Title: Improvements in or relating to striking and chiming gears for synchronous-motor electric clocks and the like
IPC: G04C21/08
Filed: 1937-02-04
Abstract: 489,855. Striking and chiming mechanism. BROWN, T. A., and PERRIVALE CLOCK MANUFACTURING CO., Ltd. Feb. 4, 1937, No. 3283. [Class 139] Striking and chiming mechanism for synchronous-motor and like clocks comprises two distinct differential gears of the epicyclic type, one 30 operatively connected with the striking gear and the other 32 with the chiming gear, two driving wheels 36 fixed each to one of the sun wheels of the differentials meshing directly one with the other, while change-over means 68 common to both differentials and controlled by the time train is arranged selectively to render the differential gears operative for actuating the striking and chiming gears. A release lever 52 pivoted at 54 is arranged to be lifted by the usual quarter and hour lifting ears 56, a catch 62 pivotally mounted on the lever 52 being raised thereby to engage its hooked portion 84 with a lug 86 on a biassed control lever 64 pivoted at 66. Upon release of the lever 52, the catch 62 descends and rotates the control lever 64 to bring arm 68, Fig. 2, mounted on the same spindle 66, into the path of an abutment 46 on the planet carrier 40 of the differential gear controlling the chiming mechanism. A pair of planet wheels 43, 45, are in mesh with a continuouslydriven sun-wheel freely mounted on a spindle 32 and each meshes with one of a second pair 42, 44, which are in mesh with another sunwheel coaxial with the first and keyed to the spindle 32. The arrest of the planet carrier 40, therefore, causes the spindle 32 to rotate and this drives the chime train including the quarter disc 12. A forked lever 70 is lifted as a pin 74 fixed thereto rises out of a notch 15 in the rotating disc 12, and a second pin 76 engages the edge 82 of the catch 62 to disconnect the latter from the control lever 64, a lug 81, meanwhile, engaging an abutment 92 to present the release of the control lever until the chime is completed and the pin 74 descends into the next notch 16. At the hour, an extra rise 94 on the quarter disc causes the hour rack 18 to be released by the engagement of a lug 80 on the upper fork of lever 70, with the rack hook 22 pivoted at 23. Upon completion of the chime, the control lever 64 is allowed a greater anticlockwise movement before reaching the stop pin 93, which movement brings the arm 68, Fig. 2, into the path of the abutments 46 on the planet carrier of the strike differential and initiates striking which is carried out in known manner. Provision may be made for striking the half hour, and a silent lever 96 coacting with the lever 52 may be provided. If the differential spindles 30, 32, tend to rotate during the idle period, convenient stop means such as one-way pawl-and-ratchet mechanism may be provided. Specification 437,609 is referred to.

Filed: 1924-02-19
Abstract: 233,079. Linotype & Machinery, Ltd., and Jakeman, J. W. Feb. 19, 1924. Gripper mechanism.-Sheet-gripper mechanism for the impression cylinders of printing-machines, of the kind in which the same spring pressure is employed to hold the grippers open and closed when not under the influence of the mechanism which rocks the gripper shaft, is constructed so that the turning moment exerted by the spring instead of varying harmonically as in known arrangements, decreases rapidly to zero as the shaft is rocked to open the grippers, and then attains a value in the opposite sense just sufficient to complete the rocking of the shaft and to retain the grippers open. By this means lighter springs can be used, and a more uniform and higher running speed of the press can be attained. The gripper shaft 1 is fitted with a tumbler cam 2 with cam recesses 3, 4, operated by pins in known manner, and the grippers co-operate with pads 6 on a shaft 7. The grippers are normally held closed by the action of rollers 18, carried by pivoted arms 8 connected to spring-pressed rods 13 guided by fixed eyebolts 16 secured to webs arranged in the hollow impression cylinder 11. The rods 13 are controlled by springs arranged between partly spherical washers 15 and adjustable collars 17, and the rollers 18 act on cams 19 on the shaft 1, the cams being formed with abutments 20 and being so shaped that the line of application of the spring pressure decreases rapidly in distance from the axis of the gripper shaft as the grippers open, but the line does not pass far beyond the zero or dead centre position.
