Abstract
A trailer for livestock and other loads comprising a frame resting on an axle member on which the vehicle wheels are mounted. The axle member is provided with two arms, one pivoted on each side of the trailer on supports extending above the frame. The wheels are swingable forwardly about the pivots to a position over center with respect to the pivots and by blocking the wheels and forcing the trailer rearwardly it is raised by the pivoting arms and tilts downwardly toward the rear until the arms strike stops limiting the swinging movement of the arms. A drawbar is pivoted to the frame on a horizontal axis parallel to that of the wheels and is positioned so that rearward force when the wheels are blocked tends to tilt the trailer. The trailer is arranged for easy handling by one man without the use of hydraulic jacks or the like.
Claims7
A trailer for carrying livestock and other loads comprising;
- a rigid flat frame for supporting a floor,
- means providing rigid supports connected to and extending above said frame on each side thereof,
- a pair of wheels for said trailer mounted on an axle member extending therebetween and positioned below said frame,
- a pair of spaced parallel mounting arms rigidly secured to said axle member and extending laterally normal thereto, one on each side of said frame,
- means for pivoting said arms on said rigid supports a substantial distance above said frame,
- the length of said arms from said axle member to the pivots on said support being substantially greater than the height of said pivots above the bottom of said frame, and said arms extending at an angle rearwardly of of said supports with said frame resting on said axle member,
- said arms being swingable to a forward position over center with respect to said axle member and against stop means rigidly secured to said frame below said supports,
- a drawbar pivotally mounted on the bottom of said frame for swinging movement in a vertical plane whereby when said wheels are blocked and the drawbar is forced rearwardly said arms rotate about said pivot and lift and tilt said trailer until said arms engage said stop means thereby locking said trailer in a predetermined tilted position for loading or unloading.
