Oct. 17, 1950 P. F. EARLY MOUNTING FOR LAMPS Filed Dec. 15, 1945 INVENTOR P/IUL E EAPU ATTORNEY 'UUVNIHTED *sfrAT Patented Oct. 17, 1950 MOUNTING FOR LA PS v .-;1 aui Early, Dayton, Ohio, assigno r to Standard-Thomson Delaware This invention relates to a mounting for a lamp or the.like,-and the present application is a division of-my pending application, filed October 16, 1943, Serial No. 506,482, now Patent No.

-One object of the invention is to provide a mounting which enables the lamp to be quickly and easily adjusted about oneor more of'a plurality of axes.

A: further object of the 'invention'is' to provide such a mounting in which the pivotal connections are so controlled that thelamp will be firmly retained in the position to :which'it is moved but may be easily moved to other positions.

A further object of the invention is to provide such a mounting which is demountable without disturbing the pivotal connections, thus enabling the mounting and the lamp to be moved as a unit from one place to another.

v A further object of the invention is to provide such a mounting which is simple in construction,

easy to manipulate, and can be produced at a relatively' low cost.

Other objects 'of the invention may appear as the mounting is described in detail.

In the accompanying drawings Fig. '1 is a side elevation,partly in section, of 'a lamp equipped with the invention; Fig. 2 is an end elevation of such a lamp showing the socket member in section; Fig. 3 is a section taken on the line 3--3-of Fig. 2; Fig. 4 is a transverse section, partly broken away, taken on the line 44 of Fig. 3'; andFig .-5

isatransverse section taken on theline 5-5' of Fig. 3.

- In these drawings I have illustrated one embodiment of the invention and have shown the same as amounting for a light projecting device of the type known as a cockpit lamp" but it is'to be understood that the mounting may take various forms and may be used with lamps of other devices of various kinds.

The cockpit lamp here shown comprises a tubularbody l0 which-has within the same an electric lamp and a lens, which are not shown.

' f Application December 15,1945,SerialNo.635,374

" 18 Claims. (c1.24s 2 7s jacent the one end thereof, is a supporting ele the mounting. The supporting element may be construction the body is providedwith a device for connecting an electric cable therewith, including the tubular stud 38 rigidly secured to and projecting outwardly from said body,:and this stud is utilized as the supporting element for the ment by which the lamp may'be connectedwith I of any suitable character and may be secured to the body at any suitable point. In'the present Corporation, a corporation of lamp, a portion at least of the studbeing cylindrical=in form. The outer end v of the stud is screw threaded to receivea connector attached to the end ofacable 44. The-electrical connections are established in a manner set forth in the aforesaid application but form no part of the present invention, which is concerned only with the stud 38. The cylindrical portion of the stud has formed therein a circumferential groove vill; of substantial width to receive a part of the mounting, as will be hereinafter described.

In the particular embodiment here illustrated, the mount ng comprises a base 10 adapted to be mounted on a wall or other suitable supporting structure and having an outwardly extending socket portion H in which is mounted a stud 12, the socket and stud being preferably non-circular to prevent the rotation of the stud. Rotatably supported bythe stud is a device having parts forming a bearing-to-receive'and rotatably support the lamp supporting element '38. ,This device 'may be of; any suitable character and may besupported on the; stud 12 in various ways. In the present instanceime stud is provided nearits outer end-witha flange-13 and has at its outer'end a circularhead 14' which is spaced fromithe'iiangeby a='-groove 15. Mounted on,

this stud is a pairof substantially parallel members, or jaws; 16' each havingadjacent one end an internal arcuate recess 11 and havingadjace'nt; its other. end a substantially semi-circular surface'IS; The arcuate recesses 71 of the two jaws embrace the head 14 and support the jaws onthe stud, for :rotation about-the longitudinal axis ofthe latter. 'The surfaces .18 of' the jaws extend about" and-.-forma bearing for 'the supportingelementt38 on the body of the lamp, this bearing being transverse 'to the axis of the stud 12. with the other and retained-in engagement with the head of the stud l2 and with the-supporting element 38 in any suitable manner-but the connection ispreferably adjustable to control the frictional 'contactof the jaws with the head of the -,stud and with the supporting element. As

. here showm-the Jews. a n ed as r v8il'p -whichextends throug'ht one; jawand is v screw the friction between the jaws and theparts connected therewith 'maybe so regulated that The two jaws may be connected one the lamp may be easily adjusted about one or both axes to a selected position and will be retained in that position until positive force is supplied thereto.

The stud I2 is preferably removable from the socket to enable the stud, the jaws and the lamp to be removed from the supporting structure as a unit and yieldable means are provided for retaining the stud in the socket, so that it can be quickly and easily demounted. In the illustrated arrangement, the stud is provided with a recess, or groove, 19 to receive a spring pressed ball detent 80 mounted in an integral part 8| of the socket member H, the detent'thus normally retaining the stud in the socket but enabling the same to be Withdrawn so that the lamp may be moved from place to place within the range permitted by the conductor cable 44.

While I have shown and described one embodiment of m invention, I-wish it to be understood that }I do'not desire to be limited-to the details thereof as various 'modifi'cations may occur'to'a person-skilled in the art.
