Pic15. What the?
This is a comparative Brinel hardness tester. A square bar of
calibrated known harness is inserted in the square hole between
the ball and the punch body. The ball is positioned on the component
to be hardness tested and the tool is struck with a hammer the
square test bar is removed and the hemispherical mark left on
the test bar and the component are measured for diameter and the
values are cross matched on a table to give the HBN number. These
tools are still very common.
Thanks to Michael Slattery and Ian Speer for identifying this
one. |

Pic 13.
The item is a “Ring Cutter” Generally used in hospital
emergency departments for safe removal of rings. Especially when
there is swelling due to trauma. Hook piece slips between ring
and finger, light pressure applied by thumb on plate. Rotate wheel
until ring cut. Metal blade cannot cut finger. (Trevor Jones) |

Pic 11 - Another whatsit - marked BONUM 2001. The pointed end
looks like a short piece of star picket.
Feedback #1: The Bonum 2001 is a general purpose scraper, the
blade (star picket) should be located centrally in the head of
the handle. It should be sharpened on a grinding wheel with final
finishing on a flat stone to give a micro bevel. It works a treat
with three cutting surfaces to be dulled before resharpening.
I obtained mine from the deceased estate of a timber boat builder.(Gordon

Pic 9- Cast iron Ox-bow pin.
"Feedback - this is an Ox-bow pin in the open position.
It was used on the old wooden ox-bows to retain the 'U' shaped
bow in the yoke - Tom Partington USA." (see also below two
pics) |

Pic 7 - Some sort of gauge, from the electrical
/ electronics industry, going by the name EMF. See also below.
The item pictured on your whatsits page is a welders Fillet gauge.
It is a unit still in use today to measure the fillet size of
what you would call a Tee weld. Fillet weld size determines cost
pricing on welded work of large proportions as well as distortion
control.
The would have been imperial dimension units but later models
would of course been in metric. The EMF brand was a British company
manufacturing welders and electrodes and ancillary equipment.

electronics industry, going by the name EMF. See also above.
Answer:
Not many guesses recieved, but I will put this one to rest.
EMF made welding rods (among other things). I was told, and it looks
right, that these gauges would be used to measue a weld fillet in
a 90Deg join. (Thanks Gerald Brookes) |

Pic 5 "Jacksons Patent, for nos 2 & 3 buttons"
Answer: No responses on this one - This is a wrench
/ key for adjusting the joining buttons on leather and other belting
for belt driven machinery. Jacksons supplied this belting also.

Interesting Gadget - Pic 3- but what exactly is
it? Feedback from Graham Clegg, Powerhouse Museum, Sydney,
Australia:
The item is a tool used to fit wire hook type belt fasteners
to flat transmission belting. The hooks come on a paper card --in
use the hooks fit into the brass divisions and are secured there
by the loose pin. The belting is placed between the sharp pointed
ends of the hooks and the hooks are squeezed shut in the jaws
of a vyce, embedding the fastener hooks in the belt." |
