CHARLES F. MUTIER, OF BUFFALO, NEW YORK.

BACK FOR PICTURES.

SPECIFICATION forming part of Letters Patent No. 358,058. dated February 22, 1887.

Application filed July 21, 1886. Serial No. 208,615. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES F. MUTrER, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements on Backs for Pictures, 850.; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertaius to make and use the same.

My present invention has general reference to backs for pictures, &c.; and it consists, essentially, of the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, then pointed out in the claim.

In the drawings already referred to, which serve to illustrate my said invention more fully, Figure 1 is a perspective view of a back constructed in accordance with my invention. Fig. 2 is a side view of the same. Fig. 3 is a plan.

The object of my present invention is the production of a durable, cheap, and well-look-' ing back for pictures. To attain this result, I construct my picture backs of a series of boards of sufficient thickness and suitable width. These boards A A A, I then secure together across their abutting joints by means of narrow strips of cotton or other suitable fabric glued to the said boards, and on the opposite side by a sheet of Manilla rope or other proper and strong paper. The object of thus gluing a sheet of the paper described is to convert the otherwise usually rough and unsightly-looking board into a good-looking surface having approximately the appearance ofaplaned pine board, said Manilla rope pa per being of such a color and owing to its tenacity and durability well designed to hold the boards together. The strips of cotton B are glued over the longitudinal joints of the several pieees'composing the back. They are cut somewhat longer than the length of the joint to be covered, so that the surplus length may be folded over the edge of the pieces of board and onto the opposite side, as shown at D, where the pieces are glued upon either the side of the board previous to its being covered with paper, or, preferably, before the said paper is applied, so that the paper will cover the textile fabric and present an undisturbed and level surface.

By having the textile fabric pass around the edges of the boards I derive an advantage not to be attained by any other method of procedure, which is that the joints cannot readily be torn apart, the cloth on said edges forming, as it were, a selvage, which cannot be disturbed without considerable effort.

Instead of turning the textile fabric over onto the side opposite to where it is applied, I may double the same on the edges of the boards to form a so-called selvage, and thereby obtain nearly, though not quite, the same results as those obtained by the method described. Such a construction is shown at E, Fig. 1, and is considered an equivalent of the method heretofore described.

Heretofore, backs for pictures have been produced by gluing sheets of paper on both sides of the boards. This construction, though practically serving a good purpose, is yet objectiouable, owing to the fact that, especially in large backs, the gluing of the paper on both sides is very expensive, while at the same time it does not afford that degree of strength to the jointed pieces that is necessary and desirable'for large and valuable pictures. This objection is entirely overcome in my invention, and at the same time the cost of production reduced to quite a degree.

Having thus full described myinvention, I claim as new and desire to secure to me by Letters Patent of the United States An improved article of manufacture, consisting of a series of contiguous strips forming a plate, one side of said plate being provided with a paper facing secured thereto by an adhesive material, the joints on the other side of the plate being provided with and covered by strips of fabric, the ends of said strips eX-
