Abstract: The invention comprises a device for towing and transporting a roll of hay, said device having a pair of arms with points at their rearward outer ends for engagement into a roll of hay. The pair of arms are pivotably connected at their forward ends. A lever means is provided having means at its forward end for attachment to a power drive vehicle. The lever means acts upon being moved forward to lever the rearward outer ends of the device toward one another, whereby, with the device attached to the vehicle and a roll of hay attached to the device, the forward movement of the vehicle moves the device forward and also moves the lever forward to tighten the hold of the device to the roll of hay to assure the device tows the roll of hay forward.

Abstract: The invention comprises an improvement in a locking puller device. The locking puller has three pivotally mounted jaws and a cam ring which moves forward to pivot and lock the jaws about an object. The improvement comprises a projecting lug structure suspended only from the cam ring which projects beneath the under surfaces of the jaws to cam the jaws apart as the cam ring moves rearward with the projecting lug of the cam ring engaging the undersurfaces of the jaws. The under surfaces of the jaws follow a tapered path relative to the movement of the cam ring so as to cam the jaws apart.

Abstract: The invention comprises a locking puller for pulling such objects as the inner race of a bearing, gear, or sprocket off of shafts. The puller has three jaws each pivotally mounted to a collar to enable the jaws to pivot radially toward one another to engage such objects to pull such objects off of a shaft. The apparatus has a cam ring with a triangular shape and rearwardly extending braces which are fixed to a rearward ring. The collar has a rearwardly threaded cylindrical portion with a nut threaded onto the cylindrical portion. The nut has an annular groove with the rearward ring rotatably mounted to a nut in the groove. The cam ring surrounds jaws at a location forward of the pivotal mounting of the jaw. The jaws are tapered.
