Clock 3 - Verge and Foliot

Clock 3 was designed to be a replica of a typical 15th century Verge and Foliot clock, but it never got finished and was replaced with the more ornate design for Clock 4. I have resurrected it here with some small refinements as in some ways it is a much simpler design than the others on the site. This clock using the verge and Foliot was never very accurate, hence the use of only the hour hand, it wasn’t until the introduction of the pendulum that accuracy was improved, in fact many original clocks were modified with a pendulum to improve the accuracy, so very few examples remain.

This Clock has been designed in inch's so all the shaft’s work out correctly for all those working in imperial measures. Gears never work out in round numbers though, no matter what unit of measure you use.  

Drawings for this clock in PDF format can be downloaded here, they are drawn to scale so that they can be printed at full size on either A3 or Super B papers. I realise that not everyone has access to these large format printers so there is a way of printing out smaller area’s at full size  standard paper sizes using Acrobat Reader. The procedure for doing this is shown below.

These files are free as are the ones for clocks 2,4 and 5 but for all newer clocks there is a small charge.

A sample from the DXF/DWG files is shown when you Roll Over the arrow .The actual files purchased above are included on one large sheet so that they may be directly loaded into your CAM program

To print only a single item of the drawing to scale using Adobe Acrobat Reader,  do the following

Go to  Edit  then click on   Take a snapshot

Move the cursor to the top left of the item you want to print and hold down the left mouse button whilst you drag a box around the item.  The inside of the box turns blue and you can now go to  File and then click on  Print  . This brings up the print dialogue, make sure Selected graphic  is selected and that the Page scaling is set to  None  and the click on  OK,  .As long as your printer is connected you will have printed the item at size.Do this for each item you want to cut out.
