WINDOW GUARD Filed sept. 8. 1939 fig, a.

Patented Dec. 1, 1942 WINDOW GUARD Ormonde C. Becker and Ellsworth J. Becker, Chicago, Ill.

Application September 8, 1939, Serial No. 293,913

(Cl. 2071) l 1 Claim.

Our invention relates to an improvement in window guards and has for one purpose the provision of a window guard which shall be cheap to manufacture, easy to apply, simple in structure and strong and eiiicient in operation.

Another purpose is the provision of a window guard which cannot readily be tampered with or opened by a child.

Another purpose is the provision of a window guard which can be shipped in compact form for home assembly and application.

Another purpose is the provision of a window guard which is yieldingly located in position.

Other purposes will appear from time to time in the course of the specification and claim.

We illustrate our invention more or less diagrammatically in the accompanying drawing wherein:

Fig. 1 is a partial inside elevation of a window frameand window showing the guard in position;

Fig. 2 is a section at the line 2 2 on Fig. 1; and

Fig. 3 is a section similar to Fig. 2 showing the method of installing the guard.

We illustrate our window guard as applied to or within the outer channel of the conventional window frame.

Like parts are indicated by like symbols throughout the specification and drawing.

Referring to the drawing, the Window frame proper is indicated as I. 2 is the outer, and 3 the inner bounding ledge or projection of the outer channel 4 of the frame. 5 indicates one vertical side element of our window guard, and 6 the opposite. The member 5 is herein shown as having apertures 1, none of which pass entirely through the upright.

The apertures 8 of the opposite upright or side frame member 6 pass entirely therethrough. We illustrate the use of a plurality of cross pieces 9, herein shown as four in number, it being realized that any suitable number may be employed. The members 9 may be made of stock of any suitable shape. If wood is employed as the material of our device, they may be made, for example, of round stock or doweling.

We illustrate the upper and lower of the members 9 as having secured to the ends thereof and coiled thereabout coil springs I0. It will be observed that when the parts are assembled with the upright 6 threaded upon the ends of the members 9, the free outer ends of the springs IIJ thrust against the upright 6 and urge it away dow frame. The result is a locking effect, which keeps the parts normally rmly locked in relation to the window frame.

If we wish additional securing means, as where our device is employed with a wooden window frame, we may employ any suitable screws I2, I3, which may pass, respectively, through the uprights 5 and 1, and may be screwed into the window frame. This is impractical where our device is employed with metal window frames, and the springs in such oase are normally suiiicient.

We may also employ any suitable removable limit members or cotter pins I4, which may be passed through the horizontal members 9, aftery the assembly is made, and installed in the window, in order to prevent the upright 6 from being withdrawn along the cross pieces 9 sufciently far to free the device from the channel of the window frame, in which it is seated.

We thus provide three locking or securing means, the springs I0, the screws I2, I3, and the cotter pins I4, which may be used either separately or together.

It will be realized that we may employ any suitable material, but we illustrate our invention as manufactured of wood.

It will be realized that whereas We have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of our invention. We therefore wish our description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting us to our precise showing.

We claim:

In a readily demountable window guard adapted to seat in the opposite channels of a window, a vertical upright member forming one end of the guard, and adapted to seat in one such channel, said member having a plurality of parallel horizontal vertically aligned apertures` extending entirely therethrough, a second vertical upright member adapted to form the opposite side of the guard and to seat in an opposite channel, said second vertical member having formed therein a plurality of parallel horizontal vertically aligned apertures alinged with the apertures of the first mentioned vertical upright member but terminating short of the outer face of said second vertical member, a plurality of horizontal rods each freely slidably penetrating, at each end, one of said apertures in each Vertical upright memfrom the opposite upright 5 and toward the win- 55 bers, and yielding means interposed between one or more of said horizontal rods and the first mentioned vertical upright member, said yielding means being adapted to urge said vertical upright member along said rods and away from said last mentioned vertical upright member, whereby the two vertical upright members are held seated in the opposite channels of a window, the upright members and the rods being freely slidably separable when the guard is removed from the window, said yielding means being in the form of springs coiled about said rods, one end of each of said springs being permanently secured to the rod about which the spring is coiled, the free end of the spring being opposed to the rst mentioned vertical upright member.
