$PECIFICATION forming part of Letters Patent No. 498,225, dated May 30, 1893.

Application filed January 26,1893- Serial No. 459,'799. (N0 model.)

lowing is a specification.

This invention relates to sash-frames, and has for its object to provide an anti-rattling and anti-frictional dustproof sash-frame that will accommodate itself automatically to the diiference in size of the sash-frame produced by the swelling or contraction thereof; the

parts thereof being simple and effective in their operation and readily understood, and

with this object in ,view the invention con sists of the construction and arrangement of the parts as will be more fully'hereinafter described and claimed. v

In the drawings: Figure 1 is an elevation of a window and sash-frame, a portion of the window-frame being broken away, and show-' ing the improved construction in connection with the sash-frame; Fig.2 is a longitudinal vertical section through the center of the parts-shown by Fig. 1. Fig. 3 is a detail perspective View of the siderail of the sash frame and the friction-bar of the improved construction shown disconnected fromeach other. v

Similar numerals of reference indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, the numeral 1 designates a window-frame, which may be located in the side of a car or in any other desired position, and wherein is mounted a sashframe 2, having its left-hand vertical side-rail 3 formed with a recess 4 in its outer edge that has recesses 5 of greater depth extending inward to the said rail, nearer the upper and lower ends thereof, and wherein are seated crescent-shaped springs 6, that are held in position by single centrally-located dowel pins or rivets 7, and the free ends of the said springs normally stand outward beyond the plane of the termination of the said side-rail. If desired, however, these springs may be replaced by any well known mechanical equivalent, and thereagainst is loosely held a cushion strip or frictional bar 8, of the same thickness as the rail 3, and substantially of T- strip or bar are adapted to engage to hold the latter against vertical movement and away from its properposition relatively to the rail 3. By this means it will be seen that a fastening for the said strip or bar becomes unnecessary and that the mounting of saidparts is simpliq, tied with the same relative amount of efti-.

ciency of operation.

The springs 6 operate against the cushion strip or frictional bar 8, keeping the latter up against the Window-frame at all times. When the sash-frame swells it cannot bind between the window-frame, for there is a small space allowed between the sash-frame and the said cushion strip. The swelling of-the sash-frame partially closes this small space and forces the springs backward into their recesses, and by this means it will-be seen that an anti-friction sash-frameis provided. When the sash-frame shrinks, the springs force the'c'ushion strip outwardly and hold it in contact'witli the .win- I dow-frame, thereby forming ananti-rattling sash-frame. By keeping the sash-frame closely fitted to the window-frame in the manner set forth, and allowing no crack or crevice whatever, it will be seen that all air and dust are excluded. g

It will be understood that the cushion strip has just enough playlongitudinally' between the metal plates -9 to permit the springs to adjust the same outwardly and obviate lost motion when the sash-frame is raised or lowered.

The improved attachment is adapted to be placed on the left side of the sash-frame, and therefore does not interfere with any catches used on the window-frame and adapted to engage the sash-frame. Further, the width of 6o against which the opposite ends of the said I that the cushion strip is quite narrow, and by this means all the working parts are hidden behind the window-stop, giving the appearance, outwardly, of a solid sash-frame.

It will be understood that the sash-frame may be of any size or relative shape so long as it is applicable to receive the improved attachment, and may be cheaply manufactured and applied.

Having described the invention, what is claimed as new is- In combination with a window-frame, of a sash-frame having one of the rails thereof formed with a recess in the edge thereof from which deeper recesses extend inward near the l the presence of two witnesses.
