Henry Orford (NB!)    30 January 1909           Manufacture of Lenses for Spectacles and Eye-Glasses        Ref G02C7/02

                                                                               Taken out in his first names, with no mention of "Gowlland"; and

                                                                  with one-half assigned to an American Samuel J Taylor, this is his

                                                                  first description of a lens with one spherical surface and one parabolic.

                                                                  There is no indication of how he proposes the moulded surfaces be

                                                                  ground, smoothed and polished - presumably he had not reaches that stage.

                                                                  Note that throughout he uses, and signs, the name "Henry Orford".




Henry Gowlland        1st September 1914      Improvements in or relating to Lenses for Spectacles etc        Ref

                                                                This appears to be the first patent mentioning cutting of the lenses,

                                                                and is useful in establishing what Henry was trying to achieve.


Henry Gowlland        3rd March 1915              Smoothing Head for manufacturing eye-glass lenses                Ref B24D13/16

                                                                This patent of Henry's covers a smoothing head able to conform to a

                                                                face with more than one curvature.                                                               


Henry Gowlland        9th October 1915            Lens grinding machine                                                                    Ref B24B13/005

                                                                This patent covers a means of grinding the initial multi-focus

                                                                lens, the surface then being finished using the machine above.


Henry Gowlland        7th December 1916    Smoothing Tools for use in the manufacture of Lenses                Ref B24D13/142

                                                                This appears to be a refinement of the 1915 patent

William Gowlland        29th June 1896        Improvements in and connected with Means for the utilization             GB189614375(A)

Charles Gowlland                                          of Acetylene Gas in Motors and Ordnance, and for producing

                                                                        explosions, and for other purposes.

                                                             This patent William enquired about in 1943 as he insisted his ideas

                                                            had been used by Barnes Wallis in his bouncing bomb used in the

                                                            Dambusters' raid.  See Melissa Gowlland's letter to Geoff dated 25th May

                                                            1943 - click here.  As she comments, "Quite mad, of course!".



William Gowlland        30th June 1896    Improvements in or relating to Fluid-pressure Motors                        GB189614446(A)

Charles Gowlland                                Pursuing innovative uses for acetylene, this time for

                                                         obtaining rotary motion - remember this was at the very

                                                         beginning of motor car development.  But generating

                                                         acetylene with water and calcium carbide is very dangerous.

                                                         Tolerable, perhaps, for headlights, but not for anything bigger.                                            



William Gowlland         29th June 1896   Improved Method of obtaining Motive Power from Gaseous            GB189615752(A)

                                                                    Pressure and Apparatus.

                                                                   This patent, filed one day before the similar one above, is

                                                         in William's sole name - no mention of Charles.  Why?  It covers

                                                         both motors and ordnance.  It is so wide-reaching that it seems

                                                         unbelievable that it was ever accepted.


Charles Gowlland    7th September 1944    Improvements connected with cloche clips                                    GB563984(A)

                                                              It would seem he had time on his hands!  Certainly there

                                                              seems to have been no commercial interest in these.
