IMPROVEMENT lN MOUNTINGS FOR SHOW-CARDS.
Specification forming part of Letters Patent No. 126,885, dated May 21, 1872 antedated May 4, 1872.
This mode of mounting is expensive, and the show-cards are liable to warp and twist by atmospheric changes. To remedy these difliculties, and to avoid the expense of frames for show-cards and other articles are the objects of my present invention.
'I introduce between two sheets of Manila or otherstron g paper, a plastic com position, forming the body of the card, which composition will 'dry or harden. The sheets of paper on each side will prevent the composition cracking by use, and a flat, cheap body will thereby be formed for the reception of the showcard or other article; or the show-card, orthe paper of the same, may form one of the sheets between which the composition is introduced.
In the drawing, a section is shown of the said mounting, the sheets of paper a b being on opposite sides of the plastic composition 0.
I prefer and make use of plaster of Paris in the proportion of about one part of the former I to thirty-two parts of the latter, as the material for the plastic mass but if this alone were employed, the plastemwould set and harden too rapidly, and would bevery brittle. I have discovered that ground althea root mixed with plaster of Paris Will prevent the same harden in g rapidly, and will increase the strength thereof, and this compound may be used for other purposes when plaster of Paris is available.
I find that by applying this composition between sheets of paper as they are drawn through between rollers auniformity of thickness will be produced, and two long webs of paper may be employed, and the slabs cut up into the proper. size, or else separate sheets may be,used. These slabs or sheets should be piled upon each other, so as to be flat while drying or hardening, and additional pressure may be used to keep the parts flat. The showcard, picture, or other article is to be applied to the surface and finished in any desired manner.
In this construction the show-cards will remain flat. There is no tendency to warp and twist, even when one side only is exposed to the light. They willpack'into as small a space as those mounted on mill-board,,and they will not be liable to be broken, torn, or twisted like show-cards mounted on frames and stretchers. If desired, rings or hooks d may be applied at the back while the composition is soft, so as to embed themselves in the paper and form their own recess; thereby the show-cards will pack flat when put up for transportation. In
" this case the ring or hook will be held in place by a wire eye, the ends passing through the paper into the composition, as seen at e. It will be seen that, by placin gthese wires through the paper so as to attach the rings or hooks thereto before running the sheets and composition through between the rollers, the ring or book will embed itself and form its own cavity.
I claim as my invention- 1. The mounting for show-cards and other articles made of two thicknesses of paper, with the intervening body of plastic material, sub
stantially as set forth.
2. The rings or hooks pressed into the paper and plastic material, and forming their own recess in the mounting, as set forth.
3. The plastic composition made by mixing ground althea. root with plaster of Paris, for the purposes set forth.
Signed by me this 8th day of September, A.
