Application filed January 9, 1900. semi No. 883. (No model.)

To ctZZ whom, it may concern:

Westfield, in the county of Union and State of. New Jersey,- have invented certain new and useful Improvements .in Type Writing Ma chines, of whichthe following is tion.

The present invention relates to tabulating IO devices for type-writing. machines wherein the carriage is released at any point in its forward traverse from the control of its escapement mechanism, is quickly advanced, and is automatically arrestedatagiven point I5 or points or at variable distances therefrom, the primary object of the invention being to provide for-writing from time to time a variety of tabular workwith a'minimnm of adjustments in the machine.

Heretofore machines of the class referred to have been provided with a row or series of. independently adjustable column stops on the carriage and with a series of denomina tion-stops'on the framework independently movable into and out of position for coaction with the said, column-stops. In this prior construction it is necessary after the columns'tops have been set and used for one tabular form to reset many or all of them whenever it is desired to Write upon a tabular form differing from the first,and of course when it is again desired to write upon tabular forms of the first-named kind the column-stops have to be set again.

' According to the present iuvention a number of rows or sets of column-stops is employed, and means are provided for bringing one or another of these sets into position for coaction with the said denomination-stops. 40 Various methods of mounting and moving said sets of stops maybe employed without departing from the scope of my invention but I prefer to arrangethem upon a rotatable rod or bar, the stops for each tabular form ro. 4 5 jecting therefrom in a different direction from the stops for the other form or forms. By

rotating the bar the stop or row of stops for any desired form may be moved to position for coaction with said denomination-stops 50 and the previously-used row of stops simultaneously moved outo'f working position.

a specifica-- embodied. .verse section with parts omitted of the ma- Fig. 3 is a perspec Preferably said column-stops are adjustable along said 'bar or rod. rather than being made *in-tegral therewith or immovably attached thereto, as this adjustability provides for the writing of an indefinite number of different tabular forms. By preference the rod or bar is polygonal and is provided with notches or teeth on two or more sides thereof, and the column-stops may be provided with springy forks to engage with teeth on two opposite sides of the bar.

' To these ends the invention consists of certain features of construction and combinations of devices hereinafter described, and moreparticularly pointed outin the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, forming part of this specification, in which- :Figure 1 is a plan view, partly brokenaway and with certain parts omitted, of a typewriting machine in which the invention is Fig. 2 is'a central vertical transchine shown in Fig. 1. tive view of a revoluble rod or bar shown in Figs. 1 and 2 and having rows of columnstops or tappets projecting therefrom in different directions. Fig. 4 is a longitudinal sectional view of the rod shown in Fig. 3, the central part of the rod being omitted, showing the method of mounting said rod for rotation. Fig. 5 is a perspective view of a journal for the rod shown in Fig. 3, said journal being partly cut away or slabbed off, so as to form two opposite parallel flat sides thereon. Fig. 6 is a transverse section of the rod shown in Figs. 3 and 4, the section being taken through a journal at its flattened sides. Fig. 7 is a View showing a column-stop in side elevation audits. carrier in cross-section. view showing two column-stops integral with each other and projecting in difierent directions from a common carrier or support. Fig. 9 is a view showing three integral columnstops projecting in different directions from Fig. Sis a column-stop and a multiple column-stop in side elevation and also a cross-section of the carrier shown in Fig. 11. Fig. 13 is a perspective view of a journal for the revoluble stop-carrier when said carrier is provided with more than two longitudinal rows of column-stops or when the stops thereon project therefrom at right angles to each other.

The same numeral of reference will be used to designate the same part throughout the drawings.

1 is the base-frame of the Remington No. 6 type-writing machine.

2 represents standards rising from the base 1; 3, a top plate or type-ring attached to the standards 2; 4, type-bars connected with the type-ring 3, as usual; 5, key-levers with which the type-bars 4 are connected by rods or connections 6; 7, a carriage to which a letterspacing rack 8 is connected by pivoted arms; 9, a pinion meshing with the rack S; 10, an escapement-wheel suitably connected to the pinion 9; 11, escapement-dogs coacting with the wheel 10 to control the letter-space movement of the carriage 7; 12, a platen connected to the carriage 7, so as to move therewith.

13 represents arms secured to the frame of the carriage 7 by hooks 14 and screws 15 16. The screws 15 pass above the transverse bar of the carriage 7 and engage or bear against the sockets 17 of the usual removable papershelf, (not shown,) and the screws 16 engage beneath the said transverse bar of the carriage 7 and abut against a vertical part thereof. The arms 13 extend rearwardly and are curved downwardly from the carriage 7 to about a horizontal plane through the shaft of the pinion 9. At their rear ends the arms 13 are provided with transverse slots 18. To each arm 13 an elongated journal-block 19 is attached by means of a screw 20, which passes through and is adjustable along the said slot 18 and engages with a threaded hole 21 in the said block. The blocks 19 extend horizontally toward each other, or in the direction of motion of the carriage, and each is fitted or provided with a cylindrical journal piece or stud 22, which is preferably made separately and forced into a bore in the said block, although obviously the block and journal may be made in one piece, if desired.

Extending between the inner ends of the blocks 19 and abutting against cylindrical shoulders or bosses formed thereon is .a bar or rod 23, preferably polygonal in cross-see tion (shown as square in the drawings) and journaled on the said studs 22. Each stud or journal 22 is slabbed off at 2a upon opposite sides thereof. Holding-pins 25, secured to springs 25, the latter being fastened by screws 26 to the bar, are secured to each end portion of the rod 23 and pass through radial perforations 25 in the rod 23 and bear against the flattened parts 21 of the studs 22. By the application of force to the rod 23 the same may be turned, the spring-pins 25 yielding, as indicated in Fig. 6, to permit the rod to turn and then engaging the opposite fiat surface 24 to hold the rod. The rod shown at Fig. 3 is provided with transverse notches, recesses, or kerfs 27 upon two sides thereof, forming rectangular teeth 27 at letter-space intervals. The rod may be provided upon one or both plain sides with a scale or scales 28, corresponding in its markings to the usual carriage and platen scales and also to the teeth 27 or notches 27*.

The column stops or tappets comprise metal plates of a thickness to fit closely in the kerfs 27, being forked for the purpose of engaging with the said rod or tappet-carrier 23 at opposite sides thereof. The form of columnstop shown in Fig. 7 comprises acarriage-arresting portion 29 and two parallel arms 30, separated by a distance equal to or slightly greater than the distance separating the bottoms of opposite kerfs in the rod 23, it being understood that the teeth 27 at opposite sides of the rod 23 are in line or squarely opposite each other. In order to prevent accidental displacement of the column-stop from the rod 23, one of the arms 30 is formed or provided with a beveled projection or hooked portion 31, which extends inwardly and engages with an edge at the bottom ofa kerf, as indicated in Fig. 7, the inherent springiness of the metal of the column-stop sufficing to permit of the placing of the column-stop in position on the rod 23 and then to cause the tooth 31 to hold it in place with sufficient force to prevent accidental movement thereof. The forked column-stops are, however, readily removable from the rod 23 and may be inserted between pairs of opposite teeth atany point on the rod, thus providing for their adjustment to form stops for different kinds of tabular work.

The column-stops shown in Fig. 7 may be placed upon the rod 23 from either side thereof, as indicated in Fig. 3, the latter figure showing two longitudinal rows or series of stops upon the rod. All of the stops move simultaneously with the rod when it is rotated or revolved for the purpose of moving either row into or out of working position. In order to provide for the contingency in which difierent tabular forms may have one or more columns or ruled lines falling upon or beginning at the same division of the type-writer scale, some of the adjustable column-stops may have their working arms or teeth oifset by a letterspace distance, so that when one of these offset stops and one not offset are placed in adjacent kerfs upon the rod 23 their working faces will lie in the same vertical plane and will arrest the carriage in the same position, whichever stop may have been turned to working position. Such offsets are indicated at 32 in Fig. 3.

The devicesshown in the drawings for coaction with the column stops or tappets 29 in arresting the carriage at variable distances from points predetermined by adjustment of the tappet along or upon the rod comprise a series of denomination-stops, preferably in the form of independently-movable blades 33, operating-levers 34 therefor, key-actuated horizontal push-rods 35, and certain accessories. The denomination-stops 33 are preferably in the form of metal plates arranged on edge and side by side in rear of the rod 23. They have independent sliding or plunging motion forward and back between parallel vertical jaws or guides 36, which are united by a horizontal cross-head 37 of a frame 38.-

' or top plate 3 by means of horizontal stayrods 42, which pass through ears 43 on the frame 38 and are firmly and adjustably attached thereto by means of nuts 44, workingon the threaded ends of the stay-rods 42. At

their front ends the stay-rods 42 are provided with jaws 45, which hook under the rear flange of the top plate 3, said flange being clamped between the said jaws 45 and screws 46. Each denomination-stop 33 is formed with alug 47 upon the upper edge thereof and also with a longitudinal slot 48. A lateral pin 49 is formed or provided in a recess 49, formed upon one side of each stop 33, the end of the pin being flushed with the side of the stop. Transverse guide and supporting rods 50 extend through the slots 48 and are supported at their ends in the jaws 36. Any desired number of loose rings or rolls 50" may be placed along said rods 50. Each lever 34 is formed with an open slot 34 at its upper end for engagement with the pin 49 of the corresponding stop 33, the end of the lever 34 being of such a thickness as will enable it to lie in the recess 49. The levers' 34 are pivoted intermediate their ends upon a transverse rod 51, which is secured in the frame 38. At

their lower ends the levers 34 are reduced inwidth and pass through eyes formed in the ends of horizontal slide-rods 35. The sliderods 35, which underlie the stop-operating levers 34, are guidedat their rear ends in holes formed in a cross-bar 52 of the frame 38 and at their front ends in holes formed in a crossbar 53, which is clamped to the front flange of the base-frame 1 by jaws and screws 54. At their front ends the push-rods 35 are provided with finger keys or buttons 55, which may be suitably marked to represent various denominations or orders. Each rod 35 has a collar 56 adjustably secured thereto by a setscrew 57. A coiled draw-spring 58 is attached at one end to each collar 56, as by the screw 57. The other end of each spring is attached to the front bar 53, as by screws 59, the said springs being-tensioned to draw the pushrods 35 forwardly of the machine, so as to cause the levers 34 to holdthe denominationstops 33 rearwardly and out of the path of the tappets 29. I

The carriage may be released in any suitable manner from the control of the escapement-dogs 11 to permit it to run forward freely under the influence of its spring-drum 60, which is, as usual, connected to the carriage by a strap 61. The device shown for this purpose comprises a horizontal transverse universal bar 62, arranged in front of the lugs 47 of the denomination-stops 33 and provided with vertical arms 63, which fork the jaws 36 and are pivoted at 64 to the frame 38. One of the arms 63 is in the form of a bell-lever and extends forwardly, as indicated in Fig. 2. Said forward arm of the bell-lever is connected by a vertical link 65 with a crank-arm 66 on a forwardly-extending horizontal shaft 67, which is provided with a returning-spring 67 and is journaled in lugs 68 of a'frame'69, the latter being attached to the top plate 3 by. a screw 70. Atits front end the shaft 67 is provided with a bent horizontal crank-arm '71,

upon the free end of which is mounted a 29 is first arranged upon one side of the rod 23v so that each stop will be opposite that gradnation or scale-mark upon said rod which corresponds with the scale-mark upon the platen-scale opposite which it is desired to print the decimal-point in or where it is desired to begin writing words. Then by operating' that one of thedenomination-keys 55 which corresponds to the highest order in the number to be written the corresponding rod 35 is pushed rearwardly and the corresponding lever 34 is rocked to move the corresponding denomination-stop 33 forwardly into the path of the tappets 29 at the rear of the rod 23. In its forward motion the stop 33 causes the universal bar 62 to move forwardly, thus vibrating downwardly the horizontally-extending arm 63 and pulling down the connecting-rod 65 and the crank-arm 66,

thereby causing the shaft 67 to rock and raise the crank-arm 71 and roller 72, which last contacts with the rack 8 and lifts it out of mesh with the pinion 9, thus freeing the carriage and permitting it to run forward under the influence of its spring-drum until the first rear tappet 29 at the right of the forwardlyprojected stop 33 is brought against the said projected stop, thus arresting the carriage. Upon release of the key 55 the connected spring 58 draws the rod 35 forwardly, thus vibrating the lever 34 and moving the projected denomination-stop rearwardly to normal position and out of the path of the working tappets. Simultaneously the Weight of the rack 8 or the usual spring} bearing thereon (not shown) carries the rack downwardly and into mesh with the pinion 9, the universal bar 62 and parts operated thereby being caused to return to normal position by the tension of the spring 67 on said shaft 67, the latter moving as fast as the connections between it and the lug 4.7 of the projected stop will permit. The platen 12 is now in position such that the number may be written thereon in proper relation to the decimalpoint, it being understood, of course, that the left-hand slide or stop 33 in Fig. 1 corresponds to the decimal-point and that the stops at the right thereof correspond, respectively, to units, tens, hundreds, &c., in the order named. The front ends of these stops are beveled at the left-hand sides, and the tappets 29 are tapered rearwardly, so as to prevent the latter from blocking the former in their forward movements. After writing the desired number the denomination-key 55 corresponding to the highest order in the next number to be written is operated and the carriage again positioned. After writing the second number a key 55 is operated for positioning the carriage so that the third number can be written, and so on to the end of the line of writing. The carriage is then returned to begin a new line and the successive operations repeated. When it is desired to do a different class of tabular work upon the machine, it is unnecessary to disturb in any way the relative individual arrangement of the column-stops that are already set. Instead of doing so the rod 23 is turned in its bearings, so as to bodily remove the previously-used set of tappets from working position and simultaneously bring another face of the bar 23 opposite the denomination-blades 33. A fresh set of tappets may be then adjusted along said face of the bar, using either plain or offset tappets, or both, as may be found necessary or desirable. The writing of the tabular form may then proceed as usual. The machine being now provided with two sets of difierently-arranged tappets, either of which sets may be brought independently to working position when required, it follows that either class of tabular forms may be written at any time and from time to time without the necessity of disturbing the tappets in either set--that is, without the necessity of disturbing the arrangement of tappets one to another used in one kind of tabular work in order to do some other kind of tabular work. It will further be observed that a third and a fourth set of tappets may likewise be arranged upon a single bar, so that the machine may be provided at one time with means for writing four different kinds of tabular forms, which it is believed will sufiice for ordinary purposes.

Of course instead of arranging the tappets or column-stops in sets in the manner above described the several sets may be arranged in proper order on the several sides of the bar before the commencement of any writing at all.

In the construction illustrated at Fig. 8 two column-stops 29 and 29 are formed integrally with each other and come opposite adjoining faces of the rod 23. This construction may be termed a multiple tappet or multiple column-stop and may be employed in connection with single or other differently-formed stops, so that the rows of stops at the diderent sides of the bar or carrier may be differently disposed for different pieces of work.

In the construction illustrated at Figs. 9 and 10 the three teeth 29, 29, and 29" of the multiple tappet are formed integrally and project from three faces of the rod 23. The teeth 29 and 29 are offset at 32, one to the right and the other to the left, for purposes hereinbefore set forth.

In the constructions illustrated in Figs. 11, 12, and 13 teeth 27 are out upon all four sides of rod 23, so that tappets may be placed thereon in a great variety of Ways. The journals 22 are slabbed off on four sides at 24 to provide four bearings for the pins 25. (See Fig. 13

1 mm the foregoing description it will be seen that a plurality of sets of column-stops is combined with a set of denomination-stops, the latter being adapted to cooperate at will with any of the column-stops, and that in carrying out the invention provision is made for moving any set of column-stops into 00- operative relation with the denominationstops and for withdrawing them at will.

By means of the slot 18 and the screw 20 the stop-carrying rod 23 may be adjusted in the direction of the escapement movements of the carriage, so that any tappet arranged upon said rod may have the desired relation to the blades 33, it being customary in tabulating mechanisms to arrest the carriage about midway between two consecutive letter-space positions thereof, so that upon releasing the carriage from the control of the tabulating devices it may have a slight advance movement or drop before being arrested by its escapement devices, whereby a correct positioning of the carriage by the tabulating mechanism is insured. The column-sto'ps may be withdrawn simultaneously from cooperation with the denominationstops without disturbing said adjustment at 18.

While I have illustrated and described the preferred form of the invention, I do not limit myself to the specific forms of column-stops or column-stop carrier shown nor to the specific method set forth of moving the carrier to bring the different sets of column-stops into working position, since in so far as the broad invention is concerned other means or methods of mounting the column-stops may be adopted without departing from the scope of my invention. stops may be otherwise moved for securing ooaction between the desired row of columnstops and the denomination-stops 33; nor is it essential to my invention that the carrier 23 should be so located as that the tappets should project horizontally when in working position.

While I have shown and described a pluralityof sets of column-stops as arranged at one time in the machine and as having a common support, yet the invention is not limited to this arrangement, inasmuch as it is broadly new to adapt a plurality of sets of column-.

stops to be used at different times as occasion may arise in the tabulating mechanism of a type-writing machine without the necessity of disturbing the relative arrangement of the stops in any set at any time, and so long as suitable provision is made for enabling this to be done by mere manipulation of the parts and without the employment of mechanical skill it is not essential that all the column-stops in all of the sets be carried upon the machine at one time.
