Specification of Letters Patent.

Patented Feb. 20, 191,2.

Application led May 7, 1909. Serial No. 494,575.

To all whom it may concern:

Be it known that I, WILLIAM P. CAR- s'rARrHF-N, J r., a citizen of the United States, Vresiding in the city and county of Denver 5 and State of Colorado, have invented certain new and useful Improvements in Switch and Cut-Out Boxes; and I do declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which j it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in a box adapted to contain fuse blocks or .other electrical apparatus normally concealed, but which must be accessible at times for repair or other purposes. Boxes of this character are usually set in a recess formed in the wall of the room where they are lo-4 cated and the object of my present invention is to conceal the roughetlges of the wall surrounding the said recess; and to this end I provide a cover forthe box' of such character that its outer edge projects beyond the body ofthe box on all sides and, thus conceals the opening when the lid of 430 the box is closed. In order that this projection of the cover or lid, on the hinged side of the box may be practicable, a special hinge construction vis required. It is evident that if this lid were hinged in the ordinary way, the projecting edge would dig intogthe wall during the opening movement of the lid and form a recess for the entrance of the said projecting edge, unless the wall were sufficiently solid to prevent such oper- 40 ation, in which last named event, the lid could not be opened.

Having briefly outlined my imporoved construction, I will proceed to descri e the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.-

In' this drawing, Figure 1 is aV section taken through my improved box cutting the wall in which the box is set. Fig. 2 is a front view of the same with the lid in the closed position.

The same characters indicate the same parts in all the views. l

Let the numeral 5 designate a box having a bottom 6, a'lsurrounding wall 7 and a lid 55 8. This lid projects beyond the body of the box on all sides and its projecting part 9 on'the hinged side, is provided with a v flat hinge member 10 formed into an eye 12 registering wit-h an eye 13 formed in a 60 hinge member 15 having parts 16 and 17 extending at right angles to each other, thepart 17 being secured to the vertical wall of the box as shown at 18, while'the'part 16 projects outwardly from the box to the eye 13. As shown in the drawing,^the lid is connected with the box by two hinges of the. character just described. y

As illustrated. 'n the drawing a number of devices 19 are shown located within the 70 bo'x simply for the purpose of illustrating the function of the latter. It may be as- 'sumed that these devices are fuse blocks. From each extremity of each of these blocks leads a pair of wires or conductors 20 which 75 pass out of the box and extend therefrom through a tube 21.' As these features are not a part of my invention, they will not be further described in detail.

From the foregoing description, the use of my improved box will be readily understood.

The recess in.which the box is located is designated A, and the ragged edge ofthe vwall around the recess is designated B.

.The object of the lid as heretofore described, is to conceal 'the raggededge B, as illustrated in Figs. 1 and 2 of the drawing.

Having thus described my invention, what I claim is:

In combinatioma box for concealing electrical devices, the said box 'being set in a recess formed in a wall so that its outer edges shall be flush with the, surface of the said wall, a lid applied to the said box and pro* 95 jecting beyond the edges thereof on all sides far enough to cover the rough edges of the wall, the body of the box 'having a` right angle bracket, one member 'of the bracket y being secured to the wall of the box on one side, and the other member projecting beyond the same, iush with the outer surface of the wall to fo'm a hinge member., the lid having a cooperating hinge member, the axis of the hinge being located just beyond the projecting port-ion of the lid and extending parallel Vwith the Wall and just outside the Said Well, whereby as the lid swings outwardlyirom the plane of the Wall during its opening. movement, its projecting poi'- tion, on the hinge side, swings 'x'ee of the Wall, substantially as desc'bed. l ln testimony whereof l' aiix my signature in presence of two Witnesses.
