Show t-it ri miT -y j-f INVENTORS BARRED OUT. Onlf Tlying Machine That Have Been Perfected Per-fected Will lie Patented. We hear a great deal from time to time in regard to new inventions which are coming out for the purpose of enabling en-abling a man to fly, either from efforts of his own or through the intervention of stoam engines or other motors. It is interesting to note the attitude which the United States patent office has taken in regard to such inventions. They practically prac-tically destroy all claims for flying machines ma-chines beforehand, and the following is an abstract from what is practically a circular letter sent out to all attorneys who have made application for flying machine patents. It reads as follows: "On taking up this case for examination examina-tion it is found that the invention disclosed dis-closed thereby is, as a whole, incapable of practical operation, since without the assistance of gas, field or equivalent the device will be incapable of ascension. ascen-sion. In other words, it is not useful within the meaning of the law. "No evidence will be considered sufficient suffi-cient to demonstrate the operativenesa of the device and warrant the withdrawal with-drawal of the objection made by the office except a working model that is, one with which it is possible to actually ascend as-cend and direct the course of flight at wilL " Tims it is practically useless for any inventor to make an application for a patent until he has actually succeeded in flying. It it barely possible that such a stand as this in regard to certain inventions in-ventions would not be amiss, as there are more impracticable ideas patented than the world at large have any idea of. While it may be considered as a hardship by flying machine inventors that they are debarred from the protection protec-tion of the patent office, yet until they have actually produced something which will accomplish the results claimed they certainly have no right to overlap the claim of protection on the patent office.
