It is noted that the free slidable end 33b of the Having described our invention, what we claim spring 33 is disposed near the jaw l5 so as to the rigid member 29 is pivotally moved in a clock wise direction as viewed from Fig. 1 and 3, it will as new and desire to secure by Letters Patent is: exert its pressure in the area of the said jaw l5. ' 1. A ?uorescent lighting ?xture servicing im In order to be able to effectively use the appli plementcomprising a ?rst spring arm and a sec ond spring arm constituting a pair of substan ance of our invention from the floor without hav ing to employ step ladders or chairs or stools, we mount the base support I2 for the arms I70 and II, on a suitable hub member 36 to which there is attached a long rod 40 of any desired suit tially vertically disposed spring arms normally spaced apart, a relatively long handle, a support for said arms disposed at one end of said handle so that the upper ends thereof will be free, an arcuate jaw member ?xed to said free end of each able length for the convenience and-e?iciency. To pivotally move the rigid member 29 as above described in a clockwise direction to close the jaws I4 and I5 we provide the rod 40 with a pair spring arm, said jaw members being in opposed relationship and adapted to clamp and hold be tween them the elongated glass tube of said fluo rescent lighting ?xture when said spring arms are urged towards each other, and means for causing said spring arms to move toward each other, said last named means comprising a substantially hori zontally disposed rod member having one end of spaced ?xed bracket members 42 and 43 through which we slidably pass another rod 50, the upper end 50a ‘of which is outwardly angu larly bent, as shown. The said end portion 500. of the rod is pivotally attached to an outwardly angularly bent and forked portion 60 of the rigid member 29 by means of the pivot 55. Any‘suit able handle may be provided at the lower end thereof pivotally mounted on said ?rst arm and the opposite end passing freely through an open- of the rod 50. For convenience we have shown a 30 ing in said second arm, an abutment on said rod member, adjacent the free end thereof, an ex lever 51 pivoted at one end to the rod 40 by the tending bracket portion on said support, a sub; ‘pivot 58. The lever 51 is provided with a slotted stantially vertically disposed rigid member piv-_ opening 59 and the rod 50 is attached to the lever 51 by means of a pivot 6| operating in the slot 59. It is thus seen from the above description that when it is desired to close the jaws l4 and I5 it is’ merely necessary to grasp the lever 51 and turn otally mounted at the lower end thereof on said bracket and having an opening adjacent the upper free end thereof through which said horizontal rod member freely passes, said upper free end of said rigid member being disposed between said the same in a clockwise direction to its dotted second arm and said abutment, so that pivotal’ movement of said rigid member in a direction line position 51'. ‘This will slidably pull the rod 50 downwardly to pivotally move the arm 29 to close the jaws l4 and 15. f .A set screw 88 carried by one of the brackets 43 may be employed to lock the rod 50 in any desired position. ‘ toward said abutment will cause the resilient , It is often necessary, when servicing ?uorescent lighting ?xtures, to remove and replace defective movement of said ?rst arm toward said second arm. . 2.

To this end, we have incorporated, in our appliance, the following means whereby to readily remove these defective starters without using step ladders, chairs or stools and at the same time that defective tubes are being replaced. Attached to the bottom end of the rod 40 is a cylindrical member 10 which is preferably made resilient material to prevent injury to the said glass tube during the clamping action. of rubber or the like resilient material and which 4.
