Application flledrliiarch 7, 1908. Serial No. 419,646.

To all whom it may concern:

Be it known that l, (inocon ll. Ricks, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful .lniproveinonts in Lump Refrcctors and Shades, of which the following It specification.

My invention has for its object the provision of o lzuup shade and rel'rnctor which shall be adjustable so that the rays of light can be concentrated and thrown with increased power to any certain point; so that by this adjustment any point can he reached by iul iustii "he rel'rsctor ports to throw the light in various directions.

The attachment only be applied to coal oil, gas or electric lumps or lights.

By my invention i rainy use the lamp shade in the ordine way. or use it as an ornament or illuminated slmde, or as o refroctor for concentrating tho light, the parts all being intcrolmngecble. l employ n hulls eye lens to throw the light to the desired point and the bull's eye lens can he moved to assume varying inclined positions and also can he odjusted lunizcontnlly mid vertically.

'lhc shade consists of a l'ruinework, so made that slides can he slid in and out thereof, the slides consisting of plates of tin or metal or glass, plain or ornamental, one side being formed to hold it bull's eye lens, which is held in on auxiliary plate which can be adjustod vertically or laterally. By means of this vertical and lateral adj ustnicnt the hulls eye lens can adjusted so that the rays of light will be thrown ntvorying singles to reach ositions or objects. Thus in reading by :1

cm the hulls eye can. be adjusted to the .remliers wants or for instance if it were used to throw the light on door or window it could be adjusted for such purpose. This adjustment is further more accurately attained as the side oi the shade in which the b'ulls eye .is located is hinged and can be let up and down. 'ihc device can be used on a lamp as an orniuncnt, as a shade, it rcl'ructor, for throwing the light, for reading pur )oses, for a. dark lantern, for chandeliers, lored room and hell light to throw the rays to one pair ticulcr point and analogous purposes, on account of the interchangeable nnd'ndjustable nuturc o f its parts in the accompany 1g o part of this specification:

drcwing forming Figure 1 is on 130-.

metric view of c him with my invention at-- tcchcd thereto, the liody of the lamp being broken away. Fig. 2 is c'perspective view of the lower part of the shade showing thev rel'rcctorproper. Fig. 3 is an end or side view of the refrcctor broken sway at one side to show construction. Fi .4 ,-.is a sectional view taken at line 4-4 of ig. 3. i Fig. 5 is. sectional view taken at line 5- -5 of F ig. 2. Fig. 6 is a view in elevation of the bull's eye lens shifter. Fig. 7 is a view in elevation of one of the panes of glass used in the device to fill the side framework.

The device or attachment is in the form of a truncated yramid, having four sides, 1, 2, 3 and 4, and a bottom 5, extending downward to form an "annular collar or rim 6, i which rests the'device on the 1cm 7. lhe

' .refrac tor sides 1 and 3 are made up 0 tin walls and 9 cndthe sides 2 and 4 of frames 10 and 1.1. The side 3 has a. rectangular slot 12 cut therein and in the framework 10 and 11 of sides 2 and i I slide glass ones 13. Cleats 14 hold the panes 13in p ace (see Fig. 3). They may be held in place in any other way. The wall 9 on side 3 is in the form ofe, hinged hood which moves in and out on hinges 15 (see l ig. 2). In the framework 10 on side 4 in the top crosspicce'l cut a, slot 16, serrated or notched at 17. On the hinged hood or side piece 3 I fasten a lever or arm 18 at a point 19 and at its loose end this arm 18 carries a pin or finger 20 (see Figs. 2 end 5). In

moving the hood or side 3 in and out the arm 18 is raised and the pin 20 released from 0 the notches 17 and when the desired.inclina tion of the hinged side or hood 3 is attained the lever arm 18 is dropped and the finger 20 rests in one of the notches 17 and thus the hinged side is held in proper position, the pugs 21 of the side or hood 3 keeping in the 111 the side 3, I provide a T shaped slot 22. A shifter 23 is rovided and fits over the rectangular slot 12,011 the inside, and this shifter-23 carries a bulls eyelens 24 and afinger or handle 25. Thisflnger or handle 25 works up and down in the T slot 22 carrying the shifter 23 with it, the bottom of the shifter 23 resting on the bottom 5 (see Fig. 3) except when it is desired to shift or move the shifter 23 up and sidewisc; in that case the finger 25 is moved up in the T slot 22 and the shifter 23 assumes a new position (see dotted lines in Fig. 3); in this manner the bulls eye lens can throw the rays into varying positions. The shade itself is a truncated pyramid in form and is marked 26 (see Fig. 1); it rests on the reiractor part of the lamp just described and its parts can he made to slide and interchange in the same manner, it desired.

it will readily be seen that by moving the hood or side 3, carrying the hulls eye lens, the bull's eye lens will be made to concentrate theilight at varying distances from the light or lamp, and this adjustment can he carried on to a greater, extent by sliding or moving the shifter 23, to which the bulls eye lens is fastened, up or down or sidewise (see dotted lines lf-ig. 3). it will thus be seen that almost any point desired can be reached by these adjustable features.

' The panes of glass 13 may be plain or colored and are of the contour shown by big. 7. On the side 2 in lig. ,f%" the pane 13 is shown removed.

I may adjust the hood or side 3 in any other specific manner, as well as the shifte1 23.

.At its topedge the frame of the rei'ractor extends out in the form of a flange 27 and the urpose of this flange is to keep any light i 'om escaping at this meeting edge, between the shade and I'Gfl'zLCtOl'. instead of using glass panes part of the reiraotor I may use opaque slides or Walls. The shade may be made of any other form or contour and out of any suitable material.

What I clainias new and of my invention and desire to secure by Letters Patent is:

1. In a lamp shade and refractor, a frame work, said frame Work bein partly made up of sides, some of the sides eing capable of being slid in and out of the frame Work, one of the sides beii'ig movable, a bull's eye lens, said bull's eye lens'being attached to said movable side and means for adjusting the bulls eye lens to varying inclinations, in combination with means for shifting the bulls eye lens vertically and horizontallyas set forth.

2. in a lam shade and refractor, a truncated pyramid made 11 of a frame Work and sides, some of the sides icing removable from the frame work, a'hinged hood comprising one of the sides of the pyramid, the hinged hood being provided With a slot, a shifter plate, a bulls eye lens, said bulls eye lens being attached to said shifter plate and said shifter plate being attached to said movable hood, and a finger on said shifter, said bulls eye lens being capable of being moved with. said shifter, toassume varying positions in the hinged side, as set fortl Cincinnati, Hamilton county, State of Ohio,
