SASH-FASTENERf SPECIFICATION forming part of Letters Patent No. 446,969,dated February 24-, 1891.

Application filed October 23, 1890. Serial No. 369,053. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES ALVIN FRIS- BIE, a citizen of the United States, residing at Stanberry, in the county of Gentry and State of Missouri, have invented a new and useful Vindow, of which the following is a specification.

The invention relates to improvements in windows.

The object of the present invention is to provide simple and inexpensive means for operating window -sashes and controlling the same and locking them when closed.

The invention consists inthe construction and novel combination and arrangement of parts hereinafter fully described, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a window provided with my improve ment. Fig. 2is a vertical sectional view. Fig. 3 is a horizontal sectional View on line x as of Fig. 2. Fig. 4 is a similar View on line y g of Flg. 2. Fig. 5 is a detail view of the sash.

Referring to the accompanying drawings, 1 designates a window-frame having its upper and lower sashes 2 and 3 provided at opposite sides with longitudinal grooves or bores 4, and havinglongitudinal slots 5 in theirouter edges, which communicate with the longitudinal grooves or openings 4:. Each sash is provided at one side with the said grooves and slots; and these are arranged at opposite sides of the window and have arranged within them a spiral spring 6, which is engaged by a horizontal projection 7, projecting through the slot ointo the opening or bore 4:, whereby when the sash is lowered the spring is compressed and the sash when released will rise and be maintained in an elevated position.

The horizontal projection '7 is preferably mounted in an adjustable slide 8, adapted to be moved longitudinally of the window-frame to vary the tension of the spring.

The 'upper sash is provided at the sides of the frame with vertical series of perforations 9, which are engaged by sliding bolts 10, mounted in bearings 11 of plates 12, arranged at each side of the the lower sash on the upper edge thereof. The sliding bolts are provided intermediate of their ends with depend ing loops 13, which are connected to crankloops 14 of a rock-shaft 15, which has one end the rock-shaft and withdraw the bolts from the perforations 9 of the upper sash.

The vertically-slidin g bar 18 is provided intermediate its ends with an extension 22,

which has an inclined slot 23, which engages a pin 2st, projecting from the cam 25, pivoted to the lower sash, and having a curved edge 26 to engage the adjacent side of the casing and maintain the lower sash at any desired point of adjustment. The rock-shaft 15 is journaled in bearings of the plates 12, and by means of the sliding bolts and perforations of the upper sash the sashes can be readily adjusted relatively to each other, and by means of the cam the lower sash can be secured at any point along the window-frame.

The upper sash 2 is designed to be provided with suitable curtain-fixture brackets to enable the curtain of the window to be adjusted vertically to permit ventilation.

The upper and lowersashes have the springs on one side, and 011 the'other side of each sash are recesses 27, in which are journaled rollers 28, which facilitate the vertical movement of the sashes and prevent them binding.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the operation will be readily understood.

Vhat I claim is 1. The combination, in a window, of the upper sash provided with series of perforations 9, the lower sash, the sliding bolts mounted on the upper edge of the lower sash and arranged to engage the said perforations, the rock-shaft journaled on the upper edge of the lower sash and connected with the sliding bolts, and the vertically-slidin g bar connected to and operating the rock-shaft, substantially as described.

2. The combination, in a window, of the upper sash provided with perforations, the lower sash, the bearing-plates secured to the upper edge of the lower sash, the bolts slidingin the bearing-plates and arranged to engage the said perforations, the rock-shaft journaledin the said plates and connected with the sliding bolts, the cam pivoted to the lower sash and arranged to engage the casing of the window, and the vertically-sliding bar connected with the rock-shaft and the cam, substantially as and for the purpose described.

3. In a window, the combination of the upper sash provided with perforations, the lower sash, the bolts sliding on the lower sash and arranged to engage the perforations, the rockshaft journaled on the lower sash and connccted to the sliding bolts, the cam pivoted to the lower sash and arranged to engage the casin g and provided with the pin fZ-t, and the vertically-slidin g bar connected with the rockshaft and provided with the upwardly-extending projection having the inclined slot to receive the said pin, substantially as described. In testimony that I claim the foregoing as my own I have hereto ailixed my signature in presence of two witnesses.

CHARLES ALVIN FRISBIE.
