TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 478,147, dated July 5, 1892.'

Application filed January 21,1892. Serial No. 418,784. (No model.)

To all whom it may concern.-

Be it known that L'GEORGE B. WVEBB, 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 ribbon movements of type-writing machines, and has for its main object to provide a desirable and efficient construction whereby the ribbon may be moved both lengthwise and widthwise; and it consists in the various features of construction and combination of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a top plan view, partly in section, of so much of a type-writing machine as is necessary to illustrate my improvements, the top plate of the machine being shown in dotted lines. Fig. 2 is a vertical section taken at the line as x of Fig. 3. Fig. 3 is a vertical section taken at the line g y of Fig. 2. Fig. tis a perspective view of the vibratory frame or casting with the spool shaft and ribbon-carrier support added. Fig. 5 is a detail View showing the mode of mounting of the ribbon-spool. Fig. 6 is a plan of the heart orgrooved cam.

In the several views the same part will be found designated by the same numeral of reference.

1 represents the top plate, and 2 thetype ring or basket, around which the type bars or levers (not shown) are hung or pivoted in the usual manner. Depending from the top plate are hangers 3, which support at the rear of the machine'a long shaft 4,which is provided with a bevel-gear 5, which meshes with a similar gear 6 upon a shaft or arbor, on which is oscillated a spring-drum 7 in the manner of the well-known Remington machine. To this spring drum or wheel is attached one end of a band or belt 8, the other end of which is connected to some part of the paper-carriage, (represented in the drawings by 9.) During the travel of the paper-carriage to the left the gear-weeel 6 drives the gear-wheel 5 and turns the shaft 4: in the direction of the arrow thereat; but during the travel of the carriage to the right for the commencement of a new line the bevel-wheel 6 and consequently the shaft Aremain at rest, the spring-drum 7 turning only. Thus the shaft 4 turns always in one directionnamely, in that indicated by the arrow at Fig. 1. At each end of said shaft 4 is a double tappet or wiper-cam 10, while near each end of said shaft is a grooved or heart-shaped cam 11. The first-mentioned 6o cams are employed to efiect a lengthwise movement of the ribbon, while the last-nan1ed cams are used to effect a transverse or widthwise movement'of the ribbon.

12 represents as an entirety a' vibratory frame or casting comprising a vertical support or member 13, a horizontally-arranged arm or member 14, and a vertical plate-like member 15. There is one of these-frames or castings pivoted at each side of the machine. The free end of the arm 14 is formed with-a; vertical bearing 16, which surrounds a pin or pivot 17, depending from the top plate 1 and held by a screw 18. The lower end of the bearing 16 rests upon the head of ascrew 19, which takes into a threaded hole in the end of the pin 17, and thus the frame or casting 12 is pivoted and supported.

The vertical plate-like portion 15 is formed with a tubular portion or bearing 20 in line with a hole orperforation at the lower end of the vertical member 13 of the casting, and through said tubular portion and perforation is passed a ribbon-spool shaft 21. Upon said shaft is slipped a ribbon-spool 22, which is cut away at 23 and provided with a spring 24, having a curved or hook-shaped end, which fits into an annular groove 25, formed in said shaft, and presses with sufficient force to enable said spool to turn with said shaft when 0 the latter is positively rotated. This construction also admits of the spool being rotated independently by hand when it maybe desired to thus move the ribbon lengthwise and also enables the spool to be readily detached from the shaft when it may be necessary, while at the same time the construction is such that the spool is prevented from moving endwise upon its shaft accidentally. On the opposite end of spool-shaft 21, nearer the 100 main shaft 4, is secured a ratchet-wheel 26, which is adapted to be turned step by step and intermittently rotate said shaft and its spoolby means of a driving-pawl 27, pivoted by a screw-pin 28 upon a lever 29, which is pivoted at 30 in the plate-like member 15 of the vibratory frame and is bent or cranked, as seen at Fig. The driving-pawl is provided with a heel 31, arranged between two pins 32 on said lever to limit its vibration, and a fiat spring 33 is connected at one end to the lever and at the other end to the hub of the driving-pawl in a manner such as to keep the driving end of the pawl normally in position to turn its ratchet-wheel when said pawl is in use. Below the pivot of the lever 29 is pivoted a detent 34, provided with a weight 35 to insure engagement of said detent with its ratchet-wheel when in operation. Formed integral with said detent is an upwardly-projected linger 36, adapted to be operated upon by a lug 37 on the lever 29 to disengage said detent when said lever is vibrated to throw its driving-pawl out of operative relation to its ratchet-wheel, as illustaated at the lefthand side of Fig. 2.

At the lower end of the lever 29 is connected one end of a spiral spring38, the other end of which is connected to the horizontal member 14 of the vibratory frame. Projecting to ward the right from the lever 29 and formed integral therewith is an arm 39, which is provided with a rearward projection 40, that extends under the wiper wheel or cam 10, so as to be acted upon thereby.

Referring to the right-hand side of Figs. 1, 2, and 3, it will be observed that the lever 29 is arranged for action and that the drivingpawl 27 is in engagement with its ratchetwheel. At this time the spiral spring 38 is acting against the cam 10, and hence holding the projection 40 in contact with said cam. Now as the cam revolves in the direction of the arrow it gradually forces down the pro jection 40 and vibrates the lever 29 against the tension of the coiled spring and operates to pull the driving end of the pawl back the distance of one notch of the ratchet-wheel, the cam rotating in a plane at right angles to the plane of vibration of the pawl-carrying lever. As soon as thishas been accomplished the low or cut-away part of the cam arrives at the said projection, which then immediately flies toward the center of the cam under the influence of the spring 38, and simultaneously thelever 29 is vibrated by the force of said spring and the driving-pawl is caused to push the ratchet-wheel and spool the distance of one tooth, and hence wind up aportion of the ribbon at upon the right-hand spool.

As will be observed by referring more particularly to Fig. 2 of the drawings, the means for winding the ribbon upon the left-hand spool are at this time thrown out of use. This is accomplished by pushing down upon the outer extremity of the arm 39 of the lever29, which is extended to form afinger-piece, so as to rock the lever 20, raise the driving-pawl out of engagement with its ratchet-wheel, and simultaneously by means of the linger 36 and lug 37 cast off the detent, thus freeing the lefthand ribbon-spool from its rotating means and permitting it to revolve and pay off in accordance with the pull exerted by the righthand ribbon-spool through its actuating devices.

It will be observed at the left-hand side of Fig. 2 that when the arm 39 is depressed to disengage the pawl and detent the spiral spring is so shifted that its pull or tension is exerted on the opposite side of the pivot of the lever, and hence the spring operates to hold the lever and its accessories in their inoperative or unusual position.

\Vhen the ribbon may have been wound step by step onto the right-hand spool and it may be desired to reverse its longitudinal direction of movement, the devices at the righthand side of the machine are thrown out of engagement by depressing the arm 39, as above described, and the devices at thelefthand side of the machine are thrown into 01)- erative relation to the ratchet-wheel and spool by simply raising the arm 39 of the lever. Thereafter the cam 10 at the left-hand side of the machine will operate through the means described to intermittently rotate the left-hand spool positively and cause it to wind upon itself the ribbon on the spool on the opposite side of the machine.

I shall nowdeseribe the means employed for moving the ribbon widthwise or transversely, the devices for doing this work, like those for moving the ribbon lengthwise, being the same at each side of the machine. Secured in a hearing at the upper end of the vertical part 13 of the vibratory frame is a l1orizontally-arranged pin or arm 42, upon which is mounted the tubular end 43 of a ribboircarrier 44, which is provided at its inner end with a transverse loop or guide 45 and between its ends with lateral arms 46,the said loops and arms serving to support and guide the ribbon. On the under side of the ribbon-carrier 44: are riveted two spring-plates 47, which at their free ends rest normally in depressions 48 on the upper and lower sides of the pin or arm 42. The ribbon-carrier is adapted to be turned up to a vertical position to enable the ribbon to be lifted to consider able height, so that the operator may conveniently clean the type when necessary without interference by the ribbon and liability of soiling his hands. When the ribbon-carrier is turned up to a vertical position, the springplates 47 slide around on the curved or cylindrical portions of the arm 42 and are expanded slightly, and by their pressure serve to hold the ribbon-carrier in its upright position. Extending rearwardly from the vertical plate-like portion 15 of the vibratory frame is a pin or projection 49, which is operated upon by the grooved or heart-shaped cam 11, and a vibratory motion thus given the frame or casting 12 and the various devices carried thereby. The cams 11 are arranged upon the shaft 4, so that the vibratory frames are moved first in one direction and then returned during a complete revolution of the shaft, and hence the ribbon-carriers and the ribbon are moved laterallyin one direction during one-half of the revolution of the shaft and in the opposite direction during the remainder of the revolution of the shaft. In the positions of the parts shown at'Fig. 1 the earns 11 are acting upon the pins to move them towardeach other or inwardly, thus rocking the vibratory frames about their pivots l7 and moving the ribboncarriers toward the front of the machine, as represented by the dotted lines. When the portions50 of the cams arrive at the pins 49, the forward vibration of the ribbon-carriers has been completed, and as the cams continue to revolve their opposite sides press upon opposite sides of the pins and operate to force them outwardly or away from each other, thus rocking the vibratory frames in the reverse direction and causing the ribbon-carriers and ribbon to move rearwardly. The portions 50 of the cams 11 are preferably flattened for the purpose of delaying for a moment the reverse rocking motion of the vibratory frame in order to allow at this time the devices for moving the ribbon longitudinally to come into action. The fiat portions of, the cams 11 and the cut-aways of the cams 10 are relatively so arranged that the instant the flat portions of the cams arrive at the pins 49 at each halfrevolution there is a cessation of widthwise. movement of the ribbon, the projection 40 passes off of the high point of the cam 10, and the spring-actuated driving-lever 29 is moved to cause its pawl to turn the ratchet-wheel and wind up a small portion of the ribbon., By the time this longitudinal movement has been effected the earns 11 have been turned sufliciently to cause the flat portions to pass beyond the pins 49 and at once the reverse widthwise movement of the ribbon begins to take place. By this construction and arrangement thev ribbon is enabled to move laterally while the means for moving it longitudinally are at rest and is enabled to move lengthwise while the means for moving it widthwise are out of action. Thus there is no conflict between the means forv effecting. a widthwise movement of the ribbon and the means for.

movement is changed by the operator.

The ribbon is used widthwise itswhole ex-.

'of the next line the movement of the ribbon widthwise will be continued in the same directionfrom the point where it was stopped bythe previous return of the carriage. Thus the use of the ribbon for its full width is insured, no matter what may be the length of the travel of the carriage or the length of the lines written.
