But neither the specification nor claim of the Olmstead patent mentions, as a part of the process, the cooling of the wax or paraffine coating before compressing it upon the wire. The appellant's counsel, however, contends that it must be considered a part of the process, because the polished appearance of the surface of the covering described in the specification is the result of allowing the paraffine or wax to cool before compressing it upon the wire. But, clearly, a patentee cannot claim the benefit of an element of his invention thus vaguely and indefinitely hinted at.

The patent of Baudouin describes his process as follows: 'My invention relates to the preparation of conductors of electricity for electric telegraphs, being wires insulated to prevent the loss or deterioration of the electric currents used for that purpose, and also in the machinery for the preparation of manufacture of such conductors. I coat the wires with bituminous or such like fatty matters that are not liable to become hard or crack, but, on the contrary, are constantly acted on by the temperature of the atmosphere.

The coated and lapped wire passes through dies or smoothing holes both in entering and leaving the rotating frame. These dies or smoothers have a rotary motion, the better to enable them to wipe and smooth the coated wire.'
It is plain that these patents anticipate the process set out in the specification of the Olmstead process patent. They all three describe the compressing of the wax, paraffine, or bitumen coating of a wire covered with the fibrous material, so as to attain the same result, namely, the insulation of the wire.
