IMPROVEMENT lN FASTENERS FOR THE MEETING-RAILS 0F SASHES.

Specification forming part of Letters Patent No. 197,848, dated December 4, 1877 application filed November 2, 1877.

the details of construction hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is an end View, partly in section, of my i111 proved sash-retainer; Fig. 2, an inverted plan view; Fig. 3, a side view of the retaining and releasinglever; Fig. 4, 'a perspective view of the same Fig. 5, a section of the base of the retainer; and Figs. 6 and 7, views of detached parts of the device.

The base A is preferably made of the quadrangular shape shown in Fig. 2, with slightly tapering sides and ends.

The'retaining and releasing lever B has at its outer end a suitable knob, a, the opposite or inner end having a collar, d, for bearing on the base, and below the collar a spindle, 0, having at the lower end an enlargement with three projections, f, f and f, as best observed in Fig. 4.

There is in the top of the base an opening, h, Fig. 5, large enough to freely admit the-spindle and its enlargement, after which the retaining-plate D is introduced into its place, as shown in Fig. 2, the central portion of the plate overlapping the projection f of the enlargement, and preventing the withdrawal of the same through the said .opening h.

The retaining-plate is held in place longitudinally by two studs, 1' 1', cast with and forming a part of the base.

The last thingto be done in order to complete the device and retain the parts firmly in place is to apply the spring G, which is introduced beneath lips m m on the retaining-plate D, and bears against the enlargement of the spindle of the lever, the opposite ends of the spring bearing against the projections 19 p on opposite corners of the base.

. middle.

When the lever is moved to a position at right angles to that shown in Fig. 2, the spring will serve to retain it in that position.

The main advantages of my invention are its simplicity and the facility with which it can be put together without any fitting demanding tedious manipulation or expensive machine-work, the only part demanding any work of this kind being the knob a.

The base, retaining-plate, and lever, with its spindle, are crude castings, properly cleaned, and the spring is a simple unfinished strip of steel.

The base is provided with holes for receiving screws, by which it is secured to one sash, the projection q of the lever being arranged to bear on a plate on the other sash.

I claim as my invention- 1. The combination of the lever B, its spindle e and projection f, with the base A and its opening h, and with the retaining-plate D,

arranged to overlap the said projection, all substantially as set forth.

2. The combination of the base A, the enlargement of the lever B, the retaining-plate D, with its lips m, and the spring G, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
