ROLAND MORRILL, OF BENTON HARBOR, MICHIGAN.
SPECIFICATION forming part of Letters Patent No. 691,651, dated January 21, 1902.. Application tiled Tune 14, 1901. Serial No. 64,571. (No model.)
To a/ZZ whom t may concern.-
Be itknown thatI, ROLANDMORRILL, a citizen of the United States, residing at Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Sprayers, of which the following is a specification.
The present invention relates to sprayers of the class used for spraying plants, shrubs, trees, and other vegetation with insecticidal solutions.
More particularly stated, it relatesto what may be called an extension nozzle for sprayers intended for spraying high bushes, vines, trees, duc. r In sprayers of the class described it is desirable to conine the spray to a comparatively small local area, or at any rate it is frequently desirable to do so, and
these small local areas may be far above or In tree It may be desirable to spray a single infested bough or a portion of a bough, and this may be so far above or beyond the reach of the operator that either the pressure of' the apparatus is insufficient to carry the spray to it through the atmosphere, or elseif the pressure is sufficient the spray will be diffused over an unnecessarily large area-an area larger than that actually infested.. In such cases it is desirable to have a nozzle which has sufficient lateral strength to sustain its own weight and which is of sufficient lengthto enable the operator to place its discharge end in close prox-` imity to the part 'of the tree or vine or bush to be sprayed. These extension-nozzles are sometimes ten or twelve feet in length.
The object of this invention is to provide an extension-nozzle of improved constructionimproved to the end that it shall be light, strong, and durable. To these ends I construct the nozzle of two ttings-an inner tube for the solution, connecting them, and an outer jacketor sheathing so connected to the fittings that it cannot turn relatively to them or to the inner tube.
To these ends the invention consists in the features of novelty that are herein described.
In the accompanying drawings, which are made a part of this specication, Figure l is a side elevation of a stop-cock and nozzle embodying my invention. Fig. 2 is a longitudinal section thereof on a larger scale, an intermediate portion of the nozzle'being broken away.
A represents a casting which at one and the same time serves as the casing of the stopcock and the fitting for the base of .the extension-nozzle. This casting has the general outline of a cross, comprising a longitudinal branch a a and a transverse branch 0.2 a3. The longitudinal branch has a bore through it from end to end. At one end a ot' the longitudinal branch it has a cup-shaped enlargement adapted to receive the connection from the source of supply, while at the other end it has the features, hereinafter described, adapted to receive the other parts going to make up the extension-nozzle. The transverse branch has a tapering bore adapted to receive a correspondingly-tapering plug B, having a single transverse .part b, so that in one of its positions it obstructs while in another position, ninety degrees removed from the first, it leaves open the longitudinal b ore. At one end the plug has a thumb-wing.B,
and at the other end it has a reduced threaded portion Z9', adapted lto receive a nut C, which bears againstthe end of the transverse branch 0.3 and holds the plug firmly seated in its tapering socket. It is found in practice that the grit in thesolutions used soon causes leakage at the joint between the plug and the end a3 of the transverse branch of the casing, and in order to prevent this I provide the said end a3 of the transverse branch of the casingwith an external thread adapted to be engaged by correspondinginternalthreads on a cap I), which at its outer end is made non-circular for the reception of awrench by which it may be putin or removed from place. This cap completely covers the smaller end of the plug and prevents leakage of the solution onto the outside of the casing however loose the joint may be. g
The branch a' of the casting forms one of the fittings of the so-called extensionnozzle, the other of said iittin gs being shown at E. The branch of terminates in a tapering nipple d", surrounded by an annular flange a", which flares internally, so that between the nipple and ange there is left an IOO annular chamber, which in a longitudinal sec- I tion of the casting appears to be of truncated l V shape.
G is a light metal tube, one end of which is inserted in the bore of the branch aof the l casting A and permanently secured therein by solder or other suitable means, and the other end of which is passed through the bore of the fitting F and similarly secured.
H is a hollow non-metallicsheathing which 5 forms apart of the extension-nozzle and gives i it the necessary rigidity, while not making it i objectionably heavy.
I am not the first to construct an extensionnozzle of an inner tube, such as G, and an outer sheathing, such as H; but I believe that I am the first to so associate these parts that the tube and sheathing are incapable of movement (and especially rotary movement) relatively to each other. As heretofore arranged and connected they have been capable of rotary movement independently of each other, so that in the process of screwing the rose or equivalent tip onto or off of the fitting E the inner tube G has been subjected to a torsional strain which was in no way resisted by the outer sheathing, because of the comparative independence of the two, at least so far as twisting or torsional strains were concerned. As a result of this independence it has been a common occurrence to split or break in two the inner tube G by the simple act of applying or removing a rose or tip. In order to avoid this, I permanently and rigidly attach the outer sheathing H to the two fittings at the opposite ends of the inner tube G, so that the several parts make a composite whole and so that neither the tube nor the sheathing can twist without the other twisting correspondingly. To this end I preferably use for an outer sheathing a continuous piece of bamboo, the joints g of which are preferably bored the exact diameter of the tube G, so thattheyformbracesforsupportingsaid tube. y The larger end of this piece of bamboo, which is to join the casting A, is dressed off, so that it exactly fits the truncated V-groove of the fitting A. The other end of this bamboo pole fits in an annular socket formed in the fitting E as the result of a tapering nipplef and a ferrule F surrounding it and soldered or otherwise secured to the cast portion of the fitting. Having driven the reamed-out end of the elastic non-metallic sheathing H into the truncated V-shaped groove between the nipple ct" and the flaring flange the outer margin of a collar or extension-flange I, of ductile metal, (previously secured to the flange a" by solder or other suitable means,`) is turned or crimped inward against and closely in contact with the sheathing H, so that the latter cannot twist or turn about its axis relatively to the branch a' or the tube Gr in response to torsional strains put upon it.
As before stated, the part A is a casting,
and not being ductile its flange a cannot be turned or spun inward to engage the sheathing H, and this is the reason for making the extension of this ange of a separate piece of ductile metal, preferably sheet-brass, which can be soldered or otherwise permanently secured to the flange tt" and may be spun or crimped or otherwise deflected inward so as to engage and take a firm hold upon the sheathing H. In similar manner the fitting E is permanently secured to the sheathing I-I, so that the two are incapable of movement relatively to each other, especially about their longitudinal axis. Preferably the main part of the fitting E is a casting and the collar or ferrule F is of ductile material, the two being secured together by solder` or other suitable means after the ferrule is attached to the sheathing, which may be done by any suitable means, but preferably by spurs f', produced by a prick-punch.
