Specification of/ Letters Patent.
Original application led March 27, 1905, Serial No. 252,216. Divided and this application led December 2, 1908. Serial No. 465,611.
To all whom Macy concern:
Be it known that I, HERBERT H. STEELE, citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writin Machines, of which the following is a speci cation.
Typewritin machines have heretofore been provide with tabulating mechanism that enable the operator to jump the carria e from one column stop to the next succee ing column stop, and where it is necessary to skip over certain columns the carriage must be released and arrested at each intermediate stop, until it finally reaches the predetermined stop and arrests the carriage at the columnar field where the desired entry is to be made. Another form of mechanism enables the operator to skip over any intermediate stops and arrest the carriage at any pedetermined columnar position, without ing temporarily stopped by the first or any intermediate column stops. Still another form of machine embodies the tabulating mechanism last described and also includes a second independently operable tabulating or denominational stop mechanism, first one mechanism and then the other being operated to cause the desired results. With this last form of machine, which includes both column and denominationalstop mechanisms, to print denominationally at any desired column, it is first necessary to arrest the carriage at the predetermined point by the engagement of the predetermined column stop with a cooperating stop and then to release the carriage a second time to bring the said column stop into engagement with a denominational stop, to arrest the carriage and bring a predetermined point on the paper to the printing position, whereby a series of numbers may be printed in units, tens, hundreds columns, etc.,within the same column field.
My present invention has for one of its objects to overcome this objection of successively arresting the carriage, when it is desired to skip over certain intermediate column fields and print denominationally within any predetermined column, by enabling the operator to jump the carriage at one operation or by one movement to any desired denominational position within any desired columnar field.
Another object ofthe invention is to provide mechanical means which enable the operator to release the carriage and then arrest it at any predetermined letter space position along the entire line of print by a single movement of the carriage.
Another object is to place the whole tabular mechanism at the front of the machine where it is more convenient than at the rear of the machine.
Another object is to define the columnar positions of the line of print on the index of the column stop sector or disk, by employing a clip or pointer that is movable along the edge thereof.
A still further object is to attach a tabulator guide index or chart at any desired point along the column stop sector or disk, to define each denominational position of print, within any defined columnar field.
A still further object of my invention is to provide a single mechanism operable to secure the proper arrest of the carriage at any desired denominational position Within any desired columnar-field.
Another object of my invention is to provide a tabulating mechanism in which a single actuation of a part is suflicient to determine the proper point of arrest of the carriage at any desired denominational position within any desired columnar-field. y
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 to be more fully described and particularly pointed out in the appended claims.
Figure l is a view in vertical section through a visible writing typewriting machine, showing my invention applied thereto; some of the parts being broken away and other parts omitted .for the sake of clearness. The section in this View is taken on the line mof Fig. 2. Fig. 2 is a fragmentary detail front elevation of the tabulating mechanism. Fig. 3 is a fragmentary rear elevation of the upper portion of the machine to illustrate the manner of releasing the carriage from the escapement mechanism. Fig. 4 is a detail front View of a modified form of tabulating mechanism showing a single column stop arranged to assume variable positions around the disk; a series of clips or pointers introduced around the edge of the disk to indicate columnar positions along the line of print, and a tabulating chart arranged to denote the denominational positions at the end of the line of print. section view of the same, the section being taken on the line y, y of Fig. 4. F ig. 6 is a detail plan view of the tabulating chart which in Fig. 4 is shown attached to the disk. Fig. 7 is a detail fragmentary transverse sectional view of the hand-controlled tabulator stop.
The main base frame 1, incloses the usual key levers 2, that may be fulcrumed at 3 and provided with front and rear combs 4 and 5 respectively. A restoring spring 6 cooperates with each key lever and maintains it normally in the elevated position. Each key lever is connected with a type bar 7 that is pivotally mounted within a suitable hanger 8 adjustably secured to the type bar segment 9. The forward end of each type bar normally rests on a pad 10 mounted upon a sector 11 toform a basket for the whole series of bars. The sector also supports a series of segmentally arranged hangers 12 each hanger having a lever 13 pivoted thereto and each lever 13 is connected with the associated type bar through a link 14 and is connected with the associated key lever through ay link 15. Each type bar `7 is adapted to swing upwardly and rearwardly and strike a platen 16 at the front thereof so that each character printed may be. visible from the front of the machine. The platen 16 is of the cylindrical type mounted upon a shaft that turns in bearings supported in a suitable carriage 17 comprising two end bars, a front bar 18 and a rear bar 19, each of the latter bars being provided with suitable ways to receive anti-friction balls or rollers 2() that engage with similar ways formed in the ordinary carriage rails 21 and 22 that support the carriage above the top plate of the frame and permit said carriage to move freely from side to side of the machine. The carriage is provided with a feed rack 23 that may be attached to 4pivoted arms 24 pivoted to the carriage and having a spring 25 that may be coiled around the pivots of said arms as shown, to force the rack down and normally maintain the teeth thereof in operative engagement with a feed pinion 26. The shaft 27 of this pinion is mounted in a stationary bearing 28 and an escapement Wheel 29 is operatively connected to the shaft in the usual manner and is coperative with suitable feed dogs 30 that afford the usual step-by-step letter space feed to the paper carriage. The escapement dogs 30 are mounted upon a dog rocker 31 having Fig. 5 is a central vertical a transverse arm 32 that is connected by rection. The usual carriage release key 39,
may be pivoted to an end bar of the carriage as at 4() and extends rearwardly to and beneath the end of the feed rack '23, in order to provide means to raise the said rack out of engagement with the pinion 26 when it is desirable to move the carriage freely in either direction. It should be understood, however, that so far as my present invention is concerned it may be applied to various styles of typewriting machines.
Vhile the carriage may be moved freely in either direction by the use of the release lever 39 as just described, for the purposes of my present invention, I prefer to use other means to release the carriage from its step-by-step feed or escapement mechanism when the tabulating mechanism is brought into operation. One way to accomplish this result is shown in Figs. l and 3. A lever 41 is pivotally mounted to a suitable bracket 42, made fast to the top plate of the machine, and said'lever is provided with a shoe 43 which underlies the feed rack Q3, and is situated at the right hand end of the lever adjacent the escapement wheel Q9. The outer end of said lever 41 is perforated to receive the end of a wire connection or link 44 that passes downwardly through the top plate and is connected at the lower end to the release key (Fig. 1), which is of the same general shape as the character keys, but is positioned so as to be depressible independently of the universal bar 34. I prefer to make the link 44 in the nature of a two-part link, the two pz1rts being united by a turn buckle 47 in order to obtain proper adjustment between the key 45 and the lever 4l.
The base frame 1 is usually formed with a stiffening brace 48 and on this brace, adjacent the center thereof, is mounted an upright bracket 49 that may be removably secured thereto by screwsI 50. The bracket is provided with an opening in which a short spindle or shaft 51 is received and fixed, forming a stationary axis or spindle for a toothed gear or sector 52 at the rear of said bracket. The shaft 51 likewise extends forwardly from said bracket 49 for purposes presently to appear. The Zfear is provided with a projecting n'iember, tabulating stop or dog 53 that may be rigidly fixed thereto by screws 54. A toothed rack 55 is adjustably fixed to suitable arms 56 that are fastened to the front bar 18 of the carriage.
The teeth of the rack 55 are always in engagement with the teeth of the gear 52, hence as the carriage is moved in either' d1- rection, the gear and its associated dog or' tabulating stop 53 will rotate through a fixed path and will move in unison with the carriage. The rack bar 50 is provided with graduations to indicate letter space positions along the line of print as shown in Fig. 2, the position of the printing point being indicated by a suitable pointer 57, thus forming a carriage scale and pointer.
To the front face of the bracket 49, is rigidly fixed as with rivets 58 or otherwise, a sector 59 having a series of radial slots 60 suitably spaced apart to correspond to the different letter space positions of the carriage throughout its travel, and each slot is indexed to correspond with the graduations on the rack 55. By referring to Fig. 1, it will be seen that the slots 60 are segmenta'lly arranged and correspond to the rotative path of movement of the dog 53, as it moves around its axis 51, under the action of the carriage. Thus, when the carriage is moved by hand or otherwise, so that the printing point will be at, say, 35, as indicated by the graduation 35 on the bar 55 registering with the pointer 57, the dog or tabulating stop 53 will be automatically positioned to register with the thirty-fifth slot in the disk 59, indicated by the index numeral 35 on the sector. Similarly, when the carriage has been moved to the extreme right-hand for the commencement of a line as indicated by the registration of the pointer 57 with the zero graduation on the carriage scale, the dog 53 will have moved along its circular path to register with the zero slot in the dial.
With the construction thus far described, the carriage has a free movement in either direction when released from the escapement mechanism and the dog 53 will traverse its circular path in either direction corresponding to the distance that the carriage is moved. To arrestthe dog or stop 53 at varying positions, by inserting a tabulating stop or arresting member through the slots 60 to intersect the path of said dog 53, forms a feature of my invention that will be next described.
On the shaft or spindle 51 that projects through the bracket` and through the bearing of the sector 52 is loosely mounted a rigid arm 61 provided with a plunger tabulating stop 67 and a coiled sprin surrounds the stem of the stop (see Fig. and bears at one end against the head or finger piece or key 68 of the stop and at its opposite end against the arm or the casing for the stop, to normally hold the stop away from the sector 59 and out of engagement with the slots 60. The arm 61 shown in Figs. 1 and 2 may be formed from non-resilient metal and adapted to rotate on its axis 51 with only sufficient friction to hold it temporarily in any position to which it may be adjusted around its pivot to the proper denominational position opposite a slot 60. The key 68 is then pressed rearwardly to interpose the stop 67 in the path of the stop 53. The carriage is then released and the carriage at the end of a single run will be arrested at the proper denominational position.
In Figs. 4 and 5 I have shown a modified form of the construction in which a disk 59EL is employed in place of the sector 59 previously described. In this modified construction a gear wheel 52a is substituted for the sector 52 of the previously described construction but like the sector 52 meshes with the rack 55. Like the sector 52 the wheel 52a carries a stop 53a. The parts of the modified construction in many respects correspond to those shown in the previously described construction and when the parts are essentially the same the same reference numerals will be employed to indicate them. The pivoted arm G1 in the present construction is resilient and carries a fin er piece or key 68a by which the stop 6 a is turned around to the proper position on the disk or dial and by which the stop is projected through the slots 60 against the inherent resiliency of the spring arm 61a and into the path of the stop 53a.
From certain aspects of the invention the construction shown in Figs. 1 and 2 is preferred to that shown in Figs. 4 and 5 since in the latter construction the stop 53a defines a circular path around its pivot, the stop being capable of turning through about three quarters of a circle and as the graduat-ions around the disk are arranged radially of the axis, it is sometimes more or less difiicult to readily read certain of the graduations. In the construction shown in Figs. 1 and 2 the use of the sector 59 overcomes the disadvantages inherent in the other' construction and presents the indices so that they can be readily seen and a proper adjustment of the stop may be more readily effected.
Around the edge of the slotted sector 59 or disk 59 may be arranged a series of adjustable clips or pointers 75 indicating the columnar determining positions as shown in Figs. 4 and 5. The first of the indicators shown in Fig. 4 is set at the index 12 on the dial 59 and indicates that the first column begins at twelve, the second at twenty-three, etc. When the arm 61a is shifted to register with the first pointer as shown in dotted lines, in Fig. 4, the stop 67a is in position when forced through the slot 60 to arrest the dog 53a in such position that the carriage will be arrested at 12 on the carriage scale, or in a position to write within a columnar field beginning at 12.
While the description thus far has been confined to the operation of releasing and arresting the Carriage at predetermined points for the purpose of printing within columns, it will be seen that with the arrangenlent of parts as shown in the drawings, the single movable stop 67 or G7a may be moved certain letter space distances from any columnar position and thus determine the arrest of the carriage at varying points or denominational positions within the columnar field, and providing thereby means to permit rows of figures being printed in properl denominational order, one beneath the other. In order to facilitate positioning the stop G7 or 67EL for coperation with the dog 53 or 53a so as to properly arrest the carriage at the desired denominational position within a selected column field or at the extreme end of the line, I provide a denominational chart or index 76 that may be adjustably attached to the sector 59 or to the disk 59a as shown at Fig. 4t, to indicate the proper positions for setting the arm 61 or 61a in order that the carriage may be arrested at the proper position to write at the desired denominational position within a columnar field. In the present instance the index 76 is shown set on the dial in advance of a point thereon, said point 70 corresponding to the normal point of arrest of the carriage at the end of a line. Ihenthe arm is shifted to the position shown in dotted lines to register with the index mark at sixty-two, the carriage will he arrested at a point to enable the operator to print, say, 10,000.0() in advance of the extreme travel of the carriage at 70. At Fig. 6 is shown a detailed view of this denominational chart, illustrating two overhanging ears 77 that embrace the edge of the slotted sector 59 or the disk 59:t and by which the chart or index may be adjusted around the dial or around the sector.
From the foregoing description of the operation of my invention it willv be seen that while the arm 61 (or Gla) and its asso- -ciated stop G7 (or 67a) constitute a column stop to arrest the carriage at the various predetermined columnar positions and at the same time permit the operator to skip over at will one or more intermediate columnar fields, it will also be seen that the arm and stop also constitute a denominational stop and allow the operator to print denominational positioned characters within any columnar-field. It will also be seen that when it is desired to skip over certain intermediate columnar fields and print characters at any desired predetermined denominational positions within any desired predetermined columnar-field, the carriage When arrested by the stop 67 (or 67a) is ari rested at once at the proper denominational position within the proper columnar field, and not as heretofore first at the columnar position and afterward at the denominational position. This feature of skipping intermediate columnar fields and jumping by a single tabulating operation and by a single movement of the carriage to a denominational position within the proper columnar field without first arresting the carriage by a column stop to define first the columnar field and then the proper denominational positioning within that field is novel with and is an important feature of my invention. To assist the operator in defining the denominational positions when shifting the arms and stops, the chart or index shown in Figs. 4, 5 and 6 may be used to indicate the proper location of any series of digits in order that columns of figures may be printed in. proper denominational order to bring units under units, tens under tens, etc.
The position of the differentcolumn fields at which the carriage may be arrested is indicated on the tabulator by the pointers 7 5, the arm 6l (or 61a) being shifted to register with any of these pointers and is then pushed rearwardly to project the stop (S7 through the slot 60 with which it registers as already described and the carriage will be arrested by the cooperation of the stops G7 and 53 or 67a and 53a. To print denominationally, the arm is shifted to register with the requisite index on the chart 7G as shown in dotted lines in Fig. 4t to arrest the carriage at the proper position to enable denominational positions of the written characters to be secured. The single stop 67 or 67a is arranged to intercept the stop or dog` 53 or 531 at any point in its movement, the points where the stops G7 and 53 or 67aL and 53d may be brought into cooperation correspondingl to the seventy letter space movements of the carriage in a complete travel thereof.
Ihile I have described certain mechanism as the embodiment of my invention, it will be understood that the same can be still further modified and still keep within the spirit and scope of my invention and that the invention may be applied to other designs of machines than the one shown in my drawings. methods of moving the stop G7 or (S7n to intersect the path of the dog or stop 53 or 53 may be employed. The term column stop`as used in the following claims is intended from certain aspects of my invention to designate any stop that determines a columnar position of arrest of the carriage, whereas the term denominational stop7 from certain aspects of my invention is intended to designate any stop that determines the denominational position of arrest ofthe carriage. The term combined column and denomination stop is employed from certain aspects of my invention to designate Thus, for example, other masas any stop that is empltyed, or is capable of belng employed, to etermine either the columnar position of arrest or the denominational position or to determine the proper denominational position of arrest within a given columnar field, Whereas t-he 'term tabulating stop, Whether applied to the stops 67, 67a 53 or 53, is intended to designate broadly a stop for tabulating purposes. Furthermore, other devices may be substituted for the dog 53 or 53a to arrest vthe carriage b the coperation therewith of suitable ta ulating devices and the use of the terms do and rotating dog or rotating stop 1n the claims is lntendedto apply to any suitable mechanism that will perform the required function of the part 1n question.
I believe that I am the first to provide key controlled tabulating mechanism which can be positioned for arresting the carriage at any predetermined denominational position in any predetermined columnar field at one operation; that I am the first to provide a single tabulating mechanism operable for arresting the carriage at any desired denominational position in any desired columnar field; that I am the first to provide tabulating mechanism which by a single operation can be positioned to arrest the carnage at any letter space position in its travel, and that I am the first to provide two coperating tabulating stops and associated tabulatin mechanism for accomplishing any and alI of the results pointed out above; that I am the first to provide a single key controlled stop movable to di'erent distances to determine not only the position of arrest of the carriage in any desired columnar position but also the denominational position of arrest and I wish to be understood as claiming all of such features broadly.
From the foregoing description it Will be seen that I have provided a simple, cheap and efiicient tabulating mechanism which is in the nature of an attachment that can be applied to existing forms of typewriting machines Without changing the struct-ural features of said machines; that the tabulator may be applied to the front of the machine Where it 1s easily accessible to the operator, and, nevertheless, does not interfere with the o eration of other parts of the machine; t at it is unnecessary to detach any of the column stop or other parts of the tabula'tor in order to effect an adjustment of the parts for tabulating work; that the 'tabulator may be quickly and accurately operated by a single movement of a single key in one direction to determine the position of arrest of the carriage at any denomina'tional position within any columnar field and that the carriage by a single movement passes to and is arrested in such position.
This application is a division of my application, Serial No. 252,216 filed March 27th, 1905. I have elected to present broad claims herein covering the structures disclosed in both applications, Whereas the claims in the original case are restricted 'to features notshown herein.
