SPECIFICATION forming partofletters rat tiva'seaear, dated. m 3,1894.

Application filed June 27, 1892..v

Be it known that 1, JAME S.S.MODONAL1),a citizen of the United'States, residing at 'Chi cago, ln-the county'of Oook'and State'of Illinois, have invented certain new and useful I any suitable form, suchfor. instance, as that Improvements in Holders for Manifold Books and Carbon-Sheets, of which the following is a full, clear, and exact specification.

My invention relates to devices for holding asheet of carbon in positionon a book to be written upon and it is'designed as an improve-1 ment on a device of this character shown and claimed in my United States Letters-Patent No. 4 79,014. 7

The invention has for its object to provide a simple and effective device for this purpose by means of which thecarbon sheet holder may be conveniently and quickly clamped in.

position on or removed from the leaves or book to be written upon. I

With these ends in view, my invention con-- sists in certain featuresof novelty in the con-' struction, combination and arrangement. of parts by which the said objects and certain other objects hereinafter described are ac: complished, as fully set forth with reference to the accompanying drawings and more parformed-longitudinally in the rear side of a spring tube or} sleeve I, at a slight distance iapartjhus'forming keepers for holding the lovers in'place and at the same time constiticularly pointed out in the claims.

In the said drawings, Figure 1, isa plan view of a book, tablet or number of leaves, showing a sheet of carbon held invplacetherefl on by means of my improvements. Fig.2, is a sectional view of the same, taken on the line 33, Fig. 1. I Fig. 3, is a similar view on an enlarged scale, the jaws being also indicated in dotted lines, in ,their "released position. Fig. 4, is'a vertical longitudinal section taken on the line 44, Figs. 1 and 2. Fig. 5, is a view similar to Fig. 1, illustrating a modification of the means of connecting the carbon sheet holder and book holder together. 'Fig. 6, is a vertical longitudinal section taken on the line 66, Fig. 5. Fig. '7, is a transverse section taken on the lines 77, Figs. 5 and 6; and Fig. 8, is a further modification of the or clamp being shown in dotted lines and the book or leaves being-omitted. Like signs of reference indicate like parts throughoutthe several views.

' In the drawings, A indicates a block of Y allel. thumb piece or lever G, which levers or thumb sheets, blank orders or the leaves of the book $erialNo. 43 8,139.: (roman to which the carbon" sheet holder Bfis to be secured for holding thesheet of carbon Ein I to be written upon-,as the case may be, and v shown in my aforesaid patent which consists of a case '0 composed of a strip bent substan-' tially into a U form in cross-section and having pivoted therein. a blade or strip D for pressin'gthe'. edge of the carbon sheet E into the frame, as will be readily understood; or instead of this form, such a carbon sheet fholder as shown in United States Letters-Pate out, No. 131,071, granted to me July 1, 1890,

might be employed, but 7 any other form will 5 answer the purposes of "my present invention. In theform of my invention shown in Figs.

formed on the upper side of one of-two jaws book holder or clamp, the said jaws and the carbon sheet holder beingsubstantially par- Each of the jaws F'is provided with a pieces pass through slots for openings H,

tuting' a fulcrum, through the aid of which the jaws may be pried open or spread apart to receive the leaves or book between them,

by pressing the levers or thumb pieces together. 4

As shown more clearly in Figs. 2 and 3, the

tube or sleeve I is split or divided along its forward side, preferably on a line diametrically opposite a point intermediate of the. slots or openings H, thus forming twospring lips, the lower one of which bears against the under side of the lower jaw F, while the upper one bears upon the upper fold of the carbon sheet holder. In this manner, thespring sleeve notonly forces the jaws together with sufficient pressure to hold the leaves together and to, secure the carbon .lsheet ,holder Lin place, but, owing 'to'the' impingement of the upper fold of the carbon sheet holder bythe upper edge or lip of the spring sleeve, the sides or folds of such carbon sheet holder are .7 i 1 to e inclusive, which willfirst be described, the carbon sheet holder 13 is secured to or firmly squeezed against the carbon and the blade D; thereby holding the blade in place without the employment of other means, such as a catch or latch.

As shown by the dotted lines in Fig. 1, the

jaws F are substantially the same in length being withdrawn in one direction, while their withdrawal in the opposite direction is pre-:

vented by means of a rib J formed on the lower jaw and against which the edge of the sleeve impinges in case the jaw should become slightly displaced, and thereby holds: the jaw against further displacement. The: carbon sheet holder B is here shown as se-;

cured to the upper jaw, but' I wish it to be understood that it would not involve a departure from my invention to form such jaw and carbon sheet holder integrally.

' In the form shown in Figs. 5 to 7 inclusive,

the carbon sheet holder, 13', is of the form shown and described in my aforesaid Letters- Patent, but which is provided in this instance I at its rear edge with a longitudinal bar or loop K, preferably extending throughout the length thereof and being secured at its ends to the ends of the carbon sheet holder, in any suitable manner; and by means ofv this bar the carbon sheet holder is hinged or yieldingly secured to the book holder or clamp in such a manner that the carbon sheet holder will be capable of shifting longitudinally independently of the book-holder, or turned backward over the book-holder when it is desired to turn over a new leaf or to remove the carbon from the writing surface for any other purpose. As a simple means of accomplishing this desirable result, I simply pass the bar or strip K through the book holder between one of its jaws F, the upper one, and one of the spring lips, formed by the split sleeve 1'. Thus, it will be seen that the jaws of the book-holder may be readily opened and closed without interference from the carbon sheet holder; and furthermore, that the carbon sheet holder may be readily shifted from side to side throughout a considerable range, in case the book or leaf being written upon, should be of greaterwidth than the carbon, and that when it is desired to expose a new leaf to the face of the carbon, the carbon-holder may be readily folded backward over the book-holder without disturbing the latter. In this form, the spring sleeve I is provided preferably at its upper and lower sides with spring tongues or pawls L, whose lower ends are turned toward the levers or thumb pieces G and are sharpened and engage in cavities or indentations m, formed in the upper and lower sides respectively of the upper and lower jaws F thus preventing such jaws from being withdrawn from the split sleeve without first disengaging such tongues. The upper edge of the sleeve, in this instance, of course, finds itbearing upon the top of the upperjaw, the rib J being omitted.

Instead of securing a separate bar as the shown in Fig. 8, or throughout its entire length,

like the bar K, in Fig. 5.

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

1. The combination of a removable clamp for holding the book, and a carbon sheet holder secured thereto and being capable of longitudinal movement independently thereof, substantially as set forth.

2. The combination of a removable clamp or book-holder for holding the book and a carbon sheet holder longitudinally movable independently thereof and being hinged thereto and movable bodily independently thereof whereby said carbon sheet holder may be folded backward over the book-holder or adj usted to the book independently of the book holder, substantially as set forth. I

3. In a combined carbon sheet holder and book holder, the combination of a carbon sheet holder having a longitudinal bar or loop, and a removable book holder having a portion engaging said bar or loop, for yieldingly connecting the two together, substantially as set forth.

4.. The combination of the carbon sheet holder provided with a longitudinal loop or bar and a book holder having the jaws F and spring sleeve I, between which spring sleeve and one of said jaws said bar passes, substantially as set forth.

5. The combination of a book clamp consistin g of a divided spring sleeve or tube hav ing slots or openings in its rear side, the jaws arranged in said tube and having thumb pieces or levers projecting through said slots, and a carbon sheet holder connected to one side of said book clamp, substantially as set forth. I

6. The combination of a divided spring sleeve or tube having slots or openings in its rear side, two flat jaws arranged in said tube and being impinged by the edges thereof, and having levers or thumb pieces projecting through said slots on openings respectively, and a carbon sheet holder secured between one of said jaws and one edge of said tube, substantially as set forth.

7. The combination of a divided spring sleeve or tube having spring tongues and openings in its rear side, jaws arranged in said sleeve and being impinged thereby, and" having cavities in which said tongues engage, and thumb pieces or. levers projecting through the openings in said sleeve, and a carbon sheet holder securedbetween one of said jaws and said sleeve, substantially as set forth;

8. In a combined carbon sheet holder and Witnesses: book holder, the combination of a clamp having' spring actuated jaws adapted to be re- 'movab1y' secured to the} book and, a carbon 10 sheet holder hinged to said'clarnp onan axis extending lengthwise of the carbon. sheet holder and adapted to be folded vback over one of said jaws, substantially as set forth.
