CLARKE OONWELL, OF LARGHMONT, NEW YORK, ASSIGNOR TO HELEN M. OKANE CONWELL, OF LARCHMONT MANOR, NEW YORK.

CLOCK.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed December 6,1905. Serial No. 290,653.

To all whom it may concern:

Be it known that I, CLARKE OONWELL, of Larchmont, in the county of Westchester, State of New York, have invented certain new and useful Improvements in Clocks, of which the following is a specification.

This invention pertains to certain new and useful improvements in clocks, and relates more particularly to that class of clocks which are adapted for striking ships time.

The invention has for its object the production of a clock of this character which will strike the hours and half hours in close imitation to the usual bell strokes by which time is indicated on shipboard.

A further object is to provide means which will cause the initial stroke of the striking hammer to always occur upon the first portion of a double stroke.

A further object is to provide means whereby a double stroke is secured with a single hammer.

A further object is to provide an improved pin disk for operating the striking hammer, together with means for automatically placing said pin disk into and out of operative relation with said hammer.

A further object is to provide pin mechanism which will automatically return to a normal position after each operation of the striking mechanism.

In carrying out my invention I provide a gear meshing with the striking train, said gear being keyed to a suitable shaft and provided with spaced apart openings to receive the pins of a pin disk loosely mounted on the same shaft, said gear and pin disk being normally held separated by any suitable means, such as a spring. Suitable means, operated by the hour hand shaft, is provided to move the pin disk toward the perforated pinion against the action of the separating means, whereby the pins of said disk protrude through the openings in the gear, this movement being timed to occur simultaneously with the operating of the striking train which rotates said gear. Upon completion of the striking operation the disk and gear are automatically separated, and said disk reversely rotated to its normal position by any suitable means, such as a spring or the like.

The invention will be hereinafter more fully described and particularly pointed out in the claims.

In the accompanying drawingr-Figure 1 is a front view of a clock with the face removed, illustrating my invention. Fig. 2 is an edge view thereof. Fig. 3 is an enlarged edge view of the pin disk and its adjuncts. Figs. 4, 5 and 6 are details.

Referring to the drawing, 10 designates a gear keyed to a shaft 11 and meshing with a pinion 12 of the striking train which latter may be of any'preferred construction. The shaft 11 is also provided with a second gear meshing with the main driving gear 13 of the striking train. Mounted on shaft 11 adjacent gear 10 is a pin disk 14 which is free to rotate on said shaft and provided with a plurality of pins 1.5 arranged in pairs and adapted to protrude through openings 16 arranged in the gear 10. Said gear and pin disk are normally separated by any suitable means, preferably a spring 17 as shown. Mounted loosely upon shaft 11 is a cam gear 18 provided with a cam 19 which is adapted to engage a similar cam 20 also loosely mounted on said shaft 11 and interposed between the cam gear and the disk 14. The cam 20 is free to reciprocate upon the shaft 11 but is prevented from rotating thereon by means of an arm 21 engaging the shaft 22 of the pinion 12. The gear 18 "is rotated by a similar gear 23 seemed to the sleeve which carries the minute hand, said sleeve being rotated in the usual manner by the time train. By this arrangement the cam 19 is completely rotated once in each hour. In this connection it will be noted that I do not claim any specific time train and therefore have not illustrated the same in detail. The cams l9 and 20 are each provided with double cam faces 24, whereby the pin disk 14 is moved into engagement with the gear 10 once every half hour. The pin disk 14 is provided with a stop 25 which is held normally in engagement with the winding shaft 26 of the striking train by means of a coil spring 27.

The operation is as follows:The gears 18 and 23 be ing of the same size the cam 19 acts upon cam 20 to move the pin disk 14 into engagement with the gear 10 once every half hour. Simultaneously with the lateral movement of the disk 14 the striking train is released by the releasing mechanism R which may be of any preferred form common to striking clocks, whereupon gear 10 is free to revolve under the action of the driving gear 13. In this manner the pins will trip the lever L of the striking hammer. The pins being arranged in pairs will cause said hammer to operate with a double stroke to correspond to the stroke of nautical bells which are struck in pairs. After the stroke has been made, the onward movement of the minute hand sleeve and gear 23 carries the gear 18 and its cam forward so that the cams l9 and are in such position as to permit lateral movement of the cam 20 and disk 14, under the influence of spring 17, whereby the pins 15 are disengaged from gear 10. Just as soon as said disk 14 is disengaged from the gear 10, the disk is reverscly rotated under the influence of spring 27 until the stop en gages shaft 26, said stop being so located as to always stop the disk 14 with its pins opposite the openings 16 in gear 10, the striking train being so constructed that the gear 10 always stops with its openings in the same relative position.

The advantages and operation of my improved clock are apparent from what has been said. It will be observed that by arranging the hammcr operating pins in will insure that the initial stroke o the hammer will always occur upon the first portion of the double stroke. It will also be noted that by this arrangement I am enabled to secure the double stroke with a single hammer. It will be further observed that I have provided simple and eflicient means for automatically placing the pin disk into and out of operative relation with the striking hammer, and have insured the returning of the pin disk to its normal position. It Will be particularly observed that the parts are so arranged as not to be affected by pitching or rolling of the vessel in rough Weather.
