AIK LINE OILER.

Application filed November 3, 1925. Serial No. 66,515.

This invention relates to oiling devices, but more particularly to devices which are attached to air lines for introducing oil into the air current utilized for operating fluid actuated machines. I s

It is an object of this invention to eliminate interruptions in drilling and similar operations for the purpose of oiling the working tool; Another desirable object is to introduce the oil into the air current in uniform quantities suitable for immediate needs.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention consists of the combinations of elements, features of construction andarrangement of parts having the general mode of operation substantially as hereinafter described and more particularly pointed out in the appended claims and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal view in elevation partly in section of an air line oiler, and

Figure 2 is a transverse sectional View in elevation taken on the line 22 of Figure 1 looking in the direction of the arrows.

Referring to the drawings, A indicates a casing having a partition or wall B which divides the interior of the casing A into an oil reservoir C and a passageway D. The

reservoirO is preferably arranged above the passageway D and the portions forming .the wall B are preferably inclined so that the oil E in the reservoir will be directed toward the center portion of said reservoir.

The casing A may be either rectangular or cylindrical in shape but'the base F, or that portion upon which the casing normally rests, is preferably of concave form so that the casing may be readily moved over irregular surfaces, such as mine floors for instance, without catching upon any irregularities.

, In order to enable the pressure fluid flowing through the passageway D to pass into the reservoir C above the level of the oil E and to enable such oil to be delivered into the main passage D, a passage G is formed through the wall 13 and is of sufficient diameter to receive loosely a plain imperforate cylindrical pin H. The pin H is preferably sufliciently smaller than the passage Gr so that a slight space J exists between the wall of said passage and the pin. The pin H rests on the wall or base F at one end and extends entirely through the reservoir C and the passageway D. a

Suitable means are provided for obtaining access to the reservoir C and for in serting the pin H into the passage G, and. to this end a screw threaded aperture K is formed in the top of the casing A to receive a correspondingly thread plug L. The plug L in this instance is provided with a recess 0 to receive loosely the upper end of the pin H and is adjustable to prevent undue endwise movementof the pin H.

The operation of the device is as follows :-Pressure fluid, such as compressed air, entering the passageway D from an air line P will, by the pulsations caused by the cut-oil and admission of pressure fluid in the tool to be oiled, cause the pin H to vibrate transversely of the passage G. At the same time a portion of pressure fluid will pass through the passage G above the surface of the oil E thus creating a pressure corresponding to the pressure in the passageway D and will therefore permit some of the oil to find its way into the space J. Asothe pin is forced against the wall of the passage G, a portion ofthe oil will be forced from therebetween into the passageway D where it will be received by the pressure fluid passing through said main passage and will be carried to the operating tool.

I claim:

1. An air line oiler comprising a casing, a

wall dividing the easing into a pressure fluid passageway and an oil reservoir, said wall having a single passage for conveying pres sure fluid from the passageway into the reservoir and oil from the reservoir into the passageway, and a plain cylindrical pin extending through the passage and the top of 9 way into the reservoir and oil from the re ervoir into the passageway, and a plain cylindrical pin in the passage supported at one llO end by the bottom wall of the passageway and extending with its other end loosely into the recess, said pin being actuated transversely of the passage by the pulsations occurring in the pressure fluid for forcing oil from the walls of the passage into the passageway, said pin extending entirely throu 'h the reservoir and the passageway.

3. an air line oiler comprising a casing having a threaded aperture in its top, a wall dividing the easing into a passageway for pressure fluid and a reservoir for oil, said wall having a single passage of uniform diameter throughout its length for conveying 15 pressure fluid from the passageway into the reservoir and oil from the reservoir into the passageway, a cyhndrlcal lmperforate pin 1n the passage extending entlrely through the passageway and the reservoir and supported at one end by the bottom wall of the passageway, 831d pin being actuated transversely of the passage by the pulsations ocspecification.
