APPARATUS FOR TRANSPORTING LOGS.

Application filed September 11, 1911. Serial No. 648,706.

' To all whom it may concern:

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 an apparatus for transporting logs.

The object of the invention is to provide means for quickly setting up the apparatus for operation, and providing simple, economical and convenient mechanism for effectually transporting logs from the point of felling of the trees to a point of storage.

The invention also comprehends improvements in 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 of my improved apparatus. Fig. 2 is a side elevation of the mast. Fig. 3 is an enlarged detail vertical section of the lower end of the mast, and its support. Fig. 4 is a detail horizontal section of the same. Fig. 5 is a detail enlarged section of the upper end of the mast.

1 indicates a car with which my improvement is preferably associated, although it is to be distinctly understood that a car is not absolutely essential in carrying out the invention.

Mounted on the car is a base 2, provided with an annular track 3, supporting a plurality of antifriction rollers 4. Fitting over the base 2, is a plate 5, provided on its underside with a track 6, with which the anti-friction rollers 4, engage. The plate 5, is held in relative position with the base 2, by an overhanging annular flange plate 7 the inner lip of which fits over the outer edge of said plate, as clearly shown in the drawings. Extending upwardly from the plate'5, are two ears 8-8, which are pivot-- ed at 99, to two outwardly projecting ears 10-10, on a base collar 11, secured to the bottom of a mast orspar 11 Projecting Specification of Letters Patent.

from the opposite side of the base collar 11, is a lug 12, which is engaged by a detachable overhanging fiange 13, bolted to a lug 14, extending up from the plate 5. The mast or spar 11 is rigidly secured in the base collar 11, and extends upwardly therefrom. The upper end of the mast 11*, receives a fixed cap 15 and riveted or otherwise secured thereto are two spaced apart side members 1616, forming a housing for a series of pulleys 17, 18 and 19. The middle pulley 18, is slightly higher than the pulleys 17 and 19, to cause the cable to more readily track in the grooves and to equalize the strain. Each member 16, comprises a side plate 20, and two angle irons 21, bolted to said plates to provide a substantial and rigid structure. Fitting on the upper surface of the two members 16, 16 is a plate 23, provided with a trunnion 24, on which is loosely mounted a flanged collar 25 for receiving the guy ropes 26. This construction provides a convenient and efficient swivel connection at the top of the mast, whereby the latter may be turned to suit the'location of the logs to be hauled. Near the bottom the mast is formed with a slot 27, in which are mounted two pulleys 28 and 29, over which pass the main cable 30.

Located on the car is a hoisting engine 31, of any convenient type, and surrounding said hoisting engine is a suitable frame 32.

The mast is raised in a vertical position as shown in Fig. 1, and the main cable, is unwound from the main drum 33. The cable passes around a guide pulley 34 located under the base 2, and extends up through an opening 36, in the latter, and also through an opening 37, in the plate 5, and an opening 39 in the bottom of the mast, said latter opening communicating with the slot 27. The cable now passes over the rear of pulley 28, and thence over the front of pulley 27 and up the outside of the mast and around a pulley 40, swiveled to a ring 41, on said mast. The ring 41, is suitably braced, as by a guy cable 43, shown in Fig. 2. The main cable, after passing around the pulley 40, is passed around a pulley 44, swiveled to a tree stump, or other convenient support adjacent the car. The rope then passes over the pulleys 17, 18 and 19, and its end is securely fastened to a post or other support 45 in line with the logs to be transported toward the car. The main cable supports a carriage 46, having guide rollers which travel on said cable. The carriage is fastened to one end of a receding cable 47, which passes over a swiveled pulley -18, secured to the post 45. The receding cable then passes between two guide rollers -19, on the side of the carriage and then over a swiveled pulley 50 on the mast, and thence to one of the drums 51, of the hoisting eng The hoisting cable 53 passes over a pulley swiveled to the bottom of the carriage, and thence passes over a swiveled pulley 54, on the mast, and then to one of the drums 55 of the hoisting engine. Swiveled to the hoisting cable at 56 is a slack pulling cable 57, which passes over a guide pulley 58, within the carriage and is thence guided over a swiveled pulley 59, to one of the drums 60, of the hoisting engine.

In operation, the car is transported to the appropriate location, and the mast is raised and the parts connected as described. The cable 17, is drawn to bring the carriage adjacent the logs to be moved, then the hoisting rope 53 is slackenecl, and the slackening rope is wound on its drum until the end of the hoisting rope is in convenient reach of the logs. The logs are fastened, and the hoisting drum is operated to raise the logs the desired height, then the slack rope 57 is freed, the receiving rope is slackened and the hoisting rope is wound on its drum.

, Then when the log reaches the desired point,

it is lowered and released.

By my novel arrangement of parts, the main cable can be quickly and conveniently attached to any post or tree within a radius of the operating plant, the cable being stored on the drum to be fed out as circumstances may require. The arrangement of the mast is such as will accommodate the adjusting and placement of the cables, so that a wide field of timber land may be cleared by one setting of the car and its mast.

To transport the apparatus, guy wires are removed and the flange 13, is also removed, and the mast is rocked on the pivots 9 9. as shown in dotted lines in Fig. 1.

To elevate the mast, I provide a standard 65, on the end of the car, and secure thereto a pulley 66. The hoisting cable is now passed over a guide pulley 67, thence over the pulley 66, and is attached to a ring 66, on the mast. Now by operating the drum the mast may be raised to its vertical position.
