TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 419,396, dated January 14, 1890.

Application led November 12, 1886. Serial No. 218,731. (No model.)

To all whom t may concern.'

Be it known that 1, THOMAS D. WORRALL, a citizen f the United States, residing at Lynn, in the county of Essex, State of Massachusetts, have invented certain new and usefullmprovem ents in Type-Writin g Machines, of which the following is a specification, reference being had therein to the accompan yin g drawings.

My invention relates to certain improvements in type-writers; and it has for its ob- Jects to provide a type-writer'of simple construction, easy to operate either by hand or vfoot power, and also suitable for making heavy impressions, such as used in engraving, &c. These objects I attain by the means illustrated in the accompanyingv drawings.

Figure 1 represents a front elevation; Fig. 2, a transverse sectional view; Fig. 3, a front elevation showing the type-carriage elevated and broken away; Fig. 4,a detail view of one of the brackets in which the rod on which is suspended the type-carriage is guided and held in position; Fig. 5, a side elevation of the paper-holding carriage Fig. 6, the opposite side thereof; Fig. 7, a top view of the same; Fig. 8, a detail of the impression-bed; Fig. 9,a

detail of theink-pad-holding device; Fig. 10, a

detail of one of the slides for same; Fig. 1],a detail of the pawl-pivot-holding device; Fig. 12, a detail of the device for holding the typeholder in position; Fig. 13, av front view of said device; Fig. 14, a view of one of the paWl-pivots. Fig. 15 is afront view of a portion of the resister or spacing plate or roller.

The letter A indicates the base of the machine, provided with suitable legs B, and has fixed upon it at opposite sides the standards e, in the top of which is mounted a rock-shaft D. On this rock-shaft is secured at each side the arms E, which connect to a shaft or rod F by means of the links G. This shaft is guided and held in position by the brackets ,H at each side of ythe machine, and being secured to the standards C, and on the same vrod orl shaft is pivoted the type-carriage T, which is free to move either up or downv and to slide back and forth from one side of the machine to the other. The bracketsv H are provided with slots for the reception of the rod F, and in the bottom of said slots are placed the setscrews b2, on which the rod F rests, and by which the rod an d the type-carryin g frame are adjusted in a vertical direction.

The type-carriage consists of a frame T, pivoted at one side to the rod or shaft F, and in the other is journaled the type-holder K, having at one end a disk or wheel L, provided with apertures M, in which fits a pin N, for the purpose hereinafter described. 6o

Just above the type-holder on the typecarriage is situated a toothed or slotted register-plate P, the teeth of which are graduated to suit any required type, and may be so constructed that it can be turned so as to bring into operation the slots or teeth needed to correspond with the type to be used. This plate can be directly slotted or toothed; but, as shown in the drawings, I employ two plates B and S, between which are secured quads 7o and spaces divided by pieces of steel or brass or other suitable material made longer than the quads or spaces, so as to form the necessary interstices; or this registering device may be made as a cylinder and provided with 7 5 any number of the slotted or toothed edges and accomplish the same purpose, the cylinder to revolve and work in the same manner as the type-holder, as shown in Figs. 12, 13, and 15. The plate is lettered directly 8o over each slot therein to correspond with the letter or character in the type-holder below, so that when depressed upon the centeringwheel T, to be hereinafter described, the letter directly under the slot isk brought to an exact printing-center.

U indicates a plate secured to cross-piece V of the main frame, and directly in the center between the two standards the aforesaid plate has an extension V secured to it, on 9o which is a depending arm carrying the centering pin or wheel T. Either can be used, and when pins are used different sizes are inserted to correspond tothe slots in the registering plate or device; but when a wheel is used it is constructed of cogs of different sizes around its periphery and can be turned to suit the differen t-sized slots in said registering-plate.

On the extension W of the plate U and at ico the top thereof is pivoted an arm Y, provided with a set-screw Y', which, in connection with' the depending arm carrying the centering pin or wheel, serves to guide the registerplate and type-carriage as it travels to and fro and keeps said plate and type-holder at all times in exact distance over the centering pin or wheel, causing always a perfect interlineation-z'.. c., the register-plate and the type-holder being made true, and the type once properly aligned, the guides V XV, above spoken of, willnecessarily bring each letter into line, and the printing will be perfectly straight. The arm X can be turned upon its pivot out of the way when it is necessary to elevate the type-carriage, and the set-screw therein is for the purpose of holding the register-plate and type-carriage securely in position, but leaving sufficient space for the formerto slide back and forth, thuspreventing any forward motion, which might otherwise cause imperfect lines in printing.

The rod F, at its ends and outside ot' the brackets, is provided with nuts Z, in which are secured rods A', extending down through the base and connecting by means of similar nuts to a cross-rod I3', which extends the entire lengt-h of the machine. Iivoted t the rear of the base and extending forward is a rod C', which rests upon the rod B', before described, and when it is depressed it operates the type-carriage, causing the type to print. This can be operated bythe hand, or

a treadle can be attached to the end of the rod c' to facilitate the operation by the foot. This is where greater power is needed than ordinary writing, as in manifolding, stencilcutting, engraving, or other heavy work.

In the center and at the rear of the rockshaft D is an arm D', and at the back of the machine, on the cross-piece thereof, is a loop E'. To these I att-ach a spring or springs D, which have act-ion upon the type-carriage, holding it in itsnormal position. This action is done by the recoil of the springs after depressing the type-carriage to print a letter.

Seated in suitable ways in that part of the frame lettered U, and adapted to slide ver tically therein, is a frame F', carrying at its lower edge a pan'Gr', constructed of a thin piece of steel or brass or other suitable material, said pan projecting completely under the type-holder. Directly in the center of the pan is a slot H', located above the impression pin or bed.

The opening in the metal pan which holds the inking-pads is provided with spring lips or projections d", adapted to receive and hold the removable plate d5, and also to hold the paper down on each side of the impression point or pin, said plate being provided with a slot ct, through which the type pass to impinge on the paper to be printed. This provides for the printing of the one letter directly over the slot, the balancebeing covered and prevented from printing by the pan. Several of Jthese removable plates (t5 are kept on` hand, each having slots of diiierent widths to eorrespoml to the size of the type being used, so that only enough paper is exposed to receive the impression of the type at the impression-point.

In the pan and at each side of the slot I provide inking-pads I', made of any suitable material, so that every time I print a letter or character the balance of the type are taking ink, by which means I secure abundant distribution of ink on the face of the type.

It must be obvious that in order to get a free movement of the type backward and forward over the inking-pads there must be a diiference in the movements of the pan or pad-holder and type-carriage, it being' neeessary that the type-holder should leave the pads in order to secure the free movement back and forth while changing the position of the letters so as to bring them consecutively to the printing-center. I meet this object as follows: J J' are two arms on the rock-shaft D, connecting to the pad-holding frame by the rods K' K', which project a less distance forward than the arms which operate the type-carriage. These arms being shorter, it follows that they would not, when in motion, travel so far; hence the type-carriage would rise faster and higher than the pad-holder, thus securing a free movement without dragging on the pads. The rods K' are pivotally connected to the pad-holding frame and pass up through apertures in the arms J'. They are screw-threaded and held in position by nuts. This is for the purpose of regulating the throw of the pad-holder to correspond with the throw of the type-carriage, so that when the single type is printing the balance is at the same time inking. To further help the raising of the pad-holder, I provide springs L3, attached thereto and to the main frame. A crossbar L' is adjustably secured to the pad-holding frame, and may be placed in different positions. This bar operates on a pin M', securedv to a pivoted arm i on which is pivoted the pawlv O' for operating the paper-carriage P'. The pawl O' operates upon a rock-bar connected to the paper-carriage, as also does a retaining-pawl R', pivoted to the cross-piece of the main frame, and is held in position by means of a spring i". The pivots of the retaining-pawl and of the pivoted arm N' extend through to the back of the frame, and are held in position by means of hooks T', which fit into grooves in said pivots. The arm N also contains, besides the pawl, a series of perforations for the adjustment of the said pawl, and the pad-holding frame also contains perforations for the adjustment of the cross-bar L', both to regulate the throw of the typecarriage.

The paper-carriage P' consists of a rectangular t'rame U', mounted on wheels V', which roll upon the base of themachine, said frame having between the front and rear thereof brackets YV', to which is attached the rack-bar X', or a double or triple rack-bar may be used to move the carriage to space IOO IOS

TIO

the letters laterally. The lower extremities of the above-named brackets are grooved,

adapted to fit over and slide upon a T-rail riage is the paper-holding frame Y', which slides at right angles to the line of the type. This frame has attached to one side a rackbar Z which is operated by a pawl A2, pivoted to a lever B2, which is pivoted to the papercarriage. An adjustable stop C2 is situated in r'ear of thelever, and is attached to the paper-carriage also, and held in position by a screw or bolt passing through -an elongated slot therein for the adjustment.

The above-described arrangementis for the purpose of spacing the distance between lines, and the width ofsaid space is regulated by the adjustable stop by either moving it backward or forward. The lever coming in contact with it stops the throw of the paperframe# At the rear of the paper-frame are the paper-holders D2, consisting of a small plate attached to .a threaded bolt, which passes through the frame, and on the under side of the frame is provided with springs and a nut for tightening or loosening, as desired. At the front and on the top of the paper-frame is a movable slotted plate or bar E, in the slot of which are ad justably secured fasteners similar to those described at the rear of the frame. The slotted bar itself extends the width of the frame, and at' one side has a downward projection provided with a pin,

' which slides in a slot of a plate F, secured to the side of the frame. rlhis bar and attachments and those at the rear are for `holding the-paper to be printed upon. The adjustable slotted bar is regulated back, and forth to suit the size of paper used.

Beforeputting the paper in place I cover the entire paper-frame with a covering of suitable material-such as linen or cotton and itis held in place by arod G, journaled between the sides of the frame, and by the fasteners D2 at the rear.

It isv evident that I provide arrangements suitable for any size paper, may it be long or short, wide or narrow.

Attached to the under sidev of the papercarriage is a recoil-spring I which at each release of the driving-pawl brings and holds the vcarriage against the retaining-pawl while or beds thereon, varied in size according to the size of type used, the top of the pin being slightly'larger than the type to be used in connection therewith, and the said top isconstructed of any suitable material, such as rubber. The wheel is held securely in posi- 'tion and preventedfrom turning by a setscrew passing through the side of the brackets and pressing against the Wheel itself, and

' and the impression pin or bed is in place the top of the pin only touches the paperand the ypaper slides freely back and forththereon. The rising in the paper thus made by the pin I prevents a blurring of letters, as it would 1 should the pin only be under the paper with-4 out pressing. In regard lto spacing in my invention, by changing the position of the pawl or pawl-bar,

V elevatingor depressing the cross-bar, or shortening or lengthening the rods that connect the pad-holding frame with the slotted arms, I can cause the driving-pawl to move a greater lor less distance, and thus take two or more ,f the same or different fonts of type. As before stated, to accommodate different l sizes of type I make the slots or perforations large enough for the largest and then provide slides of different sizes made out of thin steel r or other material, which t over the slots in f the plate, and in which I cut slots to correg spond with the Width of any-sized typeI may l use, changing these at pleasure withv the lchange of type. The plates are lettered to correspond with the type in the type-holder, each letter or character being over the slot f directly over the corresponding letter o r char-Z acter in the type-holder, as also before stated, so that when depressed upon the cogs or j teeth of the centering-wheel the letter dii an exact printing-center. 4

i For regular spacing I change the pawl from -fine to coarse toothed ratchetbars, or thel reverse, in the following way: The pivots of the pawls are provided with grooves L and said pivots work loosely in their bearings, so that they can be easily pushed through one way or the other at pleasure, carrying with them the pawls which are secured thereto, the grooves being the same distance apart as the rack-bars are wide, and after changing they are held in that position by the hooks before described.

With the description of the mechanism of my type-writing machine its operation will be readily understood to be as follows: The type-carriage moving to and fro on the rod F and carrying the type-holder and t-he registerrack being in position, the operator brings the interstice bearing a given letter directly over the tooth or cog of the centering-wheel.

by hand or foot, the corresponding letter in the type-holder is presseddownward through when the paper is secured on the carriage' rectly under the opening or slot is brought to` Then by depressing the type-carriage`, eitherv teeth at pleasure, thus giving irregular spacing to suit the different widths of letters inv IOO IIO

the slot in the pad-holder, or that of one of l the slides on the paper held firmly up by the impression or bed-pin or wheel, and the impression is made and the letter printed. In this act of depression all letters but the one in use are brought down upon the inkingpads arranged at either side of the slot, and are thus inked simultaneously with the printing. It will be seen that I do not strike with an impression-key upward through the blanket or paper against the type, but the impression is made by the downward movement of the type onto a fixed bed-pin or wheel over which the paper moves. By the recoil or return movement the pawl is moved so as to push forward the paper-carriage step by step to feed the paper, said pawl being lifted by the cross-bar and springs. At the end ot' a line the pawls are lifted by hand, and by the recoil of the spring the paper -carriage is brought back for a new line.

The cross-bar to lift the pawls may be attached to the type-carriage or the pad-holding frame with equal facility.

Having thus described my invention, what I claim, and desire to secure by LettersPatent` 1s*- l. The type-carriage carrying one or more fonts of type, operating in a lateral and direct vertical movement over the impressionpoint, as set forth.

2. In a type-writing machine, a type-registering device having a series of teeth of varying widths to correspond to type of varying size carried by the type-holder, said registering device being adapted to be turned or adjusted to bring into use any-sized rack to correspond with the type in use in the typeholder.

3. In a type-writing-machine, a centeringwheel having cogs or teeth of different size, in combination with an adjustable registering plat-e or roller having slots or teeth of different size to correspond with the teeth of the centering-wheel, as set forth.
