CUCKOO-CLOCK.

SPECIFICATION forming part of Letters Patent No. 465,441, dated December 15, 1891.

Application iiled March 18, 1891. Serial No. 385.566. (Model.)

To CLM whom t may concern:

Be it known that I, THEODOR VEISSER, a subject of the Emperor of Germany, residing at Vhrenbach, Grand Duchy of Baden, Germany, have invented certain new and useful Improvements in Clocks, of which the following is a specification.

My invention has for its object to provide the striking-train of clocks with a device ro which will imitate the cry of the cuckoo by means of a single whistle at every action of the striking-train. This new arrangement, compared with the hitherto known construction of cuckoo-clocks, all of which are pror5 videdwith two whistles, presents the advantage that considerable less room is required, and that consequently cuckoo-clocks may be made of a size only half of that of the hitherto known construction, an advantage which is 2o highly appreciated by the clockmakers. Moreover-,thecuckoo-cryof myimproved clock is a great deal more natural.

In the annexed drawings, which form a part of this specification, and wherein like parts z 5 are designated by like letters of reference throughout all the figures, Figure 1 is a back view of a clock-work, the whistle being shown in section, the mechanism being in normal condition, portions being shown in dotted 3o lines. Fig. 2 is a plan view of the clock-work. Fig. 3 is a sectional elevation showing the mechanism in operating position, portion of the whistle being shown in section and portion in dotted lines. Fig. 4 is a detail of the 3 5 striking-wheel. Fig. 5 is a plan detail of what is shown in Fig. 4.

In the drawings, the letter S illustrates a clock mechanism mounted in the frame T, and which acts in the usual manner on the 4o striking-wheel A, which is provided with pro-A jecting pins a, as shown. 0n these pins rest the two levers B and C, the first B having for its purpose to open the key or valve 7s, while the second leverC serves to operate the bellows b. The lever C, which is forked at its front end, Fig. 5, is mounted on the arbor d, which arbor carries at its other end the lever D, engaged in a loop attached to the bellows b. The lever B is mounted on the arbor e,

and on the other end of this arbor is fixed the 5o lever E, engaged in a loop of the key-arm 7c. The whistle F, which receives the air from the bellows b, is tuned in such a manner that if the key is opened it produces the high sound of the cuckoo-cry and if the key is closed the low sound of the same. When the striking mechanism enters into operation, the two levers B and C are iirst raised, whereby the bellows h is inflated and the key 7U is opened, the forked lever C resting meanwhile with its lower prong on one of the pins a Iof wheel A, and when this wheel rotates this prong will of course be released from the pin, which causes the bellows to be half-way lowered, thereby producing the high sound of the cry. By the further rotation of the wheel the lever C is again slightly raised through its upper prong, and at the same time the lever B is released from the pin on which it rests, which causes the key 7c to be closed. 7o Slightly subsequent thereto the upper prong of the lever C is released from pin a, which causes the complete lowering of the bellows b, and thereby produces the lower sound of the cry, the key 7s being now closed. t A rod r is, as usual, attached to the bellows, which produces in a well-known manner the movements of the cuckoo. A lever s is provided to move the cuckoo laterally and is actuated by the clock mechanism. 8o

IIaving thus described my invention, what I claim as new, and desire to secure by Let'- ters Patent of the United States, is

l. In a cuckoo-clock, the combination, with a single whistle for producing the cuckoo-cry 8 5 and a key or valve therefor which is operatively connected with the striking-train of the clock by means including a lever coacting with the strikingwheel, whereby said key or valve is opened and closed during the operation of such striking-train, of a single bellows operatively connected with the strikingtrain by means including a forked lever, which in its co-operation with the strikingtrain imparts two impulses to the bellows, one of which passes through the whistle when the key or valve is opened and the other when it is closed, substantially as set forth.

2. The eombinatiomwith the striking-train Wheel A, and the free end of lever' D coactineluding Wheel A, provided with projecting ing' with a, loop on the bellows, substantlztlly pins, as shown, and a valved Whistle and :t as set forth. bellows in suitable Connection With each In testimony whereof I have signed my 5 other, 0f levers B and E, mounted on the same name to this specification in the presence of 15 arbor and cooperating, respectivelv,\vith the two subscribingr Witnesses.

pins of Wheel A and the arm of the valve of THEODOR WEISSER. the Whistle, and levers C and D, mounted on Witnesses: the same arbor, the lever O provided with FELIX S. JOHNSON,

1o two prongs which co operate with the pins of PAULO SELDEN.
