A thickness of fiber is laid on inside ofsteel angle to secure absolute insulation. The bolts areinsulated by use of brass thimbles with a fiber Weber Insulated Joints are in use on Americanroads than any other kind. In using the track electric circuit in order to insurecarrying the current from one rail to another, it is nec-essary to connect same by wires. To protect these theyshould be placed behind the angle bars, and trackmen. MISCELLANEOUS. 315 should carefully handle such joints so as not to breakthese connections. If it is necessary to do any work bywhich these will be disturbed so as to break the con-nections, the proper authorities should be notified atonce. After the plant has been put in place a considerableportion of the working of same falls on the running parts should be carefully cleaned and oileddaily. The bolts at heels of moving points should beso adjusted that an additional strain will not be broughton the levers in the tower. A very good method ofaccomplishing this is to use an angle bar, which isslightly bent, at the heels of movable point frogs and
