AIR-BLAST.
SPECIFICATION forming part of Letters Patent No. 250,073, dated November 29, 1881.
Application filed Scptemberi, 1881. (No model.)
To all 'whom it may concern:
Be it known that I, SAMUEL W. HUDSON, of Hudsondale, in the county of Carbon and State of Pennsylvania, have invented certain new and useful Improvements in Air-Blasts, of which the following is a specilication.
The object of my invention is to provide ap paratus by which, with a given primary or initial blast, a blast of increased volume but decreased pressure or velocity may be produced as desired.
In the accompanying drawings, Figure l is a vertical longitudinal section, and Fig. 2 a transverse section on the line 2 2 of Fig. 1.
A is an ordinary blower-fan, its blast being delivered through the pipe a. The pipe t extends into the aring end of a pipe, B, of larger diameter, and the pipe B in the same manner projects into a larger pipe, C. Sliding collars or cut-offs D D on the pipes a and B serve to close or regulate the size of the annular open-y ings .r and y between the pipes a and B and the pipes B and C, as will be clear from `the drawings. The fan A, being driven at a given speed, will produce a blast through a, which will draw air through the annular opening x, thus increasing the volume and decreasing the velocity.. The blast, passing on through B, in like manner draws in air through the annular opening y. The collars can be adj usted to vary the size of the openings and regulate the volume of the blast delivered at Z. Thus, forexample, with a blast in a, with a volume otone hundred feet and a pressure of six pounds per square inch, I may produce at Z a blast having a volume ot' six hundred l'eet and a pressure of one pound.
It will be seen that the fan may be run at a uniform speed and the character of the blast varied by adjusting the collars on the pipe. The primary blast may be generated in any suitable manner.
My invention may be used in connection with exhaust or pressure ventilatingapparatus, or for any other purpose where such an operation as that above described is desirable.
` What I claim isl. The combination of the blower-fan, the blastpi pe a, and the pipes B and C, projecting one within the other and having aring ends, substantially as described.
2. The combination ot' the blower-fan, the pipes a, B, and (l, and the sliding regulatingcollars D, substantially as set forth.
3. The combination of the blast-pipe, the air-supply pipe into which the blast-pipe projects, and a device for controlling and regulating the air-supply, as set forth.
In testimonyT whereof I have hereunto subscribed my name.
SAMUEL W. HUDSON.
