SUPPORT FOR ELECTRICAL TAPS OR OUTLETS.

To all whom it may concern:

Be it known that I, JOSEPH SACHS, a c1t1 zen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certam new and useful Improvements in Supports for Electrical Taps or Outlets, of which the following is a specification.

The object of this invention is to produce a new and useful support for taps or outlets which are adapted to receive electrical fixtures of any kind, be it a light, attachment plug or other device.

Broadly considered, the invention comprises a magnetic base upon which current inlets and outlets or taps are mounted, to one of which an ordinary service supply circuit may be connected to supply current for the magnet and the other tap, the other tap being adapted to receive any kind of an electrical fixture.

The device is designed for use in connection with a suitable metallic supporting surface which forms the armature of the magnet.

In the drawings Figure 1 is a top view of one embodiment of the invention, part being broken away to show construction. Fig. 2 is a central vertical section on the line 2, 2 of Fig. 1. Fig. 3 is a central vertical section 011 the line 3, 3 of Fig. 2. Fig. 4 is a diagrammatic view of the circuits. Fig. 5 is a side elevation of a modification. Fig. 6 is a top view. Fig. 7 is a central vertical section on line 7, 7 of Fig. 6. Fig. 8 is a central vertical section on line 8, 8 of Fig. 6.

In the embodiment of the invention shown in Figs. 1 to 3, the structure comprises a base a of magnetic material provided with a suitable magnetic coil I), an ordinary snap switch indicated at c, (the detail structure not being illustrated), which controls the supply of current to the device, and a plurality of current outlets or taps either in the form of sockets d d of usual construction as illustrated, or of any other desired type. The switch 0 is operated by the usual spindle 1 extending down through the base and having at its end a turn button 2 positioned in a recess in the bottom of the base, so that when the device is in use, the turn button is concealed and inoperable. The circuit of the device illustrated extends from Specification of Letters Patent.

Application filed June 16, 1911.

Patented Oct. 21, 1913. Serial No. 633,632.

opposite one of the switch terminals 0'. Pressure on the button will move the arm into contact with the switch terminal short circuiting the coil b but leaving intact the circuit to the taped d. Of course, these circuits can be arranged in various ways, and I do not wish to be understood as limiting myself to the circuits here shown and described though it constitutes a simple method of wiring and is effective for the purposes in hand. It is generally desirable to so arrange these circuits, however, that the short circuiting of the magnet does not interfere with or break the supply of current to the taps. Another desirable feature of a device of this sort is to so locate the operating mechanism of the main supply controller, as the turn button of the switch illustrated, that it is inoperable when the device is in use. So long as it is necessary to cut-out the magnet and remove the device before the switch or other controller can be operated, there is little or no danger of the device falling; while if the turn button were not concealed, it might easily hap pen that the turning out of the lights and the consequent cutting out of the magnet would result in the device falling and pos sibly being considerably damaged.

Another form of device for rendering the operating handle of the controlling switch for the supply circuit inoperable is illustrated in Figs. 5 to 8. In this case as in the device illustrated in Figs. 1 to 3 the magnet is in series with the taps but the operating handle 10 of the switch is always exposed. In this case, the locking device comprises a longitudinally movable plunger 11 having an end exposed through the bottom of the base, the upper end of the plunger operating a stop-pin 12 to move it into engagement with a part, as the switch plate 13, attached to the spindle 14. It will be seen that when device is in use.

the device is in use, the switch plate is engaged by the pin which is held in this locking position by the plunger which is positioned by its contact with the supporting surface. The spindle is adapted for longitudinal movement to throw it into contact with the arm 16 short circuiting the magnet across the terminals of the coil and releasing the device from the support, thereby leaving the plunger and the locking pin free to drop, thus releasing the switch plate so that it can be turned by the handle. It must be obvious that there are many other ways in which the controller of the supply circuit, or its operating handle, can be ren dered inoperable while the apparatus is in use or the magnet energized. Such means may be provided which are electrically or magnetically as well as mechanically controlled, and I do not wish to be understood as limiting myself to either of the specific means herein illustrated and described for accomplishing this result. It will nevertheless be noted that in the embodiment illustrated in Figs. 1 to 3 the operating handle for the switch constitutes part of one of the poles of the magnet. Two advantages result from this construction. In the first place, being so arranged the operating handle is certainly and completely concealed while the In the second place the interposition of this handle as a part of the central pole piece constitutes what may be called a double break in the magnetic circuit of the base with the result that when 1 the magnet is short-circuited this double break operates to kill the residual magnetism 1 and affords a quick and ready release of 1 the device from its supporting surface which constitutes the armature of the magnet. I also desire to call attention to the fact that the two taps shown are interchangeable. That is to say, either one may be used as an inlet tap to supply current to the device and the other as the outlet tap in which is mounted a fixture of any sort, as a lamp. Furthermore, that these two taps are arranged at an angle to one another and preferably that one tap is arranged centrally of the base and the other at an angle thereto.

There are various other modifications and alterations in the general structure and in its detail of construction and operation of which the invention is susceptible, and it should be clearly understood that the embodiments of the invention which I have selected for illustration are merely characteristic of their own classes and are not intended as illustrations of all forms which the invention mi ht take.

It is my intention to include herein and in the appended claims any and all modifications of the broad and specific aspects of the invention which come within the spirit of the invention.
