Title: Gear wheel testing instrument
IPC: G01B5/20
Filed: 1953-10-23
Abstract: 736,574. Testing gear teeth. ERNST, D. Oct. 23, 1953, No. 29389/53. Class 106 (2). An instrument for testing the helical and involute flank profiles of a gear-wheel tooth comprises a shaft 3 for both the gear-wheel 4 to be tested as well as a generating cylinder 5, a first sliding member 6 in driving engagement with the cylinder 5, a second sliding member 11 movable parallel to the member 6, and a lever 7 rotatable about a pivot 8 fixed in relation to the shaft 3. The sliding member 11 is pivoted to the lever 7 at 10 to be moved by it, the sliding member 6 being pivoted to the lever 7 at 9 to be moved by it, and an angularly adjustable third sliding member 14 is set to slide at the helix angle B degrees of the tooth to be tested and coupled to the sliding member 11. The grooved member 15 for the sliding member 14 is displaceable parallel to the shaft 3 by a lead-screw 27 and/or at a tangent to the cylinder 5 by a lead-screw 26, and a feeler 22 pivotally connected to the slide 14 about an axis parallel to the shaft 3 contacts the tooth to be tested on a line tangential to the base circle of the gear-wheel 4. The distance between the sliding member 11 and the axis of the shaft 3 is varied by a hand wheel 25 until the feeler 22 is on the base circle. The apparatus is so designed that the axes of the pivots 8, 9 and 10 are displaced in the same direction by equal distances a from the shaft 3, the tangent to the generating cylinder 5 and the tangent to the base circle respectively as shown, and such that the ratio of the lengths of the lever 7 are always in the ratio of the radius of the generating cylinder 5 and the base circle respectively. Operation. To test the accuracy of a helical profile, the feeler 22 is brought into contact with a tooth flank 4, preferably at one end thereof, and adjustments are made to bring a point at the rear end of the feeler 2 into coincidence with a zero line on a chart on a drum 23. The lead-screw 27 is then operated to cause the feeler 22 to move vertically. This vertical displacement causes relative movement between the members 14 and 15 to turn the lever 7 about the pivot 8 and impart rotation to the generating cylinder 5 and hence to the gear-wheel 4. If the helical profile has been correctly machined, the recording point of the feeler 22 will draw a straight line on the chart. To test the involute profile of a tooth flank, the lead-screw 27 is held stationary and the leadscrew 26 turned so that the slide 19 moves along the bed 1. This movement causes the disc 15 and member 14 to rock the lever 7 through the arm 13 and hence turn the gear-wheel 4. The arrangement is such that if the gear tooth under test has no departure from the true involute profile the recording point on the feeler 22 will not depart from a zero line on the drum 23.

Title: Improvements in agricultural machines
IPC: A01D34/24
Filed: 1946-10-03
Abstract: 617,481. Reaping machines ; root crop harvesters. BAMFORD, C. J.. and BAMFORD. H. V. Oct. 3, 1946, No. 29457. [Class 6 (iii)] Agricultural machines having crop engaging tools which are raised from and lowered to their working positions have a half-revolution clutch comprising a continuously driven rotating element which imparts successive half-revolutions in the same direction to a normally stationary element so that a link connected to the latter is positively reciprocated thereby, the continuously driven element being actuated from the road wheel axle or any suitable source of power, the said clutch operating a link and lever system connected to the cutter bar or the reels of a root crop harvester, the arrangement of said link and lever system being such that the working tool is retained in its raised or lowered position wholly or mainly by the link and lever system and independently or partly independently of the clutch. Referring to Fig. 1, the clutch 17 is mounted on a countershaft 13 in driving connection with the road wheel axle 12, and comprises a continuously driven part and a normally stationary part. Referring to Fig. 3, the driven part 18 comprises a drum 21 recessed on one side which recess has teeth 22 with which an arm 32 of a lever 27 engages whereby the part 19 is driven by the part 18. The part 19 comprises a wheel with its periphery formed as two cam surfaces 25 with shoulders 26. Two interconnected double armed levers 27, 28 are pivoted to this disc each having a latch member 35, 36. The operation of the clutch is such that when a roller 40 on an operating lever 39 is disengaged from one latch member, a spring 34 pulls the latch away from the shoulder ; this moves the arm 32 into engagement with the teeth 22 so that the part 19 rotates and the roller rides down over the cam surface until it engages the other latch and pushes it back into line with the shoulder which disengages the arm 32 from the teeth 22 and stops the part 19. An actuating lever 42 pivoted to the part 19 is thereby moved, and through a linkage system 43, 44 raises or lowers the working tool. The links 43, 44 are pivoted together on a pin 45 passing through a slot 9 in the lever 42, said slot being provided in order that the lifting and lowering may be manually effected by means of a lever 59 and link 60. In a modification, Fig 5 (not shown). the lever 43 may be replaced by a channelled rail, the lever 43 having a roller at its base to ride in said channel. In a further modification as applied to a root crop harvester, Figs 6-8 (not shown), the tools are retained in either the raised or lowered position independently of the clutch as two link systems are provided each of which passes on through a dead centre position. Specification 520,436 is referred to.
