sAsH ATTACHMENT.

Application led January 16, l1923. Serial No. 613,030.

To all 'whom t may concern.'

Be it known that I, JOHN I. Kornns, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in a Sash Attachment, ofwhich the following is a specification. l

The present invention relates: to a sash attachment and has for its principal object to provide means for limiting the relative movement of the upper sash in relation to the lower sash and vice versa whereby suitable ventilation may be allowed in a room and at the same time preventing anyone from entering the room through the window.

Another important object of the invention is to provide a device of this nature which is siinpleand efficient in construction, reliable in operation, easily manipulated, readily attached to various forms of windows, durable, attractive in appearance, and well adapted to the purpose for which it is designed.

YVith the above and numerous other objects in view as will appear as the description progresses, the invention resides in certain novel features of construction and in the combination and arrangment of parts as will be hereinafter more fully described and claimed.

In t-he drawing- Figure 1 is an elevation showing portions of two associated sashes with my attachment fixed to one,

Figure 2 is an elevation showing the attachment,

Figure?) is a sectional view taken longitudinally on line 3 3 of Figure 2, n

Figure 4L is a. detail section taken substantially on the line Li-4i of Figure 2,

Figure 5 is a detail perspective of the movable leaf of the device, and

Figure 6 is a detail perspective of the fixed leaf of the device.

Referring to the drawing in detail it will be seen that the window frame 1 is of conventional construction having slidable therein the upper sash 2 and the lower sash 3,. My attachment is fixed preferably to the upper sash 2 on the inside so as to be capable of manipulation from the interior of a room or the like only.

This attachment consists fixed .leaf

5 and a movable leaf 6. The .iixed.leaf 5.

consists of a body in the form of a plate having one longitudinal edge 7 bent at right angles. The body of the leaf 5 is fixed to the upper sash intermediate its ends at a suitable location by means of screws 8 or in any other suitable manner. A leaf spring 9 is `formed on the body of the leaf 6 adjacent one transverse edge and extends therebeyond. This leaf spring 9 is preferably formed by being cut from the body as is indicated to advantage in Figures Sand 6. At this same transverse edge of the leaf 5 there is situated a pair of sleeves 10, the bores of which are in alignment with each other.

The movable leaf 6 is constructed with a pair of spaced sleeves 11 disposed in align-` ment rwith the sleeve-s 10 and a pin l2 is disposed through these sleeves 10 and 11 so that the sleeves arephingedly connected This movable leaf has itsv to each other. transverse free edge provided with a right angular extension 13 formed integral with which is a partially longitudinally disposed extension 14C. A cam extension 15 is provided at the hinged transverse edge of the movable leaf 6 between the sleeves 11 and extends in an opposite direction lfrom the extension 13. This cam extension is engageable bythe leaf spring 9 as is illustrated in Figure 1. When the leaves are disposed as disclosed in Figure 1 the sashes may move freely in relation to each other but when the parts are disclosed as shown in Figure 3 the movement of the sashes is limited '1n respect to each other and it is to be noted that the edge fits over the adjacent edge of the leaf 6 and braces the same. A slot 2O is provided in the leaf 6 for receiving the spring 9 as is seen in Figure 3. The spring- 9 holds the movable leaf 6 in either an extended position in relation to the fixed leaf 5 or superimposed on the fixed leaf.

Although I have described myl invention with some degree of particularity it is to be understood that the present embodiment has been only described and illustrated for the purpose of illustration and by way of example and that numerous changes in the details of construction and in the combination and arrangement of parts ma: v`e re- An attachment of the class described ini cluding a. fixed leaf and a movable leaf hinged together so that the movable leaf may swing to a position in substantially the same plane with the fixed leaf or to a position superimposed on the ixed leaf7 said movable leaf provided with a longitudinally extending slot and an extension disposed laterally at one end of the slot,

said fixed leaf provided with a spring eX- 15 movable leaf when superimposed on the 2U fixed leaf.

In testlmony whereof I affix my signature 1n presence of two witnesses.
