Abstract
A broadcast spreader constructed from two separate and rotationally molded parts; one molded part integrates the handle and hopper assemblies while the other molded part forms the base assembly that supports the wheels for the spreader. A pair of dovetail-like connection between the molded parts assures a strong and tight fit and proper alignment therebetween. Also provided are a self-aligning bearing for the rotor shaft and a single control for simultaneously operating a deflector plate and an auxiliary dispensing member for the spreader.
Claims10
A two-part spreader for dispensing soil-treating materials comprising,
- a handle assembly and a hopper assembly formed from a first molded member having a connector means integral therewith,
- a base assembly including a pair of leg members formed from a second molded member having a connector means integral therewith,
- a wheel assembly supported by said pair of leg members,
- a dispensing means disposed at the bottom of said hopper,
- a drive means connected to said wheel assembly for driving a rotor plate disposed below said dispensing means,
- control means on said handle assembly connected to said dispensing means, and
- said connector means of said first molded member cooperating with said connector means of said second molded member to rigidly secure together said first and second molded members to thereby form said two-part spreader.
A spreader for dispensing soil-treating materials comprising,
- a handle assembly, a hopper assembly and a base assembly,
- a wheel assembly supported by said base assembly,
- a drive means connected to said wheel assembly,
- a rotor plate connected to said drive means,
- a dispensing means and an auxiliary dispensing means disposed at the bottom of said hopper assembly,
- a deflector means pivotally disposed at the side of said hopper assembly for partially blocking the throw of materials from said rotor plate,
- a first control means on said handle assembly connected to said dispensing means,
- a second control means on said handle assembly connected to said auxiliary dispensing means,
- a third control means on said handle assembly connected to said deflector means for pivoting said deflector means from an inoperable to an operable position, and
- a single lever means connecting said second control means and said third control means, whereby operation of said single lever closes said auxiliary dispensing means simultaneously with pivoting said deflector means into said operable position.
A spreader for dispensing soil-treating materials comprising,
- a handle assembly, a hopper assembly and a base assembly,
- a dispensing means disposed at the bottom of said hopper assembly,
- an axle assembly having a pair of wheels supported by said base assembly,
- a drive means connected to said axle assembly,
- a rotor shaft connecting said drive means to a rotor plate and being generally perpendicular to the axis of said axle assembly, and
- a bearing support means disposed in the bottom of said hopper assembly for rotatably supporting a spherical bearing member having an aperture therethrough through which said rotor shaft extends, whereby said rotor shaft is self-aligning with respect to said axle assembly should a non-perpendicular condition exist between the axis of said axle assembly and said rotor shaft.
