Patent GB-435338-A (GB)
Title: Improvements relating to slicing machines
IPC: B26D7/02
Filed: 1934-07-13
Abstract: 435,338. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H., Aden Road, Ponders End, Middlesex. July 13, 1934, No. 20549. [Class 28 (ii)] An end-piece holder arranged for angular correcting movements, is angularly operated by a lever pivoted to the frame supporting the holder and connected to the holder, a portion of the lever cooperating with an abutment which swings the lever during the general feed movement and thereby swings the holder. In Figs. 1, 2, the endpiece holder K is pivoted at 26 in a U-shaped frame having slotted lugs 23, 24 whereby it is secured to one clamp post H, swinging of the frame being prevented by a pin 28 engaging a hole in the frame extension 25. A locking-pawl 40 is urged by a spring in the tube 44 into its locking position, and is released, when desired, by a handle 42. A bell-crank lever 30, 31, pivoted at 32 to an extension 29<1> of the holder frame, has a ball end 35 which slides in a part-cylindrical slot 36 in a member 37 pivoted at 38 to lugs on the back of the holder K. Inadvertent swinging of the holder is prevented by a friction washer 27 on the pivot bolt 26, the pressure on the washer being adjusted by turning the bolt 26. When the holder is initially set angularly, according to the taper of the substance, the arm 30 of the lever either rises or falls, and is restored to its mid position in which the holder K is parallel with the slicing plane, by contact, during the general feed, with either one or the other of the members 33, 34 which are secured to the usual substance support M. In a modification, two levers are mounted on a common pivot on the holder frame, and have ball-ends which engage separate pivoted part-cylindrically slotted members on the holder. The arrangement is such that, in the initial angular setting of the holder, the lower end of one of the levers is projected towards the slicing plane, whilst the lower end of the other lever is retracted from the plane. The projected lever end contacts with a stop of the substance support M and effects the corresponding angular correction as the general feed progresses. In another modification, a lever is pivoted on a vertical axis on the frame and a ball end thereof slides in a horizontal guide in the holder. The free end of the lever contacts with one or other of two inclined cam faces to produce the angular correction. If angular correction in one direction only is required, one stop, or lever, may be dispensed with. The ball end 35 may be replaced by a pivoted cylindrical end, or by a roller. Specifications 337,572, [Class 28 (ii)], and 433,819 are referred to.

Filed: 1939-07-15
Abstract: 534,816. Trucks with lifting platforms. AERO ENGINES, Ltd., and HALLIDAY, G. F. July 16, 1939, No. 20645. [Classes 78 (iii) and 78 (iv)] [Also in Group XXXIII In a wheeled truck, with an hydraulicallyactuated lifting platform operated from the propulsion plant of the truck, the platform is connected to the chassis through linkage, and the hydraulic jack or jacks actuating the linkage is operated through a selector valve from a pump driven by the motive power of the truck. In use the truck is run beneath a goods-laden platform and is used to lift the goods therefrom, transport them and set them down on a receiving platform in a new location. Fig. 1 shows a three-wheeled truck with a single driving and steering wheel in front, and a lifting platform 20 having depending members 24 supported on cross shafts 23 through the agency of links 22. An hydraulic cylinder 17, pivoted at one end to the main vehicle frame and at the other end to links 21, raises the platform by swinging links 21, 22 when the piston is forced outwards. A connecting rod 25 imparts similar movement to the links at the rear of the platform. The vehicle engine inside the casing 10 drives the continuously running pump 9 which draws fluid from the reservoir 11 and delivers it through the pipe 16 to the cylinder. The control valves, which are operated by the flexible cable 13 from the setting- and-retaining mechanism 14, 15 on or adjacent to the steering column, are situated inside the reservoir as seen in Fig. 4. The hand-gear 14,15 rocks a member 40 so that plungers 35, 36 force the ball valves 29, 30 off their seats to varying extents. In the position shown both ball valves are free, and the pump 9 draws from the reservoir through the passage 26 and delivers through the passages 27 and 45 thence raising the ball valve 29 and passing to the cylinder through the pipe 28. When the platform is fully extended, excess fluid passes back to the reservoir through the safety valve 37. By depressing rod 36 the valve 30 is raised from its seat so that continued action of the pump delivers past this valve back to the reservoir. Lowering of the unloaded platform is obtained by forcing valve 29 from its seat and allowing escape through passages 28, 45 and 46. Lowering of the loaded platform is obtained by forcing valve 29 further downwards until the enlarged part of plunger 35 restricts the passage 28.
