Feb. 7, 19337 J, c. DAWSON LOOSE' LEAF BINDER Filed Feb. 28, 1931 liu/@72h71 5 @.Dwson Patented Feb. 7, 1933 UNITED STATES PATENT OFFICE JAMES C. DAWSON, OF WEBSTER GROVES, MISSOURI, ASSIGNOR TO ELMA N. DAVTSON, OF WEBSTER. GROVES, MISSOURI LOOSE LEAF BINDER Application filed February 28, 1931.
This invention relates to loose leaf binders and has for its objects to provide simple means for the attachment of booster levers to the cover plates of binders, and to provide booster levers and means for their attachment to binders of the wire arch frame and spring cover types.
These and other objects of the invention will become apparent from the specitication and the appended drawing, in which Fig. 1 is a perspective View of the binder and portion of the book;
Fig. 2 is a vertical, longitudinal section of the end portion of the binder, on the line 2-2 of Fig. 1;
Fig. 8 is a bottom plan view of the portion shown in Fig. 2;
Fig. 4 is a section through the binder on the line 4-4 of Fig. 2;
Fig. 5 is a vertical, longitudinal section through a binder of the spring cover type;
Fig. 6 is a vertical section on the line 6-6 of Fig. 5;
Fig. 7 illustrates the booster levers as applied to a binder of the wire arch frame type shown in a bottom plan View; and
Fig. 8 is aA vertical, longitudinal section on the line 8-8 of Fig. 7.
The binder illustrated in Figs. 1, 2, 3 and 4 comprises a spring back 11, having hooked margins 12 and 13 in which are retained the toggle plates 14 and 15. The cover plate 16 encloses the mechanism and gives it a finished ap earance. The binder is held to the book bac by means of a metal loop 17 struck up from the metal back plate 18 which passes through an aperture 19 in the spring back 11 and is locked in position by the key 21.
Two transverse ribs 22 may be formed across the cover plate 16 adjacent its ends to increase the stiffness of the cover at this point and they also prevent the paper leaves from sticking on the head of the rivet.
As indicated in the figures, the booster lever 23 comprises a thumb arm 24, and an operating arm 25 which is downwardly bent so as to give clearance to the lever when tilted about its pivot. The arm 25 projects through slots 26, 26, cut in the toggle plates 14 and 15 and terminates in a head 27 which engages Serial N0. 519,137.
the underside of the plates. Between the two ribs 22, a single rivet 28, or its equivalent, holds the booster lever suspended from the cover plate and provides a pivot point around which it may rotate. Pressure upon the thumb arm 24, therefore, lifts the toggle plates and causes the prongs 29 to separate.
The method of attachment of booster levers to binders deriving their spring action from the cover plate itself is shown in Figs. 5 and 6 and is the same as that previously shown. With springs of this type, the presence of the transverse ribs 81 is quite desirable since it prevents an undue iattening of the spring cover 32 when the booster lever 38 is depressed.
But in this particular instance, a dual action is secured and the opening of the prongs is brought about by the application of very little pressure to the booster levers. When the booster levers are depressed, the pressure transmitted through the rivet 34 causes the spring cover plate 32 to be flattened somewhat and its margins to spread apart. This relieves the pressure upon the toggle plates which are then easily forced upward by the arm 35.
I prefer to hold this type of binder to the book back by means of a clip 36 which engages recesses cut in the toggle plates 37 and 38. The clip is provided with an aperture 39 through which a loop 41 struck up from the back plate projects. A key 42 holds the binder assembled to the back.
Due to the fact that the prongs of a wire arch frame binder are formed upon the end of the arch frames, such binders are largely confined to use with the cheaper books where two arches will be satisfactory. Because this bin der holds the paper at only twoy points, the arches are located well inside of the top and bottom margins of the sheet.
A bottom plan view of such a binder is illustrated in Fig. 7 where it will be seen that the binder is composed of two identical wire arch frames 44, 44 articulated at 45, 45, and held by the curved margins 46, 46 of a channel iframe 47 which forms a cover plate. The booster lever 48 may comprise a single bent piece comprising a thumb arm 49 ending in a thumb piece 50, and a booster arm 51 having a lifting portion 52 for engagement with the arch frames 44. The booster lever is supported against the cover plateby the single rivet l53 or its equivalent, while-the binder -itself is held tothe book backbytherivet54 which ,passes Ithrough thev clearance hole '5 5 punched through the booster lever.
I prefer that the thumb arm 50 should project. above the cover plate beyondits .ends
