REFLECTOR.

SPECIFICATION forming part of Letters Patent No. 231,602, dated August 24, 1880.

Application filed J annary 2, 1880.

To all whom it may concern:

Beit known that l, MONTGOMERY O. MEIGS, of Washington, in the District of Columbia, haveinven ted certain new and useful Improvements in Reflectors, (Case 0 and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters ot'ret'erence marked thereon which form a part of this specification.

This invention relates to an improvementin reflectors shown in PatentsNos. 209,178 and 209,576, granted to me, having for its object to improve the construction and operation of the same; and it consists in the combination and arrangement of parts, as will be hereinafter more fully set forth, and pointed out by the claims.

In the annexed drawings, which fully illustrate my invention, Figure 1 is a front elevation, and Fig. 2 is a bottom-plan view, of a reflectorembodying my invention. Fig. 3 is a vertical section as applied to a gas-burner. Fig. at is a vertical section as applied to a candle. Fig. 5 is a similar section as applied to a students lamp; and Fig. 6 shows a view, in vertical section, of the device constructed in cheap form.

A represents a reflector, which may be of conical, ellipsoidal, paraboloidal, or hyperboloidal form, having in its bottom a slotted opening, a.

B are spring-standards, bent in the form shown, their upper ends passing through openings b in the sides of the reflector. The ends of the standards pass through sleeves c 0, arranged over the openings 1) on the inside of the reflector. One of the ends of this standard passes through the reflector and through a sleeve, (1, on the outside thereof, said end being also provided with a screw-thread, 6, adapted to receive and hold aclamping-nut, f.

0 represents a collar, of any desired form, adapted to receive a burner, lamp-chimney, or candle, upon which the reflector is supported.

The reflector being pivoted upon the standards, any desired angle may be obtained, and said an gleretained by the friction of the clam ping-nut.

In the drawings I have shown the pivoted reflector as applied to different lighting devices.

Fig. 3 shows the device applied to a gasburner, the burner being passed through and secured to the collar 0. A laterally-extending curved arm, g, is attached to the collar 0, the point of which rests against the inner side of the reflector and prevents it assuming an angle that will bring the flame in contact with the reflector. In addition to this a chain, h, is attached to one side of the reflector and provided with a book, i, adapted to be attached to a ring, j, on the burner-pipe, which is also used to limit the position of the reflector, as desired.

Fig. 4 shows the device as adapted to be applied to a candle, having an opening, it, in one side of the reflector to admit of the body passing through when the said reflectoris being adjusted to the desired position.

Fig. 5 shows the device as adapted to be applied to German student or other lamps, the construction being substantially the same as the device for the candle-reflector, with the exception that the collar (3 is enlarged.

Fig. 6 shows the device as it can be constructed of a cheap form, the form remaining the same.

By this arrangement it will be obvious that the application of the device to the} many lights mentioned will cheapeu the cost of production of said lights, and at the same time render them more brilliant.

The improvement inthis device over the patents hereinbefore mentioned is, that the reflector, being pivoted upon the standards, may be tilted to the desired position to reflect the light, and'held in position by means of the clamping-nut, whereas in the patents mentioned the reflector was not capable of adjustment out of the angle shown, but reflected the light in one direction only. I

The device is simply and economically construeted, and is not liable to get out of repair.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is y i 1. Thereflector A, pivoted upon standards B, arranged inside said reflector, and provided with a collar, 0, in combination with the clamping-nut f, whereby the reflector may be In testimony that I claim the foregoing as adjusted to the desired angle, substantially as my own I have hereto affixed my signature in 10 specified. presence of two Witnesses.
