TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 481,855, dated August 30, 1892.

4 Application filed May 15, 1891. Serial No. 392,818. (No model.)

To all whom it may concern:

Be it known that I, ANALDO M. ENGLISH, of the city, county, and State of New York, have invented a new and Improved Type- Writing Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved type-writer simple and economical in construction and effective in operation, the invention being distinguished by a novel and reliable feed mechanism for Word-spacing, a novel line-spacing attachment, and improved details, all as hereinafter particularly described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters'of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a type-Writer embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a front elevation showing the feed devices in the normal position. Fig. 4 is a front elevation with the printing-key depressed and the feed devices correspondingly moved. Fig. 4 is a detail view for the better illustration of the feed or Wordspacing devices. Fig. 5 is a plan vieW of a portion of the type-writer on a larger scale. Fig. 6 is a like view with the printing-disk and index-wheel removed. Fig. 7 is avertical section through the printing-disk and index- Wheel on the line 7 7, Fig. 5. Fig. 8 is an inverted plan View of a portion of the printingdisk and index-wheel removed from theirinclosing case. Fig. 9 is a broken side view,on an enlarged scale, of the spacing mechanism, the rack thereof being omitted. Fig. l0 is a plan View thereof, and Fig. 11 is an end view thereof.

In constructing atype-writerin accordance with myinvention I provide a suitable table, base, or bed A, and on one side thereof I form a way for the carriage. Such way in the present instance consists of a plate B, ranging longitudinally of the table A and having at one edge a vertical flange B', having rackteeth b at its upper edge for engaging the feed devices. At the base of ange B', the same overhangs the body of the plate B to form a groove b', Fig. 2, which is parallel with a groove b2, formed by bending over the opposite side of the said plate. The grooves b b2 form a guide for the carriage O, upon which all the operative parts of the printing and carriage-feeding devices are mounted.

A case or shell D, comprising a bottom d and vertical flange d', is secured to the carriage C at the inner side thereof, and in such case is mounted the printing-disk E and index-wheel F, such disk and wheel being securedat their centers to a sleeve E', which is held centrally in the case D by a screw E2 or its equivalent, said screw taking at its lower end in the aperture d2, formed in the bottom of the shell D, the arrangement being such vthat the disk and wheel are pivoted for movement in the horizontal plane, and as the index-wheel is rotated in either direction the printing-disk will move in unison therewith.

The index-Wheel F is provided with a series of radial ngers f, preferably spring-fingers, on which characters f are produced corresponding to the characters e on the under side of the printing-disk E. There is further formed on each of the iingers f a projection f2, to be engaged by the finger of the operator in rotating the disk. The index-wheel is rotated to bring the fingerf bearing the desircd character into alignment with the notch d3, Fig. 3, formed in the upper edge of the engage or be engaged by the shell D or other relatively-fixed part of the machine; also, the characters f of the index-Wheel may be arranged otherwise than on the spring-fingers.

The type-impressing device G depends from the impression-frame G', which is preferably of wire and lies, mainly, within the shell D, beneath the index-Wheel F, and has a loop g', which extends outward through the shell and carries an operating-key G2,which I term the printing-key, the ends of the said frame being suitably pivoted, so that the frame may have vertical movement. The pivotal con- IOO nection in the arrangement shown is effected through the medium of the inbent ends ZL of the frame II, which I term the spacing frame, said inbent ends extending through the sides of the shell D. From the pivot ends ZL the frame I-I, which is also preferably of wire, ranges at each side of the shell D and is formed into a bar 7i', which ranges transversely beneath the printing-key G2, so that the spacingframe may be acted on by the said key in the downward movement ot' the latter in printing.

To the cross-bar ZL of the frame II is pivoted the rear end of a feeding-lever I, which is formed with a long sleeve or bearing d', that surrounds the said cross-bar, in order that the lever may be steadied. The feed-lever I eX- tends downwardly and forwardly, and at its lower end is secured or formed a laterallyprojecting stud i', which in the movements of said lever rides on the short run or ledge j, that is formed on a iixed part of the carriage. In the arrangement shown the ledge j is formed by the overhanging upper end of the vertical iiange J, which is formed on a plate J, secured to the carriage; but the arrangement may be varied in practice.

The stud i of the feeding -lever passes .through the inclined slot 7c, formed in the rear` end of the locking-plate K, and in the forward end of the said plate asecond slot Zo is produced, the bottom wall or edge of the lat-` ter slot at its rear end being'higher than the forward end,-as indicated by the letter 7a2. Further, at the extreme forward end of plate K is formed an integral pawl k3, which engages the teeth of the rack Z) and is inclined to readily slip forward over the teeth when being disengaged from the latter. Into the slot Za projects the spring-detent Z, the shank L of which is secured to the carriage C. Normally both the pawl 7c3 and detent Z engage the teeth b. A spiral spring M is secured to the rear end of the carriage C and to the stud Il of feed-lever I.

In operation, the desired character having been brought into position by turning the index -wheeL the printing key G2 is depressed, which depresses the spacingframe H, and in the downward movement of thelatter the front end of the feed-lever I is moved forward. As the feed-lever thus moves forward its stud Z bears against the forward wall of the inclined slot k of locking-plate K, tilting said plate, disengaging its pawl 7a3 from the rack, and moving the said plate forward sufciently for its pawl to engage a tooth in advance. During this movement the higher part 7a2 ot' slot Zt will have been brought beneath the detentZ, and the spring M will have been distended, as the detent Z has in the meantime held the carriage from moving forward. IVhen, now, the pressure on the key Gf2 is relieved by the operator removing his or her finger therefrom, the spring M contracts and draws the stud i backward within the limits of the slot Zt", thus forcing the spacing-frame H and frame G', with its type-impressing device G, upward to their normal positions. Further, the stud 'L' in its initial rearward movement will bear against the rear wall of the inclined slot 7c and will tilt the locking-plate K upward, with the pawl 7c3 as a fulcrum, which actionwill cause the wall 7a2 of slot 7a to lift the detent Z out of engagement with the rack Z), and when the said detent is disengaged the carriage, and consequently the detent Z, will be moved forward by spring M the distance of one tooth.

In order to return the carriage when it reaches the limit of its forward movement, I have provided the 1ifting-bar N,Which is also pivoted on the stud t' and provided with a nger-piece fn, that it may be tilted on its pivot, said finger-piece having a depending lug or fiange fn', bearing at its lower end on the stud t', for steadyin g the bar N in its rocking movements. This lifting-bar extends beneath the detent Z, and when tilted it will lift said detent, and with it the plate K and its pawl 7c3, which will permit the carriage and its appurtenances to be moved backward for begining anotherline.V The movements of the feed and spacing devices just described will be best understood from Figs. 4a, 9, 10, and l1.

It will be apparent that the spacing-frame Il may be depressed independently of the key G2 and frame G', and the gravityalone of the latter will not be suliicient to cause an impression.

The paper I) is shifted by hand for linespacing. It is slipped into a paper-holder O, which consists of an elongated clip formed with a vertical bend o and a horizontal bend or loop o. The clip is slipped over one edge of the paper, and its vertical member 0 is entered in a guide f groove Q, Figs. 3 and 4, formed transversely in the base or table A. Along said holder notches o2 are `produced at regular intervals, and a spring or click `R, secured to the table A, clicks into the successive notches and retains the paper and its holder in the adjusted position. Alongitudinal strip o3, of metal, is fitted in the vertical bend o of the clip, and on the lower side of such strip o3 beveled projections o4are formed, which project through slots formed in the bot tom of the vertical member o. After the clip has been placed on the paper the strip o3 is moved longitudinally in the direction of the arrow, Fig. 2, which causes the strip to be moved vertically by its beveled projections o4 striking the walls of the slots through which they project, and the paper is thus clamped against the horizontal member o. A movement oi the clamping-strip o3 in the opposite direction releases the paper.

The inkin g of the printing-disk E is effected byinking-pads S, arranged at each side of the opening CZ4 in the bottom of the shell D. As the printing-disk is depressed in the operation of printing that portion of it at each side of the opening Z4 will be pressed onto the inking-pads. The vertical flange (Z of the shell IOO IIO

is cut away adjacentv to the pads, as aty d5, to give access to the latter in supplying ink thereto.

The construct-ion shown may be varied in practice Within the limits of the claims hereinafter made, as it will be ,apparent to those skilled in the art that the details in the exact form shown, While illustrating the invention and its capabilities, are not necessarily present as a part of the invention.

Having thus described myV invention, I claim as new and desire to secure by Letters Patentl.
