FRANK J. GREGORY, OF NEW YORK, N. Y.

Book-covert.

Specification of Letters Patent.

Patented oee io, 1920.

Application filed September 8, 1919. Serial No. 322,297.-

To all whom it may concern.

Be it known that I, FRANK J. GREGORY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Book-Covers, of which the following is a specification.

This invention comprehends the provision of a book cover primarily designed for use in connection with magazines, telephone directories, or books having paper covers, the construction being such that the books can be readily and easily fastened between the sections of the cover and kept in a clean and perfect condition.

In carrying out my invention, I make use of a plurality of resilient arms which project beyond the upper. and lower edges of the cover and associated with the latter for sliding movement, the arms being extended to a position to permit the books to be quickly and easily positioned between the sections of the cover, subsequent to which the arms are moved toward each other to engage the book and hold the latter fixed relatively to the cover.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this specification, like numerals of reference indicate similar parts in the several views and where- 1n:-- 7

Figure 1 is a plan view of the book cover opened, and showing the resilient elements extended to permit the book to be properly positioned between the sections of the cover.

Fig. 2 is a transverse sectionalview taken on the line 22 of Fig. .1 showing the position of the resilient elements to engage the book.

Fig. 3 is a plan view of the temporary binder removed from the cover.

Fig. 4 is an edge elevation thereof.

Fig. 5 is a detail view of one of the resilient arms.

Referring to the drawings, in detail, 10 and 11 indicate the respective sections of the cover which are connected together in the usual manner. An elongated spacing member 12 which is substantially fiat and rectangular in cross section is arranged between the respective sections of the cover and supports the resilient arms 13 which are designed to engage the book to hold the latter within the cover. The base '12 is of a length equal to the length of the book which it is adapted to support, while the base 12 is held in position betweenthe sections of the cover by means of a fabric strip 14 which is pasted or otherwise suitably secured to the base and the adjacent sections of the cover.

The resilient arms include a body portion 13 as clearly illustrated in Fig. 5, while one end of the body portion is bent upwardly at right angles as at 15, terminating to provide a coil 16 which is extended to provide the resilient portion 17 disposed above and in parallelism with the body portion 13. As shown in Fig. 1, there are four of such arms carried by the base 12, one at each cornerof the latter, the arms being arranged so that the resilient portions 17 extend in the direction of the cover and adapted to.

move above the fabric '14: which holds the base fixed in position upon the cover. Each arm 13 slides in abore 18 provided in the base 12 and-opening at one end of the latter, while each longitudinal edge of the base is providedwith a slot 19 for each bore 18 with which the slot communicates. The

inner extremity of the arm 13 is ofiiset as at,

20, the offset extremity being adapted to engage the shoulder 21 formed by one end of the slot, to limit the outward movement of the arm.

In practice, when it is desired to position a book within the cover, each of the arms 13 is moved outwardly to occupy the position illustrated in Fig. 1. This movement of the arms is limited by the offset extremities 20 contacting the ends of the slots as above stated. The resilient portions 17 are thus disposed in an out of the way position, to permit the book to. be properly positioned upon the base 12. Subsequent to the positioning of the book, in this manner, the arms are all moved inwardly toward each other, to a position wherein the resilient portions 17 engage the book to hold the latter fixed upon or within the cover. Obviously, the construction is such that a book can be quickly associated with or removed from the cover, and when placed between the sec-v tion, the book is maintained in a clean and perfect condition.

While have shown anddescribed what communicating with said bores, resilient arms slidably fitted in said bores and having offsetextremities adapted to engage the ends of said slot for limiting the movement of the arms with respect to the said base, and each arm having a resilient portion dis posed above the base, and movable toward and away from the ends thereof.

In testimony whereof I atfix my signature.

FRANK J, GREGORY.
