One of th'ema'ihfunctionsfo'f af'rc'urtai'n stretcher is totstretch the curtainitoias near its originali` forintasipossibleVand-lmost curtains whiler vanying sizeuaie of..rectangularwform so t tf-.ii is imperative. that, thestretchenf traine have:k 'ac-- curat'e 1corners and. be` constructed-Fin man1- n'eie asly t'ov not: only.A permit. accurate adjustment of width and length to accommodate the Wide range of sizes, but also to assure parallelism of side and end edges. In order that this result may be obtained, the corner plate embodying the present invention has been developed. According to this invention, instead of the usual nat metal corner plate, the corner plate is provided with flanges, its outer edges bent at ninety degrees tothe body of the plate and at ninety degrecs to each other to provide a means for retaining the upper horizontal bar of the stretcher and the abutting upper end of a side or end bar of the stretcher in accurate right angular relationship with each other, thus assuring a rectangular or square corner. Also in order to permit ready removability and assembly of these parts relative to each other, the tting which is anchored to the top bar has a slot in its vertical leg which is slipped over a bolt on the vertically disposed end frame member and then clamped to this member -by a nut on the bolt; the slot being so spaced from the flanged side of said vertical leg that it precludes any appreciable side movement of said end frame member which would Vhave the tendency of changing the right angular Fig. 3 is an enlarged front elevational view of a corner plate embodying the invention;
Fig` 4 is a perspective view of the corner plate. Referring to the drawings, the upper portion of a curtain stretcher has been shown including the top bar 5, side or end bars 6, vertical center bar 1, and a vertical adjusting 'bar 8. The bottom bar which is clamped to end bars 6 and to the telelineA 01- zee-634i V bars 'I and 8 has not been shown vbut.:is;show1l1 ishown. Thefbottoinrbar, top sbar; 5; .leftshandfend bar 6, and the-adiustirrgfbar' araprovidedwith g onv which; portions? off. the;I damp curtains rf'iabnics-arefimpaledf to-.ist'retch-` the; interiorv litin'thismondition: until dr-ied:
The: presenti. invention is directed totA the core` nenlstcuoture by.-l whichthe: endsl of: the top 5r ane. 'secured in; accurate; right; anglech relaf: tionship with the abutting top end 9 of the end bars 6. For this purpose a corner plate ID, shown in detail in Figs. 2 to 4, is secured to the ends of the top bar 5 and is removably clamped to the upper end of the abutting end bar.
The corner plate l0 is formed of a sheet metal stamping having a flat body portion formed to provide a top leg I I and a vertical or side leg I2, holes I3 beingV punched in the top leg to receive rivets I4 by which said plate is iixed to the back of the top bar 5. The top leg Il has a top edge flange I5 bent at right angles to the body and at right angles to a side edge ange I6 also bent at right angles to the body, so that when the top bar 5 has its top and end arranged in abutting relation with the flanges I5 and I6 and secured by the rivets I4, the flange I6 will present a true right angled metal extension of the top bar, so that when the top of the end bar 6 abuts the lower horizontal edge of the top bar 5 and the outer side of said bar 6 abuts that portion of the flange I6 depending from the top bar, the bars 5 and 6 will be positioned in accurate right angular relationship, and in order to maintain this relationship and yet permit ready assembly and disassembly of these parts of the stretcher frame, the side leg has a slot Il formed in the lower end thereof which extends parallel to the ange I6 and spaced therefrom the same distance as the hole I8 in the bar 6 for a clamping bolt I9 is spaced from said flange I6, so that when the top bar is positioned in abutting angular relationship with said end bar and the slotted portion of said leg I2 is slipped over said bolt, the parts may be secured together by a wing nut 20 which clamps the plate I0 between it and the back side of the upper end portion of the end bar 5, the slot I'l permitting this assembly without the necessity of removing the nut 2U.
Thus when the top bar 5 is clamped at its opposite ends to the upper ends of the end bars 5, these end bars will be held in accurate right angular relationship with the top bar.
The above construction has the following advantages: the rectangular ange l5 assures positive alinement to and with the top bar to which it is attached. The plate is formed in accurate dies so that the anges |`5 and I6 are at all times at right angles to each other. The corner plates IB are securely fastened to the top bar 5 by the rivets I4. The removable end mem'- bers 6 are attached to the securely fastened end plates by the bolts I9 and wing nuts 20 and are supported by the other leg l2 of said plates in abutting relation with its ange, thus preventing shifting of the corner parts which would result in an angle of more than ninety degrees. The location of the slot l1, engaging the bolt and wing nut assembly of the removable end bar is such as to Vpermit abutment of the end of the` bar 6 with the top bar 5 at the same time preventing shifting to an angle of less than ninety degrees and the slot obviates the disassembly of the nut from the bolt.
I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
What I claim as my invention is:
1. In a curtain stretcher having a top frame bar and side end frame bars extending at angles to each other, said end bars abutting the lower sides of said top bar at the ends thereof, a iitting for securing each of said end bars to the top bar in right angular abutting clamped relation, comprising a plate having a top leg portion anchored to the back of said top bar and a side leg portion projecting beyond the lower .portion of said topbar, each of said leg portions having flanges extending at right angles to the plate and at right angles to each other, the flange on said top leg portion abutting the upper side of said top bar and the flange on the other leg portion abutting the end of said top bar and the adjacent side of said end bar, and a bolt extending through the upper end portion of said end bar and provided With a nut for clamping the depending portion of said side leg portion to said end bar.
2. The structure as dened in claim 1 wherein the lower end of the side leg portion is provided with aY slot to receive said bolt and spaced the same distance from the side flange of said plate as said bolt is spaced from said iiange.
