REFLECTOR.

Specification of Lettersfatent. Patented J 116 20, 1911. Application filed June 14, 1910. SerialNo. 56 6,761.

"To all whom it may concern:

Be it known that I, ELMER W. UTZLER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in-Re flectors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to the class of reflectors and has for its object to provide an adjustable reflector and a combined independentlyadjustable lamp, whereby the reflector and lamp may be adjusted together orv independently of each other, together with other features of construction and operation as shall be more fully hereinafter described.

The invention is designed to rovide means for illuminating any particu ar area or space, as portions of a show window and to focus the light to the best advantage and with a view of securing economical and effective results to the highest degree.

In the drawings illustrating the inven= tion:Figure 1 is a vertical sectional-view of a reflector and its supporting frame and lamp. Fig. 2 is a view in side elevation of Fig. 1, the reflector being shown in transverse-section. Fig. 3 is a view inelevation of a plurality of reflectors mounted for operation together. Fig. 4 is a view at right and having its interior covered with a suitangles to Fig.3. Fig. 5 is a plan view of the reflector shown in Fig. 1, t e lamp su porting mechanism being in section on t e line V. V. of Fig. 1. Fig-6 is a detail view showing a flexible adjustable lamp bracket.

2 is the reflector shell or shade, which may be of any suitable-or desired shape or construction but which is preferably of a single piece of glass-or other suitable material, properly curved and arranged as to its side walls torrefl'ect the light therefrom,

. pending arms 7 and reflector in different positions with relation to the supporting arms 6, as indicated in dotted lines in Fig. 2.

Arms 7 are vertically slotted as at 9, and

between the arms extendingacross from one to the otheris: a lamp supporting bracket 10 having terminals 11 which bear against the inner side of arms 7 and are secured thereto at varying heights or at angular positions forwardly or backwardly, whereby to position the lamp 4, by means of thumb screws 12, 12.- "Said screws extend inwardly through slots 9 and into the terminals 11, and by loosening them the bracket 10, which embraces the lamp socket as shown, may be set and secured in any desired position either vertically or angularly. The bracket 10 may conveniently be made of semi-circular clamping portions, secured together by one or more screws as indicated whereby to fixedly hold the lamp socket between them. Ordinarily however, it is desirable that the lamp 4 shall be free to swing from its supporting bracket, so as to hang verti-' cally independently of whatever position the bracket may assume. For such purpose, the bracket 10 is provided with pivotally connected securing terminals 10 having securing screws 12' and jointed as at 10", as clearly shown in Fig. 6. By this arrangement, the lamp is free to assume a vertical position at all times, irrespective of whatever positions thereflector or 1ts supporting frame may assume, and thus the best efii ciency of the lamp as to focuslng and time of service is assured.

The lower terminals of arms 7 are bent in opposite directions as indicated at- 13, engaging underneath-the inner edges of the reflector around the opening 5, companion clamps 14 engaging the upturned reflector edges and securing it in the desired position by thumb screws 14, whereby to fixedly hold the reflector forwardly or backwardly with relation to the normal position of the lamp.

By reason of the elongated opening 5, the clamping terminals of the arms 7 V may be adjusted forwardly or backwardly of the reflector thereby adjusting the lamp bracket and lamp likewise. By this means the lamp and reflectorare accurately adjusted wit relation to each other and set to the desired focus, and this adjustment may be secured quite independent of the other adjustments referred to. This adjustment of the lamps with relation to thereflector is of especial advantage in' adjusting lamps of varying efficiency or candle power to the reflector,

whereby to secure the best results in focusing the reflected light. By this construction, it will. be seen that the reflector may be tilted forwardly or backwardly on its pivotal joints 8 and secured thereby in any desired position; also that the lamp 4 may be set forwardly or backwardly, and raised or lowered or likewise tilted forwardly or backwardly with relation to the reflector.

"By such adjustment of the reflector and lamp, the reflected light may be focused to the best advantage and within a very extensive range, due to the ample range of adjustment of the parts.

When it is desired to employ a number of reflectors and to adjust them all together for uniformity of distribution of the combined lights over an extended area, the arrangement shown in Figs. 3 and 4 may be utilized. In such construction, each pair of arms 7 is pivotally connected with the. terminals of a Y-shaped arm 15 at 16 and the other end of said arm is connected at 17 with the end of a lever 18, one for each reflector. Each of said levers 18 is secured to a common rock shaft 19 mounted at 20, 20, in suitable bearings and having at one or both ends an operating lever 21' and a handle extension 22 of any desired construction. By this or other equivalent means it willbe seen that all of the reflectors and their lamps may be uniformly adjusted forwardly or backwardly on their pivotal joints 8 by manipulation of the lever"mechanism, without in i any way impairing the efliciency of each retail by the skilled mechanic but all such changes are to be considered as within the scope of the following claims.

.-What I claim is 1. The combination of a double-sided supporting frame, a reflector carried thereby, and a separately adjustable lamp bracket carried by said frame adapted to adjust-the lamp vertically and laterally. if?

2. The combination of a supporting frame consisting of pivotally jointed sections, means for securing the reflector thereby'at varying positions, and a separately ad ustable lamp bracket'carried by said jointed sections.

3. The combination with a reflector having' an opening therethrough, of a doublesided support engaging the reflector at each side of the opening, and a freely pendent lamp carried by said support and extending through the opening into the interior of the reflector. v

4. The combination. with a reflector having an opening" therethrough, of a d0ublesided support engaging the reflector at each side of the opening, and a lam bracket carried by .said support and a justable with relation thereto.

5. The combination with a depending bracket, of a reflector, mechanism connecting the bracket and reflector'adapted to be adjustably set and secured with relation to 7 said bracket, and a separately adjustable lamp bracket.

6. The combination with a depending I bracket, ofa reflector, connecting mechanism adapted to be adjustably set and secure"d with relation to said bracket,'and a separately adjustablelamp bracket having a freely swinging lamp attachment.

7. The combination with fixed supports, of supplemental arms pivoted thereto, means for securing said arms in varying positions, and a reflector secured to the terminals of said arms, having a clearance opening for the lamp.

.8. The combination with fixed supports, of supplemental arms pivoted thereto, means for securing said arms in varying positions, a reflector secured to the terminals of said arms, and a pivoted lamp bracket adjustably secured in said arms.

9. The combination with fixed supports, of adjustable arms and means for fixedly securing said arms with relation to said supports, an apertured reflector secured to the'terminals of said arms, an adjustable lamp bracket having a slotted engagement with said arms, and a lamp secured therein and extending into the-interior of the reflector, substantially as set forth.

10. The combination with fixed supports, of adjustable arms and means for fixedly securing said arms with relation to said supports, an apertured reflector secured to the terminals of said arms, an adjustable lamp pivotally supporting bracket having a slotted engagement with said arms, therein and extending into the interior of the reflector, substanti-allyas set forth.

11. The combination with a plurality of pendentlysupported reflectors and means said. reflectors, of

1 means provided with an operating handle and connections to each 10' of the reflector supporting means for adjusting all of the reflectors together, substantially as set forth.

12. The combination with a plurality of pendently supported reflectors and means and a lamp pivotally secured to adjust all of the reflectors together, sub-,

stantially as set forth.

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