To all whom t may concern: i

Beit known that I, CHESTER E. Mo- GowAN, a citizen of the United States, residing at Memphis, in the `eountylof Shelby and State of Tennessee', have invented a certainanew and useful Improvementin Metallic `Sash-Bars, of which the following :is a specification. l

My" present invention pertains to an improved metallic sash-bar, 'the construction and advantages of which will be hereinafter set forth in detail. i

The main object of they invention is to produce a strong yet relatively light bar, one simple in form and embodying a minimum number of parts. y

A further object is to prov-idea structure which will ventilate the window and ,likewise drain the same.y

4Ay still further `object is` to"provide` a screen, preferably housed within the bar, to upreventthe ingress of dust and insects through tliewent and drainageopenings-c Another object `is to provide a slide to control the vent openings, whereby they maybe closed when required.

The structure is shown in the annexed drawings, wherein:

lFigure l .is a .sectional vperspective view of a portion of the-bar and window-pane, and of the sill or store-front proper.; and

Figs. 2 to 7, both inclusive, sectional views of different embodiments of the invention.V

Similar reference `numerals will be employed throughout the various figures to indicate similar parts.

The bar maybe saidto comprise two parts; a body portion, formed from a single piece of metal` bent `orotherwise `brought to form, embodying a shelffor supporting the pane, `a back stop or pane-engaging member, and a gutter, combined with a front, paneengaging molding, the body portion being secured directly or indirectly to the window framing or sill, while the front moldingis secured to the main body portion or member, or some member fixed rela-tively to the body member or sill.

Referring first to the construction illustrated in Fig. 1,A 10 denotes the sill and 11 the flooring of the window.` 'ylhe combined backstopand shelf of the bar is formed from a .single piece of comparatively light metal, preferably copper, and consists of a base plate 12, a vertical front `wall 13, a

shelf 14:, and a forwardly-inclined .pane-` clampingmember, bead or back stop proper, 15, the upper edge 16 whereof is turned over and downwardly, clamping between its folds the edge of the `upwardly-extending gutter member' 17. Saidmember 17 extends from the lower forward portion ofthe `perforate gutter member d8, which latter` is turned inwardly from the .back ,wall y19, rising from the base plateA 12. rllhere is thus produced a hollow structure or. bar, consistin'gof a base proper formed by members 12, 13.7and 19, surmounted by a yshelf,.a back stop and a ggutter. Wall `19de preferably formed with an yinwardly-extending bead 20, which not only stiffensxsaid wall but also forms the support for one edge'of a wire gauze screen 21, interposed between the rear wall 19 and the rear `or inner face of the back stop lor member 15..\.Member 18 is provided with a series the front wall at its lower portion is likewise provided with perforationsw23, these two series. providingk for .drainage andventilation, and the screen arresting Vthe lpassage into the store, window of dust and ,insects through the openings 22.

The `glass pane is denoted by 24, and. rests upon blocksoffwood, `leather or other suitable material 25,interposed at interv-als between its loweredge andthe shelfl. y

The face molding may be of any approved type, but preferably will be pro-vided with a clamping lip 26, extending` upwardly land inwardly from the body, denoted asa whole by 27. lin the type illustrated the `face molding is folfnieclavith a horizontal channel 28, adapted to house the heads ofv screws 29, which pass through openings in said` channel, and through alined openings 30. and 3l., provided, respectively, in the vertical walls 13 and 19 of the coinbinedback stop and supportingshelf, and into the flooring A`11, or othercorresponding element. Thelower, forward portion of the moldii'ig `is provided with a series of openings2, to complete the drainage and Ventilating system. 1 As will be noted upon reference to all :the figures, the glass is "held between.` theedges of bead 15 and lip or flange 26, and said members contact with the glassat points orlines remote from the edge thereof. By reason of this arrangement, breakage owing` to pressure brought `abou'tlby expansion due to heat is minimized, whilefat the saine time the of openings 2.2,.and

glass is rmly'held at all times and under all weather conditions.

` The construction is at once strong and simple and is easy of placement.

In Fig. 2 I have shown the same general arrangement but in addition have provided a perforated slide 33, vlocated in the upper rear portion of the back stop or body member, by the manipulation of which slide the openings 22 may be closed. Ventilation is desirable in cold weather, to keep the inside surface of the glass pane as cool as the outside (or approximately so) in order to prevent condensation, but when there is no condensation the slide may be shifted to close the openings and prevent the ingress of air ltherethrough'. When the window is being washed, the slide will be opened to permit the outflow of the water.

Under some conditions it may be desirable to secure the combined back stop and supporting shelf lto the sill instead of tothe window flooring, in which case a construction'or arrangement such as illustrated in Figs. .3, 4 and 5 may be employed. In Fig. 3 the combined shelf and back stop is secured to the sill 10 by'screws 34, lopenings being provided in the shelf for the introduction of the screws. Housed within the body is a channel bar 36, which will likewise have openings 37, and machine screws 38 are passed through the face molding and front wall 13, and into threaded openings in the forward member' of the bar, whereby the parts may be drawn to position. Bar 36, having an extended bearing on wall 13 throughout its length, prevents undue strain being exerted upon the wall and distortion of the'parts. The forward lower edge of the channel bar 36 will preferably be notched, asat 39, for the purpose of drain- `age and ventilation.

In Fig. 4 a somewhat similar construction is illustrated, wherein an inverted T bar 40 is employed and secured to the sill by screws 34. Machine screws 38 take in threaded openings in the vertical member of the bar `and draw the parts to place.

In Fig. 5 the combined back stop and shelf is secured directly to the sill by screws, and the rear wall 19 is provided with a countersunk vrecess 42, adapted to receive nuts 43 into which bolts 44, passing through the face molding and the front wall 13, are screwed. The countersunk recess stiffens the rear wall, the same as the bead 2O in the other constructions.

Under allthe constructions thus far set forth it will be noted that the joint in the combined back stop' and shelf is formed at the junction of the back stop member 15 and the upstanding element or member 17 and this by clamping the upper edge of 17 between the back stop and theoverturned upper edge 16v thereof. This construction produces a stiifening effect in the back stop and gutter, rendering them rigid.

In Fig. 6 I have disclosed a further modiication, wherein the back stop is formed with a rearward, horizontally extending member 50, the rearmost edge whereof is bent or clamped, as at 51, upon and over the upper edge of the rear wall 19a. Said member 50 may be provided with openings 22a, which for the purposes of ventilation and drainage cooperate with the other openings 23 and 32, as in the previous constructions.

Under the constructions disclosed in Figs. 1, 2, 6, and also in Fig. 7, nails as 55 are passed through the front wall 13, the back wall 19 and into the iiooring 11, thereby initially securing the combined back stop and shelf in place. Said nails are so located that they directly underlie the shelf 14 and tend in a measure to prevent the same from sagging under the imposed weight of the plate.

With the construction shown in Fig. 6, the openings for the fastening screws 29 are located at such height that the body of the screw directly underlies the shelf 14 and acts in conjunction with the nails just mentioned to support the shelf against sagging movement due to the weight of the plate.

In Fig. 7 the joint between the edges of the sheet from which the combined back stop and shelf are produced is at the lower forward corner. The horizontallydisposed member 52 of the back stop under this construction may lie in the same plane as the window iiooring, thus producing a smooth, iush and even finish.

Under this construction and also that shown in Fig. 6, the horizontally-disposed member (52 or 50) produces a rigid back stop, which, of course, is present in the other constructions, owing to the imposing of the member 15 upon the member 17, and the clamping of the two together by the overturned edge 16.

Under all the constructions it is to be noted that the back stop presents a line contact with the plate and that at a point suliciently removed from the edge of the plate to prevent breakage thereof. Such line is opposite the line contact effected by the member 26 of the face molding.

It is evident from the foregoing that in so far as the generic invention is concerned it may be varied in detail without departing from the spirit of the invention, and the broader claims are to be construed in light hereof.

It is likewise evident that while the structure may be produced from light material, it is strong and durable; and any tendency for the shelf 14 to sag is counteracted by the back stop member 15 and the gutter elements 17 and 18, to the first of which said member 15 is secured.

Having thus described my invention, what I claim is:

l. In a metallic sash-bar, the combination of a combined shelf and back stop for a plate of glass, with the back stop portion presenting a contact line to the plate removed from the edge of the plate, said combined shelf and back stop being produced from a single piece of met-al brought to form, with the edges thereof secured to each other; a face molding; and means for securing said molding in place with reference to the plate supported by the shelf.

2. In a metallic sash-bar, the combination of a hollow combined base, shelf and back stop produced from a single piece of metal brought to form and having the edges there- -of interlocked; a face molding, said molding and back stop having opposing line contact with the plate of glass supported by the shelf; and means for securing said molding in place with reference to said shelf and back stop.

3. As a new article of manufacture, a combined shelf and back stop for use in metallic sasli-bars, produced from a single sheet of metal bent to form and having its edges interlocked and presenting a hollow base, a shelf thereon, and a back stop extending upwardly and inwardly from the shelf at one side thereof.

L As a new article of manufacture, a combined shelf and back stop for use in metallic sash-bars, produced from a single sheet of metal bent to form and presenting a hollow base, a shelf thereon, and a back-stop extending upwardly from the shelf at one side thereof and inclining toward the opposite edge of the shelf, the proximate edges of the sheet being secured together.
