from the trough 18 in this regard it is believed that the trough 18 should be of a width of approximately 1 to 5 cms it should be understood that a wider trough 18 has greater water carrying capacity but also provides a larger area to trap debris 22 and is less effective at drying debris 22 trapped therein the water collection capacity of the present invention may be further enhanced by providing an arcuate lip 24 at the lower end of the shield 14 this lip 24 serves to further direct the water downward into the screen 16 and to provide a further arc which assists in the separation of the debris 22 from the water as is shown in fig2 and 3 the apparatus 10 may be fastened to the gutter 11 by attaching one or more lanyards 26 to conventional studs 28 used to anchor the gutter 11 in place in the preferred embodiment shown in fig2 the lanyard 26 is attached to the stud 28 by a hook 30 which engages the stud 28 the lanyard 26 then is passed up through an opening 32 in the shield 14 the lanyard 26 may then be held in place through any conventional means including a spring clip 34 or a lock ring not shown in this manner the lanyard 26 may be pulled up tight and then held in place to provide a snug fit between the apparatus 10 and the gutter 11 another embodiment of the fastening means is shown in fig1 the lanyard 26a in.
