The invention consists primarily vithere'fore'in providingapparatus of the kindin question with reversing means'which when set in action automatically hold each clip operi when itsmoton relativeto .the rope is such that the clip' would normally grip.A The arrangement must be such that hoth clips are net open together, though the Y.

reversingmeans may be adapted by aiurther adjustment to open both clips to facilitate threadf` ing of the rope `through the apparatus.

At its lower end the plate 26 has an aperture 40 and is held tothe plate 1 by'frictional holding 'device 41 'similar to that describedfabove.V A

. e retaining Ydevice 42` enables the pivot 20a of the lever 20 to be held in position, whether this pivot is mountedl inl the aperture 21, :or the aperture 25, As will be seen-in FigureY 9a the device42 secured to the plate 1 has two grooves 42a, 42h respectively yadjacent the apertures21 and 25. The pivot 20a has a shoulder 20h cut off at 20c; Vthe pivot can be turned to bringthe shoulderinto the groove 42a and 42h as seen in Figure 9a.or it can be turned to bringthe cut orf part 20c adjacent the groove when the pin can be withdrawn or inserted.

Inthevaperturef27 of the-plate 26 isv asubstantially triangular plate43 'having a tail piece 43a.. The greater' part of thepiate 43 `lies in the same plane as the plate 26, but the tail piece a is bent outwardly as seen in Figure 1 so that it can move over-plate'26 when necessary. There is aperture 44 in plate 43 through which` passes the movingpivot 45 ofthe upper links 9 of the lower clip. `The aperture 44 is shaped as shown,` similarlyto aperture 29A described above, sov that whenthe plate is in the position shown in Figuresf7, 8 and 9v with the pin 45 in rits .left hand end thepin cannot move longitud'inally with respect to the plate, but `when the plate is in the. position shown in Figure 6 zwith theV pinat the right.` hand end of theaperlture, the pin. can move longitudinally withl re-V spect to the plate la distance sufficient or'opening' and closingthe lowerfjaws; Through a second aperture 46 in plate 43allowing the latter a'certain amount of longi-tudinaland transverse movement, there passes` a pin 47 mounted on the cheek V17 of the `lower clip,` the vpin vcarrying'a` similar device to that above described for'holdy. ing f the plate 43 infrictional engagement with thecheek 117-. A slot .(54, Figures 8 land 9) is provided in the plate 1 suiiciently long to allow for the motionof the pins'45' and 47 which is substantially along theline 28. l 'A An abutment 48 v,with two opposite parallel ramps 49 and 50 is secured tothe reverser 26 f by a pivot; 5l anda stud 52. The abutmentcan Ybe removed and reversed when there is-a changeV of ratio, 4thatisto say whenthe pivotall axis of the lever is moved from V2l to 25, and in this position'stud 52 passes through the aperture`-53 Vin the abutment. Figures 6, 7 and 8 show Vone V position and Figure 9 the other. f

The, apparatus Operatesas followsz-l- 01j. Hauling crafting y *For 'this action the eVel" 33 lof thev reversing 'I' mechanism isfmoved to the lleftto the position shown in Figure 6." It `will-be observed that this position the" reversing mechanism is out'of.

The lever is pressed 1,929,686 y Yaction because the elongated Vparts of the aperthe cable is moved and with it the load which it supports, by an amount equal to the displacement of the lower clip. i l Y During the upward movement of the lever; vthe llower clip releases the cable and leaves it free'.

vBut Vthe latter is heldl by the upper clip which grips it and prevents its sliding. During this up`` ward movement of the lever, thereis no progression n or retrogression of the cablewhatever the load carried by it. 'Y

It will be observed that as above described the reversing mechanism remains out of action dur-` ing hauling or'lifting'.

2. Lowering or paying out under load` For executing this movementgthelever'33 of theY reversing'mechanism is turned'to the right,

to the position indicatedin Figures 7 and 8. It

will be convenient for purposes of description.

to assume this .is done when'thelever 2Q isinits uppermost position as shown in Figure 7, though in practice the change can be 'made infanyposiy.

tion of lever 20, 'A s inthe uppermost'position of the lever there is 'no tension in the` part of the cable below the upper clip, there isY no pull on y.

the lower clip and the frictionalA hold ofthe pin 47 on theplate 43 'is suiiicient'to prevent the moves plates 46 and 43 to the right and the upper edge of aperture 44in 'plate 43 causes pin 4,5,to`

move downwardstowardsthe pinv 47, thus opening thelower clipras willbe readily'un'de'istood by reference to Figure'. v

During the downward movement of. the' lever.

20,`-the pins 45, 47 remain inthe same relative position owing to the frictional gripv of plate 43 against cheek 17 andthe lower clip is heldlopenv during part .ofA the stroke, thecable remaining Vgripped by the upper clip. ,Atg'acertainpoint in the downward movemenathe" tail piece 43a of the part 43 strikes the ramp y49 ofthe abutment 48. Thisis carriedby plate'26 'which is heldstrongly in positionv by the pull in the'upper clip which holds the plate 26 by the engagement of the pin 30 with the left hand end of aperture y29 inv plate 26. From this'moment,l the' plate 43 remains stationary while the pin 47, being mounted on cheek 17 which is being moved by thelever, slides along the'faperturev 46. thus moving pin 47 lawayfron'x -pin 44V which closes the lower clip and causes it to gripthe cable. When' the pin 47 has reached'the upper end ofthe slot 46 further movement of` the lever 20 mustfmoveV plate43-which through its tail ypie'ce'43a andthe abutment 48.carriesl the plate'v 26 along and the upper clip' will be opened, owing to` 'the pivot 36v being moved downward by thefleft hand end of.

aperture 29 in'p1ate26. Y

As atrthis 4time the cable is gripped by the lower clip, ,the pull on the. vcable which is relatively great, .will be tending to pull `pin y45finthe jaw 11 away from pin 47 on cheek 17. This pull latter sliding withrespect to 'pin' 47,. whnthe'; 115 l lever '33. isv turned.. This turning of the lever f both clips.

will be greater than the resistance to motion of the plate 26 produced by the friction devices at 35 andY 41. Consequently during 4the upward movement of the lever 20 when the lower clip nears its uppermost position and the upper edge of .plate 43"cornes.in tol contact with the upper edgeof aperture 27 inrplate 26, the plate does not check plate 43 while pin 4'7.moves upwardly, but on the'contrary, platev 43 'carries ,plate 25 upwardly `and by raising pin 30 closes thel upper while the pin 47 slides in slot 46 inthe stationaryA plater43. The cycle can then be repeated.

3; Liberation of the cables y For this, the cable must of -course be free from`- load, i. e. free at both ends.j The lever-20 is moved to its extreme upper position and the lever 33 toits extreme right hand position as indicated in Figure 9. y

In this position abutment 38' presses the plate 26 downwards through the pin 39 thus pressing pivotsf30 and 45 downwards and opening or out of the apparatus by the action of the hand alone. V Y
