J.- LONGWORTH. HIGH PRESSURE BLOWER.

HIGH-PRESSURE BLOWER.
SPECIFICATION forming part of Letters Patent No. 435,506, dated September 2, 1890.
Application filed November 2, 1888. Serial No. 289,841. (No model.)
To all whom, it may COR/0677b.
Be it known that I, J OS HUA LoNsWoRTH, a citizen of the United States, residing at Brooklyn, in the county Kings and State of New York, have lllveld certain new and useful Improvements in Iigh-Pressure Blowers; and I do declare the following to be a full, clear, and exact description of-the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to blowers; and it consists in an improved construction of the same, as hereinafter described and claimed,
the object being to construct a high-pressure receiver or tank, as indicated by the line ,2 .2
' chambers G, from'which the.- air is forced to the tank B. Aswill be seen,there are two adjoining chambers F and G on each side of the central shaft 0, and these chambers F and Gare separated by partitions I. The upper chamber E and the corresponding lower chamber are separated by the side chambers, the central shaft 0, and the packing a on each side of said shaft.
Openings Z) are made in the casing A to admit exterior air to the chambers F, each of which is provided with two valves 0, by which it communicates with each of the chambers E, as seen in Fig. 2. Each of the chambers G is connected by a pipe J with the tank B,
and also has communication with both of the chambers E by means of two valves (1, as seen in Fig. 3.
The shaft 0 is provided with a crank f, which is connected by a pitman with a shorter crank g on a shaft h, to which rotary motion may be imparted through a band-wheel on said shaft h. The rocking of shaft 0 is thus produced and effects the swinging motion of the blades D, each of which occupies about one-quarter of a circle in its movement.
Air being admitted through the openings 1) into the chambers F is drawn through the valves 0 into the chambers E by the operation of the piston formed of the fan-blades D. The same movement of the piston forces the air from the chambers E through the valves d into the chambers G and through the pipes J tothe tank B. By this construction a twofold force is obtained, a single stroke of the piston, as indicated in Figs. 2
and 3, drawing air from the opposite chambers F into the upper and lower chambers E, and at the same time forcing air from the lastmentioned chambers through the chambers G and pipes J into the tank, and there is a continuous flow of air under pressure through the pipes J into the tank. The valves 0 and d are provided with closing-springs, and springs are also provided for the packing a, so that tight joints are formed between the walls of the side chambers and the shaft C. Similar spring-packing a may be provided for the edges of the fan-blades.
I claim 1. The combination, with a casing, of an oscillatory shaft provided with fan-blades, two non-communicating chambers in which the said blades severally operate, two opposite inlet-chambers, two opposite outlet or discharge chambers, and valves connecting the chambers containing the fan-blades with each of the inlet-chambers and with each of the dischargechambers, substantially as and for the purposes described.
2. The combination, with the upper and lower chambers E, of a central shaft 0, provided with fan-blades D, each of which extends into a chamber E, as shown, two opposite inlet-chambers F, and two opposite dis In testimony whereof Iaflix mysignaturein charge-chambers G, the said inlet and dispresence of two witnesses. charge chambers being each provided with valves communicating with the intervening J OSIIUA LONG\VORTII. 5 chambers E, a tank B, and pipes J, which con- WVitnesses:
