Application flled 'February 2, 1988. Serial No. 616,588.

To all 'whom it may concem:

Be it known' that I, CHARLES L. BnAmY, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Laundry Driers, of which the following is a specification.

This invention relates to improvements in laundry driers.

The main objects of the invention are:

First, to provide an improved laundry drier by means of which laundry may be very rapidly dried 'and treated with cold fresh air.

Second, to provide an improved laundry drier which is of large capacity and simple and compact in structure.

Third, to provide an improved laundry drier inwhich the dried articles are sub.- jected to but little wear.

Fourth, to provide an improved laundr drier whichl produces substantially the e fects of open air drying.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish'the objects of my invention byv the devices and means described in the following specification. The invention is clearly defined "and pointed out in the claims.

A structure which is' apreferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which: i

Fig. I is a frontelevation of a structure embodying the features of my invention, parts being shown conventionally and parts being sectioned and broken away ;for convenience in illustration.

Fig. II'is 'an end view looking from the left of Fig. I with parts broken away for convenience in illustration.

Fig. III is a transverse section on a line corresponding to line 3-3 of Fig. I.

Fig. IV is a front elevation partially in 'Vertical central longitudinal section of a modified form or embodiment'of my invention.

In the drawing similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing, I provide a. cylindrical casing 1 mounted upon suitable standards 2 and having a door 3,| the casing when the door is closed being substantially an alr-tlght casing. Within this casing is a drylng cylmder 4 having a side door 5 and end walls 6. In the preferred embodi-' i rsiderable size it is preferably provided with foraminate partitions 9.

At the bottom of the casing is an air open- .mg 10 connected by the conduit 11 to the blower 12. This blower is connected to the heater 13, there being a cold air passage or conduit 14 Controlled by the gate valve 15 so that either 'heated or cold air .may be dehvered by means of the blower 12.

I also preferably provide a blower 16 which is connected by the conduits 17 to the tubular bearings 8 although, if desired, either one of these blowers 'may be omitted with satisfactory results or either one may -be cut out of operation, if desired.

' The drying cylinder is driven from the motor 18, the driving shaft of which is prof vided with a pinion 19 meshing with a gear 20 which infiturn meshes with the gear l21 secured to the drying cylinder.` This drives the cylinder at a relatively low speed. I

preferably p'rovide gasket or packing members 22 which are disposed in a spaced relaton' longitudinally of the casi'ng to coact with the cylinder, providing a longitudinal passage 23 into which the conduit 1.1 opens. These packing or gasket members 22 confining the air within this passage compels it to pass upwardly through the lower portion of the cylinder or outwardly therethroughacair to ass upwardly or downwardly around the cy inder. In vany event, with this ar- 'cording to the direction of the current of i rangement of conduits, the one opening within, the cylinder 'and the other,- within the casing, the air must pass through the cylinder and is eflFectiveIy brought into con' taet with the articles as 'they are gentiy tumbled or stirred about by the'rotationof the casing.

In the modified form of my inventlon shown in Fig. IV the blower 24 is connected with the heater 25 and to the cylinder througha tubular journal and the 'tubular bearing ofthe character shown in Fig. I, the other journal 26 being a solid journal.

The air conduit 27 is connected tothe end of the casing opposite the tubular journal so that the air is compelled to pass through the cylinder. In this modification the blower may be reversed and the air would pass in the opposite direction.

My improved drier is of very large capacity. The laundry is rapidly and efl'ectively dried and has the fresh attractive quality of laundry dried in the open a1r.

I have illustrated and described my improvements in embodiments which I regard as very satisfactory. I have not attempted to illustrate or describe various other embodiments or adaptations which I lcontemplate'as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a laundry drier, the combination of a cylindrical casing provided with tubular bearings, a drying cylinder having a foraminate peripheral wall and having tubular journals coacting With said tubular bearings providing air passages opening to the interior of the drying cylinder, said drying cylinder having spaced transverse foraminate partitions therein, members disposed longitudinally of said casing to coact with said cylinder providing a longitudinal air passage below the same, air conduits connected to said tubular bearings, an air conduit connected to said air passage at the bottom of' said casing, meansl for driving said cylinder, and blowers for circulating air through said conduits, all coacting for the purpose specified.

2. In a laundry drier, the combination of a casing, a drying cylinder having a foraminate peripheral Wall and having tubular journals providing air passages opening to the interior of the drying cylinder, members disposed longitudinally of said casing at each side of said inlet to coact with the periphery of said cylinder providing a longitudinal air passage below said cylinder, air conduits connected to said tubular bearings, an .air conduit connected to said air passages at the bottom of said casing, means for driving said cylinder, and a blower connected to one of said conduits so that the air is caused to pass through said cylinder.

3. In a laundry drier, the combination of a closed cylindrical casing, a drying cylinder having a foraminate peripheral wall and a tubular journal opening wlthin the cylinder, members disposed longitudinally of the casing to coact with the cylinder providing a longitudinal air circulating passage of which the cylinder constitutes the inner wall, and air circulating means connected to deliver to said passage and discharge through the journal.

4. In a laundry'drier, the combination of a casing, a foraminate cylinder rotatably mounted within said casing, an air passage opening to said cylinder axially thereof, members disposed longitudinally of the cas- 'ing coacting with the cylinder providing a longitudinal air passage of which the cylinder constitutes the inner wall, and a blower connected to one of said passages so that the air passes through said vcylinder to escape by the other passage.

5. In a laundry drier, the combination of a casing, a drying cylinder having a foraminate peripheral wall and having tubular journals providing air passages opening to the interior of the drying cylinder, said drying cylinder having spaced transverse foraminate partitions therein, air conduits connected to said .tubular bearings, an air conduit connected to the bottom of said casing, means for driving said cylinder, and an air circulating means connected to one of said conduits, all coacting for the purpose specified.

In witness whereof, I have hereunto set my hand and seal.

CHARLES L. BRALnY. [a 8.]
