' obvious from this construction that the with the spacing of the letters to be. printed pressure of the type carried by the type-bar against the paper upon the platen may be very accurately -adjiisted, and this pressure willalways be uniform no matter'how many thicknesses of paper are placed on the platen, since .the yielding type-bar guide accommodates itself to the difterem thicknesses of paper upon the platen and its stop 19 accurately limits the throw of the typebar under allconditions. t Thetypebar guide as shown is preferably mounted-iiponthe paper-carriage so as y .will be clear that accurate spacing of the let upon the paper. In other Words, each. step to receive the. next type -bar;

by step movement of the platen past the printing point brings anew notch to receive and guide a typebar,jand thus the type-bar cannot be made toprint bet-weeii' the space of two letters. Furthermoracollision of the diitere nt.type bars within the notches of the guide is practically avoided since the notches-ofthe guide are siiiiicient to. receive but one type-barflat same, and as soon as this type-bar is withdraw'iifrom itssprinting point a new notch is presented layers ofpaper are wound upon the platen,

.. they come in contact with the edge ofthej guide which lies adjacent to'the platen and displace the guide "outwardly or it'orwardly.-

Hence when'a 'greater niimber of layers of paper'are placed on theplaten, a'sin' making a great "number of'carbon copies, the guide arrests;the'movement 5f the type-bar .at a greate tdist'ance from the face of'the pl'aten' roller." It is understood that when the type- 'bar strikes theguide, the platen forms a 1 "backing-1 to support the" guide" against the v effect of the'blow delivered by the type-bar.

The present embodiment ofmy invention;

herein shown and described is only the pre-- ferred one ofjthefmany forms my invention may tak'eyand it is tobe understood that my invention 'r'nay be embodied in any of the .formsbroadly included; in the appended claims.

2. A type-bar guide for typewriting machines comprising a plate mounted adjacent the platen with a notch therein for guiding the type-bar, and having a stop for limiting the throw of the type-bar, said guide and stop being arranged to automatically adjust itself relatively to said platen corresponding to the thickness of paper thereon.

3. .A type-bar guide for typewriting machines comprising a plate with a notch {therein for guiding the type-bar and having to travel therewith, and therefore after they 'printingof-each letter a newnotchis pre sented for then'ext' type-bar due to'the lat-' eral movement of they paper-carriage tor, spacing the letters under the infiue'nceof the; usual escapement.,- By this construction it atstopengaging the type-bar adjacent the type thereon for limiting the throw of the type against-the paper, said guide and stop being mounted adjacent said platen and airranged to yieldingly bear against the same for automatically accommodating itself to a thickness of paper on said platen.

4. A type-bar guide for typewriting niachines compris ng a plate mounted longitudinally of the platen of the machine, said platen having a'pliirality of notches there in spaced acco ding to the spacing of the letters-to be printed, and adapter l to guide atypebar.
