Here is a note on the Hemingray-110 pictured on page 29 of the August 1969 issue.

The Hemingray-110 is a dead end spool and is used in a dead end clevis or shackle. The steel pin that is dropped down through shackle and spool has a thin lead sleeve around it to cushion the pin against spool and help fill out the slack as the hole in the spool is some larger than the steel pin. I assume these are a follow up of the Hemingray-109 as they serve the same purpose and fit the same shackle. The top two grooves in the Hemingray-110 were used for wire up to and including #9 copper, but we had them on Ckts. of #6 copper, then you had to use the bottom groove so the wire had a groove of more width to fit in and pull against. The bottom groove is wide enough so you could use it for wire that was one or two sizes larger than #6.

The shackle used for the Hemingray-109 and Hemingray-110 is a very common shackle and of course now days uses a porcelain spool.

Editor's Note: I myself have noticed a few of these Hemingray-110's showing up in collections.
