SPEQIFICATION forming part of Letters Patent No. 523,530, dated July 24, 1894. Application iled October I9, 189S. Serial No. 488|664. (No model.)

To a'ZZ whom it may concern.-

Be 1t known that I, NELs JOHNSON, a citizen of the United States, residing at Chippewa Falls, in the county of Chippewa and State of Wisconsin, have invented certain new and useful Improvements in Sash-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appertains to make and use the same.

My Invention relates to improvements in s ash fasteners; and it has for its general ob- Ject to provide an exceedingly cheap and simple fastener adapted to engage and securely lock a sash without scratching, indenting or otherwlse marring the appearance of the same.

With the foregoing end in view, the invention W11l be fully understood from the follow- Ing descrlption and claim when taken in connectlon with the accompanying drawings, in which Figure l, is a view illustrating my improved fastener as connected to a window casing and adjusted to lock the lower sash in itsv closed posltion. Fig. 2, is a sectional view ofthe fastener, taken in the plane indicated by the line 2, 2, of Fig. 1. Fig.,3, is an end elevation of the fastener, and Fig. 4, comprises Views in elevation of the crank shaft and theV screw and washer for fixing the crank on the same.

Referring by letters and numerals to said drawings:-A, indicates a window casing which may be-of the ordinary construction.

B, indicates a sliding sash, and l, indicates thebody plate of myimproved fastener which is provided with apertures as l, for the passage of attaching screws through the medium of which it is connected to one of the side stiles of the window casing, as illustrated. This body plate 1, and the curvilinear wall 2, and cap plate 2, form a casing for the adjustable sash engaging shoe 3, which is provided with a circular aperture 3a, to receive the eccentric 4. The said eccentric 4, is

mounted on the angular portion 5, of a shaft 5, which is journaled in the body plate l, and cap plate 2a; and the said shaft is provided- 5o at its outer end with a squared portion 5", to

receive shoe adjusting crank 6, which is preferably secured in position by the screw 7, and the Washer 8, in the manner illustrated.4

The sash engaging shoe 3, is preferably of the configuration illustrated in Figs. l, and 2, so as to present a large surface to the side bar of the sash when it is moved into kengagement with the same, and it.is preferably provided with the broad ends 3b, so as to enable it to engage the upper cross bar of the sash when the same is in its closed position and the lower cross bar when `the sash is at its greatest elevation. Said shoe is designed and adapted to be adjusted through the medium of the crank or finger piece 6, and it will be readily perceived that when said crank or finger piece is moved in the direction of the arrow (see Fig. l), the shoe will be'moved into engagement with the sash and when it is moved in a direction opposite to that indicated the shoe will be drawn away from the sash. By reason of the large surface which the shoe presents to the side bar o f the sash when it engages the same, it is enabled to securely lock the sash against movement in either direction without scratching, indenting or otherwise lnarring the same, which is a desideratum.

My improved Sash fastener is also advandesire to be understood as confining myselfl to such construction and arrangement as such changes or modifications may be made in practice as fairly fall within the scope of the invention.

. Having described my invention, what I claim isv The combination with a window frameand a sliding sash arranged therein; of the sash fastener comprising a suitable casing, the

vsash engaging shoe arranged in said casing and having a broad end 3b, and the opening 3, a shaft journaled in the casing, and an ectoo centric or eocentrically mounted disk` fixed edge of said shoe to engage one of the side i o? tlllle shaft and arranged in the opening 3, bars of the sash, substantially as specified.

o t e shoe; the said fastener being connected yto one of the side Stiles of the window frame NELS JOHNSON' 5 and so arranged with respect to the sash as Witnesses:

to enable the broad end 3b, of the shoe 3, to J. W. WILLIAMS, engage one end of the sash and the outer LIZZIE DEUTSCH.
