Application filed August 28, 1908, Serial No. 450.635. Renewed September 8. 1910. Serial No. 5815334.
To all whom it may concern:
lie it known that we ll'lowi'an Guam Line, a citizen of the {initial States of Anierica, and .lnzics' A. FLEET! a subject of the l King" of (treat llritain. and both residents of i Portland. county of Cumberland, Shale ot? i Maine, have invented certain new and useful lniproveiuenis in lllectriwliainp Soc-lads, l of which the following is a specit' ration. l ()ur invention relates to incandescentelectric lamp sockets such as are now in common i use. these sockets comprising a cylindrical shell containing the lamp connections with a screw threaded recess on the lower end into which the lamp is screwed, and a hollow cap on the upper end tiltingthe cylindrical shell and detachably secured thereto and containing a hub with a screw threaded recess adapted to engage the end of the wall or other fixture. It has been found in practical use that th filaments of the new tungsten incandescent lamp are so frail and brittle that it is necessary-to support them in a vertical position. In the installation of the ordinary incandescent lainps many of the wall and chandelier fixtures are installed with the lamp sockets inclined at an angle usually about 455 degrees and in inst ailing tungsten lamps in such cases, it has been necessary to put. in new; fixtures or to insert a piece'of bent pipe to bring the socket into a vertical position.
The object of our invention is to provide means for changing the ordinary straight: socket into an angle socket which may he a p plied to straight sockets set at an angle so that the lamp will be brought to a vertical position and to do this without changing; in any way the parts of the original socket and the'invention consists of inserting liietwcen socket an angle piece which will bring; the lamp at any desired angle with the fixture.
lVe illustrate our invention by means of the accompanying drawing in which is shown a common form of lamp socket provided with our attachment.
In the drawing, Figure 1 is a. vertical section through the socket with our angle piece inserted and Fig. 2 a side elevation of the same.
l3 represents the socket proper consisting of an external cylindrical casing of thin metal inclosing the operating and coni'iecting parts of the lamp with a hollow sheet metal cap A having a flange 12 on its lower end adapted to fitnormally on the upper edge of the cylinder B. The cap A is also provided with. a hub o containing a screw threaded opening by which it is connected with the end of the fixture (1.. l? or the purpose of bringing the lamp to any desired angle with Tlidfikture we insert, between the 1 two parts oi' the socket an angle piece G here shown as a hollow shell of thin. metal having one end adapted to itv the llangcn of Q the cap and the other end provided with a flange 0 which is the duplicate of the flange a and is adapted to tit on the upper end of the cylinder B. The angle piece C has a.
lining c of fiber or other insulating mate The ends or the angle piece C are.
rial.
provided with the same coupling devices as are used on the ordinary lampsoehet to 86-- cure the two parts together here shown as a small projection on the upper end of cylin dcr B adapted to lit a corresponding recess in the cap and a like recess 0 in the lower flange 0 also adapted to receive the projection on the cylinder 13.
It will be seen that by the use of our attachment the ordinary socket can he quickly co vertcd into an angle socket or it may be used as a straight socket by removing the. attachment. in connecting up itis only use essary to lengthen the wires 11 (Z a llti'lO and connect them to the socket proper in the usual way.
While we have referred to our invention as applying to a lamp socket it, may be. equally well used in a-plug socke when it v is nepessary to bring the plug vertically from an angular fixture.
It is evident that the attachment may be made at any desired angle according to the position of thestirl ight. socket-and in prac-' the end of said shell and to be (letachnbly socket consisting or" the socket proper a hol- I secured thereto and :1 hollow elbow or angle low cap therefor adapted to be secured to the l piece the ends of which are adapted to fit enclnf the fixture and :1 hollow angle piece l the cup and the cylindrical shell respectively fida'pted to be insertecl between the socket l and to he (letaehably secured thereto. proper and the cap and to be detaehably se- I In Witness whereof, we have hereunto set cured to each part. ourhands this 17th clay of August. 1908.
