TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 435,654, dated September 2, 1890.

Application filed March 20, 1889. Serial No. 304,030. (No model. I

To all whom it may concern.-

Be it known that I, OHARLEs II. PERRY, of Oneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Type-Vriting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of typewriting machines in which a printing-plunger has a convex printing-face, and is set to bring the different types into their printing position by key'levers operated by a key-board.

My present invention consists in an improved construction and combination of parts, rendering the machine more eflicient and more convenient in its operation; and the invention also consists in certain peculiarities of auxiliary devices employed in connection with the aforesaid parts, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a top plan view of a type-writing machine embodying my invention. Fig. 2 is a rear elevation of the same. Fig. 3 is an enlarged vertical transverse section on line a: at, Fig. 1. Figs 4 and 5 are elevations of opposite sides of the machine. Fig. 6 is a front elevation of the same. Fig. 7 is an enlarged detached inverted plan view of the key-board. Fig. 8 is a vertical longitudinal section on line y 3 Fig. 7. Figs. 9 and 10 are vertical transverse sections, respectively, on lines O O and Z Z in Fig. 7. Fig. 9 represents sectional views of the attachment of the buttons to the different keylevers. Figs. 11 and 12 are respectively detached side and rear views of the printingplunger. Fig. 13 is a vertical longitudinal section of the printing-plunger on line U U, Fig. 12. Fig. 1+1 is a sectional view showing the operation of the push-pin on the printingplunger. Figs. 15 and 16 are top plan views of the printingplunger in the conditions shown in the previous figures. Figs. 17 and 18 are enlarged side and longitudinal sectional views of one of the spools which carry the ink-ribbon, and showing the means for imparting the desired tension to said ribbon. Fig. 19 is an enattachment. Fig. 20 is a face view of the printing-plunger. Fig. 21 is an enlarged verti cal transverse section on line 1; 1 Fig. 3; and Fig. 22 is a plan view of the bank of pushpins.

Similar letters and figures of reference indicate corresponding parts.

A represents the base or main supportingframe of the machine, 011 the top of which frame is mounted the platen B, which is preferably of the form of a short straight bar sliding longitudinally in a groove or guide It, extending rectilipearly lengthwise of the top of the aforesaid frame and parallel with the track of the carriage. Said platen is thus maintained in a uniform plane. A suitable pad h is secured to the top of the said sliding bar to receive the concussion. is only as large as the largest letter or character to be printed, and the paper and ink-ribbon being supported by that extent of surface only, no impression is made 011 the paper, the surrounding surface of the paper being maintained perfectly clean.

Parallel with the platen or its guide It is a track D, preferably of the form of a straight bar secured at opposite ends to the frame A, and on this track is mounted movably longitudinally a carriage C. To this carriage is attached a horizontally-extended yoke i, with which is connected the platen B by a rod 2', so that said platen is compelled to move synchronously with the carriage. In order to securely retain the carriage on its aforesaid track without incurring friction in its movement, I provide said carriage with rigid perforated ears j j, and pivot thereto anti-friction rollers j j, which bear on the track-rod at three or more points of its circumference. The carriage is further supported on another track D, parallel with the track D, by means of a shaft 70, journaled in the carriage horizontally and atright angles to the tracks, and having pivoted to one of its ends a roller which rides on the track D.

On the carriage O is hinged a verticallyoscillatory arm E, the free end of which is over the platen and sustained normally in an elevated position by means of a suitable larged "iew of one of the push-pins and its spring or springs F, connected at opposite This pad ends, respectively, to the carriage and to the arm E. V I

To the under side of the free end of the arm E is connected the printing-plunger G by a universal joint or gimbals G. The lower end of this printing-plunger has aflixed to it a convex type-plate I, which has formed integral with it, or otherwise firmly attached to it, different fields of types arranged in approximately straight parallel rows across the face thereof, as shown in Fig. 20 of the drawings. To the plunger is pivoted a tumbler c, to which is coupled one end of a rod L, the opposite end of which is swiveled to the end of a brace L, which is rigidly secured to the carriage C underneath the arm E.- Said tumbler is formed with a catch 0, and to the plunger is pivoted a latch cl, having a hook d adapted to engage the aforesaid catch. A spring g, attached to the plunger and bearing on the latch, holds the latter in contact with the tumbler.

When the machine is at rest and the arm E raised, the latch cl is engaged with the catch 0 of the tumbler c, and the brace L and its couplings L draw the upper end of the printing-plunger G toward the front of the machine or toward the carriage O, as represented in Fig. 3 of the drawings. A V-shaped guide E", attached to the under side of the arm E, receives the upper end of the plunger in its aforesaid forward-tilting movement. The upper end of the aforesaid printing-plunger is provided with an axial channel I) and a diametrical slot b, and has extending from it radial guides a a, which are disposed divergent from each other toward the rear of the machine.

The upper endof the hereinbefore-described latch d is provided with a laterally-proj ecting lug d", which is entered into the slot 1) of the printing-plunger. Said lug is provided with a notch e on its top, and to the top' of the plunger G is pivoted a dog f, which has a tongue entering the notch e, as shown in Figs. 15 and 16 of the drawings.

The free end' of the arm E is formed with a ring E central over the universal joint G of the printing-plunger, and in this ring, concentric therewith, are firmly secured two concavo-convex plates 7 7, disposed one above the other, with their convex sides upward, and with a space between them. These plates are provided with perforations which, taken in pairs one on each plate, are in lines convergent toward the center of oscillation of the printing-plunger G or center of the universal joint G. Through the space between the aforesaid plates and through the perforations thereof extend a bank of push-pins S 8 8, &c. Each of said pins has affixed to it directly under the upper plate '7 a collar 8,

as best seen in Fig. 19 of the drawings, and a spiral spring 9, surrounding the pin and pressing with one end on the lower plate 7 and with opposite end against the under side of the collar 8', serves to sustain the pin in its raised position, and when in this position the lower end of the pin is flush with the under side of the bottom plate 7, while the upper end of the pin projects above the top plate 7.

Upon the free end of the arm E or ringE thereof is mounted a key-board, which is connected thereto by longitudinal rods Z Z, connected to cars Z Z on the front and rear of the key-board frame H, said rod passing through sleeves Z Z, rigidly secured to the ring E, said attachment allowing the keyboard to be shifted longitudinally for the purpose hereinafter explained.

Within the key-board frame H is a series of key-levers n n n, arranged parallel side by side and lengthwise of said frame'and hinged at one end to the same. Each of these keylevers has aflixed to its under side a button n, by which it rests upon the upper end of one of the push-pins 8, and from the top ofthe key-lever projects Verticallyastem which passes through a guide 0, formed on the keyboard frame, and to the upper end of said stem is attached the finger piece or key 0, which has marked upon it the letter or character designed to be printed by said key.

The operation of the printing plunger G by means of the described key-board is as follows: By depressing the desired key 0, the push-pin 8, which supports the key-lever of said key, is also depressed and caused to protrude from the bottom plate 7. A further downward pressure on the key depresses the arm E, and the movement of the latter causes. the brace L and rod L to throw the upper end of the printing-plunger G rearward. One of the guides at of the plunger coming in contact with the protruding lower end of the push-pin 8, guides said plunger into such a position as to bring the axial channel 1) thereof in range with the push-pin which enters said channel, as shown in Figs. 14 and 16 of the drawings, and when the plunger is in this position the type-plate I is caused to present to the platen a type corresponding to that marked on the key 0.' In entering the axial channel 6 the push-pin 8 crowds the lug d" radially out of the slot 1), and thereby causes the dog f to grasp the push-pin and at the same time also causes the latch d to release its hold on the tumbler c. The latter being thus liberated and allowed to turn on its pivot relieves the plunger G from the lateral pressure of the brace L, while the plunger is retained in its requisite angle by the push-pin 8, and pressed down to make its impression on the paper'lying upon the platen. 'After this is effected the operator allows the oscillatory arm E to rise automatically by force of the spring or springs F. In the ascent of said arm the tumbler drawn by the connecting-rod L turns backward on its pivot until the latch (1 again falls into the notch in the tumbler, which allows the upper end of said latch to return to its normal position and turn back the dog f and release the push-pin,

when the upper end of the plunger is drawn forward by the brace L and the connectingrod L to its original position.

When it is desired to operate the oscilla tory arm E without bringing the printingplunger in contact with the paper upon the platen, it is only necessary to depress said arm without applying pressure to any of the keys 0, the latch (Z being thereby left in engagement with the tumbler c, and thus the latter is locked on the printing-plunger G, so as to cause the same to be thrown with its upper end rearward by the brace L and its coupling L. A cushion 14, attached to the under side of the arm E, receives the said rearward thrust of the printing-plunger.

In order to allow the different fields of types on the printing-plunger to be brought into use when desired, I arrange the buttons n of the key-levers n H for the respective fields of types in straight rows crosswise the keyboard, as shown in Fig. 7 of the drawings. The key-board frame being mounted movably longitudinally on the arm E, as hereinbefore described, allows the key-board to be shifted, so as to bring the different rows of buttons at n into position to operate the subj acent-pushpins 8 8 S. v

To retain the key-board in its desired posit-ion, I pivot to one end of the key-board frame a lever J, of the form of a rectangular frame, extending along the sides of the keyboard frame and to the opposite end thereof, where it is provided with a suitable handle J for manipulating it. To the longitudinal bars of the lever J are rigidly attached latchplates J provided with a notch 10 in their center. To the ring E of the arm E are firmly secured catches K K, adapted to engageeitherthe notches 10 in the plates J J" r the ends of said plates, according to the pr tion into which the key-board is adjusted. Vf .ien engaged with the end of the latchplates, the cars l on the corresponding end of the key-board frame abut against the ends of the sleeves Z Z, and thus retain the keyboard in its position.

In order to prevent the buttons n it of the key-levers from dragging on the end of the push-pins 8 8 8 during the aforesaid shifting of the key-board, I attach to the lever J a rod m, which is extended across the under side of the key-levers and lifts the same when the said lever is raised to release the latchplates J from the catches K.

To the carriage 0, directly under the arm E, is adj ustably secured a stop M to limit the downward movement of the said arm, so as to obviate undue concussion of the printingplunger upon the platen, said stop being represented in the form of a set-screw inserted vertically in the top of the carriage and provided with a suitable pad or cushion on its top.

The arm E, with the described printing mechanisms attached thereto, is arranged to move longitudinally over the platen automatically with the operation of said arm by means of the following feed mechanism: Lengthwise of the bed or main supportingframe Ais extended and firmly seenreda rack N, parallel with the tracks D D. To the shaft k, which is journaled in the carriage horizontally and at right angles to the rack, as 11 ereinbefore described, is secured the feed-wheel or pinion p, which rides on the aforesaid rack. To said shaft is also rigidly attached a hub 76'', and a clutch-collarris mounted looselyon the shaft. To this clutch-collar is pivoted a clutch-lever s, which is provided with a gripping-bearing s, engaging the periphery of the hub as illustrated in Fig. 21 of the drawings. The free end of this lever is connected with the oscillatory arm E by a rod 8. A weighted lever O is extended rigidly from the clutch-collar r to turn the same in opposite direction from that imparted to said collar by the gripping-lever s. lVhen the oscillatory arm E rises from the platen the rod 8" draws the gripping-lever stightly against the hub 70" and turns the same. The shaft k turning with it, causes the pinion 1) by its engagement with the rack N to move the carriage O. In depressing the arm E the lever s is caused to loose its gripping hold on the hub k", and thus the carriage remains stationary during said movement of the arm E. At the same time the weighted lever 0 drops and turns the clutch-collar 0' into a position to allow the gripping-lever s to take a new hold on the hub during the succeeding ascending movement of the arm E.

In order to automatically regulate the motion of the feed mechanism to produce the various spacing required for the different widths of types, I attach to the clutch-collar r a clutch-tripping arm 1, extending therefrom in opposite direction to the weighted lever O, and to the ring E, or free end of the oscillatory arm E, I pivot the spacing-lever I, which is formed with a plate P, extending across the under side of the key-levers n n n and presenting its top edge to the same. This edge of the plate P is provided with a series of notches u a of different depths, so that in depressing the different key-levers they come in contact with the plate P during different distances of their movements. The notch under the key-lever which prints the letter I is deeper than the notch under the key-lever which prints the letter N, and the latter notch is deeper than the notch under the key-lever which prints the letter M, and in this manner the depths of the notches in the plate I are graduated according to the different widths of the letters to be print-ed by the key-lever over the respective notches, and the spacing-lever P is actuated by the different key-levers in correspondingly-varying degrees.

To the spacing-lever P is rigidly attached a downwardly-extended arm P, which has affixed to its lower end a clamp Q, and to the latter is connected longitudinally adjustably a rod orarm Q, which hasits free end transversel'y over the arm 15, which is attached to the clutch-collar r, as hereinbefore described. The movement of the spacing-lever P by the depression of the key-levers n n a causes the rod Q to. depress the arm t, and thereby def prive the before-described clutch of its hold on the hub 70" and limit the movement of the shaft k and pinion 19, attached to said shaft, and inasmuch as the movement of the spacing-lever is varied according to the spacing required for different-sized letters or characters to be printed, as hereinbefore described, the movement of the aforesaid shaft and pinion is correspondingly varied and the feed regulated accordingly.

In order to allow the described feed mechanism to be thrown out of gear when desired to return the carriage O to its starting-point, I fulcrum on the carriage a manipulative lever R, which is provided with a finger R, extending under the weighted lever 0, so that by tilt-ing the lever B the weighted lever is lifted, and thus the gripping-lever s is deprived of its hold on the hub 70', hereinbefore described.

The lever R is formed with a downward extension R", and to the frame or base A at the point where the travel of the carriage is designed to be stopped is attached a tripper S, of the form of an inclined spring-plate, with which the lever-extension R comes in contact, and is thereby moved so as to cause the lever R to lift the weighted lever O, and

thereby trip or stop the feed mechanism.

To prevent the carriage from slipping too freely on its tracks, I fulcrum on the end of the oscillatory arm E, directly over the track D, a brake-lever T, which is provided at its lower end with a brake-shoe T, by which it bears on the track D. The pressure of the brake-shoe is regulated by set-screws 13 13, connected to the brake-lever above and below its fulcrum and bearing on the arm E.

Back of the platen B, and parallel therewith, is a rubber-faced roller U, pivoted to the sides of the frame or base A. Said roller serves to shift the paper upon the platen from line to line to be printed, and is operated by means of a key-lever U, pivoted to the side of the frame A, and having connected to it a pawl 11, which engages a ratchet-wheel Q), attached to the shaft of the roller U. Upon the said roller, throughout the length thereof, rests with one of its longitudinal edges a plate V, which is hinged at the opposite edge to the frame A. The paper to be imprinted passes between the roller U and plate V, and is moved toward the platen by the said roller when turned on its pivots. From the plate V rise standards to w, to which are hinged suitable brackets 2 2, which are adapted to oscillate at right angles to the platen, and are formed with arms, onto which are slipped metallic shoes 4 4, having perforated flexible arms 4 4, through which the arms of the which the ink-ribbon passes.

brackets pass. One of the shanks of each shoe is formed with an offset 4", which engages an angular fixed collar 3 on the bracketarm, and thus the shoe is prevented from turning from its requisite position. Between the arms of each shoe is a spool 5, journaled on the bracket-arm, and by means of a clampingnut 6 on the end of the bracketarm pressing against the out-er flexible arm of the shoe causes the spool to be subjected to the necessary pre sure and friction between the two flexible arms to impart the requisite tension to the ink-ribbon 15, which is wound on the two spools 5 5, and is carried over the platen and parallel therewith by the shoes 4 4;,through The described oscillatory brackets 2 2 are connected with each other by a rod 16, and they swing automatically toward the platen by gravity of said brackets. Detents 17 are attached to the standards to w in such positions as to be encountered by the rod 16 and arrest the movement of the brackets, so as to bring the inkribbon directly over the platen. To the oscillatory arm E is attached a hook 18, which engages the rod 16 during the rising of the said arm from the platen, and thus automatically carries the ink-ribbon away from the platen after each stroke of the printingplunger. This arrangement allows the operator to observe each letter or character immediately after it is imprinted upon the pa per. The standards to w, attached to the plate V, as aforesaid, serve as levers by which the operator can raise together the rear edge of said plate and ink-ribbon for the purpose of inserting the paper.

19 designates a stop, which maybe attached either to the standard w or to the frame A at the side toward which the carriage travels in the operation of the machine. A pendent rod 20 is firmly secured to the oscillatory arm E and is in such a position and of such length as to cause it to strike the aforesaid stop and prevent the said arm from descending sufficiently to allow the printing-plunger to strike the paper lying upon the platen. The purpose of said stop is to arrest the printing process when the carriage is stopped at the end of the printed line.
