IMPROVEMENT IN WINDOW-GUARDS.

The Schedule referred to ln these Letters Patent and making part of the same.

To all whom it may concerns;

Figure l is a view of the window from the inside ot" the building when the sash is lowered. In this figure rny invention does not appear, except iu dotted lines. The window `when closed may present its 4ordinary appearance, both from the inside and out` side.

Figure 2 `is a central Vertical section through the window with the sashclosed, or, in other words, it corresponds withzthe view in iig. l.A

Figure 3 is a horizontal section.

The remaining figures show the inventioniu'nse. In this the window-sash is raised, andthe guard, which was'bef'ore concealed and out oi' the way, becomes'- now eiicient to perform` its useful function of guarding the open portion of the window:

Figure 5 represents a portion of the wiudowsash and frame with my guard on a larger scale.

Similar letters of reference indicate corresponding figures in all the parts.

A is the window-frame and eouu'e'ct'ed parts, forming portions ofthe lixed material of the building;

B is the lower sash; and

O, the upper sash oi the window. They are supported by cords and weights, and all parts so far as are yet described, may he of suitable or ordinary construction. I

A. series of parallel or upright bars, m rn, which may be by preference hollow tubes 0i' iron, tinned, or 'otherrvise protected against oxidation, is connected at the top'to the cross-bar llLwhioh is let into the lower edge ot 'the sash B, and is secured so as to be moved.

up and down therewith, the nprights fm. playing through holes in the bottom of the window-case. The'space thus made for the bars in ruust continue down to a' sucient'depth to allow the sash to sink to its seat.

fI make the holesin the lower part of the windowsash alittle Vlarger than the. bars nl., and drive in or otherwise x therein thimbles D, which, holding their upper edges above the upper surface, prevent the eutrance` of water, except the Very small quantity which may strike the bars and run down. Oi' course, in wet weather, the window will be closed.

I can make the vcoarnings thus provided byV the thimhles D of very little height, as represented, and

they will, inv such oase, involve no serious Ydisadvantage, by holding the window-sash B a little up from its ordinary sent, but I prefer to 'provide a space for this coaming or thirnble to extend up into the sash; this kmay be done by recessing M around the junction of the rods m, or, as I prefer in practice, the entire bar M may be let'up into the window-sash to a sull iicieut height, as represented in fig. 5.

I -hu-ve represented the bar M as secured by or-v dinary wood-screws; these allow of convenient removal by an ordinary screw-driver to allowfor cleaning the window, or for repairs.

I propose to substitute any ordinary or suitable means for detaching this bar M, andgconsequently for lowering the window-guard, so that it will he out of the way. One or more spring clips, bolts, keys, or.

vthe like may serve. I would prefer a verystroug and efoient fastening for the lower stories, as a better safeguard against the entrance of' unauthorized 'parties from without, and a quickly detachable fastening may be preferable foi-the windows i'or the other floors.

The bnrsm may be attached-to the bar M by welding, casting in one piece, blazing with hard solder, or any other approved manner. I prefer for some rea sous tapping the pipes 'nt into the har M .and then brazing. l

Thebenefit of my invention cannot he realized by adopting otherlforms than the parallel hars m here described. Any grating, netting, or the like allowed to sink through the base of the window-frame, or 'even to be folded, rolled, or otherwise compacted on the surface thereon, so long as it is attached to thesash B, and caused to rise and sink therewith, would be a self-removing guard, hut such could not rise and sink through small and close-fitted holes like mine.A

I prefer the construction representedwith the thimbles D, or their equivalents to guard the several holes as represented.

I propose, where the masonry will noty allow the bars to sink to the proper depth, to construct them in two or more lengt-hs, united in the manner known as telescopic tubes.

I claim as new, and as my inventionl. rIhe'within-desoribed window-guard, composed of parallel bars in attached to the window-sash and rising andsinking through thecorresponding series of close-fitting holes when the window is opened and closed, substantially as and for the purposes herein set'forth.

2. The thrnbles or coamings D, arranged relatively to the parallel bars m, and to the window-cas ing and movable sash therein, substantially in the manner and for the purposes herein set forth.

In testimony whereof I have hereunto set my naine in presence of two subscribing witnesses.

Witnesses: -W. K. THOMAS.
