(Cl. 184-55") My present invention, in its broad aspect, has referenceto improvements in lubricating and cleaning device for Monotype keyboards. My de water, and sediment fromv the oil container; It will‘ be noted‘ that the bottom is slightly convex. The ?ller tube.

As shown by the dot-and. My device“ is; also a cleaner, since it removes dust dash line in Figure 1, the level of oil‘ in the con~ and the like, and; in itsaction, the tendency is IO tainer is close to. the top of the tube. A tubular to remove all’ moisture from the air. There are connection I3 to an air line (preferably the air over seventy-?ve valves and pistons and other line of the Monotype machine) is on the oppo working parts in a Monotype keyboard, which site side of the container, and has a branch I4 must be completely or partially dismantled to leading into the container slightly above its mid complete a cleaning and oiling Operation. My 15 dle point for atomizing purposes (as will herein invention attains both ends without dismantling after be described), and a slightly larger branch and in addition, moisture is removed from the air. My device is designed to be hooked up with the Monotype air line and removes all dirt, dust and the like, which ordinarily passes through the air line. My device is simple, sturdy and prac tical, and is applicable to all conventional Mono I5 leading into the container near the top. The branch I4 extends into the container and has an angled end I6, while the branch I5 merely extends through the Wall of the container. A valve I1 is located in the air line connection be tween the branches I4 and I5, so that air may type machines. be introduced into the container ‘for oil atomiz Other and equally important objects and ad ing purposes, or the air may be directed through vantages of my invention will be apparent from 25 the upper branch I5 and discharged directly the following description and drawings, but it is through the outlet conduit I8 on the cover, which pointed out that changes in form, size, shape, materials, and construction and arrangement of parts is permissible and within the purview of my broad inventive concept and the scope of the appended claims. In the drawings, wherein I have illustrated a has a threaded end I9 for use of a ?exible con container of my device, which is preferably the most suitable place by connecting the airline to the connection I3. My device does not change the air pressure but merely mixes oil with the nection, or nozzle, or other attachment, if de sired. The oil atomizing tube 20 is a small tube ex tending at an angle down into the body of oil and having an angularly cut end 2| opposed to preferred form of my invention: , the end I6 of the branch [4.

On the end of the Figure 2 is a section on the line 2—2 of Figure 1; atomizing tube 20 is a cylindrical, screen paneled Figure 3 is a section on the line 3-'—3 of Figure 1; strainer 24. The construction of the strainer 24 Figure 4 is a top plan view, and incloses a cylindrical body 25 with a top‘ and Figure 5 is a vertical section. bottom and spaced elongated screened openings In the drawings, wherein like characters of 26.

My The numeral I designates the cylindrical oil device is inserted in the incoming air line at formed of a thin sheet metal 2 and has a bottom 3 and an open top closed. by a cover 4. The top has an annular edge ?ange 5 beneath which is air as it passes through the device. This air an annular reinforcing ring 6—see Figure 2 and above which is an annular sealing gasket ‘I. then goes into the keyboard and operates the valves and pistons therein by means of the out The cover 4 ?ts down on the gasket and screws let I8, as the compressed air goes through my device a certain amount of oil is atomized and mixed with the air and as the air passes through the different parts of the keyboard they are lu— 8 in spaced relationship about the edge of the cover-see Figure 4-—pass through the cover, gas~ ket, ?ange and reinforcing ring to hold the cover on the container in. non-leakable assembly. The bottom has a drain cock 9 for removing dirt, 55 bricated by the oil particles. , Valve I1 is to stop the device from operation 2,406,651 3 . if desired without the necessity of removing it from the air line such action be caused by the fact that branch l5 being larger than branch Id. The air would bypass branch l4 and follow the line of least resistance through branch l5, thus oil would not be mixed with the air passing 4 keyboards, comprising a container for oil, a ?ller and oil level measuring tube at the side of the container, an air intake conduit at the other side of the container, spaced branches from the con duit into the container, a valve in the conduit between the branches, 2. screened atomizing tube in the oil of the container and associated with one of the branches, a cover on the container, Any supply of air under pressure may be used and an outlet conduit on the cover. for connection l3 but it is easier to use the air 2.
