Definitions

This invention relates to an improved type action which is of the general character'of the type action used in the well-knownRoyal machine, but permits the use of flat sheet metal links of uniform length for connecting all of the key levers with the front links of the type action.
connecting links which are identical for all banks of the key levers and for all type actions of themachine.
Figure l is a longitudinal section of a portion of a typewriting machine disclosing the present invention.
Figure 2 is a side view on an enlarged scale of a portion of the various type actions.
Figure 3 is a side view of a key lever of the third or next to the lowest bank.
Figure 4 is a similar view of a key lever of the second bank.
Figure 5 is a similar view of a key lever of the top bank. I i
Figure 6 is a fragmentary view of the difference in the form of the'heels of the type bars at the center and extreme sides of the segment. 1
the invention is illustrated in a typewriting machine having a frame E in which is mounted a carriage F supporting a platen f against the front of which strikes type bars Gr which are pivoted in the type segment to turn about an axis 9.
a series of front links H, H are provided and these are all pivoted upon a rod Iatthe front of the machine.
the links H are longer than the links H and have their rearward and downwardly turned ends of a slightly diflerent form.
the links H and H are alternately arranged throughout the greater portion of the series of type action and the longer links H are connected to normal to the third and lowest bank of key levers, while the shorter links H are connected" to the top and second banks of key levers.
a plurality of longer links H are placed at. each extreme side of the series of type actions. All of these front links are returned position by the usual returning springs h.
the front links are connectcdto the heels of their respective type bars by links K and a reference to Figure 6 will show that the center type bars have a heel L which is formed somewhat differently from the heel L of the type bars at the sides of the series of type'actions.
This arrangement is shown in Patent No; 1,669,167 and is not specifi-- cally claimed herein. The purpose thereof is to assist in obtaining a uniform dip of the key levers throughout the whole series and in all four banks.
the key levers are arranged in four banks and are designated as A, B, C and D from the top to the bottom. They are all pivoted to turn about a common pivotal axis M.
the links. N. are connected to the front links at four diiferent points which lie in a horizontal plane but are placed at differeut distances from the pivotal axis of the front links.
the links N are connected to the key levers of the four banks at four different points, but these points lie in the arc of a circle which is struck from the pivotal axis M of the key levers as a center I but are differently positioned in a vertical lane.
the top blank ofkey levers A is connected to the shorter front links H by links N which are connected to the front links at points a and to the key levers at points a
the point a is the farthestfrom the pivot of the front link and the point a is the farthest from the lower edge of the keylever' A.
the second row or bank of key levers B is also connected to'the short lin'ksH by links N which are pivoted tothe front links at'points' b slightly nearer to the pivotal axis of the front link and to the key lever at point's' slightly closer to the lower edge of saichkey lever.
Thethird row or bank of key levers is connected to front links H by links N which are pivoted to the front links at points 0 still closer to the pivotal axis of the front link" and to the key lever at points 0 still nearer to the edgethereof.
Th'e'lowest bank of key levers D is connectedto front links H links N which are pivoted to the front links at the points (Z' which are the closest to the pivotal axis of the front'links and to the key levers at points d which are the closest tothebOttOm edge of the key levers.
a series of type actions each of which'; comprises key lever, aifront link connected toa typebar, and a1 conn'ectinglink pivoted to the key lever and the front link, the c'on necting links of the entir e' seiies" being of the same length' bnt connected to thekeyfl levers at different vertical points;
a series of type actionsf each of which comprises'a key lever, a front'link connected'i to a type'loar, and a" connecting link pivoted to the key lever and'th'efront link, the con nectinglinks of the entire sen-setting ofthesame length hiit connected'to the key levers at different vertical points for each bank of key levers, said points beingtlie' saine distance' from'the pivotal axisof the key levers,
