Definitions

This invention relates to an improved the operative c'onnection between the key type action inm'a'ny'respe'ct's similar to that lever D and the'front'link H. previously employed in the Royal typewrit-
the key leverDj has an'up'xvard extension er.
lever and type liar which comprise a front first of which'ov'erlies the ront link'H and linkand intermediate connections between the second of whichunderlies the same link.
the frontlink'andty'pe bar This invention
the type action comprises a drawn'through'the pins 2' and 3 with the type 'bar A pivoted in a type segment Band longitudinal axis'of the front link" the upadapted to strike against the front side of a. ward movement of the key lever will be 40 platen'C.
a key lever D is pivoted on aro'd stopped when the parts reach a certain defi- E and has arearward and downward'exten ⁇ nite po'sition'and'the' returning stop M may sion ol'adapted'toactuateja un'iversal'bar'lF. be" omitted 'ifdesired.
FIG. 6 discloses the applicationof the a pivot rod I and is extended rearwardly 'inventionto aslightlydifferent form oftyp'e 45 and downwardly and co'nnected'by a'link G action in which the 'typeb'a'rs A" arepivoted to the'lieel ofthe t'y'p'e'bar' A.
the link H is in this case also provided with a rounded portion 4-. It has been found desirable to provide this rounded portion, particularly in the first modification shown, in order that the pin 3 may contact with the link H constantly and prevent any movement of the type bar to the printing point without an accompanying" depression of the key lever far enough to actuate the universal bar.
each link N is connected by a link 0 to a universal frame P and a returning spring R is coiled about the link 0 and has one end attached to a fixed portion S.
portions 5 and 6 are struck out of the metal of the ex.- tension 1 and rounded so, that they engage the upper and lower edges of the'link H exactly as do the pins 2 and 3.
pins 7 and 8 are each provided with antifriction rolls 9 which engage the upper and lower edges of the link and facilitate relative movement between the parts.
pins 7 and 8 are employed but are positioned to engage directly with the edges of the front link H.
the pins are provided with heads as illustrated
the front link H is provided with two projecting pins 10 and 11 whichengage on opposite sides of the bent end 12 of the upward extension 1 from the key lever. This bent over end or ear is placed at a proper angle so that it will engage the pins during the pivotal movement of the front link brought about by depression of the key lever.
the general action is the same as that of the other modification.
the invention provides a very simple and efficient means for operatively connecting the key levers to the front links in the general type of type action illustrated.
a type action including a key lover, front link, type bar, and connections between the front link and type bar; means for operatively connecting the key lever and the front link which comprises an extension of the key lever and projections from such extension which have a constant engagement with the upper and lower edges of the front link.
a type action including a key lever, front link, type bar, and connections between the front link and type bar; means for operativelv connecting the key lever and the I front link which comprises an inclined ex ⁇ tension of the key level-and projections from such extension which have a constant sliding engagement with the upper andlower edges of the front link.
a type action including a key lever, front link, type bar, and connections between the front link and type bar; means for operatively connecting the key lever and the front link which comprises an extension of the key lever and projections from such extension which have a constant engagement with the upper and lower edges of the front link; and a single spring for returning the entire action to normal position.
