Every sash window is actuated by four cords, two for the upper frame and two for the lower. When one snaps, the frame can still be operated properly, though with some slight difficulty; but when a pair of cords give way, the window is a source of danger and should receive attention. Should you not know where to find these cords, pull both sections of the window down as far as they will go, and you will see the four cords, two on either side of the frame and near the top. If more than one is broken, they will have disappeared from sight.
When a cord of the lower sash needs replenishing, act as follows: Remove the beading around the window on the side where the cord has snapped, lift the sash an inch or two to clear the bottom horizontal beading, then swing it round against the wall, using the good cord as a hinge. Now examine the fixed frame of the window, along the edge where the sash travelled up and down. Here will be found a trap-door which can be opened by prising with a screwdriver. Open it, and feel inside for the heavy sash weight. Bring this into the open and it will be seen that a cord is threaded through an eye in the head; note how it is knotted at the end in order that the new cord may be fixed in the same way. Now pull out the cord, and turn to the sash which has been swung back out of the way. On its edge is fixed another piece of old cord; mark on the wood with a pencil where each nail is driven in, and make an additional mark where the bottom end of the cord reaches. Having carefully noted these points pull away the cord, and measure off from the hank of new material a length equal to the combined lengths of the old pieces taken off the sash and out of the eye of the weight. Allow two inches extra for the knot.
At this point turn to the little pulley at the top of the window frame. Take a long length of fine string and attach a small heavy weight to it — anything handy will do so long as it can be passed over the pulley wheel-— then push this weighted string over the pulley and into the dark chamber. Soon the weighted end will be seen through thr trap door; catch it and be careful not to let either end of the string go. Now fix the sap’ cord to the heavy weight and plac the latter in the dark cavitr Tie the free end of the cord to tJL string, and by pulling on the oute; end you are able to draw the sash cord up the chamber, over the pulley wheel and out into the open. Take hold of the free end of the sash cord, and pull it so that the weight rises to the top of the box, drive a nail temporarily through the cord, and into the wood close to the pulley. Next, turn the sash frame round, so that the cord can meet it. Nail the cord to the frame in the exact places indicated by the pencil marks, and see that the end is just where it was in the original piece. Remove the temporary nail, butatthe same time grip the sash, so that the weight when released does not fall with a jerk. Fit the sash in its grooves, replace the side beading of the window, and the job is finished.
When one of the cords of the upper sash needs replacing, unship the bottom sash as before, remove the beading which runs between the two sashes, and look for the weight in a rear compartment of the dark chamber. Beyond this, the repairing follows the same lines as before.
Be careful to use proper sash cord for the work; if ordinary cord is used, it will stretch in time and become too long to act as it should. SOLDERING.
