Abstract: 673,831. Pigeon-timing apparatus. SMITH & SONS (ENGLAND), Ltd., S. Feb. 28, 1950 [Feb. 28, 1949], No. 5375/49. Class 106 (iv). Recording - apparatus particularly for the timing home of racing pigeons wherein a record is made of the time of insertion in the apparatus of tokens such as rings into a pocketed drum and wherein the records are sealed until officially opened, comprises a base-plate with the time-piece mounted in a compartment at the front end, the drum rotatable about a vertical axis near the rear end and the web take-up spools and printing mechanism also supported thereby, a removable cover for the plate and parts mounted thereon having an open end engaging a wall of the front compartment and its rear wall apertured to expose a part of the drum periphery, the pockets being disposed in from the periphery. A drum 31, Fig. 2, is provided with 10 recesses 32, arranged in two staggered rows with a double gap labelled " open " and " full," Fig. 4, each recess being adapted to receive in turn a thimble 33 containing a pigeon ring. The drum is driven a step for each revolution of a spindle 19, Fig. 2, keyed to a handle 69 and provided with a cog 17 meshing with a cog 16, Fig. 3, fixed to a driving member 25 with single tooth 26 for co-operation with a maltese cross ring 38 attached to the drum 31, pawl 18a and ratchet 18 preventing reverse rotation. The cog 17 is located in a recess in a base-plate 10 and the ring 38 surrounds a member 28, Fig. 2, located by a flange 29 on the spindle 19. The member 28 and also a member 43 have flanges 30, 44 entering circular grooves 35, 36 in the bottom and top ends respectively of the drum and extending into the lower and upper rows of recesses 32 to key into circumferential grooves 75 in thimbles 33. The member 43 forms a bearing for the spindle 19 and is attached to a casing 42 enshrouding the drum 31, while a cover 13 with recess 68 to accommodate the handle 69 covers the base-plate 10 and mechanism mounted thereon fitting at its front end into a slot 14 round a housing 11 for clock mechanism. In order to place the cover 13 in position the drum must be in position with the " open " section aligned with openings 45, 64 in the casing 42 and cover 13 so that a gap in the drum flange 40 is aligned with an opening 46 in the casing 42 and the key and keyway in the handle 69 and spindle 19 must be longitudinally disposed with respect to the cover 13, a roller 67 on an arm 66 on the cover 13 can then pass through the opening 46 and will, upon rotating the drum a step, roll on the inside of the flange 40 to lock the cover in position until the drum has been advanced a complete revolution. The flanges 30, 44 for keying into grooves 75 in thimbles 33 have gaps 76 aligned with the openings 45, 64 so that when a recess 32 with stub 34 comes opposite the openings a thimble containing a pigeon ring may be inserted, the flange 30 or 44 will then enter its groove 75 when the drum is advanced, thus locking the thimble in position and carrying it behind the casing 42. Paper feed. A gate member 47, Fig. 5, carries a spool 48 for record paper which passes through the gate to a take-up spool 22a on a spindle 22, Fig. 3, with cog 23 fixed thereto which is driven from a mutilated cog 21 toward the end of each revolution of the spindle 19, pawl and ratchet preventing reverse action. Ink-ribbon mechanism. Resilient members 49, 60, Fig. 5, support an inked-ribbon 51 which passes through the gate in front of the record paper. Printing dies. In front of the ink-ribbon is a fixed die 53, Figs. 5, 6, with date or day, hour, minute and second indications embossed round holes 54, 55, 56, 57 in which four corresponding hands of a clock move and make a record on the paper when it is pressed thereagainst by a moving die 59. A set of indicators show the time through a window in the housing 11. Impression mechanism. The moving die 59, Fig. 5, is urged towards the fixed die 53 by a spring 61 and is coupled to a trigger 62 which co-operates with a cam 63 fixed near the top of the spindle 19 so that as the spindle turns the cam 63 depresses the trigger 62 to load the spring 61, while the drum is advanced a step to lock the thimble in position and thereafter releases the trigger so that the die 59 snaps forward to impress the time on the record paper which is then advanced at the end of the spindle rotation and exposes the record through openings in the top of cover 13.
