1,066,782. Hose clips. G. L. NIGON, July 9, 1964 [July 15, 1963], No. 28339/64. Heading E2B. A hose clip comprises a strip 20 to encircle the hose, an actuating member 61 and means by which the actuating member is mounted on one end portion of the strip to be rotatable about an axis normal to the surface of the strip, the actuating member being formed with at least one projecting rib adapted to cooperate in use with the projections on the other end portion of the strip to feed the said other end portion lengthwise of the strip over said one end portion to vary the loop size. In the construction shown, the means for mounting the actuating member is a housing constising of a base plate 32 and a retainer 60 and the strip 20 is formed near one of its ends with a cut out hook 22 which engages a slot 37 formed in the base plate to attach the housing to the strip. The retainer is secured to the base plate by bending a pair of lugs underneath the base plate and it is shaped so that the free end portion of the strip which is provided with a plurality of cut out projections 113 can be passed between the base plate and the actuating member 61 a portion of which protrudes through an aperture in the top of the cap. The actuating member in one form is formed with a single projecting rib of spiral form on its under face which is engageable with the projections 113. The actuating member is provided with a screw driver slot to enable it to be rotated and it is also hexagonal shape so that the spanner can be used. The screw driver slot can be linear and closed at both ends in one form or it can be of cruci-form shape. The head of the actuating member can also be provided with the bore through which a sealing wire can be passed. Instead of providing the actuating member with a single spiral rib it can be provided with a plurality of ribs. The projections 113 of the strip can take various forms. |
