CHAUNCEY M. MURCH, OF CINCINNATI, OHIO.
IMPROVEMENT IN REFLECTORS.
Specification forming part of Letters Patent No. 149,775., dated April 14, 1874 application iiled March 21, 1874.
To all whom it may concern:
Be it known that I, CHAUNGEY M. MURGH, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Reector for Lamps and Burners, of which the following is a speciflcation:
My device is designed for ready attachment to any ordinary gas-burner or lamp; and-com prises a pair of V-formed wings or reectors, which, being secured upon suitable wire supports or brackets, are capable of adjustment so as to divert the light in two opposite directions in equal or unequal proportions, or wholly in either direction, at will.
Figure 1 is a perspective View, showing my reflectors applied to a common gas-burner and set for directing the rays equally in two opposite directions. Fig. 2 shows the relectors applied to a coal-oil lamp, the wings being set to project the light wholly in one direction. Fig. 3 represents one of the reflectors detached from the supporting-bracket, a portion being broken away. Figs. 4 and 5 are plans, showing dierent positions of the reflectors.
A may represent a gas-burner, and B a kerosene-lamp-of common construction. C are sented V form in their horizontal section."
These two duplex reiiectors may be set so as to project the light equally in both directions, as in Fig. 1, or more largely in one direction, as in Fig. 4, or wholly either forward Aor backward, as in Figs. 2 and 5. Diagram Xshows one of the reliectors placed on its bracket in. reversed position. The retiectors may beso constructed that when thus reversed they will completely inclose the light.
I claim as new- The pair of V-sliaped reflectors D D', constructed with sockets d in the angles, and su pported adjustably on the brackets C, substantially as and for the purpose set forth.
In testimony of which invention I hereunto set my hand.
Attest: CHAUNCEY M. MURCH.
