    Abstract: 977,519. Circlips. GENERAL MOTORS CORPORATION. Sept. 10, 1963 [Oct. 16, 1962] No. 35656/63. Heading F2H. [Also in Division E2] A spring clip 26, Fig. 3, e.g. of stainless steel strip, for engaging in an annular groove 22, Fig. 2, and in a diametral groove 24 on the end of a pin 14, has for engagement with the groove 24 a narrow leg 34 of channel form with side walls 36, an upturned end 38 and a tang 40 directed towards a broad, bowed leg 28 having a tapered hole 30 of general keyhole shape whose sides and end engage the annular groove 22. The hole 30 extends up into an upturned end 33 of the leg 28 so that the end of the pin 14 can be introduced there before the clip 26 is moved across to the position shown, when the clip is held on the pin by the abutment of the tang 40 and the hole end 32, Fig. 3, against the side of the pin and the bottom of the groove 22 respectively. The pin 14 is fixed on a crank arm 10 driven by a windscreen wiper motor and the clip 26 secures on the pin a washer 20 and a bush 18 on which a drive link 12 is joumalled.
