l. J. 'AMATO S PRAYER Filed July 11, 1934 2 Z T; Z A 5 Patented Oct. 27, 1936 SPRAYER Irving J. Amato, Pittsfield, Mass., assignor of onehalf to Edward F. Fahey, Pittsfield, Mass.

Application July 11,

' 1 Claim.

My invention consists in the combination of a sprayer which is constructed and operates without the use of a tube extending into a liquid receptacle.

The primary object of the invention is to provide a sprayer without the use of a tube extending into the liquid receptacle, and so constructed that all the liquid in the liquid receptacle may be used or sprayed by the simple method of changing the angle or inclination of the liquid receptacle when spraying, and to prevent any of the liquid from being drawn into the air pump.

Another object of the invention is to provide a sprayer with a ball valve located in a casing on the inside of the air pump, and the ball valve so constructed to operate alternately when a pressure of air is drawn in and forced out of the air pump, thus preventing any of the liquid entering the air pump and interfering with the action of the plunger. 7

My invention may be used for varied purposes, such as spraying disinfectants in the home or sick room, and also for spraying vines or plants, and also to prevent evaporation of the liquid within the liquid receptacle.

The invention also consists in certain other features of construction and in combination and arrangement of the several parts, to be hereinafter specifically described, illustrated in the accompanying drawing and set forth in the appended claim.

Referring to the drawing, in which like numerals of reference designate like parts in the several figures:

Figure 1 is a plan view.

Figure 2 is a side elevation view.

Figure 3'is a front elevation view.

Figure 4 is a central vertical section through Figure 3.

Figure 5 is a front view of the ball valve.

Figure 6 is a sectional view of the ball valve.

Figure '7 is a modified means of regulating the air within the plunger.

Figure 8 is a sectional view of Figure 7.

Referring to the drawing, I indicates a liquid receptacle which may be either a bottle or a metal container, and in shipment is provided with a screw cap or cover similar to the cap or cover 2 shown on the drawing. The numeral 2 indicates a cap or cover that screws onto the liquid receptacle I, and is provided with a gasket 3, on the inside, to prevent the liquid from leaking. A spray tube 4 extends through the cover ,2 a short distance beyond the gasket 3 and is fitted to the cover in an air-tight manner. By using a short 1934, Serial No. 734,669

tube that does not depend into the liquid receptacle, I am able with my device, to use all of the liquid without any waste which is the case in the ordinary sprayer.

that is sweated to the pump in-an air-tight manner, a ball valve I4 is sweated to the casing I3 also in an air-tight manner. This ball valve consists of the body I4 and is provided with the hole I? that runs therethrough. A ball I8 is inserted in the upper part of the body I4 and is fitted to the lower part of the hole H and said hole forms a seat for the ball I8. There is enough clearance in the upper part of the hole I'l so that the ball I8 is free to pass up and down when agitated. The top of the hole I! is slightly peened over, as indicated by the numeral I9, so that'the ball may not pass therethrough.

In Figures 7 and 8 I have shown a modified form of valve used with my device. This consists of the casing 23 which is inserted in the barrel of the air pump 8 in a similar manner as the casing I3, a disk valve 2| is fastened to the casing by means of the valve stem 22 which is inserted through the hole 23 in the casing 20 and peened over on the end, as indicated by the numeral 22, t hold it in positon. This valve operates in a similar manner as the ball valve I4.

The pump 8 is provided with an inner casing l3 My device operates in combination with an air pump comprising the pump 8 with a plunger I5 operated by means of the rod 9 and the handle Hi. The pump is provided with a cap 6, indented as indicated by the numeral 5, so that thetop of the spray tube 4 may be placed in close proximity to the air hole I2 in the cap 6. The air pump is securedly. fastened to the top of the cap or cover 2 by sweating or other means. The numeral II indicates the air inlet to the pump. The cap 6 is provided with an inner casing I3, forming an air chamber between the cap 6 and the inner cover I4 so as to prevent any liquid from being sucked into the pump.

The device is operated as follows: As the contents of the receptacle are being lowered, the operator tilts or inclines the receptacle causing the liquid to enter the spray tube 4. When the plunger I5 is drawn up the pump barrel 8, the ball I8 will be drawn into the seat formed by the hole ll thereby preventing any liquid that may have been deposited in the pump, between the cap 6 and the casing I3, and also any liquid being drawn from the spray tube I into the barrel of the pump 8. This is a very decided advantage as most of the plungers in the ordinary pumps get out of 7 order or do not work properly becauseof the effect through, a partition across said barrel spaced inwardly from said cap, and a check valve in said partition opening toward said cap, a container cover secured to said barrel, a spray tube extending from the interior of said cover and across the 5 outer face of said cap to a point adjacent said air outlet hole, and a liquid container removably secured to said cap.

IRVING J; AMATO.
