STEPHEN 0. PRICE, OF LOUISIANA, MISSOURL AND EARL E. RICHARDSON, 0F QUINCY, ILLINOIS, ASSIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, TO P. R. B. PUMP 00., OF HANNIBAL MISSOURI, "A. CORPORATION" OF MISSOURI.

' OIL DISPENSING AND MEASURING DEVICE.

United States, and residents of Louisiana,

Missouri, and Quincy, Illinois, have invented certain new and useful Improvements in Oil Dispensingand Measurlng Devices, of

which the following is a specification containing a full, clear,'and exact description, reference being had to the accompanying drawings, forming a part thereof.

This mvention relates to a dispensing device, and has for its primary object a measuring device, "which can be attached to the original package and the contents of the package be expelled by air pressure.

A further object is to'provide the original package of an oil containingdevice-wlth a' safety valve, a pressure'gage. and a measuring device so that predetermined amounts of the contents may be dispensed. In the drawings:

Figure 1 isa view of our device with all parts attached and portions in section.

Fig. 2 is an enlarged view of the pressure gage, safety valve and air valve.

Fig. 3 is an enlarged view of the method employed in connecting the dispensing mechanism to the tank.

Fig. 4 is a sectional view of the attachment made use of when it is desired to drain the tank without measuring the contents.

The construction of our device is as follows:

We employ a tank 5, which is of ordinary lene, lubricating oil, or in fact any other liquid. This tank or container isprovided.

with openings 6 and 7, and in the opening 6 is secured a nut 8, this nut being provided with internal and external threads, the internal thread portion receiving a nipple 9 and to this nipple is attached a cross 10, secured to the cross are the safety valve 11,- the pressure gage 12 and the air valve 13, in the opening 7 is secured the screw threaded plug 14 which is likewise provided with a threaded opening,- see Fig. 3, and through this opening is threaded the pipel5, this pipe extending practically to the bottom 17 I of the container or drum 5.

The projecting end 18 of the pipe 15 is provided with a swivel coupling 19, which is secured to a ipe or goose neck 20, this Specification of Letters Patent.

Application filed July 28, 1919. Serial No. 813,899.

. pipe being provided with the ordinary valve 21' and a swivel coupling 22. Secured to the swivel coupling 22 is a nipple which in turn is secured to a valve 2a,

which is secured to a measuring chamber This measuring chamber has a transparent cylindrical portion 26 and a measuring gage 27, the object of which is to indicate the amount .of fluid withdrawn from the measuring chamber. The bottom of this measuring chamber is tapered, as indicated by the numeral 28 so as to allow a free dis charge of its entire contents, and a valve 29 is secured to the bottom of this chamber so that the contents can be withdrawn therefrom.

The gage 27 is-graduated so that any predetermined amount of liquid may be withdrawn. The valvecasing 13 is provided with aspringactuated valve 30 which is of the mushroom type, the object of this being to allow air to be pumped into the container 5 but not allow it to escape from the container.

This air will lodge on the top of the liquid in the container and force the contents out through the pipe 15, the safety valve 11 acting to prevent excess pressure from forming in the container due to expansion of the liquid contained therein, and the gage recording the amount of pressure in the tank above the liquid, as it is a well known fact that liquid cannot be com- ,pressed, thus only the air above the liquid j will be compressed in the event of any exconstruction, and which may conta1n gasopipe may be attached when it is desired to drain the tank of its contents, or when the tank is used for spraying purposes, such as for orchards, flowers or other agricultural purposes.

In the upper end .of the measuring compartment 25 we place an air vent 32.. This vent is opened while filling the measuring compartment or drawing off its contents, so that no vacuum or compression will be formed during either operation. This vent is mechanically controlled by the float valve 33.

The operation of our device is as follows: It being a well known fact that the drums ployed.

When our device is used for dispensing lubricating oil, fuel oil, orin fact any other liquid which is dispensed by the quart, gallon, etc., the measuring device is attached and an accurate amount can be withdrawn without the use ofmeasuring pumps, but when it it desired to use this device for spraying or draining the entire tank, the measuring device is detached and the nozzle shown in Fig. 4 is substituted, and then a suitable hose connection attached to the nozzle. The valve 21 only serves the purpose of closing the pipe or goose neck 20 so that the contents of the container 5 will not be lost when the measuring device is removed therefrom, as the valve 24- will be removed at the same time It will be readily seen from the drawings that if the valve 21 is not closed, and the measuring device removed, the contents of the container 5'would be lost as the air pressure would drive them upward and out through the pipe 15, there being no relief valve to release this air pressure, nor is any desired by us, as one of our ideas is to maintain pressure within the container 5 at all times, until its 'entire contents are withdrawn.

Our invention has been developed with the idea of using the ordinary container in which gasolene is delivered, as a tank from which thegasolene may be measured and dispensed. These containers are air-tight so that they will hold the compressed air which may be forced into them thus making it unnecessary to providein an oil dispensing and measuring apparatus supplemental tanks or reservoirs for containing air under pressure. These containers are usually of such size that they may be easily moved from place to place. It is therefore desirable to provide'means for adjusting the measuring device 25 with reference to the tank to suit the convenience of those who will use it, and this capability of adjustment is provided by the swivel coupling 19 uniting the goose neck with the delivery pipe 15. By means of this the measuring device maybe swung to one side or the other of the tank and close to the tank or more distant therefrom as circumstances may suggest. This adjustment of the measuring'device would under certain eeoeeo this connection not only permits the adjust-- ment of the measuring device just described, but also its removal and the substitution therefor of a connection like thatshown in Fig; 4. j

Having fully described our invention, What we claim is:

1. An oil dispensing and measuring device, comprising a single tank for storing the oil and air under pressure, and provided with screw-threaded openings, an internally and externally screw-threaded nut secured in each opening and providing air-tight connections for said openings except through'the nuts, a cross shaped fitting detachably mounted in one of said nuts, a pressure gage and safety valve carried by said fitting, an outwardly seating check valve for admitting and retaining air under pressure carried by said fitting, a discharge pipe located in said tank having its upper end screw seated in.

the other nut, a goose neck provided with a cut-off valve, a swivel connection between the goose neck and discharge pipe permitting the same to be swung and adjusted to different sides of the tank, a measuring chamber, aswivel connection between the measuring chamber and'goose neck, whereby the latter may be disconnected from the goose neck and-adjusted so as to bring the scale on the measuring chamber in desired position indizpendent of the adjustment of the goose nec r.

2. An oil dispensing and measuring device, comprising a tight tank, a connection whereby air under pressure may be delivered to and retained in the tank, a discharge pipe connected with the tank, leading from the inside thereof near its bottom to the outside, a goose neck, a measuring chamber provided with a reading scale carried by the goose neck, a swivel connection between the discharge pipe and the goose neck permitting the measuring chamber to be swung around the tank to a desiredposition, and a swivel connection between the measuring chamber and the goose neck whereby the former may be adjusted to bring the scale to the desired position independent of the adjustment of the goose neck.

In testimony whereof, we have signed our names to this'specification, in the presence of two subscribing witnesses.
