with their openings in substantial aligrmient.

Extending from the upper ends 23 of the arm; Y-- portions is the anchoring means E. This may;

comprise a portion of the length of wirereferred to, forming a pair of substantiallystraig'htpro jections 25 from the arm portions.

erably'four throws 32 arevfprovided for thebell crank portion 3|, with a clip'receivingsection 33 to each throw. From Figs.

Pivotallycarried by. each throw 32 at the clip receiving section 33 thereof is a suitable clip on connector v 34, which. may be formed offspringy' wire and incl'udefla' pair of ;arms 35, diverging from a pullflchain receiving eye36 withthe'w'ire notquite itouching as at 31,,informingtheeye.

The free .ends of the .arms are formed. into a,

Then the second length 5| of the tape may be --wrapped?about"the finger tip, overlapping the ends of th e 1engtl 5|l, as shown in Fig. 1. Since adhesive tape is widely used and is inexpensivef'after the cast is'removed the lengths 5|! and 5l of tape may be discarded.
