APPARATUS FOR VARIABLY-LOAVDED WORKING Application filed February 1, l'szalserial No. 690,035. r
1 To all whom z't may conoem Be it known that :I, LIADS-V'LIE Boizorn GREVINK, asubject of the King, ofNorway,
residingat Sofiesgate 60, Chr1stiania, Norway, have invented certain new and useful Improvements in Speed-Controlling and Driving Apparatus for Variably-Loaded Working Machines, of which the following is a specification.
In mines there are often used ore separators, which include anarrangement in which great rotating arm crosses or spiders carry, at the free end thereof, buckets, which buckets when in top position receive a charge 1 of ore and then lower the charge when the spider turns, and finally deliverthe charge when in lowermost position. When such a spider is running idle, the buckets receiving no charge, only very little force is necessary to turn the spider at constant speed. I-Iowever, when the buckets receive ore charges the heavy load of the several filled buckets on the one side of the shaft of thespider,
exerts a considerable momentum, and in order that the speed of the spider shall not increase, it has heretofore been necessary to use a powerful motor or prlme mover,
which counteracts the said momentum with out being dragged with the spider. When the spider was running idle the said powerful motor had to be braked, and thereby considerable energy was lost. 7
The present invention aims at removing this drawback. With this object the invention consists of an apparatus which is adapted to drive a spider, or other arrangement of the type said above, at a substantially constant speed, the motor being, however, far less powerful than those previously used, whereby energy is saved.
On the drawing, which shows one embodiment of my invention by way of example, Fig. 1 is a side view of the regulation apparatus, and Fig. 2 is a top view thereof, partially in sect1on.
The shaft 1 is connected to the machine or other arrangement (not shown), the speed of which is to be controlled, eventually by means of a suitable gearing. The said shaft 1 is journalled in the pedestal 2, suitably by means of a roller-bearing 3. Fast on the shaft 1 is keyed an internally geared wheel 4:, which thus turn together with the shaft 1. In the hub portion of the said wheel 4 is located a roller bearing 5, which supportsthe end6 of a arranged in alignment withtheshaft 1 and alsosupported: bya pedestal .8. .The'shaft 17 is prevented from turning inthe pedestal 8 and the roller bearing 5, by suitable means, such as a setscrew 9, screwed through a part ,of ithe pedestal 8 into contact withfthe -sh aftf7.qi
-O-n the stationary shaft 7 is mounted a frame 10, which maybe rotated on the shaft 7, and one end of which forms the stator 11 of an electric motor. On the shaft 12 of the armature of the said motor is keyed a gear 13, meshing with a gear 14 fast on the stationary shaft 7. The other end of the armature shaft 12 carries, fast thereon,
' a sprocket wheel 15, which through a chain 16 and another sprocket wheel 17, drives a shaft 18, which by means of roller bearings is rotatably mounted in the end of the frame 10 distant from the motor. The other end of the shaft 18 carries, fast thereon, a gear 7 19, meshing with the internal gearing of the wheel 4. Current is supplied to the motor in a way well understood in the art, suit-able contact rings 20 being arranged upon the shaft 7 and coacting with suitable brushes 21 secured to the frame 10.
The frame 10 is carefully balanced on each side of the shaft 7, the weight of the motor and the corresponding part of the frame 10 on one side of the said shaft counterbalancing the weight of the gears 17 and 19, the
shaft 18 and the portion of the frame 10 on that side of the shaft. If necessary suitable weights may besecured to the frame on one end thereof in order to obtain exact balance. The frame 10, instead of being integral with the stator of the motor, may be formed to receive an electric motor of usual construction, which is secured to the frame by suitable means (not shown).
Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is:
1. A speed controlling and driving apparatus for variably loaded working mav paratus for variably loaded working inachines including a main support, a shaft journaled therein, a stationary shaft in the support and in alinement with the rotatable shaft, a support loosely mounted on the stationary shaft, a motor rotatably mounted on the support, gearing between the motor and the stationary shaft, and motion transmitting means for operably connecting the motor with the rotatable shaft.
3. A speed controlling and driving apparatus for variably loaded working maehines including a main support, a shaft j'ournaled therein, a wheel, the hub of which is rigid with the shaft while the rim is provided with internal teeth, a stationary shaft lraviing one end mounted in the motor and the other end operably mounted in the hub of the wheel, a secondary support rotatably mounted on the stationary shaft, a motor carried by the support and including a shaft, gearing between the motor shaft and the stationary shaft, another shaft mounted in the secondary support opposite the motor,
-a gear on the last mentioned shaft meshing with the internal teeth of the Wheel, and means for operably connecting the last mentioned shaft and the motor shaft.
4. An arrangement as claiined'in claim 3, wherein the means for connecting the motor shaft and the shaft on the secondary support include sprocket wheels keyed to said shafts, and a chain operating about said sprocket wheels. 7
In testimony whereof I. afiixymy signature.
