11 Claims.

This application is a division of application Serial No. 703,176 filed December 20, 1933, which issued as Patent No. 2,006,795 on July 2, 1935.

This invention relates to a summary board whereby a plurality of sheets may be suspended in horizontal overlapping relationship so that single columns on each of the suspended sheets may be held in juxtaposed positions to facilitate summarization of the data contained in the exposed columns. The invention relates particularly to means for aligning a line guide with reference to the sheets. It is an object of this invention to provide means for quickly and accurately adjusting the angularity of the line guide, without any need of tools, to insure accurate alignment of the reading edge of the line guide with respect to the sheets suspended in horizontal overlapping relationship. Other objects of this invention will become apparent upon reading the following description taken in conjunction with the accompanying drawings in which:

Figure 1 is a perspective View of my summary board;

Figure 2 is a fragmentary perspective view illustrating the housing carrying the line guide; 1 Figure 3 is a top plan View of the housing with parts broken away to facilitate illustration of the structural details; Figure 4 is a cross sectional view taken along the line IV-IV of Figure 3 looking in the direction of the arrows; and

Figure 5 is a cross sectional view taken along the line V-V of Figure 3 looking in the direction of the arrows. In the drawings, the reference numeral 2 indicates a flat plate member adapted to be supported at any desired angle by means of an easel structure 3. The preferred easel structure does not constitute part of this invention and is fully described in United States Letters Patent No. 1,883,255 issued October 18, 1932, to Paul O. Unger. The fiat plate structure will not be described in detail because it is fully described in United States Letters Patent No. 2,000,558, issued May 7, 1935, to applicant and Paul O. Unger.

The flat plate member 2 is provided with a channel shaped depressed portion 4 adjacent its upper edge. This channel shaped depressed portion 4. is providedwith a fixed lug 5 at one end and a slidable lug 6 at the other end and is adapted to receive a ring bar 1 of any suitable design. The ring bar "I is provided with open ends into which the lugs 5 and 6 are adapted to fit to secure board, it is not sufficient merely to have the sheets aligned properly, but it is also necessary to have the line guide parallel with the line of figures being summarized. My line guide mechanism includes a line guide 9 rigidly secured to a housing I adapted to travel up and down a rod II spaced from one end of the flat plate member 2 T and secured in place by a pair of flat strips I2, I3 (Figure 1) extending from one end of the plate member 2 adjacent the top and bottom. The rod I I is secured to the strips I2, I3 by means of screws or rivets. A portion of the peripheral surface of the rod II is serrated, as indicated at I4, Figures 3, 4 and 5. A metal plate I5, U-shaped in cross section, is mounted in the housing I0 on one side of the rod II. A pair of rollers I 6, I1 is mounted in the plate I by means of the studs I8, I9, The periphery of the roller I! is serrated, as indicated at 29, to enable the roller IT to mesh with the serrations I4. A pair of coiled springs 2|, 22 mounted between the plate I5 and the housing I0 exert a constant force against the plate I 5 to maintain the roller I! in positive engagement with the serrations I4. The springs 2I, 22 are positioned by 25 means of the studs 23, 24. One end of the stud I9 is extended beyond the front wall of the housing II! and carries a knob 25 which may be rotated to move the housing along the rod II The aperture in the housing through which the stud I9 passes is slightly elongated, as indicated at 26, Figure 2, for a purpose to be hereinafter described.

A roller 21 is mounted in the housing I 0 on the opposite side of the rod I I by means of a stud 28. A metal plate 29, U-shaped in cross section, is mounted in the housing I 0 on the opposite side of the rod II from the plate I5 by means of a stud 30. The stud 39 is spaced centrally of the plate 29 so that the'plate 29 may be pivotally 40 moved around the stud 30 as a center. Another roller 3I is mounted in the plate 29 adjacent its upper edge by means of a stud 32. A threaded stud 33 is rigidly secured to the plate 29 adjacent its'lower edge and extends through one wall of the housing I U. A threaded adjusting nut 34 is mounted on the portion of the threaded stud 33 outside of the housing I0. The angularity of the line guide 9 is adjusted simply by rotating the nut 34. If the free end of the line guide is lower than the end secured to the housing, the nut 34 is rotated so as to move the lower edge of the plate 29 to the left (Figure 3). Since the rod II is fixed, the roller 3I cannot move to the right, and since the housing and plate 29 are secured together by the stud 30, the plate 29 acts as a lever of the second class and pulls the upper edge of the housing to the left. The lower edge of the housing cannot move any substantial distance to the left because the slot 26 (Figure 2) is elongated only very slightly, and the right end of the slot 26 soon contacts with the stud I9. In view of the fact that the roller 21 is fixed to the housing and cannot move to the right because it is in contact with the rod II which is also fixed, the roller 2'! acts aspivot point for the housing. The portion of the slot 26 extending to the left of the stud I9 permits the slight movement of the housing with respect to the stud l9 necessary to permit the counterclockwise pivotal movement of the housing around the roller 21 as pivot. The rigid securement of the line guide to the housing causes the line guide to move angularly with the housing. It will be understood that the apertures in the housing through which the rod I I passes are sufficiently large to allow the slight movement of the housing necessary to adjust the anglr arity of the line guide.

The angular movement of the housing and line guide above mentioned compresses the spring 2|. When the nut 34 is moved in the opposite direction from that described above, the spring 2| expands and moves the upper edge of the housing to the right (Figure 3). The lower edge of the housing is prevented from moving to the right by the roller 2'! which is fixed to the housing and is in contact with the rod ll. Accordingly, the housing is pivotally moved in clockwise direction and the free end of the line guide is moved downwardly. Obviously, the degree of angular movement of the line guide in either direction can be controlled accurately by means of the threaded adjusting nut.

While I have described my invention with particular reference to its use in connection with a summary board, it will be obvious that the device may be used with any copyhc-lder or reading device where the angularity of the line guide is important. It will also be understood that the description of my device is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of my invention. Accordingly, I do not desire to be restricted to the exact construction described, except as limited by the appended claims.
