TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed October 26, 1908. Serial No. 459,592.

To all whom it may concern:

Be it known that I, OSCAR WooDWAnD, a citizen of the United States, and resident of Montclair, in the county of Essex and- State of New Jersey, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is a specification.

Myinvention relates to 'typewrit' machines and more particularly to tabu ating mechanism for such machines.

The main object of my invention is to provide eflicient column selecting mechanism which is convenient, positive and certain of operation. I

A further object 'of my invention is to combine with said column selecting mechanism a convenient and efficient denominational selecting mechanism.

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 more 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 vertical central sectional View extending fore and aft of the machine of one form of typewriting machine embodying my invention, so much only of the machine being shown as is required to illustrate my invention in its embodiment therein. Fig. 2 is a fragmentary rear elevation of the same with the parts in section. Fig. 3 is a horizontal sectional viewtaken on the line w-w of Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is a detail perspective view of the group of column, selecting members. Fig. 5 is a detail perspective view of one of the denominational selecting members. Fig. 6 is a detail top plan view of the guide plate for the denominational and column selecting members. Fig. 7 is a perspective view showing the stops on the carriage.

I have shown my invention in the present instance embodied in a front-strike machine although it should be understood that the invention may be embodied in other styles of ty ewriting machines.

The frame of the machine comprises a base 1, corner osts 2 and a top plate 3. Fixed guide rai s a are carried by the top plate and have oppositely disposed grooved faces 5 in which anti-friction balls or rollers 6' are received, said balls or rollers being also received in grooved tracks 7 in a carriage 8 which supports a cylindrical platen 9. Extending upwardly and rearwardly from the carriage 8 are arms 10 which support a stop bar 11 provided with teeth 11 on opposite sides thereof forming interdental spaces between the teeth for the reception of bifurcated substantially U-shaped stops 12, 13, 14 and 15 shown in detail in Fig. 7. These stops have depending engaging or arresting portions 16 which project downwardly equal extents. The different stops have their engaging portionson opposite sides of the stop bar and each engaging or arresting portion has an independent path of movement with the carriage as indicated for example by the four dotted lines a, b, c and d in Fig. 7 Thus, the stops 1 1 and 15 have their depending engaging portions on one side 'of the stop bar, whereas the stops 12 and 13 have their engaging portions on the opposite side of the bar for purposes which will hereinafter more clearly appear.

A comb or guide plate 17 is secured to the top plate of the machine by screws 18. This guide plate has four openings 19 which receive and guide the

column selecting stops

20, 21, 22 and 23, the contact edges or faces of which are in a single vertical plane which extends fore and aft of the machine and therefore transversely of the direction of the travel. of-the carriage. The column selecting stops are each of a sufficient width so that when projected-it will cooperate only with the depending projection 16 of the particular stop 12 to 15 with which it is intended Thus, the foremost stop 20' to cooperate. when projected extends into the path of the depending projection on the first stop 15 of the series carrie by the carriage and only withthe stop 15, whereas the stops 21,22 and 23 co-act respectively with the depending projection on the

stops

14, 13 and 12. It

will thus be understood that each of the column selecting stops 20 to 23 co-acts only with a given one of the column stops to determine the columnar position of arrest of the carriage and that the positions of the different columnar fields maybe determined by adjusting the stops 12 to 15 to different positions on the stop bar 11.

The column selecting stops are preferably formed as part of members comprising upstanding longitudinally movable bars or sheet metal strips 24 which are shown in the present instance as ofl-set at 25 near the upper ends thereof in order to bring the stops thereon into their proper positions rela tively to the paths of movement of the stops 12 to 15 on the carriage. The column selecting stops are presented edgewise for contact with the depending portions 16 on the carriage stops and are bent as at 25 to bring the upper and lower portions of the stop members in planes at substantially right angles to each other so that the planes of the lower portions of the stop members extend fore and aft of the machine whereas the planes of the upper portions extend transversely of the machine.

From an inspection of Fig. 2 it will be seen that the column selecting stop members are fanned outwardly as at 26in order that the lower ends thereof .may properly cooperate with the rear end portions 27 of substantially horizontally dlsposed actuating levers 28. From an inspection of Fig. 3 it will be seen that these levers fan outwardly as they approach the front of the machine so as to bring them into cooperation with the comparatively Widely separated stems 29 carrying column selecting keys 30. These key stems and keys are arranged in a straight row across the machine in the key-board thereof just above the printing keys 31 at a position where they may be readily actuated by the operator. Each of the levers 28 I hasan opening therein for the reception of an outwardly extending'pivot pin 32 rive-ted to the lower end of the associated column selecting member, in order to pivotally connect the actuating lever to said member. A leaf spring 33 is riveted at.34 to each of saidlovers and extends at its free end over the outside of the associatedcolumn selecting member inorderto maintainthe pivotal connection between each key lever and its associated column selecting member and at the same time to afford a ready disconnection between the parts when desired. A

pivot rod 35 extends beneath the printing key levers 36 and constitutes a fulcrum for the various actuatin levers 28, said pivot rod being secured at 1ts ends to the frame of the machine. Each actuating lever has an upwardly extending projection 37 apertured to receive one end of a contractile sprin 38 secured at its opposite end to a hookike projection 39 on a sleeve 40 which surrounds a rod 41 secured at its ends to the frame of the machine. These springs38 restore the levers 28 and the parts connected therewith to normal ositions. The forward end of each of the evers 28 may be connected to its associate key stem 29 in any suitable manner. In the present instance each of the key stems, is formed of folded sheet metal subruary stantially into U-shape in cross section and each stem is apertured to enable a finger 42 on the associated actuating lever to be projected therethrough so as to form a connection between the key stem and lever.

A universal bar 43 extends above the rear end portions of the actuating levers 28 and is turned at its ends to provide arms 44 which are likewise pivoted on the rod 35. One or both of these arms maybe provided with an upwardly extending projection 45 like the projections 37 on the actuating levers 28 so that one or more restoring springs 46,

like the springs, 38, may be connected therewith to restore the universal bar and the that shown in the present instance being similarto the construction disclosed in my application Serial No. 415,372 filed Feb'ru ary 11, 1908.

The retarding and releasing device comprises a drum 53 containing a rotative retarding device 54 connected through a shaft 55 with a pinion 56. The inion 56 is normally out of enga ement with a feed rack 57 pivoted at 58 to 't e carriage and moved to and normally held in the position shown in Fig. 1 by a sprin 59 which bears against an arm 60 connected with said feed rack. A feed pin'ion 61 is connected through a shaft 62 with suitable carriage escapement mechanism such, for instance, as that-shown'in my application Serial No. 415,373 filed Feb- 11th, 1908. When the combined retarding and releasing device 50 is turned on its pivot 51 through an actuation of any of the levers 28, the pinion 56 is thrown into mesh with the feed rack 57, moving it on its pivots 58 out of engagement with the feed pinion 61, thusreleasin the carriage from its feed mechanism an at the same time throwing and maintaining the pinion 56 of the retarding device into mesh with the rack so that in the movement of the carriage the retarding device 54 will be rotated.

To the left of the column selecting stops is arranged a plurality of independently op erable denominational selecting stops 63, the contact faces of which are arranged in parallel planes fore and aft of the machine. The breadth of each of these stops is such that when projected to -o erative position it extends into. the paths 0 all of the depending projections 16 on the stops 12 to 15 and W111 co-act with any of these stops to arrest the carriage. The breadth of the stop 63' corresponds.substantially to the breadth of the stops 12 to 15 so that none of said last said link being pivoted at mentioned stopsis capable of passing the stop 63 when the latter is in the-projected position. The denominational determining stops 63 are preferably formed as a part of sheet metal strips, bars or members 64 which stand upright in the machine and which are individually movable in the direction of their lengths. The members 64 are off-set forwardly at 64 (Fig. 5) to bring the lower ends thereof into alinement transversely of the machine with the lower ends of the members 24 and the members .64 are also fanned outwardly at the lower end portions thereof as indicated at 65 in order that their lower ends may cooperate with levers 66. These levers are constructed like the levers 28 hereinbefore referred to and are connected, to their respective denominational stop members in the same manner as are the column selecting members and further detail description of these parts is deemed unnecessary. Moreover, the forward ends of the levers 66 are connected to denominational keys 6? arran ed in the same row across the machine with the column selecting keys 30. The universal bar 43 extends above the denominational stop actuating levers 66 as well as above the levers 28 so that an actuation of any of thedenominational stop levers will likewise effect a release of the carriage. collars 68 may be provided to properly maintain the rear end portions of the levers 28 and 66 separated. The forward ends of the levers as hereinbefore stated are connected to key stems and these key stems are guided in openings in

guide lates

69 and 70 so that the forward ends 0 the levers are thus maintained properly spaced apart.

In the operation of the machine the operator first presses the requisite column selecting key 30 in order to interpose the assbciated column selecting stop in the path of the particular columnstop 12 to 15 with which it cooperates, at the same time effecting a release of the carriage so that the carriage will be arrested after a single movement at the proper column without first arresting the carriage in'preceding columnar positions. The columnar position having been thus selected the operator releases the column selectingkey and presses the proper denominational key to select the proper denominational position Within the selected columnar field. The effect of this movement is to project the selected denominational stop into the path of the column stop which has just been arrested by the column selecting mechanism, the carriagemaking a short movement from the position of arrest by the column selecting mechanism to the'position selected by the actuation of the denominational key. 7

From an inspection of Fig. 1 it will be understood that the construction is such Suitable spacing sleeves or' the printing mechanism, although the parts are compactly arranged and the devices of one'mechanism pass through or between de-- vices of the other mechanism.

Various changes may be made without departing from the spirit and scope of the invention.
