HIRAM ST. JOHN, 0F WILTON, CONNECTICUT.
Letters Patent-No. 109,357, dated November 15, 1870.
iM PROVEM ENT iN WINDOW-FASTENINGS.
The Schedule referred to in these Letters Patent and making part of the same.
.To all whom 'it may concern Be it known that I, HIRAM ST. J ons', of Wilton, in the county of Fairfield and State of Connecticut, have inventedcertain Im provemen ts iu Window-Fastenings, ot' which the following is a specification, reference being had to the accompanying drawing.
My invention relates to sash-fastenings, and the invention consists in applying a locking-spring tothe swinging locking-lever in a novel manner, and so as to hold the lever in position both when the sash is locked and when unlocked, as hereinafter more fully explained.
Figure 1 is a top-plan view, and
Figure 2,y a vertical section, on the line a: a; of iig. l.
In constructing my improved device I provide two plates, C and D, asnsual in this class of fastenings, the plate D being made in theordinary manner, ot' a semicirculalr form, with a raised projecting lip for the locking-lever E to engage under when locked, as represented in iig. 2.
The plate C, to 'which thelever is pivoted, instead of being formed as usual, is made with a projection, laterally at each side, these projections having a ledge on their upper surfaces at the extremities, iu which ledges a notch, a., is formed, as shown in iig. 1, to reccive the spring attached to the locking-le er when swung around, and hold it in place.
The lever E is pivoted to the plate() at its center, and i s pnovided with a hook, e, to lock under the lip of the plate 1) in the usual manner, as represented in tached to the under side ot' the lever E, in front of the point where the rails A and B of the sash abut against each other, and extends out through the hole in the hook e, even with or slightly beyond the end ot' the lever, its end being slightly bent upward to permit the thumb or finger to be inserted uuderit, when necessary, for unlocking it.
A notch is formed in the upper surface of the plate D, at its outer edge, so that when the lever` E is thrown g.
around to lock the parts together, the spring F shall lfall into this notch, and thus prevent the lever from being moved.
This s rinfr F thus serves the two-fold purpose of locking the lever in place to hold the window shut,
and also holds the lever back out of the way when swung around to either side, and thereby dispensing with the raised bar and spring usually applied at the rear end of the lever E.
As lthe spring is fastened to the under side of lever E, and rests against a iiat surface on the same, for
some dist-ance in front of the joint between the rails, it is impossible;l to `unlock it by inserting anything from the outside vbetween the rails, and thus the de- `ing the raised ends with the notches a, and the lever E, with the spring F secured to its under side, extending through a slot in the outer end thereof', andenenga-ging with a notch in the plate D, all substantially as' described. p
' HIRAM ST. JOHN.
