Title: Earth scraping machine with an elevating conveyor
Inventor: JOHNSON CHARLES MATTHEWS
IPC: E02F3/64
Filed: 1965-07-22
Abstract: 1,065,585. Endless conveyers. JOHNSON MANUFACTURING CO. July 22, 1965, No. 31317/65. Heading B8A. [Also in Division E1] An earth scraper has a scraping blade and a conveyer for lifting excavated earth into a bowl. Endless chains of the conveyer pass round shaft mounted driven sprockets and idler rollers, both the sprockets and the rollers comprising two or more segments which are bolted together with annular backing plates so that the segments can be removed and replaced one at a time without removing the chains or shafts. The conveyer is mounted for vertical movement by means of a link (112) pivoted to both the conveyer (at 110) and the scraper frame (at 114) and has spring means (128 or 192) for urging the conveyer towards the ground over guide means (148) which can guide the lower end of the conveyer into any of three positions depending on the quantity and size of the excavated earth.

Filed: 1938-10-31
Abstract: 520,755. Packing. CHALMERS, J. W., and MOLINS MACHINE CO., Ltd. Oct. 31, 1938, No. 31439. [Class 94 (i)] Relates to a packing or wrapping machine of the kind in which articles, such as batches of cigarettes, are moved in succession past feeding and wrapping devices, detectors being provided at various points of the machine to detect and eject defective packages. According to the invention, manually controlled means is provided for actuating the ejector, in addition to the automatic means, to enable the operator to eject selected articles during the continued working of the machine. The invention is shown applied to a. machine of the kind described in Specification 508,466 in which batches of cigarettes are wrapped and are finally deposited on a conveyer which carries them to devices for completing the packing. The batches of cigarettes, as they,fed from a hopper, pass beneath a detector of known construction, and this detector is connected in series with an electric battery 48, an electromagnet 36, and a switch 124 which permits the detector to energize the magnet only when cigarettes are passing beneath the detector. Adjacent to the magnet 36 is a rotating disc 49 which is provided with a number of studs 66 that operate the ejector, when the magnet is energized, in the manner described in the prior Specification. In parallel with the ejector 24 is a press-button switch 45 and a make-and-break switch 46. By closing the switch 45, the operator is enabled to energize the magnet 36 and eject from the machine any selected package without stopping the machine. The switch 46 is operated by cams or other moving devices in the machine, and is provided to ensure that the ejector works in correct relation to the other moving parts of the machine.

In a seal between relatively slidable parts, such as a piston 11 and its cylinder 19, in which two sealing rings 15 of resilient material, such as synthetic rubber, are located in series in grooves 13, 14 in one of the members and pressure build-up in the space 23 between the rings is relieved through vents 22 in at least one of the rings, the vents are controlled by one or more non-return valve members 20 attached to the ring. The valve members 20 may be bonded to or integral with the ring and may be slit radially to form separate flaps for each vent. Backing rings of nylon, synthetic polyamide resin sold under the Trade name " Akulon," resin impregnated material, polytetrafluoroethylene, synthetic rubber sold under the Trade name " Kel F " or glass fibre held together by a plastic substance such as polytetrafluoroethylene may be fitted behind the rings to prevent them extruding into the space 23. The backing rings may be cup-shaped, the sealing rings being complementarily shaped. In a modification, Fig. 4, the sealing ring comprises a rubber part 26 with vents 22, and an L-section part 27 of harder rubber, rubberized fabric, nylon, " Akulon " or polytetrafluoroethylene bonded to or having an interference fit on the first part so that its longer arm sealingly contacts the cylinder 19 whilst its shorter arm 28 acts as a non-return valve for the vents 22.

[Also in Division F2] A selector valve for use in gas chromotography comprises a stationary member 4 having a flat seat with three flow ports 1, 3a, 3b at the comers of an equilateral triangle and a fourth port 2 equidistant from the other three, and a rotary valve disc 5 rotatable on the seat and having one channel 10 for interconnecting any two of the first three ports and a second channel 11 for interconnecting the fourth port and the remaining one of the first three ports. As applied in known manner to elution chromotography, a small volume of sample fluid is entrained in an inert carrier gas and directed in one position of the valve from the inlet 1 through a separating column connected at 3a, 3b, to the outlet 2. The column contains a partitioning agent which has different affinities for the various sample components so that they elute from the column at different times and are passed to a detector. In another position the high boiling components which normally take a long time to pass through the column, can be back-flushed from the entrance of the column by reversing the flow, or in the third position the column is by-passed.

Bobbins P are fed by endless conveyer 14 and fall down shoot 14A on to rotating rubber disc 16, which flings them on to circular plate 15 revolving at a lower speed, both disc and plate being inclined. Plate 15 feeds the bobbins nose-to-tail along the gap which lies between the plate and the surrounding hopper 17, until they are discharged from the plate through opening 31. They then fall on to endless conveyer 35 which conveys them to a check weighing machine past a photo-electric light beam 47. The beam causes actuation of gate 40 which governs intermittently the discharge of the bobbins through opening 31 so as to regulate the rate of feed to the weighing machine. Additionally, plate 15 runs upon three wheels 36, 37, 38 (not shown) so that when the weight of bobbins on the plate is excessive the plate tips to actuate a micro-switch to stop the supplying of the bobbins thereto by the conveyer 14.

Abstract: 172,312. Civilingenieure R. Seyfferth & H. Hansen Ges. Dec. 6, 1920, [Convention date]. Electromagnetic switches.-In an electromagnetic switch operated from a distance by a small current, a contact-member is moved in opposite directions corresponding to the on and off positions of the switch by similar strokes of a core produced by successive energizations of a single coil. In the form shown in Figs. 1 to 4, a pressbutton switch c operates at a distance an electromagnetic switch f, f<1>, f<2> by energizing its solenoid a, whereupon an extension l of the core rocks a catch m, pivoted at i, from the position shown in Fig. 1 to that shown in Fig. 2. The weight h carries the catch over the dead-centre to the position shown in Fig. 3. When the pushbutton c is released, the core falls some distance until it is caught by the arm g. When the button is again depressed the parts take up first the positions shown in Fig. 3, then those shown in Fig. 2, and, when again released, the core falls completely to the first position, Fig. 1. The locking device may be arranged at the side of or below the core. In the arrangement shown in successive positions in Figs. 7 to 10, a projection p on the end of a link n extending from the upper end of the core is guided in a heart-shaped cam groove, the turning points of which are laterally so displaced in relation to the turning points of the inner edge that the projection, in the repeated reciprocating movements of the armature. comes to rest alternately in the upper and in the lower depression of the heart-shaped groove and thereby causes the main switch to be closed or opened. Reference has been directed by the Comptroller to Specifications 434/96 and 153,787.
