Description
' Oct. 22, 1929. K. A. PETERS ELECTRIC SAND SPRAYER Filed May 9/ 1927 INVENTOR lfwrrAuusr Perses BY OQ 1 ATTORNEYS.
Patented Get. 22, 1929 UHTD STATES KURT AUGUST PETERS, OF SAN FRANCISCO, CALIFORNIA ELECTRIC SAND SPRAYER Application fi1ed May 9, 1927.
The present invention relates to improvements in sand sprayers and its general object is to provide an electrically operated sand sprayer the parts of Which are combined into one unit and adapted for convenient manipulation by hand.
Another object of the invention is to provide a sand sprayer of the character described in which the sand is discharged into a conduit in which a forced draft is created, the construction of the conduit being such as to thoroughly separate the individual particles of sand from one another and the conduit being provided with a tapered nozzle discharging the sand particles in a fine stream.
Further objects and advantages of the invention will appear as the specification proceeds.
The preferred form of my invention is illustrated in the accompanying drawing, in which Figure 1 shows a side elevation of my sand sprayer; and
Figure 2 a bottom plan view thereof.
lNhile I have shown only the preferred form of my invention I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached Without departing 30 from the spirit of the invention.
In its preferred form my sand sprayer comprises a conduit 1 presenting an offset 2 intermediate the ends thereof so as to provide a front section 3 and a rear section 4:, the
35 two sections being parallel but dis-aligned. The front section 3 terminates at its front end in a nozzle 6, which is preferably flattened, as appears particularly Well from Figure 2, so as to discharge through a narrow slot 7 and the rear end of the rear section 4 is slightly tapered as shown at 8 and has a housing 9 fixed thereto, the housing accommodating a fan 11 adapted to suck air through the open end 12 of the housing and 45 to discharge the same through centrifugal Serial No. 189,964.
force into the conduit 1. A motor 13 is mounted coaXially with the fan and has a handle 14 extending downwardly therefrom, the tip of the handle being connected to the front section of the conduit by means of a brace 16.
Above the front section is mounted a funnel-shaped hopper 17 presenting a cylindrical upper portion 18 adapted to be filled with sand, the hopper 17 discharging into the front section 3 through a small opening 18. It will be noted that the hopper 17 is disposed so as to lean against the upper edge of the offset 2 and is held in place by means of a brace 19 secured to the cylindrical portion of the hopper as shown at 20, and to the rear section of the conduit 1 as shown at 21.
The wires 22 connecting to the motor 13 may pass through the handle 14:.
In use the sand is discharged in small quantities from the hopper into the conduit while the fan when operated by the motor creates an air blast, which carries the sand along and discharges the same through the nozzle 7 in a flat stream. It will be noted that the hopper is mounted immediately in front of the offset and this arrangement causes eddy currents to be formed in the air blast immediately adjacent the discharge area of the hop per whereby the sand is thoroughly stirred up and agitated so that all the individual particles are well separated from one another and any small lumps that may have formed are broken up.
I claim:
1. In a sand spraying machine of the character described, a conduit terminating in a nozzle at the front end thereof, means for feeding sand thereinto transversely to its axis, a fan at the rear end of the conduit adapted to direct a current of air thereinto in the direction of the nozzle, a motor mounted (Jo-axially with the fan in driving relation thereto and a handle extending transversely from the motor, the conduit being set-off rearwardly of the feeding means for creating eddy currents breaking up the sand in fine particles. v
2. In a sand spraying machine of the character described, a conduit, means for feeding sand thereinto and means for directing a current of air therethrough, the conduit bring set-off rearwardly of the feeding means for creating eddy currents breaking up the sand int-0 fine particles.
KURT AUGUST PETERS.
