To all whom it may concern.-

Be it known that we, HENRY LBmrcemmnn and CHARLES G. ORTH, both of Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Striking-Clocks, of which the follow ing is a specification. I

This invention has for its object to provide a means for repeating the striking of the hour at any time between hours, and also for changing the striking from one hell to another every half hour. We attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of aclock mechanism having our improvements attached. Fig. 2 is a detached view ofthe repeating mechanism, and Fig. 3 is a detached view of the hammerchanging mechanism. These views are drawn full size.

A represents the supporting-frame.

B is the count-wheel connected with and 0p erated by the strikingtrain. This wheel is provided with stop pins b,projectingfrom the side of the wheel, and are in number equal to the twelve hours. These stop pins strike against the end of a spring, 0, attached to the frame A, as will be hereinafter shown in description of operation.

D is a lift-lever, which serves to stop the train by its book dropping into the deep notches, and is that of the construction now in common use. To accompany this liftlever is a second lever, E, pivoted tothe frame A at e, and is located beneath said lift-lever D.

F is a bent lever attached to a shaft,f, journaled in the frame A, its lower end reaching under the said lever E, its upper end standing above the frame, and is provided with a cord, f, passed out through the clock-case, by which said lever may be pulled,when desired,for the purpose of the repeated striking, as will be hereinafter shown.

The count-wheel has several pins, 1), attached midway between its center and periphery and located on its opposite side to those of b.

To the lower part of frame A is attached a spring, G,the upper end ofwhich bears against said pins, the purpose of which is to throw the count-wheel backward when the lift-lever is raised, said backward movement being limited by the aforesaid stop-pin b.

The operation of this is as follows: By the position of the count-wheel, as shown in Figs. 1 and 2, the clock struck twelve last. Now, by pulling on cord f lever F is drawn upon. This raises levers E and I), thus releasing the count-wheel. Then the spring G throws said count-wheel backward until stop-pin b strikes the spring C. At the same time levers D and E are lifted, a lever, H, on shaft 7c is also lifted. This carries upward a lever, L, on said shaft 7a, which catches a pin, Z, on wheel M of the striking-train, thereby arresting the forward movement ofthe train and giving time for the count-wheel to move back. Now, by letting go of the cord, the levers D and E drop again to their places and the hour before struck is repeated. This repetition may be struck as often as desired between hours, the change from one hour to the next being made in the usual manner. This repeated striking is limited to within five or six minutes of the succeeding hour to prevent the change taking place before the minute-pointer has reached the full hour. This is caused by means of a lever, I, attached to the same shaft that the lever F is, engagingwith ahook, J, on minutehand shaft Y, which prevents the lifting of levers D and E until said hook has passed over the meridian-point. Then theclock willstrike the succeeding hour, and will repeat that hour until the minute-pointer again passes around to within the five minutes before the completion of the hour.

The hammer-changing mechanism, the second part of our improvement, is described as follows: On shaft S, to which the hammer-la ver is usually attached, we put a sleeve, S, and attach the hammer-lever T to it. This sleeve is made to slide longitudinally on the shaft every half hour for changing the stroke of the hammer from one bell to the other. On the said shaft is also placed a spiral spring, S", the tension of which is to force the sleeve back upon the shaft. Said sleeve is moved by means of a lever, V, pivoted at its middle part to a stud, U, on the back frame, the lower end of said lever bearing against a lip on the end of sleeve S.

The lever V is actuated by a half-disk, V, on the back end of minutehand shaft Y. During one-half of the revolution of said shaft Y the said disk pushes and holds outward the 7 upper end of said lever V, the lower end forcing the sleeve S' forward on its shaft, thereby carrying the hammer forward, so as to strike the wire gong. During the other half-revolution the lever V is released from said halfdisk. This allows the sleeve to slide back on the shaft, thus carrying the hammer back. so that it will strike the second gong or bell. The object of this is to provide a different sound for the latter half hour.

Having described our invention, we claim as follows: a

1. In striking-clocks, the combinatiomwith the count-wheel provided with the two sets of pins b and 10, of the spring G and stop-spring O, the levers D and E lifted by lever F, which releases the hook of lever D from the countwheel, alsolifting the lever H, having the lever L,which engages with pin Zon wheel M, for arresting the starting of the striking-train while the spring throws the said count-wheel backward, said lever F also carries a lever, I, forward to engage with a hook, J, on minuteshaft Y at a given point in its revolution, the

operations of said mechanism enabling the striking mechanism to repeat the hour last, substantially as described.

2. In astrikingclock, the combination,with the repeating mechanism thereof, of the lever T, fixed to the sleeve S, and having the-upward extension engaging with and operated by the striking-train, said sleeve S being loosely placed on the hammershaft S, and made to slide thereon by the spring S in one direction, the other end of said sleeve having an extension bearing against the lever V,pivoted at its middle to the frame A, its upper end being actuated by the half-disk W on minute-hand shaft Y, by means of which the hammer-lever is shifted forward and back every half hour to cause a part of the repeated striking to be performed on the two bells, as described.
