9 Claims.
The invention embraces the provision of an electro magnetic means of very compact size and of simple construction adapted to control devices which indicate the effectiveness of a circuit of which the means forms a part. The invention comprehends the provision of electro-magnetic switching means so constructed as to occupy a minimum space and which is adapated to be incorporated in a wiring harness on an automobile for example, without the necessity of providing additional supporting means therefor.
Another object of the invention is the provision of an electro-magnetic switching device for controlling a tell-tale means, the device forming a unitary structure housing all the operating parts and being so arranged as to be readily inserted or applied to an established circuit or wiring harness without the necessity of making material changes.
Further objects and advantages are within the scope of this invention such as relate to the arrangement, operation and function of the related elements of the structure, to various details of construction and to combinations of parts, elements per se, and to economies of manufacture and numerous other features as will be apparent from a consideration of the specification and drawing of a form of the invention, Which may be preferred, in which:
Figure I is a top plan view with the housing in section;
Figure II is a cross sectional view of Figure I and showing one form of electro-responsive switching means;
Figure III is a side elevational view of the device illustrated in Figure I with the housing shown in section;
Figure IV is a diagram of one type of installation of my device.
The drawings illustrate the principles of the invention and their application to a signalling system for vehicles wherein the relay is carried by the electrical wiring itself, but it is to be understood that the invention is not limitedto the particular form or systems shown, but that the same or the component features are susceptible of many variations. Thus, in Figure IV, I show battery I as a source of electric energy, a battery lead 2 extending to the relay indicated at I0. From the relay II), a signal light lead 4 connects with manual switch 5, lead 6, to a lamp 'I, both lamp and battery being grounded as indicated. One use of my relay is to illuminate a pilot light 8 if lamp 'I is operating properly and hence pilot lamp 8 is also connected by lead 9 to relay I0 as shown.
Divided and this application May 29,
Referring now to Figures I and III, the relay IU has a stationary contact II which is adapted to be engaged by a movable contact I2 carried by the pivoted armature I4, and these contacts are normally retained out of engagement by a spring I5. rEhe armature I4 is connected by the conductor I'I to the battery lead 2 for establishing a, secondary circuit between the battery and the tell-tale lamp 8 when the contacts II and I2 are in engagement due to the energization of winding I3 of the relay I0".
The electro-responsive switching means or relay I0 of the invention is of very compact size, of great simplicity and so constructed that the same can be readily incorporated at any point of the main working circuit, the condition of which is to be indicated by any tell-tale means, Without the necessity of providing separate supporting means thereof. One form of construction embodying these features is shown in Figures I and II, and the same includes a circular Voutside tube or casing 2G having a substantially rectangular brass channel plate 2| for carrying the Ycoil I9 and parts of the relay. BatteryV lead 2 is connected with an offset arm 24 supported on the base of channel 2|, lead 2 being connected with the coil I9 of the relay by connecting lead 25. The other end of coil I9 is connected by lead 2l to main lamp circuit lead 4, switch 5 to lamp '1.
The relay coil I9 has a central core piece 28, with an L-shaped end 29 adapted to attract armature I4 against the action of spring I5. It will be noted that the coil I9 is very compactly wound.
The pilot light 8 is connected by lead 9 to sta# tionary contact I I by an offset struck up terminal piece 30.
This terminal 3G is insulatingly supported by the channel shaped base member 2 I.
The movable contact I2 carried by arm I4 and spring I5, as stated above, extends longitudinally along the bottom of the channel 2| and it is secured at 33 to the channel base, the member I4 being centrally located thereof as shown in Figure I, and the terminal 33 is connected by the offset arm 24 of conductive material to be connected to the battery input lead 2. In order to insulate satuisfactorily between the input lead 2 and the lamp lead 4 I provide an insulating wall 35 between these two terminals as shown.
In order to adequately anchor the several parts to the bottom of the channel 2l as indicated above, and at the same time insulate the same from the Walls or channels of the member 2l as well as from the tube or housing 20, I provide a pair of insulating strips 35 and 3l, one on the bottom side of the channel 2l vand the other on the top side thereof as shown in Figures II and III. It will be understood that the openings in the base of the channel 2i for receiving any anchoring rivets should be made larger than the rivets whereas the opening through these two insulating pieces 36 and 3l will more securely t the rivets in this way insuring good insulation between the pivots and the base of the channel 2 l.
