" 1 Claim. ('01. arc -102) This invention relates to protecting devices for incandescent light bulbs commonly referred to as lamp guards. Such guards are commonly used-t0 prevent damageto orbreaking of electricylight bulbs particularly in places-where such bulbs are 1 subjected to abuse,wsuch as in machine shops, factories etc. J

y Lamp guards as such are .well known, but. are defective in important details which the presen invent-ion intends to overcome. a

With this: in view, it isthe p'rihcipalobject of the present invention to provide ,a lamp-guard which is attachable to an electric: light bulb socket before the bulb is inserted and which permits the removal and replacement of bulbs with-l out necessitating the removal andreplacement of the-guard. q. I.

A further feature of the present invention'lies in the provision of means to permit the attachment of the guard tosockets of diiferent thicknesses. 3 I 1 A still further aim of the present invention resides in. the provisionof hingedlysecured means formed from .a single strand of wire:to permit access to the interiorof theguard for the purpose of removing and replacing bulbs.

.It is a still further purpose of the present invention to provide .a lampguard which may be attached to the. socket of, an electric light bulb without the necessity ,ofremoving the bulb prior to the attachment of the guard, all of these features representing a saving of time and labor.

And it is yet another purpose of the present invention to provide a lamp guard of this character, which may be attached to any standard socket in a simple and rapid manner, without requiring the use of tools other than a ,screw driver, and which is relatively inexpensive to.

manufacture.

These and other meritorious objects and advantages, which will become more fully apparent as the description hereof proceeds, are achieved formof lamp guardshownin an Figure 4 is a top plan view of a modified form of lamp guard, closed.

Figure 5 is a sectional view, on line 5+5 of Figure 4, theguard here illustrated as being open.

parts being broken away. a

Figure 7 is a front elevational view of the modified form illustrated in Figure 6.

Referringin greater detail to the drawings, the

lamp guard comprisesinthe principal embodiment illustrated in Figures 1, 2 and 3 of the drawings,ztwosubstantially oval shaped straps Ill and a II. The end of eachstrap is provided with a lateral extension as at l2, I3, liandlfi. Said extensions, in the center thereof, areyprovided with circular bores I 6 through the opposing pairs .of which pass set screws l'lfor a purposeto be by the novel construction,combinationand arrangement of few and simple parts, hereinafter described and illustrated in the accompanying drawings, forming a material component of this disclosure, and in which Figure l is a top plan view of the principal embodiment of the present invention, the door shown in closed position.

. thereof through each opposing pair of which may .pass set screws 33 for a purpose which will be presently xdescribed. i i l l A:p1urality of substantially vertical wire members 18 have dneof their ends secured by solder- 3 ing or otherwise to the outerfaces of straps H3 and ll,'as at 19, theirother ends being'soldered or .otherwise secured, as'at 28 to a wire ring 2!. Parallel wires lBare socurved as to form. sub- To permit access to the interior of the guard as is necessary for instance, when it is desired to exchange bulbs within said guard, a door is provided, said door being made from :a unitary strand of wire, curved to form two. parallel side members 2|, which, at their. ends are looped about base ring 2|, and are thus hingedly secured to said base ring as indicated inthe drawings at 22. Between said spaced apart parallel sides 2!, the wire is bent substantially rectangularly with respect to said sides 2! and downwardly to form gripping andlocking member 23. Parallel sides 2| are held in place by spread ring 24 and vertical wire members I8 are held in place by spread ring 25.

The modified form of lamp guard illustrated in Figures 4 and 5 comprises two substantially circular straps 3!] and Si each of which having a lateral extension at each end, as at 32, Each lateral extension has a circular bore in the center presently described.

wire members 34, the said wire members being curved to form a cage, the diameter of which is smaller near

straps

30 and 3| than it is at the lower ends of said wires 34, so that a bulb may be conveniently placed therein. At their lower ends, wire members 34 are secured by soldering or otherwise to a base ring, comprising two

semicircular wire members

35 and 36, their ends looped for engagement with each other to form hinges 31. Substantially at their center, wire members 34 are held in plac by a retainer ring looped about base ring 36 to form hinges 42, the

front of said door being curved substantially rectangularly with respect to side members 40 and'downwardly to form a locking and fingergripping member 43, the side members 40 being held in place by a spread ring 44 to which they may be secured by soldering or otherwise.

The modified form illustrated in Figures 6 and 7 comprises two substantially semi-circular straps 50 and each end of which is provided with a lateral extension 52, each of the lateral extensions being provided substantially at the center thereof with a circular bore 53 for the passage of set screws through each opposing pair of said openings.

Secured at their upper. ends by soldering or otherwise to straps 50 and 5| are a plurality of substantially vertical wire members 54, their lower ends being secured by soldering or otherwise to a base ring comprising two

semi-circular members

56 and 51, hingedly looped at their outer ends for engagement with each other as shown at 58. Substantially at their center, wire members 54 are held in place by a retainer ring comprising two substantially

semi-circular wire members

59 and 60, their outer ends looped for engagent with each other to form a hing 6|.

To permit access to the interior of the guard, there is provided a door made from a unitary wire bent to form two spaced apart parallel side members 62 looped at their respective ends (not shown) about

base ring

56 or 51 to form a hinge, the front portion between said parallel Wires being curved substantially rectangularly with respect to said parallel wires to form a locking and,

' into its socket, the set screws in the extensions of the straps are loosened to whatever width may be required to permit the straps to clear the base of the socket. The screws are then tightened and the guard will be in place. This is done whichever of the three forms here described are employed. Once the guard has been put in place, it need not again be removed for the exchange of bulbs or for any other purpose,'except if it is desired to remove the guard.

Thus there has been illustrated and described a lamp guard in three of its preferred embodiments, but this disclosure is not to be regarded as limitative or restrictive to the exact details shown, but rather as descriptive and illustrative of these embodiments and it is to be understood that such changes and modifications in the construction of the device may be made as may come within the scope of the appended claim, without I thereby departing from the spirit of the present a plurality of spaced-apart parallel vertical wires,

a top portion, said top portion comprising two arcuate straps, one end of each of said wires securedthereto, a base, said base comprising two arcuate wires, the other end of each of said vertical wires secured to said base, said top, vertical wires and base constituting a cage-like structure, and a door for said cage-like structure, said door formed from a single strand of wire shaped to form two spaced-apart parallel side members, the ends of said side members hingedly secured to said base, and a gripping element formed at th upper end of said side members.
