J. WARTENBERG WINDOW CHAIR Filed Jan. 5. 1925 Patented Sept. 29, 1925 JOSEPH WARTENBERG, O'F NEWBURGH, NEW YORK.

WINDOW CHAIR.

Application filed January 5, 1925. Serial No. 505.

To all whom it may concern:

Be it known that I, J osErI-I VVAn'rnNBnRo, a citizen of the United States of America, and resident of Newburgh in the county of Orange and State of New York, have invented certain new and useful Improvements in Window Chairs, of which the following is a specification.

This invention relates to improvements in window chair constructions adaptable for use in connection with the cleaning of the outside of windows. The construction consists of the main horizontal frame having a seat adjacent to one end and a back adapted to be folded downwardly into the frame and side members thereof which extend through a window and are each adapted to receive a slidable, vertically arranged clamp thereon for securing it in properrelation with said frame and clamps for securing the construction in position in the window. These clamps are also provided with a frame and foot-support which further tends to add to the stability and usefulness of the construction.

The invention consists further of certain details of construction which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawing, in which like characters of reference are used to designate corresponding parts in the several views,

Figure 1 is a sectional view of a wall showing an end elevation of a window chair in accordance with the present invention in position for use on a window-sill;

Fig. 2 is a front elevation of the same;

Fig. 3 is a plan view of the window chair;

Fig. 1 is an end elevation of the window chair showing it with the parts in partially folded position; and

Fig. 5 is an enlarged detail view.

Referring in detail to the drawings the window chair comprises a pair of horizontal side frame members each designated by the numeral 10. These members are secured in parallel spaced relation by means of an end bar 11 fastened to them in any suitable manner on their upper sides and a similar bar 12 on their lower sides. The frames are further secured intermediate of their length by means of a cross-bar 13 which is adapted, as shown in Fig. 1, to rest on the outer portion of the window sill 14.

The bars 12 and 13, together with the side frame members 10, provide a seat frame to which a suitable seat 15, preferably of leather, is secured. The frame is also provided with a chair back 16 comprising upright members 17, pivoted at 18 to side frames 10, and they are provided with a number of cross slats 19 forming a back. At the upper end of the members 17 an additional strengthening bar 20 is secured for rigidly securingthe members together. A pair of pivotally connected links 21 are pivoted at the upper end of each of the members 17 at 22 and to the respective side frame 10 at 23 to cooperate with the cross bar 11 for holding the chair back 16 in its upright position.

lVhen it is desired to fold the back 16 down between the frames 10, the links 21 are adapted to swing together on their pivot 24 as shown in Fig. 4.- and permit the chair back to fold downwardly.

In order to securely support the window chair in a window, the frame members 10 are provided with downwardly extending projections 25 secured on the outer sides of the frame 10 alongside the cross bars 1.3 and adapted to rest against the outside edge of the window sill. These projections are further secured by angle braces 26 which are connected with their lower ends and with the side frames 10. On the inner ends of the side frames .10 which project through the window, are slidingly mounted clamp structures 27. These clamps have thumb screws 28 which are adapted to fasten them in the desired position on the frames 10 so that their lower projecting portions 29 will extend inside of the inner edge of the window sill 14: in the manner shown in Figs. 1 and 2. This latter projection portion 29 is provided with a screw 30, the inner end 31 is adapted to engage the wall below the sill 14 and may be tightened by handle 32 on the outer end thereof.

To the inner sides of the clamps 27 arev secured supporting bars 33 and to the lower end of these bars is a foot-rest 34. This foot-rest, as indicated in Fig. 4, may be secured at the desired height to suit the individual using the chair in any suitable manner (not shown).

As a means for further securing the window chair in position an adjustable brace is pivotally secured at 36 to the outer side of one of the side frames 10. This brace comprises a pair of bars 37 and 38 as best shown in Fig. 5. To the outer end of bar 37 is fastened a guicle member 39 through which the bar 38 passes and over both of these bars 37 and 38 is secured, a clamp 40 which may be tightened by means of a nut 41 on a screw 4L2 forholding the bars to the desired length The outer eiid of bar 37 is offset as shown at 42 providing an engaging member which is adapted to engage the window frame guideway, as indicated in Figs. 1 and 3.

In using the window chair, the frames 10 are positioned as shown in the various figures of the drawing and the clamps 27 are.

placed in proper adjusted positions and secured to the frames 10. The screws 30 are tightened against the wall and the brace 35 is positioned as indicated. In case the chair is used on a wider window-sill, the clamps 27 of course are adjusted as required and the brace 35 is adjusted to the proper length in order that the member 42 will properly engage the window casing.

I claim:

1. A window chair comprising a seat having two frame members secured to the upper side portions of the seat and extending forwardly thereof downwardly projecting means on the under side of said frame, clamping meansvadjustably secured to said frame members for co-operating with the said first mentioned means for securing the cliair in a window a longitudinal bracket pivoted to the innermost end of one of said side frame members, and an offset projection on the free end of said bracket adapted to engage a guide way of the window frame for further securing the chair in the window. I i

2. A window chair comprising a seat having extending side frame members, a downwardly extending projection under the seat for engaging the outside wall of a window,
