Original application led October 22, 1909, Serial No. 524,073. Divided and this application filed March 23,

To all lwhom it 'may concern:

Be it known that i, FRAN 1r T. Lirrrx co'r'r, residing at Newark, in the county of Licking and State of Ohio, have invented ce'rtain new and useful Improvements 1n Latches, of which the following is a speciiication.

This invention has for its object to provide a simple and effective construction of latch device for retaining the. fixed and swingable sections of the window frame in alinement with one another.

This application is a divisional part of my co-pending application tiled October 22, i909, sei-iai No. 524,073.

The invention resides in those novel details of construction, combination and arrangement of parts, all of which will be iirst fully described, then speciiically pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figures l and 2, are detail perspective views of a portion of a window frame with my invention applied. Fig. 3, is an elevation of the invention, the fixed frame section of the groove sash receiving members being removed. Figs. ll and 5, are detail sections on the line 4 4 of Fig'. 3 showing the two positions of the latch proper.

Referring now to the accompanying drawings in which like letters and numerals of reference indicate like parts in all of the figures, l is the window frame having the fixed groove sash receiving section l;l and the hinged groove sash receiving section lc. The fixed section l has a beveled lower end at lf and the other section l correspondingly beveled at lg. fl he fixed section la has a channel lb cut in its inner side, adjacent to the frame l, to receive the latch bar el that has an eye through which the pivot screw fc is passed and which has a head Lla to engage the reinforcing plate G of the frame section lg. The latch bar 4f has a depression et" on its side to receive a hump or bow 3b in a leaf spring 3 that is secured at 3a in a recess ld of the frame l., to hold the latch bar in its latching position. Stops 5 5 limit the movement of the bar e.

In operation the parts are normally positioned as shown in l, 3 and Ll, to hold the window frame sections lfL-lb in alinement with one another so the window sashes may be slid up and down. Vlhen the latch bar 4 is lifted, vas shown in Figs. 2 and 5,

Serial No. 551,085.

the section lC may be swung out and the latch bar 4- will be held in its elevated position by the abutment or hump 3b in the spring 3, coming under the latch bar.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of the invention will be readily understood by those skilled in the art to which the invention appertains.

YV hat I claim is l. In a window having a casing provided with a fixed groove frame section and a movable groove frame section for receiving the sashes; means for securing said frame sections in alinement with one another, which means comprises a latch bar pivoted to the window casing between the casing and the fixed frame section to be partly inclosed by the fixed frame section, said latch bar.

having a head to lap over the ends of the movable frame section to retain it in place.

2. In a window having a casing provided with a fixed groove frame section and a movable groove frame section for receiving the sashes; means for securing said frame sections in alinement with one another, which means comprises a latch bar pivoted to the window casing between the casing and the fixed frame section to be partly inclosed by the fixed frame sections, said latch bar having a head to lap over the ends of the movable frame section to retain it in place, and a leaf spring carried by the window casing for engaging the latch bar and retaining it in its different positions.

3. In a window having a casing provided with a fixed groove frame section and a movable groove frame section for receiving the sashes; means for securing said frame sections in alinement with one another, which means comprises a latch bar pivoted to the window casing between the casing and the fixed frame sections, said latch bar having a head to lap over the ends of the movable frame section to retain it in place, a leaf spring carried by the window casing for engaging the latch bar and retaining it in its different positions, and a means for limiting the movement of said latch bar.

i. In a window construction, a casing having a fixed groove sash receiving section and a movable groove sash receiving section, of means for retaining said grooved sections in alinement with one another, which comprises a latch bar pivoted to the Vwindow' using, said iixed groove section bcing cut away to receive said latch bar and partly inclose the same, stops carried by the casing for limiting the movement ot said latch bar, said latch bar having an exposed head to engage the movable section to retain it in position at times, said Window casing having a recess, a leaf spring in said recess for engaging said latch bar to hold it in its ditterent positions.

ln a Winden1 construction, a casing having a ixed groove sash receiving section and a movable groove sash receiving section, of means :tor retaining said grooved sections in alinement With one another', which comprises a latch bar pivoted to the window casing, said fixed groove section being cnt away to receive said latch bar and partly inclose the same, stops carried by the casing 'for limiting the movementof said latch bar, said latch bar having an exposed head to en gage the movable se ition to retain it in position at times, said window casing having a recess, a leaf spring in said recess lior engaging said latch bar to hold it in its diilercnt positions, said latch bar having a recess in one face and said. spring having a h ump or projection to enter said recess when said latch bar is vin engagement With said movable section.
