The block 22 comprises two side plates 28-28 spaced from each other, and connected at one end b a connection member suspended on one of the members of the swivel connection 21. The said side plates 28 are disposed in parallel spaced relation, and between them is arranged a'pulley sheave or drum 30 mounted bearing pin 31, the of which are suplporte by the said side plates 28. This p ey sheave 30 or drum is p ro 'ded with a peripheral groove 32 having an elliptical bearing face the main cable is adapted to be wound for a plurali of turns, as will be hereinafter set forth. igid with the said faces ofthe sheave 30 arev annular sets of ratchet teeth 34, with which coperate spaced mounted upon and connected by a sleeve 36, which is pivoted on a in 3,7 having its ends fixed in the side p ates 28-28 of the block. Suitable opposite ends means. is provided for normally urging the 5o engaging ends of the pawls 35 into Contact with the ratchet teeth 34, this object 'being accomplished preferably by a weight '38, secured to the sleeve 36, on the opposite side of the pivot pin 37.

I will now proceed to specifically describe ratchet teeth are sheave 30 `will be heldl u infamousr dially of the sheave beyond said ratchet teeth, as shown in Figs. 3 andV 4 of the drawings. According-tothe present embodiment of my invention, the main cable is wrapped around the sheave 30 for a plurality of turns and is 'then carried down and wound upon a drum 40, whichdrum is revolved under take up the main cable until the (pioper elevation thereof is reached, said umforming part-of the hoisting engine which will now be described.

41--41 designate side frames in which is journaled a'power shaft 42, carrying crank disks-43, connected by pitinen 44, to pistonsv This shaft 42 has of engine cylinders 45.. loosely mounted thereon a pinion 46 adapted tobe clutched to said shaft to turntherewith by a positive clutch 47, slidably mounted on the shaft 42 and adapted to .be

operated in any suitable manner. y The pinion 46 meshes with a gear 48, ixed'to adrum shaft 49, upon which shaft is mounted the vdrum 27, heretofore mentioned, said drum 27 being movable longitudinally of the shaft 49 by means of a thrust mechanism 50, to connect said drum to the gear 48, by means of friction clutch surfaces by the drum and said ear 48, respectively. The gear 48 isv provide /to the clutch face 52 with a circular series 51, A52, carried,

on its side opposite of ratchetteeth 53, adapted -t0 be engaged i by a pawl 53", to hold the tation when the latter is frictioially connectedto the gear 48. The opposite end of the :drum 27 carries an annular braking sur? receive a band brake 54". Loosely` 5,5 adapted face 54, to

mounted on the shaft 49 is a gear to be clutched to the shaft to turn therewith drum againsthroby means of a clutch 56, operated in any suitable manner, said gear 55 nieshin with a large gear 57, on one end of the 40, heretofore described. The drum 40 carries at one end a `circular series of ratchet'teeth 58, adapted to be engaged b a pawl 59, whereby said drum may be he d against rotation under pull of the main cable. Fixed to the shaft 42l is a pinion 60 meshing with a gear 6l, on'a shaft 62, said gear 61 being located between the drums 63, ed to be connected to either, or both, of said drums byfrictions 63, 64. f The drums 63, 64, respectively, operate the changing lines, not shown, for laying out themain cabl between the headftower and. the tail-tower before said'main cable is elevated. Both of the drums63, 64, may be provided with suitl able braking faces .-65, 66, with which co operate band brakes, not shown.

will be suiiicient to out the..

main cable.l lThe-drum 40 may also. be provided with a braking surface 40, ,with which coperates a band brakeflQl for` retarding rowould wrap-the -ropeabo, tfsaid sheave four r would be attached to Under such anvarsheave 32 is locked times befgre/the ropeI tige/winding drum .40;

lagainst rotation/by the pawl being engaged cal or curved form of the therewith afpju'll or a load on the main cable of say 134,000 pounds would be reduced to approximately 27,000 pounds on the holding drum. This is accomplished by the elliptigroove of the sheave 30, which causes the turns of the rope to frictionally engage each other and the sheave, and the friction caused by the number of wrappings of the main cable on the sheave and the large diameter of the sheave.

In operation the main cable iswrapped around the sheave 30 for the required number of turns, and is then carried down and Wound about the holding drum 40, which, being connected through the clutch mechanism to the driving shaft of the engine, is operated to take up the main cable until the latter reaches the proper elevation. The pawls 35 then engage with the ratchet teeth 34 to lock the sheave against rotation permitting the paying out of the main cable, and the pawl 59 is thrown over to engage the ratchet teeth 58 on the holding drum to prevent rotation of the latter to pay out the main cable. When it is desired to lower the main cable the drum is disconnected from the driving shaft, the sheave 30 is released from the pawls 35, and the holding drum is permitted to rotate under the restraint of its brake until the main cable is lowered to the desired position.

I provide means for conveniently disengaging the pawls 35 from the ratchet teeth 34, said means preferably consisting of a pull cord 38a, passing over a pulley or guide roller 38", arranged between the plates 28 'and turnlng on a cross pin 38c fixed in said plates, one end of said cord being connected to the pawl weight 38, as at 38d, and the other end depending to a point of easy access to the operator. It will be understood that a pull on this 'cord will lift the weight for any reason.
