In this condition when the rope poses, for which use itis especially designed, is caused to travel toward the left in Fig. mo

A spring h is connected with the cam-dog H, so as normally to draw it into its locking position with a slight pressure sufficient to cause its prompt engagement with the rope. The block H would ordinarily be placed below the wheels 9 enough to prevent the hoistingrope from engaging therewith when running out or when the dog H is out of use.

Upon the outer surfaces of the two frameplates of the grip G and at their edges, which are toward the head-support, are placed two flanges I, which are adapted to be engaged by the grip-locking mechanism carried upon the trip, which trip is supported on or near the head-support. The grip outhaul-rope (J is connected to the grip, as shown in Fig. 2. This grip onthaul-rope passes first to the carriage E and then backward toward the headsupport to its engagement with the grip G. Upon one side of the grip a curved bar I is shown, which. forms a guide to retain the carriage outhaul-rope C in place and prevent its becoming entangled.

The mechanism for tripping and holding the grip is shown in Figs. 4 and 5. The hoisting-cable 0 passes over the pulley b of a sheave-block B, which is supported upon the head-support. The trip which provides for releasing the grip from the hoisting-cable is herein shown as connected with the sheaveblock 13, although it is evident that it may be supported from any other suitable member. In case it was desired to release the grip at a greater distance from the head-support the trip D might be supported from the supporting-cable. The frame of this tripping and grip-holding device consists of two parts D, which at their outer ends or the ends away from the head-supportfiare outwardly, as clearly shown in Fig. 5. Within this outer end of the frame is mounted a sliding block or ram D, which is mounted to slide in suitable guides on the frame D and the bolts D which bolts are also surrounded by springs D acting to hold the block projected a certain amount and to return it after it has been forced inward. To the block D is connected a rope C, which passes over a pulley and downward to the lever N upon the engine, by means of which the operator may Withdraw the block D whenever desired. The outward movement of the ram or block D is limited by engagement with the ends of the bell-crank levers L, which act at different times as stops for the ram D and catches for the rope-grip. The cam-dog H upon the grip has its end It projecting beyond the side edge of the grip-frame and in such position that as it travels toward the trip it will finally engage with the outer end surface of the block D, and the grip will thus be released from the hoisting-cable by forcing the dog toward the right of its position, as shown in Fig. 4.

Upon the outer ends of the frame D of the trip are pivoted two bellcrank levers L, the longer or inner ends of said levers being of sufficient length to engage with theouter end surface of the block D. The flanges I, which project from the sides of the grip, engage the inner arms of these bell-crank levers before the cam-dog H engages the block D. The block D is thus forced inward before it engages the cam-dog H a suflicient amount to free the hoisting-rope. As the block is swung inward by the pressure applied to the bellcrank levers L the springs D are compressed. When it has been swung inward a sufiicient amount, the long arms of the bell-crank levers will swing outward a sufficient amount to clear the block D. The block will then be forced outward by the springs D and will strike the cam dog H a blow sufficiently hard to promptly release the hoisting-rope. When the ram D is forced outward, the in* ner long ends of the catch-levers L lie outside the ram and are prevented therebyfrom swinging back of the position shown in Fig. 5. In this position the short arms of the levers hook over the outer edges of the flanges I, so as to hold the grip against return. The grip will thus be held until the block D is withdrawn by hand through the intervention of the rope 0 As soon as this occurs the spring k will cause the cam-dog H to grip the hoisting-rope 0 If the drum carrying the grip outhaul-rope C is caused to turn so as to wind its rope in, the grip will be caused to travel toward the right of the figures and to carry with it the hoisting-rope G The hoisting-rope is guided in its passage through the trip device D by means of two rollers d, which are journaled in said trip device.

The operation of our device is as follows: Starting with the grip G locked to the trip mechanism (shown in Figs. 4 and 5) the engine is operated so as to cause the carriage E to travel outward upon the cableway. As the outer end of the hoisting-rope C is provided with a pair of tongsf or other suitable mechanism for engagement with the log, the end of the hoisting-rope cannot pass through the pulley F and the hoisting-rope is carried out along with the carriage. The grip outhaul-rope C is also carried out by the same means, although the speed of the grip onthaul-rope will be twice that of the carriage and the hoisting-rope, because one end of it is secured to the grip, and the grip is at that time locked in position and prevented from traveling outward upon the cableway.

In using a device of this character it is desired to have a certain amount of the hoistingrope extending beyond the carriage, so that logs may be drawn in from points extending at some distance at either side of the cableway or beyond the tail-support. When the carriage has traveled a distance from the locked position of the grip equal to the amount of the hoisting-rope which it is desired to have extend beyond the carriage, the trip is released by pulling upon the rope C The further travel of the carriage will thus result in drawing the grip outward with it, provided the friction of the grip in traveling upon the cableway is less than the friction of the drum upon which the grip outhaul-rope is wound. This may be regulated by a brake, if necessary. The grip may also be caused to travel outward by winding in upon the grip outhaulrope. By one of these means the grip is caused to travel outward upon the cableway, so as to pull with it the hoisting-rope,and thus to provide as much slack as necessary to reach the logs desired. If the amount of slack pro- I duced by this means is not quite suflicient for the purpose, it is a comparatively easy matter to pull out the hoisting-rope the short distance desired by hand, as the grip will not engage the hoisting-rope except it is moved in one direction.

The rope O has herein been called a hoisting-rope, although it is something more than that. It is, in effect, a combined hoisting and load-pulling rope, as the travel of the carriage toward the head-support is caused by the pull upon the rope 0 We have therefore in some of the claims referred to this rope as a loadpulling rope, which is correct, as it is relied upon to move the carriage in one direction.

It is evident that our device might be operated without the main or trackway cable (J, if desired, although the use of such cable has some advantages. In such case the outhaul and hoisting ropes would serve in combina tion as the supporting-ropes. The carriage, the grip, and the tripping and holding devices might be much simplified without departing from the spirit of our invention or changing their function.

It is evident that many of the parts of our device might be materially changed in appearance without changing their essential characteristics. We do not, therefore, wish to be limited to the exact form of device herein shown nor to the exact method of operating the same. The omission of any elements in any claim is to be taken as a formal declaration that the omitted elements are not essential to the particular combination therein mentioned.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1.
