An intermediate supporting device for a logging cable for supporting the cable above ground at an intermediate location. The device is arranged to permit a logging carriage to travel past the intermediate location substantially without being obstructed by the device. The device consists of a supporting sheave assembly supported on a transverse line extending between two intermediate spars or spar trees. A first horizontal shaft is swivelly connected to the lower end of the sheave assembly. A normally vertical link bar is pivotally connected at its top end to the first shaft and is pivotally connected at its bottom end to a second horizontal shaft which is parallel to the first shaft. Rigidly secured perpendicularly to the second shaft beneath the supporting sheave assembly is a support body member having spaced transverse vertical flanges with horizontally aligned peripherally grooved pulleys journalled therebetween, the flanges having holes to receive a haulback line engaged in the grooves of the pulleys. Rigidly mounted on the flanges above the pulleys is a rail member with inclined ends to serve as a guide support for the upper grooved pulleys of an open-sided logging carriage, permitting the carriage to travel smoothly past the intermediate supporting device.
In a skyline cable system of the type including a load-supporting cable and a load carrying carriage having an open side and having supporting pulley means engaged on said cable, an intermediate supporting assembly comprising intermediate spar means provided with attachment means overlying an intermediate portion of said cable, suspension means supportingly engaged with said attachment means, support body means located below and substantially in vertical alignment with said suspension means, guide means on the support body means slidably and retentively receiving the load-supporting cable, elongated rail means rigidly connected to said support body means and spaced above and extending substantially parallel to said cable and being formed to engage with and elevate the carriage off of said cable as the carriage moves past said intermediate supporting assembly on said rail means, and said rail means being formed with a top surface simulating said cable, whereby the rail means serves the function of said cable and directly supports said carriage when said carriage passes said intermediate supporting assembly, and whereby said guide means causes said cable to pass smoothly over said intermediate supporting assembly.
