HENRY T. SISSON, OF PROVIDENCE, RHODE ISLAND.

PORTFOLIO.

Specification forming' part of Letters Patent No. 23,506, dated April 5, 1859; Ressued March 13, 1866, No. 2,199.

To all whom it may concern:

Be it known that i, HENRY T. SIssoN, of the city of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Portfolios and Paper-F iles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1, is an inside view of an open portfolio with my improvement. Fig. 2, is a central longitudinal section of what I term the barrel which forms the back of the portfolio. Figs. 3 and a are transverse sections of the portfolio near the middle of its length. Figs. 5 and 6 are transverse sections of the same near one end but in different planes.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in a novel apparatus which may be applied in the back of a portfolio or attached to a suitable handle for the purpose of holding and securing music sheets, pamphlets or papers of any kind.

To enable others to malte and use my invention I will proceed to describe it.

A, is what l term the barrel consisting of a tube of metal, wood, or other material somewhat longer than the papers which are intended to be held, said tube being left entire for some distance, say from half an inch to one inch, from each end, and having nearly one half the intervening portion cut away in a plane parallel with its aXis, having an opening a, a, of a length equal to or somewhat greater than the length of the papers. To one side of this barrel there are permanently attached two or more pointed hooks or teeth o, curved in a form to correspond with the arch of the barrel and extending nearly across the opening o, a. as shown in Figs. 3 and t.

B, is what l term the shaft arranged within the barrel, extending from end to end thereof, and projecting slightly from one end thereof. The terminal portions of the shaft are cylindrical and fitted into the complete tabular terminal portions of the barrel so as to turn freely therein; but the part of the said shaft which enters the open part a, a, of the barrel, is half cut away or has a cavity formed in it corresponding with the opening a, a., and one edge of this part is formed to project beyond the interior of the cavity a, (l, so that it may lap over either side thereof as shown at e, c, in Figs. 3 and 4, 'and in this lapping part c, c, there are openings d, CZ, (see Fig. l) to permit it to pass the hooks or teeth Z). In the flat portion of the shaft there is formed a recess whose back e (see Figs. 3 and Ll) constitutes a gage for the edges of the sheets.

The marginal portion of that side of the cavity over which the fiat side of the por tion c, c, of the shaft laps and to which the hooks or teeth b, are attached, is made fiat to correspond with the shaft and the marginal portion of the other side of the cavity beveled to correspond with the rounded side of the shaft. Provision is made for inserting the shaft in the barrel by making a p0rtion of one of the complete tubular portions of the barrel movable, and when inserted the shaft is secured by replacing and securing the movable portion of the barrel.

q, q, (Figs. 2 and G) are coiled springs applied in suitable cavities formed between the complete tubular terminal portions of the barrel and the portions of the shaft which fit thereto, and having each one end attached to the shaft and the otherlto the barrel and operating to turn the shaft in a direction to press the lap c, o, toward the flat side of the cavity a, a, as shown in Fig. Il. j', is a spring latch attached to the inte rior of the barrel within one of its complete tubular portions, and g, is a stop formed on the shaft to engage with said latch and hold the shaft whenever the latter has been turned to the position shown in Fig. 3. rlhe spring of the latch y, has attached a button 2'., which protrudes through to the exterior of the barrel for the purpose of applying the pressure of the thumb or linger for liberating the stop g, from the latch and leaving the shaft under the influence of the springs d, d.

The shaft has attached to the end which projects from the barrel a finger piece or head m, which may be taken hold of to turn it, and this head is all that needs to project from the ends of the portfolio. The boards C, C, of the portfolio are simply attached by cloth or leather to that side of the barrel B, which is left entire, by means of a back y', of cloth, leather or other substance, and straps 7c, is, may also be applied to connect the interiors of the boards with the opposite or inner halves of the complete tubular terminal portions of the tube.

To place music or other sheets in the portfolio, it should be laid open and the shaft B, turned in the barrel A, till the stop g, catches the latch f, as shown in Fig. 5, which brings the recessed face portion of the shaft to the position shown in Fig. 3. The sheets are then held loosely in the hand with the edges which are to be secured Linder the points of the hooks or teeth b, I), and close against the gage e, as shown by the red lines in Figs. 1 and 3, which represent them, and on the button z', being depressed to liberate the Vstop g, from the latch f, the springs el, d, carry the shaft rapidly to the position shown in Fig. 4;, driving the sheets on to the hooks or teeth and down to the heels thereof and throwing them over to the position indicated by the red lines in Fig. et, leaving them clamped between the lap of the shaft and the fiat face or edge of the barrel. In case of the springs not being strong enough to force the sheets over the hooks or teeth, the shaft may be turned by taking hold of the head m, and the springs will not fail to hold it when turned.

By the simple omission of the boards C, from the barrel A, the same contrivances which I have described for holding sheets in a portfolio, constitute a ile for holding newspapers or other sheets, but for the file I should prefer to substitute a handle for the simple finger piece or head m.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

The combination of the barrel A, shaft D, hoolrs'or teeth b, Z), a spring or springs d, d, spring latch f, and stop g, the Whole constructed and arranged substantially as and for the purposes herein set forth.
