350 APrAUATUS FOR CLEANING CHIMNET!?, 



between the two brushes FF, in drawing fig. 2, is about 

 four inches. The wooden tubes D, (which are about one 

 inch in diameter,) through which the rope passes, should 

 not be too long; the shortest next the brush should not 

 exceed fifteen inches. They should gradually increase in 

 length as they recede from the brush to the bottom, where 

 they should not exceed thirty inches. The brush, fig. 3, 

 is a good deal similar to a bottle brush, the handle about 

 four feet long, made of whalebone, wrapped with iron or 

 brass wire, the brush part made of bristles only. It will 

 be found to be very useful in cleaning short Hues, &c. in 

 kitchen chimneys. 



Fig. 4 is a kind of tent, within which the machine may 

 Contrivance for t)c worked. It will be found useful in rooms, where it is 

 floot from flyino- particularly desirable, to prevent the least particle of soot 

 into the room, from escaping. The -cross bars E are of oak, about one 

 inch and a half broad, and half an inch thick, turning 

 upon an iron pin at/. GG are two small iron rods, slip- 

 ping upon pegs at h, to each of which is suspended a linen 

 curtain, the one next the chimney, H, a short one, the 

 other, as shown by the dotted line I, a long one, reaching 

 to and resting five or six inches upon the floor, ee are 

 small pegs, which, when the bars E are closed, fit into 

 the notches gg, so as to stop the bars in the proper place, - 

 and prevent their being opened the wrong way. When the 

 bars E are opened, they stretch the tapes K, Avhich are 

 fastened to the tops of the bars /i, and are about three 

 feet six inches long, to which extent only they suffer the 

 bars to open. When thus extended, and placed in the 

 proper situation, a loose sheet, of the same kind of linen 

 as the curtains, is thrown over, and hangs down over; 

 the tapes, and upon the floor at each end, buttoning to 

 the curtains at the corners, so as to form a complete tent, 

 about five feet long, four feet wide, and five feet high, with- 

 in vphich both the man and the boy can stand with the ma- 

 chine to work it.
