Description
Patented Oct. 30, 1934 PATENT OFFICE SPRAYER Ira 0. Altenburger and Nicholas W. De Frees,
Hastings, Minn., assignors to H. D. Hudson Manufacturing Company, Chicago, 111., a corporation of Minnesota Application January 25, 1932, Serial No. 588,648
1 Claim.
This invention relates to improvements in Sprayers particularly designed for applying insecticides, floor oils and the like, and provides a supply tank which is portable and which can be carried in axially upright position in the manner of a knapsack, along with combined mixing and spraying means having a handle formed by liquid and air pipes, in turn connected by flexible supply conduits with the' tank. The present device providesa mixing nozzle of the so-called automatic type in which air and liquid are combined in proper proportions for discharges, so that the spray so produced has greater carrying power than is obtainable from ordinary compressed air sprayers.
Objects are to provide a cheap and etficient device.
Features of the invention include the application of a mixing nozzle to a portable supply tank; the use of the liquid and air supply pipes to form a handle; the utilization of the mixing casing as means for securing the handle-forming elements in operative relation; the specific form of the mixing casing; the utilization of the valveoperating lever support as means for securing the pipe sections in operative position; the manner of connecting the sprayer handle with the tank; the use of flexible conduits for making this connection; and generally to all details of construction illustrated.
Objects, features and advantages of the invention will be set forth inthe description of the drawing forming a part of this application, and in said drawing,
Figure 1 is a View showing the complete device with portions of the tank wall and air and liquid delivery pipes broken away;
Figure 2 is a detail longitudinal section illustrating the mixing valve; and
Figure 3 is a cross-section on line 3-3 of Figure 2 further illustrating the mixing valve.
The introduction of air into the tank acts to produce a liquid pressure therein, as well as the air pressure, one to supply liquid under pressure to a mixer and sprayer unit later to be described, and the other to supply compressed air to that unit. To this end, the tank is provided in its top with a short tube 20 suitably soldered as at 21 and having its receiving end at the highest point of the tank. The tank is also provided with a second tube indicated at 22 which passes through the top 5, and is soldered thereto as at 23. This tube extends substantially to the bottom of the tank and is angularly cut as at 24, the cut facing toward the center of the tank. Liquid enters the tube at a point near the bottom of the tank, and below the bottom or valve end of the pump.
To the tube 20 is secured a flexible tube 26 and to the tube 22 is secured a flexible tube 2'7. These tubes are respectively connected with pipes 28-29, portions of which pipes form a handle for the mixer and sprayer unit; a feature of the invention. The portions 30-31 of the pipes 28-29 are adjacently disposed in spaced parallel relation as shown, to form a handle. The pipes are held in their handle-forming positions at one end by means of a casing 32 of the mixing and spraying unit, and at the other end by a cliplike support to which is pivoted as at 62, the valve-operating lever 63. This is a valuable feature.
Another feature of the invention relates to the mixing and spraying unit structure shown in Figures 2 and 3. The casing is so formed as to act as a connector for holding the handle-forming and supply conduit elements in operative relation, and is generally indicated by numeral 32. The casing is formed to provide the communicating, axially aligned bore portions or chambers 40-41. The casing is bored at the rear as at 42 to provide a sliding bearing for a valve stem 43 and the bore portion 40 is threaded as at 44. A cap, valve seat-forming and valve-centering member is indicated at 46 and is provided with a reduced portion 47 having threads cooperative with the threads 44 for removably securing the head. The head has a capping portion 48 which cooperates with the end of the casing 32 to close the chamber 41, a suitable gasket 49 being interposed.
The casing is provided with lateral enlargements respectively indicated -51. The enlargement 50 has a bore 52 which communicates by passage 53 with the bore 40. The enlargement 51 has a bore 55 which communicates by means of the passage 56 with the chamber 41. The air supply pipe 29 is connected to the casing by insertion in the bore 52 and the liquid supply pipe 28 is connected to the casing by insertion in the bore 55. The enlargements 50-51 provide means for securing the combined handleforming and conduit sections at one end in 0perative or handle-forming relation. By this arrangement, that part of the casing 32 which has the bore portion 40 is arranged-between the pipes and the valve stem 43 lies within the plane of the pipes. The pipes are connected at or near their opposite ends by a support 60 having the form of a U-shaped clip,- clampingly securedby means of screw 61. Upon this support is pivoted as at 62 a bell-crank lever 63, and to this lever is pivoted, as at 64, a wire 65, the opposite end of which is operatively connected with the stem 43 to control the valve. The wireis arranged substantial- 1y within the plane of the pipes so that the wire can perform its valve controlling function without being interfered with or without interfering with a hand gripping the handle-forming tubes, between the lever and the valve casing. It is conceivable that the clip 60 can be moved to a point nearer the mixing valve to provide a greater gripping area for that hand which operates the lever, and so as to avoid gripping of the rubber pipes 26-27. The pipe portions 303l may be additionally braced by any suitable means indicated at 6'7 and, in this instance, this means is hollow so that the valve-operating wire 65 passes loosely therethrough.
Returning to the details of construction of the mixing and spraying unit: A valve seat '70 is provided in the portion 4'7 and has the form of a truncated cone and is convergent towardgthe dis; charge orifice '71. The tapered Seatmergesinto the cylindrical centering-guide bore portion '72 5- which lies between the small end of the seat and the discharge orifice '71. Cooperative with the tapered seat is a valve member having a correspondingly tapered portion '73, which merges into a reduced cylindrical portion '74 and this reduced portion has longitudinally extending fins '75 cooperating with the bore portion '72 to center the Valve, and to provide a non-vibrating slide bearing therefor, and yet allow for free flow of fluid past the valve when open. The forward end of the reduced portion '74 has a socket (not shown) into which is fitted a plug-like valve '76 of leather or other suitable material. This valve is cooperable with the discharge orifice 71 to close it when the tapered valve is closed.
A suitable leak-proof stuifing'7'7 surrounds the valve stem as shown, and a spring '78 normally holds the valve in closed position, one end of the spring engaging the end of the portion '73 of the valve and the opposite end engaging a washer '79 which presses the packing about the stem and orifice 42 to obtain a seal. Referring to Figure 3-, it will be noted that tangential passages lead outwardly from opposite sides of the bore 72 to chamber ll. By this means, the liquid is sucked in at' the outer periphery of the bore through the passage 80 and given a whirling motion which facilitates mixture with compressed air, moving outwardly through bore portion 70.
We claim as our invention: I v
A device of the class described comprisinga pair of tubes arranged in spaced relation to form a handle, a casing having means securing the tubes and having passages for the reception of and mixing and spraying of fluids delivered by the tubes, some of which passages communicate with the handlc-forming tubes, valve means for controlling mixture of fluids delivered by the handle-forming tubes, valve operating means carried by the handle, and a wire operably connecting said operating means for controlling the valve means, said wire lying substantially within the plane of and between the tubes.
