H. J. NEWMAN.

ELECTRIC LIGHT BRACKET.

APPLICATION FILED NOV. 12. I915.

1 1 86,428. Patented June 6, 1916.

HAROLD J'OHliT NEWMAN, OF CAVOUR, SOUTH DAKOTA.

ELECTRIC-LIGHT BRACKET.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed November 12, 1915. Serial No. 61,116.

To all whom it may concern:

Be it known that. I, HAROLD J. NEWMAN, a citizen of the United States, residing at Cavour, in the county of Beadle and State of South- Dakota, have invented new and useful Improvements in Electric-Light Brackets, of which the following is a specification.

This invention relates to an adjustable lamp bracket and more particularly to a ball and socket bracket.in which means is provided for increasing the frictional contact between the ball members and the socket members for taking up wear and insuring a tight fit between the members for obvious reasons.

The primary object of the invention is to construct a lamp bracket of members through the medium of which the lamp may assume a variety of positions irrespective of the connections between the lamp and the stationary support.

Another object of the invention is to provide simple means for increasing the frictional contact between the ball members and the socket members. A further object of the invention is to so form the members in duplicate shape that said members can be readily renewed and any slight wear of the contacting surfaces between the socket member and the ball member can be readily taken up by the tightening means hereinafter described.

Other objects of the invention will appear hereinafter, the novel combination of the elements being pointed out in the appended claim.

Referring to the drawings :Figure 1 is a side elevation of my device showing the same connecting a lamp socket and lamp. Fig. 2 is a longitudinal section showing the cooperation between one ball member and its associated socket member. Fig. 3 is a top plan view of a portion of my invention.

Fig. 4; is a section on line i4: of Fig. 1.

Referring to the drawing, the numeral 1 designates any ordinary lamp socket in which is readily mounted the usual electric. bulb 2 that receives its current in the usual manner through a cord conductor 3 from an electric lamp plug 4. My invention is interposed between the usual lamp plug 4' and the lamp socket 1. In this particular instance the first ball member of a plurality of ball members 5 is rigidly connected to the lamp plug 4 by means of the shank 6. Inclosing the major portion of each ball member, is a socket member 7 each of which has a rigid connection with the adjacent ball member by means of a shank 7 similar to the heretofore mentioned shank 6, with the exception of the lamp socket member which angles as shown at 11. Attention is called a to the fact .that previous to bending up the ends of the alternate fingers they have the same length as those fingers that have not their extremities bent up with the result that the band 12 which encircles the fingers is spaced a slight distance from the free ends of the fingers that are not bent. This band 12 which encircles all of the fingers is prevented from moving in one direction by means of a bulged portion of the socket member While its movement in the opposite direction is prevented by the angular bent extremities of the fingers, thus it will be seen that when the screw 13 is tightened by pressure being applied thereto, the ends of the band will be drawn together so as to contract the interior area of the socket member which causes the increased friction between the outer surface of the ball member and the interior surface of the socket member for insuring the bulb 2 being retained in any of its adjusted positions.

Obviously various changes could be made in certain parts of the device by one skilled in the art without departing from the spirit and scope of the invention, and for this reason I desire not to be limited to the precise arrangement and constructions of the parts as disclosed.

What I claim and desire to have protected by Letters-Patent of the United States is A lamp bracket comprising a plurality of ball members and a plurality of socket members inclosing said ball members, each of said socket members being slotted at spaced intervals to form fingers the alternate ones of which havin right angularly bent extremities and a and encircling the fingers of each socket member to one side of the center of the latter and abutting the right angularly' bent finger extremities.

In testimony whereof I aflix my signature in presence of two witnesses. HAROLD JOHN NEWMAN. Witnesses:
