TO ALL WH-OM IT MAY CONCER:

Be it known that I, ORVILLE M. RIDGWAY, of La Porte, in the county of La Porte, and State of Indiana, have invented e new and improved Window-Sesh Fastener; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use thesemc, reference being had to vthe accompanying drawing, forming part of.' this spec-iiicetion.

The ligure is an inside View of' a. window, part of the casing being broken nwey to show the construction.

My invention consists in the coinbination of e. metallic spring and rubber block with the opposite edges of the window sash, for the purpose oi' holding i'r. securely at any point to which it may be raised.

A is the windenr casing, about the construction of which there is nothing new. B is thc window sash, which is made and secured in thc casing A. in the ordinary manner. C is a. metallic spring, which is let into at cavity or groove formed-in the side edge of the sash B. One end of the spring@ is secured to the sash by screws, in such ai position that the other end may press against the bottom of the groove in the casing in which the szrsh moves up and down. The free end of the spring C should bel curved or bent so as notJ to weer the casing by moving the sash up and down. D is e rubber block, which is let iut-o a uiortise formed in the side edge of the sash directly epposite to the spring C, :ts shown in the drawing. The effect is that the spring C presses the 'sash to one side so that the rubber block D may be pressed against the side ofthe casing und hold the sash in any position in which it muy be placed. In-ruisiug und lowering the sash it should be pressed towards the metallic spring, compressing it, :und freeing the rubber from the casing which allows the sash to lic easily raised and lowered, When released the metallic spring forces the sash beck, pressing the rubber block against the casing and holding the sash securely. The spring C and rubber block D may be placed neuzthe upper edge of the sash, or near its lower edge, es may be desired or convenient; but I prefer to place them neer the lowei` edge, as being a. little more convenient in raising or lowering the sash.

I Gleim as new, end desire to secure by Letters Petent- The combination/of the metallic spring C, rubber .block D, when `construct-ed and arranged upon cach of the seshcs B, es herein set forth for the purpose specified.

v ORVILLE M. RIDGWAY.
