IMPROVEMENT IN REVERSIBLE SCREW-FANS.
Specification forming part of Letters'Patent No. 133,772, dated December 10, 1872.
. buckets confined between a closed drum on a rotating shaft and a surrounding cylinder or easing, the construction and arrangement being as hereinafter` more fully described.
In the accompanying drawing, Figure l represents an end view, showing the general construction and arrangement of parts; and
" Fig. 2 is a vertical longitudinal section of Fig.
Vl taken on the line x x.
Similar letters of reference indicate corresponding parts.
A is a rectangular-shaped frame of suitable dimension, made of Wood or other vsuitable material. B is the fanshaft, supported in boxes C C upon the frame, as represented in Fig. 1. B is the drivin g-pulley. D is a closed drum on the shaft B. E represents the spiral buckets. These buckets or blades are attached to the drum D, and extending its length at an inclination of forty-live degrees (more or less) over its surface. A cross-section of any ends ofthe buckets or blades are attached to these arms.
It Will be seen that the sidesV of the drum Y and cylinder are parallel, and the buckets or blades conform thereto. The drum is closed, but the cylinder is open at both ends so that air can be forced in either direction.
This fan lmay be made of any lengthl and diameter, and of any suitable material. It is calculated to exhaust the air from a mine or to force air in by simply reversing the motion; therefore, for Ventilating purposes it cannot be surpassed.
For creating a blast of air for smelting-furnaces or other purposes it is designed to take the place of thecommon blowers.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The reversible screw-fan, consisting of the ,close drum D on shaft B, the spiral blades E,
and revolving case G, all constructed, ar-V ranged, and combined substantially as shown and described.
