O V BY k/ 27 1| ATTORNEY Patented Feb. 24, 1953 UNITED STATES PATENT OFFICE LATCHING DEVICE FOR STORM WINDOWS Application August 15, 1950, Serial No. 179,515

3 Claims.

This invention relates to storm windows or the like in which a closure member is mounted so as to be slidable between opposed channel members, and it has for its object, the provision of a new and improved form and arrangement of parts by which a closure member may be hel very strongly in centered position between the channel members and may be looked very securely in its normal lowermost position or in any other selected adjusted position longitudinally of said channel members. It is one of the objects of my invention to provide an improved structure of this type comprising channel members formed of sheet metal and secured in fixed position, extending vertically at opposite sides of a window opening, with my improved holding means mounted on the sash or other closure member at one side edge portion thereof and constructed and arranged so as to have strong gripping engagement with the adjacent channel member.

It is one of the objects of my invention to provide highly effective means for securing my improved holding devices strongly in the desired adjusted position transversely of the sash or other closure member at opposite sides thereof, so as to have effective cooperation with the channel members for gripping purposes and also for insuring that the closure member shall provide the desired degree of completeness of closure of the window space between the vertically disposed side channel members with the necessity for precision fitting of the parts with respect to each other.

It is another object of my invention to provide an improved form of releasable device for pressing the edge portion of a closure member facewise against one of the flanges of a channel member in which said closure member is mounted, such device being adapted preferably to be released readily and quickly whenever a change in position of the closure member is desired.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawing which, by Way of illustration, shows a preferred embodiment of the present invention and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle. Other embodiments of the invention embodying the same or equivalent principle may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

In the drawing:

Fig. 9 is an enlarged detail view of the lower right-hand corner of the upper sash, as shown in Fig. 1, in position in a, channel member and showing the means for holding the sash releasably in its raised position.

Referring now to the several figures of the drawing, in which corresponding parts are indicated by the same reference characters, It] and l I indicate, respectively, the lower and upper sash members of a storm window assembly of the typ disclosed by my earlier application, Serial No. 109,470, filed August 10, 1949, in which each sash member comprises four bars I2 connected together by corner brackets l3 in the form of angles, as shown in Fig. 2. Each of the bars [2 is made of metal in the form as shown in Fig. 6, having a deep groove M in its inner edge for the reception of the edge portion of a pane of glass, and having an undercut groove [5 in its face for reception of the arms of the corner brackets i3. Set screws [6 in suitable screw threaded openings in the corner brackets l3 serve, when tightened, to draw the arms of the corner brackets into strong gripping engagement with the ribs ii at opposite sides of the undercut grooves I5. With two bars l2 having mitered ends, as shown in Fig. 2, and with the arms of a corner bracket [3 positioned in the undercut grooves I5, two of said set screws l6 are adapted to provide a very strong connection between th bars. With four of such bars 12, connected by four corner brackets 3 so as to extend about a glass pane I8 and the usual resilient cushioning channel I8C, a very strong, rigid sash structure is provided.

In the construction as shown in Fig. 1, the lower sash It is slidably mounted between two channel members I9 formed of sheet metal and secured rigidly in position between the blind stops at opposite sides of a window opening, as described in my Patent No. 2,514,349, patented July 4, 1950, and the upper sash II] is slidably mounted between two channel members formed of sheet metal and secured rigidly in position in the blind eats at opposite sides of said window opening. A

channel member 2I similar to the channel members 26 is provided across the top of the window opening in position to receive the upper sash II when moved to its topmost position, and a channel member 22 is provided at the lower end of the window opening to receive the lower edge of the sash I0.

As is best shown in Fig. 9, the upper sash II is held in its raised position in the channel members 20 by means of clips 23 pivotally mounted on the inner faces of the channel members by pivot pins or rivets 24. Said clips 23 are so p0- sitioned that they engage the bottom face of the upper sash member when turned into operative position for supporting the sash, and are readily movable out of supporting position when it is desired to lower the sash from its normal raised position, as when the sash is to be removed from the channel members. This arrangement as here described is substantially in accordance with the disclosures of my prior application, Serial No. 35,461, filed June 26, 1948, and now abandoned. The arrangement as shown in Fig. 3, comprising light leaf springs 25 mounted in position by means of rivets 23 on the inner faces of the webs of the channel members I9, so as to apply pressure on the sash IO'for centering it between the channels I9, is also illustrated by my said prior application, Serial No. 35,461, filed June 26, 1948, and now abandoned.

My improved means for pressing the lower sash II! facewise against the face of one of the flanges of the said channel member I9, in which the sash is slidably mounted, comprises two

metal bars

21 and 28 adjustably mounted on the transversely extending bottom bar I2 of such lower sash II]. The bar 28 is relatively thin and flexible, and as shown in Fig. 3, the end portion of the bar 28 is bent at an angle so as to fit snugly against the end of the bar 2'! for holding said bars from swinging movement with respect to each other on the screw 29 by which said bars are secured in position.

In my improved construction, the screw 29 is mounted by means of screw threads in a block or supporting member 30 slidably mounted in the undercut groove I5 of the bottom bar of the lower sash I0. The arrangement is such that when the screw 29 is tightened, the block 30 and the

bars

21 and 28 are brought into tight gripping engagement with the ribs I! of the bar I2, so as to hold the block and said

bars

21 and 28 strongly in adjusted position to which they have been moved. As will be appreciated from an inspection of Fig. 3, the block 3!] may be adjusted to such position along the bottom bar I2 of the sash ID as to insure that the bar 21 shall have the desired position with respect to the side bar I2 of the sash. As is shown in Fig. 3, the end portions of the

bars

21 and 28 are positioned at opposite faces of the outer flange of the channel member I9, with the bar 28 extending only slightly beyond the end of the bar 21. Means are provided in my improved construction for pressing the end portions of the

bars

21 and 28 strongly toward each other with a clamping action for applying the desired pressure on the flange portion of the channel member. These means comprise an arm 3I connected with the bar 21 at right angles thereto, being preferably formed integrally with such bar 27. On the outer end of said arm 3|, I have mounted a cam lever 32 pivotally supported in position by means of a rivet 33. When such lever 32 stands in horizontal position, as shown in Fig. 5, the

bars

23 and 21 are adapted to move into ubstantially spaced relationship to each other so as to stand free of the flange of the channel I9. When such member is swung upwardly into the locked position as shown in Fig. 4, however, the face of the lever by a camming action forces the bars 2'! and 28 toward each other into tight gripping relationship to the flange of the channel I9. The construction is such that the lever 32 is held releasably in a locking position by its frictional engagement with the face of the bar 28. Moreover, the thin strip or bar 28 is so arranged that the camming action of the member 32 is exerted on the strip 28, thereby to avoid damage to or objectionable roughening of the face of the channel I9.

With the screw 29 holding the block 36 in desired adjusted position, transversely of the sash so as to hold the bars 2'! and 23 in their effective working positions, as shown in Fig. 3, when the lever 32 is standing in its raised locking position, the sash III is held firmly in adjusted position to which it has been moved. When the levers 32 are swung downwardly to their lowered unlocked positions, such levers 32 serve as handles whereby the sash I0 can be moved very easily to the desired raised position for ventilation or for removal of the sash from the channels I9.

By the use of my improved construction, a very eifective and convenient control is provided for the sash, and the latch arrangement i of such a character that it may readily be put into position on the sash, and when so positioned is effective both as a handle and a latch. Moreover, the present latch structure is effective to accomplish its latching or securing operation without damage to the face of the channel I9. The structure is readily produced without difficult manufacturing operations, and is highly effective and of such strength and durability as to be reliable for use for many years without replacement or repair.

Thus, while I have illustrated and described the preferred embodiment of my invention, it is to be understood that this is capable of variation and modification, and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and al-- terations as fall within the purview of the following claims.

I claim:

1. A closure structure comprising in combination an elongated member formed of sheet metal in the form of a channel mounted in fixed vertical position in a window opening, a closure member having one side edge portion slidably mounted in said channel member, the closure member having a bottom bar, a supporting member mounted in the bottom bar, means allowing adjustment of the supporting member in the bottom bar, inner and outer metal bars carried by the supporting member and held thereon by the adjustment means, the metal bars respectively engaging the inside and outside faces of one of the flanges of the channel member, and manually operable means acting between the metal bars for pressing the outer bar strongly toward the flange to draw the closure member into locking engagement with the flange.
