Inventor: PACKWOOD JOHN
IPC: B60R1/076
Filed: 1970-05-02
Abstract: 1,256,045. Rear-view mirrors. FORD MOTOR CO. Ltd. 2 May, 1970, No. 21232/70. Heading B7J. An exterior rear view mirror assembly for a motor vehicle in which a mirror (not shown) is mounted on a support arm 14, a tapered projection 13 of non-circular e.g. square crosssection on this support arm fitting into a corresponding socket 12 formed in a base 10 fixable to a motor vehicle body panel 11, the projection being held in the socket by means of a coil spring 21 and a spring clip 22 which act on a spring reaction arm 15 loosely pivoted at 16 to the support arm 14. Any force applied to deflect the support arm 14 must initially overcome the action of springs 21 and 22 before deflection of the arm occurs, but as soon as any small deflection of the arm takes place, the projection 13 rides out of the socket 12, and the arms 25 of the spring clip move over a cam form 26 on the spring reaction arm 15.so that the spring clip no longer biases deflection of the support arm 14 to its operative position and only the restoring force of the coil spring 21 must be overcome. The spring clip may be reset by the action of the compression spring since the lower side of the cam form 26 is inclined at a small angle to the spring reaction arm. Alternatively, the projection 13 may be formed on the base 10 and the socket 12 formed in the mirror support arm 14.

Filed: 1954-07-23
Abstract: 786,958. Covering buckles, buttons, and earrings. BERNE, M. S. June 29, 1955 [July 23, 1954], No. 21625/54. Class 43 Articles of personal adornment such as buckles, buttons, and earrings are made by attaching adhesively to a comparatively stiff blank, having the shape of the article, a flexible securing-sheet having the same general shape, but of larger dimensions and having a tacky surface on both sides thereof, one tacky surface being adapted to adhere to the article and the other to receive a decorative covering. The blank may be in the form of a hollow pressing with marginal flanges between which a backing-plate may be fitted snugly against the marginal edges of a tacky surfaced securing sheet and a covering-sheet which may consist of fabric or plastic. The securing sheet may be formed of woven cotton or linen with a tacky coating, e.g. of uncured rubber latex of known composition, on both sides, these coatings being protected initially by sheets of paper that have been treated, for example with wax or size, so that they can be stripped readily from the tacky surfaces. In the example a buckle is formed from two hollow pressed sheet-metal parts 18 and 19, Figs. 5 and 7, which are interengaged, as shown in Fig. 9, after the application of covering-material 32 upon the larger part 18. Fig. 1 illustrates the relative dimensions of an adhesive securing-sheet 10 and the larger buckle part 18, the sheet being provided with a central slot 15 which has a pair of longitudinally extending slits or cuts 17 at each end and cuts 16 extending obliquely from its opposite sides to form flaps which can be folded upon the part 18. One tacky surface of the securing sheet 10 is pressed upon and secured to a piece of the selected covering-material and the latter is trimmed to the shape and size of the sheet 10 and also cut along the lines 16. and 17. The protective paper layer is next removed from the other tacky surface of the sheet 10, and the sheet is placed flat upon a table with the covering material lowermost, after which the buckle part 18 is placed with its smooth surface on the tacky surface so that the slits 16 extend obliquely from the corners of the apertures 22 in the said part. The flaps formed between the pairs of slits in the covering material are then folded around the inner flanges 24 of the buckle part 18, and the marginal portion 11 is folded around the flange 23, the various tacky surfaces being pressed down with the fingers. The smaller buckle part 19 is next pushed into position as shown in Fig. 9, with its flanges 28 and 29 fitting within the flanges of the larger part 18. Finally the covered cross-bar portions 21 and 25 are encircled by the loop 31 of a tang or prong 30, and the loop is contracted to form a rotatable eye. In making a covered button the blank employed is provided with a shank which can be passed through an aperture in a backing plate. In the case of an earring the blank is provided with a fastening which passes through an aperture in a backing member.

Filed: 1923-08-27
Abstract: 218,150. Smith, T. M., and Kent, A. H. V. Aug. 27, 1923. Rope grips.-Jockey rope grips are constructed with cam-operated means for embracing the rope closely without gripping it, leaving the entire hauling force to be obtained by the usual kinking action of the swing- ing jaws on the rope. As illustrated', a corve-engaging rotary stem 2 carries the head 1 on which is formed a fixed jaw 6. A movable jaw 15 is formed on the end of a squared bolt that slides in the fixed jaw and is locked by nuts 18, 19 abutting against the outer surface of the operating lever 10. Rotation of the lever 10 in one direction causes cams 10<a> to co-operate with the outer surface of the head and move the jaw 15 inwards against the action of the spring 22 to embrace the rope closely so as to prevent it leaving the grip on reaching inclines. The weight 24 assists in maintaining the. lever in this acting position. The rotation of the lever can be reversed either by hand or mechanically to enable the spring to separate the jaws.
