6 Claims.

This invention relates generally to tensioning devices and particularly to load binders or tension-pull loaders for use with a chain or similar means to bind a load of logs and the like.

An object of the invention is to provide an improved load binder by which a chain can be tightened on throw of the binders lever arm in either direction.

Another object of the invention is to provide an improved load binder in which certain of a plurality of relatively movable chain engaging hooks can be held against relative movement for locking the binder in load binding position.

Other objects and advantages of the invention will appear hereinafter in the detailed description, be particularly pointed out in the appended claims and illustrated in the accompanying drawings in which:

Figure 1 is a perspective view of a load binder embodying the present invention, the load binder being shown in open position and applied to the opposite ends of a load encircling chain,

Figure 2 is a side elevational view of the binder of Figure 1 in closed position with portions broken away, and

Figure 3 is a side elevational view of the lever of the binder with the hook attachments removed and part of the handle broken away, the lever being shown on an enlarged scale.

Referring now in detail to the drawings illustrating a preferred embodiment of the invention and in which like reference characters designate like parts, the improved load binder has a lever I0. Adjacent one end, the lever is offset and bifurcated to provide a pair of spaced arms I I, the outer ends of which are formed as a pair of aligned hooks I2. While the arms II may be spaced throughout their length, the upper edge of the lever preferably extends between and connects the arms almost to their hooked ends, thus forming a downwardly opening U-shaped bifurcation, slot or channel I3 defined in part by the arms.

On the offset portion of the lever, inwardly of its hooked end, are provided a pair of outwardly facing trunnions I4 through which the ends of a clevis or yoke I5 are pivotally connected to the lever. Intermediate the trunnions or pivot of the clevis and the hooked end I2 of the lever, with its inner end received or seated within the 2 slot I3, is an arm or linkage I6 which is pivotally attached to the lever through a pin I! or like means.

Adjacent their outer or free ends the clevis I5 and the arm I6 are provided with hooks I8 and I9, respectively. These hooks are preferably swivelly secured to their associated members, as 'by the swivelly mounted eyelets 20, and may be connected to the eyelets either directly or through links 2 I, depending upon the spread desired.

As shown in Figure 1, the clevis I5 and the arm I6 are preferably pierced adjacent their outer ends to provide openings or

holes

22 and 23, respectively. From Figure 2 it will be seen that these openings are positioned to align with corresponding openings in the lever when the load binder is completely closed. Of the latter openings, one may conveniently be that defined by the concave inner faces of the hooks I2 and the other an opening 24 piercing the arms II adjacent their inner ends. With this construction it is possible to lock either or both of the pivoted members I5 and I6 against pivotal movement relative to the lever by inserting a locking pin 25 through one or both of the sets of aligned openings one set being the opening 22 in the clevis and the inner faces of the hooks I2, and the other openings 23 in the arm and 24 in the lever. Such a locking pin may conveniently be formed of a cotter pin attached to the lever by a connecting chain 26 of convenient scope.

In binding together a load of logs and the like it is customary to'encircle the logs with a chain 21. After the logs have been so encircled the load binder is applied. In applying the binder, the hook I9 secured to the arm I6 is first engaged in a link in one of the free 'ends of the chain. As will 'be apparent, this hook remains in engagement with the chain and serves as the anchor for the binder throughout the subsequent operations or movements of the latter. With the binder in the open position of Figure 1, the chain is then stretched manually to the extent practicable and the hook I8 engaged in the nearest link in the other end of the chain. The lever III is then thrown or moved to the closed position illustrated in Figure 2, the inner ends of the clevis and arm, in process, reversing position. By this operation the slack in the chain 21 is reduced by substantially twice the spacing between the pivoted ends of the clevis and arm. At this stage the nearest link in the loose portion of the end of the chain engaged by the hook l8 secured to the clevis I5 is inserted sideways in the hooks I2 of the arms H and the next higher link in the chain slid edgewise in the space between the hooks. With one end of the chain 21 thus gripped by the hooks l2 and the other end still engaged by the hook l9 secured to the arm [6, the lever to is thrown or moved in the opposite direction until it again assumes the open position shown in Figure 1. In process the slack in the chain 21 is further reduced by substantially twice the distance between the pivot pin I! and the hooks l2. At the same time tension is shifted from the hook [8 on the clevis to the hooks l2 forming the hooked end of the lever, enabling the former to be disengaged from the chain. After the lever has again reached open position a second bite is taken on the chain by reengaging the hook [8 with the nearest link in the adjacent end ofthe chain and the lever is then thrown for a second time to closed position, releasing in process the hooks l2 and enabling them to take another bite on the chain after the lever has reached closed position. Thereafter these steps are repeated as often as necessary to eliminate slack from the chain 26 and bind the load tightly together.

The last throw of the lever in tightening the chain is preferably to closed position. At that point, the opposite ends of the chain are engaged by the hooks l8 and i9 and the clevis and arm are folded along the lever with the sets of locking pin receiving openings in the clevis i5, arm l5 and lever H) in alignment. A locking pin 25 is then inserted in one or both of the sets of openings to interlock the lever and one or both of the pivoted members against pivotal movement and thus lock the load binder in binding position.

To release the load the locking pin is removed and the lever arm thrown toward open position. As the lever approaches open position a link in the loose portion of the end of the chain engaged by the hook I8 is gripped by the hooks S2. The throw of the lever to open position is then completed relieving the hook I-B from tension and enabling it to be released. The lever is next thrown toward closed position with one end of 7 the chain engaged by the hooks 12, further slackening the chain. Before reaching closed position the hook i8 is reengaged and the throw then completed, thereby transferring the load from the hooks I2 to the hook I3 and enabling the former to be released. These operations are repeated in sequence until the tension on the chain has been released sufficiently to enable the load binder to be disengaged and the chain removed from the load.

From the foregoing detailed description of the invention it will be apparent that there has been provided an improved load binder of relatively simple and rugged construction which is capable of increasing the tension applied to chain on throw of its lever arm in either direction. Since one of the hooks, that carried by th arm l6, remains in engagement with the chain to which it is applied throughout both tensioning and releasing operations, the improved load binder is adaptable as well to the tightening of fences and like operations as to the tightening of a load binding chain. It should be understood that the described and disclosed embodiment is merely exemplary of the invention and that all modifications" are intended to be included which depart neither from the spirit of the invention nor the scope of the appended claims.
