J CHARLES VARA, 0F BUFFALO, NEW YORK.

SASI-LFASTENER.

Application filed April 18, 1918. Serial No. 229,432.

To all whom it may concern:

Be it known that I, JOSEPH CHARLES VARA,

a citizen of the United States, residin "at Buffalo, in the county of Erie, State of ew York, have inventeda new and useful Sash- Fastener; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use thesame.

The present invention relates to a sash fastener, and has for its Object to provide a device of this character which embodies novel features of construction whereby the meeting rails of upper and lower window sashes can be securely locked together, thereby preventing the unauthorized opening. of the window from the exterior of the build ing. 7

Further objects of the invention are to provide a device of this character which is comparatively simpleandinexpensive in its construction, which can be readily applied to the sashes of a conventional window without injury thereto, which can be easily manipulated, which is practically invisible and avoids unsightly and dust catching projections at the top of the lower sash, and which will notinterfere with the necessary tight joint between the meeting faces of the two sashes.

lVith these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a transverse vertical sectional view through the meeting rails of a pair of sashes, showing the sash fastener as applied thereto.

Fig. 2 is a plan view of one of the concaved plates which are applied to the openings at the meeting faces of the two sash rails.

Fig. 3 is an end view of the outer guide sleeve, looking at the same from the inner end.

Fig. 4 is a side elevation thereof.

Fig. 5 is a detail view, partially in section, of the locking bolt and stem, the end Specification of Letters Patent.

portions of the two members being broken away.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to Fig. 1 of the drawing, the reference character B designates a portion of a window frame which is of the conventional construction, and has an upper sash 1 and lower sash 2 slidably mounted therein. A transverse opening 3 is provided in the meeting rail 4 of the lower sash, extending entirely through the same from the front to the rear thereof, while a corresponding socket 5 is formed in the inner face of the meeting rail 6 of the upper sash. It will be noted that the adjacent faces of the two meeting rails 4 and 6 are correspondingly inclined in the usual manner so that a tight waterproof joint will be provided when the window is closed.

Concaved plates 7 are fitted over the openings in the inner faces of the two meeting sash rails, said plates being held securely in position by suitable fastening members 8, and being provided with openings surrounded by inwardly extended flanges 9. These flanges 9 serve to guide the nose of the looking bolt 10 and to provide a solid bearing for the same, so that when the locking bolt is moved inwardly into operative position, as indicated by Fig. 1, the meeting rails of the two window sashes are securely fastened together so that it is impossible to open the window from the exterior of the building. The eoncaved formation of the plates 7 renders it necessary for the plates to be properly seated when applying the fastener to the window, and eliminates any possibility of bulging outer portions in the surfaces of the two plates contacting with each other and preventing the faces of the sash rails from being brought closely together in the manner necessary to provide a waterproof oint.

A guide sleeve 11 is fitted in the outer end of the opening 3 in the meeting rail 4 of the lower sash, said sleeve being carried by an outer plate 12 which fits against the front of the sash and is secured in position by suitable fastening members 13. A stem 14 is slidable through the outer plate 12, being provided at its outer end with a' finger piece 15, and being connected at its inner end to the locking bolt 10. A coil spring 16 surrounds the stem 14 and is interposed between the locking bolt and the plate 12, the tension of the spring normally tending to move the plunger into operative position. A transverse pin 17 is shown as employed to secure the stem 14 to the locking bolt 10, one end of the pin projecting laterally from the locking bolt and being received in a T- slot 18 in the guide sleeve 11. When the locking bolt is pulled rearwardly and rotated to throw the pin 17 into one of the transverse portions of the T-slot 18 the bolt is locked in an inoperative position and the two window sashes can be opened and closed in the usual manner. When it is desired to lock the window, it is merely necessary to rotate the locking bolt to bring the pin 17 into the longitudinal portion of the T-slot 18, whereupon the tension of the spring 16 will move the bolt into operative position and hold it against accidental movement.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with the meeting rails of upper and lower window sashes, the rail of one sash being provided with a transverse opening, while the rail of the other sash is provided with a corresponding socket, corresponding concave plates fitted over the openings in the meeting faces of the two rails and; provided with openings corre-'' sponding to the openings of the rails, said plates being let into the rails so that the outer edges thereof are flush with the rails, fastening members securing the edge portions of the plates to the rails, with the concave faces of the plates facing each other so that they will not bulge and prevent a tight joint between the rails, and a locking bolt slidable through the opening of the first mentioned rail and adapted to engage the socket of the second mentioned rail.

2. The combination with the meeting rails of upper and lower sashes, the rail of one sash being provided with a transverse opening extending entirely therethrough, while the rail of the opposite sash is provided with a corresponding socket, a tubular guide sleeve fitted in the mouth of the opening and formed with a longitudinal slot having an angnlarly disposed end portion, a plate carrying the guide sleeve and closing the mouth of the opening, a stem slidable through the plate, a locking bolt slidable within the sleeve and provided at one end with a recess and at the opposite end with a nose adapted to engage the socket of the other rail, the recess receiving the before mentioned stem, and a transverse pin extending through the bolt and stem and provided with a projecting end which enters the slot of the guide sleeve and is adapted to be rotated in the angular end portion thereof to hold the locking bolt in a predetermined position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
