UNITED STATES PATENT OFFICE. a,
ALBY B. MOIDOLE, DECEASED, LATE OF BUFFALO, NEW YORK, BY CLARA "B. IICDOLE ADMINISTRATOR, OF BUFFALO, NEW YORK.
PAINT-SPRAYING 'NOZZLE.
Application filed September 24, 1920. Serial No. 412,468.
To all whom it may concern:
Be it known that ALBY B. MCDOLE, deceased, late of Buffalo, in the county of Erie and State of New York, did invent 5 new and useful Improvements in Paint- Spraying Nozzles, and the following is hereby declared to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a 1 part of this specification, and to the reference characters marked thereon.
Heretofore air brushes have been employed to a considerable extent for painting and varnishing various surfaces. These brushes are objectionable however, because they produce fumes which are liable to overcome the operators, some States having passed lawsprohibiting their use unless ventilating fans are used to carry off the fumes.
The principal object of the present invention is the provision of a spray-nozzle which is free from the above objection and which shall deliver the paint in a spray of uniform density from center to periphery, rendering it unnecessary to repeatedly move the nozzle back and forth or up and down over the surface under treatment to produce uniform work, as is required with air brushes or nozzles which deliver a spray varying in density in different parts thereof.
Further objects of the invention are to produce a nozzle which is especially suitable for spraying comparatively thick paint, such as oil paint; which can be adjusted to regulate the size of the spray, and which can be readily and thoroughly cleaned.
In the accompanying drawings: Figure 1 is a side elevation of a spray-nozzle, em
bodying the invention. Figure 2 is a sectional elevation thereof. Figure 3 is a horizontal section on line 33, Fig. 2. Figure 4 is an enlarged side elevation of the spirallygrooved plug.
Similar characters of reference indicate corresponding parts throughout the several views.
The body of the spray-nozzle is tubular and preferably comprises two telescopic sections 10 and 11 detachably united by a screw threaded joint 12. The rear or lower tubesection 11 is provided in its rear end with a threaded socket 13 adapted to receive the screw stem of a hose, not shown, which is connected with a supply tank containing liquid paint under air pressure, a suitable tank for this'purpose being shown in Letters Patent of the United States No. 1,311,827, granted to said Alby B. McDole on July 29, 1919. I
As shown, the front portion of the rear tube-section is reduced to form a shoulder 14 against which the front tube-section abuts. The portion of thd front section which extends beyond the rear tube-section contains a stationary cylindrical plug 15 which closely fits the same and is provided in its surface with spiral paint channels 16 extending from end to end of the plug and arranged equidistant around itg. Satisfactory results have been obtained with four of such channels, as shown, but a different number may be employed, if desired. The plug 15 is' provided with an annular base flange 17 which is clamped between the reduced front end of the tube section 11 and an internal shoulder 18 ofv the front tube section 10, thereby holding the plug from rotation as well as longitudinal displacement in the nozzle. The spiral channels 16 extend through said base flange and communicate with the bore of the rear tube-section which is flared or enlarged adjacent to the plug for this purpose,,as shown at 19.
Projecting centrally from the front end of the plug 15 is a pin or needle 20 which is adapted to extend more or less into a discharge opening 21 formed centrally in the head 22 of a screw cap 23 adjustably mounted on the front tube-section 10. The latter has an external screw-thread 24- with which the said cap engages.
The pin 20 is considerably smaller in diameter than .the cap-opening 21, so as not to entirely obstruct it when the pin extends into or through this opening.
A nut 25 applied to the threaded front tube-section and abutting against the inner end of the adjustable cap serves to lock the latter in its various positions.
As shown in Fig. 2, the channeled plug 100 terminates short of the front end of the tube-section 10 to form a whirl-chamber 26 into which the plug-channels16 lead.
In the use of the spray nozzle, upon admitting liquid paint under pressure to the 105 same, it passes through the rear tube-section 11 and thence through the spiral plug-channels into the whirl-chamber 26 whence it escapes though the discharge opening 21 and is projected against the surface to be Kw time,
her or less dense than another. is that a very material saving in time and labor is efiected, particularly in large paintpainted in a fine conical spray or mist of practically uniform density from center to periphery. The spiral channels produce a opening it expands into a conical spray of considerable area.
When the cap is unscrewed far enough to wholly withdraw the pin 20 from the discharge opening, a spray of maximum spread is obtained, while upon, adjusting the cap so that the'pin extends into its opening to a greater or less extent, a spray of reduced diameter is produced.
With this improved nozzle a surface cannot only be evenly and uniformly painted, but this can be done in a comparativelyshort for the reason that the uniform density of the spray does away with the necessity of moving the nozzle back and forth over a given spot several times as is required'where one part of the spray is thin- The result ing contracts.
hould any of the passages of the nozzle become clogged, hey can be readily cleaned upon unscrewing the cap 23, disconnecting and having a the tube- sections 10, 11 and removing the channeled plug 15.
This improved nozzle is especially desirable for spraying oil paint, for the reason that the numerous channels of the plug 15 effectually divide and break up the paint into a fine spray without requiring an unusually high air pressure in the paint-tank.
The claim of the invention is: Y A paint-spraying nozzle, comprising a tublar body composed of telescopic front and rear sections, the front section having 'an internal shoulder spaced from the op-.
posing front end of the rear section, a plug arranged in the bore of said front section base flange clamped between said shoulder and the front end of said rear section, said plug and its base flange bein provided with alining spiral channels an the front end of said plug terminatin below the corresponding end of "said ront body-section to form a whirl chamber, a screw cap applied to said front section and having its head provided with a central discharge opening, and a pin projecting forwardly from said plug and arranged to enter said discharge opening.
