WINDOW-CHAIR.

SPECIFICATION forming part of Letters Patent No. 697,182, dated April 8, 1902.

Application filed May 18,1901.

T0 (@ZZ zuhmn it may concern: 7

Be it known that I, JOHN F. STEOKENREITER, 1 of Chicago, in the county of Cook and State of 3 Illinois, have invented certain new and useful Improvements in VVindow-Ohairs; and I do hereby declare that'the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to an improved portable window chair or platform of that class which is adapted to be detachably connected with the frame-sills of a windowin such manner as to safely support a person thereon while washing the window or while doing other work which requires a person to pass upon the outside of a window.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of awindoW-chair embodying my invention and showing also parts of the Window-frame to which it is attached. Fig. 2 is a vertical section on line 1 2 of Fig. 1. Fig. 3 is a detail plan view of the means for detachably connecting the window-chair with the windowsill. Fig. dis a section on line 3 4: of Fig. 3. Fig. 5 is an elevation of the looped fixture constituting part of said attaching means. Fig. 6 illustrates a bracket attached to the under side of the chair and a screw-threaded stud or jack which is employed for adjusting the chair to the outside sill.

As shown in said drawings, the chair consists principally of a seat board or platform A, which is hollowed at its center, as indicated at a, to suitably fashion the same for a seat and at the same time to lighten the chair. Said chair is desirably provided with a rail ing A, extending around back of the same and supported partly upon the upper ends of vertical standards A Said standards are curved at the lower end, as shown, to provide ample space for the clothing of the person using the chair. The chair is supported on the window-frame sill 1 and outside sill 2 by the following devices:

B B designate two horizontal bars which are attached to the under side of said chair by means of bolts or the like and are detach- Serial No. 60,822. (No model.)

ably connected at their forward ends to parts connected with the window-sill 1. Desirably said bars are set into downwardly-opening grooves in the chair, so as to be flush with the bottom of said chair. Said bars are desirably extended across the principal part of the width of the chair, so as to thereby strengthen the seat or platform and prevent the same from warping.

G designates a bracket attached to and depending. from the lower side of the chair and provided with arms 0 c, by which said bracket is connected with the chair, screws or like fastening devices being for this purpose employed. Said bracket is provided between its ends with a substantially vertical opening which receives a screw-threaded stud or jack D, which passes upwardly through said opening and is supported at its lower end on the outside sill of the window-frame. Said stud D is provided at its lower end with a flange or head (1 to afiord an ample bearing therefor, and desirably the lower end of said head is faced with a disk D, of suitable yielding material-such as leather, rubber, or the like-the purpose of said yielding disk being to prevent defacement of the outside sill and to enable the parts to adjust themselves to sills of varying pitches.

The means for detachably connecting the forward ends of the bars 13 with the-windowsill are made as follows:

E E designate metal loops which are provided with flanged bases E, which latter are apertured to receive screws by which the loops are fastened to the window-sill. Said loops E may be made of any desired shape, and the cross-sectional form of the supportingbars B will be made to correspond with the shape of the loops. The flanged bases E of said loops are inclined to correspondwith the general inclination or pitch of the window-sill, as clearly shownin Figs. 2 and 4, so that when the loop is attached to the sill the loop proper will assume a generally vertical position thereon. The extremities of said supporting bars 13 are provided with upturned or hooked portions B, which pass through the loops E, and when said bars assume a horizontal position, as shown in Fig.- 4, the hooked end portions of the bars ongage the loops in such manner as to prevent the bars and the chair connected therewith being moved outwardly so long as said chair and bars remain in a horizontal position. Said bars are provided inside said hooked end portions with inwardly-facing shoulders Z), which are adapted to engage the outer faces of said loops when the bars are in their horizontal positions, thereby preventing the bars movinginwardly. For this purpose said bars in their principal parts are made of greater width than the loops E, and the extremities thereof, which pass through the loops, are reduced in width, thereby forming the inwardly-facing shoulders I). With this construction it will be seen that when the bars and chair assume a horizontal position said bars are locked from longitudinal movement by engagement of the upturned or hooked end portions B with the inner faces of the loops and of the shoulders I) with the outer faces thereof.

When the window-chair is to be placed in position, said chair and the bars 13 are made to assume a substantially vertical position, which permits the hooked ends of the bars B to pass into and through the loops F. When said hooked ends of the bars have been inserted into the loops, the chair is swung downwardly, the loops E acting as a hingefor this movement, until the chair is brought to a substantially horizontal position, the contact of the jack or stud D with the outside sill limiting the downward movement ofthe chair. When the chair has been brought to a horizontal position with the jack or stud D resting on the outside sill in the manner shown in Fig. 2, said parts are locked securely to the outside and window sills and cannot be detached therefrom until the chair is swung upwardly into a substantially vertical position. When the chair is to be detached from the window-frame, it is swung upwardly to an approximately vertical position, when a slight outward movement is suflicient to release the hooked ends of the bars B from the loops. The parts of the bars which engage said loops are made of slightly-less vertical thickness than the width of the loops, as shown in Fig. .4, thereby permitting the chair to be adjusted (to varying pitches of the outside sill by vertical adjustment of the stud or jack D. The stud D is threaded, so as to turn freely in the bracket 0, thereby enabling this part of the device to be adjusted by hand, and in order to secure the necessary strength to this part the threaded aperture in the bracket 0 is made somewhat longer than will ordinarily be required for a given-sized stud. The attaching-loops E are located opposite the parting-strip 3 of the Window-frame, so that said loops do not interfere with the free movement or closing of the window-sashes. The

stud orjack D is adapted to be supported on the outside sill near the outer margin thereof, so as to enable the seat to be made large enough to give sufficient room outside of the window to permit a person using the same to have all the space required for washing the Window or for doing other work required.

' The mechanism herein shown may be advantageously employed in a window-platform construction made the full width of the window, and in this instance two or more jacks or studs D may be employed and more than two bars B may be used:

The device shown is extremely simple in its construction and may be made of ample strength andat the same time sufficientlylight to enable the same to be handled by persons accustomed to washing windows and do like work about a house.' Moreover, the attaching means shown are such as to effectually prevent displacement of the chair when in its operative position, and thereby reduces to a minimum danger of accidents arising from the imperfect operation of the interlocking parts.

I claim as my invention- 1. A window-chair comprising a solid horizontal seat or platform, bars attached to the lower side of said seat and extending from front to rear thereof for the purpose of reinforcing said seat, the extremities of which bars extend forwardly beyond the seat and are adapted to be detachably connected with fixtures on the window-frame, brackets detachably secured to the under side of the seat, one at 62.011 side thereof, each of said brackets being provided with arms by which it is attached to said seat and with a part having a vertical screw-threaded opening, and a screw-threaded stud or jack extending upwardly into said opening and provided at its lower end with a head or flange which is adapted to be supported on the outside sill of the window-frame, said studs or jacks be ing located entirely below the seat and vertically adjustable in said brackets from below the seat.

2. A window-chair comprising a solid horizontal single-piece seat or platform, bars attached to the lower side of said seat and extending from front to rear thereof for the purpose of reinforcing the seat, the extremities of which bars extend forwardly beyond the seat and are adapted to be detachably connected with fixtures on the window-frame, a rail rising from said seat, vertical standards extending between said rail and seat, said standards being curved outwardly at their lower ends, brackets detachably secured to the under side of the seat, one at each side thereof, each of said brackets being provided with arms by which it is attached to said seat and with a part having a vertical screwthreaded opening located a distance below the seat, and a screw-threaded stud or jack extending upwardly into said opening and provided at its lower end with a head or flange which is adapted to be supported on the outside sill of the window-frame, said studs or jacks being verticallyadj ustablein said brackets from below the seat and located entirely below the seat, and the screw-threaded portions of the brackets being located a sufiieient distance from the seat to permit the ends of the screws to extend between the same and the seat in the adjustment of the screws.

3. A window-chair comprising a solid single-piece horizonal seat or platform, laterallyseparated bars attached to the lower side of said seat and extending from front to rear thereof, said bars being contained in downwardly-opening grooves in said seat and the extremities of which bars extend forwardly beyond the seat and are adapted to be detachably connected with fixtures in the window-frame, brackets detachably secured to the under side of the seat, one at each side thereof, each of said brackets being provided with a vertical screw-threaded opening, a screw-threaded stud or jack extending up- JOHN F.
