SPECIFICATION forming part of Letters Patent No. 487,897, dated December 13, 1892.

Application filed September 5, 1891- Serial No. 404,915. (No model.) 7

To all whom it may concern.-

Be it known that 1, JAMES E. WILSON, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to the class of typewriters in which the type are carried by a rotating wheel or disk and are brought into contact with the surface to be printed upon by a forward or downward movement of the wheel.

The invention has for its object to provide a type-writing machine that shall be simple in construction, accurate and effective in operation, and cheap to manufacture and which shall not only be useful as an educational device for children, but shall be capable of practical use by older people for business and professional purposes.

The invention consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein Figure'l is afront elevation of my improved type-writer. Fig. 2 is an end elevation thereof. Fig. 3 is a front elevation of the same, the type-wheel being removed, showing the bell in position. Fig. 4 is an end elevation thereof, partly in section, showing both the type-wheel and bell in position. Fig. 5 is a plan view, the typewheel being removed. Fig. 6 is a partly-sectional end view looking from the right in Fig. 5. Fig. 7 is an enlarged detail sectional view of the type-wheelcarrying head. Fig. 8 is a partly-sectional rear view of the spacing mechanism in the normal position, and Fig. 9 is a similar view showing the second position.

In the accompanying drawings, the letter A indicates the base of my machine, upon which the operative parts are to be carried. The paper to be printed on is placed upon said base and is held in position by a bar a, shown pivoted at one end to the base A at b and at its free end passing under a hook d, that holds it upon the paper. The base A constitutes a platen for the paper to be printed upon.

In order to permit proper alignment of the paper upon the base or platen A,I place upon the latter a series of lines e, running longitudinally, and another series of lines f, running laterally or at right angles to the lines e, as shown in Fig. 5. By this means the paper can be properly placed upon the base or platen A for printing upon by causing its edges to coincide with the lines 6 f; also, for adjusting the paper to a new line its proper position will be found by the use of the lines ef. The lines ef may be stamped upon the base or platen A or be printed upon paper or the like and pasted upon the base A or otherwise suitably attached. By this means a very cheap arrangement for aligning the paper to be printed on is effected.

Upon the base A are standards 9, that support a rack-bar B. Upon the rack B is mounted a sliding frame or lever D, having a tubelike part h, through which the bar B passes, whereby the frame D is supported and guided on the rack-bar B. The frame D extends forwardly over the base or platen A, and through an aperture 6 in said frame passes a rod E, that is supported by the standards 9 and extends parallel with the rack-bar B. The slot z'is large enough to permit an up-and-down or rocking movement of the frame D over or upon the rod E around the rack-bar B as a fulcrum. (See Fig. 6.)

To the outer or forward part of the frame D is pivoted a lever F, that extends rearwardly toward the rack-bar B and parallel with and preferably close to the frame D. The lever F has a substantially horizontal or longitudinal slot j, through which the rod E passes. By'means of a screw Z, carried by the frame D and passing through a slot m in the lever F, the latter is guided on the frame D and lateral movement of said lever is prevented. On the rearward or free end of the lever F is a projection or finger F that is adapted to enter between the teeth of the rack B to prevent movement of the frame D thereon. (See Fig. 8.) A spring G connects the The lever F IOO at its free end pivotally carries a pawl or lever H, having a toe n, that is adapted to engage the teeth of the rack B. (See Figs. 8 and 9.) In their normal positions the finger F and toe n are in their respective notches of the rack-bar B, Fig. 8; but when the frame D is depressed the lever F (working on the rod E as a fulcrum) is lifted at its free end, whereby the pawl H is lifted, and thereby its toe n advances one tooth on the rack (See Fig. 9.) When the frame D next rises, the lever F descends, carrying down with it the pawl H, which by engaging a tooth of the rack B causes the frame D to advance the space of one tooth. This will occur each time the frameD is depressed and raised,and thereby the advance or feeding of the frame is effected step by step. To the pawl H is also connected an arm 1-1 by which the pawl may be operated.

To leave a space between the words, the type-carrier is turned until the part having no type is broughtin line with the paper, whereupon as the carrier is depressed the pawl will be lifted to move the frame the space of one tooth on the rack-bar, as before described, but no impression on the paper will be made. The pawl H also carries a cam-like projection H adapted to engage the frame D, so that when the arm H is raised the cam H will be pressed against the frame D, the toe n and finger F will be lifted out of the rack B, and

thereby the frame D will be free to be shifted along the rack-bar B.

The frame D at its outer part carries a typewheel I, having a thumb-piece 1 by which it can be rotated. The type-wheelI is mounted on a suitable shaft J on the frame D, and I prefer to give the type-wheel I a slight lateral or oscillating movement on the frame D. For this purpose I connect the shaft J pivotally with the frame D, and prefer to connect the shaft J with a head J that is forked at 0 on its inner end to straddle the frame D, a pivot-pin 19 passing through that part of the head J and through the frame D. (See Fig. 7.) Only a slight amount of motion is allowed the head J on its pivot p.

Between the head J and frame D is interposed a spring q', shown placed in a recess 0 in the frame D and bearing at one end against the frame D and at its other end against the head J (see Fig. 7,) the tendency of the spring q being to hold the head J and shaft J up.

On the inner side of the type-wheel I is a series of teeth L, corresponding in position and in number to the type upon the periphery of the type-wheel I.

On the lower part of the frame D is a tongue or projection M, that is adapted to enter between the teeth L when the type-wheel is oscillated laterally to lock thelatter in position to prevent rotation during the act of printing.

On the face of the type-wheel I is an index, on which are arranged the letters and characters, &c., corresponding to the type on the periphery of the wheel I. (See Fig. 1.)

N is a pointer carried by the frame D and extending over the type-wheel I in line with the characters on the face of the type-wheel, so that to produce an impression of the type the desired character on the index or on the face of the type-wheel is brought opposite the poipter N, which places the corresponding type in line with the platen, and the frame D is depressed to produce an impression.

To ink the type, I secure to the frame D- say at its lower partan inking-pad O, which is normallyout of line withthe type, as inFig. 2. The pad 0 is supported by spring-arms s, that are connected to the frame D, as shown, so that when the type-wheel I is depressed the type will come in contact with the pad and the type to print will be permitted to pass through the aperture 0 in the pad 0. (See Figs. 2 and 5.)

Although my type-writer may be used without a bell, for some styles I prefer to use a bell, and for this purpose I place upon the frame D a standard 25, upon which a bell P is mounted. (See Fig. 4.) Q is its clapper, that is carried by a bell-crank lever B, pivoted on the frame D and acted on to strike the bell bya spring a. The bell-crank leverRis bent across the frame D and then downwardly on the opposite side, (see Fig. 6,) forminga downward projection o. This projection '11 is adapted to be engaged by a counterbalanced trigger S, carried by the frame D.

On the rod-E is an arm T, that is adapted. to engage the trigger S to trip the same to release the clapper Q. The arm T is movable along the rod E, and for this purpose it has connected to it an arm T that is adapted to rest in the rack B to prevent spontaneous side movement. When the frame D is depressed, the lever F engages and raises the bell-crank lever B to draw the clapper away from the bell P, and at the same time the projection o engages the trigger S, which holds the clapper set to strike. "When the frame D has moved along the rack-bar B the required distance, the trigger S will encounter the arm '1, and thereby the projeotiono willbe tripped, thus permitting the clapper to strike thebell.

My type-writer operates as follows: The

paper to be printed upon is first placed upon the base or platen A and straightened according to the lines ef. The type-wheel I is then turned to bring the desired letters of the index opposite the pointer N, which causes the corresponding type to pass in line with the opening 0 in the pad 0. The type-wheel I is then depressed and rocks 011 its pivot 10 until the teeth L engage the projection M to pre vent rotation of the type-wheel. The frame ITS D is now pressed down until the type passes through the opening 0 and reaches the paper to make an impression, the spring-pad O permitting the type to pass through. As the frame D is thus depressed it carries the outer end of the lever F down, which fulcrums on the rod E, and thereby its inner end, carrying the pawl H, rises. As it thus rises, its finger P is lifted out of the rack B and the toe n of the pawl H is moved along one notch. When the frame next rises under the influence of the spring G, acting on the lever F, as stated, the inner end of the lever F descends, causing the pawl H to push the frame D along the rack B the distance of one tooth, whereupon the finger F enters between two teeth on the rack B to hold the frame D from movement. Each time the frame D is rocked the same motions occur to feed the frame D along the base A step by step to space apart the letters. To make a space between words, the arm II of the pawl H is raised, which causes the toe n on said pawl to move the frame D one space.

The manner of ringing the bell, having been already stated, need not be further described here.

Having now described my invention, what I claim is 1. In a type-writing machine, the combination of a rack-bar, a lever or frame pivoted on said bar, a .type-carrier pivotally carried by said frame, said frame being adapted to travel across the base or platen to space apart letters, a lever pivotally connected with said frame, an abutment to actuate the lever when the frame is depressed, and means connected with said lever for moving the frame step by step.
