UNITED STATES PATENT OFFICE GEORGE H. SMITH, OF NUTLEY, NEV JERSEY, ASSIGNOR TO UNION TYPEWRITER COM- PANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

TYPE-WRITING- IVIAGHINE.

To all whom "it may concern:

Be it known that I, GEORGE H. SMITH, citizen of the United States, and resident of Nutley, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Type-writing Machines, of which the following is a specificatlon.

My invention relates to typewriting machines and more particularly to tabulating mechanism.

In tabulating mechanism heretofore employed it has been customary to use a column stop rod or rack with a space or notch for each index on the carriage scale or for each letter space position of the carriage in its line of travel. The column stops were ordinarily adjustable along the column stop bar, being seated in different notches and arranged for cooperation with one or more tabulating stops so that when the carriage was released certain of the tabulating stops would cooperate to arrest it. In the use of such column stops considerable time was required 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.

One of the main objects of the present invention is to overcome these difficulties and to provide comparatively simple and efli cient mechanism for quickly determining the position of the arrest of the carriage and for readily setting the tabulating mechanism accordingly.

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 set forth in the following specification and particularly pointed out in the appended claims.

In the drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a side view, partly in section and with parts broken away, of one form of typewriting machine embodying my invention, sufficient number of parts of the machine being shown to illustrate my invention in its embodiment there. in. Fig. 2 is a transverse sectional view of the same taken on the line am of Fig. 1 and looking in the direction of the arrow at said line. Fig. 3 is a plan view of the ma- Specification of Letters Patent.

chine with parts broken away. Fig. 4: is an enlarged detail diagrammatic side elevation, partly in section, of parts of the tabulating mechanism and the means for setting the stops. Fig. 5 is an enlarged detail perspective view of the column stop bars and some of the associated parts.

I have shown my invention in the present instance embodied in a No. 11 Remington machine which contains a denominational tabulator. It should be understood, however, that the character of the machine and of the tabulating mechanism employed is immaterial so far as, my invention is concerned.

The present invention is in the nature of animprovement upon the construction disclosed in the application of Emanuel Sivertsen and Jens Christian Nielsen, filed April 8th, 1909, Serial No. 488,675.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A carriage t is mounted to travel from side to side of the machine upon anti-friction rollers 5 which are likewise received in fixed grooved guide rails (5 secured to the top plate of the machine. A platen 7 is carried bythe carriage and the type bars 8 are arranged to strike upwardly and rearwardly against the front face of the platen, the type bars being controlled by the usual key actuated means (not shown).

Bracket arms 9 are secured by screws 10 to the carriage and project rearwardly there-- from and support a column stop bar 11. The column stop bar is provided with teeth 12 which project therefrom on opposite sides, forming spaces 13 between the teeth on the upper and lower sides of the bar. Bifurcated plate-like column stops 14L straddle the column stop bar and are received and adapted to slide fore and aft of the machine in the interdental spaces 13 between the teeth on the stop bar. The rear portion 15 which connects the arms of each stop 14 constitutes the contact portion with which the cooperative stops are adapted to engage Each column stop is provided with an upwardly extending projection 16 formed with a vertical face with which a flat sheet metal restoring bar 17 is adapted to cooperate. Inclined cam slots 18 are formed in the restoring bar near the ends thereof and shouldered screws 19 pass through these cam slots and through the spacing washers 20 and engage in tapped openings in the stop bar 11. The restoring bar 17 is arranged parallel with the column stop bar and is mounted to slide endwise and transversely of the stop bar by reason of the inclined cam slots 18 and the screws 19 by which the restoring bar is connected to the column stop bar. A contractile spring 21 is connected at one end to an ear 23 which projects from the restoring bar and is connected at its other end to a pin 24 Which projects upwardly from the column stop bar. A finger piece 25 is formed on the bar 17 to provide means by which it may be moved by hand against the pressure of the spring 21. The position of the bar 17 is such that it is adapted to cooperate with the projections 16 on the column stops, so that when the restoring bar is moved in the direction of the arrow in Fig. 5 said bar is effective to move any of the column stops 14 which may project rearwardly from the column stop bar back to the inoperative position as will hereinafter more clearly appear. Moreover, the position of the bar 17 is such that it cooperates with the projections 16 on the column stops to prevent their removal or accidental detachment from the column stop bar. I'preferably provide as many column stops 14 as there are interdental spaces 13 in the column stop bar. In other words, I preferably provide as many column stops as there are letter space positions in the travel of the carriage, it being understood that adjacent interdental spaces 13 in the column stop bar are situated a letter space distance apart.

A bracket 26 is secured by screws 27 to the top plate of the machine, the bracket having upwardly extending arms 28 provided with bearing openings in which a rock shaft 29 is received. A sleeve 30 is secured by a set screw 31 to the left-hand end of the rock shaft where it project-s beyond the left-hand bracket arm 28. A projecting or selecting device in the nature of a crank arm or finger is formed with a hub 33 which is secured to the rock shaft 29 by a set screw 34, the hub being secured to the right-hand end of the shaft outside of the right-hand bracket arm 28. The hub 33 and the sleeve 30 prevent the longitudinal movement of the rock shaft on the bracket. The free end or contact portion 32 of the arm 32 is off-set to the right to bringit into a position where it will register with one of the column stops 14 at each letter space position of the carriage and preferably where the contact portion 32 is just to the right of the decimal stop 35, as shown in Figs. 2 and 3. The thickness of the contact portion 32 of the finger or arm 32 is such that it will contact with only one of the column stops at a time, the particular column stop with which the finger is adapted to co-act depending on the letter space position of the carriage at the time the finger is actuated. A rearwardly extending crank arm 36 is provided with a hub 37 fixed to the rock shaft 29. The rear end of this crank arm is pivoted at 38 to a downwardly extending link 39 bent at 40 to clear the top plate of the machine and pivoted at its lower end as at 41 to a key lever 42 provided with a finger key 43 arranged in the keyboard of the machine. The key lever 42 is fulcrumed 'on the usual fulcrum plate 44 and is provided with a restoring spring 45. The key 43 is a special key which may be referred to as a selecting key and the only purpose of which is to actuate the link 39, and through this link the crank arm 36 and rock shaft 29 and thus control the movement of the finger 32. A depression upon the key 43 is effective to rock the shaft 29 and thus effect a rearward movement of the selecting arm or device 32 to bring it into contact with one of the column stops 14 and force the latter rearwardly in its spaces in the column stop bar in order to move the column stop to operative position, or to a position where it is adapted to cooperate with one of the denominational or cooperative tabulator or denominational stops or 46 when any of them is moved forwardly by the keys which control them. The various denominational stops 35 or 46 are formed as parts of stop levers 47 pivoted at 48 in a tabulator frame 49 secured by screws 50 to the frame of the machine. The lower ends of the stop levers are pivotally connected to links 51 which in turn are connected at their forward ends to angular levers 52 pivoted upon a rod 53 secured to the frame of the machine. Key stems 54 cooperate with the forwardly projecting arms of the angular levers 52 to actuate them and the stop levers controlled thereby, to move the denominational stops forward into the path of such of the column stops as may have been moved rearwardly to operative position. The key stems 54 are provided with the usual tabulator keys Contractile springs 56 are connected to the angular levers and to a guide plate 57 to restore the angular levers, tabulator keys, stop levers and denominational stops to normal position. The key stems 54 are guided in suitable guide plates 57.

I preferably locate the selecting key 43 in the keyboard of the machine to the left. of the denominational keys 55, as indicated in Fig. 3.

In the use of the devices it may be as sumed, for instance, that a letter is to be written in which vertical rows of names or items and amounts are to appear, which items and amounts in different lines are to be placed exactly under each other. The carriage is moved to the position where the first letter of the first name or item is to be on the carriage scale 59.

written. This may be assumed to be at 15 which is indicated by the pointer 58 The selecting key 43 is then depressed and this effects a rear ward movement of the finger projecting or selecting device 32 and eifects a rearward movement of the cooperative column stop which is opposite the contact portion 32 of the column selecting finger. The said column stop is thereby moved into operative position where it is retained by frictional engagement with the teeth of the column stop bar until replaced or restored to inoperative position. Thereafter, and during the tabulating operation, the projected column stop will co-act with the decimal stop 35 at the same point, 15, in thetravel of the carriage where the carriage was arrested to select the column stop, and in the desired position where the first name or item to be written is to be started. If the operator desires to set the next column stop to write, for instance, an amount in the same line so that the decimal point will be at, say, 55 on the carriage scale, it is only necessary to press down the selecting key 43 when the carriage is moved to a position where the decimal point may be written in a position which corresponds to 55 on the carriage scale. This projects a column stop at 55 to arrest the carriage at such position when the decimal key is depressed. If in the next and subsequent lines a name or item and an amount are to be written exactly under the first ones no further setting of the stops is required and only those column stops are effective which have been moved to operative position by the actuation of the selecting key 13 in the manner described. WVhen the tabulator is to be set for a different character of work, requiring the use of different column stops, those formerly in use may be cleared or simultaneously moved to inoperative position by simply moving the finger piece 25 to the left. This is effective to produce a movement of the bar 17 to the left and forwardly against the pressure of the spring 21, the bar 17 being in engagement with the projections 16 on the operative column stops 1 1 will simultaneously move all of the operative stops forwardly to inoperative position. \Vhen pressure is released upon the finger piece 25 it will be restored to normal position by its spring 21. New column stops may then be individually and successively selected and set in the manner hereinbefore pointed out.

It will be understood that a material advantage of the invention is that column stops are by pressure on the selecting key 43 individually set up while writing the first line so as to avoid calculating beforehand the positions where the stops are to be set, the position of the carriage in the present Structure aiding in deterl'nining the selection of the column stop to be used for that particular point of arrest.

I11 accordance with the present invention I prefer to employ a stop for each index on the scale or for each letter space position of the carriage or, at any rate, for each indeX on the carriage scale or each letter space position of the carriage where ordinarily such stops might be employed, and to provide means whereby each of said stops can be thrown into and out of cooperative position.
