Title: Improvements in devices for connecting tubes, for instance scaffolding tubes
IPC: E04G7/14
Filed: 1955-03-09
Abstract: 769,477. Clamp fastenings. SPREEUWENBERG'S AANNEMINGSBEDRIJF N.V., P. March 9, 1955 [March 13, 1954; Feb. 9, 1955], No. 6984/55. Class 44. [Also in Group X] A clamp for connecting two scaffolding or other tubes 21, 22, Fig. 1, at right angles to one another comprises two rigidly connected or integrallyformed socket halves 1, 2 arranged at right angles to one another, each of which carries a complementary socket half 3 hinged to it, the means for clamping each complementary pair of socket halves around the tube consisting of a connecting link 7, one end of which is pivoted to one socket half, for instance, to the free end of the hingedly mounted socket half 3, so as to turn about a rotatable eccentric pin 17, Fig. 3, and which is adapted to be brought into engagement at its free end with the socket half complementary thereto. The pins 17 have squared end portions engageable by a spanner for rotation of the pins 17 to tighten the clamp. As described, the pins 17 are mounted between pairs of spaced plates which form the hingedly. mounted socket halves 3. Each link 7 has at one end a hole, Fig. 3, engaged over the pin 17 between the spaced plates, and at the other end is of T-shape having two wedge-shaped teeth 23 which engage selectively with teeth formed on a pair of projections 9 on the socket halves 1, 2, enabling adjustment to be made for different diameters of tubes 21, 22. Rotation of the pin 17 is limited by a stop 20 formed on a washer 18 carried by the squared end of the eccentric pin 17. In a modification, Fig. 4 (not shown), the free end of the connecting link 7 engages the socket half 1 in a non-adjustable manner.

Abstract: 898,616. Tempering chocolate and the like. SOLLICH, H. Feb. 27, 1959 [Sept. 2, 1958], No. 7012/59. Classes 28 (1) and 129. [Also in Group XXIX[ In apparatus comprising a water-jacketed enrober 1 and a water-jacketed tempering unit 2, 2a for chocolate or the like, are provided conduit means to connect a hot-water source to both water jackets and a cold-water source to the tempering unit jacket and circulation control means for these conduit means whereby during " warming up " hot water only is circulated to both water jackets and during " normal running " hot water is circulated only to the enrober jacket and only cold water to the tempering unit jacket. As shown, control means 3 comprise a control piston 4, with an annular recess 4a, moving in a cylinder 10 to which are connected hot water feed pipe 11 and hot or cold water return pipe 12 from the jacket of cylinder 1 and the hot water return pipe 13 from the jacket of conduit 2. Cylinder 10 has a cold water drain 16 and a used hot water drain 14 leading to a heating tank 15 from which the hot water passes to the jacket of tempering unit 2. Piston 4 is moved by rod 17 either manually by a handle 18 or automatically by means of a piston 19 secured to rod 17 and moving in a cylinder 20. This piston is operated by mains water controlled by solenoid valves 25, 26 operated by a pyrometer or thermostat 27 set for the required temperature. Initially, valve 26 is opened, Fig. 1, and hot water flows through both jackets, pump 29 pumping the hot water from container 15 to the jacket of the enrober. When thermostat 27 reaches the required temperature, valve 25 is opened and valve 26 is closed to produce the normal running position, Fig. 2, in which cold water is supplied to the tempering unit jacket when magnetic valve 30 opens, which may also be controlled by thermostat 27. Further control means for heating unit 28 may be provided which maintain the hot water temperature at 40‹ to 60‹ C. during " warming up " and at e.g. 34‹ C. during " normal " running.

Abstract: 453,563. Pen, pencil, &c. holders. GERSTER, E., 24, Luisenstrasse, Berne, Switzerland. March 11, 1936, No. 7409. [Class 146 (iii)] A holder for a writing element is formed of a thin-walled tube having at least one inwardly directed projection, which owing to the thinness of the tube wall is resilient so as to grip the writing member in the holder against displacement and rotation. The tube 1, of avional, anticorrodal, or aluminium alloy or of cellulose or a synthetic resin product is provided with three longitudinal ribs 3 of circular cross-section, which grip a pencil 5, or a plug 7 between which and the wall of the tube a nib 4 is held. The plug is bored at 10 so that the pencil can be expelled by means of a rod, or may be resilient and of U-shaped cross-section. Either or both ends of the tube may be cut off obliquely. A hexagonal sleeve to prevent rolling may be secured to the end of the tube, which may itself be of polygonal cross-section. The pencil can be reversed when not in use and the space between pencil and plug can be used for storing nibs &c. The nibs 3 may be of different depths at the two ends to hold different sizes of pencil, and may end conically to facilitate insertion of the pencil. One or two ribs only may be provided to grip a square pencil. The outside of the tube may be matt, polished, or ornamented.
