i T all whom it may concern:

and "thus prolonging the life of the whole cable. 1 accomplish this result by provid-- ing devices for successively and automatie cally rotating all of the cables about their Be it known that I, NAPOLEON P. 'JULIEN, a subject to the Kingof Great Britain, residing at Springfield, county, of Hampden, Commonwealth of Massachusetts, have invented vcertain new and I useful Improvements in Elevators, of which the following is'a specification; c

This invention relates to improvements in elevators of the type in which cablesare used to support the car and counterweight; Such cables are usually carriedgaround a hoisting drum, either'with the single wrap;

or multiple'wrap traction construction. In

the present invention it is designed to use. drums with the single wrap traction con struction. It has beenwfound in practice that some of the strands of the wire cables onaccount of the wedging action and excessive wear between the grooves of the drum and the sides of the cables produces so much wear on comparatively few of the strands of the cable as to weaken them} and consequently the whole cable; necessitating the substitution of new cables. Thisfisubstitu "tion'of new cables is a 'very expensive part of the maintenanceot this class of elevators.

- .An object therefore of the present in f kvention is to provlde means for overcom ng this excessive wearon a few of the strands axes; for the purpose of presenting new wearing surfaces ofthe strandsl'of thecable to the sides ofjthe groove of the drum,

whereby owingto the rotative movements .of the cables about their axes the entire circumferential surface of the whole, cable will wear uniformly and thus life of the same.

The invention broadly considered comprolon g the prises devices operable-during the travel of the car and counterweightwhich will I simultaneously impart arotary or twisting movement to thecable strands and in opposite directions so that the twisting move ment of one end'of the cable will becounteracted by the twisting movementof the or) posite endjthus maintaining the cablejin good condition atllall times.

These bolts extend downward between the webs of the channel irons 12 which pawls 23 (see Figs. 8 .are secured to the lever arms 24 which are are secured to thetop of the car. .Their. lower ends pass'through the plate 13. 14 are ball race plates for receiving the balls of the bearing indicated at 15 and 16 is a plate loosely mounted on the worm 18, the pawl 23 being, as shown located between the arms 24"01 the arm24. The upper ends of these arms are provided with rollers 25 (see Figs. Zlahd 1.), which rollers engage the inclined surfaces26 of the depending cam members 27 thatare secured to the overhead frame- .workof the elevator well a portion of which is indicated at 28.

For the purpose of actuating the arms 24 for holding the rollers 25 in contact with the cam surfaces 26 weights 29 are provided which are secured to the arms 30 that are secured'to the arms 2 1-. 31 indicates a stop to A limit the downward movement of the weight 29, and to accurately position the rollers 25 so that they will not pass by the lower ends 27 of the members 27; y c It will be seen that when the car reaches the upward end of its travel the rollers 25 willengage the inclined plane or cam surfaces 26 causing the pawls 23 to engage the ratchet wheel 22 and impart rotary movement to the worm 18, whichin turn, will rotat'e' the gears 11, on one side of the worm 18 in onedirection, andon theopposite side vof the worm 18 in an opposite direction,

thus, imparting a rotary or twisting move- 'ment to the cables 4, 5, 6, 7, and 8.

For the purpose of simultaneously imparting a rotary or twisting movement to their attachment to the top of the car.

the other end of. the cables they are attached to the counterweight 32 111 the same manner as thatalready described inconnectionw1th A worm shaft 33 is suitably mounted for rotation in the bearings 32 on theupper ends of the bar 32 that support the counterwveiglits. This shaft is provided at its opposite ends with ratchets 3 1 which. are pinned to the shaft 3321s indicated at 35. 36 is a pawl carried by the arm 37 which arm is providedwith aroller 38, that engagesthe inclined plane or cam surface 89 of the memher that is secured to the framework at thehottom .ofth'e elevator welhwhereby on the descent of the 'c'oun'te'rweightthe w'orrn the same as that shown in Fig. 2. Secured to the lever 23 is a weight 11 by means of the arm 42, the purpose. of which is to maintain the roller 38 in the same position or alignment so that it will always engage the inclined surface 39.

I have shown ratchet mecha- Although nism at the opposite'ends of the shaft f18-it,

is obvious that a single ratchet construction at one end of the shafts 18 and 38 would be sufiicient. By using the construction of worm gear and worm,there is 'a reduction movement between the shaft 18 and the cables for the purpose of imparting only a small rotary movement to the cables at the ends of the travel of the. car and counterweight when the car is atthe upper ends of the travel the counterweight is at the lower end, p a 5 Referring to Figs. 6 and? which illus-' trates the position the cables assume in the grooves 4L3 of the drum 44:, it will be seen that the strands of the cable at the opposite sides of the same are the ones that receive the constant wear. This result is produced by the pinching or crowding effect due to the more or less V-shape of the groove 13, since the cable does not completely. fill I, the

groove. My invention is designed to over-' come this wearing effect ofthe same strands which are constantly brought into contact I This is accomplished .by

with the groove. 7 providing devices to nnpart arotary movement to one end ofthe cables as indicated bythe arrows 7,..(see Figs. '6 andf'?) to the p The arrow 72 illus trates the idea of imparting rotary motion;

cable 7 for example.

in an opposi'te direction to the oppositeend of the cable 7, whereby the two ro-tary' movements will counteract each other and thus maintain the original length of the cable,

By employingmeans to successively and automatically effect these rotary movements" in a step by step manner the life of the cable will be materially inci ease d hat T'claim is: 1
