Application tiled May 10. 1886. Serial No. 201,716. (No model.)
at stuloseph, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in'Book, Magazine,
or l ?aper Holders; and. I do declare the following to be a full, clear, and exact descript1o n of the invention, such as will enable others sk lled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to that class of temporary binders or devices for holding papers, magazines, or kindred periodicals, designed and intended more particularly for use while suchmagazines, &c., are being read, enabling the reader to hold and read them with greater ease and comfort, said clasp being secured at one edge to one part of the cover and at its opposite edge to the other part of the cover. v it relates particularly to the peculiar construction of the spring-clasp, and to the means for securing it to the parts of the cover, and to the novel features more particularly hereinafter referred to and claimed, and shown in the annexed drawings, in which Figure 1 is a view of a section of a cover opened and provided with my improvements. Fig. 2 is a crosssection of a cover closed, and having a number of pamphlets, papers, or periodicals held in place, taken on a line through one of the spring'clasps. Fig. 3 is a perspective View, on an enlarged scale, of the spring-clasp. Fig. at is a similar view of the clasp, showing the means for securing it to,
the cover. Fig. 5 is a sectional detail view of one side of the clasp, showing the relative po sition of the strap for securing it in place.
The object of the invention is to devise a clamp which shall be simple and economical, which may be readily and instantly placed upon or removed from any paper, magazine, or kindred periodical, to enable the reader to more comfortably hold the same while reading, and, secondarily, to produce a handy cover for binding a number of such papers, whereby they may be conveniently handled and preserved in quantities till permanently bound.
Similar letters indicate corresponding parts in all the'figures.
The cover comprises the two parts A A, united at their inner edges by the flexible strip or back B, in the usual manner. It may be of any approved form and dimensions desired, according to the style and size of the periodicals to be bound.
The spring-clasp O is trough-shaped, and
may be of any desired contour in cross-section, 1
leaving a contracted opening between .its opposite sides within which the papers, &c., are held or clamped. A portion, 0, near each opposite edge is bent outwardly to fit against the sides of the cover, and slots or openings 0 are formed therein at or near the line of flexion of the portions 0, for the passage of a strap, D, which, passing around the back of the clasp, thence through the slots 0 and over the edges of the bent portions 0 of the clasp in opposite directions, affords a means for securing the clasp to the parts of the cover.
In practice the clasp is fitted in place, hav ing the sides of the parts of the cover near their edges resting against the bent portions 0 of the clasp, and the ends of the strap D, extending on each side of the clasp, are secured to the parts of the cover in any well-known manner, either an adhesive medium, riveting, sewing, or by securing them to a piece, E, which in turn is fastened to the parts of the cover.
The clasp'may be of any desired length or size, a ring one-half an inch in width being sufficient for an ordinary magazine cover and bolder; but for larger periodicals more are preferable.
The method of practical use is easily understood and requires but little explanation. The
The combination, with the trough-shaped spring-clasp having a portion near each edge In testimony whereof I affix my signature in bent to one side, and adapted to rest against presence of two witnesses. the sides of the covers, and having openings formed near the line of flexion, of the strap NATHANIEL A. HAMILTON. 5 passed around the clasp inward through said openings up and over the edges of the bent Witnesses: portions, substantially as shown, and for the GEO. F. Gomncs, purpose described. LAW. 0.
