PATENT JAMES BARKER, OF DETROIT, MICHIGAN.-

TRIAL OI? DAILY BALANCE SHEET.

SPECIFICATION forming part of Letters Patent No. 681,431, dated August 27, 1901.

Application filed October 15, 1900. Serial No. 33,102. (No model.)

To 0/. whom it may concern.-

Be it known that I, JAMES BARKER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan,have invented certain new and useful Improvements in Trial or Daily Balance Sheets, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to trial or daily balance sheets of that class wherein the leaf-surfaces are composed of detachable tablets of silicate or other similar material, from which written matter may be readily erased to allow of any individual balance being changed or altered independently of the others or to permit the removal of one or more of the tablets for the purpose of renewal.

Heretofore it has been the practice to employ raised guides of metal or other material as the securing means for the tablets, the guides being arranged in pairs upon the opposite faces of the leaf and secured to the latter by fastenings extending through the leaf or connected to a frame extending about the edge of the leaf. As thus formed the leaf has been found objectionable in use, first, because the structure is complicated, cumbersome,'and expensive to manufacture, and, second, for the reason that the raised guides in addition to forming obstructions upon the leaf-surfaces occupy considerable space and materially decrease the available writing surface of the sheet.

The object of my invention is to produce an inexpensive leaf or sheet of the type referred to of simple formation, the tablets of which will be so connected to the leaf-body as to produce a smooth, even, and uninterrupted face, the entire surface of which will be available for writing.

With this object in view my invention consists in the peculiar formation of the leaf, as will be more fully hereinafter described, and shown in the drawings, in which- Figure l is a perspective view of a trial or daily balance sheet embodying my invention. Fig. 2 is a section taken on liners m, Fig. 1. Fig. 3 is an end elevation of one of the tablets. Fig. 4 is amodification of the sheet.

In the drawings thus briefly referred to the reference letter A designates a leaf-body formed of stiff material, such as cardboard, and having a plurality of recesses B, formed therein, extending entirely across the sheet.

The sides of the recesses are undercut, form:

ing guideways, such as O, and D represents the tablets arranged within the recesses re-: ferred to and having slides E thereon, which engage the guideways. The slides referred to are composed of strips, such as F, preferably glued to and extending centrally along the under face of each tablet, and a second strip G, secured to the strip F and projecting beyond the sides of the latter, as shown.

The removable surface of the leaf has been shown as composed of three tablets arranged in the manner indicated. It will be obvious, however, that the number of tablets may be increased or decreased as may be desired.

The grooves or recesses in the sheet-body are so formed that when the tablets are arranged therein the meeting edges of the tablets Will abut, thus forming a smooth and uninterrupted facing for the leaf, the entire surface of which maybe written upon.

In Fig. 4. I have shown a leaf provided with recesses for the tablets upon its opposite faces, and in Fig. 1 I have illustrated means whereby the sheets may, if desired, be bound together to form a book. The means consists, preferably, of a binding-strip, such as H, and a hinge 1, connecting the strip with the leafbody and permitting the latter to be readily turned. I have also provided means for preventing the curling of the tablet-edges, so that the upper faces of the tablets will always lie in the same plane, producing the even continuous surface desired. The means referred to comprise strips J, of any suitable material, which are arranged upon the under face of each tablet at its opposite edges, as plainly shown in Fig. 3.

While I have shown a particular type of connecting device for detachably securing the tablets to the leaf-body, I do not desire to be limited to the same, as other connections could be employed without departing from the spirit of my invention.

What I claim as my invention is 1. A trial or balance sheet for loose-leafledgers, comprising the leaf-body, a removable writing-surface entirely covering one of its sides, said surface being composed of a ICO single series of abutting and uninterruptedlyextending tablets of uniform thickness, and a detachable connection between each of the tablets and the leaf-body, whereby any one of the tablets maybe removed independently of the others. i

2. A trial or balance sheet for loose-leaf ledgers, comprising the leaf-body, a removable writing-surface entirely covering one of its sides, said surface being composed of a single series of abutting tablets extending uninterrnptedly over said sides and being of the facesof the tablets adjacent the body at the opposite edges of the tablets, substantially as described.

4. A trial or balance sheet for loose-leaf ledgers consisting of the leaf-body, a bindingstrip therefor adapted to be connected to the ledger, and a removable Writing-surface extending from the stripacross the body and entirely covering one side of the latter, said surface being composed of a single series of abutting tablets of uniform thickness, each detachably secured to the body and the series extending uninterruptedly thereover, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES BARKER.
