The remote end 48' of the actuating member 32a is reversely bent and is terminally pointed to seat firmly upon the milled surface 29 of the casing 2, while the near end of the member 32a is closely looped about the body of the member at 4|, bent upwardly and inwardly to engage itspointed terminus with the face of the casing 2 opposite the end 40. It will be seen, therefore, that the form of the invention shown in Figure l embodies an attachment, that may .be readily attached to'and removed from a fluorescent lamp starter of the type described. The

mounting of the attachment upon the casing also bears some resemblance to that shown in Figure-5 and described more particularly hereinafter.

The form of the invention shown in Figure 2 resembles that of Figure 1 as to its mounting upon the starter casing but is further characterized by the provision of an elongated and closed loop Mo on the actuating member which is easier to engage by a suitable hook attached to the manipulating rod referred to in the detailed description of Figure 3 when the starter is located on the end wall of the fluorescent fixture or on a side wall of. the fixture above the lamp as is indicated by the dotted outline of Figure 3. Herein, the

- remote end 40b of the actuating member is pointed to seat upon the milling 29 of thecasing 2, while the other end is bent about the body of the member at 4lb to provide the 100p 4!. The contact loop is provided as before and is slightly ofiset to engage the resetting button to relatch the starter unit.

In Figure 5 is shown a modifled form of my improved attachment in which the starter casing is recessed or perforated approximately diametrically thereof to provide a pivotal mounting for the actuating member. The perforations 42, 43 are made preferably near the upper rim of the dish-shaped cap I where the casing has been stifien ed in the forming process and wherein the ends 44, 45 of the actuating member are seated. A slightly offset loop 46 is provided as before to engage the resetting button 23 upon movement of the handle portion' 39a, as before. From the foregoing it will be observed that there has been provided an attachment for the starters of fluorescent lamps which is easily manipulated despite the inaccessibility of such starters on the lamp brackets, is easy to install and may be rapidly and inexpensively manufactured.

It will also be noted that due to the rather sharp radius of curvature of the button engaging portion, the actuating member will be normally maintained in its operative position, and will readily return to such position after movement of the handle portion to engage the resetting button. Thus, there is no possibility of the resetting button being maintained in its depressed or resetting position.

Iclaim: I

1. An' attachment for fluorescent lamp starters of the plunger operated, manually reset type comprising a substantially flat bridge member bent into the shape of a U having a central portion extending laterally over said plunger and .im

wardly facing, curved terminal portions for gripping the starter casing and longitudinally spaced bearing surfaces in its intermediate portions, and a rod-like plunger actuating member extending laterally of said starter subjacent said central portion of the bridge member and pivotally mounted in the bearing surfaces of said bridge member, said actuating member having a central deformed portion movable to reset said plunger in one position of rotation of said actuating memher.

2. An attachment for fluorescent lamp starters having an axially extending plunger of the manually reset type comprising a generally flat bridge member overlying said plunger, means for securing said bridge member to said starter, and a plunger actuating member having a handle portion extending in parallelism with the axis of said starter and an integral, transverse portion in parallelism with said bridge member and pivotally mounted on said bridge member in spaced relation from said plunger and movable into contact therewith upon rotation of said handleportion.

3. An attachment as defined in claim 2 wherein said transverse portion is laterally offset from said bridge member for the major portion of its length.

4. An attachment for fluorescent lamp starters of the plunger-operated, manually reset type comprising a single, elongated member bent intermediate its ends to provide a reinforced handle portion, an inwardly bent, remotely disposed, starter-engaging terminal portion, a similar terminal portion spaced from said handle portion and an intermediate portion movable into contact with said plunger.

5. In a fluorescent lamp fixture having a socket for a lamp starter mounted therein, and a pair of sockets so mounted as to provide substantial obstruction of the starter by the lamp when rested therein, an attachment disposable over said starter and operable from a position laterally oil'- set from the position of said lamp, said attach ment comprising an elongated rod-like member pivotally mounted relative to said starter, an integral handle portion extending from said rodlike member, and a central laterally offset portion selectively movable into and out of engagement with said starter upon rotation of said handle portion.

6. An attachment for fluorescent lamp starters of the plunger-operated, manually reset type comprising a single, elongated member bent intermediate its ends to provide a closed loop, handle portion, an inwardly bent, remotely disposed,

starter-engaging terminal portion, a similar terminal portion spaced from said handle portion and an intermediate portion movable into contact with said plunger.
