Application filed May 9,

My invention relatcs to improven'ients in casement vvi udows having one or more sashes, and it consists in the combinations, coiui'tructions and. arra igenients' hercihii tcr described and claimed.

An object of my invention is to provide a casement window which is cmistructed so as to be hung with the miniu'iuin amount oi work and which has means for supporting itself: in the window 'lrame tor permittii'i the carpenter to use both hands in socurin the ow frame and for adji'mting the sash w aspect to the frame.

it further obj t of my invcnti on is to provide a device or he type described which may be rcniovcd for n s, or the like by merely unscrewing two screws.

A further object oit' my invention is to provide a device oi ti o, type do ibcd which is extremely sinpiple in re ix"; ion and which s 'gut adjnstnumts between e sash and win- :t'rame may be made without the necessity device to the wr strating certain of the mechanism.

.iiigure 3 is a section along the line 3-3 oi Figure 1;

Figure 1 is a perspective view of a shoe used in the device;

Figure is a perspective view of the novel link construction; and

F i gurc 6 is a section along the line (36 of Figure 5.

In carrying out my invention Iprovide a casement :lrame 1 and in the bottom rail 2 and top rail 3 l mount guide members of the shape shown in Figure 4. These .i'i'icn'ibcrs are secured in place by any means suchv as screws, or the like and extend parallel. with the plane of the window.

Upon each guide member 4; I mount a shoe 5 of the shape shown in Figure 4-. This shoe is movable along the niiember 4i; and carries a pivot rod 6 which is adapted to project up into a sash 7 as shown in Figure 2. The sash 1927. Serial N0. 189,981.

7, of course, is provided with bores for re ceiving the rods or pins 6.

Before the sash 7 is disposed in place, the shoes 5 may be moved with respect to each other so that the sash 7 may be pivotally secured to the lower shoe first and then he tilted at an angle so as to align. pin 6 carried by the upper shoe with the opening in the upper part oi? the sash. The sash may then be swung into vertical. position, thus aligning the shoes 5 vertically and causing the shoes to pivotally support the sash. The sash carries bearing plates 8, see Figure 1, which are secured to the sash by screws, not shown, passed through openings 9. The plates 8 have openings 10 for receiving the pins 6. This construction prevents the openings in the sash from becoming enlarged through wear.

.i e'torc the sash 7 has been hung in place the links 11 are secured to the sash by fastening pivot plates 12 to the sash. The position or the plates 12 on the sash 7 may be detc i'r ned without measuring any part of the ow frame itself. In locating the plates 12 in laid upon the sash so that the brackets 13 coincide with the edge 14 of the sash 7. The plates 12 may now be secured to the sash 7 in the position they will assume after the brackets 13 have aligned with the edge 14 in the manner 1' netthat the plates 12 may be secured to'the sash prior to the time that the sash is hung between the shoes 5, or after.

One of the principal features of the inven: tion lies in the fact that the links 11 may be secured. to the frame 1, while the sash 7, is pivotally supported and without the need of the carpenter holding the sash with one hand and securing the brackets 13 to the frame 1 with the other. The carpenter merely places the brackets 13 in the position shown in Figure 3 and secures the brackets in place by means of screws 15.

From the foregoing description of the various parts 01 the device the operation th'ercoil may be readily understood.

Figure 3 shows the sash 7 partially open, which. is the aqiiproximateposition the sash their proper positions the links 11 are described. It should be noted will assui'ne while the brackets 13 are being Cll 17 for permitting the plate to be moved with respect to the bracket 13, thus moving the pivot point between the link 11 and the bracket without the necessity of removing the screws 15. Figure 3 clearly shows how the .screw 16 may be moved in the slot 18 and then their new posit-ions. f course, the second adjustment of the sash in the standard window frame is not so firmly mounted as the first. This disadvantage is overcome with the present construction because the adjust ment of the sash 7' may be accomplished by moving the screw 16in the slot- 18. The keeper plate 17 has a threaded opening for the screw 16 and acts as a nut for reciving a screw. Figure 5 clearly shows how the plate has upwardly turned flanges 15 which bear against the edges of the bracket 13 for guiding the keeper plate along the bracket. The sectional view in Figure Qfurther shows how the sash 7 is provided with a lip 20 at the top and bottom thereof for covering the shoes 5 and the guide members d.

In Figure 2 I show a slight space between thesash 7 and the window sill and also a slight space between the bottom of the lip 20 and the window frame. It is well known that windows sweat and that the moisture collects in drops and flows cown on the inside of the window sash. This moisture usually collects between the sash and the window sill and of course in time rots away the wood at this point. I ith my device the member 4: acts as a water strip in that it guides the condensed water vapor fromthe inside of the window frame to the outside thereof. Water collecting on the metal parts will not rot the wood away when flowing from these parts over the bottom of the window sill because there will be a complete drain for the water. In this way the window frame is preserved and will have amuch longer life than will the standard window.

Oftentimes it becomes necessary to remove the sash 7 either for repair work or for other purposes and to do this it is merely necessary to remove the'screws 16, which frees the lin {S 11 from the window frame and permits the sash to be removed from the pins 6 by inclining the pivotal edge of the sash at a slight angle so as to permit the pins to be removed from their places in the sash. The sash can again be hung in the frame and is secured in place by again tightening the set screws 16 which secure the links to the bracket 13.

In Figure 4 I show the shoe 5 as being provided with a leaf spring 5 of the shape shown. This spring bears against the vertical portion of the members i and has its ends bent around the ends of the shoe 5. The spring is disposed between the shoe and the member 4 and creates enough frictional pressure upon the member to hold the shoe in adjusted position 7 with respect to the member. Still a further feature from the present construction lies in the fact that the links 11 may be made of heavier material and of longer lengths for larger windows so that they will be able to withstand the strain to which larger windows are subjected.

lVith the standard casement window the links are intimately connected with the other parts of the window frame so that the same size links will be used for windows having a small area as well as windows having a large area. This, of course, should not be the case, because it places an undue strain upon the links when they are attached to sashes having a larger area.

Although I have shown and described one embodiment of my invention, it is to be under stood that the same is susceptible of various changes and I reserve the right to employ such changes as may come within the scope of the appended claims.

I claim:

1. In a device of the type described, a casement, a sash pivotally mounted in said casement, links connecting said sash with said casement, the means connecting said links to said casement including metal brackets permanently secured to the casement and having slots therein and bolts for securing said links to said brackets in adjusted position.

2. A casement window comprising a frame, guide rails disposed at the bottom and at the top of said frame, shoes slid-able on said rails and carrying pins, and a sash having aligned openings extending parallel with and disposed adjacent to one of its vertical edges for receiving said pins, said pins being of such a length as to permit the rails and shoes to be first secured in place and then the sash mounted on one pin and then tilted at its opposite end for permitting itto receive the other pin.
