Abstract
Abstract This specification discloses a coating process for articles of manufacture which uses an open hollow head and a diaphragm stretched across the opening. The diaphragm has embossed on it the pattern which is to be coated on the article. Air pressure forces the diaphragm into engagement with a coating plate. The diaphragm is then drawn up into the head. The coating plate is removed and replaced by the article to be coated. Air pressure forces the diaphragm into engagement with the article thereby coating the pattern on the article.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
273 words
An apparatus for coating an article of manufacture comprising, a lower box having a relatively flat bottom and spaced sides extending upwardly from said bottom defining an open topped enclosure, an article nest supported on said bottom, a relatively flat pattern plate having an aperture therein adapted to be removably supported on the upper edge of said lower box, said pattern plate adapted to be inked, an upper box closed at its top and having downwardly extending sides, extending downwardly from said top, a flexible diaphragm having a pattern formed thereon attached to said sides of said upper box, means to introduce air under pressure in said upper box behind said diaphragm, means to introduce a vacuum into the space behind said diaphramg in said upper box, means to move said upper box down to bring its sides into engagement with the upper edges of the sides of said lower box, and sealing means for forming a seal between the engaging edges of said boxes, means to admit gas under pressure into the space in said upper box behind said diaphragm and to move said diaphragm into engagement with said pattern plate when said pattern plate is supported on said lower box, and means to move said upper box upward from said lower box whereby said pattern plate can be removed and said upper box can be moved into engagement with said lower box and said diaphragm with said inked pattern thereon can be forced downward into engagement with said article supported on said article nest, and vaccum means in said lower box for drawing said diaphragm into tight engagement with said pattern.
