TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 419,209, dated January 14, 1890.

Application filed February 6, 1888. Serial No. 263,189. (No model.) Patented in England October 18, 1887, No. 14,180 in Germany No. @3831; in France April 1'7, 1888, No. 190,032; in Belgium No. 81,648, and in Austria-Hungary No. 42,176 and To aZZ whom it may concern:

Be it known that I, FREDERICK MYERS, a citizen of the United States, residing at Liverpool, in the county of Lancaster, England, haveinvented certain new an d useful Improvements in Type-Writing Machines, (which invention has been patented to me in England, No. 14,130, October 18, v1887; Germany, No. 43,831; France, No. 190,032, April 17, 1888; Belgium, No. 81,648, an d in Austria-Hungary, Nos. 42,176 and 6,427, and for which I have obtained provisional protection in England, No. 12,803, dated September 21, 1887,) of which the following is a specification.

The invention relates to a type-writer having the finger-keys arranged in parallel rows and designed so as to produce a strong, simple, and reliable machine at less cost than some that are at present in the market.

In the drawings, Figure 1 is a front elevation of my improved type-writing machine, with part of one of the upright frames in section. Fig. 2 is a cross-section on line mm, Fig. 1, with the paper-carrying roller and its frame removed; Fig. 3, a cross-section on line y y, Fig. 1,showin g the paper-carrying-roller frame and its attachments, and also a device for clipping the paperto the roller, parts of the mechanism being removed for the sake of clearness. Fig. 4 is an end elevation with parts removed; Fig. 5, a plan of the machine; Fig. 6, a back elevation of a small portion of the key-frame, with its handle and connecting-rod for moving it longitudinally and a device for looking it in the required position. Fig. 7 is a device for spacing the lines. Fig. 8 is a plan of a port-ion of the machine, showing more especially the device for spacing the words and letters; Fig. 9, side elevation (enlarged) of a disk with pins and stopping device for engagingthe said pins or projections to adjust the type-wheel forprinting; Fig. 10, an end elevation of Fig. 9, used also as adiagram to show the arrangements of pins in the whole series of disks and the relative positions of the corresponding type on the typewheel; Fig. 11, a detail of paper-gripping device.

A is the frame-work or base of the apparatus, on which are mounted the upright frame B and the standard B.

C is a wheel or disk, on the periphery of which are arranged the letters, numbers, stops, symbols, &c., which are required.

The type-wheel C is mounted 011 a spindle or shaft D, which is journaled at one end to the standard B and at the other to the springbarrel frame B The shaft D is preferably driven by a spring, though other sources of motive power may be employed-such as a small dynamomachine, a descending weight, 650., or even a band driven from a continuously-rotating shaft might be used in conjunction with a suitable friction-clutch.

F is a spring-barrel containing, preferably, a coil or clock spring wound on a spindle or drum F and supported between the checks of the frame B on the shelf f of the upright B. The teeth f of this spring-barrel engage a pinion D 011 the spindle D. F is a handle for winding the spring from time to time as soon as it has spent its force. The spring is prevented from uncoiling when it has been wound (except when released, as will be hereinafter described) by means of the pawl f which engages the ratchetteeth f on one of the cheeks B being a similar arrangement to that used for clocks.

The keys G are arranged in parallel rows in the frame H, transversely of it. The same keys which are used for printing the large characters may also be used for printing the small characters and the figures in the manner hereinafter described. The frame H is mounted on guide-rods E, so as to slide longitudinally, the said rods being secured to the frame B and standard B, or in other convenient manner. Below each transverse row of keys is provided a lover or rod J, which is pivoted to sliding frame H, and upon which the keys G or their spindles rest. This keylever can be depressed by any one of the keys G in the row which rests upon it. It is held in position by means of a spring J, and,

if desired, the keys themselves may be provided with springs. I prefer, however, to provide the levers only with springs, so that all the keys in one row will descend when one key is depressed and thus leave ample space for the hand or fingers of the operator. All the keys are provided with shoulders or stops g, so placed that no two keys in a row will descend the samedistance. For example, the front key may be made to descend a little farther than the second, the second key a little farther than the third, and so on. Disks K are mounted on the spindle D and firmly.

secured thereto, and between each of the said disks K, I mount two other disks K K also firmly secured to the spindle.

The spindle D, with its type-wheel C, is prevented from revolving under the action of the spring in barrel F by the application of a block or cushion L, which engages a wheel M, also attached to the spindle D. In practice this wheel will be preferably made with a toothed or jagged face.

spring hereinafter referred to, or by the weight of the paper-carrying devices and of the other one being described hereinafter.

The other end of the leveris provided with afrod or bar P, placed below the pivoted levers J and parallel to the ends thereof, being made of such a length that any one of the. said key-levers will strike it when depressed, and thereby withdraw the block L fromthe brake-wheel M. The other end of the bar P is attached to a lever 0 also pivoted on the rod 0 and having a rearward.

extension 0 Between 0 and the arm 0 a stay P is rigidly fixed, so. that P, O, 0 P,

0 and 0 move together as one frame abouttheir pivot O.

R is the paper-carrying roller, supported in any convenient manner on the frame R,which slides in a hinged guide or bed S. The end .of. the roller R is provided with a wheel having a number of notches 4", Fig. 7, into which a spring pin or pawl r engages itself, holding the roller in any desired position.

to the distance required between the lines of writing or printing. On the completion of a line-the hand wheel or disk 0*, Fig. l, is turned in the direction of the arrow, Fig. 7. The pawl r is therefore depressed and the paper-roll can be movedthe required distance. The bed S is hinged. or pivoted at s to bed A of the machine and to the frame B, or in other .convenient manner, so that the paper-carryin g. roller R, with its sliding frame and attachments, can be raised on its pivots 5 against the type-wheel 0. That end of the bed S farthest This block is held in engagement with the wheel M by a.

The dis-. .tance between each of the notches r is equal from the type-wheel C and below the lever O is provided with an arm S, which is connected by means of the rod S to the arm 0 of the lever O. The connecting-rod S has at its lower end a longitudinal slot S through which the connecting-pin of the arm S passes and along which it is able to move. The top of this slot rests normally on the said pin and is of such a length that its lower end only engages the pin and raises the paper-carrying roller after a great portion of the upward movement of the rod S and downward movement of a key have been accomplished. The bed S, when at rest, is supported, as shown,

on a pin a, affixed to the machine in A. When any one of the keys is depressed to the full extent of its travehthe paper-carrying roller R will therefore be raised against the typewheel O. The keys G being depressed through varying distances in consequence of the positions of the shoulders g, it follows that the connecting-rod S will have a different amount of upward movement for each longitudinal row of keys. The upward travel of the paper-carrying roller R is, however, constant and must be accomplished by the shortest upward movement of the connecting rod S that is, of the arm S. To allow the said arm to move independently of the bed S during the greater movements of the rod S it is spring-pivoted to S, as shown at s Fig. 2, its spring's keeping the extension or tail 8 normally against thebottom of the bed S. The spring 3 is strong enough to keep the arm S in normal position while the type on wheel O prints the paper on roller R; but any pressure on wheel 0 in excess of what is necessary to print overcomes the resistance of the spring and prevents the type or paper from being injured. The raising of the connecting-rod S causes the roller-frame R to be moved longitudinally the necessary distance for spacing the letters. This may be eflfected by means of a toothed rack T, supported in brackets t,:attached to the hinged bed S and having at its end a pint. The sliding frame R has pivoted to it a pawl which engages the teeth of v the toothed rack T in one direction only. As the connecting-rod S is raised by the depression of a key, the pin S attached thereto raises the rearend of the rocking-lever i which rest-s upon it. The said lever (shown in plan in Fig. 8) is pivoted at t to the frame 13 or other suitable point and carries at its front end an inclined finger or projection t which, when depressed, engages the pin 25 and causes the rack T (and with it the sliding frame R by means of the pawl to be drawn forward the space required for printing one letter. By this time the lower end of the slot S -has engaged thepin of arm S, and the further movement of the rod S raises the said arm, and consequently the paper-carrying roller, a sufficient distance to press the paper thereon against the typewheel 0, the pin If meanwhile restingagainst the vertical portion t of the finger i On the key being released the lever is brought back to its original position (and with it the connecting-rod S by means of the spring The rack T is now returned by the spring i the pawl 25 riding over the teeth of the said rack. lVhen required the pawl 6 maybe put out of gear and so held by the spring t". The spring 13 also serves to hold the block L against the wheel M. If desired, the pawl 2? may engage the rack in the reverse direction.

For the purpose of spacing the words I provide an additional key V, having a foot "0, which, when the key is depressed, causes the sloping finger t to engage the pin 6' 011 the end of the toothed rack T, and thus moves the paper-carrying roller forward the necessary distance. lVhen pressure is removed from this key, it flies up under the action of spring 12. The rack T being thus released, it moves back, as before, under the action of spring i the pawl 25 riding over the teeth of the rack. The spacing-k ey V is depressed by the pivoted lever V, having a pedal or finger bar V which is supported at its other end 011 a similar pivoted lever V By means of the fin ger'bar V the spring-key V may be work ed conveniently by either hand.

The sheet of paper Q is held in position on the roller by means of a clip or holder r Figs. and 11. The clip r is attached to a rod r which passes the whole length of the roller-frame R and is hinged thereto at 1' Figs. 1 and 3, being held in position by the spring 7'. The roller-frame R being withdrawn clear of the type-wheel, the rod r carrying the paper-clip, is thrown back by means of the handle 0, Fig. 4:. The edge of the sheet of paper is slipped under the roller, being guided thereto by the guide r then passed over it and the clip brought down again. The clip 1- has an opening r Fig. 4, a portion of the surface of the paper being thus left exposed, so as to receive an impression from the type-wheel. The paper is moved in the direction of the arrow, Fig. 3.

Each key-lever J is provided with a stop ping device or plate j, secured thereto, having projections ff, Fig. 9, at its end for engaging pins or projections is on the disks K K K attached to spindle D.

The handle U, Figs. 1, 2, and 6, is pivoted at a, and is connected with the key-frame H by means of a connecting-rod u. The keyframe can be moved longitudinally on the guide-rods E by means of the handle U, so that the projections j j on the stop j will engage the pins on the disks K when the handle is in the position shown in Fig. 6. When it is moved toward the left or right, the stop-platej will engage,respectively, the pins of disks K and K. The frame is locked in the desired position by means of the pin a which engages depressions or holes 7.6 ii the sprii'lg-plate a The keys bearing their respective letters, figures, symbols, &c., may be arranged as shown in Fig. 5; but of course many other an rangements may be adapted. To print large characters, &c., the key-frame H is moved longitudinally, so that all the stop-plates j will engage the disks whose projections k correspond with the large characters on the type-wheel. Disks K may be conveniently used for the large characters. The first key in the front row is, for example, depressed (which on Fig. 5 is marked with the letter L) until its shoulder g rests on the frame H. Its movement depresses the key-lever J, also the front end of the lever O, by means of bar P, thereby raising the arm 0 and withdrawing the block L from the brake-wheel M, so that the type-wheel will rotate under the action of the spring in barrel F. One of the proj ections j or j of the stopplate j will, however, engage a pin (marked L, Figs. 9 and 10) on the disk K corresponding to letter L on the type, and will therefore instantly stop the motion of the type-wheel C, the letter L on the said wheel being thenin aposition ready for making an impression on the surface of the paper exposed by the opening in clip T The lever O, besides releasing the brake-wheel, actuates, by means of the rod S the lever t causing the paper-roller to be moved longitudinally the space required to print one character, and afterward raising the said roller against the type-wheel, as before described. As soon as the key is released it flies upward under the action of spring J, the brake is again applied to prevent the type-wheel rotating, and the paper-roller is lowered. If the second key in the same transverse row is now depressed, which on the drawing is marked P, the brake is released as before; but the stop-plate 7" descends a less distance than with the first key, and therefore does not engage pin L, Figs. 9 and 10, on the disk K, but a pin P, Figs. 9 and 10, correspoiiding to P on the type-wheel. The remaining keys in the row stop the type-wheel in an exactly similar manner. As each key descends a greater or less distance, the stopplate 3' can engage only one pin on the disk, and it is evident that the remaining pins cannot be engaged by it, because the projection 7' orj on its end is not of sufficient width to engage more than one pin at a time. The remaining rows of keys are arranged in a similar way; but it will be evident that the pins on one disk K are not placed in the same position relatively to those on the other disks, but either lead or follow the pins thereon. If there are, for example, as shown in the drawings, seventy-five characters on the type-wheel, and all the said characters are the same pitch or distance apart. then the pins on each of the disks K, K and K will lead or follow the pins on one .of the other disks (preferably the one nearest to it) by an angle subtended by one seventy-fifth part of its circumference, Figs. 9 and 10. L P &, Figs. 9 and 10, represent, for example, the pins on the first disk K. Z A' represent the pins on the second disk K; X S E,'the

pins on the third disk K, and so on. 1 prefer to place the pins on each side of. the disks and on the lines of two circles of different radii, Figs. 9 and 10; but, if desired, the pins may be provided on one side only, or they may be arranged on the lines of more than two circles. When the pins in are arranged only on one side of the disk, one projection 3' or 7' only is required.

its guide-rods so that the stop-plates j will engage the disks whose pinscorrespond with the figures on the type-wheel, preferably the disks K There are generally only a limited number of figures and symbols required for general use, and therefore a limited number of pins will be required on these disks. The

third and fourth keys in the first row are marked, for example, with e and 8:, and therefore its disk will be provided with two pins corresponding with the fraction 1} and the character & on the type-wheel. These pins are represented on Fig-1O by 7% and &. The second disk, in accordance with the arrangement of keys illustrated on Fig. 5, will be provided with one pin, (represented by 3 on Fig. 10,) the fifth disk with two pins, (represented on Fig. 10 by 6,) and so on. and L) and the three first keys in the second row (W A Z) will not engage any projection on disks K if they are depressed. The small plates 9' on the rear key of each row are only provided for convenience, as there is gener-' ally not sufficientspace for the representation of more than one character on a key.

be shifted so that the stop-plates j engage the disks having pins in the same relative position as the small characters on the typewheel, preferably the disks K The first disk K will therefore have pins represented on Figb3 1,77 6 p, 6 Q1377 C (87-77 W is a warning-bell, preferably attached to the hinged bed S. The pivoted projecting pin or snug w actuates the hammer to each time the frame approaches the end of its travel and thus indicates when the end of a line is nearly reached. The pawl t can then be raised and the paper-roller drawn back to commence a fresh line of printing. The snug w,-bein g pivoted, only actuates thehammer in one direction.

If it is desired to repeat the impression of a character two or more times in succession, it will be evident that each time the key is depressed it will, in the ordinary manner,

cause the type-wheel to make one completerevolution for each impression. If letters are thus frequently repeated, the spring in box F would rather quickly spend its force. To obviate this I provide a block X, which is brought into engagement with the brakewheel M independently of the block L, be fore described. The block X is faced wit-h some yielding material, so that when de-' pressed it will grip the wheel M and prevent The first two keys in the first row (Pv ed on a spindle m, which passes through the lever V and is supported thereby. The upper end of w is fitted with a push-head m, and between the said head and the lever V a spring as? is inserted, so that the block X is held clear of the wheel M even when the lever V is depressed; but it is free to move when required independently of said lever To print figures the frame H is shifted on by pressing on head 00' to hold the wheel M while repeating letters and economize the force of the driving-spring. The same character may thus be printed in succession as many times as required. 7

The ink is preferably carried on one or more small rollers Y, carried on spindles y, secured to a hinged or pivoted lever 31, which is preferably carried on the standard B. When the machine is in use the type-wheel is constantly rotating, and the ink-roller Y is therefore brought into contact successively with each of the letters, &c. The weight of the roller keeps it on the face of the typewheel; but if two or more inking-rollers are provided at the sides they may be held against the surface of the type by means of a spring.
