GEO. E. NEW COMB. JAS. W. NE WOOMB. JOHN H. NEWCOMB §§ . They can be used either in single or double action, for light or heavy work as required. They maintain a steady and continuous blast, the air being forced into the chest both at the up and down stroke. The strength of blast obtained is double that of the ordinary bellows of the same dimensions. They work easily. While the blast is double, the power required to work them is no more than that of a common bellows. Being fully rigged and geared, ready for work, and easily moved from place to place, they are very convenient for railroad, mining, and other purposes where portable bellows are required. ... They economize space, occupying only half the room of an ordinary bellows. . These bellows come to hand at once. A good blast is obtained at the first stroke, and no time or labor is lost, as in the old single-action bellows, in getting up a good blast. They can be made of any size and shape, to suit all requirements. They are the cheapest bellows in the world. With all the advantages of double-action, they cost no more, power for power, than the common single action of same quality. to For further particulars send for descriptive circular and price list. 586 WATER ST., near Montgomery, NEW YORK.
