CHARLES L. BRALEY, OF CHICAGO, ILLINOIS, ASSIGN OR OF ONE-HALF TO CHARLES F. NOFTZGER, OF CHICAGO, ILLINOIS, AND ONE-HALF TO THE AMERICAN LAUNDRY MACHINERY COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

. LA NDRY DRIER.

Application filed February 2, 1923. Serial No. 616,58'7.

7 '0 all whom it may concern:

Be it known that I, CHARLES L. BRALEY, 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 the laundry may be effectively dried and treated with cold or fresh air.

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

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

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

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

Fig. I is a front elevation of a laundry drier embodyin the features of my invention, the parts eing shown in vertical section and parts being broken away for convenience in illustration.

Fig. II is an end elevation looking from the left of Fig. I with parts shown in section and parts broken away for convenience in illustration.

Fig. III is a transverse section through the drying cylinder on a line corresponding to line 33 of Fig. I.

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

Referring to the drawing, I provide a frame comprising end members or pedestals 1, 1 connected by longitudinal members 2. These pedestals are provided with tubular bearings 3 for the tubular journals 4 of the drying cylinder 5, thus providing air conduits opening into the ends of the cylinder. The cylinder is provided with a door 6 and when the door is closed it is substantially or approximately air-tight. The cylinder is preferably provided with transverse foraminatc partitions 7. The blower 8 is connected to deliver to one of the tubular hearing 3 while a discharge conduit 9 is provided for the other. The blower intake is connected with a heater 10 and also an air conduit 11 for fresh air. The damper valve 12 is provided to cut off either the cold air conduit or the heater conduit.

The cylinder is driven from a motor 13 having a pinion 14 on its shaft meshing with a gear 15 which in turn meshes with the gear 16 on the cylinder. This connection drives the cylinder with a slow movement so that the laundry or clothes ithin it are agitated or carried up the side and fall back, that is, the cylinder should not be driven with such speed as to hold the clothing to the wall of the cylinder. The air delivered to one end of the drying cylinder is discharged at the other so that it comes into contact with the laundry being dried, ra

idly drying the same and discharging t e moist air. The foraniinate partitions prevent the laundry from being carried or bunched at the air discharge end of the cylinder by the blast of air passing therethrough. The laundry in the separateco-mpartments is kept separated and as it is carried around the cylinder will fall at different periods and in different conditions, depending upon the amount and weight of the material so that the tendency for the air to form currents at one side is overcome, and further, the fo-raminate partitions themselves serve as a means to that end, so that a maximum contact of the air with the laundry is secured.v

In practice hot air is first delivered and then cold air, which secures results very much like the drying of clothes in open air and sunshine. The clothing comes from the drier soft and free from wrinkles.

I I have illustrated and described an embodiment which is simple and economical in structure. I have not attempted to illustrate or describe other modifications or adaptations which I contemplate, 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. Y

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 supporting frame provided with tubular bearings, a drying cylinder having tubular journals coaoting with said tubular bearings,

0 said journals opening within said drying cylinder, spaced foraminate partition Walls in said cylinder, means for driving said cylinder, and a blower connected to deliver" xto one of said tubular bearings and a dislu charge conduit connected to the other.

2. In a laundry drier, the combination of a drying cylinder having tubular journals providing conduits opening within said drying cylinder, spaced foraminate partition walls in said cylinder, means for driving said cylinder, and a blower connected to one of said journals.

In Witness whereof, I have hereunto set my hand and seal. 7
