To all whom it may concern.

Be it known that l, SAMUEL M. citizen of the United States, residing in Kosciusko, in th county of Eittala am; State of Mississippi, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a speci fication.

This invention relates to an improvement in typewriting machines, and more particularly to mechanism for positioning the carriage in any selected column, in connection with the operation or" spacing the paper for a newline of writing, although some few tures or". the tabulating mechani m may be used without line-spacing operation or mechanism.

This invention discloses a tabulating 0r column-selecting mechanism which may be used to select rapidly the starting position or the platen for beginning a new paragraph. The selection of a column or carriage position may be made either with or without the line-spacing of the platen. As the carriage is returned to commence a new line, the carriage may be stopped at the inset point, corresponding to the beginning of a new paragraph and at the new line ready to write. The column selecting may be done either by a backward or forward movement of the carriage according to the position thereof. The mechanism preferably includcs a series of keys carried by the carriage, any one of which may be operated to move-a stop carried by the carriage into a position to engage a comparatively fixed stop carried by the typewriter frame, so as to obstruct the return movement of the carriage. This will limit'the extent of return movement of the carriage and thus determine the beginning of a new line.

The keys when operated in returning the carriage and also determining the beginning of a new line, may operate the line-space mechanism, as the line-space lever extends upwardly into the path of operation of the column-selecting keys.

The stops carried by the carriage and op erated by the column-selecting keys are double-acting and provided with two projec tions, one for engaging the fixed stops on the return movement of the carriage, as explained above. and the other for engaging he fixed stops on the ac vanoing movement oi the carriage. That is to say, in addition to positioning the carriage and returning it, the keys carried by the carriage may also be used to determine the position of the carriage when the latter is moved in an ad vancing direction. The determining of the position of the carriage on a return movement is by an operation of one of the keys in the manner in which the line-space mechanism. is usually operated to return the carriage. For a positioning of the carriage by an advancing movement thereof the keys carried by. the carriage are moved in the op posite direction, so as to bring one of the projections, according to the particular key selected, in line with one of the fixed stops on the typewriter frame. The movement of one of the keys in this direction does not drag the carriage along, 'but releases it from the escapement mechanism, so that the spring-barrel normally used to advance the carriage causes the same to jump forward until the selected stops cooperate with each other to bring the carriage to a haltat the position selected.

During an advancing tabulating movement of the carriage, the actuated key is locked in operative position until 'the se lected stops engage with each other. When the latter takes place, the key becomes released so that it may return to its normal position, thus permitting the feed rack to drop hack into engagement with the escapement pinion.

The fixed stops are on separate racks, ar-

ranged at different levels and secured to the typewriter frame. The carriage-stops are in the form of pivoted double-acting dogs extending between the racks, on which the fixed stops are adjustably mounted. The obstructions on each dog, forming a stop, are disposed on opposite sides of the racks, so as to he moved alternatively into the range or the fixed stop which cooperates therewith nism on the carriage to that on the typewriter frame.

ward a point. where the stop operated by the key will come into engagement with a fixed stop.

Fig. 3 is a view similar to Fig. 2, except that one of the keys has been operated in'the opposite direction to the operation in Fig. 2, so that one of-the carriage-stops has been moved in the opposite direction from that of Fig. 2, to enable it to engage an obstructing fixed stop as the key which brought it into play returns the carriage to the beginning of 'the next line. This key is also shown as having operatedthe linespace mechanism. to rotate the platen for the next line.

Fig. 4 i an enlarged view, similar to Figs.

2 and 3. All of the cglumn-selecting keys are shown in their inactive, intermediate position, with all of the projections on the carriage-stops clear of the range of obstruction of the" fixed stops. Fig. 5 is a detail view, looking'from front to rear at one of the fixed stops, showing the means of adjusting it along its supporting rack, and also showing the relation of the obstructing projections on the corresponding carriage-stop to this fixed stop.

Fig. 6 is a vertical section, taken from front to rear throughone of the fixed stops, and showing the manner of adjustalbly securing it on its rack," and the relation of two of the carriage-stops with respect to the fixed stop.

Considering more particularly the separate parts of this invention asembodied in the form shown in the drawings, 1 indicates a typewriter platen which is mounted to rotate by .means 0 an axle 2 .on a carriage. 3. The carriage 3 has the usual step-by-step movement at the striking of the character keys (not shown), in a manner common'to Underwood standard typewriters. This includes a rack. 4c, pivotally mounted on the carriage 3 and normally engaging a pinion 5', forming part of the escapement mecha- IllSIIl.

way pawl-and-ratchet mechanism 6 fixed to ation of the character keys, so as to release the escapement wheel step by step. The carriage and thus the platen 1 is given a This pinion 5 is connected by a one- 1 letter-feeding movement by the usual springbarrel 7* under the control of this escapement mechanism.

The platen 1 may be rotated major amounts by. means of the usual hand knobs 8, provided atthe ends of the axle 2, and

may also be moved line-space amounts by means of the line-space mechanism quite similar to that provided upon the standard Underwood typewriter. This line-space mechanism includes a line-space lever 9,

which is provided with an arm 10 engaging a slide .11 to move the latter against the tension'of a return spring 11*, Fig. 4. The

slide 11 is provided with'a pawl 12, which engages and operates a line-space wheel 13 as, for example, for a new paragraph, there are provided a plurality of keys '14, in this case shown to [be mounted on the carriage 3.

hese keys are 'in the nature of columnselecting keys and they may determine the position of the carriage 3 for difierentzones or major columns when the carriage is moved either in an advancing or a return direction. When the position of the carriage to be determined for a return movement, the keys 14 themselves may be used to return the carriage. -The keys 14 are pivotally mounted at 15 on a' compound bracket 16, extending reanwardly on the car- 'riage 3. These keys are provided at their front ends with finger-pieces 17 having inscribed thereon the particular column which they determine, such as 1, 2, 3 and 477 The line-s ace lever 9 has an operating handle 18, w i'chextends up in the path of movement of the keys 14, so that'when they are moved in a direction .to return the car-' riage 3 they at the same 'tiine operate the line-space lever 9. to rotate the platen to a new line. I

Each of the keys 14 is provided with a I i stop .24, which may be. termed a carriage stop, in that the keys Mare carried by the. carriage 3. These stops 24= are-shown in the form of dogs pivoted at 25 on their corr responding keys 14. A spring '26 is provided for'each key 14 and-itsassociate'd stop 24 tends to yieldingly hold the stop in a normal position" relatively to the key, which is determined by a pin 27 engaging an arm;

28 on the key 14a Each stop 24' has a pa.i r of

projections

29 and 30, which 'form obstructions engage alternatively on opposite sides the fixed stops 31, according to the direction of movement of the carriage and the character of operation of one of the keys 14. The

projections

29 and 30 are .abrupt on one side and cam-shaped on the other side. This enables them to be ob.- structed by the stops 31 when in their active positions and moving in one direction, and to yield to one side when engaged by the stops 31 and moving in the wrong direction.

The stops 31 are adjustably mounted on racks 32. There is one'of the stops 31 on a corresponding rack 32 for each of the corresponding stops 24, and thus for each of the column-selecting keys 14. Thestops 31 may be termed fixed stops, in that after once adjusting them, they are fixed on the racks 32, which, in turn, are supported by the typewriter frame 33. The racks 32 are held spaced relation by means of brackets 34, which have parallelly-extending reaches 35, on which the racks 32 are directly mounted. These reaches 35 extend toward the front of the machine, so that the keys 14 can extend between the racks 32, and also so that the carriage-stops 24 can extend between the racks 32, and thus enable the obstructing

projections

29 and 30 to engage the fixed stops 31 selectively on opposite sides.

The stops 31 are adjustable along the racks 32, one or all of which maybe provided with a scale 36, so as to accurately determine the position of the stops 31 for different letter space positions of the carriage 3. The under sides of the racks are provided with teeth, whereby the stops 31 may be locked in any adjusted position byv means of latches 37 one of which is provided on each of the stops 24. The latch 37 is hinged at 38 to the body portion of the stop, and is normally held in the full-line,

locked position shown in Fig. 6, by means of a spring 39. In this position a tooth 40 on the latch 37 engages between two teeth of the rack The latch 37 can be depressed to the dotted-line position'of Fig. 6 to enable a stop 31 to be adjusted along the corresponding rack 32.

The projections 29 on the stops 24 are used to engage the fixed stops 31 at 41, whereby the stops 31 are extended to form a projection when the keys 14 are used to return the carriage and determine the position of the carriage during such return movement. The projections 30, on the other hand, are used to determine the position of the carriage during an advancing movement of the latter by engaging projections 42, one of which is provided on each fixed stop 31 on the opposite side from the projection 41. When a projection 42 is used to determine the position of the carriage by anadvancing movement of the carriage, the corresponding key 14 is moved to the position illustrated in Fig. 2. When moved in this direction, a: cam 43, provided on each letter-space position key 14, engages a vertical rod 44 extei' between

arms

45, 46, pivoted by a sha'tt 47. and forces the

arms

45, 46 against the tension of a spring -13 from the Fig. 4 position to the Fig. 2 position. The arm engages an arm 49 provided on a key-lever 50. The key lever 50 is used to raise the carriage rack 4 out of'mesh with the pinion 5. Thus, when one of the keys 14 is moved to the left, as shown in Fig. 2, it will operate key-lever 50 to disengage the carriage-from the escapement mechanism, so that the spring-barrel will be free to advance the carriage until its movement is obstructed. The limit of movement will be determined by the particular key 14 operated in this manner, which brings its projection 30 to a position to come into engagement with the corresponding stop 31 which lies in the path of travel of the stop 24. During this tabulating movement of the carriage, the ac tuated key. is held in its ineffective position by the bar 44, which, it will be remembered,

is common to all of the keys. This is done by providing each key 14 with a depression 43 at the end of each cam 43, into which the bar 44 may drop at the end of the efi'ective movement of the key 14. When the projection 30 of the stop 24 engages with the fixed stop 31, the impact of the carriage is suiiicient to draw on the key 14 and release it from the bar 44, after which the bar 44 becomes effective through the intermediary of the spring 48 and the cam 43, with which the bar 44 engages, to fully restore the key 14 to its normal or ineffective position.

The keys 14 are locked in t .ir intermediate, idle position, with both of the proections 29 and 30 out of range of the stops 31, by means of detents 51. There is one of these detents for each of the keys 14. Each of the detents 51 is in the form of a strip of thin metal, having a raised portion 52 engaging in a socket 53 provided on the corresponding key 14.

Considering the operation of the device, each stop 31 is adjusted along its bar 32 to a correspondin to a point of a major column or Zone-of t e carriage at which it is desired to stop the carriage when the corresponding key is operated. The keys 14 normally occupy an intermediate position, such as that shown in full lines in Fig. 4, and may be shifted in.

dividually to either side of this neutral position to determine zonal positions of the typewriter carriage.

The keys may be used to determine automatically the indentation for a new paragraph. This takes place after a line is completed, and it isusually necessary to return the carriage so that one of the keys 14 may be operated to return the carriage and at the same time determine the extent of-return of a-return or an advancing movement of the the carriage. When one of the. keys 14 is carriage, according to the partlcular posiused in .thls manner, the particular' key 14 tion of the carriage and the particularzone operated will alsooperate the line-space or major column desired.
