Abstract: 711,182. Textile combing machines. T.M.M. (RESEARCH), Ltd. Feb. 19, 1953 [March 12, 1952; Nov. 24. 19521, Nos. 6436/52 and 29662/52. Class 120(1) Driving mechanism for the detaching rollers of a rectilinear combing machine comprises an input shaft, a gear train including an internally toothed annulus freely rotatable on the input shaft and a co-operating planet wheel freely rotatable on a bearing member fixed on but eccentric to the input shaft so that on rotation of the input shaft the planet wheel rolls round the interior of the annulus and imparts a constant drive thereto, and means for imparting a periodic supplementary drive to the planet wheel independently of the motion of the input shaft to modify the speed and/or direction of rotation of the detaching rollers. In the mechanism shown in Fig. 1, rotation of a shaft 10, which is an integral extension of or is coupled to or is operated by and at the same speed as, the main comb cylinder shaft, rotates an eccentric bush 17 causing a planet wheel 16 loosely mounted thereon to roll around the inside of and engage internal teeth 15 of an annulus 11 the motion of which through teeth 12 thereof meshing with a pinion 13 imparts a constant drive to a shaft 14 by which detaching rollers are driven: a shaft 24, running at the same speed as the shaft 10, rotates a cam-plate 22 with the cam-track 21 of which a cam-follower 20 fixed to the wheel 16 co-operates to modify the drive to the shaft 14. In the modification shown in Fig. 3, the shaft 10 rotates an eccentric sheave 25 a strap 26 loosely mounted on which carries a planet wheel, one component spur wheel 27 of which meshes with the teeth 15 to impart the constant drive to the shaft 14, and another component 28 of which meshes with the teeth 29 of an annulus 30 loosely mounted on the shaft 10 and fixed to a crank 31 to which a constant oscillatory motion is applied, by a cam shaft 32 acting through a follower 33, lever 35, and link 36, to modify rotation of the shaft 14. Fig. 5 illustrates another modification in which a shaft 46 rotates .an eccentric sheave 45 to operate a connecting rod 43 which imparts to a crank 37 periodic motion which is transmitted through a coupling member 38 by slots 40, 42 and dogs 39, 41. to the planet wheel 16 the drive of which is thereby modified: the crank 37, rod 43, and eccentric drive 44, 45 may be replaced by the arrangement shown in Fig. 6, which comprises a crank arm 47 loosely mounted on the shaft 10 and carrying a cam-follower 48 cooperating wth a cam 49 the track of which may be so shaped as to arrest, for a "dwell" period, by contrary motion, the drive of the wheel 16.

Abstract: 729,094. Change-speed gear. BORGWARNER CORPORATION. March 10, 1953 [March 13, 1952], No. 6561/53. Class 80 (2). Three forward ratios comprising hydraulic low, all mechanical second and hydromechanical split-torque one-to-one high, and hydraulic reverse are provided by two planet trains 47, 48, the former acting alone for all forward ratios and compounding with the latter for reverse, a final output shaft 11 being permanently fast with a rear planet-carrier 58 and connected front ring 51, and the remaining connections being as specified in the following. Low ratio (2.428) is by engaging a friction clutch 15 to drive from an input 10 through a hydraulic torque-converter 14 of the overrun-reactor type, a sleeve shaft 18, the friction clutch 15 and an additional shaft 17 to a front sun 49. With a band-brake 21 applied to the front planet carrier 52, a simple countershaft reduced drive is transmitted to the output ring 51 through intermeshed planets 53, 54. Second ratio (1.700) is by releasing the clutch 15 and brake 21, and engaging only a front clutch 13 to drive through an innermost intermediate shaft 16 the front planet-carrier 52. With the front sun 49 reacting on a one-way detent 19, drive is transmitted mechanically to the output ring 51 by the intermeshed planets. For the one-to-one split-torque high ratio, the clutch 15 is engaged additionally to 13, whereupon the detent 19 overruns, the mechanically driven planet-carrier 52 transmits 59 per cent of the power and the hydraulically driven sun 49 the remaining 41 per cent. For reverse (2.469), the clutch 15 is engaged and a rear brake 22 applied to a freely mounted rear ring 57. The hydraulic drive to the front sun 49 is then compounded in the two trains and issues at the rear planet carrier 58. The clutches and brakes are hydraulically engaged by pressure supplied by input and output pumps 68, 70, which also lubricate the gear.

Abstract: 136,735. Garllus, B., and Knott, F. W. March 17, 1919. Belt gearing.-Gangs of hooks for belt-fastenings are stamped out of wire and arranged as in Fig. 14 on strips of adhesive paper, with large and small hooks alternating. Two strands of wire passing through straightening rollers 36 are pulled forward a short and a longer distance respectively by two reciprocating electro-magnetic grippers such as 37, and are held by a fixed electro-magnetic gripper 38. The travel of the reciprocating grippers is limited by adjustable stops 42, lost motion being provided in the actuating link 30. The blades of a knife 19 which cut the wires obliquely are adjustably carried on the vertically reciprocating die 5, which grips the two blanks against the former 4 at the moment of cutting. The dies 5, 7, 6, 8 are caused to reciprocate in four directions at right-angles by mechanism actuated by cams on the main shaft 2, and timed so that the two blanks are bent by the dies around a former 4 into a large and a small hook respectively. The hooks are moved off the former 4 and step by step along a guide 44 by a member 46 which is reciprocated laterally and vertically in turns by cams on the main shaft. While the member 46 is lifted the hooks are kept in position by spring controlled tongs. The guide 44 is heated electrically at a suitable point, and the heated hooks imbed themselves in the shellac coatings of two paper strips passing round rolls 57, Fig. 5. They are then cooled by an air-jet. The strips are cut into lengths by the knife 60, Fig. 5. This is reciprocated by the long arm 64 of a lever, of which the short arm is engaged by a pawl 62a once in every revolution of the disk 61<a>, i.e. when the pawl drops into the notch 61<b>. The pawl is eccentrically mounted on the main shaft, as is also the pawl 62, which actuates step-bystep the ratchet wheel 61 integral with the disk 61a.
