Claims. (Cl. 34-90) Generally speaking,'the present invention relates to the clothes-dryer art and, more particularly, pertains to a clothes-dryer adapted to be inserted into a home oven, and energized by an electric source, to allow the effective heating, tumbling and ventilation of fabrics placed therein to remove moisture therefrom.

;I am aware that many home clothes-dryers have been invented and developed heretofore; but all such prior devices, known to me, have suffered from numerous disadvantages. ,They are provided with their own cabinets, heat sources, electric and often gas connections, and in their mechanical workings are quite complex: thus they are exceedingly expensive, and are not economic for most homes. Further, their cabinets occupy a great deal of space, much of whichis waste space-and space is of value in a small house or apartment. However, a compact, inexpensive clothes dryer would be of great value in most homes; it is to answer this need that the present invention has been developed.

Genetically speaking, the present invention comprises support-case means slidably insertible into the oven of a household range or the like, having front wall means by which the entrance-aperture at the front of the oven can be effectively elosedagainst the uncontrolled flow of air therethrough (i. e., the flow of air around said wall means is blocked); tumbler-drum means consisting of multiple apertured cylindrical shell means having rear fully closed end means andhaving front partially closed end means (spaced from said rear end means) with fabric-inlet aperture therein, said tumbler-drum means being rotatably held by said support-case means to have said fabric-inlet aperture adjacent said front wall means, and to be rotatable about a longitudinal axis of said shell means, usually virtually perpendicular to said front wall means; said front wall means being provided with selectively closa'ble door means cooperable, when open, with said fabric-inlet aperture to allow fabrics to be placed within said tumblerdrum means; rotary fan means, cooperable with said tumbler-drum means to bein rotatably driven relation-.

ship thereto, and a fan-aperture defined by said front wall means, said fan being mounted in said fan-aperture to selectively force air into said oven (when in use); an

air-exit aperture defined by said front wall means; and

motor means, energizably connectible to an electric source, in rotatably driving relationship to said tumbler-- drum means.

In one generic form of the present invention, at said fully closed end means the tumbler-drum-means is connected by a (co-axial thereto) shaft and bearing to rear" 2,775,824 Patented Jan. 1, 1957 thereto) may be mounted at the back of the oven itself in a (more or less) permanent fashion.

In some formsof the present invention, the tumblerdrum means may beprovided with a plurality of longitudinal fins, mounted within (on the inner surface of) said cylindrical shell angularly spaced from each other, to increase the fabric-tumbling action of the tumblerdrum means.

To use the clothes-dryer of the present invention, one first places it in an oven; opens said door means and places fabric materials (damp clothes, e. g., previously damp-dried by a wringer or centrifuge) within the tumbler-drum means; closes said door means, turns on the oven heat, and energizes said motor means to actuate the tumbler-drum and fan means. The fabric materials are then tumbled, heated by air passing through the tumblerdrum apertures, and ventilated until dry (the oven temperature soon stabilizes at a warm level).

From the above description of the basic form and various preferred formsrof the present invention, it will be apparent to those skilled in the art that the hereinabovementioned disadvantages of prior clothes dryers are virtually entirely eliminated and overcome in and through the use of the present invention.

For example, the present invention makes use of a cabinet and heat source-namely a range ovenwhich are ordinarily found in a home, and is of mechanically simple but effective construction; thus the present invention. can be manufactured at low cost. Further, it is extremely compact: it can ordinarily be stored, in place, in the oven, but will occupy little space when removed from the oven to permit the ovens use in cooking.

With the above points in mind, it is an object of the present invention to provide an electrically operated clothes-dryer adapted to be inserted into an oven and cooperable with said oven to heat, tumble, and ventilate fabric materials placed therein to remove moisture therefrom. r t

It is also an object of the present invention to provide inexpensive and compact apparatus cooperable with the oven of a home. range to form an effective clothes-dryer and readily removable from said oven.

Other and. allied objects ofthe present invention will occur to those skilled in the art after a careful study of the present specification, the accompanying illustrations, and the appended claims.

To facilitate understanding, reference will be made to the hereinbelow-described drawings, in which:

Fig. 1 is a perspective view of a preferred embodiment of the present invention as it appears (from the front) when placed in an oven' ready for use;

Fig.2 is a perspective view of the device of Fig. 1 as it appears (from a rear vantage point) when removed from the oven (a portion of said side wall means being broken away for clarity);

Fig. 3 is a sectional view of the device of Fig. 1, the plane and direction, of the section being indicated by the line and arrows IIIIII of Fig. 2;

Fig. 4 is a sectional view of the device of Fig. 1, the plane and direction of the section being indicated by the line and arrows IV--IV of Fig. 2;

Fig. 5 is an enlarged detail of the sectional view of Fig. 3;

Fig. 6 is a view, similar to Fig. 5 in location, of a portion of a modified form of the device of Fig. 1;

Fig. 7 is a perspective view of a second preferred embodiment of the present invention, installed in an oven, various parts invisible from this vantage being indicated by dashed lines; and

Fig. 8 is a sectional view of a portion of the device of Fig. 7, the position and direction of the section being indicated by the line and arrows VIIIViIl of Fig. 7.

The parts of the modified form of Fig. 6 similar to those of the device of Fig. 1 will be numbered similarly, but with primed reference numerals; the parts of the embodiment illustrated in Figs. 7 and 8 similar to the parts of the device of Fig. 1 will be numbered similarly, but with doubly primed numerals.

Generally speaking, the present invention includes support-case means made up of front end-wall means, side wall means, rear wall means, and apertured bottom means; in the specific form illustrated in Figs. 1-5, the supportcase is formed by front end-wall 1, sidewalls 2a and 2b, rear wall 3, and bottom 4 carrying insulation (e. g., asbestos) at Sand defining apertures 6 to permit heat from the oven-bottom to pass therethrough. Also, generally speaking, the present invention includes multiply apertured tumbler-drum means rotatably mounted on said support-case means; in the illustrated form, the tumblerdrum consists of metal cylindrical shell 7, having a plurality of apertures 8 therein, having a closed end-closed by metal disc 9, and having a front end partially closed by the generally annular member 10, which defines a central aperture A. Attached to disc 9 is shaft 11, supported by the thrust-type ball-bearing 12 held by rear wall 3. Within the shell 7, four longitudinal fins 13 are attached to the shell, angularly spaced from each other, to aid in tumbling fabrics placed in the shell when it is rotated in use.

Generally speaking, the front end-wall means is provided with door means; in the illustrated form, opposite tumbler-drum aperture A is an aperture, in front endwall 1, which is shown closed by a door 14 hinged by pin 15 to a projection 16 of the front end-wall 1 and having a handle 17 by which it may be pulled open to permit fabrics to be introduced or removed through aperture A. Said front end-wall means, generally speaking, defines a fan-aperture, in which rotary fan means is mounted to be in rotatably driven relationship to the tumbler-drum means; in the illustrated form, aperture B in end-wall 1 holds rotary fan 18, which has a fan pulley 19 driven by a belt 20 which passes around the track 21, mounted circumferentially on cylindrical shell 7 at the front end.

Also, generally speaking, the tumbler-drum means is rotatably mounted at its front end, having track means supported by roller means rotatably mounted on endwall 1. In the form of the track and roller means explicitly shown in Figs. 3, 4, and 5, the track means is constituted by the portion 7a of shell 7 between its front edge and a lip 19a of annular member 10. The four shafts -22 rotatably support rollers 23, which ride in track 7a, rotatably supporting the tumbler-drum. In the modified form explicitly shown in Fig. 6, a circumferential ring 24 is attached, e. g. by bolts as shown at 25, to annular member 10 and shell 7; belt 20 rides in a track-portion 24a of the ring; shafts 22 hold grooved rollers 26, which ride on the track formed by inner rim 24b of ring 24. The rollers shown'in the two forms of Figs. 5 and 6 ride hypocyclicly with respect to the shell; it would also be possible to use epicyclic rollers (riding on the outside of the shell) at some sacrifice of compactness.

Further, generally speaking, the present invention includes motor means in rotatable driving relationship to the tumbler-drum means. In the first embodiment illustrated, as seen explicitly in Figs. 14, a motor 27 is mounted on end-wall 1, and has a drive pulley 28 in driving relationship to belt 20, thus driving the tumblerdrum (and fan). To energize the motor, it may be connected to an electric source (not shown). In the embodiment of Figs. 7 and 8, motor 27 has a worm-shaft 29 which with gear 30 forms a reduction-drive for (squarecross-sectioned) male shaft 31, held in roller-bearing 12"; onto shaft 31, female shaft 11 from the tumbler-drum (which rests on saddle bearing 32) may be removably rotatably-drivably engaged. The motor 27" and bearing 12 are fixedly mounted on the back wall of an oven D", into which the remainder of the clothes-dryer apparatus may be inserted, shaft 11" being thus engaged with shaft 31 (which passes into the oven at aperture 35), when the device is to be used or stored between other uses of the oven; that is, the motor assembly is more or less built into the range, to give the advantages of a fixed motor installationproper heat, sound, and electric insulation are more easily used, and the electrical connections (not shown) may be made simple and convenient. With the single exception of the motor assembly, the form of Figs. 7 and 8 is similar to that of Figs. 1-5.

Also, generally speaking, the front end-wall means of the present invention defines an air-exit aperture; in the form illustrated (but explicitly only in Figs. 1, 2 and 4) the aperture C in end-wall 1 is provided with a lint-filter screen 33. In Fig. 1, the clothes-dryer is shown ready for use in an oven D, having a heat-control 34 (which may be set, if thermostatic, at a temperature-reading at or somewhat above the operating-temperature chosen for the clothes-dryer-this operating-temperature is determined by the air-fiow from the fan, which removes heat from the oven). The end-wall 1 blocks the entrance to the oven; when the clothes-dryer is in use, air is forced into the oven through aperture B by fan 18, exiting through aperture C, whose lint-filter screen 33 prevents lint and fuzz from fabrics in the tumbler-drum from escaping. The motor, in any of the forms of the clothes-dryer, should (through its speed-reduction by belt or wormgear) drive the tumbler-drum at an angular speed which will (with the aid of fins 13) give a tumbling action to fabrics held within-that is, the centrifugal acceleration on the fabrics should be in the neighborhood of one g or gravity.

Numerous modifications and variations of the present invention will occur to those skilled in the art after a careful-study hereof. All such, properly within the basic spirit and scope of the present invention are intended to be included and comprehended herein as fully as if specifically described, illustrated and claimed herein.

For example, the number and location of the fins inside the tumbler-drum may be varied, or the fins maybe eliminated. The rotary fan could be used in the air-exit aperture (C) as an exhaust fan, instead of as an intake fan in the inlet aperture (B). Although the clothesdryer has been described as usable with the oven of a home range, it may, of course, be used in any similar heatable compartment.

The exact compositions, configurations, constructions, relative positionings, and cooperative relationships of the various component parts of the present inventionare not critical, and can be modified substantially within'the spirit of the present invention.

The embodiments of the present invention specifically described and illustrated herein are exemplary only, and are not intended to limit the scope of the present invention, which is to be interpreted in the light of the prior art and the appended claims only, with due consideration for the doctrine of equivalents.
