cmcmr eonraoun a.
To all whom 'it may concern:
Be it known that we, J OHN P. COLEMAN, a citizen of the United States, and resident of the borough of Manhattan, in the city, county, and State of New York, and PER UTNE, a subject of the King 'of Norway, and a resident of the borough of \Vilkinsburg, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Circuit-Contrcllers, of which the following is a specification.
Our invention relates to circuit controllers.
We will describe a circuit controller embodying our invention and then point out 4 the novel features thereof in claims.
In the accompanying drawings, Figure 1 is a view showing in front elevation a circuit controller, part of which is'cut away to show a portion of an operating mechanism therefor, embodying our invention. Fi .2 is a sectional view on the line IIII of Fig.
sectioned, showing on a larger scale the operating mechanism shown in the preceding views and embodying our invention. Fig.
4 is a sectional view on the line IVIV of Fig. 3, looking in the directionof the arrows. Figs. 5 and 6 are views showing in perspective two counterweights comprised in the operating mechanism shown in the preceding views.
Similar referencecharacters refer to similar parts throughout the several views. Referring now particularly to Figs. 1 and 2, 9 designates an inclosing casing or framework in which are mounted a circuit controller 10, an electric motor 11, and a mechanism 12 for the operation of the circuit controller by an armature 18 of the motor device. w
Briefly described, the circuit controller 10 comprises a circular contact carrier 13, preferably of insulating material, such as porcelain, in which are mounted contact fingers arranged to project radially toward the center. As here shown, these contact fingers are in sets, each set comprising two stationary fingers 15 and a movable finger.
14. At the center of the contact carrier is a contact operating member, here shown as being a rotatable drum 16, preferably of insulating material such as porcelain, which Patented Nov. 21, 191i.
drum is provided with slots17 adapted to receive. the end of the movable contact finer 14 of each set and to movesuch finger into contact with either of the stationary fingers 15 of the same set, depending on the direction of rotation of the drum.
The motor 11 may beof any suitable type which is adapted to cause its armature 18 to rotate in either direction.
The operating mechanism 12 between the armature 18 and the drum 16 of the circuit controller comprises a pinion 19 mountedupon a shaft 34 of the armature 18 and op- ,eratively connected therewith in a manner the shaft 27 is a crank 30 which is connected each set is held out of enga ement with each i of the stationary contact gers 15 of the same set. i As here shown, the drum is biased to this middle position by gravity, by means of counterweights 21 and 22 whichare shown in perspective in 5 and 6.
-These counterweights are mounted to rotate freely on the shaft 27. Their rotation in a downwarddirection under the influence of gravity is limited by means of a stop 31 here shown as being a screw mounted in a portion 32 of the framework 9. As here shown, the upper portions of these counterweights are cut away in such a manner as to permit them to telescope whnone or the other of the counterweights is rotated upward, and the amount of upward rotation of each one is limited by the engagement. of an edge 35 of each counterweight with a face 36 of the other. A crank pin 33, carried by the segmental gear 20, engages the counterweights 21 and 22, and when there is no torque exerted upon the segmental gear, the counterweights act upon the crank pin 33 to hold the segmental gear 20 and the drum 16 in the middle position, in which position the parts of the apparatus are shown in Figs. 1. and 2 of the accompanying drawin s.
The operation of the apparatus as thus far described will be readily understood. When the motor device ll is deenergized, that is, when no torque is exerted on the armature 18, the counterweights 21 and 22 will act on the pin 33 to hold the drum 16 in 1ts middle position as hereinbeforeexplained. Vhen now the motor device is energized and the armature rotated, the drum 16 will be -rotated, thus moving the movable contact finger 14 of each set into engagement with r one or the other of the stationary contact fingers 15 of the same set, depending on the direction of rotation of the armature 18. During such movement, one or the other of the counter-weights 21 or 22, depending on the direction of rotation, will be raised by the pin 33. The rotation of the drum 16 is limited by the engagement of the edge of each counterweight with the face of the other counterweight as hereinbefore explained. The parts will be held in the positions to whichthey have been moved as long as the motor device is energized, but as soon as the motor device is deenergized,
thus removingthe torque on the armature,
the counterweight which was raised will act upon the pin 33 to move the drum 16 and the apparatus connected therewith back to the biased or middle position. The operation of the apparatus is similar for a movement 7 of the drum 16 in either direction from its middle position.
It will be evident from the foregoing eX- planation, that while the drum 16 is being moved back from either of its extreme positions to its middle position bythe action of one or the other of the ' counterweights 21 or 22, the armature 18 will also be rotated,
and if no means were provided for absorbing the inertia of the armature when the middle position of the drum is reached, this inertia would carry the drum beyond the middle position and might move the movable contact finger 14 into momentary'engagement with the stationary contact finger opposite to the one with which it had just previously been in engagement. To prevent this, we provide means for absorbing the inertia of the armature without moving theglrum 16, which means we will now descri. e.
Referring now more particularly to Figs. 3 and 4 of the drawings, it will be seen that the pinion 19 is mounted to rotate on the.
It will now be clear that when the drum 16 has been moved back to its biased or middle position by the action of one of the counterweights 21 or 22, the armature 18 may continue to rotate independently of'the pinion 19 through substantially one revolution after the middle position of the drum 16 has been reached. This one revolution might not in itself be sutficient to expend all inertia of the armature, but We provide for absorbing all of the inertia-during this revolution by means of friction between the pinion 19 and the shaft 34. As here shown, the device for creating this-friction may be described as follows: 37 designates a collar secured to the shaft 34, between which collar and the pinion 19 is a washer 44 of a suitable soft material, such as raw hide, which washer is free to rotate on the shaft. 43 is a similar raw hide washer on the other side of the pinion, and 38 is a metallic washer, both of which washers rotate freely on the shaft 34.
42 designates a nut adapted to turn on a threaded portion of the shaft 34. Between this nut and the washer 38 is a spiral spring 30. The compression of this spring may be adjusted to give the desired friction between the pinion 19, the washers 38, 43 and 44 and the collar 37 by rotating the nut 42, after which the nut may be permanently secured to the shaft in any desired manner, for example, by means of a pin as shown. The adjustment of the spring 39 is such that the friction between the pinion and the shaft is insufficient to move the segmental gear 20 against the action of either of the counterweights, but is sufficient to bring the armature 18 to rest during one revolution or less. It has been found by experiment that such an adjustment is entirely practicable and may readily be obtained.
The operation of the entire apparatus will now be clearly understood. When the motor 11 is energized,'the armature 18 will rotate independently ofthe pinion 19 until the pin 41 engages the pin 40, when the segmental gear 20 and the drum 16 will be rotated to move the contact finger 14 of each set into engagement with one or the other of the contact finger 15 of the same set. When the motor is again deenergized, the entire apparatus will be rotated in the opposite direction by the action of one of the counterweights until the middle position of the drum 16 is reached, at which point the action of the counterweight will cease, owing to the engagement of this counterweight with the stop 31. The rotation of the drum 16, and the segmental gear 20, is so slow that the inertia of these parts will not carry them any apertia will'be absorbed by friction as herein-' before explained.
