CLOCK-MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 467,354, dated January 19, 1892.

Application filed August 3,1891- Serial No. 401,582. (No model.)

To all whom, it may concern: In illustrating my invention 1 have shown Be it known that I, FREDERIO A. LANE, of a clock -movement which when running at New Haven, in the county of New Haven and the desired rate is found to rotate the arbor State of Connecticut, have invented a new A of the first wheel of its escapement-train 5 5 Improvement in Clock-Movements; and I do once in three hours. In order to convert that hereby declare the following, when taken in running rate of the train into time, I rigidly connection with accompanying drawings and attach to the projecting outer end of the said the letters of reference marked thereon, to be arbor a wheel B, having thirty teeth and cara full, clear, and exact description of the rying an intermediate wheel C of eight teeth. 10 same, and which said drawings constitute part This Wheel meshes into a cannon pinion D,

The accordance with my invention may assume, intermediate wheel C of eight teeth meshes 15 and Fig. 2 an enlarged sectional view thereof into and drives a socketwheel G, having on line a; 00 of the preceding figure. thirty-two teeth and adapted to be sleeved My invention relates to an improvement in over and rotate upon the cannon-pinion bethat class of clocks in which the going rate fore mentioned. It will be understood that of the pointers is not derived from a shaft of the minute-pointer, which is not shown, will 20 the escapement-train rotating once an hour be fastened to the outer end of the cannonand called the center shaft, but from one pinion, while the hour-hand, which is also not or more Wheels driven by the said train and shown, will be fastened to the outer end of adapted in size and in the number of their the socketwvheel.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a clock, the combination, with an escapement-train, of a wheel fixed to an arbor of the said train and carrying an intermediate wheel, a cannon-pinion meshing into said arbor-wheel, and a socket-wheel meshing into the said intermediate wheel, the said Wheels and pinion being adapted in the number of their teeth to convert the running rate of the said arbor into time, substantially as clescribed.

2. In a clock, the combination, with an escapement-train having one of its arbors rotating once in three hours, of a Wheel having thirty teeth fixed to the projecting outer end of the said arbor and carrying an intermediate wheel having eight teeth, a cannon-pinion having ten teeth meshing into the said arborwheel, and a socket-Wheel having thirty-two teeth meshing into the said intermediate wheel, substantially as set forth, and whereby the said Wheels and pinion convert the running rate of the escapement-train into time. In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
