SPECIFICATION forming part of Letters Patent No. 540,078, dated May 28, 1895.

To aZZ whom it may concern:

Be it known that I, 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 has for its objects among others to provide simple and efficient means for changing the inking pad or movingit at each depression of a key lever, with provision for automatically reversing the direction of movement thereof.

It has for a further object to provide novel devices andmeaus for changing from upper to lower case and vice versa. I aim further at lmprovements in the details of construction, as will all be more particularly hereinafter pointed out.

Other objects and ad vantages of theinven tion 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 letters of reference marked thereon, form a part of this specification, and in whicl Figure l is a detail in top plan showing suificient of atype-writing machine to illustrate my present invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a detail perspective, on alargerscale, of theinner plate or are removed. Fig. at is a front elevation, with parts broken away, of the inkpad support and the shifting mechanism. Fig. 5 is a bottom plan of the ink-pad on a larger scale. Fig. 6 is a top plan of the shifting mechanism and the ink-pad support. Fig. 7 is a diagrammatic view showingthe manner of pivoting the type-bar. Fig. 8 is a similar view showing the parts in another position. Fig. 9 is alike view showingthe parts in still another position.

Fig. 12 is a. detail in perspective showing the means of moving the arc-shaped plate.

112.11%. 504,999. (No model.)

Fig. 13 is a perspective detail view of the front arc-shaped plate. Fig. 14 is a plan of the rear arc-shaped plate, showing the alternate arrangement of its slots.

Like letters of reference indicate like parts throughoutthe several views.

Referring now to the details of the drawings by letter, AYlesignates the frame, A the carriage, A the carriage rod, and A the platen, all of known or approved construction.

Secured near the front of the frame is the arc-shaped plate 13 from the front of which rises the flange B which is provided with a groove or channel I; and with radial slots or slits h.

C are the type-bar arms which are pivotally mounted in this flange, preferably upon a wire 0 located and held in said groove or channel and forming the fulcrum for said arms, and the curved portion 0 of the arms working in the slots or slits as seen in Figs. 1, 2 and 7. The arms G each have a perforated lug or extension 0 provided with a perforation in which is held one end of the rod or link C which is connected at its other end to the key lever C which is mounted in the frame for movement in the usual manner.

0 is a spring connecting the rear end of the key lever with a fixed portion of the frame in the ordinary manner.

D is the universal bail mounted in the usual manner for actuation by each and all of the key levers.

The upper end of each arm 0 is pivotally connected as at c with one end of a type-bar E which type-bar carries a plurality of type E, in this instance shown as two in number. Each type-bar is provided with as many notches c as there' are type on the bar, in this instance two, and these notches have a forwardly inclined wall 6 as shown best in Figs. 7, 8 and 9. These notches co-operate with the lock-plate E which is secured in 0perative position between the platen and inkpad as seen in Figs. 1 and 2 and which is provided with the arc-shaped upwardly-extending teeth as shown in Fig. 1, there being fourteen teeth and each adapted to receive three type-bars to lock the same. In order to adaptthe type-bars for co-operation with the lockplate in this manner I. form 010 of the typebars without offset, or of a single thickness, as shown in Fig. 8, and the type-bars upon each side thereof I make with an offset E to either side for the purpose of permitting the type-bar to reach the printing point in a straight line, while the locking portion of the bar is made to enter the lock-plate tooth by reason of the offset. This offset is formed either on the bar or it may be by a plate secured to the type-bar, such form being shown in Fig. 11. In Figs. 7 and 9 this offset is seen at E and this offset alternates, that is, upon the one on the right of the center type-bar of each set itis on one side, and on that 011 the left it is on the other side. Thus each set comprises a bar without offset and two offset bars.

The rods or links 0 work through vertical slots b in the plate B as seen in Fig. 2, while rising from the plate 13 near its rear edge is the arc-shaped plate F which at its upper end terminates in a horizontal flange F which is provided with radial slits or slots fas seen best in Fig. 1. The upper face of this flange is provided with a surrounding channel or groove f in which is located the wire F while upon its under face is a channel or groovej in which is held the wire F as seen in Figs. 7, 8 and 9. The slits or slots in the plate F extend in its vertical portion below the bottom face of the flange F as seen in Figs. 7, 8 and 9 for a purpose which will soon be mad-e apparent.

G is a link pivotally connectedat one end with the type-bar between its ends as seen at g while its other end is of peculiar construction. It is formed with a double lateral curved portion which extends substantially at a right angle from the body portion of the link and this portion G is formed with the two slots g and 9 extending one into each curve and.v

each open-ended as seen in the various views of the drawings. The curved faces q and g serve as the bearings upon which the link moves, and, in conjunction with the wires F and F constitute the fulcrums of the same. As shown in Fig. 7 both of the wires are within the circle described by the curved end portion of thelink in its movements. In Fig. 9 the relative positions of the parts have been changed, by mechanism soon to be described, so that one of the wires is within the circle while the other is outside the circle, as will be readily seen upon reference to said Fig. 9.

In Fig. 7 the type-bar is shown in its forward position, that is, that which it assumes when not printing, while in Fig. Sit is shown as in its other position, that which it assumes when the type is in position to print on the platen.

H is the movable arc-shaped plate. It is held to the vertical portion of the plate F by suitable means allowing it to have the necessary movement. For instance, in the present case, it is shown as held in place by screws h which pass through horizontally elongated slots h in the vertical portion of the plate H and are screwed into the Vertical portion of of the arrow in Fig. 1.

the plate F. See Fig. 7. This plate 11 is provided at its upper end with a lateral portion H which has the curved ribbed and slotted channel H as shown best in Fig. 3 and in which the wire F lies and beyond this curved channel with the vertical shoulder k as seen in Fig. 3. The curved channel is formed with the radial slots h and the raised portion in said shoulder is formed with radial channels or slots h the slots or channels h and 7% alternating as seen in Figs. 3 and 14. Upon the upper face of the lateral portion H are secured the blocks or stops or fulcrum seats I which may be secured thereto in any suitable manner as for instance by the screws as shown, there being designed to be one of these over each partition or wall between two slots or channels h. in the portion H and these blocks have their outer ends formed with an undercut curve 7; as shown best in Fig. 3, which is the same curve as that of the channel H as shown best in Fig. 3 where one of the said blocks is shown in position.

The plate H is mounted for movement in the arc of a circle and for this purpose I, by preference, employ a special key I seen in Fig. 1 and which is suitably pivoted beneath the frame and beneath the universal bail, and from this lever projects the vertical arm I as seen best in Fig. 1 which is adapted to engage the arm t' projecting from the end of the plate H as seen best in said Fig. 1 so that when the special key lever is depressed this vertical arm will engage the arm 2' and move the plate H in the direction of the arrow in Fig.1, the parts being designed to be returned to their normal position when the key lever is released by a spring 1' secured preferably to the vertical end portion of the plate F and arranged to bear against the arm i as seen in Fig. 1.

With the parts constructed and arranged substantially as above set forth the operation of this part of the invention is as follows: Normally the parts are in position to print only lower case letters or characters. With the parts in this position the depression of a key lever will bring the parts into the position in which they are shown in Fig. S,the link G turning on the wire F as its pivot which works in the slot g of the curved portion of the link. In this position the curved end of the link works in the radial channels or slots 71. of the flange of the plate H and the undercut curve of the blocks I serve in conjunction therewith to determine the movement of the link and consequently of the typebar. When it is desired to print an upper case character the key lever l is depressed which brings the vertical arm 1 against the arm i and moves the plate H in the direction This shifts the relative positions of the plates F and H so that the radial slots of the flanges of the said plates are coincident as seen in Fig.1 where the parts are supposed to be in such position, the special key leverhaving been depressed. Now

ICC

a depression of a key lever will throw the typebar over into theposition in which it is shown in Fig. 9 the plate H having been moved so that the blocks I are no longer in the path of the links and the fulcrum or pivot is changed from the wire]? to the wire F as seen in said Fig. 9 andthe extreme curved end of the link rides upon the upper curved face of the channel H that is, upon the upper faces of the partitions between the channels or slots 7"? and these being coincident with the slots or channels 72. the link is not restricted in its movement by the block I but moves through the slot or channel 72, which gives it the additional amount of throw to allow it to so move that the other character on the type-bar is brought into the proper posi tion over the platen. As soon as pressure is removed from the key lever I the spring 2' returns the parts to their normal position.

The mechanism for movingthe ink-pad is shown detached in Figs.'4, 5, and 6', and. in On. an extension position in Figs. 1 and 2. A of theframe of the machine are mounted the upright hollow standards J within which are confined springs J'as seen inFig. 4 which find a hearing at their lower ends upon the 4. To the rear face of these standards is attached a plate j upon which is secured the lock-plate-E as seen best in Fig. 2.

K are posts mounted to reciprocate vertically within the hollow standardsJ as seen in Figs. 4 and 6, and resting upon the springs J. The upper ends of the posts are provided with enlarged heads in which are formed slots 70 as seen best in Fig.6 which are formed upon curved lines as shown for a purpose which will soon be explained. These posts are connected by a cross plate K which works in slots in the adjacent sides of the standards J, the cross plate being secured tothe postsin any desirable manner, as by the screws 70 Seen in Fig. 4. This cross plate and consequently the posts are drawn downward by means ofa .rod, link or analogous connection L which is connected at its upper end with a transverse screw orprojection as seen best in Figs. 2 and 6, while its other end is connected with the universal bail as seen in.Fig. 2. This projection Z may be of any form. The cross-plate is limited in its .upward movement by a lateral pin or projection l projecting from the plate or bar M which is secured to the front face of the standards J as seen in Figs. 2, 4, and 6.

Pivotally mounted on the plate M is the oscillating lever N which is pivoted at its center as seen at n and its two arms extend substantially horizontally as seen best in Fig. 4 and each is provided between its end and pivot with a laterally projecting pin or stud n as seen best in Fig. 6. This lever is held at a distance from the plate M by a spacing block or collar N as seen best in Fig. 6 to provide space between the saidplate and leis a spring 19 all as shown in Fig. 4..

Q is 1theIink-pad carrier.

pawls being slightly up-turned as seen in Fig. 4 and pointed to engage with a rack-bar soon to be described. The lever N has a portion N depending from its center as shown best'in Fig. 4 and the bottom face of this portion is formed with the inclined walls 97. oppositely disposed as seen in Fig. 4 and between these inclined walls is a slight projection 01 as is also shown in said Fig. 4. Projecting from the plate M at a point below and in vertical line with the pivot of the lever N is a stud P in which is mounted for vertical reciprocation abolt P the upper end of which terminates in a conical head 19 as shown best in Fig. 4 and between the shoulder of the head and thetop of the stud, around the bolt It is provided upon its upper face with a holder Q for the inkpad which may be of any desired character and held in the holder in any suitable manner.

upper ends of the screws or boltsjwhich are threaded into the standards as shown inFig.

Q is the ink-pad. i

The carrier, holder and pad are arc-shaped as seen in Figs. 1 and 5, and upon the under side of the carrier is a rib or flange g which is provided with a groove or channel gas seen best in Fig. 4.' This rib or flange is fitted to move freely in the curved slots is of the heads of the posts K as shown in Fig. 4, andthe carrier and its attached parts are prevented from vertical displacement by means of screws g held in the heads of the posts and entering this groove or channel so as to allow of movement of the carrier in the slots of the heads of the posts but not vertically with relation thereto.- To remove the carrier these screws are removed.- Upon the inner face of the rib or flange q of the carrier is secured a rackbar R the teeth of which are very fine as seen in Fig. 4, and upon the outer face of this rib or flange is the plate S which is rendered adjusted by means of the slotsstherein through which pass the securing screws as seen in Fig. 4, and this plate has depending therefrom the lugs or projections S as shown in Figs. 2 and 4.

The operation is as follows: One ot the pawls O or O is at all times in operative contact with the rack bar R, while the other hangs down in the position shown in Fig. 4. At each depression of a key lever the crossplate K which carries the ink-pad actuating mechanism is drawn downward and the inkpad carrier is moved one tooth to the right or left, according to which pawl is in engage ment with the rack. Each depression of a key lever moves the carrier in the one direction until the projection S at theend of the plate S toward which the carrier is moving comes in contact with the pin or projection n on the ,d ouble-armed lever N, which serves to throw that end of the lever downward and the other end up. This reverses the pawls, that is, the one that was before up falls down and the other is thrown up. As the lever is shifted the conical head of the bolt P isautomatically shifted into contact with the inclined wall upon the opposite side of the teat 11 Thus the ink-pad is automatically moved at each depression of a key lever and the reversal of such movement is also automatically governed.

As shown in Fig. 4, the projection S at the right is vertically in line with the pin n so that upon the next depression of the carrier the said projection S will engage the pin n and perform the function stated, it being understood that, as shown in this view, the carrier is in its elevated position but the amount of movement of the carrier vertically is sh own to be more than enough to bring the projection S into contact with the pin n.

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