lSIECfIFItiATION forming part of Letters Patent No. 417,464, dated December 17, 1889. Application ned July 31, 1889. serai No. 319.330. (No model.)
To @ZZ 'whom it may concern: Y
Be it known that I, J oHN BEAN, of Los Gatos, Santa Clara county, State of California, have invented an Improvement i'n Spray-Nozzles; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to the class of nozzles or tips specially adapted for spraying and used in the treatment of infected trees, shrubs, vines, duc.; and my invention consists, essentially, in a novel imperforate packing plate or sheet controlling the nozzle-passage and exit-port.
It consists, also, in the nevel constructions, arrangements, and combinations hereinafter fully described, and specifically pointed out in the claims.
The object of my invention is to provide a spray-nozzle capable of effective operation under a smaller pressure than usual, and one which will not be affected injuriously in its adjustable or working parts by the liquid passing through it.
Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my spray-nozzle. Fig. 2 is a longitudinal section of the same. Fig. 3 is a perspective View of the plate or sheet C. Fig. 4 is a perspective view of the clamp-plate D and regulating-lu g E. Fig. 5 is a view of the nozzle or tip with the parts C and D removed. Fig. 6 is a section of a modified or double nozzle or tip. Fig. 7 is a front edge View of the same.
Ais the nozzle or tip, having at its rear end the internally-threaded socket of., by which it is screwed upon the hose-pipe. The passage a( of the nozzle or tip extends straight through it and terminates in a slight groove which forms the exit-port b. This groove is made l in the end of a wide bearing-surface B, formed on the front of the nozzle or tip, said surface being here shown as inclined to the plane of the passage a', whereby it partially intersects and exposesl said passage just back of the exit-port. It is not essential that this bearing-surface shall be so inclined, for it is only necessary that the passage shall lie exposed in it for a short distance back from its exit end, and therefore the relative arrangement of passage and surface may be in any manner giving-this result.
Upon the bearing-surface B is laid a plate or sheet C, made of suitable packing material which will forml a tight joint, and for the best results this material should be flexible, such as rubber, as this will not be injuriously affected by the liquid used. This plate or sheet C has about the same superficial surface as thebearing-surface on which it rests, its forward edge being about iiush with or just a little short of the front edge of the bearingsurface. it at all, but is entire, and, lying on the bearing-surface B, it covers and completes at its middle front portion the exposed end of passage a and lies just above the groove or lport b.
E is a clamp-plate placed on the imperferate plate or sheet C and secured by screws d, which pass down through the plate or sheet C and are seated in the bearing-surface B, so that s.n id plate or sheet C is firmly clamped and bound betweenrthe plate D and the surface B, thereby serving in addition to its primary function of a sprayer, as will be presently explained, the secondary function of a packing-washer, making a tight joint. The forward edge of the clamp-plate D comes out iiush with the forward edge of the bearingsurface B, and said plate is made forked to receive the regulating lug E, which is pivoted to the plate at e and has an upwardly-extending arm c at its back.
Rising from the nozzle or tip A is a piece a2, in which is seated the adjusting-screw F, the forward end of which bears against the arm e of the regulating-lug E. The lug E rests upon the imperforate plate or sheet (E, and its forward end on its under side is made with a slight groove or concave e2 in a plane just above the groove or porth in the surface B below. p
The operation of the device is as follows: In the broadest view of its action the clampplate D is to be regarded as a continuous surface, as if the lug E formed -a rigid part of it. Now, this plate being screwed down upon-the imperforate plate or sheet C causes the latter to serve as a packing, and also pressing and This plate or sheet has no hole in IOO biting down upon said plate or sheet holds the center of its front edge downL directly over the exposed forward end of passage a and over the port b, and partially conforming thereto by reason of its flexibility, sufficiently' obstruets said passage and port to convert the liquid into spray as it. issues from the port. To improve this result, the slight groove or concave e2 lends itself by allowing the upward curve of the edge of the flexible plate or sheet, and thus giving a nucleus to the issuing spray and concentrating it. Now, to understand how the spray is regulated in dcgree, the clamp-plate I) and lug E are to be regarded as separate pieces, the former holding the flexible plate or sheet (l and the latter variably affecting' its middle portion. For a. fine spray` the screw F is set up and its end bearing on the arm e of lug E turns said lug down, so that it pinches the flexible plate or sheet down more closely into the exposed end of passage a and port b, and fora coarser spraythe screw is run back to relieve the lug, which thereupon relieves the plate or sheet.
In Figs. 6 and I have shown a double construction. In this I have a bearing-surface B on each side of the nozzle or tip, said surfaces converging forwardly to a very thin edge. These surfaces the passage d intersects, as before. An in'iperforate plate or sheet C laid on each surface, one of said plates or sheets being clamped by a plate (here lettered (Z) similar to plate l), with the exception that it is a continuous one having no regulating-lug E in it, but having a small `groove or concave d in the center of its forward edge, similar to the groove or concave c? in the lug E. It will be seen that in this double construction the imperforate plates or sheets act similarly on both sides, while the lug E on one side is sufficient to regulate both, though it is obvious that a second lug, such as E, might be used.
In the use of spraying-nozzles in which a rotary or movable valve or plug is employed, a serious difficulty is encountered arising from the fact that some of the liquids used eorrode the metal of the nozzle, resulting in interference with the operation of the movable parts; but in my nozzle the imperforate plates or sheets, being made of rubber, are not injuriously affected, and they protect, in their capacity as packing, the movable lugE from contact with the liquid; consequently there is no danger of the nozzle ever getting -out of working order. ,Y or is there anything Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
