'[0 a!! whom it may concern.'

Be it known that l, CARI. G iinrisox, a citizen of the United States, residing at Syracuse. in the count-y ot' Onondaga and State of New York, have invented certain new and awful Improvements in Ty )ell'riting Machines, oi which the following is a specification.

Vl`his invention comprises various improvements in the carriage stops and inargin rclease devices ot' typewi itiiig machines.

'lhe invention will be described in detail hereinal'ler reference being had to the accompanying drawing, in which,

Figure l is a top plan View, partly in section, of the margin rack, margin and carriage stops, and connected parts; Fig. 2 is a front elevation of the same; Fig. 3 is a sectional View on the line A-A of Fig.v 1, .showing the connections from the vmargin rack to the line locking mechanism, and Fi". l is a section on the line B-B of F ig. l, showing the connections for operating the bell and for releasing the carriage from the margin stops.

Referring to the drawing, l indicates the rear portion of the top plate of the machine frame, and 2 indicates the back bar of the carriage frame. .l rock shaft 3 is journaled upon adjustable pivot screws et arranged in hearings 5 which are secured to the to plate of the machine at its right and le t-hand ends. Levers and i' are secured to the rock shaft 3 near its ends, and a margin rack bar 8 is secured to the forwardly projecting armsl 6 and 7 of said levers. The levers 6 and 7, and the rack har, normally rest in a horizontal position. as shown in Figs. 3 and 4, being supported on fixed points Sf. A rod or link t) is pivotally connected to the rear arm 7" of the lever 7 and to the free end of a sub-lever l0, which is pivoted upon a stud' 1l secured in a bracket. 1:3 depending from the top plate of the machine. This sub-lever is connected aty a point. intermediate of its ends to the upper end of a link t3, whose lower end is connected to a margin release key lc\cr ll. arranged atthe right side of thc machine and normally held in its raised l position against a suitable stop h y a: lsprinj y l5. 'l'he link [23 has a threaded joint lil, hy.; meansol' which the relation ofthe ke)v lever Il to the margin rack har may he regnhatcd, and the link J has a projection 9, which.: when thilink is depressed, bears upon the l end of the hell hannner 1G and moves the hammer into position to ring the hell when .the link 9 is released and moves upward.

rl`he hell ll is mounted on an arm L of an adjustable lever 42% which is pivoted at 4lto en a bracket 45 of the main frame. The lcrcr -ll has a slot lo through which passes a. clamping screw 4T. l`he hell hammer it; is pivotcd at i8 in the free end of lever -t` andl is preferably provided with a light Aspring tf1 G5 to throw it against; the hell. lt will he seen that. the slot and screw -lt and -tT provide means for adjusting the hell hammer or lever with relation to its operating means 9'l without disturbing the rclat ion of the hell 70 hammer pivot to the bell. The stroke ot the bell hammer may thus he verl,i amveniently adjusted.

A rod or link 1T has its upper end pivoted to the rear arm (3b of the lever t3, and the 75 lower end of this rod has a longitudinal slot `1T engaging a pin 18 upon the horizontal arm 19H of a bell crank lever 1t) which 1s pivoted upon a stud Q0 secured in a hanger 2l depemling from the top plate l. The ver- 80 tical arm 1t)b of said hell crank lever is arranged to operate the line lock mechanism, more particularly described in a companion application. The slot 1T permits lost motion between the rod 1T and the. hell crank 85 lever l5), so that the margin rack may be raised a sufficient distance to .sound the hell without operating the line lock mechanism, and when the rack is further elevated the line lock mechanism is operated by the movement of the bell crank lever 19, which is then operatively engaged h y the rod 1T.

The margin rack 8 is graduated, as shown,

to correspond with the letter spacing of the machine, und is provided, on its rear edge,

with notches 22 arranged one leiter space apart. margin stop 23 is provided upon the right-hand portion of the rack for regnlatin;r the left-hand margin ot' the page of printed matter, and a `stop fl is arranged 100 npnir the left-hand portion of the rack to regulate the right-hand margin. This latter .stop when engaged hy a stop upon the carriage. also causes the operation ol`v the bell and the line locking mechanism. As shown,

each margin stop hanl a longitudinal slot or oroovc '25 throu'rh which the niarem rack rrr* extends. and thc lateral walls ot' this groove flare outwardly in opposite directions from the central portion of the groove, :is indi- 110 fav catetl bv the refcreia'e character L23". :so that th tops maj,7 he ro'iml to a limitcfi extent in .i pivotal manne' upon1 `inarfgmrara bar. lach stop is provnlett vvitr :i moin 2li 5 adapted to engage the notches ir he bar. and a snrine 25D nrrfingeil within the flaring; portion of lthe groove opposite said tooth, normali f Vholil l the tooth in one of the notchcb'iin the rack 'nai'. it virili lie cviflent that brrockingthestopoasioconipress the springt, the tooth 23 may be rr-lcaSi-ii anal the. .stop moveil to an)1 lc-i1 .il portion of the liar.
