From Wickypedia:

Bell gauge: A bell-shaped metal gauge enabled knitters to measure the diameter of knitting needles. Different types of yarn need different sizes of needle and this gadget allowed knitters to make sure the needles were suitable. Patented in 1874, the Chamber’s Bell gauge was recommended in The Lady’s Knitting Book published in 1875.
The steel knitting pins prevalent in the 19th century were made of wire. As a result, the standard sizes of British needles were the same as those used to measure the thickness of strands of wire. It was not until the 1970s that knitting needles were measured according to the metric system.

The pattern includes a picture of the pelegrin and a picture of the Bell gauge.
