To all whom it may concern:.

-Be it known that I, Join; Srnnmi, of Adelphi Iron Works, Salford, in the county of Lancaster, England, engineer, have invented new and useful. Improvements in Apparatus for Drying Proofed and Like Fabrics or Materials, of which the following is a specification.- This invention relates to apparatus for drying proofed and like fabrics or materials of the type in which the fabric is passed through a chamber containing heating and cooling elements for vaporizlng and condensing the volatile solvents contained in the I 5 fabric, or in which the vapors are collected for subsequent condensation in a separate condenser. With such apparatus there is a tendencyfor a part of the. vaporized solvents toescape from the condensing or co l-' lecting chamber at the points where the fabric or material enters and leaves the same,

due to disturbing air currents or drafts and to the motion of the fabric.

The object of my present invention is to v provide means for preventing the aforesaid ofthe form shown in Fig. 2; Fig. 4 is a sec' tional-elevation taken on theli'ne AA. and looking from the leftto the right of Fig. 3; Fig. 5 is a sectional elevation taken on the line B -B of Fig. 2, showing the jetproducing arrangement at one end-of the dry- 5 ing chamber, certain 'partsbeing omitted fort-he sake of clearness; Figs.-6 and 7 are enlarged detailed views.-

The same reference characters indicate the same parts in the'difierent figures. g In the apparatus illustrated in Fig. 1 I provide an outlet at the upper end of the chamber aand connect the same to'the inlet,

n or suction pi e of a farn'or exhausterb, and

' I rovlde' a 'acent to the pointswhere the 5 fa ric entersand leaves-the'chainber, pipes 0, d each having a longitudinal slit a series of ports -therein, so arranged as to direct the air supplied to the pipe on to the fabric e as it enters'and leaves the chamber.

-The fabric is dried by the steam heated chest or its equivalent 1g. The pipes c, d aforesaid are in-communication with the delivery pipe from the-fan or exhauster b, so that the air drawn from the chamber is circulated by the fan or exhauster back again into and through the chamber.

The suction and delivery pipes of the fan b are so arranged and proportioned that the air flowing over the cooling elements 7 travelsat but a slow rate so 'as'to insure a perfect condensation of the vapors in the air, while the -jetsat the inletto and exitfrom'the condensing .or collecting chamber are sufliciently strong to prevent any escape of vapors from the .cham'be g a. Also, the total area of the air suction aperture crapertures is so proportioned to that of the air delivery apertures, as -to insure that there shall be no tendency for air to flow into the chamber a from without, such as would re sult in a dilution of'the condensed vapors.

In the arrangement illustrated in Figs. 2 to 7 the vapors are withdrawn from the chambers a by means of pipes 72. and are conducted to a separate condenser (not shown). The gases from said condenser return to the conduit j in contact with the underside of the heating chest g. From j the gases pass by the pipe is to the chamber a-through the apertures m. The gas is projectedonto the plates 72.- (see Figs. 4,- 5, 6 and 7 which direct it onto the fabric. In Fig. 6 the directing plate at the entrance to the chamber a, is shown and in Fig. 7 the directing plate is shown at the exit from said chamber. With the arrangement above described, the gases returning to the drying chamber are heated before being directed onto the fabric, thus assisting in the drying of the latter. Having now described my invention what; I claim as new and desire t0- secure by Letters Patent is i 1. In apparatus for drying proofed and like fabrics or-materials in combination, a chamber having an inlet and outletfor the fabric, heating means for drying the fabric in its passage through said chamber, means for passing'the fabr c adjacent to. said heat-.

ing means, means for drawing off the fluid drier through a pipe 71 havinga chest-like content of said chamber and for delivering same at the fabric inlet and outlet, as set forth. 1

V 2. In apparatusrfor drying 'proofed and like fabrics or materials, in combination, a

chamber having an inlet and outlet for the fabric, heating means for drying the fabric in its passage through said chamber, means for passing the fabric adjacent to said heat;

mg means, means for condensing the vapor- I ized solvents Within said chamber, means for drawing off the gaseons content of said I chamber and for delivering same at the fabric inlet and outlet, as set forth.

3. In apparatus for drying proofed andv like fabrics or materials, in combination, a

chamber having an inlet and outlet for the fabric, heating means for drying the fabric in its passage through said chamber, means for passing the fabric through the chamber over said heating means, means for condensing the solvents vaporized by saidheating means and means withdrawing the gaseouscontent of said chamber and delivering it in jet form at. the fabric inlet and outlet,

as set. forth.

In testimony whereof I have signed my name to this specification in the presence of
