    Found in my late fathers shed. He was a carpenter by trade but had links to the manufacture of bricks. This a steel or cast iron hand operated device which appears to be able to jack up or support something due to the central slide which extends or retracts when the handle is turned. On the base there is a set of spikes which I assume clamp a section of wood to the item. This is then held firmly in place by the notched handle which clamps down onto the wood. The item is 260mm long when closed and approx 350mm when extended. I would love to know what it is.

      A jack mechanism to put on the wood beam of your choice for any length .

      My thinking is that it's a building jack. Secure it to a beam in your building that that is sagging so you can add support.

      I didn't find one exactly like it but a couple were close when I googled vintage house jack.

      Specifically designed for jacking up (or rather in) tongue and groove floorboards.
      The clamp sat on the main beam with the toothed eccentric keeping it in position. The screw jack would then apply pressure to the floorboard 'mating' it firmly with the one in front. The boards would then be nailed (concealed) in position and the process repeated. Here in South Africa they are sometimes called 'wagon jacks' - used for securing the floor planks on the bed of an ox wagon.
