Definitions
- the present inventiont relates to improvements in portable spray devices and, more particularly, to motor/ blower units for devices of the type which are designed spraying of fluids.
- a sprayer device'transportable on the back of an individual i for dispensing insecticides and other crop-treiating agents and, in'general, for the distribution of gases, liquids, pow- H ders and aerosols at locations remote from stationary sources of power andmobile' unitsof large size such devices, when provided witha prime mover, did not find widespreaduse as a;consequence ofsevenal structural disadvantages.
- the blower means were disposed proximal to the support frame while the 'motor or"engine,'-with its cylinderfwa spaced axially rearwardly therefrom, the magneto and other parts of the ignitionlmeans beingprovided at the rearmost part of the I shaft. Since the magneto comprises, as is customary,a'
- Another object of my invention is to provide, in a systern of this type, means for eliminating the inconvenience of a large moment of force as a consequence of the location of at least the massive portions of theignition means at a position remote from the carrying frame or support.
- Yet anothenobjectof this invention is to provide a motor/blower arrangement having aniniproved ignition system.
- the fluid-displacement means comprises an impeller-type rotor, forming a flywheel for the motor, received in the blower housing, at least part of the magneto means of the. ignition system being mounted in this housing.
- the costs and weight involved in disposing the magneto in the blower the retention of the breaker points upon-the motor shaft at a location remote from the blower, since these breaker points generally'have an insignificant weight, even when their cam is considered, and are thus disposed in a highly accessible location for service.
- the connection between the field coiland the breaker points'in an engine system of the type described is usually a low-tension conductor so that, losses are avoided.
- the high-tension winding of the magneto can be connected directly tothe spark plug or plugs of the engine. Itfshould be noted that it is preferred'to use a two-cycle engine for this purpose, the
- the motor/blower assembly can be mounted upon a carrying device of the type described in the commonly assigned copending application Ser. No.
- FIG. .2 isfa side-elevational view, partlyin axial crosssection, showing the motor/blower unit in greater detail;
- FIG. 3 is a diagram showing an ignition system suitable for use with thisunit. I 3
- FIGS; 1 and 2 there is shown a portable spray device adapted to be mounted upon the back of the user and Y comprising a support frame ill, of the type described in carrying plate 14.
- the frame can includeva pair of lateral supports 13' between which a plate 14 is provided, suitable webs '15 reinforcing the junction between the receptacle 11, the tank 12 and the fort, the" carrying frame should be provided with a curvature about a generally 'vertical axis so as to fit snugly
- the motor/blower unit as .previously'rnentioned, comprises an internal-combustion engine 3, which is here shown to be of the'onercylinder, two cycle type, rnounted 'ia flanges 3"on the rear plate 1' vof a blower housingl to pedestals integrally formed on the carrying frame it) 1 via the usual bolts and, if desired,.resilient feet.
- lower housing 1 is so mounted that its axial intake opening in 'is spaced from the carrying plate 14 to permit induction-of airf into the interior of the blower whence this not'further described but known per se, are provided to which, in turn, oan be formed with lugs 1 for connection r air can ib e displaced by an'impeller 2 mounted upon the 7 output shaft "3",of engine 3.
- This impeller .sha ft functions' as a flywheel for the engine andmay have an annularportion 2' whichcan be aring integral with but rearwardly of the impeller. disk 27? carrying the radial vanes or blades 2a, Y
- the ignition system'of this engine comprises, according to the inventiomthe usual spark plug iirz and a magneto field coil 6; which ismounted upon, the blower housing' If and at least partly received therein.
- the pole piece 7 of this field coil extends radially in closely spaced relationship with the impeller .2, which is provided with a permanent i magnet 4 (FIGSQZ and 3) adapted to generate the igniv tion pulse, the field coil'd being connected-to-the' spark plug 34; of engine cylinder 9 by means of the ignition 7 cable 8. Since this magnetoarnangement 4,6,.
