UNITED STATES PATENT OEEIGE.
THOMAS T. MARKLAND, JR., OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN'NAME-PLATES FOR STREET-LAMPS.
Specification forming part of Letters Patent No. 76,334, dated April 7, 1868.
To all 'whom it may concern Be it known that I, THoMAs T. MARKLAND, Jr., of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Name-Plates for Street-Lamps, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consists in the construction ofthe name-plates of street-lamps with block letters which have open spaces between them. y
The invention will be understood by the following description.
In the accompanying drawings, which make a part of this specification, Figure l is an isometrical view of a street-lamp with the improved name-plates in connection. Fig. 2 is a like view of a name-plate adapted to the inside of a lamp. Fig. 3 is a view of one of the letters on an enlarged scale, with perforations to lessen the obstruction of light from the lamp.
Like letters in all the figures indicate the same parts.
A is the lower part of the combined frame of a street-lamp, and A the upper part ofthe same. B B B B are the name plates or frames, which contain the names of the streets where the lamp is located. The letters have open spaces between them, as represented, for the transmission of light from the lamp. Two of the frames, at right angles to each other, have the names of two streets which cross each other where the lamp is located-in the present case, Chestnut street and Fourth streetand the frames parallel thereto have, respectively, the saine names, so that the names of the streets may be read in passing either way. The names are formed of block letters, which are held in place by the sides a of the frames. The frames are riveted together at their ends, so as to form a combined frame, whose lugs b rest on the flange c of the lamp-frame. The frames B, either separate or combined, may
be placed in any attitudinal position by suspending them by means of hooks or otherwise; or they may be otherwise attached, to suit the views of the constructor, and roofed to keep off the snow.
It will readily be seen that the names thus Aformed give but slight obstruction to the light transmitted from the burner.
A further improvement in the transmission of light may be effected by perforating the letters, as represented in Fig. 3.
The name-plates may be made either of cast or sheet metal, or of any other suitable material.
Fig. 2 represents a section-plate adapted to the inside of the lamp. It may he screwed or riveted or otherwise secured to the main frame, the frames B being either fastened to gether at their ends or left separate.
If desired, the letters may be covered with glass plates, colored or plain, slipped in grooves or otherwise secured. The letters should be of such a color as to contrast with the glass plates. Isinglass may he used instead of glass.
Instead of arranging the name-plates inside or outside of the lamp, they may be made to constitute a part of its main frame.
For globe-lamps the name-plates may be either straight, as represented, or circular,-
corresponding to the shape of the lamp.
I have represented the name-plates on a lamp at a corner of two streets; but they may be advantageously used in other locations to designate stores or other buildings.
That I claim as my invention, and desire to secure by Letters Patent, is-
The name-plates B, in combination with street-lamps, constructed and arranged sub stantially as described.
In testimony that the above is my invention I have hereunto set my hand and affixed my seal this 23d day of November, 1867.
THOS. T. MARKLAND, JR. [L s] Vitnesses:
STEPHEN UsTroK, JOHN WHITE.
