HINGE.

Specification of Letters Patent. Original application filed March 1, 1911, Serial No. 611,596.

Patented Au g. 6, 1912. Divided and this application filed February Serial No. 680,380.

To all whom it may concern:

Be it known that I, Anoinnam) PnnNTion, of the city of Toronto, in the Province 0" Ontario, Canada, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates particularly to hinges adapted for use with windows or other closures, adapted to both swing on the hinges or to be slid lengthwise of the pivots of the latter, and my object is to devise a simple hinge which is disengageable when the window is to be slid up and which when the parts are engaged permits of the window being slid up and held raised suiticiently above the bottom stop to clear the latter when the window is to be swung on the hinges.

I attain my object by means of the construction hereinafter described and illustrated in the accompanying drawings, in which Figure 1 is an elevation of part of a window provided with my hinge. Fig. 2 is an enlarged front elevation of the hinge with the connection piece locked in raised relationship to the hinge members. Fig. 3 is a similar View with the connection piece in disengageable relationship to the hinge members. Fig. 4 is a cross section of the hinge in the position shown in Fig. 2. Fig. 5 is a similar View of the modification shown at the upper part of Fig. 1.

In the drawings, like numerals of reference indicate corresponding parts in the different figures.

Referring particularly to Fig. 1, part of a window frame is indicated by the numeral 1 and part of a window sash by 2. The hinges shown thereon each comprise a hinge member 3 adapted to be secured to one of two relatively movable parts. In the suitably spaced knuckles 4 of the hinge member 3 is secured the pin 5. The hinge member 6 is provided with the knuckle 7 which swings on and is also vertically movable on the pin 5 between the eyes 4. A connecting piece 8 is adapted to be secured to the other of the two relatively movable parts with which the hinge is to be employed. This piece 8 is adapted to be engaged by longitudinal movement with the hinge member 6 preferably in the following manner :-The sides of the part 8 are dovetailed (see Figs. 4 and 5) and are adapted to engage a similarly shaped recess in the hinge member (3. At one end, preferably the upper, of the part 8 is formed an extension 9 which has its outer surface flush with the outer surface of the part 8, but which is narrowed in width so that it will not engage with the sides of the recess in the part 6. In the outer surface of the part 8 I form the recess 10. In this recess the head 11 of the plunger 12 is adapted to engage (see Fig. 4). This plunger is set in a counterbored hole in the hinge member 6 and is yieldingly pressed toward its recess engaging position by the coil spring 13 engaging the head 11 and the shoulder 14 of the counterbored hole. The plunger 12 is provided with the button 15 by means of which it may be actuated by hand to release the head 11 from the recess 10.

The parts just described form a releasable catch to lock the connecting piece 8 to the hinge member (3 in a pro-determined position. These parts are omitted, it will be noted, from the upper hinge as one spring catch to a window is usually sufficient.

The operation of the hinge, when applied to a window, is as follows :-If the parts, including the window sash, are in the position shown in. Fig. 1, and assuming if he desired to swing open the window on the hinges, then the first step is to raise the window slightly; this slides the part 8 of the connecting piece of each hinge through the dove-tail recess in the hinge member 6 until the head 11 of the spring catch locks in the recess 10. \V hen the window sash is allowed to fall to sustain its weight on the hinges, the parts of each hinge will be in the position shown in Fig. 2 and the sash 2 will be held. slightly raised with its lower edge above the level of the upper edge of the stop 16 on the window sill. The window may now be swung open, assuming of course that the sash cord, if any, at the side opposite the hinges has been disengaged. If, when the parts are in the position shown in Fig. 1, it be desired to raise the window, each hinge member 6 is slid up on the pin 5 till the dove-tailed recess in the hinge member disengages from the part 8 (see Fig. 3) when the member (3 may be swung back out of the path of the connecting piece 8 as the latter moves up with the window. lVhen the member 6 is to be reengaged it is put in the position shown in Fig. 3 and then pushed toward the connecting piece and at the same time downwardly toreengage it with the part 8 of said connecting piece.

It will be noted that the main function of the extension 9 is to guide the member 6 as it is moved to engage the part 8 and also to push up the head 11 of the spring catch so that manipulation of the button 15 is unnecessary when engaging the said hinge member and engaging piece.

It will be noted that the successful operation of my hinge depends upon its being adapted in either form to assume either the position shown in Fig. 1 with the hinge member 6 in its lowest position relative to the hinge member 3 and in engagement with the part 8 of the connecting piece or the position shown in Fig. 3 with the hinge member 6 in its raised position relative to the hinge member 3 and disengaged from the part 8, and in the form used preferably at the bottom of the sash to assume the position shown in Fig. 2 with the hinge member 6 in its lowest position relative to the member 3 and both engaged with and locked in a predetermined position relative to the part 8 of the connecting piece.

Attention is directed to the fact that when the sash is to be raised the parts will usually be in the position shown in Fig. 1, then it is merely necessary to slide up the part 6 as the spring bolt is not, when the parts are in this position engaged in the recess 10. If the parts are in the position shown in Fig. 2- when it is desired to raise the window it will be necessary, of course, to release the spring bolt and to return the parts to the position shown in Fig. 1, before sliding back each hinge member 6.

This is a division of application No. 611,596, filed March 1st, 1911.

What I claim as my invention is 1. In a hinge the combination of a hinge member; a second hinge member pivotally connected with and longitudinally movable on the first hinge member; and a connection piece slidably engageable with and disengageable from said second hinge member by movement longitudinal of the hinge.

2. In a hinge the combination of a hinge member; a second hinge member pivotally connected with and longitudinally movable on the first hinge member; a connection piece slidably engageable with and disengageahle from said second hinge member by movement longitudinal of the hinge; and releasable means for holding the second hinge member and the connection piece, when engaged, in a predetermined position relative to one another.

3. In a hinge the combination of a hinge member; a second hinge member pivotally connected with and longitudinally movable on the first hinge member and having a longitudinal dovetailed groove formed therein; a connection piece adapted to slide in said recess; and an extension at one end of the connection piece narrower than the main part of the connection piece but having its outer surface substantially flush with the outer surface of the main part of the connection piece.

41. In a hinge the combination of a hinge member; a second hinge member pivotally connected with and longitudinally movable on the first hinge member and having a lon gitudinal dove-tailed groove formed therein; a connection piece adapted to slide in said recess; a releasable catch adapted to hold the second hinge member and the connection piece, when engaged, in a predetermined position relative to one another; and an extension at one end of the connection piece narrower than the main part of the connection piece but having its outer surface substantially flush with the outer surface of the main part of the connection piece.
