William Blackburn from Manchester, Great Britain, received a British patent for an improved school desk. Patent no. 127839 was issued on June 11, 1872.
This desk is made of a combination of wood and iron and can be used as a desk or a table. The adjustable design allowed the desk to be used in schools or places of assembly. The desks adjust with the use of metal hinges. The backrest is made up of slats that do not connect for lower back support, is made of darker wood than the seat, and is polished. The desk sits on a metal base of two long feet that connect each side’s back and front.
We are not aware of any additional information about the inventor/patentee.
This model was submitted to the U.S. Patent Office with the application for the patent issued to John Robinson and James Gresham, of Manchester, England, May 29, 1866, no. 55218.
The feature of this injector is to provide a means of varying the area of the annular space through which the water enters the combining tube for the purpose of properly proportioning the steam and water supplies. The combining tube is made free to slide in the direction of the axis of the tube and is adjusted by a hand wheel at the side of the injector, the shaft of which projects into the injector and carries a small pinion that meshes with a short rack formed on the tube. Packing around the sliding tube is dispensed with by forming the tube in two parts, a fixed part and a sliding part, and proportioning the two parts so that the ends of the sliding part will be “opposite that part of the passing current where it has attained its highest velocity; and by this arrangement the passing liquid has no tendency to escape but rather to draw in air or fluid.”
