Abstract

The trailer apparatus is adapted for loading and transporting a farm unit, such as a cattle squeeze chute, that has a rectangular shaped main frame. The trailer includes a U-shape frame with ground wheels outwardly mounted adjacent the rear or free ends of the leg sections. With the leg sections at opposite sides of the chute main frame the trailer is manually backed up and tilted upwardly and rearwardly about the wheel axes thereof to releasably engage the rear ends of the leg sections with corresponding laterally extended support members on the main frame of the farm unit. On then tilting the trailer downwardly and forwardly the main frame of the squeeze chute is releasably connected to forward portions of the leg sections after which the trailer is moved to a substantially horizontal position for connection of its front end with a towing vehicle.

Claims2

Dependent claims

A trailer apparatus for lifting and transporting an article of substantially rectangular parallelepiped form having a pair of outwardly directed vertically oriented apertured support plates oppositely positioned at the bottom edges of such article near one end thereof, the aperture in each such support plate constituting a substantially rectangular opening therethrough which is elongate in the horizontal direction, comprising

a substantially U-shaped trailer frame member adapted to straddle such article to be transported,
a ground wheel mounted on the outer side of each leg of said U-shaped frame member near the free end thereof for supporting said frame member above the ground, said free ends constituting the rear portions of said frame member,
a tongue member mounted on each free end of said U-shaped frame member and extending upwardly and rearwardly therefrom, each said tongue member having a cross-sectional perimeter at its forward end substantially equal to the perimeter of a corresponding one of such apertures in such support plates on the article to be transported, said tongue members being tapered rearwardly to a progressively smaller cross-sectional perimeter, each said tongue member thus substantially filling such corresponding aperture when fully inserted therein to preclude substantially all movement relative thereto except for limited pivotal movement in the vertical plane through the corresponding leg of said frame member, and
means on each leg of said frame member forward of said wheels for connecting said frame member to such article to be transported at a location on the latter remote from such support plates thereon,
whereby the full insertion of said tongue members into corresponding ones of such support plate apertures in wedging relationship therewith prevents torsional movement of said frame member which would otherwise occur as the weight of such article to be transported is borne by said frame member.

2 more elements

A trailer apparatus for loading and transporting a farm unit having a rectangular shaped horizontal main frame with a pair of forwardly positioned transversely opposite upright members, and a pair of rearwardly positioned transversely opposite laterally outwardly projected support members, said trailer apparatus including:

a. a generally U-shaped frame having a front base section and rearwardly extended leg sections transversely spaced a distance apart slightly greater than the transverse dimension of said main frame.
b. a pair of ground wheels corresponding to said leg sections, each ground wheel rotatably mounted on an associated leg section adjacent the rear end thereof and at a position outwardly from said U-shape frame,
c. first coacting means on the rear end of each leg section and to each of said support members for releasably connecting together said rear ends and said support members when said U-frame is tilted about the axis of said ground wheels to a rearwardly and downwardly inclined position,
d. coacting means on each upright member and adjacent leg section for releasably connecting together said upright members with forward portions of said leg sections when said U-frame, with the support members connected to the rear ends of said leg sections, is tilted about the axes of said wheels to a forwardly and downwardly inclined position in substantially the plane of said main frame,
e. said first coacting means including an upwardly and rearwardly inclined tongue member extended rearwardly from the rear end of each leg section with the sides thereof tapered inwardly toward each other from the forward end thereof, and
f. each laterally projected supported member having an elongated opening extended transversely of said main frame, said elongated openings spaced transversely of said main frame a distance apart equal substantially to the distance between the longitudinal axes of said leg sections, and each of said elongated openings being of a size and shape corresponding substantially to the transverse cross-sectional area of a corresponding tongue member at a position adjacent the forward end thereof to provide for the insertion of each tongue member within a corresponding elongated opening to a wedged position wherein the cross-sectional perimeter of each such tongue member at the forward end thereof substantially fills the corresponding elongated opening, whereby substantially all relative movement therebetween is precluded except for limited pivotal movement in the vertical plane through each said extended leg section.
