Abstract: 421,758. Hinges. CHESTON, A. S., SLEIGH, H. L., Widney Works, Bagot Street, Birmingham, and BOOTH, J. H., Idris, Lichfield Road, Four Oaks, Sutton Coldfield. Nov. 18, 1933, No. 32178. [Class 65 (ii)] [See also Group XXXI] A hinge for sheetmetal structures, such as motorvehicle bonnets, comprises a hinge pin, a rigid cover plate or part of non-circular channel section spaced from the hinge pin, and two hinge parts, associated with the bonnet sections, at least one of these parts being movable relatively to the cover and each having arcuate portions engaging the hinge pin. The cover is supported by these arcuate portions along lines spaced round their exterior, and is maintained in abutting engagement with one or both hinge parts ; it may have a lateral ring at one or each edge, overlapping the inner face of the adjacent hinged member. The hinge parts may have loops to engage the hinge pin, carried by substantially radial portions which form stops limiting the opening of the hinge. A gutter may be fixed beneath the hinge parts. In the form shown each sheet metal bonnet member 10, 11 has its edge doubled under and bent down at 13 and formed with arcuate extensions 14 with radial end parts 15 having loops 16 engaging a hinge pin 17; the parts 14 on the two hinge parts fit between one another. The hinge pin is held in sockets on the bonnet supports, e.g. radiator and dashboard. A cover plate 19 rests on the hinge loops 16 and has wings 24 which are overlapped by the doubled edges of the members 10, 11, the cover plate being thus kept pressed down upon the hinge ; the cover is fixed at its ends to the bonnet supports by screws through its wings, and its engagement with the hinge loops reinforces it laterally. An arcuate gutter 18, fixed at its ends to the bonnet supports, fits against the underside of the hinge parts 14 and carries stop pins 54 for engagement with the parts 15, the parts 14 being slotted to pass the stop pins. Instead of being integral with the members 10, 11, the hinge portions 14, 15, 16 may constitute separate hinge members secured at intervals along the edges of the members 10, 11, for example by welding or riveting. The stop pins may be replaced by inter-engaging tongues on the hinge loops acting in the manner of a dog clutch. The hinge loops may be spaced along the hinge pin by distance tubes, which may be secured to the underside of the cover plate 19. In a modification, the cover 19 is formed integral with one bonnet member 10, the free wing of the cover being fixed to one set of hinge loops ; alternatively this set of hinge loops may be replaced by a set of tongues on the cover projecting beneath the hinge pin, the cover plate having no wing in this form. In these forms the cover may be attached to the bonnet member, instead of being formed integral therewith, by welding or riveting, or by a bent-over edge of the cover hooking into a similar edge of the bonnet member. In a further modification, one set of hinge loops may be formed by extending one edge 24 of the cover to embrace the under side of the hinge pin and extend under the other edge, both edges being then fixed to one member 10.
