WINDOW BAR.

APPLICATION FILED snmzo, 1909.

To all whom it may concern:

UNITED STATES PATENT OFFICE.

GEORGE L. FOX, 0F ALBANY, NEW YORK.

WINDOW-BAR.

Be it known that I, GEORGE L; Fox, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Window-Bars; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel device for barring windows, with one or more bars as needed, to afiord protection from intruders, or to prevent persons inside falling out.

The invention is embodied in a bar which may be made in sections, and is provided with trunnions on its ends to engage in holes or sockets in the bottom rail of the lower sash when raised and in the window sill, and provided with flanges on its ends to afford enlarged bearings against the sill and sash when the trunnions or pins are inserted in holes. And one of the trunnions is pr0- vided with a telescopic spring supported extension so that when more than one bar is to be used in a window, such bars can be readily'inserted in position, or removed, one at a time; without liability of the other bars falling out or becoming displaced while one bar is being inserted or removed. The lower sash is raised and all the bars inserted in place and then they are secured by drawing the lower sash down 11 on the upper ends of the bars and then locking such sash so as to prevent raising thereof, the bars preventing egrees or ingress through the window.

The invention will be clearly understood from the accompanying drawings, in which:

Figure 1 is a view of a window with several of the novel bars in position therein. Fig. 2 is an enlarged View of one of the bars detached, showing the sash lowered in full lines, and partly raised in dotted lines. Fig. 3 is anenlarged sectional view of one of the bars and a complemental extension bar, or section. Fig. 4 is an enlarged sectional view of the telescopic end stud of the bar showing the preferred construction. Figs. 5, 6, and 7 are detail sectional views of the extensible studs, showing various modifications of the construction thereof. Fig. 8 isa detail section on line 88, of Fig. 1.

Each bar 1 may be made of any suitable material, or combination of materials for purpose of lightness and strength, but is Specification of Letters Patent.

Application filed September 20, 1909.

Patented Mar. 29, 1910. Serial No. 518,486.

preferably made of metal and of a length equal to the height to which it is ordinarily desired to have the window opened when barred; but their length may be varied by using extension-bars, or sections, as hereinafter described. Each bar 1 is preferably provided on its ends with flanges 1 to give ample bearing against the window sill S and against the lower rail R of the lower window sash. The bar is provided on its lower end with a small trunnion or stud l and on its upper end with a trunnion or stud 1; these studs being adapted to engage small holes or sockets s, r, in the sill and sash rail respectively; which holes can be readily made in the sash and rail at the desired points with a gimlet or nail.

The upper stud 1 is preferably made extensible or telescopic; and as shown in Figs. 1, 2 and 4: ittelescopes within a cylinder 2 which may be prevented from disengaging the stud by having its lower end contracted-or crimpedas at 2 below the upper end or head 1 of the stud, which head is of slightly greater diameter than the lower part of the stud. The cylinder may be slidably confined on the stud in any other suitable manner, which will allow the cylinder 2 to be raised and lowered on the stud. The cylinder is normally projected or raised by means of a spring 3 interposed between the closed upper end of the cylinder 2 and the upper end of stud 1. The

cylinder 2 forms an elongation of the stud 1 and it enables the bar to be readily placed in or removed from position without danger of any of the other bars falling out, as hereinafter explained. As the necessary longitudinalmovement of the cylinder on the stud is small, the lower end of cylinder may be provided with a laterally projecting finger or flange 2, as indicated 1n Figs. 1 andl, which enables it to be readily grasped and manipulated.

l/Vhen a bar is being placed in position the lower trunnion 1 is first inserted in a hole in the still S, then the cylinder 2 is drawn down on stud 1 and inserted in a hole in the lower railof the raised lower sash, and the sash is then partly lowered, as indicated in dotted lines in Fig. 2, but not suiliciently to engage the trunnion 1. Then another bar 1 can be placed in position by first insertin its stud 1 into another hole in the sill, an then retracting the cylinder 2 on its stud 1 until it can be slipped under the sash rail, and released'to engage its hole therein. The several bars can be successively inserted in position in this manner. After all are in place the sash is entirely lowered until the studs 1 enter the holes in the sash rail and ,the latter bears firmly on the upper end of egress through the window.

When it is desired to remove a rod the lower sash should be unlocked and partially raised until its bottom rail is clear of the studs 1, but still in engagement with the spring projected cylinder 2, as indicated in dotted lines in Fig. 2, and the operator can then grasp finger or flange 2 in the lower end of the cylinder 2 on the bar it is desired to remove, and readily depress such cylinder so as to disengage it from the sash rail,then the bar can be removed, as is evident.

As shown in Fig. 5 the cylinder 2 is slidably connected with the stud 1 by means of a pin 1 transfixing the stud and engaging a slot 2 in the cylinder. 'As shown in Fig. 6 the stud is made hollow as shown at l, and a bolt 2 is slidably confined in the hollow stud by an inwardly turned flange 1 on the upper end thereof as shown, the

bolt being projected by a spring 3.

In Fig. 7 the stud is also shown as hollow, and a bolt 2 is slidably confined therein by a pin 1" transfixing the stud and engaging a slot 2 in the bolt. These modifications illustrate a few of the various ways in which the stud can be made extensible so as to enable the rods to be placed in or removed from position, as above described.

In some cases it may be desired to vary the length of the bars, so as to change the position of the sash. To this end I provide extension bars 1 which haveflanges 1, 1 on their ends, and a stud 1 on one end, and a socket 1 in the other end. In use the extension 1 is connected to one end of a bar 1, by inserting the stud 1 of bar 1 into socket 1 in extension bar 1; and stud 1 can be engaged in the sill. One such extension bar is shown in Figs. 1, and 3.

Obviously by making the bars 1 separate, any desired number may be placed in any given window, and any one or more of such bars can be removed when desired to pass objects through the window without having to remove other bars, and by reason of the telescopic cylinders any rod can be retained in position while other rods are being inserted or removed.

I'Vhile I have described the cylinder 2 as engaging with the sash rail, the bars could obviously be inverted and the cylinders 2 engaged with the window sill.

Having thus described my invention what I claim as new is:
