Description

dles 22 and and drive-the drums at any vdesired ratio. i
The underlying thought of the invention is to provide a mechanism such that'if one ot the secondary drums (e. g. l0) be held against rotation (as by band brake 2Ll--26) the free secondary druin (e. g. 1 1) will revolve through its operative connection with the primary or hauling (lrum 12 in its defi; nite ratio, thereby controllingin definite fixed paths the bodies hoisted or hauled' by the drums. At the saine time, the option is afforded ot' usingeither of the two secondary drums by simply releasing one and holding the other without upsetting the fixed ratio between `the chosen drum on the driven shaft and the, primary driving drum which moves when -eitlier ot' the secondary drums turns.
vAn obvious use of the device would be to release both brakes and pull simultaneously on both secondary drums l0 and 11, in which Case, if the drums were of the same diameter, the'pull on both ropes would` be the same, or by making; the secondary drums of different diameters any selected ratio could be established between the pull exerted by the ldrums respectively.
.Other possible modiications will readily occur to those slil-led in the art` Which do not depart from what I claim as my invention. K
I claim as my inv ention:-
l. In a hoisting-engine, a primary drum, a pair of secondary drums, and means associated with each of said secondary drums for hauling a load independent of the other secondary drum, a drivingconnection between the primary and' secondary drums,
.means t'or halting one of said' secondary druins on the drive of the other secondary and the primary drum. the sum ot the revo-l lutions of the, secondary drumsJ when both are `driven simultaneously beiner equal to the revolutions ot one secondary drum when that is driven aloneand bearing ya prede-- termined iixed ratio to thel revolutions ot the primary drum. for the purpose described.
2. In a hoisting engine, a primary drum, a' pair of secondary drums, and means associated with each ot' said secondary drums for hauling a load independent of the other secondary drum, av driving connection between the primary and secondary drums,
readies means fort halting either o said secondary drums on the drive of, the primary drum and 1 the other secondary, the sum ot the revl u' tions of the secondary drums when both are driven simultaneously being equal to the revolutionsl of one Secondary drum. when y lequal and having' a priaieteriuiiied line ratio to drinn.
4. In a hoisting,A engine, a primary drum, a pair ol secondary drums. and means assothe revolutions ot the primary ciated with each ot' said secondary drums ieiideiit et' the other for haiiliiiler a load in secondary drinn, a di, entail drive. gearing operatively connecting; `the iiniiiiaryand seeondary drums, and means for halting .ther of the secondary drums to permit the drive ot' the other secoi'idary drinn at accelerated speed.. the revolutions of the secondary drums combined or of either alone being' equal and havingra. predetermined fixed ratio to the -re volutions of the primary., drum. K l
5. VIn a hoisting mechanism, ay dump cer and a pair of skips tor filling the same., a primary drum for hauling the dump car' and a pair of secondary drums for lifting the filling;r skips, means for driving the primary drum. a differential driving* connection between the primary drum. and the secondary drums. and means tor holding either o f the secondary drums to permit the other secondary drum to run at accelerated speed, sub-- sta'utially as described.
In testimony whereof I have signed my name to this specitieation.v in the of two subscribing witnesses.
