Title: Improvements in and relating to the synchronisation of clocks
IPC: G04C11/00
Filed: 1920-06-26
Abstract: 167,060. Hubbard, W. S., Parsons, I. H., and Ball, A. E. J. June 26, 1920. Synchronizing.-Clock pendulums are contrclled and synchronized by means of the usual periodic electric impulses being arranged to .adjust automatically the tension of a spring &c. or the effective length of the pendulum. Fig. 1 shows an arrangement in which the pendulum B which has been given a losing rate has pivoted thereto a flat leaf spring A while a rack C forms parts of the armature of an electromagnet D operated periodically. Normally the rack C engages with the leaf spring A after the latter has passed over half its length, and the resulting tension gives the pendulum an acceleration to compensate for the losing rate. If however the pendulum is slow, the movement of the armature causes the leaf spring to engage the rack at an earlier point of the swing of the pendulum and consequently increased tension is given to the leaf spring A, which tension further accelerates the pendulum. If desired, the spring A may be pivoted to a fixed part of the clock and .an abutment of the pendulum may contact with it at or towards the end of its swing. The leaf spring has attached thereto a lever which coacts with the rack in such a manner that the tension of the spring varies according to whether the pendulum is fast or slow. Fig. 3 shows an arrangement in which the leaf spring A is caused to act on the pendulum by means of the lever B<3> pivoted at B<4>, the position of the lever B<@> being adjusted by means of a rod B<9>, cam B<7> and wheel B<6> in conjunction with the armature C. The gaining rate imparted by the spring A with a medium deflection is compensated by a manual lowering of the pendulum bob. According as the pendulum is slow or fast, the pendulum will be swinging to the left or right respectively at the moment of the periodic impulse, and consequently the wheel B<6> will be given an anticlockwise or clockwise movement which adjusts the lever B<3> and so vary the tension of the spring A. In another arrangement, the movement of the wheel B<6> adjusts a weight arranged on the pendulum to vary its effective length, the spring being dispensed with.

Title: Improvements in or relating to mechanism for controlling the operation of friction gear driven machines
IPC: B65H7/18
Filed: 1925-07-07
Abstract: 247,827. Toronto Type Foundry Co., Ltd., (Assignees of Olson, A.). March 11, 1925, [Convention date]. Stopping and starting arrangements.- In manually and automatically controlled disengaging and braking means for friction gearing driving machines such as the sheet-feeding machine described in Specification 240,760, a wedge member separates the driving-roller and driven disc and at the same time brakes the disc. The driving-roller g is driven through gearing f<1> from a main shaft f and is adjustable on its shaft so as to drive at variable speed the driven disc h, which is carried on a shaft c' sliding in its bearings under the influence of a spring c<3> to maintain driving- contact of the gears g, h. In the machine shown, the shaft c<1> drives the forwarding-roller c transferring sheets to the forwarding-table e composed of rollers e<1> supplying a folding, printing or like machine. The sheets are fed to the roller c from conveyer belts a by a suction-roller b. The rollers e<1> are driven by bevel gearing e<2> from the main shaft f. The wedge member i is provided with a friction face j<1> and is pressed between the disc h and a stationary but adjustable pivoted abutment k to disengage the disc from the roller g against the action of the spring c<3> and to bring the disc to rest. The wedge j is supported by a lever l on a rock-shaft l<1> and is counterbalanced by a weight l<6>, the rock-shaft being connected by linkage l<2>, l<3>, l<4> to a rock-shaft m provided with a lug m<2> and connected by linkage o, o<1>, o<2>, o<3> to a rod p adapted to be slid manually to force the wedge j to disengagement position. Automatic disengagement is effected when more than one sheet at a time is fed to the roller c by the use of a detector-wheel d carried loosely on the shaft of a wheel d<1> which co-operates with the roller c in the feeding operation and is pressed into contact with the sheets by a spring d<2>. A cam surface d<0> on the wheel d engages an extra sheet being fed, so that the wheel is rotated and jammed against the sheets by the cam action and during its rotation brings an arm d<3> secured thereto into engagement with the lug m<2> on the shaft m to force the wedge j to disengagement position. A spring l<5> bears against a. collar on the rockshaft l<1> to maintain the wedge j normally out of contact with the face of the disc h when it has been returned to the inoperative position by the action of the spring c<3> and the weight l<6>. Specification 242,538, [Class 100 (i), Feeding and delivering webs &c.], also is referred to.
