Title: Improvements in or relating to tractors
IPC: E02F9/22
Filed: 1955-02-09
Abstract: 764,798. Tractor driving gear. INTERNATIONAL HARVESTER CO. Feb. 9, 1955 [March 17, 1954], No. 3842/55. Class 79(2). [Also in Group XXIX] In a tractor the primary drive shaft of a change speed gear may be driven from either end ; at the front end normal drive may be taken from the engine through a clutch while at the rear end drive may be taken from the engine by way of an auxiliary power transmission giving a reduction in transmission ratio which is additive to the ratios obtainable with the change speed gear. The auxiliary power transmission may be hydraulic or mechanical. The drawings show a tractor with an engine 11 and traction wheels 13 and 14 with driving axles 15, 16 mounted in a final drive housing 21. The crank shaft 23 of the engine is connected to a primary drive shaft 24 of a change speed gear box 25 through a main clutch 26. The gear box 25 has gear clusters 35 and 36 on the primary drive shaft 24, an idler gear 38 for reversing and a driven shaft 29 connected with the traction wheels 13, 14 by means of the bevel gear 45, 46 and a differential gear 47 driving coaxial shafts 48, 49 each of which drive a gear on a traction wheel axle shaft. A shaft 56 of a power take-off unit 54 is coupled at 57 to the primary drive shaft 24 of the gear box 25 and drives power take-off shafts 61 and 65. For the purposes of the invention the take-off shaft 65 is disengageably coupled at 67 to a shaft 69 to which an auxiliary drive may be applied to drive the primary drive shaft 24 of gear box 25 independently of the main clutch 26. The auxiliary drive may comprise an hydraulic pump 74 driven by the engine 11. A control valve 78 with a plunger 81 in the position shown connects conduits 76 and 83 to merely circulate fluid through a reservoir 84. When the plunger is moved to the right conduits 76 and 88 are connected to drive an hydraulic motor 89 which is adapted to drive the shaft 69, and hence shaft 24 of gear box 25. By making the motor 89 of large capacity as compared with the pump 74 and/or by selection of the gear ratios between the motor 89 and shaft 69 and/or the engine 11 and pump 74, a low ratio drive to the gear box is obtained to which the gear ratios of the gear box are additive. An alternative control valve 79a for the hydraulic pump 74 is shown in Fig. 2. Conduits 88a and 91a connect with the motor 89 and a check valve 119 limits the pressure between the conduits. The valve has positions for forward, neutral and reverse drives. In the neutral position shown the lands 108, 109 of the valve piston 107 are by-passed by channels 114 and 115 in the valve casing. For forward drive the reservoir 84 communicates with the valve chamber 117 through a passage 112 in the valve piston 107.

Patent GB-582092-A (GB)
Title: Manufacture of new derivatives of sulphonated amines
Filed: 1943-03-22
Abstract: Derivatives of sulphonated amines for use, either alone or with such substances as inorganic salts, as textile assistants, e.g. as wetting, dispersing, washing, softening, levelling or foaming agents are prepared by treating a naphthylamine disulphonic acid or a salt thereof at a raised temperature and/or in presence of an acid-binding agent with an aralkyl chloride other than a chlormethyl-cymene having at least 8 carbon atoms of which the aliphatically bound chlorine atom is in a single chlormethyl group bound to the aryl nucleus. Naphthylamine disulphonic acids specified are the 2.6.8, 1.2.4, 2.5.7 and 1.6.8 acids.  Especially suitable aralkyl chlorides are monochlormethyl derivatives of aromatic or partially hydrogenated aromatic compounds such as toluene, xylene, cumene, naphthalene, tetrahydronaphthalene, cyclohexylbenzene (obtainable by reaction at 60-70 DEG  C. of the addition compound of benzene and cyclohexene with formaldehyde, hydrochloric acid and hydrogen chloride), anthracene, octahydroanthracene and octahydrophenanthrene.  These may be prepared by passing hydrogen chloride into a mixture of the hydrocarbon, formaldehyde, hydrochloric acid and, if desired, zinc chloride at about 60-70 DEG  C.  Reaction may be effected by addition of the aralkyl chloride to the naphthylamine disulphonic acid in aqueous solution at 60-70 DEG  C. maintained alkaline by addition of sodium carbonate.  In examples, ar-chlormethyl-tetrahydronaphthalene or chlormethyl-naphthalene is added to sodium 2.6.8-naphthylamine disulphonate at 70-75 DEG  C., sodium carbonate being added to maintain alkaline.  The Specification as open to inspection under Sect. 91 comprises the use of any aralkylating agent of at least 8 carbon atoms. Where the product contains a secondary amino group, this may be substituted by treatment with an alkylating agent, e.g. ethylene oxide, glycide and epichlorhydrin, or an acylating agent, e.g. acetic anhydride and butyric, caproic, lauric or stearic acid chloride.  With excess of a 1.2-alkylene oxide, polyglycol ether residues can be introduced.  This subject-matter does not appear in the Specification as accepted.

Abstract: 938,101. Linkwork. TELEHOIST Ltd. Feb. 11, 1960 [Feb. 11, 1959], No. 4730/59. Class 80 (3). [Also in Group XXIX] In a manual control device, particularly for the pump drive and valve of a tipping ram in a vehicle, a collapsible spring-loaded handle 2 on a column 1 is (1) pivotally raised to the operative portion shown, (2) turned about the column axis to start the pump, and (3) moved pivotally up or down to actuate a link 28 controlling the ram valve, " floating link " means 7 rendering the up and down movement ineffective unless or until the turning movement has been made and held. As shown, the column 1 comprises a fixed outer tube 3 and a rotatable inner tube 4 actuating the pump-starting linkwork 31. The tube 4 has a lug 6 on which is pivoted a " floating link " 7 one end of which has a pivot 12 carrying the handle 2 while the other end passes through an opening in the tube 4 to engage an L-shaped slot 9 in the tube 3. The handle 2 is pivoted at 15 to valveactuating linkwork 16, 17, 27, 28 which is biased to a central position by a spring 23 engaging pins 24, 25 on the link 17. Normally, the end of the floating link 7 is free to move up and down in the axial portion of the slot 9 so that handle 2 can move up and down about pivot 15 without moving the link 16 but cannot rotate about the column axis. If, however, the handle is raised to the horizontal position shown the link 7 can enter the circumferential portion of the slot 9 and the handle can be rotated about the column axis to rotate tube 4 and start the pump. The engagement of link 7 with the upper and lower edges of the slot 9 prevents it floating so that the handle 2 can be moved about pivot 12 to actuate link 16. Friction between the link 7 and the edges of slot 9 holds the pump-control tube 4 in its adjusted position.
Patent GB-646401-A (GB)
Title: An electromagnetically-operated step-by-step selector switch
IPC: H01H67/06
Filed: 1948-02-18
Abstract: 646,401. Electromagnetic switches. GUARDIAN ELECTRIC MANUFACTURING CO. Feb. 18, 1948, No. 4753. Convention date, Dec. 22, 1938. [Class 38(v)] In a selector switch successive impulses at a rairly rapid rate to an electromagnet 40 cause the step-by-step rotation of a primary ratchet wheel 18 with its attached contact arm followed by the step-by-step rotation of a secondary ratchet wheel 26 with its attached contact arm. If the rate is not fast enough, the primary ratchet wheel is returned to the starting position 'before the next impulse arrives. The ratchet wheel 18 is loosely mounted on a shaft 11 to which the ratchet wheel 26 is fixed. Springs tend to bring both wheels to a starting position in which portions of the wheels bear against a stop 34, but such movement may be prevented by check pawls 56, 57 which are pivoted at 55 and tend, under spring bias, to engage ratchet wheels 18, 26 respectively. The toothed portion 18a of the wheel 18 is of greater radius than the toothed portion of the wheel 26. The pawl that operates both ratchet wheels consists of a U-shaped member or bail 50, the centre portion of the U engaging the wheels and the ends being pivoted to a member 48 fixed to the armature 43. Thus when the armature is reciprocated the bail first engages and drives the wheel 18 till a tooth 18b is reached, after which the wheel 18 stays still and further reciprocations drive the wheel 26. Prior to this, however, the engagement of the pawl 50 with the tooth 18b causes the pawl to engage and lift the cam-shaped end of the check pawls 57 causing the ratchet wheel 26 to return to its starting position. Should the impulses to the electromagnet not follow at sufficiently close intervals, the check pawl 56 for the primary ratchet wheel 18 is lifted by a spring-biassed toothed segment 59 engaging a part 56d. In normal operation, however, the segment 59 is moved upwards away from the part 56d by the member 48 on the armature engaging the tail 76 of the lever 74 pivoted at 72 whenever the armature is attracted. At each release of the armature, the segment 59 tends to return but this return movement is delaped by an escapement mechanism 68, 70.
