The drum 2 is secured to the frame, and has slots 68, 57, Fig. 7, for the introduction of the fish f and spikes g respectively. The rolling- elements comprise a rod 18, mounted on a revoluble sleeve 6, and a curved member 17, extending from the sleeve 7. A disc 14, having two notches for a spring-controlled pawl 13, and a gear-wheel 15 are mounted on the sleeve 6, and a disc 12, having a notch for a spring-controlled pawl 11, and an arm 65 are mounted on the sleeve 7. The members 17, 18 serve as grippers and are operated intermittently, singly or simultaneously, accordingly as the fish is to be fed between the grippers, rolled or spiked and ejected, by the engagement of a mutilated gear-wheel 16 and a projecting pin 66 thereon with the gearwheel 15 and the arms 65 respectively. When the fish is inserted between the members 17, 18 the wheel 15, being adjacent to a toothless part of the wheel 16, remains at rest. The teeth b then operate and move the gripper 18 towards the gripper 17 which is held stationary by the pawl 11. The members 17, 18 having gripped the fish, rotate in unison and the fish, being wound around them, is pressed by arcuate plates 3 spaced from the drum 2 by springs 4. The springs 4 are arranged so that the radial distance of each plate 3 decreases in the direction of rotation, the tightness of the rolling thereby being assured. The rolling been completed, the other toothless portion of the wheel 16 becomes adjacent to the wheel 15 and the grippers come to rest for spiking and ejecting. The teeth a then operate and, in conjunction with the arm 65 and pin 66, return the grippers to the receiving position. Spices, such as pepper seed, are supplied to the entering fish from a hopper 36, by means of a pocketed roller 35 and a channel 38. The spike magazine comprises two rollers 19, 20 having longitudinal grooves on their peripheries which receive spikes g from a hopper. The rollers 19, 20 are interconnected by gear wheels and are intermittently rotated by a pawl 30, on an arm 27 mounted on a disc 25, which engages notches in a disc 26.

Addition to 385,384. [Class 40 (iv)] The single - motion selector described in the parent Specification is adapted for the merging of traffic represented by any pair of received digits by connecting the two corresponding groups of, outlets in multiple to a single group of outgoing lines, a discriminating signal being sent forward or not over a seized line to effect the necessary divergence at 'the succeeding switching stage. The selector has two sets of double-ended speaking and test wipers, the two ends traversing corresponding arcs of terminals in succession, and two double-ended wipers CC, DS concerned respectively with the numerical control of the selector and the transmission of discriminating signals. Impulses are received by a pair of relays P, Q, both being operated after each odd impulse and neither after each even impulse, and the selector advances after the odd impulses to successive stopping positions marked in the arcs of wiper CC. Wiper-switching is controlled by relays P, Q according as the received digit is odd or even. A discriminating earth signal is applied to the positive wire when the connection is extended over one of two multipled groups of outlets over wiper DS, the relevant terminals of which are cross-connected to terminals TE 1-3, TE1 being used when the two multipled groups are reached over the same set of wipers and TE2, 3 being used when they are reached over different sets, the operation in the latter case being dependent on the condition of relay P. The last test terminal of each group is connected to relay LC, and earth applied over wiper DS is utilized to operate an overflow meter over the positive wiper in the case of a " live " group or relay C(iii) via terminal SG in the case of a spare group, this relay connecting up NU tone instead of the busy signal.
