HINGE ASSEMBLY Filed M. s, 1948 2 SHEETS-SHEET 2 Patented Mar. 31, 1953 UNITED STATES PATENT OFFICE HINGE ASSEMBLY Paul B. Schwering, Glasgow, Mo. Application November 8, 1948, Serial No. 58,855

upward andoutward swinging movement of the casement to a position within the window frame where the same is freelyswingable'on a vertical axis to and from a fully openposition.

The most important object of the present invention is to provide a hinge for casement type windows having an arm that is, turn, provided with a. pair of oppositely-extending, normally horizontal pintles pivotally secured to the easement and to the window frame, respectively, whereby to permit movement of the easement in the manner just above set forth.

Another important object of the present invention is to provide a hinge assembly of the above-mentioned character wherein the horizontal pintle that is secured to the window frame has aspherical member formed thereon that is rotatably received by a slotted socket on thewindow frame, all to the end that the easement may be raised and swung outwardly from a position within a channel formed in the frame and the casement may thereupon be swung on a vertical axis to an open position as the pintle having the spherical member there on moves in the slot of thefsocket member.

A further object of the present invention is to. provide window structure of the easement type wherein the casement itself includes a frame specially formed to receive a pair of vertically-slidable sashes, the easement frame being formed from metallic strips that are rebent longitudinally to present a pair of side-by-side channels for slidably receiving the sashes.

Other objects of the present invention relate to the way in which the panes of the sashes are providedwith peripheral frames formed to freely slide within the easement channels; the manner in whichthe framework of the casement is as sembledto permit changing of the sashes readily and easily as desired; and the way in which the entire window assembly is formed to present a fireproof, compact construction that is substantially air-tight in the joints, simple and cheap in construction, easily assembled and efficient in operation.

1 Claim. (01.16-163) Many additional, more minor objects will be made clear or become apparent as the following specification progresses, reference being had to the accompanying drawing, wherein:

A window frame broadly designated by the numeral I0 and adapted for insertion within a window opening of a Wall or the like is clearly illustrated in Figs. 1 and 2 of the drawing, said frame ll] being substantially of conventional character. Frame I0 includes a pair of spaced, vertical side members l2, a top bar l4 and a lower bar I6, both of which bars [4 and iii are horizontally disposed between the members l2, thereby presenting a polygonal opening for receivin a casement broadly designated by the numeral [8.

The lower bar I6 of frame 10 is provided with anoutwardly-facing, longitudinal shoulder 20' that extends the entire length thereof, there being an outwardly and downwardly-inclined, flat surface 22 on bar l6 extending from the lowermost edge of the shoulder 20. As hereinafter will become more apparent, through such construction of bar l6,'a channel is formed for receiving the lowermost end of the easement l8.

Casement [8 includes a framework that is formed by a pair of side rails 24 of identical character andhaving the cross sectional contour illustrated in Fig. 4. These side rails 24 are joined by top rail 26 and bottom rail 28, the cross sectional contours whereof are illustrated clearly in Figs. 3 and 5, respectively, of the drawings. 1

The entire framework just mentioned, forming a part of the easement I8, is preferably formed from a bendable, lightweight, metallic material; and the side rails 24 are formed first 3 from an initially flat, elongated strip of metal to present an outermost frame piece 30 having a flat leg 82 and a leg 34 that projects from the outermost edge of leg 32 at an angle and thence into a portion that is spaced from and substantially parallel to the flat leg 82.

As illustrated in Fig. 4 of the drawing, it is the fiat leg 32 of the frame piece 38 that rests upon and abuts against limiting strips 36 forming a part of the window frame l8. Strips 3,6 are of conventional character and are utilized in the usual manner to limit the extent of outward movement of the casement l8 within the frame [8 when casement I8 is in the closed po= sition.

In addition to the frame piece 88, the side rails 24 each include a channel member 88. These channel members 38 are, likewise, formed from a metallic material capable of being bent into the cross sectional contour illustrated in Fig. 4 of the drawing. The initially fiat strip for forming the channel piece 38 is first rebent upon itself on a median, longitudinal line as at 48 to present a dividing partition between a pair of substantially U-shaped channels 42 and 44.

The entire channel member 38 is disposed be tween the legs 82 and 34 of the frame piece 38, with the channels 42 and 44 thereof facing inwardly. The bottom rail 38, as illustrated in Fig. of the drawing, is formed in substantially the same manner as the frame piece 38 of side rails 24 in that the initially flat strip of material forming the same is rebent upon itself to present a flat, straight leg 46 and an angularly-disposed leg 48 that normally bears against the uppermost, longitudinal edge of the shoulder 28 of lower bar member l6 as shown in Fig. 5. An uppermost wall 50 projects inwardly from the normally uppermost edge of leg 46 toward the vertical portion of leg 48 and has a U-shaped channel portion 52 formed therein next adjacent the leg 48. Any suitable means of securing the proximal leg of the channel portion 52,

of wall 58 to the innermost face of leg 48, such as welding, may be used.

The uppermost rail 26 of the frame for casement I8 is provided with a flat leg 54 that rests upon the corresponding strip 36 of frame I 6 when the casement I8 is in the closed position in the manner illustrated in Fig. 3 of the drawing. A downwardly and inwardly-inclined wall 56 projects from the uppermost edge of the leg 54 and merges into a vertical wall 58 that is, in turn, bent horizontally and inwardly toward the leg 54 as at 68. From the horizontal portion 68, a strip of material forming the rail 26 is again bent upwardly to present a vertical partition 62 intermediate the legs 54 and 58. Partition wall 62 has its uppermost edge inclined to conform to the contour of inclined wall 55 to which it is secured by spot weld or the like. A U-shaped member '64 is interposed between the partition 62' and leg 54 adjacent the lowermost edges thereof, one leg of the member 64 being turned laterally as at 65 to present a receiving channel and limiting end for receiving one of the sashes, as will hereinafter appear.

The uppermost rail 28 of the framework for casement [8 has its ends mitered or otherwise formed for connection with the uppermost ends of the side rails 24, but the lowermost rail 26 is joined to the proximal ends of rails 24 through construction illustrated in Fig. 7 of the drawing. The side rails 24 are each provided with a pair 4 of opposed, downwardly-extending, resilient clips 88 designed to be disposed between the legs 46 and 48 thereof, the wall 56 of bottom rail 28 by a cut-away at the ends of the rail 28 for receiving the clips 68.

Detents 70 on the clips 68 and on the bottom rail 28 releasably hold the bottom rail 28 in connective relationship with the side rails 24 through the resilient character of the clips 68. Through the simple and inexpensive interlocking means just described for fastening the bottom rail 28 to the side rails 24 of casement 18, the task of inserting sashes l2 and 14 forming a part of the casement I8 is rendered simple. These sashes l2 and 14 each include a pane 18 of glass or other transparent or translucent material and, accordingly, if either of these panes 76 becomes broken, the sashes 12 or E4 may be entirely removed from the easement l8 for replacement of the broken pane 16.

The sashes, l2 and [4 are of identical character and, in addition to the polygonal pane 18 thereof, includea surrounding framework of the cross sectional contour shown in Figs. 3 to 6, inclusive. Such framework for surrounding the panes 16 is, also, preferably formed from an initially fiat strip of metallic material that is rebent upon itself on a substantially median, longitudinal line to present a fiat leg 18 and an opposed leg that has a portion 88 next adjacent the point of bend that rests flatly against the innermost face of leg 18.

This portion 80 merges into an outwardlyangled portion 82 that, in turn, terminates in a flat leg 84 that is spaced from and is substantially parallel to the leg 18. The pane of the sashes l2 and 14 is inserted between these legs 84 and T8 for tight, clamping relationship therewith. As above indicated, this framework for the panes 16 entirely circumscribes the marginal edge thereof.

The outermost free edge of such framework that includes the rebent portion 88 and the proximal portion of the leg 18 is disposed within the channels 42 and 44, as the case may be, for free, sliding movement therein. The uppermost sash l2, when in the fully closed position at the uppermost end of its path of travel, has its uppermost frame member tightly wedged within the channel 66 of the casement rail 26.-

By the same token, when the lowermost sash 24 is at the lowermost end of its path of travel and, consequently, in the closed position, the framework thereof is tightly wedged Within the channel portion 52 of the bottom casement rail 28.

The proximal, lowermost and uppermost frame members of the sashes l2 and i4, respectively. are spaced apart, as"illustrated' in Fig. 6 of the drawing, and the space therebetween is filled with a pair of strips 86 of identical character and, as shown in Fig. 6, these strips 88 are triangular in cross section for'complementary interengagement when'the two sashes T2 and 74 are both in the closed position.

The entire casement 18, including its polygonal framework and the sashes 12 and M slidably mounted therein, is swingably mounted upon the Window frame l6 through the medium of a pair of hinge assemblies broadly designated by the numeral 88. These assemblieseach include an arm 98, one end whereof has an opening formed therein for receiving a horizontal pintle 82 that, in turn, bridges the distance between the legs of a bifurcated bracket 94.

The bracket 94 is secured directly to the normally innermost face of the side rail 24 of casement l8 in any suitable manner (not shown). The arm 90 is disposed between the furcations of the bracket 94 for free, swinging movement therebetween. As illustrated in Fig. 1 of the drawing, the arm 90 is L-shaped, and the horizontal leg thereof is provided with a ball 96- that is, in turn, disposed within a socket member 98 mounted, upon the innermost face of the proximal side member I2 through the medium of a plurality of screws or the like I00.

The socket member 98 has a horizontal slot I02 formedtherein for clearing the leg of arm 90 having ball 96 thereon; and a coil spring I04 within member 98 is interposed between the frame l0 and the ball 96 for yieldably holding the latter biased against the innermost face of member 98 adjacent slot I02.

Casement I8 is provided with a pair of handles I06 on the upper and lower rails 26 and 28, respectively, thereof; and it is through use of such handles 106 that casement I8 is shifted through its path of travel noW to be described.

Assuming the easement l8 to be in the closed position shown in Figs. 1 and '2 of the drawing, the operator, grasping handles I06, imparts an upward and outward movement to the casement l8 to move the latter from the position shown in full lines in Fig. 2 to the dotted lines of said Fig. 2. Such movement of the casement l8 will shift the bottom rail 28 thereof from the position behind the shoulder 20 upwardly and outwardly to a position where the entire casement i8 is spaced from the limiting strips 36 of frame It.

This movement of casement I8 is made possible by virtue of the fact that arm 90 not only pivots in the bracket 94 but, also, pivots within the socket member 98 by virtue of the freely rotatable ball 96 therein.

After the easement 18 has been moved to the position shown by dotted lines in Fig. 2, the entire casement may be swung on a vertical axis to a fully open position. When such swinging action is imparted to the casement l8, that leg of the arm 90 that is secured to the casement l8 will rotate on around a vertical axis; and the leg of the arm 90 having ball 96 thereon will freely swing within the slot I02 of socket member 98.

From the foregoing, it is clear that a window construction having many advantages has been presented, not only from the standpoint of simplicity of manufacture, cheapness and durability, but from the standpoint of presenting a relatively air-tight Window itself. When the casement i8 moved to the closed position, the same will be wedged in place because of the fact that the lowermost, substantially triangular-shaped frame rail thereof is fitted between the limiting strips 36 and the shoulder 20 of bottom member I6.

This channel-like receiving portion of the frame ill for the easement l8 serves to hold the entire casement i8 tightly against the limiting strips 36 to prevent entrance of air, moisture and other elements.

Since, as above made clear, the entire casement l8 can be made from a fireproof structure and from relatively light material, many advantages will arise through its use. As far as I am aware, the hinge assemblies for mounting the casement [8 within the window frame [0 have not heretofore been provided; and it is through the use of such hinge assemblies that the novel movement of the casement I8 is made possible and thereby the air-tight assembly thereof is accomplished.

Structures of the character forming the subject matter hereof are obviously capable of many changes and modifications; and it is, therefore, manifest that such deviations from the single embodiment herein set forth as fairly come within the scope of the appended claim are contemplated hereby.

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

A hinge assembly comprising structure having a socket therein and a slot registering with the socket; means on the structure adapting the same for mounting on a support; a ball rotatably mounted in said socket; an L-shaped arm having a first elongated leg extending through said slot and a second elongated leg provided with a hole, said ball being secured to one end of the first leg; a bifurcated bracket embracing a portion of said second leg and adapted for securement to a member to be mounted on the support; and an elongated pintle on the bracket and passing through said hole for swingably attaching the arm to the bracket, the longitudinal axes of the pintle and of the first leg being substantially parallel.
