HARRY E. EssIe, OF CANTON, OHIO, AssIGNOR TO THE ESSIG PIVOT WINDOW COMPANY, OF OANTON, OHIO, A CORPORATION.
REVOLVING-WINDOW STRIP.
SPECIFICATION forming part of Letters Patent No. 728,690, dated May 19, 1903.
Application filed December 4, 1902. Serial No. 133,861. (No model.)
To all whom it may concern:
Be it known that I, HARRY E. ESSIG, a citizen of the United States, residing at Canton, in the county of Stark and State of .Ohio, have invented a new and useful Improvement in Revolving-WVindow Strips, of which the following is a specification.
My invention relates to the strips to which a revolving window-sash is pivoted on each way on its pivot; Fig. 3, a fragmentary View showing the detail of the pivotal connection; Fig. 4, a fragmentary perspective view of the sash and strip and pivotal connection, showing the manner of bending or curving the strip; and Fig. 5, a cross-section ofthe sash side bar and the adjoining strips.
In this type of window the sash 1 is pivoted on its horizontal axis to the strips 2, and the adjoining faces of the sash and the strips are corrugated or grooved, as at 3, so that when the strip is closed in its normal position against the sash these corrugations or grooves engage each other, as shown in Fig. 5.
In the pivotal connection at of the sash with.
the strip is provided a spring, as 5, which permits the strip to be forced away from the sash by the rotation of the latter, the sashstrips being held by the frame-strips 6, thereby disengaging the corrugations or grooves and permitting the rotation of the windowsash on its pivots. A
The spring 5 acts to hold the stripclosely against the sash at or near the pivotal point at all times,and various devices have been used to hold the ends of the strips closely against the sash whenthesashandstripsarejoined lengthwise. Among the methods of accomplishing this is by forming-the strips so they will bend or curve inward at either end, by which bending or curving they are always held in close contact with the edge of the sash when the middle of the strip is forced against it 'by action of the spring 5 or otherwise. It has been usual to so form the strips by sawing or cutting them in a curve or by merely bending them in that direction; but it has been found that a strip so formed will not hold its curve and will therefore cease to be effective.
I bend or curve the strip by cutting one or more wedge-shaped notches 7 across the outer side and by forcing or pressing into these notches similarly-shaped and slightly larger wedges '8, which act to bend or curve the ends of the strip inward. One or more of these notches and wedges are preferably used either way from the central or pivotal point of the strip. The wedges 8 retain their places in the notches by friction, or-glue can be used to increase the adhesion; but to more positively hold the wedges in position the staples 9 are preferably driven into the strip astride of the wedges. By the use of these expanding wedges there is a positive bend or curve given to the strip which cannot be overcome except by'permanently disturbing the natural resiliency of the wood. 7
What I claim as my invention, and desir to secure by Letters Patent, is
1. A window-strip, wedge-shaped notches across said strips,and slightly larger simi larly-shaped wedges forced or pressed into said notches, thereby bending or curving said strip.
2. A window-strip, wedge-shaped notches across said strip, slightly larger similarlyshaped notches forced or pressedinto said notches and staples driven into said strip astride of the wedges.
In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
