FASTENING IEEANS' FQR WINDOWS.

Application filed July 21, 1917.

To all whom it may concern:

Be it known that I, WINTER WV. Mrnns, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fastening Means for lVmdows, of which the following 18 a full, clear, and exact description.

The invention which constitutes the sub- Figure l is a vertical cross-sectional view of the ordinary Austral window showing my invention applied thereto.

Fig. 2 is an enlarged view of the meeting rails of the two sashes showing my improvement also in cross section.

Fig. 3 is an end view of the fastening means.

Fig. 1 is a cross section thereof on the line -'l% of Fig. 2.

Fig. 5 is a cross-sectional view of the ordinary Austral window illustrating a slightly modified form ofmy invention.

Fig.8 is an enlarged view thereof with parts broken away to show detailed constructions of Fig. 5.

Fie'. 7 is a top plan view and Fig. 8 is an end view of the modified form shown in Fig. 5.

Fig. 9 is a perspective view of the construction shown in Figs. 1 to i. inclusive.

Referring to Figs. 1 to a in detail, the reference numeral 10 designatesa frame in which the two sashes '11 and 12 are mounted, the former being provided with sliding pivots at the top and the latter with sliding pivots at the bottom. These two sashes are pivotally connected to balance arms 13 (one being shown) so that when one of said sashes is moved the other is simultaneously moved with it. The details of construction and operation will be clear from the prior reissue patent of E. G. Abell, No. 12,048, and

the patent to A.- Knox 8215510, to which reference is hereby made.

Located upon the meeting rail 14 of the lower sash is secured the base member 15 of the fastening means. This member 15 is provided with a horizontal perforation :16 throughwhich the secnringboltli is adapt- Specification of Letters Patent.

ed to project, the outer end of which is pro vided with a pivoted camming or tightening member 18 and the inner end of which is provided with a hook adapted to be cammed aipwardly by, and to engage over, the keeper plate 19. The bolt 17 is provided with a shoulder 20, and interposed between this shoulder and the base member 15 is a spiral spring; 21 which serves to maintain the bolt at its extreme inward position whenever the camming member 17 is in the dotted line position shown in Fig. 2.

The base member 15 is provided with a counter-bore 22 so as to permit a movement of the inner end of bolt 17 in a vertical plane.

-F 2 shows the improved fastening means in normal position with the sashes closed. When it is desired to open the sashes any suitable instrument is made to engage with the power of the spring 21, will be moved inwardly to the dotted line position shown. If the movement of the (ramming member 18 is continued this movement will be im-- parted to the extension 23 and cause the inner end of bolt 17 to move sufliciently in a vertical direction to permit the said bolt and said keeper plate 19 to be out of each others path of movement as the sashes are being opened.

From the above description it will be seen that when the sashes are moved to closed position the member 18 will be in the dotted line position, illustrated in Fig. 2, and the engagement of the bolt 17 withthe keeper plate 19 will be efiected automatically. After this engagement the sashes cannot be opened from the exterior; in other words, they are locked in closed position. If it is desired. to open the sashes a downward pull from its dotted line position shown in Fig. 2 of the member 18 will be necessary; This downward pull of the member 18 is imparted to the extension 28 and results in an upward movement of the inner end of the bolt 17. On the other hand, if it is desired to effect an air-tight engagement between the meeting owingito the eccentric movement ofthe ears 24 about their pivotal points, the base member 15 and keeper plate 19 will be drawn toward each other, thus effecting a corresponding movement toward each other of the meeting rails of the sashes.

It is clear from the above description and the accompanying illustrations that the improved latching device is particularly desirable where the meeting rails are out of reach of the operator, as the same are as readily operable by means of a suitable pole as they are when-manipulated directly by the hand of the operator. 4

In Figs. 5, 6, 7 and 8 is shown a modified form of the invention and designed to be used, for instance, where the windows are out of reach of a hook. In this case the windows are opened by means of a cord 28 attached to a member or arm. 25 which is secured to the hook 17 by means of a suitable pin 26 which not only passes through said members 17 and 25 but also through perforations 27 in the housing 15. When thus assembled the hook member 17 has only a pivotal movement about the pin 26 as a center but it will be clear from the above description that the only changes necessary in the substitution of the arm 18 for the arm 25 is the provision of perforations 27 in the body 15 and a pin sufficiently long to have bearings in the perforations 27 in the hook member 17. The opening of the windows is accomplished by exerting a pull upon the cord 28. When it is desired to close the windows it is only necessary to exert a pull upon the cord .29 which is connected to the outer sash, as will be understood. The spring 21 serves, as it does in Figs. 1 to 4 inclusive, to maintain the bolt member 17 in a substantially horizontal position,that is to say, in substantially the position as indi cated, for example, by the full lines in Fig. 6, thus enabling the said bolt member to automatically engage the keeper plate when the sashes are moved from open to closed position.

What I claim is:

1. An improved window latch, comprising a keeper plate adapted to be secured on the meeting rail of one sash, and a bolt member adapted to be supported on the meeting rail of the other sash and normally engaging said keeper plate, in combination with means including means pivoted to the bolt member adapted to move the latter first longitudinally and then vertically with respect to the meeting rails to unlatch the same.

2. An improved window latch, comprising, in combination, a keeper plate adapted to be secured on the meeting rail of one sash, and a spring pressed bolt member adapted to be supported on the meeting rail of the other sash, and normally engaging said keeper plate, in combination with means including means pivoted to the bolt member adapted to move the latter first longitudi nally and then vertically with respect to the meeting rails to unlatch the same.

3. An improved window latch comprising a keeper plate located on the meeting rail of one sash, a base member fixed to the meeting rail of the other sash, and a plunger or bolt carried by said base member normally in looking engagement with said keeper plate, an operating lever pivoted to the bolt for oscillating the latter and provided with a cam surface thereon cooperating with said base member for moving the same longitudinally in one direction, and means cooperating with said base member for moving said bolt longitudinally in the other direction.
