SPRAYING-NozzLE.

BPEGIFIGATIQN forming part of Letters Patent No. 604,873, dated May 31, 189B. Application filed February 4, 1895. Renewed January 28, 1893.: Serial No. 66v8,349. (No model.)

To all whom it may concern:

Beit known that we, JOHN BEAN, of Los Gatos, Santa Clara county, California, and ROSCOE BEAN, of Hudson, Lenawee county, -Michigam have invented certain new and useful Improvements in-Spraying-Nozzles; and' solid matter held in suspension thereinsu ch ,d for example, as water containing ari-excess of paris-green or other poison beyond the point of saturation or in powdered form-and designed for the spraying vof fruit-trees, &c., for the purpose of destroying the insects with which they may be affected.

The object of the invention is to provide an improved construction in devices of the char-l acter referred to and it consists inthe matters hereinafter` set forth, and particularly pointed out in the appended claims.-

In the accompanying drawings,Figure 1 is a general view of a spraying-nozzle embodying onr invention in' an elongated form suitable- .for 'spraying fruit-trees. Fig. 2 is a longitudinal sectionalV detail of the nozzle proper.

Fig. 3 is a similar view showing the end of the nozzle depressed fo'r the purpose of clean ing its spraying-orifice. Figs. 4 and 5 illustrate removable spray-plates -with diierent. sizes of spraying-orifices. Fig. 6is a fragmentary detail of the upper end 'of the inner-tube of the nozzle. Fig.`7 is a top planview of ,the nozzle with the top cap and spray-plate removed. Fig. Sis a. sectional view of the end of the nozzle, showing a lmodie'd form thereof. v

-, In said drawings, A designates the lower mainportion. or tube of the nozzle, and B -a cylindric cap placed over the lupper end of said tube and arranged tofhave a limited telescopic or longitudinal sliding movement' thereon. The interior` of the cap B when in its extended or uppermost position forms a ter by a minute orifice b, through which the liquid is discharged from the nozzle.

. A2 designates an upwardly-proj ectin g spur or point located centrally upon the upper end of the tube A directly opposite the spray-ori- 'ice b.- Said point is f r the purpose of clearing the discharge-ori ce b of the powdered substance carried by the water or other matter which may' have accumulated therein,

- land is brought into action by simply depressing or forcing down the cap B over the-tube.

yA until the clearing-point enters the discharge-orifice, as shown in Fig. 3.' This operation may be 'accomplished when the water'- supply is turned olf, but may obviously be equally well accomplished when it-is turned on, if so desired, it being only necessary in the latter case to 'apply sufficient additional force to the cap, either by forcing the nozzle lagainst a limb or projection or by means of a vstring or wire tied or fastened to the cap and of sufficient length to reach the operator, whereby the teleseoping cap may be drawn down over the tube by merely pulling on the string or wire, to overcome the Water-pressure within it, which pressure will obviously tend to maintain the cap in its outermost position. 'A The cap is prevented from being forcedfoff kthe tube by the Water-pressure by means of a suitable stop, consisting in this instance of a lug or pin a, projecting from the upper end of the tube A vwithin the cap and adapted to engage an upwardly-facing annular shoulder b' 'on the interior of the cap.

-When the water'is turned on, the cap is at,

once forced outwardly until said stop-pin and shoulder are brought into contact and willl be normally maintained iu'its outermost Aposition so long as the iow continues.

The passage A in the upper end of the tube A is arranged to vdischarge somewhat tangentially into the chamber C, so as to produce a'whirling or rotary movement in the liquid within the chamber, and asa further` IDO improvement is also arranged on an upward inclination, so as to give the jet issuing therefrom an upward as well as atangential direction. As herein shown, the passage consists of a lower portion a', which opens vertically upward from the interior of the tube A, at one side of the center thereof, and an upper spirally-shaped portion a2, opening laterally out of the lower portion a' and extending on an upward inclination to the exterior margin of the tube. Said upper portion a2 of the passage is, moreover, herein shown as located so close to the upper face of the end of the tube A as to be uncovered or in open communication with the chamber C throughout the greater part of its length and as widened at its outer extremity, so as to provide a perfectly free discharge from the passage. The eiect of the upward inclination ofthe tangential discharge-passage A' is to throw the liquid upward through the spray-orifice b with greater directness and force, thereby producing fuller and more powerful discharge from said orifice. The interior of the cap B is in this instance made somewhat larger in diameter in its upper portion or chamber C than the exterior diameter of the tube A, and the annular shoulder formed Where its diameter is reduced to fit said tube constitutes the stop-shoulder b', against which the stop-pin a' strikes in limiting the upward movement of the cap on the tube. At its lower end the cap is' shown as provided with a stuing-box B2, having screw-threaded connection with the body of the box and within which any suitable packing b2 may be compressed to prevent leakage between the cap and tube.

As a further improvement the spray-plate B' is herein shown as made separate from the rest of the cap, and consists of a circular plate or disk of somewhat larger diameter than the upper interior portion or chamber C of the capl and adapted to be securely held over the top of the chamber by means of a clampingsleeve B3. The latter comprises a cylindric portion b3, fitting over the plate B' and the upper end of the cap and having screw-threaded engagement with the latter, and provided at its upper edge with an inwardly-projecting annular flange b4, between which and the body of the cap the plate B is clamped. Interchangeable sprayplates having various sizes of discharge-orifice b may consequently be provided with each nozzle, and the form of the spray thus readily varied to atord a coarser or finer shower, as desired.

D designates a tubular extension or handle, upon the upper end of which the nozzle hereinbefore described is adapted to be Secured when it is desired to sprinkle fruit-trees or other vegetation that rises to a considerable height above theground. Said extension or handle comprises, as herein shown, a metallic inner tube or pipe D' of any desired length and a tubular outer covering D2, which may be conveniently formed of a bamboo pole with the pith removed, or may be of some other light and stiff construction, and within which the inner tube D' is inserted. Such outer covering D2 is in this instance secured upon the inner tube D between an annular shoulder d at the lower end of the tube and a coupling-sleeve D3,which is interiorly threaded to fit corresponding exterior screw-threads on the upper end of the tube and is screwed down over the latter, so as to clamp the outer covering between it and the lower shoulder d. The upper end of the sleeve D3 is exteriorly screw-threaded to t within an interiorlyscrew-threaded enlargement of the lower end of the tube A of the nozzle, and thus forms a coupling between the nozzle and handle.

The lower end of the tube D is adapted for connection with a ilexible hose E, leading from the liquid-reservoir or other source of water-supply, and any suitable globe or other valve or cock F may be inserted between the tube land hose for enabling the discharge through the nozzle to be regulated as desired.

In Fig. 8 we have shown a construction in the spraying-nozzle which embodies the principal features illustrated in the other figures of the drawings, but which has the advantage of being more simple in structure and more economical to make. In this instance G indicates the main portion or tube of the nozzle, which is identical in construction with the tube A of the other figures of the drawings, with the exception that in this case the stop-pin a is not secured in the tube G; but

.the latter is provided with a longitudinal slot g, which is engaged by a stop-pin h2 in the cap H and the outer end of which forms a stop for limiting the outward movement of the said cap. Said cap H consists of a tubular part or body which immediately engages and slides upon the tube G and is provided with an integral outer or end wall H', provided with a central spray-orifice h. At its lower end the cap is provided with a stuffingboX H2, formed by means of a ring or gland h', the lower part of which ts the tube G and the upper part of which is adapted to receive the lower end of the cap H and is provided With interior screw-threads engaging exterior screw-threads on the lower part of the said cap. The pin Wis inserted through the ring h' and projects into. the groove g, so as to limit the outward movement of the cap, and prevents the same from being detached from the tube. A central pin or projection g ou the end of the tube Gserves as a. clearing-point to keep open the discharge-orifice h in the same manner as hereinbefore described. The construction illustrated 'in Figs. 1 to 7 has the advantage of enabling the size of the spray-orifice to be changed by the insertion of plates B', having orifices of different size, this being a feature which is not present in the construction illustrated in Fig. 8. The device illustrated in Fig. 8, however, is obviously much less expensive to construct,

having only two parts and'one screw-joint. The arrangement of the limiting-stop in Fig. 8 is superior to that shown in Figs. 2 and 3; but such a stop-pin and groove may be used in the construction shown in Figs. 2 and 3' equally aswell as in the construction shown in Fig-8. -Y j Some advantages derived from the use of a sliding cap in connection with `the main tube of the spraying-nozzle may be obtained when theclearing point or projection on the main tube is omitted, it being obvious that when lthecap is forcibly pressed backward on the tube the-water within the chamber of the cap will be ejected with greatly-increased. force from the spray-orifice, so that a clearing of the` orificeinay be produced even though no clearing-point be present. The use of a clearing-point is advantageous, however, and the same yis hereinafter claimed in combination with other features of the inventiom As far as theproduction of a spray as distinguished from a solid jet or stream is concerned this result may be produced by thel employment fof --a chamberexterior to the closed end of the main tube of the nozzlel when the hole leading through the closed end of the tube is larger than the spray-orifice or is placed out of alinement with the same, and a .constructionembracing such chamber is therefore herein claimed as part of our invention without restriction to the sliding feature of the cap, Which'latter is employed solely for the purpose of facilitating the clearing of the spray-orifice.

Obviously the several features of improvement involved in' our invention as hereinbe-v fore described may be employed with advantage separately and in other connections than .those particularly referredto, although to gether contributing to superior results in the special .structure and for the purposes especially set forth.

We claim as o'ur-invention-A l. A spraying-nozzle. comprising a main tube provided at its upper discharge endvwith an end wall, and a cylindric chamber exterior to the wall and having sliding telescopic conheld at the eXtreme outward limit of its movement by the force of the outtlowingliquid, said 'main tube having an eccentric dischargeppening obliquely or spirally into said chamber, and a spray-orifice in the outer wall of the chamber out of line With said discharge-oriice, substantially as described.

'2. A spraying-nozzle comprising a tube closed at its end except for a discharge-orifice therein and provided with a sliding telescopic cap having a spray-orifice out of line with the discharge-orifice, and a stop for limiting the outward movement of the cap under the force of thel outilowing liquid, comprising an lelongated recess parallel with the axis of the tube, and a stud carried by the cap and engaging said recess.

3. A spraying nozzle comprising a main tube provided in its upper end with an eccentric outwardly directed discharge passage, a cap inclosing the end of the tube and ence of witnesses.` Y
