ATOMIZER FOR PAINT OR THE LIKE.
I Specification of Letters Patent.
Patented .Aug. 3, 1909.
- Application filed January 28, 1908. Serial No. 413,033.
ing of the said two valves has been eifected when the valve lever was moved, one after another without any noticeable interval,
- which was an objectionable feature in as far as it is of great importance to insure reliable working of atomizing apparatus that the compressed air should be first allowed sufficient time to act in order that the liquid paint may be properly atomized before the beginning of the work and its escape from the nozzle outlet. If, as was the case in hitherto known apparatus, the opening of thetwo valves is effected one after another without any interval, the person using the apparatus cannot determine at What moment the nozzle opening wasuncovered, so that it frequently happens that at the beginning of the Work, the liquid paint escapes in an insufiiciently atomized condition and thus neat working is not insured.
According to this invention, the handlever first depresses'the free end of a onearmed lever resting against the compressed air valve spindle and thus opens the compressed air valve, until the hand lever strikes a fixed-stop, and, by pivoting about it, opens the nozzle I The compressed air valve is thus opened by pressure, and the nozzle valve by traction, and the resistance offered before the nozzle valve is opened, is so great that the operator is able first to let the compressed air act for a sufliciently long time before he starts the apparatus by opening the nozzle valve. In this way he is able to work in a very neat manner.
A constructional form of apparatus according to this invention is illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the apparatus, partly in section showing the valves closed. Fig. 2 is asimilar view, broken ofi,

with the compressed air valve opened. Fig. 3 is a corresponding view with the two valves in open position, while Fig. 4 is a section on. lines AB of 1. The apparatus casing a carries in the usual manner the tank 1) receiving the liquid to be atomized. The valve spindle (1 passes through the nozzle c and closes the nozzle valve in the manner shown in Fig. 1. The end ofthe valve spindle at opposite the nozzle, adjoins a sleeve e inclosing'a helical spring f. The free end of the said sleeve 2 is guided by a pin 1 of a pipe or rod Z? pivoted about a piir Z, the said pipe Z forming, with a bar I the I apparatus frame. After disconnecting a nut Z the pipe Z can be moved into the dotted position shown in Fig. 1, whereupon the different parts'pf the apparatus can be easily taken to pieces.
About a screw-threaded in gof the pipe c is pivoted the two-armed and lever h, the free end.h"of.which rests against a projection 'i of a one-armed lever i pivoted about a pin .11 One end position of thelever h is im'ited by a fixed in k If the lever h is slightly raised, an -thus caused to swing about the pin g, its free end h will press against the one-armed lever'i, which, on
turning about thepin t presses the valve spindle k, at the same time overcoming the s ring Yr, in the manner shown in Fig. 2, so that the compressed air valve is first opened, and the compressed air admitted through the pipe m can enter the apparatus in the well nown manner. After the compressed air valve has been opened, one arm of the lever h comes.to rest against the fixed stop (Fig. 2). If the hand lever is moved stil farther upward in spite of the resistance which becomes noticeable, then the hand lever turns about the fixed stop p, and acts as a one-armed lever, the sleeve e being caused to participate in the movement, the
s ring f being overcome, and the valve spind e dis. brought into the position shown in Fig. 3. The two valves, namely the compressed air and the nozzle valve are then opened, in' which state the apparatus begins to work.
The hand lever k can be conveniently moved by first o ening only the compressed air valve and al owing the air to act for a sufficiently long time in order to make ,sure that, on opening'the nozzle valve, the liquid will leave the nozzle 0 ening in a properly atomized condition. The essential point is means constituting a fulcrum for said needle that the one-armed lever i presses against the I air valve spindle is, so that the said valve is opened under pressure, while the nozzle valve is brought into the 0 en position by traction. The operator fee s then exactly what is happening and always knows whether one or both valves is opened.
Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is 1. In an atomizer of the class described, a needle valve, an air valve, a hand lever pivoted to the needle valve, a one armed lever for said air valve extending to the opposite side of the needle valve and having a hooked extremity adapted to constitute a fulcrum for said hand lever, anda spring for impelling said needle valve into its closed position.
' 2. In an atomizer of the class described, a liquid valve and an air valve, separate operating levers therefor, a spring for impelling the needle valve into closing relation, a freely removable lever constituting an abutment for said spring, and means on said needle valve engaging said air valve lever at the inception of movement 'of the former, said valve lever, when said air valve is opened.
3. In an atomizer of the class described, a
needle valve, an air valve, a hand lever pivoted to the needle valve," and a onearmed lever for said air valve, extending on the opposite side of the needle valve and having its free extremity ada ted to constitute a fulcrum for said hand ever, and means for imelling said needle valve into its closed re-- ation.
4. In an atomizer of needle valve, a spring for impelling the same into closing relation, a freely removable abutment for said s ring, a hand le'ver pivoted to said needle va ve, an air valve, and means for operating said air valve. and adapted to have an abutting engagement with sald hand lever to constitute a fulcrum therefor after the air valve is opened, whereby said air valve is o ened before the needle valve and said need e valve is freely-removable by re moving said abutment.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
