WILLIAM A. TURBAYN'E, OF 'N'IAG-ARA FALLS, NEW YORK, ASSIGNOB TO U. S. LIGT I HEAT CORPORATION, OF NIGABA FALLS, NEW YORK, A CORPORATION OF NEW .roma
ELECTRIC REG'ULATOR.
Specication of Letters Patent.
Patented Nov. 4., 1919.
Application led April 23, 1517. Serial No. 163,835.
To all whom it may concern:
Be it known that I, WILLIAM A. Ton- BAYNE, a' citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New, York, have invented new vand useful Improvements in Electric Regulators, of which' the following is a specification.
The present invention relatesto electric regulators.
A great deal of difficulty has been encountered in the use of electric regulators'where there is encountered a considerable range in the supply voltage and in the load currents, and wherein it is required that there shall be close regul-ation.
One of the objects of the'present invention is to provide a regulator, the resistance of which may be reduced to a minimum When such reduction is desirable, and which will be stable in its Operation throughout a wide range of Operation.
A further object is to provide a regulator of the compressible pile type which will be satisfactory in Operation when the pressure is reduced on the pile, whereby pitting ofthe blocks will be prevented.
Further objects will be apparent as the description proceeds.
The one figure of the drawings represents diagrammatically one embodment of the present invention.
An el'ectromagnet is represented by .the
numeral 1. T his magnet may be connected across the circuit which it is desired to regu- The electro-magnetis provided with a pair of pole pieces 2, 3, which should preferably have faces' of arcuate Outline. Cooperating with the pole pieces 2, 3, is an armature 4, pivoted at the point 5. If desired, the armature 4 may be mounted on ball-bearings whereby friction Will be -re-. duced to a minimum. The point of pivotal connection 5 should preferably be midway' f havin between the pole pieces 2 and 3. The armature 4 should be provided With pole faces arcuate outlines to conform with the le aces of the pole tips 2-and 3.' The aces' of the magn-et pole pieces and the armature shouldpreferably be arcs of circles Two carbon piles 6, 6,1 are provided, which' are preferably inclined with-relation to eachr -other and to a horizontal line.
piles 6, 6, are provided with mlatively'fixed The carbon bWith the remainder of the regulator.
to P
abutments 7, 7. Appressure member 8, of wedge-shaped conformation, is adapted to coperate simultaneously withboth piles to compress them against the fixed abutments 7, 7. It will be apparent that as the pressure member 8 is moved. in an upward direction, as viewed in the drawing, such action will compress the carbon piles. When pressure is relieved on the pressure member, the blocks of the carbon pile will tend to Separate uniformly throughout the piles, though they Will never be entirely out of' contact. The pressure member 8 is connected to the armature 4 by means of a thrust member 9.
This thrust member 9 has pivotal connection with the pressure member 8 at the point 10 ture 4 will be normally held out of line with the pole pieces 2 and 3 by means of the spring 12, whose tension should be adjustable.
As will be apparent from the drawing, the Spring 12 Will urge the armature 4, and con sequently the thrust member 9, into a position to exert plressure upon the compressible piles 6, 6, wereby their resistance is reduced to a minimum. vInasmuch as the thrust member 9 exerts a toggle action, the
compressing effect-upon the piles 6, 6, may
be very considerable. The parts may. be So member 9 will compensate for the increasing mechanical resistance of the piles as their compression increases. be provided to damp the movement of the armature 4.
It will-be ,clear from the drawing that, in Operation, when the electro-magnet 1 is not excited to a.4 high value, the armature 4 Will be out of line with pole pieoes 2 and 3 and. the thrustmember 9 will exert a' maximum ggle effect to reduce the resistance of the i es 6, 6, to a minimum. As the energizaf vtio'n4 of the electro-magnet increases, the
armature 4 will be dragn into alinement` with the pole pieces 2,3, agamst the tension of the Spring 12, thereby withdrawing the designed that the toggle action of the thrust' A'dash-pot 13 may Wedge-shaped pressure member 8 and alloW- ing the blocks of the compressible piles to separate. By this action, the change of resistance throughout the piles Will be uniform, sparkin between the blocks will be eliminated, an pitting of the blocks Will be prevented. If desired, the regulator, according to the present invention, may be connected in series in the circuit to be regulated' through the abutments 7, 7.
It is not desired that the patent should be limited to the exact embodiment of the invention illustrated. Many modifications Will occur to those skilled -in the art. It is intended in this patent to cover all such modifications that come Within the scope of the invention as defined by the appended claims.
What I claim as new and desire to secure y by Letters Patent of the United States, is-
1. In combination, a pair of compressible piles inclined to each other and to a horizontal line, a Wedge-shaped pressure member adapted to press said piles upWardly to compress same, and a toggle member for Operating said pressure member.
2. In combination, a magnet having a pair of oppositely placed pol'e pieces, an armature p1votally mounted at a point between said pole pieces, a pair of compre'ssible piles inclined to each other, a Wedge-shaped compression member coperating With said piles, a thrust member having pivotal' connection With said compression member and said armature, the point of connection With said armature being difierent from the point of pivotal mounting of said armature.
3. In combination, a pair of compressible piles inclined to each other, a Wedge shaped pressure member coperating With said piles and a toggle member for Operating said pressure member.
4. In combination, an electromagnet having an arcuate pole face, a pivoted armature having an arcuate pole face, said pole faces having approximately the same center, which is the point of pivotal mounting of said armature, a toggle operated by said`armature, a Wedge operated by said toggle, and a compressible pile operated by said Wedge.
5. In combination, an electromagnet having an arcuate pole face, a pivoted armature having an arcuate pole face, said faces having approximately the same center which is the point of pivotal mounting of said armature, a toggle operated by said armature, a Wedge operated by said toggle, and a pair of compressible pilcs inolined to each other and to a horizontal line, said Wedge being adapted to simultaneously compress said piles by an upward movement.
In Witness Whereof, I have hereunto subscribed my name.
WILLIAM A. TURBAYNE.
