Title: Improvements in or relating to potato harvesters
IPC: A01D17/10
Filed: 1935-09-06
Abstract: 449,058. Potato harvesters. NAAMLOOZE VENNOOTSCHAP TER BORG & MENSINGA'S MACHINEFABRIEK, Appingedam, Holland. Sept. 6, 1935, No. 24897. Convention date, Sept. 27, 1934. [Class 6 (iii)] The potatoes are lifted by an adjustable scoop 4 and pass on to an inclined endless chain grating 11 oscillated by eccentric toothed wheels 9, 12. Members 6 arranged over the scoop and actuated by cranks 8 assist the passage of the potatoes on to the grating: these members have spade - like lower ends, the lower edges of which may be covered with rubber, leather, or the like. The grating carries the material to an inclined fixed grid 13 along which it is swept by rubber cross strips 15 mounted on an endless chain 14: the inclined part of this grid leads to an horizontal portion 13a the bars of which are far enough apart to permit the potatoes to fall between them. Haulm and weeds are discharged over the end of the grid. The potatoes fall on a spring comb 21, the inclination of which can be adjusted, and are thrown therefrom into a grid cylinder 24. Remaining weeds and some of the potatoes fall from the comb on to an upwardly moving conveyer 23 which carries the weeds upwards while the potatoes roll downwards into the cylinder. A rubbercovered baffle 24<a> prevents potatoes from being thrown clear of the cylinder. A screw conveyer forces the potatoes laterally along the cylinder, removing the last traces of soil therefrom, to an elevator 26 that carries the potatoes to a trough 27. Any fine soil carried up by the elevator falls through a gap between the elevator and the trough. The parts of the screw conveyer and of the elevator which engage the potatoes are made of rubber. The trough 27 is carried by wheels on rails 28 so that when it is full it can be run to an inclined position at one side, its contents then forcing open a door and falling into a car below.

Title: Retractable belt
IPC: B60R22/35
Filed: 1964-06-18
Abstract: 1,006,966. Spring drums. B. F. MONROE. June 18, 1964 [Aug. 9, 1963], No. 25331/64. Heading B8B. [Also in Divisions A3 and F2] In a retractable seat belt assembly a spring drum supported by a member secured to a vehicle structure has a braking device mounted on the member which is operative for constantly restraining unwinding of the belt from the drum. The belt 28 is wound on the spring drum and round a braking roller 96 mounted to rotate in side plates 42, 44 (not shown) secured to the vehicle by a clevis 58. When the belt is withdrawn the roller slides downwardly in slots 92, 94 (not shown) in the plates into braking engagement with the flanges 68 of the drum. A pneumatic plunger 116 and cylinder 108 pivoted to the side plate 44 and to one end of the roller 96 has at the upper end of the cylinder an opening closed by a spring-urged poppet valve bored to allow controlled downward movement of the cylinder, to delay movement of the roller to arrest the drum until a length of belt has been withdrawn to permit the belt to be buckled to another part. When the belt is released the belt retracts under the action of the spring and the roller returns to its initial position out of contact with the drum flanges in which position it is held by a lug 138 on the belt end by leaf springs 102, 104 (not shown). In a modification the roller 96 is urged into constant braking contact with the drum flanges by downwardly acting springs and is held out of contact by the lug on the belt initially and then by the time delay cylinder. The belt is wound solely on the drum. In a further modification without a time delay device the belt and a tension member form a double ply wound on the drum the belt also passing round the roller 96 which is urged out of breaking engagement with the drum by a pair of leaf springs and is urged into braking engagement when the belt is withdrawn. The drum is released on slackening the belt by pulling a sleeve to which the tension member is attached.

Abstract: 1300774 Foldable umbrellas W BAUERMANN & SOHNE GmbH and ROSENKAIMER GmbH 28 May 1970 [7 June 1969 10 June 1969 5 Sept 1969] 25682/70 Heading A4P A telescopic umbrella of the type having a generally rectangular section in plan when folded Fig. 1 has a plurality of support units each formed of a rib 12, a stretcher 19 and an auxiliary strut 25 hinged respectively to a crown 15, a slider 21 and an auxiliary slider 24; and a telescopic shaft 10, 11 which supports the units, the crown 15 being transversely elongated and the sliders being of circular section so that each rib and strut or auxiliary strut does not lie in a plane parallel to the shaft axis. Since the sliders are circular the ends of the stretchers and hence sliding hinges 37 lie on a cirle, Fig. 11, concentric with the shaft and outer rib members 13 being hinged thereto have their tips on a circle also, which allows a normal symmetrical cover to be employed. The differing distances of the pivots of rib members 12 from the shaft are accomodated by differential telescoping of the ribs by an amount L3. The pivots on the main and/or auxiliary sliders may be evenly distributed about the peripheries or may be grouped in two clusters adjacent the long sides of the crown, Figs. 3 and 4 (not shown). The slots for the pivots are parallel sided except the end ones of the groups which may be wedge shaped, Figs. 7 and 9, (not shown). A spacer plate (39) Fig. 15 (not shown) on the slider (30) may be used to position the ribs when folded. A three section rib with an outer telescopic or folding member (43) may be employed when a three part telescopic shaft is used. Opening is initially aided by a rubber ring 23 on the auxiliary slider 24. The pivot slots in the sliders may all have mutually parallel sides Fig.3 (not shown) or may have mutually angled sides on those at the extremities of the groups Fig. 7 (not shown). Similarly the slots in the narrow-sides of the crown may be of mutually parallel wall form while those in the broad sides are wedge-shaped.

Title: Improvements in or relating to combined pressure medium brakes and electro-magnetic rail brakes
IPC: B61H7/08
Filed: 1933-09-16
Abstract: 430,727. Fluid pressure and electric brakes. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, Berlin. Sept. 16, 1933, No. 25704. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 17, 1934]. [Class 103 (i)] In a combined fluid-pressure brake and electromagnetic rail brake for vehicles, the rail brake is energized for a pre-determined period of time when an emergency application of the fluid-pressure brake is effected. The rail brakes 8 are raised by compressed air cylinders 7 supplied from a reservoir 3 through magnet valves 6, the reservoir being supplied from the main pipe 1 of the fluid-pressure brake system through non-return valve 2. The circuit of the valves 6 and of the coil of relay 12 controlling the current supply to the brakes 8 includes switches 10, 11, the switch 11 being normally opened by direct connection to the pipe 1 while the switch 10 is closed by the pressure in a reservoir 13 normally connected to pipe 1 through non- return valve 14 and a valve 15. When the pressure in pipe 1 is reduced only sufficiently to effect a service application of the fluidpressure brakes, the switch 11 is unaffected and the rail brakes 8 are not applied but an emergency reduction of the pressure causes the switch 11 to close to complete the circuit through valves 6 and relay 12 so that the rail brakes are applied. The fall of pressure in the pipe 1 also causes the valve 15 to disconnect the reservoir 13 from the pipe and to connect it to atmosphere through a restricted passage so that the switch 10 is opened after a time to de-energize the rail brakes.
