M/l EA/ 70/? 1 JAMiS 6. PIE/PR Y BY @WZMA @M ATTORNEY United States Patent 3,206,804 ADJUSTABLE MOUNTING FOR SASH SLIDE RAIL James G. Perry, 12981 Capital Ave., flak Park 37, Mich. FiledJuly 28, 1964, Ser. No. 385,704 2 Claims. (Cl. 20-522) This invention relates to the building industry and has particular reference to removable sash windows.

An object of the invention is to provide an adjustable mounting for the slide rail of a removable sash window, such as disclosed in my co-pending application No. 245,708, filed December 19, 1962.

Another object of the invention is to provide an adjustable mounting for the slide rail of a removable window, which is constructed and arranged, so that the slide rail may be stored and shipped in flat condition and without the mounting screws protruding from the slide rail during the storage and shipment ,of the device.

Another object of the invention is to provide an adjustable mounting means for a compound weather strip, or slide rail, for a removable sash window. In this disclosure a compound weather strip, or slide rail, will be understood to be a unitary weather strip, or slide rail, which serves both the upper and lower sash of a double hung window.

Another object of the invention is the provision of an adjustable mounting for the slide rail of a removable Sash window, which may be quickly and efiiciently mounted to the side jamb ,of the window frame by using the openings provided in slide rail and retainer for guides in drilling holes in the side jamb for the subsequent introduction of the screws which are to mount the slide rail to the jamb. This is an important feature of the invention as it enables the installer to perfectly align the slide rail when it is installed. This result is not possible with devices now known to the public because the mounting screws are permanently fixed to the slide rail at the factory and always protrude beyond the rail. The protrusion of all of the screws beyond the back face of the slide rail before and during installation provides a poor support and causes a wobbling and unsteady movement of that portion of the slide rail, which is removed from the mounting screws initially worked on during the attachment of the slide rail to the side jamb of the window frame. Under such conditions it is impossible to properly align the slide rail. Unless there is a perfect alignment of the full length of the slide rail during its installation, there always will be difficulty in sliding the window sash and removing the same from the adjustable slide rails.

This invention may be considered an improvement on the invention disclosed in Patent No. 3,103,711, issued to Teggelaar. In the reference patent the mounting screws are permanently staked to the support members, or retainers, which hold the springs in position, consequently the mounting screws always protrude from the slide rail during the storage and shipment of the slide rails, and remain so until the screws are permanently set into the side jambs of the window frame. As indicated above, the permanent protrusion of the mounting screws makes it very diflicult to properly align the slide rails during their installation.

The instant invention has a further advantage over the device disclosed in the reference patent, in that it allows greater adjustment between the support members, or retaining members, and the slide rail. In the reference patent, because the attaching screws are staked to the support member, or retainer, the adjustment between the support member, or retainer, and the rail is limited to the distance between the ends of the support member, or retainer, and the body of the slide rail. In the instant invention, however, because the adjustment screw is not staked to the retainer, or support member, but enters the openings in the rail and support member freely and is later fixed to an independent washer, which abuts the small end of the spring, the spring may further be placed under greater compression, by rotating the screw, even after the ends of the support member, or retainer, have contacted the body of the slide rail. Because of the ability to further compress the spring as hereinabove described, greater adjustment may be made on the slide rail than is possible with the structure disclosed in 'the reference patent. The additional adjustment which is made possible with the instant invention is quite important when it is necessary to compensate for a window sash which may have been milled undersize as to overall width.

It is therefore an object of this invention to obviate the foregoing difliculties and to provide .an adjustment for a slide rail which has many advantages over devices of that character now known to the public. V I

The foregoing and other objects and advantages of the invention will become more apparent as the disclosure proceeds, reference being made from time to time to the accompanying drawing, forming a part of the within disclosure, in which drawing:

FIG. 1 is a transverse section taken through a compound weather strip or slide rail embodying the invention. This view shows the weather strip, or slide rail, without the attaching screws, and shows the condition of the device when it is in storage, or intransit, prior to its installation on a window frame.

FIG. 2 is a transverse section taken through a window frame to which the device shown in FIG. 1 is to be mounted. This shows the double hung window frame before the window sashes are installed in the frame, and shows the mounting screw as it is about to be entered in the bore (broken lines) previously drilled in the side jamb of the frame, using the openings in the weather strip, and the retainer as guides. In this position no compression has yet been put on the spring by the screw.

FIG. 3 is a section similar to FIG. 2, but illustrating the window frame after the upper and lower sashes have been installed in the frame, and after the mounting screw has been inserted in the side jamb of the window frame, and drawn up so that the retainer is inoperative and the spring is under compression between the washer and the back of the weather strip.

Referring now more particularly to the drawing, it will be understood that in the embodiment herein described the reference character 7 indicates, in general, the body of a weather strip, or slide rail, for a double sash window frame.

In this embodiment the member 7 is preferably made of a rigid extruded, plastic material, and is constructed and arranged so that it serves both the upper sash and the lower sash of a window. The member 7 is of sufficient length to extend the top to the bottom of a window opening, and as stated before, is adapted to Weatherstrip both the upper sash and the lower sash and is resiliently mounted as hereinafter described, so that. either sash may be removed from the frame by compressing the flexible mounting to provide clearance, whereby the sash may be removed as in conventional practice.

The member 7 is provided with two hollow rectangular portions 8 and 9, which engage channels 10 and 11 (FIG. 3), formed in the side members of the window sash. Each member 8 and 9 (FIG. 1) is provided with a longitudinal opening 12 to receive the balancing mechanism (not shown) of the window sash.

The wall 13 of the slide rail is provided with an opening 14 of sufficient diameter to permit the passage therethrough of a mounting screw 15, by which the slide rail 7 may be secured to the side jarnb 16 of the window frame (FIGS. 2 and 3). The window frame is 33 also provided with conventional back stop 17, front member 18, and trim molding 19.

The opening 14 in the wall 13 has an inturned edge 20, which serves to hold against displacement one end of a compression spring 21, the other end of which abuts a washer 22, which is carried in a U-shaped support member, or retainer 23. The outer ends of the retainer 23 are held behind shoulders 24, forming part of the weather strip, or slide rail 7.

The spring 21 is positioned between the wall 13, and the washer 22, and the retainer 23, under a sufficient degree of compression to hold the parts in position during storage and transportation, as illustrated in FIG. 1.

The washer 22 and the retainer 23 are each provided with a bore 25, 25A, having a sufficient diameter to permit the shank of the screw 15 to pass therethrough. The bore 25A in the retainer is larger than the bore 25 of the washer. The washer 22 is of the lock-on type and is constructed so that when the screw 15 is drawn down, so that the head of the screw 15 contacts the washer 22, as shown in FIG. 3, the washer 22 will then become locked on the shank of the screw, and will rotate with the screw and may be advanced or retracted as the screw is turned.

It will be understood that after the screw 15, and the washer 22, are locked together, and the screw 15 is then backed out of the bore 26 a distance, increased compression is built up in the spring 21, as shown in FIG. 3. In this condition the retainer 23 becomes loosely mounted on the shank of the screw 15 and serves no further purpose.

By the same token, the compression of the spring 21, now being between the washer 22, and the wall 13 of the slide rail, it is obvious that various degrees of compression can be exerted on the spring 21 by the rotation of the screw 15.

This is an important feature of the invention as it enables the applicant to get a greater amount of adjustment on the slide rail than is possible with devices now known to the public. This arrangement also permits the combined openings in the wall 13, the washer 22, and the retainer 23 to be used as guides in drilling the bore 26, before the mounting screw is inserted. With this arrangement the slide rail can be accurately mounted on the side jamb 16 and on the job during installation.

In FIG. 3 the reference character 27 indicates the upper sash, and the reference character 28 indicates the lower sash of a double hung window. Each sash 27 and 28 is provided with the conventional glass panel 29.

It is believed that the operation of the device is obvious from the foregoing description.

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

1. A slide rail assembly for a side frame member of a removable window structure, comprising a body having a longitudinal portion received in a channel of a side stile of a window sash, said body being integral and being snugly received between inner and outer stops of said frame in a channel of said frame, a spring retainer secured to the median inner part of said body, a lock washer loosely received in said retainer, a com pression spring positioned between said washer and said body, said body and retainer having aligned openings therein for loosely receiving a screw, said lock washer having an opening therein of sufficient diameter to receive only the shank of said screw and be locked thereon, said screw being adjustable so that the retainer and lock washer may move as the screw is rotated.

2. An assembly as in claim 1, said body being of a width to have portions received in channels in side stiles of both an upper and a lower sash, said retainer being made inoperative on said screw after a predetermined degree of compression is built up in said spring between said washer and said body by the rotation of said screw.
