WINDOW-SASH.

SPECIFICATION forming part of Letters Patent N o. 554,07 5, dated February 4, 1896.

Applidfild October 2, 1895. Serial No. 564,421. (No model.)

T0 all whom t may concern.-

Be it known that I, CHARLES C. MILLER, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved IVindow-Sash, of which the following is a full, clear, and exact description.

This invention relates to window-sash.

A window-sash as ordinarily constructed and arranged within a casing is apt to shrink or swell with the atmospheric changes. Vhen the sash is contracted it will rattle in the casing, and when expanded itis difficult to raise.

The object of my invention is to obviate these objections.

My invention consists in providing a yielding attachment for the side rail or rails of a sash, and to which the weight cord is attached.

The invention further consists in the construction and novel arrangement of parts, as will hereinafter appear and be particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of a sash embodying my invention. Fig. 2 isa section on the line 2 2 of Fig. l. Fig. 3 is a longitudinal section of a yielding attachment. Fig. 4 is a front view of a portion thereof, and Fig. 5 is an end view.

Referring to the drawings, A designates the lower sash, A the upper sash, and A2 the window-casing. I have here shown a yielding attachment for each side rail of the sash; but it is to be understood that practically the same result will be attained by attaching it to one side rail only. rlhe yielding attachment comprises a metal boxing B, open at its front and adapted to slidebetween the stopbead a and parting-bead c of the casing. A metal shell Bis secured to the side rail of the sash by means of screws. This shell B' is designed to iit snugly, yet movably, within the boxing B. As a means to provide a good hold for the screws employed for securing the shell to the sash-rail, I employ a metal reinvention.

force-strip b, placed'within the shell and having tapped holes in which the screws engage.

Springs B2 are attached to the reinforcestrip b, and their free ends bear against the inner surface of the boxing B, as shown in the drawings. I have here shown three springs; but more or less may be employed withoutA departing from the spirit of my in- A guide pin or screw b" projects from the lower end wall of the shell through a guide-slot h2 in the lower end wall of the boxing, and a sash-cord b3 is attached to the upper end wall of the shell and extends through a slot-opening b4 in the upper end wall of the boxing, over a pulley which is here shown as located on top of the casing A2.

It will be observed that the shells B for a sash extend slightly beyond the surface of the stop-bead and parting-bead, and that the central fastening-screws a2 serve as pivots on which the sash may be turned after removing the other screws, thus making it convenient to clean the outer side of a glass by a person standing within a room. y

By the construction shown and described it is clear that a sash may be easily removed, when desired, without Iirst removing a stopbead, as is necessary with sash of the ordinary construction.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination with a window-sash, of a yielding extension for a side rail thereof, comprising a metal boxing open at its front and adapted to slide in a window-casing, a metal shell secured to the side rail of the sash, a reinforce-strip in the shell, springs secured to said reinforce-strip and bearing against the inner surfaceof the boxing, a pin extended froin the lower end of the shell through a slot in the lower end of the boxing and the said shell having an opening in its upper end wall for the passage of a sash-cord, substantially as specified. Y

2. The combination with a window-sash, of yielding extensions for the side rails thereof, comprising a metal boxing adapted to slide in the window-casing, metal shells secured to the side rails of the sash and having theiil side portions extending into the boxings, the said shells bengextended toward the Center of the Window slightly beyond the stop and parting beads of a easing whereby the sash may be turned on central horizontal pivotal Connections With the shells, leinfoicest1ips in the shells, springs secured to the reinforce-strips and bearing aga-inst the boxings, and a guide- 1 o pin at the lower end of the shells, substantially as specified.
