Definitions
- A represents the body ot the reilector, made of tinned sheetiron or any other bright sheet metal, and which may be lined in the inside.
- the body A is that ot' an oblong truncated pyramid, the sides being inclined at angles ot about lorty-ve degrees, and an opening, a, in the top allows the necessary dratt of' air for the llames.
- a cover, B is attached to the retlector at a certain distance over thc opening aand this cover may be curved in such a manner that all the rays of light which may strike it will be reflect-ed down through the opening aI in the top of the body A of the rellector.
- the sides ot' the body A of the reflector may be perfett planes, or tney may be slightly concave at their inner sides.
- the cover B instead of hobos curved, may be a plane surt'ace, it' desired, but the curved surface would be preferable.
- the body of the reilector is 4provided with beads b b', near to its edges, and extending all'around. The object ot' these beads is to catch those rays of light which would otherwise escape over the edges of'the retlector. Rays ot' light e, infalliug over the flat surface of the reiiector, provided the sides are planes, would be Areflected in the direction indicated by the dotted lines,but by means of the heads b b they are reflected down in the directionl indicated by the line cx.
- the beads b b' besides performing the above function, serve to strengthen the metaland to give to the whole an .ornamented appearance.
- this hinged section is brought in a vertical position, and it' it is desired to direct more light to the goods immediately under the r1 ne( tor, the hinged section is tui'lzel out so as 1o l e in line, or n( arly so, with the side of the releetor to which it is attached.
- This hinged section serves at the same time to protect the eyes of persons look ing in from the outside, and it can be attached without materially increasing the cost of the Whole reliector. The effect ot' these retlectors is unsurpassed, and a large quantity ot' the saine have already been sold by me in this city and in other places during the last twelve months.
