Abstract
A machine for compacting in one series of operations up to a truckload of snow removed from city streets and the like. The machine has a hopper for receiving such snow, a compacting chamber and a hydraulically operated blade for compacting snow in the chamber. The compacting chamber is positioned below and to one side of the hopper whereby it is gravity fed. The chamber has opposite, parallel, fixed sides on all but the blade and exit sides. The exit side is completely closed in by a gate. Means are provided to move the blade from a first position below and to the outer side of the hopper to a second position towards the exit gate of the chamber when in compacting action, and from this second position back to first position when in recharge action. Further means are provided to pivot the blade from a transverse, fixed, vertically oriented position when in compacting action to a transverse, fixed, horizontally oriented position when in recharge action. The blade pivots from horizontal to vertical orientation as it begins its compacting action and pivots from vertical to horizontal orientation, to enable it to knife through fresh hopper snow during its recharge action. The blade repe…
