Clock 4 - Verge and Foliot

Clock 4 was designed with a Verge and Foliot escapement that was used before the pendulum was introduced to clockmakers. The time keeping with this mechanism is not as good as that of a pendulum because of the numerous variables within the mechanism, but adjustment by positioning the two weights on the Foliot arm can bring it within a reasonable accuracy. This is a visually interesting clock with its single hour  bar and weights, and the compound verge component made completely from wood is unusual. More details of the Verge and Foliot mechanism can be seen here.

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 1,2 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

For those clock builders who will be using CNC to cut the profiles the DXF files for this clock and Clocks 1,2 and 5 are available here for $36. This gets you all 4 clocks in DXF format, the files have been compiled to place the flat profiled parts for each  one sheet for each clock.

The files have all been re-created to remove as much as possible the broken lines in the originals.


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.
