open at the top, as shown, but

closed at the bottom, as at a, to form a support for the type-wheels and bed-plate. In the vertical standards a a secured to the bottom a, I support a fixedshaft B, formed of two sections 1) b, as most clearly shown in Fig. 14: of the drawings. Upon the section b is loosely mounted the word type-wheel O,

while the letter and character wheelD is sup-1 ported to slide laterally on the adjacent ends of the sections 7) b, as shown, the object of having a lateral movement for the letter and character wheel appearing farther on.

The wheels C and D are each provided on their periphery, preferably upon the upper rear face, with a lateral flanged portion 0 D, upon which are secured segmental type-sections C D", as shown. The word-wheel typesection is provided with a series of equidistantlyarranged words, preferably twentysix of the words most commonly used, such as the, and, have, thcmj the, such words being of not more than four letters. The type-section D" is provided with a series of letters and characters, which are arranged in the same longitudinal alignment with the words on the wordwvheel, said letters and characters being arranged in the manner most clearly shown in Fig. 3, from which it will be seen that I arrange the series in parallel rows, with the capitals adjacent the word-wheel, the small letters next the capitals, and the characters and numerals next the small letters.

As before stated, I arrange the type-wheel D so it can be moved laterally. The object of this is to bring either of the circumferential rows of letters or characters in line with the impression-opening X in the bed-plate of the machine. To this end I provide the wheel D with hub portion (1, provided with an extension, as d, the hub portion proper fitting on the end of the shaft-section I), while the extension ('6' is supported on the shaftsection b, as shown.

It will be seen by reference to Fig. ll of the drawings that the distance between the wheel D and the support a is such as to admitof the wheel D being moved toward the wheel 0 a distance equal to the distance between the row of capital letters and the characters, thus admitting of either of the circumferential row of letters or the characters being brought in alignment with the opening X. To provide a simple means for operating the wheel to shift the same as occasion may requi1'e,I arrange a shifting-lever E, pivoted at c to the rear wall (t of the case to swing horizontally, and provide same with a collar portion e, provided with elongated slots 0 e to receive projecting studs di tl projecting from the hub portion (1'.

The forward end of thelever E extends through the slot 1 in the front wall a of the machine and is provided with a spring-stop E, secured upon its upper face, its end having a suitable knob c, upon which for convenience the word Shifter maybe printed or impressed. The slot 1 is formed with notches 2 3 4-, into any one of which the spring-stop may be held when the shifter is adjusted as desired. It will thus be seen by reference to Fig. 17' that should the capitals be in position for printing the stop E would engage the notch 2, and when the small letters are in position it would engage the notch 23, and when the characters are in position it would engage the notch i.

As before stated, I arrange the type-segments upon the upper rear faces of the wheels C D, said segments extending preferably about one-third the circumference of said wheel.

It will be observed by reference to Fig. 2 that the twenty-six words or letters are disposed equidistantly apart, and that to bring the upper or first letter or word into position beneath the opening X the minimum rotation of the wheel will be necessary, while the maximum movement of the wheel will be required if the last word or letter is moved .in position beneath the opening X, said movement being twenty-six times the distance of the first movement.

As the means employed for obtaining the movement of the word-wheel are the same as that for the letter-wheel, I shall describe the means for moving the letter-wheel and shall apply the letters of reference used in designating said means to the similar parts for operating the word-wheel in the drawings. As before stated, I rotate said type-Wheel C to the various movements necessary by means of a rotatable shaft operated by a series of keydevers having approximately the same movement of depression. For this purpose I employ a rock-shaft F, journaled at its inner end in a standardf, its outer end being journaled atf in the casing, as shown in Fi 1 of the drawings. In practical construction I shall connect said shaft with the key-levers G by means of the movable arms II, loosely journaled on the shaft F, and connect said arms II with the levers G- by the connecting- "rods I in such a manner that the greatest movement of said shaft will be but about one fifth of a revolution, the differences between the movement of each key-lever and its adjacent lever being of a degree equal to one twentysixth of the one-fifth movement of the shaft F.

Figs. 4: and 5 of the drawings represent diagrams illustrating the manner in which the key-levers com mu nicate the desired movement to the shaft F. For illustration I have shown the first key-lever and the last keylever, the comparative relation of the series of levers being most clearly shown in Fig. 1 of the drawings.

In Fig. 5 it will be seen that the arm II, which is loosely journaled at its rear end on the shaft F, has its front end extended some distance forward, while in Fig. at the said arm is very short, and in Fig. 1 it will be seen that the remaining arms successively decrease in length from the first to the last arm, said variations of length being so regulated as to cause the second arm to move two degrees of movement, the fifth five, and the twenty-fifth twenty-five degrees.

Between each of the arms II, I provide the shaft F with a series of projections arranged revolution.

in different planes on the front face of the shaft, said projections being so disposed on the shaft to project therefrom at twenty-six different radii, said radii being embraced in about one-fifth of the circumference of said shaft. I prefer to construct said projections by providing a series of collars .1, one next each arm H, fixedly secured to the shaft F, the forward peripheral faces of which are provided with projections J, said projections being arranged to project from the shaft in the manner heretofore described.

By reference to Figs i and 5 the construction and operation of the lever-connections between the key-levers and the shaft F will be readily understood. The first key-lever G, Fig. 5, which is journaled on the shaft K, (upon which all the keylevers are jonrnaled,) is provided with a short rear arm or exterision G, connected with the forward end of the longest arm H, the rear end of which is provided with a lateral lug 7b, which engages the projecting lipj on the collar J.

In Fig. 5 I have illustrated by dotted lines the various radii on which the series of projectionsj are disposed. It will be seen that the projection j, which the first arm H engages, is on radius No.1. Now when the keylever G, connected to said arm, is depressed the projection It will engage projectionj and move it up to the dotted radius marked 0, thus rotating the shaft one degree of its entire movement, which entire movement, as before stated, is but one-third of a complete Now should the fifth lever be depressed its connection with the shaft is such that the lug h on its respective arm H, which is arranged to be in-contact with the projection j on the adjacent collar J, said projection being on radius No.5, will rotate said shaft until the projection j reaches radius 0, and thus rotate the shaft five degrees of its entire movement.

It will be seen (referring to Fig. 4:) that the last key-lever G has its extension G extended a considerable distance to the rear, being connected to the shortest arm H, thereby affording the maximum movement to the shaft when the lever G is depressedi. e., the projection j is on radius No. 26, and when lever G is operated it is moved to radius marked 0, thereby rotating the shaft the entire twentysix degrees, the varied movements of said shaft being communicated to the type-wheel in a manner presently explained. As before stated, all of aforesaid movements of the shaft are accomplished by approximately the same movement of depression on the key-levers. The depression would be of exactly the same degree were all the finger-pieces of the levers in the same plane.

I find that for practical purposes it is very desirable to have a key-board where the keys are arranged in steps and in a compact form.

To this end I arrange my keys in a series of three steps, every third key being a long key, the second an intermediate, and the third a short key. To admit of this construction of key-board and yetobtain the same movement of the rear ends of thekey-levers, Iarrange a longitudinal abutting-board L, disposed below the forward ends of the key-levers, and incline the same on plane extending from a point indicated by the lowest movement of the bottom of the longest key-lever and parallel with its lower edge when in its depressed position, as clearly shown in Figs. 4 and 5. By this arrangement I get the proper throw to the rear end of the several levers, although the upper and middle rows of keys are not depressed quite as far as the lowermost rows of keys.

Upon the inner end of the shaft F is mountedto turn therewith a wheel or segment M, provided on its lower front peripheral face with a series of cog-teeth m, extending over about one-fifth of the periphery, the first tooth m of which normally engages the teeth a of a series of teeth a, formed 011 the periphery of a disk N, secured upon the typewheel D, as shown.

It will be understood that the teeth m and n are of the same size and that the disk N is of such a size that the said teeth 71 extend over one-third the peripheral face of said disk if the type-section extends the same distance on the type-wheel periphery. This construction is essential, so that a maximum movement of the wheel M will turn the disk N and the type-wheel its greatest throw. It will thus be seen that should the shaft F be turned by means of the proper key-lever to five degrees of its movement it would, through its wheel M and the disk N, turn the typewheel until the fifth letter on the wheel would be in proper position beneath the opening X in the bed-plate. It will also be observed that by this construction the typewhcel will be turned so as to bring the last letter or any of the intermediate letters into proper position in the same time it takes to move the first letter into position.

To prevent the type-wh eel being thrown too far forward at each depression of the typelevers, I employ a stop-pawl P, which operates to enter any of a series of notches 0 formed on the front peripheral face of the type-wheel D. These notches are twentysix in number and are arranged one for each letter and at the same distance apart as said letters.

The pawl P is operated so as to enter the proper not-chto hold the wheel from further forward movement when the desired letter is under the opening X in the bed-plate-as, for instance, should the fifth key-lever be operated the wheel will be turned to bring the fifth letter into position and the pawl P will enter the fifth notch c and hold the wheel from further forward movement.

The pawl P is so adjusted that its movement for engagement with the notches occupies the same time that it takes to move the wheel forward the desired distance-t. 6., the

time of the movement of the wheel being the same if either the first or last letter is turned in place-and that the time of movement of the pawl is always the same, so the wheel will be turned with the proper notch in position before the pawl will engage same.

In the practical construction 1 form the pawl of a spring-actuated arm pivoted at p to a vertical standard Q and provide the lower end with a cross-piece p of a width suflicient to engage either of the type-wheels. To form a convenient means for operating said pawl and to obtain the same movement therefor from all of the key-levers, I provide the same with a forwardly-extending arm P, to which is pivoted the lower end of a connecting-rod R, the upper end of which is pivotally connected to the rearwardly-extending arm 8 of a collar S, fixedly secured upon a longitudinal shaft '1, journaled in and extending across the machine, as shown. Upon this shaft are loosely journaled a series of forwardly-extending arms U, (one for each key-lever) of equal length, to the outer ends of which are secured the upper ends of connecting-rods V, the lower ends of which are connected to the key-levers G, as shown. Between each of the armsU is fixedly secured upon the shaft T a series of washers \V, provided with projecting lugs w, which engage lateral projections it upon the arms U, as clearly shown in Fig. 13 of the drawings. By this construction it will be seen that if any one of the key-levers G is operated it will raise the arm U upward and cause its lug u to engage the washer V and cause it to partially rotate the shaft T, which in its movement will cause the arm .9 to depress the end I of the pawl P and raise its lower end 19 into engagement with the type-wheel, for a purpose before stated.

Y indicates the carriage-frame, (shown in detail in Fig. 15,) which consists of a rectangular frame provided on its front bar with a spacing rack-bar 11 a pointer y, and a lifter-piece p while its end pieces are provided with extensions y, to which are secured the travelers or rollers 31 p. \Vhen adjusted in operative position, the rollers y 11 are supported on a track-bar Z, secured across the rear part of the machin e, as most clearly shown in Fig. 2 of the drawings, while its front portion is supported upon a toothed wheel 10, mounted upon a shaft 11, and a roller 12, journaled on a shaft 13, its pointer y traversing the front edge a of the casing when said edge is provided with the usual space-scale.

The toothed wheel 10, which I will term the spacer-wheel, is provided with any desired number of teeth, depending upon the length of the line of print for which the machine may be constructed. The shaft 11, upon which said wheel is journaled to turn therewith, is mounted in standards 14 14, secured to the base, the upper ends of which, in connection with standards 15 15, form the sup ports for the bed-plate X, hereinafter referred to.

Upon the shafts 11 and 13, between the standards 14. 15, are fixed the ribbon-spools 7o 16 16*, upon which the ribbon 17 is wound, the ends thereof being connected to said spools in the usual manner, said ribbon being passed between the type-wheels and the bedplate, as clearly shown in Fig. 2 of the drawings.

To obtain a continuous movement in one direction of the spacer-wheel from the partial movements of the shaft T, I employ the construction most clearly illustrated in Figs. 6, 7, 8o

8, and 9 of the drawings, by reference to which it will be seen that near the end of the shaft 11 I fixedly secure a ratchet-wheel 18, which is engaged by a spring-pawl 19,secured upon a hub 20, loosely mounted upon the end of rotation of the shaft T will cause the pawl 19 to turn the shaft 10, so as to move the spacerwhecl one tooth, and thereby feed the carriage one space, an d as the shaft '1 resumes its nor mal position it will carry the loose hub 20 and pawl 21. back to their normal position. 5

The pawl 19 is provided with an extension or handle portion 23, so it may be lifted from the wheel 18 when it is desired to wind up the ribbon on the spool 16 after it has been wound up on the spool 16, the shaft 13 being too provided with a suitable crank-handle 24, ex-- tended to without the front of the machine, as shown in Fig. 2.

The bed-plate 'X',before referred to, which is shown in detail in Figs. 10 and 10, consists of a sheet-metal plate secured upon the upper ends of the standards 14 15, the front and rear ends being curved down, as shown, to admit of the easy movement of the paper.

The central portion of the plate X is cut out, I to as at 00, said portion being covered by a flexible material, such as elastic cloth 25, provided with the opening X for the letter or characters and an elongated opening X arranged in the same alignment, which forms 1 15 the impression-opening for the word-wheel.

Should a letter, as B, follow the word them, the capital letters being in line for operation, it would be about two spaces away from the preceding word, thereby making the I 20 operation of the spacer at this time unnecessary.

In the practical arrangement of my machine I construct it with detachable inkingrollers 30 of usual construction, which are journaled to the bed-plate X below the outer ends thereof, as clearly shown in Fig.1(5. To admit of the ready detachment of said rollers, I provide brackets 31 31, in which are journaled the ends 32 of the roller-shafts, the op- 1 o posite ends being bent to form eyes 34, through which the securing-screws 35 are most'clearly illustrated in Figs. 1 and 2 of the drawings, and which consists of a horizontal portion 37, extended transversely over the central portion of the machine, which is 4 provided with a rearwardly and downwardly extended portion 38, secured to a short rock- -shaft 39, journaled to the rear wall of the casing, as shown. It is also formed with a depending arm 40, having lateral wings 41, which extend over the openings X X flbeing normally held just out of contact with the type-wheel. The outer end of the arm 36 extends through a keeper 42, secured upon the upper end of the standard,the lower portion of said keeper being formed by a transverse bar 43, which is formed with anextended portion 44, for a purpose presently explained. The end of the arm is normally held from its rest on the bar 43 by the spring 45, (see Fig. 12,) one end of which is secured to the upper end of the standard, while its lower end is connected to a swinging arm 46, pivoted at its rear end to the inner rear end of the extension 44.

To the outer end of the arm 36 I pivotally secure the upper end of a rod 46, the lower end of which extends within the casing and is connected to a rearward extension 47 of a disk 48, fixedly secured upon the shaft T. By this construction it will be observed that where any one of the key-levers is depressed atthe moment the type -wheel is brought into the desired position the disk 48 will be moved by the shaft T, and the rod 46 will force the end of the arm 36 down and cause its winged portion 41 to press the paper against the type, and thereby cause an impression thereof on the paper.

Then I employ the inked ribbon, I dispense with the inking-rollers and the direct connection between the arm 36 and the shaft T and make an indirect connection therewith, as most clearly shown in Figs. 11 and 12 of the drawings. In this instance I employ a tilting arm 49, pivoted to the outer rear end of the extension 44, and connect the rear end 50 of said arm to the shaft T by means of a rod 51, connected to the projection 52- of the disk 53, secured to the shaft T, as clearly shown in Fig. 3. In the forward end of the arm 49 I pivot a gravity -tripper 54, which normally engages the lower edge of the outer end of the arm 36. By the aforesaid construction it willbe seen that when the keys are operated, as before stated, the shaft T will cause the rod 51 to throw the front end of the arm 49 upward. The tripper 54, raising the arm 36 and slipping the same, allows it (the arm 36) to fall by gravity, its weight slightly overcoming the tension of the spring 45, and cause its wings to make the impression on the paper by pressing the same against the type-wheel.

It will be understood that the portion of the bed-plate which has the impression openings X X being flexible, permits of the pressure of the wings 38 against the type, as described.

The paper-feedingdeviees, which are clearly illustrated in Figs. 1 and 2, consist of upwardly-extending arms 55, in which are journaled one above the other the elastic-covered rollers 56 56, which have'a frictional bearing with each other. The shaft 56 of one of the rollers 56 is extended and provided with a ratchet-wheel 57, which is engaged by apawl 58, operated by pivoted arm 59, to the rear end of which the pawl 58 is pivoted in the ordinary manner, said arm having ahandle extending to within convenient reach of the operator. Secured upon the front edges of the arms 55 is a guide-plate 59, which extends entirely across the carriage, as shown, the forward end of which extends over the bed-plate near the rear wall of the openings X X to hold the paper in proper position over said openings. To the rear edge of the standard I secure a curvedpaper-guide 60, which serves to roll up the paper as it is fed from the feedrollers and hold same from coming in contact with carriage-supports.

In the front portion of the machine, below the spacerwheel, I journal a rock-shaft 61, which I term the spacer-shaft, to which I fixedly connect two key-levers 62 63, one of which Iterm the word-spacer and the other the letter-spacer. Upon thespacer-shaft I secure one end of a rearwardly-cxtending arm 64, provided with an upwardly-extending slightly-flexible finger 65, which is guided in a suitable keeper 66, as most clearly illustrated in Fig. 7 of the drawings. The upper end of the finger 65 is provided with a seat 68, in which normally rests one of a series of rearwardly-projecting teeth 69, arranged in a circle near the rear peripheral face of the spacerwheel, said teeth being of the same number as the notches in the periphery of the spacerwheel and indicating a distance of one space between each tooth. To normally hold the finger 65 in its proper position, I employ a spring 70, as shown in Fig. 7, the upper end of which moves in an elongated slot 71 of the keeper.

It will be understood that when itis desired to print a word such as you or them, moving the carriage and paper a single space will not bring the paper in the proper position, and that the carriage would have to be moved a distance of at least six or seven spaces. For this purpose I arrange the wordspacer in such a manner that in case the word them should follow the word you by depressing the word-spacer the carriage and paper will be moved forward the desired distance. Should, however, the words for or them follow the word it, the operator moves the carriage two or three spaces with the letter-spacer, and then by depressing the word-spacer one time will bring the carriage and the paper in the proper position.

To regulatothemovement of the spacer-keys, I arrange them to strike an abutment which consists of a plate or bar 7;, provided with depressed portions 7 3 74-, the portion 75 being so disposed below the letter-spacing key to admit of said hey turning the spacer-shaft to move the spacer-wheel one tooth, while the depression 74, which forms the abutment for the wordspacing lever, will admit of said lever turning the shaft. to operate the spacerwhcel four spaces.

13y reference to Fig. 1 it will be observed that I arrange the spacer-keys and the shiftinglever centrally of the key-board and above the other lays, so as to make their arrangement conspicuous.

By arranging the letter and character wheel in the manner before described and employing a shifter, as stated, I am enabled to use on one type-wheel three kinds of letters or characters and operate same by one set of key-levers, the arrangement of such letters and characters being clearly understood by reference to the drawings. It will also be understood that any well-known mechanism maybe employed to bring the type-wheels back to their normal positions; but- I prefer to make the shafts F, which operate said wheel, spring'actuatcd by employing a volute spring 80, as shown in Fig. 10.
