` 'UNITED STATES PATENT OFFICE- HERMANN H. HOFFMANN AND FRANCIS HERMAN HOFFMANN, OF CHICAGO,

' ILLINOIS.

BLANK-BooK.

SPECIFICATION forming part of Letters Patent No. 487,014, dated November 29, 1892 Application filed August 18, 1892. Serial No. 443,382. (No model.)

To all whom it may concern:

Be it known that we, HERMANN H. HOFF- MANN and FRANCIS HERMAN HOFFMANN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Blank-Books, of which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our invention relates to certain new and useful improvements in books, the same being especially adapted for blank-books, and particularly to t-he manner of attaching the leaves or pages to the backing, so that when the book is opened the pages will lie perfectly at.

In a patent granted to us December 1, 1891, No. 464,325, we have shown, described, and claimed a blank-book comprising a number of sections or signatures, each stitched separately through the central fold, combined with a suitable hinge or guard secured to the backing and having a suitable filling-piece, said hinge being attached on both exterior sides of the section at the fold, and we have also included in said patent a hinge or guard comprising a strip or strips of fabric having end pieces or parts, a filling-piece secured to said strip or strips, said end pieces being adapted to receive between them the sections or signatures. It has been found in practicethat books constructed in accordance with said patent, while very strong and durable andless expensive than the majority of books on the market, cost rather more than some man ufacturers care to expend; and it is the object of the present invention to make a book which will cost very little, if any, more than the common old-style books and yet be as strong and durable as the hinge or guard books, which cost much more to manufacture.

Our invention therefore consists, primarily, of a book comprising sections or signatures and a series of stubs, each composed of a strip folded once in the center and then each half folded, said sections or signatures being secured to the side folds in said strip.

It consists, secondly, of a guard or hinge for blank-books, comprising a strip of canvas or like material folded with one central and two intervals, said sewing-band being formed like an accordion-belt. The sewing of all the sections of the book onthis one band necessitates all sections to be carried along on the sewing-- machine until the last section is sewed, and this, to say the least, is a very tedious and troublesome operation. Then, again, to sew this endless band, with all the sections sewed thereto, to the parchment is another awkward operation, for, as the sewing is commenced at the bottom, it necessitates the employment of extra help or a contrivance to hold up the balance of the sections for the sewer. In our invention we do away with this extra expense and make a stub which holds two sections compact on it, filling up the spaces of these stubs with strips of boards or other material to the thickness of the two sections, thereby enabling us to sew and stitch with great convenience.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective View of a .portion of a book made in accordance with our invention. Fig. 2 shows the strip before folding; Fig. 3 shows it when half-folded, and Fig. 4 when in condition for use.

In the drawings, A represents a portion of a iiat opening book constructed in accordance with our invention and composed of the sections or signatures B.

C is a strip of canvas, muslin, or other suitable fabric of any desired length and width. After cutting these strips the desired length we fasten four lling-strips a a a a to one side of the fabric and then fold the latter with the fillers in four equal parts,`the filling-strips lying between the folds, as shown in the drawings. The first fold in the strip is then laid IOC guard, the staples being clinched on the insidek of the fold of the strip,the head of said sta-v ples being upon the section. The other part of the guard is then turned to the saddle and the second section stapled thereto in the same manner as the first, so that two sections are fastened to one stub. It will of course be understood that these parts may be secured central fold of the strip to the sewing-,bandsor parchments D,thebindingbeingthencompletedfin the usual manner.`

Having thusdescribed ourfinvention, what we claim as new, and desire to secure by Let@ ters Patent, isu

1.v A blank-.bookcomprising sections or sig-i natures, a-series .of stubs, each :composed of a strip folded in the center and then each half folded, said sections or signatures being socured to the side folds, substantially as described.

2. A guard or hinge for blank-books, comprising.. a strip of canvas or like material folded with one central and two side folds,withfilling-strips secured between the folds, substantially as described.

3. A blank-book comprising sections or signatures, a series of stubs, each stub composed of a strip folded once in the center and then each half folded, and filling-strips secured to said foldedstrip between the folds, said sections'or signatures being secured to the folds in said strip, substantially as described.

4. A blank-book comprising.,sectionsorsigf natures, .a series# ofl stubs, each composed lof a strip offcanvaso-rfother fabric folded with one central andA` two ,'sideffolds; illing-stri-ps secu red to the' fabric'Y betweenthe folds. and onv the under sidel of.v said fabric, and lmeans for securing. the leaves of the lsection forsigf nature vtogether and zto theside folds, substan-` tially asf described.

In witness whereof; we afxoury signatures inpresenceof two witnesses.
