Engraved Pressing Roller for the Guidance of Bees in the Construction of Honey-Comb on the Bars
This is an engraved metal roller, which, when applied to the coated underside of a comb-bar, leaves an impression as shown in the diagram. The wax having been spread on the flat bar, the roller, heated by being put into hot water, is heavily pressed over it. The roller has two wooden handles, so that considerable pressure may be given to it. The roller is a little less than two inches in diameter, seven-eighths of an inch wide, and the length from handle to handle is six inches. The diagram shows the full size of the impressions as left on the wax, after passing the roller along the comb-bar, in the manner above described. It is a contrivance invented in Switzerland, and exhibited in the International Exhibition of 1862, when the pattern roller was purchased by ourselves.
The bars of a hive prepared with these markings in wax afford ready-made foundations for regular combs, which very much facilitate the operations of the bees.
