Abstract: 350,268. Recording-apparatus. MITCHELL, F. G., Albyns, near Romford, Essex. June 27, 1930, No. 19584. [Class 106 (iv).] Apparatus for recording the delivery of materials from bulk such as coal to locomotives comprises a plurality of type-wheels settable to any desired number and manipulative means adapted on operation to effect an impression of the number on a record-strip and to close the circuit of a motor to operate the coal feeding mechanism and advance the record-strip in accordance with the quantity being delivered. The manipulative means is adapted to be held in operative position and when released causes the switch to open and stop the motor, feeding mechanism, and record-strip. The strip is marked transversely in accordance with the quantity and the length of strip advanced is a measurement of the quantity delivered. As shown, a number of discs 1, Figs. 3 and 4, with numerals viewable through an aperture 3 in a casing 2 and with type elements co-operating with a record-strip 10, is mounted on a set of nested sleeves 4 operable by means of external finger discs 5 to set up the distinguishing number of the locomotive or receptacle being loaded. The coal feeding mechanism, which may be of the motordriven endless belt conveyer type, is connected by an endless chain 15 to a sprocket wheel 14 and through reducing gear 13e and coupling 13c drives a shaft 13b. This shaft carries a wheel 13 having dowel pins 13a engaging one of the discs forming a driving pulley 12 for the record-strip. The record-strip passes from a supply roll 8 over guide pulley 11 and pulley 12 to a receiver roll 9. The centre disc of the pulley 12 is roughened and the strip is pressed against it by means of a pressure roller 22, Figs. 1 and 2. The roll 9 is also driven from the wheel 13 by gearing 24 and a friction clutch 27. The outer ends of the rolls are freely mounted on pivots slidable in bearings to facilitate removal of the record-strip, the pivots being held in place by a spring-controlled cross-bar 36. The motor circuit is completed by the depression of a main operating lever 50 pivotally mounted on a shaft 49 an arm 48 on which displaces a spring-controlled rod 76b to close a switch in a housing 76a. Prior to the closing of the switch an arm 77 on the shaft 49 raises a cam-shaped bar 75 and a roller 74 thereon rocks a spring-controlled three-armed lever 71 and through a link 70 retracts an impression hammer 66 pivoted on a shaft 23. On continued movement of the bar 75 the cam part engages a roller on the shaft 72 and the bar is swung back to disengage the roller 74 whereupon the lever 71 is freed and the hammer is forced against the record-strip. The link 70 is connected to the hammer 66 by a spring 70x and a pin-and-slot connection to permit of rebound. The shaft 49 carries an arm 80, Fig. 1, to lock it in operative position by engagement with a holding lever 81, the parts being freed to return to normal position by the operation of a push-knob 84. Ink-ribbon mechanism.-Interposed between the type-wheels 1 and the record-strip 10 is an inkribbon 40, Figs. 1 and 2, mounted on spools 41, 41a secured to shafts 42, 42a carrying bevel gears 43, 43a one or other of which is adapted to be driven by a gear 44 or 44a on a longitudinally slidable shaft 45. Levers 52, 52a, pivotally mounted at 53, 53a are connected by a link 54 and are adapted to be actuated by projections on the ink-ribbon to effect its reversal a pin 55 on the lever 52 engaging a groove 56 in a collar 57 on the shaft 45. A notched arm 58 co-operates with a roller on the link 54 to hold the arms in adjusted position and a ball catch 64 co-operates with a grooved collar 63 to hold the shaft 45 in one or other of its positions. The ink-ribbon is advanced by a pawl 47, Fig. 4, on the arm 48 secured to the shaft 49 engaging a ratchet wheel 46 on the shaft 45.
