Application filed March 23, 1885. Serial No. 159,815. (X0 model.)
To all whom it may concern:
Be it known that I, THOMAS D. WoRRALL, a citizen of the United States, residing in Washington, in the District of Columbia, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to improvements in to type-writing machines.
The object of my invention is to provide a simple and inexpensive machine which can be readily operated by any person whether skilled in this art or not.
Referring to the drawings, Figure 1 is atop or plan view of my improved type-writer, showing a series of independent fonts or batteries of type. Fig. 2 is also a plan view showing a series of fonts of typein one holder,
adapted to be rotated or turned on pivots or tional view on the line :10 x of Fig. 1.
3o placed in reverse position.
trunnions. Fig. 3 is a view in perspective. Fig. 4. is a detached view of the series of rack-bars and the swinging lever, with the adjustable pawl. Fig. 5 is a longitudinal sec- Fig. 6 is a sectional view on the line 3 3 of Fig. 2. Fig. 7 is a similar view on the line 00 x of Fig. 1. Fig. 8 is an end view ofa type-hold ing frame in which one series or set of type is Fig. 9 is a sectional view of another form of type-holder. Fig. 10 is a view of the detached side of the type-holder shown in Fig. 9.
A indicates the base or bed of the machine,
to which are secured the plates B B and standards or supports B B.
c c are guide-rods supported in the standards, which pass through the side pieces of thepaper-ca-rrying frame, and by which means 0 said frameisguided in its reciprocating movements.
D is a guide-bar, which is also secured in or supported by the rear standards, B, and on which the rear end of the type-carrying frame E is mounted in such a manner that said frame is free to move back and forth on the guide rod.
The type-carrying frame may be secured to the guide-rod D in any convenient or desirable manner; but I prefer to pass the guide-rod D through holes in the projecting ends of the type-frame, as shown, so that the front end of said frame can be readily raised and lowered.
F is a plate, of metal or other suitable material, secured in the upper ends of the front standards, and is provided with lugs a, in which the front end of the impression-bar or hammer G is pivoted, as will more fully hereinafter appear.
H is a carriage or frame for supporting the frame I, which forms the paper bed or support, said carriage being provided with wheels or rollers J, and guided in its reciprocating movements by the bars O O, as before indicated. The rear portion of the carriage His provided with one or more upwardly-projecting plates, K, the upper edges of which have serrations I), which form a rack or ratchet-bar, in which the operating-pawl L and retainingpawl M operate to move the carriage the proper distance to space the letters, and retain the same in position until the impression has been made by the type.
It will be noticed that the series of toothed rack or ratchet bars K are provided with teeth or notches of different size, so as to enable the paper carriage or bed to be moved the proper distance required for different-sized type. For example, we will suppose that large type are being used. The pawl L, as shown in Fig. 4., will rest in and operate the carriage through thelarge ratchet-teeth 1. If medium-size type are used, then the pawl is placed in the teeth 2, and if small type is used, then the pawl L is placed in the teeth 8. It will be noticed, however, that the pawl Lis adj ustably secured to the bar N by means of the set-screw c or other suitable device, said bar being pivoted to the frame or bracket O, so that by adjusting the pawl L toward and from the pivotal point of the lever I am enabled to regulate the throw of the pawl, and thus control the move ment of the paper-carriage without resorting to the use of the different ratchet-bars l 2 3. It will be understood that the frame or bracket 0 is rigidly secured to the base A and that the retaining-pawl M is pivoted thereto, so that when the carriage H is moved one or more notches it will be held in its forward position by said pawl. The leverNand pawl L are operated upon by a spiral spring, I, one end of which is secured to the bracket or frame 0, while the other end of said spring is secured to the lever N, by which means the free end of the lever is raised and the pawl L drawn back to engage with another notch or tooth in the rack-bar.
Q is a stud or pin secured to the pawl-lever N, and projects forward under the bar S, secured to'the rear portion of the type-carrying frame E, so that when the front end of the type-carriageis raised the bar S will impinge on the stud Q and depress the pawtoperating lever N, and thus move thepaper-carriage the proper distance to space the letters. This is a very important feature of my invention, for it will be noticed that the front end of the type frame or carriage can be raised and lowered any desired number of times without depressing theimpression-key, and by this means the paper-carriage can be moved forward any desired distance without bringing the type into printing contact with the paper; or, in other words, the free motion, being independent of the motion of the type frame or carriage which operates the impression-lever, several or any number of teeth of the ratchet-bar can be operated upon before the impression of the type is made on the paper, and by this means the operator is enabled to space out-the words at the end of the lines without making a mistake in the division of a word.
T is a spiral spring one end of which is secured to the paper-carriage and the other end is secured to the base A, so that when the carriage has been moved over its full distance to form a line of printing, on releasing the pawls L and M from the rack or ratchet bar the carriage will be drawn back to.the proper position to print a new line by the recoil of the spring.
Having described the parts which operate the paper carriage to produce the proper spacing of the letters, I will now proceed to describe the type holders and the devices which operate to produce the printing. The type-carrying frame is adapted to receive and hold one or more fonts or batteries ofdifferentsized type, and is so arranged that the fonts or batteries can be readily interchanged to bring the large or small type into use, as occasion may require.
In Fig. l I haveshownaseries of type-holders, V, or fonts of type arranged in the typecarriage, and which may contain type of different size. These type-holders may be held in the type frame or carriage by means of screws, springs, or other suitable retaining devices, which will enable the operator to quickly move the desired font or battery of type into the proper position to be operated upon by the impression-lever. I have shown two forms of type-holding bars, but do not wish to confine myself to such, as it is obvious that other forms can be used without departing from the spirit of my invention, the main feature of this portion of my invention being the grouping of the type into a compact form, so they can be readily brought under the impression-\ key.
The form oftype-holder shown in Figs. 9
and 10 consists of a slotted piece of metal, or
of two pieces of metal, W, secured together and having a central aperture or cavity .for the reception of the type-holding pins, a ledge or flange, 01, being provided, which forms the point of contact or resistance for the spiral springs which surround the type-holding pins. The type-holding pins consist of the head 6, which may be flattened at the sides, so as to bring the pins closer together and also prevent them from turning, and a smaller or contracted portion, f, which projects through the slot in the type-holding bar, and to which the type are secured in any convenient man ner, or the shank of the type may be secured in the heads or pins 6 and form the portion which projects through the slot of the typeholding-bar. g are spiral springs which surround the contracted portion of the type-pins, the lower ends of which rest on the ledge d, while the upper ends impinge against the under side of the head 6, the office or function of the springs being to raise the type and type-pins from contact with the paper as soon as the impression key or hammer is raised, while the stops or pins h on the contracted portion f prevent the pins from being forced too high by the action of the springs. By this construction of type-holder I am enabled to bring the necessary font of letters, figures, or characters into a comparatively small compass.
In Figs. 2 and 8 I have shown another form of type-holder, A, which is designed to hold type of different kinds and sizes. This typeholder consists of an upper and lower perforated plate secured together by end plates, and between which the type-pins are held, as shown in Fig. 8, the ends of said type-pins projecting through the perforations in the plates. The type-holder A is mounted on trunnions O in the type-carrying frameE, and the type pins on each 'side are set in reverse direction, so that when a large or small type or upper and lower case is required all that is necessary to be done is to turn the type-holder on its trunnions and bring the line of type in proper position undcrtheimpression-key. By having a series of pins on the impression-bar and by turning the font or battery A on its trunnions lam enabled to print properly with out any lateral movement of the font to bring the type into printing position. This I accomplish by adjusting the proper pin, Z, in the impression-key and moving the paper-table I back or forward, as the case may require, so as to bring the paper into the proper position to receive the impression from the type, and thus form a printing point or center at any point along the impression key or hammer. The type-pins in this form of holder are provided with spiral springs,shoulders, and stops, so they will have the required vertical movement in the holders, when operated upon by the impression key or bar, to effect the printing and be returned again to an elevated position by the spiral spring when released from the pressure of the impression-bar. As
before stated, G is the impression bar or key,
pivoted at its front end in the lugs to of the bar F, and adapted to work in a slot or recess, i, in the plate F. The outer end of the impression key or bar is held up from contact with the type pins by means of the spiral or other spring k, said spring being of suffieient strength to hold not only the impression-key, but also serve as a support for the front part of the type-carrying frame when the machine is not in use. The impression key or bar is provided with one or a series of screw-threaded apertures, in which the screw-threaded pins Z are inserted, by which means any one or all of said pins can be adjusted to operate on the type-pins. The heads of the type-pins are provided with a suitable-shaped cavity to receive the lower ends of the pins Z, by which means the type are properly centered or brought to the desired position before theimpression-key G is depressed to effect the printing. The type-pins may, however, project some little distance above the holder and be adapted to fit into rec. sses formed in the under side of the impression-key, thus effecting the same result. As a guide to the operator, and also as asafeguardtoinsuretheproper centeringofthe typepins under the impression key or bar, Isecure to the type-carrying frame E an index-plate, D, provided with numerous apcrtures,whieh are lettered or numbered to conform with the type in the type-holder. This index-plate may be adj ustably secured to the type-carrying frame, as by set-screw E and may be provided with a series of rows of apertures, each set of holes being adapted and arranged with relation to the font of type with which it is usedviz., should a'fout of,say,nonpareil be used the holes would necessarily have to be closer together than when pica or other larger type is used. m is acentering point or pin secured to the upper side of the impression-key G, so that when one of the perforations in the index-plate bearing the proper letter is brought over the pin m and the front end of the typecarrying frame depressed the proper letter or character will be printed on the paper. By this means two centering-points for the impression-key are providedviz., the pin m and the pin Zwhich enter the cavity in the top of the type pin, thus providing a safe and reliable means for bringing the proper type into printing position. The type in the typeholes and the lettered holes in the indexplate are systematically arranged with relation to the letters most used by printersfor example, the letters E T S, &c., are arranged together or in close relation to each other, so that the type-carrying frame will not have to move any great distance, or its entire length, except at intervals, to bring to the printing center some letter or character not frequently used.
In Fig.1 I have shown a series of typeholders mounted in the type-carrying frame,
and also a series of pins in the impression-key G, which register with the type-pins in the holder, the letters or characters being arranged the same in all the type-holders, by which arrangement I am enabled to print in duplicate or produce any desired number of lines at one and the same operation. This arrangement of type and method of operation will be found specially useful in ribb0n-printing and in reporting a number of copies of stock -reports, market quotations, &c. The type-carrying frame is provided with knobs or handles E at the front corners, by which the front part of said frame is moved up and down and also moved back and forth, to bring the proper letter under the impression-key. The paper-holding frame I is adapted to slide in ways in the carriage H and at right angles to its line of motion, and is provided with a series of ratchet-teeth, a, on the upper edge of its sides, adapted to receive the pawls p,which are secured to the ends of the bent or bellcrank levers 0', said levers being pivoted to the sides of the carriage H. By this construction I am enabled to move the paperholding bed forward the desired distance to print or write another line by simply raising the outer ends of the bell-crank levers 1'.
F is the bottom of the paper-carriage, and consists of a board or metal plate adjustably see'ured to the frame or carrier I by means of set-screws G. This construction enables me to raise or lower the paper-support so that the operator can write in books of different size or on tablets or pads as well as on a single sheet or thickness of paper.
H H are inking-tables secured at each end of the frame-work ofthe machine, and are supplied with the ordinary orany suitable ink in any well-known manner.
I I are inking-rollers mounted loosely in brackets K on the ends of the paper-carriage, and receive their supply of ink from the tables H as the paper-carriage is brought back and forth in the printing operation.
L L are ink distributing rolls loosely mounted in suitable hearings in each end of the type-carryingframe. The function of the distributing rolls L is to distribute the ink evenly on the ink-rollers I, so that as the type-carrying frame is moved back and forth in the process of writing the ink will be evenly distributed on the rolls 1, and the type will be kept at all times supplied with ink by reason of their contact with the inkrollers.
WVhen it is desirable to use an inking-ribbon instead of a regular inking apparatus, as described, I remove the ink-distributing rollers L, and in their place substitute reels or rolls, by means of which the inking-ribbons are brought under the font or battery of type.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. The combination, with the type-carriage pivoted so as to be capable of a rocking or swinging mot-ion, and having spring-seated type, of an impression-key fixed at the printing-point, the whole being constructed and arranged substantially as described, so that the impression-key is depressed and the impression made on the downward movement of the type-carriage.
