IN VEN TOR tion pulley thence uruvardly where its end is connected with a lug?r G upon the pivoted iulcrunied |ype-t'arryinpr bar 7.

The operalon of the device Will then be as follow 'z \\'heuever any type or character key is depressed, the spring between it, and the plate C will be compressed, and the pressure upon the key will press the plate down. This conu'n'esscs the springs C/ beneath the pla-te and allows th'e stein of the key to act in the slotted end oithe. segment bar 2, which end being depressed, 'tlie opposite end will be raised, and through the' cord will act upon its tparticular key as described. \\'hen tb e plate (I again rises it moves the d etent lever.l (t to release a tooth o1 theescapement wheel, and this allows the spring at H to act upon the gears l, I, and thus turn the roller K, and advance the carriage a dist-.mee equal to the space between the vletters; the geariin,r and escapement being designed to produce such a movement.

ln this construction it will be seen that the typ'e always strikes. upon a liat surface upon which the paper lies, instead ol' a cylindrical one, as in the case ot` type-writers in which rollers are employed as platens over which the paper passes, and against which the keys strike, and by my construction the clearness ol tbe characters will be improved, and the manifoldin;r power oi the machine will be considerably increased. i

'lhe imprint. oi the type is produced by means oi an inkinej ribbon shown extending across below the carriage in Fig. l, which passes around rollers F disposed in suitable relation with the'earriage, and with relawhen depressed. a spring-pressed escalnuueut' actuated lu' the depression of said plate, and connections between the escapelnent: and the bearin",lv wheels oi' the carriage whereby the carriage is moved at each impulse a distance equal to the space between cha 'actors 2. ln a t'ylwwriter, a carriage having l'wariue wheels upon which it is movable transversely, fulcrumed t vpe ne' bars, keys and levers h v which said type, barsI are actuated, a smilie-pressed member underlying the keys and actuated b v the latter', a spriue'pl'essed eseapement actuated b v said `member in unison with the depression ot any key, said escalmment comprising' a ratehetnvhoel aud a detent lever said lever havingY two pawls to en ;'ae'e said ratchet wheel, and having' an arm which extends through the said sprinwpre ed member, and gearing' between the cscapement and bearing wheels whereby the latter are simultaneously revolved to advance the machine4 .'i. ln a uvm-writer, a frame or body, wheels upon which it, is movable transve ly.'l'ulcrumed type bars, rollers and an inkine' ribbon passing' thereovcr in a plane between the frame and the surface over which it is movable, an openingI through the t'rame through which the types may be propelled to imprint through the ribbon uprfn the surface beneath, depressible keys by which the type bars are actuated, a plate beneath the keys willi which each key contacts when depressed, spring-pressed escapement mechanism actuated by the depression o1' the plato, and gearing between said escapement' and the bearing-wheels whereby the latter are moved at each impulse to advance the ma chine a space equal to that between the letters.

4. ln a typewriter, a frame having hinged bars carryingY types upon their ends. keys by which said types are moved and the type projected through the center oi the frame, .an inkine' ribbon carried below said trainen-ind parallel with the surt': 'e to be imprinted, bearing; rollers or wheels journaled to ltravel parallel with the lines to he imprinted, an escamnnent and intermediate u'ing whereby the wheels are turned to advance the cali mec, a plate through which the stems otf'the linger-keys pass. springs upon' said key stems located above and below the plate. said plate being' depressible in unison with the key movement, and an eseapemcnt pawl carried by the plate.

In testimony whereot` l have hereunto seit my hand in presence of two subscribing witnesses.
