Description
P. C. CALISS! ADJUSTABLE STANDARD Dec. 12, 1933.
Filed July 12. 1932 Inventor Po.u\ C- Colissi Patented Dec. 12; 1933 UNITED STATES This invention relates to adjustable lamp standards and more particularly to a universally, adjustable standard for what are known as sunray lamps.
As those familiar with the art to which thisv invention appertains well know, in order to prov vide for the most efiicient use of the so-called sun-ray? lamps, the latter must be arranged for adjustment into various positions to' most 10 satisfactorily suit the demands of the particular vuser of the lamp. Furthermore, the adjustment should be easily accomplished without necessitating the use of; numerous and complicated devices for effecting the necessary adjustment and for maintaining the lamp in an particular adjusted, position.- Heretofore and prior to this invention various attempts have been made from time, to time to secure a positionall'y adjustable sun; ray lamp,but the various expedients employed m to this end have not proved entirely satisfactory, have measurably increased the expense of ,the
unit, and have not been able to afforda maxi:
mum degree of positional adjustment.
It is among the principal objects of the present a invention to provide in astandard for av sunray lamp or the like a readily operable device or mechanism for effecting a substantially true pedestal 11 is a yoke or bracket 14 having sub-- universal adjustment of the lamp.
,Afurther and more specific object of the in-.
a yention is the provision of a standard .having' handle-operated means for shifting the lamp in any desired'direction, the said means being so,
arranged and so designed as to securelyflmaintain a lamp in any given or" required adjusted posigg tion. 1 'l 7 'Still further objectsof the invention are the provision of a compact, simple and inexpensive ball and socket joint between the vertically, extending pedestal andthe laterally extending arm n ofthe "fsun-ray lamp whereby .the latter may be not only rotatedabout an axis extending diametrically through the ball of the'jointbut alsoshifted angularly with respect to the horizontal y axis of the socket for said ball, the .ball and f socket Joint having operatively associated therewith readily adjustable spring-pressed means for eilecting the maintenance'of said laterally 'ex' tending armin any desired adjusted position.
Other objects of the inventionrelating to details 5 01' construction and advantages resulting therefrom will be apparent more fully hereinafter;
The invention consists csubs tantially in the arrangement and.
relative location of parts,-all as described more fully hereinafter, as shown in'the accompanying v combination, construction,
ray? lamp constructed in accordance with and 69 embodying the features of the. present invention;
Figure 2 is a perspective view of the lamp showing the same in an adjusted position other than that shown in Figure 1; Figure 3 is a view showing the lamp in a still further adjusted position v ,Figure 4: is an enlarged elevational view, partly in vertical section, of the universal jointconstruction; and Figure 5 is an enlarged sectional detail of a portion of the structure shown in Figure l.
Referring now more particularly to the drawing, it will be observed that'the'standard for'the stantially parallel, vertically extending side bars 15-16; the upper ends of'which' are preferably joined together bythe transversely extending bar 17 to afford requisite rigidity and strength to the yoke 14. j Across bolt 18 may also be provided for interconnecting the lower-portions of the side; bars 15 1s.; p g r 5 j; r
Fixedly secured'to the-iriner surface of one or the sidebars, in the present instance, the side bar 16, is a member-19 having aspherical seatjor depression 20 in the inner surface thereof. The outersurface of thismember i9 is disposed fiatwise against the inner surface of the bar 16 and isperrnanently and fixedly secured theretoby the screws 21 or othersecuring elements. I Adjustably secured to thB DPDOSite side bar 15 in axial alinement with the member 19 is a secondfmernber 22, thelatterljinember being also" providedwith a sphericalseat' or depression 23 in the inner surface thereof. This member22 is axially movable toward and away from the inner surface of the side bar 151 to thereby vary'the eif'ective distance between the alined spherical seats of the memberslll and 22 f ora/purpose which will be apparent immediately hereinafter.,,
As appears most clearly in Figures 4 and 5 the side bar 1'5, upon which the member 22, is adjustet members being provided with spherical seats, said socket members being axially movable relatively to each other, a spherical member accommodated between the spherical seats 01' said socket members, an elongated handle secured to and carried by said spherical, member extending in a direction substantially opposite to that of said handle, and a lamp carried by the extremity of said arm, said lamp having a ball and socket connection with the supporting arm therefor,
and spring-pressed means tending constantly to urge said socket members into frictional contact with said spherical member.
