LOGGING-TACKLE Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed June 27, 1908. Serial No. 440,748.

To all whom it may concern:

Be it known that I, CORNELIUS TURPIN, a citizen of the United States, and a resident of Scappoose, in the county of Columbia and State of Oregon, have invented a certain new and useful Improvement in Logging- Tackle, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention has for its object to so arrange the tackle employed for hauling logs as to obtain a straight line or direct pull in the direction of the engine, and without '5, interruption of the hauling; and to this end my invention consists of the features and combination of parts hereinafter fully described and claimed.

In the drawings: Figure 1 is a diagrammatic plan of my logging tackle; and Figs. 2 and 3 are, respectively, a partial plan and sectional side-elevation of a type of block which is necessarily usedin connection with my tackle, as hereinafter fully explained.

Referring now to the letters in the several views: (4 represents the usual donkey-engine, provided with a drum Z), on which winds the main line or cable 0, a drum (Z, on which winds the chaser line or cable 6, and a drum 0 f, on which winds the haul-back cable 9. The drums 6, (Z, f, are provided with the usual working appliances and arranged, operated .and controlled as usual.

At 71 is provided a fixed or stationary i5 block for the chaser line 0, and at is provided a fixed or stationary block for the haul-back cable 9, and to the outer end 6 of the chaser line 6 is secured a movable block h. A detail of construction of the block h to is shown in Figs. 2 and 3. Its construction is necessarily such that it is balanced on the main line passing around the sheave 76; for the construction and suspension of this block h must be so contrived that when the pull on i5 the chaser line 0 is released, the sheave-end of the block 72, will not over-balance its swivel-end Z, and thus cause the block to hang from the main line, since such position of the block would have a tendency to cause the same to foul with the main line. To this end the block b is provided with a weighted section m, intermediate its extremities. In other respects the block h, as shown, comprises a pin a, connecting the swivel; the pin n being secured in place by a split-key n.

The cheek, or side-piece section, o,has a lipsegment 7), engaging with a corresponding lip-segment g on the short side-piece IL of the block. \Vhen the piece 0 is turned to one side it leaves an upper opening for the insertion of the main line 0 around the sheave la. Said opei'iing-piece 0 is secured in place by a set-screw r, or other convenient means. At the throat of the block, the weighted section m is cut away, so as to pro- 6 5 vide an entrance, as shown in Fig. 3; and on the bottom of the opening-piece 0 is provided a protuberance or rib s, filling in said throat opening when the movable-part 0 is closed; and thereby so arranging the parts 7 that the main line 0 is confined in place on the sheave k.

t, 16 represent blocks arranged to guide the haul-back cable.

Hy tackle operates as follows: Supposing a to represent a log, and u, a successive positions during its hauling by the donkeyengine, when the work of hauling a log from a distance towards the loading platform (supposed to be located at some convenient point between the donkey-engine and the system of blocks h, 2', j) is commenced, the drum (Z will have been operated so as to pull the block h to the position thereof shown in solid outline in Fig. 1, the drum 6 having been released so as to enable the haul-back cable 9 to pull the end of the main line to the log.

Supposing that Fig. 1 illustrates diagrammatically the respective cables being operated to haul a log towards the loading platform, the solid outlines of the parts show that there would be a direct pull by the engine towards the block h. WVhen the log has been brought into proximity with the block h, the brake on the drum cl, of the chaser line, is released, so as to allow said line to play out, and the block it to follow the pulling movement of the main line 0. The movements of the parts during these operations are apparent by observing the positions of the log and tackle connections, as shown in dotted outline at u and 10 The chaser line need never be unhooked from the log, for when the latter has been hauled to the loading platform, the drum 6 of the main line is released, the haul-back cable operated to pull the end of the main line back to the next log to be hauled, and the drum (Z is operated simultaneously to cause the chaser line 6 to pull the block it back to its initial position, as shown in solid outline in Fig. 1.

To distinguish my invention from the tackle now commonly used, I might say that the general custom heretofore was, to have only a main or hauling line, a lead block corresponding in position with the block 1:, and a haul-back line running over blocks corresponding in position to the blocks j, t, t; the main line running over the lead block 2'. The log was hauled to the lead block, and the choker 0 and butt-chain pulled one-half way through the lead block. The choker and butt-chain were then unfastened, taken out of the lead block, and again hitched to the main line for pulling the log to the loading platform or roll way, all such operations taking considerable time, and interrupting the hauling work. Sometimes there is used a lead-block having an open side, so that instead of proceeding as described, the main line would merely be slackened, and lifted out of the lead-block. But this method took considerable time too, and required means to pull the main line back into position to be reinserted in the lead-block. Furthermore, the earth around the lead-block is usually pretty much clawed up and a hollow place formed, filling with water and rendering the work of the man, there stationed, very hard and disagreeable.

In my arrangement no man is required at the lead-block, for no attention to the leadblock is required. The work of hauling the log from the head block (t, t) to the roll way is continuous, thereby saving also the loss of time occasioned by the interruption of the work under the old method.

I claim:

1. In a logging tackle, the combination of a hauling engine, and drums thereon, a main line, a choker, a haul-back line, guide-blocks for said line, a chaser line, a guide block over which the chaser line runs, a movable block attached to the end of the chaser line, said main line running on said movable block, and said movable block being weighted so as to fulcrum and rest in substantially horizontal position on the main line when the pull on the chaser line is released.

2. In a logging tackle, the combination of a hauling engine, and drums thereon, a main line, a choker, a haul-back line, guide-blocks for said line, a chaser line, a guide-block over which the chaser line runs, a movable block attached to the end of the chaser line, said main line running on said movable block, and means arranged to prevent the fouling of said movable block with the main line when the pull on the chaser line is released.

CORNELIUS TURPIN.
