Serial No. 287,735.
This invention relates particularly to spraying devices which do not require high pressure for effective operation; and the pr1- mary object is to provide a simple, compact and highly efficient device of this character which is in the form of a hand-carried unit:
Such a device is adapted for spraying 1nsecticide liquids, and for other analogous purposes.
The invention is illustrated in its preferred embodiment in the accompanying drawing, in whichl Fig. 1 is a plan view (slightlyl broken) of a spraying device v embodying t e inventlon; Fig. 2, a side elevational view of the same; Fig. 3, a sectional view on an enlarged scale, taken as indicated at line 3 of Fig. 1; and Fig. 4, a broken sectional view taken as indicated at line 4 of Fig. 3.
The device, in the illustration given, comprises an electric motor A; a fan-casing B attached to one end of the motor-casing and provided with a central air inlet B and with an outlet nozzle B2; a fan C housed in the casing B and mounted on an extension of the armature-shaft of the motor; and a liquidcontainer D depending from the underside of the nozzle B2.
The motor A has a horizontal axis. It comprises a casing 1 having at oneV end a cap 1l and at the other end an integral end-wall 1" provided with a bearing 1 and an armature (not shown) having a shaft 2 which extends through the bearing 1 and projects into the fan-casing.
The motor-casing is provided with an external circumferential lian e 3 which virtually forms an extension o the end-wall 1b,
o and the casing is provided further with an `annular ange 3 which is embraced by an inturned flange 4 with which the open end ofthe fan-casmg B is equipped. The flanges V3 and 4 are connected by cap-screws 5. The
intake B ofthe fan-casing is shown equipped with a screen 6. q
The nozzle B of the fan-casing is equipped at'its lower side with a cap 7 which is adapted to screw onto and make air-tight connection provided a short distance from its extremity with a vertical post 8 having an angular bore 8'l which has tapped end-portions into which are screwed the liquid-nozzle 9 which is centered in the nozzle B2, and the liquid-tube 10 which depends, through an opening 11, into the liquid-container. Back of the interior vertical post 8 is an inclined lug 12 formed integrally with the inner surface of the bottom wall of the nozzle B2. Through this lug extends a forwardly and downwardly inclined air-passage 12B which communicates through the opening 11 with the interior of the liquid-container.
In the illustrationgiven, the nozzle B2 is equipped at its end-portion vwith a Venturi tube, or sleeve, 13. This is shown as formed separately, but obviously may be formed integrally with the nozzle, if desired.
The fan C preferably comprises an aluminum disk 14 and curved blades 15 formed from sheet aluminum and secured to the disk by means of rivets 16. The disk 14 is provided with a central frusto-conical portion 14L having a perforated end-ange 14 which is secured to a sleeve 17 fastened onthe extremity of the armature-shaft 2, as by means of a cotter-,pin 18. The bearing 1 for the armature-shaft has a frusto-conical outer surface and projects freely into the recess provided by the frusto-conical central portion 14ll of the disk 14.
l The motor, the fan-casing, and the li uidcontainer depending from the nozzle o the fan-casing are intended to be hand-carried. The fan-casing may be of aluminum, and thus may be` made quite light. The device is equipped with a handle E which preferably is attached to the cylindrical member 1 of the motor-casing. The handle is hollow and has extending thereinto an electric cable 19 having a fiexible metallic covering 20 at the point where the cable enters the handle. This covering ma consist of a wire-winding.
The han e E inclines upwardl and toward the fan-casing and is rovide at its upper end with a flange 21 w 'ch is securedl to the motor-casing by means of screws 22.

The flange 21v encircles anopening 23 withf 100i y -by Letters Patent, is
which the cylindrical member 1 o the motorcasing is provided. The electric cord 19 has one conductor 19.a extending directly vto the motor, and another conductor 19b extending to a switch 24 which is carried by a removable plate 25.
The handle E is in the nature of a pistolgrip handle by means of which the operator can support the spraying device at arms length while the spraying operation is being performed. The handle is equipped at its ower end with a foot-piece 26 which is' at.
the same level as the bottom of the container D; hence, the spraying device is capable of resting stably upon a table in the 4position shown in Fig. 2.
The switch 24 is conveniently located at the upper portion of the handle. The device is put into operation simply by turning on the electric current. This results in forcing air through the nozzle B2. Suction is created through the tubes 9 and 1() and the liquid' discharging rom the inner nozzle 9 is sprayed by the current of air. A portion of the air enters through the port 12a into the container D, and aids in elevatin the liquid which is to be sprayed. The enturi tube which cooperates with the inner nozzle 9 adds to the efficiency of the device.
The fan C rotates in the direction indicated by the arrow in Fig. 3, and the concavities of the blades 15 are presented in the direction of rotation. A
The device, as a whole, is extremely eicient and may be made so light as to enable the com bined motor, blower, and container to be readily held at arms length by the operator during the spraying operation.
The foregoing detailed description hasbeen given for clearness of understandin only, and no unnecessary limitations shoul be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
