Application filed October 27, 1921.- Serial No. 510,961.

the borough of Brooklyn and State of New" York, have invented certain new and useful Improvements in Window Guards. of which the following is a specification.

This invention relates to a window guard of the kind employed to prevent persons from falling through a window.

The primary object of the invention is to place within the easement outside the lower sash a guard that can be readilv ad usted vention, 1 is the casement, 2 the sash guides,

to position and removed therefrom at will.

Another object of the invention is to construct the several parts in such manner that they can be quickly assembled in position without cutting or marr'ing the woodwork or attaching any part thereof to the case ment.

Another object of the invention is to construct the guard in such manner that when the same is adjusted to assembled position it will be sufficiently strong to insure safety under all ordinary conditions.

Another object of the invention is to have the supporting casement strips, the guard rods and the binding nuts thereon so constructed and arranged that the entire guard can be quickly assembled and disassembled.

Other and further objects, including certain features of construction will appear in the specification and be pointed out in the appended claims, reference being had to the accompanying drawings which show the preferred embodiment of my invention.

In the accompanying drawings:

Figure 1 is a front elevation of a window casement showing the guard as placed in position.

Figure 2 is a transverse vertical section of Figure 1.

Figure 3 is a detail perspective view of a portion of the member which fits into the casement and receives the guard rods.

Figure 4 is an enlarged detail showing the guard rod, the nut and how said nut en gages a casement strip.

Figure 5 is an enlarged detail sectional .view of the nut and guard rod.

Figure 6 is a modified form of the nut. In the preferred embodiment of my in- 3 the lower sash, 4 the upper sash and 5 the window sill ofa window of standardiacon struction. I

Fitted within the lower portion of the guideway 4. of the upper sash and within the casementaretwo w oo-den' strips'ior members 6. These stripsare preferablyma de'fof suflicient thickness to project somewhat-in ward beyond the sash strips" 2. 'illie lower ends of these strips rest on the windowvsil'l while the upper end terminates alshort dis: tance below the bottom of the upper sash.

These strips have therethroughcholesi', said holes being preferably four in number and equally spaced from the top to the bottom of said strips.

The guard rods 8 are suitably threaded on their ends, as shown at 9, to receiyethe binding nuts 10. These nuts are intern .ll-y threaded as shown at 11 to receive the rods 8 and also have on their ends heads 12 which fit into the holes 7 in the strip 6. The body of each nut 10 is shouldered as shown at 13 for the purpose of engaging the strip 6 and forcing said strip into posi tion in the easement at the same time tightening the rods between the two nuts. In

order to readily turn these nuts into position, a portion of the surface shown at 15, has been knurled.

The manner of assembling a guard with:

in a window, assuming the lower sash to be raised as shown in Figure 2, is as follows. The strips 66 are placed within the lower portion of the upper sash guideways a" so that the bottoms of the same rest on the window sill. Each rod 8. which has been previously screwed within its nuts to the limit is held in horizontal position so that the head of each nut is adjacent a hole 7 in strip 6. The nuts are then screwed outwardly on the rod permitting the heads 12 to enter said holes 7 in strips 6. When the nuts are screwed outwardly on the rod a definite distance, the shoulders 13 of said nuts will en age the strips around the holes therein and rorce said strips tightly against the casement, at the same time holdingsaid of same, as

rod rigidly between the strips. The same operation of engaging the rods through the medium of the nuts is continued until all of said. rods are in the position shown'in Figure 1. i r

It should be understood that when the nuts are screwed inward on therods, as

' of said rod and nuts will be less than the distance between the strips when said strips are in position in the easement.

While these rods are made strong enough to resist ordinary pressure brought against them in case of accident, they can be readily removed in case of fire or emergency by seizing the rod in the middle and pulling same so that it will be buckled andthen quickly removed from engagement with the strips. 1

It will be observed that the guard, after being secured to the easement will in no manner interfere with the movement of the lower sash in view of the factthat the said guard is placed within the lower portion of the guideway of the, upper sash.

In Figure 6, a modification is shown wherein the nut 20 has a threaded opening 21 extending entirely therethrough. This nut has a head portion 22 which fits within a, hole 7 of strip 6 and is also provided with a shoulder 23 which abuts the strip to firmly hold the rod in place when the nut is tightly adjusted against said strip. Instead of using a knurled nut as shown in Figure 4, a win nut 25 is employed for adjusting said ro to proper position. The

when

rods are of a length to permit them,

to be the nut is screwed fully back thereon, placed between the strips 6.

Of course, it should be understood that changes can be made in the construction and application of this guard without departing from the spirit of the invention.

A guard for windows, comprising members having holes therein and adapted to fit within the sash guideways of the casement, guard rods-shorter than the distance between said members when said members are within the sash guideways, flanged nuts on the ends of said rods capable of being screwed onto said rods so that the distance between the outer ends of the heads of said nuts on the rods will be shorter than the istance between the members when said members are in position in the easement, and portions on the outer end of said nuts adapted to fit within the holes in said members when the nuts are screwed outward on said guard rods permitting the flanges on said nuts to engage the members and hold said rods and members firmly in desired position.
