DETACHABLE HINGE FOR WINDOWS.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed February 16, 1911. Serial No. 608,896.

To all lwhom t may concern:

Be it known that I, MoR'roN A. GEORGE, a citizen of the United States, residing at Bishop, in the county of Inyo and State of California, have invented certain new and useful Improvements in Detachable Hinges for Vindows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sliding and swinging window sashes, and more especially to those of that type having a separable hinge; and the object of the same is to improve the construction of such a hinge so that it may be applied to a window alread)7 in place and without taking the latter' out of its bead.

Another object is to so construct and apply a hinge of this character that the sash may slide up and down but cannot swing except when in a certain position, and when it swings it cannot slide up and down nor can the hinge members be disengaged from either the sash or the frame.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side view of a portion of a window showing the application of the invention, parts being broken away and in section to illustrate the manner in which the sash cord is fastened when the sash is supported o-n the hinges. Fig. 2 is an enlarged side View of a portion of the sash and frame showing the construction and arrangement of the hinge and illustrating in full lines the operative position of the hinge and in dotted lines the manner inwhich the hinge is applied and brought to an operative position; Fig. 3 is a det-ail perspective view of the frame engaging member of the hinge; Fig. 4 is a front view of the sash member of a lower hinge; Fig. 5 is a side view of the frame member of said lower hinge; Fig. 6 is a vertical sectional view through the fastening devices for the stop strip on the opposite side of the frame from that to which the hinge members are connected.

In the embodiment of the invention I provide an upper hinge and a lower hinge.

The upper hinge consists of a sash member 1 adapted to be attached to the sash near the top and adjacent to one side of the same as shown, and a frame member 2 adapted to be secured to the adjacentportion of the window frame. The sash member 1 comprises a flat plate 3 having formed therein two key hole slots 4, 4a and having on its outer end a vertically disposed bearing eye 5. The frame member 2 of the upper hinge comprises an upright flat bar 6 having its upper end bent inward at an ineline as at 7 and then turned outward and downward in the form of a hook 8 having therein a notch 9 the purpose of which will be hereinafter described. In the lower end of the bar 6 is formed a vertically disposed slot 10 the purpose of which will also be hereinafter described.

On the outer side of the bar 6 between the slot 10 and the inclined upper end thereof is a bearing bracket 11 comprising a plate having a Width corresponding to the width of the bar 6 and having its ends bent outwardly at right angles and provided with bearing apertures 12. The bracket 11 is secured to the bar G by rivets or other suitable fastening means and when the members of the hinge are assembled is adapted to receive the eye 5 on the sash member of the hinge. When the eye 5 is engaged with the bracket said parts are connected together by a hinge pin or pintle 13 which is inserted through the bearing apertures 12 in the bracket and through the eye 5 as shown.

In order to detachably secure the sash member of the hinge to the sash I provide attaching screws 14 14 which are by preference ordinary round head screws seated in the upper cross rail of the sash t-he same distance apart as are the round ends of the key hole slots 4, 4, so that the latter may engage them in a manner well understood. The numeral 15 designates a supporting screw seated in the stop bead or strip at a point to be engaged by the notch 9 in the hook 8, and 16 is a catch pin also seated inV this bead or strip at a proper distancebelow the screw 15 to engage the slot 10 at this time and therefore prevent the frame member of the hinge from swinging in a plane at right angles to that of the sash. The numeral 17 designates a stop pin or screw seated in the face of the side rail of the sash some distance inward from the head of the catch pin and relatively disposed with relation to the screws 14 14a so that the following action results: Ordinarily the window sash slides vertically between the beads or strips within the frame as usual. If now it it is desired to apply this hinge, the frame member 2 is first turned on its pivot 13 to a position at right angles to the plane'pccupied by the sash member 1, then the latter is canted a little farther than is shown in dotted lines in Fig. 2 so that the round ends of the key-hole openings 4 4a may be passed over the heads of the screws 14 14a, then the plate 3 is dropped a little and the frame member 2 turned on its pivot 13 until the parts assume the position shown in dotted lines in this view and the lower end of the bar 6 passes outside the stop 17 while the hook 8 passes inside the bead or strip above the supporting screw 15, and then the entire sash is lowered a trifle so that the parts assume the position shown in full lines in this view, the screw 15 acts as a fulcrum around which both members of the hinge swing, and the lower end of the bar 6 is drawn out of contact with the stop 17 and its slot 10 passed over the catch pin 1G just as all parts of the hinge come to rest and the window sash is firmly and thoroughly supported thereby. It is to be understood that the bead at the other side of the window is removable in a manner described below or otherwise, and when it is removed it will be clear that the sash can be swung inward on this improved hinge, the sash member 1 turning on the pivot 13 around the frame member 2 in a manner which will be clear. As soon as it is so swung, however, the weight of the sash is applied to the frame member 2 in a plane at right angles to the plane of the entire window, and as the catch pin 16 engages the slot 10 and the frame member cannot move in this plane the sash cannot be raised or lowered while it is swung out of its usual position. On the other hand, having restored the sash to its usual position as shown in the drawings, if now it be raised the incline 7 strikes the screw 15 and throws the frame member 2 outward from the full lined to the dotted lined position shown in Fig. 2 when the lower end of the bar G strikes the stop pin 17 and the plate 3 can be thrown no farther and hence its key-hole slots 4 4EL cannot be disengaged from the screws 14, 14a, although the sash and both members of the hinge can be raised and lowered but cannot be swung inward. In rising the incline passes over the head of the screw 15, after which the weight of the plate 3 and both members of the hinge will hold the parts in this position, and in descending as soon as the notch 9 rengages the screw 15 it again acts as a fulcrum and throws the lower end of the bar G outward so that the slot 10 rengages the catch pin 16. Thus it will be seen that this improved hinge permits vertical movements of the sash so long as the latter stays within its stops or beads, and it permits a horizontal swinging movement of this sash only when the latter is lowered so that the hook engages the supporting screw at which time the lower hinge will be engaged in a manner to be described below and at which time of course the right hand bead must be removed. The construction of the hinge also permits its application to the face of the sash without removing the latterl from its beads and without having to` tighten up or loosen any screws, and in fact it will be clear that if the various parts are properly applied this hinge can be attached to the ordinary sash and will work successfully therewith if the right hand bead is rendered removable and the right hand sash cord (if therebe one) be detached from the sash.

lVhile the lower hinge may be of any suitable construction which will answer in connect-ion with the improved upper hinge above described,by preference it consists of a sash member 18 comprising a flat plate 19 having in its upper end a right angular notch 2O and in its lower end a vertical notch 21. On the lower end of the plate 19 adjacent to one edge thereof isformed a vertically disposed eye 22 which is adapted to be engaged with the frame member of the lower hinge said frame member being in the form of an ordinary screw hook 23 which is screwed into the stop strip of the frame in position to receive the eye 22 when the upper hinge is in position. The sash member 18 is detachably secured to the sash by ordinary round head screws 24 which are arranged in the sash in position to be engaged by the slots 2() and 21 of the plate 19.

It will be understood that when the sash is to be supported and swung on the hinges that the stop strip 25 on the opposite side of the frame will be removed, and in order to provide for the ready removal of said strip I preferably provide the same with fastening screws 26, said screws having a threaded inner portion 27 and a reduced outer portion 28 on the outer end of which is secured a head 29. In the stop strip 25 is secured a swivel plate 30 having formed therein a smooth hole 31 with which is loosely engaged the reduced outer portion 28 of the screw whereby said screw is loosely engaged with the plate. In the window frame immediately below the swivel plate 30 is secured a fastening plate 32 said plates 30 and 32 being set into the stop strip and frame and secured by fastening screws as shown. In the plate 32 is formed a threaded screw hole 33 which is disposed in line with the hole 31 and is adapted to receive the threaded portion 27 of the screw 26. The portions of the frame and stop strip adjacent to the holes 31 and 33 are recessed as shown to permit the threaded end of the screw 26 to be screwed inwardly or outwardly through the fastening plate 32. By means of the screws 36 and fastening plate 32 it will be readily seen that the stop st-rip may be quickly and easily secured to and removed from the frame and that by providing the swivel plates 30 the screws will be prevented from being removed from the stop strip and thus will always be in position for fastening the stop strip. In order to fasten the sash cord and thus prevent the weight from operating the sash when the latter is supported on the hinges, I provide a stop pin 34 which is inserted between the sash cord pulley and pulley casing as clearly shown in Fig. 1 of the drawings, thus binding the cord against the pulley and holding the cord against the pull of the sash weight.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation ofthe invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention what I claim is:

1. In a hinge of the character described, the combination with two screws and a stop pin in the face of the window sash; of a hinge consisting of two members connected by an upright pivot and whereof one is provided with key-hole slots, the parts being so shaped and disposed that when the round ends of said slots engage said screws in the sash the frame member may be turned on its pivot so that its lower extremity passes over said stop, and means on the window frame for detachably connecting its hinge member therewith.

2. In a window hinge of the character described, the combination with two screws and a stop pin in the face of the sash, and a supporting screw and catch pin in vertical alinement in the frame; of a hinge consisting of two members connected by an upright pivot and whereof one is provided with key-hole slots, the parts being so shaped and disposed that when the round ends of said slots engage the screws in the sash the frame member may be turned on its pivot soV that its lower extremity passes over said stop, a downturned hook at one end of the frame member rovided with an openended notch, the other end of this member being provided with an upright slot, said notch and slot being positioned to simultaneously engage the screw and catch pin in the frame.

3. In a window hinge of the character described, the combination with two screws and a stop pin in the face of the sash, and a headed screw and a headless pin in the frame; of a hinge consisting of two members connected by an upright pivot and whereof one is provided with key-hole slots, the parts being so shaped and disposed that when the round ends of said slots engage the screws in the sash the frame member may be turned on its pivot so that its lower extremity passes over said stop, the frame member including an upright bar having an incline at its upper portion and above the incline a downturned hook with an open-ended notch in its bill and the lower end of the bar having an upright slot, the latter engaging said pin when the notch engages the screw in the frame but said slot disengaging the pin when the incline engages the screw.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MORTON ARTHUR GEORGE.
