 | A transcript of the letter 
				on the left, that was written by Thomas Wheatley Parker, and 
				sent to his grandson Charles Parker, in June 1889. It describes 
				Thomas Parker’s early career: Your 
				father left home when he was about 18, and after working and 
				tramping about the country for several years, came to work by me 
				on the 2nd
                  December 1867. Went to the lower works on the 26th August 
				1868, left on the 10th October, 1874, went to Birmingham on the 
				13th and to the old Union Mills 
				on the 14th. Left on the 21st
                  April, 1875, began again at Coalbrookdale on 3rd May 1875, 
				left on 7th October, 1882, went to Wolverhampton. Your father 
				will be able to judge between the above dates, when he made the 
				lathe and pump and grate. The driving wheel for the lathe was 
				cast on the 4th
                  August, 1868, the day on which Strethill Farm was burnt down. 
				I went to see it, and it could not be cast ‘till I came back. It 
				was cast in the cellar. Signed T. W. Parker |  
            
            
              
                | By 1875 the family had moved to "The Laurels", which was nearer 
				to the Coalbrookdale Company's offices and Alfred and Annie were 
				born there. At the 
					time, the Coalbrookdale Company where producing elaborate 
					stoves and fireplaces, domestic ironware and a rapidly 
					increasing range of rainwater and soil goods, such as 
					gutters, drainpipes and gratings. 
				 The company also produced 
					high pressure pumping engines, and in response to this, 
					Thomas, in collaboration with Philip Weston, invented the 
					Parker and Weston Patent Steam Pump in 1876.
                
				 
              	This was Thomas's first major invention, which was manufactured 
					exclusively by the Coalbrookdale Company and sold throughout 
					the world. Philip Weston was a machinist at the works and he 
					and Thomas took out two patents for the pump. By 
				1881, Philip Weston, who was 52 years old and lived at Woodside, 
				Madeley, had become manager of the iron foundry. 
              	
				 
              	
              	Eight years later they were presented with a medal for the 
					invention, at the Inventions Exhibition in London. This was 
					the first of Thomas’s many inventions to receive any 
					recognition and he attributed this presentation as his real 
					start in life.

						1878, as can be seen from the small section of an

												The Engineer, 
												19th July, 1878. The Paris 
												Exhibition  
												Direct-acting steam pumps are 
												exhibited by several makers, the 
												Coalbrookdale Company making a 
												good show of different sizes of 
												ram and plunger pumps, some 
												fitted with a condenser and 
												others with an arrangement of 
												adjustable cataract, by which 
												the pump may be made to work 
												exclusively through any desired 
												range above half stroke….  
												….The company exhibited some of 
												their pumps in action pumping 
												tar, and capable of pumping 
												pottery slip or slurry; and a 
												direct acting blowing engine for 
												forges, cupolas, and for 
												ventilating. This consists 
												simply of the steam cylinder of 
												the direct-acting steam pump 
												with the pumping cylinder 
												replaced by a blowing cylinder, 
												surmounted by a large air 
												vessel. This, like all the pumps 
												exhibited, is fitted with 
												Messrs. Parker and Weston's 
												patent direct-acting pump valve 
												arrangements. |  |  |   Coalbrookdale in Thomas's time. From an old

				In about 1878 he designed and built a large dynamo for the firm's electro-plating department. The art casting 
				department at the works used electro-deposition of bronze and 
				copper finishes on a large scale.   
				 The electricity previously 
				came from huge battery cells, which would have needed a lot of 
				maintenance and only supplied a limited amount of power.   
				This must have been one of the first dynamos in 
				the country to be put to a practical use, and one the first to 
				be used for this purpose 
				in the world. 
				The Coalbrookdale Company turned its attention to smoke 
				abatement and introduced the Iron Bridge series of grates. 
				
               
				
				Thomas also considered the problem and invented the "Kyrle" open 
				grate, which was the first open grate in which  
				anthracite coal could be burned.

					| The "Kyrle" grate was probably named after John Kyrle, 
					an English philanthropist who lived in Ross-on-Wye, and 
					devoted his life, and his wealth, to the greater good of the 
					community, and the local area. At the time when the grate 
					was developed, the Kyrle Society, founded in 1876 was making 
					a name for itself by bettering the life of working people, 
					and encouraging the development of parks, and gardens. The grate was added to the Coalbrookdale 
				Company's list of products, and in 
                  1881, after official testing by the Smoke Abatement Committee 
				of the International Smoke Abatement Exhibition, at South 
				Kensington, he was awarded the Exhibition's Silver Medal.
                  	 
					At about the same time he invented a gas engine, known as 
					“Robinson’s”. It was made by Tangye Brothers of Birmingham. |

 | In 1859 the lead-acid cell was invented by 
				the French scientist, Raimond Louis Gaston 
				Planté. Thomas began to make his own accumulators, as the cells 
				were called, and began to cooperate with Paul Bedford Elwell, 
				who ran the Patent Tip and Horseshoe Company in Wolverhampton. 
				 
				
				This work led to a patent being taken out in 1882, by Thomas 
				Parker, in conjunction with Paul Bedford Elwell, for an 
				improvement to Planté’s original design, which greatly increased 
				the capacity of the cell. In their process the lead plates for 
				the battery were first put in a bath of dilute nitric acid and 
				sulphuric acid, and left there for 24 hours. The effect of the 
				bath was to minutely honeycomb the lead plates to form what was 
				called "spongy lead".  
				
				This greatly increased the surface area of 
				the plates and hence the capacity of the battery. A deposit of 
				lead sulphate also formed on the surface, which was subsequently 
				reduced to peroxide, and part of this was washed off before use.  
				Strangely enough, M. Planté, the original inventor, applied for 
				a patent for the same process on the same day, and ultimately 
				two separate patents were granted to the rival claimants, by the 
				Solicitor-General. Elwell and Parker later purchased M. Planté's 
				interest in the process. |

				Thomas took out several patents for improvements to alternators, 
				and in 1881 was involved in the electric tramway at Portrush, in 
				Northern Ireland. This was the first electric tramway in the 
				world to be powered by hydro electricity.  
				Thomas was very interested in politics and became an 
				enthusiastic supporter of the Liberal cause. This was possibly 
				because of his upbringing in Coalbrookdale where the Darby 
				family were staunch Liberals. Thomas joined the Liberal Party 
				and became a member of the Executive Committee of the Borough of 
				Wenlock Liberal Association. |

				He used to lecture at the Coalbrookdale Institution, and on 
				Tuesday, 9th February, 1882, 
              gave the first successful demonstration of Swan and 
				Edison’s incandescent lamps3. 
				There were seven lamps, which were run from two Parker storage 
				batteries. The lamps ran for fifteen minutes and provided 20 
				candlepower, and lit the room nearly as well as the 18 gas jets 
				that were usually in action.  
				
				In June 1882, Paul Bedford Elwell and Thomas Parker jointly 
				registered a patent for "Improvements in dynamo electric 
				machines", 
				and in August they took out another patent for "Improvements in 
				electric lighting and apparatus associated herewith".  
				Thomas decided to join forces with Paul-Bedford Elwell, in 
				Wolverhampton, to form the first company in the Midlands to 
				manufacture electrical equipment. He left Coalbrookdale in 
				October 1882 and moved to Wolverhampton.
