UNITED STATES PATENT O FICE.

ALGERNON L. WVILKINSON, OF HUNTSVILLE, ASSIGNOR OF ONE-EIGHTH TO JOHN L. RISON, OF MADISOA COUNTY, ALABAMA.

SASH-HOLDER.

FECIFICATION forming part of Letters Patent No. 314,896, dated March 31; 1885.

Application filed October 7,1584.

To all witom it may concern Be itknown that I, ALGERNON L. WILKIN- soN, a citizen of the United States, residing at Huntsville, in the county of Madison and State of Alabama, have invented certain new and useful Improvements in Sash-Adjusters, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it [o appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in sash-holders especially adapted for use in railway and street cars, steamboats, omnibuses, and the like wherein a single window or sash is used; but it is, however, capable of application to windows of dwellinghouses, &c.

The invention has for its object the provision of means whereby the sash may be held at any desired point of elevation, and be practically noiseless and free from rattling when in motion or acted upon by the wind.

To these ends the invention consists in the provison of a window-frame of ordinary construction with spring-pressed strips arranged to bear at right angles to each other upon the sides and ends of the sash, and means for varying the tension with which the strips press upon the sash, and of guide-pins which are adapted to guide the strips in their movement, as hereinafter more fully described, and point- 5 ed out in the claim. 7

In the d awings, Figure 1 is a front elevation of a window framing and sash of a car, steamboat, &c., having but one sash. Fig. 2 is acentral section of a window of a dwellinghouse having two sashes. Fig. 3 is a crosssection on the line m w of Fig. 1. Fig. 4 is a front elevation of the bead with the springpressed strip removed, and showing the window-frame in section. Fig. 5 is a longitudinal section'of a portion of the window-frame. Figs. 6 and 7 are cross and vertical sections, respectively, of the window bead or slat.

Referring to the drawings, in which like letters of reference indicate like parts in all the figures, A designates a window-frame of ordinary and well-known construction, and B a window-sash. The sidepieces of thewindowprovide a bearing for the same.

(No model.)

frame a e provided'with longitudinal recesses a a, in which are placed strips 0 O, which are pressed normally outward in contact with the sash by means of springs b 0, arranged between the inner wall of the frame A and said strips 0, as clearly shown in Figs. 2. and 5.

D designates strips or slats secured by screws or otherwise to the inner sides of the frame A, near its outer front edge, or removed a short distance to the rear thereof, and provided with recesses d d, in which are placed strips E'E, kept in contact with thesides of the sash B by springs d d, secured in the recess of said bead. Each of the strips 0 and E, which, it will be observed, hear at right angles to etch other upon the ends or sides of the sash B, respectively, is provided with short tubes e e, arranged near its upper and lower ends,'and through which pass guide-pins F F, secured to the frame A and slat or head D. The slat D is further provided with ap ertures f, through which project screws 9, se-

cured to the strips E, (see Figs. 6 and 7,)

while the strips 0 are provided with apertures 'h and receive screws 2', secured to the frame A, as shown in Figs. 2 and 5.

I attach importance to the guide-pins F and tubes 6 e, as the pins serve to guide the strips in their movement, and the tubes lessen the friction of the said pins working therein and I also attach importance to the screws 9, as the tension of the-springs can be increased or decreased by simply turning the said screws in or out. It will be observed that the screws also serve to limit the movement of the spring pressed strips. This limiting movement is occasioned by the heads of the screws impinging against the tapering walls of the recessed strips and head.

It is obvious that either coiled or flat springs may be used to force the strips outwardly, both of which forms of spring are herein shown.

The frameis provided with beads I, arranged on the opposite side of the sash to the slat D, against which the sash bears, as is usual, and may be constructed similarly to the slat D, but not necessarily so, inasmuch as the sash I00 is amply supported and prevented from rattling by the strips Gand E, which form essential features of my invention.

The sash may be provided with a button or hook, J, for conveniently raising it, if desired. v

Modifications in the form and proportion of parts may be made without departing from the principle or sacrificing the advantages of the invention, and I would therefore have it understood that I do not limit myself to the precise construction herein shown.

I am aware that it is not broadly new to provide a sash-holder with spring-pressed strips to bear upon the ends of the sash-frame, nor to provide a frame and sash with springpressed strips and catches and notches; but in these devices the sash is subject to a movement at right angles to its vertical movement, thereby occasioning a rattling noise when the sash is elevated which my device overcomes.

It will be understood that when my device car, steamboat, 850., in the form illustrated in with friction-tubes in which said guide-pins are adapted to play, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ALGERNON L. WILKINSON. \Vitnesses:
