Y UNITED STATES PATENT OEEIoE.

JAMES WEATHERS, OF INDIANAPOLIS, INDIANA.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 443,884, dated December 30, 1890. Application filed October 11,1890. Serial No. 367,780- (llo model.)

T0 all whom it may concern:

Be it known that I, JAMES WEATHERs, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Sash Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

Referring to the drawings annexed, Figure 1 represents a View, partly in section and partly in side elevation, of a portion of a window-frame and sash showing my improved holding device applied thereto; Fig. 2, a horizontal sectional view thereof; and Fig. 3, a detail perspective view of the cast frame of the holder.

The invention is designed to provide a simple device for application to a window, whereby the sash may be readily adjusted and supported at any desired elevation, as will more fully hereinafter appear.

The invention consists in certain novel features of construction and arrangements of parts that will fully hereinafter appear, and be particularly pointed out in the claims appended.

In the drawings, A designates a cast-metal frame adapted to be inserted in an inclined recess in the windowjamb or frame, the bottom of the recess inclining upwardly and away from the window-sash.

The frame consists of a main plate provided with a longitudinal slot, whereby it may be adjustably secured to the inclined bottom of the recess, and longitudinal flanges a, formed along its side edges and extending beyond the upper end of the plate. These side flanges are formed into ways or tracks a a, upon which work the trunnions of gravitating friction-rollers b b, the rollers being separated from each other and supported the proper distance from the window-sash. Abutments or hooks b b 1), formed on the ways, serve to prevent the rollers leaving them. Under the upper ends of the ways a is placed a rubber or other spring 0, which serves to keep the upper end of the frame normally pressed outward a limited distance. As thus constructed, it will be observed, the gravitatin g rollers normally press against the edge of the sash, and the friction caused by the wedging or binding of the rollers between their inclined tracks and the sash will be sufficient to support the latter at any desired point. When the sash is raised, the rollers will automatically move upward a sufficient distance to release the sash, as is evident. To lower the sash it is simply necessary to press the same forcibly downward, whereupon the frame A will be caused to yield sufficiently to let the trunnions of the rollers rest upon the hooked abutments, when the wedgin g action will cease sufficiently to permit the sash to be forced down, the trunnions of the rollers revolving in their hooked abutments as the sash descends.

The lower roller, as its action is supplemental to the upper one, may be omitted Without departing from the spirit of the invention.

By means of the longitudinal slot in the main plate of the frame and the screw that passes therethrough into the frame the framemay be readily adj ust-ed to work properly and bring the required pressure upon the sash, the amount of pressure being determined by the weight of the latter.

As shown in Fig. 2, the rollers may be provided with a central annular ring or flange 1), adapted to work and press upon a strip of rubber or other elastic material secured in the bottom of a longitudinal groove formed in the adjacent edge of the sash, the purpose of this construction being to compensate for any inequalities in the sash and permit the same to work smoothly in cases. When the sash is true and even upon its edges, the plain surfaced rollers shown in Fig. 1 will serve equally well.

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

1. The combination of a metallic frame A, provided with a longitudinal slot, whereby it may be adj ustably secured within a recess in the window-frame, and longitudinal inclined ways a, these ways having formed on them hooked abutments b, a roller journaled on the said ways and confined thereon by the said hooked abutments, and an elastic block arranged behind the upper end of the said frame A and adapted to keep it normally 7 pressed outward, substantially as described. 2. The combination of a frame provided with inclined ways and abutments, a spring behind the upper end of said frame and I against the rubber strip, substantially as deadapted to keep it normally pressed outward, I scribed. 1 a roller working upon the said inclined ways In testimony whereof I aflix my signature in and provided with an annular flange, and a presence of two witnesses.
