TYPEWRITER AND THE LIKE.

Application filed August 4, 1926. Serial No. 127,035.

This invention relates to typewriting machines and particularly to means for limiting the travel of the carriage such as for defining the margins, for paragraphing and for tabulating.

The object of the invention is to improve and simplify such limiting means, with which the limits of travel of the carriage may be varied Selectively as required or desired in the normal use of the machine, by simple manipulations of conveniently positioned controlling parts, and which will be compact and relatively inexpensive in construction.

Various other objects and advantages will be apparent from the following description of an embodiment of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

In the accompanying drawing:

Fig. 1 is a rear elevation as it appears during the normal typing operation of the tabulating and carriage control mechanism.

Fig. 2 is an end elevation of the same.

Fig. 3 is an elevation of a part of the same but with the stop carrying bar or bail in a different operative position; and

Fig. 4 is a plan of part of the mechanism for the control of the carriage.

In the illustrated embodiment of the invention, the carriage 1 is mounted for travel transversely of the machine frame or base 2 being guided in its travel by the usual support bar with the interposed ball bean ings 3. A margin rack bar 4 is securedat its ends to arms 5 and (S which depend from and are hinged on studs 7 and 8 of the car riage frame. The arms 5 and 6, with the margin rack bar 4, function as a bail which is capable of swinging movement forwardly and rearwardly of the machine, that is. in a direction transversely or crosswise of the direction of travel of the carriage. The bail is disposed at the rear of the machine, as shown in Fig. 2, and is normally urged forwardly by a coil spring 9 which surrounds one of the studs, such as 8, one end of the spring being interlocked with a portion of the carriage and the other end with the adjacent arm 6 of the bail.; The forward movement of the bail under the action of the spring 9 may be' limited by the engagement with the frame 2 of tongues 10 on the arms 5 and 6 which are bent forwardly for engagement with a portion of the carriage 1.

The various carriage control stops are mounted upon the margin rack 4 for adjustment there along to various extents. For example, a margin lock. and a bell ringer stop 11, one or more tabulator stops 12 and a margin and paragraph stop 13 may be provided upon the bar 4. Upon the base 2 of the machine a fixed margin stop 14; and a fixed tabulating and paragraph stop 15 may be secured in any suitable manner, but at different distances from'the front of the machine. The tabulator and paragraph stop 15 is located further in the rear on the base than the margin stop 14L. hen the margin bar 4 is in its normal or forward position, as limited by the engagement of the tongues 10 with the carriageframe, the depending or pro ecting trip portions of the stops 12 and 13 will travel with the carriage in the same path or plane and forwardly of the corresponding portions of the tabulator and paragraph stop 15.

The depending portions of the tabulator stops will pass idly above the fixed margin stop 14.,but the depending portions of the stop 13 will engage with the fixed margin stop 14 when the carriage is returned to start a line andlimit the return of the carriage. The depending portion of the margin lock and bell ringing stop 11 normally passes in the rear of the fixed margin stop 14 and is provided with an outwardly inclined or oblique car 11 which engages with the fixed stop 15 by which the ear 11 and the margin rack will be swung rearwardly to clear the stop 15. The latter is positioned at such a point on the base that the stop 11 will first lock the key mechanism and determine the'margin limit before its ear 11* strikes the fixed stop 15. When the bail is swung rearwardly the depending portions of the margin line lock stop 11, the tabulator stops 12 and the paragraphing and margin stop 13, will travel in paths which intersect with the fixed tabulator and paragraphing stop 15, and will clear the fixed margin stop 14. This rearward position of the bail is shown in Fig. 3, the normal or forward position being shown in Fig. 2.

'A shaft 16 is rotatably mounted in brackets 17 on thebase 2 so as to extend in a direction parallel to the direction of travel of the carriage. One end of the shaft 16 is bent angularly thereto, as at 18, to form a arm just forwardly of but adjacent to the margin rack bar 4. The other end of the shaft 16 is also bent angularly to form a crank arm 19, which terminates in a crank pin 20. The crank pin 20 is received in a looped end 21 of an upstanding arm 22 of a push rod 23. The rod 23 extends forwardly of the machine and adjacent theusual key board is slidably mounted in a comb or plate 24. This rod 23 may also be slidably supported intermediate of its ends if so desired. An arm 25 is secured by its boss 26 and a screw 27 to the forward end portion ofthe rod 23, and extends upwardly and is provided with a key 28 at its upper end. The arm 25 may also have a forwardly extending pin 29 which is also slidably mounted in the plate or comb 24 in order to prevent rotation of the rod 23, without restriction of its endwise movement. Thus by operation of the key 28 the arm 18 of the shaft 16 will be rocked rearwardly to engage and move the margin rack bar 4 or bail rearwardly.

An operating lever 30 may be hinged intermediate of its ends upon one of the studs, such as 7, which mounts the bail. The upper end of the lever 30 may have a finger engaging flange 31 located adjacent to the upper face of the carriage, so as to be accessible for convenient manual manipulation. The lower end of the lever 30 extends along one of the arms of the bail such as arm 5 and carries a tongue 30 which extends beneath that arm so that when the lever finger piece 31 is shifted forwardly, the bail Will be shifted rearwardly. It will be noted, however, that the bail may'also be shifted rearwardly by the operation of key 28 without moving the lever 30.

The travel of the carriage in a feeding direction is controlled by an escapement device 33 of any suitable or usual construction, which is connected through a. clutch element 34 to a pinion 35 and the latter meshes with a rack 36 carried by the carriage 1. The clutch element 34 is normally urged into a clutched engagement with the pinion by a nelical compression spring 37. arm 38 is mounted for rocking movement upon a shaft or stud 39, and is provided with a lug 40 which engages in an annular groove 41 of the clutch element 34 so that when the arm 38 is rocked in one direction it will shift the clutch element 34 out of clutching engagement with the pinion 35 and thus free the carriage from the control of the escapement device.

A. carriage release lever 42 is pivoted at 43 to one of the end plates of the carriage frame, and one of its arms is provided with a radially elongated slot 44 which receives a pin 45 that projects from an car 46 of a 'toward the front by ones fingers.

In the operation of a typewriter equipped with such carriage controlling mechanism let it be assumed for example, that the carriage is traveling in a feeding direction under the control of the escapement device that is operated by the ty e bars which print upon the platen A (see Fig. 2). As the carriage approaches the end of the line, the depending portions of the margin lock stop 11 will engage with and operate the usual or any suitable line lock mechanism (not shown) which looks the type bars against further printing operation. Just prior to this locking of the type bars however, the stop 11 will operate the usual or any suitable bell ringing mechanism (not shown) in order to warn the operator that the carriage is approaching the end of the line. If the operator does not return the carriage, the line lock mechanism becomes effective. The lock mechanism may be released from the control of the stop 11 in order to type a few more characters by a rearward movement of the bail through the operation of the margin release key 28. The details of the margin lock and release margin mechanism do not, per se, form a part of the present invention, but are described and claimed in the copending application of John H. Barr, Ser. No. 79,913 filed Jan. 8, 1926'.

After the type bars are released for further operation through the rearward shifting of the hail, the operator may continue to write a limited number of spaces. The operator then returns the carriage to starting position in the usual manner if there is to be no indentation or paragraphing, and

this return of the carriage will be limited by the engagement of carriage stop 13 with the fixed margin stop 14. If however, the new line is to be indented or paragra bed the operator in returning the carriage s lifts-the upper end of the lever 30 forwardly and thus shifts the bail rearwardly while the carria e is being returned. During the return of the carriage under such a condition, the depending portion of stop 13 will move in a path different from that reviously traveled and will strike against tlie fixed stop 15 before it reaches the fixed margin stop 14. The re turn of the carriage is thus shortened by the 30 and 42 are then released which restores the carriage to the control of the escapement. The tension on the carriage by its propelling spring, however may hold the stop 12 tightly against the fixed stop 15, and the bail may beheld against return or forward movement by the friction between the engaging stops. To release the carriage the operator may operate the key 28 to shift the bail further rearwardly and the slight forward movement that the carriage then takes will carry the stop 12 somewhat along a face of the stop 15, so that upon release of the A key 28 the carriage will be free to continue in the feeding direction under the control of the escapement device. As soon as the car riage travels a few letter spaces, the stop will clear the fixed stop .15, and the bail will thereupon be moved forwardly into normal position by the spring 9.

If one desires to tabulate at a second point in the same line, the carriage is again released by shifting the levers 30 and 42 forwardly, whereupon the released carriage maybe moved in a feeding direction until the next tabulator stop 12 on the bail engages with the fixed stop 15. The'following operation is similar to that just described in connection with the first tabulator stop. Any number of tabulating stops 12 may be employed, up to the limit of the length of rackbar 10.

From the foregoing description it will be obvious that one may control the movements of the carriage in both directions for paragraphing and tabulating by simple manipulations of conveniently positioned control devices and simple mechanism.

It will be obvious that various changes in the details, which have been herein described a and illustrated in order to explain the nature of the invention may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
