WINDOW.

SPECIFICATION forming part `of Letters Patent No. 57 5,188, dated January 12, 1897. Application filed February 29, 1896. Serial No. 581,289. (No model.)

T0 all whom it may concern.-

Beit known that I, MARY VEST, of Birmingham, in the county of J efferson and State of Alabama, have invented certain new and useful Improvements in Windows, of which the following is a full, clear, and exact de scription.

The object of this invention is to provide a superior window of that class in which the windows may be adjustable vertically and axially on a horizontal pivot. These ends I attain by weighted chains, a sash, bolts for connecting the sash with the chains, which bolts are vertically movable and on which bolts the sash is capable of axial adjustment, and by a fastening device by which the sash may be held incapable of axial movement. With these means the sash may be freely moved in the frame or easement of the window and turned on its pivot to open the window.

The invention consists in certain combinations which will be fully described hereinafter and nally embodied in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a window embodying one form of my invention.. Fig. 2 is a sectional view of the same,lookin g down upon the two sashes. Fig. 3 is a similar view taken on the line 3 3 of Fig. 1. Fig. 4

is a detail perspective of the cleat for locking the window-sashes shown in Figs. 1 to 3, and Fig. 5 is a detail perspective of the lockingblock used in connection with the cleat shown in Fig. 4.

The window frame or easement 10 is provided with two vertical slots at each side, in each of which slots the bolts 16 are vertically movable, said bolts having their outer ends respectively connected with the rings a, in turn attached to the chains 14, rolling over pulleys 15, carried bythe easement 10, the chains having weights 11 connected thereto. Pivotally connected to the inner ends of each pair of bolts 16 are the

sashes

12 and 13, which are in Figs. 1 to 3 duplicates in construction. Each sash has a locking-cleat 17 at each inner side,and these locking-cleats are provided with reduced ends 17 "L, slidingin slots formed in the upper and lower rails of the sashes. The cleats 17 are adapted to move intovvertical grooves 17", formed in the Casement, and by these means 'the window-sashes will be held incapable of movement on the bolts 1G. It will be seen that the sashes may move vertically when the cleats 17 are engaged with the grooves 17.

lVhen the cleats 17 are engaged with the grooves 17h, they are held in such position by means of blocks 1S, connected to the windowsashes by chains, said blocks heilig inserted in the openings or slots in the window-sashes, so as to prevent the return of the cleats. As

yshown in Fig. 4, the cleats 17 are provided with packing-strips l), by which an air-tight connection with the sash is eifected.

Pivotally mounted on the window-easement are hooks 19,V adapted to engage in notches (not shown) to be produced in the windowsashes, whereby the sashes maybe held hori- -ing-cleat slidable on the sash and capable of engaging the leasement to hold the sash from rotation, and a block iiexibly connected with the sash and capable of engaging the lockingcleatto hold the same in position, substantially as described.

2. In a window,the combination with a window-frame having two vertical slots and two vertical grooves, of bolts respectively Inovable in the slots, a window-sash pivotally connected with the bolts and having slots at each end of its upper portion, two locking-cleats, the ends of which are reduced and respectively tted within the slots, the lockingcleats being capable of movement on the sash to extend into the grooves, and blocks flexibly connected with the sash and capable of engaging the locking-cleats to hold the same in position, substantially as described.

3. The combination with a WindoW-caseand out of the easement-grooves, and means ment having grooves in its Stiles, and two 1onfor detaohably securing.;` the looking-cleats in gitudinal slots' therein, of sashes having opthe grooves, substantially as described. posite pivot-bolts siidable in the slots of the oasementveighted iiexible oonneotions,rings MARY WEST. in Jhe ends of said connections engaging the Vitnesses:
