APPARATUS FOR IMPREGN'ATING AND nx'rmrc'rme mourns- FROM FABRICS.

Patented June 8, 1909.

. Application filed November 20, 1907. Serial No. 402,969.

To all whom it may concern: I Be it known that I, HARRY HEY, a subject of the King of Great Britain, residing at Dewsbury, 1n the county of.York,-'in the Kingdom of En land, chemist, have invented certain new an Relatin%)to Apparatus for Y 'Vashing,

rymg', or Extracting'Li uids from Fabrics and other Goods, for whic application has been made in Great Britain, No. 26,843, dated November 26, 1906.

This invention relates to centrifugal machines, and especially to apparatus for carrying out the processes of impregnating, drying anddextractlng liquids from fabrics and other goo s.

Amon theJobjects of my. invention are: to provi e an apparatus in which the goods ated with a volatile liquid or solvent an fluence' of a vacuum; to provide an apparatus in which the hi h speed necessary can be obtained without anger tothe ap. aratus, and Without detracting from the e ects-required to arrange the door of the casing, in which the-cage rotates, in such a position that access can easily be'had and so that the tendencyof the centrifugal force set up by the rapid rotation will keep the doors of the cage closed and thus avoid any twisting action; and to arrange the door of the casing so that it can be moved away quite clear of the orifice which it closes.

In the accompanying drawings: Figure 1 shows a side v1ew of the apparatus as a whole; Fig. 2 is a detail plan view in partial the ca eat diflerentspeeds.

section of the door of the casing. and its supports; Fig. 3 is an e e'v'ation' in partial section of half the cage removed from its casing and Fig, 4is an elevation showing half the casing and cage'in section, and'the gear for rotating In t e drawings, the casing a is supported in any-suitable manner and eld stationary, and contains a rotatable cage 6, haying a number of sector shaped; compartments 0.

end thereof away from the gearing hereinafter referred to, while thedooi' e. of each compartment of the cage isar'ranged so as to .be capable of being brought.- opposite the door in the casing. These doors e are ar Y ranged with their hinges. ef between their mner edges and the center of the cage, so

that said doors will tend to close as the cage I rotates. Further, the hinges are arranged useful Im rovements in or Impregthen dried under the inright-angles to a diameter of the cage.

fare strengthening bands on the periphery so that the door-can turn about a line at links 7' on the casing, and by means of the screwlc to press the door 11 against the casing, and; so hermetically close the orifice h. 1 represents the end of the casing and m strengthening ribs thereon.

n is a fast and loose pulley-device," the shaft of which carries a spur-wheel 0 which gears with a'further spur-wheel p, this spur-wheel p carrying one'member'of a clutch q, carried osely on the shaft 1", journaled in the casing, the other member of which is carried by pulleys, fixed on shaft r, to which the cage is'fix'ed so as to journal in the casing. tie a suitable connection from the casing a tea suitable vacuum-pump u. and o represents, diagrammatically, a volatile vapor and air separating device interposed between the pump a and the casing.

The cage 1) is divided into the sector-she, ed compartments 0, for the pur ose of enab ing the fabric, or other goo dst0' e treated, to be substantially uniformly distributed in the cage, this being important since in the rapid rotation of the cage, in the absenceof said compartments, the tendency would be to throw the work into a mass at one point in the circumference of the cage and thus unbalance and subject the apparatus to'irregular strains and render it liable to accident; also, the work in such mass. would not be.

thoroughly or properly impregnated and could not be properly and thoroughly; dried, nor the solvent expelled from the cage. By distributing the. work in com" partments of the cage, balance of the latter is maintained,impregnation of the work becomes thorough and uniform, the work is quickly dried, and the solvent is completely expelled so that its recovery is complete: The periphery of the cage is, of course, foraminous, rendered so in this instance of my invention b a scriesof parallel cross-barsj" Wor orthesecured to t e'strengthening bands and arranged slightlyseparated to permit-the solvent to properly properconditions of operation.

pass in. and out under the By arranging the doors e, of the cage-compartments c, at the side instead of on the periphery of the cage, the powerful centrifugal force cannot tend to cause them to fiy open, but will tend tokeep them closed, this being a very important feature in my apparatus; and this arrangement of the doors e, in cooperation with the arrangement of the door (1 inthe side of thecasing, enables the several compartments of the cage to be quickly and handily filled-through the casing. This, arrangement is rendered still more eifective by hangin the door (1 of the casing remote from the ori ce 71., as shown in Figs. 1 and 2, since the said door can be swung clear to one side away from any possibility of interference with the operation of filling the cage through the registering doors (1 and c. These various arrangements of parts add the important advantage to the apparatus of enabling it to be.

driven at much greater speed, because the cage and casln can be made of much larger diameterand s orter axial length. This directlyresults in the important function of economy in operation, since the cage must always be filled with solvent to a certain predetermined height and the recovery of the solvent is in direct proportion to the speed of the apparatus.

In operation, the goods are placed in the com artmentc of the cage 1), through the orifree in the casing, and the clutcharts g and 8 brought into engagement,so t at the pulleys 'n, which are rotated from any source of power, will cause the rotation of the cage through the spur-wheels o and p at a slow speed. This slow speed of rotation of the cage is carried on until the goods are thoroughly impregnated with the liquid,-introduced into the casin then the clutch q is dis engaged and the siaft 1' rotated directly from the source of power by means of the pulley s, whereb a high speed of rotation is setup. When t 's high speed of rotation is set up, the vacuum-pump a is also set in action, so that the casing a is placed under a vacuum and the centrifuging therein takes place under vacuum, whereby the drying or extracting of the liquids from the goods is brought about not only by the centrifuging,

but also by the liquid being forced out of the goods, a casing having an orifice at one end, a

goods owing .to the vacuum set up.

I declare that what I claim is:

1. In apparatus for impregnating and drying or extracting liquids from fabrics or other goods, a casing,-a door at the end of the easing, a rotatin cage within the said .easing having a lura ity of compartments, doors on the end 0 the said cage arranged one for each com artment so as to register with the door of t e casing, and means for rotating the cage. v

2. Inapparatus for impregnating and drying or extracting liquids rom fabrics or other bracket hinged on the said casing remote from said orifice, a door on said hinged bracket corresponding to the orifice in said casing, means for clamping saiddoor on the said casing, a rotatable cage within the said casing, doors at the end of said cage for registering with the orifice of the casing, and means for rotating the cage.

3. In apparatus for impregnating and drying or extracting liquids from fabrics or other goods, a casing having an orifice at the end, means for closing the said orifice, a cage rotatable within the said casing, compartments in said cage, a door at the end of each of the said compartments, for registering with the orifice of the casing, hinged so as to turn about lines at right-angles to the diameter of the cage, and means for rotating said cage.

4. In apparatus for im regnating and drying or extracting liquids f fom fabrics or other goods, a casing having an orifice at one end, means for tightly closing the orifice in said casing, a cage rotatable within the said casing, doors at the end of said cage for registering with the orifice of the casing, hinges turning about lines at right-angles to the diameter of the cage for holding the doors on the cage and arranged on the side of the doors nearest the center of the cage.

In apparatus for impregnating and drying or extracting li uids from fabrics or other .goods, a casing, a oor at the end of the easing, a rotatin cage within the said casing having a plura ity of compartments, doors on the end of the said cage arranged one for each compartment so as to register with the door of the casing, means for rotating said cage, and means connected to the casing tending vto produce a Vacuum therein whereby the work is lmpregnated and the solvent expelled under the influence of centrifugal force and a vacuum.

6. In apparatus for impregnating and drying or extracting liquids from fabrics and other goods, a casing, a door at the end of the casing, a rotating cage within the said casing having a lurality of compartments, doors on the end oiithe said cage arranged one for each compartment so as to register with the door of the casing, means for rotating said cage at two different speeds, and means connected to the casing tending to produce a vacuum therein, whereby the work' in the cage is thoroughly impregnated during the rotationthereof at one speed and the solvent is expelled from the cage during the rotation thereof at another speed and also under the influence of a vacuum.

In witness whereof, I have hereunto signed my name this 6th day of November 1907, in the presence qf two subscribing witnesses.
