Abstract

367,529. Stand heads. HUNTER, C. E., 33, Marryat Road, Wimbledon, London. Jan. 24,1931, No. 2435. [Class 52 (v).] A stand for holding test-tubes, flasks, &c. and having a horizontal upper limb 2 vertically adjustable in a support 3 rising from one side of a foot 4, has a clip for holding the test-tube &c. comprising a pair of lever jaws 6, which may be lined with felt &c., pivoted to limb 2 and closed by a conical member 8 engaging between the inner arms of the jaws and movable along member 2 by means of a nut 9. The member 8 may be separate from the nut and a spring may be provided urging it to the release position when the nut is retracted, or it may be integral with the nut. In the latter case the member 8 may have serrations 8a, Fig. 4, co-operating with yielding projections 7a on the jaws to hold it against accidental rotation.
