UNITED STATES PATENT onrron.
Specification of Letters Patent.
Patented Nov. 28, 1905.
Application filed May 5, 1904:. Serial No. 206.491.
To all whom it may concern:
Be it known that I, LUCENA M. MoRDEN, a citizen of the United States, and a resident of 59 Grand street, Waterbury, county of New Haven, State of Connecticut, (whose post-office address is also the same,) have invented certain new and useful Improvements in Book-Rings with Locking-Sleeves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
The present invention relates to that class of book-rings which is provided with an openingin one side for applying and removing perforated sheets of paper; and the invention consists in an improved construction for a sliding sleeve to close the opening when desired and retain the papers thereon.
The construction is adapted for any ring with an opening in the side which can be spanned by a sleeve.
In the presentinvention the sleeve is formed of sheet metal bent to fit the curvature of the ring accurately and adapted to slide around upon the same to cover or close the opening when desired. The sleeve is provided with a leaf-spring having a bend or offset adapted to project into the opening when the sleeve is moved over the same, and thus prevent the sleeve from displacement until it is forcibly moved away from the opening, which movement crowds such projection or offset outwardly by contact with the body of the ring.
In the drawings, Figure 1 is a vertical section on the center of Fig. 2, which is a side View of the ring with the sleeve in section over the opening. Fig. 3 is a side View of the ring with the sleeve in section moved to one side of the opening. Fig. 4 is a side elevation of the sleeve apart from the ring;
Fig. 5 is a plan of the sleeve, showing the,
spring and the slot in which it is formed upon the outer side of the sleeve. Fig. 6 shows the blank for such a sleeve. with the spring formed by slitting the metal at one edge of the sleeve to dispose the spring upon the inner side ofthering. Fig. 8 is aside View of the ring with such a sleeve in section over the opening.
a designates the body of the ring, and Z) the opening to be covered by the sleeve 0. In Figs. 2 to 6 the sleeve is shown with a slot in the middle of its length and extended nearly Fig. 7 shows a blankto its ends, the metal punched from the slot in the blank f remaining attached to the blank at its opposite ends and forming a flexible leaf-spring (Z. Such springis provided at the middle with a drop of solder or an inward bend e, which projects slightly into the opening 12 when the sleeveis moved over the same, as shown in Fig. 2. The projection c is shown of less length than the opening; but the length of .the sleeve is so proportioned to the length of the opening that the projection prevents either end of the sleeve from slipping over the opening, and the opening is thus closed until the projection is forced outwardly. Fig. 3 shows the effect of sliding the sleeve forcibly from the opening onto the body of the ring, the projection being forced outwardly by the yielding of the spring, which bends at the middle and ends of the projection c. The tension of the spring then presses against the ring and holds the sleeve wherever it is placed; but when it is again slipped over the opening the projection crowds into the opening and retains the sleeve over the same.
Figs. 7-and 8 show a construction with the spring upon the inner side of the sleeve, the spring being slit from one edge of the blank f, but remainingattached atits opposite ends.
Fig. 8 shows the spring with the central projection adapted to crowd into the opening 6, and it shows the spring between such projection and the ends corrugated transversely to increase its flexibility and make it bend outward more easily when the sleeve is slipped endwise to uncover the opening.
The essential part of the invention is the provision of a longitudinal leaf-spring upon the sleeve with a projection adapted to crowd into the opening when the sleeve is moved over the same. i
The projection 0 may be integral with the leaf, or attached thereto, as a drop of solder. It is not essential that the leaf should be integral with the sleeve nor attached at both ends to the same; but the construction is rendered very cheap and simple by making the spring integral with the sleeve, as it can be slit or punched therefrom without any material expense by the use of suitable too Where the ring is used for securing forated sheets of paper together, it is able that the ring should turn freely it. holes of the sheets, and the formation of.
sleeve With an integral spring avoids any projections from the sleeve or ring which would interfere with such movement.
Having thus set forth the nature of the invention, What is claimed herein is- 1. A ring having an opening in one side, a sleeve fitted to slide upon the body of the ring to cover the opening, anda spring-tongue attached to the sleeve and having a projection to engage the opening to hold the sleeve over the same.
2. A ring having an opening in one side, a sheet-metal sleeve fitted to slide upon the body of the ring, and an integral leaf spring punched from the metal of the sleeve and formed with a projection to engage the opening to hold the sleeve over the same.
3. A ring having an opening in one side, a sheet-metal sleeve fitted to slide upon the body of the ring, a longitudinal slot in the sleeve with integral leaf-spring attached to the opposite ends of the slot, and such leaf-spring having-a projection to engage the opening to hold the sleeve over the same.
4. A ring having an opening in'one side, a sheet-metal sleeve fitted to slide upon the body of the ring, a longitudinal slot in the sleeve with integral leaf-spring attached to the opposite ends of the slot, and such leaf-spring bent at the middle to form the projection e, and corrugated transversely to increase its flexibility.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
