Student Designs Gold Ore Machines

1915

Big Saving in Ore Refinement May Be the Result

New equipment for use of the seniors of the University of Washington, which was designed and is being built under the direction of Fred Porter, a senior will soon be installed, and with it the men will perform a series of experiments of great practical and economic value.

Two complete sets of machinery have been designed by Porter for use in fine grinding and concentration of gold ore, some of the equipment being of the same style as has been used in the Alaska, Idaho and Montana gold fields in the last few years for the purpose of experimentation. The experiments to be performed may, besides being the work necessary to constitute the thesis required to gain a degree, result in a large saving in the refinement of ore.

One of the processes to be performed will be that of flotation concentration. the process discovered by Mrs. Everson, described in these columns last week.


Plan to Interest Mechanics

Use Inventor's Tools and Gain Equity in His Patents

William L. Bessola, an experienced mechanic known to practically every one connected with mechanical departments of mines in Minnesota, Wisconsin, and Michigan, and who holds patents for many mechanical devices, is endeavoring to interest capitalists and others in a proposition the success of which is assured.

As a forerunner to the manufacture and of the perfected tools on a large scale it is the plan of Mr. Bessola and his associates to secure the cooperation of every user of tools that they seek to replace with the new inventions, and to this end they have permitted a number of the leading plumbers, master mechanics and men generally connected with things mechanical, to purchase equities in the exploitation company, which not only entitles them to substantial interest in that direction, but also secures for each a proportionate right in the patents which Mr. Bessola has taken out.
