IMPROVEMENT IN BOOK-CLAMPS.

Specilication forming part ol' Letters Patent No. 148,249, dated March 3, 1874; application filed December 29, 1873.

To all whom 'it may concern:

Be it known that I, DAVID SEAWRIGHT, of Pittsburg, in the county of Allegheny and tate of Pennsylvania, have invented a new and useful Improvement in Book-Clamps; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing` Inaking a part of this specification, in which- Figure l is a side elevation of my improvement, and illustrates the method of carrying a book. Fig. 2 is an edge View, and Fig. 3 is a sectional View, of thel box containing the pencil-case.

My invention consists ot' a book-carrier, in which the sides are secured to each other by means ot' adjustable elastic bands fastened by friction-buckles.

To enable others skilled in the art to make and use my invention7 I will describe its construction and manner of use.

0n the upper end ofthe side a', and on both ends ot' the side a., is a piVoted friction clasp or buckle, d, and pressing upon the same a spring, c, which holds said clasp down against the face of the sides a a. At the upper end ofthe holder the band e is passed through and:

under the friction-clasps (l.V It may be inserted by drawing back the springs c and then slipping it through' the clasps. This band, being held simply by the friction of the buckle, may be adjusted to form a holder of diii'erent widths. Upon the lower end of the side a there is a hook, y, which is arranged opposite to the clasp on the lower end of the side a. The band lL is passed through the clasp on the lower end of the side a, in the saine manner as has been described with reference to the band e, having a looped end, which may be drawn across and slipped ou the hook g. This band maybe lengthened and shortened, in the manner described with reference to the band e.' Attached to the lower end of each pie-ce a a is a stay or stop, k, to

afford a more extended bearing-surface for the books which arev in the holder. The ends of these stays are bent inward. The holder is provided with a handle, t', which is secured by the cords i.

This holder is used as follows: The hands being adjusted to the proper width with reference to the books to be carried, the books are, placed in it, and the lower strap is drawn across and looped upon the hook. In case the weight of the books carried is great, their tenl dency is to fall out cornerwise.4 This I prevent by means of the stays k, the bent ends of which extend under the projecting edges of the books and prevent their tipping either way.

One great advantage of this holder is that the carrying-strap is at the end. In most of those in use it is at the side. The latter is very troublesome' and inconvenient, because the corners of the books strike against the person carrying.

In connection with this holder, I have formed a box, m, upon one of the sides a. This box is for the purpose of containing pencils and other articles of like nature.

My improvement is a convenient, easily-adjusted, and greatly-superior holder.

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

l. The combination of the sides a a', the friction-clasps d, springs c, bands c h, and hook `g, the whole forming a clamp for carrying books, as described. i

2. In combination with the clamp, formed by the sides a a with their adjustable lendfastenings, the stays k, for the purposes described.

In testimony whereof, I, the said DAVID SEAWRIGHT, have hereunto set my hand.

DAVID SEAWRIGHT.
