CLARENCE M. SIEFFERT, 0F EVANSVILLE, INDIANA, ASSIGNOR TO SIEFFER'I ELECTRIC COMPANY, OF EVANSVILLE, INDIANA, A CORPORATION OF INDIANA.

SWITCH-BOX.

Application filed December 5, 1916.

To all whom it may concern Be it known that I, CLARENCE M. SIEFFERT, a citizen of the United States, and a resident of Evansville, in the county of Vanderburg and State of Indiana, have invented a certain new and useful Improvement in Switch- Boxes, of which the following is a specification.

My invention relates to improvements in switch boxes, for electrical wiring systems, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a box which can be installed in new work much more quickly and at much less expense than ordinary switch boxes.

A further object of my invention is to provide a switch box having means for permitting its quick and economical installa tion, but which can also be adapted for ready installation in old work as well as new.

A further object of my invention is to provide a device of the type described which is simple in construction, and therefore cheap to manufacture.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming a part of this specification, in which:

Figure l is a plan View of the box showing it in position to be secured to a stud;

F'g. 2 is a side view of the box;

Fig. 3 is a rear view of the box, and

F ig. 4; is a section along the line 4.t

of Fig. 2.

In carrying out my invention, I make use of a metal box preferably cast iron or steel, of the general shape shown in the drawing. This box consists of a casing 1 having lugs 2 at opposite ends by means of which the casing may be attached to the studding, as will be explained, the rear part of the casing being beveled at the corners, as shown at 3, these beveled portions being provided with lugs 4 which are surrounded by scored lines 5 where the metal is relatively thin, so that a sharp blow on the lug will fracture the thin portions, thereby leaving circular openings for the admission of Specification of Letters .Patent.

the wires, conduits, or cables which are designed to enter the box.

As will be seen from Fig. 8, the sides of the ears or lugs 2 are flush with the sides of the casing 1. At the top and bottom of the casing is a cut-away portion 6. A hole 7 extends from the cutaway portion through the adjacent side of the box. In order that the box may have a firm bearing on the stud, the sides through which the holes 7 extend are slightly dished as shown at 11.

From the foregoing description of the various parts of the device, the operation thereof will be readily understood.

Ordinarily the switch boxes are secured to the studs by means of the ears, such as those shown at 2, and this generally necessitates the use of extra braces between the adjacent studs. The time consumed in the installation of these extra supporting devices is quite considerable. In the present instance, all that is necessary is to drive an eightpenny nail, such as that shown at 8, or to insert a screw in each of the openings 7, and to fasten the box directly to the side of the stud 9 in the position shown in Fig. 1. This eliminates fully three-fourths of the work required to secure the box in position. This means of securing the box insures its permanency and rigidity, and, as stated above, greatly expedites the labor of installation.

In view of the fact that the box is symmetrical as to its top and bottom, it can of course be reversed so as to be placed on either side of the stud, and this again is another advantage.

The box has the added convenience that, while it is primarily designed for new work, it has the lugs 2 so that in old work where the supports are already in place, the box may be fastened directly to the supports by means of the lugs 2. No change whatever is required in fastening the box, either by the use of the lugs 2 or the openings 7, and the presence of either does not interfere with the operation of the other.

I claim 2-- l. A switch box comprising a casing having symmetrical end portions, said end portions having recesses near one of the sides of the casing, and being provided with bores extending from the recesses through the tions having recesses near one of the sides adjacent side, said bores being angulariy of the casing, and being provided with bores l disposed with respect to one another, and reextendin from the recesses through the adtaining lugs carried by the end ortions and jacent side, said bores being angularly dis- 5 being provided with openings or receiving posed with respect to one another, said Sides the retaining members. being dished to provide a rigid bearing for 2. A switch box comprising a casing havsaid box near the ends thereof.

ing symmetrical end portions, said endpor- CLARENCE M. SIEFFERT.
