IMPRVED HOISTING- APPARATUS.
The Schedule referred to in these Letters Patent and making part o! tho lame vented a certain new and usefulr4 Improvement in HoistillgjAppax-atusi,and I do hereby declare t-he following, toA be a suIiieie-ntly full, clear,- and exact description vthereof'tp .enable one 'skilled 'inthe art' to which m'y invention appertains to make 'and use-it,
reierencehenghad to the accompanying drawing making part;4 ot-'this specification.'
Nat-ure and O bjeets of Invention. '.Myinvention relates to hois'ting'appaiinisns il'rwhich a'lrope or chain' is used to'snppnrt the load,'and consistslin agcerlzniuprovisioxrand combination o t' driv-v ing-'sexism sliding aml st'a.tlonary pulley-blocks, and
' rope or chain, which the (hi ving-powerfis connected -to the: hoisting-platform-or weight; t-o be raised by simple and etieier1t -n\eans, and in sueh' a way that .t-heweigh is' sustained]at all times, 'eren after the power is' thrown ofi'.
' The objeetiot'- my invention is the production of an 5 apparat-ns in which winding-dimm for the-rope or balance-weights for the load are entirely avoided. Description of dcconiyanying D'ruvintgl` The accompanying.'drawing represents in perspective the essentiaifeatures of my-inrention, fa portion of the case, eontainlngthe sliding pulley-block, being removed to ezihibit interior arrangementi ot' the parts.
GmerZ-Deserptom A A' A represent a series of shyepnlleys, permanently journaied in the case B of the apparatus,
.and
C C'represent; similarly-constructed sheave-pnlleys, jornaledin the slidingbloekD.
Eis the hoisting-rope or elmin which supports the l oad.- It is att-achedmtone end to the sliding block D at.'
d, and, after passing in succession overthe sheavepulleys A C A' C' A", it connects in the manner shown, or in any preferred way, to the plat-form or load F.
Idler shcave-pulleys G G' may be used at p leasure, to give direction 'to the hoisting-rope or ehain E.
The load is raised'or' lowered simply by the sliding motion of the block D, and this block is operated by the screw H, which is journaled at both ends 1n the.
'lhe screw H may be operated by hand or power,* and maybe connected in any preferred way to the motor.
Ib will he readily seen that, although the screw enh impart mot-ion to the load n the manner shown, the load cannot reverse the act-lon and move -the screw. The load, therefore, is at all times safely supported, and cannet run down even when the driving-belt i5 thrown oor the driving-power otherwise removed.
My apparat-us isohviouslyapplieable to cranes, d rrcks, and other machines for raising or lowering lo( s- Where il; ls used in connection with a hoisting-platferm, the customary safety-catchescan be employ@ to 'snppoiia the load in case of the breaking ofthe I do not desire to eonne myself to the use ot' a specified number of pulleys A4 or pulleys C, as the.
number will, of course, he determined by the wbrk to be done.
