SPECIFICATION forming part of Letters Iatent No. 529,208,dateot November 13, 1894.

Application filed December '7, 1892. Serial No. 454.365. (No model.)

To aZZ whom it may concern.-

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

This invention relates to certain new and useful improvements in type writing machines, and among the various objects in view are the following: to provide for the changing of the character say from upper to lower case or vice versa, without moving the earriage or platen; to provide simple 'means for permitting this change; to economize in space occupied by the ink padaswell as in the pad itself; to provide a movable ink pad actuated to change its position at predetermined intervals; to so mount the paper roller or platen that it can be revolved in either direction at any and all times without moving the dog or any other part; to so mount the dogs that they can be thrown out to permit of turning of the paperroller or platen at will to adapt the machine for writing upon ruled paper where the space between the lines does not conform to the feed of the roller in the usual way; to furnish an improved paper guide which shall have sufficient resiliency in all directions to properly hold the paper and atford pe fect feed when several sheets are employed or in case a wrinkle or other unevenness occurs in the paper; and to provide improved means for holding the paper table in either of its positions.

It has for a further object to improve generally the make-up of the machine whereby it is rendered more efficient, more easily operated, and less liable to become injured from careless handling.

Other objects and ad vantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which,with the lettors of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side elevation of a portion of i a type-Writing machine with some of my present improvements shown in side elevation and parts in section, the base of the machine also being shown in section.

Like letters of reference indicate like parts throughout the several viewsin which they appean All of the figures are upon the same scale, except Figs. 6 and 12 which are somewhat enlarged. r

All of the improvements hereinafter specified need not be present in the one machine; any one or more of them may be employed without the others; parts may be used Without the whole,and modifications in detail may be' resorted to without departing from the-spirit of the invention or sacrificing any of its advantages.

Referring now to the details of the draw ings by letter, A designates the base of the machine of known construction; A, the universal bail; A the platen; A the paper-table and A one of the key levers. The key levers are pivoted at one end as at a and are arran ged to actuate the universal bail in the usual manner and as seen in Fig. 1. The universal bail is pivoted as at a, see Fig. 1, to a depending arm or lug, or any fixed part, and may be of any approved form.

A is a substantially horizontal part pivoted at its front end as at a to some fixed part of the machine, as a depending portion or lug a. as seen in Fig. 1 beneath the top of the base and at its other end it is connected with the universal bail in any suitable manner so as to move therewith. Upon this arm A is mounted a shaft or rod at which is mounted thereon so as to be given a partial revolution in its bearings, which in this instance are shown as simple staples or eye bolts 0. through which the said shaft or rod passes. The outer end of this rod or shaft is turned at substantiallya right angle toits length as seen at a in Fig.1 to form a convenient means whereby it may be given the necessary rotary movement and its other end is turned upward as seen at ofand thence horizontally to form the short arm a as is best seen in Fig.1 which short arm or hook is designed to be engaged in a hole or other provision in the lower end of a vertical arm or bar which will soon be described and the object of which will be set forth. This bar is mounted to slide vertically through an opening a. in the base as seen in Fig. l and is held normally at its upward limit by a spring B connected at one end to said bar B and at its other end in any suitable manner to the plate A of the machine as seen in Fig. 1. This bar is a part of or is securely alfixed to a curved plate B arranged in front of the part A and provided with vertical slots b to receive pins 1) or other means upon the plate A to guide the curved plate 13 in its vertical movements. There may be as many of these guiding pins employed as may be deemed necessary. This plate B has at its upper end a series of horizontal flanges B which are separated by suitable openings or passages 12 wide enough to permit of the passage of the lateral portions 0 of the arms 0 as hereinafter described. Each flange is provided with a depending tooth b as seen in Fig. l. The front edge of the lower wall of each passage is inclined to the front of the machine as seen in Figs. 1 and l. The bar B has near its lower end an opening b to receive the hook a of the rod A as indicated in Fig. 1. When this hook is engaged in said hole, the rod A being carried by and movable with the arm A which moves with the universal bail, at each depression of a key-lever the bar B will, through the medium of the devices above described, be depressed. As soon as pressure is removed from the key lever the bar B'and of course the plate B carried thereby will be returned to their normal positions being aided in such movement by the spring 13.

C is a type-bar provided with two characters c c and this type bar is pivotally connected at its forward end as at c with the elbow lever C which is pivoted at its elbow upon a horizontal pivot 0 the short arm of the lever being pivotally connected with the key-lever by a ligament (I which passes through an opening 0 in the base as seen in Fig. 1. A stop 0 is provided to limit the downward movement of the type bar. The type bar is pivotally connected with the arm 0 pivoted at c at its lower end, the connection between this arm 0 and the type bar being a link or ligament C which is shown as curved but not necessarily of that shape. This arm 0 is provided with a lateral portion or offset 0 which is formed with a notch c as seen in Fig. 1. A stop (I is provided to limit the backward movementof the arm In the foregoing description I have referred to but one key lever and one type bar with their connections but it will of course be understood that all of the key levers and type bars are connected in a similar manner and designed to operate in the same way.

The operation of the parts hereinbefore described is as followsz-Ordiuarily the rod A is turned as shown by dotted lines in Fig. 1 so that its hook portion is out of engagement with the hole in the rod or bar 8' so that when the key lever is depressed the bar 13' and its plate B are not actuated and thus the depression of the key lever moves the type bar, the arm C, and connection G into the position in which they are shown by dotted lines in Fig. 1, moving the type from the inking pad and throwing the lower case or type c against the platen A. When pressure is removed from the key lever the parts return to their normal position. Shown in fulllines. When itis desired to write caps or upper case characters the rod A is turned so as to engage its hook portion in the opening in the bar B so that when a key lever is depressed the bar 13' will be depressed therewith through the medium of the bail A, bar A and connections hereinbefore specified. The bar B being moved downward moves therewith the plate B so that the lateral por tion 0 of the arm 0 being relieved of its abutment on the plate B is free to move through a corresponding opening b of the plate B until it engages the plate A. This increased movement permits of further move ment of the type bar 0 so as to bring the character 0' against the platen. (Fig. 13.) As the arm 0 is moved rearward the abutment B being depressed, the extension 0 of said arm enters the passage b in the said abutment and a tooth b enters the notch in the extension 0 of said arm and the type bar is locked against a sliding movement on the ink pad and upon its return movement against a sliding movement on the platen,

thus preventing blurring, as the initial movement of the type end of the type bar must be in a vertical direction away from the inking pad or the platen but it is moved horizontally back to its normal position. The notch in the extension of'the arm 0 serves in conjunction with the depending tooth b of the abutment to thus prevent the blurring. The inclined portionb of the plate B engages the under side of the lateral projection of the bar 0 and gradually returns it to its position as the plate B is returned to its normal position by the spring B after pressure is removed from the key lever. I

D is the ink pad which consists of an endless band of suitable material mounted upon rollers D carried by shafts supported in a table or plate D carried by the standard B which are carried by the opposite bars D to which the spacing key D is connected. D is a ratchet on one of the shafts d which carries the roller and D is a detent carried by one of the side bars D and arranged to engage with the teeth of the ratchet to prevent rotation of the ratchet D during the forward movement of the arm D carrying the ink ribbon and its appurtenances, while D is a pawl secured to some fixed part as forinstance a portion D of the frame D of the machine as seen in Figs. 11 and 12. By this construction each time the spacing bar is depressed the ratchet is moved one notch and. consequently the inking pad is moved a corresponding distance.

Referring now to Figs. 5, 7 and 8 E designates my improved platen paper guide which I form of spring material and support the same resiliently. It consists of a portion which encircles the platen for any required or preferred portion of its circumference preferably about twojthirds as seen in Fig.'6 and provided with one or more arms 6 formed intogral with the same by slitting or otherwise and these arms provided with perforations e to receive the screws or other means a by which they are secured to a portion e of the carriage. By this construction the guide is resilient at all points and being also resiliently supported it will yield at the proper point or points to compensate for, numerous thicknesses of paper or for any wrinkles in the paper or the carbon sheet employed and the paper will be fed evenly and smoothly. The paper guide may be formed with one or more legs or supports as. may be foundinost desirable. Both forms are seen in Fig. 7.

A" is the paper guide roller. The paper table A is mounted for partial rotation in the arms or end pieces A of the carriage frame as seen in Fig. 3.

The preferable manner of mounting the paper table is as follows: Upon the upper face thereof at the end are secured the lugs F in which are held preferably by screws f the polygonal ends of the journals F which journals or pintles are supported in the-said end pieces A and are surrounded by collars f and f, the one on the left in Fig. 3, being fast on the end piece, their outer endsbeing provided with a hole to receive a suitable instrument for giving the same a partial rotation when desired. F are springs surrounding these journals or pintles outside of the collars with one end of one connected to the collarf and the other end held in the journal or pintle in any suitable manner as for instance by being inserted in a hole therein as seen in Fig. 3. When it is desired to adjust the tension of the spring all that it is necessary to do is to remove the screwf, remove the polygonal end from its seatin the lug and then give the journal a sufficient rotation and then replace the said polygonal end and the screw to hold the same in its adjusted position.

The collar f at the right hand side of the machine is provided upon its upper portion with a notch f as seen in Figs. 3 and 9 and loosely pivoted as upon a pivot f On the end plate A of the carriage frame is a gravity pawl F the short arm F of which is provided with a projection or detent f as seen best in Fig. 9. The spring f at its end has one end connected to the end piece A and the other to the journal as shown. Normally when the paper table is in its substantially horizontal position as seen in Fig. 9 this notch in the collar which is fast upon the journal of the paper table is uppermost and free of the projection on the gravity pawl. When it is desired to turn the table up into the position in which it is shown in Fig. to make corrections or for other purposes all that is necessary to do is to grasp it with the fingers and move it in the direction of the arrow in Fig. 9. As it reaches the vertical position as seen in Fig. 10 the projection on the short arm of the gravity pawl falls into the notch of the collar and automatically locks the paper table in its elevated position. This brings the paper more nearly into a vertical position when it can be better reached by the operator and a better erasure made with greater ease and without the necessity of the operator leaving his seat. To return the table to its normal position all that is necessary is a slight upward pressure on the under side of the long arm of the pawl which disengages the projection of its short arm from the notch in the collar when the spring F will throw it into its horizontal position.

The platen'journals are removablyheld in their bearings on the carriage in any suitable manner which it is not deemed necessary to describe in this application. Upon one end of said journal G is a ratchet G with which engages the pawl G pivotally mounted as at g on the rock arm G pivoted at g to some part of the carriage frame and its other end having pivotally connected thereto as at g the arm or link G which is pivotally connected with the thumb lever G which is pivoted at its elbow as at g to a projection G on the base of the carriage frame so that movement of this lever or thumb piece moves the pawl and causes it to engage the ratchet and thus turn the paper roll.

11 is the thumb piece for throwing the feed pawls out of engagement with the rack bar to permit of the return of the carriage.

The arm G is ofi'set as seen in Fig. 4c and is provided with two steps or notches g and in order to limit the throw of this arm to enable the pawl to turn the ratchets one or twb teeth at a time as may be desired, I provide a lever I pivoted att' and its depending portion 1 is shown as having a lug 2" adapted to engage one or the other of said steps and provided with a pin 2' engaging a shoulder 71 on the detent J. The said detent is adapted to engage the ratchet and has a projection or extension j as seen in Fig. 4 upon which rests the end of the pawl G so that the latter is normally held out of engagement with the teeth of the ratchet to permit of rotation of the paper roller in either direction when desired. The lever I has a portion 1 extended below its ivot and formed with notches 71 11110 one or P the other of which is adapted to engage the point of a spring K secured on the under side of a detent J as seen in Fig. 4. In order to throw the detent entirely out of engagement with the ratchet to permit of free turning of the paper roller as for instance as when it is desired to write upon ruled lines I mount in the end of said detent an endwise movable horizontal pin K normally resting against the part L and havinga head and the shank of which is surrounded byaspring K. hen theleverI is pressed toward the operator the pin 71 engages the shoulder i of the detent and throws the engaging portion thereof outward sufficiently to permit the pin K to be pressed endwise by the spring K and engage against the outer face of one of the pivoted devices L of any suitable construction which serves to hold the journal of the paper roller in its bearing.

Modifications in detail may be resorted to without departing from the spirit of the invent-ion or sacrificing any of its advantages.
