SUCTION OR BLOWDN'G APPARATUS.

Patented May 10, 1921.

Application fi led November 17, 1920. Serial No. 424,596.

To all whom it may concern:

Be it known that I, IRA H. SPENIJER, a

citizen of the United States, and a resident of West Hartford, in the county of Hartford and State of Connecticut, have in-. vented new and Improved Suction-or Blow ing Apparatus, of which the following is a specification.

My invention relates to the class of apparatus for creating air currents for blowing or suction purposes, and an object of my invention. among others, is to provide a device of this class that shall be simple and comparatively inexpensive to construct and the operation of which shall be particularly effective.

One form of apparatus embodying my invention and in the construction and use of which the objects herein set out as Well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a view partially in side elevation and partially in central vertical 1ongitudinal section through my improved apparatus.

Fig. 2 is a view in cross section on plane denoted by dotted line 2-2 of Fig.1.

Fig. 3 is a view of that end opposite the motor, with parts broken away to show construction.

My improved apparatus as illustrated and described herein is formed in three sections, a motor section 5, a fan section 6, and an intake or valve section 7, all of which sec tions are made from sheet metal and which sections are secured together in any suitable manner.

The motor section 5 comprises two sides 8 formed from sheet metal and having sloping upper edges 9, outturned flanges 10 at the back edges, and hand holes 11 through which access may be had to the interior for any desired purpose.

A bottom plate 12 extends across the structure between the side parts and is secured thereto in any suitable manner, as by electric welding, and a motor supporting plate 13 extends between the side parts and has down-turned flanges 14 providing a means for securing this support to the side parts, as by electric welding or in any other suitable way. A motor 15 rests upon said cylindrical shape with partially closed ends 18 and 19, one of which ends has a small central hole for the motor shaft and the other of which endshas a much larger hole 20 to receive the casing of the valve section 7. Both of said ends have flanges 21 extending toward each other when the ends are in place and the barrel 17 is encircled by these flanges, the ends of said barrel resting against the faces of said ends 18 and 19 and is suitably secured in place as by electric welding or otherwise. All exhaust opening 22 is formed through the side of the barrel and an. exhaust nipple23 is secured to the barrel surrounding said exhaust opening as a means for conducting exhaust from the barrel.

-A diaphragm 24 extends across the barrel, dividing it crosswise, this diaphragm having a flange 25 resting against the interior ofthe barrel as a means of support for the diaphragm and which diaphragm has an eye 26 for theflow of air to the fan and exhaust chamber 27 located between the diaphragm and that end of the barrel next to the motor section. An opening through this end of the motor section is suitably packed against flow of fluid, as by means of a packing 28 of fibrous material held in place as by means of apacking plate 29 secured as by means of bolts. A diverting plate 30 ismounted on .the shaft 16 to divert any slight flow of fluid through. the shaft hole and thereby prevent its access to'oil within the shaft bearing and consequent removal of such oil from the bearing. l

Fluid directing vanes 31, preferably 'of curved form, are secured in any suitable manner with their edges against the diaphragm 24, these vanes extending from the inner surface of the barrel to the edge of the eye 26, and a return chamber plate 32 is secured to the edges of said vanes to provide a returning chamber 33, this plate being smaller than the diameter of the barrel 17 to provide an annular opening 34 from the inlet chamber to the return chamber 33. A hole is formed in the center of the return chamber plate for the shaft 16, and'a packing is supplied at this hole as hereinbefore set out with respect to the hole through the end 18. I

Fans of any suitable construction are secured to said shaft Within the inlet chamber 35 and the exhaust chamber 27, as shown opening or eye 43.

herein these fans comprising each a base 36 with a hub 37 thereof secured to the shaft 16, a blade plate 38 secured to the base, blades 39 with their back edges secured to said plate and their front edges having a front plate This valve section is inserted through the opening 20 into the inlet chamber 35 to such extent as may be desired and depending upon conditions of construction and special use to which the apparatus may be put, in which position said section is secured in any suitable manner, this insertion of the tube when the flange of the'end thereof is on the outside being made before the plate 42 and the end 19 are finally secured in place. A lining 44 is secured to the inner surface of the valve section and the valve, in the form shown.

herein comprising two flaps 45, is mounted to control the inlet opening, said flaps being preferably spring pressed into their closed positions, the spring, however, being insufficient to prevent opening movement of the fluid into the inlet opening 46.

I claim k 1. A suction or blowing apparatus casing comprising a motor section with Sides arranged in spaced relation, a motor supporting plate extending between the side parts and secured thereto, and a fan section having an end with its flat face secured against the back edges of said sides.

2. A suction or blowing apparatus casing comprising a motor section with sides arranged in spaced relation, a motor supporting plate extending between the side parts and secured thereto at a distance from the bottom edges of the side parts, a bottom plate secured to the bottom edges of the side parts and extending across them, and a fan section having an end with its flat face secured against the back edges of said side.

3. suction or blowing apparatus casing comprising a motor section with sides arranged in spaced relation, a motor supportflaps under the force caused by the flow of and having turned flanges with their sides 'secured against the faces of the side parts at a distance from the bottom edges thereof, a bottom plate secured to .the bottom edges of the side parts and extending across them, and a fan section having an end with its flat face secured against the back edges of said sides.

4. A suction or blowing apparatus casing comprising a motor section, a fan section separately formed from the motor section and comprising a barrel with an end plate having its flat face secured against the motor section, a diaphragm secured to the inner surface of the barrel andextending there across, directing blades secured with their edges against said diaphragm, a plate secured against the opposite edges of ,said blades, and a closure for the end of the barrel.

5. A suction or blowing apparatus casing comprising a motor section, a separately formed fan section secured to the motor section, and supported thereby and including an end plate, and a valve section comprising a barrel inserted through said end plate and secured therein.

6. A suction or blowing apparatus casing comprising a motor section, a separately formed fan section supported by the motor sectionand including a barrel and end plates having flanges to receive said barrel, one of said end plates being secured withits flat plates having a central opening, and a valvesection comprising a barrel inserted through said opening and projecting into an inlet chamber within the fan section, said valve section comprising a barrel with an end plate Y having a flange to receive said barrel.
