TYPEWRITING-MAGHINE Specification of Letters Batent. Patented M 15 1921 Application filed July 6, 19%. Serial No. 894,2 25.

To all whom it may concern Be it known that I, OsoAR WOODWARD, citizen of the United States, and resident of Babylon, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

My invention relates to typewritin machines and more particularly to tabu ating mechanisms therefor.

l-leretofore in certain kinds of column selecting mechanisms the constructions were such that any desired column could be selected at will; but where the operator desired merely to use the tabulator to jump the carriage to successive columns, or from one column to the next throughout successive fields, it was necessary to operate the selecting keys successively, say, first the number 1 selecting key for the first column, then the number 2 selecting key for the next column, and so on. This entailed on the operator remembering which selecting key was last operated, or an inspection of the work in each instance to determine the position of the next column to be selected, and then a selection and operation of the corresponding or proper tabulator key. This resulted in confusing the operator, diverting the operators attention from the work in hand, and in loss of time that might have been advantageously usedin the production of more wor and sometimes resulted in mistakes which caused further confusion and delay.

The main purpose of the present invention, generally stated, is to provide simple and effective means by which these defects or objections may be overcome and whereby any one of the set of column selecting keys I by repeated strokes thereon, or whereby successive strokes on different selecting keys may be used to jump the carriage successively from one column to the next without however destroying the availability of the mechanism to be used for column selecting purposes when desired.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters designate corresponding parts in the various views,

F 1g. 6 is a detail fragmentary rear perspective view of the stop har and five coiumn stops mounted thereon.

The present invention is in the nature of an improvement on the construction disclosed in my application filed January 3, 1920, Serial No. 349,192, in which certain of the above mentioned results are accomplished. In the said co-pending application the construction disclosed is such that when the parts are set for use in writing in successive columns it is necessary in order to efi'ect such result 'to actuate always a given one of the column selecting keys, whereas in the present construction an actuation of any one of the series of selecting keys is effective to attain the same result, thus relieving the mind of the operator from the necessity of remembering which key' to V actuate to effect column to column work, and further avoiding any chance of error by the operator actuating the wrong key.

I haveshown my invention in the present instance embodied in a No. 10 Remington machine which includes column selecting mechanism of the character disclosed in the patents to George Seib, Nos. 1,132,286 and 1,273,54E5, dated respectively, March 16, 1915 and July 23, 1918. In such mechanism each selecting stop when coacting with any The frame of the machine includes a top plate 1 on which a carriage 2 is mounted to travel from side to side of the machine, the carria e carrying the usual cylindrical platen 3. cured to the carriage near the ends thereof support a column stop bar 5 formed with teeth 6 on opposite sides thereof.

Column selecting mechanism of the character shown in the above mentioned Seib patents and similar to that employed in the N o. 10 Remington machine is provided to coact with the column stops carried by the column stop bar 5.

' The tabulator frame 7 is secured by screws 8 to the top plate of the machine and supports pivoted selecting levers 9, each of which terminates at its upper end in a forwardly extending finger 10 which coacts only with its particular pivoted column selecting stop 11. It follows therefore that each column selecting key a is operative through the intermediate connections to actuate its companion lever 9 and therethrough to project forwardly the particular selecting stop 11 with which said lever coacts.

The selecting stops are arranged one .above another in different horizontal planes and each is adapted to swing forwardly on its pivot 11 in a fixed path or invariable plane which difl'ersfrom the planes of movement of all of the other stops 11. This is effective ordi:

narily to bring the projected stop 11 into cooperative relation only with the particular stop projection or arresting face on the par ticular counter or column stop with which it is to coact. Each of the column or counter stops is designated as a whole by the reference numeral 12. These column stops are constructed somewhat like the column sto s disclosed in the application of Elbert Dodge, Serial No. 268,252 filed December 26,

'1918. Thus each stop is formed with a central body portion 13 bifurcated to receive and straddle the column stop bar. Two

sheet metal side plates 14 are riveted at 15 on opposite sides of the body portion 13 of the stop. Each sheet metal plate 14 is like- I wise bifurcated to straddle a stop bar. but

the inner parallel walls 14 of the plates extend inwardly farther than the body portion 13 ofthe'stop to enter spaces between arwardly projecting arms 4 se-' theteeth 6 on the stop bar. Each stop is provided with a finger piece 16 and with a suitable detent to retain the stop against accidental displacement from the bar. In the present instance this detent comprises a ball 17, expansion spring 19, and adjusting screw 19, all arranged in a socket or aperture 18 formed in the body portion 13 of the stop at the forward edge thereof as the parts appear in Fig. 3. The stops may however be readdistinguished in the drawings I have designated them by separate reference characters '20, 20 20" 20, 20. It will be seen from the foregoin that an operation of the highest, selecting stop 11, by its associated selecting key a, bearing the index numeral 1, results in moving that selecting stop into the path of travel of the projection 20 on the right-hand column stop as the parts appear in 6, said selecting stop 11 being ineffective on all the other column stops. So it is with the other column selecting stops 11, each being cooperative only with the particular column stop (20, 20', 20 or 20) with which it is supposed or intended to coact. With this arrangement it is necessary, should the operator desire to move the carriage successively from one column to the next, to operate the selecting keys 0; successively in the one, two, three order, as hereinbefore pointed out.

' In order to avoid the confusion and errors 'which may result in using the tabulator to jump the carriage to successive columns in the manner described, I have provided each column stop with an additional stop projection, engaging member, arresting face or contact 21 which as shown in'the present instance projects in the opposite direction from the series of stop projections 20, etc., hereinbefore described; or in other words this additional stop 21 is provided on the side opposite the stops 20, etc., and .is formed as a part of the body portion 13 of the stop member. These stop projections or contacts 21 are all alike and all have the same path or plane of movement, so that when the column stops are detached and reversed on the stop bar 5 from the Fig. 1 to the Fig. 4 position each of the projections 21 is adapted to coact with each and all of the selecting stops 11. In other words, the

and their interposed guide or division plates 11*. The path of movement of each contact- 21 therefore corresponds to the combined paths of movement of the contacts 20, 20,

etc, and is vertically disposed and crosses the planes of movement of all of the selecting stops 11. It follows therefore that when the contacts 21 are in operative position each of them will coact with all of the column selecting stops 11. A projection of any of the latter to operative position, therefore, will bring it into coiiperation with the contact 21 on the first column stop that reaches it. A repeated operation of any one of the selecting keys at, or a successive operation of the different keys (D, will always result in the carriage being moved successively from one column to the next irrespective of the key or keys actuated. The mind of the operator is therefore not burdened with remembering the order in which the keys must be actuated, or which key was actuated last, or the particular key which must be repeatedly actuated to obtain the desired result, as in prior constructions.

If the column stop bar be fixed to the carriage the column stops may be detached and reversed as pointed out above. However, the column stop bar may be pivoted at one end as at 22 to its supporting member or section 23, which turn is supported by one of the arms 4 of the carriage. in such construction a locking flange 2% is secured to the stop bar and is provided with two recesses 25 on opposite sides thereof. A locking latch 26 may be pivoted at 27 on the supporting member 23 and have a locking projection 28 at one end thereof which 1s adapted to be received in either of the recesses 25 in the locking flange and lock the bar against turning movement. A coiled expansion spring 29 interposed between the outer .end of the locking latch and the supporting member 23 maintains the latch in its locking position. The opposite end of the stop barin this construction is pivoted to a supporting member, corresponding to the member 23, in a like manner. By releasing the locking latch 26 and givingthe bar a half turn from the position shown in Fig. 6 all of the stop projections 21 will be brought to a position to coact with any selecting stop 11 controlled by the five selecting keys a. The advantage of this form of construction is that it is unnecessary to detach the column stops from the bar in order to bring either one set or the other set of stop projections into use.-

While I have shown five selecting sto s and five coacting column stops, it will be 'with a' given one of said selecting stops,

understood that the number of stops employed may be varied.

Various other chan es may be made without departing from t e scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of key controlled selecting stops each movable in a single fixedpath, and a series of counter-stops provided with two sets of arresting faces, each arresting face of one set coacting with all of the selecting stops, and each arresting face of the other set coacting solely with one of the selecting stops.

2. in a typewriting machine, the combination of a series of key controlled selecting stops each movable in an invariable plane, a series of counter-stops provided with two sets of arresting portions, each of the members of one set being arranged for cooperation with all of said selecting stops, the members of the other series being arranged in different planes corresponding to the difierent planes in which the selecting stops are located and each coacting only and means whereby the engaging members of either series may be brought into position for use.

3. In a typewriting machine, the combination of a carriage, and tabulator mechanism for arresting the carriage, said tabulator mechanism including two series of arres ing portions, those of one series having difi'erent paths of movement one from the other, and each of the arresting portions of r the paths of all of the arresting portions of the first mentioned series.

4. in a typewriting machine, the combination of a carriage, and tabulator mechanism for arresting the same, said tabulator mechanism comprising a series of key controlled selectln stops each movable always in a single Xed path which differs from the paths of movement of all of the other se lecting stops, a column stop bar, and a series of column stops mounted for individual adjustment to different points along said bar, each column stop having two arresting projections thereon, one series of said arresting projections being variably positioned on the stops so that each will co-act only with a given one of the selecting stops, and the other series being uniformly positioned on the stops so that each projection will coact with all of the selecting stops.

5. In a typewriting machine, the combination of a series of key controlled column selecting stops each having a separate and distinct path of movement, and a series of column stops each provided with a contact face of suflicient length to cross the paths of movement of the entire series of selecting stops, whereby the carriage may be arrested at each successive column irrespective of the keys actuated.

6. In a typewriting machine, the combination of a series of key controlled column selecting stops each having a separate and distinct path of movement, a series of column stops each provided with a contact face of a length sufficient to contact with one only of said selecting stops, whereby columns may be skipped, and provided also with a second contact face of sufficient length to cross the paths of movement of the entire series of selecting stops whereby the carriage is arrested at each successive column irrespective of the keys actuated, and means which enable either series of stop faces to be brought into use at will. a

7. In a typewriting machine, the combina- 'tion of a carriage, a series of key controlled selecting stops each movable in a difl'erent plane, a column stop bar, and a series of column stops adjustable thereon and each provided with an engaging member that travels in a plane which corresponds to the plane of movement of a given one only of said selecting stops,each column stop. also provided with an engaging member that crosses the planes of movement of allof the selecting stops so as to coact with each of them.

8. For use in a typewriter tabulating mechanism, a set of column stops each having on one side a short projection which has a different location from all other such projections on the other column-stops, and each OSCAR WOODWARD.
