f SHIPS-BE'LLS CLOOKs Application filed June24,

To all whom it may concern Be it known that I, FREDERICK WEHINGER, a citizen of the'United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in. ,Ships- Bells Clocks; and I do lierebydeclare the following, when taken in connection with the accompanying drawings and the char acters of reference markedthereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in Figurerl, a View in front elevation of a ships bells clock constructed in accordance with my'inventiomthe' time-train of the clock being omitted I j Fig. 2, a view ofthe clock in left-hand side elevation, showingthe pin-wheel.

Fig. 3, a detached perspective view of the pin-wheel.

Heretofore ships bells clocks have gen erallybeen furnished with a rack-and-snail striking mechanism modified as required for sounding ships .bells andopen to the objections of being complicated and there fore expensive to construct, and diiiicult to adjust. The object of my invention is to produce a ships bells clock in whichthe sounding of ships bells is. efitected by extremely simple, inexpensive, and reliable means. ith these ends in 'view, my inven tion consists in a pin-wheel carrying pins arranged singly and in pairs, in combination with a count-wheel having its deep notches arranged to complement the arrangement of said pins.

My invention further consists in certain details of construction as will be hereinafter described and. pointed out in the claims. V

In carrying out my invention, as herein shown, I employ a pin-wheel 2 (Fig. 3) having a series of pins set into its outer face in accordance with the plan of ships bells, under which plan the twenty-four hours of a day are divided into six watches of four hours each, the division of the watches Specification of Letters Patent. Patented Sept. 13,1921. I

of the watch.-v The next succeeding group of pins consists of a pair of pins 5, 5 followed a single pin 5, and stand for three bells, denoting the expiration of the first hour and a half of the watch. The

pins 5, 5, and 5 are succeeded by a group consisting of two pairs of pins 6, 6 and 6, 6 sounding four bells, denoting the expiratio-n of the second hour of the watch.

The two pairs of pins, 7, 7, 7, 7 and the singlepin 7 stand for five bells; the three pairs otpins 8,8, 8, 8, 8, 8 stand for six bells; the three pairs of pins 9, 9,9, 9,9, 9'

and the single pin 9 stand for seven bells; while the four pairs of pins 10, 10, 10, 10, 10,10, 10, 10 stand for eight bells and complete the watch. V

In conjunction with a pin-wheel having gle group of pinsupon the pin-wheel, but

this is not imperative, as thefnumber of groups of notches in the count-wheel may be-variedas desired so longas the pin-wheel and count-wheel are geared in the proper ratio. I prefer, however, to provide the count-wheel with a plurality of groups of notches, since such a construction permits the count-wheel to be geared so as to re volve very slowly, which is highly important in eight-day clocks, where a rapid rotation of the count-wheel would beundesirable; Furthermore, the employment of a relatively large count-wheel facilitates the arrangement of the count-hook so as to avoid interference with other parts of the movement.

As shown, the pin-wheel 2 and count wheel. 11 are co-axially mounted upon the winding-arbor 14:, the pin-wheel 2 having a hub 15 carrying gear 16 meshed into by a gear 17 on the main pinion-stafif 18 of the strike-train, which is not fully shown. The count-wheel 11 is driven by a pinion 19 upon the staff 18, these wheels and pinions being proportioned so that the pin-wheel is geared to travel three times as fast. as the. count-wheel.

The pins of the pin-wheel co-act with a hammer-operating finger 20 in a rock-shaft 21 mounting the hammer-wire 22 of the hammer 23 which strikes the bell 2a. On the other hand, the teeth 12 and deep notches 13 of the count-wheel co-act with a count-hook 25 hung upon a rock-shaft 26 operated by a two-notched cam 27 on the third wheel-staff 28 of the strike-train.

The particular mounting and operation of the pinand count-wheels will be varied in accordance with the size and character of the clocks in which my invention may be embodied, my invention being characterized by a pin-wheel provided with pins arranged singly and in groups in accordance with the characteristic sounding of ships bells. By arranging the pins singly and in groups in the pin-wheel, I am enabled to effect, with a single hammer, a snappy striking of ships bells with those sensible intervals between the pairs of bells and the single bells necessary to enable the time to be accurately told, while by driving the pinwheel at a higher speed than the count-wheel, I am enabled to revolve the count-wheel with suflicient slowness to permit the free action oi"; the count-hook in its deep notches,

which can, of course, be no wider than the spaces separating its teeth, from which it follows that if the count-wheel is revolved too rapidly, the count-hook is liable to foul in its deep notches.

I claim:

l. A ships bells clock having a striketrain including a pin-wheel, pins mounted therein singly'and in pairs, in accordance with the divisions of ships bells, and a-hammer-operating member acted upon in sequence by all of the said pins, whereby, by arranging the bells singly and in pairs, compensatory spaces are provided between them for the reception of the hammer-operating member and mis-striking avoided.

2. In a ships bells clock, the combination with a pin-wheel, of pins mounted therein singly and in pairs in accordance with the divisions of ships bells, a count-wheel having its notches arranged on the principle of ships bells, a single hammer actedupon in sequence by all of the said pins, a count-hook coacting with the count-wheel, and means for driving the pin-wheel at a relatively greater speed than the count-wheel.

3. In a ships bells clock, the combination with a pin-wheel, of pins mounted therein singly and in pairs in accordance with the divisions of ships bells, a count-wheel having a plurality of groups of notches arranged on the principle of ships bells, a single hammer acted upon in sequence by all of the said pins, a count-hook coacting with the count-wheel, and means for driving the said wheels at speeds determined in relativity by the number of groups of notches in the count-wheel.

4. In a ships bells clock, the combination with a pin-wheel, of pins mounted therein singly and in pairs in accordance with the divisions of ships bells, a coaXially-mounted count-wheel having a plurality of groups of notches, of which the notches of each group cover the entire cycle of pins in the pinwheel, a count-hook coacting with the countwheel, and means for driving the pin-wheel as many times faster than the count-wheel as the count-wheel has groups of notches.

In testimony whereof, I have signed this specification in-the presence of two subscribing witnesses.

FREDERICK WVEHINGER.
