DETACHABLE BACKING FRAME 0R CASE FOR DRAWING-TABLETS.

SPECIFICATION forming part of Letters Patent No. 391,602, dated October 23, 1888.

Application filed April 6, 1898. Serial No. 269,894. (No model.)

To aZZ whom it may concern:

Be it known that I, BER'll-IA E. FORBRIGER, a citizen of the United States, residing at Gincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Detachable Backi n g Frames or Cases for Drawing-Tablets, Musicliooks, 800., of which the following is a specification.

My invention relates to a removable covering frame or backing for drawing tablets, whereby the several sheets composing the same are kept clean and intact and the work done on them preserved in proper condition for future reference from lillIlG to time; and my invention consists, in the first part, in the provision, in connection with a drawing-tab let composed of a number of specimen or eX- ercise working-sheets, of a removable case or backing frame made of any suitable textile fabricsuch as colored muslin, or the like turned upwardly and inwardly at its edges to encompass or engage the outer edges of said tablet, and having a tightening cord or tape at its inner edges to (.letaehably secure it in place.

My invention further consists in the provision, in connection with a drawing-tablet and the aforesaid removable backing frame or case having a draw-string or tightening-cord, ofstiff metallic split rings or fastening hingeeyes in one end of the tablet loosely binding its several sheets together, so that each top sheet can be turned back thereon and folded against the bottom sheet after an exercise or specimen figure has been copied and the sheet completed, and also receiving and holding the drawingpencil, crayon, or writing-pen when not in use.

Other features of my invention will be fully set forth in the following description of the accompanying drawings, in which- Figure 1 is a plan view showing my invention complete in its preferred form 5 Fig. 2, a longitudinal section on line 0000, Fig. 1; Fig. 3, a detail perspective View of my improved tablet, showing one sheet elevated and in the act of being turned back on the bindingeyes to the bottom of the tablet; Fig. 4, a modification shqwing a full-size broken plan of one corner of the tablet and its case or backing frame when the latter is provided with an inelastic tape, which is drawn and tied at the upper edge; and Fig. 5, a plan of a music-book with my improvements applied thereto.

A represents an ordinary drawing tablet or sketch-block composed of a number of leaves or exercise-sheets upon which the pupil draws. Such sheets may be blank ones and used by an artist or draftsman, or they may be provided with writing-exercises for the student, as is obvious.

I prefer to independently or loosely connectthe several sheets of the tablet together,so that they may be readily separated and hinged or turned back in succession, the finished top one with its face against the back or bottom of the lowermost one, and operated as shown by the arrow in Fig. 3. This I accomplish. by means of the stiff metallic split eyes or fastening-rings a a, (more clearly shown. in Fig. 2,) which areinserted in openings a in said sheets. The projecting portions of the eyes or rings a furnish a suitable receptacle for the drawingpencil B, as shown in Figs. 1 and 2, when not in use.

0 represents a backing frame or case, into which the tablet A is inseated, the outer edges of said backing-frame being turned upwardly and inwardly to overlap theseveral outer edges of said tablet, and the whole detachably secured in place by means of a cord or tape, a, lying within a hem on the inner edges thereof.

The backingframe O is made of any suitable material, but preferably of colored muslin, slit or mitered at its four corners, to fit properly in place on the tablet and at the same time present a neat appearance. The upper end of case 0 is provided withslots or openings D for accommodating the projecting portions of the hinge-rings a a on the tablet.

The tighteningcord c, for detachably securing case (J on the tablet, is preferably an elastic one, and thereby facilitates the attachment or removal of said case when it is desired to turn a sheet back for another lesson or to remove the tablet altogether, to be replaced by a new one. 7

In Fig. 4 I have shown how I construct the backing-frame when an ordinary inelastic cord or tape is used for securing it in place. A central opening, I), is made in its hemmed edge,

and the ends (1 dof the cord drawn outwardly and there tied in a bow, or otherwise suitably fastened.

In the use of my backing-case asupplemental bottom and an edging shield or protector are provided for the tablet, leaving an open working-sight on its face, and said case effectually preserves the several sheets, and particularly the finished ones, intact against soiling, rupture, or other damage.

My case or backing and hinge-rings may also be used in connection with sheet-music, as shown in Fig. 5, the inner edges of the several sheets being connected together by said hingerings which allow them to lie flat when open and in use.

Suitable openings are made in the backing, as shown, for the accommodation of the projecting parts of said binding hinge-rings.

I claim 1. A removable protectingoase or backingframe for a drawing-tablet or other matter in sheet form, composed of the backing frame or case 0, having its edges upwardly and inwardly turned and provided with a tightening-cord, c, the whole engaging the several outer edges and backs of said tablet or other sheet matter, substantially as and for the purpose specified.

2. The combination, with adrawing-tablet or other matter in sheet form, A, and a removable backing frame or case, 0, the latter being provided with atightening-cord or drawstring, c, and slots or openings D, of stiffrings or eyes a a, loosely uniting or binding the upper ends of the several leaves or sheets of said tablet together and projecting through said slots or openings D in the backing-frame to form a convenient and safe receptacle for the drawing-pencil or Writing implement, substantially as herein set forth.

In testimony of which invention I have hereunto set my hand.

BERTHA E. FORBRIGER.
