BINDING BOOKS.

Specification ofLetters Patent No. 17,299, dated May 12, 1857.

To all whomc't may concern Be it known that I, ARCHIBALD H. Row- AND, of the city of Allegheny, in the county of Allegheny, in the State of Pennsylvania, have invented a new and improved mode of preserving and extending the durability of the bindings of books and folios or large blank books, ledgers, &c.', and thereby at the same timegreatly facilitating removing of said books to or Vfrom the shelving or racks on which they rest in a vertical position when not in use, which Aimprovement is embraced in the application of grooves of brass or other suitable metal or material, into which rollers have been introduced, after which the grooves or book-carriage is attached `to theflower end of the covers of the book, by which great stiffness is given to the cover and at the same time the binding is protected `from wear and friction in passing the bookto or from its vertical resting-place.

The other improvement, or part of the improvement, consists in the application of a spring or clamp` constructed of metallic or other elastic substance, applied near the top, or at the top, of the head band, and generally on the outside of the back or outer binding; the ends of which spring are so applied as to press on the extremity of the arch formed by the inner back, or headband of the book by means of which pressure the said arch is caused to retain its proper full and original form, and thereby prevents the leaves which compose the book or folio from leaning forward, or sagging, and, eventually tearing, or separating the outer back and cover, from, the head band or, inner back, (sometimes called the spring back) and I do hereby declare thatithe following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing a book or folio with a book carriage, one for each side of the cover, which carriage is so constructed and of such shape as to leave a groove above the rollers on which it moves, which grooved part receives the lower end of the cover and to which it is secured by rivets passing thro-ugh it, thus supporting the cover, and enabling the book by means of the rollers in the carriage to be moved with ease and comparatively trifling wear or friction, while also by means of the spring or clasps embracing or pressing on the extremities ofthe head band, o-r spring back, and thereby maintaining, said head band (when the book is closed) in the form of an archprevents theweight ofthe leaves, from settling down, as is now the case, when, the book is left in a verticalposition and without the application of my spring. i

To enable others skilled in the art, to make and use my invention, I will proceed to `describe its construction and operation in its several parts.

I construct my book carriage of any metallic or other suitable convenient material, either with one continuous groove and with rollers at proper intervals placed therein, o-r apply the carriage in divisions containing one or more rollers to each, segment or subdivision-fthe size of the grooved case as also that of the rollers working therein being varied to suit the size and weight of the book.

I construct my back clasps or spring of any suitable elastic material, susceptible of tempering, shaping its form and Asize to the back or outside of the book to which it is to be applied, and so adjusting its length as to cause its extremes to come in contact with the extremes or ends of the head band or inner back of the book, and when thus applied, at or near the top of the book, as when in a vertical position causes the leaves of the book (in consequence of the arch form thus given to the head band) to be maintained in the same position as if the book were resting on the back instead of on the ends, and while thus preserving the leaves in place, the strain on the back, to which large books are subject is overcome, and the binding, besides retaining .its proper form, when the book is resting in the usual vert-ical position, will also be found to last longer and less subject to crack at the joints of the book, than is now the case.

Reference being now had to the annexed drawings, making a part of this specification, will more fully explain my said invention and the mode of constructing and using t-he same.

Figures l and 2 are the grooves con- 'taining the rollers and which support the book when in vertical position. Figs. 8, 3, 3, &c., show the rivets as holding the carriages on the books. Fig. t shows the lower side of the groove with the rollers in. Figs.

5, &c., show form of rollers out of the groove. Figs. 6, 8mo., are the rivets used in fastening the grooves to the book. Figs. 7 and 8 show the bur and washer for securing the rivets.

Letters refer to the book when the clasp or spring is applied.

A shows the book with only the head band or inner back on.

B shows the book with full back of binding without the clasps.

C shows the book closed with full binding and the spring or clasp on.

" book (a back view). y

E is the spring by itself, ready for use on the book.

F is the book on its side with, book carriage and spring applied.

Gr shows the joint or hinge part of Lthe book.

H, H, is a side view of the back when book is shut.

I is the book carriage or groove containing the rollers. J is a View of the book with spring and carriage, as on the shelf.

K shows the action of the book open when spring is attached.

L is the head band or inner binding, spring inward.

M is the outer binding spring outward.

N is the spring when the bookis open and O is the spring when the book is closed.

What I claim as my invention and des-ire to secure by Letters Patent, is-

l. The combination of the rollers in the groove or book carriage as applied to books to aid in moving them in their racks in a vertical position.

2. I further claim the application of the spring as above described and -used in compressing the extremities of the arch of the head band and thereby causing said head band to maintain a circular or arch like form, by means of which t-he leaves of a folio or book are kept from drooping or sagging when the book is in a vertical position; this spring I use according to convenience or choice either, applied on the outside of the outer back, or neXt to the head band or inclosed between the outer and inner back.
