LUQENA M. MORDEN, OF WATERBURY, CONNECTICUT.

TEMPORARY BINDER.

To all whom it may concern:

Be it known that I, LUCENA M. MoRnEN, a citizen of the United States, of 59 Grand street, Waterbury, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Yrality of holes in the edges of perforated sheets, thereby holding them detachably together for use in the binder.

The invention will be understood by reference to the annexed drawing, in which Figure 1 is a plan of the fixtures; Fig. 2 is an edge view of the same; Fig. 3 is an end view of the same with the rings closed; and Fig. 4 an end vew with the rings open.

The base a is shown of sheet-metal, with cam-shaft sockets b at one edge having a cam-shaft c journaled therein. The base has a longitudinal flange d along the opposite edge, and ears e are cut from notches e in the base andbent upwardly in pairs, and the ringsections f and g are attached together upon a pivot h and are complemental to one another so as to form a complete ring when closed.

The section 9 is held stationary by having its shank rest upon the base and upon the flange d, and it is held stationary by lugs t' bent inwardly from the tops of the ears .e. The section f is movable, and its shank adjacent to the pivot it lies over the cam-shaft c, and a cam c is formed upon the shaft adjacent to each of such sections and proportioned to press such sections against the stationary sections g, and hold the movable sections locked, as in Fig. 3.

A spring It is provided to press each of the movable pivot-sections f normally apart from the stationary sections, so that when the cams are turned outwardly as shown in Fig. 4, the sections are automatically opened to remove or change the perforated sheets. Such wire spring is conveniently supported at the side of the movable section upon one of the ears e by means of bent teeth Z punched from the ear and overlapped upon the body of the wire.

By the construction described, the pivot-bearings for the ring-sections and the socket-bearings for the camshaft are all formed integral with the base, and are readily cut and stamped therefrom by suitable tools. The cam-shaft and the cams are readily made integral Specification of Letters Patent. Application filed June 1.1906. semi No. 319.679.

Patented Nov. 12, 1907.

by bending cranks or offsets upon the shaft as shown in Fig. 2, the end of the shaft being bent transversely, or looped to form a handle for turning the same. The handle is so related to the cams that it lies upon the base out of the way, as shown in Fig 1, when the ringsections are closed.

In manufacturing the base, it is formed with projections b indicated by dotted lines in Fig. 1, which may be readily bent over the journals of the cam-shaft, as shown in full lines in Figs. 1 and 4, at the interspaces between the cranks or cams c. The base a is shown narrower than the diameter of the rings, so that the fixed sections g project over the flange d, which is notched to fit the under side of the ring and hold it laterally. It will also be observed that the transverse arrangement of the ring-sections upon the base enables the cam-shaft to be extended along the edge of the base, and that the cams operate to lock the movable sections f when they are rocked toward the sections g, as shown in Fig. 3.

The construction is very cheap to manufacture, and operates very quickly and conveniently in opening and closing the ring-sections.

Having thus set forth the nature of the invention what is claimed herein is:

' 1. In a temporary binder, the combination, with a longitudinally extending base, of complemental ring-sections supported transversely upon the base, one section of each ring secured immovably upon the base and projecting over one edge of the same, and the other section of each ring being pivoted upon the base to rock transversely, a camshaft extended along the edge of the base beneath such movable ringsections, cams upon the shaft operating to close and lock such movable sections, and a spring arranged and operated to open the movable sections when the cam is turned to release the same.

2. In a temporary hinder, the combination, with a base having cam-shaft sockets along one edge and a series of pivot-bearings projected upward therefrom, of a series of ring-sections pivoted movahly upon the said bearings, a shaft journaled in the sockets and having a cam to move each of such pivot sections, and complemental ring-sections united to the pivot and held immovably upon the base, forming a series of closed rings with the pivotsections when the cam is operated.

3. In a temporary binder, the combination, with a sheetmetal base having a series of integral transverse ears bent upward from the base to form pivot-bearings and having locking lugs thereon, of ring-sections pivoted movably upon the ears, compiemental ring-sections held stationary upon the base by engagement with the pivots and with the locking lugs, and means for moving the pivot-sections to and from the stationary sections.

4. In a temporary binder, the combination, with a sheetmetal base having a series of integral transverse ears bent upward from the base to form pivot hearings and having locking lugs thereon, of ring-sections pivoted movably upon the ears, complemental ring-sections held stationary upon the base by engagement with the pivots and locking lugs, wire springs secured upon the upturned ears and operating to hold the pivot-sections normally open and means for moving the pivot-sections toward the stationary sections.

5. In a temporary binder, the combination, with a sheet metal base having cam-shaft sockets along one edge, and an upturned flange at the opposite edge, with a series of ears bent upwardly from the base to form pivot-bearings, of a series of ring-sections pivoted movably upon the said "10 bearings, a shaft journalecl in the sockets and having a the presence of two subscribing witnesses.
