Removing High Lamp Bulb 



H 



( )\\' circ l)urnt-(iui l)ull)s riMunved 

 in large c'li-ctrically-lightfd cano- 

 pies over 





the entrances of hotels, 

 theaters and public l)uildings? Ordinaril\- 

 a long extension ladder is 

 required. A man holds 

 the foot of the ladder to 

 firevent it from siip[)ing; 

 another climbs it to re- 

 move the burnt-out bulbs 

 and insert new ones. 



A simple de\^ice has 

 recently been put on the 

 market which is intended to be used on 

 the end of a long bamboo pole and which 

 enables one man with an ordinary ladder 

 to do this work. 



The device consists of three sleeves 

 carrving a set of metal tongues which 

 are bent in the shape of a bulb and 

 covered with rubber pro- 

 tectors for nearly their en- 

 tire length. The two end- 

 sleeves slide within the 

 middle one. The lower 

 sleeve is fixed on the 

 end of the bam- 

 boo pole by means 

 of a spread cotter- 

 pin. The lower ends 

 of the tongues are 

 joined to a disk held 

 in the upper sleeve 

 and joined to the 

 fixed bottom sleeve 

 by means of a coil- 

 spring. To a small 

 eye-lug at the top of 

 the upper sleeve a 

 string is attached 

 which extends down 

 to the hand of the 

 operator. 



The man stands on the U>p of 

 his ladder and lifts the jiole up so 

 that the bent tongues slip over the 

 bulb. If the bulb is too large, the 

 man pulls the string, thus moving 

 the top sleeve down so that the 

 tongues can spread out to fit the 

 bulb. By turning the pole around screw- 

 driver fashion, the bulb is taken out of 

 the socket. It is prevented from drop- 

 ping to the floor b\- the tendency

Above, a device for re- 

 newing the bulbs in high 

 theater and hotel canopies 

 consists of a long pole at 

 the end of which are 

 rubber-covered fingers to 

 grip the bulb securely 



At left, the end of the pole, 

 showing how the rubber- 

 covered fingers grip bulb. 

 The fingers can be spread 

 out or contracted to suit 

 the size of the bulb 



of the tongues to return to their 

 normal position and by the rubber 

 protectors, which grip the bulb firmly. 

 The pole is lowered, the old bulb 

 taken out, and the new 

 one inserted. 



If the operator does 

 not wish to move his 

 ladder for each bulb to be taken out, he 

 slides the middle sleeve down over the 

 first one. The top slee\-e and the 

 tongues can then be bent to either side.
