Title: Improvements in coal mining methods and apparatus
IPC: E21C25/56
Filed: 1924-03-11
Abstract: 234,918. Tugwood, R. J., (Jeffrey Manufacturing Co.). March 11, 1924. Coal-cutting machines.-Coal is undercut by means of elongated cutter mechanism comprising a cutter chain travelling along a sectional guide frame with the capacity for adjusting itself to the length and contour of the face. After the coal is broken down, the cutter mechanism is employed for conveying the coal away to tubs &c. A variable number of frame sections 10<a>, 10<b> - - are coupled together by lugs 11 and pins 12 so as to have play horizontally and vertically, and support a cutter chain 14 driven through worm and chain gearing 23, 27 from a motor 22; each frame section has an arm 32 with a jack screw 34, whereby the frame section may be adjustably tilted so that the return flight of the cutter chain widens the cut. An anchor jack 29 passes through a slot in each arm 32 and is fixed between roof and floor; a rope 30 passes from a drum 29 driven by the motor 22 and over pulleys 44, 45, 46 to pass round pulleys 42, 43 on each arm 32 and a pulley 41 on each anchor jack to a fixed point, the rope being wound on the drum 29 during cutting, and thereby feeding the cutter frame into the coal. At the conclusion of the cut, the rope may be removed from pulleys 43 and re-adjusted round pulleys 41, 42 so that hauling in of the rope then returns the cutter frames. The coal may then be broken down, after which the cutter chain may be driven, and advanced as during cutting, to scrape the coal along the face to the mine cars 6. A shield to retain the coal may at this time be attached to the frame sections by lugs engaging apertures 51.
Patent GB-398215-A (GB)
Title: Improvements relating to gramophones
IPC: G11B17/16
Filed: 1932-03-02
Abstract: 398,215. Magazine gramophones. PARKINSON, W. R., 87, Tixall Road, Hill Green, Birmingham, and GARRARD ENGINEERING & MANUFACTURING CO., Ltd., Newcastle Street, Swindon. March 2, 1932, No. 6254. [Class 40 (ii).] Relates to magazine gramophones of the kind in which a pile of records is supported above the turntable, on to which they fall as they are automatically released in succession. According to the invention, the records are held by a number of supports which receive intermittent angular oscillations, each support comprising two record-engaging members so mounted on a common spindle that they are incapable of relative rotation ; the arrangement is such that in one position of the supports the pile is held up by engagement of the lowest record with one member of each of the supports whilst in another position this record is released and the remainder of the pile is held up by the other member. In the constructon shown, three record supports are provided, each comprising a pair of thin plates b, c secured to an oscillatory spindle d and separated by a distance equal to the thickness of a record. Each plate is cut away at a part of its periphery, the cutaway portion e of the lower plate being overhung by the longer part of the upper plate b and the longer portion of the lower plate c protruding beyond the shortened portion f of the upper plate. The short radial edge y of the plate b is bevelled to facilitate its entry between the two bottom records of the pile. Each spindle d carries a pulley h, the three pulleys being interconnected by a steel or other driving band i which is fastened to each drum. The band passes round guide pulleys j. To one of the pulleys is secured a crank disc k, connected by a link l to a driving disc m. This is adapted to be rotated by the turntable spindle through gearing o, n and a clutch t. The pile of records is initially supported on the projecting peripheral portions of the lower plates c, as shown. After a record on the turntable has been played, the pick-up arm q actuates mechanism (not shown) which puts the clutch t into action, whereupon the spindles d and the supports carried thereby are given a partial rotation. The lowest record of the pile is thus allowed to drop, being guided to the turntable by a 'rod r, whilst the remaining records are supported by the plates b. The pick-up arm has meanwhile been returned to the outer position. The record supports are then given a reverse movement, to their initial position, the pick-up arm is set in position for playing the fresh record on the turntable, and the clutch is disconnected. The supporting plates are formed with two sets of recordengaging portions, at opposite sides of the spindles d, the radial distance of one of these peripheral portions from the spindle being greater than that of the other. By reversing the positions of the plates on the spindles, the supports are thus adapted for holding records of larger or smaller diameter.

Abstract: 451,288. Indicating and locating faults ; current detectors. WARREN, T. R., Lynton, Granville Drive, Forest Hall, Northumberland. March 1, 1935, No. 6545. [Class 37] Faults on overhead power transmission lines are indicated on a subsidiary earth circuit which includes an earth connection separate from the main earth circuits, the subsidiary earth and fault indicator being in parallel with the main earth. The faultindicator may comprise a lamp 10 contained in a hinged casing having a peephole 76 for observing the burnt-out bulb. The stud connector 12 is unnecessary when metal poles or towers are fitted but with wooden poles it is connected to an earth wire, the connector 11 being joined to an earth spike in both cases. The resistance 6 of the subsidiary earth circuit is greater than that of the main earth 2. The fault-indicator in one form comprises a metal box 7 with an insulated stud 11 for connecting to the subsidiary earth, and, where fitted on wooden poles has a stud 12 for connection to the pole earth wire. The hinged cover 13 is provided with a keyoperated spring catch 15. In order to avoid line patrols, an insulated conductor running along the line section may be connected to each indicator which in this form operates to connect the conductor to earth through one or more sources of potential, the resistance to the fault being determined and hence its approximate location. If the conductor is lightly insulated it can serve additionally as an earth line, pilot wire or support wire.

Filed: 1922-03-06
Abstract: 201,587. Sproule, A. H., and Shaw, K. R. D. March 6, 1922. Compound piston pumps; regulating compression; heat of compression, absorbing. - In a compound air compressor the residual highly compressed gas remaining in the final stage at the end of the stroke and after delivery to the receiver is released into the initial stage after a charge has been induced therein, augmenting this charge, allowing a greater charge to enter the final stage from the atmosphere and from this initial stage, and lowering the temperature in the first stage. The compressor shown in Fig. 1 comprises a cylinder having at its low pressure end an inlet valve 6 and an outlet valve 7 leading to a pipe. 8 which conveys the air to a receiver from which it passes to the high pressure end. The high pressure end is formed with a substantial clearance space through which cooling tubes 13 pass, and with water spaces 11, 12, and is provided with an inlet valve 14 from atmosphere and an outlet valve 15. All these valves are automatic. Internal ribs may replace the cooling tubes. A casting 17, Fig. 4, secured to the cylinder is formed with a passage 16 connecting the clearance space with the other end of the cylinder. Mechanically actuated valves 20, 27 control the connection of the passage 16 with the high pressure clearance space and with a passage leading from the intermediate receiver; an opening 22 leads from this passage to the cylinder towards its low pressure end. In action, the low pressure space draws air in through its automatic inlet valve during its suction stroke, and at the end of this stroke the valve 20 is opened, allowing the contents of the high pressure clearance space to pass to the low pressure end. During the high pressure suction stroke, air is induced from the atmosphere through the automatic valve until at the end of the stroke the valve 27 is opened, alowing air compressed in the first stage to complete the charging of the second stage.
