To all whom it may concern Be it known that I, WILLIAM Gonrnr., a citizen of the United States, residing at Stevenson, in the county of Skamania and State of Washington, have invented a certain new and useful Improvement in Cable- Grips, of which the following is a full, clear, and exact description.

Thelobject of this invention is to provide a so-called grip or clamping device, by which a load, Vsuoli as a log, to be conveyed from one'place to another, may be conveniently connected toa traveling cable or conveyer so as to be thus transported, and may, with equal convenience, be disconnected from the cable as occasion may require. Various systems of arranging vsuch cables or conveyers are in use, in some of which the main line cable runs from the forest where logs are obtained, down-hill or otherwise, to the place where the logs are to be delivered, to a donkey-engine or other power aPP cable, the latter 'is and with it the log, and when the log is delivered it is disconnected from the cable and the latter hauled backby a haul-line to the Starting point for another log. In some cases endless cables are used. The cables orconveyers are arranged ,overhead so as to make sure of their clearing `stumps of trees and other obstructions. A common practice is to have a `main line extending some distance into the woods or forest, and

provided with butt-chains on its ends and a trip-line or haul-back which is used'to haul the main line back into the woods after it has been used to drag a log out of the woods.

In accordance with this practice, only one 40 log, or, at most, tw logs can be dragged out at a time, and thus the expense of oper-` -ating is high.

The present invention is designed to admit of dragging out a largenumber of logs at once, without danger of kinking or crushing the line, and in such way that the logs may be applied to the lline or taken off of itat any time or place and without stopping the line, the greater pull on the 'connecting device or grip serving to strengthen its liol on the cable or conveyer. But the present invention is not confined in use to any ,par-

.ticular system of cable or conveyer, nor is it restricted to use in logging, as it may be advantageously used as a grip 1n cable' sysliance, and a lo being connected to the rawn toward the enginel y grooves may `engaging element, and a complementary movable element, this movable element being operated by a trigger which may be connected wth .a clevis pivoted to the grip and to which 'the load is applied and which otherwise is wholly independent of the movable element, said trigger capable of independent operation so as to attach the grip to the cable and disconnect it therefrom at pleasure, as I will proceed now more particularly to explain and nally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a perspective View of the grip, partly open.` Fig. 2 is a side elevation, partly invertical section and broken away to expose the interior, the full lines showin the grip closed upon a cable and the dotte lines showing it released. Fig. 3 is an elevation looking at Fig. 2 from the left-hand side. `Fig. 4; is aside elevation, in gripping position, v with the clevis and trigger connected as shown by full lines, and disconnected as shown by the dotted line link at the free end of the clevis. Fig. 5 is a sketch of a conventional arrangement of logging cable, (proportions being disregarded) in which the log is shown as chained to the trigger instead of to the clevis.

The grip comprises a casing 1 of any suitable construction, -provided with a side opening 2 by which it may be applied to a cable or conveyor, and having on a stationa ary or fixed part a cable-engaging groove 3 extendingV fore and aft. Below this groove isl an interior cavity 4 in which is arranged a sliding wedgeshapedblock 5, provided with a eompleinental fore and aft groove 6 to cooperate with the groove 3 in engaging the cable or'conveyer. These be roughened or otherwise prepared to increase the hold on the cable. The block 54 is engaged with the opposite sides of the casing so as to be guided in its fore land aft'movements therein, and as one suitable means to this end2 have shown the sides provided with inclined tongues 7 `which engage corresponding grooves 8 in ioo vof-a link 14 with a clevis l5, which last is pivoted at 16 to the 'sides of the-.casing and .has an eye 17 by which one-end of a chain 18, may be applied to it, the 'other end of the chain being adapted to beapplied to the log or other load to be transported. The link 14 may be detachably connected with the trigger or hook 13 by means of a spring pin or other movable device 19.

The grip or clamping device is `opened as shown in Fig. 1, and applied laterally to the cable or other conveyer"20,.as indicated in Fig. 2, and then by a movement of the trigger-toward the right, or in opposition to the direction of. travel of the cable,.the

block 5 is moved toward the cable and the cable clamped between the block and the portion of the casing containing the groove 3.' This movement of the trigger may be effected by the strain placed upon the clevis causing the clevis to move toward the cable andthe link 14=transmitting this motion to the trigger. The trigger has an eye'21 to which a trip-line may be applied so as to reverse the motion of the block and edect thedisengagement of the grip with the cable whenever desired and whether the cable is taut or slack.b In some instances the load may be applied to the trigger itself by connecting it with the eye 21 of the trigger, and Such an `arrangement is indicated' in Fig. 5 where as shown, the link` 14 is disconnected from the trigger. and the-clevis left unused.

With the grip of this invention it is possible to apply as many logs or other loads along the cable. as there are available grips, instead of limiting the use of the cable, as in some present arrangements, to one vor two logs or loads. This grip will not crush or kink the cable, and may be applied to or v taken off of the cable at any place and even while strain is on the line; and the greater the pull on the cable the-'stronger is the hold of the grip on the cable. As long, as there is a pull on the cable toward the power or rollway, the grip will remain tight, and as soon as there is a slack up in lorder to haul the cable back, the load remains where it l was le'ft and is again "taken u p when the pull is once again started ahead.

As already sufficiently indicated, the invention is applicable to cable or conveyer arrangements for transporting logs and other loads; and it is to be understood also thatyariations in details of construction are permissible within the principle of the invention as herein` claimed. .And yin this connection it is to be noted that the clevis is not applied to either clamping element in itself considered, but to the casing containing the clamping elements, and that the active clamping element is controllable independently of the clevis.
