HENRY XV. BAKER, OF BURLINGTON, 'WEST VIRGINIA.

IMPROVEMENT lN SASH-HOLDERS.

SPEoIFIcA'rIoN.

Be it known that L'HENRY W. BAKER, of Burlington, county of Mineral, State of West Virginia, have invented a new and Improved Sash-Holder and Lock; and I declare the following to be a full, clear, and exact description of same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyin g drawing which forms a part of this speci- Iication.

My invention relates to a secure sash-holder which will always catch, and it is simple and strongin its construction and consists informing, in connection with this sash-holder, a convenient locking device for securing the window when closed, as will be hereafter more fully described.

I n the drawing, Figure 1 is a view of the sash-holder as applied to the upper frame. B is the window-frame B', the groove in which the sash A slides. D is the metal piece or block which holds the latch or pawl E. e is a shoulder, which strikes against the bed-plate D. F His the thumb-piece to unloosen the latch. At the lower part of Fig. 1 is lower sash-holder, differing from the upper by the curved thumb-piece. L is the locking-do g, set e 1s a shoulder, which strikes against the liange m.

Fig. 2 is a sectional view, in elevation, of

the sash-holder with the recesses or ratchets E in the sash. U is the middle strip, shown in Fig. 1, the dotted lines representing the thumb-piece or lever, set into the middle strip C so as to be clear of the lower sash when the latter is raised. e is the shoulder.

Fig. 3 is sectional view of the sash A, showing metal recesses or ratchets.

Fig. 4 is view of the latch in isometrical projection, with a portion of the bed-plate removed so as to expose the latch. The full lines represent the upper, and the full and dotted lines the lower, sash-holders.

I form the bed-plate D of a piece of metal providedwith arecess formed into and through it, as shown in the drawing. This recess is so shaped that when the latch is pressed back into it the whole surface presented to the sash will be Hush or smooth. The bottom part is formed with a bevel extending part of the distance back, as shown in Fig. 2, so that the shoulder e of the latch may rest dat upon it when supporting' the weight of the sash, and thus throw no strain upon the pivot. This block is sustained to the frame by a screw near its bottom end. The latch or pawl is formed of one piece of metal, with an upright piece, E, a transverse bar, G, to carry it clear of the sash, and two arms, H and F. The whole is retained in 'the bed-plate by a pivot which passes through a heel, J, which projects back beyond the balance of the latch, thus throwing its cent-er of gravity toward the sash that it may always fall into the recesses or ratchet. The sash is provided with recesses or ratchets E, which may be oi' metal, or may be simply cut into the sash. The upper sashholder9 is so arranged that the thumb-lever will lie wholly within the middle strip of the frame, so as to be out ofthe way of the lower sash and of the strip it carries on its upper edge. The lower sash-holder is provided with a curved thumb-piece, F', under which the locking dog or bar L may fall, and thus secure the Window when closed. This locking-dog L is preferably set into a bed-plate with a flange, m, so that, when resting beneath the latch F',

its shoulder e rests solidly against the flange,

vided with the curved thumb-latch F, in combination with the locking-dog L with or without bed-plate and ange m, whereby a sash is securely locked in position, all substantially as described and shown, for the purposes set forth.
