8 Claims. (Cl. 197-127) The invention relates to paper aligners for recording machines, such for instance as a Monroe listing adding machine having a shiftable carriage provided with a platen and a pivotal front feed paper guide having an upper straight edge and pressure rolls engaging the platen to feed a paper work sheet during rotation of the platen. According to this invention there is provided a manipulable means for moving the paper guide to open throat and closed throat positions, as well as to an incomplete closed throat position, prior to moving the paper guide to complete closed throat position, to loosely frictionally grip said sheet between said rolls and the platen to permit manual adjustment of the work sheet with respect to said straight edge to align the last printed entry on said sheet. The manipulable means is also arranged to operate means for rotating the platen subsequently to moving the paper guide to complete closed throat position to feed the work sheet reversely from its direction of insertion but in normal line feeding direction for entry of a new item is given linear relation to said last entry. Another ob- I 'ject is to provide a second manipulable means for adjusting the effective stroke of the pawl of a ratchet and pawl means for rotating the platen one line or alternatively two line feeding and consequent spacing of the printing lines of the work sheet. Other objects and advantages will appear hereinafter or will be obvious.
The invention consists in the novel construction and combinations of parts as hereinafter set forth in the claims.
In the accompanying drawings,
Figure 1 is a plan view of a listing adding machine having the invention applied thereto.
Figure 2 is a side view of the invention as applied, the carriage end frame being shown as partly broken away, the paper guide being shown in completely closed throat position, and the second manipulable means being shown in position as adjusted to shorten the effective stroke of the pawl for one line feeding of the work sheet.
Figure 3 is a section on the line 3--.-3, Figure 1, the carriage end frame being shown as partly broken away, the paper guide being shown in open throat position.
Figure 4 is a view similar to Figure 2, with parts omitted, showing the pawl of the ratchet and pawl means in the position assumed with the paper guide in the open throat position of 2 fective stroke of the pawl for two line feeding of the work sheet.
The invention is shown as applied to a Monroe listing adding machine, such for instance as disclosed in the Crosman Patent No. 1,946,572, dated February 13, 1934, modified in accord with the disclosure of the Crosman Patent No. 2,323,205 dated June 29, 1943, so far as the general type of machine and of the carriage are concerned.
In the drawings, the numeral l designates a shiftable carriage having mounted thereon a rotatable platen 2, and a front feed paper guide 3 pivoted at its lower end at 4 to the carriage end frames 5 and tending to fall by gravity from normal or closed throat position (Fig. 2) to open throat position (Fig. 3), said paper guide having pressure rolls 6 which when in closed throat position (Fig. 2) engage the platen to cause a paper work sheet I to be fed during rotation of the platen and having an upper straight edge 8, located when in closed throat position in horizontal alignment with the longitudinal axis of the platen.
Manipulable means are provided for moving said paper guide to open throat and to closed throat position in such a manner that prior to moving the paper guide to complete closed throat position, the paper guide is moved to incomplete closed throat position to loosely frictionally grip the work sheet 1 between said rolls and the platen in such a manner as to permit manual adjust ment of said sheet with respect to said straight edge to align the last printed entry on the work sheet. The manipulable means is arranged to operate a ratchet and pawl means for rotating the platen, subsequently to moving the paper guide to complete closed throat position, to feed the work sheet reversely from the direction of insertion for entry of a new item in given linear relation to said last entry.
