S U. m a l- Patented Feb. 24.1874.
FIG.S
CHAUNCEY M. MURCH, OF CINCINNATI, OHIO.
Rnb q IMPRovEMEN-r |N LAMPS. ililil C To all whom it may concern:
Be it known that I, CHAUNGEY M. MUROH, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Lamps and Lanterns, of which the following is a specification Ihis invention relates to a lampA or lantern having a peculiar combination of mirrors for reflecting fore and aft in 011e long line, on which the light is concentrated, for illuminating street-ears, long corridors, passages, tunnels, Ste. The invention consists, primarily, in two pairs of vertical mirrors, each pair arranged in V form, and united at its apex, in combination with a single burner, arranged between the apexes of the mirrors, as hereinafter more fully described. The invention consists, further, in certain supplemental mirrors for preventing dispersion.
Figure l is a perspective view of a lamp or lantern embodying my improvements. Fig. 2
is a vertical section of the same at the line X X. Fig. 4 is another vertical section at the line Y Y, with a portion of the lamp proper broken away; and Fig. 4 is a horizontal section at the line Z Z.
A represents a rectangular frame or cage, to which is hinged, at c a', two doors, B C, having glass or other transparent panes b c. These doors may be maintained in their closed condition by spring-clips D, that are secured to the under side of the frame A. Securely tted within the frame A are two pairs of vertical mirrors, l 2 and 8 4, each pair being united in V form, whose outer orV reflecting surfaces maybe either flat or concave, although the latter is the preferred shape.` These two pairs of mirrors do not touch each other, a
space or interval, E, being interposed between the apcXes thereof, and it is within this open space that the burner F is located. The burner F, from which the light is emitted, may be arranged for gas, coal-oil,.or other illuminating agent, and it is preferred to use a broad, iiat liame, whose plane is coincident with the common axis of the mirrors. This arrangement ofthe burner is clearly seen in Fig. 4. If coaloil or other burning-fluid is used, the receptacle G for the same may be provided with a tongue, g, adapted to engage with a loop or staple, lll, that is securely attached to the frame tion forming part of Letters Patent No. 163,960, dated Fibzuary 24, 1874; application filed August 15, 1873.
A. I is a chimney, to allow the escape of smoke from the burner F, and also to conduct heated air away from the interior ofthe lantern. J and K are reiiecting-plates, secured, respectively, to the inner sides of the top and bottom of the frame A.
The 4mirrors l 2 and 3 4 may extend vertically from the plate K up to the plate J 5 but it is preferred to join said mirrors to elevated reflectors L L', as more clearly shown in Fig. 2. By referring to this illustration, it will be seen that these elevated retlectorsL are slightly concave, and curve over from the mirrors l 2 and 3 4 toward the front and back of lantern. The inner ends of these elevated reflectors are joined by flat plates Z l. M `are customary openings, to admit a supply of fresh air tothe interior of the lantern.
From the above description, it will be seen that `the rays of light proceeding from the burner F are projected upon the mirrors l 2 and 3 4, from which mirrors they are .reflected in opposite directions.
The arrangement of plates J KZ l and elevated reflectors L L serves to concentrate and prevent the dispersion of any of the rays, and consequently my lamp affords an unusuallyT brilliant light with a moderate consumption of oil or other illuminating agent.
The lantern will be found especially advantageous for street-railroad cars, as the rays projected from the front of the lamp will throw light upon the platform, while the rearward reilection from the same will thoroughly illuminate the interior ofthe cars.
It will also be useful in halls, streets, and other long and narrow passages where it is necessary to' throw light lengthwise of the same, and where any lateral dispersion of the rays is not needed. YVhether employed for cars, halls, or street-lamps, or other purposes, the advantage of reflecting light in two oppov site directions from a single burner will be obtained, and on this account thetrouble and expense attendii'lg the use of the two lamps for accomplishing the same result will be obviated.
I am aware that a four-way reflecting-lamp has before been devised. rIhis, therefore, I do not claim.
I claim as my invention- 1.
