SPECIFTCATION foliiliilg part of LettersPatent No. 339,078, dated March 30,1886.

Application filed August 19, 1885. Serial No. 174,819. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES SrIRo, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in TypeWVriters, of which the following is a specification, reference being had to the accompanying drawings.

- This invention has relation to that class of type-writers in which are employed a type wheel or disk and devices for rotating the same to bring a desired printingcharacter to the printing-point.

Among the objects of the invention are to simplify the construction, reduce the number of parts, provide upper and lower case characters, enlarge the dial, whereby the indicating-characters may be larger and more readily selected, facilitate rapid change from upper to lower case type, arrange the entire feeding mechanism below the table and centrally beneath the platen, arrange the impression and feeding devices so as to receive force in substantially a direct line, and to secure other advantages in construction and operation hereinafter more fully described.

The novel features of the invention will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan, Fig. 2 is a front elevation, and Fig. 3 a bottom plan, of a ty1. e-writing machine constructed in accordance with my invention. Fig. 4 is a section of the carriage and platen on the line X of Fig. 2. Fig. 5 is a side elevation of the carriage, bracket, and guiderod. Fig. 6 is a sectional detail illustrating the manner of attaching the rack-bar to the carriage. Fig. 7 is a partial bottom plan of the printing plate, wheel, or disk. Fig. 8 'is a side elevation, with parts in section, of the feeding devices. Fig. 9 is a side elevation, with adjacent parts in section, of the inking devices. Fig. 10 is a detail of the free end of the inker-arm.

Like letters indicate like parts in all the figures of the drawings.

Arepresents the base of the machine, which in this instance is formed of a single piece, and is provided with feet A, which support the base above a desk or table, and provide a space between the desk and the base for the feeding devices hereinafter described, all of which are located beneath the base.

B represents a bracket, which may he formed as a part of the base, but in this instance is secured thereto by screws B. This bracket serves the purpose of supporting the printingdisk, the dial, and the impressioirlever, for which purpose it projects over the base, as shown by dotted lines. Fig. l. lhe bracket is provided with a central boss or hub, B, to which is secured the dial G, the screws C, Fig. 1, passing through the dial and into the end of the boss. The dial and boss are pen forated for the reception of the spindle D, at the lower end of which is secured the lockingwheel E and the printing wheel or disk F,

it is inclined in order to present but a single printingcharacter upon the printing-field, which is substantially atthe point indicated by the arrow Y. It is readily seen that without this inclined arrangement of the printingdisk more than one character would be impressed at the printing-field, as it is located upon the platen or roller, which is disposed horizontally upon the carriage. The locking wheel may or may not be also inclined as shown.

At the upper end of the spindle D is pivotally secured the impression-lever G, which extends completely across the dial 0, and is provided near each end with hooks G G", which extend inwardly beneath the dial, and come in contact with its under surface.

Below the lever G, and encircling the spindle, isa coiled spring, 1),which bears against the under surface of theimpression-lever, and upon a double-pointed indicator, D", which is perforated to embrace the spindle, and is provided with a lug (not shown) to project into a longitudinal slot, D, formed in the spindle, whereby the spindle may be vertically reciprocated, and yet serve to horizontally rotate the indicator. One of the points L of the saidindicator is employed to indicate characters of the uppercase, the latter indicatingcharacters being shown in Fig. 1, while the which is mounted upon the spindle D so that indicator is employed to indicate characters of the lower-case,while the opposite point, U, of

former are intended to be represented in the unoccupied portion of the dial, as represented by dotted circle in said figure. An additional circle of characters as those indicating numera1smay be arranged within the outer circle, as shownin Fig. 1, so that with one or the other points of said indicator pointing thereto said character shall be brought to the printing-point, the usual relation between the indicating-dial and the printing wheel or disk being observed by properly locating the printing-characters upon the printing wheel or disk.

As thus far described, it will be seen that by turning the impression-lever horizontally around the spindle as a center the indicator D, the spindle. the locking-wheel, and the type-disk will all be simultaneously rotated, andby depressing one or the other ends of the lever the locking-wheel and the type wheel or diskwith the spindle will be depressed and the character indicated will be printed.

XVhen it is desired to operate thelower-case, the handle H of theimpressionleveris brought into use, so that that end of the indicator which selects the lower case type will be brought under observation in selecting the character to be printed. After the character is selected the handleHis depressed, as shown by dotted lines, Fig. 2, when the hook Gr at the opposite end of the lever acts as a fulcrum, and the hook G is depressed with the lever, as shown by dotted lines.

I here emphasize the fact that I secure mo tion of the spindle in a direct line at the expenditure of a minimum force, because of the pivotal connection of the impression-lever centrally with the spindle, while the necesa glance whichrclass oticharacters is sary lateral movement is provided for at the end of the hook G, which is rounded to reduce friction, while it moves outwardly from the center, and upon the under surface of the dial. In this construction the friction occurs at one point onlynamely, the extreme end of the hook, which is rigidly connected with the lever instead of being pivotally connected therewith and pivotally embracing a ring arranged concentric with and below the lever, as heretofore. s

By employing the opposite handle, H,of the il'npression-lever the opposite end of the indicator is brought into use, whereby characters of the uppercase are selected, so that all that is necessary to change from upper to lower case is to change the handle employed.

In making the impression the ditferent outlines of the ends of the indicator, the different positions of the handles, or theletters L and U upon these parts are adapted to show at bein employed. Furthermore, the particular ar rangement of the parts of the machine is such that the work is directly in sight of the operator at and immediately after the impression of each character. This advantage is as full and complete as in the use of an ordinary pen or pencil, in that the last character printed is instantly brought to sight, and the work can readily be returned for correction, so that another character can be imprinted directly upon a preceding one, the entire operation being governed by the sight of the operator and without any calculation as to the mechanical spacing required to reach the exact printingpoint. I

Upon the top of the bracket B is a screw, B, passing through a slot, B, and into alocking-bracket, B (see dotted lines, Fig. 2,)which projects downwardly, and is provided at its lower end with a V-shaped flange, B", Fig. 1, which is adapted to mesh with the teeth on the periphery of the locking-wheel E. A de tentspring, E, is also secured to the inner face of the bracket B, and its free end rides in the teeth of the locking-wheel. The point of the spring which meshes with the teeth is at such a distance from the flange B of the bracket B that the said flange will also mesh with the teeth of the locking-wheel when it is depressed for the purpose of making an impression, thus securing a proper alignment of the work. WVhen said wheel is elevated for the purpose of rotation to select characters, the flange B is below and out of mesh therewith. The detent E is always in mesh with the wheel. The object of the flange B is to preserve the alignment of the printed characters when once the locking-bracket B has been adjusted by means of the screw B in the slot B.

The next portion of the machine which will be described is the inker and deviccs for op erating the same. At the lower end of the spindle 1) is pivotally secured in any suitable manner the inker-arm I, which at its pivoted end is provided with a downwardly-inclined lug, 1 and at its free end is provided with a removable inking-pad carrier, 1. Between the free and pivoted ends of the inkenarm 1- is attached thereto a coiled spring, 1", the opposite end of which is secured to a standard, J, mounted on the base A and located in rear of the bracket B and beneath the type-wheel or printing-disk. This standard has an in clined lug, J, which operates in connection with the inclinedlug I of the inker-arm when the spindle is depressed to produce a partial rotation of the free end of the inker-arm in one direction, and when the said parts are elevated by the action of the spring D on the spindle the spring 1* retracts the inker-arm to its normal position, which is or may be below and in contact with V the printing-characters and above the printing-field of the machine.

The inking-pad K consists of any absorbent material charged or impregnated with an ink, and this pad is secured to an arm, K, projecting from the body of the ink-pad-carrying device 1 which body is formed as a sleeve, which, by means of a handle, I may he slid upon or removed from the free end of the inkerarm I, the latter being reduced to enter the sleeve, as clearly shown in Fig. 10.

The printing disk or wheel is formed separately from the lockingwheel, and secured thereto by screws F.

The printing-eharacters are formed on 2. depending flange, F, at the periphery of the disk, and inside of said flange is formed a series of space-varying elevations and depressions, F", each in height or depth being eX- actly proportioned to the printing-character immediately adjacent thereto.

The whole printing-disk is preferably formed as a stereotype or eleetrotypethat is, the characters and the variable spacing projections and depressions F are formed in one piece, so that by simply removing the screws F the printing-disk may be removed and another substituted therefor having a different style of type with their proper spacing devices.

\Vith the printing'disk of the character just described secured to the locking-wheel, the construction and operation of the feeding devices may be readily understood. In rear of the bracket, and beneath the type-disk, there is mounted upon the base a tubular standard or bracket, M, through which and the base a rod, N, passes downwardly into contact with and resting upon a rock-arm, O. Said rockarm projects from a rock-shaft, O, which extends beneath the carriage and across its path, being supported in brackets 0 By referring to Fig. 8 it will be seen that the rock-shaft O provided with another rock-arm, which extends vertically from the shaft, is projected laterally, and is provided at its end with a check-pawl, 0. Near the upper end of the vertical portion of the arm 0*, as at O, is pivoted an operating-pawl, P, which is projected beyond its pivot in an irregular or cam shape, as at P, which rides upon a p rojection, 1, of the base A. A spring, P, serves to throw the pawl P upwardly into contact with the rack when not otherwise affected. I

Q represents the rackbar, secured to, or it may be formed as a part of, the carriage. Having these elements in mind, it will be seen that when the rock-arm O is depressed the checkpawl O is removed from contact with the rackbar by reason of the oscillation of the rockshaft 0, and that for the same reason the pawl P is caused to move to the right and mesh with one or several teeth in the rack-bar, in accordance with the extent of the depression of the rock-arm 0. 111 this instance the parts are so proportioned that the greatest depression of the rock-arm 0 causes the pawl l? to pass over six teeth of the rack-bar, and by regulating the depression of said arm 0 said pawl may be made to take either one, two, three, four, five, or six teeth. After being so depressed the coiled spring R, eonnccted with the bed A and arm 0 serves to move the carriage and the feed devices and to elevate the rock-arm A for another depression. Now, it will be seen that by depressing the impression-lever H the space-varying devices of the type-disk are brought into immediate direct contact with the upper end of the rod N. If such space-varying device be an elevation, (as with a letter requiring a comparativel y broad printing-field,) the rod N will be depressed to a greater extent than in case of a depressional spacing device, (which would be deepest when the letter i, for example, is to be printed,) when said rod is depressed to a less extent, so that the number of teeth taken by the pawl I is directly controlled and the feed of the entire carriage is completely regulated by the space-varying devices themselves, and the entire operation is accomplished by force traveling in substantially a straight line from the impression-lever downward.

In Fig. 2 I have indicated a spacing-key, S, which is connected with a lever, S, having aa projection, S adapted to be brought into contact with the rock-arm 0, said lever being fulcrumed in a lug, S depending from the base A.

To avoid the provision of the several parts just mentioned, I may mount upon the rod N a bracket, T, as shown by dotted lines in Fig. 2, which bracket may pass through a slot, T, formed in the tubular standard or bracket M. Said bracket would be provided with a but ton or key, to facilitate its operation. By this means a depression of the bracket T would cause a movement or feeding of the carriage without the impression of a type upon the paper.

The carriage is adapted to ride in ways V, formed in the base, said carriage comprising a base and end brackets, W, in which is mounted the platen or roll \V, onto which the paper is guided by a plate, XV, secured to the rear edge of the carriage by screws l or otherwise. A guide-rod, W is pivotally mounted in one of the brackets W by being bent at a right angle to its length and entered into an aperture formed in the bracket, a spring, retaining the rod in the aperture, and yet permitting the free end of the rod, which is pro vided with a handle, \V, to be raised vertically and to be moved within certain limits horizontally away from the roll \V, as indicated by dotted lines at the left of Fig. 1. The free end of the rod is maintained in a recess in the bracket V at the right end of the carriage by means of a spring, W so secured as to bear against the side of the rod.

The usual pawl and ratchet, VVSJLLG employed to determine the line-spacing of the work.

The paper is introduced at the rear of the machine by passing it between the roller and the plate \V", and by also passing its front end under the rod XV, which serves to keep the paper in contact with the uppersurfaee of the roll.

To regulate the length of line printed, holes Z are formed in the base, and a peg or pegs are inserted in said holes, so that as the carriage advances projections Z thereon will come in contact with said peg or pegs. The rack-bar Q extends from end to end of the carriage and enters slots Q, formed in the .IOO

brackets WV of the carriage and at the lower edge thereof. A screw, Q the head of which is wider than the slot Q, is seated in the end of the rack-bar Q. Now, it will be seen that each of the ends of the raclr-bar being thus connected with the carriage, all that is necessary in order to remove the rack-bar is to loosen one of the screws Q (see Fig. 2,) or, if it be desirable to adjust the rack-bar longitudinally upon the carriage, one of the screws .may be loosened and the other tightened.

Furthermore, it will be noticed that the teeth of the rack-bar are above the plane of the feet of the brackets, so that when the carriageis removed from the machine and placed upon a desk or table the teeth of the rack-bar are preserved from inj ury,as the carriage rests upon its feet, while the rack-bar is elevated above said feet.

By reference to Fig. 9 it will be seen that the standard or stud J is provided with an impression-adjusting screw, J This screw projects upwardly above the stud, and serves as an abutment against which the printingdisk strikes at the time the impression is made. By a proper adjustment of the screw vertically the pressure of the printing-disk upon the paper may be regulated so that no more than sufficient force or impact of the type against the paper will take place than is required to give a clear impression.

Having thus fully described my invention and its operation, what I claim is 1.
