Specification of Letters Patent.

Patented 2M, 1! with,

drying and aerating machine especially designed for use in connection with the processes of dry and other cleaning.

The invention has as its primary object to provide a machine adapted. through the medium of centrifugal action. to thoroughly expel all soils, dirt and other foreign matter,

and to dry and expel all of the cleansing fluid or commodities from the articles placed within the machine and, to at the same time thoroughly aerate the said articles so that the odor of the said fluids or commodities will be entirely removed therefrom.

The invention has as a further object to provide a machinc of this character so constructed that in the normal operation thereof, air currents within the machine will be automati rally set up to thus ctl'ectually aerate the articles placed Within the machine.

A. still further object of the invention is to provide a machine so constructed that the moving air currents within the machine in the normal operation, thereof will tend to induce an inflow of fresh air currents which latter air currents will be directed immediately toward or against the articles placed within the machine, so that all odors of any cleaning fiuids'and commodities clinging to the articles will be removed therefrom.

A further object of the invention is to provide an improved rotatably mounted basket adapted to receive the articles to be dried and of such character as to attain maximum. results upon the said articles, through the force of centrifugal action, when. rotated at any given speed.

The invention has as a further object in this connection to provide an in'iproved mounting for the basket so constructed and arranged that the basket may be easily rotated and that a ready access may also be had to the basket for the purpose of placing articles therein or removing the articles from the basket. And the invention has as a still further object to provide an improved device of this character which will be du liable in use, and which may be placed upon the market at moderate cost.

Other and incidental objects appear as the description proceeds and in the drawings wherein we have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts tl'iroughout. the several views,

Figure 1 is a perspective view of our improved device, Fig. :2 is a sectional vle\v more particularly showing the construction and mounting of the several elements of the device, Fig. 23 is a perspective view particularly showing the shaft supporting the spider. carried by the. basket employ-ed, and Fig. el is a fragrulentary sectional view particularly showing! the mounting of the basket.

In the preferred embodiment of our invention as illustrated in the drawings. we employ a base which includes a preferably rectangular platform 10 havin, sills 11 to which are secured cross-pieces or boards 1'2. Mounted upon the platform It) is a block 13 at one end of which is arranged a vertically disposed and transversely extending block 14.

Rising from the block 13 at its extremity opposite the block ll are spaced vertically disposed posts 15 and 16 respectively, the said posts being arranged s-zuhstantiall v' parallel and being secured to the block 1?). Connecting the posts 15 and 10 at the upper extremities thereof a plate 17 and bearing over the said plate and arranged within the lines of the post 15 is a brace strap 18. the said strap and plate being held in position by scren s 19 or other suitable fastening; dc vices. The strap 18 is, at its free end sultablyconnected to the block 13 as more particularly shown in Fig. l of the drawings and is thus adapted to rigidly support the said post. Extending between the post 16 and the block H is a cross-piece 20 disposed in substantial parallel relation. to the block 1 and having its extremities respectively secured, in any suitable manner, to the post 1(3 and to the said l. lock. Mounted upon the block 13 and supporting the cross-piece 20 intermediate its ends, is a post ll which is, as will be observed upon reference to Fig. 2 of the drawings, arranged in spaced substantially parallel relation to the block 14:.-

Arranged to seat flatly against opposite (Ill side edges of the cross-piece Q0 and extendinp; between the posts 16 and :21 respectively, are closure plates The plates are provided with laterally directed longitudinally extending flanges seating flatly against the adjacent upper face of the block 13 and are detachably meld in position by screws or other suitable fastening devices as clearly illustrated in Fig. l of the drawings. Mounted upon the base thusformed, is a driving mechanism for the basket em ployed. This mechanism includes a tooth wheel arranged between the 'posts 15 and it; and mounted upon a shaft 25 which is joiu'nalerl within suitable sleeves 26 carried by the posts 15 and 16 respectively. Connected to the outer terminal of the. shaft is a crank 27 which is provided with a handle Mimntedupon the posts 16 and 21 respectively and arranged substantially parallel to the block 13 is a drive shaft 25 which is journaled, adjacent its extremities in suitable sleeves 30 carried by the said posts. Keyed upon the shaft 29 at one extremity, is a pinion 31 while a beveled gear 372 is keyed to the opposite extremity of the shaft.

Mounted upon the cross-piece 20 to abut at one side with the post 16 is a preferal'ily cylindrical casing 33 which is open at its upper end and the bottom wall 3% of which is secured to the said cross-piece in any suitable manner. Formed on the bottom wall, adjacent one side of the casing is a discharge spout 353 while the said wall at a point centrally thereof is provided with a suitable miening which is surrounded by an upstanding annular collar 36 projecting laterally into the casing as more partimilarly shown in Fig. 2 of the drawings. The purpose of this collar will presently appear.

Arranged within the casing 33 is a preferably cylindrical basket designated as a whole by the numeral 37. ilhe basket- 37 is prefer ably provided with a solid bottom wall 38 and a foran'iinous circular wall 39, the wall being formed with circumferentially spaced series of vertically arranged openings as clearly shown in Fig. 2 of the drawings. Freferably these openings relatively small in diameter and are arranged in close spaced relation, this also being for a purpose which will presently appear. Formed on the wall 39 at the open end of the basket is a substantially frusto-conical rim e0 Seating against the outer face of the bottom M11128 of the basket is a shaft supporting spider 41, best shown in Fig. 3 of the (lira-Whigs. This spider 41 includes a preferably cylindrical body portion 42 arranged centrally of the wall 38 and from which extend qua'tlrantly spaced arms 43. The "arms 443 at the outer extremities thereof are providecl with laterally directed lugs 44 seating against the circular well an of (in basket to be secured thereto in any suitable manner. Formed on the body portion 2.52 and arranged axially of the basket is 'a' (yr-- lindrical socket or sleeve 45 which is pro- The collar a rrang'ed to react with an anti-friction hear" I ing seated within a suitable recess formed in the adjacent upper face of the crosspiece .20 as more particularly shown in Fig. :2 of the drawing.

The anti-friction bearing 50 is shown in detail in Fig. l of the .ll':i\\'ll7, i:5. and it will be observed that the said bearing includes an annular substantially cup shaped casing 51 within which are arrancje l boa: hear ing rings 52 and 53 resgnuziively. luierposed between the said rings ruse. antzi-frirtion devices 5- while the. casing is form d with an inwardly extending annular lla 55 arranged to maintain the several rleu'ieuia of the bearing in assembled relat on. it will now be. observed that the ring or. is substantially frustorvinical. in. contour and is adapted to freely receive the shaft 47 to coact with the thrust collar -18. Thus. the bearing 50 will freely support the entire load of the basket and the contents thereof. it being, observed that the said basket is mounted concentrically within the casing 33 with the shaft 47 projecting freely through the collar 36 and extending freely through the cross-piece 20. Preferably, the shaft 47 at its free end is detachably received within a suitable bearing sleeve 56 mounted within the block 13, so that the said shaft will be rigidly sup orted in. operative position.

Removaby keyed upon the shaft 47 is a beveled pinion 57 arranged to coact with the beveled gear 32 and as will now be readi ily understood. the basket 37 may thus be readily rotated by turning the crank 27. The ratio of'the. gearing between the tooth wheel 24 and the beveled pinion 57.n1ay, o course, be varied atwill, but is preferably so formed that the basket 37 will be rotated at a relatively high rate of speed, while the crank 27 will turn but slowly. Thus, with comparatively small effort on the partof the operator, maximum results may be atmined through the centrifugal action set up.

within the basket 37 and in this connection attention is directed to the fact that in makama Mia in the openings within the circular wall 39 of the basket relatively small and, arranging the openings in close spaced rolatiom it has been found in use, that in providing a relatively large number of such openings Within the said circular Wall, that a basket so 'lm'uiod will oilioieutly operato, when rotated at a relatively high rate of speed, to eil'ect a. thorough drying of any articles plaootl within the basket.

Closing the open end of the casing- 33 is a frusto conical lid or cover 58 which at pori ihory is' provided With. on. annular laterally directed flango 5Qaclapted to tionaily engage the Wall of the casing; to provide a tight joint between the easing and the lid. lllouuteri Within the lid aml opening through the apex thereof an aro ially arranged tubular air-spout or inlet- 60 inner terminal of Whiolu whom the lid is applied to the casing, La arrangqocl as will he observed upon reference to 2 of tho drawings, to extend rortioally within the casing and tEtXHllI'liilSfi-ZS laterally upon our. sideoi. and alrovo tho upon and of tho basket 37.
