Title: Improvements in harvester threshers
IPC: A01D75/00
Filed: 1930-12-29
Abstract: 366,227. Harvesting-machines. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd., 259, City Road, London.-(International Harvester Co. ; 606, South Michigan Avenue, Chicago, U.S.A.) Dec. 29, 1930, No. 39062. [Classes 6 (iii) and 58.] A combined harvesting and thrashing machine of the type in which the harvesting part extends laterally from the thrashing part and may be swung in an horizontal plane from its extended operative position to a position alongside the thrashing devices for transport has the harvester capable of being tilted in a vertical direction to fold substantially flat against the thrasher. The thrashing frame 1 is mounted on a main axle 2 carried by a stubble wheel 3 and a grain wheel 4. An extension 8 of the axle projects beyond the wheel 4 and carries a casting 9 in which a hollow stub shaft 10 may rock, this shaft having an upstanding arm 13 that has on its forward side close to the shaft 10, a horizontally disposed bifurcated socket and, on its rear side, a bearing 15 for a pivot pin 16 round which the harvester frame may be swung. The harvester frame is connected to the pivot pin 16 through two castings 21, 19, which are joined by an horizontal pivot 20 the forward end of which fits in the bifurcated socket 14 when the harvester is in its operative position. The harvester can thus swing up or down to accommodate itself to irregularities of the ground. The harvester support or axle 23 is held with the harvester in working position by a rear brace bar 25 which, when the harvester is to be swung round the pivot 16 to travelling position, is detached from one socket on the thrashing machine frame and inserted in another. The grainward end of the support is supported by a wheel 28 carried in a frame 27 secured by a pivot to the harvester frame. A pin holds the wheel frame rigid when the harvester is in use but may be withdrawn to allow the wheel to caster when the machine is being transported. The harvesting platform 32 is carried by an angle bar 31 mounted on bars 30 forwardly projecting from and pivoted to castings on the support 23. To counterbalance the weight of the harvester frame when it is adjusted for height of cut a rock shaft 37 on the thrashing machine frame carries an arm 38 to which is connected by a brace 48 and a socket 43 a rearwardly extending arm 44 carrying a heavy weight 45. A stud 41 projecting from the arm 13 enters a slot 39 in the arm 38 and so connects the harvester frame with the weighted arm 44. To swing the harvester frame up vertically when it is in its rearwardly folded position a winding drum 54 on the thrashing machine frame may be operated to wind up a cable 55 that can be attached by a hook 56 to the top wall of the harvester platform causing the harvester frame to swing about the pivots of the bars 30. The driving gear of the reel 59 is disconnected to permit the harvester frame to be folded.

Filed: 1959-11-25
Abstract: 874,159. Boiling-point indicators. TECHNICAL OIL TOOL CORPORATION. Nov. 25, 1959 [Dec. 5, 1958], No. 39990/59. Class 97(3) [Also in Group XXIX] In determining the initial boiling-point of a fluid, e.g. gasoline, it is passed through duct 28 into a vaporizing chamber 10 to form a liquid pool which is heated by a resistance coil 34. When the vapour pressure reaches a pre-determined low pressure, such as five pounds per square inch, diaphragm 60 is moved downwardly so that pressure builds up in a passage 66 which has compressed air inlet 67 and outlet 65. This in turn actuates diaphragm 70 so that pressure builds up in a passage 76 supplied with compressed air at 75, and valve 82 is opened to allow liquid and vapour to pass from chamber 10 through duct 42 to outlet 84. A float operated valve 26 then opens to allow more fluid to enter chamber 10. At equilibrium the temperature of the liquid pool, as determined by thermometer T, is a measure of the initial boiling-point of the fluid. If the incoming fluid is hot it is cooled at 30 to a constant temperature below its initial boiling-point.

Abstract: 1516308 Disc brakes; transmitting mechanisms R H BRAUNE 17 Sept 1975 [17 Sept 1974] 40382/74 Heading F2E [Also in Division B7] A disc brake comprises a pair of brake pads 4, 5 carried on opposite limbs of a yoke 21 which straddles a pair of relatively rotatable discs 17, 18 the pads 4, 5 being applied in use to respective outer sides of the discs 17, 18 with opposing axial thrusts. The embodiment of Fig. 2 has pad 4 fixed to one limb and pad 5, which is spring-returned, carried on guides (8) for transverse movement with respect to the other limb. The pad 5 is closed by a bell-crank 9 actuated by a cable 12 and pivoted on a back plate 14 which may be rigid with yoke 2. The yoke 21 may be stabilized in the normal disengaged position of Fig. 1 by an adjustable spring or springs but when traction is applied on cable 12 the assembly of parts 21, 14 move bodily to the right about a pivot axis 22 to engage pad 4, which allows crank 9 to rotate clockwise to close pad 5, whereafter the mutually opposite thrusts of the pads 4, 5 are balanced by the effect of the reaction forces tending to pivot the assembly about axis 22. The pair of discs 17, 18 of Fig. 2 are the driven discs of an infinitely variable speed differential gear connected to respective ones of a pair of road wheels. Fig. 3 illustrates a symmetrical system to provide selective as well as balanced braking of the differential gear of Fig. 2. The yoke 24 is rigidly fixed to a frame by bolts in holes 25 and two spring returned pads 5a, are controlled by respective bell-cranks 9. Cables 28, 29, 30 are anchored to a beam 27, and when central cable 30 is actuated, a crosshead 26 is lifted to contact abutments 31, 32 on cables 28, 29 to thereby actuate the bell-cranks 9. This simultaneously retards both wheels but for selective braking for steering purposes operation of either cable 28, 29 actuates only one pad 5a. Fig. 4 (not shown) illustrates a conventional hydraulic slave cylinder which can replace bellcrank 9. The Specification also envisages the actuating device to be a cam or lever actuated by a cable or rod.

A safety harness for a vehicle is combined with a warning device for indicating when a user has failed to fasten the harness and comprises a belt having a buckle part at each end to be fastened and an electrical switch which is operated by fastening or unfastening the buckle pacts and which is in circuit with a source of current and the warning device. The buckle comprises a part 10 which is insertable within a part 11 which has lateral slots for spring urged pivoted ears 12 on the part 10. Buckle part 11 has spring loaded terminals 14, 15 electrically connected and connected also to the ignition switch of the vehicle and to a conducting plate 31. The terminals are connected to a plunger which is displaced by fastening the buckle to break contact with a plate on which is a terminal 16 connected to an electric motor 30. When the belt is unfastened the conducting plate is driven by the electric motor and the plate has a radial insulating portion 33 whereby the current to a brush 35a in contact with the plate is interrupted and interrupts the current for the ignition circuit and thereby reduces the power of the engine. By fastening the belt, the circuit of the electric motor is broken the conducting plate 31 is arrested and full engine power is restored. To prevent the conducting plate being arrested with the insulating portion 33 opposite the brush contact 35a and thereby breaking the ignition circuit, the conducting plate has a magnetic bar aligned with the insulating portion and a support for the brush contact has a repellant magnetic bar. Instead of or in addition to the interruption of the ignition circuit, a warning light or buzzer is provided. To disconnect the warning means when a safety harness is unused the seat, with the harness, is fitted with a switch in circuit with the warning means and remains open when the seat is unoccupied and closes when the seat is occupied.
