WINDOW FRAME AND -SASH.

SPECIFICATION forming part of Letters Patent No. 511,409, dated December 26, 1893.

Application filed May 22,1893. Serial No. 475,038. (No model.

T0 at whom it may concern.-

Be it known that I, AUGUSTUS H. COLE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and use-' ful Improvement in Window Frames and Sashes, of which the following is a specifica tion.

This invention relates particularly to window frames and sashes in railway cars and carriages, and it consists in the novel con struction and combination of parts hereinafter described, whereby rattling and vibration are prevented, and the general construction improved.

In the accompanying drawings, in which similar letters of reference indicate like parts,-Figure l is a front elevation, looking from the inside, of a double sash window frame and sash embodying my invention, portions being represented as broken out to illustrate the improvement. Fig. 2 is a central transverse vertical section of the same, a portion of one of the stop-beads being repreented as broken out. Fig. 3 is a horizontal section on line at, Fig. 2. Fig. 4 is an enlarged section taken on the same line as that shown in Fig. 2.

A represents the sill, B the lintel, O D the upper and lower sashes respectively, E the outer walls of the casings or jambs, and F F the inner and outer stop-beads respectively.

H is an upright or post set vertically within the jamb between the rear stop-bead F and the outer wall E at the rear of the sashes. The front inner corner of this upright is removed to receive the edge of the upper sash O, as shown in Fig. 3.

I is an upright set vertically between the front stop-bead F and the wall E in front of the sashes, but not extending far enough rearward to come in contact with either sash.

The lower sash D extends between the upper sash and the rear edge of the front stopbead F, as shown in Fig. 3, and almost to the outer Wall E. There is, hence, quite a space between the run of the lower sash and the upright I. See Figs. 2, 3, and 4. Within this space are two or more free cylindrical rolls K made of rubber or other analogous elastic substance or composition. These rolls are set with their ends toward the bead F and easing, substantially as set forth.

wall E, and their diameter being normally somewhat greater than the distance between the upright I and the sash D, they are contracted somewhat in their present position by being between said upright and sash, and hence operate to press the lower sash closely back against the rear stop-bead F and the upper sash. The rolls, of which there are shown in the drawings three on a side, rest when at their lowest points on ledges or supports L L L, and when the lower sash D is raised they roll up between it and the upright I, offering practically no resistance to the movement of the sash.

In order to prevent the rolls from falling out, a thin vertical bead or strip e is secured to tillie wall E opposite the edge of the lower sas The upright I is made in two parts, joining, preferably diagonally, at I, as shown in Fig. 2, in order that the sash D may be removed by slipping out the lower section of the upright.

Any suitable contrivances may be applied to the lower sash, whereby it may be lifted and locked, it not being deemed necessary to illustrate such in the drawings.

In order to prevent dust from settling in the lower ends of the spaces beneath the extended edges of the lower sash, the sill is built up on an incline at a (Fig. 1), and the lower sash is made at its lower corners D of corresponding shape. This incline tends to cause the dust to slip out of the space, which is necessarily deep for the purpose of accommodating the rolls and the extended edges of the sash.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a window frame and sash, the combination of the frame or casing provided with.

an internal vertical chamber or space extending in front of the sash, the sash extending into the rear portion of said space, and afree roll of rubber or analogous elastic material within said space and pressed betweenthe front surface of said sash and theframe or 2. The herein described window frame and sash, comprising the jambs consisting of the outer walls E, rear and front uprights H I,

rear and front stop-beads F F, upper sash sill provided with the inclined or beveled extending into a suitable recess in the corner blocks a within said spaces and inclining of the rear upright H, lower sash extending down toward the window, and the lower sash into a vertical chamber or space between the having its lower corners D beveled to corre- I 5 5 rear and front uprights, and free rolls K of spend with said blocks, substantially as set rubber or analogous material pressed between forth.

the lower sash and the front upright and free to roll as the sash is moved in the frame, sub 7 AUGUSTUS COLE stantially as set forth. Witnesses: I0 3. The combination of the jambs provided HENRY W. WILLIAMS,

with the vertical inner spaces described, the J. M. HARTNETT.
