977. Hatchet attachment for a hammer, the claws of the hammer fit through the pegs:

From Jim Brown's collection.

978. K-D valve spring remover, used to remove engine valve springs without removing the cylinder head. The valves are held up by pressurizing the cylinder with air. Very useful for replacing valve seals on OHV engines.

979. Boxmaker's hammer, the pointed end is used to pull staples and pry lids off. The only similar hammers that I could find on the web were German latthammers, which are used by carpenters.

It's also classified as a strapped hammer, since it has metal straps that extend over part of the handle for reinforcement.

980. "Machine for inserting and clinching staples", patent number 274941.

981. I didn't know that there was a need for such a product, but apparently when milking cows, serious eye injury can occur from the switching of the cow tail. The device below is a cow tail holder, when in use the larger end clamps to the leg and the other end attaches to the tail.

It was patented in 1891, number 444,428, over 100 other patents for a wide range of contraptions that perform the same task can be found on Google patents.

According to this site, the inventor of a cow tail holder estimated that between 15,000 and 20,000 milkmaids or milkmen received severe eye injuries each year.

More information on the hazards of dairy farming can be seen here.

982. Boot knife, kept in a sheath that is clipped to the boot.


I just received the realized prices from the auction that I attended a while ago, in 1998 the Falconer plough plane sold for $23,500, five weeks ago final bid was $31,900.
