Abstract

949,461. Cutting-tools; turning. G. NEIDL. Dec. 14, 1959 [Dec. 29, 1958; Aug. 5, 1959], No. 42369/59. Headings B3B and B3T. [Also in Divisions B2 and F1] A pump impeller comprises a flat plate 1<SP>1</SP>, Fig. 2, mounted obliquely on a shaft 4<SP>1</SP> so as to execute a swashplate motion when the shaft is rotated. Teeth are formed in the periphery of the impeller by mounting the shaft 4<SP>1</SP> in a lathe chuck 5<SP>1</SP> and cutting successive pairs of grooves 9<SP>1</SP> in the arcuate edges 7<SP>1</SP>, 81 by a tool 6<SP>1</SP>. Similarly, pairs of grooves such as 13<SP>1</SP> are cut in the flat end edges by a tool 12<SP>1</SP>. The pump casing is formed with annular grooves engaged by the teeth on the impeller. Two sections 116, 117, Fig. 11, of a four-section pump casing are shown attached to a lathe faceplate 123<SP>1</SP>. The cutting tool 124<SP>1</SP> shown in Fig. 13 is used to cut annular grooves 113 one at a time, the tool being indexed in either direction 126<SP>1</SP> between each cut. Alternatively, the tool 127<SP>1</SP>, Fig. 12, may be used to cut all the grooves 113 simultaneously, but in this case some of the grooves will be incomplete or absent, necessitating a further cutting operation. Specification 949,463 is referred to.
