Be it knownthat I, ALBERT I a citizen ofthe United States, andresident State ofNew York, ha-ve invented a new anduseful Improvement in Stencils', of which the following is a specification.`

Heretofore'in the manufacture of stencils in which a suitably prepared -long fiber fabric hasbeen employed, the fabric has been secured tov its oblong frame and stretched 'across the opening therein with thefibers running transversely of the frame,

-,namely, across the narrow gap therein. As

the long fiber fabric, due'to its 'method of manufacture, is much stronger in the divfully the very hard usage tofwhich rection in which the fibers run than in the direction across the fibers, itfhas beencustomary in manufacturing stencils to make the fabric in two or more plies soafs to give sufficient strength" for withstanding successcils are ordinarily subjected. .-1

vI have discovered hat by securing the long fiber. fabric to the oblong framewith the 4fibers running longitudinally ofA thef frame, I am enabled to obtain'tlge. greatest strengthvin the direction needed, and-by doing this I am'en'abled` to make a very strong and durable stencilwithonly a single ply ofthe long-fiberpfabric, which it has heretofore been impossible to do, thus saving ma-y terially in' the cost of the vstencil and inthe expense of manufacturing thesame. `I also produce a stencil in which Atheqmatter pressed thereon by the typewriting machine I will 'not'become distorted but will be trans` ferred in the' stencil addressing machin very accuratelyand clearly because of valuable for the purpose intended.
