<p>572,199. Clips. MILLS, H. E. Dec. 28, 1942, No. 18409. Convention date, Dec. 24, 1941. [Classes 44 and 65 (ii)] In a clip device particularly for securing together apertured plate-like members such as sheet-metal panels, flanges and the like, and of the kind in which a V-form member is adapted to embrace the plate, &c., one of the limbs having an inwardly embossed or stamped out projection or offset adapted to snap into the aperture, the edge of the aperture and of the offset are disposed so that the offset will not disengage from the aperture under force applied parallel to the plane of the plate, no matter in what direction such force is applied. The other limb of the clip may have a similar off-set or may be otherwise formed to hold a second plate, or flange. As described, the aperture is circular and the off-set comprises a pair of oppositely directed segmental or semi-circular lugs 20, which together fit the aperture. The lugs are off-set from and parallel to the plane of the limb and plate, so that the edges of the aperture and lugs are normal to said plane. Figs. 1, 2 show the lugs 20 formed from limb 12 of the clip which is applied to the apertured flange 18. The other limb is slit to provide marginal tongues the free ends 30 of which are bent at right-angles to overlie a plate 34, and a central tongue 32 which is outwardly inclined so that its free end abuts against the lower face of the plate. The end of limb 12 is outwardly flared at 28 to facilitate application. A simple U-form of clip having parallel limbs each of which has inwardly directed off-sets as described, the clip embracing the marginal portions of superposed flange and plate and engaging registering apertures. An S-form clip is also described for connecting overlapping marginal portions of two plates, the outer limbs having inwardly directed off-sets. Fig. 9 shows a form for connecting nesting flanges of articles 80, 82, limb 84 having an inwardly directed off-set, whilst limb 90 which enters the space between the flanges is outwardly bowed and has an outwardly directed off-set. Fig. 12 shows a pair of clips 100, 102 connected together by a pivot-pin 104 so that the flanged member to which the clips are respectively applied are hingedly connected.</p> |
