Description

UNITED STATES PATENT OFFICE.
EDWARD D. JOHNSON, OF LOS ANGELES, CALIFORNIA.
TYMPAN-SHEET.
N Drawing.
To all whom it may concern:
' tion of the below named ingredients and the T pressmans sheet treated with same.
The object of my invention is to protect the blankets and rubbers used by pressmen and to prevent off-setting.
A further object is to provide a sheet for the use of pressmen, which will not readily absorb the ink, causing them to soften and to disintegrate, with use.
Owing to the length of time, which sheets prepared with my composition, can be used, they are very economical. The saving of material in the sheets themselves is an important item and much time is saved in the less frequent changing of the sheets, than is required at the present time.
My composition consists of the following ingredients, combined in the proportions stated, viz.: linseed oil one gal, oil of ce- Specification of Letters Patent.
Application filed September 8, 1910. Serial No. 581,121.
Patented Jan. 24, 1911.
dar one half 02., japan drier one half gill, litharge one half gill. After thoroughly mixing these ingredients, the material used for the sheets, which consists of ordinary muslin, is immersed in the compound; and when the surplus is drained from the muslin, the latter is hung in a convenient place for drying. This will occur in a comparatively short time, giving a heavy body and a hard surface to the sheets.
WVhen sheets are prepared in this manner they will not absorb moisture readily and will not become saturated with ink as readily as other sheets now in use, do.
Having described my invention what I claim as new and desire to secure by Letters Patent, isl The herein described composition for treating tympan sheets, consisting of linseed oil, one gallon, oil of cedar one-half ounce, japan drier one-half gill and litharge onehalf gill, substantially as specified.
In testimony whereof I afiix my signature in presence of two witnesses.
