FASTENING FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 231,401, dated August 24, 1889.

Application filed April 27, 1880. (ModeL) To all whom it may concern:

Be it known that I, LORENZO D. OLEAVE- LAND, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fastenings for the Meeting-Rails of Sashes, (Case A,) of which the followingis a specification, reference beinghad to the accompanying drawings, in Which- Figure 1 is a transverse section of the meeting-rails of the sash and a sectional elevation of my improved saslrlock in position as when the sash are locked in the window-frame; Fig. 2, a plan or top view of the lock attached to the meetingrails of the sash. Fig. 3 represents the lock-fastening to the vertical bar of a sash as when the sashes are partially open. Fig. 4 is a face view of the catch-plate which is fastened to the central bar of the upper sash. Fig. 5 is a transverse section of the central bar and the catch -plate attached. Fig. 6 is a transverse section of a central bar and a molded catch-plate, to be used where the bar is too thin to receive a suitable face-plate in flat form, as shown at Figs. 4 and 5. Fig. 7 shows a modified form of catch for fastening the end A of the lever catch to the meeting-rail.

The object of the present invention is to provide more convenient means for locking the meeting-rails of window-sashes and locking the sashes together when partially open in the Window-frame.

The invention consists in a box-catch attached to the top side of the upper meetingrail, and a lever-catch pivoted to a frame attached to the top side of the lower meetingrail, and in mechanism for fastening the levercatch to the meeting-rail; also, in means for locking the sash in different positions in the window-frame, so as not to be opened from the outside of the building, and, further, in means for drawing the meeting-rails even during the process of lockin g the sash in the frame.

A 13 represent a catch-lever, which is pivoted to a frame, 0, at D, so as to occupy the position shown at Fig. 1, and also as indicated by the dotted lines E. The end B of the levercatch AB is curved, so as not only to lift theupper sash, but to draw the meeting-rails closely together, and it is so formed and pivoted that it will stand in an upright position (when placed I there) by its own gravity, so as not to lock the sash when they are to move.

The frame 0 is to be securely fastened to the top side of the meeting-rail of the lower sash and a box-catch, II, is to be fastened to the top side of the meeting-rail of the upper sash, as shown at Fig. 1.

The box-catch H is slotted out on the side adjoining the frame 0, to permit the levercatch A B to pass freely in and out, and a hole is formed in the top thereof, that the hooked part B of the levercatch may pass through and lock onto a firm support or hearing, I. This construction is such that when the levercatch is in position, as shown in Fig. 1, the sashes will be securely locked in the windowframe, and such that when the lever-catch is elevated, as shown by dotted line E, the sashes can be moved in the frame; also, such that the meeting-rails may be drawn even by the act of locking the sash--that is, if the rail G should be somewhat lower than the rail F, it is brou ghtinto proper position by the act ofbringing the end A of catch -lever A B down onto the meeting-rail after the hooked part B is made to engage the support I.

To prevent the end B of the lever-catch A B from being disengaged from the support I, the inner end, A, is slotted out vertically at P, and a catch, J, pivoted to a plate, K, attached to the meeting-rail F, is put through the slot and brought onto the metal at the inner end of the slot, as shown at Fig. 1. A spearshaped catch (shown at Fig. 7) may be substituted for the catch J or a loop-catch hinged to the plate K may be used instead of the one shown. The spear-shaped catch is pivoted vertically to a base-plate, and it is to be put through the slot in the end A of the levercatch A B and turned a fourth round to lock the lever.

To lock the sash in different positions in the window-frame, one or more plates, L, provided with a slot, M, is to be attached to the face of the central bar, N, and the lever catch A B locked therein instead of the catch H.

Where the central bar is too thin to receive a plate, L, of suitable width, a plate, 0, molded to conform to the mold of the bar, is fastened to the latter, as shown in Fig. 6, the said plates being let into the wood or fastened to surface of the sash, as most convenient or desirable, cutand they may have any desired form suitable I In a sash-lock, the lever A B, constructed to be engaged by the lever-catch A.
