Title: Improvements in or relating to hay cocking machines
IPC: A01D85/00
Filed: 1957-02-27
Abstract: 795,508. Hay-cocking machines. GIBSON, J. Feb. 27, 1957, No. 6573/57. Class 6(3). In a hay-cocking machine, the hay-mould 65 is slidably mounted on the machine-frame with its apex uppermost, the hay being forced into the mould at its bottom, open, end. The angle-iron machine-frame 1 is supported on wheels 3 and towed by a bifurcated hitch 4 which is pivoted at 5 to the frame but is normally looked rigidly to it by the engagement of a collar 8 on a pivoted lever 9 with a bracket 10 integral with the frame ; forward movement of the lever disengages the collar and bracket and allows the frame to tilt backwardly about the wheel-axle 2 to discharge the cock. The mould comprises a split-rim 65 to which are attached loops 68, the loops being folded down flat, in the plane of the rim, when the mould is empty, and being interthreaded with a rope 74 which is also passed through rings 73 on a cap member 70, the ends of the rope being wound on to a spring-loaded spool 75, so that the rope is gradually unwound as the cock expands. The feeding mechanism comprises serrated discs 48 mounted on a driven shaft 49 floatingly supported by arms 50 and urged forwardly by springs 55. The hay is then fed upwardly by two sets of star-shaped feeding plates 38, 39 mounted on shafts 36, 37 normally rotating in opposite directions. The plates are interspaced between toothed drums 33, 34 mounted on shafts 31, 32 normally driven in opposite directions. The drive to the shafts 32, 37 is by chains 40 and sprockets 41, 42, 43 from a shaft 18 which is driven unidirectionally, through bevel gears 15, 16 and a clutch 19, 19a, from the shaft 14 connected to the tractor power take-off, the gear 16 being free on the shaft and being clutched thereto by the elements 19, 19a. A gear 17 free on the shaft can be clutched to a sleeve 28 by the movement of a double-sided dog-clutch element 25 ; reverse movement of the element clutches the sleeve 28 to a boss 27 fixed to the shaft 18 whereby the sleeve is rotated in the opposite direction. The sleeve carries a sprocket 45 which drives the shafts 31 and 36. The shaft 49 is driven by chains 61 from the shaft 32. The mould-rim 65 is secured to an arcuate member 77 which is continuously reciprocated on rails 79 by cranks 86 and connecting rods 85 on the shaft 18. Parallel flat wooden laths 99, 100, form a platform on which the hay is spread and compacted while the mould oscillates. When the mould is full, the rim 65 is detached from the member 77, the lever 9 is pulled to allow the whole machine to tilt about the land-wheel axis 2, and the clutch-element 25 being then moved to reverse the direction of rotation of the drum 34, whereby both drums 33, 34 rotate in the same direction to propel the mould over the laths 100 on to the ground. The split rim is then released, leaving the hay-cock on the ground and the collapsed mould resecured to the arcuate member 77.

Abstract: 136,415. Pool, H. L. March 17, 1919. Keyboard stringed instruments. - Strings are plucked by plectra mounted on disks which may be caused to rotate by pressing the corresponding key of a keyboard. In the instrument shown, the disk c is mounted on a lever d pivoted at d' and connected by an adjustable rod d<9> to a key d<4>, pivoted at d<5>. Depression of the key brings the disk c into frictional engagement with a cylinder b which is kept in rotation by a pedal or by power: this causes rotation of the disk c and periodic plucking of the string a<1>. A spring d<10> restores the key and disk to their normal positions when the pressure on the key is removed. The levers d are mounted on a bar d<3> which may be moved transversely to the strings by a wedge. Fig. 5 shows a section of one of the disks. Each plectrum c<3>, of which the disk may carry three, is adjustabl fixed in a socket c<4> mounted to rotate in a bearing c<5> against the action of a spring, shown in section at c'; the motion of the socket is limited by an adjustable stop c<8>. The disk may have a rubber or other tyre c<1>, and the cylinder b may also be covered with rubber. The strings are preferably of steel and are arranged in monochord or trichord over a sound-box a.

Abstract: 1305602 Copying; controlling machine slides truing grinding wheels SOC A2 INDUSTRIE MECCANICHE PADOVANE 11 Feb 1970 [11 Feb 1969] 6664/70 Headings B3B B3D andB3T Apparatus for controlling the movement of a cutting tool in a machine tool such as a lathe or grinding wheel truing machine comprises a tool 9 secured to a first slide 8 which is movable on a second slide 6 which in turn is displaceable on a movable support 3 on the machine, the first slide being movable transversely to the second slide and the second slide being movable relative to the support and in the same direction of movement thereas. The first slide is provided with oblique guides 12, 13 which are respectively engaged by roller followers 15, 14, carried by the second slide and are under control of a fluid actuated piston and cylinder 17, 18, the second slide being movable on the support 3, by a further fluid piston and cylinder 19, 20. A template 4 carried by the support 3 co-operates with a template follower 10 on the first slide so that in operation the tool engages the grinding wheel or workpiece 1 when the follower 10 engages the template 4 and fluid under pressure admitted to the cylinder 20 moves the slide 6 parallel to the axis of the grinding wheel and the fluid pressure in the cylinder 18 is controlled and biased in the direction of movement of the slide 6 so as to tend to urge the slide 8 by way of roller 14 and guide 13 in a transverse direction and which movement is restrained by abutment between the feeler and the template. For all movement parallel to the axis of the wheel 1 or workpiece no relative displacement occurs between the piston 17 and slide 6. However when the feeler 10 reaches a shoulder on the template 4 the piston 17 under its biasing pressure is displaced and causes immediate transverse displacement of the first slide relative to the second slide and proportional movement of the second slide to the support. In the embodiment shown in Fig. 2 which is concerned with copy turning a fluid actuated feeler 42 is provided which controls the movement of piston 44 which effects actuation of the oblique guides and followers 13, 14. The apparatus is effective in either direction of movement parallel to the axis of the workpiece. In a further embodiment the feeler may be controlled to emit electrical signals which are arranged to actuate a drive motor and screw which effects transverse movement of the slide. Alternatively the drive motor may be under digital control.

Title: Improvements in or relating to thermionic valve amplifiers
IPC: H03F3/52
Filed: 1936-03-06
Abstract: 471,549. Valve amplifying circuits. KOLSTER-BRANDES, Ltd., and ROBIN, H. K. March 6, 1936, No. 6822. [Class 40 (v)] The output load impedance r is included in common with the anode - cathode and cathode-grid circuits so as to give a feedback voltage to the grid equal to that across the output impedance and in phase opposition to the input control voltage. By this means the valve is enabled to work directly into a low output impedance of approximately 100 ohms such as a transmission line, and although the voltage V2 may only be half the voltage V1, yet with a 40 to 1 step up input transformer S a power gain of 20 decibels can be obtained. The system greatly reduces crossmodulation when the valve is used for amplifying a number of carriers received on a common aerial before distribution to the respective receiving sets, and is also suitable for use as a television or as a high quality amplifier. A system using two such amplifiers in push-pull is disclosed and also a Lecher wire system with pea-nut valves arranged every quarter wave length in a concentric system, the low impedance input to the Lecher wires being directly connected to the impedance r and the virtual high-impedance output of the Lecher wire allowing of direct coupling to the next valve without the insertion of the step-up transformer S.

Title: Engine mountings
IPC: B64D27/04
Filed: 1936-03-13
Abstract: 468,578. Mounting aircraft and vehicle engines. ELLOR, J. E. March 13, 1936, No. 7136. [Class 4] An aircraft engine is supported at each side by a framework through resilient material stressed in shear in order to permit the engine to rock about a longitudinal axis relatively to the framework against the resistance of the resilient material. The framework shown in Fig. 1 is composed of steel C ... C' connected to the fuselage &c. by ball-and-socket joints D, D<1> and to bosses A<1> on the engine A by means of brackets B and plates E formed at the junctions of the tubes C<2>, C<3>, C<4> and C, C<1>, C<4> respectively. The plates are shaped similarly to the outer surfaces F of the brackets B, which, as shown in Fig. 3, are concave. Alternatively, the surfaces may each be formed of two plane portions set at an angle to one another or of a single flat portion inclined to the vertical. Strips H of indiarubber are placed between the surfaces F and plates E, and between the plates and similarly-shaped washers G which are then bolted together. Each bolt J has a squared portion J<3>, Fig. 6, in contact with the sides but spaced from the top and bottom of a hole through the plate E and rubber strips H, thus permitting limited rocking of the engine about a longitudinal axis. To limit the compression of the rubber strips, a shoulder K on each bolt J is adapted to abut the surface F when the nut J<1> reacts against a boss J<2> on the bracket B. To allow for engine expansion under heat, the connecting bolts B<1> pass through longitudinal slots in the brackets B. The engine may also be supported centrally by one or more supports under the engine resting on resilient material. According to the Provisional Specification, the invention may be applied to the mounting of road or other vehicle engines.
