I LAMP-GUARD.

Application filed. July-11, 1918, Serial No. 244,389,. Renewed June 26, 1919. Serial No. 307,043;

T 0 all whom it may concern: 7

Be it known that I, lVILFRiD 'LUMLEY, a citizen of the United States, residing at Conneaut, in the co unty of Ashtabula and State of Ohio, have invented a certain new and useful Improvement in Lamp-Guards, of which the following is a full, clear, and exact descriptions The object, of his invention it to provide a strong and durable but inexpensive cagelike guard for electric lamps. The invention consists in the construction and combination of parts shown in the drawing and here inafter described and pointed out definitely in the appended claims.

Inthe drawings, Figure 1 is a side elevation of a lamp guard which embodies the invention, and Fig. 2 is a bottom plan view thereof; Fig. 8 is a side elevation, partly in section, of a slightly modified form of such a lamp guard, showing in what manner it is removably secured to the lamp carrying fixture. Fig. 4; is a bottom plan view of the guard shown in Fig. 3.

Referring to the parts [by reference characters, 10 represents a base ring which is a part of the. lamp guard. This is formed with an internal screw thread, as shown in Fig. 3, to facilitate its application to and removal from a fixture 12 which carries the lamp 13, the latter being shown in dotted lines in Fig. 3.

. 15 represents guard bars, each being a flat bar of thin metal, preferably of brass. At its inner end each of these bars has an integral ear 16 formed by bending the metal laterally at right angles All of the ears 16 of the guard bars are fastened by screws or rivets 17 to the lower face of the base ring 10. There may be as many of these guard bars as desired. In the guard shown in Fig. 1 there are six of these guard bars, while in the guard shown in Figs. 3 and 4 there are only four of these bars, and each of them is a composite piece, as will be presently explained.

These bars when secured to the ring as stated all he in vertical planes which are radial to the axis of the base ring. The outer I ends of these bars 15 are curved in these radial planes toward one another. On the.

' guard bars.

edgewise in the arcof a circle, and each has at both ends the laterally bent ears 21 and each of these bars is of such length that when j placed between two adjacent guard bars 15 theseears will lie flat against said Screws or rivets 23', secure to Specificationof Letters Patent. gp t M5}; 11,1 2

gether two ears of adjacent brace bars and I the guard bar which lies between them.

Preferably there are two annular rows of these flat brace bars; but obviously any number of rows may be provided.

' In the construction shown in Figs- 3 and 4 four guard bars only are shown, and these are located 90 apart. In order to besure that ith ese four barswill be strong enough to withstand the misuse to which they are.

liable, each of these bars is made of three:

pieces, the two pieces 15*, 15 and the piece 15*. Thepieces 15 15?, are placed side by side and in contact at the point where they go between and are Secured'to the ears 21 on the upper row of brace bars 20. These two bars 15 15 ,are, however, spread apart adjacent the base ring '10; and each has an integral ear 16 secured to said base ring. These pieces 15 extend downward to the lower annular row of brace bars 20. Each of these guard bars below this lower annular row is formed of a single bent piece 15 the upper end of which goes between the lower ends of the two associated pieces 15*, and these go between the ears 21 of two curved brace bars 20. These five thicknessesof metal are secured together by screws or rivets 23.

It will be observed that the described" guard will be strong and capable of offering suitable resistance to blows applied to the outer edges of said bars. It will be likewise noted that the arrangement of the various bars is such that they offer as little obstruction to the passage of light from the lamp 13.

as possible.

Having descrlbed my inventlon, I claim: 1. In a lamp guard, the combination of a horizontal base ring a plurality of vertical flat guard bars arranged radially with re spect to a prolongation of the axis of said I ring,--each of said guard bars having at its upper end an integral laterally projecting ear which is fixed to the under face of said base ring, and each of said guard bars having its outer end curved toward a prolongation of the axis of said base ring and having an integral laterally bent ear at its lower end,which ears lie against and are rigidly secured to the sidesof adjacent guard bars.

2. In a lamp guard, the combination of a horizontal base ring, a plurality of vertical fiat guard bars arranged radially with respect to a prolongation of the axis of said ring,r-each of said guard bars having at its guard bars, a row of curved brace bars each having at its end an integral laterally .extendedjear, and each or said brace bars being of such'length that it will lie between the guard bars of an adjacent pair of such bars with its ears in contact with both of said bars, said ears being rigidly fixed to the guard bars with which they are in contact.

3. In a lamp guard, the combination of a horizontal base ring, a plurality of vertical fiat guardbars arranged radially with respect to a prolongation of the axis of said ring,each of said guard bars having at its upper end an integral laterally projecting ear which is fixed to the under face of said base ring and each of said guard bars havingits outer end curved towarda prolongation of the axis of said base ring, and hav ing an integral laterally bent ear at its lower end,which ears lie against and are rigidly secured to the sides of adjacent guard bars, a row of curved brace bars each having at its end an integral laterally extended ear, and each of said brace bars being of such length that it will lie between the guard bars of an adjacent pair of such bars with its ears in contact with both or said bars, and rivets or the like, each of which passes through and fastens together a guard bar and two cars formed respectively on the ends of two adj acent brace bars.

4:. In a lamp guard, a base ring, a plurality of guard bars extending substantially axially from the ring and secured thereto, the ends of the bars remote from the ring extending inwardly and secured together and a plurality of segment-shaped bars 1ying in planes substantially parallel to the base ring, each bar extending between and having its ends secured to a pair of adjacent In testimony whereof, I hereunto aflix my signature.
