ond through each plug is e central aperture through which passes the springpressed plungenf), having a head 9, -and a spring 9b. These guides are rectangular shapey in cross section with one side open and the outside face is slotted as et l0, so that the screen may be inserted by passing it through the slot/10 and raising it above the top of the guide until the lower end drops in the guide when itis then pulled downto its position of rest. The screens are provided with s screen frame 11 at the margins and the bottom of the screen frame 1l of the screen D,

rests upon the periphery of the Contact strip i roll 5, while the top of the strip, 11 of the lowerscreen E is pressed against the com tact strip 4. The periphery of the contact strip 5 where the screen wipes it is the shape oia segment ofc circle in cross section and the radii thereof are of such calculated length that the sash. in revolving brings the Contact strip always in contact with the stationary .screen D. The upper screen is held yieldingly against the contact strip 5 by gravity. The contact strip 4 is of o ditlerent shape (as shown in. the drawings), its shape not beings() material, providing its contour curately against the lower screendfrarnes of' the upper screen D and the roll l depresses the screen E in its guides, and slides across its upper frame bar.
