Abstract: A trailer for hay bales which includes a wheeled body having a bottom provided with an opening beneath which an elongated platform is supported for vertical movement the forward end of the platform being adapted to successively pick up bales of hay from the ground and form a row of bales following which the platform is moved upwardly through the opening to deposit rows of bales in a stack successively within the body interior, each stack being moved transversely within the body interior by a slidably positioned side panel until the body interior is filled with stacks of bales in side-by-side abutting relationship following which all of the stacks are pushed out of the rear end of the body at a suitable location by a slidably disposed front panel on the body.

Abstract: A wire feed mechanism for use in conjunction with a nail forming machine. The wire feed includes a wire clamping device connected through appropriate linkages to a reciprocating hammerslide located within the nail machine. The hammerslide is movable between extended and retracted positions for forming the nail head. Due to the direct positive linkage between the hammerslide and the wire clamping device, feeding movement of the wire into the nail machine is achieved as a direct result of hammerslide movement, thereby obviating the need for cumbersome and elaborate linkages currently in use.

Abstract: A two speed motorcycle hub transmission in which the wheel may be driven at a one to one, or at a lower speed by a sliding clutch changing the drive from having the wheel locked to the drive shaft, to a planetary system the drive shaft driving the sun gear.
