AUGUST SUNDH, OF HASTINGS UN HUEGN, NEW YORK, ASSIGNOR TO QTIS l:Elli -I i VAT-0B, COMPANY, GF JERSEY NEX-V JEMEY, A. CGRPQRTCN frneofrioinnnvafroe.
To all whom it may fonderie Be Lit known that I, AUGUST Suxnin a citizen of thejUiiited States, residing at Hastings upon Hudson, in the. countyy of Westchester and State of New York, have invented 'a new and .useful Improvement in g is a. specification.
lily-invention relates to frietional drive.
apparatus, particularly adapted for use with and as forming part of traction elevators,
A and like apparatus.
This` application is a division of :ny en pending application, Serial #380990, filed June 27, 1907.
' In a direct drive velei-'ator system, conn` :monly known as a. traction elevator, and
Where n, friction sheave on the hoisting niotor` shalt imparts niolo the elevator ear and*counter-nalanee directly, that is,y without.tlieintervention of a winding drum and 'theworin gear, itis oit the greatest importance that there shall heno 'slipping of the cables in relation to the hoisting oi' driving" slieave. The necessity for some 'remedy Which'will eiliiectuallvremove this chief objection to traetion elevaiors is well known to those` versed in the ari', The present invention aims to overcome this objection by providing a facing of leather or like. nia'te-- rial for the hoisting cables, said .facing he ing interposed between the drive alieave and the cables, so that the-'tension and strain are taken 'n i iii/the cables while at the saine time, the leather facing furnishes a goed friction Contact.
Qther objects of the invention and the precise nature thereof will appear more fully hereinafter.
Referring to the accompanying drawings,
Figure l illustrates ay traction elevator, embodying the present invention; Fig. 2 is a x .i "a, I
" opposite ends of thefeifililes,gk A'b'eit or bei? is found toistrei,
it is advisable as ldie Galilea, the straps ning b This will depend" .upon tiie duty and str-airing' 'i [illustrates ale-ata 4 he traction su drive shea 7'.' Tl'iis Ai :fo further increasing thetraf'tiv l l'Vliere a belt is; used fr sion, Whether. it he 'of ton or other materia-l, it i t, subjected to great Wear,v` strainon the helt'isv conside ab'l ,Where the tensile strain is.reducedtd4 ttl O Ifl'fdli ing, it is found that there k i' i Wear at all. It is also elevator practice, where t e tionable for various reasons. It causesl rapid Wear of the cables, necessitating Lfrequent and expensive repairs. It lowers the ellicie-ncy, and prevents comi'ilete and positive cont-rol of the elevator, thereby introducing an element of danger, and reduces the speed and accuracy with which the elevator may be operated and controlled, and is otherwise objectionable. By the use of the present invention, as above explained, these objections are overcome and the advantages of the use of belli the steel hoist cables, and the leather /belting are obtained Without the,disadvan tage or objectionable features incident to the use of leither alone. `Furthermore, in the case of an arrangement as herein shown, the ielt 5 partially balances the Weight of the steel Cables. The. length of the belting' is ioo is secured to somewhat ymore than the run of the car, thatl is,it- Lsuoli length as 'to remain 1n con 4tact with' the drive sheave throughout the travel of the car, but does not extend to the portions of the cables running on the overhead sheaves. s Y
I lWish not .to be limited to the precise con- .struction and arrangement of parts'herein .shown, as various changes might" be -made `withoutl departing from the spirit and scope ofmy invention.
What I claim as new and desire to secure by Letters Patent of the United States is A1. InA an elevator, the combination with a w car, of a counter weight, a cableuniting the carvand counterweight, a pliable-facing for a portion of the cable, and a Ydriving pulley in 4.frictional engagement with the pliable facing. f i f i. 2. yIn an elevator, the'combination Witha driving motor, of :adriving pulley connected thereto, a car, a counterweight, a cable-uniting the car and counterweight, and Apassin around the driving pulley anda belt secure to the cable and in'terposed'between the drivf' ing pulley and thecable.
3. In an elevator,i the combination with a. car, a counterweight Vand a cable or cables Y connecting the car and counterweight, of a drive pulley or sheave associated with said cable-sand leather facings l'on the pulley and cables in frictional engagement with each other.
.4. In a tractionelevator, the combination with a car, a counterweight, and a cable or cables uniting. the carand counterweight, of a flexible facing for a portion of the said cables, a drive pulley -or sheave, and a leather facing for Said sheave, said leather facing being in frictional driving engagement with the flexible facing of the cables.
5. In an elevator, the combination of a car, a hoisting cable, a drive sheave, and
leather` facings interposed between the drive sheave and cable and secured respectively` to the sheave and cable.
6. In an elevator, the combination of a car, a hoisting cable, a drive sheave, and a leather facing carried by the cable and automatically adjustable thereon to compensate for relative stretching of thecable and facing.
' 7. In an elevator, the combination of a "car, a counterweight, a drivesheave, a plurality of cables, connecting the car.. and counterweight Vand extending around the drive sheave, and a strip of leather forming a facing for the cables and interposed between the cables and drive sheave.
8. In an elevator, the combination of a car, a counterweight, cables connecting the car and counterweight, a drive sheave around which the cables extend, and a leather facing carried by the cables and partially counter-balancing the cables.
9. In an'elevator, the combination of a car, a counterweight, direction sheaves, ca-V bles connecting the `car and counterweight, and .running in direct contact with said sheaves, a drive sheave, and a leather facing for the cables positioned to run :in continu? 'two subscribing Witnesses.
