Title: Improvements in or relating to totalising mechanisms for use with automatic weighingapparatus
IPC: G01G23/18
Filed: 1930-07-14
Abstract: 352,262. Weighing-apparatus. AVERY, Ltd., W. & T. and GILBERT, A. S., Soho Foundry, Birmingham. July 14, 1930, No. 21217. [Class 143.] Sliding-weight apparatus.-Relates to an automatic totalizing mechanism for use in conjunction with automatic weighing apparatus, and is particularly suitable for use with wagon tipplers where the wagons are first weighed full and afterwards empty. According to the invention the drive to the totalizer is effected through two sets of gear trains each of which is capable of driving the spindle of the totalizer, one gear train serving to drive the spindle in a forward direction and the other in the reverse direction, the gear trains being alternately connected to the driving, spindle of the totalizer through a clutch mechanism which is actuated upon the rearward movement of a traversable poise forming part of the weighing mechanism to connect to the spindle the gear train required to drive the totalizer on the succeeding weighing operation. In the form shown, the totalizing counter 8 is driven by the usual shaft 3 connected to the mechanism of a power-operated poise 26. The shaft 12 of the counter is connected to the shaft 3 by two trains of gearing 9, 11 and 10, 13, 14 respectively, either of which may be coupled to the shaft 12 by means of a bell-crank lever 17 and two cone clutches 15, 16. The cone clutches thus impart opposite rotations to the shaft 12 and consequently add to, or subtract from, the readings of the counter. The bell-crank lever is connected by springs 27, connecting-rod 18, crank pin 19a, and gearing 19, 20 to a ratchet wheel 22. A weighted lever 24 loose on the shaft 21, carries a detent 23 engaging the ratchet wheel 22. The poise 26 carries a catch 25 resting against a pin 26a. When the poise moves from its zero position to weigh a loaded wagon the catch 25 passes over the weighted lever 24 without displacing it, and the weight is added to the counter 8 through the medium of the cone clutch 16. When the poise returns to zero the catch 25 rocks the weighted lever 24 and then releases it. During the return of the weighted lever, the detent 23 carried thereby, imparts a rotation to the ratchet wheel 22 thus disengaging the clutch 16 and engaging the clutch 15. The next weighing, viz. that of the empty truck, will now be deducted from the counter, and the subsequent return of the poise will again reverse the clutches in readiness for a loaded truck.

To permit break-back of the cutter-bar f when it strikes an obstacle, a mower hitched to a tractor by three links and connected to the lower links c by hitch pins e, is connected to the pin on the cutter-bar side through a plate n pivoted below the mower frame a on a vertical pin s attached to the frame so that the frame can pivot about the other hitch pin to the position shown in ghost lines when a stop w on the frame contacts a plate member v. To prevent break-back until an obstacle is struck, a ball or roller m mounted on the plate n is held in a depression to hold the plate n in the position shown. The depression is formed in the edge of a cam p on a plate q, pivoted at r on the mower frame a beneath the plate n and loaded adjustably by a compression spring t to detain the roller m until the cutter-bar f strikes an obstacle. Reversal of the tractor causes the roller m to run along the cam p and re-engage the depression. By varying the length of the upper link of the hitch, the pitch of the cutter-bar f is varied. A tie-link y between the lower links c may be lengthened or shortened by screw means to vary the angular position of the mower with respect to the tractor and thus adjust the lead of the cutter-bar. The Provisional Specification describes also a ball or roller held normally by two detents, each in a cam surface on one or the other of two plates pivoted on the mower frame.

Abstract: 702,959 Prepayment meters operable by coins of more than one denomination. WILSON GAS METERS, Ltd., G., JOHNSON, D. E., and WAKEFORD, J. E. May 12, 1952 [Sept. 22, 1951], No. 22236/51. Class 27 Coin action. The number of coins of a lower denomination which may be inserted in succession in a bi-coin meter is limited by a toothed wheel 25 which co-operates with a projection 30 on the plunger 11 by which the usual coin pocket is coupled to the appropriate coin wheel 21, 22. In the arrangement illustrated insertion of a penny depresses the plunger 11 so that a projection 20 on it engages between the teeth of a coin wheel 22 while the projection 30 engages teeth 27 on the wheel 25 so that the latter wheel is rotated with the coin wheel. After a predetermined number of pennies have been inserted an enlarged tooth 28 reaches the position illustrated in Fig. 2, so that it blocks full depression of the plunger 11 and consequently insertion of a penny. In this position, however, the plunger 11 may still be partly depressed by insertion of a shilling to engage the projection 20 between the teeth of the coin wheel 21: the projection 30 then engages a portion 31 of the tooth 28 so that the wheel 25 is turned with the coin wheel 21 to displace the tooth 28 from its blocking position. According to the Provisional Specification the invention may be applied to machines for vending articles: this subject-matter does not appear in the Complete Specification.
