CONTAINER FOR ELECTRIC WIRES.

To all whom it may concern:

Be it known that I, HYMAN Or-IARM, a citizen of the United States of America,

and a resident of Dorchester, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Containers for Electric Wires, of which the following is a specification.

This invention relates to wire-containing strips adapted to be used in wiring buildings and has for its object theprovlsion' of a device of this character which may be assembled readily and in which the various compartments are each of a size to receive a single insulated wire such as is in general use in wiring buildings.

A further object of the invention is to provide a containing strip which will be ornamental when installed and in which the usual coverplate is dispensed with.

The invention consists primarily of a two-.

part container the body part having two parallel compartments each adapted to receive a single wire whileothe other part is adapted to be frictionally retained between the portions of the body part in which said compartments are located.

The invention further consists of long strips of sheet metal having their opposite edges bent over to form two parallel but separated cylindrical portions each having a bore,.the diameter of which substantially corresponds to the diameter of the insulated wire to be contained therein.

The invention further consists in providing such strip with another wire containing member formed" of spring metal, U- shaped in cross section and having its opposite edges flaring outwardly and adapted when positioned between said cylindrical portions to be locked beneath said cylindrical portions thereby preventing the accidental displacement thereof.

The invention further consists in certain novel features of construction and arran ement of parts which will be understood y reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawin this form having been found to give satlsfactory and reliable ,results although it is to be understood that 1 the various instrumentalities of which the invention consists can be variously arranged Specification of Letters Patent.

and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a plan of one part of the container.-

Figure 2 represents a part of the container.

Figure 3 represents a plan of the complete container.-

Figure 4 represents a transverse section on line 4, 4, on Fig. 3, drawn to an enlar ed scale.

igure 5 represents an end view of the central art of the container, drawn to an enlarged scale.

Figure 6 represents a plan of the container showingthe central part being slipped into the body part, and

Figure 7 represents a side elevation of the container showing the central portion being snapped into position on the body art.

p Similar characters indicate like parts throughout the several figures of the drawplan of the other in s. I

in the drawings, 10 represents a back plate having a plurality of' counter-sunk perforations 11 therein to receive screws for securing the plate to the wall of a building.

The cylindrical portions 12 are separated sufiicientl to receive another wire-conta1ning memlier 14 in which is positioned an electric wire 15.

The opposite edges of the member 14 are flared outwardl as indicated at 16 in Figs. 4 and 5 of the rawings.

The member 14 is made of spring metal and when in position on the back plate 10 and between the cylindrical portlons 12 thereof, the flaring edges 16 will extend beneath the cylindrical portions 12 thereby preventin the accidental displacement of said mem er 14.

The interior diameter of the cylindrical portions 12 and the member 14 is substantially the diameter of the usual insulated electric wire used in the construction of buildings.

In some cases where only two wires are necessary for the installation, the detachable member 14 may :be omitted but it is preferable that this member 14 should be lnserted between the cylindrical portions 12 even it'it contained no wire.

It is obvious that a strip thus constructed is more or less ornamental in appearance which is of some advantage where the strips are necessarily exposed to view.

One of the great difficulties to be found in strips now in general use, is that they are provided with covers which do not always fit the body portion and require more or less hammering in order to properly position them upon said body portion.

This hammering is liable to break and injure the plaster or other surface to which the body portion of the strip is secured.

With the strip constructed in accordance with the present invention there is no necessity of hammering as the back plate is secured to the wall by means of screws and the device may be completed by sliding the intermediate member 14 into position as indicated in Fig. 6 or by snapping it into position as indicated in Fig. 7.

The flaring edges 16 yield sutliciently in the last case to permit them to pass the widest part of the cylindrical portions 12, subsequent to which they will spring outwardly and engage the under surface of the said cylindrical portions as indicated in Fig. 4 of the drawings.

When thus positioned the detachable strip may be quickly removed when desired but it cannot be accidently displaced.

In practice these strips are made several feet in length with their ends abutting other similar strips when installed.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, I claim- 13A containing strip for electric wires consisting of a back plate having parallel separated cylindrical wireenclosing por' tions having their walls extending to the face of said back plate and a detachable wire-enclosing member having resilient edges to engage said cylindrical wire-enclosing portions.

2. A containing strip for electric wires consisting of a back plate having parallel separated cylindrical portions adapted to receive electric wires and a detachable wire enclosing member adapted to be positioned between said cylindrical portions and having outwardly flaring edges adapted to extend beneath said cylindrical portions.

3. A containing strip for electric wires provided with two separated parallel wireenclosing portions and a detachable wireenclosing member between said separated wireenclosing portions and with its edges in frictional engagement with said wireenclosing portions.

4t. A containing strip for electric wires provided with two separated parallel wireenclosing portions and a detachable wireenclosing member of spring metal, the edges of said detachable wire-enclosing member being separated normally a greater distance than the width of the space between said separated parallel portions.
