Title: A machine for harvesting bulbous plants, potatoes and other tubers
IPC: A01D17/00
Filed: 1964-05-06
Abstract: 1,058,213. Root-crop harvesters. A. T. HEEMSKERK. May 6, 1964, No. 18906/64. Heading A1F. A root-crop harvester comprises a share 4 for digging the crop and transferring it to a conveyer, the share being united at its rear end with a grid of longitudinal rods 6 and the conveyer consisting of a series of rotary rollers 10 extending transversely and each carrying a row of circumferential resilient studs 11, the studs of adjacent rollers being staggered, and means being provided for vibrating the shovel and grid longitudinally. Behind the conveyer is a vibratory sieve 13 consisting of longitudinal bars, the sieve being supported on swing- ing levers 15 for longitudinal oscillation imparted by eccentrics 20 on a driven transverse shaft 19, the same eccentrics also driving the share and grid through a connecting rod 21. As shown, there are two shares 4 side-by-side, each share being preceded by a scraper-blade 8 of V-shape in plan. The device is mounted on groundwheels 2 and driven by a power take-off 16 which also drives the rollers 10 through a chain-drive (not shown) entraining sprockets on their outer ends.

Title: A Locking Mechanism for the Guards and Covers of the Lap Forming Rollers of Textile Machines.
IPC: D01G31/00
Filed: 1917-12-22
Abstract: 116,851. Hetherington & Sons, J., and Snape, T. H. Dec. 22, 1917. Interconnecting guard with starting-gear.-Relates to locking mechanism for the covers of lapforming rollers of textile machinery such as sliver and ribbon lap machines and Derby doublers. When the hinged cover j is closed, as shown in full lines, a projection j<2> on it enters a box m and depresses a spring rod n. A rod p connected to the lever f or other gear for operating the belt fork d can then pass through an opening in the projection j<2>, and the belt brought on to the fast pulley c'. The cover is then held locked until the rod p is withdrawn by moving the belt on to the loose pulley c. When the cover j is opened, the rod n rises and blocks the rod p, thus preventing the belt from being returned to the fast pulley until the cover is closed.

Abstract: 715,430. Radio receiving systems. PLESSEY, CO., Ltd. July 23, 1953 [July 28, 1952], No. 19017/52. Class 40 (5) In a diversity .reception system, volume compression means, preferably following a logarithmic law, are provided in each signal channel in advance of the signal comparator which controls the diversity switch. In the embodiment described, the channel signal from input A is applied i to a volume compressor comprising resistance 1 and rectifiers 2, 3, the output from which is amplified in triode 4, and tetrode 12, which acts as a limiter, and thence passes to the common output coupling condenser 41. The channel signal from input B is fed to volume compressor 14, 15, 16, triode 17, tetrode 25 and thence to condenser 41. The diversity switch comprises a bistable trigger pair 27, 28 the anodes of which are connected to the screen grids of tetrodes 12, 25 respectively, so that only one of these is operative depending on the state of the trigger circuit. The latter is controlled by the opposed outputs of channel signal rectifiers 7, 20, fed from valves 4, 17, respectively. The rectified signals are developed in the resistors 9, 22 connected in series between the grid of valve 27 and earth.

Title: Machine for generating helicoidal surfaces
IPC: B23F5/16
Filed: 1938-06-28
Abstract: 510,758. Shaping helical surfaces; gear-cutting. MILLER, E. W., and FELLOWS GEAR SHAPER CO. June 28, 1938, No. 19110. [Class 83 (iii)] In a machine for cutting helicoidal surfaces such as helical gears a reciprocating spindle carrying a pinion-cutter has means comprising selectively-engageable rack elements for rotating the spindle in either direction during its forward travel. In the application to cutting helical gears, the tubular work-spindle 11 has generating rotation imparted thereto by worm gearing 13 while the pinion-cutter 18 is mounted on a spindle 20 which may reciprocate and rotate in bearings in a saddle 17 movable by a screw 19 in horizontal guideways 15, 16. The cutter-spindle has circular rack-teeth 22 operated by a gear segment 23 carried by a rockshaft 24 to reciprocate the cutter through the work. Generating rotation is imparted to the cutter-spindle by a worm gear 241 driven by a worm 25 on a shaft 26 and connected to the spindle through sliding guides 27, 28. The worm 25 which is splined on the shaft 26 is mounted in bearings in a slide 31 having rack teeth engaged by a pinion 34 which is connected through shaft 35 and change gears 36 to a gear 39 engaged on opposite sides by rack bars 40, 41. The rock-shaft 24 carries a sliding element 45 having pinions 43, 42 coacting selectively with the rack teeth on the bars 40, 41. The element 45 is moved axially to cause one or other of the bars 40, 41 to be reciprocated by means of a control plunger 49 and pinion 46. In this way, during a forward movement of the spindle, the twisting spindle movement imparted through the slide 31 may be in either clockwise or anticlockwise direction according to which of the rack bars 40, 41 is reciprocated. This method of imparting helical movement to the spindle may be combined with the usual helical guides used for this purpose. In some cases a work spindle may be helically advanced past a stationary tool.
