H A. FISHER. ELEGTRIG SAFETY BOX.
APPLICATION FILED SEPT. 30, 1908.
r 944,605. Patented Dec.28,1909.
Zdz'ln esses. I Jiwenl0r '1 Km/v7 YUNITEDSTATEs PATENT; orrion HARRY A. risnna, orr AINvILLE, CONNECTICUT, ASSIGNORYTO- TRUMIBULLI anno- TRIC MANUFACTURING COMPANY, OF PLAINVILLE, CONNECTICUT, A. CORPORA- 'IION OF CONNECTICUT.
a device of the class specified which has fealures of novelty and advantage.
Figure 1. is a perspective view of the box; Fig. 2. shows an enlarged view of a side of the box withthe shutters closed. Fig. 3. shows an enlarged view of a side of the box with the shutters arranged for the smallest circular opening. Fig. 4;. illustrating one of theshutters shows the cross-slots.
Referring to the drawingsthe side a-- of the box has an original opening as at -I preferably circular, intowhich conduit-pipes carrying the main wires are to'be fitted. The size of these conduit-pipes varies and it is often necessary to drill larger holes or replace a whole side having a smaller hole in order that the pipes may fit snugly, thus n'eventing any danger of fire toadjoining inflammable material. This is always cause for delay as well as being expensive.
On each side of the original opening -b- I' provide shutters -c0- which are centrally pierced and preferably by means of screws are secured tight against the side of the box. These shutters are both of the same shape each having one straight-edged side On the other edges I provide as at (Z. a number of sem1-c1rcnlai'.cuts as at eeof various diameters. I also prefer to have the shutters cross-slotted as at f-' so that the shutters ma y be moved either vertically or horizontally.
The operation of the device is as follows:
The conduit-pipes are usually in place before the box, and as the pipes are apt to be of most any size I select the semi-circular cut in the shutters that fits the pipe,'andatter loosening both screws sufficient to. allow the shutters, when revolved,- to overlap each.
Specification of Letters Patent.

ELECTRIC SAFETY-BOX. Y
Patented Dec. 28, 1909. I
semi-circular cuts in the shuttersmay be. matched up. 1. i.
' As the pipe might not come in. the centerv of the original opening -b, by means of the cross-slots ffboth shutters may be moved vertically or horizontally till the new opening is in the desired alinement.
It is often times an hdvantage tohave a number of original openings in the sides of the box, and if any of the openings are not needed the straight-edged sides of the shutters are arranged touching each other so that the opening is entirely closed.
. The boxes themselves may be of any noninflammatory material and maybe large or small according to the size of the electrical apparatus to be located therein.
I claim: i 1. In an electric safety-box, a side of said box having an openingtherein, two shutters pivotally secured to the side of said bo'x on opposite s des of said opening, each shutter having a plurality of semi-circular cuts, means for arranging said shutters whereby the opposite corresponding cuts therein prooriginal opening in the side of said box.
2. In arm-electric safety-box, a side of said box having an opening therein, two shutters pivotally secured to the side of said box on opposite sides of said opening, ea'ch shutter having a numerality of various sized semi-circular cuts,-saidsemi-circular cuts of one shutter corresponding with thesemi-circular cuts of the opposite shutter, means for adjustably securing the opposite shutters so that the corresponding semi-circular cuts will face each other whereby a circular open ing of smaller size than the original opening is provided in the side of said box.
3. In an electric safety-box, a s' e of-said box having an opening therein, two shutters pivotally secured adjacent said opening, said shutters being centrally cross-slotted whereby they may be moved vertically pr horizontally, each shutter having a numerality of semi-circular cuts on' their outer edges, and means for adjustably securing said shutters whereby the desired size of a circular opening smaller than the original opening may be provided in the side of said box." J I 4. In anelectric safety-box, a side of said. box having aniopening therein, two shut-v fters pivotally mounted and secured to the *vide a circular opening smaller-than the side of said box on opposite sides of said openin each of said shutters having one straig t-edged side adapted to face each other and close said original opening and a numerality of various sized semi-circular cuts near their other edges whereby said original opening in the side of said box may be either entirely closed or changed to a circular opening of a desired size smaller than said original opening in the side of said box substantially as described.
5.- In an electric safety box, a side of said box having an opening therein, two shutters; rotatably secured to the side of said box on opposite sides of said opening, each of 15 HARRY A. FISHER.
