TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 477,165, dated June 14, 1892.

Application filed April 11, 1891. Serial No. 388,51 2. (No model.)

To all whom, it may concern:

Be it. known that we, WILLIAM J. ISORDEN, of Hice, in the county of Hamilton, and JAHU YV. JOHNSON, of Houston, in the county of Harris, State of Texas, have invented a new and useful Improvement in 'lype-IVriters, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in typewriting machines, and has for its object to provide a machine of simple and durable construction, capable of use for the ordinary purposes to which type-writers are applied, but especially adapted and designed for typewriting upon blank books, thereby facilitating the making of official records and produc-` ing records that are more legible and compact than it is possible to obtain by handwriting.

The invention consists in the novel construction and combination of the several parts, as vwill be hereinafter fully set forth,

and pointed out in the claims.

Referenceisto be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure l is central vertical section through the machine. Figi? is a front elevation of the machine, a portion of the keyboard and the upper portion of the machine, including the type-wheel, being in section. Fig. is a detail View of the vertical adjusting mechanism of the carriage. Fig. 4- is a plan View of the machine,the type-wheel being in hori- Zentral section and a portionof the main frame being broken away. Fig. 5 is a horizontal section through the machine, taken just above the keyboard; and Figs. (i and 7 are views illustrating a construction of type-wheel differing from that shown in the other figures.

The base IO is preferably made rectangular, its upper front surface being beveled downward, and a stationary frame is secured to the base, comprising two nprights l1, at taehed to the right and left sides of the base near the rear, the said uprights being preferably rectangular in cross-section and connect-ed at their upper ends by a cross-bar 12. Two guide-standards I3 are secured to the base in like manner to the uprights, but. nearer the front. Above the base the standards are circular in cross-section, and their upper extremities are connected with the cross-bar 12 byside bars 1i. lVithin the 55 frame, secu red to the base, a carriage A is capable of vertical movement, the said carriage being adapted to support the type-wheel and its appurtenances and also an oscillating frame I3, in which the shaft of the type-wheel 6c is mounted. The oscillating frame comprises two angle or elbow side sections l5, one being journaled in each side of the carriage near its rea r upon stud-axles l lG, entendinghorizontally inward from the side bars of the carriage. In bearings formed upon the vertical members of the side sections the extremities of the driveshaft 17 or the type-Wheel 1S are journalcd, and the horizontal members of the sections are united by a rod or bar lf). The 7o right-hand elbow-section has secured to its outer face an angle extension 20, the horizontal member whereof extends outward below the side of the carriage, and an arm 20" of similar shape is loosely mounted upon the left-hand stud-axle, while in the extremities of the horizontal members of the extension and arm horizontal forks 2l and 2l are swivcled.

The arm 20"* at the left of the oscillating So frame has connected therewith an upwardlyextending segmental rack 22, engaging with a pinion 23, secured to the type-wheel shaft. The object of the oscillating frame is to carry the type-wheel to and from the surface to be printed upon. Instead of connecting the parts comprising the sides of the oscillating frame and mounting said sides to rock upon fixed stud-axles, the axles may be rigidly secured to the sides of the oscillating frame and 9o mounted to turn in the carriage.

rIhe type-wheel shaft is provided with a longitudinal groove and the hub of the typewheel has akeyto [it in the groove. The preferred construction of the type-wheel consists in forming the same with an annular fiange 2i upon one side, as shown in Fig. 4, and short type-bars 25 are pivot-ed in a diametrical line upon the circumference of the wheel or at a right angle to it. The circumloo ferential face of the wheel is beveled and provided with lugs 2G, pins or their equivalents constituting fulcruins for the type-bars. The type-bars extend horizontally over and beyond the flanged side of the wheel, and their under edges are provided with two beveled surfaces a and d', extending upwardly and outwardly in opposite directions, the outer or upper edges of the bars at the ends projecting over the flange of the wheel being provided with offsets d2, upon which offsets the type is produced. Each type-bar is con neeted YwithY the wheel-flange by a spring 27.V Y

The carriage is guided in its vertical movement by affixing to its sides vertical plates 28, provided with sleeves 29, which slide upon the standards 13.

Each side bar 14 of the main frame has pivoted thereto between the standards and uprights ll and 13 an outwardly-extendinghorizontal arm 30, the pivotal connection being effected between the inner ends of the arms and the upper or under faces of the side bars, and some distance below the arms segmental racks 3l and 32 are pivoted in the base, one at each side, the toothed surfaces of the racks being within the base. The outer ends of the racks 3l and 32 are connected by rods 33 and 34 with the pivoted arms 30, and the said rods pass between the swiveled forks 2l and 2ln of the oscillating frame B.

The key-levers 35 are fulcrumed at their rear ends in the base of the machine, and near their fulcrums rest upon springs 36 of any approved construction. The Vforward ends of the key-levers are bent downward and upward and are provided with the usual form of key. The key-levers rest normally upon a crank-shaft 37, journaled upon suitable bearings, preferably projecting from the inner side surfaces of the base, the central crank-arm 37 of the shaft being normally held horizontal and essentially parallel with the front of the machine by springs 38, attached to the base and the shaft near its eX- tremities.

The eraiik-shaft at the right-hand side of the central crank-arm is provided with a downwardly extending section having a straight rack-surface 30, adapted to engage with the right-hand segmental rack 32. By this arragement whenever a key-lever is pressed downward it engages with the central crankarm of the crank-shaft and carries the shaft in the same direction, and the rocking movement of the shaft, through the medium of the racks 32 and 39 and their connections with the oscillating frame, causes the lat-ter to rock rearward and carry the type-wheel in the direetion of the page to be written upon, and the pinion 23 of the type-wheel shaft moving upon the segmental rack 22, mounted on the frame B, which is stationary at this moment, revolves the typewheel sufciently to present the proper type to the page. The rotation of the type-wheel is stopped by causing the segmental rack of the oscillating frame B to move with the frame, and this is accomplished by the downward movement of the key-levers also, as said levers after engaging with the crank-shaft engage with pins 40, graduated in height and preferably attached to avpivoted crank-lever 4l, located in advance of the crank-shaft and beneath the normal plane of the latter, as is best shown in Fig. 5.

The crank-lever consists of a bod y-section made in two sections b and b', the upperseetion being adapted to slide upon the lower section.

The graduated pins 40 are located upon the sliding section and the lower bodysection has secured to each end a rearwardlyextending bar or plate b2, the said bars being pivoted to the side pieces of the base, preferably below the journals of the crank-shaft 37. Each bar orplate b2 is normally pressed by v a spring 42, located near the springs bearing upon the crank-shaft, as is best shown in Fig.

` 5, and upon the left-hand bar or plate b2 a downwardly-eXtending lug is formed having a straight rack-surface 43 engaging with the segmental rack 3l. Instead of using the pins 40, screws may be employed-in fact are preferred, being more readily adjustable. The sliding section of the crank-lever, having the `pins or screws attached, may be shifted to the right or to the left by means of a lever 44, which is illustrated in Fig. 5 as engaged by a keeper 45, which may be of any approved construction, and is adapted toY lock the lever in a predetermined position. The keeper is represented as comprising a rod journaled in one side of the base, jaws carried by the rod, and a handle or button by means of which the rod is turned.

By shifting the lever 44 different sets of pins or screws are brought beneath the keylevers, enabling one key-lever to control, for instance, three styles 'of type, all the styles being arranged upon the type-wheel. The machine may be built either with or without shifts to suit purchasers.

The spacing-lever 46 does not when pressed impinge upon a screw orpin 40, but is adapted, primarily, for engagement with the crankarm 37n of the crank-shaft 33, whereby the frame B is moved in direction of the page to be printed, carrying with it the type-wheel, which wheel is revolved while being moved forward. As the frame-segment is stationary when the spacing-lever is pressed down to its full extent, the type-wheel will not have engaged with the page to be printed, since the spacing-lever does not move the crankshaft as great a distance as the key-levers, the snrface of the spacing-lever engaging with the crank-shaft being concaved, as shown at b3 in Fig. l.

From each forward end of the carriage A avertical bracket 47 is projected, and in the IYOO IOS

IIO

said brackets the ends of a tube Lf8 are secured, the said tube being provided in its under side with a longitudinal slot 49. Upon the carriage tube 48 a sleeve 50 is held to slide, having a spur 5l projected downward from its inner face, and a finger 52, longer than the spur, projected from its outer face. The sleeve 50 controls the lateral movement of the type-wheel, being provided with two rearwardly-eXtending horizontal arms 53, one located at eachy side, which arms project over the type-wheel shaft in engagement with the hub ofthe Wheel. One arm is shorter than the other, and the longerarm atits extremity has secured therein apin 54, extendingin direction of the peripheryof the type-wheel, as shown in Fig. et, being adapted for engagement with the pivotcd type, and acts to force the type in engagement with the surface to be printed.

lVithin the tube 48 a spring 55 is concealed, the said spring being usually a coil or spiral one, as shown in Fig. 2. One end ot' the spring projects downward through the slot in the tube 48, and is secured to the sleeve 50, and the opposite end is attached toa stud 5G, forming a portion of a worm-wheel 57, located at the right-hand end of the tube, and meshing with a short. worm-shaft 58, manipulated through the medium of a disk or thumbwheel 59 at the front of the carriage. The worm shaft and wheel are adapted to impart more or less tension to the spring VThe type-wheel-actuating arms are not perfectly straight, but midway of their length are pro vided with downwardly and rearwardly beveled shoulders GO, as shown in Fig. l, for a purpose set forth in the operation, and also with stirrups 60, extending below the hub of the wheel, as also shown in Fig. l. The spring 55 causes the sleeve when not held in a fixed position to move from left to right, carrying "the typewheel in the same direction. The sleeve cannot move until after a letter has been printed or the space-key has been depressed, its movement being controlled by a spacing mechanism. rlhis mechanism consists of a rack (il, journaled at its ends in the sides of thecarriage and connected at one end with the oscillating frame B by a link 62, or its equivalent. The rack when rocked by the oscillating frame is adapted for engagement with the spur 5l ot' the sleeve and a spring-pressed tooth G3, pivoted upon the rear face ot' the spur 5l. The tooth 63 is fast upon a spindle pivotcd in and extending through the carriage sleeve, and upon the outer end of the spindle a lever (Si is secured. The tooth is pressed by a spring G5 above its fulcrum, as shown in Fig. 2, and the distance that the sleeve shall move when the rack is disengaged from the tooth is regulated by a cam-faced or eccentric button (ifi, which impinges upon the upper portion ofthe tooth and is manipulated through a spindle, to which the button is attached, and a crank 67, or its equivalent, secured to the forward end of the spindle.

Then the frame B oscillates, the rack is so rocked as to release the tooth G3 and again engage with it. As soon as the tooth is disengaged froin the rack it is moved by its spring the distance of one or two teeth in the rack, according as it has been set to move by the cam-faced or eccentric button GG, as it is understood that the tooth will move different distances, according to the face of the eccentric with which it is brought in contact. By

forcing the lever (it, connected with the tooth,

to the right the tooth can be made to disengage from the rack at any time-as for instance, when it is desirable to move the sleeve, and consequently the type-wheel, quickly from left to right. The sleeve can be moved from right to left by simply pressing the sleeve-linger 52 to the left, as the tooth will ride over the rack.

Upon the front of the carriage A two stopslides G8 and 69 are located, adapted to check the movement of the sleeve at any desired point either to the right or to the left. A bar 70, upon which is marked the letterscale, is loosely mounted in the slide 68 and is secured tothe slide G9. The slide 68 can be moved on the bar 70 to space the width of the page to be operated upon and determine the length of the lines to be printed, whereupon this slide is secured to the bar 70 after adjustment by means of a set-screw 7l, or its equivalent. The slide GQ is also provided with a corresponding fastening device, which main tains it at any desired point upon the face of the carriage. The set-screw of the slide G9 being released and that of the slide 68 set, both slides are free to move together.

The spacing mechanism heretofore described regulates the distance laterally between the letters and the words. Another mechanism is employed for spacing between the lines and for making insertions between the lines. This latter mechanism consists of a vertical rack-bar 7i, located at the left side of the machine, the upper end whereof is journaled in the left top bar 14; of the main frame, the lower end being passed through a guidecollar 75, attached to the base and journaled in one of a series of apertures 7G of different depths, produced in the periphery of a disk 77, pivoted tothe side of the base and having a handle 78 attached. The object of thus journaling the lower end of the vertical rack is to enable the operator by changing the socket of the rack to raise or lower the carriage A for the purpose of intcrlining above or below the line being printed, which is especially useful in making fractions or for inserting omitted words.

The vertical rack is engaged by two teeth 79 and 80. The tooth 79 is located at the lefthand side of the carriage at the front and is, essentially, L-shaped. The rackengaging IOC IIO

member is preferably beveled rearwardand extends horizontally at a right angle from the carriage, the shank member being pivoted to the carriage, and the tooth is normally supported in its normal position (shown in Fig. 3) v The rack-engaging member of the tooth 79 is depressed to permit the carriage to drop the distance of one or more teeth of the rack by a regulating-disk 82, pivoted to the carriage and provided with marginal or peripheral spurs 88 of different lengths, which spurs are brought in engagement, as required, with the rack-engaging member of the tooth, as illustrated in Fig. 3. The tooth 80 is located parallel with the inner front surface of the carriage and the extremities of the tooth project through openings in the sides of the carriage. tremi-ty is free to be raised or lowered and engages with the rack, and at the right-hand extremity the tooth is pivoted to the upper end of a spring-pressed lever 85, fulcrnmed at or near its center in any approved manner to the carriage. The rack near its lower end, within convenient reach of the operator, is provided with a horizontal handle Il.

In operation when the handle Il is moved tok the left the tooth 80 is released and allowed to fall and the rack engages with the tooth 79, thus supporting the carriage; but upon returning the handle to the right the rack again engages with the tooth 80, the weight of the carriage causing it to descend the distance of one,two,or three teeth in the rack, according as has been predetermined by the regulatingdisk 82. By means of the lever S5 the carriage can be released to be raised or lowered at will, as by pressing inward the lower end of the lever the tooth SO is disengaged from the rack and the carriage is free to be moved up or down.

An inking-roller 87 is located immediately below the type-wheel, which may consist of cork or other substance covered by an inking-pad, as shown in Fig. l. The axes of this roller are in horizontal alignment with those of the oscillating Vframe B. This arrangement is made in order that all of the type may be brought in contact with the inking-roller at each revolution of the type-wheel. All of the type are inked every time the space-key is depressed and all will be frequently brought in contact with the ink-roller in the course of printing words.

The inking-roller is support-ed in the following manner: A rock-shaft 8S is journaled in the carriage at the back, from which arms 89 are forwardly projected, and in the forward extremities of the arms the axis of the roller is journaled. The roller is constantly made to bear to a greater or less degree against the type of the type-wheel by manipulating a set-screw 90, located in the lower edge of the carriage at the back to bear more or less against a spring 91, projected vertically downshall be perfectly smooth and to preserve perfect alignment-a thin bar 92 is made to engage with the page, as shown in Fig. 1, longitudinally slotted to permit the passage of the type, the said alignment-bar being rigidly secured to the back of the casing by uprights f 93, or their equivalents. Brackets are secured to the rear of the frame-uprights 11, upon which brackets a table 94 is firmly fastened, adapted to support the book C to be typewritten. 95 is held to slide, and each bar has pivoted p upon its outer end a cleat 9G, the said cleats f being adapted to support that portion of the book not being operated upon.

A. to place against the clamping-bar 97 and the The The book is held firmly uprights 1l by a platen 99, engaging with its back. This platen is pivoted between two arms 100, curved upward from a shaft 101, i journaled in the back of the base of the machine, as shown in Fig. l, which shaft is provided with an arm 102, connected by a pitman 103 with a treadle or its equivalent,

whereby the platen may be pressed with considerable force against the book.

In connection with the treadle any approved form of locking device may be employed.

When small books are to be type-written,

' it is necessary that more force than is obtainable through the treadle should be applied t-o the platen. Therefore a bar lO-tis located between the arms of the book-holder below the fulcrum of the platen, and a setf screw 105 is passed through the bar to an engagement with the platen, as is best shown in Fig. 1.

The machine must be of sufficient strength to accommodate the largest size of books, and while designed especially for books it can be put to all the uses of type-writers in general. The position of the book when held by the platen against the frame is such that it will at all times aiford the operator a plain view of the work, since the printing mechanism will not obscure that portion of the page which has been printed.

In turning leaves the operator has only to release the platen, when it will fall back and constitute an inclined rest for the book,which will afford ample room for turning theleaves. It will not be necessary at any time to remove a book to inspect its contents.

The machine will fulfill all the requirements of type-writers in general and more .i s.. .s Y s .mm u

than any other can accomplish, in that it will enable an operator to type-write upon blank books of any size or description with a facility equal to that obtained by any typo-writer operating on single sheets. Various styles of type can be employed, it being only necessary to remove one type wheel and substitute another. Cone bearings will be employed throughout in the construction of the machine wherever practicable, and metal only will preferably compose its parts.

l The type-wheel shown in Fig. G, and which 1n many cases is preferred, consists of a slidelike hub 106, adapted to slide upon a grooved shaft, which hub is provided at or near its central portion with a perpendicular flange 107, and around the circumference of the ilange a series of delicate springs 10S is fastened, the number of springs being equal to the number of types to be employed, each type being provided with a spring. These springs stand at right angles to the flange projecting on both sides.

The springs and theinner ends of the typebars 109, lwhich rest upon and are attached to the springs, occupy the circular space between the flange and the circumferential face 110 of the wheel. The face of the wheel is supported by spokes lll, connecting with the hub at both sides of the flange, which spokes have sufficient tenuity to allow them to pass between the springs. The type bars are straight and stand radially, extending outward through slots 112 in the face of the wheel.

The outer ends of the type-bars are provided with types set therein and secured thereto in any suitable or approved manner, and the type-bars are somewhat Wider than the types, thus forming on both sides of them shoulders or lugs 113, which are designed to have contact with pins set in the ends of the guidearms 58, and when this form of wheel is employed the guide-arms are of equal length,or practically so. The pins are arranged upon the guidearms so as to point inward, facing each other, and stand at a right angle to the arms. The contact of the pins with the shoulders or type-bars takes place when the wheels are brought in close proximity to the page of the book. The type-bars being free to move in the slots of the wheel, the contact of said bars with the pins upon the guide-arms causes the said bars to recede, compressing their attached springs, and the bars, `on being released from engagement with the pins, are by the reaction of the springs projected outwardly, carrying the types beyond the circumferential line in which they stand when at rest. The chief object of this peculiar construction is to prevent the possibility of more than one type at a time coming in contact with the page, for the curvature of the wheel, whose diameter could accommodate in a single line seventy-eight or more types, would be so slight as to make it probable that more than one type would impinge upon the page of the book, its surface being a plane.

The type-bars are released in the following manner: The under side of the guide-arm 53 is arch-shaped where the wheel-shaft plays in its oscillation, producing thereby lng-like projections extending downward and with which the shaft comes in contact, thus raising the guide-arm slightly and releasing the types from engagement with the pins on said guidearms. The stirrups on the under sides of the guide-arms serve the dual purpose of preventing the pins rising beyond a predetermined distance and of stopping the type-wheel in its forward motion at the desired point.

It may possibly appear that if the typewheel is mounted in the frame B and swings with said frame its pinion would not move properly over the rack Such is not the case, however, as the rack 22 is held stationary by reason of its connection with the crankshaft carrying the graduated pins or screws until caused to move by a depressed key-lever coming in contact with its corresponding pin on the crank-shaft, and the rack 22 being thus held stationary the forward movement of the frame B will cause the pinion to move over the rack rotating the type-wheel shaft, and consequently the type-wheel.

In Fig. 7 we have illustrated a slight modification in the construction of the type-wheel, in which the type-bars llt are essentially angular or L-shaped in general contour, and the bars are fulcrumed upon the inner face ofthe peripheryof the wheel in such manner that the extremity of the horizontal member will extend a slight distance beyond one side face of the wheel, and the vertical member of each type-bar is adapted to extend outward through openings in the circumferential face of the wheel, and the said members of the bars have the types attached thereto. Each typebar is connected with a spring secured to the flange of the wheel-hub in any suitable or approved manner. In the operation of this form of the-wheel the outer ends ofthe type-bars will come in contact with a pin on the righthand guide-arm and, thus being forced inward, will cause the vertical members to be thrown outward, and the printing of a page can in this way be effected. It may be mentioned that the guide-arms can be made to serve as indicaters to facilitate placing the type-wheel in position wherever desired.

Owing to the manner in which the linespacing and the letter-spacing is accomplished we are enabled to employ type of different sizes.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a type-writer, a type-wheel, springpressed type carried by the wheel, an oscillating frame supporting the wheel, an actuating IOO IIO
