Definitions

  • Il -H I 80 United States Patent C
  • the present invention concerns a machine used for chemically cleaning textiles, for example, garments, which are disposed in a rotating drum provided peripherally with bores or slots, whereby through the:bores or slots solvents are at first introduced and discharged and subsequently drying air passed through the materials for cleaning.
  • the invention consists in the fact that from a compressed air pipe directed against the drum periphery,
  • an air injection pipe there is branched a pipe having a considerably taperingcross section, which leads along the housing wall of the cleaning machine to the charging door andthere is directed. against a deflecting element which deflects the air issuing at high speed axially into the drum.
  • the branch pipe preferably branches off in the manner of a siphon pipe, whereby both cross sections are equal at the junction. It is also possible for the branch pipe to be connected already at the blower. In some instances it is also fitting for each pipe to be connected to a blower, whereby this rather costly procedure is of particular advantage if the air supply in one pipe, for example the one which injects the air radially into the drum, is to be throttled back or to beset at zero.
  • the collar-like enlargement of the annular flange to enclose the frame of the inspection glass of the charging door and be provided with any desired number of closely located air inlet apertures, for example, slots or bores, the cross section of which is conveniently smaller than buttons, bucklesand the like to prevent the latter from being caught in the openings.
  • the front edge of the collar-like enlargements of the ring flange to be drawn forwardly to near the mounting of the charging door.
  • the air streaming axially into the drum from the branch pipe causes the material to be cleaned to be pushed away from the charging door and causing the material to be cleaned which is carried along by the periphery of the rotating drum to execute a" tumbling movement, which material finally drops again due to its weight and thus gets into the axial air'stream which forces the individual textile articles to be turned.
  • This turn may according to the invention also be brought about ice in that the ring flange has an annular enlargement projecting into the interior of the drum, against which the textile articles strike when the drum is rotating and therefore tend to tip over. It is possible in particular for the ring flange to be removably mounted on the front I wall of the drum.
  • the drying time and intensity is substantially increased by the fact that as soon as the drum starts to rotate a negative pressure sets in, caused on the one hand by the suction pipe of large cross section and on the other hand by the branch pipe having asmall cross sectional area and thus causing an increased resistance, and furthermore due to the sealing effect of the'articles to be cleaned lying against the openings formed in the drum periphery. It is also possible for several branch pipes to be provided directed from different directions relative to the deflecting means.
  • the effect of the axially directed additional air stream may moreover be increased also by a special design of the drum inlet opening.
  • the object of the annular enlargement projecting into the drum according to the invention is to deflect the articles being dried revolving therein from the charging door during the rotation of the drum, so that there is as little friction as possible and wedging effect between the articles to be dried and the wall of the housing.
  • bit is possible by way of branch pipes and possibly with the drum axis may be of any constructional design,'
  • Fig. l is a horizontal section through a party of the cleaning machine with the drum, charging door and air pipes;
  • Fig. 2 is a section taken on the line Ila-II according to Fig. l but on a smaller scale.
  • the drum 1 of the cleaning machineshown-in section is mounted unilaterally in the bearing 2 of the housing 3 of the cleaning machine in the same manner as hitherto known arrangements. Arranged around the .drum 1 .is
  • the branch pipe 6 leads in atthe shoulder 7' projecting in the direction towards the drum 1 of the seat 7 for the charging door 8 in which there isaprovided an inspection glass 9.
  • a bore 10 which corresponds approximately tothe inner cross section of the branch pipe 6.
  • the air passing. through the branch pipe 6 thus arrives through the .bore 10 on to the frame 8 of the inspection glass 9 ofthe charging door 8 from where it is deflected axially in the direction towards the drum 1 and gets into the interior of the drum 1 through the charging opening 1".
  • the frame 8' is drawn forwards in the direction towards the drum 1 and of conical design. It isof course also possible to provide differently designed and constructed deflecting means in place of the frame 8.
  • the drum 1 has an annular flange 11 at the charging opening 1", the collar-like enlargement 11' of which projecting in the direction of the seat 7 of the charging door-extends closely past the mounting 7, thus preventing .the garments contained in the drum from becoming wedged between the seat 7 and the collar-like enlargement 11'.
  • This collar-like enlargement 11 has openings 12, such as slots, holes and the like distributed over the whole periphery thereof through which the air issuing from the branch pipe 6 passes.
  • the air striking the material of the annular enlargement 11 between the openings 12 1 range of the air entering through the charging opening 1" so. that in addition to. the turning movement caused by the drum they are additionally subjected to a transverse turn. Due to this tumbling movement all parts of the articles to be dried are in fact in contact with the air stream, thus causing a'substantially more favourable drying time and intensity than in known apparatus.
  • a a 1.1m a machinetor the chemical cleaning of textile art-icles such: as garments, a rotary drum having aperipheral Wallperforated for passage of solvent andsubsequentlyf of drying air therethrough, a fixed housing roundingsaid drum and having a peripheral wall spaced from the peripheral lwall of said drum, said drum andsaid housing eachhaving an end wall and-a door.
  • the openings 12 have a cross section which is smaller than buttons, so that garments cannot be caught therein.
  • the distance between the front edge 11 of the collar-like enlargement 11' and the seat 7 of the charging door 8 is very small, and the front edge 11" is remote from the drum charging opening 1" hence preventing any textile articles from getting into the region .of the parting. line.
  • the function of the cleaning machine is evident from Fig. 2.
  • the articles to be dried contained in the drum '1 during the rotation of thed-rum are carried along by said air supply pipe between sadi end walls towards said door-apertures, a discharge pipe connected to the pe-- r pheral wall?
  • said, housing diametrically opposite said air supply pipe and overtheperforated-peripheral wall of the. rotary; drum, and a door having--21- coniform peripheral surface and being adapted to fit the door aperture of the housing and to project into the door apertureoi? the drum, the branch pipe being positioned SO ⁇ as to dlscharge air on to-the conifonnpdoorsurface and: thence to deflect said; air intothe. drum.
  • a structure according to. claim 1L including a door seat definingtheldoor aperturein. the housing and presentwhereby annularchamber is formed between said flanges. for distributing air dischargedby said'bra-nch: pipe.
  • a rotary drurn having a periphera-l wall. perforated forpassage, of solvent and subsequently. of drying air therethrough, a fixed housing surrounding said and having. a peripheral: wall spaced from the. peripheral: wall. of said: drum, said drum andsaidt housing each. having an end wallzand a door:
  • the housing including a door'seat defining the. door aperture in the. 1
  • housing andpresenting an inwardly: projecting generally cylindrical: flange having. a bore. therethrough, the drum haying'a. door collar defining. the door aperture the drumf and. presenting a generally cylindrical flange. of smaller diameter than the flange of said seating.
  • a branch pipe tapering to a reduced cross section extendingfrom said air supply pipe between said endwa-lls to wards saiddoor apertures, and term-inating'ad-jacent said flange bore, a discharge pipe con-nectedto the peripheral wall of said housing diametrically opposite said air supply pipe and over the perforated peripheral Wall of the rotary drum, a door having a coniforrn peripheral surface and being adapted to fit the door aperture of the housing and to project into the door aperture of the drum, and means for directing air discharged into said chamber from the branch pipe on to the coniform door surface and thence to deflect said air into the drum.
  • door collar flange has an inwardly directed toroidal portion.
