ing vthe contacts.;
a similar view of the supporting plate carry- -piece of similar material. These jcontacts are very unsatisfactoiy for. the reason that the slightest accumulation offdustand dirt between the two pieces of metal interrupts the 'current and makes an incom lete circuit. Another objection is that the at pieces of metal soon lose their resilience and become useless, particularly if they are exposed to changing atmos heric conditions.
Referring to tlie various parts byl numerals, 1 designatesa base plate having the upstanding annularflange 2 and an inward extending annular flange 8. Fitting within ,the upstanding flange and resting on the flange 3 is a supporting plate 4 of hard fiber or other insulating material. The flange 3 'is provided with alug 5 which enters an opening in the plate 4 to prevent the rotation of the plate, as is common in this'class of device.
Secured to `the plate'4 are two contacts 6 leach of which consists -of -a screw having a head and a shank 8 which is threaded through the plate.: The screws are laced a suitable distance apart and their heat s cons/titute thecontact points. On the Shanks S are secured binding nuts 9 which not only serve to secure the circuit Wires in place, but als4 serve to securely hold thescrews to thej ApplicatiodledvNovemberg, :1907.
