FIXTUBE SUPPORT AND BRACKET.

Specificaton of Letters Patent.

Patentea aui at, asia.

Application filed March 5, 1915. Serial Ne. 12,448.

To all 'w kom it may concem:

Be it known that I, WILSON R. BLAIN, a

citizen of the United States, residing at Albany, in the county of Linn and State of Oregon, have invente'd new and useful Improvements in Fixture Supports and Brackets, of which the following is a specication.`

This invention relates to a bracket for supporting electric lamps or other electrcal fixtures, and one of its objects is to provide a bracket of* simple and inexpensive construction whereby the lamp or other fixture may be supported, raised and lowered as required, and also adjusted to different posltons in a room or apartment.

A further, object of the invention is to provide a bracket embodying means for 'guiding and holding the electrc conductng cord or wire, so that the same may' be adjusted to raise and lower the fixture as required' and .maintain the same in adjusted position.

The invention consists of the features of const'ru'ction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in whch F igure 1 is a View showing the device as used as a. lamp fixture and applied to a ceiling to adjustably support the lamp withina roomor apartment. Fig. 2 is a detal section on the line 2- -2 of Fig. 1. Fig. 3 is a fragmentary plan view of the suspending arm showing the spring guiding and clamping jaws thereon.

In carrying my invention into practice, I provide a wall or ceiling platel, which may be suitablysecured in position upon the wall or ceiling, and which is provided with a projecting tubular stern 2 for the passage of the electric conducting cord or wire 3, leading through the wall or ceiling from a suitable source of current supply. A hanger arm 4 is pivotally mounted at one end, as indicated at 5, upon the stern 2, to swing in a horizontal plane, and said arm is preferably outwardly and downwardly curved from its pivotal support on a desired arc, the degree of curvature of the arm 4, which may vary under difl'erent conditions, serving to regulate or control the elevation of the bracket within the room `or apartment in which it is located.

Hinged at one end to the free end of the hanger arm 4, as indicated at 6, is a connecting arm 7,'which inclines outwardly and downwardly from said hanger arm and has its opposite end 8 bent on a downward curve and arranged to support a suspending arm '9 pivotally mounted at one end, as at 10,

upon the end 8 of the arm 7 to swin ina horizontal plane, the arm 9 being o r relatively greater length than the arm 7, so that when the respective arms are arranged in alinement the free end of thearm 9 will eX- tend outwardly beyond the free end of the arm 4, thus permitting of certain adjustments of the arms with relation to and without interference from each other.

It will be evident from the foregoing description that the arms 4, 7 and 9 are adjustable to different relative angles and to different positions to lengthen or Shorten the bracket as a whole, thus allowing the free end of the suspending arm 9 to be disposed to support the lamp or other fixture at any point within the room or apartment in which the device is arranged for use.

The arms 4, 7 and 9 are provided with guiding and clamping members 11, arranged at inter-Vals along the same, and each consisting of a pair of spring jaws 12 having their free ends arranged to form the guide space 13 and their inner portions arranged to form approximating or abutting clamping surfaces 14. These guiding and clamping devices are adapted for coperation with the cord or conducting wire 3, which is threaded therethrough along the respective bracket arms, a portion of the cord or wire being, however, arranged in the form of a slack bight or loop 15. The guiding and 'clamping members of the arm 1- project downwardly, while the guiding and clamping members of the arms 7 and 9 project upwardly, -as shown; The free end of the cord supports the lamp or other fixture 16 and clepends at the end of the arm 9 between a pair of guiding and clamping jaws 17 which' have beveled ends to form a fiaring space or entrance 18 and clamping surfaces 19 between which clamping surfaces the cord normally extends. In practice, the cord may be gripped between the faces 7 of the jaws 7 to support the fiXture 16 at the 'desired elevation, and at all times the cord is arranged to'extend between said faces so that said jaws 17 will establish a proper resistance to the movement of the cord. The cord also extends either loosely through the spaces between the jaws 12 of the guding and clamping members 11 or may be drawn down between the clamping surfaces 14: of said jaws, thus enabling the cord to be ad usted with ease and convenience and grippecl or held upon the braoket arms with greater or less force, according to the weight of the object which is to be Suspended, so that the depending end of the cord will support the fixture or object at any desired elevation. The slack portion 15 of the cord permits adjustment of the fixture as to elevation to a comparatively wide degree, and this extent of adjustment may be exceeded by dsconnecting the cord from the guiding and clamping members of either or both of the arms 4 and 7 as will be readily understood. It will be evident, however, that these guiding and clamping members, in which the cord may be gripped as tightly as desired, will normally hold the cord while permittng it to be run out or extended when pulled with the desired force, so that the fixture may be raised and lowered with ease and convenience. The jointed arms of the bracket furthermore permit the fixture to be adjustedto any point horizontally in a room or apartment or closet passageway communicating with said apartment, the advantages of which will be evident.

I claim 2- 1. A fixture suspending device comprising a wall or ceiling bracket, a longitudinally curved hanger arm pivotally mountediupon said bracket to swing in a horizontal plane, an inclined connecting arm pivoted at one end to the lower end of the hanger arm and having its opposite end downwardly curved, a suspending arm pivotally mounted upon the downwardly curved end of the connecting arm, guiding and gripping members upon said arms, and a conducting and fixture supporting cord threaded through and adjustable in said guiding and gripping men-- bers.

2. A fixture suspending device comprising a Wall or ceiling bracket, a longitudinally curved hanger-arm pivotally mounted upon said bracket to Swing in a horizontal plane, an inclined connecting arm pivoted at one end to the lower end of the hanger arm and having its opposit-e end downwardly curved, a suspending arm pvotally mounted upon the downwardly curved end of the con nectng arm, guicling and gripping members upon the respective arms, each consst'ng of a pair of spring jaws formng a guiding portion and clamping surfaces, a pair of guiding and gripping jaws upon the free end of the suspendng arm, and a conducting corcl extending through the bracket and also through said guding and conducting nembers along said arms and depending from the free end of the suspending arm, said cord having a slack portion at the anglc of interseetion of the hanger and connectng arms.

In testimony whereof I afiix my signature in presence of two witnesses.
