UNITED STATES TURNER CLAY RUSH, OF LEXINGTON, KENTUCKY.

WIND OW GUARD.

Application led April 18, 1'922.

To all whom t may concern.'

Be it known that I, TURNER C. RUSH. a citizen of the United States, and a resident of Lexington, in the county ot Fayet-te and State oiE Kentucky, have invented a new and Improved lVindow Guard, ot' which the following is a full, clear, and exact description.

This invention relates to improvements in window guards, an object or' the invention being to provide a device of this character capable of adjustment to suit various sized window frames.

A further object is to provide a window guard equipped with anovel form of latching and locking means for effectivelyzpreventing its unauthorized removal from a window frame.

Still another object is to provide a device of this character, which is collapsible so that it will occupy a comparatively small amount oi' space when not in use, a device which will be simple and practical in construction, easy to apply and remove7 serviceable in use, and capable of being manufactured with economy.

With these and other objects in View, the invention consists in certain novel features or' construction and combinations and arrangements oi' parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in side elevation showing my improved window guard in applied position;

Figure 2 is a transverse sectional view on the line 2 2 of Figure 1;

Figure 3 is a sectional view on the line 3 3 of Figure 1;

Figure 4 is a fragmentary detail perspective view illustrating a modified form ot lock; and

Figure 5 is a detail sectional view showing the construction or' the pivot pin which connects the two locking parts.

Referring in detail to the drawings, I have used nthe reference numeral 1 to designate a window frame and the reference numeral 2 to indicate my improved window guard which is in the form of a collapsible Jframe. I prefer to use a lazy tong construction as shown, but any collapsible eXtensible frame of suficiently strong construction ma y be used for the purpose without departing from the invention. At each corner of the frame 2 a bolt 3 is pivoted thereto.

Serial No. 554,654.

When the guard is in extended position these bolts are adapted to enter sockets or escutcheons 4 provided for their reception in the window frame.

The extension or unfolding or" the tram is limited by a pair of locking arms 5 and 6, each having one end pivoted, as indicated at 7, to the intermediate portion of opposite ends of the frame. The other ends of these arms are pivotally connected to each other. This connection is made by a stud 8 on the arm 6 which 'is adapted to selectively enter any of a series of perforations or openings 9 in the arm 5 to pivotally connect the two arms adjacent their free ends. This stud is preferably formed with a cutaway portion 10 adapted to receive the arm 5 when the arm is fully extended, as indicated in Figure 5, so that there is absolutely no danger of the stud being forced out of the perforation or opening in which it is located.

The plurality ot' openings 9 in 'the arm 5 are of course i-'or the purpose of adjusting the window guard to window trames of various sizes. The arm 5 at its free end is provided with an integral U shaped bracket 11 adapted to straddle and embrace the intermediate portion of the arm 6, whereby to limit the pivotal movement of these arms. The free ends of the arms of the bracket 11 are perforated, as indicated at 12, to conveniently receive a padlock 13 for locking the arms against accidental release to collapse the frame 2. An angular bracket 14 secured to the frame 2 adjacent its intermediate portion overlaps the free ends oi both the arms 5 and 6 and prevents their being laterally bent or buckled.

In the event that it is inconvenient or unnecessary to use the lock 13 the outer ends or' the arms 5 and 6 may have a slot and pin connection, as indicated at 15, with the trame 2 and pivoted latches 16 provided at the ends ot the arms may be utilized to lock against the pins 7 and hold the trame in :fully extended position with the bolts 3 in place in the sockets 4.

In Figure 4 of the drawings I have illustrated a slight modilication wherein the arm 17 corresponding to the arm 5 carries a U shaped bracket 1S at its free end adapted to embrace the other locking arm (not shown) and any conventional type of lock 19 carried by the free end of the arm 17 may be utilized for locking the arms together, thus doing away with the necessity of a padlock.

From the foregoing description it Will be readily seen that in order to remove the Window guard it is merely necessary to remove the padlock 13 and pivot the locking arms 5 and 6 upon the stud 8, whereby to effect collapsing of the frame 2 and retraction of the bolts 3 from the sockets 4.

I have illustrated one of the preferred embodiments of my invention, but it is to be understood that numerous slight changes and alterations might be made in the general form and arrangement of the parts described Without departing from the invention, and hence I do not Wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such slight changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim:y

l. A guard of the character described, comprising a frame formed of a plurality of bars pivoted together, bolts pivoted to the free ends of the bars at. each side for engaging recesses in a frame, a pair of locking bars adjust-ably pivoted together at one end and having their other ends pivotally mounted on the pivots connecting the bars at the sides intermediate of the top and bottom of the frame, one of the said locking bars being provided at its end with a U-shaped bracket embracing the other bar, and a lock associated with the bracket for locking the said locking bars together.

2. A guard of the character described, comprising a frame formed of a plurality of bars pivoted together, bolts pivoted to the free ends of the bars at each side for engaging recesses in a frame, a pair of locking bars adjustably pivoted together at one end and having their other ends pivotally mounted on the pivots connecting` the bars at the sides intermediate of the top and bottom of the frame, and means cooperating With said locking bars for locking the frame eX- tended With the bolts in the said recesses.

8. A guard of the character described, comprising an eXtensible frame formed of pivoted bars, devices at the ends of the frame on pivots connecting bars of said frame for pivotally connecting the same to its support bars pivotally mounted at their outer ends to the outer ends of the frame, one of said bars having a series of openings therein, a pin projected through the other of said bars and into any of said openings, said pin having a recess therein receiving a Wall of an opening to hold the bars against independent lateral movement, a bracket on the intermediate portion of the guard receiving both bars, and locking means securing the bars against pivotal movement.

4. A guard of the character described, comprising an extensible frame formed of pivoted bars, devices at the ends of the frame for pivotally connecting the same to its support, bars pivotally mounted at their outer ends to the outer ends of the frame on pivots connectingbarsofthe said frame, one of said bars havinga series of openings therein, a pin projected through the other of said bars and into any of said openings, lsaid pin having a recess therein receiving a Wall of an opening to hold the bars against independent lateral movement, locking means securing the bars against pivotal movement, and a bracket on the intermediate portion of the guard receiving both bars and preventing lateral movement of said bars.
