This invention relates to a window pivot and lock or reversible window appliance.

It is an object of the present invention to provide a window pivot and lock wherein there is provided in each sash of the window construction and at each side thereof a lock device including a channel member with a groove therein for receiving the edge of a fiat plate adapted to be extended in and out of a groove on the side edge of the sash by a turn key device, the groove being provided in a member vertically adjustable in the window frame and connected to a sash weight.

Other objects of the present invention are to provide a pivot and lock device for windows which is of simple construction, inexpensive to manufacture, provides a neat appearance, easy to install within the window frame and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a front elevational view of window sash mounted in a window frame and the sash including the pivot and lock device of the present invention.

Fig. 2 is an enlarged fragmentary and sectional view taken through the side of the window frame and of the sash with portions broken away and shown in section, with the channel in place and the window sash pivotally connected through its pivot pin therewith and the sash weight extending through an opening in the window frame.

Fig. 3 is an enlarged fragmentary view of the side of a window released from the channel and pivoted outwardly.

Fig. 4 is a transverse sectional view taken on line 44 of Fig. 2.

Fig. 5 is a fragmentary and perspective view of the lock device carried on the side of the window sash and showing its locking plate within the groove on the sash, from which groove it is extended for engagement with a groove in the channel.

Referring now to the figures, represents a window opening having the usual guide pieces I I, I2 and I3, Fig. 4, in which the window elements I and I5 are raised and lowered.

According to the present invention, there is disposed between the guides a metal channel It to which the window elements are connected by a pivot pin ll. Each window element has a {tame including a side piece l8. In this side 1 Claim. (01. 20-49) piece there is a rece'ss [9 adapted to receive a fastening plate 2| for securing the pivot pin I! to the side of the window element. Screws 22 are extended into the sash to secure the plate 2| thereto. The channel l6 has a hole therein through which the pivot pin [1 is extended. About the pivot pin and within the channel is a washer 23 and a T-plate 24 connected to the pivot pin and made secure therein by a nut 25.

From the T-plate 24 there is a chain 21 which may be connected to a sash weight 28 operating in an opening 29 in the side of the window. The channels 16 can slide between the guides in the same manner as with the standard window sash the edges thereof slide between the window guides.

The channel l6 has a longitudinal groove 3| extending along its external face into which a locking plate 32 may be extended whereby to secure the window element against pivotal movement on the pin H.

A groove 33 is provided along the sides of the window element to receive the looking plate 32 and the same will be extended from this groove into the groove 3| of the channel. The plate 32 has a projection 34 which is attached to a lock cylinder 35. This lock cylinder can receive a key 36 and when a key is turned, the plate 32 will be moved in or out of groove 33 to lock or release the window element. The lock cylinder 35 has an eccentric crank pin 31 which extends into a hole in the projection 34 of the plate 32.

The lock cylinder 35 has a flange 38 which extends over the window sash face and is secured thereto by fastening screws 39.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

Having thus set forth and disclosed the nature of my invention, what is claimed is;

A window construction comprising a window frame having vertically extending guide elements, channels slidable in'the frame and between the guide elements, said channels having respectively longitudinally extending grooves offset from the center and running continuously from one end to the other, window elements adjustable in the window frame, a pivot pin extending from each side edge of the respective window elements and into the channel, said win dow elements having longitudinally extending grooves in the respective side edges thereof and ofiset from the center of the window element edges, said grooves in the window element being offset from the pivot pin and extending continuously and substantially from the lower edge of the window element to the upper edge thereof, a long locking plate in each of the grooves of the window elements adapted to be extended therefrom and into the groove of a channel whereby to lock the window element to the channel egainstvangular displacement a lock cylinder adapted to be operated'by a key connected to each locking plate to move the same in and out of the groove in the window element out of and into engagement with the corresponding grooves of the channels and pulleyweight means extending into each channel and connected to the pivot pin, said pulley weight means having a plate and spacing means onthe pivot pin for holding the plate spaced from the inner face of the channel and {mm the groove.
