' WINDOW BRACKET Filed Sept. 6, 1941 WILLIAM H. SCHMIT Patented May 9, 1944 UNITED STATES OFFICE 9 Claims.

My invention relates to an improvement in window brackets, wherein it is desired to provide a fastener suitable for use in combination with storm sashes, casement windows, basement windows, and the like.

It is the object of the present invention to provide a storm sash fastener which is removably connected at each end. Such a construction has various decided advantages over fasteners which are removable at one end only. I

It is a feature of my invention to provide a means of disconnecting the bracket in such a way that the window may be quickly opened up in case of an emergency. At the salne time, itis necessary that the fasteners be so constructed that they will not become accidentally disengaged. It is a feature of my invention that with my construction, the window bracket may be en tirely removed in an extremely short period of time and at the same time, the construction is such that accidental disengagement is virtually impossible.

It is a feature of the preferred form of my invention that the fasteners or brackets may be entirely removed by swinging the pivoted arms forming the body of the fasteners in unison to a predetermined pivoted position, in' pressing the spread arms of the bracket together under spring tension, and in pivoting the squeezed arms on an axis at substantially right angles to the normal pivotal axis of rotation of the arms in order to remove the bracket from place. means, the brackets may be entirely removed from their respective stile plates, leaving the window free to pivot open to any desired extent.

It is a further object of my invention to pro vide a window bracket or fastener which is equipped with two types of stile plates, one of which is designed for use in connecting one arm of the window bracket with a surface extending substantially parallel to the arm, and the other bracket of which is used to connect the other arm of the fastener to a surface extending on a plane at substantially right angles to the plane through the other bracket arm. Two of the latter brackets are used in the combination. With this arrangement, my fastener may be used to connect a casement window to a frame, to connect a storm sash to a window frame, or a basement window to its frame, the proper stile plates being selected from the assortment of three stile plates furnished with each such bracket. Thus my fastener is just as adaptable for windows pivoted on vertical axis as for windows pivoted on horizontal'axis.

These and other objects and novel features of invention will be more clearly and fully set forth in the following specification and claims.

In the drawing forming a part of my specific'a tion:

Figure 12 is an elevation view of the other arm of the bracket shown in Figure 10 and its relation with its respective stile plate just before'attachment thereof.

The storm window bracket or fastener A in-' cludes an arm ill and a second arm I l pivoted together and connected by means of a pivot bolt E2 or the like. The arms Ill and H are preferably provided with enlarged ends l3 and I re spectively through which the pivot bolt I 2 extends and washers of friction creating mate rial are inserted betweenthe heads l3 and" 14 and between the heads of the bolt l2 and the adjacent enlarged end I-i in order to resist p'iv otal movement between the arms ill and H. These friction washers l5 hold the" pivot arms l9 and H in any set adjusted position, and the friction may be regulated by adjustment of the nut on the bolt l2. The end of the arm H extends beyond the enlarged head l4 and is bent at right angles to form a flange or lug Hi which limits the pivotal movement of 'the'ar'ms' so that the arms 10 and H cannot move ln'to' alignment. This fact is true because the flange 16 on the arm ll strikes the body of the arm I 0 adjacent the head I3 as shown in Figure l of the drawing to limit pivotal movement in this direction.

An ear IT is provided on the arm II which extends over the arm I5 and is provided with a downwardly extending flange I3 to limit the spreading of the arms I and II apart. The arms I3 and II are offset at 20 and 2| respectively so as to spread the free ends of the arms I!) and II, and these arms are urged apart under spring tension.

The ear I! acts as a locking lug in one pivotal position of the arms I and I I as will be later described.

The free ends 22 and 23 of the arms I53 and II are enlarged as best noted in Figure 5 of the drawing, and are provided with a locking device 24 by means of which the arms are disengageably secured to their respective stile plates 25 and 25. The locking lugs 24 are formed as best illustrated in Figure 5 of the drawing, being provided with a cylindrical bearing portion 21 and a flat T-shaped head 23. Each of the locking devices 24 is designed to fit through a suitable recess 30 in the respective stile plates 25 and 26. Each recess 33 includes a circular opening having opposed slots 3i extending radially therefrom as illustrated in Figures 6 and '7 of the drawing. The T-shaped head 29 may extend through any of the recesses 30 when the T-shaped head 29 is in proper pivoted relation with the opening, and once the head 29 has projected through the opening, the head provides shoulders 32 to engage on the opposite side of the stile plate to lock the bracket arms in place,

In the preferred form of construction, the opposed slots 35 extend longitudinally of the stile plates 25 and 26 while the locking means 24 is formed with the T-shaped head extending transversely with respect to the arms Hi and I I. Thus in every position of the bracket arms I3 and II, except the position shown in Figures 3 and 4 of the drawing, the T-shaped head 29 will not coincide with the openings 33. For example, in the open position shown in Figure 1 of the drawing, the locking heads 24 will not align with the openings in the stile plates 25 and 25, and in this position the fastener or bracket A may not be removed. This is also true of the position shown in Figure 2 of the drawing, as in this construction the heads 29 of the locking means 24 extend at right angles to the slots or notches 3|. When the bracket arms have been pivoted into the position shown in Figures 3 and 4 of the drawing, however, in which position the arms extend outwardly at substantially right angles from the window, the heads 29 align with the notches (H and the brackets may be removed.

Due to the normal outward spring tension of I the arms I5 and II, the brackets will not become accidentally disengaged even when in the position shown in Figures 3 and 4. If it is desired to remove the brackets. however, when the arms are in this position, the arms are squeezed together as indicated by the position shown in dotted outline in Figure 3, at which time the locking means 24 of the arm II is removed from the recess 30 in the stile plate 26. By opening the window sash 25 while the bracket arms are held in this position, the arms may be swung out of contact with the stile plate 25 to permit removal of the locking means 24 on the arm I0 from the stile plate 25. A simpler manner of removing the fasteners or brackets, however, is to pivot the arms ID and II in the manner shown in Figure 4 of the drawing, thus removing the locking means 24 from the stile plate 25. Thus by merely pulling the two brackets or fasteners into a substantially horizontal position, squeezing the arms of each fastener together, and pivoting the same inwardly, both fasteners may be removed in an extremely short period of time.

As is common in brackets of this general type, the ears I! provide a means of locking the storm sash 33 to the window frame 34. From an observation of Figure 1 of the drawing, it will be clear that when the storm window has been closed, the arms I0 and II will assume parallel relationship in the manner illustrated in Figure 2. As the arms I0 and I I are of the same length, these arms may then be pivoted through until the body of the arms I0 and II is above the stile plates 25 and 26. In this position the ear I! prevents outward movement of the arm Illwith respect to the arm II, thus locking the storm sash in closed position.

It will be noted that the stile plate 25 has its opening 30 in a central offset portion 34 so that the locking head 24 may extend between this central ofiset portion and the body of the window frame 34.

In the construction shown in Figures 8 and 9 of the drawing, a window fastener or bracket B is designed to be disconnected at either end from corresponding stile plates. In the fastener B I provide a pair of arms 35 and 36 having enlarged connecting ends connected by means of a pivot bolt 31. Friction washers 39 are positioned between the arms, and the arm 36 is provided with an extension 40 terminating in a second enlarged head M which is parallel to and spaced from the head of the arm 36. The extension or connecting portion 40 acts in the same manner as the lug or flange l6 of the fastener A to prevent the arms 35 and 36 from moving into alignment. Thus in any position of the storm window or the like to which the bracket is attached, the window may be closed without first moving the arms 35 and 36 out of alignment.

A spring plate 42 is connected to each of the arms 35 and 35 by means of a pair of ears 43 which encircle the arm at one end of the plate. The plates 42 are provided with additional oppositely disposed ears 44 at the other end thereof which loosely encircle the arms 35 and 35. A pair of opposed notches 45 on each arm 35 and 35 provide shoulders to engage the ears on the plate 42 when this plate is in one extreme position, as illustrated in Figures 8 and 9 on the ar'm 35. When moved to the other extreme positionas illustrated in Figure 8 on the arm 35, the ears on the plate 42 ride over the ends of the notches 45, the ears 43 springing sufiiciently so that this action may take place. Each of the spring plates 42 is provided with a notch 43 to engage about a pivot pin in a manner which will be now described.

The stile plates to which the arms 35 and are attached may be of the type generally indicated by the numeral 41 or may be of a type indicated by the numeral 49. The stile plate 41 is right angular in shape, having an attaching flange 50 drilled to accommodate screws or fastenin means, and a flange 5| from which a pivot pin 52 projects. An encircling groove 53 is provided on the pin 52 to accommodate the bifurcated end of the associated plate 42, the notch 45 being of a width to accommodate the small diameter portion of the pin 52 at the base of the groove 53, but being too narrow to fit about the entire body of the pin 53. Thus when the arm 35 is attached to the stile-plate 41 the pin 52-extends through the circular opening 54- in the free end of the arm 35, and the spring plate 42 is moved upwardly so that the birfurcatedend thereof engages in the groove 53 to prevent disengagement of the arm 35 and the pin.

The stile plate it is provided with aligned attaching ends 55 through which holes are drilled to accommodate screws or other'fasteni'ng-means and an offset central portion 56 accommodating a pivot pin 57. As shown in Figure 9 i the drawing, the pivot pin is provided withan annular groove 59 in which the bifurcated end of the spring plate 62 associated therewith may engage. Thus when in the position shown infull outline in Figure 9, the spring plate holds the bracket arm to the stile plateagainst accidental disengagement therefrom, but permits free pivoting of the bracket arm with respect to the stile-plate.

The fastener C illustrated in Figures 10, 11,

and 12 of the drawing also may be'disconnected rom its associated stile plates S13 and (it when it is so desired. The fastener or bracket 0 comprises a pair of arms 62 and $3 having enlarged ends which are connected by an adjusting bolt B4. Friction washers t5 are'interposed between the arms 62 and 63 so as to create friction tending to hold the arms in any set adjusted relation. A lug E56 on one of the arms 62 prevents the arms 62 and 53 from moving into alignment to facilitate the closing of the window from wide open position. Each of the arms 62 and 63 are provided with enlarged circular heads ii and 59, respectively, having circular openings it and H therein to accommodate the pivot pin on the stile plates 65.} and '5 l.

The stile plate 69 is provided with an attaching flange i2 drilled to accommodate screws or other fastening means A flange 13 extends at substantially right angles to the flange Gil and is provided with pivot pin "Ed extending at substantially right angles thereto. A flange i5 extends upwardly from the plate 69 substantially parallel to the flange i3 and is provided with a tip end 16 which extends toward the pin it and terminates in spaced relation thereto. The roundedflat end 67 of the arm 62 is provided with a notch 11 through which the tip end it of the flange lamay pass. As shown in Figure 11 of the drawing, the flange E5 is spaced from the flange i3 sufficiently to permit the arm 652 to be positioned between these flanges. In any angularposition of the arm $2 other than the position in which the tip end 75 may fit through the notch H, the tip end 16 will engage over the face of the rounded end of the arm 62 and prevent its disengagement therefrom. In one angular position of the arm 62 with respect to the stile plate 69, however, the arm 62 may be engaged or disengaged from the pin 14.

A stile plate ti includes a pair of aligned attaching ends 19 which are drilled to accommodate screws or other attaching means. A pin 8| projects outwardly from the central portion of the plate 8! to fit into the circular opening H of the arm 53. An ear 82 projects forwardly from the central portion of the stile plate 6! and includes a flange G3 which is bent substantially parallel to the plate 6! and in spaced relation thereto. As seen in Figure 12 of the drawing, the flange 83 is spaced from the central portion of plate 6! sufiiciently to permit the arm 63 to extend between this flange and the plate 6 l.

A notch 84 is provided in a rounded head 63 to accommodate the flange 83. When the arm 63 is in one specific angular relation with respect to the stile plate 6!, the arm 63 may slip onto or off from the pin 8!. In any other angular position of the rod 63, the flange 83 overlies the face of the head 69 of the arm 63, and holds the arm 63 engaged thereto.

The notches T! and 86 may be so positioned that one of the arms may be detached whiie the bracket is in one angular position and the other of the arms may be detached in another angular position. If desired, these angular positions may coincide so that both ends of the bracket may be detached at the same time. It is preferred, however, in this construction to have one of the brackets detachable in one angular position and then by pivoting the bracket slightly, the other end or other arm may be removed.

In packaging the present device, I prefer to include a pair of brackets such as A, B, or C and to include with these brackets one pair of stile plates such as is shown in Figures 7, 9 or 12, and to furnish two sets of stile plates of the type shown in Figure 6 or 11 and shown at the lefthand side of Figure 8. In other words, for each bracket A I provide one stile plate 26'and two stile plates 25. For the bracket B I provide one stile plate such as 49 and two stile plates such as 41. With the bracket C I provide one stile plate 6| and two stile plates 68. The stile plates are designed to flt on either end of the bracket and by providing extra stile plates of the type described, both ends of the bracket may be provided with right angular brackets to engage surfaces at right angles to the plane of operation of the bracket arms. My bracket is thus made suitable for use for an extremely great combination of cases, and may fit any one of a great number of installations.

It will be seen that with the type of construction shown in Figures 1 through 7 of the drawing, it is only necessary to pivot the bracket arms in unison to a horizontal position and to pivot the pivotally connected ends of the brackets inwardly of the Window in order to remove the brackets. Thus in a simple movement, the brackets may be detached in an emergency or when it is desired. The brackets are not supported either by the window sash or by the window frame during the period they are not in use, and therefore the windows may be handled without danger of having the brackets project through the glass panes of an additional sash to break the same.

While I have discussed the bracket as being particularly designed for use in conjunction with pivoted windows of one type or another, it is obvious that the brackets may be similarly used on doors or closures of various types. Thus when I mention pivoted windows in the claims, I desire to have it understood that doors or other pivoted closures could be similarly connected. Furthermore, while I have discussed pivot pin connections in which one part of a bracket is secured to a stile plate by means of a pivot pin connection which fits into a suitable recess in the other element, it is obvious that pivot pins could be on either of the elements and the cooperating recess in the other of these elements.

In accordance with the patent statutes, I have described the principles of construction and operation of my window bracket; and while I have endeavored to set forth the best embodiments thereof, I desire to have it understood that these are only illustrative of a means of carrying out my invention and that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
