IMPROVEMENT IN PROGRAMME-CLOCKS.

Specification forming part of Letters Patent No. 143,230, dated September 30, 1873 application filed May 10,1873.

To all whom it may concern:

Be it known that 1, SAMUEL F. EsTELL, of the city of Chicago and State of Illinois, have invented a new and useful Improvement in Programme-Clocks, of which the following is a complete specification, reference being had to the accompanying drawings.

My improvement embraces a modification of myinventions relating to programme-clocks, for which Letters Patent of the United States were first granted to me January l1, 1870, No.

98,678, and has for its object the locating of the programme-wheel beneath the movements77 in a more convenient and accessible position, instead of at the rear ofthe move- Fig. 2 is a attached to a sleeve, I, which latter is rigidly Y 'secured to a plate, I), at the back of the clockcase. On the sleeve, to which wheel m is attached, is a wheel, H, gearing with a pinion on the upright shaft e. A pinion on the upper end of shaft e gears with a wheel on the minute-wheel shaft F. A connection is thus made between the movement ofthe clock and wheel m, by which the latter is operated, regard, ofcourse, being had to the sizes of said wheels and pinions, so that wheel m shall receive a proportionate speed.

The programme-wheel, in its position herein described, operates the striking movement of the clock by means of a tripping-lever, C. Le ver C is pivoted at D to a bearing secured to the back of the case, and, as shown by Fig. 2, forms an angle to accommodate it to both the wheel m and thedrop-wire. The end of 'said lever C, in contact with wheel m, is so shaped as to be tripped by the tripping-wires or springs of wheel'm. The other end of said lever C is attached to the drop-wire c of the clock, and thus at each passage of a tripping-spring, beneath the end of lever C, the strikingtra-in is putin motion.

Having thus fully described my said invention, what I claim is In combination with a programmewheel, the lever C and drop-wire a, operating substantially in the manner described, and for the purpose set forth.

SAMUEL F. ESTELL.
