Abstract
Abstract The air filter, the air regulator and the air lubricator, one or more of which are used in compressed air lines, such as those driving power tools, each having its own housing which may be selectively connected to one or more of the other housings to provide either a vertical or horizontal arrangement with respect to the air line axis with or without the use of fitting connections. The filter includes the metallic head containing inlet and outlet ports, a plastic chamber or bowl and a foraminous device therein to remove entrained impurities from the air and a collector to separate water from the air stream. The regulator includes a metallic casting with a valve means of controlling air flow responding to the diaphragm. The lubricator includes the metallic head containing inlet and outlet ports, a plastic chamber or bowl defining a reservoir and means to discharge oil vapor into the outlet port at a prescribed rate. By selective fitting of the housings together, communication is established through the inlets and outlets already provided therein and means is provided for securing the selected filter, or regulator or lubricator together. The respective housings interlock and nest together in different relationships to fit into existing spaces or to save space. In the lubricator arrangement, the volume of the lubricator bowl, which may be plastic, metal or other suitable material, is used as oil reservoir and means is provided to inject a spray of oil into the air stream as it passes through the housing. When the individual respective filter and regulator or the filter lubricator and regulator housings are in intimate, combined pressure-tight relationship with the bowls for lubricator and filter, the entire assembly becomes a combined housing.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
354 words
In a selective combination of two or three of the following: a. An air filter element, an air pressure regulator element and an air lubricator element for use in compressed air lines; b. Each of said air filter element, air pressure regulator element and air lubricator element having a separate, independent base complete with inlet and outlet portS and a closed chamber, such as a glass or plastic bowl, with a passage therein from said inlet to said outlet ports respectively through said closed chamber through which air under pressure is moved to be filtered, lubricated or regulated as appropriate to the particular element and its respective function, and each of said bases having a three-dimensional configuration arranged so that said bases may be brought together in connected engaged relationship with said outlet port in closed communication with a respective inlet port in the other to which it is connected and with which it is mounted as a combination; c. At least two of said three bases being formed with an offset portion having said inlet port and said outlet ports therein in other than in a straight line and the exterior of said two bases being offset in two dimensions to fit and interlock with the third element to bring said respective inlet and outlet ports of said respective elements in communication, and said third element having the inlet and outlet ports in its base substantially opposed; and d. said one of said two bases with an offset portion being combinable with the base having inlet and outlet ports, and with or without the other base with the offset portion, whereby selectively as desired the lubricator, filter and pressure regulator may be combined into one combination with two or three together so that there is a complete passageway from the inlet of one base receiving air through a pressure line or the like and said air passing through that said element on to the next element combined and connected therewith and through that element to the outside or other conduit with or without the said third element which may be combined selectively therewith.
Claim 2
Dependent Claim
