DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, the numeral 10 designates a roof eave trough of conventional type usually embodied in residential house construction, which trough includes an upstanding edge flange 11, horizontal web 12 and the depending flange 13 which terminates in the flange edge 14. The flexible clamp hanger constituting this invention is generally designated by the numeral 15 and is shown in interlocked relationship with the aforesaid eave trough flange. A plurality of such hangers may be applied to an eave trough flange in relative spaced relation to support a string of ornamental electric lights generally exemplified by the outdoor type plastic electric lamp socket 16, lamp 17 and circuit cable 18. Wherever the context so permits, the term "eave trough flange" may be deemed to include the aforesaid flange areas, parts or components specifically designated by the reference numerals 11 to 14 inclusive.
The hanger generally designated by the numeral 15 may be in the form of a light gauge sheet spring steel stamping, comprising a hook shank 19, a web 20 perpendicular to the said shank 19, a leg 21 depending from the said web 20, and a toe 22 underlying the said web 20 and extending towards the said shank 19, all in the unitary formation of a hook which is adapted to overlie and contact the aforesaid eave trough flange.
Two clamp arms, each generally designated by the numeral 23, extend in right-angular relationship to and from the hook shank 19, and combinatively therewith form a flexible U-shaped clamp. To attain maximum flexibility and clamping value, the arms 23 shall preferably be in the curvilinear shape shown in FIG. 3, with the lower edges 24 flared slightly outwardly in relation to the top edges 25 thereof, so as to generally conform with a frustrum-shaped electric lamp socket. The end 26 of each arm is flared outwardly, as is shown in FIG. 3, to facilitate insertion of an electric lamp socket between the said arms. The arms 23 are in part flexibly expandable or outwardly extendable to accommodate a wide range of socket sizes, such as from the shape shown in FIG. 3 to the shape shown in FIG. 2, which latter view shows the said arms in electric lamp socket clamping, gripping and holding position. A boss or protuberance 27 extends from the hook shank 19 between the arms 23 and serves to limit movement of the electric lamp socket 16 towards the hook shank 19, if the said socket is gripped between the confronting curved areas of the said arms.
Decorative or ornamental electric lamp sockets and cable assemblies are commonly manufactured and sold in units embodying about eight or 10 lamp outlets, and it is the general purpose of this invention to provide a very simple hanger which may be snapped on to each socket and in turn hooked over the upstanding edge flange of an eave trough, after which the sockets and lamps may be shifted along the eave trough flange into appropriate spaced relationship. As is shown in FIG. 1, the hanger shank 19 may extend parallel to the eave trough upstanding flange 11; the web 20 of the hanger overlies the web 12 of the eave trough; the leg 21 of the hanger extends downwardly and inwardly of the eave trough depending flange 13; and the toe 22 of the hanger underlies the edge 14 of the eave trough flange 13. The proportion and formation of the aforesaid parts of the shank hook should be such that the hanger may interlock with the eave trough flange by first holding same by hand with the shank 19 overlying the web 12 at an angle of about 45°, and then by shifting the hanger outwardly so that the toe 22 thereof moves under the edge 14 of the flange 13, following which the hanger may then be tilted downwardly to the position shown in FIG. 1. The space between the end of the toe 22 and the confronting shank 19 should be slightly greater than the vertical height between the edge 14 of the flange 13 to the top of the web 12.
The interlocking engagement of the hanger 15 with the eave trough flange is such that the hangers 15 may be applied to or removed from the eave trough, with or without the lamp socket 16. After application of a plurality of hangers 15 to which electric lamp sockets and cable assemblies have been applied, the lamps and the sockets may be freely adjusted endwise of the eave trough 10 to achieve desirable spacings, but when adjusted will remain in such position and the circuit cable 18 extending from socket to socket will have limited downward deflection, for the reason that the weight of the said cable causes a socket to tilt slightly laterally and the extent of tilting is restricted by the toe 22 which is, accordingly, canted until one end or corner of same contacts the edge 14 of the eave trough. The lamp socket 16 should be inserted between the arms 23 of the hanger, as is shown in FIG. 1, with the circuit cable 18 overlying the top edges 25 of the arms 23. By this arrangement, the cable 18, bearing against the tops of the said arms, prevents the sockets from slipping downwardly between the said arms.
It has been determined experimentally and under use application that the curvilinear formation of the arms 23 will accommodate a wide range of socket sizes and shapes usually found in ornamental lamp sockets of the type specified, and that sockets may be inserted between or removed from the arms 23 with facility. It is desirable that the arms 23 be so shaped that a socket 16 is held substantially perpendicular to the arms, as is shown in FIG. 1.
This invention relates generally to electric lamp socket hangers, and specifically to a device adapted to detachably interlock with and hang from the upstanding edge flange of a roof eave trough of the type commonly used on houses, and to which an ornamental electric lamp socket may be attached or detached with facility.

The hanger generally designated by the numeral 15 may be in the form of a light gauge sheet spring steel stamping, comprising a hook shank 19, a web 20 perpendicular to the said shank 19, a leg 21 depending from the said web 20, and a toe 22 underlying the said web 20 and extending towards the said shank 19, all in the unitary formation of a hook which is adapted to overlie and contact the aforesaid eave trough flange.
Two clamp arms, each generally designated by the numeral 23, extend in right-angular relationship to and from the hook shank 19, and combinatively therewith form a flexible U-shaped clamp. To attain maximum flexibility and clamping value, the arms 23 shall preferably be in the curvilinear shape shown in FIG. 3, with the lower edges 24 flared slightly outwardly in relation to the top edges 25 thereof, so as to generally conform with a frustrum-shaped electric lamp socket. The end 26 of each arm is flared outwardly, as is shown in FIG. 3, to facilitate insertion of an electric lamp socket between the said arms. The arms 23 are in part flexibly expandable or outwardly extendable to accommodate a wide range of socket sizes, such as from the shape shown in FIG. 3 to the shape shown in FIG. 2, which latter view shows the said arms in electric lamp socket clamping, gripping and holding position. A boss or protuberance 27 extends from the hook shank 19 between the arms 23 and serves to limit movement of the electric lamp socket 16 towards the hook shank 19, if the said socket is gripped between the confronting curved areas of the said arms.
Decorative or ornamental electric lamp sockets and cable assemblies are commonly manufactured and sold in units embodying about eight or 10 lamp outlets, and it is the general purpose of this invention to provide a very simple hanger which may be snapped on to each socket and in turn hooked over the upstanding edge flange of an eave trough, after which the sockets and lamps may be shifted along the eave trough flange into appropriate spaced relationship. As is shown in FIG. 1, the hanger shank 19 may extend parallel to the eave trough upstanding flange 11; the web 20 of the hanger overlies the web 12 of the eave trough; the leg 21 of the hanger extends downwardly and inwardly of the eave trough depending flange 13; and the toe 22 of the hanger underlies the edge 14 of the eave trough flange 13. The proportion and formation of the aforesaid parts of the shank hook should be such that the hanger may interlock with the eave trough flange by first holding same by hand with the shank 19 overlying the web 12 at an angle of about 45°, and then by shifting the hanger outwardly so that the toe 22 thereof moves under the edge 14 of the flange 13, following which the hanger may then be tilted downwardly to the position shown in FIG. 1. The space between the end of the toe 22 and the confronting shank 19 should be slightly greater than the vertical height between the edge 14 of the flange 13 to the top of the web 12.
The interlocking engagement of the hanger 15 with the eave trough flange is such that the hangers 15 may be applied to or removed from the eave trough, with or without the lamp socket 16. After application of a plurality of hangers 15 to which electric lamp sockets and cable assemblies have been applied, the lamps and the sockets may be freely adjusted endwise of the eave trough 10 to achieve desirable spacings, but when adjusted will remain in such position and the circuit cable 18 extending from socket to socket will have limited downward deflection, for the reason that the weight of the said cable causes a socket to tilt slightly laterally and the extent of tilting is restricted by the toe 22 which is, accordingly, canted until one end or corner of same contacts the edge 14 of the eave trough. The lamp socket 16 should be inserted between the arms 23 of the hanger, as is shown in FIG. 1, with the circuit cable 18 overlying the top edges 25 of the arms 23. By this arrangement, the cable 18, bearing against the tops of the said arms, prevents the sockets from slipping downwardly between the said arms.
It has been determined experimentally and under use application that the curvilinear formation of the arms 23 will accommodate a wide range of socket sizes and shapes usually found in ornamental lamp sockets of the type specified, and that sockets may be inserted between or removed from the arms 23 with facility.
