TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,317, dated March '7, 1905.

Application flied March 10, 1902. Serial No. 97,493.

To (all 11:70am it may concern:

Be it known that I, CARL GABRIELsoN, acitizen of the United States, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is aspecification.

. My invention relates to tabulating mechan isms for type-writing machines, and has for its main object to provide a novel and efficient tabulating mechanism and one wherein the actuation of a key will effect the release of the carriage and will interpose a tabulating-stop in its path of movement,so as to arrest it at the desired point for column or, tabulating work.

To the above and other ends, which will hereinafter appear, my invention consists in the construction and arrangement and combinations of parts to be hereinafter described,

and particularly pointed out in the appendedclaims.

In the accompanyingdrawings, wherein like reference-numerals designate corresponding parts in the various views, Figure 1 is a central vertical sectional view of one form of machine embodying my invention, the section being taken from front to rear of the machine. Fig. 2 is a rear elevation'of the machine with certain parts broken away and others omitted. Fig. 3 is a partial plan view of the rear portion of the machine. Fig. at is a fragmentary plan view, partly in section, of a portion of the tabulating mechanism at one side of the machine. Fig. 5 is a detail perspective view of a portion of the tabulating mechanism. Fig. 6 is an enlarged detail fragmentary plan view, partly in section, of a portion of the tabulator mechanism. Fig. 'Tis an enlarged detail transverse sectional view through the rock-shaft, the view illustrating a tabulating-stop in place thereon. Fig. 8 is an enlarged detail bottom view of one of the tabulating-stops with the spring removed. Fig. 9 is adetail plan view of the spring empioyed on each of said stops. Fig. 10 is a detail side view of the tabulatingstop which is carried by the carriage, together with a cooperating tabulating-stop on the rockshaftor stop-bar, the latter being shown in two positions, one in dotted lines. Fig. 11 is adetail rear elevation of the tabulating-stop on the carriage, together with a portion of the earriage to which said tabulating-stop is connected. Fig. 12 is a fragmentary plan view of part of the carriage-feed mechanism and of a portion of the carriage-releasing device which is connected to the tabulating mechanism. Fig. 13 is an enlarged detail perspective view of one of the supporting-brackets of the paper-carriage and tabulator rock-shaft.

In the various views parts have been omitted or broken away to more clearly illustrate other features of the machine.

The tabulating mechanism has been illustrated as applied to a front-strike machine, though obviously it may be applied to other descriptions of type-writing machines.

Referring particularly to Fig. 1 of thedrawings, it will be seen that 1 represents the keylevers, pivoted or fuleru med at 2 in the base of the machine, and from the latter rise posts 3, which support a top plate 4. Each key-lever 1 is restored to the normal position by a spring 1 and is provided with a linger-key 5. oted to each key-lever at 6 is a bell-crank or actuating lever 7, which is slotted at its lower end to engage a fulcrum-bar or abutment 9, that extends transversely of the machine. Pivoted to the upper end of each bell-crank 7 at 10 is a link 11, which at its forward end is pivoted at 12 to a type-bar 13, which is pivoted upon a fulcrum-wire or curved rod 14, seated in the groove of a segment 15, and which is formed with radial slots 16 for the type-bars.

Extending-transversely beneath the various key-levers l is a universal bar 17, which is connected at its ends to links 18, the upper ends of which engage a transverse bar 19, secured to an arm 20, that projects from a rockshaft 21, from which extends upwardly a dogrocker 22, that carries the usual or any desired feed dogs 23. The rock shaft is provided with the usual restoring-spring 2% for returning the parts to the normal position. The feed dogs cooperate with a feed wheel 26, Fig. 12, by pawl-and-ratchet mechanism '(not shown) similar to that employed in the No. 6 Remington machine, and by means of which the carriage and feed-wheel move in unison when the escapement mechanism is actuated and the carriage is moved from right to left and whereby when the carriage is moved from left to right the feed-wheel will remain fixed against movement and in engagement with one of the feed-dogs. The shaft 26, to which the feed or escapement wheel is operatively connected, carries a feed-pinion 27 at its forward end, which pinion meshes with a rack 28, .that is connected to arms 29, each secured to ashort rock-shaft 30,that turns in a bearing 31 in the platen-frame 32, springs 28 tending to maintain the rack in engagement with the pinion. To the outer end 34 of each rock-shaft 30 is attached an arm or lever 33, which is provided at its forward end with a key or finger-piece 35, the depression of which is effective to swing the rack 28 out of engagement with the feed-pinion, when the carriage is free to be propelled in the direction of its feed or from right to left by a carriage spring-drum 36, that turns on a spindle 37, which projects from a bracket 38, secured to the top plate 4, and which bracket likewise constitutes a support for the rockshaft or axis 21 of the dog-rocker. A driving band or strap 39 is connected at one end, 40, to the spring-drum and at its opposite end at 41 to an arm extending down from the right-hand end of the carriage. The rear upright portion of the carriage is longitudinally grooved on opposite sides, as at 42, for the reception of antifriction-balls 43, and cooperating therewith are longitudinally-grooved rails 44 and 45, which are secured by screws 46 to brackets 47,.mounted on the top plate 4. A platen 48 is mounted in the carriage 32 forward of the ball-bearing supports therefor.

At one side of the keyboard is situated a tabulating-key 49, which is carried by a keyl ever 50, that is pivoted at 51 to a bracket secured to the bed or frame of the machine and is returned to the normal position by a coiled spring 52, that bears at one end, 53, against the frame and at its opposite end, 54, against a tail or extension of the key-lever 50, having astud 55, which projects into the spring. The key-lever 50 carries a laterally-projecting pin 56, which extends into a slot 57, formed in the upwardly-extending projection 58 of a sublever 59, that is pivoted at 60 to adepending bracket 61, secured to the frame of the machine. Spacing washers or tubes 61 surround the pivot-pin 60 between the lever 59 and the bracket 61 on one side and the lever 59 and the side plate of the base-plate on the other side, and thereby maintain the lever and its connected parts in proper working positions. The rear end of the sublever 59 carries a laterally-projecting pin 62, which extends through an opening in the lower end of an actuating-link 63, the link being retained seated on the pivot-pin 62- by a leafspring 64, which is secured at 65 to the sub lever and bears at its free end against the free end of the pin. The actuating-link extends upwardly from the sublever through an opening in the top plate, and the upper end of the link is screw-threaded and takes into a threaded opening in a connecting-piece 66, which is pivoted at 67 to a crank-arm 68, which is secured by a screw 69 to a rock-shaft or oscillatory stop-rod 70. A spring 63 surrounds the link 63 and bears at one end against the top plate and at the opposite end against the part 66 and tends to restore the link and the parts connected thereto to the normal position. The stop-rod or rock'shaft 70 extends in the direction of the travel of the carriage and is supported in place in the brackets 47, hereinbefore referred to. Upon reference to Fig. 6 it will be observed that one end of the stop-bar or rock-shaft is reduced .to provide a cylindrical journal 71, which is received within a central opening in a collar 72, which is provided with external serewthreads 73, that cooperate with screw-threads 73 in the associated bracket 47. The outer end of the collar 72 may be provided with a knurled head 74, by means of which the collar may be adjusted in its bracket 47 to afford an endwise adjustment of the rod 70, which .is seated loosely in the other bracket at its opposite end. The outer face of this sleeve is likewise recessed for the reception of the head 75 of a screw, the shank 76 of which takes into a threaded opening in, one end of the stop-bar or rock-shaft 70. The head 75 of the screw thus bears upon an internal shoulder 7 5 on the sleeve, whereas the inner end of the sleeve bears upon a shoulder 71 formed by the reduced portion 71 of the rod, so that the rod is prevented from moving longitudinally in its bearings. When the rod or shaft 7 O is turned, the screw 75 76 at the end thereof turns with-the shaft. This stop-bar may have a scale on the upper face thereof, as shown in Fig. 3, the graduations of the scale corresponding to the carriage-scale, the marginscale, or the letter-spacing capacity of the carriage, and each side of the bar is serrated, as shown at 77, for the reception of the flanges or forks 78, provided on the tabulating-stop device. Each of these stop devices comprises a segmental device or housing 79, which is provided on its outer face with a lug or stop projection 80. Contained within the segmental portion or housing 79 of each stop is a segmental clamping spring, which is secured thereto at 82 and is adapted to bear upon and partly surround the cylindrical portion of the stop-rod when the stop device is in place thereon, as indicated in Fig. 7, thus clamping the stopin place. It will be understood that the serrations on the stop-rod correspond in their spacing to the letter-space distances which the carriage is adapted to travel. in order to adjust one of the tabulating-stops from one point on the rod to another, it is merely necessary to pull the stop upwardly, thus movingthe flanges or forks 78 thereof out of the notches or kerfs in the rod against the clamping or gripping tension of the spring 81, which normally prevents accidental detachment of the stop from the rod. From an examination of Fig. 7 it will be seen thatthe forks 78 hear at their inner edges 83 against cooperating flattened portions of the rod at the bases of the kerfs and that the free ends of the C-shaped spring bear on the rod considerably below the center-thereof, so that the stop is thus locked to rotate with the rod when it is turned in its bearings. In putting on the stop the free ends of the spring are at first expanded as they ride down over the cylindrical portion of the rod, while the forks are entering the kerfs in the latter; but after the ends of the spring have passed by the middle of the rod they automatically contract and grip the rod on its underside andin a way such as firmly to hold the stop against casual displacement.

From the foregoing description it will be understood that the stop device can only be adjusted on the rod 70 at fixed letter-space distances. The adjustment of the rod a whole, however, by the screw or sleeve 72 enables the rod to be properly set so that the stops thereon will cooperate properly with the tabulating-stop on the carriage, which of course has a letter-space movement with the latter. For example, if the stop device be set at the point eLO on the stop-rod and when the tabulator is actuated the carriage should not be arrested exactly at 4C0 on the carriagescale, but at one side or the other thereof, on accountof imperfect adjustment or wear of the parts. The collar or sleeve 72 maybe turned either in\ ardly orout\ 'ardly, as necessary, so as to bring the stop device to a position where the carriage will be arrested at the exact letter-space point represented by the setting of said stop, or, in other words, so that in the case supposed the carriage will be arrested at the point 4:0 on the stop-bar and at the point 40 on the carriage-scale or feed-rack.

Secured to the rear side of the carriage-rail 42 by screws 84 is a stop 85, that is adapted to cooperate with the column stops or projections on the stop-rod, though said lastmentioned stops are normally out of the path of movement of the stop 85, as shown in Fig. 1. The actuating-link 63 is provided with a collar 86, that has a threaded opening therein for the reception of a set-screw 87, Fig. 5, which is adapted to bear at its inner end against the actuating-link 63, and thus maintain the collar in the position to which it has been adjusted along the link. Projecting from the collar 86 is a pin or abutment 88, that is adapted to bear upon the free end 89 of a lever 90, which is pivoted at 91 to a bracket 92, that extends from the under side of the top plate 4. The opposite end of this lever is pivoted at 93 to the lower end of a rack-lifter 9ei, that is bifurcated at 95, so as to form arms 96, the upper ends of, which are turned at right angles to the lengths thereof and constitute broad bearing-shoes 97, that are situated beneath the rack 28. The arms 96 of the racklifter are loosely seated in guiding-grooves 98, formed in the bearing 99 of the shaft 26 of the feed-pinion 27, in order that the disconnecting-piece or lifter may be guided in its vertical movement.

From the foregoing description it will be understood that a depression of the tabulating-key &9 will cause the key-lever 50 to depress the sublever 59, thus transmitting a downward movement to the actuating-link 63 against the tension of its spring 63 thereby rocking the stop-bar or rock-shaft 70 so that the tabulating-stops thereon are moved from the full-line position shown at Fig. 10 to the dotted line position represented in said ligure, and in this position the tabulating-stops on the stop-bar are interposed in the path of the tabulating-stop on the carriage. This depression of the tabulating-key 49 is likewise elfective to depress the free end of the lever by the stop 88 engaging it, thus causing an elevation of the lifter 9a, which in turn swings the rack 28 out of engagement with the feed-pinion, thereby releasing the carriage from its escapement mechanism. The carriage having been freed in the manner described and the tabulating-stops 80 having by the same movement been interposed in the path of the tabulating-stop on the carriage, the carriage will be propelled in the direction of its feed by the spring-d rum 36 and the carriage will continue to move until the stop 85 thereon reaches contact with the first of the tabulating-stops 80 on the stop-rod and is arrested thereby. Vhen the pressure is released upon the tabulating-key 49, the various parts connected therewith are restored to their normal positions by the springs thereof. During this movement the feed-rack 28 reengages the feed-pinion, and at the same time or subsequently by a further movement of the rod 70 the tabulating stops or projections 80 will be moved out of the path of the co6pits stop 88 on the link 63 enables the relative movements of the stop-bar and the swinging rack 28 to be nicely regulated or timed. Thus the higher the collar and stop are adjusted on the link the greater will be the turning movement of the shaft to interpose the stops thereon in the path of the carriagestop before the rack is released from its pinion 27. The lower the stop or abutment 88 is adjusted on the link the sooner the disengagement of the rack will take place relatively to the movement of the stop-bar. Obviously the adjustment of the abutment 88 likewise controls the relative return movements of the parts. This adjustable mechanism is of special advantage in a structure such as that shown herein and wherein the tabulatingstops are turned to and from the operative position and bear a fixed relation to the stoprod circumferentially considered.

In companion cases filed of even date and bearing SerialNos. 97,494 and 97A95 some of -my improvements are shown carried out in other forms of tabulating mechanism.
