25,705. Richards, G. L. Nov. 8. Feeding webs. - In apparatus for the sale of stamps, tickets, &c., a reciprocating arm 5 disposed on one side of a grooved table 1 feeds the strip x along the table by means of teeth 6 engaging the perforations between the stamps, while a second arm 10 disposed on the other side of the table is provided with a cutting- member 12, which, when the feed - arm has reached the end of the table, co - operates with the teeth to sever the foremost stamp along the line of perforations. The arms 5, 10 are controlled by springs 7, 13 respectively, and are pivoted on a spindle 5b mounted in a carriage 11 which is reciprocated along a base 20 by any suitable means. Projections 8 on the arm 5 co-operate with fixed cam pieces 9 so as to bring the teeth into and out of engagement with the strip at the required times, the projections being lifted on to the upper surfaces of the cams during the return movement by the engagement of the spring 7 with a projection 5c on the arm. A pivoted spring 4 slotted for the passage of the teeth 6 serves to hold the strip during the return movement of the feeding arm, but is lifted during the forward movement by the engagement of a projection 17 on the arm with the tail 20 of the spring. The severing arm 10 is operated by spring-controlled levers 14, the arms 15 of which co-operate with rollers 16 mounted in the side plates. When the strip is exhausted, a roller 21, which normally bears on the strip drops into a recess 23 in the table, thereby withdrawing a rod 24 and releasing a lever 25 which actuates mechanism (not shown) for closing the coin slot.
