Letters Patent No. 111,847, dated February 14, 1871.

IMPROVEMENT 1N sAsH-conn FAsT'sNERs.

The Schedule referred to in these Letters Patent and making lpart of the lame.

To all whom 'it may concern: 'I

'Be it known that I, WILLIAM N. JACKSON, of Muncie, Delaware county and State of.' Indiana, have invented a new and improved Device of' Attaching Weight or Balance-Cords to \Vindow-Sash; and I do Vhereby declare that the following is a full and exact description thereof. l This invention relates-to that class of devices which 1s used for attaching weights or balance-cords to window sash and It consists in the construction and arrangement of sifich devices as will he more fully explained hereina ter. i

Figure 1 is a sideV elevation of a portion of a window-sash, having my device secured or placed therein. Figure 2 is a side elevation of a section having an end View of my improved device, and showing the cord and the manner of securing it to the device.

Figure 3 is a perspective view voi' the device, showing the construction thereof. A

' Corresponding letters refer to corresponding parts in the diiferent figures.

rlhe cord-fastener is shown at G in fig. 1, and consists of a piece of metal, the outer surface of which 'is in the form of a segrnent of a circle, the circle being -so far extended as to constitute something more than a, half circle, in order that, when it is driven into the holevwhich is bored into the sash, it shall be held rmly'in its position. .t may, however, be only onehalf of acircle, oreven less, and answer a very good purpose.

The interior surface e e is concave in form, but the circle should be such as to leave the metal in the center thereof ot' greater thickness than it is at itsedges, in order that additional strength may be imparted to it at that point.

In the outer end of this fastener G a slot, 0, is formed, as shown in iig. '3, it being for the reception of the cord d.

The concave portion e e upon the interior of the casting does not extend throughout its entire length,

there being flanges a .a eizterlding'y downward from its end, in order that when the cord is inserted the knot i upon-its end shall pass behind such flanges and thus receive it in its position.

The manner of applying this device is as follows:

rDhe fastener C, having been constructed substantially as described, a hole is bored in the sash, as shown in lig. 1, and the fastener is driven therein, the hole or aperture being of such diameter as to serve it to t snugly therein. It willbe seen that the position in which the fastener is placed with reference to the sash is such that, when the cord is inserted into the slot in' its outer end, any weight which may be attached to the opposite end of such cord will tend to' draw the fastenelinto its aperture, and thus hold it firmly in its position and prevent its being loosened bynse. In applying it tothe sash a groove is formed in the sash from the point where itis secured thereto for the cord to rest in, as shown in Iig. 2, and a recess is also formed below the fastener for the reception of the knot upon tlre'end of the cord;

Some of the advantages due to this form of fastener.

may be enumerated as follows:

Its arrangement with reference to the sash insures its remaining in position and without becoming loosened longer than those now -in use; and, lastly, its position with reference to the4 sash prevents any water which may e'nter it to immediately drain out, and thus prevent the `rotting of the sash.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

The cora-fastener, slotted and conoaved as shown, when combined as described with an inclined circular' opening in the sash, all as and for the purpose set `forth.

W. N. JACKSON.
