EDWARD OSCAR KUENDIG, F CANTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ARTHUR S. KOENREICH, OF CANTON, OHIO AlR-TJOVING APPARATUS Application filed December 18, 1928.

The invention relates to improvements in air moving apparatus and more particularly7 to supports for an air displacement unit of a vacuum cleaner such as shown in the application of Walter S. Simpson, for vacuum cleaners, filed September 17, 1928, Serial No. 306,524, by means of which the unit may he utilized as a blower, for drying,` hair and other air impelling uses.

Almost every home is provided with one kind or another ot vacuum cleaner which is used for-a short time every day for cleaning` purposes. However, the air displacement unit of such cleaner is not adapted for use other than for cleaning purposes, except that they may sometimes be used as blowers in a manner illustrated by Patent No. 1,293,250 issued to Walter G. Trautman.

When such a construction is used as a blower, the blower nozzle has no permanent support and the blower nozzle may not he directed in any direction except through the medium of a person handling, holding, and directing the same. Such use is restricted and encumhered by the presence of the vacuum cleaner handle, nozzle and other parts unnecessary when the cleaner is being utilized as a blower.

For instance if it were desired to use suc-h a cleaner as a hairdryer in the home, it would he necessary to have some person other than the one whose hair is being dried, manipulate and direct the nozzle in proper directions in order that the blast may be used to eifectually dry the hair.

The objects of the present invention include the provision of a simple inexpensive support AFor the air displacement unit ot a vacuum cleaner, which may be included as an attachment for the vacuum cleaner` when the same is sold, and hy means of which the vacuum cleaner may he easily and readily converted ior use as a hair dryer. adapted for being conveniently located with reference to the person whose hair is being dried, and for heing manipulated and directed in any direction by that person without the aid of another.

These objects are attained by the present improvement, preferred arrangements of Serial No. 326,845.

which are hereinafter set forth in detail, and may inclu-de a support member for the air displacement unit of a vacuum cleaner, the support having a tubular post for connection with the inlet orifice extension of the air displacement unit, by means of which the unit i may be swivelled in or on the tubular post, and the tubular post being provided at one of its end portions with an opening or openings tor the admission of air to the air inlet orilice of the air displacement unit.

Valve means may also he provided for the opening or openings in the tubular post tor crritrollingl the quantity of air admitted to the air displacement unit inlet oriice.

Several embodiments of the invention are illustrated in the accompanying drawings, in which Figure l is an elevation of a vacuum cleaner. the air displacement unit of which may he easily and readily converted for use as a hair dryer or other air impelling apparatus;

Fig. l2, a plan sectional view as on the line 12-12, Fig. 1l.

Similar numerals of reference refer to corresponding,` parts throughout the various ligures of the drawings.

The air displacement unit generally indicated at 15, is provided with an angled nozzlc tube 1G, rigidly secured to the inlet orifice extension 17 b the clam infr screw 18 andl a nozzle 19=is swivelled at the lower endof the, nozzle tube 16.

The outlet orifice connection 20, of the air displacement unit 15, may beA provided with a dust collector bag` 21, r nd the unit may also be provided with a handle 22 for manipulating the cleaner. Conveniently located adjacent the handle 22, is the switch 28, for the motor 24, of the air displacement unit, and the wires 25 may lead to' any suitable source ot electric power supply.

The centrifugal impcller 'tan 2o may he mounted` in the fan casingr 27 and driven by the motor 24 as shown in Fig. 2 of; the drawings;`

lVhen it is desired to utilize the air displacement unit 15 of the vacuum cleaner' as a blower unit and more' particularly as a hair dryer, the nozzle tube 1:6" may be disconnected from the inlet oriiicei extension 17 by loosen ing the clamping' screw 18, and thedust collector bag4 21 may be disconnected from the outlet orifice connection 20.

The inlet.oriiceexten'sion 17 may then have nipple connect-ion 28 rigidly1 secured thereto', by the' clamping screw 18, and aportion of the nipple connection 28, may then be swivelled ini the tubular post 29, which may extend vertically of the support indicated at 80.

For admitting' air to the air inlet orifice of the air displacement unit 15. the' support 8() may be-proif'ided: with legs 31 for spacing the sa me from a table or other 'H at surface K upon which the support rests; and on openingr 32 may be providedifn the support aligned with the duct 33 of the post 29.

'llhe tubular post 29 ina-y be connected to the support by thescrews-oi" rivets 34, and for .simplifying the construction of the support. the tubular post 29 may be a casting similar to the inlet oriiice extension 17 of the air displacement unit 15: but the clamping screw 35 thereof. will not be used to clamp the nipple 28 il the clampingT screw 18 is used tor that purpose. for it is usually dcsired to provide a swivel connection between the support 30 and the air displacement unit l 5.

A nipple connection 86 may be connected with the outlet orifice 2O of the unit 15, and a nozzle 37 may be applied to one end thereof as shown in Fig. 2 of the drawinos. The nozzle 37 may be made of rubber and may be the attachment supplied with the vacuum cleaner for use when' cleaning upholstery.

The construction and arrangement shown in Fig. 2 maybe read-ily and satisfactorily used as a hair dryer in which the displaced air flowsbetween the support 30 and the table A, then upward through the opening 32, the tubular post 29, the nipple 28, and the inlet orifice extension 17, to the iinpeller fan chamber inside the casing 27, and thence is displaced through the outlet oritlce connection 20, the nipple 36, and is expelled through the nozzle 37, as shown by the arrows in-Fig. 2 oi the drawings.

By this construction, the nozzle 87 may be directed in any direction in the plane of its longitudinal axis by swivelling the unit 15 at the nipple connection between the same and the support 30, and this manipulating or directing of the nozzle may be readily aecomplished sim ply by grasping the conveniently located handle 22.

At times it may be desirable to limit the amount ot' air displaced by the fan 26, and: for this purpose a valve 3% vis provided,v pivoted at 4() onzthe .support 30. There-may also be provided on the valve-39, a depending tonguev 11 lo be `:grasped between the finge-rs for movingl the valve to any position..

'l`he valve 39 is shown in dot dash lines at 39 in Fig. il, in a. partially closed position for limiting the quantity ot air which may be drawnl through the opening 32 tothe fanl chamber inside the casing27.

Ac slightly modified form of support is shown in Figs. and 6", whichis the same as the construction shown'iny Figs. 2, 8 andfl exceptingr,- that thereis a sub-base 42 spaced from the support 30 as by the' pins 43', for permitting air to enter between the sub-base 42 and thesup'port 80. The air then travels Figs. 7 and 84 sho a: still further modifiedfornil ot swivel support for an air displace'- nient unit in. which the inlet orifice extension 17 o the unit may be connected bythe clamping sere-w 18, with the nipple 28, which may be inserted into` and swivelled' in the upper cylindric portionl 50, of the tubular post indiratedi generally at 51.

The lower portion of the tubular post 5]., niaqyy be flared as at 52. and may he connected by screws through its peripheral flange 54. to the support 55, provided with legs 56 tor contact with the table A or other fiat surface.

The flared portion 52, of the tubular posi. 5l, may be provided with a number of openw ings 57 for the admission ot air to the lower end of the tubular postJ as indicated by the arro in Figs. 7 and 8*. The air then travels upward throughy the nipple 28,. and air inlet orifice extension 17 to the fan chamber in the casing 27.

The construction shown in Figs. 7 and 8 does not contain an opening in the support for all of the air enters the interior ot the tubular poet through the openings 57.

Tn the construction shown in Figs. 9 and 10, the nipple 60, connected with the air inlet orifice extension 1T, by the clamping screw 18, may be provided at its lower portions with openings 6l, which may register with openings G2. in the lower portion of the tubular post (SI-3. attached to the support 64, as by screws 65, extending through the peripheral flange 66 thereof.

When the nipple is inserted in the tubular post 63, the openings 61 and 62 may register for the admission of air through the same, then the air travels upward through the nipple 60, and air inlet orice extension 17, to the interior of the fan casin 27.

When it is desired to limit t e quantity of air passing to the fan, the nipple 60 may be swivelled or rot-ated within the tubular post G3, thereby causing a misalignment of the openings 6l and 62. The support 64 is spaced from the table A or other fiat surface as bylegs 67.

A still further modified form of swivel support for the air displacement unit 15 is i shown in Figs. 11 and 12. which may include a tubular post 70, from which extends tripod legs 71, contacting with a table A or other fiat surface by knobs 72. The nipple 2S connected with the air inlet orifice extension 17. by the clamping screw 18, may be swivelled within the tubular post 70, and air is admitted at the lower end thereof as shown by the arrows in Fig. 11.

By any of the foregoing means, a simple and effective support is provided, in which the air displacement unit of a vacuum cleaner may be swivelled, and tl'irough which air may he admitted to the inlet orifice ofthe air .iisplaceinent unit. Thus the air displacenient. unit may be effectively utilized as a hair dryer, the nozzle of which may be turned in an;y direction in the plane of its longitudinal axis.
