CURRENT-CONTROLLING DEVICE.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed April 17, 1911. Serial No. 621,590.

To all whom it may concern:

Be it known that I, LEON O CORELL, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Current-Controlling Devices, of whichthe following is a specification.

This invention relates to improvements 1n circuit controlling devices.

- The main objects ofthis inventionare: First; to provide an improved circuit controlling device for lamps or other circuits, which enables the opening or closin of the circuits from an desired number 0 points.

Second; toprovide an improved controlling device for electrical circuits controlled by an electromagnet in which the circuit is closed on one energizing of the magnet and opened on the succeeding energizing of the magnet. Third; to provide an improved control device for electrical circuits which enables the opening or closing or the circuits from a plurality of points with a minimum amount of wiring. Fourth; to provide an improved device of the class described which is very compact in structure and not likely to et out of repair or to become inoperative. Figh; to provlde an improved control device of the class described which may be operated by simple forms of control switches. Sixth; to provide an improved device of the class described in which the devices may be arranged and connected in series. Seventh; to provide in a device of the class described an improved casing.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention 40 by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A-structure which is a preferred embodiment ofmy invention is clearly illustrated in the accompanying drawin forming a part of this specification, in w ich:

F i re I is a plan view of a structure cmbodymg the features of my invention with the cover removed. Fig. II is a detail view of a pair of the devices one being superimposed upon the-other, the upper device being shown mainly in vertical section taken on a line corresponding to line 22 of Fig. I. Fig. III is a vertical section taken on a line corresponding toline 33 of Fig. I. Fig. IV is a perspective view of the armature and contact member 22 removed from the casing. Fig. V is an inverted perspective view of the control member 29. Fig. VI is a diagrammatic view showing a series of the devices and their Wiring.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the casing and 2 the cover thereof. The casing is provided with flanges 3 on its bottom, so that when the casings are arran ed in series as shown in Fig. II the superimppsed casing serves as a cover for the casing low. The casing is provided at its upper end with cover engaging flanges 4. The

casing is preferably formed of porcelain, although other suitable insulating material might obviously be used. Or if desired the casing might be formed of any material and the parts arranged therein suitably insulated.

Within the casing I arran e an electro magnet 5. This is supported y the bracket 6 which in the structure illustrated is secured by the screw 7 arranged through the bottom of the casing. The armature 8- is mounted on the pivot 9, carried by the bracket 10. This bracket is in the structure illustrated secured by the screw 11 arranged through the bottom of the casing. These brackets are seated in the bottom of the casing as shown in Fig. II. Above the magnet I arrange a pair of circuit or terminal members 12,'the rear wall of the casing being Ei-ovided with seats 13 in which the memrs 12 are clamped by means of the screws 14 and the terminal members 16. The screws 14 are arranged in holes 15 provided therefor inthe wall of the casing, to engage the terminal members 16. (See Fig. III). At the rear of one of these seats. the wall of the casing is provided with a vertical hole 17 through which the line wire 18 is passed. This wire is connected to the terminal member 16 by means of the bindingscrew 19. When the devices are arranged in series as illustrated these holes 17 are in alinemcnt and the line wire is extended through them all. The controlled circuitwire 20 is connected to the other terminal member as 11:

shown in Fig. T. The wall is provided with a recess 22 for the wire 20.

Coacting with the circuit or terminal members 12 is a contact member 21, which is in the structure illustrated, mounted on the armature pivot 9 between the armature and the coils. With the parts in their open or normal position on the energizing of the magnet, the contact member 21 is closed. 011 the succeeding energizing of the magnet the circuit is broken and the contact member returned to its open position. I will now describe the means by which this is accomplished. i

The contact member 21 is provided With rearwardly projecting downwardly inclined flange-like keeper members 23, which when the contact member is closed are engaged by the oifsetlike catches 24 on the ends of the circuit members 12, so that the contact member is retained in its closed position. The armature is provided with a release member 25, which is pivoted at 26 on the rearwardly projecting arm 27 on the upper end of the armature. This release member is provided with a contact member catch 28. The arm 27 limits the downward movement of the release member on its pivot. A control member 29 is provided to coact with this release. The rear end of this control member is arranged in a seat 30 provided therefor in the rear wall of the casing, its forward end resting upon the contact 21. At its forward end the control member 29 is provided with flange like cams 31 which ride up on the contact member as it is closed, so that the control member is raised and retained in its raised or actuated position when the contact member is in its closed position. (See Fig. MT.) The control member is provided with stops 32 for the contact member and with rests 33 at the rear ends of the cams 31. The flange-like cams 31 also serve as guides forthe release member as it passes between them on the circuit opening actuation of the magnet. The control member is provided with a plate 34 of insulating material, which projects under the circuit members 12 so that when the control member is elevated the forward ends of the circuit members are raised. Vl'hcn the control member is in its normal position as shown in Figs. T and H and the armature actuated, the release mem ber 25 passes over the control member and is thereby disengaged from the contact member, the contact member being engaged by the circuit members is retained in its closed position so that upon the deenergizing of the magnet the armature returns to its initial position, leaving the contact member in its closed position. 'l pon the rei nergizing of the magnet with the parts in this position, the control member is raised by the release member 25 as shown in Fig. HI, to break the circuit by separating the circuit and contact members and the release member is engaged with the contact member so that. on the deenergizing of the magnet the contact member is carried back to its open position. This completes the cycle of movement. It will be noted that the circuit is broken upon the second energizing of the magnet. This is of advantage as it is very desirable to have it broken at this point' rather than on the second denergizing of the magnet. Further a quick break of the circuit is secured, which prevents arcing. Whenthe armature is in its open position, the rear flattened end 43 ot the member 25 rests against the Wall of the casin which holds the release member downwar ly upon its supporting arm 27, as is shown in Fig. Ill.

The battery circuit wires are connected to the magnet coils through the wires 36 which are arranged in passages 37 in the walls of the casing and connected by the screws 38 to the terminal members 39. The switch wires 40 are arranged in similarpassages. These passages open through the bottom of the casing for convenience in assembling parts with the connections. Thus arranged it is quite impossible for them to" short circuit and the devices may be Very easily put into the system.

In Fig. Vii T illustrate diagrammatically a series of the devices, each device being provided with a pair of switches 41. These are shown in conventional form. It is obvious that they may be placed in any desired position. I illustrate a battery 42 as a source of supply for operating the magnets. Any suitable source of supply may be used. This arrangement of parts reduces the amount of wiring to a minimum and the control switches may be of any form, a. single push button switch serving to turn on or off the circuit, one closing of the switch will close the circuit controlled and the succeeding closing of the switch will open the circuit.

My improvements are especially designed by me for use in electric lighting systems, as they enable the control of the lamps from as many points as may be desired. The control switches l1 may be placed in any position for convenient manipulation and as. a single switch or push button answers the purpose. the same can be placed in the floor or in any convenient position to be actuated by the foot as no selection of buttons for opening or closing is required.

While the particular form illustrated has numerous advantages, 1 am aware that considerable variation in structural details are possible without departing from my invention, but as such variations will no doubt be readily understood by those skilled in the art to which this invention relates. i have not attempted to illustrate or describe the same herein.
