HIGH-LINE CARRIAGE.

Application filed October 19, 1927. Serial No. 227,211.

The present invention relates to a high line carriage particularly adapted for hauling logs, and has for its prime object to provide a structure wherein it is possible to hoist a log to any convenient height, and haul the same safely without injury to any surrounding timber and the like. In the old method of hauling in logs by the high line, the logs moved towards their destination before they had cleared the ground, causing much breakage and the loss of small trees by the logs dragging over them. The present invention overcomes these undesirable features.

A still further important object of the invention resides in the provision of carriage of this nature which is simple in its construction, inexpensive to manufacture. Strong and durable, thoroughly eflicient and reliable in operation, and otherwise well adapted for the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of the carriage embodying the features of my invention.

Figure 2 is a top plan View thereof.

Figure 3 isa vertical transverse section taken substantially on the line 3 3 of Figure 1.

Figure 4 is a vertical longitudinal section taken substantially on the line 44 of Fig- Y will be seen that three plates, 5,6 `and 7 are held together in spaced parallel planes by suitable bolts-8 or other fastening elements. A pair of grooved rollers l Vand plate 6. These grooved rollers 10 and 11 are adapted to ride on the high line 16. A grooved roller 17 is journaled on the shaft 18 between plates 5 and6 below the grooved roller 1() and has trained thereover a pull and hoist line 19 which isl trained under the pulley of the hoisting block 20 and is anchored as at 21 in an arm 22 which is pivoted as at 23. A clutch structure denoted generally by the letter C comprises a plurality of blocks 24 with notches 25 therein through which is trained the high line 16 between the rollers 10 and 11. These blocks are connected together` at their upper and lower ends respectively by

bars

27 and 28. One of the end blocks 24 has an extension 29 with a slot 30 formed therein. The bar 28 is extended at the end opposite to the block 24 having the extension 29. The extremity of the extended portion of the'bar 28 is pivotcd as at 31 to the arm 22. A pin 33 between the plates 5 and 6 extends through the slot 30. A shoulder 34 is mounted between the plates 5 and 6 and has a recess 35 in the lower portion thereof to receive the upper end of the block 20. Guides 36 are provided to lead the block so that the upper end will seat in the recess 35. A projection 37 is provided on the upper ends of the block laterally thereof and moves in a vertical slot 38 provided in the plate 6 extending vertically from the lower edgey thereof. A pair of spaced parallel guides 39 are mounted on the plate 6 one to each side of the upper portion of the slot 38. A second pair of guides 40 are disposed in spaced parallelism onthe plate 6 above the guides 39. These

guides

39 and 40 are vseparated by a slot 41 in the plate extending horizontally.

A Z-shaped member 42 is movable between the

Guides

39 and 40. A pair of pins 43 ant 44 project vlaterally from the lower portion ofthe clutch structure C as is shown to advantage in Figures 3 and 4 and projects through the slot 41 to be disposed one on each side .of the Z-shaped member 42. The weight of4 this Z-shaped member 42 is sufficient so that its intermediate portion would .function as a cam lll) when the Z-shaped member gravitates downwardly and moves the bar 28 to pivot the blocks 24 to their locking position as shown in Figure 8. The block with its projection 37, however, holds the Z-shaped bar 42 in a raised position when the block is raised. However, as soon as the block lowers, the Z-shaped member tends to immediately lock the clutch on the high line 16 so as to prevent any movement of the carriage. It will also be seen that as the block 20 moves down to the dotted line position shown in Figure 5, the cable 19 will pass over the pivot 23 so as to tend to swing the arm 22 to the dotted line position shown in Fig. 5 and further assist in the locking of the clutch structure.

A latch is pivoted on a pin 51. This latch 50 has pivoted

extensions

52 and 53 at its ends. The extension 53 is in the downward path oi' the projection 37 so that in order for the block to lower, it will be necessaryr 'lor the latch 50 to swing to the dotted line position shown in Figure 4. This latch is prevented from swinging to this position by means of a bolt 54 slidable in a way 55. This bolt is slidable by one end of a lever 56 projecting thereinto being pivoted as at 57 and having its upper eittremity engaged with the pins of the pin wheel 14. Springs 58 tend to hold the lever in a vertical position.

A lin'e 59 is attached to a block 2O so as to return the carriage to the position for engaging the logs. `When in the proper position, the cable 19 is slackened thereby allowing the block 24 and simultaneously allowing the Z-shaped bar 42 to p ull so that the pinv 44 will tend to lock the clutch and simultaneously the slackening of the cable will allow the.arm 22 to swing over to the dotted line position to which it is urged by the clutch thereby assuring the locking of the clutch.

New the movement of the carriage by the cable 59 rotates the pin wheel 14, in Figure 4, in a counter-clockwise direction so that thebolt 52 is slid out of the way of the latch extension 52 soA that the latch 50 may fit into the dotted line position and allow the block to move downwardly. When the block is down, and the log is engaged thereon by means of a chain or in any other desired manner, the. cable 19 is pulled by a winch or Yother structure so as to hoist the block 20.

As the block moves upwardly into the guides 32 and finally comes vto rest in the shoulder 34 the further pulling of the cable 19 will eausethe swinging of the arm 22 to its full line position thereby releasing the clutch and simultaneously, the projection 37 will engage the Z-bar 42 so that the intermediate portion thereof will function as an inclined plane or cam on the pin 42 and will unlock the clutch.

The further pull on the cable 19 will pull the carriage to the left as shown in these drawings which rotates the pin wheel in a clockwise direction so that the bolt 54 is eX- tended over the latch extension 52 so that the block cannot fall as long as the carriage is moved in this direction.

It is thought that the construction, operation, utility, and advantages of this invention will now be quite apparent to those skilled in this art withouta more detailed description thereof. The present embodiment of the invention has been disclosed in detail merelyby way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
