ELECTRICAL CONTROLLING DEVICE.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed. June 27, 1907. Serial No. 381,060.-
To all whom it may concern:
Be it known that 1, JOHN T. WHALEN, a citizen of the United States of America, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Electrical Controlling Devices, of which the following is a specification.
This invention relates to electrical controlling devices, and its object is to provide simple and reliable apparatus whereby the flow of liquid or gaseous fluids, in a conduit, may be readily regulated and controlled, automatically and from a distance, if desired.
In the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, are shown several ways of carrying invention into effect,
- but more particularly to how the same may be applied to internal combustion motors or engines for the purpose of throttling the gaseous fuel supply from the carburetor while on its way to the explosion chamber, as described in my application for Letters Patent in the United States, Serial N 0. 375,521.
Figure 1 is a side elevation of one form of my apparatus. Fig. 2 is a vertical, central cross section on line AA of Fig. 1. Fig. 3 is a horizontal, longitudinal central section on line BB of Fig. 1. Fig. 1 is a cross section of the damper on line OO of Fig. 3. Fig. 5 is a cross section on line DD of Fig. 3. Figs. 6 and 7 are elevations of opposite sides of a different form. Fig. 8 is a top elevation of the same, and Fig. 9 is avertical, central cross section on line E-E of Fig. 8.
My invention consists, mainly, of an oscillatory member, as avalve or a damper, which is mounted on a spindle in a conduit or connecting pipe for the passage of the fluid to be controlled, in such a manner as to reduce the area of the particular section of the said connecting pipe containing the said damper whenever an iron armature carried by the said spindle of the damper is attracted by its magnet. in reducing the area of a conduit at any one of its points a resistance to the flow of the fluid is created which increases as the area is decreased, interrupting the flow entirely when the damper is placed at right angles to the axis of the connecting ipe, or equivalent, provided the diameter of the damper is substantially the same as the inside diameter of the conduit or connecting pipe. I prefer to accomplish the operating of the damper and thereby the throttling of the fuel supply by degrees, progressively, that is, between the two extreme positions of the damper which, in one case, permit an unobstructed passage of the fluid, and in the other, prevent it altogether, I select a number of intermediate positions of the damper for, more or less, throttling the fuel supply, employing an electro-magnet or similar electric motor for each position or step, thus giving a step by step or progressive motion to the damper. 1 preferably arrange the poles of the armatures and magnet cores in such a manner that the action of the magnet which caused the preceding step brings the armature of the magnet for the following step intothe zone of effective attraction of the same. By zone of efiective attraction I mean, sub stantially, the maximum distance between a magnet and its armature at which the latter will still be attracted quickly.
Referring to the drawings, a is a section or part of a conduit or pipe connecting a car bureter with the cylinder of a gas engine which supports, on pivots Z) Z), or ball bearings, a spindle 0, preferably of square cross section, to which spindle are secured a damper d, iron armature c and spiral spring f. When the damper is in its position of rest, as shown in Figs. 1, 2 and 3, that is, when the same occupies a position with its plane parallel to the axis of the pipe, or to the flow of the fluid, the area of the passage is a maximum and the resistance to the flow a minimum. Spring f the inner end of which is secured to the spindle while its outer end is fastened to a convenient place on pipe to is tensioned so as to press the armature against the stop pin 9 on the said pipe, thereby maintaining the damper in its position of rest as long as the said iron armature is not energized. An iron core "J, preferably arranged to permanently make good magnetic contact with armature c at their middle, as shown in Figs. 2 and 3, is provided at its extremities with pole pieces i i and may be energized by two coils j j. This core is bent at its middle at an angle of about 135 degrees. As shown in Fig. 1, pole e of armature c is during the period of rest within the zone of effective attraction of pole shoe '6, therefore, if an electric current is sent through coil j the armature 0 will be turned or swung in the direction of the arrow, Fig. 1, and with it damper d, until the path of the magnetic flux becomes the shortest possible and of the least resistance, theoretically, which condition would exist as soon as armature e is parallel to coil j. The damper (2 will then be in a position at an angleof 45 degrees to the pipe and thus re duce the flow of the fluid correspondingly. Armature e in turning to place itself parallel to coil j, its pole 6 will thereby come within the zone of effective attraction of pole shoe 71; therefore, should subsequently an electric current be sent through coil j instead of through coil j as before, pole e of the armature will be attracted and the latter turned, together with the damper, until they are at right angles to the pipe a, damper d thereby entirely closing the pipe and interrupting the flow of the fluid. As soon as the electric current is turned off spring f will return armature e and damper d to their positions of rest.
It is obvious that with the arrangement of the magnets as shown armature a can only be attracted by pole piece 2' after the former had been brought by the action of pole piece i on pole e of the said armature within the zone of effective attraction of pole piece 11. Armature e and core i, according to the relative position of the former, thus provide two separate magnets, to be brought into use successively by sending an electric current first through coil 9 and then through coil j, for the purpose of obtaining a two-step motion of the armature in common and the damper. In practice, core i with its pole shoes t and i must be set somewhat in advance, that is, in the direction of the arrow, Fig. 1, to ermit of a longer reach to overcome friction and the resisting force of the spring, the angle of 135 degrees formed by the two halves of the core, however, remaining unchanged.
The form of my invention shown in Figs. 6 to 9, inclusive, differs from the one before described in that, instead. of a double magnet on one side of the pipe formed by a single core and a single armature, a single magnet is placed on each side of the conduit. Spindle c, which is in this construction shown to be supported by ball bearings and to which the damper d is fastened, carries at each end an iron armature, as e, 6, adapted to be attracted by the pole pieces of magnets i and 'i for the purpose, as before, of placing the damper in a position in Which the flow of the fluid may be reduced and subsequently entirely interrupted, as may be desirable. In this form of my apparatus each magnet acts upon both ends of its armature simultaneously, but only one magnet is to come into action at a time, as in the form first described, to move the damper through an are of about 45 degrees for each step, or of a total of about 90 degrees for the two steps provided for, from the position of rest to that at which the fuel supply to the engine is entirely interrupted.
In operating the last described form of my apparatus, armature e shown in Fig. 6 is attracted first and turns in the direction of the arrow, thereby turning the damper 45 degrees and bringing the armature on the opposite side of the pipe, as shown in Fig. 7, within the zone of effective attraction of its magnet poles so that as soon as the electric current is sent through its coil instead of through the coil first energized the armature may be attracted and thereby turn the damper until it closes the fuel supply pipe in a progressive manner as before described, each step having an increased effect on the fuel supply.
As other forms, changed to suit particular requirements, may be found equally advantageous and desirable in carrying my invention into effect, I do not wish to confine myself to the constructions and details shown, nor to a two-step motion of the damper, as I may prefer to employ three or more magnets to obtain three or more steps,
and I may choose to place the winding on any other part of the magnetic circuits provided for.
Having described my invention and in what manner the same may be made use of, what I claim as new and desire to secure by Letters Patent is:
1. The combination, of a fuel-supply conduit, and means for throttling the fuelsupply carrying an armature, of means for electro-magnetically, successively energizing the said armature to obtain a multiple-step motion, whereby the fuel-supply is throttled differently.
2. The combination, of a fuel-supply conduit, and means for throttling the fuelsupply carrying an armature, of means for electro-magnetically, successively energizing the said armature to obtain a multiple-step, progressive fuel-throttling motion.
3. The combination, of a fuel-supply conduit and a damper revolubly mounted therein on a spindle together with the armatures of electro-magnets, with means for successively energizing the said armatures to obtain a multiple-step throttling motion of the said damper. V
