SASH SEGURI-NG DEVICE Filed Oct. 11, 1953 INVENTORS WITNESSES lk/mwzdfe/zzm Zw za BY 2 5;? m/w WWATTORNY Patented Apr. 17, 1934 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates tosash securing devices, and while we employ the term sash securing devices and shall hereinafter describe a securing device in connection with a sash of the hinge type, it is to be distinctly understood that the securing device may be used with any type of door or analogous member which is to be secured in closed position.

An object of the invention is to provide a securing device in which the sash will be drawn tightly to the jamb and be secured by the positive action of the securing device through the medium of an. operating lever.

A further object is to provide a securing device of this character in which a lever handle is employed to control the movement of an operating lever, the latter fixed to and adapted to turn a shaft having any desired number of pressure dogs thereon so as to positively move the dogs to cause the sash to be drawn into the frame and against the jamb and positively secure the sash in its closed position.

A further object is to provide a sash securing device which embodies many novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawing- Figure 1 is a fragmentary view in elevation illustrating my improved sash securing device;

Figure 2 is a view in section on the line 2/2 of Figure 1;

Figure 3 is a view similar to Figure 2 showing the device in released position;

6 Figgre 4 is a plan view of the bearing bracket Figure 5 is a view in section through the supporting lmee 7.

1 represents a window frame or, more specifically, the jamb thereof, and 2 a hinged sash of the outwardly swinging type. A vertical shaft 3 is located adjacent the free edge of the sash and is turnably mounted in vertical bearings or keepers 4, and on this shaft 3 any desired number of pressure dogs 5 are rigidly secured, these pressure dogs being adapted to engage the jamb or frame 1, as indicated.

A bearing bracket 6 is secured to the sash, and this bearing bracket, illustrated in detail in Figure 4, is of general arch shape so as to straddle the shaft 3, and the ends of the bearing bracket are preferably riveted to a supporting knee '7 which in turn is secured to the sash. The bearing bracket 6 has an integral axle 8 projecting therefrom on which an operating handle 9 is pivotally secured. The axle 8 is disposed horizontally or perpendicularly with respect to the axis of the shaft 3.

We have illustrated the handle 9 as having a hearing 10, and have illustrated the axle as being upset or enlarged at its end, as indicated at 11, with suitable spacing washers 12 on the axle so that the operating handle will be permanently attached to the axle or is free to swing thereon.

13 represents our improved operating lever, which is rigidly secured to the shaft 3 and projects at right angles therefrom. This operating lever 13 has an opening 14 therein which is in the form of a three-way opening shaped somewhat after the manner of a three-leaf clover, andthe operating handle 9 has a finger 15 thereon which is engageable with the lever 13 by virtue of the opening 14, to act on the lever 13, and is located at approximately right angles to the major portion of the handle 9. For clearness of description the three-way opening 14 and the operating lever 13 may be considered as comprising three communicating recesses or notches 16, 17 and 18.

In operation, the finger 15, which is cross-sectionally round in the form of a pin, moves from one recess or notch 16 into the notch 17, and vice versa, and during its passage from one recess 16 to the other recess 17 the finger 15 is accommodated in the recess 18, because of thefact that such a recess is absolutely necessary as the operating lever 13 in its movement defines a path with relation to the pivot or axis thereof in its movement past dead center, which requires the shape of opening or arrangement of recesses as above described. Furthermore, it will be noted that, by reason of the fact that this operating lever 13 is moved past dead center in forcing the dogs 5 against the sash, the securement becomes a positive one and cannot be released by pressure against the sash, but can only be released when the operating lever is swung through its are past dead center, as above explained.

Further, it will be noted that the operating dogs 5 may engage the frame or jamb before the sash 1 is completely closed and thus draw the sash to closed position while the operating lever 13 is being moved past dead center to a positive securing position; in fact, this movement may be at least an inch or possibly more.

It is understood, of course, that our locking device can be used for either wood or metal windows or doors, and can be produced more cheaply and more efficiently than the old type Cremorne bolts. It will also be noted that the operating dogs are swung through an arc of approximately ninety degrees so as to create a clear passage between the jamb and sash, and that the securing device is so simply constructed that it is not apt to get out of order.

While we have illustrated what we believe to be the preferred embodiment of our invention, it is to be distinctly understood that various slight changes may be made with regard to the form and arrangement of parts without departing from our invention, and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

What we claim is:

1. A securing device, comprising a 'turnable shaft, dogs on the shaft, an operating lever on the shaft, a lever handle mounted to move in a plane at right angles to the operating lever, said operating lever having a three-way opening therein, and a finger on the lever projecting at an angle thereto and projecting into the opening in the projecting lever.

2. A securing device, including a shaft adapted to be supported in bearings on a sash, pressure dogs fixed to the shaft and adapted to engage the frame of the sash, an arched bearing bracket secured to the sash and straddling the shaft, an

axle on the bearing bracket, an operating handle pivotally supported on the axle, an operating lever fixed to the shaft and extending at right angles thereto, said lever having a three-way opening therein, and a finger on the operating handle projecting into the three-way opening of the lever and adapted, when the handle is swung, to move the operating lever past dead center with relation to the finger, causing the finger to move into recessed or oifset portions constituting parts of the lever and positively secure the dogs against movement except through the medium of the operating handle.

3. A securing device comprising a turnable shaft, pressure means on said shaft, a radially disposed member on said shaft, said member having an opening therein consisting of three communicating notches, a lever handle movable on an axis perpendicular to the axis of said shaft, and a pin on said handle engaging said member by virtue of said opening to turn said shaft into a position in which said means will exert pressure, in response to the operation of said handle, the pin being received in one of said notches to prevent retrograde turning of the shaft from said position.
