SPECIFICATION forming part of Letters Patent No. 299,217, dated May 27, 1884. Application filed February 16, I884. (No model.)

To ctZZ whom it may concern:

Be, it known that I, Gnonen E. GORHAM, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Friction Devices for WVindow-Sashes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My improvement relates to means for in ducing frictional contact between the upper and lower sashes of a window, to cause them, when closed, to be in such close proximity as to prevent the ingress of air from without, thus dispensing with the use of listing, and also effectually preventing rattling of the sashes at whatever position they may be brought.

To these ends the invention consists in the attachment to the sash and frame of such de vices as will be hereinafter distinctly described, and pointed out in the claims.

Reference being bad to the annexed drawings, Figure 1 represents an outer vertical elevation of the two sashes, embodying in connection therewith the employment of my im- Fig. 2 is a vertical sectional view thereof on the line 3 y." Figs. 3 and 4 are inner and outer vertical elevations, respect ively, of a window sash and frame, in which is shown the employment of a substantial modification of the devices shown in' the preceding figures. Fig. 5 is an enlarged view in perspective of the modification, showing a portion of the window-sash.

Referring to the several parts by letter, and in connection with Figs. 1 and 2 of the drawings, A represents the upper sash, having attached to the outer face of the stiles the main portion of my improved device.

13 represents the lower sash, against which the said upper sash is caused to be pressed by the action of the device.

C designates the window-frame, in which the sashes move.

The devices for producing sufficient frictional contact between the sashes for acoomplishment of the above-described objects consist of spring-strips a, which are preferably secured to the outside of the stiles of the upper sash and the inside of the stiles of the lower one, in such manner as to bring a bulging end near or on a line with the lower beveled cross-piece of the upper sash and the upper beveled cross-piece of the lower oneor, in other words, the points of juncture of the two sashes when closed-4n order that the required pressure will always be maintained at this point.

It will be observed that the springs are bulged outward at each end, which produces a depression or concave in the direction of their length. While in this shape they are tempered to give them the proper tension and resilient effect.

Projecting outward from the frame across the face of the stiles are pins, 2), which may be provided with loose] y-turnin g rollers, as shown in Figs. 1 and 2; but I prefer simply employing pins. These are arranged on the frame in two series, (the one for the upper sash being without, while the one for the lower sash is within,) so as to permit the bulges of the springs to be engaged therewith at varying heights, and one of the series on the outside and one of the inner series are located at a j point beneath and just past the lower bulge of the upper spring and the upper bulge of the lower spring, respectively, against which they bear, and as a result the beveled portions of the sashes are firmly pressed together. In addition to a force being exerted in a direct line transverse to the sashes, these lower and upper rollers of the series, by virtue of their location with respect to the springs, tend to exert forces perpendicular to the first, and thus is the support of the upper sash aided, and the counterpart or correspondingly-beveled cross-pieces of the sashes made to tightly abut.

In Figs. 3 and 4 I have shown a wire spring for accomplishment of the above ends, which is provided at about the center of its length with a semicircular bend, f, and at a suitable distance from each side of such bend their ends branch off at an acute angle. Thus is given a bulge at each angle where the ends branch, the same as in the above-described instance. When this spring is secured to the sash-stiles, I propose to drive in a small staple, 5/, over the semicircular bend, until the spring is slightly depressed or drawn in toward the it to allow a yielding action and at the sametime to prevent lateral bending. This wire spring is of substantially the same generic shape as the flat spring first described. My reason for forming it with the semicircular bend and employing a staple in connection therewith is that, by so doing, I obtain a sufficient tension without having to temper it after its formation, as is frequently necessary in the first form. The springs are preferably secured to the outside of the stiles of the upper sash and the inside of the stiles,of the lower one. Two ormore can be used on each stileone above the other-in which case the number of pins on the frame would be less; or by increasing the number of pins 3. single spring on each stile will be found sufficient.

.From the above it will be seen that thesashes can be brought to any point for the purpose of ventilation, the devices always maintaining their efficacy as anti-rattlers by pressing the sashes against the parting-strips, while the sashes, when closed, are firmly pressed together, thus dispensing with the employment of listing.

The sashes can be opened to the desired extent and allowed to rest on some one of the pins, which will prevent their falling.

1 Having thus described my invention, what I claim, and desire to secure by Letters Patrnt, .1s

1. In devices for producing frictionbetween the meeting-rails ofwindow-sashes when closed and between the parting-strips and sashes when open, the combination of the springs a, having upper and lower bulges, and secured at their outer ends to the stiles, as described, and pins extending from the frame across the springs, against which the bulges bear, substantially as and for the purpose set forth.

2. The combination, with the sashes and frame of a window, of the spring secured at its outer ends to the sash, and having upper and lower bulges, and formed with the semicircular bend f, the staple g, and pins extending from the sides of the frame against which the bulges of the spring bear, substantially as and in the manner described.

In testimony that I claim the foregoing as my own I affiX my signature in presence of two witnesses.
