Definitions

  • One object of the present invention is to obtain a better washing of the linen and to this end the washing drum which is made of 80 perforated sheet metal as usual, is arranged so as not to dip into, the liquid contained in the outer casing or jacket, and it is provided at its periphery with a setof buckets having .an extension running radially towardsthe center of the drum, which buckets, during the rotation of the drum, take. water from the jacket andpour it over the linen through the perforations of the drum, sothat the linen is treated by aspersion or sprinkling and not by ebullition or effervescent-like seething.
  • Another object of the invention is to make the charging and discharging of the machine so that the linen can be charged from said longitudinal axis;
  • Another object of the invention is to do awaywith the usual 'separate'heating apparatus and to this end the frame of the machine supporting the stationary jacket is shaped so as to form the heating casing.
  • Said casing is ,U-shaped and double Walled surrounding a hearth or gas chamber containing a heat source.
  • the casing performs a double function of heating casing and support.
  • Figure l is a cross section of the machinecorresponding to the line 1-1 of Figure 2;
  • Figure 2 is a vertical section through the Figure 3 is a horizontal section corresponding to the line 111111 of Figure 1;
  • Figure 4 is a diagram of the controls
  • Figure 5 is a vertical section of the automatic reversing mechanism for reversing the rotations of the washing drum
  • FIGS 6 and 7 are two details of Figure 5.
  • the machine illustrated comprises a stationary jacket 1, preferably cylindrical, forming a water tank one of the faces of which has a central opening 2.
  • Circular angle pieces 1' join said jacket 1 and the faces thereof.
  • This acket is arranged upon a dou- 'ble-walled casing 3 0f horse-shoe shape ( Figure 3) the space between the Walls being filled with water and constituting a heating device.
  • the inside 4 of the said casing forms a hearth for burning any solidor liquid fuel.
  • double-wall casing 3 possesses at its base a cold water supply tap .5 and, an emptying 0 plug 6 and, at its upper part, it has a pipe abutting upon the top of the fixed jacket 1.
  • I An auxiliary tap 8 enables water heated by the radiations of the hearth to be collected.
  • the Washing drum 9 pulleys 17 and 18 one of which drives by buckets 10 and 10* each having a symmetrical form in relation to its own axis-in such wise as to fulfill its functions in both directions in which the drum rotates.
  • These buckets .10 and 10* are formed by plain solid nlatesheld in place by means of stays 11 between the cheeks 12' and 13' of the drum.
  • the set of buckets 10 which are intended to deliver washing liquid onto the linen, have extensions 10 running radially towards the center line of the drum, said extensions penetrating into corresponding deep longitudinal grooves 9*" of the washing drum.
  • the other set of buckets- 10, placed between buckets 10 have no radial extensions and to said buckets 10 correspond shallow longitudinal grooves 9 of the washing drum. The function of these buckets of different shape, will be explained later on;
  • FIG. 1 On one side of the jacketl there is fastened a bracket 14 upon which there is mounted a pulley block as well as an automatic device for reversing the direction of rotation of the washing drum.
  • This mechanism may be of any known type; Figure 5 represents a special arrangement which is particularly adapt- .able to the present machine.
  • the machine is driven by a motor 15 ( Figure 4) connected by belting, silent chain or the like to the pulley 16 of' the pulley block.
  • On both sides of the pulley 16 there are two smaller means ofstraight-belting and the other by crossed belting two pulleys 19 and 20 mounted loosely upon the shaft 21 of the drum, and
  • the shaft 21 is hollow and contains asliding'rod 25 traversed diametrically by the 'key 26. This later passes through a groove 27 made in the shaft 21 and having a length slightly greater thanthe distance of travel given to the key.
  • the mechanism for producing the alternating sliding movements of the rod 25 and con sequently thelateral displacements of the cen tral pulley 24, is composed as follows:
  • The-sliding rod 25 is connected by means of a sleeve 28 and cross h ead 29 to a counter weight lever 30 having its fulcrum at 31.
  • the shaft 21 of the washing drum in its turn,
  • a worm 32 engagin a tooth sector 33 also having its pivotal point at 31 and extending beyond this point by means of an arm 34 which moves within a recess in the counterweight lever 30, limited by lateral stops 35 and 36, so as to cause, oscillation of the counterweight as will be hereinafter described.
  • the heater 3 is also filled with water which is heated by the radiations from the hearth 4.
  • the linen is introduced at the end through the openings 2 and 12 in the washing drum and its jacket.
  • the washingdrum rotates the buckets 10 will take liquid from the lower part of the jacket 1, raising it and pouring it through the perforations in the drum upon the linen which it contains, and which is thus moistened by sprinkling and not by a. seething, bubbling or effervescent action.
  • the turned linen falls upon the bottom of the drum, but as this bottom does ,not contain water, the friction of the linen upon itself is not deadened or decreased as is the case in the ordinary ebullition or seething machines.
  • the washing liquid is delivered practically up to the center of the drum, producing a very good aspersion of the linen. Since the other set of buckets 10 have relatively short radial extensions the water taken from the jacket 1 is allowed to enter the drum before the buckets have reached the level of the center line of the drum. Thus the water runs along the inner wall of the drum, cleaning it off from all the impurities which accumulate thereon.
  • the water already heated will be taken from the heater 3, there being imparted to the water by any means the pressurenecessary to conduct it through the pipe 7 up to the top of the jacket 1.
