Patented June 7, 1932 UNITED STATES PATENT OFFICE ANDREW .1. sonnNsmr, or rmaavaon, PENNSYLVANIA, assrexon r nu: UNION SWITCH a SIGNAL COMPANY, or swxssvam, PENNSYLVANIA, acoaronarron or PENNSYLVANIA ELECTRICAL MELATING APPARATUS Application Med December 8, 1980. Serial Io. 500,508.
My invention relates to electrical translating apparatus, and particularly to apparatus of the type comprising an output circuit furnishing current to a load, and a control Tcircuit for determining whether or not the efl'ectively energize the load.
I will describe one form of apparatus embodying my invention, and will then point out the novel features thereof in claims.
The accompanying drawing is a View, partly in elevation and partly diagrammatic,
' showing one form of apparatus embodying my invention. a
Referring to the drawing, the apparatus involves a transformer T, comprising three cores A, A and B of magnetizable material. Core A comprises three parallel legs 1, 2 and 3 connected by members 14 and 15. The construction of core A is similar to that of core A The core B comprises three parallel legs 11, 12 and 13, which legs are connected by members 16 and 17. The cores are so positioned with relation to each other, that the legs 3 of cores A and A are located on opposite sides of the middle leg 12 of core B.
Surrounding the legs 3 of cores A and A and the leg 12 of core B is a primary winding 4, which is constantly supplied with alternating current from a suitable source,
such as a generator G. The leg 12 of the core B is provided with an output winding 6, which is constantly connected with a load 7. As here shown, this load is an electric -'lamp. The-middle leg 2 of the core A is provided with a control winding 8, and the middle leg of the core A is provided with another control winding which is made up'of two sections 8 and 8". The control winding 8 is connected with a source of direct cur rent O through a circuit controller 10. Section 8 of the second control winding isconnected with another source of direct current C through a circuit controller 9. The other section 8 of the second control winding is supplied with direct current from the output winding 6 through a rectifier R. a
The middle leg 2 of each core A and A if is preferably provided with a sleeve of electro-conductive material to prevent alternating current in winding! from'inducin currents in the control windings 8, 8' a'n The operation of the apparatus is as fol lows: When the control winding 8 is deenergized, the permeability of core A is relatively high, and flux due to current in the; primary winding 4 can flow freely through 13 this core, so that little or no flux from the primary winding will pass through the output winding 6, with the result that the current supplied to the load 7 will be insuflicient to effectively energize the load. Similarly, 7b
when both windings 8 and 8 are deenergized, the permeability of the core A is relatively high, so that little or no flux from the primary winding 4 will pass through the output winding 6. If, however, control winding 8 and either section 8 or 8 of the other control winding are energized, the permeability of both cores A and A is decreased, and flux from the primary winding 4 is then forced through the output winding 6, with the result that the load 7 will be effectively energized. i i Assuming now that circuit controller 9 is 1 open, and that circuit controller 10 has been opened and is again closed, it will be obvious is that the load 7 will be deenergized, because both sections 8 and 8 of the second control a winding are deenergized. If circuit controller 9 is now closed momentarily, control winding'. section 8 will be energized, thereby 25 1. In combination,
causing the output winding 6 to become energized, and this winding will then supply direct current to the control winding section 8 through rectifier R. Circuit controller 9 may 5 then be opened, but the output winding 6 and the load 7 will continue to be energized as long as circuit controller remains closed. When the latter circuit controller is opened, the load 7 will become deenergized and will remain deenergized until circuit controllers 9 and 10 are again simultaneously closed.
It follows from the foregoing, that in accordance with my invention an amplifying transformer may be used to perform the functions of the well known stick relay.
Although I have herein shown and described only one form of apparatus embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.
Having thus described my invention, what I claim is:
three magnetizable cores each having three legs connected in parallel, a primary supplied with alternating current and embracing the middle leg of the first core and an end leg of each of the other cores, an output winding on the middle leg of the first core, a direct current control wlndin on the middle leg of the second core,
means or controlling the circuit of said control winding, a second control winding located on the middle leg of the third core and comprising two sections, means for at times supplying one of said sections with direct current, and means including a rectifier for supplying the other section with direct current from said output winding.
- 2. In combination, a transformer having a primary winding connected with a source of alternating current, an output winding inductively related to said primary winding and connected with a load, a direct current first control winding, means for controllin the circuit of said control winding, a secon control winding made up of two sections, means for at times supplying oneof said sections with direct current, means for supplying the other section with direct current from said output winding throu h a rectifier, and means for preventing su cient flux due to current in said primary winding from passing through said output winding to effectively energize said load unless said first control winding and one section or the other of said second control winding are energized.
3. In combination, a transformer having a primary winding connected with a source of alternating current, an output winding inductively related to said primary winding and connected with a load, a control winding made up of two sections, means for at times supplying one of said sections with direct All; A
