Title: Improvements in or relating to means for hitching agricultural implements to tractors
IPC: A01B63/112
Filed: 1959-03-04
Abstract: 862,516. Tractor power-lift mechanisms. CLAUSING, H., [trading as RABEWERK H. CLAUSING.]. March 4, 1959 [March 4, 1958], No. 7601/59. Class 79(1). In an automatic draft control system for attachment to the three-point hitch linkage 2, 3, Fig. 1 of a tractor 1 and in which a spring 11 yields under preset draft forces of a plough 5, with resultant lifting of the plough a damping device 13 is connected to the spring 11 to prevent oscillation. The lower links 2 are attached to one arm 7 of a bell crank 8, the other arm 9 having alternative connections for a compression unit 12 containing the spring 11 and incorporating a hydraulic damper 13 and restriction valve 60. The arm 9 is also coupled to a push rod 18 having a slotted end 19 permitting lost motion and engaging a pin 20 attached to the lift arm 21 of the hydraulic lift system 22 so that the lift arm is automatically raised to lift the lower links 2 through lift rod 23 when the spring 11 yields. Initial compression of the spring 11 is preset by a hand control 16. Numerous examples are described in which a two armed lever such as 7, 9 is attached to the tractor or parts of the hitch linkage and in one example the arm 9 Fig. 5 is coupled through a push rod 33 to a second bell crank 30, 31 to which the upper hitch link 3 is attached so that the plough coupling member 4 undergoes parallel movements to maintain the plough at the same angle of operation. In other examples in which the lower links 2, Fig. 8 are held in a fixed position through the lift linkage 22, 23 the coupling member 4 is connected between the top link 3 and a bell crank 36 on the lower links and carries the spring unit 11. The plough 3 has a second coupling member 38 attached between the bell crank 36 and a link 39 on the member 4 so that the plough 5 lifts against spring 11 with increased draft force. In another example in which the linkages 2, 3 Fig. 13 are free to float and are supported by a wheel 50 through a bell crank 48, 49 which is yieldingly held by the spring unit 11 and causes the linkages 2, 3 to rise with increases of draft load. In another example a hydraulic control unit 58 Fig. 15 incorporating the spring unit 11 is attached to the support 4 and carries the plough 5 on an arm 47 which is rotated by a hydraulic ram (not shown) under the control of a valve which is actuated when the draft forces in the lower link 2 cause the spring 11 to deflect.

Patent GB-598366-A (GB)
Title: Improvements in fluid-pressure braking systems
IPC: B60T8/18
Filed: 1945-03-29
Abstract: 598,366. Brakes. SOC. ANON. A. CITROEN. March 29, 1945, No. 7944. Convention date, June 12, 1942. [Class 103 (i)] Brake cylinder pressure, in a hydraulic system, is varied according to the loading on the axle, variations in which alter the mechanical advantage of a lever, one end of which is acted upon by a piston actuated by the primary master cylinder and the other end of which actuates a piston in a second master cylinder to build up pressure for use in the brake cylinder. As shown in Fig. 2, the lever 7 pivoted at 8, is positioned according to the loading on the wheel or axle, and correspondingly positions the roller-end 2 of the link 1 relatively to the lever 3. The primary master cylinder pressure is admitted at 9, and is transmitted past the valve 10, normally held open by the spring 11, to the cylinder B and to the port 12 leading to the brake cylinder. When the shoes reach the drums, primary master cylinder pressure rises and acts on the piston 13 to close the valve 10, the increased pressure serving to lift the valve 14 from its seat and open communication from the said master cylinder to the cylinder A. The piston A<1> is thus forced out and, through the links 1, 4 and lever 3 builds up pressure in the cylinder B and the brake cylinder, the effective pressure depending on the load-determined leverage ratio. When the primary master cylinder pressure is relieved, the pressure in the cylinder A opens the valve 16 and permits the return of the pressure fluid. The Specification as open to inspection under Sect. 91 describes also a construction in which the master cylinder pressure exerted on a plunger, is balanced by the actual brake cylinder pressure exerted on another plunger which is mechanically connected with the first plunger by a see-saw like beam, the fulcrum comprising a roller which is displaceable according to the loading on the axle. The second plunger compresses a valve which controls the flow of fluid from the master cylinder to the brake cylinder, the arrangement being such that the brake cylinder pressure is reduced in accordance with the position of the said fulcrum. This subjectmatter does not appear in the Specification as accepted.

Abstract: 863,261. Pipe joints. JOHN THOMPSON WATER TUBE BOILERS Ltd. March 13, 1957 [March 13, 1956], No. 8312/57. Divided out of 863,260. Class 99(1). A flexible joint for ducting comprises metal bellows 1, having a restraining member 8 extending axially therethrough and secured relative to the bellows at both ends thereof, the member 8 being capable of flexing readily, relative to the bellows, in one direction only, and a coupling secured externally to each end of the bellows, the coupling permitting the flexing but substantially precluding relative torsional movement of the bellows ends. Member 8 may be as described in Specification 863,260. In one embodiment, Fig. 1, cylindrical covers 11, 12 have flanges 11a, 12a secured to end rings 4, 5 welded to the bellows ends and to lengths of ducting 6, 7.

Title: Improvements in and relating to optical projecting apparatus for advertising
IPC: G09F19/18
Filed: 1921-03-17
Abstract: 181,804. Bendmann, H. March 17, 1921. Moving and changing apparatus.-In opticalprojection apparatus, wording on a slide is displayed letter-by-letter and line-by-line on a screen by means of an obscuring-device comprising two members b, c. The member c moves across the slide d to expose a line and is carried by the member b which moves intermittingly at right angles, approximately, to the member c to expose a fresh line. The slides d are connected together to form a chain which passes over rollers e through which hand, clockwork, or other power is transmitted to the device. On a shaft slides a pinion i which can engage a toothed wheel k mounted at the end of a lever f<1> pivoted at f to the member b. At the other end of the lever f<1> is a swinging nose g which when vertical holds the wheels k, i in engagement and traverses the member c through a pinion h and rack c<1>. The nose g bears with small friction on the member c and is knocked out of the vertical by a projection l on the member c when this reaches one end of its movement. A spring f<2> then tilts the lever f<1> to disengage the wheels k, i and allows the member c to slide back under the action of a spring m, a projection l<1> then coming against the nose g and forcing it back to the vertical position. The wheels k, i are thus re-engaged and the member c commences another traverse. At the end of its backward motion under the action of the spring m, the member c strikes against a catch o and moves it out of engagement with a notched rod p to allow the member b to move under the action of a spring u through the space of one notch, which may have the depth of one or more lines. The catch o is stated to be actuated and timed to secure the step-by-step advance of the member b. When the member b has reached the limit of its movement, it strikes against a rod x and moves a bell-crank w to release the slides d and allow the next slide to move forward into position, bringing with it the members band c. This is effected by a cord s<1> being wound on a pulley s on a roller shaft. A one-way clutch between the pulley s and a casing r winds a spring therein which transmits power through bevels q for the pinion i during the progressive motion of the member under the action of the spring u.
