COPYING-BOOK.

SPECIFICATION forming part of Letters Patent No. 489,959, dated January 17, 1893.

i Application filed September 2, 1892. Serial No. 444,885. (No model.)

an elevation of the book with the roller attached. Fig. 2 an elevation of the roller dey tached. Fig. 3 an elevation of the book with the roller detached. Figa a cross section on an enlarged scale on line fc, 0c, Fig. l. Fig. 5 a longitudinal section of the roller and the back of the book. Fig. 6 a section similar to Fig. 4, with the inkstand inclosed and Fig. 7 a section similar to Fig. 4, with the book rolled upon the roller. Fig. 8 a cross section of a modification of the roller.

The letters a, a, represent the two iieXible covers of a copying book into which the leaves d', are stitched. rlhe covers a, project rearwardly beyond the leaves as at a2, to form a contracted neck. This neck terminates at its rear end in a pocket d3, in which there is contained a rod b. In front of such pocket, a strip c, of rubber or other elastic material is slipped into the neck between the covers. This strip is of triangular shape in cross section and causes the covers a, to approach each other at the proper inclination from the leaves backward toward the rod.

d is a hollow roller of wood, pasteboard or other stift' material and provided with a longitudinal slit d. One or both ends of this roller may be closed by the threaded caps d2.

Within the roller d, there maybe contained an inkstand e, a pencil f, and other writing utensils, such as a pen holder, pens, rubber, pen knife, etc.

The inkstand may be provided with a longitudinal groove e', adapted to receive the rod Z ,which thus holds the inkstand properly in place.

In use, the roller is connected to the book by removing one of the caps d2, and slipping the neck d2, into the slit d. This will canse the pocket d3, and rod o, to be received within the roller and a firm attachment between roller and book will now be elfected,because the rod is of greater diameter than the width of the slit. Y

To copy a letter, the leaves CL', are moistened as usual, the letter is put in place and the book is wound upon the roller (Fig. 7), when the hand pressure will quickly eifect the copying operation. During the winding up operation, the triangular strip c, will cause the leaves to be wound upon the roller without leaving any hollow spaces, which would of course impair the exercise of a uniform hand pressure. After the letter has been copied, the book is unwound from the roller and the letter is removed. Of course, copying books of this kind, can be made of buta limited thickness and after one book is filled, it is slipped off the roller and the latter attached to anew book. In this way,the books can be properly filed away and the roller can be used upon an unlimited number of books.

What I claim is:

l. The combination of a slitted roller, with a copying book having a contracted neck back of the leaves andarod at the end of the contract-ed neck, substantially as specified.

2. The combination of a slitted roller, with' a copying book having a contracted neck, a strip within such neck and a projection at the end of the neck, substantially as specified. JOHN P. JULIA. Witnesses:
