To all 'whom it may concern:

Be it known that I, Gomma W. Fnonerate and of very simple, economical construction.

\ My invention consists generally in locating a baiile wall within the space inclosed by the drier, between which wall andl the outer wall of the drier a flue is provided leading to the exhaust or exit.

In the accompanying drawings forming part of this specification, Figure 1 is a perspective view of a drier embodying my invention, Fig. 2 is a vertical, longitudinal,

sectional view of the same, Fig. 3 is a detail.

view illustrating the manner of supporting the drier rack.

In the drawing, 2 represents the front wall of the drier, 3 the side walls, 4 the rear wall and 5 the top, inclosing a chamber or space 6.

7 represents a series of inverted T rails,

the horizontal flanges-of which form supports for the wheels 8 on hangers 9 to which the racks 10 are secured. These racks are equipped with the usual rods 11 on which the garments to be dried are hlmg. The racks have the usual face plates 12 closing the upper portion of the front wall of the drier in the usual manner and the outer ends of the rack supporting rails are provided with posts 12, of suitable construction. These rack supporting rails form substantial supports for the rack hangers and permit the racks to be moved easily back and forth in the drier, even when `filled with clothes. Any other suitable form of bar may be used in' .place of these T-bars, if preferred.

The lower portion of the wall 2 has a draft opening 13 and a door 1 4 therefor, and in the lower portion of the chamber 6 I provide a radiator 15 supported on bars 16 and connected with a suitable source of heat, such as steam or hotl water, preferably the former. In. the rear of the racks I provide an upright baille wall 17 extending parallel with the rear wall 4 to a pointnear the top 5, a throat or passage 18 being formed between said wall 17 and the top 5 leading to a diving flue 19 that is formed between the walls 17 and 4, and extending transversely of the chamber 6, preferably from the top to the bottom thereof. The lower portion of the chamber 6 has a pipe connection 19, extending preferably out through the wall 3 and communicating with awaste or discharge pipe 20. The outer end of the pipe 19 has aclean-out thimble 21 'capable of removal to obtain access to the pipe 19', and supply and return pipes 22 and 23 are conduct-ed through the wall 3 of the drier to the radiator.

As indicated in Fie'. 2, a circulation of air will be established through the opening 13 and up through the radiator and the racks and down the flue 19 to they exhaust pipe. The baffle wall will separate the damp and heavy air from the fresh and heated air used in drying the clothes. Furthermore,

a suction will be established in the diving iue 19 which will hasten the circulation of air through the chamber 6 and cause the currents of air to ow faster through and among the garments hanging therein without drawing any of the fresh and heated air before it is laden with'moisture.

By regulating the size of the opening 13 the degree of the draft through the chamber can be modified as desired. Y v

I have shown a radiator coil located in the chamber 6,but do not confine myself to this means of heating the chamber, as any other suitable apparatus may be used in place of it. v

In driers as 'generally constructed, the warm air, rising and passing between the clothes, becomes saturated with the moisture therefrom and drops back to the lower portion of the drier, to be again heated-and lifted Vamong the clothes. This operation continues, the moisture -being dried out of 'the air as it falls, but the soapy matter remaining in suspension and being deposited upon the clothes until, althoughthe mois ture may be removed from the garments,

they will have a stiff, soapy feeling, which isL peculiarly incidental to the drying of clothes in an ordinary drier. With my diving flue construction this objection is avoided. 'Ihe` warm air rises .among the clothes, gathers up thelmoisture therefrom and passing over the partition wall drops down to the bottom of the iue 19 and passes out through the exhaust pipe, While a fresh supply' of air enters and is heated and discharged, among the clothes. The partition prevents the descend ing currents of moisture laden air from owing back among the coils of the radiator and rising again among'the clothes. The result' is that when the arments are dried they will be soft and iiexible and that greasy, starchy feeling so often found in clothes dried in a laundry drier,

will be entirely absent. The partition positively prevents the moisture laden air from returning to the heater and insures a rapid circulationl of the air through the drier.

I claim as my invention: A

1. A laundry drier comprising a casing having a heating chamber inclosed by said casing and a heating means therefor and an air inlet in its lower wall, a baille wall provided within said casing vand extending vertically therein from the floor of said casing to apoint near the top thereof, saidbaiiieV wall being spaced from one of the upright 'walls of said casing to form a descending ue, the space between the upper portion of said baffiewall and the topof said casing forming an inlet opening to said flue)drying racks arranged within said cham er between. said air inlet opening and the opening leading to saidV descending flue, said heating means operatingV to heat the air entering saidinlet opening as it ascends with# said chamber and before it reaches said drying racks, said descendin I yiiie being closed at the bottom and provi ed in one of its sidewalls with an exit opening extending outwardly through said casing, slib.-

stantiallyv as described.'

i ,2. A laundry ldrier comprising a, casing having a heating chamber andan' air inlet opening in its lower wall, drying .racks 1n the upper portion of saidchamber and heatling means interposed between said drying racks and said air inlet opening, the cur.- rents of air from said inlet. opening being compelled to circulate around -said heating means before reaching said racks," said heat ing chamber having a vertically arranged descending flue communicating with the upper portion of said chamber, lthe heated air being com elledto pass through said racks before reac ing the inlet opening to said descending flue, the lower walls of said descending iiue having an exit opening andI a pipe therefor leading outside said casing, a circulation being established in said chamber upwardly through sa-id racks and downwardly through said descending flue and throuohsaid exit opening to a point outside said'c amber. y

In witness whereof, I have hereunto set my hand this 29th day of October 1909.
