Specification of Letters Patent.

Application filed June 8, 1910. Serial No. 565,846.

new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates to t-ypeWrit-ing machines and more particularly to tabulating mechanism. r

In tabulating mechanism heretofore employed it has been customary to use column stops adjustable along the column stop bar 1 'instance embodied in a No. 11 Remington to different positions corresponding to each index on the carriage scale, or to each letter space position of the carriage in its line' of travel. In the use of such column stops considerable time wasrequired-to set them or adjust them when a change from one character of work to another was made, and the Work involved in determining Where to set the stops was somewhat troublesome.

"bling the parts.

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 hereinafter described and particularly pointed out in the appended claims,

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a fragmentary side elevation with parts in section of one form ofjtypewriting machine. embodying my invention, only a sufficient number of parts of the machine'being shown to illustrate my invention in its embodiment therein. Fig. 2 is an enlarged detail transverse sectional view showing )arts of the .tabulator and resetting mecianism; the

parts being shown in their normal positions.

Fig. 3 s a view corresponding to Fig. 2, but

showing a column stop in its projected or operative position, and the resetting cam moved to operative position to reset the column stop. Fig. 4 is a detail perspective view of the actuating member for the re setting cam. Fig. 5 is a detail perspective view of the resetting cam. Fig. 6 is an enlarged, detail, fragmentary, plan view of 'theparts shown in Fig. 2, together with the selecting device. Fig. 7 is an enlarged, detail, fragmentary, front view of some of the parts represented in Fig. 6.

I have shown my invention in the present anism is in the nature of an improvement of the constructions disclosed in the applications of George F. Ballou, Serial No. 541,995, filed February 4th, 1910 and Clio B. Yaw, filed May 31st, 1910, Serial No. 564,227. The column stop construction and the means for retainingthe stops against accidental displacement are in the'nature o5 improvements upon thestructure disclose in the application of George H. Smith, Serial No. 533,717, filed December 17th, 1909. The frame 1 ofthe machine supportsa carriage '2 which is'adapted to travel-over the top plate from side to side of the machine. The carriage may support the usual cylindrical platen 3, and may be provided with a carriage scale with which a fixed pointer a cooperates. Projecting rearwardly from the carriage are arms 5 to wlnch are 'fixed a toothed column stop bar'6, the teeth 6. (Fig. 2) being arranged on the upper and lower' sides of the bar and forming =interdental spaces in which bifurcated flat sheet metal column stops 7 are adapted to slide Patented Oct. 4, 1910.

' the present invention are the same as those fore and aft of the machine.- These column stops, as best shown in Fig. 2, straddle the column stop bar and the rear end portion 8, which unites the arms of the stop, constitutes the contact portion thereof for cooperation with suitable tabulator stops as will hereinafter more clearly appear. Each of the column stops 7 is provided with an inwardly extending or de ending contact piece or projection 9 a apted to slide through one of the interdental spaces in the stop .rod, when the stop is placed in position on the stop rod. A bar 10 is detachably secured by screws 11 to the front face of the column stop bar. This bar 10. is of sufiicient width to close the forward ends of the interdentalspaces between the teeth 6 at the upper side of the column stop bar, so as to form an abutment or contact for the projections 9, to limit the rearward movement of the column stops on the bar 6, and thus prevent their removal from the stop bar except when the bar 10 is detached. Each of the column stops is provided with a substantially U-shaped spring 12, coiinected at one endby rivets 13 to a side of the associated stop. The free end of the sprin is provided with an enlargement 14, adapted to bear with a spring pressure against the crown of one of the adjacent teeth 6 on the column stop bar, whether the column stop he in the retracted or inoperative position shown in Fig. 2, or in the projected or operative position shown in Fig. 3; and to exert sufiicient pressure to maintain the associated stop against accidental displacement from either of these positions. It should be understood that the column stop bai'preferably extends throughout the length of the carriage and is provided with as many pairs of inte'rdental spaces between the teeth 6* as there are letter space positions of the carriage in the travel thereof from side to side of the machine, or as there are indices on the carriagescale. Preferably a column stop 7 is provided for each set of oppositely dis posed interdental spaces, so that there are preferably as many column stops as there are letter space positions of the carriage.

In the present instance I have shown a series of denominational stops 15, cooperative with the column stops. The tabulator mechanism which cooperates with the column stops shown in the resent instance is I similar to that employed 1n the No. 11 Remframe 18, secured by screws 19 and 20 it" ington machine, but for the purpose of my presentinvention it will be understood that any suitable tabulati'ng mechanism may be employed in connection with the column stops. The denominational stops 15 are formed as parts of upright denominational stop levers 16, pivoted at 17 in a tabulator the main frame of the machine. The lower ends of the sto levers 3% re pivotally connected to pus links 21, which are"connected at their forward ends to depending connected at one end to the depending arm of the angular lever 22, and at its opposite end to the plate 24, so as to restore the tabulator key 26' and the parts controlled. thereby to operative position. It will be understood that when any of the column stops ismoved rearwardly on the column stop bar to operative position, it is in a position to cooperate with one of the denominational stops 15, when the latter is projected forwardly by the depression of the corresponding tabulator key 26.

In order to project the desired column stops to operative position, I have provided projecting means which is coiiperative with the column stops independently,- or individually, to move any desired one of them' ata time to operative position; the particular stop'which may be projected to operative position depending on the position of the carriage in its line of travel. Thus I have provided an actuating arm, finger, or selecting device 28' formedasan upwardly extending crank arm, which projects from a hub 29 (see Fig. 6),secured to a rock shaft 30,- mounted to turn in bearings in a bracket 31, secured to the top plate of the machine. From an inspection of Fig. 6. it

will be seen that the arm 28 is bent to the right, so as to bring the free end portion thereof just to the right of the left-hand, or

This arm 28 extends forwardly of thecolumn stop bar 14 and forwardly of the column stops carried thereby, and at each letter space movement ofthe carriage a column stop is brought into register with the contact portion of the setting or actuating arm 28. The rock shaft30 likewise. has a Iea-rwardly extending" crank arm 32 projecting'therefromQ A ink 33 is ivoted to this arm and extends downward y, .and is pivotally connected at its lower end, as at 34, to a key lever 35, fulcrumed on a plate 36 secured to the base of the machine. A selecting or projectingkey 37 is carried by the key. lever and is preferably located in the keyboard of the machine, and by which control of the selecting device 28 is alforded. A restoring spring 38 is connected at one end of the key lever 35, and at its opposite end to a fixed plate or finger39. The restoringspring s elfective to move the key {ever 35 and the parts controlled thereby 971.,ees

v turned, and .the actuating device 28 is moved rcarwardly to'engagc one of the column stops and move it to operative position.

In order to quickly restore all of the column stops to inoperative position, or to move them forwardly .on the column stop bar, I have provided a resetting device,

' wiper, or cam designated as a whole by the reference numeral 40, and shown in detail in Fig. 5. with inclined faces 41 on the right and lefthand sides thereof; The member is also provided with a substantially cylindrical bearing portion 42, with a flat face 43 forming one side wall of a cut-out portion 44,

{and with an inclined, cam groove 45. The cyl1ndrical bearing portion of the member 40, is received in a cylindrical bearing opening 4.6 drilled through a casting 47, formed integral with the tabulator frame 18 at the left-hand side thereof. A screw 48 is re ceived in. a tapped opening in the casting,.

and extends at its free end into the cut-out or recess 44, and constitutes a stop to'prevent a withdrawal of the. member 40 from the bearing opening 46 therefor. A cylindrical opening a9 is drilled through thecasting/l'iat right angles to the opening 46..

The opening 49 receives a substantially cylind-rical bearing portion 50, of an actuating device, indicated as a whole by the refercnce numeral 51, and shown in detail in Fig. 4. This actuating devioeis provided with flat faces 52 and 53, which cooperate with flat faces 54' and 55 on the member 40,

to prevent a turning movement of either of the members 40' or 51. A The member 51'is likewise provided with an inclined cam projection 56, whih matches and is adapted to be received in the cam groove 45 in the member 40. A cup-like receptacle 57 is supported on .top of the casting 47; with the bottom' of the cup arranged downwardly, and hav adapted to contact with a circumferential flange 62'on the cup when the finger piece is depressed as shown in Fig. 3. A coiled expansion spring 63 surrounds the stem 58, and bears at "its lower end against the bot tom wall of the cu and at its up er end against the top wal of the finger piece. It will be observed that the cu section 57, and

the cylindrical portion 61 o the finger piece,

constitute a housing which incloses the spring 63, and that this spring is effective to normally maintain the actuating device 51in the elevated position, shown in Fig. 2,

and to maintain the cam. 40 in the with- This cam or wiper is provided.

drawn or inoperative position. When, however, downward pressure is exerted on the finger piece 60, this is effective to depress the actuating member 51, thereby camming the member 40 forward in the general direction of movement of the column stops'out of operative position. I When the member 40 is moved forwardly to operative position, as shown in Fig. 3 and as indicated in dotted lines in Fig. 6, it is in cooperative relation with those of the column stops 7 which have been moved rearwardly on the column stop bar, to operative position. A movement of the carriage in either direction at this time will bring the operative column stops successively into contact with one of the inclined faces 41 on the resetting device'40 and such column stops will be forced forwardly successively to inoperative position, thus clearing the entire set of column stops which may have been moved to operative position.

.From an inspection of Fig. 3 it will be seen that a flat face 64:, on the end of the cam 56, is brought into the path of a corre- Tsponding'flat face 65 on the member 40. when the finger piece 60 reaches the limit of its downward movement. These fiat faces Y64 and 65 are vertically disposed, and constitute a lock to prevent a rearward movement-of the member 40 under the action of the; column stops 7 thereon, as the column stops are being restored to normal or inoperative position. When pressure is released on the finger piece 60, the actuating member 51 moves upwardly carrying the flat face 64 out of engagement with the face 65, and moves the cam. 56 into interlocking-engagement with the cam groove 45 in the member 40. The continued upward movement of the actuating member 51, effects a rearward camming action on the member 40, thus positively withdrawing it, to the position shown in Fig. 2, where it is in the inoperative position or is out of cotiperative relation with the operative column stops.

The rearward movement of the member indicated at a in Fig. 6. The downward movement of the finger piece 60, and the 40, (and the upward movement of the memforward movement of the resetting device 40 as well, is limited by the engagement of the lower end of the linger piece with the flange 62, as hereinbefore indicated.

In assembling the parts of the resetting mechanism, it maybeassumed that all'of the parts are disconnected from the supporting casting 47, and are. disconnected The member 40 is first moved rearwardly in. its bearing opening 46,

one from another.

until the enlarged transverse opening 44,13 brought into register with the vertically'dlsspindle 58.

&

posed bearing opening 49., The member 51 is then introduced upwardly through the bearing opening 49, and the cam 55 is seated in the cotiperating cam groove 45 in the member 40; the two members being manipulated relatively to each other until this interlocking engagement between the cam and cam groove is eifected. The thimble or cupslike section57 is then placed in position with the spring 63 surrounding the he finger piece 60 is then screwed into position. The set screw48 is next threaded into place and the parts are assembled. The purpose of the set screw 48 is to prevent a withdrawal of the member 40, even if the finger piece 60 should be removed from the actuating member 51. In short, the set screw'48, coiiperating as. it does with an end wall 66 of the cut-out 44, constitutes a stop which limits the forward movement of the member 40, to a position where the actuating member 51 cannot be withdrawn from its bearing opening 49, 'on account of the cotiperative engagement between the members 40 and 5l. When, however, the set screw 48 is removed, or the end thereof withdrawn from the opening 44, a further forward movement of the member 40 may be effected, in order to bring the member 51 fully within the enlarged cutout or opening 44, so as to alford a removal of the member 51 through said opening.

In 'order to prevent an undue straining,

,or flexing, of thecolumn stop bar- 6, a supporting bracket 67 is provided. The rear end of this bracket is secured, by screws 68, to the tabulator frame 18,.and the forward end portion of the bracket is bent downwardly at 69, and. rearwardly at 70, to a position where the free end 70 will be received between the bifurcated, arms of the column stops, and where it is adapted-at its free end to just clear the bar. 10, fixed to the column stop bar. During the forward camming movement of the column stops, by the device 40, any undue strain upon the column stop bar will tend to flex it forwardly and this will be resisted by the fixed bracket 67 itbeing observed that the bracket is locatedadjacent to the cam or resetting device 40. This bracket constitutes no part of my present invention but is the invention of George A. Seib.

.In .useit may be assumed,for instance, that a letter or invoice is to be written in which vertical rows of names, or items and amounts are tobe written, which items and 1 amounts in the diiferent lines are to be placed exactly under each other. It is only necessary, when the carriage is moved to the position where the first letter of the name or'i'tem is to be written, as at, say, 15 on the carriage scale, to press down the selecting key 37. This moves the column stop at 15 which is opposite the column selecting finger, into operative position. Thereafter, during the tabulating operation, the projected column stop will co-act with the' decimal stop at the same point, 15, in the travel of the carriage,- where the carriage was arrested to select the column stop, and in the desired position where the name or item is to be started; If the operator desires to set another column stop to write, for lnstance, an amount in the same line at, say, 55 on the carriage scale, it is'only necessary, in a decimal tabulator, to press down the selecting key 37 when the carriage is found to be at the point where the decimal point is to be written at 55 as indicated further setting of the stops is required;'and

only those column stops are effective which have been moved to the "operative position by theactuation of the. selecting key 37 in the manner described. When the tabulator is to be set for a diiferent character of work; requiring the use of different-columnstops, those formerly in use may be cleared, or movedto inoperative position by the cam 0r wiper 40, in the manner hereinbefore described. 7 p
