' HAND PORTABLE ELECTRIC LAMP.

Application led .Tu-1y 5,

My invention relate's'to hand tric lamps. Y

@ne of the objects of my invention is to provide an improved ha-nd portable lamp having nov exposed metalV parts whereby it Vcan be used safely around apparatus having exposed live parts.

A further object of my invention is to provide an improved hand portable Vlamp which will be simple, compact and efficient.

. A .further object of my invention is to provide improved means for attaching the bars forming the lamp guard.

Afurther Obj-ect of my invention is to provide an `improved hand portable lamp provided with a switch. y A further object of my invention is to provide improved means for holding the switch socket mechanism in place in the handle.

Further objects will appear from the description and claims.

In the drawings in whiclran embodiment of my invention is shownp Figure 1 is an axial section through l.the hand portable lamp;

F 2 is aview looking down on thelamp;

Fig. 3 is a section on the line 3-3 of Fig. l; Y y Y Fig. l shows a detail of the supporting hook; l

Fig. 5 is a side elevation of the lamp;

6 is a section on the'line 6-6 of Fig. l;

Fig. 7 is a section Fig. l; and Y Fig. 8is a detail view 'showinghow the Aguard bars are secured to the Outer ring.

Referring to the drawings in detail, the construction shown comprises a handle 10, a lamp guard 11 mounted on the handle anda switch socket 12 mounted inthe handle. The handle 10 may be of' wood or other suitable material.` It has an axial passage 13 portable elec on the line 7-7 of for the feed wires leading to the socket which is seated in an axial recess 1K1. The socket is held `in place in the handle by means ofl the push bar 15 of' the switch mechanism, which push bar extends transversely through the socket and through the` openings 16 in the handle. The push bar is readily detachable from the socket so that to remove the socket it is only necessary to remove the push bar laterally through one of the openings 16, thus releasing the socket the washer 28.

and vpermitting it to be removed from the recess Min the handle. The switch socket comprises an insulating base 17, shelland center contacts 18 and 19 and switch mecha- D ynism 20. The switch mechanism includes theoscillatable switch arm 21, a pair of contact members 22, v'(the circuit between which is controlled by the oscillatable switch arm or bridging member 21) and the push bar 15 referred to above which controls' the operation of the switch arm 21. The center Contact 19 and one of the switch contacts 22 are formed as parts of an integral stamping secured to the insulating base 17 by means of an eyelet 23. The Aother switch contact is electrically connected with one of the binding terminals.v The shell contact 18 is electrically connected withtheother binding terminal. The switch mechanism thus con trols the circuit between one of the binding Vterminalsland center contact, effecting a in Fig. 8. `The inn-er ends of4 these bars are brought together in `pairs as Vindicated in Fig. 3, and arefsecured to the flange portion l26 of the handle by means of rivets or eyelets 27. There is one rivet for each pair of bars. This rivet lies between the bars of the pair and is provided with an insulating washer 28.,.at its Outer end, the rivet or eyelet extending vthrough the flange'portion 26 between the bars v2li and through theinsulating" washer 28v and being riveted over at one yend on the flange 26 and 'at its other end on i The edges of the bars are notched as indicated at 29 to receive the vwasher, and the upper vand lower edges of the washerare notched as indicated at 30 to rece-ive the edges of the bars.

In assembling the guard, the .bars are hooked into the Outer retaining ring and are then sprung inwardly and fitted into the notches 31 in the flange 26, after which the eyelets 27 are rivetedover to secure the bars in position.

In Order to steady and yieldingly support the lamp bulb 32, a plurality of spring iingers 33 are provided, the tips Stof which fulcrumed, and retainedin place bythe lbar 15. The engagementof these spring lingers 34 with the lamp bulb is v`such as to urge the ybulb outwardly against the holding action of th-e bar l5.

, The insulating hook 35 may be formed of a pair ofk fiber stampings-SG, lriveted .together as indicated at 37, and riveted to a pair of thebars 2% is indicated at V38.` The twomembers of the hookare spreadapart and extend'through holes 39 in the retaining flange 25 to hold the hook in proper position.

A glare shield L.LO may be provided for protecting the eyes from the direct rays from the lamp. This glare shield maybe of .insulating material as sheet liber bent to conform to the inner edges of the bars 24., In order to hold this glare shield in place, lugs al are struck up from the iiberforengagement with a pair of bars 24. i y

lVhile, I have shown but one f-'orm of my invention, itis to be understood'that Ido not desire to limit myself to this particular construction since many changes andmodilicationsI may be madetherein `without departure from the scope of thefollowing claims. i ,Y
