SELF-BINDING COVER FDR PAMPHLETS AND Specification of Letters-Patent.

Application filed June 17, 1912. Serial No. 764,121.

To all whom it may concern:

Be it known that}, Jnssm SMITH TRuMrnn,

citizen of the United States, residing at.

Cleveland, in the county of Cuyahoga and State of 'Qliio, have invented certain new and useful Improvements in- Self-Binding Covers for Pamphlets and Papers, of which the followingis a specification,

Thisinvention has reference to self-bind- 0 ing covers, for pamphlets and papers which it is desirable to bind together temporarily or permanently, including such matter as sheet music, leaflets, memorandum slips, bills and other papers, and the invention is an 5 improvement on the style of cover shown and claimed in an application by. F. J. Trumpet, Ser. No. 684,141, filed March 16, 1919.

.In theacco'mpany'ing drawings, Figure 1 0 is a perspective view of the complete cover, showing the inside. 'Fig. 2 is a l0ngitu-' dinal section of one of the cover sections shown in Fig. 1 but having the sheets or portions, of which it is made, spaced or 5 spread apart so as to more Clearly disclose their relation to each other, and enlarged as compared with Fig. 1. Fig. 3 is aperspect'ive view, enlarged, of a portion of one of the cover sections as hereinafter fully de 0 scribed. Fig. 4 is a perspective View showing the back of one of the-cover sections or members and Fig. '5 is a perspective view of the back proper removed from the cover. Practically the invention consists of two independent and equal cover sections or parts 0 and a single back 6 also independent and separate as an article of manufacture though of course used with the cover. The cover sections are alike in all particulars in 0 this instance though of course they might dilier somewhat in some respects and not depart from the invention. For example, there might be adjustment or elongation enough of the back in one section and no case the non-adjustable end of the back might be either temporarilyor permanently fastened in one section and all the extenthe invention as herein shown the back member 72 is adjustable or extensible alike in necessity for it in the other, and in that.

both cover sections and is provided with adjusting cords 2 at each end engaged through or about metallic or prcssboard stiffening. strips 3 suitably secured in the ends of the back, dotted lines and the said cord runs otherwise through eye lets 4 iuthcinner portion of the cover 0 and has its ends fastened together at said strip. Any other suitable means may be utilized to secure the cord to back 111cm her 6. In wide books two or more cords may be used. As to this portion of the cover my present way of making the same includes a stiifening sheet 5 of card-board or other suitable material and an inner lining 6 pasted thereon. over its entiresurface except at the edges, and when l have thus made this portion of the cover I place the eyelets t therein. The cords 2- oan'then be threaded through said eyelets and engaged at their ends as described. The next step is to apply the backing 7 upon. each cover, which is done in the present construction by lapping the edges andbuter end of the backing over the stiffening sheet and pasting the said edges down thereon. The overlapping edges of the inner lining 6 are then pasted down over the edges of the backing 7 and this por: tion of the manufacture is completed. (if course the body of theouter sheet or babking 7 of leather or fabric is free or funpasted between the edges of the cover so that a pocket is produced in. which the end of the back I) is adjustable by means of cord 2 to any desired extension, within its limits. In fact by grasping the end or ends of the cover and drawii'ig them apart they can be separated to the maximum, and

ingly. The clamping jaws cl are built into or upon the inner ends of the respective cover sections and the pockets in the cover for the back b open at the outside thereof. The said jaws haveeyelets 9 and binding cords 10 through the same. 0211 one jaw the eyelets'have spring lingers or projections 11 beneath which the ends of the cords 10 may be frictionally engaged. and which makes a simple and convenient tastening.

As a feature of this invention special stress is placed on the spring metal strips 1a which are bound into the inner edges of the backing 7 and which are made to then by pulling inward on the cord2 the back'b is drawn into the cover correspond exert their spring action inward and thus bear upon the back Z) with such measure of pressure that the friction produced will hold or assist in holding the back in any position of adjustment. The thinometal strip 3 employed across each end of the back 6, Fig. 5, is shown herein as having the cord 2 passing through a hole therein and which practically locks said cord in said strip, and the ends of cord. 2 are bound together at this point in such way as not to be noticeable on the outside. The eyelets 4: are on the median line of the section lengthwise, and each cover section in avery real sense is a complete article of manufacture and may have the cords 2 inserted therein after being completed although I prefer to engage the cord therein before the backing 7 is applied. This, however,-

is a mere matter of convenience. The pocket for the back in each section is closed along the edges and outer end and open only at the inner end of the section.

What I claim is:

1. In temporary binders as described, a cover section having a pocket open at the inner end of the sect-ion and closed at its: outer end and provided with eyelets open on the inside of the cover and covered on their outside, said eyelets located near the respective ends of the section and opening into said pocket.

2. A temporary binder for various articles comprising two independent cover sections having each. a pocket internally sub stantially the full width and length thereof and provided each with twoholes on its inside opening into said pocket and located .near the ends of theisection.

3. A temporary binder for-various papers having cover sections with inner and outer portions and a pocket between said portions open at the inner end of the section, a back adjustably held in said pockets
