'IO ALL WHOINI II MAY CONCERN:

De it known that I, SANDY HARRIS, of Philadelphia, inthe county of Philadelphia, in the State of Pennsylvania, have invented a new andimproved Spiral Sash-Weight; and I do hereby declare that the following is a full and exact deseription-thereoi`, reference being had to the accompaning drawings and to the lettersl of reference marked thereon. p

'Ihe sash-weight in common use has an eye or hole for the cord at the upper end, and as this eye is out of practical reach when the weight is in its box, itis necessary' to make the cord fast before putting the weight in. It is also necessary, for the same reason, to do this before attaching `the cord to the sash. It being obvious that if the cord could be brought down to the bottom of the weight to be attached, this thing could be done as well after as before making it fast to the sash, and thereby a great saving in time and labor effected, has caused me to make the invention which I will now proceed to explain.

I take a weight ofthe usual form, except the neck and eye, Figure I, on the drawing, say an inch by an inch vand a half and eight inches long. From one end to the other I sink a groove, A, Figure II, Wide enough to take in the cord and deep enough to allowl it to hang through the centre of the weight. To prevent this groove from destroying the balance of the weight or allowing the weight to fall from-the cori I give it a spiral direction, using, however, abrupt orangular turns instead of the. regular curve. Beginning at the centre ofthe edge at one end, B, Fig. II, I extend the groove a half inch. I then take-it directly across the corner C, Fig. II, to the middle of the side D, Fig. II, along which I extend it three inches. I now cross the next corner as before, F, Fig. II, to the middle of the second edge E, Fig. I. From this point I extend it one inch, and then cross to the middle of the-second side, G, Fig. I, where I extend it threeinches. I now cross to the middle of the rst edge again, and with a half-an inch there complete the groove. Making it in this way, it will be seen, leaves the'same length of groove on one edge that there is on the other, and the same on one side that there is on the other, so that the balance of the Weight is preserved, and its liability to fall from the cord prevented.

Where an even balance in the Weight is not essential, the whole groove, except the tw end angles, can be sunk in one side. Inthis case the beginning and ending halt` vinches will fall on different edges. They might still fall both on one edge, but that would be an unnecessary interruption ofthe balance.

With a Weight made in this way the cord can be made fast to the sash at convenience, the sash put in its place, and the cord over the rollers. The business of runningup the sash, tying a knot at the lower end ofthe cord, and putting on the weight, would be scarcely an item in either time or labor.

This Weight, especially where but one side is grooved, can be easily cast, and of iron or other suitable material.

What I claim as my invention, and desire to secure by Letters Patent, is the mode or modes, substantially as herein described, of attaching the sash-cord to the weight.
