AIR PURIFIER AND BLOWER.

SPECIFICATION forming part of Letters Patent No. 731,927, dated June 23, 1903. Application filed December 6, 1902. Serial No. 134,073. (No modeL To all whom it may concern:

Be it known that I, FRED MARX, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented and produced a new and original Improvement in Air Purifiers and Blowers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to figures of reference marked thereon, which form a part of .this specification.

The objects of this invention are to provide a blower which shall furnish a supply of clean pure air; to provide means for separately removing from the air passing through said blower the coarser and finer particles of foreign matter or dirt; to secure a convenient construction and one in which all the are inclosed or boxed, both for protection and for ease of transportation, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved blower and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in

which like figures of reference indicate corresponding parts in each of the several figures, Figure 1 is aperspective view of the improved device With the front of the cabinet removed, a certain inside partition slid to one side, and certain sieves or screens, the fancasing and connecting-tubes being all re? moved. Fig. 2 is a perspective view of the fan casing. Fig. 3 illustrates one of the sieves or screens. Fig. 4 is afront elevation of the improved device fully set up, a portion of the front wall being broken away to disclose the interior parts; and Fig. 5 is a vertical section upon line m, Fig. 4.

In said drawings, 2 indicates a portable rectangular box or cabinet, which may be of any suitable size and is preferably formed of a double thickness of boards or sheathing. Into the upper part of the interior of the said cabinet extends a shaft 3, which at one side porting the projecting parts of the cabinet projects exteriorly to receive a driving-pulley 4, a bracket 5 suitably supportion of said shaft.

Within the cabineta fan 6, of auysuitable and well-known construction, is fixed upon said shaft to be rotated thereby. Said fan is disposed adjacent to the inner side wall of the cabinet and is adapted to be inclosed at its opposite side and periphery by a cylindrical casing 7, removably supported upon said side wall and with a tangential delivery-tube 8, as is common. Said delivery-tube 8 leads vertically downward into a narrow tank 9, stationed in the lower part of the box 2 in substantially the same plane as the fan 6 and into which the air is adapted to be driven.

The tank 9 has projecting up from its bottom a middle transverse partition 10, and on opposite sides of said transverse partition 10 are other parallel partitions 11 11, depending from the top of the tank to a lower level than the top of said middle partition 10. Said tank is adapted to be partially filled with Water, into which excelsior may be put to prevent undue splashing of the water. The said water or excelsior,or both,extend upward to or nearly to the said depending partitions 11 11, so that a current of air from the fan must necessarily pass through said water or watersoaked excelsior in its tortuous course through the tank 9. At the opposite end of the tank from that at which the pipe 8 enters from the fan is a vertical delivery-tube12, which extends upward adjacent to the periphery of said fan and through the top of the box or cabinet, as at 13. From this tube the supply of air is taken from the blower wherever it is desired to be used. Adjacent to the said fan 6 and tank 9, arranged one above the other at one side of the cabinet, as described, is a partition 14, which divides thecabinet vertically into compartments. other than that in which the blower and tank are stationed is provided at its lower part with a series of horizontal screens or sieves 15, which may be of varying degrees of fineness, adapted to successively strain out ofthe entering current of airdifferent kinds of dirt or foreign matter carried thereby. Said screens are preferably slid into ways 16 16 from the front of the box, and thus can be used or removed according to the kind of The compartment 7 work being performed. Below said screens 15 an air-inlet tube 17 extends through the side of the box or cabinet 2, and above said screens an aperture 18 in the vertical partition 14 between the two compartments admits air to the center of the fan 6, as is common.

The partition 14 is preferably removable, as shown in the drawings, so as to permit of greater convenience in assembling and disassembling the various parts and is normally held in place against the tank 9 and fan-casing 7 by the screens 15, which thus serve as braces.

In use it will be seen that all the working parts of my improved blower are boxed in, and at the same time if it is necessary to have access to said parts for purposes of repair or the like they can be readily reached by removing the front wall or side of the box 2. Furthermore, the air taken inis first relieved of its larger and coarser particles of foreign matter by the screens 15, so that it arrives'at the fan Gin fairly clean condition. This prevents leaves and other dirt being carried into and through the fan and not only enables an easy removal or clearing away of such dirt when it accumulates, but also keeps the fan in better condition. After leaving the fan the air is cleansed of all fine dirt and dust by passing through the water-bath 9 and so is delivered in a pure clean condition.

Having thus described the invention, what I claim as new is 1. In a blower, the combination of a .portable rectangular box or cabinet havinga removable front side forming a door or means of access, a removable tank or bath arranged at one side of the lower part of said cabinet, at fan-casing above said tank or bath and a fan therein, a duct leading from said fan-casing to the tank or bath, and a secondduct leading from the tank or bath out through the walls of the box or cabinet, a movable partition arranged vertically from front to rear of the box or cabinet against said tank or bath and the fan-casing, and screens extending horizontally between the side of said partition away from the tank or bath and the opposite side wall of the box or cabinet and bracing the partition in place, said facing walls having slideways receiving the edges of said screens, the partition and the fan-casing having coinciding apertures for the passage of air, and the box or cabinet. having an airinlet beneath said screens at the opposite side of said partition from the tank or bath.

2. In a blower, the'combination of a portable box or inclosing cabinet adapted to open at its front, a removable water-bath at one side of the lower part of the interior of said cabinet, a fan-casing vertically above said bath and a fan therein, ducts leading from said fan-casin g to the bath and from the bath to the outside-of the box, respectively, a removable partition disposed vertically from front 'to rear in the cabinet, adjacent to the said bath and fan, horizontal screens at the opposite side of said partition from the waterbath and fan, slidably supported at their edges between said partition and parallel wall of the cabinet, and means of communication between the fan-casing and the interior of the chamber on the opposite side of the partition from the fan and above the screens, the walls of the cabinet being apertured on the same side of said partition below said screens.

3. In a blower, the combination of a portable rectangular box or cabinet havinga removable front wall, a removable bath arranged in the lower portion of the cabinet adjacent to one side wall thereof, a drivingshaft extending perpendicularly through said side wall of, the cabinet at a higher point, a driving-pulley upon the outer end of said shaft and a fan upon the inner end, a fancasing detachably mounted upon said side wall, inclosing said fan, and communicating with. the water-bath, a duct leading from said bath to the outside of the box or chamber, a vertical partition extending from front to rear in said cabinet adjacent to the waterbath and fan, dividing ofi? a second compartment, and horizontal screens removably arranged in said second compartment, said compartment having in its walls an aperture above said screens into the fan-casing, and a second aperture below said screens into the open air outside said box.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of December,l902.

FRED MARX.
