FASTENER FOR THE MEETING-RAILS OF SASHES.

' SPECIFICATION forming partof Letters Patent No. 423,741, dated March 18, 1890, Application filed May 18,1889. erial No. 311,263. (ModeL) sey, have invented certain new and useful Im-- provements in Sash-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to reduce the cost of construction and to facilitate their application; also, to make them more secure. It consists in the simple construction, arrangement, and combination of parts, substantially as will be hereinafter set forth,and finally be embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a top view of look when closed. Fig. 2 is a top view of same opened. Fig. 3 is an elevated cross-section of lock closed, taken through line X, Fig. 1. Fig. 4 is a cross-sec tion of end of plate A, Fig. 1, taken through line Z, showing steady-pin 'L', of which one or more may be used on each plateA and B, the object of which will be readily seen.

In applying the lock the pins i are driven in the wood at the places marked by the marker, the central screwtaking the center, the marks being made accurate. The screw goes straight down into the wood, the marker being adjusted to the exact fitting required .for theholding of the sashtight together,

causing the right amount of strain. This marker is necessary with steady-pins. The central screw, passing as it does through the center of socket 1' on lever c and thimble k of plate A, has only to hold said thimble and acting as a substitute for screws; but screws can be used instead and a rivet can hold the lever to its plate. Plate B has a similar thimble to plate A, on which socket r of disk D revolves. They are held together in the same manner as the lever and its plate, having also similar steady-pins. I

Plate 13, Figs. 1 and 2, has a raised surface n, leavingroom between plate B and disk D to the right of line n n for the locking-lever to pass under the disk. The action is this: To look the device, take hold of the lever and pull it onto the disk until it engages with it. The lever and disk travel together till they strike a suitable stop, (here represented as n.) This stop being past the line of the two screws or and a or central line X, the draft holds the lock firmly closed. The outer surface of disk D (or edge) is here represented as having a series of notches; but a smooth edge can be used on the disk. The lever and disk here have a side motion; but I find a perpendicular motion does not interfere with the working of the device. The lever works equally well over as well as under the disk.

To prevent the look from being opened by burglars from without, I use on the lower sash a plate with a projecting safety-check H,which lies across the joint of the sash. This check, when the lock is closed, is directly under the lever, and being rigid it cannot move, and thus being on the joint under the lever the lever cannot be moved.

WVhen the lever is opened to keep it from striking the glass I employ a stop 19, against which the lever strikes. A lug or teat s can be used to stop it the other way, if desired, over which the lever can be lifted when used; or both stops can be in one lug, if desired.

A marker of some kind of material being necessary, I have constructed one to conform to the location of the steady-pins and screws, and the joint of the sash being made to facilitate their application, it thus becomes a necessity to the proper adjustment of this invention. The steady-pins save screws and time. The lock is simple and the application simple. no springs, no rivets. Parts can easily be replaced withoutloss to the balance of the lock. The right edge of projection H can be depressed and allow the lever to ride upon it in closing the lock, and thus close the sash at The lock is ornamental. It is durable- 5 the same time. The projection H should be long enough to reach to the lever when it is open. I

These fasteners are suited to blinds and 5 boxes as well as windows and doors.

I claim 1. In a sash-lock, a disk-plate having acentr'al hole large enough to admit a central screw,

bend to take around central screw or thimble, substantially as shown and described;

3. In a sash-lock, plate A and its thimble,

steady-pins, lever, and stop-post, in combination with plate 13 and its disk, steady-pins, and check H, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of May, A. D. 1889.

JOHN J. CQWELL.
