APPARATUS FOR TRANSPORTING LOGS.

Specification of Letters Patent.

Patented July 1, 1913.

Application filed April 12, 1912. Serial No. 690,457.

To all whom it may concern Be it known that I, FREDERICK W. Vinn- ING, citizen of the United States, residing at Davis, in the county of Tucker and State of West Virginia, have invented certain new and useful Improvements in Apparatus for Transporting Logs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in means for transporting logs.

In my prior Patent, No. 1,015,103, dated January 16, 1912, I illustrated and described a mast provided with a cap constructed in such manner as to necessitate the main cable being passed over a guide pulley attached to a support located to one side of the apparatus. My present invention is primarily designed to avoid this contingency, and the improvement is directed to the features which will permit of the main cable passing direct from the housing at the top of the mast to the guide pulleys in the lower portion of the mast and thence to the operating drum. v

My invention also comprehends improvements in the means employed for bracing the mast in opposition to load strain when hauling logs.

The invention also relates to the specific details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation illustrating the application of my invention. Fig. 2 is an enlarged elevation of the mast, parts being shown in section. Fig. 3 is a detail plan view of the mast cap. Fig. 4 is an end elevation of the same. Fig. 5 is a diagrammatic perspective view of the arrangement of the blocks and the bracing cable adjacent the top of the mast.

1 indicates a car, supported on wheels 2, and adapted to travelon the track 3. On the car is a base 4, comprising a lower stationary section 5, preferably supported on sills, and a rotatable upper section 6, having hinged at 7 amastsocket 8, locked in position by a latch 9.

Fitted in the mast socket is a mast 10, formed at its lower end with a vertical opening 11, the upper portion of which merges into an open slot 12. guide rollers 14:, over which a main or cable track 25 passes, and below the opening, and suitably supported below the lower station ary section 5 is a guide roller 15.

On the upper end of the mast 10, is secured a cap 16, formed with a flange 17 on which are bolted two parallel vertically disposed spaced plates 18, between which a series of rollers 19 are mounted. To the upper ends of the plates 18, is bolted a tip 21, having a trunnion 21 which receives a support 21 for the upper ends of guys 22. The lower ends of the guys 22 are staked or otherwise anchored to hold the maststeady when the apparatus is set up for op eration. Each roller 19, is mounted in a different vertical and horizontal plane than the adjacent roller to form a gradual curved track for the main cable, the periphery of the lowest of said rollers being slightly beyond the plane of the outer surface of the mast, as clearly shown in Fig. 2.

The inner end of the main or cable track 25, is wound on a drum 26, from whence itpasses over the guide pulley 15, and thence through the vertical opening 11, and over the guide pulleys l4, and up along the outer surface of the mast to the rollers 19. From the rollers 19, the main cable extends above the plane of the forest being worked, and is secured to a stump or tree as indicated at 30.

Mounted to travel on the main or cable track 25, is a carriage 31, which is operated from the car, in substantially the same manner, shown and described in the beforementioned patent.

In the slot 12, are two The cap 16 is provided with a lateral eye 33, which supports a block 3 1, including two pulleys 34 and 34-." around which the cable 35 passes. The cable 35 comes from a drum 36, and is guided under a pulley 37 on the.

mast, and thence around a pulley 35 swiveled to the mast below the block 34:. From pulley 35*, the cable 35 passes around pulley 34, thence around pulley 38 mounted in a block 33, thence around pulley 34:", in block 34, and its free end is fastened to an eye 38 on block 38. Block 38, is secured to guy cables 41, the ends of which are anchored to supports or stumps of trees as indicated at 42.

In operation, the carriage 31, is drawn out on the cable track by operating the drums, and the hoisting cable is lowered and the logs are secured. hen the logs are elevated great strain is placed on the cable track, which has a tendency to pull the top of the mast in direction of the load. As the logs are drawn up toward the carriage, the drum 26 is rotated to take up as much slack as possible on the, cable track, which materially increases the pull on the upper end of the mast. To overcome this tremendous pull at the top of the mast, it is of the utmost importance that powerful means be provided to counter-act the tendency to draw the mast down. Hence, it is essential that the bracing cable be under such perfect control to regulate its tension to accommodate difierent loads when hauling toward the mast. Now, when a load is raised, the drum 36 is rotated, and because of the arrangement of the bracing cable, and its connections between the upper end of the mast and the guys 41, the mast is braced in opposition to the load strain exerted by the load on the cable track. Therefore the pull on the mast by the bracing cable can be regulated according to the load pull on the opposite side of the mast, during any period of the operation of hauling logs, which is ,of considerable importance, in that it insures stability of the parts, and permits of a ready means for releasing the strain on the cables when the apparatus is not in use.

The cable 35, performs a dual function. It acts as a brace to resist the strain, due to the weight of the logs being hauled, and it acts as a means for moving the car on the track to change the position of the apparatus. If it be desired to move the car, the carriage operating cables, and the main cable are slackened, and the operating drum 36 is rotated to wind the cable 35. The winding of the cable 35, will advance the car on the track to the desired position, and then by tightening the previously released cables, the cable 35 again becomes a brace for the mast.

I have found by practical experience the construction and arrangement of parts described enables me to perform the operation of hauling logs with a great deal of expedition, and with greater degree of surety of bracing and steadying the parts. I am also enabled to quickly shift the guy cables 22, and the main cable 25, and turn the mast and operate over an area disposed at various angles from the car. By placing cable 25, as shown and described, I am enabled to change the position of the cable with considerably less trouble and expense, and can at the same time remove logs from a much larger area than is possible with apparatuses now in use.
