  • the typewheel assembly comprises a shaft 33 with a cylindrical rack 34 rigidly mounted thereon.
  • the type-' wheel 32" has sixty-four characters arranged in four rows offsixteen characters each. As .is indicated in Fig. 5,
  • the-surface of the typewheel 32 is divided into two semicylindrical portions with one such portion having the figures characters thereon and the other having the letters characters thereon.
  • the figures-letters shift is accomplished through the rotational positioning assembly 27 and will be described in detail hereinafter.
  • the type positioning assembly functions as two cooperating units with the rotational positioning being accomplished by the two-stage eccentric assembly shown in Fig. 3, and the axial positioning being accomplished by the triple eccentric assembly shown in Fig. 5, the former positioning function being controlled by the last three impulses of a five unit code and the latter being controlled by the first two. While the positioning mechanism is illustrated in conjunction with a typewheel, it is obvious that it is adaptable to other types of movement such as linear or rectilinear positioning. The specific linkage and number of eccentrics is intended as a preferred embodiment and should not limit the scope of the invention.
  • the rotational positioning assembly comprises a slidably mounted rack 36 which is engaged with the typewheel pinion 35 so that movement of the rack 36 will cause rotation of the pinion 35, and thereby rotation of the typewheel 32.
  • Pivotally attached to end 30 of the rack 36 is an interponent 37 (Fig. 2) having an output lever 38 pivotally attached to the end remote from the rack 36 and a second output lever 39 pivotally attached midway between the rack connection and the remote output lever connection.
  • the two-stage eccentrics 41 and 42 are identical and are suitably mounted to bring two levers 43 and 50 (Figs. 3 and 4) into position to be pivotally connected with the output levers 38 and 39.

  • the lever 43 is rigidly fixed to the cylinder 48 for rotation with it and is pivotally connected to the output lever 38.
  • the relative distances between the axis of rotation of the shaft 44, the cylinder 48, and the connection point of lever 38 are proportional so as to impart horizontal movement to lever 43 in three increments, thus enabling lever 43 to position the lever 38 and, through lever 38, the upper end of the interponent 37 in any one of four different positions. It is, of course, understood that by varying the distances and the amounts of rotation, an infinite number of positions could be obtained.
  • the eccentric assembly 42 is essentially the same as the described eccentric assembly 41 wherein elements 50, 51, 52, 53, S4 and 56 correspond to the elements 43, 44, 46, 47, 48 and 49, respectively.
  • the pinions 46, 49 and 52 are engaged by pull bar racks 57, 58, and 59, respectively, while the pinion 56 is engaged by the shift pull bars 61 and 62.
  • the rotation of the pinions and thereby the associated portion of the eccentric assembly is accomplished by the selective movement of the pull bar racks, the selection and movement of which will be taken up in detail later.

  • a second cylinder 71 is eccentrically mounted on the first cylinder 67 with its axial center line 72 a given distance Y from the axial center line 68 of the first cylinder 67 or a distance X plus Y from the axis of rotation 69 of the shaft 63, and parallel thereto.
  • the second cylinder 71 is mounted for rotation through 180 about the axial center line 68 of the first cylinder 67.
  • a third cylinder 73 is egcentrically mounted on the second cylinder 71 with its axial center line 75 a given distance Z from the axial center line 72 of the second cylinder 71 or a distance X plus Y plus Z from the axis of rotation 69 of the shaft 63, and parallel thereto.
  • the third cylinder 73 is so mounted as to rotate through 180 about the axial center line 72 of the second cylinder 71.
  • a pinion 74 is rigidly aflixed to the second cylinder 71 and concentrically mounted with respect to the axial center line 68 of the first cylinder 67, so that rotation of the pinion 74 will cause rotation of the second cylinder 71 about the axial center line 68, of the first cylinder 67.
  • a second pinion 76 is rigidly attached to the third cylinder 73 and concentrically mounted with respect to the axial center line 72 of the second cylinder 71 so that rotation of the pinion 76 will cause rotation of the third cylinder 73 about the axial center line 72 of the second cylinder 71.
  • Pull bar racks 77, 78 and 79 are engaged with the pinions 64, 74, and 76, respectively.
  • An output lever 81 (Fig.
  • the output lever 81 is connected to a slidably mounted rack 82 which is engaged with an arcuate segment 83 of a segmented pinion 84.
  • the segrnented pinion 84 has a second arcuate segment 86, Wl'llCh is engaged with the cylindrical rack 34 on the typewheel shaft.
  • the segmented pinion 84 is pivotally mounted at the pivot point 87 so that movement of the axial positioning rack is transmitted through the pivoting of the segmented pinion 84, to the cylindrical rack 34 and thence through the typewheel shaft to the typewheel 32.
  • five axial positions for the typewheel are provided. There is a retracted position for last letter visibility which is the state when none of the cylinders is rotated from its position as described above. This condition exists at the end of each cycle.
  • the second cylinder 71 is rotated in each cycle. When the second cylinder 71 is rotated 180 about the axial center line 68 of the first cylinder 67, it is apparent that any point on the third cylinder 73 and thereby the output lever 81 will move a linear distance of 2Y. In the same manner, when the pinion 74- is also rotated through selection of its associated pull bar 78, the output lever 81 will move a linear distance of 2Y plus 2X.
  • the fourth and fifth typewheel positions are similarly attained through the selective rotation of the pinion 76 along with the pinion 74 or the rotation of all three pinions.
  • the selective rotation of the pinions which are an integral part of the positioning device as outlined in the preceding paragraphs is accomplished through their associated pull bar racks.
  • the engagement of the pull bar racks provides a positive action for rotating the pinion and its associated eccentric when selected, and for preventing rotation when not selected.

  • a cam portion 94 of the push bar 22 is moved against a cam portion of the intermediate interponent 96 causing the interponent 96 to pivot about the pivot point 97, and move the punch selector interponent 26 to the left thereby selecting the number 4 punch lever in a manner such as is defined in the aforementioned De Boo patents.
  • the pull bar bail 92 is yieldably related to the intermediate interponent 96 so that a simultaneous result of the afore-mentioned movement is to pivot the bail 92 about the pivot point 97 and move its bottom portion and loop 80 to the right.
  • the pull bar rack 58 being engaged by the loop 80 is pivoted on its pinion 49 in such a manner as to engage the cross bar of the power bail 29, which is in its lowermost position at the selection stage of the cycle, beneath the shoulder 98 of the pull bar rack 58.
  • the power bail 29 is then moved upward by the oscillation of the lever 99 which in turn is driven from the power shaft by means of an eccentric cam and link (not shown).
  • the upward movement of the pull bar rack 58 rotates the pinion 49 and its associated lever 43.
  • the intermediate interponents 96 are each associated with their respective bail 8893 through the co operation of a pin 85, carried on the upstanding arm of each bail, and a vertical slot in the intermediate interponent. Interponents 96 are pivoted about the common pivot bar 97. Under normal operating conditions, each intermediate lever 96 and its associated bail moves as a unit about their common pivot point 97 except that the pivot hole of the intermediate lever 96 is in the form of an open-ended slot, and each lever 96 is biased against the pivot shaft 97 by a yield spring 95.
  • the pull bar racks 77, 79, 58 and 59 are operated in the manner just described.
  • One of the rotation controlling pull bar racks 57 is positioned to the right of the power bail (Fig. 8) with its bail engaging shoulder toward the power bail 29.
  • the pull bar rack 57 is controlled by the fifth impulse of the code and is engaged by the power bail 29 at all times except when the fifth impulse is marking.
  • the pull bar rack bail 93 and the pull bar 57 are pivoted as described above with the exception that the pull bar rack 57 is moved out of the path of the power bail 29 rather than into it, for a purpose to be hereinafter described.
  • Fig. shows diagrammatically the sixteen horizontal positions of the end 30 of the typewheel rack 36 as positioned by the interponent 37 in response to the selective operation of the pull bar racks 57, 58, 59, 61 and 62.
  • the output arms 38 and 39 are not shown, in which event the interponent 37 is positioned directly by the levers 43 and 50.
  • the pinion and pull bar racks are of course not shown.
  • the last three units of a standard five unit code control the rotational positioning of the typewheel.
  • the third unit controls the rotation of the lever 43 while the fifth unit controls the rotation of the shaft 44 (Fig. 3) and thereby said third and fifth units control the horizontal linear position of the lever 43 and the cylinder 48 about the center of which it pivots.
  • the fourth unit controls the rotation of the shaft 51 (Fig. 3) and thereby the horizontal linear position of the lever 50.
  • the neutral or home position, as indicated by H in Fig. 10 occurs when none of the pull bar racks 57, 58, or 59 (Fig. 3) has been selected. It should he noted that this occurs when the fifth code unit is a marking pulse.
  • pull bar 58 (Fig. 3 or 8) is selected by a third code unit marking pulse so as to rotate the output portion 102 of lever 43 to point A
  • pull bar 59 is selected by the fourth code unit marking pulse to rotate shaft 51, and move the output portion 100 of lever 50 horizontally from point C to point D.
  • Pull bar 57 is selected by a fifth code unit spacing pulse to rotate the shaft 44 and move the output portion 102 of lever 43 horizontally to point B.
  • the interponent37 is similarly positioned from the home position to the positions shown in Fig. 10 with the code combinations associated therewith.
  • the shift and unshift function is accomplished by rotating the typewheel 32 from the letters home position 4 to the figures home position 4. This involves rotation of the typewheel through 180 or eight angular typewheel units or spaces. In order to conform to the established code, shift and unshift functions must take place on 1245 lcode combinations and 1-23-4-5 code combinations respectively. The selection and operation of the shift function is most easily seen by referring to Figs.
  • the shift selection assembly consists of two sensing arms 103 and 104 pivotally pinned at one end and urged toward the selection bail extensions 106 by associated springs 107 and 108.
  • a lever 109 is pivotally mounted on the pin 111.

  • the bail engaging shoulders of the pull bar racks are so constructed as to engage the bottom of the power bail 29 on its downward stroke.
  • Four of the selector bail extensions 106 are formed having a shoulder 128 and a groove 129. The extension of the selector bail 91 has no groove.
  • the sensing arm 103 is so positioned as to be unblocked when all of the selector bails are pivoted, and the sensing arm 104 is so positioned as to be unblocked when selector bails 88, 89, 92 and 93 are pivoted and move under the extension of selector bail 91 and into the grooves 129 of the others, selector bail 91 being controlled by the third code unit.
  • the selector bails 88, 89, 92 and 93 are rotated to move pull bar racks 77, 79 and 58 into the path of the power bail 29 and pull bar rack 57 out of the path.
  • the selector bail extensions 106 are moved down to unblock the sensing arm 104 and allow it to strike the hammer 118 of lever 109 to pivot said lever 109 clockwise (Fig. 8) about its pin 111.
  • the pivoting of lever 109 in a clockwise direction (Fig. 8) moves the cam extension of the lever 109 away from the extension 116 of the shift selector bail 117 thereby allowing the selector bail 117 to be rotated in a counterclockwise direction about its pivots 119 and 121 (Fig. 8) by its spring 124.
  • Counterclockwise rotation of the selector bail 117 causes the loop 105 to move to the left (Fig.
  • the sensing arms 103 and 104 are moved away from the selector bail extensions by any suitably timed means.
  • the letters shift code combination unblocks the sensing arm 103 and allows it to strike the hammer extension 123 of the selector lever 112, thus pivoting the lever 112 about itspivot point 113 and unlatching the selector arm N9 so as to cause the lever 109 to be rotated in a counterclockwise direction by the spring 114 causing the cam extension 115 of the lever 109 to cause the extension 116 of the selector bail 117 to be rotated in a clockwise direction thereby causing the loop 105 to be moved to the right (Fig.
  • the typewheel corrective mechanism may be operated from a power shaft through an eccentric assembly (not shown) or any other suitable means to move a lever 124 into one of the positioning grooves of a corrector disc 126 which is slidably keyed to the typewheel shaft 33, and a second lever 127 (Fig. 1) into the cylindrical rack 34.
  • the foregoing operation is, of course, accomplished just prior to the printing operation as indicated on the timing diagram in Fig. 9.
  • the operation of this invention may be more clearly understood by following its functions in printing a character. Assume that the shift is in the letters position, and that the armature 21 is responding to the letter C code signal, wherein the second, third, and fourth impulses will be marking, while the first and fifth impulses are spacing.
  • the selector mechanism 23 selects the push bars 22B, 22C, and 22D and moves them to the left to contact the intermediate interponents 96B, 96C, and KB.
  • the intermediate levers 96 and bail extensions are thereby rotated about the pivot point 97 to move the associated punch interponents 26 to the left to position the second, third, and fourth punch levers, and at the same time move selected bails 89, 91 and 92 and their associated pull bar racks 79, 59 and 53 to the right to position the pull bar racks in the path of the power bail 29.
  • Reference to the timing diagram of Fig. 9 indicates that the power bail 29 is in its lowermost position while this selection takes place. While the selector bails are so rotated, the shift sensing arms 103 and 104 are allowed to move toward the extensions 106. They are, however, blocked from actuating the shift mechanism by the extensions of selector bails 93, and 88, which are not selected.
