IMPROVED WINDOW-SASH SUPPORTER.

Specification forming part of Letters Patent No. 46,472, dated February 21, 1865.

To all rwhom it may concern Beit known that I, HENRY F. JENKs, of

Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Window-Sash Supporters 5 and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a iull, clear, and eXact description thereof.

Figure l is a sectional view of the sash-supporter patented to Geo. F. Foster, April l1, 1848, and upon which the invention herein described is an improvement. Fig. 2 is a view in perspective of my improved sash supporter. Fig. 3 is a vertical section in a plane through tfie window-sash and the window-frame.

My invention relates to that variety of supporters for window sashes by means of which the sash can be held at any desired point in the wiinlow-frame,instead ofat certain iixed points only; and it consists in certain improvements upon the supporter for this purpose patented t i Geo. F. Foster, April ll, 1848.

In order that these improvements may be understood, it will be necessary to refer to the construction ot the Foster supporter. (Shown in Fig. 1.) It consists ofa spring, A, and a tngenpiece, B, detached from each other, except when combined together and adjusted in the windowsash. Upon the back ot' the spring` A is placed a hook-shaped piece, a, against which the short arm b ot' the fingerpiece bears, for the purpose of operating the spring,l which, except when withdrawn by raising the iinger-piece lever, constantly presses against the window-frame with its curved face c, and by friction enables the sash to be sustained at any height.

It will be observed that the spring is secured directly to the window-sash at d, having no frame to which it is attached, and the iinger-piece has its fulcrum upon a pin which passes through the stile. From these two facts have arisen the principal objections to this supporter, which in other respects is considered the most desirable of its kind in use. In the ,first place, the method of attaching the spring to the sash is objectionable on account of the liability of the threads of the screw to tear out the soft wood into which they enter from the effect ot' the tension of the spring, and also because this mode of attachment provides no practicable means of varying the tension of the spring so as to adjust it to window-sashes of dii'erent weights, it being very desirable that the spring should not be stii'er than is necessary to support the sash. In the second place, it requires the services of a skilled workman and the expenditure of much time to apply one of these supporters to a windowsash, for the reason that there are no means for determining the place in the sash at which the hole for the fulcrum-pin of the iingerpiece shall be made, except by the most careful measurement. I propose to remedy these objections to the supporter above described by so arranging the spring and tin gerpiece that they can be attached to a frame and the whole be Without difficulty fitted by any ordinary workman to the sash.

1n the accompanying drawings, C, Fig. 2,

- is a rectangular frame, whichis let into the stile of the sash and held by screws e e', as shown in Fig. 3, a mortise. being cut back of the same of sufficient depth to allow ot' the working of the spring D, which is attached to the frame at f. The tension ofthe spring can be easily varied by slackening the screw f, so as to accommodate window-sashes'of different weights.

E is the finger-piece, which operates the spring D, as shown in section at Fig. 3, and instead of having its fulcrum upon a pin which passes the stile of the sash, it has its fulcrnm atg on a pin through the frame C. In all other respects the apparatus is the same as that patented to the said Foster and above described.

Vhat I claim as my invention, and desire to 4secure by Letters Patent, is-

HENRY F. JENKS.
