IMPROVEMENT IN MESr^RS. WHITELAW AND STIRRAT'S 

 WATER-WHEEL. 



'J/////i/l/l/llilll!llllllimiTMinn.n , , . 



In the " Mechanics' Magazine " we have a suggestion for an im- 

 provement in Messrs. Whitelaw and Stiriatt's Water Wheel, given in 

 hist month's Journal, of which the accompanying drawing shows the plan, 

 which, with the assistance of Mr. George Whitelaw, Mr. James White- 

 law has invented for keeping the new patent water-mill out of tail- 

 water, nn is the main-pipe, b b are the arms of the machine, and c 

 is the top of its shaft. The arms work inside of an air-vessel //, 

 wliich is fixed down to a building, and is covered on the top, but has 

 no bottom. The shaft passes freely through a hollow cylinder fixed 

 above an opening in the top of//; and there is anotlier hollow cylinder 

 a, fixed also on the top of //, and so large in diameter inside as to 

 leave room for a third cylindrical jjart e, which is fixed upon the up- 

 right shaft to revolve easily in the space left between the other two 

 cylinders. The top of//, forms a bottom to the space which is be- 

 tween the two cylindrical parts first named, and e is fixed (upon the 

 shaft in such a manner that the joining will be air-tight. An inspection 

 of the drawing will make the arrangement, &c., of the cylindrical parts 

 intelligible, g is one side of the tail-race ; s is the opening through 

 which the water escapes from//) into the tail-race. 

 . Suppose now the space into w hich the cylinder e works sufficiently 

 •filled with water to form an hydraulic joint of the kind very commonly 

 used in gas works; then, if the machine is set in motion, the air, 

 which will in some instances be disengaged from the water, will re- 

 main in the vessel//, and press down the surface of the water in it to 

 the level n ji, or even lower. In this way, the arms of the machine, 

 although on a level below that of the surface m in, of the water in the 

 tail-race, will work clear of the tail-water. 



It may be found necessary to use a small pump to force air into //, 

 in order to lower the surface of the water. By running a quantity of 

 water from the main pipe into the air-vessel through an arrangement 

 of pipes similar to the water-blowing machine, air will be carried into 

 //. The space within which the cyhnder e works may be supplied 

 with water by a small pipe leading from a a. 



A water-mill composed of two round plates, the one forming the 

 top, the other the bottom of the passages for the water, with plates 

 on edge and properly bent, running between them from tlie centre 

 outwards, so as to make the space between the round plates all into 

 arras, will work very well in tail-water. If a ring, projecting down- 

 wards is fixed to the under plates, then the bottom of the machine will 

 rub on a film of air, instead of on water, and thus the friction will be 

 diminished. This plan may be used instead of the one herein de- 

 scribed, in certain casos. 



IMPROVED JACQUARD APPARATUS. 

 A machine has recently been added to the mechanical department of the 

 Salford Mechanics' Institution which promises for it a great increase of at- 

 traction. It is an invention of a gentleman of this town, and is called a 

 Jacquard apparatus. When appended to looms moved by power (as in the 

 present instance), or otherwise, it is capable of producing, either on light or 

 heav7 fabrics, not only a greater variety, hut also a wider and more extensive 

 range of pattern than any other kind of loom ; it makes a top and bottom 

 shed of any required depth, without the aid of weights and springs being 

 attached to the healds. The design is formed, and may be varied at any 

 moment by the apphcation of paper cards, or wooden logs and pegs. It wAl 

 weave with any number of shafts, from 2 to 30; and any length of pattern, 

 up to 5,000 picks may be produced by it. The invention is a vcr\- important 

 one to manufacturers. Other articles have Ukewise been added to the col- 

 lection within the last few days, but our Umits at present prevent us from 

 adverting to them. — Manchester Guardian. 



BIOGRAPHICAL NOTICE OF THE LATE MR. WILLIAM 



HAZLEDINE, IRON FOUNDER AND CONTRACTOR 



FOR PUBLIC WORKS. 



(From the Shreicsbiinj Chronicle.) 



With deep and sincere son-ow we record the death of our respected 

 and endeared townsman, the eminent iron founder, William Hazledine, 

 on Sunday, (October 2l>, at his house in Dogpole, in the "Tth year of 

 his age. 



It would be almost criminal to permit sucli a man to drop into the 

 grave like an ordinary human being, and tlierefore we hastilv present 

 a few incidents in his busy and honourable career through life. 



William Hazledine was born at Shawbury, and his parents removed, 

 while he was very young, to a house at Sowbatch, near a Forge at 

 Moreton Corbet, now Moreton Mill, about seven miles from this town. 

 His father was certainly not wealthy ; but his ancestors were highly 

 respectable, their remains occupying tombs in the church-vards of 

 Shawburv and Moreton Corbet ; and these tombs the dece;ised, with 

 filial regard, caused to be repaired a few' years ago; lie also presented 

 two handsomely carved oak chairs for the altars of both those churches. 

 During sixteen or seventeen of his early years he worked around 

 the vicinity as an operative millwright. His uncle, under whom he 

 was chiefly brought up, was a man of considerable abilitv as a mill- 

 wright and engineer; and, discerning the steadiness and talent of his 

 nephew, he recommended young Hazledine, only IG or 17 years old, 

 to superintend the erection of machinery at Upton Forge, the property 

 of the Sundorue Family: this was executed most satisfactorily. He 

 afterwards became the tenant of this forge, and the farm belonging 

 to it, and so continued in after life. 



After the patronage of his uncle he removed to Shrewsbury, and 

 entered into partnership with Mr. Webster, in Mardol, then a clock- 

 maker, but afterwards an ironmonger and the patentee of a washing- 

 machine. Their first foundry was in Cole-hall, or Knucking- street, 

 in this town; but the speculative and energetic mind of Hazledine 

 having increased the business, more space for workshops, and an in- 

 creased expenditure for that purpose, amounting to about 2,000/., 

 were necessary : his partner being cautious and timid, a dissolution of 

 ()artnership took place. 



Mr. Hazledine purchased the ground in Coleham, where his present 

 foundry is situated, which has now four gables fronting the road. He 

 prudently first erected one worksho]), which occupied oulv one of 

 these gables ; but as business increased he extended liis shops, and 

 numerous other erections in the vicinity. He subsecpiently occupied 

 a foundry near Ruabon, iron works at Calcott, lime works at Llanymy- 

 nech, timber yards, brick yards, and coal wharfs, in various places. 



About this time Billingsley iron mines, near Bridgnorth, were offered 

 for sale in Chancery. Hazledine attended the sale in London, and 

 found there was some jockeyship employed to depreciate the property, 

 and prevent the sale, certain parties being anxious to purchase the 

 works without any competition. Hazledine's sagacity saw the trick ; 

 he bid with spirit: at length one of the parties, who wanted to pur- 

 chase, came to him, and whispered — 



" Do you know what you are doing? These mines and works have 

 not a good title, and you will liave to pay the expenses in Chancery if 

 you purchase them." 



In an audible voice Hazledine answered — 



" A bad title to the property, is it, eh '. and a Chancery suit, too, eh ? 

 Well, I have bought many things, and I will now try to buy a Chancery 

 suit. 



He did purchase the property, but immediately sold it, gaining seve- 

 ral thousand pounds. The property finally turned out ruinous to the 

 speculators. 



In November 1S04, at midnight, a fire took place in a room which 

 was the receptacle for his patterns for castings. Mr. Hazledine was 

 from home, but his wife (a daughter of Mr. Brayne, of Temhill), an 

 uncommonly strong-minded woman, heard the cry of "Fire in Hazle- 

 dine's foundry," whilst in bed with her infants, and immediately getting 

 up, gave directions for saving the books, papers, and other valuables, 

 which caused their rescue from the Haines, wdiilst a vast quantity of 

 other property w;is consumed with the building. Mr. Hazledine .vas 

 then the captain in a company of volunteers ; and his company, 

 comprising chiefly his own workmen, was merrily called " The Vul- 

 cans." The colonel. Sir Charles Oakely, Bart., and the whole corps, 

 were roused, and much property was saved. It was estimated that 

 the loss was 1,500/., and that about two-thirds were covered by in- 

 surance. 



Undaunted by the calamity, he rebuilt and extended his foundry, 

 and carried on his various speculations, above enumerated, with great 

 energy. Thomas Telford, who in after life became the celebrated en-
