A petcock |69 is` 55 This is a divisional application divided from co-pending application, Serial No. 61,982, led February l, 1936.

Our invention relates, in general, to dispensing .I devices and more particularly to devices for pumping lubricating oils and greases out of their original container, and conducting the oil and grease directly from the original container to the parts to be lubricated, and also for holding Figure 2, shows the device illustrated -in Figure 1 with the compartment in raised position;

Figure 3 represents a form of our device in which the cover and pump is raised by compressed air or other iiuid under pressure, the 5 compartment remaining in lowered position; and

Figure 4 showsl a partial view of the form of device shown in Figures 1 and 2, but with a different means provided for introducing the commounted on the exhaust pipe 68 so that when the petcock is turned in one direction, the exhaust pipe |68 is closed and when turned in another direction, the exhaust pipe |68 is opened.

In operation, in order to raise the compartment I3 and to insert or withdraw the container 8| from under the compartment, air from a source of compressed air is inserted through the valve I 1|. When the compartment is to be raised, thepetcock |69 is placed in a closed position so that the air will not escape through the exhaust pipe |68. This compressed air introduced into the tops of the cylinders |65 causes relative movement between the walls of the cylinders |65 andl cylinders |65, which gives a smooth and gradualoperation.

In order to prevent the wobbling of the piston stem within the walls of the cylinders |65, especially when in a raised position, we provide the guide washers |62, which being mounted part way down from the piston |64, act as a brace. Secured in the bottom of the cylinders |65 are the washer blocks |13 which act to cushion the striking of the guide washers |62-upon the bottom of the cylinder wall. The guide -Washers |62, in engaging the blocks |13, prevent the cylinders |65 from rising beyond the position permitted by reason of the guide washers |62 engaging with the blocks |13.

In Figure 2, the same device as was shown in Figure 1 is illustrated, but shows the compartment in a raised position. When in this position, the inlet member 49 and end 50 of the pump I6 are raised up out of the opening 82 in the container 8| which sets below the raised' compartment. In this manner the original container" 8| may be moved sidewards on and olf the base II. As is illustrated, the action of the compressed air has raised the cylinders |65 and caused the block washers |13 inserted in the bottom of the cylinders |65 to engage the guide washer |62.

When it is desired to lower the compartment again, it is necessary to permit the compressed air in the upper. portion of the cylinders |65 to escape through the exhaust pipe |68 and the petcock |69 by turning the petcock |69, thus exhausting the compressed air and permitting the cylinders |65 to be lowered. After the exhaustion of the compressed air, the device again assumes the position shown in Figure 1. In Figure 1l and Figure 2, the compartment and the cover are permanently joined together.

In Figure 3, we show a modied form of the utilizing of compressed air for the raising of the inlet member out of the original container. In this form, the cover I5 rises up oi the top of the compartment I3 and the sides of the compartment |3 are securely fastened to the base and a door I4 is provided on one side of the compartment I3 permitting the insertion and withdrawal of the original container" through the side of the compartment I3. In this form shown in Figure 3, the compartment I3 remains secured to the base II, but the cover I5 is raised by means of compressed air. In order to provide a brace for the top of the cylinder to engage the cover, we provide angle members |14 which `are suitably engaged by bolts or welding to the top of the cover I5. The upper portion of each o1' the cylinders |65 is provided with a shoulder |15 adapted to engage respectively the lower surface of the angle members 14. The shoulders |15 are welded or otherwise secured to the angle members |14. In this way, the cylinders 65 are rigidly secured to the cover I5. In other particulars, the construction is similar to that shown in Figures 1 and 2. It is readily seen that the operation is the same, except that the action of the compressed air upon the cylinders and the pistons causes the cylinders to rise, which lifts only the cover I5 and the pump and inlet member instead of raising the whole compartment.

In Figure 4, we illustrate a modification of the device shown in Figures 1 and 2. In this modification instead of manually applying a hose leading from a supply of compressed air to the pipe leading to the cylinders, the air supply to the pump is utilized. As shown in Figure 4, a pipe |19 leads from a source of compressed air and is directed to the multiple Valve through the L-shaped opening |18 in the valve |80. By turning the handle |11, the L-shaped opening in the valve |80 is positioned so that the open ends of the L-shaped opening Will communicate with any two of the adjoining pipes, the pipe |19, the pipe |16 to the pump, the exhaust pipe |8I, and the pipe |10 to the cylinders. When the lifting mechanism is to be operated and air' is to be introduced into the cylinders 65, then the valve |80 is adjusted so that the compressed air from the pipe |19 is conducted through the valve |80 and into the pipe |10 to the cylinders |85. After the compartment has been raised, and it is desired to exhaust the air in the cylinders |65, the valve |80 is adjusted so that the compressed air in the cylinders |65 is let out through the pipe |18 through the valve |80 and out through the exhaust pipe |8I. In this way, the turning of the handle |11 of the valve |80 will operate either the pump, o r the lifting mechanism so as to raise or lower the compartment I3.

It can be seen that the use of compressed air or other Icompressible fluid may be utilized for easy raising and lowering of the inlet member 49 in and out of the original container 8| and providing' an easy and simple manner of changing its position relative to the compartment I3. When the modication shown in Figures 1 and 2 is used, the original container 8| is moved sidewards under the compartment when raised. When the modification shown in Figure 3 is used, the original container" 8| is put through the side of the compartment I3 by opening the door I4 and by raising the inlet member 49 upward so as not to hinder the sideward move of the original container 8|.

The illustrations shown are especially adapted for use in dispensing grease, oil, or other lubricant capable of being pumped or forced through a conduit. However, it isl to be understood that this device may be used for dispensing any fluid capable of being pumped or forced through a conduit regardless of itsviscosity.

The great advantage resulting from the use of our invention is apparent from an inspection of this device. For examp1e,-when our device is used in dispensing grease for lubricating automobiles, the grease need not be taken out of the original container and placed in another container, as would ordinarily be done. By using our device, the grease may be transmitted directly Although we have described our invention with l a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
