Patented Oct. 11, 1932 UNITED STATES PATENT OFFICE ADOLPH e. LOTTER, or MILWAUKEE, WISCONSIN, ASSIGNOR ,TO H. 0. MILLER 00... or

MILWAUKEE, WISCONSIN a l RING BINDER Application filed November 18, 1927. Serial No. 234,107.

This invention relates to ring binders.

In ring binders as heretofore constructed it is the usual practice to provide a spring clip extending the full length of the binder and provided with movable members carry ing the half ringsections so that they may be either snapped open or'snapped closed.

Other types of binders have been proposed, such as shown in the copending application of H. C. Miller, for visible record system, filed in the United States Patent Ofiice, De-

cember 10, 1925, Serial No. 74,523, and now matured into Patent No. 1,787,755. In this latter type of binder, means have been provided for sliding one set of half ring sec.- tions with reference to the other set thereof. However, this form of binder is adapted for a direct inward motion of the ring sections and does not employ the spring type, as described immediately above.

This invention is designed to provide a spring type of ring binder which is so constructed that the half ring sections may be shifted longitudinally soas to bodily shift the sheets carried thereby one-half space with reference to the opposite rings, thus permitting the sheets to be turned over onto the opposite rings and transferred in a shifted position, as described in cletailin the above Further objects are to provide a very simple type of spring binder which is so constructed that the shiftable half ring sections may be very readily attached thereto and permitted to shift when the binder is open and to provide a construction which is easilyproduced, which is easy to operate, and which is reliable in operation. I

An embodiment of the invention is shown in the accompanying drawings in which':'

Figure 1 is a view of the central portion of the binder with the covers, which are only partially shown, laid out flat;

Figure 2 is an end view of the structure shown in Figure 1;

Figure 3 is a detail showing the manner in which the back is fastened to the spring portion of the binder;

.0 Figure 4 is a view corresponding to Figure 1 showing the rings open and shifted-a half space; v

Figure 5 is a sectional view on the'line 55 of Figure 4; a

Figure 6 is a detail of the endv structure of the binder showing the clip for retaining the slide in either of two positions. 1

Referring to the drawings, it will be seen that the binder comprises an arcuate spring member 1 (see Figures 2 and 5) which is pro-. vided with inturned ends 2 and 3. The inturned ends receive the rocking plates 4 and 5. One of the rocking plates, "for instance, the plate 5, has rigidly attached thereto the ring carrying plate 6, The other ring carrying plate 7 is slidablycarried by the plate 4,as will The plate 6 carries the hereinafter appear. half ring sections 8 and the plate 7 carries the half ring sections 9. The binderis adapted to be snapped open or closedby pulling upon the half ring sections 8 and 9. There is a toggle action secured byfithe arcuate spring land the plates 4 and 5, as is obvious from reference to Figures 2 and 4. Prefstuds 11 secured to the plate 4, thus permit-- ting free longitudinal sliding of the strip or plate 7. This plate 7 is provided with a manipulating handle 12 adjacent one end and is provided with an aperture 13 adjacent the other end. The aperture 13'is adapted to receive the rounded projecting portion 14 of a spring 15 secured to the plate 4, as shown particularly in Figure 6. This engagement of the a erture and projecting portion 14 is secure when the plate 7 is slid upwarde ly as viewed in Figure 4. When the plate 7 is slid downwardly, as shown in Figure 1,

the projecting portion 14 snaps upwardly beyond the end of the plate 7 and thus temporarily locks it in closed position. The plates 4 and 5 are each provided with notches which receive the contracted portions of beaded studs 16, as shown in Figure 5.-

. the ordinary capacity of a spring type ring:

These headed studs constitute therefor the bearing portions of the plates 4i and 5 and permit the toggle action referred to, and as best shown in Figure 5, the depth and width of the annular channel forming the contracted portion of each stud 16 is such that when the binder is open as illustrated in Figure 5, the edges of the notches in which.

thecontracted portions of the headed studs are-received, co-act with the top and bottom of the annular channels forming said contracted portions to prevent movement of the plates 4 and 5 beyond a predetermined degree and to thus retain the plates assembled with the spring back.

A, very simple means is thus provided whereby the spring ring type binder may be used for shifting the recordL sheets as heretofore described without any cumbersome construction whatsoever, but instead in a very cheap; and simple manner.

Further it. is to be noted that the additional fatuires cooperate with the ring type bineer to secure the shiftable features without however, sacrificing any of the securities of attachment of the parts or the interlocking of the half ring sections.v The spring stop 14. arrests the motion of the shiftablev plate 7 carrying one half of the ring sections at either of two predetermined points to thus insure correctspacingor-correct registry of the rings, so that the binder may be used inbinder and: also may be used for shifting the sheets.-

It; is to be noted also that this binder may be". very readily attached to a back by the construction illustrated. inFigures 1. and TlHS'lS secured by PI'OVlCllI-l-g' an extra plate 17 having upstruck tongues: 18 pas through slots 19 in the bottom. of the spring. 1 and clamped downwardly in place. These tongues passthrouglrv the back. 20 and" the en;- tire back is covered with suitable fabric in zaccordance with the usual practice, such fabric being omitted from Figure 3 for the sake ofclearness.

These tongues are preferably made of triangular shape, as shown particularly in Fig.-

sure 1, and the plates 5- and 6, andv l and. 7,

not only has the characteristics of the springtype binder but also provides for the shifting ofone set of prongs with reference to the otherset of prongs.

and as the scope of such invention is to be determined as claimed,

I claim:
