10,988. Defauw, T. May 10. No Patent granted (Sealingfee not paid.) Timing pigeons.-A race-timing apparatus, which may also be used as a tell-tale for watchmen &c., is constructed so that the sheets on which the time is recorded can be seen without opening the apparatus, and the apparatus records the day, hour, minute, and second of the time of return of the pigeons &c. In the use of the apparatus for recording the return of a pigeon, the pigeon ring is placed in a cell 53, Fig. 4, a number of which are formed in a disk to which a chemically prepared sheet, or a sheet provided with an inking-ribbon &c., is attached, the disk being intermittently rotated, so that various parts of it come into contact with type-wheels 10, 7, 8, 17, Fig. 1, upon which the sheets are pressed by means of a rubberfaced hammer or hammers 28, Fig. 2. The hammer is operated by means of a crank 41 on a shaft, which is provided with an arm 39, normally acting on a bar 34, connected to an arm 33 on a shaft. On rotation of the shaft 40, the arm 39 moves the arm 33 against the action of a spring barrel 36 connected with the bar 34 by a chain 35 ; at the end of a semi-revolution, the arm 39 snaps past, .the bar 34, the arm 33 returns quickly, and a pin 38 connected to a disk 37 on its shaft acts on an angle-lever 43, which depresses the hammer on to the type-wheets, and on to a bar 11 arranged at the same level as the tops of the peripheries of the type-wheels. This bar 11 makes marks between the hour and minute indications. The hour-wheel 8 is marked with four distinctive sets of numerals from 1 to 12, so as to indicate the a.m. and p.m. ,hours on two consecutive days, and the wheel 8 is provided with two pins which move the day-wheel 7 one division per day. The wheels are driven by ordinary clock-work, which also drives hands 13 which move over an enclosed dial to indicate the time. The clock may be stopped by a spring-controlled lever 20, which can be made to engage a pin 19 on the seconds' wheels, and stop it in such a position that the wheel 10 indicates sixty ,seconds. The lever 20 is normally held out of the path of the pin 19 by means of a lever 23 fixed to the same spindle as the lever 20, the lever 23 being' held by a notch in a lever '25. The clock is set going at a standard time, and then the cover is closed by a seal to prevent access to the stop mechanism. The spindle 40 is formed with a ratchet-wheel, to prevent its being moved backwards, and also with a snug 46 which, at each revolution, moves a wheel 47, geared to the disk upon which the sheet is mounted, so that the disk advances a distance equal to that between two cells 53 at each actuation of the shaft 40. The disk is covered by a mica cover 55, Fig. 4, provided with a trapezoidal aperture, and the outer cover in which this disk moves is also of mica or glass, and ia provided with a similar aperture which permits writing to be inscribed on the portion of the sheet that is stamped with the time.
