W. NiPPERTl SCREEN 0R STORM WlND-OW FASTENER. APPLICATION man MAY 29, :919.

into place from the outside, and finally the buttons 13 are applied to the screws l() and turned thereon until they contact withV the sash S. If the latter be accurately tted to the window as seen in Fig. l, such contact of the inner face 17 of the button` with the outer edge of the sash will occur at a time when said face also contacts with the outer face 8 of the ear'; but if the sash be somewhat thicker as seen in Fig. 2, the but ton will contact with the sash before it touches the ear. In any event the necessity for having the button appreciably larger than the ear is now apparent, because although the sash can be put up between or taken down from between the fasteners when the buttons are not on their screws, the buttons when applied should be amply large to project well over onto the sash frame S. Therefore, it is preferred that the screw project from the ear in a plane beyond that which the plate l would occupy if projected, and also that the button be larger than the ear for the reasons dcscribed. Also the button should have flat faces so that when screwed home it will not injure the woodwork.

If it be the custom of the householderto put up a storm sash' during cold weather, in the spring he can remove the sash and the fasteners. Or it may be that he will remove the sash and replace it with a screen, and in that case the same fasteners may be employed to hold the screen frame. Or, it may be that he puts up a screen in warm weather and has no storm sash, and in that event the screen and the fasteners will be removed in the fall and replaced in the spring. It is not necessary that any particular set of fasteners be applied to a particulel' Window or to a particular sash, but in, order to ada-pt the fasteners to cas-ings of various thicknesses it may be well to nr he them in sizes wherein the distance betr-J the spur 3 and the inner face 7 of the ear will differ, being a shade over an inch for a casing one inch thick, a shade over an inch and a quarter for a casing one and quarter inches thick, and so on.

Having thus described the invention, will-rat is claimed as new is:

l. A screen fastener comprising ay plate bent into substantially U shape, a screw pro-- jecting rigidly from one arm of the j erpendicular to its threaded on the screw and of a size tc er:n tend across the projected plane of the body of the U.

2. A screen fastener comprising a piate bent into substantially shape, a screw projecting rigidly from one arm ,of the L? and fully oi'set out of the projected plane of the body of such U, and a button threaded on the screw and milled on its edge.,

3. A screen fastener comprising a plate provided at one end with a driving spur, and bent at its other end into a thin, square ear having flat faces at right angles' to the plane of the plate; a screw projecting idly from the center of and perpcndicui to said ear and wholly offset out o'l projected plane of said plate; and a br threaded on the screw, its body bein preciably larger than said ear and its fiat, all for useas described.
