IMPROVEMENT IN STREET-LAMPS.

To ALL WHOM IT'MAY ooncs'nn:

Be it known that, I, THOMAS T. MARKLAND, Jr., of the city and countypf Philddelnhiayund State of Pennsylvanio, have invented a newand useful Improvement in Street-Lamps and other lamps; and I do hereby declare that the following is s full and exsct description thereof, reference being had to the accompanying drawings, nnd'to the letters of reference-marked thereon.

The netiire of my invention mainly consists in constructing street-lamps with name-plates in the main body of the lamps, but separate and distinct from the large glass plates, so that if the plates break, the name is still retained, as will be understood by the following description. .In the accompanying drawihgm which make a. part of this specificatidn- Figure 1 is a. plan or top view of the improved lamp.

FigureZ is a front elevation of the some.

Figure 3 is snedge v ew of the side frame A.

Figure 4 is a face view of the inside of the same.

Figure 5 is a perspective view-of the-conical reflector J.

"Figure 6 is top vie of a frame. to come see. modification in place of the parts 2 of the frame A A A and door D. v

Figure 7 is a side elevstion of the same.

Like letters in all the figures indicate thesame parts.

The main frame of the lamp is composed of the sides A, A, and A, and the crown B. The side frame A has flonches a d, by means of which it is secured with screws or rivets to the frames A A. The crown-piece B, which is made of sheet metal, has turned edges b b, which fit over the flanges c c of the sides A A, and are confined thereto by means of screws or rivets. The said frames A, A, and A have an angular turn from the main part 1, so as to form vertical parts 2 from the cross-rails d upwards, to receive the nsme-plute'C, for designating the streets, which plates are inserted in the verticelond bottom groove e. In the part 1 of the said. side frames the glass panesfare confined inthe rebates g, in the usual manner. The frame A is represented in detail in figs. 3 and 4. The frames A A are of similar construction to that of the frame A, with the exception of their flanges c c. The door D is of similar construction to that of the sidcsl'A A, but may be made without the part2, which may be a separate piece, confined to the sides A A by meens of bolts or rivets. The bottom plate E is confined to the flanges a of the side frames by means of screws or rivets. The neck- F-of the lamp is represented as made of sheet iron. It is confined to the-flanges h and ii of the crown B by means of bolts or rivets. It may be made in separate pieces, when desired, of caster sheet metal. There are namepletes G in the small doors H of the neck, stench side of the some. The doors are used as a. convenience in cleaningthelamp. The light is transmitted to the name-plates G from the interior of the lamp, through We openings 1' in the neck F. The names in the'platee G and G ore made by perforations, endure covered by,

glass-plates C and G, as represented in the drawings. They may. however, be made on the face of theglnss, or other plates, and arranged as described, or attached to the body of the lamp by means of books, Orin any other convenient manner. v The neck F may be of larger proportions, for the transmission of increased light, when the name-plates are not wanted in it. When the lamp is at the corner of two streets tit-right angles with each other, the name of each street is on parallel sides of the lamp, so as to be read in going either way.

Instead of the parts 2 in the side frames A,.A, end A and door D being'vertical, they may be in line with the parts lfwhen desired. The part Z may also be made separate from the part 1, in a single piece or in sections, and may be adapted to globe-lamps, for streets or stores, by providing it with a ring, O,- as represented in fige..6 and 7, which .ore on a diminished scale. The neck in this case may be either with or without n. cover, and with or without a hot-air tube. The part 2, constructed as just described, may be udnpted to the ordinary street'lzunp by dispensing with the ring 0, and connecting it by means of belts or otherwise to them-sin frame of the lamp, outside of the glass, so ns to come either above or below the junction of the upper and lower frames. The sliding perforated plates may be dispensed with by perforating the sides of this pin-t 2, nnd also tho sides of the neck 1 I iehthe roof of the lamp. It: is connected bymeans of rivets to the strips j of the neck F. J is a cenidal reilector'aronnd'the gas-pipe K It has a. slot; is. es seen iii-fig. 5, for the convenience of slipping it over the said-pine to remove it for cleaning. There may be a. piece of send-paper confined to the inside of the reflector for lighting matches; or the eiirface may be otherwise roughened. The inside of the crown 13 serves form, reflector for the upper part of the lamp, but there may be separate reflectors attached thereto, in any convenientimanner, so as to be readily detached for cleaning. L is the chimney, and Mthe roof of the same. There is a slot, Z, in the tube N, which projects from the lower side of the bottom plate E, for confining-tho lat'np-t0 the post. The latter has a'lug, o /er which the slot lie slipped, so its to keep the lamp from being turned 011% of its true position with the streets. v

What I claim as my invention, end desire-to secure by Letters Patent, is-

1.. The combination of na'me-plntesO with the frame of't'he lump, separate from the main panes of glass or the body of the lnmp, whebher, of square or other form, snbstantiallyin the manner above described and for the purpose set forth. I

2. lhe combination of the name-plates G with the neck F of the iamp, substantially as described nml for i the purposefsp'ecified.

3. The combinatio-rr of a glass neck with a street-lamp, the said neck being constructed either with omvithout' name-plates, substantially as and-fer the purpnsesebove described.

4. The combination of the slot l'ofithe tube N on the bottom plate E, with a corresponding lug. on a. a lampriost, substantially describednnd for the purpose set forth.

5. A sectional lump, constructed snbsteutielly as; described and forth; purpuees 'spccifie:l.

Intestimony that the above iqiny invcntion,I have hereunto set myhemlund offixed 1ny. senl, this 23d (loy ofiVIarch, 1867- THOS. T. MARKLAND Jar Witnesses:
