David Fisher


The industrial revolution (and the series of events that led to this massive change in our culture) is arguably one of the biggest events in human history. The ability to mass produce items efficiently and quickly changed the global supply and demand dynamic, and the way in which we live our lives. While thinkers like Carl Marx saw it as having a negative impact on our perception of self, at a primary level at least the advances in design allowed people to work more safely, which can only be viewed as positive. David Fisher played a crucial role in the revolution, patenting two designs in the manufacturing sector that have changed the way in which people work and live.

Fish’s first patent was for a joiners clamp. Anybody who has ever been in a woodwork or shop class will be familiar with the concept. The problem was that furniture builders were wasting an incredible amount of time while waiting for glue to dry where they had joined wood. You could try and position the wood so that its own weight compressed the pieces together, but there was plenty of waiting involved and you could never be certain that the join would stay strong. A clamp allows you to force two pieces together firmly, ensuring a solid join, and freeing you up to work on the rest of the piece. The simple screw design improved productivity exponentially.

 

 

Fisher’s second patent was a device known as a furniture caster. During the 1800’s a lot of the manufacturing process was reliant on brute human strength, but moving heavy objects was dangerous to workers and the furniture alike. Fisher saw a gap, and created a system of hooks and pulleys that distributed weight in such a way that pieces could easily and safely be moved by one person. Again, this is a profound contribution that is still used to this day in a variety of different fields.

Well done to you Mr Fisher!
