BOOK-LOCK.

SPECIFICATION forming part of Letters Patent No. 555,829, dated March 3, 1896. Application filed May S, 1895. Serial No. 547,969. (No modeld To all whom it may concern:

Be it known that I, ERNEsT E. Roenes, a citizen of the United States, residing in the city and county of New London, State of Connecticut, have invented certain new and useful Improvements in Book-Locks, which improvements are fully set forth and described in the following specification, reference being had to the accompanying sheet of drawin The object of this invention is to provide a simple, strong, cheap and serviceable lock for books, which, while effective when in use, may be removed when no longer needed, and may also be adjusted to and used with books of various sizes.

It is frequently desired to use books of accounts in public places, where the contents of the same are exposed unless provided with some form of protection. Most commonly such books after use are placed in a safe or in a vault until again called into use. My present invention makes it possible to leave such books in exposed places-as, for example, on desks in offices or on counters in stores-with perfect safety.

To assist in the explanation of my invention I have provided the accompanying sheet of drawings, in which- Figure l is a perspective view of a book, showing my improved locking device properly mounted thereon; and Figs. 2, 3 and 4 are enlarged detail views illustrating the construction of my said device.

Referring to the drawings, the letter a denotes strips of thin sheet metal, leather or other suitable material, (but preferably sheet metah) two in number and pivotally secured together at b. The strips a are caused, when my device is in use in connection with a book, to pass around the same at right angles to each other-that is, one of said strips passes around the book, drawing across the back and front edges thereof, while the companion strip passes around said book, drawing across its top and bottom edgesas readily understood by reference to Fig. 1 of the drawings. When the strips a are in t-he positions relatively to eachl other just described, the ends thereof are so secured together as to prevent their displacement on the book, and it willbe readily understood that when thus secured any attempt to open the book would be futile.

To secure together the free ends of the strips a, I have provided what I here term a shoe c, having each end thereof upturned, as at c', in each of which upturned portions is provided an opening c2. Midway the length of shoe c is a projection or staple c3 for a purpose to be explained.

Shoe c is fiXedly secured to one end of one of the strips a by riveting, as in Fig. 2, or in any practicable manner, (said strip being passed through one of the openings 02,) and the free end of said strip and also the ends of the companion strip are all provided with openings a', located at stated distances apart in each of said ends, said openings corresponding in shape to they projection c3. The projection c3 preferably extends in a direction at an angle of forty-five degrees to the general direction of the shoe c, and the openings a designed to coact therewith are located at a corresponding angle in the strips a. When thus constructed it will be seen that the several perforated ends of strips a present a uni form appearance, as shown in Fig. 2 of the drawings.

Vhen it is desired to use my device in connection with a book, the pivoted portion of strips a is rst placed against one side thereof, and said strips are then passed around the book atright angles to eachother, as already explained. Strips a are drawn as tightly as possible, and then the free ends provided with the openings a are passed successively over the projection c3, said projection c3 entering that opening a in each of the ends of strips a which has been drawn coincident with said projection. The free end of strip a bearing shoe c, after being passed around the book, is introduced to the projection c3 through the opening c2, as clearly shown in Fig. l of the drawings, and should there be an overlapping end of said strip beyond projection c3 said end, if of sufficient length, may be passed through the companion opening rc2 to that last mentioned, said opening serving to prevent loose play of said end.

To prevent the removal of strips a from projection c3, an ordinary padlock d may be employed, as shown in the drawings, the bow IOO thereof being passed through a hole c4 in said projection and then locked, after which the strips cannot be removed from the projection until the said lock has been removed. A chain e may also be provided, whereby the lock is secured to the shoe c.

I have already stated that the strips a are pivotally secured together; thus making it possible, when the device is not in use, to swing the strips a parallel after which the complete device can then be rolled into a very small compass.

Nhile I have shown and described the shoe c, it will be apparent that this feature could be dispensed with, as the projection c3 could be as well secured directly to one of the strips a and the device be equally operative. rlhe particular advantage in employing the shoe c lies in the fact that by means of the uptu'rned ends thereof, through which one of the strips a passes, it provides bearings for said strip at points somewhat distant from the projection c3, and thus endwise movement of the strip is prevented. It will also be seen that a double form of shoe could be provided, shaped substantially like a cross, and thus sidewise play of both strips prevented. The lock d could also have substituted therefor other forms of fastening devices, as, for example, a lock operated by means of a combination, in which case no key would be needed. Y

Any possible sidewise movement of the strips a may be done away with by making said strips of considerable width, it being' apparent that When the device is locked in position upon a book the greater the width of said strips the less will be the liability of their endwise displacement thereon.

My device as a whole may be very cheaply produced, is of neat appearance, of verysimple construction, and performs in a very satisfactory manner the work for which it is designed.

Having thus described my invention, l claim- In combination, in a book-lock, two ilexible bands pivotally secured together at approximately midway their length, the ends of said bands being passed around said book and connected by a staple secured to a shoe having guide portions c c2, substantially as set forth, and a padlock secured to said staple.
