Granville Woods' brother, Lyates Woods, is credited with uniting with Granville in the joint invention of several machines. Most of these consisted of electrical apparatuses, but two of them seem to have been of sufficient importance to attract the attention of such corporations as the Westinghouse Electric Company, of Pennsylvania. Patents No. 775,825, of March 29, 1904, and No. 795,243, of July 18, 1905, both for railway brakes, were assigned by the Woods brothers to this company. The record shows that the American Bell Telephone Company purchased Woods' patent No. 315,386, granted April 7, 1885, for the latter's invention of an apparatus for transmitting messages by electricity. The same inventor sold to the General Electric Company, of New York, his patent No. 667,110, of January 29, 1901, on his invention for electric railways. We should mention here also two other inventors of importance in the line of appliances for musical instruments, Mr. J. H. Dickinson and his son S. L. Dickinson, both of New Jersey. They have been granted more than a dozen patents for their appliances, mostly in the line of devices connected with the player piano machinery. They are still engaged in the business of inventing, and both are holding responsible and lucrative positions with first-class music corporations. The inventions of W. B. Purvis, of Philadelphia, in machinery for making paper bags are reported to be responsible for much of the great improvement made in that art; and his patents, more than a dozen in number on that subject alone, are said to have brought him good financial returns. Many of them are recorded as having been sold to the Union Paper Bag Company, of New York. Another instance is that of an invention capable of playing an important part in the cotton raising industry. This was a cotton-picking machine covered by two patents granted to A. P. Albert, a native Louisiana Creole. Mr. Albert invented a second machine which is said to have the merit of perfect practicability, a feat not easy of accomplishment in that class of machinery. Special significance is attached to this case because of the inventor's experience in putting through his application for a patent. He was obliged to appeal from the adverse decision of the principal examiner to the Board of Examiners-In-Chief, a body of highly trained legal and technical experts appointed to pass upon the legal and mechanical merits of an invention turned down by the primary examiners. Albert appeared before this Board in his own defense with a brief prepared entirely by himself, and won his case through his thorough painstaking presentation of all the legal and technical points involved. Mr. Albert is a graduate of the Law Department of Howard University in Washington, and is connected with the United States Civil Service as an examiner in the Pension Office.
