Abstract: Disclosed herein is a trailer for carrying a machine having a frame supported by a wheel, the trailer including a trailer frame having a forward frame end and a rearward frame end, and a ground engaging trailer wheel attached to the frame adjacent the rearward frame end for supporting the trailer frame for movement on the ground and supporting the trailer frame for movement between a generally vertical position wherein the machine can be attached to the trailer frame and a generally horizontal position wherein the machine can be supported on the trailer frame. The trailer also includes means for supporting the machine wheel connected to the trailer frame adjacent the trailer wheel, and a pivotable locking arm supported by the frame for releasably restraining the machine wheel on the wheel supporting means, the pivotable locking arm being movable between a first position wherein the machine wheel is restrained against the wheel supporting means and a second position spaced from the first position.

Abstract: This is a new and unique machine which organizes older, recognized and established methods of handling objects and machinery into a more economical, efficient method by recombining articles of present day usage into a new concept. An ordinary conventional automotive hydraulic jack is used to replace the fixed jacking arrangement found on machines of this type. The use of a threaded screw mechanism working in conjunction with a moveable trolley arrangement makes it easier to handle a load and makes it possible for this machine to accomplish comparable results in the handling of objects and machinery as was formerly required by two different and distinct machines.

Abstract: A spool having an elongated barrel has a strap supported at one end at a bottom flange on the barrel with the strap passing upwardly therethrough out of the upper end thereof. The strap is removably attached to the bottom flange. A handle is affixed to the strap portion which extends beyond the upper end of the spool. A rigid frame having an upright portion is affixed to a base supported by casters. The frame has a member rigidly affixed to and transversely extending from the upper end of the upright portion which overhangs the spool. A lever having a transverse portion near one end is pivotally connected at the distal end of the transverse portion to the frame member. An arm is pivotably secured at one end to the upright portion and at the other end is engageable with the spool handle. A link is pivotably connected between said arm and the transverse portion to provide a toggle linkage.

Abstract: A jack member onto a pair of which members a vehicle can be driven and then raised to a position inclined to the horizontal. The jack members are used more particularly for stowing vehicles in containers on a number of support frames. The jack members raise the vehicles so that they are supported at an angle to the horizontal with their wheels held in wheel support cradles attached to the frames. The jack members each comprises an approach ramp and a lifting ramp pivotally connected at one of their ends on which the vehicle is initially aligned and supported prior to being elevated at one end for inclined support on the vehicle frame.

Abstract: An object, such as a snowmobile, having transverse bars at the ends is prepared for storage by engaging attachments with the bars, the attachments preferably having casters disposed so that the object must be lifted slightly in order to bring the casters directly under the engaged bars. Each of the attachments is either forced over-center to engage an abutment, or is secured otherwise against rotation out from under the bar. The usual towing coupling of a snowmobile is used for the latter purpose.

Abstract: A dolly for lifting one end of a long open web steel joist or truss and for then conveying the joist to and fro along a steel structural beam member having a horizontally disposed web which normally restingly supports the joist. The dolly includes a main body which carries an axle having a wheel journaled thereto for runningly and ridingly engaging the beam member as the joist is manually maneuvered into its optimum position. A lever or handle is fixedly attached to the main body and coacts with the wheel (which acts as a fulcrum) to lift the heavy joist as the handle is manually urged downwardly. Various embodiments of structure for engaging and supporting two different type joists are disclosed herewith.
