SAFETY WINDOW-CHAIR.

Specification of Letters Patent.

Application filed September 7, 1912.

Patented July 29, 1913.

Serial No. 719,174.

To all whom it may concern:

Be it known that I, CARL E. BROWN, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented a new and useful Safety VVindow-Chair, of which the following is a specification' The present invention relates to improvements in safety window chairs, the primary object of the invention being the provision of a novel form of chair or seat adapted to be removably attached to a window sill to provide a safe and comfortable seat for the party when cleaning windows, the same being provided with an adjustable back which will assume several positions when acting as a back, and which when not in use may be folded upon the seat.

A further object of the present invention is the provision of a novel arrangement of clamping devices whereby sills of varying widths or relation may be accommodated, thus providing a simple, durable and inexpensive device of this character.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a perspective view of the sill portion of a window with the safety chair in operable relation, a portion being broken away to show the outer sill engaging clamp. Fig. 2 is a perspective view of the chair with the back in its inner most reclining position. Fig. 3 is a side elevation of the chair folded.

Referring to the drawings, the numeral 1 designates the seat member which as shown carries the removable and adjustable outer sill engaging member 2 whose connecting pin or bolt 2 is removably fitted in either one of the apertures a.

The inner sill engaging member 3 is connected to the seat by means of the bolt 4 which fits in any oneof the apertures b and thus with the outer sill engaging member 2 provides an adjustable clamp for connecting the seat to varying widths of sills, the member 3 being provided with the thumb screw 5 for engaging such member to the under side of the inner sill. By this means the seat 1 is rigidly connected to the sill against any accidental displacement so that the outer free end of the seat projected beyond the outer sill will be properly supported and braced to safely accommodate the party cleaning the window.

In order to provide a folding and adjustable back for the outer free end of the seat, the two brackets or arms 7 have theirinner ends hingedly connected to the seat 1 by means of the pins 6, the free ends of'said arms at 8 being pivotally connected to the back 9. The limiting pins 10 are connected to the seat in the path to be engaged by the respective arms 7 when the back 9 is placed in either position as shown in Fig. 1, it there being held at right angles to the extreme outer end 11 of the seat 1, or in an inclined position, as shown in Fig. 2.

When the chair is not in use, the seat 9 is folded to assume the position as shown in Fig. 3, thus making a compact package when moved from one window to another, the complete article being of such small dimensions and weight as to permit it to be readily carried.

To provide for outer sills of different buildings being of diflerent heights in relation to the inner sills and it being essential that member 2 should rest on the outer sill to sustain weight of the person sitting in the chair, member 2 has one end longer than the other and this member being removable and adjustable, two heights can be secured, and in connection with a block two additional heights may be obtained.

What is claimed is:

1. A safety window chair, including a seat member, means for attaching it to a window sill, and a back swingingly connected to the seat member near the outer end thereof for coaction with the extreme end of the seat member or the upper surface within the extreme end to form a braced back for the seat member.

2. A safety window chair, including a seat member, a pair of brackets pivotally connected to the seat near one end thereof, means for limiting the extension of the brackets, and a back member pivotally connected at its sides and within its ends to the free ends of the bracket and disposed for co-active relation with the seat to form a reclining back or a back at right angles to the seat.

3. A safety Window chair, including a seat member, a pair of brackets pivotally connected to the seat at the sides near one end thereof, means for limiting the extension of the brackets, and a back member pivotally connected to the free ends of the bracket, such pivotal point with the back member being at opposite sides above the center line to produce an over-balancing to the back member when the arms are in engagement with the limiting means.

t. A safety Window chair, including a seat board, a pair of right angled arms having their inner ends pivotally connected adjacent to one end of the seat board With their angles for movement toward such end,

pins connected to the seat board at such end and in the path to engage the arms adjacentto their angles and limit the extension of the arms, and a back board piv otally connected in the free ends of the right angled arms, said arms engaging the back boardintermediate of its top and lower edges.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of tWo Witnesses.
