With dished or an ed o er t roller un i the type of machine now in use, the height to loosely on asuitable axle such as a bolt 35 mount- 50 which goods may be stacked or piled is limited ed in the boom members ll.

During use the sling rope manipulation or stopping of the cable, thereby 65 drawing the upper part of the sling rope also over the roller 34, and correspondingly increasing the lift of the merchandise. As shown, a hook 36 is formed of smooth contour and having an eye 31 for flexible attachment to the cable and a hook 38 for receiving and supporting the sling rope ring or the like.

In operation, the cable 29 is paid out, the hook 38 is hooked into the sling containing the merchandise, and the cable is then wound until the sling is free of the ground and the machine may ybe driven and directed to the point of delivery for the goods. At a point of delivery, the pile of goods increases in height with the deposit there'- on of successive loads. To effect the piling, the load is elevated above theltop of the pile, and the machine moves it inand the new load is thus deposited on top of the pile or stack. With the increase in the height of the pile, my machine winds in the cable and pulls not only the cable, but the upper part of the sling. rope over the roller 34, and. thus the goods in the sling may be lifted almost to the height of the roller 34. The greater height of the roller 34 in my machine over that of the block hook plus the upper part of the sling rope of the ordinary machine represents the greater stacking efliciency of my machine. Thus the goods may be stacked or piledpractically as high as the roller 34 without any troublesome or laborious extra handling or lifting of the goods at the top of the pile, and as' the top of the boom usually represents the limit to which merchandise may be stacked, the machine is capacitated to directly deliver goods to the, highest level practicable in the dock or warehouse without additional labor.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the in vention and without sacrificing its chief advantages.

What I claim is:-

1. In a mobile stacking device a supporting frame, a boom projecting upwardly and outwardly therefrom substantially beyond said frame, a wide sheave journaled at the upper end of the boom, a cable running over the sheave and means attached to the end of the cable for receiving and supporting a sling rope, said means being capable of passing over the sheave and of drawing the upper portionof a sling rope over the sheave whereby a conveyed package may be lifted and stacked near the level of the sheave irrespective of the length or stretch of a sling rope.

2. In a mobile stacking device, asupporting frame, a boom projecting upward and outward therefrom substantially beyond said frame, a wide sheave journaled at the upper end of the boom, a cable running over the sheave, a sling rope, and means flexibly attached to the end of the cable for receiving and supporting the sling rope, said means being suificiently narrow and flexibly attached to the cable and sling rope to pass readily over the sheave and to draw the upper portion of the sling. rope over the sheave whereby a conveyed package may be lifted and stacked near the level of the sheave irrespective of the length or stretch of the Sling rope.
