CORPORATION OF NEW" YORK.

TYPEWRITING MACHINE.

Application flied January 27, 1923. Serial No. 615.201.

To all whom it may concern:

Be it known that I, EDWIN E. BARNEY, a citizen of-the United States, and resident of New Rochelle, in the county of \Vestchester 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 typewriting or like machines and more particularly to means for rapidly jumping the carriage to bring different columnar fields successively to the printing point.

The main object of my invention is to provide a comparatively simple yet highly efli r cient means of the character specified, and in which the jumping of the carriage from one column to the next is brought about in the main automatically and there is no necessity of detracting from the written work produced by occupying the time and hardening the mind of the operator with the actuation of a selected one of a series of keys each time the carriage is to be jumped from one column to the next.

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 accompanyingdrawings, wherein like reference characters indicate corresponding parts in the different views,

Figure 11 is a fragmentary detail perspective view of a part of the same.

I have shown my invention in the present,

instance embodied in a No. 12 Remington machine, only so much of said machine beingshown as is necessary to arrive at an understanding of my invention in its inclusion therein. It should be understood, however, that the invention is not restricted to embodiment in this machine but may be used in various styles of typewriting or like machines. The machines as a whole may be understood to be the same as the No. 12 Remington machine with the usual tabulator mechanism omitted and certain changes made therein, to be hereinafter indicated.

The usual spring driven carriage comprises a rectangular truck, and a platen frame in which is mounted a cylindrical platen 1. The truck comprises a front cross bar 2, a rear cross bar 3, .and end bars 4. The rear cross bar 3 is grooved to receive crossed rollers 5 which likewise are received ordinarily enable the platen frame and the platen carried thereby to receive a case shifting movement. In the present instance, however, the usual screw stops14, one of which. is shown in dotted lines in Fig. 2, are

threaded down to prevent a shift of the platen as fully pointed out in my co-pending application, Sr. No. 610,058 filed December 30, 1922, relating to the line spacing mechanism intended for use in this same'machine. i

paper table 15 at right angles thereto.

These guides with the paper table form a chute in which a work sheet 18 may be introduced and guided accurately to the throat between the platen 1 and a paperapron 19 at the introductory side of the platen. To further aid in the proper and rapid introduction of a work sheet into the machine, I have provided a deflector plate 20 mounted at its upper end on a pivot rod 21, supported at its ends in openings in the guides 17 and fixedly, though deta hably, held in place by a thumb nut 22. The deflector 20 turns freely on its supporting or pivot rod 21 and extends downwardly and rearwardly therefrom, and is supported at its lower edge against the rear side of the platen; the deflector being held at its bottom edge snugly against the platen by gravity. This defiector plate forms a fourth side of the chute and further aids in directing a rapidly introduced work sheet into the machine, and to the usual feed rollers, not shown. The chute as a whole may be adjusted longitudinally of the laten by the means sometimes employed in emington machines for providing for adjustment of the flanges or side guides 17, and which include slots 23 in the paper table to receive supporting devices connected to the flanges.

The carriage which is spring driven in the usual manner is controlled in its movement by the following means: Referring first to Figs. 1 to 8, inclusive, it should be understood that the usual feed pinion 24 is controlled by its esca ement devices in the same manner as in the o. 12 Remington machine at each actuation of a printing key or the space key. However, I prefer to make the holding dog 25 of the escapement with a flat working face instead of a beveled working face, for reasons which will hereinafter appear. The feed pinion 24 is operatively connected with the escapement wheel 26 in the usual manner, so that the two turn together in one direction, but the pinion is free to turn independently of the escapement wheel when turning in the opposite direction. A depression of a printing key (not shown) is effective to actuate the usual type bar actuated universal bar, and through arms 27 connected therewith transmit motion to a rock shaft 28, which in turn rocks an arm 29 thereon rearwardly. This movement is transmitted through a link 30 to a dog rocker 31, by which the holding dog 25 and the stepping dog 32 are carried, causing the stepping dog to be disengaged from and the holding dog to be engaged with a tooth of the escapement wheel. Releasingthe depressed key enables the dog rocker to return to normal position when the carriage ordinarily advances one letter space. The ordinary space key of the machine, and of which each of the arms 33 may be regarded as a part, is connected through said arms to a rock shaft 34 mounted at its ends in the base 35 of the machine. A rocking of the shaft by the space key is effective, through the usual train of connections, to actuate the dog rocker. Thus, an arm 36 secured to the rock shaft carries an adjustable member 37 by which connection is made with a lever 38 pivoted at 39, and the upper a m 40 of which standsin front ofi a lug 41 on the link 30. The arm 40 moves rearwardly on the depression of a space key and moves the link 30 rearwardly to move the dog rocker, the

parts ordinarily returning to normal position when the space key is released. The escapement mechanism as thus far described, preferably with the single exception hereinbefore pointed out, may be of the usual construction employed in the No. 12 Remington machine.

The feed rack which coacts with the feed pinion 24, is in accordance with my invention, especially constructed to aid in bringing about the results attained by my invention. In place of the usual feed rack I employ a compound or multiple rack comprising a plurality of sections or members, two being shown in the present instance. One such member is indicated as a whole by the reference numeral 42 and is mounted on the carriage in'the usual manner, and is like the rack usually employed except that it has some of its teeth removed, making a mutilated rack member of it. In the particular construction shown it will be seen, by referring to Fig. 3, that there are thirteen teeth removed at the part a of the rack, three removed at the part 6 thereof, and three removed at the part c. This rack member is rigidly secured by screws 44 to a frame 45 having forwardly extending arms 46 pivoted at 47 to upwardly extending lugs 48, the foot pieces of which are secured by screws 49 to the rear cross bar 3 of the truck. The rear end of the usual release lever 50 extends beneath. an end portion of the rack member l moved in either direction.

A rack-section ormember 51, having thirteen teeth in the present instance, is arranged parallel with and in the rear of the rack member 42 where the thirteen teeth are omitted at ca from the mutilated rack member 42. The rack member 51 is pivoted at its ends and near its upper edge, as at 52, to two plates 53 and 54 secured to the rear side of the rack member 42. The plate 53 is secured in'place by'screws 55 and 56, and the plate 54 by a. screw 57 which also secures the mutilated rack member to its frame 45; positioning the pins 58 and aiding in holding the plate in place. Mounted in this manner the rack member 51 is adapted to be turned rearwardly on its pivots 52, independently of the mutilated rack member, from the normal position shown in Fig. 6 Where its teeth 51 are adapted to mesh with the teeth of the feed pinion 24, to the position shown in Fig. 8, where its teeth are disengaged from the feed pinion. A spring 59 is anchored at one end to the'scre-W 56, and at its free end overlaps the rack member 51 and tends to hold it against displacement around the pivots 52 from normal position, and to return it to such position. It will be seen that the teeth 51 exactly equal the number of teeth omitted from the mutilated rack member at a, and that the teeth 51 correspond in their spacing .and positions longitudinally of the rack to the removed teeth from the mutilated rack member at this portion thereof. It follows therefore that when said rackmember 51 is maintained in its normal position a step-by-step letter space feed of the pinion 24 will control the carriage to afford astep-by-step letter feed of the carriage, just asthough there were no teeth omitted at-this point from the mutilated rack. However, when the carriage is in's'uch position that the teeth 51' engage the feed pinion, and the rack member 51 should at this time be tilted on its pivots 52 to disengage the pinion as shown in Fig. 8, then the carriage will travel to the left free from control until the first tooth 42 of the mutilated rack to the right of the space (1 reaches the feed pinion and arrests the carriage.

I have provided means whereby the rack member 51 may be moved to the disengaging position as described. In the construction disclosed in Figs. 1 to 8, inclusive, such means are shown controlled by the space key of the machine. Thus an arm 60 is secured by a screw 61 to the arm 36 to turn therewith when the space key is actuated.

of As the printing key returns to normal posi- The rear end of this arm 60 is pivotally connected to an upright push rod, contact device or releasing member 62, which extends up through a guide opening in an arm 6301 the supporting bracket for the escapement wheel shaft. The upper end of this rod is beveled at 64, and at the rear side thereof is provided with a locking memher or hook-like-engaging portion 65.

In the normal position of the parts, shown in Fig. 1, the upper beveled end of the releasing rod 62' is situated beneath the line of travel of the lower forwardly turned edge 66 of a contact device, member or plate. 67. The latter is bent forwardly at 68 and attached by rivets 69 to the rear side of the rack member 51. The engaging edge 66 of the plate 67 corresponds substantially in length to the len th of said rack member 51, although said ed ge-is off-set from the body portion of the plate which is secured to the rack member.

The construction and relation of the parts are such that whenever the carriage is moved to a position where the teeth 51 engage the feed pinion 24 the edge 66 of the plate will be above the effective end of the releasing rod 62. An elevation of said rod at this time will be effective to move the rack member 51 out of engagement with the pinion, as shown'in Fig. 8. The act of disengaging the rack member 51, as stated, brings the bent end 66 of the plate behind the bill of the hook and interlocks therewith, as shown in Fig. 6. This interlock ing engagement holds the rack section 51 against return movement and locks the space key and the parts controlled thereby, including the rod 62, against returnm'ove ment The carriage is now free to travel until'arrested by the-tooth 42 of the rack 42 coacting with the feed pinion, as hereinbefore explained. This movement of the carriage is effective to carry with it the plate 67, and just before the carriage is arrested the edge 66 of the plate passes beyond the hook 65 and releases it, thereby automatically releasing the lock and permitting the rack section 51, the rod 62, the space key and the remaining parts controlled thereby to return to normal position. When the carriage moves to a position where the tooth 42 passes the teeth of the feed pinion 24, the carriage will automatically jump three spaces from one columnar,

position to the next. This is at the point 5 on the rack 42 where three teeth are. omitted therefrom. and the carriage is arrested by the tooth 42 ooacting with the feed pinion. A single printing operation at this point can be effected, usually with one the logotype bars 70, shown in Fig. 5.

tion the carriage will.

automatically ski three letter spaces to the next columnar posl column 76, which tion, where it is arrested by the tooth 42 coacting with the feed pinion. Ordinarily a single code character is written in this column. Usually there is nothing written in the next column until the charge slip 18 for the entire month has been filled, then the total at the foot of each column is entered and the grand total is entered at the foot of the last or total column.- However, in the event that it is desired to fill in a cross total at each line, this may be done by actuating the space key once after writing the code character, in order to bring the carriage in position to begin writing in the last or total column. If desired the same end may be attained by removing the tooth 42 from the rack member 42 and the corresponding tooth 54 from the member 54, and the carriage will then automatically jump one space in position to begin writing in the last column when the depressed printing key is released after having written the code character.

The range of travel of the carriage may be determined by a stop 71 fixedly secured to the forward fixed guide rail 72 by screws 73, and co-operative with theusual adjustable margin stop 74 and the usual adjustable line lock stop 45. The stop 74 may be set to determine the position of arrest of the carriage to write within the first columnar field, and may be adjusted to determine the number of characters to be written within said field, as will hereinafter ap ar.

In the present instance t e machine has been specially constructed and designed to write within columns, of given character and spacing, of a special blank form known as a toll service charge slip used by telephone companies, and illustrated at 18. Specific reference will be made to this blank in describing the detailed operation of the machine in filling it in. This blank is divided into six columns, i. e., the date column 76, the place called column 77, the amount column 78, the tax column 79, the code column 80, and the total column 81.

The operator places the slip 18 in the machine as shown, either to enter the first charge or to enter an additional charge on a slip having entries already included thereon. Usually only a single line ISWIIttBIX on the slip at a time and a great many are handled so that the saving of time in making an entry is of the utmost importance.

The slip having been introduced into the machine and positioned to receive a llne of writing, the carriage is moved to the ri ht until arrested by the stops 71 and 74. T is positions the carriage to enter the date in the may have a caption show- The day of the month is spaced by the igit is writing the month. Q then entered and the carriage letter space key. If only one the hundredths position.

ten in the column 76 then the space key should be actuated twice to bring the next column 77 to the printing point. If two digits are written then a single actuation of the space key is required. If desired the margin stop 7& may be set at, say, the point indicating nineteen on the carriage scale for writing the single digits indicating the dates from 1to 9, and for the remainder of the month in writing from 10 to 30 or 31, the stop 7 4 may be set to permit the writing of two digits. In this manner asingle operation of the space key will always bring the carriage into proper position to begin writing from a uniform point in the column 77. In the specific example shown, entries in this last mentioned column are intended to designate the place called and usually the name entered is abbreviated as NY for New York, BK for Brooklyn, etc. Such abbreviations or other entries should in all cases be made without actuating the space key and'is usually made continuous. If, however, the operator should desire to separate parts of the name or an abbreviation thereof,

this may be done with the aid of a hyphen or other suitably printed character, thus New-Mexico or thus N Y. The writing in this column 77 is effected when the space a in the mutilated rack 42 is at the feed pinion, and the teeth 51 of the rack member 51 are engaged therewith. At this time the releasing plate 67 is over the releasing rod 62, where it remains until just before the rack tooth L2 reaches the feed pinion 24, when the plates 67 pass said releasing rod. After an entryhas been made in the column 77 the operator depresses the space key and effects a release of the rack member 51, at the same time automatically locking such rack member in its freed position and the space key depressed. The carriage is thus freed from the control of either rack section and travels to the left until the tooth 42* reaches the feed pinion. This arrests the carriage in position to write the amount in the column 78. The last part of the movement of the carriage to this position is effective to automatically release the locked rack member 51 and the space key, and they return to normal position. Usually two, and sometimes three, digits are written in the column 7 8. 1f three digits are to be written, then the operator holds the space key depressed until after the first of the three digits are written. This prevents a let-off or advance of the carria until after the first di it is written in i but two digits are to be written, one in the tens and the other in the units column, then the operator actuates the release key in the ordinary manner; releasing it before writing in the tens position. The return of the dog rocker after writing in the units position in column 78, is effective to permit the tooth I from and permit the carriage to automatically jump three letter spaces, when the tooth 42 engages the feed pinion and arrests the carriage in position to write the code character in column 80. As hereinbefore pointed out, usually there is no cross footing of the individual amounts in the total, or final column 81; the total usuall being taken at the foot of each column an the grand total entered at the foot of the total column. However, should individual cross totals be desired the operator may, after entering the code character in column 80, depress the space key once, skipping one space, and bringing the column 81 to position to begin writing the cross total if it comprises three digits, or the operator may space twice with a space key if the total comprises two digits. Then again, if individual cross footing is'de. sired the tooth. 42, and one or more to the right of it, may be omitted from the rack section 42, as hereinbefore explained, so that the carriage will automatically jump to the last column 81 after the code character is written" in column 80.

While I have explained 1n detall arrangements of the teeth on the rack members 42.

and 51 to accord with the specific character of the blank shown, it will be understood that various arrangements of the teeth may be made, depending on the work to be done,

or the specific character of the blanks emplo ed.

'I he object of providing a flat face holding dog 25 instead of a beveled face holding dog is to effectively hold the carriage aga nst accidental ski ping or advancin during the operation 0 the space key, and or positively and effectively holding the carriage against advance movement, for writing within the proper denominational position either befor'eor after releasing the space key, in the manner hereinbefore explained.

In order that the entire impact of the carriage may not come on a single tooth of the rack member 42 when the carriage skips fromone' columnar osition to another, I prefer to provide additional teeth to receive such impact. =To this end I provide the plate 54 with seven teeth 54", 54", 54, 54, 54, 54, 54, positioned so that each matches a corresponding tooth of the rackv member 42. It will be understood therefore that each of the teeth 54", 54 and 54 together with its respective companion the space key, whenever the carriage is in position tobring. the two releasing devices or members 62 and 67 into co-operative relation, invariably releases the carriage and permits it to jump to the next columnar position. However, at all other points in the travel of the carriage an actuation of the space key may be e ected to bring about a letter pace movement of the carriage in the usual manner, and is ineffective to release the rack member 51. It will also be seen that the carriage automaticall jumps to the next columnar position w enever the spaces 6 and c of the rack, member 42 reaches the feed pinion 24. This construction therefore cannot be employed as an ordinary typewritingmachine for straight correspondence work, .for example. However, in the modified form of construction shown in Figs. 9 to 11 inclusive, the machine can be so employed, as well as for tabulating work of the character hereinbeforepointed out. In thismodified form of construction the carriage instead of be ing released by the space ke of the madesignated by the same reference numerals.

Instead of a comparativel short rack section lIke the sectional, w ich contains but thirteen teeth, I employ in the modified form of construction a rack member 82 having a complete set of teeth 82, one for each letter space position to which the carriage is capable of. moving. These teeth match the teeth of the rack member 42, which is like that previously described. In this instance there are also teeth on the rack meinber 82 where teeth are omitted from the member 42 at all three places, a, b, and 0 thereof, and in each instance a tooth 82 is positioned longitudinally of its rack where a tooth is omitted from the member 42. In other words, there is a tooth 82 for every tooth in the rack member 42 and also for every one omitted from the member 42. Like the former construction the rack 82 is pivoted at its ends and Martha upper edge thereof as indicated at 83, said pivots being supported in plates 84 secured by screws 85 to the rack member 42. Openings 86 are provided in the member 82 to receive the screws 44, by which the rack member 42 is secured to its carrying frame 45, without interfering with the member 82 resting against the member 42 in the normal siat their free ends against the rear face of the rack member 82, to hold it in and return it to its normal position, shown in Fig. 9. These springs are secured at their forward ends by screw 88 to the frame 45. In this construction the releasing member 89 corresponds to the part 67 previously described, except that it is longer and does not pass beyond its co-ope'rative releasing memer 90 until the tooth 42 engages t e feed pinion; no further tabulating beyond this point bein done in the present instance. The releasing member 90 isin the nature of a push rod pivoted at its lower end to a crank arm 91 projecting from a rock shaft 92. This shaft is mounted at its reduced ends in bearing openings in forwardly projecting arms of a bracket 93, secured by screws 94 to the base 35 of the machine. The bracket 93 also carries two arms arranged one above and the other below the arm 91. Each arm is provided with a set screw 95 which coacts with the arm 91 to limit its movement, and the movement of the parts connected therewith. A second forwardly projecting crank arm 96 on the rock shaft is slotted at its forward end, as indicated at 97. Thi slot receives a pin 98 projecting laterally from the rear end of a lever 99, fulcrumed on a rod 100 and provided at its forward end with a key 101, arranged in the keyboard of the machine. A spring 102 is coiled around the shaft 92 and is anchored at one end 103 against the bracket 93, and bears at its other end 104 down on the arm 90. This spring returns the rock shaft 92 and all of the parts connected therewith to the normal position shown in Fig. 10.

It will be seen that the upper end of the releasin rod 90, unlike the rod 02, is not provide with a hook like engaging member to coact with the member 89. In this construction therefore the parts are .not locked in operated position but may return to normal position when the special key 101 is released. This is done so that the key may, if desired, be actuated to tabulate at any one of each of the points I), c, as well as a, where the teeth are omitted from the rack member 52.

So long as the special key is not depressed the machine ma be used as a straight correspondence mac ine, the carriage feeding only a letter space distance at each actuation of a printing key or the space key. However, when the carriage has brought the member 89 into co-operative relation with the releasing member 90, then a tabulating operation is efiected at each depression of the key 101. If teeth be omitted from the rack 42 at various points throughout the len th thereof, then the member 89 is lengthene d accordingly, so as to be effective to release the same by the key 101 whenever an untoothed portion of the rack reaches the feed pinion.

The machine embodying my invention has proved highly efficient in practice, enabling an operator to introduce, fill in and remove slips with great rapidity.

It will be seen moreover that the ordinary N0. 10 or No. 12 Remington machine may be readily converted to embody the features of my invention.

Various changes may be made without departing from my invention as it is defined in the accompanying claims and certain features thereof may be employed without others.
