. 2 Claims. l I

The present invention relates to a window frame and more particularly to a window'of the type commonly employing double hung sash.

In the double hung type of window frame now in common use the stiles are provided with boxes in which run counterweights which are connected to the sashes for counterbalancing them and holding them at selected positions in the window opening. The use of counterweights requires the mounting of pulleys in the upper reaches of the stiles and the use of flexible members trained over the pulleys and connected to the counter weights and sashes. In the ordinary window frame the stiles are also provided adjacent their lower ends with access openings through which a weight is accessible for service should a flexible member to which the weight is attached become broken. Such access openings are normally closed by separate panels held in place by fastening means which frequently become so covered by paint as to render it almost impossible to remove .the panel when the weight covered thereby becomes inoperative. Moreover, due to the fact that the sashes must slide freely between the stiles, the stops and the parting strips in order for the counterweights to properly function, gaps between the frame and the sashes result, ,and these gaps are not only not weathertight but will permit a sash to rattle in its frame.

The primary object of the present invention is to so. construct a window that the sashes are not only weathertight but which willnot rattle.

Another object of the present invention is to hold the sashes in selected positions in their frames without the necessity of employing counterweights, counterbalancing springs or the like.

A still further object of the present invention is to facilitate the removal of the sashes from a window frame for cleaning, glazing, repairs or for any purpose desired by the user. v

The above and other objects may be attained by employing this invention which embodies among its features, shoes mounted adjacent a stile and between the stops of the frame of a double hung window for movement in a path which lies perpendicular to the stile, springs mounted between the stile and the shoes for yieldingly urging the shoes to move in said path away from the stile and means carried by the shoes and extending through the stile for holding the shoes against movement by the springs.

Other features include screws carried by the shoes and extending through the stile and strips carried and threadedly engaged by the screws and bearing on the sides of the stiles remote from the shoes to form stops by which the movement of the shoes is arrested.

In the drawings:

Figure 1 is a rear elevational view of a window frame embodying the features of this invention.

Figure 2 is an edge view of said window frame.

Figure 3 is a horizontal sectional view taken substantially on line 33 of Figure 1, the upper sash being shown in slightly lowered position.

Figure 4 is an enlarged sectional view through the shoes and strips.

Figure 5 is a fragmentary enlarged side view 0 a screw, and

Figure '6 is a perspective view of a spring retaining ring employed to hold a, screw in a. shoe.

Referring to the drawing in detail a window frame designated generally It] comprises a sill l2, a lintel I4 and stiles l6 and I8. The stile I6 is of conventional form and includes outer and inner stops 2!] and 22 between which is supported a conventional parting strip 24 which defines with the stops 28 and 22 runways 26 and 28 for the outer and inner sashes 30 and 32 respectively.

The stile I8 is provided with outer and inner stops 34 and 36 respectively but unlike the stile IS the space defined between the stops 34 and 36 is of somewhat greater depth than the space defined between the stops 20 and 22. Extending through the stile i 8 are horizontally spaced rows of vertically spaced openings 38 and 40.

Mounted in the space defined between the stops 34 and 36 adjacent the stile I8 is a shoe designated generally 42 which comprises an elongated rectangular body 44 of wear resistant fiber carrying adjacent one longitudinal marginal edge an outstanding flange 46 which when the shoe is in place forms a parting strip between the sashes 30 and 32. Formed in the body 44 is a longitudinal row of openings 48 which increase in diameter as they approach' the side of the body adjacent the flange 46 for the reception of supporting and guide members 50 which in the present embodiment of the invention take the form of flat headed screws. The openings 48 in the body 44 align with the openings 38 in the stile It so that the guide members 50 may pass through the openings 28 and enter a stop strip 52 which is disposed against the side of the stile IR remote from the shoe 42. A compression coiled spring 54 encircles each guide member 40 between the stile l8 and the shoe 42 to exert pressure on the shoe and urge it away from the stile l8. The body 44 and flange 4B define a guideway 41 adjacent the stile I8 for the sash 32.

Mounted in the space defined between the stops 34 and 36 and the stile [8 adjacent the shoe 42 is a shoe 56 which comprises an elongated rectangular body 58 of wear resistant fibrous material which like the body 44 is provided with conical recesses 60 for the reception of supporting and guide members 62 which like the members 50 comprise flat headed screws. These supporting and guide members 62 extend through the openings 60in=the stile l8 and enter a st'oip grip 64 which like the stop strip 52 bearsagains't the side of the stile I8 remote from the shoe 55.

A compression coiled spring 66 encircles each' supporting and guide member 62 between'ttie f stile l8 and the shoe 56 to yieldingly urge the shoe 56 away from the stile l8. shoe 56"56- "operates with the stop 34 and flange-Min defining a guideway 68 for the sash 30.

By reason of the fact that the heads 12 are of less thickness than the shoes it will be obvious that no scoring of the side rails of the sashes will be experienced and because of the pressure of the shoes on the sashes, the sashes will be retained in selected positions fin thefrunways frictiohaI contact with 'the shoes "and the stile T6.
