Abstract: 426,955. Hinges. CHESTON, A. S., and SLEIGH, H. L., Widney Works, Bagot Street, Birmingham, and BOOTH, J. H., Idris, Lichfield Road, Four Oaks, Sutton Coldfield. Oct. 11, 1933, No. 28009. [Class 65 (ii)] [See also Group XXXI] A hinge for connecting the two parts of a motor-vehicle bonnet or for the cover of a dickey seat comprises two interengaging arcuate parts extending along the edges of the respective members below their visible surfaces and covered by a part level with these surfaces to give a substantially flush appearance. In the form shown in Figs. 1 and 2, two bonnet halves 12, 13 have trough-like members 10, 11 respectively fixed to them by interengaging their edges as shown; the parts 10, 11 rest in a trough 15, or a pair of short troughs at the ends, carried by the radiator and dashboard and are held together by a member 14 which closes the trough. The member 14 extends beyond the parts 10, 11 at the ends, and has spacing parts 17, Fig. 2, welded to it and to the trough, these parts resting in a recess in the radiator or other support and being secured by a strip fixed across the top of them ; the bent-under edges of the members 12, 13 are also cut short, but in the form shown these members themselves extend over the securing strip, which engages a flattened end of the member 14. The parts 17 only extend over a part of the arc of the trough 15, and are provided on opposite sides at the two ends, so that when the hinge is detached from its supports both members 12, 13 may be removed by opening them through 90‹ and sliding each off one end. In a modification, the troughs 10, 11 may be integral with the members 12, 13 ; the bent edges 23 of these members may overlap ledges on the member 14 to make the hinge more watertight. Relative movement of the members 12, 13 may be limited by arms 19 fixed to one member and provided with bent ends 20 to engage the ends 201 of similar arms fixed to the other member ; alternatively, a projection on one of the trough parts 10, 11 may engage a slot in the other. In a modified form of the hinge, Fig. 8, the inner trough 10 is part of a tube formed by rolling over the edge of the bonnet member 12. In order that the exposed part of the tube may not be scratched by touching the inside of the trough 11 during movement of the parts, the lower part of the tube may have an arcuate spacing part fixed to it to bear in the trough or the upper part of the tube may be Battened or otherwise set inwards from the circular form. The shaping of the tube in the latter cases renders the vertical depth of the tube less than the width of the trough 11, so that the members 12, 13 can be easily separated when one is turned through 90‹ relatively to the other ; in order to prevent detachment in normal use, the members 12, 13 are slotted at 29 to engage an arcuate strip member fixed on the bonnet support. According to the Provisional Specification, the middle part of the underside of the trough members 10, 11 may be cut away, the adjacent parts of the members 12, 13 being stiffened by angle members fixed to their undersides close to the hinge. The trough 11 may be connected to the member 13 by an L-shaped portion instead of merging directly into it. The edges of the members 12, 13 may extend beyond the edges of the troughs or tube attached thereto and may abut in the closed position, in which case one or both edges may be chamfered and may lie on a circle having its centre on the hinge axis.
