A single page from the weekly 'Engineering' (June 29, 1900) summarizing a British patent abstract for textile machinery. It describes a slide or flap, operated by hand or automatically by a spring-loaded rod, that closes the gaps between door ends in front of a self-acting mule carriage to keep dust out. Two line drawings show the door slide mechanism; the following patent entry, No. 10,099 by T. Wilde of Oldham on self-acting mules, begins at the foot of the page.
