Tb on whom it may concern: Be it known that I, WALTER E. PALMER, a citizen of-the United States, and a residentof Cicero, in the county of Cook'and 5 State of Illinois, have invented certain new and useful Improvements in Type-Writing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin drawings, and to the characters of re erence marked thereon, which'form a part of this specification.

This invention relates to improvements 1 in tabulator mechanism for typewriting 18 maghinesand refersmore particularly to novefmeans' for controlling and positioningthecolumn stops of Mhich the carriage'is a rrested at predetermined, columnar positions in its travel for a series of items in vertical columns. Tabulator mechanisms of this char- 1, ioter usually' embrace, in combination with the carriage and the machine frame, a series of stop's supported'o'n one of the parts and 85 longitudinally adjustable with respect to I the path of the carriage travel, and a cooperating device or devices carried by the other part and adapted by manipulation of a key or'like device, to be shifted into oo- 80 operative relation with sa'id'column stops,

saidkey' usually operating at the same time to release the carriage from the control of its letter spacing mechanism so as to permltthe carriage to move under the influence ll ofits actuating spring to a point or points determined by the adjustment of the col imn sto or stops. j

" 'liave'herein shown my invention as apl plied to thetOliver typewriter of the gen- 40 en! construction illustrated in the prior patent to Knapp and Harting, No. 916,720, dated March 30th, 1909,but'it willbe understood that the essential features of the into other types of typewriting machines, and the invention is not, therefore, limited to the specific adaptati'on herein disclosed, except as tosuch claims wherein the particular structure is specifically'set forth.

drawings, 10 designates the longitudinal frame member of thecaron the forward margin of which is formed the rack 11 which engages with the 'ini0n 12 of the letter spacing mechanism.

he carria e is sup orted and travels on the rails 14 an which, for the purposes of (he presentin- 15 of the carriage shifting frame vention, may be regarded as a part'of the frame of the machine, or a frame on which the carriage is mounted for traveling movement. The said frame member 10 is provided with a depending..;flange or barll located just in'rear of a vertical transverse plane extendin throughthe rack 11. The

ar 17 is provi ed at;. its lower margin with 6 a plurality of ratchet, 'teeth' 18, adj acen'ti teeth being arranged a letter -space distance apart. This bar 17 is provided also on its front face with a scale marked to correspond with the. letter space scale of the carriage, and'with the spacing of the ratchet teeth 18.

Mounted on said bar 17 are a plurality of adjustable tabulator or column stops 20 of the form shown best in Figs. 5, 6 stop comprising members connects member, and arranged to embrace the lower toothed margin of member of each stop is provided at its 11 per end with a rearwardly projecting stu or pivot 21 received in a longitudinal roove 22 formed 1n and extending longitu inally of the bar 17 to enable a relative sliding movement and adjustment between said bar and stops longitudinally of the bar to be and 7 each 7 arallel front and rear by the lower transverse the bar 17. The front' effected; The transverse members of said stopsare providedhwith holdin teeth 23 adapted to engage the ratchet teet 18 of the bar' 17 to lock said stops in adjusted positions on the flange. The said stops are normally held so that the teeth 23 engage with the teeth 18 of the bar 17, by means of the springs 25 attached to the stops and bearing against the flange in themanner shown in to Knapp and Harting,

N 0. 916,720. When a stop-1s swung downwardly about its pivot 'or stud 21, against the'po'wer of the-spring 25 of said stop, to

' teeth 18 of the bar 17, thereb the position shown the bar and a relative sliding movement be tween the ratchet bar 17 and the stop thus releasedmay be effected, andthe stop 10'- cated at any desired position along the bar.

When the stop is unrestrained its spring 25 returns the stop to normal position with the tooth 23 thereof engaged with the ratchet stop in its adjusted position. aid stops cooperate with a key actuated stop member 27 p'ivotally mounted on the shift frame, said stop member being movable vertically into and out of the path of the stops 20'. The stop member 27 is shown as formed on the rear end of the key actuated lever 28 which mounted on a suitable. bracket uated at about midway between the sides of lating in columns of different the machine. .T he lever an upwardly and rearwardly extending arm 29 which is connected by a horizontally ar ranged link 30 with the upper end of the shaft that carries the pinion 12 of the letter spacing mechanism. The arrangement ofthe parts is such that 'when the lever 28 is swung to move the stop member 27 into the path of the stops'20, said pinion will" be re-' leased from the rack 11 of the letter spacing mechanism so that the carriage will be free to move under the influence of its actuating spring to a position determined by the ad justment of the next adjacent stop 20. These features of the tabulating mechanism described above are, or may be, like that of the construction of the Knapp and Harting patent before referred to and constitute, in themselves, no part of the present inven tion. Heretofore in some tabulating mechanisms of this eneral type it has been customary when it is desired umn stops on their supporting member, to effcctvsuc'h adjustment by direct manual engagement, either when the carriage is in.

place on the machine frame or when the car riage has been removed from the machine frame to give freer access. to the stops; Where a great variety of work is done, as, for example,-in large ofiices requiring tabu widths, such adjustmentinFigs. 5 and 7, thej stop is freed from locking engagement with locking the i 28 is provided with to adjust the 001 of the stops to change the spacinstances as many as three hundred and sixty column stops which'are carried by the carriage and add materially to the weight production.

One of the main objects of my invention is to overcome some of the difliculties'pointed out above and tov provide a simple and eflicient construction in which the number of column stops employed need not be in excess of the number to be used at any .one time and in which means are provided to control the relative adjustment of such column stops.

A further object of my invention is to provide simple 'and eflicient key controlled means operable individually on the column stops to control the movement'of such stops into or outof engagement with the locking means by which the stops are locked to the part of the machine, such as the carriage for example,-Which carries them.

A still further object of the present invention is to provide means which may be operated by a single actuating key or like device to controlthe setting or adjustment of a plurality of column stops to vary the spacing of the tabulated work without removing the carriage or grasping the stops directly by hand and adjusting them to the desired positio I In the present Oliver construction it is convenient to associate the column stop settin adjusting, controlling,

device with, or mount the same This key is arranged midway or about midway between the sides of the machine and just to the right of the key lever 28. The key lever is ordinarily employed to release the margin stop member carried by the rear end of said key lever, from or move it out of the path of the right-hand margin stop 34. which is also adj ustably mounted on the ratchet bar 17, as shown in Fig. 41.

controlling, setting or desirable, in. thatapply it to adjust ng device is it enables me to readily a machine of the kind shown thereof, yet it 'is-"to behuderstood that the invention is not limited 'to this arrangement, but that said column stop controlling del vicc' maybe provided with separate actin I atinggkey .and may he constructcdx uid arran'ge'd 'in" a-"ma'n-ner other tlliin tliat indior positioningv on the usual.

\Vhile thisarrangement of the column stopwit'hout material change in the constrwrtion cated. {The said column sto rcontrolling thereof, in addition to adding to the cost of is made ri or adjusting device comprises, in general letter spacing mechanism and into the upper part of the pivots 21 of t shown somewhat enlarged, and be accomplished by cutting of the bar .17 to adapt Va 22, which receives the e stops 20. The groove 22 is this may away the metal finger- 36 and to permit the carriage to be moved freely without bringing the column member 27, and

steps or the carriage into contact with the ,finger 36. The said swingingmember 37 is provided at one side with alaterally extending pin 41 which normally lies a distance above; the upper margin of the key lever 32, andis adapted, when the rear-end of the key lev r is swung upwardly, to be engaged by the tter (as shown in ig.' 6). continued swinging movement of the key lever the contact of the lever with said in 41 serves to swing the member 37 forwar ly, and thereby swing the rear end of the finger 36-downwardly. Each column stop is provided at its upper end, and near themargin thereof and remote from the pivot .21, with an upwardly opening notch 42.

The relation of lator stop member 27 with the rear end of the finger 36 is such column stops 20- with said stop member 27,

located directly over the notch 42. of the adjacent stop, as indicated at the left-hand end of Fig. 51. Therefore, when the carriage is thus arrested by engagement of one of the column stops 20 with the tabulator stop it is found necessary or desirable to reset or adjust the column stop to bring it to the proper position relatively.

to the paper receiving the printed impressions, the key lever 32 is de ressed, as shown in Figs. 5 and 7 In llhlS' movement the lever ehgages the pin 41, and swings the member 37 forwardly and thereby swings" the rear vend of the finger 36 downwardly into the notch 42 of vthe adjacent column stop and swings the stop on its pivot to the released position or outofengagement-with its-locking means The column stop is finger 36 seated in the slot or client; on interlockinfiiengagement between the stop and finger, w ile the column stop is maintained thus engaged by the in the released, position, and

notch 42 to fine or retain the column stop or maintain'it' temporarily fixed while the carriage and stop bar 17 may be moved independently thereof in the direction carriage'either to the right or left. The

may be brou ht about either by hand, or bythe usual orwardor back-spacing mechanism, to thereby change tion of the stop -on its carrying member or bar 17 so as to eflect a relative adjustment .of said stop adapting it to arrest the carriage at a new point or column determining position. After a relative adjustment of the column stop has'been attained, the operator releases pressure on the key and a returning spring 43, connect at one end to the lever 32 and at its opposite end to the and the column stopis tin operation is efiected by a singlemanual y operable device, as the key lever 32.

When the setting or adjusting device is mounted on or associated with the ri hthand marginal release key, located over'the margin'stop member 33 of said key, the said stop member in'ay be provided with the upwardly opening notch 44 to receive the finger 36 when the atter is swung downwardly into engagement with the notched stop 20 and thus stiffen said fingder against lateral deflection, as will be evient. finger it may b'e'otherwise stiffened.

As hereinbefore explained, the key controlled tabulator stop 27 is arranged midway or about midway between the sides of the machine with its contact .face in, or approximately in a foreand aft vertical plane extending through therefore, a column stop be engaged with this tahulator stop 27 and the column stop be then released and held against'movement [by the controlling device 36-37 while the carriage is adjusted 'latively thereto, and a rengagement of the sto with its locking means 18 be 'efiected-w en the carria has reached the proper dposition where e carriage is to be arreste' by said stop, this will'result in a proper positioning of-the column stop. For example, if a column toarrest the carriage at leased stop will be he (1 until the cards reaches a position which is indicated by 30 on the'carri'age scale and then the column stop will bereleased and allowed to engage I the subsequent operation of the tabulating mechanism, the coiiperation of thetabulater stop 27 with this column 'stop will reset in a like manner, and'that such resetthe printing point. If,

of the travel of the I travel" or endwise movement of the carriage the relative posi- 1 member 37, returns the parts 32 and 37 to I the teeth 18 by its spring 'andis there ore- I In other adaptations of the setting 30- on the carriage scale, ,(tihenthe re? by the evice 36-3 the nick 13. During column carria go is effect an arrest the carriage scale.

If desired, the column stops may be positioned at the proper points while a sheet is in the machine and by direct reference to the sheet and the usual printing point inclicator. .For example, /it' the sheet should be ruled to divide the different columns the operator may hold'one column stop While the carriage is moved to bring the first line on the sheet just to the left of the printing point-indicator. The column stop may then be released and locked on the stop bar and so on until the different stops are positioned. During the subsequent operation of the tabulator the stop- 27 will cooperate with a column stop to arrest the carriage just after a line on the sheet passes-the printing point.

From the foregoing description it will be understo d that the'column stop controlling member 37 isoperable individually on the column stops; that said member constitutes a device by which the stops may be individually moved on their support to release the stops from their locking means 18; that said .member 36-3i' also constitutes a positioning device which is in the nature of latching means'cooperative with each stop to hold. it with reference to-said device while a relative adjustment in the direction of the travel of the carriage is effected between the stop bar and said stop; that this is true whether the said relative adjustment is effected in one direction or the other of the travel of the carriage, or to the right or to the left; that said device also constitutes means operable individually on the column stops to control the movement thereof into engagement with their locking means and into andout of operative position; thatthe setot' column stops and said controlling device are carried one by the carriage and the other by tlie'frame' on which the carriage travels, so that, the travel of the operative to bring the column 1 stops successively into cooperative relation with said device.

\Vhile I have herein shown one practical embodinieut my invention for controlling the column or tabulating stops to eflect-a relative adjustment between ,the column stops and the member by which 'they are supported, it will be understood that the invention is not limited to the construction herein shown, but is applicable to all tabulating mechanism. of this general character,
