LIBRARY HELPER AND BOOK STORAGE This invention relates generally to'library furniture.

A principal object of the present invention is to provide an improved library ladder having having self-contained means to support a number of volumes of books in a convenient manner so that the same may be transferred therefrom and the upper shelves of a library bookcase.

Another object of the present invention is to provide a library helper and a book storage which incorporates a stepladder mounted upon casters so that the same may be moved along the front of the library bookcase so to gainaccess to different portions thereof.

Yet another object of the present invention serves to provide a library helper and book storage which includes a plurality of shelves on top of the ladder so as to support in a convenient manner a large quantity of the books.

Other objects of the present invention are to provide a library helper and a book storage which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is the sole FIGURE of the invention and is a perspective view of the present invention.

Referring now to the drawing in detail, the reference numeral 10 represents a library helper and book storage according to the present invention wherein there is a stepladder unit II at the lower end thereof, the stepladder unit being surmounted by a book shelf unit 12.

The stepladder unit II is comprised of ladder 13 formed of vertical runners 14 between which there are a plurality of steps 15, the upper end of the runners being surmounted by a platform 16. The platfonn 16 is relatively broader in a forward direction so as to provide a convenient place upon which to stand while a person is working on the higher shelves of a library bookcase.

The shelf unit 12 is comprised of a pair of spaced-apart sidewalls 17 between which there are provided a lower bookshelf 18, an intermediate bookshelf l9, and upon the upper end of which there is removably mounted an upper bookshelf 20 of relatively greater length. The lower ends of the sidewalls l7 are integral with a pair of downwardly extending legs 21, the lower end of the legs 2] and the lower end of the runners 14 having wheeled casters 22 secured thereto so as to allow the device to be easily pushed along a floor of a library.

It is to be noted that the sidewall 17 and the forward legs 21 of the device need not necessarily be made of a single part but may be made separate if so preferred by a manufacturer. lf madeseparately, it will be obvious that the shelf unit 12 may be made removable from the ladder unit ll such as by the removal of a wing nut 23 from bolts 24 that are used for en gaging the two units together.

ln operative use, the device may be pushed along the front of a library bookcase and a person may easily mount the ladder steps to the platform 16 where he may place books between the shelves l8, l9 and 20 to the library bookcase shelves. The top shelf 20 may be readily removed when desired for easy portability and storage.
