STREET-LAMP.

SPECIFICATION orming part of Letters Patent No. 379,265, dated March 13, 1888.

Application filed February 19, 1887. Serial No. 228.268. l\`o model.)

To aZZ whont it nuty concern;

Be it known that l, MARTIN L. BEST, acitizen of the United States, and a resident of Oanton, county of Stark, State of Ohio, have invented a new and useful Improvement in Street-Lamps, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in street-lamps; and it consists in providing a glass-holding frame comprising the parts-and combination of parts, as hereinafter described, and set forth in the claims.

Figure 1 is a View in perspectiveofastreetlamp embodying myimprovements; Fig. 2, an elevation of glass-holding strip, showing the first bend in the process of forming the strip. Fig. 3 is same view showing the second operation or reverse bend. Figs. 4 and 5 are views of the bottom strip. Fig. 6 is a View of a corner of upper section of lamp-frame. Fig. 7 is an elevation of a fragment of lamp-frame, showing the glass-holding strips in position. Fig. 8 is a View of a corner section of lamp-frame and glass-holding strip; and Fig. 9 is a view of a corner sectionl of lamp-frame, showing the frame as usually made and before the glassholding strips are applied.

Similar letters of reference indicate corresponding parts in all of the figures of the accompanying drawings.

As my invention relates more particularlyto the removable glass-holding strips, and is applicable to many of the well-known streetlamps now in use, I will proceed to describe my invention, referring to the lamp-frame or' parts thereof only when in conjunction or combination therewith.

Where street-lamps are constructed in such a manner as to require that the glass be secured therein by putty a construction quite extensively in use-the replacing of the broken glass will in a short time greatly disfigure, if not totally destroy, the facing strip or wing to which the glass is attached.

The pnrpose of my present invention is to provide improved removable devices for securing the glass to the lamp.

In Fig. 2 is shown aside strip, A, which may Vbe made of any suitable sheet metal. This and of such length as may be required.

The first operationin the process of formation is the cutting away of a portion, as shown at (L3, forming projection al. The edge gif' is then turned overon thestrip, as shown in Fig. 2, leaving a space or groove, a, of such width and depth as may be required, to receive the edge of the glass and hold the same in desired position. The next operation consists in folding the so-formed groove (L5 back on the strip, as shown in Fig. 3, and as thus formed the strip may be applied to the lamp-frame, as shown in Figs. 6 and Z, and the strip or Wing a passed in between one side of the groove a? and the back of the strip ai. The bottom strip, B, (shown by Figs. 4 and 5,) is of the same general construction as the side strip, the only difference being in the length, and that a portion of the plate is cut away froin about the center of each end, as shown, forming two projecting end Sections, d' and d, as shown in Figs. 4. and 5, one of which, dz, may be shorter than the other. The projected ends of the bottom pieces may embrace the ends of the Vertical strips, as shown in Figs. 7 and 8.

frame of the lamp they are passed over the edge of the wing a, said wing passing in between the glass-holding groove af) and the back of the strip az, as shown in Figs. S and 9, thus forming a continuous groove, a, on the outside of the lamp-frame down the sides and across the bottom, as shown in fragment of frame, Fig. 7, into which the glass may be placed by entering a groove formed for the purpose at the upper end of the frame, and sliding it down until the end rests in the bot', tom groove, andfrom which they may be removed for cleaning or for any other purpose.

The glass may be either slid up into the groove far enough to swing into position over the groove in the removable strip and then be slid down into said strip, or-it may be slid down through the groove in the frame into the groove in the strip. The groove in the frame holds one end or side in position, and the groove in the holding-strip holds the opposite end or side in position. There being no solder- In placing the glass-holding strips in the` strip is about one and one-fourth inch in width,

IOO

ing required in attaching the strips to the lamp-frame, they may beattached and detached'as oceasion may require.

The strips A are adapted for use in the top section of the lamp, as shown in Fig. 6, as Well as for the lower section.

As hereinbefore stated, these glass-holding strips may be applied to many of the streetlam ps now in use, and avoid thereafter the destrnctive and expensive use of putty. Having thus fully described the nature and object of my inventiomwhat I claim, and desire to secure by Letters Patent, is- 1. The combination, with the frame of a street-lamp provided with a glass-receiving groove in one of its sides and aninwardly projecting Wing on the side opposite to the groove, of arernovable glass holding strip provided With oppositely-faced grooves, one to receive the said Wing and one to receive the edge of the glass,whereby the glass may be secured by being slid into the groove in the frame and then slid into the groove in the removable holding-strip, substantially as set forth.

2. The combinatiomwith alamp-framehaving a Wing projecting inwardly therefrom, of the glass-holding strips, consisting of strips of sheet metal folded to form oppositely-facing grooves, one to receive the Wing of the frame and the other to receive the edge of the glass, substantially as set forth.

3. The combination, With the frame of a street-1amp provided With an inWardly-projecting Wing, of the glasseholding removable strip B, havinga groove, (L5, for receiving the edge of the glass, a groove between the side of the groove a5 and the back a2 for receiving the Wing on the frame, and endprojeetions, as d' d, as described, and' for the purpose set forth.

In testimony Whereof I havehereuntoset my hand this 17th day of February, A. D. 1887.

MARTIN L. BEST.
