66 66 66 greater or less space of time as required. The opening and closing are effected by means of catches or triggers, which act 66 on a lever fixed to the dial of the clock. The opening of this trap permits the introduction of a supply of numbered markers, or any other controlling medium, which fall into receptacles "fixed to a horizontal circular plate, worked by the same escape"ment as the clock. These receptacles are numbered so as to correspond with the figures on the dial. In this way the "markers fall into the receptacles which correspond respectively "to the hours at which they were introduced. This apparatus "acts as a check on the going out or coming in of workpeople, "and for other similar purposes." [Printed, 4d. No Drawings.] A.D. 1857, December 4.-No 3012. GRIZARD, JOSEPH.-" Improvements in watches, and in the means of or for winding up and setting watches.” 66 1st. "The construction of an improved watch," in which “the "motor is a simple spring (shaped something like the hammer of "a fire-arm)" acting on the arm of a toothed quadrant so contrived as to obtain a continuous equal or regular action. The quadrant "is in gear with a pinion free to turn on the axis "of the centre wheel, and carrying a very small ratchet con"trivance; the motor spring has on its longer branch a roller,” which acts on the curved arm of the quadrant. The winding up is effected "by means of a piece or bolt projecting a little beyond "the edge of the case, to which is attached a stud which presses 66 or acts on one of the arms 99 of the quadrant, so that by the pressure of the projecting piece acting on this stud the watch "is wound up. The hands are set by means of a stud on the pendant, to which a rod is fixed, retained in position by a spring, and carrying a serrated or toothed pinion, which on drawing back the stud gears into a double set of teeth under "the return minute wheel." 66 2nd. The winding up of watches in which a barrel is used. Instead of having a key square, the barrel arbor is formed with a ring notched into two teeth" having two spaces with a central stud, on which the key fits." "The same appliances and construction may be applied to keys for setting the hands." [Printed, 6d. Drawing.] A.D. 1857, December 10.-No 3049. HODDELL, JAMES.-" An improvement in watches." This invention "consists in the application to watches of two mainsprings instead of one, as in watches of the ordinary "construction." 66 The drawings show two barrels, in each of which is a mainspring, the said barrels being side by side. The fusees are of the ordinary construction, "excepting that the threads are cut in a contrary direction;" they are connected in the usual way with the barrels of the mainsprings respectively. "The works of the "watch differ in no essential respect from the works of ordinary "watches, excepting that I employ an additional wheel and "pinion in the train of wheels between the springs and balance "wheel or escapement." In an ordinary watch the fusee is geared to and turns the centre wheel carrying the minute hand. In using two springs, it is preferred to make the fusees gear into a pinion, a wheel on the axis of the said pinion gearing into and driving the centre pinion. By this arrangement a watch may be made to work eight days. The spring barrels may be made to drive the works "without "the intervention of a fusee." The two springs require to be wound up separately; they act jointly and simultaneously upon the works. 1st. "Improved modes of working the independent seconds."— Only one mainspring and train are used to work the independent seconds. On the arbor of the escapement is placed a ratchet wheel "which acts by means of a lever, spring, and catch upon a ratchet wheel placed upon the staff or shaft of the cannon "pinion, the boss of the said wheel carrying the independent "seconds' hand." 66 In another arrangement, the independent seconds hand is put in action "by placing it upon or connecting it to the boss of a "ratchet wheel, acted upon by a catch, spring, and lever, the "latter having an intermittent motion by means of the vibration of a pin on a lever, operated upon by a ratchet wheel on the “ shaft ce arbor of the fourth wheel pinion, it can also be pro"duced from the third wheel pinion by the same arrangement or by a ratchet, small, and lever from the third and fourth " wheel pinions or shafts.” 2nd. “Improved chronometer escapements, having circular " pallets,”—An angular lever and spring locks and unlocks the wheel instead of a detent, the said angular lever and spring " being acted upon by a small roller having two small stones < placed so as to form a slit or fork, or one stone slit so as to form " a kind of fork or opening."

(Provisional protection only.)—“Improvements in winding up "watches which have not fusees or chains." “It has always been an objection to watches made without “fusees and chains that their winding the contrary way to all “other English made watches made them liable to be often put “out of order. We propose remedying this by using an extra " ratchet wheel, gearing it with the key ratchet wheel at present "used; by this means we can wind up in the same way as English "watches which have fusees and chains, and thereby prevent the possibility of these watches being put out of repair by winding "the wrong way. By this construction we can make these "watches much flatter or thinner than any English watch hitherto made, and consequently make them more suitable for the pocket. We therefore claim as our invention the application "of an extra ratchet wheel by which we accomplish the ends already described." 66 [Printed, 4d. No Drawings.] 1858. A.D. 1858, January 20.-N° 94. NIXON, CHRISTOPHER NUGENT." Improvements in the ap"plication of screw power, such improvements being applicable "to steering apparatus, capstans, windlasses, cranes, winches, “and other mechanical purposes.” This invention comprises the use of endless screws for the above-mentioned purposes. In the ordinary method of applying this invention, pinions are placed on the ends of screw spindles, and a larger wheel is used to turn them. When, however, this invention is applied to clocks and watches, three equal wheels are preferred. The centre wheel is “ attached to the barrel,” “ it being also attached to the minute "hand. The spindle of the worm wheel (which, in this case "revolves) has twelve teeth, and is attached to the hour hand.” One revolution of the centre wheel carries the minute hand once round, and at the same time effects a complete revolution of the screws carrying the hour hand one-twelfth round, which is equivalent to one hour. "Another method with one screw is as follows:-From and “attached to the barrel" "proceeds a single spindle, bearing a 66 screw thread, and to the end of which is fixed the minute hand. “The screw part of this spindle passes through a hollow wormed "wheel, having twelve teeth in the internal circumference, and "which is attached to the hour hand. By the revolution of the "above-mentioned barrel” “the same result is produced as "before described." The specific application of this invention to clocks and watches is not described in the Provisional Specification. [Printed, 10d. Drawings.] A.D. 1858, February 9.—No 238. WELLS, JOHN.-" Improvements in watch cases." This invention "consists in the particular construction whereby "the open-faced watch can be readily converted into a hunting "watch, and on the contrary, the hunting watch can be as readily converted into an open-faced watch.” 66 "I form the watch in the manner of an ordinary hunting “watch, with this exception, that I remove as much of the bottom 65 or dome that encloses the face of the watch, so as to expose the "whole of the dial. The part so removed or rather made sepa66 rately is fitted to the ring or bizell remaining of that dome, so as to snap into its place in manner similar to a watch glass. "The watch is in fact made with two bizells, the under one for A.D. 1856, February 13-No 278. JOHNSON, EDWARD DANIEL—“An improved construction ** of chronometer case.” The object of this invention is to render the chronometer case air-tight. “The glass bizzel is made to fit or slide on,” “and it is fur“nished with a lip which laps over the box beyond the bottom “of the slip or junction, and rests against a shoulder.” The ordinary glass is cemented into its place, and a vulcanised indiarubber ring is interposed between the cover and the box. The cover is then pressed down and kept in this position by screws. The ratchet winding key fits on to a cylindrical nose, which passes "through a stuffing box in the bottom of the case opposite "the winding square, and is kept out of contact with the square by a coiled spring that surrounds the nose. The stuffing box, spring, and nose of the key are enclosed in a bag formed by a disc of vulcanised india-rubber, the edges of which are secured to the bottom of the case by a ring and screws. "The nose of the key or winding instrument passes through an opening in this india-rubber disc or sheet, the edges of which 66 opening are secured between clamping rings. 66 66 وو "In order to bring the nose of the key or winding instrument "into a position to act, it is pressed forward on to the square of "the fuzee by means of the key handle, and when in that " position an axial motion is given to the key handle, and the "fuzee square is turned.” [Printed, dd.
