.....Lyons Bakery - Harvest Pie......


(1) By David Lawrence

The Harvest Pie was one of the last major new products to be manufactured at Cadby Hall. It was also produced at Glasgow. It started life with the name Homemade Pie but there were objections to this name as it implied that it was home made. It was an innovative process since it was made without the incorporation of dough trimmings. The team of people involved was large. As many as I can now remember are listed below. I'm sure there are others that I have forgotten and hopefully we'll add these as we go along.

I was lucky enough to be on the team as Process Engineer under Roy Ingledew and become joint patent holder,with Roy, of the process to produce the pie without trimmings. This involved blocking out the divided piece of dough to become a base and another to become the lid, instead of the usual method of sheeting the pastry, and thereby having to remove trimmings. The lid then had to be placed on the fruit filled pie base and released at the right moment and not fall off prematurely. The design of this 50 feet long make-up machine was still being finalized after the oven and other equipment had completed installation in 'Y' block.

The plant was being manufactured by Baker Perkins at their Peterborough factory and consternation reigned when they informed Lyons that they could not guarrentee that the lidding process would work. Apparently no one had told the Lyons upper management that the process had not been fully prooven yet.

In what could have become my final task at Lyons I rather rashly offered to build a demonstration rig to prove that our proposal would work if they'd give me £5,000 to spend and three weeks to do it in. They agreed and I didn't get much sleep during those three weeks and woke up one morning with drawing instruments on the blanket. Thanks to some fine cooporation from Tommy Edwards and his Cadby Hall Machine Shop staff my rapidy built rig was set up in 2nd, floor C block and given a couple of intensive day-long trials. These were sufficiently successful to enabled Baker Parkins to reverse their cautionary stance and manufacture of the make-up machines got under way. Although this may sound dramatic all the team were working tirelessly to get the project into production. The opposite was unthinkable.

I also had the task of commisioning the three make-up machines at Cadby Hall and the two at Glasgow.

As you may see on the drawing in the Patent Spec. below there are eight plattens on the sub circuit taking the lid round to the pie base below. This had originally been designed with four plattens but on test start-up it was found that the acceleration loads were too great and the intermittent gear box driving the sub-circuit failed. By adding four more plattens the loads were reduced because the index length and speed was less.

There were a number of problems before the launch. Bakery Director D.C. McKenzie called a group of us in to attend a day long meeting on Boxing Day 1967 - the day after Christmas Day - an unheard of thing and every problem area was discussed and analysed .

The following were members of the Harvest Pie project team. Please help me with other names.
