TYPE-WRITING MACHINE.

To all whom it may concern Be it known that I, FRANK C. Rosnn'rs, a citizen of the United States, residing -in This invention relates totabulatingmech- 'anism for typewriting' machines, and its obmeans for setting the column stops into opcrative positions, and to restoresaid stops to inoperative positions.

A column stop is provided to correspond The column stop is asuitahly formed plate, normally held out of operative position by a spring, and is actuated by a dog which releases it from said spring and turns it into "operative position; said-dg being in turn actuated by a key at the keyboard .01 the machine. A key is providedon a rotatable ban-to bear against a keyway provided on each column stop, and thereby turns all of said stops to inoperative positions.

Other features and advantages will here-j inafter appear.-.

In the accompanying drawings, Figure 1 is a general perspective view showing" the "stop arrangement. Fig. 2 is a side vlewof the stop arrangement. Fig. 3 is a side View of a part of the machine.

away, as seen from the rear of the machine. Fig. 5 is a detail of the column stop. Fig.

Beferring to Fig.3, a platen 1 is mounted on a carriage 2, which travels on guide bars ennui, attached to the machine frame 5.

-' Decimal stop rods 6, disposed at the rear of the machine,'sre operated by pressing keys 7- mounted on levers 8, at the keyboard.

An index?v is attached to the carriage 2 to cooperate with a carriage scale 10. These parts are all common in the Underwood typewriting machine illustrated. Column stops 1 1 are carried on a bar 12 parallel to the ans of platen l and adjacent to the upper or stop portions 13 of the tabulating stop rods 6. Said barl2 is pivotally mounted in hearings it formed on end brackets 16 extending from the carriage 2. The rim 11 are mounted 0:: bar 12 to Specification of Letters Iatent.

brackets 15. On the edge of the carriage 2' is formed a projection 20, adjacent tobar 12 and extending throughoutits length, to which are fastened detent springs 21, which I normally engage the ends 220i projections 23 formed on the column stops 11. -Said ends 22 are yieldingly detained in the dented parts 24-01 said springs, and thus the stops 11 are maintained out of operative position, F ig. 2. l

To set any column stop 11 to operative position, a dog 25 is moved down againsta cam edge or surface 26 formed on stop 11, and thereby swings it about the bar 12,. as shown in Fi 1, to the operative position at Fig. 3. T e dog 25 is formed on the, end oflcver 27, which is conveniently shaped as shown in the perspective Fig. fi st) to be mounted pivotally, by meansflof'screws 28, on the frame 29 which usually .incloses the tabulating levers 6, and is fixed to the machine frame 5. To the lever'27 is pivoted a link '30, which in turn connects, p votally with a lever 31, and the latter leads to the keyboard in front of the machine, as shown in F ig. 3, where it is provided with a key 32. A spring 33 normally holds this lever, as well as. parts 30 and 31, in the position shown in Fig. 3, and thereby maintains the dog 25 in the raised position. When the key 32 is pressed down the dog 25 comes down and turnsihe column stop to the o erative position. The dog 25 is oppos e the index 9 ofthe machine, or directly abov the decimal point stop rod 6, so that by moving the carriage, each column .stop 11 corresponding to any division of the can riage scale 10 can he placed directly under said dog 25 and set thereby. In order therefore to set up a desired arrangement of stops, it is merely required to move the carriage to any position on the carriage scale at which a stop is desired, and press the ke 32, which willhring the corresponding col umn' stop 11 into operative position. An arm is formed on said stop 11, which abuts against the guide bar 19 when the stop Patent-ed July 1, 1913.

is in operative'position, to limit its movement; the spring 36 fastened on projection 20 pressing on the edge of the stop at 37 to prevent its accidental displacement from the operative position. The bottom part 38 of the stop is suitably formed so that the edge 39'thereof is horizontal, and disposed, when in operative position, to abut against the top part 13 of any stop rod (L when it is set, as showigin Fig. 3. On the bar 12 is provided a; shaft-key 40, which, when the bar is rotated on its axis, bears against the edge 41 of the notch 42 in the edge of the bore 16 of' each set stop, The key 40 thus causes any set steps 11 to swing back to normal inoperative position, where the dented end 24 of detent spring 21 rciingages the end 22 of the, stop. On the end of the bar 12 a finger lever 43 is rigidly fastened by'set screw 44 to rotate the bar 12. A spring 45, fastened to a projection 46 extending from bracket 15, holds the bar 12 and shaft key 40 in the normal positions shown in Figs. 1' and 3. Thus, when it is desired to restore the column stops 11 to inoperative positions in order to set up a different arrangement of stops, the finger lever 43 is swung toward the frontof the machine, which gives the bar 12 a fractional turn, and the shaftkey 40 actuates all the column stops that may have been set, and restores them to the inoperative position. The lever 43, when released, is returned by the spring 45 to normal posit-ion.

In tabulating work, the carriage 2 which carries the platen 1 is released by any one of the tabulating keys 7, at the keyboard, which are mounted on the levers 8. The tabulating key lifts the stop rod 6, which actuates lever 47, pivoted at 48 by means of the projection 49 pressing the end 50 upward. Said lever 4-7 pulls the link 51 downward to depress the end 52 of lever 53 pivoted on bar 54. This forces its opposite end 55 to lift the rack bar 56, attached to the carriage 2, from the pinion 57, which is rotated by the escapement 58, and thereby releases the carriage 2. The carriage, being released, moves freely until the set column stop 11 abuts against the raised stop 3 of rod 6. The tabulating key then being released, the rack bar 56 again engages with the pinion 57, and the stop rod 6 drops to normal position.

Having thus described my invention, I claim:
