s'PEcFcATIoN forming part of Letters-ratent'rro. 702,649, dated :rune 17, 1902. .ippumiontled April 22,1901.;y senti No. 56,848. (No model.)

To @ZZ whom it may 0oneenn- Be it known that LWILLIAM IL iRvErnaJ citizen of the United States, residin gin New York city, in the county of Kings and State of Newy York, have invented certain new and useful Improvements in Illuminators, of which the' following is a specification.

This invention relates to illuminators, and'- particularly to an improved reflecting device for throwing" light upon objects,fand is particularly adapted for the purpose of throwing different-colored lights upon'a stage, whereby the whole stage or certainl parts thereofor performers thereon are made to stand out in a bright light or in any colored light desired, and is especially useful to add to the attraetions of various spectacles.

This invention has for its object to prov-ide a light with a reiiector which may be readily adjusted in focus in position, so that it may be in a horizontal plane with thecarbons offan arc-light when the latter are shortened by consumption, and also to provide convenient means for manipulating the selective transmitting media, such as different-colored glass slides, by which the colorof the light thrown upon the object desired to be illumined may'` be varied as required; and a further object' of this invention is to reflect the light to different positions by the upward or downward adjustment of the reflector.

The invention comprises in general suitable supporting means, sueh as a cabinet, provided in front at the top and bottom with ways in which -they selective transmitting media may be moved and at its back'with-an adjustable slide to which areflector is attached andon one side with a suitable'opening for the insertion ofthe-handvand arm of the operator. Within the cabinet is a bracket which supports a pivoted member carrying a light, which by means of said memberis adj ustable to any point within a given radius of the reflector and said member, so that by a vertical adjustment of the reflector and the radial and transverse adjustment of the member and light a wide and universal range of light reflection is obtained.

In the drawings accompanying and forming part of this specification, Figure l is a perspective view of the improved device. Fig. 2 is a detail section showing the reiiectorlslide mounted in guid'eways at the back ofy thecabinet. v y

The device generally is represented by A, j and comprises supporting means, shown as a cabinet-having a bottorn`3` and top 4 and three closed sides `5; The front is open, and thecabinet 2 is provided atitop and bottom in front with ways 6,'extending across said front', in which different-colored glass slides (not shown) may be slid. At the rear of the cabinet,opposite the open front,is a verticallyadjustable slide 7, movable in guideways 30 by a thumb-piece 31,-' and to such slide 7 areiiector 8 is secured. On one side of the cabinet an opening 9 may be provided, through which opening 9 the operator may insert his hand and arm, such opening 91being northe rear to the front opposite thereiiector 8' is abracket 11. A standard-12 is'adjustably mounted on said bracket and is here shown as'having a head'13,with an aperture'14 therethrough, adapted to slide on vthe bracket 11 and provided with a thumb-screw 15,by which it, may be retained in different positions. A frame 16, shown as comprising a vertical section`17, from which three arms 18 extend at right angles, is revolubly mounted on the standard 12. At a suitable distance from the vertical portion of the frame 16 a guide-rod 19 extends through and is secured to the arms 18. Inthe outer ends of the arms 18 a rod 20 may be rotatably mounted and provided at its lower end with Y suitable means for turning such rod 20,'shown as athurnb-pi'ece 21. The Vportions of the rod 20 on either side of the middle arm 18 are provided with means of vertically-adjusting the carrier 22, hereinafter described, such means beingshown here asright and. left screw-threads.- Slidably mounted on the guide-rod 19, one on each sideof the middle arm 18, are carriers 22, each shown as having a screw-threaded aperture 23 complementary to the screw-threads on the corresponding portion of the rod 20. Links 23 may be secured tothe reduced outer IOO ends of the blocks 22 in such a manner that they may be secured at dierent angles horizontally to said blocks 22, the outer ends of the links 23 being shown as having a slot 24.'

Carbon-holders 25 of any desired form may be secured to said links 23 by any suitable means, such as a screw 24:' passing through the slots 24, said carbon-holders 25 being provided with suitable means of securing carbons 2G therein, such as the thumb-screws 29. The links 23 may be provided with posts 2S to receive the electric wires. (Not shown.)

The device may be modified in details of construction without departing from the principles or sacrificing the spirit of the invention, and I do not limit myself to the particular form shown and described.

The operation of the invention is as follows: The operator having by means of the slide 7 adjusted the reflector S to suit the height of the light and by means of the rod 2O adjusted the carbons 2G with reference to each other turns on the electricity and by means of sliding the standard 12 along the bracket l1 arranges the focus, while by turning the frame 16 and adjusting the reflector 8 he can direct the light in any direction he wishes either in the focus of the reflector or toward the part of the cabinet having no reflector and by means of the thumb-piece 2l keep the carbons 2G in proper relation with each other and take up any wear that occurs. At the same time by moving the colored-glass slides in the ways G so as to be in front of the reflected light he can change the color upon the object as desired, and by moving the light away from the reflector a diffused light may be thrown upon any portion of or the whole of the stage.

While the reflector' may be brought to a level with the light, it can also be moved to throw the reflection upward or downward, as desired-that is to say, by adjusting the reflector above the level of the light it will throw an upward reflection and by adjusting it below said light the reflection will be cast downward.

It will be seen that the source of light of this illuminator is adjustable toward and from a reflector and also to any point within a given radius of said reflector. It will be further noted that the reector is also vertically adjustable with respect to the source of light and that by the Vertical adjustment of the reflector and the radial adjustment of the light and the longitudinal adjustment of the light-carrying member it becomes possible to generate a varied and universal reflection.

Having described my invention, I claiml. In an illuminator, the combination with a cabinet adapted to carry colored slides, of a vertically-adjustable reflector located in said cabinet; and a revoluble member also mounted in said cabinet for adjustment with reference to said reflector and carrying a source of light, said source of light being adjustable upon said frame and with respect to the reflector.
