The preferred means scribed in United States Letters Patent No. consists-of a plurality of aligning pins 2| secured 1323- 5-5 issued October 18, 1932 to Paul OuUnger. to the cover plate ".I I in any suitable manner such The/flat plate structure will not be described in as spinning;v riveting or welding. The aligning detail because it is fully described in the joint appins are preferably made of substantially the 'plication of applicant and Paul '0. Unger filed same :diameterias-the diameter of the apertures March 16, 1933 under 'Serial No. 66L080. 20 so that :the sheets fit .snugly on the aligning pins. The aligning pins 2| extend from the cover plate I! in a plane parallel to the plane of the lower exposed portion of the rings I, I2 so as to facilitate engagement of the sheets and pins. The lateral movement of this portion of the rings in opening and closing is so slight, and the rings 'are so much thinner than the pins, that the parallelism between the pins and the lower portion of the rings is substantially maintained in either open or closed position. The upper edge of each aligning pin 2| is beveled, as indicated at 22, to further facilitate the impalement of the sheets |9"on the pins. T

In the embodiment of Figure 3, thealignin pins 2| are secured to an otherwise conventional ring metal cover plate 23. The outer edges 24 of i lower exposed portion of therings is more ac-" curately maintained than in the embodiments where the aligning pins are not moved. In Figures 5 and 6, the ring metal 1 is provid with a cover plate 28 that has the end portions ofits edges embracing the curved metal plate 'III and lying between the edges of the plate "and the reinforcing member 'l'he intermediate edge portions 29 ofthe cover plate project beyond the edges of the plate 0 asclearly shown in Figure 5. Each edge of the ring bar is provided with a metal plate member-33 apertured to fit over the ring sections l2. The aligning'pins 2| are secured to the members 30 in the same'max'mer as in the case of the cover'plates i1 and 23; :Each member 30 has a plurality-of metal clips 3| weldedor riveted thereto and adapted to embrace the edgeportions-29 ofthe co'ver' plate. The clips" 3| are loose'enough to'permlt transverse movement of the members 30 relative'to the cover plate. When the rings are opened or closed-the members 30,and consequently-the aligning pins 2|, are moved with'the ring sections just usinthe embodiment of the invention. illustrated in Figure 4. i A In'order to attain speed and accuracy in'com puting data from sheets mounted on a summary board; it is not sufiicient merely to have thesheets aligned properly, but it is also necessaryito have the line guide parallel with the line of figures being summarized. My line guide'mechanism includes aline guide 32 rigidly secured to'a housing 33 adapted to travel up and downs. rod 34 spaced from one end of the flat plate member 2 and secured in place by meansof a pair of fiat strips 35, 36 (Figure 1) extendingirom one end of the plate member 2 adjacent'the top and bottom, respectively. The rod 34 is secured'to'the strips 35, 36 by means of screws or rivets. zA;por-,

. tion of the'peripheral surface of the rod 34 is 7, plate 38 by means of the studs 4|, 42.

serrations 31. A pair of coiled springs 44, 45- mounted between the plate 38 and the housing: 33 exert a constant force against the plate 38 to maintain the roller 40 in positive engagement with the serrations 31. The springs 44, are positioned by means of the studs 46, 41. One end of the stud 42 is extended beyond the front wall of the housing 33 and carries a knob '43 which may be rotated-to move the housing along the rod 34. The aperture in the housing through which the stud 42 passes is slightly elongated, as

"indicated at 42, Figure 7 for a purpose tobe hereinafter described.

'mounted in the housing 33 on the opposite side of the rod 34 from the plate 38 by means of a The stud 52 is spaced centrally of the plate 5| so that the plate 5| maybe pivotally moved around the stud 52 as a center. Another roller 531s mounted in the plate 5| adjacent its upper edge by means of a stud 54. A threaded stud 55 is rigidly secured to the plate 5| adjacent its'lower edge and extends through one wall of the housing 33. A threaded adjusting nut 56 is mounted on the portion of the threaded stud 55 outside the housing 33. V

-. The angularity 01' the line guide 32 is adjusted the housin the nut'56 is rotated so' as to move the lower; edge of the plate 5| to the 1ett(Figure 8). .Since the rod 34 is fixed, the roller 53 cannot move tothe right, and since the housing and plate 5| aresecured together by the stud 52, the plate5| acts as a lever or 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 slot42' (Figure 7) is elongated only very slightly and the right end 01' the slot 42" soon contacts with the stud 42. In view of the fact that the roller 49 is fixed to the housing and cannot move. to the right because it is in contact with-the'rod 34 which is also fixed, the roller" acts as a pivot point for the housing. The portion of the slot 42' extending to the left of the stud 42 permits the slight movement of the housing with respect to the stud 42 necessary to permit. the counter:-

housing through which the rod 34 passes are sufficiently large to allow thev slightmovement of the housing necessary to adjust the angularity of the line guide. 7

The angular movement .of the housing: and line guide above mentionedcompresses the spring 44;

When the; nut 56 is moved in the opposite direction from that described above, the spring 44 expands and moves the upper .edgeot the housing to theright (Figure 8).- The lower edge ofthe housing is prevented from moving to the right by the roller 43 which is fixed to the hous-i ing and is-in contactwiththe rod 34. Accordingly the housing ispivotally moved in clock wise 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 in detail, it will be understood that the description thereof 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.

I claim:

1. In a ring bar for summary boards, a pair of toggle plates, a plurality of sheet retaining rings on said toggle plates, and a plurality of aligning pins intermediate said rings.

2. In a ring bar for summary boards, a pair of toggle plates, a plurality of sheet retaining rings carried by said toggle plates, a cover plate, and a plurality of aligning pins carried by said cover plate.

3. A ring bar for summary boards, a pair o f toggle plates, a plurality of sheet retaining rings carried by said toggle plates, and a plurality of aligning pins intermediate of said rings, said aligning pins being adapted to move transversely when said sheet retaining rings are opened or closed.

4. In a ring bar for summary boards, a pair of toggle plates, a plurality of rings on said toggle plates, a strip mounted on said rings, and a plurality of aligning pins carried by said strip.

GEORGE H. DAWSON.
