JAMES IIOUIJEIIAN, OF CHICAGO, ILLINOIS.-

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 442,318, dated December 9, 1890. Application filed August 1, 1890- Serial No. 360,616. (No model.)

To all whom, it may concern/.-

l 3e 11; known that I, JAMEs IIOULEHAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illian improved attachment for a type-writing machine for producing the return of the car riage to or toward its initial position, and thereby also actuating the spacing-roller from a key located at or near the key-board, thus to enable the return of the carriage to be accomplished by the operator without to that end requiring attention to be directed from the work and without entailing interruption of the type writing position of the operator,

nor variation in the position, motion, or action of the hands in manipulating the keys.

The object of my improvement is to provide a device for the purpose which shall involve positively-acting mechanism for returning the carriage; and a further object is to pro vide the device as an attachment adaptable to various forms of type-writing machines without thereby impairing or interfering with the operations of the other mechanisms thereof.

To these ends my invention consists in the general construction of my improvement; and it also consists in the details of construction and combinations of parts.

In the accompanying drawings, Figure l is a vertical sectional view in elevation of a type-writing machine provided with my improvement, the section being taken at the line 1 of Fig. 2 and viewed in the direction of the arrow; Fig. 0 a partly-broken view in rear elevation of the same, and Fig. 3 a perspective view of a detail.

To illustrate my improvement, I show it as applied to a particular and well-known form of type-writing machine-the Remingtonand for the sake of convenience I confine the description hereinafter contained to such particular application. I do not, however,

wish to be understood as limiting the appli cation of my improvement to such machine, but intend it for use with any form of typewriting machine to which it may be adapted. A is the frame of the machine, having the key-board Bat its lower forward portion and provided with the keys l3 and spacer-bar B connected, as usual, with the keylevers, from which the type are controlled by well-known means.

0 is the carriage, pivotall y supported on the guide-rod O at the rear of the elevated portion of the frame, and carrying the spacing roller D, provided with the bent hand-lever E for producing the separation or rise of the rack F to unlock or disengage it from the dog I and being further provided with the dog F to engage with the ratchet (1' on the end of the roller D, to turn the latter for spacing, with the manipulation of the hand-lever to return the carriage by hand.

G is the coiled-spring device supported toward the rear of the frame below the carriage at the side toward which the carriage travels from its initial position, and G is the band connecting the spring with the carriage to set the spring by the return of the carriage toward its initial position, thus to elfectautomatically the movement thereof in the opposite direction when its rack F is released from the dog F by the manipulation of the keys. These and other features which do not require mention to enable my improvement to be comprehended will be recognized as forming the wellknown type-writin g machine referred to.

Following is the description in detail of the construction forming my improved attachment.

To the support 1 of the rack F (or other part of the carriage) secured to extend parallel with it another rack II. On the rear side of the upper part of the frame A is pivoted a lever Lfulcrumed between its extremities to the frame and carrying at one end a pinion I, controlled by a dog 1' and adapted to be brought into and out of engagement with the teeth of the rack ll above itby raising and lowering the lever from its opposite end. This last-named end of the lever I has pivoted to it one end of a link g, which is bent to bring it toward its opposite end parallel with the rear surface of the corner-post p of the frame A. On the rear surface of the post p is secured a bearing-plate K, having 1 0, respectively, near its opposite guides 0 and ends for the link q, and between the said guides a lug 'n'is provided on the bearingplate nearits outeredge, the lug being adj ustable up and down to a limited extent and held by a set-screw n in its slot n L is a species of dog or catch, preferably of the anchor shape illustrated, being provided with the cross-piece on near its upper end, near one extremity of which it is pivotally connected eccentrically with the link g at an ear q, extending'laterally from the link, and at its lower end with a head m, rounded on its under side, recessesl and Z being thus provided between the said cross-piece and head, respectively, on opposite sides of the catch.

M is a compound lever, the handle-section L of which, forming the key, is fulcrumed on a support or red 7t, near the front of the frame A, and extends thence preferably, as shown, into the key-board at the right-hand side thereof. The other section k of the compound lever M is pivotally connected at its end having a slot m with the inner end of the section It, and is fulcrumed between its extremities, at 00, to a bearing 1), secured to the inner side of the post p. The rear end of the section A of the lever M is controlled, to tend normally to rise, by a spring 3, and extends through the recess 1 of the catch L, being con-- fined therein by the portions of the crosspiece m and head on, which project beyond the inner side of the post p and inner edge of the bearing-plate K therein.

At the upper and lower ends of the inner edge of the plate K are socket-bearings 2' for a vertical rod 71 N is a lazy-tongs, pivotally secured at the upper extremity of its end bar 9 to the rod it near its upper end, and at the lower extremity of its end bar g to a sliding collarf on the rod 72 and from which extends a stud f be low and into the path of the rear-projecting end of the section k of the lever M. The opposite end of the lazy-tongs is connected at the junction of its forward end bars g with the slotted end of a rigid link 0, depending from the rack II.

The eccentric or tripping bar C commonly provided on the carriage pivot-rod O for the rear curved end of the hand-lever E to press against to effect raising of the rack F on its pivot-bar C out of engagement with the dog F, is provided with aslotted extension-piece d, and on the curved portion of the lever E, behind its rear extremity, I secure a tongue 0, to depend therefrom, and having a head 0 at its extremity. \Vhen thecarriage is down or in its horizontal position, the tongue 0 projects through the slot in the extension (Z, which is narrower than the head 0', and to raise the carriage from the hand-lever E in the usual manner the slight backward movement of which the carriage is susceptible (and which is also produced, as usual, by depressing the cap key) moves the tongue backward out of the slot in the forward end of the extension (1, whereby it may pass upward beyond the extension, and thus permit the carriage to be raised from the hand-lever on its pivot-rod without obstruction from the head 0. As will thus be seen, the machine may be operated in the usual manner to perform all its functions in the usual way, since my attachment does not. in the least interfere with such operation.

The use of my improvement involves the following operation: Supposing the carriage to occupy its initial operative position, manipulation of the keys in writing causes the spring device G to move the carriage, as usual, step by step to the end of its route, from which it requires to be returned, and by returning which the roller D should be turned to space the paper. All this may be accomplished by a single pressure upon the key portion 7a of the lever M. Such pressure causes the section k of the compound lever to press against and force downward the catch L, pivotally connected at its upper outer corner with the eccentric, extending laterally from the link q, and the lower end or head m in such downward course of the catch L bears against the inner side of the adjustable bearing a and is thereby guided to maintain a vertical position in its downward course until the head m passes the lower end of the lug a, when the continued pressure against it by the section of the compound lever forces it, owing to its eccentrically-pivoted support 00 out of the path of the said section, whereby the latter may then bear against the stud f at the lowerextremity of the lazy-tongs. This much of the movement of the lever M also by the downward course of the link q produced by that of the pivotal catch L raises the free end of the lever I, carrying the pinion I, engages the latter with the teeth of the rack H, and forces that rack upward, thereby also raising the rack F on its pivot-rod C out of engagement with the carriage-controlling deg F, when the carriage is freed to permit it to he returned to its initial position. The raising of the racks ll an d F furthermore lowers the extension (I of the trip C against the head 0 of the tongue 0, causing its bearing force against the head 0 to pull downward the curved end of the handleverE, and thus force the deg F against the ratchet D to turn the spacing-roller D. Obviously, if the lug n be adjusted higher, whereby the catch L will the sooner pass it and be disengaged from the downward pressure against it of the compound lever, the extent of turn of the spacing-roller D will be the less, while conversely, if the spacing is to be greater, the lug a should be adjusted lower for the purpose. Thus, as will be seen, the first effect of pressure against the key 7c of the compound lever M is to turn the spacing-roller D, and obviously this may be produced without entailing return movement of the carriage, which is the result of continued pressure on the key 70, whereby the end k of the operating-lever M is impinged against the stud f, which by lowering the sliding collar contracts or folds the lazy-tongs N, thus by the connection of its arms g with the link 6 pulling the carriage back from any position it has attained by movement under the influence of its motor Gr from its initial position, which last-named movement produces the extension of the lazy-tongs illustrated in Fig. 2. When the carriage has been thus returned, release of the lever M permits the spring 3 to act to return it to its normal position, in reaching which the section 7;? raises the catch Z, and with it the adjacent end of the lever I, whereby the opposite end of the latter, carrying the pinion, is lowered, disengaging the pinion from the rack II.

The purpose of the dog 7', controlling the pinion I, will be readily understood to be that of causing the pinion to lock the carriage against movement by the spring device G when the carriage is raised sufficiently to release its rack F from the dog I and before the lever M has been brought at its section 73 against the stud f.

The means illustrated and described are believed best to answer the purpose of my improvement, though they may be variously modified without thereby departing from my invention, which I consider broadly to include any means operating positively, by pressure on a key k, to actuate the lazy-tongs to pull back the carriage toward its initial position. For example, other means might be provided to perform the functions of the pinion I, which term I therefore intend to include any substitute for the pinion.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

I.
