Application filed September 12, 1891- Serial No. 405,526. (No model.)

tion consists in the details of construction set forth in the following specication and claims, and illustrated in the annexed drawings, in which- Figure l is a section along .7c Eig. 3, of the support secured in place. Fig. 2 is a rear View of Fig. 1. Fig. 3 is a plan View of Fig. l.

In the drawings, the letterA indicates a seat or support. An arm B extends from said seat, and a brace C is jointed at D to said arm. Vhen the brace or holder C is swung to a position at a right angle to the arm B, it is arrested in that position by its shoulder or end E striking against the arm. The arm can then he placed on a window-sill F, with the brace or holder C extending down inside the sill, so as to hold the seat A in place.

The arm B slides through the eyes or guides G of the seat and is arrested at the proper point by a peg or Stop H. The arm B 'has a series of holes or perforations I, so that the peg H can be applied at various points to adjust the arm along the seat, as may be required for various widths of sills.

The back K is jointed at L to the seat A, and said back has arms or braces M extending below the seat. lVhen the user leans against the back K, the braces M are forced against the wall or side N of the house, so as to draw the brace o1' holder C firmly against the interior of the window-frame.

The back K is not jointed directly to the seat A, but to brackets O, extending from said By making the pin I-I in form of the wellknown split pin or spring-pin said pin will clamp itself in` the holes I, so as not to fall or come out accidentally; but of course any suitable pin or peg can be employed.
