Title: Improvements in and connected with conveyors
IPC: B65G23/00
Filed: 1924-10-07
Abstract: 245,216. Tugwood, R. J., (Jeffrey Manufacturing Co.). Oct. 7, 1924. Endless chain push-plate or scraper and trough conveyers; push-plates and scrapers, construction of; driving-gear; troughs; guiding; tensioning; standards. - In scraper conveyers having scraper arms extending laterally on each side of a single chain and in which the trough is made in flexibly jointed sections, the lower flight of chain is enclosed in and travels along a trough made in sections upon which the sections composing the upper trough are superposed and secured by readily detachable means which also permit of flexibly coupling the sections of the upper and lower troughs. The conveyer comprises a head or delivery section A, a series of intermediate sections C, and a foot section B. Each section C comprises a pan 3 which rests on the ground and a superposed trough 4 each preferably bent from single steel plates to the shapes shown in Fig. 7. Apertured lugs 9 at each end of a pan 3 register with corresponding lugs 10 on the trough 4 and receive bolts 11 which also pass through coupling plates 12. The bolts 11 fit loosely and allow considerable play, and the abutting ends of the sections are cut away at 14a to permit relative movement. Butt straps 13, 14 attached to one end of the.pan and trough project beneath the ends of the adjacent section and prevent leakage of fine material as well as ensuring proper alignment. A trough 16 similar to and connected with the trough 4 of the adjacent section is mounted on the head section 15 and has an inclined part and a horizontal overhanging portion. The conveyer chain passes round a sprocket 19 on an idler shaft 18, over a driving sprocket 20. and below an idler 41. A stripping plate 21 disengages the chain from the sprocket 19, and plates 32, 33 guide the chains into the pan. The shaft 22 is connected by sprocket gears with a shaft which is coupled by sprocket gears with the shaft of a motor. The chain is kept in engagement with the sprocket 19 by a block 40. The idler 41 and stripper plate 41a are provided in order that the chain may be driven in the opposite direction. The foot section B comprises a frame 34 provided with an inclined trough 39 and an idler sprocket 38. A wheel having a series of holes in its periphery is mounted on the end of the shaft carrying the sprocket 38. A crowbar is inserted in one of these holes to rotate the shaft in order to draw the slack of the chain from the pan 3 into the trough 4 thereby providing sufficient slack to permit uncoupling of the chain. The scrapers have vertical ribs 54, horizontal flanges 55, and aT-head 56 which receives the pintles of the chain. The chain comprises centre block links 42 and side bars 43 connected by pintles 44 having rivet heads at each end. The sections of chain are coupled by links 46, Figs. 10, 11, having lugs 47 engaging apertures in the block links. Pintles 48 having heads 49 at one end and grooves 50 at the other are passed through the links 46 and the lugs 47 are engaged by a locking bar 51 pivoted at 52.

Abstract: 1337374 Padlocks SARGENT & GREENLEAF INC 22 May 1972 [4 Nov 1971] 23916/ 72 Heading E2A  A key operable padlock 10, Fig. 2, has a casing 11 having sockets 14, 15, Fig. 4, therein for receiving legs 17, 18, Fig. 1, of a shackle 16 and has a central bore 25, Fig. 2, therein which receives a replaceable key lock plug 26, the latter being attached by screws 24b, 24b to a bolt 24, Fig. 1, which is movable into and out of locking engagement with notches 17a, 18a, Fig. 2, formed in the legs 17, 18 respectively of the shackle 16. An opening 27, Fig. 8, for a key is provided in the end of the padlock which is remote from the shackle sockets 14, 15 and a slideway 39, Fig. 1, for a slidable cover member 30 is formed at the other end of the padlock. The cover member 30 has an opening 40 through which the leg 18 can pass and serves to retain the key lock plug 26 in position when a pin 24e, of a rotatable bolt 24, is received in a slot 30A, Fig. 9, of the member 30. In order to substitute a plug 26 which is actuated by a different key, the shackle 16 is withdrawn and moved through 180 degrees so as to align the notch 17b of the leg 17 with the bolt 24. The original plug 26 is rotated by the key in the "remove-plate" direction shown in Fig. 8 so that the pin 24e of the bolt 24 can leave the slot 30A and allow removal of the cover member 30. The screws 24b, 24b are released and the replaced plug 26 is then connected to the bolt 24 by said screws 24b, 24b, Fig. 1. The shackle 16 may be retained within the casing 11 by a pin 19, Fig. 2, and the padlock may be provided with a shroud 49, Fig. 10.

Abstract: 906,830. Exhaust silencers. MURRAY, E., and MURRAY, K. July 7, 1961 [July 9, 1960], No. 24011/60. Class 7(2) An exhaust silencer comprises a valve member 1, Fig. 1, sliding over the exhaust pipe end, which is spring-loaded to close on a seat 7 when the engine is stationary and is opened by exhaust gas pressure, the movement of the valve member from its seat depending on the volume of exhaust gases passing through at any given time. A sound-absorbing lining 6 forms passages with the longitudinal ribs 3, for the exhaust gases. The tension of spring 4 is adjustable and a check wire 10 limits spring extension. In modifications a spring or springs may be disposed exteriorly of the valve member or a leaf spring or springs supports the valve member independently of the exhaust pipe. The seat 7 may be formed on a casing 9, Fig. 5, which is attached to the end of an existing exhaust pipe. In another embodiment the spring-loaded valve member 1, Fig. 4, may slide within an outer casing 11, on the ribs 3 which ribs may be omitted in a further modification.

Abstract: 976, 032. Photo-electric sensing devices. SPERRY RAND CORPORATION. June 18, 1963 [July 2, 1962, No. 24217/63. Heading G1A. [Also in Division G4] Unpolarised light from a source (not shown) is plane-polarised by a filter 12 before falling on a record card 16. Any light which leaks through a non-perforated region of card 16 is unpolarised, and the intensity of stray light falling on detector 36 is reduced by another filter 14 having its optical axis parallel to that of filter 12. Light which passes through an aperture in card 16 remains plane-polarised and is not attenuated by filter 14. In an alternative embodiment the axes of the filters are at right-angles to each other so that light only reaches the detector when no hole is present in the card, this arrangement being used when the material of the card has a high transmission coefficient.

Title: Combination selective radio programme self-starter, clock and calender
IPC: G04C23/00
Filed: 1944-12-08
Abstract: 587,638. Wireless receiving sets. LAN, G. Dec. 8, 1944, No. 24593. Convention date, April 15. [Class 40 (v)] A device for automatically switching on a radio receiver at a predetermined time comprises a shaft 8 and coaxial sleeves 9, 10 and 11 driven by clockwork 19, 20 and associated gearing so that pointers 2-5 indicate the time as minutes, hours, day of the week and day of the month on a dial 1 mounted on the front panel of the radio receiver. An outer sleeve 13 connected to the tuning condensers 14 of the receiver is rotatable to tune the receiver either by a manual knob and belt (not shown) connected to a pulley 55, or by a hand 7 which also serves to indicate on dial 1 the frequency to which the set is tuned. A further sleeve 12 has fixed on it a wheel 43 having a single tooth 44 which co-operates with the edge of a flange 41 on a wheel 40 which is free on sleeve 12 and is rotated once in 12 hours by a clock-driven pinion 23. Wheel 40 is biassed to the right by a spring blade 38 carrying an insulated contact 45 adapted to co-operate with fixed contacts 46, 47'in the supply mains of the receiver. In operation, hand 7 is adjusted to tune the receiver in the desired programme and hand 6 is set to the appropriate time, thus moving tooth 44 to the correct position. Wheel 40 is rotated by the clockwork so that, at the set time, recess 42 coincides with tooth 44, thus allowing wheel 40 to be moved to the right by spring 38 which, at the same time, completes the energizing circuit of the receiver at contacts 45-47. After an interval, the circuit is broken when tooth 44 rides out of recess 42.
