Boon STRA] Application filed-January-22,1927:- Serial 1%; 1 62, 182;

My invention relates to improvements book or luggage straps and is in the nature of" an improvementon the book strap d1s= closed my copendingapplicatio'n Seria No. 93,014, filed March 8, 1926.' I

The object of myinvention is to improve the construction of book straps of this-nature and torender the same more eflicient in operation. V

Y A-mor'e specific object isto provide an endless book strap' that is easily placed aroundbook's or similar objects and'tight-' ened thereon and'that has a buckle 'oriastener within-the loop portion of said; strap which buckle is adapted to" hold the strap from working loose on .the books, said buckle being, quickly and" easily releasable manually.

Other and more specific objects will be apparent from the following description taken in connection With the accompanying drawings, wherein Figure 1 is a perspective view of va book strap constructed in accordance with my invention as it may appear when in use;

Fig. 2 is a perspective view showing the strap removed from the books;

Fig. 3 is an end elevation of the same showing the strap tightened around books; and

Fig. 4 is a sectional view on a larger scale of the buckle used in connection With my book strap.

Referring to the drawings, throughout which like reference numerals indicate like parts, 5 designates a'single one'piece strap that is passed slidably through one end 6 of a buckle 7 and that has its two ends, as at 8, fixedly secured, as by rivet 9, to the other end 10 of the buckle 7 so that said strap forms in effect a loop of double thickness fixedly connected with one end of the buckle and slidably connected with the other end of the buckle. The loop tormed by the strap is double thickness, one part being on the inside of the loop. Both of said parts pass slidably through a keeper 11.

The end Got the buckle 7 is made with an inclined surface as shown in Fig. 4 and said buckle has a flat tongue 12 mounted on a pivot 13 and provided with a relatively broad edge 14 that is adapted to cooperate with the inclined buckle end 6 in gripping the strap. The edge 14 is sharp enough to securely grip the strap by awedging action but is-not sharp enough tocut the strap,-

Saidedge- 1 1;v is preferably notched to causeto gripthe strap moreqfirm ly. A com-' pressioii spring-.15, urges theton'gue 12 into engagementwitlrthe strap/5 and said tongue maybe. moved to disengage or release the strap exerting apressure on a. thumb -piece 16' on the' 't'ongue. From the preceding description itEwiH be seen that the loop portion of the strap may be'rreadily drawn buckle in one direction but can not-be "drawn through the buckle in the'opposite.directionunless thetongue 12 is maniiall'y'ra'is'ed lor' released. 7 7 3 i 1 In placingthe strap on books 17 the strap is o ened-tilt as sliown in ,2 and -tlie banks inserted-within the loop and a u is exerted on' tli'e outeiptrfioao'f the strap between the keeper 11 and the end 6 of the buckle thereby pulling the strap through the end of the buckle tightening the same around the books and drawing out the portion on which the pull is exerted to form, a hand hold or loop 18 for engagement by the hand or arm incarrying. In tightening the strap on the books the keeper 11 and buckle 7 are preferably adjusted so that they are substantially opposite to each other and near the top edge of the books thereby preventing the books from turning over or twisting withinthe strap. When the strap is applied to the books in the manner just described a pull on the hand hold portion 18 will draw the strap through the buckle and tighten the same on the books and said buckle will engage with and hold the strap and prevent the same from loosening. To loosen the strap on the books a pressure is exerted on the. thumb piece 16 thereby raising the tongue 12 and permitting the strap to be drawn back through the buckle and loosened.

The strap is exceedingly simple in construction, holds the books positively, has no Y loose parts to become lost and is very easily and quickly put onto or removed from books or packages. r

It is also possible to reverse the position of the strap on the books letting the outer portion of the strap between the keeper 11 and the end 10 ofthe-buckle serve as a hand hold but the strap is more dilficult to apply to the books and to remove the books from when used in this manner. 7

The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my 1nvent1on but it W111 be understood that this disclosure is merely illustrative and that such changes in the device may be made as are within the scope and spirit of the following claims.

W' hat I claim is I 1. A book strap, embodying a buckle, a strap member having its two ends fixedly connected with one end of said buckle and having its medial portion slidable through the other end of said buckle, said strap forming a loop of double thickness, a keeper slidable 011 said strap, and a releasable spring pressed tongue in said buckle normally holding said strap against sliding movement in one direction through said buckle.

2. The book strap as described in claim 1 in which those portions of said strap adjacent the fixedly'secured ends are adapted to pass around books and the inner portion of the strap adjacent the slidable connection with the buckle is arranged to be drawn across the top edge of said books and the outer portion of said strap adjacent said slidable connection with said buckle is arranged to form a handhold loop.

3. A book strap, embodying a buckle, a single strap member having its two ends fixedly connected with one end of said buckle, said strap being doubled and the medial portion of said strap member being slidable through the other end of said buckle, a keeper slidable on the doubled portion of said strap, and manually releasable means in said buckle for normally permitting sliding movement of said strap through said buckle in one direction and preventing sliding movement of said strap in the opposite direction, said. strap being adapted to be placed around books with said buckle near the upper edge of the books on one side and said keeper near the upper edge of the books on the other side, the inner portion of said strap being drawn across the top of said books and the outer portion of said Strap being drawn upwardly through 'saidbuckle to form a hand hold said buckle preventing loosening of said book strap until said buckle tongue is released.

In Witness whereof, I hereunto subscribe my name this th day of January'A. D. 1927.

HENRY C. KEELER.
