' in Wall-Boxes for Electric Switches, fully described and represented in the following speciiication and the accompanying drawings,

forming a part of the same.

This invention relates to a particular construction for a wall-box to retain an electric switch within a wall, and which being commonly placed in position during the earlier stages of the construction of a building is rarely set plumb and parallel with the walls. After the insertion of the switch the faceplate is often found to be out of plumb and not fitting against the plaster. l l

' The objects of this invention are, first, to

provide means for correcting the position of the axis of the face-plate, and, second, to provide means for adjusting the plane of the faceplate to the-plane of the wall. I attain these objects by means of the devices illustrated in the accompanying drawings, in which- Figure 1 is a top view of the switch-case with the switch mechanism removed. i Fig. 2

is a sectional View of the switch-case, in whichk lis the body of the case,and 2 is the back cover of the case. Fig.4 3 is a topview of the lugpiece. Fig. 4 is a front view of a wall-box with the face-plate and switch mechanism removed. Fig; 5 is a sectional View Of a wallbox with the switch mechanism removed. Fig. 6 is a detail showing the attachment of the lug-piece to the switch-case and the faceplate to the lug-piece. Fig. 7 is a view of the lug-piece 9 struck from sheet metal, one end being indicated'in section to show the method of forming the bevel in the slot to receive the head ofthe. clamping-screw 2l. Figs. 8 and 9 are front views of wall boxes with the switches and switch-cases removed, showingthe Wall-boxes shown in Figs. 8 and 9, respectively, and have portions of the covers broken away to show the slot and screwin section bearing against the surface of the wall-box. Fig. 12 is a sectional view of a wall-box, showing. a switch-case in position with a circuitcontrolling device in the switch-case.

The switch-case (shown in plan or top view in Fig. 1 and in section in Fig. 2) is formed of insulating material, and consists of a body 1 with a back cover 2 and is formed to receive the switch mechanism,which has been omitted in the drawings for the sake of clearness. The body 1 is perforated by the holes-3, 4, 5, 6, and 7, for purposes to be described and recessed at 8 to receive the lug-piece 9, (see Fig. 3,) while the sides and ends are tapered to permit of a partial rotation of said body 1 when placed in a wall-box, as shown in Fig. 4. The lug-piece 9 is 4secured to the body 1 by the screws 10, passing from the rear side through the holes 7 in the body 1. (See Figs. 5 and 6.) The holes 3 are formed to allow the conducting-wires to enter the switch-case. Holes 4, are shown in the case in Fig. 1 and are employed to permit the passage of screws 11, which are shown in Fig. 4, to hold the foot of a binding-post upon the body 1. The bindingpost rnay be Of an y ordinary construction and is merely indicated by the circle 12 in Fig. 4 to show its location. Around the rear of the body 1 is formed the rabbet 13 to receive the lip 111 of the back cover 2, as shown in Fig. 2. The lug-piece 9, pierced by the

holes

15 and 16, as will be seen in Fig. 3, is formed with the slotted ends 17, containing the slots 18. The holes 15 are threaded to receive the screws 10, while the holes 16 are threaded to receive the screws 19, which secure the faceplate 20 to the lug-piece 9. (See Fig. 6.)

The slots 18, which are formed on the arc of n a circle whose diameter is the distance from slot to slot have their edges beveled to receive the heads of the screws 21, which t into threaded holes in the cover 22 of the wall ff IOO 'the screws 2G, (see Figs. 1 and 4,) which fit in threaded holes in the yoke-piece 27 (shown in Fig. and secure the yoke-piece 27 to the body 1. Through the holes 6 in the body l are passed the leveling-screws 28, (shown in Figs. 4 and 5,) which iit in threaded holes in the yoke-piece 27. The ends 29 of the leveling-screws 28 are furnished with insulatingcaps 30. (See Figs. 5 and 12.) The back cover 2 is perforated with holes 31 to permit the passage of leveling-screws 28 and the hole 32, through which is passed the screw 33, fitted to a threaded hole in the yoke-piece 27. The screw 33 thus holds the back cover 2 to the body 1.

In Fig. 12 is shown a wall-box in position in the wall, with the protective tubes 34 entering each end and the insulated conducting-wire Slleading from the protective tubes through the back cover 2 to the circuit-controlling devices placed within the switch-case l, the circuit-controliing devices (indicated by the broken and dotted lines) being controlled by the push-buttons 36.

Having described the several parts of my invention, it will be seen that where a wallbox has been placed with its axis at variance with their proper position, causing the sides of the face-plate to stand out of plumb, such displacement may be corrected by loosening the screws 2l and turning the lug-piece 9 and switch-case 1 and 2 to the desired position or until the guide-lines 25 are plumb, when the lug-piece is clamped by tightening the screws 21. Should the wall-box have been placed so as to cause the plane of the face-plate to incline to the plane of the plaster, as shown by the position of the wall-box 23 in Fig. 5, the face-plate may be brought parallel to the plane of the plaster by removing the faceplate, loosening the screws 2l, and turning the leveling-screws 28 until the insulatingcaps 30 press ou the back of the wall-box 23 and bring the top of the lug-piece 9 flush with the plane of the plaster. The lug-piece may then be secured by tightening the screws 2l. The face-plate when replaced will be parallel with the plane of the plaster.

It is manifest that the precise details of construction I have described and shown may be varied without departing from the spirit of my invention, and I do not wish the invention therefore to be understood as restricted to such details. I have therefore illustrated modifications, showing in Fig. 7 the lug-piece 9 struck from sheet metal and the bevel of the slot 1S formed by depressing its edges to receive the countersunk head of the screw 21, which forms a ridge upon the back of the lugpiece. Figs. 8 to l1, inclusive, be formed with the slots and screws to permit the same adjustments which are provided with the prior constructions. In Figs. 8 and 10 the slots 18 are formed at the opposite ends of the cover 22 and the leveling-screws 27 are iitted through threaded holes at opposite sides of the cover and bear against the surface of the wall-box 23. In Figs. 9 and 11 the slots are made in the side portions of the cover and the leveling-screws are inserted in the ends of the same. All the constructions described perform the same functions as the lugpiece.

It is obvious that any suitable support or base adapted to be set in the wall would be an equivalent for the wall-box and any circuitcontrolling devices mounted thereon would be equivalent to the switch shown herein, and I have therefore made a broad claim to a cover or cover-plate with means whereby an angular adjustment may be effected between such cover and the base which supports the circuit-controlling devices.

Having thus set forth the nature of the invention, what is claimed herein is- 1. The combination, with a suitable support or base adapted to be set in a wall or other similar structure, of circuit-controlling devices mounted thereon, a cover-plate, and means whereby an angular adjustment may be eiected between the cover-plate and the base.
