MACHINE FOR SWEEPING CHIMNIES. 25l! 



obferviDg that they had taken down all ihe foot, and left no- 

 thing for it to do *. Upon which a fuggellion waa made, that 

 there was another chimney which had a fire alternately during 

 the winter f ; and on examination it was agreed, that, by the 

 appearance of the foot about the bread of the flue, the chim- 

 ney was very foul, of vvljich, however, I had my doubts. 

 But it was thought expedient to try that chimney ; and the 

 firft charge we gave it brought no foot. We gave it another 

 charge, but no foot came ; and it was thought beft to fend up 

 a boy, with proper implements, to fweep the chimney ; but 

 no foot came down, except what may be faid to be brought 

 away by violence, and did not exceed a quart-potful, and 

 with it much mortar or pargetting. 



This brings me to fome obfervations I have made on the 

 condition of chimnies in general, as to the foot they may 

 contain. 



I tried this machine at Shored itch Workhoufe, where the Trials of t^^ 

 chimnies are very lofty, for which reafon I preferred them ; "J^^'^j^j^j^^^^ 

 but when I came to fee their circurattances I fufpeded how it 

 was, and we tried two of them where the fires had been very 

 economical, and may continue fo winter after winter, without 

 ever requiring to be fwept at all, for reafons I will give by , 

 and by. I then went to a neighbour of mine, and we fwept 

 two of his chimnies ; one had no foot, the other had a good 

 deal ; and we thought fit to get a boy to go up the laft chim- 

 ney, and he brought down about a hatful of foot; however, 

 my neighbour was fatisfied, and figned my certificate to the 

 Committee at the Adelphi. 



We then went to another neighbour's, and fwept his parlour 

 chimney, and diflodged a great quantity of foot. We wer« 

 tb have fwept his kitchen chimney, but it having a fmoke-jack, 

 we could not apply the machine for want of the additional 

 pipe in Fig. 2. 



* It appears the committee had no regard to the effe6hn>£ any of 

 the candidate's inventions, any further than a fair thruft up th» 

 chimney' 



'f With another in the fame room I fuppofe.
