MPROVED SASH-IEASTENER.4

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom. yit may concern:

Be it known that I, DANIEL BULL, of Amboy, in the county of Lee, and State of Illinois, have invented a new and useful Improvement in Sash-Fasteners; and I do hereby declare the following to he a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters and iigures marked thereon, whichv form a part of this specication, and in which` Figure 1 represents a side elevation of my fastener, as applied tothe window;

Figure 2, a vertical sectional AView of the windowcasing, and strip showing the notches in which' the fastener engages;

' Figure 3, a' side elevation of the fastener, detached from the window;

Figure 4, a view of the under side of said fastener;

Figure 5, an edge view of the fastener, looking at the side; and

Figure 6, an edge view, looking atfthe end of the fastener.

The nature of my invention consists in a vibrating bar or lever, in. a sash-fastener; also, in a thumb-4 piece, in combination with said'vibrating bar.; and it further consists in the combination of the thumb-piece, plate, spring, and vibrating bar, constructed and arranged as a window-fastener.

To enable those skilled in theart to understand how to manufacture and use my invention, I will proceed to describe the same with particular-ity.

The sam eletters of reference referto the corresponding parts in the different lfigures.

In the annexed drawings- A vrepresents the window-sash;

B, the window-frame or casing; and

.0, the removable strip which holds the sash in place.

vD is a plate, which is secured to the-window-sah in any suitable way, as by the screws E.'

There is a post, F, attached to the under side of said plate on which a thumb-piece, H, lis placed, it being held in place thereon by the spring J.

To one end'of the thumb-piece Hthere is a projection, K, attached, which extends through the plate D far enough to be lnoved as hereafter described, while the other end vof the piece H projects over the vibrating bar, or stop O.

The vibrating bar, or stop 0, is made with a slot in one side, at or nearits longitudinal centre, which fits on to the cross-piece I. f

This saves making a hole through the bar, and fitting a pin for it to vibrate on.

The bar, or stop O, is held in place, as well as vibrated, as hereafter described, by the thumb-piece HZ There is a slight projection, S, on either end of the bar, or stop O, which strikes against the plate R, to

prevent it from turning, so that the end will lnot proof the bar O, so that it will press it against tl1e win. dow-casing, and cause it to spring into the notches Ti as the sash is raised sufficiently high.

The position the bar Oassumes is shown in fig. 5.

vVhen it is desired to lower the window-sash, the projection K is-inoved down, and the thumb-piece H is thrown over the upper end of the bar, or stop O, and forces the upper end thereof against the window- Qca-sing, so that it projects into the notches U, and locks the window down.

If it is desired to move the window-sash up and Adown without fastening or locking it, the projection K is moved to the centre of the opening or slot in the plate D, asshown infig. 1, which throws the end of the thumb-piece H over thecentre of the bar, or stop O, so that it holds it in ahorizontal position, as shownin ligs. 3 and 4, and neither end will project to catch the notches'.

The spring over Athe thumb-'piece H allows it to give, so that the bar or stopwill operate as above de# scribed.

The thumb-piece H may be made of spring-metal.

My window-fastener is simple, cheap, and durable. It also admits of the operator using bot-h hands to raise the window-sash; for, when the4 thumb-piece is -moved to the desired position, it remains there without being held.

Having fully described the construction and operation of my invention,

Vihat I claim, and desire to secure by Letters Patent, is-.- rf

1. The bar, or stop O, when so constructed and arranged in a sashfasteuer,'that it vibrates upon its centre to projecteither end thereof, substantially as described, to lock the sash up or down, as may be desired. A

2. The combination of the vibrating bar, or stop O,

and thumb-piece H, when so constructed and arranged that one end of the thumb-piece rests upon the bar,

-in y such a way that the bar or stop is vibrated by it Witnesses:
