GUSTAV ADOLF WVLOS'I, OF SCHRAMIBERG, GERMANY.

CHIMING MECHANISM.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed August 20, 1910. Serial No. 578,213.

To all whom it may concern:

Be it known that I, GUSTAV ADOLF WVLOST, workmaster, a subject of the King of Prussia, residing at Schramberg, in the Kingdom of VViirtemberg, Germany, have invented certain new and useful Improvements in Chiming Mechanism, of which the following is a specification.

In chiming clocks, regulators and so forth as heretofore constructed, as is known, the hammer striking against the gong, spring or the like resonator is rigidly connected with the hammer arbor. This, however, is disadvantageous in that, in the case of various clocks of the same kind, owing to variations in the fitting of the hammer and hammer arbor, in the bending of the wire and also in the mounting of the gong in the clock case, the hammer is not always situated at the same height above the gong, spring or the like. For this reason the tone is better in some clocks than in others, according as the accidental height of the hammer above the gong or the like corresponds with the conditions of resiliency of the hammer. For each clock movement, for each hammer and each gong there is only one correct position above the gong or the like for the hammer in which it gives the best sound and heretofore it has been impossible to predetermine this position. Another defect in the ordinary method of mounting the hammers resides in the fact that it is not possible to adjust the mechanism to obtain any desired degree of loudness and strength or softness and weakness. These disadvantages are avoided in accordance with the present invention owing to the fact that the hammer is adjustably mounted on its arbor so that according to the setting of the movement in the casing the hammer can be given any suitable position for obtaining the desired tone.

My invention is illustrated in the accompanying drawings, in which Figure l is a plan view of a part of a clock casing showing the same as applied thereto, the gong, spring or like resonator not being shown. Fig. 2 is a detail sectional view illustrating the manner of applying my invention, the yielding spring, however, constituting a part of the invention not being shown in this view.

Referring now to the drawings in detail, a part of a clock casing is shown, in which a represents a hammer arm mounted with its bushing 22 loosely upon an arbor 0 journale-d in the frame.

(Z is a stationary arm which is attached to or constitutes part of a collar h secured in turn around the arbor 0 by a pin 2', as shown, said arm being provided near its outer end with an adjusting or set screw 6.

g is a second arm either secured to or constituting a part of the striking arm a and located relatively at right angles thereto and normally substantially parallel with the arm (Z.

f is a spiral spring which is connected to both of the arms d and g and in such relation thereto that the adjusting screw 6 extends through the aXis of the spring.

The gong, spring or other resonant part of the apparatus is not shown, but would ordinarily be located below the clapper or hammer at the end of the hammer arm a, and it is the function of the parts described to so adjust the arm with relation to such gong, spring, or like resonant part as to effect the best results.

The operation of the device will be understood, it being apparent that when the device is set up for use the adjustment of the striking hammer with relation to the gong, spring, or other resonant part may be very accurately effected by turning the set-screw 6 either to the right or left so as to thereby effect a proper angular adjustment, the spring f withdrawing the clapper from relative close relation to the resonant partwhen the screw is turned to the left, said screw advancing it when turned to the right.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is In a chiming mechanism an arbor, an
