Abstract: A boat trailer including a triangular frame comprised of a pair of identical, integrally formed frame sections connected by threaded fasteners. The running gear assembly and boat supporting structure is attached to the frame by fasteners to form a durable, inexpensive boat trailer that can easily be assembled and maintained by the user.

Abstract: A boat hoist including a novel level lift suspension system which results in even application of forces to points on the moveable platform remote from the point of attachment of the lifting device, thus eliminating twisting of the loaded platform.

Abstract: An adjustable length boat trailer has a rigid framework mounted on an axle supported by wheels. The framework has a rearward U-shaped portion and a pair of converging arm sections at its forward end. A T-shaped elongated tongue member is slideably and releasably secured to the framework. The tongue member has a forward elongated shaft portion having a hitch connection and rearward outwardly disposed crosspiece arms. The shaft portion is slideably and releasably secured between the converging arm sections while the crosspiece arms are adjustably and releasably secured to the U-shaped portion of the framework. Each of the crosspiece arms pivotally supports a roller assembly which is moveable along the length of the arm.

Abstract: A ducted fan unit is installed in a scale model airplane the unit being positioned centrally within the hollowed fuselage, and including an engine, with fan assembled thereto, secured to an aerodynamically sleek mounting bracket, the mounting bracket is secured to a cowl and positions the fan within the forward portion of the cowl, the rearward portion of the cowl includes a flow straightener having radially disposed spokes with curved forward portions to deflect the air flow linearly.

Abstract: This invention relates to motor mounts in general, and more specifically to a universal motor mount to be employed in a model airplane, which will allow the motor to be disposed at any desired angle or altitude to accommodate engine or exhaust equipment beneath the engine cowling.

Abstract: An apparatus for handling bales having the capability to engage, lift, transport and feed bales of hay. A frame is adapted to be connected to a three-point hitch of a tractor. Pivotally connected to the frame along an axis substantially parallel to the direction of movement of the tractor is a first substantially L-shaped member. A first bale arm is pivotally attached to the first member and has a rotatable hub attached at the lower end thereof for engaging one end of a bale. A second bale arm is pivotally attached to the first bale arm and has a hub rotatably attached to the lower end thereof for engaging the other end of a bale. A mechanism for pivoting the second bale arm with respect to the first bale arm allows a bale to be engaged by the hubs without the need for the operator of the apparatus to dismount from the tractor. A rotatable member is disposed on the lower end of the first member and has a mechanism for selectively causing rotation thereof.
