Application filed December 27, 1927.

This invention provides a window including a frame and sliding sashes and obvlates the usual counterbalancing means, such as weights, cords and pulleys, and insures close joints which is essential to the exclusion of air, dust and rain, and enables the sashes to be easily and quickly placed in poslt on or removed, and compensates for expanslon 1n wet weather and contraction in dry periods, so that the sashes may be moved up or down with the greatest facility at all seasons and will remain in the adjusted position.

I The invention simplifies windows as ord1- narily constructed, materially reduces the cost, both of manufacture and maintenance and enables the sashes to be instantly removed and replaced without the use of tools which is a decided advantage for cleaning, painting, glazing, entire extent of the window openmg.

While the drawings illustrate a preferred embodiment of the invention, it-is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes 1n the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof. v

For a full understanding of the invention and the merits thereof reference is to be had to the following description and the drawings hereto attached, in which,

or where it is required to utilize the Serial No. 242,620.

Figure 8 is a modified form of the guides.

Corresponding and like parts are referred to in the following description and designated. in the several views of the drawings by like reference characters.

The window opening is comprised between the vertical side pieces 1 and receives the window frame including the jambs 2 and top and bottom cross pieces 3 and 4, respectively. The window frame is of a width less than the distance between the side pieces 1 to provide spaces between the jambs 2 and parts 1, said spaces being closed by trimming 5 and 6. The jambs 2 are formed with slots 7 which extend the length thereof, as indicated most clearly in Figure 2 of the drawings. The frame has top and bottom sashes 8 and 9 fitted thereto in the accustomed way so as toslide up and down, the side bars of the sashes are grooved in their outer faces, as indicated most clearly in Figures 3 and 4 of the drawings. The grooves 10 extend throughout the length of the side bars. The sashes have a fit between the jambs 2 of the window so as to move freely at all times.

A. guide strip is provided for each slot 7 of the jambs 2 and an edge portion projects to enter a groove 10 of a sash to retain it in place within the frame. This guide strip may be of any construction and may consist of a flatpiece 11 of wood, and a cross strip 12 attached to an edge thereof to limit the movement of the guide and prevent its displacement through the slot 7. The slots 7 and the grooves 10 are of corresponding width to accommodate the guides of. uniform thickness. The guide 13 indicated in Figure 8 consists of a strip of wood having diagonally opposite corner portions rabbeted to provide parts to pass through a slot 7 and enter a groove 10. This form of guide is reversible. Springs 14 normally exert a pressure upon the guides to hold them projected through the slots 7 and in engagement with the grooves 10. The springs 14 are preferably of the open coil type and are positively retained in place by fastening means. A pointed pin 16 is driven into each of the side pieces 1 and its projecting end is threaded to receive a nut 17 and a washer 18. The nut 17 provides for adjusting the tension of the spring 14 to cause the guide to engage the sash with a greater or less degree of pressure to hold the same at the required adjusted position. The

19 is threaded into the rear portion of the guide and washer 20 mounted thereon enters the opposite end of the spring 14 and in conjunction with the pin 16 retains the spring in proper position. The sashes have a loose fit between the jambs 2, so as not to bind when swollen in damp weather. The guides are of a. width to insure the projecting edges engaging the bottoms of the grooves 10 and compensate for wear and for contraction of the sashes during a dry spell. The springs 14: exert a pressure upon the guides to cause sufficient friction between said guides and the sashes to hold the latter in adjusted position. It is observed that the guides extend across the joints formed bet-ween the sashes and the jambs, thereby preventing the passage of wind, dust and rain. lVhen the guides are pressed so as to clear the window openin as indicated in Figure of the drawings, the sashes may be easily placed in position, or removed. A spreader 21 extending between the jambs of the window frame holds the guides pressed outward against the tension of the springs 14. A spreader 21 is located above and below the sash, thereby admitting of the same being readily placed in position or removed from the frame. WVhen the sash has been placed in position and the spreader-s 21 removed the springs 14 press the guides beyond the jambs 2 into engagement with the grooves of the sashes, which are thereby retained in place. Stops 22 and 23 supplement the action of the guides, the stop 23 being removed when it is required to displace a sash or apply the same to the window frame. A close joint is obtained between the meeting rails of the sashes 8 and 9 by means of strips 24 which are arranged to overlap, said strips being attached to the opposing sides of the rails, as indicated most clearly in Figure 4 of the drawings.

In the modification shown in Figure 6 the strips 25 have their meeting port-ions beveled, and an edge. portion reduced. This form of joint insures a close fit between the meeting rails when the sashes are closed.

Because of the close fit between the sashes and the frame there -is no necessity for weather stripping. Moreover, the sash will not rattle and the window is noiseless and dust and weather proof.

Having thus described the invention, I claim:

1. In a window, the combination with the frame and sliding sash, of a guide carried by the frame, and adapted to engage a groove of the sash, and a spring normally exerting a pressure upon the guide to hold it in frictional engagement with the sash, whereby to hold the latter in an adjusted position, and means for varying the tension of the spring to regulate the frictional engagement between the guide and sash.

2. The combination with a window frame having a slot in. a jamb thereof, and a sliding sash formed with a groove to match the slot of the frame, of a guide fitted in the slot of the frame and having an edge portion entering the groove of the sash, an open coil spring between the guides and adjacent side piece of the window, and holding means for the spring, the same including a pin having an end portion threaded and a washer and nut mounted upon the threaded part of the pin.

In testimony whereof I alfix my signature.

SAMUEL A. MoCLELLAN. [Ls]
