Patented Dec. 25, 1906.
Application tiled August 22,1902. Serial No. 120.612.
To (LN, wiz/fmt tana/y concern:
Be it known that I, Louis MYERS. acitizen of the United States, residing at Derby, county of New Haven, and State of Connecticut, have invented certain'new and useful Improvements in Type-Tritihg Machines, of which the followingis a specification.
l My invention relates inpart to the combination of type-bars, key-levers for operating the same, and roller-bearings tlnoughthe medium ot which the key-levers transmit moA tion to the type-bars, also to the combina-l tion of key-leverscapable of longitudinal sliding movement and a carriage-stop device controlled by the longitudinal movement of either of such key-levers, whereby the carriage may be stop ed at different points by the movement of the respective key-l evers.
In the accompanying drawings, Figure 1 is a planview of a type-writing machine illus trating the invention. Fig. 2 is a side view of the saine with some parts omitted. Fig. 3 is a vertical longitudinal section'of a part of the same on a larger scale. Fig. 4 is a rear view thereof. Fig. 5 1s a detail perspective vi ew of a stepped stop. f
` 1a 1", Soc., to 1j represent the iirst bank of a system of letter-key levers capable ol vertical vibratory movement for actuating the corresponding type-bars 26. In ord er to reduce friction between the iingerkeylevers 1 and the type-bars actuated thereby, the connection is made through a rollerlbearing 2, mounted in the horizontal arm of a bellcrank lever 10, the vertical arm of which is connected by a link 3 with a crankarm 4,
projecting from the heel of the type-bar 26, which is l'ulcrumed at 5. The roller-bearings 2 between the several key-levers 1 and the bell-cranks also permit sliding longitudinal movement of such key-levers in order that such key-levers may serve the further purpose of controlling a column-stop, as hereinafter described, for tabulating and analogous work. To this end Ithe longitudinal movementof either of such key-levers 1 *l to lj is'made to release the carriage from the escapement stop, and such movement of the several key-levers shifts to diil'erent extents a column-stop device whereby the carriage when so released from the eseapement device will be stop ed at different points, according to which key-lever is so shifted.
The key-levers 1a, &c., are provided with upwardly-projeeting rigid studs 6, adapted in the sliding movementof the respective keyelevers to engage with the horizontal lower bar of a rocking frame 11, formed as shown partly in dotted lines in Fig. 4 and fulcrumed at 11x 1n the fixed trame 38. The
function of this rocking frame 11 is to retract the sliding clutch 43, forming part of the escapement device, whenever either of the key-levers 11, &c. is slid backward, so as to release the carriage and allow it to slide under the force of a suitable feed-movement spring until arrested by the column-stop. I have shown at laa suitable feedemovement spring acting by torsion on a vertical shaft 13, on the upper end oi'whieh is mounted a semicireular vgear 14, which imparts feed movement to the carriage 51 by gearing with the rack 52 thereon.
The respective key-levers 1a to 1j in their rearward horizont-al sliding movement contact with projecting tappet-studs 12n to 12J', projecting from the bottom bar ol the stopirame 12, which is of approximately triangular form, as shown in `Fig. 4, and rocks on a horizontal axis 12x. The rocking frame 12 carries at its upper end a stepped stop 12y of triangular shape, -formed with an oblique range of steps u be, &c., to j, as shown in Fig. 1 and in detail m Fig. 5, the construction being such that the diilerent lengths oi" the tappet-studs 12UL 12", &e., with which the respective key-lowers la 1b, &o., come in contact will rock the franre 12 to a. different eX tent, so as to bring one or other oi the steps a l) c, 1&0., oi! the slop 12y to eil'oetive 4position,` accord-ing to which oi the key-levers 1? 1b, &c., is slid backward. To engage with the stepped stop 12y-tl1at 'is to say, with either of the steps thereof which is placed in the path thereof, as above described-the rocking semiolrcular gear 14 is provided with a range of sliding colu1nn.

2. ln a type-writing machine, a key-lever vibrating in a vertical plane and capable of longitudinal sliding movement; in combination with a carriage-stop device operated by the longitudinal movement of said key-lever.
3. ln a tabulating device Jfor ty e-writing machines, the combination of a pl) rality of verticallyvibrating key-levers capable of longitudinal sliding movement; a carriagestop and escapement device operated by the longitudinal movement of either of such keylevers; and tappets moved to unequal extent by the sliding movement of the several keylevers whereby the sliding movement of the carriage is arrested at different points by the sliding movement of one or other of said keylevers;
4. The combination ot vertically-vibrating key-levers 1a, 1b, 1C, capable also of longitudinal sliding movement; type-bars 26; suitable connections through the medium of which said type-bar levers are actuated by vertical movement of said key-levers; escapement-lever 1 1 actuated by the longitudinal movement of either of said key-levers; rocker-bar stop-lever 12, having stop-tappets 12a of unequal prominence engaged by longitudinal movement ot'the several key-levers so as to move-the rocker-bar stop-lever 12 to ,ditlerent extent; and the steppedstop actuated by the lever 12 and the Astop-dog carried 'by the carriage-spring gear-wheel to arrest the movement of said gear at different points according to the adjustment of the lever 12.

mechanism in customary manner.
Having thus described my invention, the following is what l claim as new therein and In operation the sliding ooluirnL stop 17 pressed and slid into operative position by 1 depressing its inclined free end by the thumb l and then sliding it forward by the applica- I tion ot a finger to its rear end until the free end is caught beneath the overhangin'g shoulder of the oscillating feed-gear. To stop the carriage on a particular column indicated by anyy number on its scale, the'proper key-lever 1a `or'1b &c., is slid backward, so as to throw the stepped stop 12y forward to the proper extent to present one of its steps a or b, &c., to the projecting column-stops 17 which will be arrested thereby on the release ot the carriage by the contact of' the stud 6 of the said key-lever with the rocking release-frame 11.
Any one of the several column-stops' 17 is selected and depressed to locate the column of igures'in the desired position on the sheet, and the proper adjustment ot the stepped stop 12F' by sliding the selected key-lever 1, cc., determines the value of the first figure printed, to represent unit-s, tens, hundreds,
Sac., and the successive figures ot the whole By the use of letter-key levers for actuating the column-stop device l am enabled to tabulate by the use of the letter-keys, and thus dispense with the necessity for additional or lspecial keysfor this purpose. The key-levers la, 5cc., are made removable by forming them at their rear end with open slots 7 as indicated in dotted lines in 2, by whichthey slide horizontally on fulcrum- 9- represents vtension-springs which may be attached atone end to the bell-crank levers 19, as shown, and at the other end adjustably in oblique notches 9a in the key-levers, so as to slide the latter 'forward into normal'posil tion when released from the rearward presj sure applied thereto to operate the column- 5 stop, as described. Said spring also serves to l restore the type-bars 26 to normal position j by drawing back the vertical armsot the i v'itnessesz J. GREEN, Ocravits KNIGHT.
