Title: Improvements relating to conveyor guide tracks
IPC: B65G19/28
Filed: 1953-04-02
Abstract: 727,357. Endless conveyers. KELLER, H. April 2, 1953 [April 4, 1952], No. 9198/53. Class 78 (1). An endless conveyer framework is composed of units interlinked so as to form a series of articulated parallelograms a constituted by pairs of laterally spaced profile members b pivotally connected end-to-end and to transverse members c extended between the ends of each pair, the profile members affording upper and lower guides for the endless conveyer or its endless carrying elements. As shown, an endless scraper conveyer so formed can be laid in curves in the horizontal plane provided that its end sections lie substantially parallel. The hinge points d form the means for interconnecting the members band c. Each member c, Fig. 3, has a pair of pins p welded to it engaging in ears i secured to one member b and ears k attached to the adjacent end of the adjacent member b. The top and bottom casings f and e for the two superposed conveyer runs are formed separately for ease of assembly and pins pare tapered at both ends to allow of relative angular movement between the units in the vertical plane. The top casing is formed as a rail track for supporting waggons and is also provided with a conveying floor g which is pivotally mounted centrally on consecutive members c by pins t and has cranked side edges s for sliding engagement in a slot formed between the member c and the top casing f. In a second embodiment, Fig. 5, the pins p are not tapered and instead of being secured to the member c are secured to a skid 11 under the profile members, each of which are made in one piece, i.e. of E-section. The member c passes through slots 6 in the profile members of adjacent units and together with a pair of swinging fasteners 12 is threaded on each of the pins p. The adjacent units may thus be brought together and aligned laterally by the engagement of forked lugs 4, attached to the profile members, with the pins p, after which the swinging fasteners 12 are swung over latchtype fasteners of either form 9 or 10 to lock the adjacent units together. Relative angular movement between the units in the vertical plane is enabled by a loose fit of the swinging fasteners 12 on the pins p.

Abstract: 504,857. Fluid - actuated valves. THIMAN, G. March 25, 1938, No. 9240. Convention date, March 30, 1937. [Class 135] In an automatic liquidactuated valve, more particularly for use as a safety valve, of the type in which the valve member is in the form of a piston 7 which is pressed against a seat 4 by the force, for example of a spring 17 and is raised from the seat at a certain liquid pressure, the peripheral portion of the piston is elastic and is surrounded along the greater part of its length by a wall 9 which forms with the piston a chamber in which most of the static pressure of the liquid is maintained after the valve is open. The safety valve shown in Fig. 1, has an inlet 2 and an outlet 3 and comprises a disc 7 of soft rubber or the like clamped between rigid discs 5, 6. The disc 6 has a tubular extension 10 guided in an intermediate wall 14 clamped in the valve casing by screws 12 and a supporting plate 13. The latter separates the valve casing proper from a spring casing 16 housing a loading spring 17 which abuts a combined cover and spindle guide 21 and also a plate 20 adjustable on a threaded part 19 on the stem 18. The stem has a screw-driven slot 23 at its upper end and is pointed at its lower end for co-operation with the disc 6. A knee lever 24 engaging a nut 25 is provided for easing purposes. A gap is formed in the ring 9 opposite the outlet 3. A buffer disc 28 of rubber or the like is formed on the disc 6. The disc 7 may move within the wall 9 which may be merely the inside of the valve casing, with a certain amount of play to allow leakage between the two sides of the disc or ducts may be formed in the cylinder or the edge of the disc. For instance, the former may have four equally spaced vertical grooves. Grooves into which the material of the disc is pressed may be formed in either or both discs 5, 6. The Specification as open to inspection under Sect. 91 describes also a supply valve for flush tanks, Fig. 4 (Cancelled), controlled by a floatactuated auxiliary valve 30. The main valve comprises a disc 7 of rubber or the like clamped between rigid discs 5, 6 and moving in an actuating chamber 8 into which liquid passes through a duct 32 and whence it leaves through a duct 33 controlled by the auxiliary valve. The lift of the valve is adjusted by a screwed stop 35. This subject-matter does not-appear in the Specification as accepted.
