Ej ABLE PORTABLE SPRAYING APPARATUS May ]5, 1951 Filed Aug. 25, 1948 Patented May 15, 1951 OFFICE PORTABLE SPRAYING APPARATUS Eric Able, Birmingham, England Application August 25, 1948, Serial No. 46,025 In Great Britain August 29, 1947 Claims. 1

This invention relates to new or improved portable spraying apparatus and has for one of its objects to provide a simple and efficient sprayer which is economical to manufacture and easy and safe to use, and which has a wide range of practical applications.

According to my invention portable spraying apparatus comprises a receiver for air under pressure adapted to be held in the hand and to be connected by a flexible pipe to a tire pump or like means for compressing air, a small container for the liquid to be sprayed, a tube extending into the liquid and terminating in a nozzle or jet, and a head detachably secured to the receiver and having formed in it a passage which, at an intermediate point in its length, is in communication with the receiver, one end of the passage being open to atmosphere and the other terminating in a nozzle or jet adjacent to and having its axis substantially at right angles to that of the first nozzle.

Preferably the liquid container is mounted within the receiver and the tube and nozzle for the liquid are carried by a closure for the container which is mounted on or forms part of the detachable head.

To use the apparatus a quantity of the liquid to be sprayed is placed in the container and the head is fitted and secured in position. The pump is then operated and forces air under pressure into the receiver.

The air can escape freely from the open end of the passage in the head but when the users finger or thumb is placed against the end of the passage the air is forced out of the nozzle and the air stream as it is directed across the liquid nozzle picks up liquid and sprays it continuously in a finely divided or atomized form.

The spraying of the liquid is thus controlled solely by the application of a finger or thumb to the open end of the passage in the head and can be stopped or started instantly even if the pump is being continuously operated. Preferably the open end of the passage in the head is in such a position that the thumb can be applied naturally to it while the container is held by the fingers and the palm of the hand.

This arrangement has the further advantage that it is impossible for the receiver to be put under excessive pressure so that there is no risk of the receiver exploding.

One practical embodiment of my invention is illustrated by way of example in the accompanying drawings in which:

Figure 1 is a rear elevation of the apparatus.

Figure 2 is a side elevation.

Figure 3 is a plan.

Figure 4 is a vertical section through the upper part of the apparatus.

In the apparatus illustrated a is the air receiver or reservoir which is a cylinder or length of steel or other tubing closed at its lower end by a flanged closure 2) having at one side a connection for a flexible pipe 0. This pipe may have at'its outer end a nipple d to fit into the ordinary delivery connection of a foot-pump for pneumatic tires, or it may have any other form of terminal for connection to a convenient source of air under pressure.

The upper end of the cylinder a is closed by a flanged closure member e, the members e and b being soldered, brazed, or otherwise secured in an airtight manner to the cylinder.

The liquid container is a smaller cylinder f closed at its lower end and projecting at its upper end for a short distance through an opening in the top closure e in which it is soldered, brazed or otherwise secured in an airtight manner, The container f is arranged adjacent to one side of the cylinder 11 as shown in the drawings. Projecting upwardly through the closure member e adjacent to the other side of the container is a cylindrical rod g terminating in a short screwed spigot part h. This rod is drilled upwardly from its lower end to meet a transverse drilling 9' located a short distance above the closure member e. Fitting over the projecting part of the rod g there is a head consisting of a horizontal member it having a boss Z on its underside near one end, the boss and the head being drilled vertically to fit over the rod.

Adjacent the other end the head carries on its underside a flanged cap m adapted to fit over and close the upper end of the liquid container f. This cap carries a depending tube n of suflicient length to reach nearly to the bottom of the container, the upper end of the tube being screwed into the lower end of a vertical nozzle or jet p which is itself screwed into the cap. I

The head It has a horizontal passage q drilled through it at the level of the transverse drilling j in the rod. One end of this passage is open to atmosphere and the other end has screwed into it a jet or nozzle r of which the axis is just above and at right angles to that of the liquid nozzle 1).

Thehead la is retained in position by a wingnut s screwed on to the upper end of the rod 9 above it, compressible washers 15 being fitted over the rod between the top closure e of the air receiver and the boss I and between the wing-nut and the head. A compressible washer u is also provided in the cap m to seat against the upper end of the liquid container. A vent hole 12 is provided in the cap m to allow air to enter the liquid container to replace the liquid as it is used up.

By unscrewing the wing-nut s the head can be simply lifted off for filling or for emptying and cleaning out the liquid container, and the liquid feed tube n and the nozzles are then readily accessible for cleaning.

The two nozzles may be fitted with lock-nuts w so that each can be adjusted in an axial direction relative to the other.

When air under pressure is fed into the receiver a, it passes up through the drilled lower end of the rod 9 into the horizontal passage q and escapes to atmosphere from the open end of the passage.

To spray liquid the operators finger or thumb is placed against the open end of the passage and the air is then forced out of the nozzle -r to pick up liquid from the container 1 through the nozzle p and spray the liquid in a finely atomized form. The receiver a is of suificient capacity to eliminate or smooth out pulsations of pressure if the air is supplied to the receiver by a tire pump so that a steady pressure is maintained at the nozzle 1.

My improved apparatus can be used for spraying any liquid which can be picked up in any air stream from a nozzle. For example it can be used for spraying paint or liquid polish, for spraying insecticides, or for spraying fertilizing hormones in horticulture or agriculture.
