WINDOW ATTACHMENT.

Application filed October 3, 19-22. Serial NO. 592,169.

To (ZZZ who/ii it may concern:

Be it known that we, ROBERT E. Gnovns and ORA B. GARNAI-IAN, citizens of the United States, residing at Clarksburg, in the county of Harrison and State of est Virginiay'have invented a certain new and useful In'iprovement in Window Attachments, of which the following is a full, clear, and exact description.

The object of this invention is to provide a portable window attachment in the form oi a cabinet or box. for use in containing foods, and which may be arranged in a window so as to project either out-side of the building or inside of the room, and which may be converted into a students natural light study or drawing table, or a window cleaning platform, or painters stand, or a flower or plant table or stand, or a glass equipped hot-house for starting and maturing early plants, the device being capable of being placed securely in position in a window without the use of screws or nails and without interfering with the opening and closing ot' the window.

The invention consists of a portable stand having a bottom provided with sliding cleats adapted to engage a window frame and to be clamped therein in such engagement so as to be secure against accidental displacement, and a detachable cover, as we will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several. views of which like parts are similarly designated, Figure 1 is a vertical section illustrating the device projecting outside of the building. Fig. 2 is a similar view showing the device arranged inside of a room and without thecover. Fig. 3 is a perspective view or the stand detached. Fig. i is a vertical section through the connecting means. Fig. 5 is an inside elevation of the connecting means taken on line S -So t 4. Fig. 6 is a horizontal section taken substantially in the line 6+6, Fig. 1. Fig. 7 is a perspective view 'of the closed cover. Fig. 8 is a per spective'vie'w of theglaz ed cover. Fig. 9 is a perspective view of shelf. 10 is a partial cross section and sectional elevation on theline 10 10 of Fig. 1.

The bottom or platform 1 is made of suitable material and of proper depth for the purposes of the device and of the width to fit within the window opening. On opposite.

sides of this bottom are erected posts 2 preterably braced by angle irons or brackets 23 which are secured to the bottom and the posts by screws or bolts 4. The fronts of these posts are provided with the transverse grooves 5, and they are pierced from front to rear with holes 6, shown more especially in F 4 and 6, to receive bolts 7 having thu1hb-nuts 8 which take their bearings against the brackets 3. The sides of the posts and brackets are provided with the L- shaped grooves 9.

The connecting means include sliding cleats 10, one for each post, and these cleats are preferably made of two parallel pieces 11 and 1.2, theouter pieces 11 being provided with transverse grooves 18 to receive the heads 14. of the bolts 7 and the inside pieces 12 provided with transverse slots 15 aligned with the grooves 13 so that these cleats may be moved sidewise in order to adjust them to the grooves 16 in the window frames in which the window sashes are movable up and down. By tightening the nuts 8 on. the bolts 7 these cleats may be clamped to the posts in any given lateral adjustment with relation to the posts. so that one of the devices equipped with them may be used in windows of diiterent widths within the maximum lateral extension of these cleats beyond the bottom 1. The inner pieces of.

the cleats are provided with

transverse batv tens

17 and 18 to cooperate with the transverse grooves 5 in the posts 2 to insure parallel motion. The outer pieces 11. of the cleats are longer at both endsthan the inner pieces 12 so as to overlap the edge of the bottom 1 at the bottom and to overlap at the top the cover hereinafter described. The pieces 11 and 12 may be united in any suit-' able way so as to make them practically solid and we have herein shown them united by means of screw bolts 19, Fig. 4, engag ing the battens 17. a v In eur scheme of a convertible device which can be secured in a window without the use of screws or nails. it is. important that the operative parts be consolidated and minimized; In our invention there are no exposed slotsin the cleat adjustment fea= ture's ionl-yOnbolt on each side is necessary; the adjustable eleats are whollyv separate from the cover; there is no strain .plac edon the cover by the cleats and bolt-s the heads of the bolts are concealed; the bolts may not fall out of place when loosened or their nuts detached; making the cleats in two parts permits the concealing" of the bolt heads and the permanent attachment of the bolts and cleats. and the use of the posts to support the cleats and take the strains admits of a simple and readily operable lateral adjust ment of the cleats into and out of the window frame grooves. These and other advantages are designedly incident to the construction referred to.

The structure having" the features so far described may be used for a variety of purposes, as for example, as a platform on which a window washer or a painter may sit or stand, or it may be arranged so as to project into the room, as shown in Fig. 2. in order to form a table for a student or other person requiring strong natural light for working purposes, but a primary object. of the invention is to utilize the device for keeping or protecting food, and for this purpose a cover 20 may be used, having a closed end 21, opposite sides 22, and closed top 23. A shelf 24 may be proviued also and supported on the sides of the cover, or any number of such shelves may be used.

, The sides 22 of the cover are provided with lugs 25, Figs. 1. 7, 8 and 10, which are adapted to enter the grooves 9 by horizontal movement and then dropped down into the bottom of these grooves to lock the cover on to the posts and over the bottom 1. To provide for the

battens

17 and 18 the front edges of the sides of the cover are notched at and to provide for the upper ends of the cleats, the cover may be notched as at 27 at both ends.

A cover such as just described is useful when the device is to be employed for the keeping of food; but when the device is to be used as a hot-house or for sun-cooking purposes, said cover may be replaced by a glazed cover, such as shown in Fig. 8, and d. ,rnated 28, such a cover being made up of suitable wooden or other framing 2:, provided at top, end and sides with panes of glass or other transparent or translucent material 80.

As will he noticed in Figsi and 8, the tops of the covers have an overhang extending; toward the front, and this for the .purpose of c vering in the cleats and to make as close contact with the glazed window sash 31 as possible. lVhen the window sash 31 is shut down in front of the device, as illustrated in Fig. 1, it serves as a substitute for a door or other closure for the device, and thus dispenses with the necessity for a separate closure for the device. l-Vhen the device is placed on the inside of a room as shown 111mg. 2, the bottoinsash may be raised and t-lietop sash lowered in order to close the window-opening.

lt 11 e listed y ompa i n a es- 1 and 2, that when the device is to be used on the outside, the cleats are arranged in the grooves of the upper sash, while when the device is used inside the room, its cleats are arranged in the grooves of the lower sash.

In addition to the uses described for our invention, it may be added that it may afford supports for a board or other platform for workmen engaged in work on the outside of the house, thus serving as a sort of scaffold platform or as an element of scaffolding.

When the cover is engaged with the grooves 9 in the posts 2 as already described, its side and end edges contact with the bottom 1 to make a sufficiently tight joint to exclude flies and other insects. and its top rate upon the upper ends of the posts and is in contact with the upper ends of the cleats to make similar tight joints at these points. After the cover is in' place and its lugs 25 are settled in the bottoms of the grooves 9, then the nuts 8 are turned up so as todraw the cleats tight against the posts and in proper position in the sash grooves of the window if nine, and so the device is held in position in the window against the possibility of accidental dispiz'rcement, and without the use of screws or nails fastening means. This dispe ing with the use of screws, nails or other similar fastening devices avoids marring the window frame, and not only so, but provides for the ready portability of the device. Obviously the device may be put in position and with equal facility removed by the proper manipulation of the cleats.

The invention is susceptible of a variety of alterations in structure from what has been described, and also in changes in details so long as the principle of the iuveu tion as herein explained and hereinafter claimed present.
