Abstract
Abstract An industrial washing machine for washing each of a continuous flow of production components in turn has a group of jets mounted in a respective manifold casing at each of one or more washing stations. Each manifold casing is hinged to fixed structure and is held in abutment with a locator stop by a toggle lever latch. Each jet is precisely located in position for use by the combination of the respective locator stop and hinge and can be swung from that position when the respective latch is released in order to facilitate access to the jets for cleaning and/or access to a production component which is supported at the respective washing station for cleaning so that, if such a production component should be displaced, relocation is facilitated. The jets in each manifold casing have a smaller diameter and longer bore than do the remaining jets in the washing section of the machine. Washing fluid fed to each manifold casing is passed first through primary and secondary filters whereas the washing fluid fed to the other jets is passed through the primary filters only.

Claim 1
Independent Claim
322 words
An industrial washing machine for washing production components, the machine comprising a housing; a washing section enclosed within the housing, the washing section including a source of washing fluid, at least one battery of jets which are mounted and located with precision at at least one washing station of the washing section and pressure fluid supply means for drawing washing fluid from said source and for feeding it under pressure to and through said at least one battery of jets; and supporting and locating means for supporting and locating each component in turn at each washing station so that each of the jets directs a pressure jet of washing fluid at a corresponding specific part of a component which is supported and located at that station by the supporting and locating means when the machine is in use; wherein the improvement comprises the provision of at least one manifold casing in which a plurality of said jets are mounted rigidly and in which a pressure fluid flow path is formed for directing to each of the jets mounted in the manifold casing washing fluid which is supplied under pressure by the pressure fluid supply means; there being locating means provided for providing precise location for each manifold casing at the respective washing station so that the jets mounted in that casing are located with precision at the respective washing station when the machine is in use, the locating means for each manifold casing comprising a respective locator stop; and releasable latching means which are provided for retaining each manifold casing releasably in abutment with the respective locator stop, the latching means being releasable to permit removal of each manifold casing from the position at which it is located precisely at the respective washing station by the respective locating means and being adapted to reclamp the respective manifold casing subsequently in the same precise position that is determined by the respective locating means.
Claim 2
Dependent Claim
322 words
An industrial washing machine for washing production components, the machine comprising a housing; a washing section enclosed within the housing, the washing section including a source of washing fluid, at least one battery of jets which are mounted and located with precision at at least one washing station of the washing section and pressure fluid supply means for drawing washing fluid from said source and for feeding it under pressure to and through said at least one battery of jets; and supporting and locating means for supporting and locating each component in turn at each washing station so that each of the jets directs a pressure jet of washing fluid at a corresponding specific part of a component which is supported and located at that station by the supporting and locating means when the machine is in use; wherein the improvement comprises the provision of at least one manifold casing in which a plurality of said jets are mounted rigidly and in which a pressure fluid flow path is formed for directing to each of the jets mounted in the manifold casing washing fluid which is supplied under pressure by the pressure fluid supply means; there being locating means provided for providing precise location for each manifold casing at the respective washing station so that the jets mounted in that casing are located with precision at the respective washing station when the machine is in use, the locating means for each manifold casing comprising a respective locator stop; and releasable latching means which are provided for retaining each manifold casing releasably in abutment with the respective locator stop, the latching means being releasable to permit removal of each manifold casing from the position at which it is located precisely at the respective washing station by the respective locating means and being adapted to reclamp the respective manifold casing subsequently in the same precise position that is determined by the respective locating means.
Claim 3
Dependent Claim
62 words
An industrial washing machine according to claim 1, wherein the locating means for each manifold casing also include a hinge arrangement by which the respective manifold casing is hinged to fixed structure of the apparatus so that, when the respective releasable latching means are released, it can be swung to and from the position in which it abuts the respective locator stop.
Claim 4
Dependent Claim
20 words
An industrial washing machine according to claim 1, wherein each locator stop is mounted adjustably with respect to the housing.
Claim 5
Dependent Claim
62 words
An industrial washing machine according to claim 1, wherein the releasable latching means for each manifold casing and the respective locator stop are supported with respect to the housing by the same support structure, there being separate support structure for jointly supporting the releasable latching means and respective locator stop for each manifold casing where there is more than one manifold casing.
Claim 6
Dependent Claim
32 words
An industrial washing machine according to claim 1, wherein the pressure fluid flow path formed in each manifold casing is connected to the pressure fluid supply means by a respective flexible pipe.
Claim 7
Dependent Claim
24 words
An industrial washing machine according to claim 1, wherein the jets that are mounted in the or each manifold casing are mounted removably therein.
Claim 8
Dependent Claim
58 words
An industrial washing machine according to claim 1, wherein said at least one battery of jets comprise at least one standard jet mounted rigidly within its own fixed support structure and the jets that are mounted within said at least one manifold casing and which are special jets having smaller diameters and longer bores than each standard jet.
Claim 9
Dependent Claim
156 words
An industrial washing machine according to claim 7, wherein said source includes a sump for collecting washing fluid drained from each washing station during operation of the machine, there being conduit means by which said pressure fluid supply means communicate with the sump and with each of said at least one battery of jets, primary filtering means through which all washing fluid drawn from the sump by said pressure fluid supply means for feeding to said jets is directed and which are adapted to separate from washing fluid passed therethrough particles of solid matter which have a size which is greater than a predetermined minimum size, and secondary filtering means through which all washing fluid that is fed under pressure to each manifold casing is directed, the secondary filtering means being adapted to separate from the washing fluid passed therethrough particles of solid matter which have a size which is smaller than said predetermined minimum size.
Claim 10
Dependent Claim
67 words
An industrial washing machine according to claim 8, wherein the pressure fluid supply means comprise a tank, one pump which is operable to draw washing fluid from the sump and to feed it to the tank via said primary filtering means and another pump which is operable to draw washing fluid from the tank and to feed it under pressure to said jets via said conduit means.
Claim 11
Dependent Claim
18 words
An industrial washing machine according to claim 8, wherein the primary filtering means comprise at least one hydrocyclone.
