Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . on one or both sides of the finish on one side of the articles than onthe other is effected by the greater pressure exertedduring the passage through the last pair of rollers,by means of compound strain exerted on* the firstpair is about 200 lbs., and on thelast pair 2,000 lbs. Upon thelever is the seat R. The weightof the person feeding the articlescauses or assists in pressing theclothed roller E against the iron-ing roller D, with a yielding forcethat is necessary in ironing thearticles. Hence, when the personstops feeding and gets off the plat-form, the pressure is removed andthe rollers are separated. The ironing rollers B D areconstructed of cast iron and made hollow, and are heated internally by a mixture of gas and air. The principle of the burner, , is that of the Bunsen burner slightly modified. Fig. 2749 is a section of the burner, which isplaced within the ironing roller and is stationary. At one end of the roller is situated a pipe, which. 280 LAUNDRY MACHINERY. conveys to the chimney the products of combustion. The burner itself consists of a cylindrical tube F, Fig. 274S, which contains the tube I. The gas and air admixture (gas one part, air ten parts) is brought to the tube / by rubber tubing having gauge-cocks to provide for regulating the amount of admixture. At G G are orifices in the tube 7, where ignition takes place. With the ordinary burner it is found that in tubes of a 2760. small diameter combustion of the gaseous compound is not entire, owing to a deficient supply of oxygen. The consequence is, that 2748.
