TEMPORARY BINDER.

S'PECEFECATION forming part of Letters Patent No. 337,664-, dated Marc-I'. 9,1886.

Application mea May 2o, 18515. serial No. iaoso. (Moda.)

To @ZZ whom it may concern:

Be it known that I, Farmers H. CoFFIN, residing in Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Temporary Binders; and I do hereby declare that the following is a full, clear, and exact description ofthe inventiomwhich will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to a new and useful improvement in temporary binders for sheet-music and the like; and it consists of a certain combination, arrangement, and construction of parts hereinafter specilied,where by I am able to manufacture a-nd place upon the market for publie sale a temporary binder which shall be easily operated, and constitute in every respect a highly-efficient article for general use among musicians.

In the accompanying drawings, Figure 1 shows a perspective view of my improved binder with sheets of music in place. Fig. 2 is a transverse section of the same. Fig.V 3 is a detail of the metal, backing and hinge-connected flaps. Fig. 4 is a detail of the movable slide and stationary slideway. Fig. isa front View of the binding-clamp. Fig. 6 is a detail of a binding-clamp.

Same letters of reference in the different Iigures indicate corresponding parts.

The general appearance of my binder when in use is that of any ordinary bound book. It has covers or iiaps A A, joined together by a back-strip, a', according to the usual and wellknown practice of the binderies. On the inside the back-strip a has a rigidly-affixed metallic backing-strip, b. Side flaps, cc, also of metal, are by a hinged connection joined to the strip b. Thecovers A A and side aps, cc, are joined firmly together by any suitable method of fastening. Thus a durable and convenient means is provided for swinging the covers in opening and closing by means of the metal strip or piece b, which is twice bent at right angles at its sides, so that the outer or edge portion is brought round into the dangef parallel with the back portio1i,whereby is formed the trough D, Fig. 3, extending the entire length of the back, having side passages or openings, e.

The trough l) is made of tin, or some suitable metallic material which can be readily and easily bent into the required shape and form.

H. is a slide, also of metal. Its top side is open. In general construction and appearance it is similar to the trough D. The proper position of the slide His within the trough D, where it is rmly retained by means of the flanges ff fitting over the upper edges of its sides li. That the two-parts may exactly correspond when brought together, theslideH is of slightly smaller dimensions than thetrough D. The slide and trough are united by inserting an end of the slide into one end of the trough and pushing the slide along till it is Wholly within the trough. At regular intervals along the top of the slide are placed cross-strips m. These strips are hinged at one end at the points n topone side of the slide. The other ends of the cross-strips are free.

In use the cross-strips m are fastening de- Vices for what I have denominated bindingc1amps,7 which are made as follows: o is a cross-bar bent to form a narrow slot, p, of proper size to nicely fit a crossstrip, m. s is also a crossbar. ,The two cross-bars o and s are provided at their ends with holes to receive the branches of-a wire bindingstaple, t.

The operation of attaching a sheet of music or the like to my temporary binder is as follows: A sheet of music is opened and spread out. Agagepreparedforthepurposeisplaced upon the sheet along the folding-line. This gage is equal in length with the slide H,'and at regular intervals is provided with indicating-orifices in pairs, the distance between each pair of orifices corresponding with the distances between the cross-strips m. Any desired number of orifices on the gage are selected, and their position indicated on the sheet by puncturing with some sharp-pointed instrument. Across-bar,s,islaid on thefoldingliue, the holes at the ends corresponding with the points of puncture. The wire staple t is passed through the holes in the bar s and pressed through the perforations at the folding-line. A crossbar, o, is then attached to the branches of the staple, pushed hard against the sheet, and the vwhole made secure by bending or twisting the ends ofthe branches of the staple on the under side of the bar. Two,

ICO

three, or more clamps may be attached to the sheet in the same way at the will of the operator. The clamps are then attached to the slide I-I by turning back the hinged crossstrips m, passing the strips through the slots p, and then returning the strips to their origi nal position. The slide His then pushed longitudinally' into the slideway D.

W'hen it is desired to place other sheets in the binder, all that is necessary is to slip the slide I-I from the slideway D and repeat the operation above set forth, and then return the slide to its place.

The operation of removing a sheet is obvious, and needs no extended description.

To prevent all danger of the sheets tearing away from the clamps, the foldingline is roenforced and strengthened by pasting on a .strip of paper or mnslin or any suitable material.

lt'apiece of music has an odd number of sheets, the odd sheet is attached in its proper place by pasting it to the edge ofa strip of paper, inusiin, &c., which has its other edge pasted to one of the double sheets along the folding-line.

Vhat I claim as my invention7 and desire to secure by Letters Patent, is-

l. In a temporary binder, a metallic back strip or piece having its edges bent twice at right. angles, forming a passage on eaoh side, and provided with hinged side flaps andeornbined with the covers `n, substantially as de scribed.

2. In a temporary binder, the combination of a movable slide, II, provided with hingeconuected cross-bars m, and the herein-de scribed binding'staples, substantially as set forth.

3. .In a temporary binder for the purpose of connecting sheet-s ot' music and the like tothe crossbars ot' a movable slideway, the here iii-described binding staple, consisting, essentially, ot'a staple, t, bars, and slotted bar o, substantially as set forth.

4. In a temporary binder, the combination of permanent or stationary trough D, n1ovable slide II and bars m, and binding staples, substantially as shown.

In testimony that I claim the foregoing as my own I have aiixed my signature in the presence of two-witnesses.
