Application filed m 1,-1920. Serial No. 378,243.
I To all whom it may concern Be it known that I, WILLIAM A. PITT, of
the city 'of Montreal, Province of Quebec,
Dominion of Canada,-have invented certain new and useful Improvements in Sprayers; and I do hereby declare that the following is a fullyclear, and exact description thereo My invention relates particularly to sprayers for applying paint, varnish and the like by means of compressed air and has for its object to provide a construction having a minimum number of parts and which will enable the delivery of the liquid to becontrolledfrom a point atfa" greater distance from the discharge end than has heretofore been possible, thereby'enabling more or less inaccessible points to-be easily reached' A invention, reference must be had to the. ac-
. companying drawings in which similar reflarger scale and illustrating the atomizer in erence "characters indicate the same parts,
and whereinz I A v Figure 1 is aside elevation of a sprayer constructed according to my invention; F
Figure 2 'is a similar view drawn to a section; I
F igure 3 Isa sectional view of thefitting connecting one end of the commingler pipe to the pressure line and section'line;
Figure-dais a transversesectional view taken on'dine 4 4; Figure 2; and Figure 5 is a detail modification ofthe means for manually actuati g the valve controlling thedischarge'outle of the sprayer. The embodiment of my invention 'illus} trated'in t he accompanying drawing consists of a commingler pipe comprisinga comparatively long section 2, a short section 3 and a flexible section 4 effecting a connection therebetween; The commingler pipe may be of any desired length having an atomizer upon the discharge end thereof. The atomizer is ofiset relatively to the pipe and comprises a casting in the form of an elbow 5 -oneend of which is screw threaded as at 6 for attachment to the commingler pipe while the opposite end terminates in a T' pointed out constituting a valve-case 7. The valve-case is disposed parallel to the .commingler pipe and its discharge end is closed "by. a cap 34 screwed thereon. This cap contains an opening 8 constituting a (valve seat for a needle-valve 9 the valve stem 10 of which extends axially through a stufiing-box 12 closing the opposite end of the valve-case, the free end of the valve stem being connected to the adjacent end of a push rod 13,
constituting an axial extension of the valve M stem and extending parallel" to commingler pipe 2. This push rod is of any desired length according to the length of sprayer re quired and it is slidably mounted in guide brackets 15 mountedupon the commingler pipe and held in position thereon by set screws 16. A helical spring 17 encircling the push rod and bearing between the bracket nearest the atomizer and a collar 18 upon the push rod, resiliently maintains the needle valve upon its seat. Any'means may be provided for opening and closing the valve. In the embodiment illustrated, this means consists of a nut 19 mounted upon the free end of they push rod which is screwthreaded as at 20. The nut is constructed I and arranged to bear against the adjacent guide bracket 15 and when rotated, tocause the push rod to feed axially therethrou h. An. enlargement 2 1 prevents complete is- .placement of the nut from the push rod.
To obtain a quick opening of the atomizer the-operator may exert an axial pull upon the push rod, the only'means resisting such a' pullbeing the spring 17 To maintain the push rod infull open position the latter'is provided with a lateral rib 22 which is adapted to normally register in ia notch 23 in the adjacent bearing bracket. When the push rod is in full open position ,the rib willbe located in rear ofthe bearing bracket and by a slight turn may be moved out of alignmenawith its notch 23 and conse-.' quently w11l actasa lock preventing the push rod returning to its initial position. The push rod is released from this position by turning it until the rib re'gisters with the notch at 'which point it will be automatically returned to the closed position under the in 'fluence of spring 17 It 'is to be distinctlyunderstood that this i is but one embodiment of my invention and i any means may be providedfor maintaining valve in full open the push-rod with the position. M
The end ofthe commingler pipe opposite to that connected to the atomizer is connected to the air pipe line 25 and to the suction line 26 leading from the tank (not shown) containing the paint, varnish or the like,
' air thereinto.
The nozzle is' screw-threaded as at 31 to enable it to be adjusted relatively to the .discharge opening 32 of the suction connection in order -thatthe suction Within the pipe may be increased or decreased as desired.
' It will,be seen that the arrangem'ent of the atomizer is such that the valve maybe 0 rated at a-considerable distance from the discharge end and consequently the operator is enabledto reachpoints which heretofore have been almost inaccessible with the spray-l are now in use, asfor instance in the painting of buildings and the like. Furthermore as the paint is commingled with the air .or
pressure medium at'a considerable distance from the atomizer a more perfect atomization is obtained than would be possible if p the air and suction lines were connected directly .to the atomizer.
