6 Claims. (Cl. 292-173) This invention relates, as indicated, to a window hold.

A primary object of the invention is to provide a window hold which is extremely simple in construction, consisting of a minimum number of parts, which can be made economically in large quantities, and easily assembled.

Another object of the invention is to provide a window hold of the character described, which is highly efficient in use or operation, functioning to hold a window in any desired position, and obviating the need for sticks or other devices conventionally used to hold a window in cases where the window cord has become broken.

A further object of the invention is to provide a device of the character described, which functions also as a safety device.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a fragmentary perspective view, showing the window hold mounted on a window and in operative condition;

Fig. 2 is a longitudinal cross-sectional view, taken on the line 2-2 of Fig. 1;

Fig. 3 is an elevational view of the release arm, and

Fig. 4 is a plan view of the retractible bar.

Referring more particularly to the drawings, the window hold will be seen to comprise a hollow casing 01' body, preferably made from sheet aluminum or the like, and formed to provide a rectangular top 1, sides 2 and 3, and ends 4 and 5. The sides 2 and 3 are provided at their lower edges with pairs of spaced flanges 6, disposed in planes substantially parallel with the plane of the top 1, and provided with openings 7 for screws or nails, whereby the window hold may be secured to a window.

The top 1 is provided with a central rectangular opening 8, and a portion of the metal used to form this opening is displaced downwardly to provide a partition wall 9, which lies parallel with the end walls 4 and of the casing.

The wall 5 is provided with an opening 10, through which a bar 12 extends for slidable reciprocal movement longitudinally of the casing, the bar bearing against the lower edge of the wall 9. The bar 12 is pivotally and loosely connected at its inner end to a release arm 13, which is provided at its lower end with laterally-extending flanges 14, which are disposed in openings 15 in the side walls 2 and 3, whereby the arm 13 has pivoted connection to the side walls. The arm 13 normally extends angularly upwardly, and is provided at its upper end with a vertically-extending finger-piece 16, which extends through the opening 8 and is formed integrally with the 7 arm 13 A compression coil spring 17 is disposed about the bar 12, and bears at one end against the partition wall'9, and at the other end, against shoulders 18 provided at the junction between the bar 12 and a widened portion 12a of the bar, which lies in the opening 10 in the end wall 5. In the expanded condition of the spring 17, the latter also bears against the inner face of the end wall 5 of the casing.

The bar 12 has a rectangular portion 19 at its outer end, wider than the portion 12a, on which a member 20, formed of latex or similar rubber composition is molded, so as to be securely held by the bar. The member 20 is preferably provided with an end face having vertical 2,699,963 Patented Jan. 18, 1955 splines or corrugations 21, for a purpose to be presently described.

The window hold, as described, is mounted on a window W, adjacent the window frame F,'as by means of screws 22, with the splined face of the rubber member 20 bearing resiliently against the window frame. The pressure of the member 20 on the window frame is sufficient to hold the window against vertical displacement or movement, from any position to which the window has been moved. In order to permit the window to be moved from such position to any other position, the release arm 13 is moved from the solid line position to the dotted line position, as shown in Fig. 2, by causing the index finger of the hand to push against the finger piece 16, thereby pulling the bar 12 to the dotted line position and compressing the coil spring 17 by virtue of the engagement of the shoulders 18 of the bar 12 with the spring. This releases the rubber member 20 from its frictional holding engagement with the window frame, whereupon the window may be moved to another position, and the finger piece 16 released, permitting the expansion of the coil spring 17 to restore the rubber member 20 to frictional holding engagement with the window frame.

The device is extremely simple in construction, consisting of only three sheet metal parts, a coil spring and a member formed of rubber. The sheet metal parts are in the form of stampings which can be made economically I in large quantities, and quickly and easily assembled. To

facilitate assembly of the bar 12 with the release arm 13, the release arm 13 is provided with an elongated slot or opening 23, and the bar 12 is provided with a T-shaped tenon 24 which is passed through the slot 23, with the parts 12 and 13 disposed in planes at right angles to each other, after which the bar 12 is turned degrees, thereby locking the tenon 24 to the arm 13. This eliminates the need for pins, rivets or other fastening means, while at the same time providing a loose pivotal connection of the character desired.

The device is highly efficient in use or operation, and

especially useful in cases where the window rope has become broken, functioning in such cases to hold the window in any desired position, and obviating the need for sticks or rods which are conventionally used under such conditions. While the device has been designated as a window hold, it functions also as a safety device, when the window is fully closed, to prevent entry into the home by lifting or lowering the window from the outside.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A window fastener comprising a casing having a top, side walls and end walls, said top having an opening therein and a flange adjacent one end of said opening extending into the casing, a bar mounted in said casing, said bar projecting through one of said end walls and having a resilient member mounted on the end thereof, said bar having abutment means, a release arm connected to said bar and pivoted on the side walls of said casing and having a portion projecting through the opening in said top, said bar extending through said release arm and being movable longitudinally by said release arm, and a compression coil spring interposed between said flange and pression coil spring interposed between said flange and the abutment means of said bar, said spring normally operative to protect the bar from the casing.

2. A window fastener, as defined in claim 1, in which .said abutment means comprises shoulders on said bar motion connection.

4. A window fastener, as defined in claim 3, in which said bar is provided with a widened portion at one end, and said resilient member is a splined member of a rubberlike composition which is molded on said widened portion of the bar.

5. A window fastener, as defined in claim 4, in which said release arm is provided with laterally-extending flanges, and. the side walls of said casing have openings in which said flanges are received, whereby said release arm is pivotally mounted on said-side walls.

6. A window fastener, as defined in claim 5, in which said arm is provided with an elongated opening and the bar is provided with a T-shaped tenon which may be passed through said opening when the bar is in one position, but which cannot be passed through said open- References Cited in the file of this patent ing when the bar is in a plane at 90 degrees from said 10 2,029,199
