Our invention relates toimprovements in aerial hoisting and'hauling apparatus of the form commonly known -,-.-as I Canyon skid- 'ders, which "apparatus embodies" a -main track cable, a carriage movable thereon, and

a plurality of operating'or control cables for moving the carriage and hoisting and haul:

The apparatus hereinafter described defsigned for use inconnection with logging operat1ons 1n canyons or deep ravlnesfwhere long and heavy cables are required to I drop down from suspended carriagetoa load that is to be picked up 'or moved, but it will;

be understood that' said-app'aratus may be employed in all other industries: Where similarconditionsiprevail. 1, V

The object of our invention is to provide simple and efficient means tor -controlling the lowering of that: portion :Of 'afcable or skidding line known as the tong line,.which tong line runs over a sheave. or drum in the from for a comparatively long. distance to the load that istobe hoistedor moved, J

'-More specifically stated, the object of our invention is to provide means for lowering 'or overhauling the tong'line by establishing a drivingi connectio'n between the carriage sheave or drum over which saidtong linepasses and another line einbodied in the'apparatus and known 'astheslack pulling line, and which-is used for slacking the tong line or drawing the same back toward: the

carriage.

In hauling and I type, heretofore used-,iand' whichrdoes'not embody our invention, it has been found to be impossible'to get a long tong line tov run ,backover the carriagesheave or drums with- 7' out attaching needless weight'to-theendof said tong line, It has' also been found that a short tong line or alon'ger tong linethat is weighted will not always-run back at a constant velocity but will sometimes hang line.

by the arrows inFig. 5.

In Figs. 6 and 7 the slack pulling line is shown as passing from the Shay swivel over a slack pullingline sheave thence down and around a driving sheave 36 that isrigid with the tong line drum, thence directly out to the means, not shown, by which it is wound passes from theShay swivelover a sheave 37. thence down and around a driving sheave 38,

which'is connected with the tong line drum,

thence up over an idler sheave-39, and thence outwardly to its source of power, thereby -affording means for driving the tong line drum r and controlling the lowering the tong line. 1 V

In Figs. 11 and 12 we show a modified form of carriage in which the tong line drum- 40 and the driving drums or sheaves 4:1 therefor are located in a separate" b'lock42 thatisflexibly connected by means 43 with a main carriage body 44:. In this device the slack its source of power.

pulling line extends from-the Shay. swivel, over a sheave 45 in the. carriage 44:, thence wardly over another idler sheave 47in the main 'carriageet and thence. o

' utwardly to In Fig. 13 we show a carriage in which the tong line drum 48 is driven by a train-of gears 49, 50and 51 that connect with the slack pulling line sheave 52; e

In some instances wide sheaves or drums are shown and the cables wrapped one or more timesaround the same to secure the necessary traction for driving. In other instances sheaves with convergent or 'V shaped peripheral grooves are shown for frictionally gripping and driving the cables, the two 2 forms being generally interchangeable asdesired.

Obviously, changes maybe made in the forms, dimensions, and arrangement of the parts of our invention, without departing from the principle thereof, the above setting forth only a preferred form of embodiment.
