IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 125,539, dated April 9, 1872.

Specification describing a certain Improvement in Combined Sash-Lock and Stop, invented by J AMEs J. CALLEN, of East Mendon, in the county of Monroe and State of New York.

This invention consists in the construction and arrangement of the lock and stop, as hereinafter described, and also in the means for securing the spindle and making the device burglar-proof.-

In the drawing, Figure 1 is a perspective View of my improved device; Fig. 2, a sectional View of a window with my improvement applied thereto; Fig. 3, a sect-ion of the lock; Fig. 4, a perspective view of the spindle and fastening disk and connecting parts.

A represents the jamb or casing of a window, and B B the sashes. O G are the lockcases, one situated on each side. They are set flush into the grooves or rabbets of the window, so that the sash will run easily up and down. D is the bolt, which rests in the case, and is thrown out against the edge of the sashby a spiral spring, E. The bearing end of this bolt is made with two projecting ribs,

1) b, which are corrugated crosswise, as shown in Fig. 1. The bolt is made hollow inside, and open at the bottom .to admit the cam or bit G, by which it is thrown. It also has atang or projection, c, at the rear, which forms a bearing against the upper side of the case, and allows the bolt to be fully thrown out without any undue strain, and still keep its place. It enables the body of the bolt to be made shorter than it otherwise could be. The bottom of the cam G comes just flush with the bottom of the case, so that the square eye or opening 9 comes in line with a similar eye through the case for the insertion of the spindle H. This spindle is square in cross-section, and extends out through the side of the casin g into the room, where it has a cap or knob plate, I, by which the spindle is turned. This cap is preferably scalloped and milled to furnish suitable hold for the fingers. On the outer side of the casing, and fast thereto, is secured the disk K, through which the spindle passes. Inside this disk rests a right-angled spring, L, fast at one end, and projecting out at the other through a hole in the rim of the disk,as shown at h, the end resting just flush.

The body of the spring rests crosswise in a notch or slot, 1', of the spindle, in which condition the spindle is locked against turning or being pulled out endwise. But when the end of a wire key, M, is pressed into the hole against the end of the spring L, the spindle will then be released, and when drawn out a round portion, k, of the spindle, comes in contact with the spring, which will allow a free turning movement of the spindle, for the purpose of throwing back the bolt to unlock the sash. When pressed in, as before described,

and, with the spring, locked into the notch of sired.

The object of the fastening and unfastening of the spindle, as above described, is to enable the device to be used either as a lock or as a stop for the sash. When the sash is not to be bolted, but is to have a free action to slide up or down, then the spindle is drawn. out so as to turn to throw the lock-bolt back. But when it is desired to lock the bolt in place, then the spindle is forced in and the cap-piece L becomes stationary, and cannot be turned by burglars or others who have no knowledge at what point the end of the spring projects through the 'disk. It is, therefore, practical] y proof against picking by burglars.

The case 0 has a flange, l, by which it is attached to the wood by a single screw. A guard spring, B, which is made from a single loop of spring wire, is attached to the flange, and is made to encircle the front of the caseits lower crossend standing outward, so as to bear against the sash and produce the necessary pressure to just overbalance the weight of the sash slightly, and give it friction moving up or down. In this respect it avoids the use of a weighted sash, and the cross-end m,

being square and unbroken, produces an even and regular bearing upon the edge of the sash that prevents undue roughness or wear. Thls guard-sprin g acts simply auxiliary to the bolt, which is really the stop, and serves to balance the sash in raising or lowering when the bolt is thrown back. Its tendency is to keep a smooth surface upon the edge of the sash and prevent unusual wear while acting as a friction brake 0r bearing.

What I claim and desire to secure by Letters Patent, is

In a combined sash lock and stop, I claim the hollow bolt D, with projection 0, and corrugated face b, the cam G, and the guardspring 1 arranged and operating as herein shown and described.

Vitnesses:

WILLIAM CALLEN, Jr, R. F. Oseoon.
