WHEN hard rubber stock in a plastic condition is pressedbetween comb forming dies of the usual construction, itis impossible to force by pressure from between the diesall of the material not required in the comb. This is one of thereasons why so few rubber combs have been formed entirely bystamping out in dies, with the comb teeth completely formed bya single Fig. 1. \\iei.,\.nds H.\ri) Rubber Dies. In an invention of F. , the stock is pressed betweendies arranged to form a comli blank, in which all of the teeth arcpractically of the desired linal shape and size. The superfluousstock that remains between the teeth and at the ends and sides isconnected to the comb by thin webs which are easily broken to the accompanying drawings inconnection with the following description willgive an idea of the construction of these diesand the manner in which the comb is formed. In Iig. 1, A is a plan view of the lowerhalf of the die and B is a partial cross sectionand part exterior view of the upper and lowerhalves. C shows the shape of the rubber blankafter it has been pressed and removed fromthe dies and D is a cross section of the sameblank. The dies are formed so that when thetwo halves are placed together, spaces F are<eft for the teeth. Between these spaces aresmaller spaces E, which receive t
