Abstract: 425,682. Counting- apparatus; recording- apparatus; momentary-contact switches. PALIN, J., (trading as DALYTE ELECTRICAL CO.), Deco Engineering Works, West Row, North Kensington, London. Sept. 13, 1933, Nos. 25383/33 and 26211/34. [Classes 106 (i) and 106 (iv)] [See also Group XXXVII] Apparatus for registering and/or recording quantities of coal delivered to a locomotive comprises counting mechanism actuated by an electromagnetic device, the circuit of which is rapidly closed and opened by a switch having stationary and movable contacts, the latter being operated from the delivery mechanism for each definite quantity of coal delivered. In the embodiment described, means are also provided for switching-in the delivery-mechanism motor, for printing the number of the locomotive concerned and for zeroizing the counter after each operation. When the apparatus is used, a lever 50 secured to a shaft 51 is moved and rocks a shaft 65 by a pin-andslot connection 63. The shaft 65 carries three pairs of contacts which complete the circuit to the motor of the delivery apparatus and energize the circuit containing the counter - actuating electromagnet and its controlling switch. Quick - acting switch. Each stroke of the delivery apparatus causes an oscillation of an arm 24, Fig. 15, carrying a pawl 22 advancing a ratchet wheel integral with a pinion 19 engaging a pinion 18 connected to a star wheel 15 which causes contacts 8<a> pivoted at 10<b> momentarily to engage fixed contacts 11<a>, the contacts being reopened by the swing back, due to gravity, of the contacts 8<a>. Counting mechanism. The contacts 8<a>, 11<a> close the circuit of an electromagnet 4, Fig. 1, the armature 6 of which pivoted at 7 rocks clockwise a lever 39, 41 pivoted at 40 to raise, by a pin-and-slot connection 44, a rod 45 carrying a pawl 48 which advances a wheel 34, Fig. 4. The wheel 34 is connected by pins 34<a> to a pinion 80 gearing with a pinion 81 connected to a pinion 87 and to the units disc 90. The pinion 87 engages a pinion 84 connected to a star wheel 93 with which engages a justifying pawl 102, Fig. 5. Transfer mechanism. A single-toothed disc 100 is secured to the units disc and engages a star wheel 94 connected to a gear 85 engaging a pinion 88 connected to the tens disc 91. The tens justifying pawl 102 also engages the star wheel 94. Zeroizing mechanism. The operating lever shaft 51 has an arm 54 which reciprocates a slide 56 carrying a projection 116 which, on the return stroke, rocks a lever 114 to raise a link 112 and rock the shaft 103 carrying the justifying pawls 102, these pawls thus being withdrawn from the star wheels 93-95. A link 110 is lowered by the shaft 103 to rock a lever 109 secured to a shaft 106. The lever 109 is connected to a slide 108 having cams which engage behind a head 36b on the shaft 36 of the wheel 34 and slide this shaft to the left to disengage the wheels 80, 81. The shaft 106 carries arms 105 having rollers 107 which engage heartshaped cams 96-98 connected to the wheels 84-86 and return the cams, wheels and numeral discs to zero. Recording the counter reading. When the slide 56 is being moved by the return movement of the operating lever 50 a projection 164 on the slide rocks a lever 157 pivoted at 159 to a platen 151, an ink ribbon and a record strip 146 against the numeral discs. The record strip 146 is advanced from a roll 147 to a roll 148 by a ratchet wheel 188 secured to the roll 148 and advanced by a pawl carried on a lever 187 oscillated by an arm 191 of a lever 191<a> actuated by a cam 194 on the slide 56. Recording the number of the locomotive. Segments 121 are adjusted by knobs on shafts 128 until the locomotive number is indicated by numerals secured to the segments and viewable through apertures 120. The shafts 128 are connected to the segments by bevel gears 129, shafts 130 and gearing 131, the segments having internal teeth 124. The shafts 128 carry pinions 134 engaging pinions 135 secured to shafts 136, Fig. 14, having star wheels 137 with which contact detents 138 on levers 139. When the locomotive number has been printed a lever 142 is turned to move a rod 141 to the left to swing the levers 139 against spring action so that the detents 138 are moved away from the star wheels and the segments 121 are returned to zero by gravity. Plates 122, Figs. 1 and 4, are secured to the segments 121 and carry type denoting the locomotive number. This number is printed in a line with the number recorded from the counter, the printing being effected by a platen similar to the platen 151 and actuated by the slide 56 on the first stroke of the lever 50. Printing a particular symbol. When several quantities of coal are delivered to different parts of a tender, the lever 50 is operated after each delivery to print the loco. number and the quantity, but the segments 121 are not zeroized until after the delivery of the last quantity. A symbol 171 is then printed on the record strip between the last quantity and the number. The symbol is provided on the frame 170 and the strip is pressed against it by a platen operated by a lever 173, Fig. 13, actuated by a rod 176 moved to the right by a connection from the rod 141 which effects the zeroizing of the segments 121. The rod 176 swings a lever 182 to the right to block the slide 56 and so lock the lever 50. Ink-ribbon mechanism. A shaft 204 is advanced by a pawl 206 carried on an arm 206a secured to the shaft 115 of the lever 114 oscillated by the slide 56. The shaft 204 drives the ink-ribbon spool 196, Fig. 4, through bevel gearing 200. When the ribbon 150 is all wound on the spool, a projection on the ribbon rocks anticlockwise a lever 218 about its pivot 216 to lower a distance member 220 between a rib 214 secured to the slide 56 and a collar 208 on the shaft 204. The next movement of the slide to the right moves the shaft 204 in the same direction, disengages the bevel wheels 200 and engages bevel wheels 201 so that the ribbon is re-wound on a spool 197. The shaft is detained by a latch 213 engaging a collar 209 secured to the shaft. When the spool 197 is fully wound, a projection on the other end of the ribbon rocks a lever 217 to insert a distance member 219 between the rib 214 and a collar 207, whereby the ribbon direction is again reversed.
