My invention consists of an improved process'for manufacturing rubber-coated harnesstrimmirigs. There are three principal operations which form the combined process which is the subject-matter of this specification:
First, the preparation and application of the coating to the metal; second,-the vulcanization ot' the coating; third, the'compressing The metallic ring, buckle, terret, or other article to be coated is first. carefully cleaned by washin g and drying until freefrom dust or' which might prevent a ien feet adhesion of the coating; This coating may .be of rubber, gutta-percha, or other known vul- V canizable gum properly preparcd'for vulcanization. i I
I have attained the best results with the following process: I first take a good quality of the rubber and sulphur composition commonly used, consisting of about two parts of rubber to one part of sulphur. This composition of stiff dough, paste may be thinner. I then apply a thin coatingot' the coin1,) osition-'-wl1ich is easiest done when rolled into sheets of uniform thickness-to the article, working and pressing itv firmly to the metal by the hand or otherwise.
The article thus eoated'with the vulcanizable gum is then placed in a mold of the proper shape, so as to keep the coating in due thickness and proportion; or the articles maybe packed in stone-dust or plaster, as usual, with about equal to that although the composition orv other. rubber goods. The articles in theirmolds or packing are then placed inthe vulcanigingoven, and remain in the usualrulcanizing temperature from six to ten hours, until sufiiciently hardened. After being'thns vulcanized the articles are ready for theaction of the dies;
The dies to be used in this process should be a very little smaller than the irtic'le to be pressed, so that they may thoroughly compress and density the coating upon the. metal. They should have cutting-edges-s'o'as to shearotf the superfluous-coating, and should be providdies are'more fully describedin Division A of this specification.
