TYPE-WRITING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 447.790, dated March 3, 1891.

Application tiled July 28,1889.

To all whom, it may concern.-

lie it known-that I, FRANK E. WILDER, of Salem, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in 'lype-Mriters, of which the following is a specification.

The object of my invention is to furnish a simple, inexpensive, light, and reliable typewriting machine that maybe operated as rapidly and in asimilar manner by the keys, and also just as practically, as the more expensive and bulky machines.

Another object of my invention is to furnish such a machine that will write with the paper in a horizontal position and under the eye, so that the writing can be read the most readily without having to previously lift up any mechanism and while the writing is being done.

In the accompanying drawings, forming a part of this specification, Figure 1 illustrates a plan viewof myimproved type-writing machine. Fig. 1" is a back view of thesame. Fig. 2 is a transverse vertical section, taken through the line a: a: of Fig. 1. Fig. 3 is a similar section through the line y y of Fig. 1, but with the paper-carriage and its connecting parts removed. Fig. 4 is an end view of the left-hand end of the paper-carriage and its connecting parts. Fig. 5 represents in detail the mechanism for drawing down the type cylinder or spools. Fig. 6 is a plan of the back portion of thc'machinc, the front portion and keys being broken away and the papcr-carriage, with its connecting parts, removed. Fig.7 isalongitudinalsection through the line 2 z of Fig. 6. Figs. 8 to 12,-inclusive, are details.

SimiE-arletters and numerals represent like parts in all the figures.

A is the frame of the machine, which supports the working mechanism, and B is the longitudinal back bar of said frame forming the rail, upon the upper edge of which the rollers of the paper-carriage are adapted to travel. The upper portion .of the rail B extends outwardly, forming a flange having a longitudinal shoulder a parallel to the top of said rail.

0 is the frame for holding the paper-cylin- Berisl No. 818,216. (No modelJ der, inking-ribbon, &c., and constitutes the traveling paper-carria e. Said carriage suports the ordinary revo ving cylindrical platen l to one journal of which is secured the platen knob or handle I), and to the other jou rnal or opposite end of the platen is secured the rate let 0. The grooved carriage rollers or wheels d d are journaled to the back of the carriage O, and are adapted to ride over the rail B.

lie the front bearing rod or rail of the paper-carriage, which rests upon and is adapted to ride over a roller 2, journaled on the frame A, and 0. lug 3, extending over said rollcrand rail, serves as a guide for the rail. 44 are two lateral pins-projecting from the paper-carriage, one at each end, over which the ribbon 1 passes and is stretched.

A plate E, having projecting ends 6 e, extending downwardly from the same, is removably attached to two lugs or projections f f, extending outwardly from the carriage G.-

The ends e e are bent inward, forming lugs g g, which extend under and against the shoulder a. Said plate E, with its lugs g g, serves as a' guide for the paper-carriage and to keep it firmly in its position on the rail B. The plate E may be adjustably attached to the carriage C by means of screws and slotted holes in said plate.

Extending downwardly from the carriage G are two lugs h h, which form journal-bearings for a rock-shaft F. Two arms 1' '1 are socured to said shaft and extend inwardly from the same, and the rack G is supported longitudinally with the carriage by said arms to which said rack is secured. Anarm H extends upwardly and outwardly from the shaft -F, by which arm the rack is adapted to be lifted. The rack G may either be held down in its normal position by its own weight or a spring may be used for this purpose. The spring line-space lover I to which the pawl or dogj (for operating the platen-ratchet c) is attached, extends outwardly (see Figs. 1, 1*, and 2) and in frontof the arm II, and said arm will bear against the leverl, so that when the latter is pushed down it will carry the arm H with it, and thus raise the rack G.

The ribbon-reelsJ J are hung on journals I00 la 1:, which extend laterally in front of the carriage C, and with the ribbon 1 extending longitudinally over the top of the platen. Coil tension-springs m m may be inserted het-ween the reels J J and adj usting-nuts n n,if so desired. 4n -adjusting-screw 0 extends through the back of the carriage C, with its end abutting against the lower ar'm'b of the lever I, and serves to regulate the play of said arm in ahackward direction and the forward play of the dogj.

"A pinion K, having a ratchet L secured to its back surface, is loosely journaled upon the frame A in such position that when the carriage C is in proper position, with its rollers d d on the rail B, the rack G will engage with said pinion." Then the rack G is lifted by a the arm H out-of engagement with the pinion K, the paper-carriage can readily be slid back and forth. A spring-actuated arm M, pivoted longitudinally to the frame A, has a pivoted dog or pawl g, which engages with the ratchet L, the actuating-spring of said arm tending always to bear the dog q down against said ratchet. The free end of said arm Mis provided wit-ha pin or projection 0",

which is adapted to engage with the rack G when said pin is lifted and to hold said rack firmly until the pin releases it; 7

N is a rod extending longitudinally the entire length of the machine,and which constitutes the fulcra of all of the key levers 0 and I, which are levers of the first class.

Q and R are two longitudinal" bars, each of which is pivotally connected with the rod N by right-angled backwardly-extendi'ng arms s, the bar Q beingjust in the rear of the bar R.

The key-leversO of the forward and lower' row of keys S extend back and'under the bar Q, and the key-levers of the back and upper row of keys '1 extend back only under the bar R, said levers 0 and P bearing against thel under side of the bars Q and R, respective y. r

A bell-crank lever S" is pivoted to the rod N about half-way between its ends, the upper arm of said lever having a backward projection S extending over the bars Q and R, and with downwardly-extending pins or projections bearing on the top of said bars. The lower arm of the lever S" is provided with a lateral lug f, on which the space-key arm U rests, said arm being loosely hung upon the rod N and not extending back of the same. A bell-crank lever V is also pivoted on the arm N and has its upper arm 11. attached to the lever S",its lower arm 1: extending backward and under the arm M. hen the spacekey arm U is depressed, the arm 1; of the lever V will raise the arm M and the dog out of engagement with the ratchet L, and when said arm is released the dog q will fall back, engaging with the next tooth of the ratchet L, and this move the rack K and the paper carriage to the left the space of one letter.

NV is a bar, upon which is secured or cast at rightangles to the same atube or cylinder X, and this bar and cylindcr'are' supported by journal-bearings on either end of said bar on raised supportsy Z near the center of the machine, so that the cylinder X will be transverse to the machine. Two arms 10 10 extend forward from the bar \V, and one of said arms is connected by a link a: to the forward end of a spring bell-crank lever A ;-pivoted to the rod N, the backward and upper arm of said lever A (see Fig. 5) extending over the bars Q and R in a similar manner to the l ver S" and. with similar bea ng points or rejections.

The cylinder X forms a long stationary Bof the type-cylinder C, and when either of the bars Q or R is raised by any of the key- .levers the inner arm of the lever A will be depressed and through the link a: draw down the bearing X and the type-cylinder C onto the ribbon and against the paper and platen. When the key-lever is released, the springlever A will return to its normal ition, and the bearing X and the type-cylinder 0' will he raised'again.

The type is placed or arranged on the periphery of the cylinder 0 in a somewhat ,similar manner to that of the Crandall typewriter, and it is therefore nry to-have mechanism for revolving the cylinder in order that the type corresponding with the key that is struck may be directly over the ribbon. The mechanism as above briefly stated is as follows:

D is a pinion, which fits intoarecess in the bar W. The shaft B of the type-cylinder (3 extends loosely through said pinion, and is keyed to said shaft by a feather fitting into a longitudinal groove a inthe shaft. By this means the shaft B may freely have longitudinal play in the pinion D; but when the latter revolves the shaft B and cylinder 0' will also have to revolve.

E is a vertical segmental gear fixed to.the rocking horizontal shaft b and engaging with the pinion D.

laterally from the same. A similar segmental gear G engages with the gear F, and is se cured to a rock-shaft H, extending the length of the machine.

I I I are downwardly-extending arms keyed to tli rock-shaft II and passing be tween the'key-l'evers O and P. The lower end of each arm I is provided with lateral lugs extending each side of the arm or a pin a, passing through said arm. Each key-lever 0 and P has a cam-shaped slot d, with curved walls extending, up from the lower edge of said lever, and the lever when depressed brings one of the walls or edges of the cam-shaped slot into contact with one of the pins 6 on the arm 1 bearing against said pin, so as to rock the arm 1, shaft H, and racks G and F, and thus rotating the pinion D and the type-cylinder C. The arms bearing for supporting the shaft or spindle I are keyed at such an angle on the shaft Ii in relation to the type on the cylinder 0 that when a particular key is depressed it will immediately bring its corresponding type on the c linder 0' directly over the inking-ribbon. t will be understood that the type-cylinder C does not return to a central or normal position after a key-lever is deressed, but remains in the position said keyever left it, and the cam-slots d are of such shape and the arms I set-at such an angle thereto that any key will bring the cylinder to its proper position, no matter in what position the preceding key had.left it.

I will now proceed to describe the mechanism for moving the type-cylinder 0 forward and backward in order that a type from any row on said cylinder may be brought into position over the inking-ribbon.

J is a vertical plate, having two horizontal and longitudinal slots e f, (see Fig. 3, and g h are headed screws or pins extending through said slots and into laterallugs of the frame A, thus allowing the plate J to have longitudinal play.

The shaftvB of the cylinder 0 has keyed upon it a pinion t" for a par ose hereinafter to be described,andj' is a oose sleeve oncircling the shaft B and held from longitudinal play on said shaft by means of a short collark and a binding-screw passing through the same and bearing against said shaft. The sleeve j is connected by a link I to a vertical plate or bar K, which is secured to the plate J. A backwardly-projecting bar m extends from the plate K, and has a narrow upper edge, which is adapted to engage with the teeth of the pinion i, when thelatter and the type-cylinder G are depressed, thus looking an d type-cylinder and holding it firmly while the type is striking the ribbon and paper. A lug having a vertical slot 01- projects upwardfrom the front of the lug 3, and said slot serves as a guide for the bar m. (See Fig. 8.) L is a spring-lever which is piv oted to the top of the f ame A and with the outer end of its longer arm bearing against a shoulder 0' on the top edge ofthe plate J.

M (see Figs. 1 and 2) is an L-shaped lever loosely journalcd on the rod N near its lefthand end, the short upper arm of said lever bearing against the back edge of the short arm of the lever L and the front end of the lever M extending to the front of the machine near the keys, and'also provided with a key.

the lover M, and has a lateral lug 1) extending from its top edge and resting on the top edge of said lever M, so that when the arm 1\" is depressed the lever M will also be carried down with it. Two shoulders q r in the front of the frame A serve as stops to the downward play of the lever M and arm N, respectively. The arm N extends in front and beyond the lever M and is provided with a key similar to said lcvcr. When the arm N is depressed,

An arm N is also loosely pivoted 0nthe rod N by the side of it. carries the lever M! down far enough, so as to force the type-cylinder C forwardaslight distance through the instrnmentality of the lever L, plates J and K, and link I, and when the lever M is depressed untilit strikes the stop q said lever carries the type-cylinder forward still farther. Said lever M and arm N are so regulated with the parts connecting them with the type-cylinder C that when the arm N is depressed to its fullest extout the capital-letters type on the third and fourth rows from the back end of the cylinder will come over. the inking-ribbon, and when the lever M is depressed to its fullest extentthe figures andpunctuation-markstype on the last two or forward rows of the cylinder will come over the inking-ribbon.

O and P (see Fig. 3) are two bell-crank levers loosely pivoted side by side to the rod N and with their backward,ends s tsecured to the top of the bars Q and B, respectively. The lower forward portions of said levers Q and l are provided with cam-shaped slots to and v similar to those of the keyrlevers, and said slots are adapted to engage with three pins w, extending laterall from thelower portion of the plate J.v T 0 object of these cam-slotted levers OP' is to bring the proper row of characters on the cylinder C (there being two rows for each set of .characters) above the ribbon and the portion of the platen to be struck simply by the depression of the required key. the action being performed from the key to the bar Q or R to the lever O or P ,and'thence tonne of the pins w ,the plates J K, link B, and the type-cylinder C.

Q Q are two levers loosely journaled on the arms w with the rear and shorter arms of said levers extending under and resting against thelower edge of the bar \V. The forward and longer arms of the levers Q Q extend as far as the type-cylinder C, where they are formed into loops, through which the inking-ribbon 1 passes.
