Application filedFebruary 18, 1907.-

To all 'uihom it my concern: 1

7 Be -i known hat I, CnAnLns C. ARM- STRONG, a citizen of the United States, residing at'Marysville, Dhimhave invented certam new and useful Im rovements in Frames for Holding Wire-Clot or other Fabric, of which the followin is a specification;

My invention re ates to frames for holding screen cloth for window screens,'or for like pturposes, andis an im rovement over the ame shown in Letters atent of the United States granted'to me Jul 17, 1906, #825952. In sai patent I disclose a main frame member and a clamping member having ivotal connection therewith, the said mem er's having clamping inner portions between which the screen cloth lies and whichwhen the clamping member is swung downwardly into position to hold the screen clamps the same between itself and the frame member, and as a specific feature of the frame disclosed in the saidpatent, Iemployed means for securing the said members in clamping relation, said means consisting, in the embodi ment of my invention illustrated, of screws.

My present improvements relate to the arrangement. and relative construction of the parts whereby I. am enabled to dispense with this specific means of holding the clamping members together, and. instead of employing any holding devices ,-I simply s ring the parts to ether in which'position t ey are maintamed by the frictional contact between them. 7 I

The invention consists in the features hereparticularly pointed out in the claims. I

In the accom anying drawing,-Figure 1 is aplan view 0 the members composing the frame. Fig. 2 is a cross sectional view of the.

same.

In these drawings, 3 indicates the main frame member formed with a channel portion 4 and aturned-over or rolled edge 5. This member I firleferably make of metal, though I. do not it myself in this respect, as it may be made of wood or other material, and at an intermediate part of this member I form a rib 6 projecting mwardlyin respect to the said members, and 'where,-as in the form' illustrated herein, I make the main member of metal, this rib is formed by corrugating the 1 metal at this oifit. The clampmg member 7 is formed'of sheet metal having'a rolled or turned outer edge 8 adapted to turn like a pivot within the chanits inner edge rolled as at 9 to cooperate with the rolled edge-5 to stretch and clam the wire screen or. other cloth between t em. This clamping member is also corrugated as at 10, thus providing an inwardly extending rib opposite the rib 6. I so construct and arrange t in relation to the main frame member and nel 4 ofthe main frame member and having I e two members relatively to each other that the clamping member by pressing it down I place; This resilient or spring action of the members is rendered possible by their eculiar construction, involving as it does t e rolled edges, this being particularly true of the clamping member and being true also of the main frame member when the latter is made of sheet metal, as in theform illustrated. Further than this, the longitudinal corrugation in the clamping member lends itself to this spring or resilient action of this member when it is forced under considerable ressure into" connection with the main ame member; and the same is true of'the corrugated main frame member when this is formed of sh'eetmetal. The spring action is alforded bo'thhy the rolled or turned edge 7 at the pivot point of the clamping member, and also by its rolled inner edge. Further, I so arran e and construct the parts that when the c ampin member is pressed to its 1 seat in the main ame member, the rolled ed e of the clamping member will pass with its h point or crest 11 slightly be ow what may e termed the high-point or crest of the rolled edge of the main frame member, so that thes ring action of the parts will tend tohold t e members togethera It will be seen thatthe screen -cloth-er other fabric extends between the rolled ed es, thence be- 1. In combination in a frame for holding a I fabric, a main frame member formed of sheet metal-shaving a channeled, outer por tion and arrolled inner portion; a clamping member having a rolled outer portionin;

pivotal connection withthe channeled ortion of the main member and having. a to ed inner portion co-acting with the ro inner Portion ofthe rnain f ame memb the Said i members havin lateral resilience and the clamping meml ier being held solely by springing the same into connection With the main frame member, substantially as described.

2. ln combination'in a frame for holding a fabric, a main frame member formed of sheet metal having a channeled outer portion and a rolled inner portion, a clamping member having a rolled outer portion in pivotal connectlon with the outer portion of the main frame member and havin a rolled inner portion coaeting with the rolled inner portion of the main frame member and lying sooner with its crest slightly below that of the rolled inner portion of the main frame member, the said members having lateral resilience and the clamping member being held solely by springing the same into connection with the main frame member, substantially as described.

In testimony whereof ll affix my signature in presence of tWo Witnesses.

CHARLES C. ARMSTRONG.
