BOOK-RING.

Specification of Lettersl'atent.

Patented Dec. 1, 1914,

Application filedDecember 24, 1912. Serial No. 738,420.

To all whom it may concern Be it known that we, LUCENA M. MORDEN, a citizen of the United States, and JOHN BUCHANAN, asubject of the King of Great.

Britain, both residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Book-Rings, of which the following is a specification.

This invention relates to book rings adapted particularly for use with'looseleaf books, the object of the invention being to provide an improvedring, which may be properly designated as a knuckle or toggle-joint ring, in which the ring, usually comprising two half sections hinged together, is provided with a spring. so carried by the ring that when the ring is being opened it will, when it reaches a certain point in the opening thereof, flv open, and likewise on being closed itwill, when it reaches a certainpoint in the closing thereof, fly closed, and will remain in either of these positions.

Theobject of the present improvement, thereforepis the provision ofan improved ring of the character described constructed of two hinged members carrying a spring substantially equally and simultaneously effective on both members of the ring so that the ring has what may be termed a toggle joint connection.

The present improvement has to do with rings which are usually used independently of a back, and therefore they must havein themselves the means for opening and closing them, and formaintaining. them in either of these positions, and not depend upon the back or a part connected therewith for accomplishing these results.

In the drawings accompanying and forming part of this specification, Figure 1 is a view of one form of ring closed; Fig. 2 isa view of the same ring open; Fig. 3 is a view of the ring without the spring; Fig. 4 is a view of the spring which may be usedwith this form of ring; Fig. 5 is an under side view of the ring. shown in Fig. 1; Figs.6 and 7 illustrate views of a ring of a somewhat difierent construction, closed and open respectively: Figs. 8,9 and 10 illustrate a ring of a still different form of construction, the last figure illustrating the opposite side ofthe ring from that shown in Fig. 8, the

'ringbeing open; and Fig. 11 is a view oft.

somewhat difi'erent form of ring :construction.

Similarcharacters of reference indicate corresponding parts throughout the figures of the drawings. t

In all of the constructions illustrated herein it will beobservedthat the ring 2 comprises two semi-circularmembers 3 and 4 having some usual form of meeting ends 5, these members being hinge-connected at their opposite ends. In some forms the hinge connection comprises the usual pivotal connection or pintle between the members, as in Figs. 1 to 5, while in other forms the pintle or pivot is carried by pockets or notches in the meeting edges of therings,*as in Figs. 6, 7 and 11, while in,Figs. 8 and 9 the pivotal connection is obtained by means of a projection or tongue carried by one member and extending into a recess or groove of the other, forminga hinge on the order of a butt joint, and in all of them a spring is provided so located with relation to the hingeconnection that. the ring has to all intents and purposes a toggle-joint connection, such spring having substantially equal efficiency on both members of the ring and in.

the present instance extending about the same distanceat each side of the pivotal connection.

In the form shown in Figs. 1 to 5 the hinged ends of the ring membersare pivotally connected by a pivot 6 extending through rabbeted or overlapping portions 7 of the ring members, which are for this pur' pose preferably cut away a predetermined distance at each sideof the pivot, as M8, and the outer margin of each ring member is provided with a notch 9 for the reception of the spring 10,which spring in the present instance is of an elongated loop formation and suitably bent tohave its outer ends 11 extend into the notches 9 in the margins of the ring members and also bent intermediate such ends. as at 12, to conform to the peripherv of the ring. a

In the form shown in Figspfi and 7, the meeting ends ofthe ring members are provided with notches 13 for the reception of a pin 14 and are also provided with slots 15 through which a spring, 16 extends, this spring being provided with a loop 17 ex tending intothe interior of the ring, and a pair of laterally extendingends 18 having while the spring fits in this cut away or recessed portion and thelaterally extending ends 21 of this spring extend into openings and may be headed over on the opposite side of the ring in any suitable manner,

In all forms of the improvement it will be observed that the spring is provided with ends of onefo rn or another which engage directly with the ring members themselves and is also provided with what may be considered a loop intermediate portion extendmg around or past the hinge connection and conforming in some forms thereof to the peripheral shape of the ring. The spring is located in such a manner that the ring will be maintained closed or open, and both halves of the ring may be opened together equally, and when partially open the, spring will cause them to fly open and remain open and when partially closed beyond a certain point the spring will cause them to fly closed and remain closed.

In all forms of the device shown, it will be observed that the spring is located centr'ally with relation to the pivotal point of the members forming the ring and that the spring has part connected to each of said members, this connection being obtained by inserting an equal portion of the spring into ea'ch'of the ring members'so that the spring et's with equal force on both members of the ring;

It is to be understood that the various details may be more or less modified without departing from the spirit or scope of this improvement. 7
