To all iv/1cm it may concern: 3
Be 1t known that I, FRANK M. SHAW, a citizen of the United States, resldlng at Edgewick, in the county of King and State of Washington, have invented new and useful Improvements in Logging Systems, of which the following is a specification.
This invention relates to logging systems and consists in certain improvements in the construction thereof as will be hereinafter fully described and set forth in the claims.
The object of the invention is to provide a cable system of logging which is simple and efficient.
The invention is illustrated in the accompanying drawings as follows Figure 1 shows a perspective view of the system on slanting ground. Fig. 2 a plan view of a stop andcatch forming part of the mechanism. Fig. 3 a side elevation of the same parts and a cable carriage engaged by the catch. Fig. a a view of the log attaching means. Fig. 5 a perspective view of the system arranged on level ground.
1 marks the overhead line. This is supported at the yard end by the head tree 2 and at the outer end by the tree 3. The line is run through the blocks 1 and 7 on the trees 2 and 3 respectively and is secured in any suitable anchorage (not shown). The trees are guyed by the stays 8 in the usual manner. The haul-in line extends from the drum 10 on the engine 11 through the pulley l2, pulley 13, pulley 14 on the carriage 1% back to the block 13. The carriage 14L is free to travel on the overhead line 1. The log attaching means 15 are of any usual construction and are secured to the block 13. One type is shown in Fig. 41: and in Figs. 1 and 5 this means is shown attached to a log 16.
In pulling in the log through the action of the haul-in line, the log is partly lifted and partly dragged, that is to say, the part of the line running to the carriage tends to lift the log and the part of the line running to the engine tends to pull the log in. The result is that where the log encounters an obstruction as indicated by the stump 17 the continued pulling on the line lifts it over the stump and it then swings forward to the ground. The carriage follows the log.
The haul-back line 18 extends from the block 13 through the pulleys 19, 20 and 21 to the drum 22 on the engine. The pulleys l9 and 20 are arranged on stumps 23 and 2% respectively. The pulley-19 particularly is changed to adapt the haul-back line to return the log actuating devices to a position to readily fasten the log attaching means to a log. It is, therefore, usually offset from the overhead line so that the log at the side of the overhead line may be reached. Quite a large area each side of the overhead line can in this way be covered without changing the overhead line. By securing the haulbacl: line to the fall block 13 or to the log carrying means adjacent to the block 13 a resistance may be put upon the movement of the fall block 13 and when this is done and the movement of the haul-in line is continued the fall block is lifted and in this way the log may be carried over obstructrons.
Where the overhead line is on slanting ground a stop should be provided to limit the movement of the carriage. I provide the stop 25 at the lower end of the line. This is in the form of a pulley block on the line and is controlled by an anchor line 26 which as shown is secured to a stump 27. The stop 25 can be changed from the ground by means of the line 26.
I provide the stop 28 at the upper end of the line. It is in the form of a pulley block and is held in place by an anchor line 29. The line 29 extends through a block 30 in the head tree 2 and is secured to a stump 31.
The block 28 runs down the overhead line to the point desired by gravity and is secured in position by the line 29. A catch 32 is arranged on the stop 28 and is adapted to engage the shoulder 33 on the carriage and thus locks the carriage next the stop 28 while the line is slacked off to release the log. The catch is tripped by the trip rope 34:.
It is desirable to run the haul-in line through an overhead pulley as 12 as the logs may be more easily handled in piling them. W hen used on level ground as in Fig. 5 the stops will not usually be required. On some kinds of ground also the haul-in line can run direct from the carriage through the block 13 as in Fig. 5.
\Vhat I claim as new is 1. In a logging system, the combination of an overhead line; a carriage on the overhead line adapted to travel thereon; a load carrying means comprising a fall block; a line actuating mechanism; a haul-in line extending from the carriage through the fall block and thence independently ofthe carriage t0 the line actuating mechanism; a
haul-back line secured to said means and ing means comprising a fall block; a line actuating mechanism; a haul-1n line extending from the carriage through the fall block and thence independently of the carriage to the line actuating mechanism; a haul-back line secured to said meansand opposed to the haul-in line at the fall'block; and a guide pulley for vthe haul-back lineofi'set 15 laterally from the overhead line.
