Abstract
A collapsible spreader having all parts pre-assembled that requires no tools for its transformation into an operative device and that includes a wheel assembly, a two-part frame member, whose lower part is affixed to the wheel assembly and supports a high-volume hopper as well as a collapsible support stand. The leg members of the lower frame are pivotally connected to the legs of the upper frame, such that the lower and upper frames when pivoted into an extended position from a trapezoidal loop and, when returned to their collapsed state, form a generally rectangular prism that includes the entire spreader device within its volume, namely the legs of the lower and upper frames, the hopper, the support stand, the seed-dispensing mechanism and the wheel assembly.
Claims19
A collapsible spreader having all pre-assembled parts, comprising
- a lower frame having a pair of spaced-apart diverging leg members, said leg members supporting a hopper means, a collapsible support stand means and an axle means, said axle means supporting wheel means, and dispensing means disposed on the bottom of said hopper means,
- an upper frame having a pair of spaced-apart diverging leg members, a handle means, and a flexible control means having one end connected to said handle means and another end connected to said dispensing means,
- pivotal means connecting said leg members of said lower frame with said leg members of said upper frame for allowing said upper frame to assume an end-of-swing extended state and a collapsed state with respect to said lower frame,
- adjustable fastener means on said pivotal means, said leg members of said upper frame being in a state of tension when said fastener means is adjusted to a tightened position, said tension in said leg members of said upper frame assisting said upper frame to assume said collapsed state when said fastener means is adjusted to a loosened position, and
- said collapsed state of said upper frame defining a a generally rectangular prism that includes said leg members of said lower frame, said collapsible support stand means, said hopper means, said wheel means, said dispensing means and said flexible control means.
A spreader comprising,
- a frame having a wheel means,
- a hopper means defining a generally rectangular pyramid supported by said frame means,
- a dispensing means disposed on a bottom face of said hopper means, said dispensing means including an opening in said bottom face of said hopper means,
- a guideway means bordering said opening and extending along said bottom face of said hopper means and part way up one side of said hopper means, said guideway means thereby extending in at least two angularly related directions, and
- a flexible articulated shut-off plate having flexibly connected multiple plate members disposed in said guideway for moving in said at least two angularly related directions over said opening and up said one side of said hopper means.
A spreader comprising,
- a frame means having a wheel means,
- a hopper means supported by said frame means,
- a dispensing means disposed on the bottom of said hopper means, said dispensing means including an opening in the bottom of said hopper means,
- a guideway means bordering said opening and extending along the bottom of said hopper means,
- a shut-off plate disposed in said guideway means for moving over said opening, and
- said shut-off plate is connected to a bow-like spring member whose extremities are in sliding engagement with a stationary runner means on said bottom of said hopper means, whereby said shut-off plate can move against the bias of said bow-like spring member to positions ranging from completely covering said opening through partially covering said opening to completely exposing said opening.
A collapsible spreader having all pre-assembled parts, comprising
- a lower frame having a pair of spaced-apart diverging leg members, said leg members supporting a hopper means and an axle means, said axle means supporting wheel means and a broadcast rotor means,
- an upper frame having a pair of spaced-apart diverging leg members and a handle means,
- pivotal means connecting said leg members of said lower frame with said leg members of said upper frame for allowing said upper frame to assume an end-of-swing extended state and a collapsed state with respect to said lower frame,
- adjustable fastener means on said pi means, said leg members of said upper frame being in a state of tension when said fastener means is adjusted to a tightened position, said tension in said leg members of said upper frame assisting said upper frame to assume said collapsed state when said fastener means is adjusted to a loosened position, and
- said collapsed state of said upper frame defining a a generally rectangular prism that includes said leg members of said lower frame, said hopper means, said wheel means, and said broadcast rotor means.
