FRANK I1. ROSENTRETER, OF ROCHESTER, NEW YORK.

SASH-CORD FASTENER.

SPECIFICATION forming part of Letters Patent No. 559,953, dated May 12, 1896.

Application filed November 2, 1892. Serial No. 450,793. (No model.)

To all whom it may concern:

Be it known that I, FRANK L. RosnN- TRETER, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Sash- Cord Fasteners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

My improvement relates to gravity sashbalances, or those in which the sash is balanced by a weight running in a. boxing of the window-case.

It also relates to that class in which a metal band or ribbon is used in place of the cord ordinarily employed.

The invention consists in the special construction of the fastening for securing the band to the sash, as hereinafter described and claimed.

In the drawings, Figure 1 is a sectional elevation of a portion of a window casing and sash with my improvement attached. Fig. 2 is a perspective view of the attachment for the sash. Fig. 3 is a longitudinal vertical section of the same.

A indicates the window-casing, and B the sash.

O is the flat metallic band or ribbon, D the fastening that attaches to the sash, and E is the weight and G the pulley over which the band passes. The sash-fastening D is of special form, and is designed to fit endwise in a round hole bored in the edge of the sash by a common bit or anger. Therefore it is of approximately cylindrical sha-pe, as shown in Fig. 2. The upper rear portion, however, is cut out in a series of steps, and it is provided with two cross-bars a b, one in the rear of the other,with a space between and located at different levels, the front one being the higher. The interior of the block below the cross-bars is hollow and in front it has two projecting lips c c, forming offsets, with a space between them sufficient to receive the width of the band. At the opposite end and on the under side is a downwardly-projecting lug f. To

attach the band, the end is inserted under the front cross-bar. It is brought up and around the rear cross-bar b, is then passed under the front cross-bar a, and then, together with the main length of the band, is turned up at right angles to the block, and rests within the space between the two projecting lips c c. This makes a loop around the rear cross-bar and leaves the two thicknesses of the band in contact around the front cross-bar. The strain on the main length of the band makes the contact closer, and as there are no sharp bends there is no undue danger of breakage. The band by being inclosed between the lips c c is shielded and held from contact with the easing as the band runs up and down and the parts are held perfectly centered.

The device above described being of cylindrical form is adapted to be fitted in a round hole bored in the edge of the sash, while the steps in the rear give space for the attachment of the band, and the cross-bars serve as a secure attachment for the band.

The strain of the band on the outer end of the device causes the inner end to be tilted downward and the lug f to clamp into the wood, thereby holding the device firmly in place.

Having described my invention, I do not claim simply and broadly a clip provided with cross-bars to which the band is attached.

\Vha-t I claim as new, and desire to secure by Letters Patent, is-

The fastening D, consisting of a cylinder adapted to fit into a round hole bored in the wood, constructed with steps on its upper surface, cross-bars a Z) on said steps, lips c c at the outer end, and the downwardly-projecting lug f at the inner end, as shown and described and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

FRANK L. ROSENTRETER.
