CLOTHES DRYING APPARATUS Monte F. Huebsch and Pierce Manfred Pearson,

The invention relates to clothes drying-apparatus.
The general object of the invention is to provide a clothes drying machine of simple and compact construction and whose first cost is not high so that the cost of several of these machines compares favorably with that of the large multipocket machines used by laundrles anda more flexible equipment is obtained as well as a saving in operating cost over the usual large laundry drying equipment.
A further object of the invention is to provide a clothes drying apparatus in which the clothes are tumbled about in a revolving drum while subjected to drying currents of hot air, the air being introduced into the drum through the aid of a fan whose casing forms the supporting pedestal for the drum and its casing. 1 p
The invention further consists in the several features hereinafter set forth and more particularly dened by the claim at the conclusion hereoi.
In the drawings: Fig. 1 is a vertical sectional view taken on the broken line I-I of Fig. 2;
Fig. 2 is a vertical sectional view taken on the line 2.-2 of Fig. 1;
Fig. 3 is a front end elevation view;
Fig. 4 is a detail sectional view taken on the line 4 4 of Fig. 3;
Fig. 5 is a detail sectional view taken on the line 5--5 of Fig. 1.
Referring to the drawings, the numeral 6 designates generally the pedestal, 1 the drum casing and 8 the drum.
The pedestal 6 includes a foot portion 9 and a fan housing Ill which includes thevinlet conduit II and the outlet I2, a fan or impeller i3 being mounted to rotate in said housing and having its shaft I4 forming an extension of or secured to the armature shaft I5 of an electric motor I 6 mounted on a stand I'I which is pivotal-i ly mounted at one end I8 upon the pedestal 6 and is secured in position by spaced studs I9, each of said studs having thread/ed engagement with the foot portion 9 and extending through an ear 20 on said stand to which it is secured by nuts 2i. The fan housing I0 has the drum casing supporting frame members 22 and 23 connected thereto by the bolts 24, the member 22 also forming a pipecoupling portion 22' cooperating with the upper end of the conduit II to being formed of sheet metal suitably joined together. The front wall 21 is of annular form and. includes the inwardly extending ring member 28. The Ishell 25 has an air inletI opening 29 formed in its upper portion and an outlet 30 in its lower 5 portion alined with the coupling portion 22'. A
, compartment 3i' is formedabove the opening 29 and has its side walls secured to the shell 25 and has a heating unit 32 mounted therein adjacent the inlet 33 to said compartment. I
The drum 8 includes a shell 34 whose rear edge f is interlocked with the beaded edge 35 of the back end or wall 36 and whose front edge is interlocked with the beaded edge 3l of the annular front end or wall 38, which has an outwardly ex- 15 tending annular lip 39 at its opening with which the ring member 28 .overlaps quite closely so as to prevent clothes getting caught between the drum and its casing. The shell 34 of the drum is perforated and spaced a short distance from the 20 enclosing casing and to prevent free passage of the flowing air to this whole space, exible sealing flaps 40 are secured to the casing adjacent the opening 29 and similar flaps 4I secured to said casing adjacent the outlet 30 so that the 25 heated air is drawn into the drum at the top and removed by the suction fan I3 from the lower portion of the drum.
A spider 42 is secured to the wall 36 of the drum, as by riveting, and has a shaft portion 43 30 extending from its center and journalled in ball bearing iournals 44 mounted in a frame member 45 secured to the rear'wall 26 of the drum casing l.
The drum 8 is reinforced by the transversely 3" extending radially disposed bolts 4G connected at one of their ends with the ends of the arms of the spider 42 and at their other ends with the wall 38 and these bolts also form supports for the inner edges of lifting ribs 41 mounted within the 40 drum. Each of the lifting ribs 4l is formed of a piece of sheet metal which is medially bent so as to fit around a bolt 46 and its outer edges are provided with tongues 48 adapted to project r through openings in the drum and be bent back 4" against the sides of said openings, each rib pro jecting radially inwardly into the drum.
The motor shaft I5 drives, through the worm 49 and worm wheel 50, a shaft 5I which carries a sprocket 52 connected by chain 53 with a 50 sprocket 54 on the shaft 43 whereby the drum 8 is driven by the motor at a reduced speed. The fact that the stand I1 may swing about its pivot I8 permits of a certain limited adjustment thereof so that slack in the chain 53 may be taken up. 55
The drum is loaded and unloaded through the opening, provided by the ring member 2l, which, when the drum is operating, is closed by the door in the form of a ilat circular disk engageable with the outer flange 56 of said ring member 28 and yieldingly connected to a supporting hinge member 51 by a spring 58 and bolt 59. 'Ihe hinge member 5l is pivotally mounted on a hinge pin 60 carried in the spaced arms of a hinge bracket 8| formed integral with or secured to the member 2B.
For locking the door in closed position. a latch member 62 pivotally connected by a pin 68 with the outer end of the hinge member 51 cooperates with the usual notched keeper 64, said latch provided with a handle portion 65 for both swinging said latch and moving said door.
With the above construction as the drum is revolved, the clothes are tumbled about therein and are subjected to the current of heated air passing through the drum as it turns.
The clothes are put in and taken out of the same opening and no braking or other special .operations employed Onlarger equipment is required. The operator may readily determine the condition of the clothes in a moment by. simply opening the door and feeling of them. For large laundries, a number of these units may be used in place of the single large and costly multi-pocket machines and provide a more iiexible equipment and thus eii'ect savings in operating costs.
We desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts' except in so far as such limitations are included in the claim.
What we claim as our invention is:
In a device of the character described, the combination 'of a casing, a perforated drying drum mounted to revolve in said casing and having radially disposed lifting ribs and an opening centrally disposed in one end and having an outwardly extending flange, said casing having an opening alinedl with said opening in said drum and having an inwardly extending flange projecting into said outwardly extending flange, a closure for the opening of said casing, means for circulating drying air currents through said drum. and means for rotating said drum.
