Abstract
Abstract Apparatus for supporting and connecting fluid control and/or conditioning units such as air filters, lubricators and pressure regulators to permit flow of fluid through such units in series. The apparatus is of a kind employing supporting frames in which the units can be inserted to bring inlet and outlet ports of the units into sealed registration with peripheral openings in the frames. To enable frames to be connected in series into a fluid line without the need to interpose a linking conduit, insert components are provided for insertion through peripheral openings of the different frames. When the frames are assembled in series these insert components co-operate to provide a fluid path from a unit in one frame to a unit in the next frame.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
In apparatus for supporting and connecting fluid control and/or conditioning units to permit flow of fluid through such units in series wherein said apparatus includes at least one pair of frames each capable of supporting at least one of said units in a position so that fluid inlet and outlet ports of each said unit are within the frame, each of said frames having local peripheral openings via which fluid can flow to and from a unit located in said frame, the improvement comprising: at least one pair of tubular insert components which are insertable through two of said peripheral openings, one in one frame and one in the other frame, said insert components having: sealing faces for co-operating with sealing faces of said units in said frames; and co-operating means to provide a fluid path from a unit in one frame to a unit in the other frame.
Claim 2
Dependent Claim
149 words
In apparatus for supporting and connecting fluid control and/or conditioning units to permit flow of fluid through such units in series wherein said apparatus includes at least one pair of frames each capable of supporting at least one of said units in a position so that fluid inlet and outlet ports of each said unit are within the frame, each of said frames having local peripheral openings via which fluid can flow to and from a unit located in said frame, the improvement comprising: at least one pair of tubular insert components which are insertable through two of said peripheral openings, one in one frame and one in the other frame, said insert components having: sealing faces for co-operating with sealing faces of said units in said frames; and co-operating means to provide a fluid path from a unit in one frame to a unit in the other frame.
Claim 3
Dependent Claim
54 words
The improvement as defined in claim 1, wherein: said pair of insert components are insertable into operative position from the insides of said pair of frames through said peripheral openings thereof, said insert components having inner end flanges which provide said sealing faces for co-operating with sealing faces of said units in said frames.
Claim 4
Dependent Claim
42 words
The improvement as defined in claim 2, wherein: said sealing faces provided by said inner end flanges are inclined depthwise of said frames so that units with similarly inclined co-operating sealing faces can be held tightly in said frames by wedge action.
Claim 5
Dependent Claim
37 words
The improvement as defined in claim 1, wherein: said co-operating insert components and the frames are formed so that when said co-operating means of said insert components are in engagement said frames abut one against the other.
Claim 6
Dependent Claim
20 words
The improvement as defined in claim 1, wherein: said co-operating means of said components are engagable with one into another.
Claim 7
Dependent Claim
41 words
The improvement as defined in claim 1, wherein: means is provided to lock said pair of co-operating insert components in said pair of frames; and means is provided for clamping said frames together to hold said co-operating insert components in engagement.
Claim 8
Dependent Claim
57 words
The improvement as defined in claim 6, wherein said frames have peripheral wall portions and further including: holes in at least one said pair of frames located in said peripheral wall portions; and clamping bolts for clamping the frames one against the other extendable through said holes without obstructing the movement of said units into said frames.
Claim 9
Dependent Claim
38 words
The improvement as defined in claim 7, wherein: said peripheral wall portions are formed on the inside faces thereof with recesses or channels for accommodating nut members and holding them against rotation during screwing of said bolts therethrough.
Claim 10
Dependent Claim
56 words
The improvement as defined in claim 1, further including: an end connector insertable through a second peripheral opening of either of said frames and which likewise has a sealing face for co-operating with a sealing face of said unit in said frame, said end connector having a threaded tubular portion for connection to a fluid conduit.
