Figure lis a seetional elevation of my'improved shade-cord retainer,` and Figure 2, a sectional plan.
General Description.
A represents a plate, to be secured by screws or otherwise to a window-frame, and this plate hasa projection, e, which serves as a guide for the rack B, the upper end of the latter being provided with'a pin, d, on which turns the cord-pulley b.
In projections c c,on the plate A, turn the journals ci' a cylinder, C, a rib or thread, t, being arranged spirally on the cylinder, like that ot' an ordinary screwthread, and the teeth of' the rack 'B being inclined to suit the thread. i
The rack B is elevated or lowered by turning the cylinder G in one direction or the other, to tighten 0r loosen the cord, which passes round the pulley b, the cylinder serving to lock to the rack and retain thecolrd aft-er adjustment.
It will be understood that the upperend of the rack may he simply hooked for receiving the cord, insteadv of having a pulley, as shown and as described above.
