No. 14635.—7th March, 1902.—FRANK GOUGH, of German Creek, Stafford, New Zealand, Miner. Improved leg-holder for milch cows.

Description of Invention.—Two bars D and E, made of iron, steel, or other like material, one of the said bars E being about 4 in. longer than the other; the longer bar E having one end turned to form a ring G, and the other end turned to form a hook F 4 in. long by 2 in. wide, with a rest on the end turned up, H; the shorter bar D having one end turned to form a ring I, with the end of the material forming the ring I turned down, and the other end fastened to a cross-bar 4 in. in length, J; the said cross-bar being fastened to the longer bar 4 in. from the end thereof, and fitting across the top of the hook of the longer bar, with the end of the cross-bar fitting into the rest H on the top of the said hook; the fastenings to be made so that the shorter bar can be worked backwards and forwards, thereby opening and closing the top of the hook of the longer bar. A piece of rope or other like material is passed through the rings on the two bars, then when the turned-down end of the ring on the shorter bar is put into the ring on the longer bar and the rope is pulled tight the cross-bar is held firmly across the top of the hook of the longer bar.

Claim.—The manner in which the cross-bar is made to open and close over the top of the hook on the longer bar.
