IMPROVED SASH-SUPPORTER.

To ALL WHo'M Ir MAY ooNoERN:

Be it known that I, JOSEPH AYERS, of Greenbush, in the county of Rensselaer, and yState of New York,

have invented a new and improved Sash Supporter; and I'do hereby declare the following to be a full, clear, A

and exact description of the same, suflicient .to enable one skilled in the art to which the invention appertains to make use of it, reference being had to the acwmpanying` drawings, which are made a part of this specifica-- tion, and in which- Figure l is an elevation.

Figure 2 is a view of the edge of the sash, showing the at side of the spring.

Figure 3 is an elevation, showing the spring-holder without a roller.

This consists of a spring attached to and embedded in the vertical edge of the sash, the free end being arranged to spring outward and occupy indentations ,in the window easing to maintain the sash at given heights, except under the application of' manual pressure, which overcomes the outward force of the spring.

In the drawings, A is the window casing, B the upper sash, and C the lower sash. In indentations or recesses in the outer edge of the vertical stile are attached the springs D, which, in figs. l and 2, are shown with rollers, E, but in fig. 3 a. curl of a volute shape on the end of the spring is made to do duty as the roller in the other figures. In the face of the window casing, fitting aga-inst the edges of the sashes, are rounded recesses, F, into which the rollers E protrude, when bythe raising of the sash the rollers are brought opposite to the said recesses. The force of the spring is sucient to maintain the rollers in the recesses which they may be occupying, unless the force oi" the hand is added to the weight of the sash. As the weight of the sashl is constantly directed downward, the recesses F are made more abrupt at the lower side than the upper, so that the springs may be so readily retracted; the inclination of the upper portion of the recess is so gradual that it more easily overcomes the resistance of the spring when the sash is being raised. The rollers, as shown in figs. l and 2, are probably preferable, but the curl-spring (tig. 3) may answer a good purpose, with somewhat greater friction.

Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

The spring attached to the edge ofthe sash and engaging in recesses in the casing, substantially as described and represented.

JOSEPH AYERS,
