AppUcatian of the Bhzv-pipe. 241 



tach eight inches, and whofe leaft diameter was fix inches 

 and a half. It was more eafily faftened to its appendages 

 when of this conical form than if it had been cylindrical. 

 At the protuberances Ff , it is dillended by two iron rings, 

 to which it is fewed fad. 



FG, fig. I, is an iron rod, by means of which the top of 

 the bellows may be raifed or depreflfed. It pafTes up through 

 the pipe D to the handle G, which is worlced by the hand or 

 with the foot by means of the pendent ftirrup. An enlarged 

 view of this rod, and of the contrivance by which it is an- 

 nexed to the top, may be feen at fig, 3 ; where GD repre- 

 fents the rod, and H, H, H, H, flat pieces of iron branching 

 from it. Thefe are fixed to the circular rim KK in fuch a 

 manner as to include the rim 1 1, of the fame metal, which 

 is fcrewed fall to the top of the bellows. Sufficient room is 

 left to allow the j)ieces H, H,H, H, and the rim KK, to 

 move round without rubbing againft the included rim 1 1, 

 or the top of the bellows. 



A copper hood, with an opening in one fide, may be ob- 

 ferved at L, fig. 3. The rod GD is pafled through the centre 

 of this hood, until the flat pieces of iron H, H, H, H, come 

 in contaft with the flat part of it. The hole in the centre is 

 then luted. The hood may be feen in its proper fituation, 

 at F, fig. I. 



HI, fig. J, is a fuftion-pipe half an inch in diameter. 

 It pafles under the cafk in the direftion of the dotted lines 

 at C, and turns up into the hole in the bottom of the bel- 

 lows. This hole, which is of fuch a fize as to fit the taper- 

 ing end of the pipe, is fccn at fig. 3, and has already been 

 mentioned, together with a circular rim of wood, which, 

 being nailed ropnd it, prevents the end of the pipe from 

 touching the vah'c. The fuAion-pipe has a conical mouth 

 at I, into which is inferted occafinnally the pipe J, faftened 

 to the hofe and fvphon K, L. The hofe is made of leather, 

 diftended by hollow cylinders of tin half an inch in diameter 

 and one inch in length. Thefe were coated with tar, after 

 which the leather was fcwed over them *. 



Fig. I, MNO, ni n o, are pipes of delivery, furniftied with 

 cocks at N,n, and conical mouths at 0,o. Each of thefe 

 pipes communicates with one of the compartments on each 

 fide of the flieet and pipe EE, D. 



In the partition B, may be obferved the pipe Y, furn'iflied
