FAN-WHEEL.
SPECIFICATION forming part of Letters Patent 1\l'o. 265,984, dated October 17, 1882.
Application filed February l0, 1882. (No model.)
To all whom 'it may concern A Be it known that I, WILLIAM SCHMO'LZ, a citizen of lthe United States, residing at San Francisco, in the county ot' San Francisco and State of California, have invented acertain new and useful Fan-Wheel, of which the following is a specification.
The object of my invention is to provide a means for exhausting and forcing atmospheric air, vapors, and gases from and. into mines, ventilating and cooling buildings, railway-cars, Snc. l accomplish this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of myimproved fanwheel. Fig. 2 represents in plan one of the bladesor fans. Fig. 3 shows a central longitudinal section through a fan or blade.
' Similar letters of reierence are used to designate like parts throughout the several views.
My invention consists of a wheel provided with fans, blades, or paddles, between which are interposed short sections or plates set at an angle to a radial line drawn from the center to the circumference of said wheel.
The rim A is 'composed of a dat-sheet of metal, bent into a cylindrical form, or of an equal diameter throughout its width.
'lhe blades B, which radiate from the hub l, are set at an angle to the plane of revolution, and are formed preferably of sheet metal, and provided with corrugations D, which eX- lend in a direction across the blade or fan at right angles to the length of the blade, as is plainly shown in Fig. 2, and upon reference being had to Fig. 3 it will be seen that the corrugations are formed upon both sides ot' the fan or blade.
The sheet-metal plates E, ot' which two or more circles or series are interposed between the blades or fans, are out in the form ot' a rhomboid, or lozenge-shaped, and are so set between said blades as to form an angle of about forty-tive degrees with a radial line from the center to the circumference of the wheel, and also at about the same angle with the axis ot' the wheel, as is shown in Fig. 1.
The object in corrugating the faces of the fans or blades is that as the wheel is revolved upon its axis (by means ofa connection made by belt or otherwise with any suitable powercommunicating mechanism) the atmospheric lair, gases, or vapors which the fau-wheel is employed in moving will be more closely held or confined on the corrugations, or, in other words, that the increased superficial area given to the blades by means of these corrugations will enable them to impinge upon and displace a larger volume of air than if the blades were constructed of plain surfaces, and consequently a much greater moving capacity for a given sized wheel, by reason of the friction ot' the blades upon the air, will be had.
The object in providing the lozenge-shaped plates E is to further increase the suction and forcing capacity of the fan-wheel, and at the same time act as stays or braces to the fans or blades.
When it is found necessary to ventilate lthe tunnel, shaft, or drift of a mine the mouth of the excavation should be provided with a short drum or pipe', within which the'fanwheel is to be placed, mounted in suitable bearings, and rapidly rotated or revolved, so as to eX- haust or wlthd raw the impure air or gases contained therein, while at the same time the vacuum caused is heilig supplied with fresh air.
In the adaptation ot' my invention to the ventilation of buildings it may be placed either Vinside or outside of them in any convenient location or at the" mouth of conduits iliade for the purpose, and may be rotated in one direction to supply and in the opposite direction to exhaust the air.
When this device is to be used as a blastfan, or for the purpose of creating a pressure of air at a given point, the wheel may be placed at the mouth of a drum constructed in a taperin g form, so as to concentrate the current of air at the point of exit from the drum or pipe.
Having thus described my invention, what I claim, and'desire to secure by Letters Patent, 1s Y 1. In a fan-wheel, the combination, with the rim A and hub C, of the radiating blades B, set at an angle to the plane of revolution and provided with transverse corrugations D, substantially as and tor the purpose described.
2. In a fan-wheel, the combination of the rim A, hub G, corrugated blades B, radiating from the hub and set at an angle to the plane ot' revolution, and the interposed lozengeshaped plates or braces E, all substantially as and for the purpose described.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 9th day of December, 1881.
