Patented Aug. 16, 1921.
Application filed April 15, 1920. Serial No. 374,183.
To all whom it may concern:
Be it known that I, PATRICK J. HEALEY, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have made and 1nvented certain new and useful Improvements in Metal Sashes, of which the follow in is a specification.
if invention relates to metal sash, for winc ow frames, door frames, partitions and for other uses for which the same may be ap licable.
etal sashes are usually constructed w1th vertical and horizontal bars, which are substantially T-shaped in cross section as the same is particularly adapted for this use, due first to its inherent rigidness and strength, both with regard to shearing forces and bending moments, and second, due to the pocket formed between the confronting flanges and webs of adjacent horizontal and vertical bars and into whlch the glass panes are placed and held. In the yarious metal sashes, with which I am famlliar, the joint between the horizontal and vertical bars is accomplished by cutting away or notching both the web and flange of one of the bars. This notching or cutting away of the flanges of the cross bars tends to materially weaken the sash, part cularly with regard to its resistance to bending moments, such as are caused by snow or high wind pressures, and in fact this weakening has in some instances been the direct cause of failure of a sash. In other instances, while the notching of the flange has not been sufficient to cause the failure of the sash, yet it has embodied within the sash, an altogether undesirable degree of flexibility, due to the weakening of the bars with respect to bending.
It is accordingly an object of my invention to provide a metal sash or frame joint wherein the original strength of the bars with regard to resistance to bending moments is preserved and the metal which is cut away for the protrusion of one bar through the other lies entirely within the web of the bar and is located approximately central with respect to the neutral axis thereof.
A further object is to accomplish the aforementioned ends in a simple and expeditious manner and to provide a sash, which when assembled will have a high resistance to bending and sufficient resistance with respect to shearing forces. Further, to provide a sash which may be economically manufactured and with the crossing bars so formed as to be rigidly locked against all relative movement.
W1th the foregoing and other objects in view, which will appear as the description proceeds, my invention resides in the novel metal sash illustrated in the accompanying drawings and described in the present specification, and in the novel combination and arrangement of parts and in the details of construction as hereinafter described and clalmed, wherein it is to be understood that changes may be made within the scope of what is claimed without departing from the spirit of the invention.
The preferred embodiment of my invention is disclosed in the accompanying drawings, wherein Figure l is a view in plan of a portion of a window embodying the novel features of my invention;
Fig. 2 is a view in top plan of the frame oin 3 is a bottom plan view of the same;
Flg. 4 is a view in transverse section taken on the line H of Fig. 2;
Fig. 5 is a view in transverse section taken on the line 5-5 of Fig. 2;
Fig. 6 is a view in transverse section taken on the line 6-6 of Fig. 4;
Fig. 7 is a view in side elevation of one of the crossing bars; and
Fig. 8 is a fragmental View in perspective of a bar, illustrating the manner in which the web is cut away to receive the web and flange of the cross bar therethrough and also illustrating the cutting and bending of the rib with which the second cross bar is provided.
Referring specifically to the several views, wherein corresponding parts are designated by similar reference numerals throu hout, t e metal sash is composed of a num er of crossin bars A and B. Each bar A is preferably formed with a web 10, and flange 11, the latter being provided along its side edges with the inwardly projecting ribs 12. The web 10 is provided with a T-shaped slot 13 therein, the head of which lies along the inner surface of the flan e 11. The ribs 12 adjacent the T-shaped s ot of the web are provided with the outwardly and downwardly bent wings 14, formed by slitting or cutting the ribs 12 and bending the free intermediate ortions into the general plane of the flange 1, the distance between the shts being equal-to the width of the flange of the cross bar B as hereinafter descrlbed.
The cross bar B is in turn, preferably formed with a web 15, and flange 16, the former being provided at its lower edge with a restricted notch 17, equal in width to the thickness of the web 10 of the cross Y cross bar B, thus securely locking the bars in their registered position and holding them rigidly against movement in any direction.
The center of area of the T-slots 13 lies al roximately on the neutral axis of the ar A, so that the slotting of the bars A, necessary for the protruding of one bar through the other will have a minimum effect upon the strength of the cross bars with respect to resistance to bending moments.
From the'foregoing it will be observed that a strong and rigid frame or metal sash is obtained, the bars being securely locked again-st longitudinal or transverse shifting and securely held against distortion. F urther, the slots lying entirely within the web of the cross bar prevents undue weakening or. undue flexibleness of the frame or sash.
Having thus described my invention, what I claim is:-
1. A metal sash comprising crossing bars, each formed with a web and a flange, one of said bars having ribs lying along the edges thereof and with a slot lying wholly within the web of said bar and adapted to receive the other cross bar therethrough, the ribs of said bar adjacent said slot notched and bent outward to form tongues lying in the general plane of the flange, the second cross bar provided with a notch in the free edge of its web and adapted to engage the web at the lower extremity of the slot of the first mentioned bar, and the flange of the second mentioned bar adapted to seat within the notches formed by the tongues of the first mentioned bar.
2. A metal sash comprisingcrossing bars, formed with a web and a flange, the joint between the bars characterized by one bar be ng provided with a slot lying wholly within its web, with the head portion of the slot extending along the inner surface of the flange of the first mentioned bar, and provided with notches adjacent the aforementioned slotand the second bar provided with a notch at the free edge of its web and adapted to receive the web of the first mentioned bar therein, the second mentioned bar extending through the slot in the first mentioned bar with the flange thereof lying within the notches of said ribs and held against movement thereby.-
3. metal sash or frame formed of substantially T-shaped bars, having joints between the crossing bars, characterized by providing a substantially T-shaped slot in the web of one bar with the center of area thereof lying approximately on the neutral axis of the bar and with thehead of the slot extending along the inner surface of the flange of the bar, ribs extending along the flange of the first mentioned bar and provided with notches adjacent the aforementioned slot with the resulting tongues bent into the general plane of the flange, and the second bar extending through the said slot and held against movement by the side walls of the notches in the rib andprovided at the free edge of its web with a notch receiving the web adjacent the slot of the first mentioned bar therein and the said tongues bent into engagement with the top of the second mentioned bar.
