Abstract

188,182. Coventry Gauge & Tool Co., Ltd., Harley, H. H., Barker, H., and Hewitt, A. Oct. 21, 1921. Linear-dimension gauges;; surface and outline gauges.-A ring thread gauge comprises a body 2 having a diametral hole in which are inserted two gauge members 4, the adjoining ends of which are semicircularly recessed and threaded to provide the complete ring thread gauge. The members 4 are locked in position by screws 8, and the sides of the body are dished at 11 and bored at 10 in order that the gauge may be used close up to a shoulder. For holes exceeding # in. diameter the body is made in two parts 2, 14, Fig. 4, the members 4 being placed in a diametral slot as before and holes being drilled at each end for the screws 8. The members 4 have bosses 16 so that the gauge may be used up against a shoulder. In a modification, Fig. 6, the members 4 are arranged without the body 2 as before and the whole enclosed within a cage 19 closed on its open side by a plate 21 locked by screws 22. The sides of the cage are dished and recessed. In a further modification, Fig. 8, the members 4 are formed with flanges 27, sufficiently clearance being left to allow the members 4 to be positioned without a diametral slot 25 of the disc 2. In each case when wear of the gauge takes place, the abutting surfaces of the members 4 are ground up and the gauge members relapped or retapped. More than two abutting members 4 may be used and the invention also applies to plain ring gauges.
